The invention relates to a device for milling, in particular rocks or other materials, containing mounted on a support for rotation around the axis of the spindle drum, which is installed eccentric to the axis of the drum with the possibility of bringing into rotation around the spindle axis several tool spindles, bearing on their projecting from the spindle drum ends of the machining tools. In addition, the invention relates to a method for milling of rocks or similar materials using such a device.

For milling rock or other hard materials, such as products produced in underground or above-ground mining, asphalt or concrete parts in the construction of roads or buildings or the like, it is known a large number of milling systems, which in most cases are driven in rotation by the drums or discs on the circumference which are arranged with a uniform distribution milling tools, such as disc cutters. When using such provided on its periphery milling tools drum mined with the help of the Shearer drum-the Executive body of rock or coal in an underground mine workings, and a screw or drum IP is ornately body cuts or preserue with a full incision to be production material, about half of all located on the circumference of the drum machine tools is simultaneously engaged. Each machining tool with full cut for half of the turnover, i.e. 180, is engaged with the subject treatment material, which leads to the fact that in more solid materials solid carbide top of the tools are heated to very high temperatures and wear out quickly.

Another disadvantage of the known machines is that full clamping pressure with which the drum is pressed against the rock, is distributed to a large number of separate tools, so that for each individual in the operation of the cutter is available in only a relatively small clamping force. When, for example, the total clamping pressure drum on the rock is about 2000 N, and with the full cut in the work there are always about 20 separate instruments, each individual in the operation of the tool is available, on average, only clamping force of 100 N. In addition, using known devices, in which the tools are still around the circumference of the roller or drum, it is difficult to cut in the axial direction to be processed material that is explained by the fact that the optimal cutting speed meets is on the outer diameter of the rollers, and the cutting speed stronger decreases in the direction of the axis of rotation of the drum or roller and near the axis of rotation becomes so small that there is cutting almost impossible. Even if the drum is equipped with instruments on their side, they in the axial direction of the drum do not cut in front of them end side of the rock.

From DE 34 45 492 C1-known drilling head for drilling in rock, which has a device for fastening tools, drilling tools, which relies on a Central shaft, which is connected with passing between the borehole and the drill head drill rods. Drilling tools on this device are rotated through the planetary gear set.

Object of the invention is a device for milling of rock or other materials specified in the beginning of the species, which is able to handle also very hard materials with high performance milling in comparison with conventional driven tools provided spindle drum clamping effort is reduced, and increases the service life of tools. The device according to the invention has, in particular, have high operational reliability, to be compact and provide them the ability to host machine tools of various kinds, such as, for example, a milling roller, a blade, satyavani tools or the like, of any weight and size.

This problem is solved according to the invention using the specified in the independent claims of the signs. Due to the fact that at least two of the tool spindles are driven from a common drive through the gearbox, which is mounted rigidly on the tool spindles driven gears and a common drive element, in particular a drive gear or drive chain, drive toothed belt or the like, while the actuator interacts with the driven gears, and the drive element and the spindle drum set can be rotated relative to each other, creates a particularly compact arrangement of the device in which at least two of tool spindle with associated tools can to synchronously operate outside the middle axis of the spindle drum. When placed on tool spindles machining tools can be easily set so that even when the entire section with the link in 180 only one machining tool or only a small number of instruments are simultaneously in engagement, so that the full available prigin the e force of the spindle drum can be used only one or only a few instruments, thus, just being in engagement in the rock a separate tool has a very large force of wedging.

It is possible that the spindle drum has a rotational drive that is not connected with a drive through the gearbox. Thus, in this embodiment, the spindle drum is driven by the rotary actuator and the tool spindles are rotated independently of the rotation speed of the spindle drum. In this embodiment, even when the axial flow device in rock, at least for a short time, just to stop the spindle drum, only by rotating tool spindles to drill in the rock a small area and only then enable the drive for the spindle drum.

