AREA of TECHNOLOGY

This invention relates to a mountain harvester, and in particular, though not exclusively, relates to the excavation of solid rock.

Background of the INVENTION

In U.S. patent No. 6561590, issued may 13, 2003, in the name of Sugden, which is used later in this invention, a description of the cutting device. Described in this patent, the device is a cutting device rotating (disk) podobnego type that provides improved rock excavation from the surface of the bottom and which is relatively economical from the point of view of production and operation.

In described in said patent the device is used to counteract the mass of sufficient magnitude, which amortizes the effort with a disk cutter to the breed during each cycle of the oscillatory motion with minimal or slight movement of this device or structure that is holding the device. Due to the fact that this device usually applies the load at an angle to the plane of the face, tearing at the rocks under tension instead of crushing them. Applied to the rock force for the specified tensile rupture, essentially, less effort, which is necessary for crushing, so that the required counter weight can also be soo�respectively reduced compared with known equipment for excavation of rock. Proposed in this patent disc cutter attached to the support structure, preferably located so that the reactive mass may be damping and cyclic peak loads experienced by the disc cutter, while the reference design provides a restoring force which is comparable to the average force experienced by the disc cutter.

Proposed in the mentioned patent, the device essentially requires lower applied forces compared with the known equipment for excavation of rock. Provides for a reduction of at least normal force, magnitude, or in some other important components.

Such small efforts contribute to the use of a support structure made in the form of a shoulder or arrows, which may introduce cutting edge disk cutter in contact with the rock at any desired angle and control the position of the disk cutter in any direction. In particular, with regard to the development of a continuous slaughter, the disk cutter, or a group of disk cutters can be fitted across the length of the plane of a longwall panel and with each pass to move forward in the main direction of removal. Mostly the specified device provides the input disk cutter in the plane of the bottom or from previous dredging in the development of long�of slaughter, or from the pre-made holes for access, or through the influence of breed at a small angle to the surface until, until required for the passage depth. If the disk cutter is mounted on a movable boom, then it can be moved in the plane of the bottom for rock excavating with this plane at any desired geometry.

However, when using such a disk cutter mounted on the end of the swing boom, there is one problem, which is to maintain the weight of the head disc cutter, simultaneous rotation of the boom at the angle of more than 180°.

Summary of the INVENTION

The purpose of this invention is to create a mountain harvester, which can be effectively used disc with an eccentric drive for the extraction of the breed.

Another objective of this invention is to create a mountain harvester, which can cut into the plane of the face by rotation of the boom at an angle of more than 180°.

The present invention provides the mining machine containing a cutting device having the arrow on the end of which is mounted a disc cutter, designed for interaction with the breed. Disc cutter is introduced by arrow in developing the breed, and the boom has a main part and a rotary �part b, pivotally attached to the main part.

DETAILED description of the INVENTION

Fig.1 depicts a longitudinal section of node of the disk cutter. The node 10 disk cutter �will win support unit 11 and the rotating disk cutter 12. Support unit 11 comprises a support shaft 13 which is rotatably mounted in the housing 14, which may represent a large mass or to be attached thereto to cushion the impact. Thus, the housing 14 may be made of metal or can be attached to a heavy metal weight. The shaft has a drive part 18 and part 20 to drive the disk.

Machine for rock excavating or mining machine in accordance with the present invention comprises a disk cutter 12 and is characterized in that the disc cutter is driven with ensuring move eccentrically. The amplitude of the eccentric displacement is directly proportional to the amount of displacement of the axis specified part of the drive for the disc from the center axis of the actuator part of the shaft, wherein, essentially, this value is relatively small. Preferably, the cutter 12 is driven by providing eccentric movement of relatively small amplitude and a high frequency component, for example, about 3000 rpm.

Inform the proposed disc cutter 12, the movement is such that normally the cutter acts on the rock at an angle and causes the destruction of rocks under tension, wherein the fragments are displaced from the surface of the rocks under the influence of the disk cutter. This the present invention differs from the disk R�scow roller type, which apply a force normal to the plane of the bottom with the formation of transverse cracks that create debris. The force required to fracture rock in tension and the displacement of a fragment of the host rock disc cutter is a value an order of magnitude less than that required when using the known disk roller cutters of the type for removing the same volume of rock, so that the inventive device is significantly more efficient in terms of energy consumption.