It was found that particularly preferred if the spindle drum and at least part of the tool spindles have a common rotational drive, so that by rotation of the spindle drum automatically are rotated and having a common rotational drive tool spindles.

In this regard, is structurally preferable if educated driving toothed wheel of the drive element is located relative to the support drum without the possibility of turning and, in castnet is, rigidly connected to the support drum. In this case, rigidly mounted on the tool spindle driven gears are in engagement with located without the possibility of turning on a support drum drive gear, thereby clamping spindles are rotated when the spindle drum hosting tool spindles is driven into rotation from the rotary drive. Using a planetary transmission is possible in a particularly compact design to transmit very large forces and torques.

Instrumental spindles preferably installed in the bearing bushings with bearings rotatably and appropriate sealed using seals. Especially preferably in such a system, if the supporting sleeve with installed with the possibility of rotation of the tool spindles installed by type cartridges with replacement and fixed in provided on the spindle drum cameras. In this case, the tool spindles can be replaced in blocks with their bearings and, if necessary, seals through simple replacement of bearing bushings, for example, worn or when it is necessary to apply the tool spindles for other machining tools. Instrumental pendeli pre-mounted in the bearing sleeve, so the removal and installation of these units in the spindle drum occupy only a very short time.

Preferably all tool spindles are driven through a common drive gear wheel of the drive through the gearbox. However, it is possible that the first group of tool spindles is driven through the first common drive gear wheel, and the second group of tool spindles is driven through the second common drive gear wheel, for example, when the first group of tool spindles is located on the spindle drum for dividing the circumference of the larger diameter, and the second group of tool spindles is located on the spindle drum for dividing the circumference of the smaller diameter. In this case, the gear ratio between the tool spindles of the first group and the first driving gear wheel and the tool spindles of the second group and the second driving gear wheel and/or direction of rotation of the tool spindles of the first and second groups may be different. As mentioned above, the tool spindles of the first group and tool spindles of the second group can be located in the spindle drum at different radial distances from the axis of the drum, i.e. lie on two different share is lnyh circles.

Instrumental spindles are preferably in the spindle drum with a uniform distribution on the perimeter.

In a particularly preferred embodiment of the device according to the invention it is possible that one or more located on the tool spindle machining tools are offset by several degrees relative to the location of one or more machining tools lying in the circumferential direction of the drum in front of or behind the tool spindle. In other words, machining tools following each other in the circumferential direction of the spindle drum tool spindles can be arranged with a phase shift relative to each other. This option allows execution is particularly preferred to provide in the process of milling of rocks according to the invention, which is located on the tool spindle, a separate tool comes in contact with to be processed rock in a different place than a separate tool lying before him in the direction of rotation of the spindle drum tool spindle. Thus, due to the placement of instruments with phase shift provided that the collision of separate tools sludge is different cutters tool spindles are not the same, and the next tool handles rocks in place, which left untouched the tools before passing it through rock instrumental spindle. This ensures a particularly effective treatment of rock or the like, For as accurate as possible achieve the desired phase shift or angular displacement of the machining tools is preferably mounted on the tool spindle with adjustable, i.e. they can be adjusted in their angular position relative to the tool spindles.

Processing tools may have one or more processing incisors, respectively, separate tools for each tool spindle. At least part of the individual instruments may in a particularly preferred embodiment of the invention consists of cutters with round rod, for some purposes the use of proven tools with flat blades or roller cutters, in particular, is made with one side conical roller cutters. For many purposes the treatment was preferred, if the machining tools are in the radial direction beyond the outer circumference of the spindle drum maximum of 50% of district machining surfaces, i.e. if maksimalno half of the individual machine tools tool spindle is simultaneously in engagement with the rock or similar

Spindle drum may be preferably provided with a centrally located hole for removal of dust, through which you can take occur when milling rocks or the like fine dust. Also preferably, if the device is equipped with at least one nozzle of the irrigation device for machine tools, with which, on the one hand, binds dust arising due to the spray in place of water treatment, and, on the other hand, is also provided with a cooling machine tools. Spray irrigation device is preferably located on the spindle drum and/or on the support drum.

In the device according to the invention can be applied machining tools of various kinds. For example, it is possible that the machining tools of one or more tool spindles essentially consist of media cutters and a few placed on it incisors with a round rod, flat cutters and/or roller cutters, and they are so arranged on the tool holder tool tools handle the rock or other material in one or more layers of backing. The arrangement is chosen so that the employed multi tool tapers preferably stepped to the NRA is the t to be processed rock. Machining tools can also consist essentially of the milling drum of the Executive bodies, which are located on one or more tool spindles. These milling drum of the Executive bodies may be made cylindrical or conically shrinking or expanding in the direction to be processed rocks.

If the drive element consists of having outside teeth of the drive gear, which is connected with the support drum, the direction of rotation of the tool spindles equally with the direction of rotation of the spindle drum. If the actuator consists of having inside teeth of the drive gear, which is connected with the support drum, driven in rotation in such a driving toothed ring tool spindles rotating in the opposite direction relative to the direction of rotation of the spindle drum.

For decoupling the rotational drive for the spindle of the drum from the gear drive for the tool spindles are especially preferred is a structural variant of execution, in which the spindle drum is held coaxial to the axis of the drum, a feed opening for the drive shaft, which is mounted rotatably in the receiving hole and is connected with PR is a water element for the tool spindle. Drive shaft, thereby, is mounted for rotation concentric to the spindle drum, which provides not only compact, but also high structural stability. For this purpose the spindle drum may have a sealed enclosure with about steinebrunner the main body of the drum and the housing cover, with the drive element, that is, in particular, the driving toothed wheel, is placed inside the main body of the drum, is connected to the drive shaft and closed the cover.

Gear motor for tool spindles preferably hermetically located in the spindle drum. Machining tools can build a cantilever manner with their respective tool spindles on the spindle drum and to speak from the front side and/or from the perimeter of the spindle for the drum.

To facilitate the cutting device in the axial direction in the rock turned out to be preferred, if the spindle drum in addition to located with the distribution of its circumference instrumental spindles with milling tools provided inside the described tool spindles dividing the circumference of the Central milling cutter, which is preferably located with a small eccentricity relative to the axis b is Rabanne. Using configured to drive the Central cutters can provide milling all located in front of the front side of the spindle drum rocks for bumping into him the device in the axial direction.

To ensure stable placement tool spindles machining tools with their respective tool spindles mounted on the spindle drum, preferably by using a two-point support. This can be provided by mobile and fixed support, as an alternative solution you can also use an adjustable support, in particular with X-shaped arrangement, for example, by using tapered roller bearings or the like

In particular, the application of machine tools with a relatively large axial length, for example, instruments with a long shank, particularly preferably, if the spindle drum is approximately plate-like abutment flange near the support drum to accommodate the first pillars of tool spindles and which is concentric with the axis of the drum carrying the axle, on which is located, at least one supporting element for placing second supports tool spindles. In this case, Chuck rock zone machining tools are m is waiting for both of the supports, what is especially stable support. In this embodiment, the invention may be further useful if the support element or carrier trunnion is located concentric with the axis of the spindle drum, an anchor pin for extra support spindle drum. In this case, the spindle drum set with two-point support, i.e. to provide at the opposite pole of the drum end of the additional support and thereby prevent sagging that can occur with long instruments and console mount.

The support element may be located on the end side of the bearing axle blank flange, which is provided with support slots for the second leg. In this case, the machining tools are closed from the front side blind flange and handle the rock only a few tools that are located on its circumference, and act in the radial direction between the plate-like supporting flange and blind flange spindle drum. Can be provided by two of the support element, which are located at different distances from the support flange, and in which the second support different tool spindles. With this arrangement, the second support tool spindles are the and the distance from located on the side end face (free) end of the machine tools, which in this case can cut into the rock by its end sides.