Disk cutter 12 of the node 10 preferably has a circular peripheral edge. The cutter 12 includes multiple spaced cutting bits or cutters 16, preferably made of tungsten carbide, which is attached to its circular peripheral edge. The peripheral edge of the disk cutter 12 is made with the possibility of free rotation relative to the oscillatory motion of the cutter, so that this edge can be rotated on the surface to breed. Thus, all parts of the peripheral edges of a cutting edge gradually come out of contact with the rock with cooling, and the wear is distributed evenly. Because of the relatively small contact force, the intensity of wear is reduced compared to the cutter roller type.

More specifically, oscillatory or exce�electric movement of the disk cutter 12 may be formed by any suitable method. In a preferred construction, the cutter 12 is mounted for rotational movement on the drive side shaft 18 driven by a suitable drive means (not shown), and part 20 of the disk drive, as will be described later. The axis of rotation of the actuator part 18 of the shaft offset from the axis of the portion 20 of the disk drive so that the cutter 12 is moved eccentrically. As shown in cross section in Fig.1, part.20 shows a thicker below the Central axis of the actuator part 18 of the shaft. The Central axis of the cutter 12 and the portion 20 of the disk drive is offset from the axis of the drive portion 18 of the shaft a few millimeters. The offset value determines the degree of vibrating (eccentric) movement of the cutter 12. This eccentric movement allows the cutter 12 to affect the developed material like a jackhammer.

In alternate constructions (not shown) could also be the angle of the cutter 12 simultaneously with its vibrations by the angular displacement of the axis of rotation of the actuator part from the axis of the shaft supporting section of the cutter 12, as described in U.S. patent No. 6561590, author Sugden.

Disk cutter 12 is mounted on the host 10 via support rotor 36. Support unit 11 comprises a housing 14 having a portion 19 to hold the shaft. The housing 14 also holds the bearing rotor 36. Part 19 has a longitudinal axis which coincides with the axis privode�about the shaft 13. Drive shaft 13 is mounted rotatably inside the part 19 on bearings 15 and 17, which may be of any suitable type and bearing capacity. The bearings 15 and 17 is established by any suitable method known to the expert.

One end 21 of the portion 19 to hold the shaft has a flat radially extending surface 23, to the outer periphery of which is attached to the retaining ring disc cover 25. At one end 26 of the bearing rotor 36 is a flat radially extending surface 27. The end 26 of the bearing rotor 36 is located adjacent to one end 21 of the portion 19 to hold the shaft, and these two ends 21 and 26 abut each other to ensure the maintenance of support rotor 36 and the disk cutter 12 with providing rotational movement of the disc 12 relative to the portion 19 to hold the shaft. The specified end 26 of the bearing rotor 36 is held in place by a cover 25 which passes over a part of the outer contour of the front end 21 for the installation disk. Between said one end 21 of the bearing rotor 36 and the cover 25 has a sufficient gap, providing eccentric movement of the rotor 36 and the disk cutter 12 relative to the cover 25. Lubrication holes (not shown) provide the oil film between the respective flat radial surfaces 23 and 27, and also serves smason�e substances to other moving parts inside the node 10 of the cutter. Disk cutter 12 is mounted on the support rotor 36 by suitable means of connection, for example, a threaded connecting elements 37. Cutting disc 12 can be removed from the node 10 for replacement or repair by removing elements 37.

Disk cutter 12 is mounted on the drive portion 20 of the shaft with the possibility of free rotational motion. Disk cutter 12 is mounted using a spherical roller bearing 39, which is located between the notch 40 of the shaft and the wall 41 of the support rotor 36.

Large bearing 39 is located directly in the line acting on the cutter 12 loads, being exposed to mostly acting on the cutter radial load. In the node 10 may use different bearings of any suitable type, however, are preferred anti-friction roller bearings, it's also possible the use of hydrodynamic and hydrostatic bearings.

When you move the disk cutter 12 applies a shock to the treated surface of the breed that causes the destruction of rocks under tension. Fig.2 it can be seen that the movement of the disk cutter 12 introduces a cutting tip or cutting edge 58 in the interaction at the point 59 of the breed 56 of the oscillatory movement. Such oscillatory motion leads to the displacement of the disk cutter 12 in on�governance, essentially perpendicular to the axis AA of the support shaft 13. Providing oscillatory motion causes the cutting edge 58 to strike the surface 59 is essentially in the direction S, so that in the rock, as shown, is formed in the chip 60. Subsequent fragments are shown by dotted lines 61. The impact of the disk cutter 12 on behind the surface 59 is similar to the impact bits when creating tensile stress in a brittle material such as rock, which effectively collapses under tension. The bearing 39 provides the opposition in the direction of S strike disk cutter on underneath the surface 59 of the breed.