To prevent damage to the device due to overload proved to be expedient to connect the actuator with the support of the drum through a safety clutch, which may be, for example, spring-loaded slipping clutch. While acting on the clutch spring load can be adjusted and thereby to set the threshold at which the clutch is disconnected and the drive element slides over the support drum.

Spindle drum may be at its opposite processing tools side features a removable, sealed relative to the support drum with the gland end cap that provides access to the underlying gear drive and other parts, which from time to time it is necessary to maintain and verify.

In General, the axis of the tool spindles in the spindle drum is oriented parallel to the axis of the drum. However, it is also possible to arrange the axis of the tool spindles with an inclination relative to the axis of the drum, which can further improve the result of some milling to be processed rocks or materials. In another embodiment, each processing tool being the equipment has a number of evenly spaced around the circumference of the machining tool of separate tools and mounted on the respective tool spindle using the clasping clutch, while the number of possible positions of the fixing latch coupling so consistent with the number of individual tools on the machining tool, they are in each fixed position are in the same position relative to the tool spindle. Clasping the clutch is triggered when the machining tool is blocked rock, in which he crashed, so corresponding to the tool spindle, which carries the tool can be rotated further in the following locked position, in which the machining tool is again recorded and can be rotated further. When this machining tool again is fixed in a position in which its position relative to the machine tool adjacent tool spindles remains the same, i.e. initially set the phase shift or offset machining tools successive tool spindles remains unchanged when triggered latch coupling and re-fixing of the tool.

The device and run it using the method, respectively, particularly preferably suitable for the production of mineral products such as coal, ore or the like For this purpose, the device can be used as a substitute itself known tool to the Ronchi mountain harvester or cutting head of the machine with partial or complete destruction. The device and method according to the invention can be successfully used also for processing betonirovannaa or paved surfaces or buildings, for example, when milling asphalt or betonirovannaa street coatings for the demolition of concrete structures or the like, Often for different purposes, it is preferable if the device according to the invention mounted on an adjustable console and with it set at to be processed rocks or the like can also be used in devices according to the invention in small devices, such as hand-cleaning milling devices.

Shown in the drawings various embodiments of the device according to the invention, which is indicated in General position 10, are used for milling rocks such as mineral mined products such as coal or ore, or for processing concrete, asphalt or other building materials, such as milling street coatings or the like When matching the design to the active parts of the various embodiments of the device according to the invention, the repeated description is not given. Moreover, after a detailed description of the fundamental designs with links to 1 then essentially explains only the differences between the various embodiments.

As shown in figure 1, the device 10 according to the invention has a support 11 of the drum for mounting on a suitable casing of the machine (not illustrated), for example on the console mining Shearer street or milling machine. Bearing 11 of the drum has a Central bearing socket 12, in which the spindle drum 13 is mounted for rotation of its supporting trunnion by means of two tapered roller bearings. Its rear end 16 of the supporting pin 14 protrudes from the rear of the base of the socket 12 of support 11 of the drum and is there a driving wheel 17, which is for rotating the spindle drum is connected (not illustrated) to drive the rotation.

At its other, opposite the drive wheel 17 the end of the support pin 14 moves in a circular plate-like flange 18 of the spindle drum near its outer circumference is shown in the exemplary embodiment, six located with uniform distribution on dividing the circumference of 12, camera 20 of the drum. In each cell 20 posted by drum support bushing 21 is installed with the possibility of rotation of the tool spindle 22, while supporting sleeve installed in them & what other spindles in the form of cartridges are inserted with the possibility of replacement in the corresponding chamber 20 of the drum and fixed in situ by means of fixing screws 23. At its rear end, which tool spindles are at the rear of the base flange 18 of the spindle drum, they are driven by gear wheels 24, which are in engagement with a drive gear wheel 25, which is rigidly secured to the support 11 of the drum is provided in the socket 26 for gears with screws 27. Shown in figure 1 the first example you can see that the sprockets driven gears 24 tool spindles 22 are rolled by still mounted on the support 11 of the drum drive gear wheel 25 when the spindle drum 13 rotates with the drive wheel 17 provided for this purpose, the rotational drive, so due to this are rotated also instrumental spindles. With this construction, there exists a constant gear ratio between the driven spindle drum 13 and mounted therein for rotation synchronously driven in rotation through the gear box 24, 25 tool spindles. With a transmission ratio of, for example 10:1, tool spindles rotating at a speed of 500 rpm, if the rotation speed of the spindle drum is 50 R/min Gear ratio can be changed by changing the diameter of the drive gear stake and the driven gears, accordingly, changes in the number of teeth. You can remove the drive gear 25 and replace it with a smaller toothed wheel, while at the same time you set any other tool spindles with increased driven gears.

For mounting the entire device 10 provided for the machine frame (not illustrated), such as, for example, the harvester with the drum by the Executive body or street milling machine, on a support 11 of the drum is provided mounting holes 28 for mounting screws through the provided in the bearing flange 18 of the tool spindle 13 holes 29 are inserted into the mounting holes and using a suitable tool, such as, for example, a key with an internal hexagon, are screwed into in line with the mounting holes 28 of the screw holes on the machine frame. Thus, the entire device can be quickly mounted on the machine frame without dismantling any parts of the device.

In addition, as shown in figa, the mounting flange 18 of the spindle drum 13 on its rear side provided with a cover 30 of the housing, which is screwed to the support flange 18 and together with it forms a closed housing 31 for gear drive 24, 25 tool spindles. To prevent proniknovenie the moisture or dirt into the housing 31 of the cover 30 of the housing provided at its radially inner edge of the seal 32, which is sealed relative to the support 11 of the drum.

The front protruding from the free side of the spindle drum the ends of the tool spindles form a conical socket 33 for machine tools, various designs are shown in figure 2-14. All these different designs of machining tools can be applied also shown in figure 1 embodiment, the device according to the invention, as will be described in detail below.

Shown in figure 2 embodiment, the device according to the invention it is possible to set the rotation speed and rotation direction of a separate tool spindles regardless of the speed of rotation and direction of rotation of the spindle drum. For this purpose the spindle drum 13 has a rotary drive that is not associated with gear driven tool spindles. Structurally it resolved that the spindle drum 13 is held coaxial to the axis 34 of the drum receiving hole 35 to the drive shaft 36, which is mounted rotatably in the receiving hole with two cylindrical roller bearings 37. The front support flange 18 of the spindle drum forms a closed housing 31 with approximately steinebrunner the main body 38 of the drum and the cover 30 of the housing, the drive gear 25 gear drive for the tool spindles installed without turning on the drive shaft 36 and are accommodated in the housing 31 between the main body 38 of the drum and the cover 30 of the housing. There it is engaged with the driven gears 24 tool spindles 22.

On the rear end of the drive shaft end provided with a toothed wheel 39, which is installed with the possibility of connection with the driving motor spindles (not shown), for rotation of the drive shaft 36, and thereby mounted thereon a drive gear 25 on the inside of the spindle drum, and to provide rotational drive tool spindles, while the rotation speed of the tool spindles can be set regardless of the speed of rotation of the spindle drum.

In the shown figure 2 example of execution tool spindles are not placed in the bearing sleeve and is inserted in the form of bullets in the chamber on the spindle drum, and a separate shafts mounted directly in the spindle drum, while the rear of the respective two tapered roller bearings located in the main body of the drum and the front end located in the direction of the handle bearing, is located in the cover 30 of the housing. Sealing the spindle of the drum relative to the support drum 11 is in this example of execution with the gland 40, which is located in the transition zone of the support flange 18 in the pivot pin 14.