Fig.3, 5 and 8 show the mining machine 100 (see Fig.8) in accordance with the present invention. The mining machine 100 contains a cutting device 104 with an arrow 108, 112 of which (see Fig.5) installed the first disc cutter 116 together with the great damping mass 127 (see Fig.5) and intended to enter into contact with the developed material. Cutting device 104 further comprises a second disc cutter 120 which is mounted on the end of arrows 112, located at a distance from the first cutter 116 and intended to enter into contact with the developing material, and a third disc cutter 124 mounted on the end of arrows 112, located at a distance from p�first cutter 116 and the second cutter 120 and intended to enter into contact with the developed material. More specifically, each of the disk cutters 116, 120 and 124, respectively, is part of the node 117, 121 and 125 (see Fig.5), as set forth above.

Disc cutters 116, 120 and 124 are mounted with the possibility of promotion to develop the breed. Accordingly, the mining machine 100 is installed, for example on wheels or rails or tracks, or tracks (not shown), wherein preferably the mounting equipment is located to prevent approximately average values of forces exerted by disc cutter while a large damping mass 127 (see Fig-5) counteracts the peak values of forces, as set forth below.

More specifically, as shown in Fig.8, the cutting device 104 further comprises a means for introduction of a disc cutter to develop the material, and these means include a forward platform 128 and the rear platform 130, the rotary means 132 for mounting the boom with providing rocking motion in a horizontal direction on the front of the platform 128, and a pull and a retractor means, located between the front platform and rear platform and is made in the form of a pair of spaced hydraulic cylinders 136 for moving the front platform 128 forward (developed material) relative to the rear platform 130, bogdashina platform 130 is fixed, and rear of the platform 130 forward relative to the front of the platform 128, when the forward platform 128 is fixed. Disc cutters on one side of the harvester 100 can be located on the conveyor 145 or a vacuum device (not shown) or both of these devices, as shown schematically in Fig.8, designed to remove excavated material.

Each of the disk cutters 116, 120 and 124 is pushed by an arrow 108 in developing the material by advancing the arrows 108 in developing the material using, respectively, first and second hydraulic cylinders 160 and 164 connected between the boom 108 and the forward platform 128. In other embodiments (not shown) may use hydraulic or electric rotary actuator which rotates the boom 108, which increases the amplitude of rotation of the boom. Arrow 108 also has the possibility of translational movement relative to the front platform 128 by setting the arrows 108, turning her means 132 and the cylinder 160 and 164 on the platform 168 arrows, which can slide in a guide rail (not shown) on the front of the platform 128 parallel development material. The cylinders 172, attached between the platform arrows 168 and the forward platform 128 is moved in the arrow 108 on the surface (sideways) relative to the front platfor�we 128.

The mass of each of the disk cutters are relatively much smaller than the mass 127, intended for cushioning the load. The load acting on each cutter during its contact with the rock surface during the oscillatory movement, perceived or depreciated due to the inertia of the large mass 127 and not the arrow 108 or other support structure.

More specifically, as shown in Fig.3 and 5, cutting device 104 contains an arrow 108, a large mass of 127 in the form of a cutter head, and the bracket 176 for mounting the head 127 to the boom 108. Head cutter 127 is an enclosure containing three nodes 10 disk cutters. More precisely, the cutter head has three holes 180, 182 and 184, each of which, respectively, are located with the possibility of dismantling, in the usual way, one of the disk cutters 116, 120 and 124 and their corresponding nodes. The internal volume of the cutter head, surrounding three holes filled with a heavy material such as cast or precast lead 186, as shown in the sectional view of the head 127 of Fig.6. Front and back of each disc cutter in the direction of the development of the breed has water nozzles 129 (see Fig.3 and 5), helps clean the material with the cutter. Since a large total weight is distributed between the three disc cutters, requires a smaller total weight and, consequently, the mining machine 100 is more easy to�Nachnem. In a preferred embodiment of the three cutter distributed about 6 tons, with each cutter has a diameter of about 35 cm In other embodiments can be used with disk cutters of a smaller or larger size.