As processing tools 41 in the example done the deposits according to figure 2 apply cutting the crowns 42 are installed on each of the six separate tools 43 in the form of drum cutters, however, they are located so that a given shock tops 44 of the individual instruments 43 working circle 45 machining tool is in a relatively small segment at the outer circumference 46 of the spindle drum, so that in the example run no more than two separate tools 43 are simultaneously in the radial direction beyond the outer circumference 46 of the spindle drum. The described individual working circles 45 six machine tools 41 circular line 4 specifies the diameter of the milling device in the rock, i.e. the zone in which machining tools their separate tools handle the rock. You can see that no more than 1/3 of all individual instruments in each moment of time is in engagement with the rock on line 47 milling, i.e. each tool destroys rock a maximum of 1/3 of a patent with each turn of the tool spindle ways and experiences associated with that load.

Figure 3 shows the device according to figure 2, is equipped with machining tools 41 in the form of a conical, two-stage drilling cutters 48, which are located one behind the other in the axial direction of the fixing circles of different diameters have six separate instruments 43. Drilling milling in the operation of the device the VA is milled in two steps through the rock 49, while located in the radial direction from the outside machining tools cut into lying closer to the device the first working circle 46a and located radially inside the instruments cut in the rock formed more deeply in the rock the second working range 46b. Here you can also very good to see that due to the imposition of rotation of the spindle drum 13 and the rotation of the tool spindles separate tools 43 are really only a very short time are in engagement with the rock formation, which significantly reduced the tool wear compared to conventional electric rollers or the like Instead of the location of the two steps can, of course, to choose individual tools location in three or more stages, in order for one stroke by moving the device in the lateral direction to cut off the backing rock or another to be processed material. The flow in the axial direction in rock usually does not cause problems.

Shown in the figure 4 example, perform processing tools are tail cutters 50, which are still connected with the respective tool spindle 22 carries a shaft 51, on the circumference of which there are separate tools 43, which is s can be, for example, placed in suitable holders tool cutters with round rod. In this embodiment, the individual tools are preferably located with the distribution in a spiral along the length of the supporting shaft 51, the arrangement can also be performed on multiple spirals. With this arrangement possible slight incision in the axial direction to be cutting the material and then moving the device in the lateral direction for cutting the material on the depth of the filing, respectively, the length of the tail cutters. For easier cutting, i.e. feed in the axial direction, it is possible to reduce the diameter of the instruments, at least in their front towards the rock area to the side.

Figure 5 can most clearly see the preferred principle of the device according to the invention. While the spindle drum rotates in the direction of the arrow And with the first rotation speed, for example, 50 rpm, a separate tool spindles are rotated synchronously with the rotation speed corresponding to the selected ratio, namely versions of the device according to figures 1, 3 and 4 in the same with the spindle drum rotation direction. When the accepted ratio of 1:10 speed of rotation of the tool spindles with what is 500 rpm You can see that the first machining tool 41A, which cuts into the subject to milling rock 49, and his four separate tools knocks rock 49 in a certain rhythm or within a certain distance of the recesses 52. Next machining tool 41C knocks the rock between the holes 52, through which approximately semi-circular edge 53 milling in the rock formed by the wave profile 54. Then the following processing tools 41P and 41D are demolished speakers, shown shaded in the top 55 in the wave profile, which edge milling maximum smoothed, and in the further submission of the spindle drum in the direction of arrow 56 this process can be repeated using machining tools E-N. However, as an alternative solution you can use tools E-N for further smoothing of the edges 53 milling in the rock. On the other hand, depending on the reduction ratio and the number of separate tools 43 on machining tools, the first processing tool, such as tool 41A, performs pre-cutting, following the tool cuts remaining between the recesses 53 of the zone, then the next in the circumferential direction of the drum instrument is Nova as the first tool emboss the new recess 53, and the next tool preserue remaining between zones. The image in figure 5 is chosen as if the instruments 41A-D at about the same time get it in to be cutting rock 49, which in practice usually does not occur. Tests have shown that particularly preferably, when the tool is shown in the case of machining tools 41A-N - configured so that when it is shown engaged in 180 (full cut) always only one single tool of all (five) generally working machine tools in the area of 180 edge 53 milling is engaged with the rock, because in this case you can use all provided by the device on the spindle drum, the contact force or the filing of only a single tool without distribution, as in the prior art, several cutters. In a preferred embodiment, the machining tools are positioned and adjusted so that the corresponding next tool no cuts just created in the previous tool path in the rock, and offset.

Another embodiment of the device according to the invention is shown in Fig.6. This alternative implementation is based on the device according to figure 1 and differs from it by mounting a drive gear 25, which are carried the building driven gears 24 tool spindles. In an embodiment according to Fig.6 drive gear 25 is connected to the support 11 of the drum through a safety clutch 57 which provides a frictional connection between the support 11 of the drum and the drive gear 25 through the pads 58 of the clutch. Torque actuation, which triggered a safety clutch and drive gear 25 begins to slip relative to the support drum can be adjusted. For this purpose on the support drum can be adjusted on the adjustment ring 59 with a thread 60 in the direction formed by the linings and the intervening portion of the drive gear 25 of the clutch pack with the aim of tension disc springs 61, which with a uniform spring load acts on the circumference of the clutch. With this construction is provided to prevent damage to the device when locked which cut into the rock by the tool, as in this case triggered a safety clutch and separates all machining tools from a common drive spindle drum and tools until you fixed the lock corresponding to a specific tool due to rotation of the spindle drum. This maintains synchronization of the individual machine tools with each other, because prorabatyvanie clutch they all remain in engagement with the driving toothed wheel.

In the shown figure 7 embodiment, the device according to the invention also uses a safety clutch, which is made exactly the same as in the example of execution according to Fig.6. However, shown in the figure 7 embodiment, the tool spindles selected drive separate from the drive spindle of the drum. For this purpose on the support 11 on the front support segment 11A is installed with the possibility of rotation of the drive ring 62 which at its outer circumference shall be mounted through a safety clutch 57 drive gear 25. In his in the axial direction of the rear area of the drive ring has an internal ring gear 63 in mesh with which is a drive gear (not illustrated) of the drive tool spindles to ensure rotation of the drive ring on the support 11 of the drum and thereby the rotation of the tool spindles.

On Fig again shows the device according to figure 1, but with machining tools in the form of cutting plates 64, which consist essentially of about telcobridges supports 65 and four evenly spaced around the circumference of the support blades 65 and 66, which are mounted rotatably in a bearing 65. When this location is selected so that the axis of rotation of the discs 66 are not parallel to the axis of rotation of the installed bezothodnosti turning on the respective tool spindle bearings 65, and with a slope inwards towards the rock, so that when the cutting blades in rock 49 end side of the cutting discs do not come into contact with rock, and it is ensured that the cutting discs 66 handle the rock is really only its circumferential cutting edge 67. However due to the installation with the possibility of rotation of the cutting disks in support of the cutting plates is ensured that the cutting discs along its cutting edge roll on the created edge 53 milling in the rock. In one preferred not illustrated modification this option, perform the individual cutting disks on each cutting plate can be connected to each other through suitable connecting body, as, for example, belt drive, or inside bearing gear, is provided so that when rotating tool spindles come into engagement with the rock a separate tool (cutting wheel) already has a circumferential velocity equal to just leaving gear in front of him a separate tool, so there is not the sudden acceleration of the blade in contact with the surrounding rock and is associated with these possible damage to the disk. Used in an embodiment according to Fig.7 machining tools are especially suitable for not is how many more processed soft rock as, for example, in coal mining.

Shown in Fig.9 example of execution axis 68 of the tool spindles 22 are not parallel to the axis 34 of the spindle drum 13, and with a slope inwards towards the rock. For this purpose, the supporting sleeve 21 is drilled with an inclination to accommodate installed in them tool spindles, and drive gear 25 is made in the form of a conical wheel, in which rolling is performed on tool spindles driven gears 24 inclined tool spindles.