To the boom 108 suitable means attached to the bracket 176 (not shown), for example by welding. The bracket 176 is attached to the head 127 by means of two U-shaped profiled elements 190 and 192. In each of these elements is placed a flange 194 that is located on the head 127 and the flange 196 that is located on the bracket 176, which provides the attachment of the head to the bracket 127 176. As shown in the srig.7, between the head 127 and the bracket 176 is placed an elastic bushing 200 to prevent the transmission of vibrations of the cutter head arm 108.

As shown in Fig.9 and 10, the means 132 for rotary arrows 108 providing rocking motion in a horizontal direction on the front of the platform 128 contain the rotational axis 204 for vertical movement downward arrows 108. Rotary means 132 contain composite reference axis 208 with the upper axis 209 attached to the top of the boom 108, and the lower axis 210 that is attached to the bottom of the boom 108. More specifically, the rotary tool 204 includes a housing 216 of the upper spherical bearing and the housing 224 of the lower spherical bearing. Arrow 108 is installed within�and on the top axis 209 using the top spherical bearing 211, located between the housing 216 and the upper axis 209, and on the bottom axis 210 with the lower spherical bearing 213 located between the lower bearing housing and the bottom axis 210. Each of the wings 216 and 224 of the spherical bearing is held in a fixed position relative to the platform 168 arrows through slots 228 and 232, as shown schematically in Fig.10.

To move vertically downward and upward arrows means 108 204 contain the lever 234 is attached to the housing 224 of the lower spherical bearing, the axis 236 that is attached to the lever 234 is pivotally attached at its base to the platform 168 of the boom, and means for turning the lever, made in the form of a hydraulic cylinder 237, installed between the upper part of the axis 236 of the platform and the boom for the rotation of the housing 224 of the lower spherical bearing and, accordingly, rotation of the boom 108. A similar lever and the axle attached to the platform 168 (not shown) attached to the opposite side of the housing 224 of the lower spherical bearing thereby providing a fixed point of rotation of the node.

Work mountain harvester 100 is carried out by advancing the arrows 108 by means of a hydraulic cylinder 136 to develop material on a first incremental distance, the vibrational motion of the boom 108 to plunge in �the material, and then promote the arrows 108 to develop the material for the second incremental distance, which is equal to the first distance. As a result, the contact between the head of the cutter 127 and develop mineral is minimized. During return of the boom 108 to the starting position of cutting the boom 108 is slightly withdrawn back (approximately 4 cm), to prevent contact of the head with the surface 127 of the face during return of the boom.

Fig.11 to 20 show another embodiment of the arrows 300 mountain combine. If in the first embodiment, the arrow 108 can be rotated at an angle of about 120°-150°, in this embodiment, the arrow 300 can be rotated through an angle of about 220°.

Shown by the arrow 300 in many respects similar to the arrow 108 of the first embodiment shown in Fig.5, except that in this case, the swing arm 300 includes a main portion 304 and a turning portion 308 is pivotally attached to the main body 304, and More specifically, the main portion 304 includes two spaced horizontal main plate 312, between which is rotatably mounted and is held bearing 316. The rotary portion 308 is attached to a support 316 and can be rotated with respect to part 304 by rotating around the support 316.

The rotary portion 308 includes two spaced apart support plates 322, attached to a support 316, andtwo spaced rotary plates 326, spaced parallel support plates 322, but is offset from them in the outer radial direction.

The support bracket 176 cutter head attached to the rotary plates 326.

For the rotation support plates 322 relative to the main portion 304 between the main part 304 and the rotary part 308 are two spaced hydraulic cylinder 324 and 328. One cylinder 324 is attached to the base plate 322 with one side of the support 316 and the other cylinder 328 is attached to the same plate 322 on the other side of the support 316. Through the nomination of one of the cylinder and retraction of the other cylinder rotatable portion 308 can be rotated relative to the main portion around the support 304 316.

For the rotation of the rotary plates 326 relative to the supporting plate 322 on the lower supporting plate 322 is equipped with a hydraulic swivel cylinder 334 which passes between the support plate 322 and the rotary core 340 (see Fig.19) attached to the spaced rotary plates 326 and extending between them, wherein the rod 340 is inserted into the curved groove 344 in the support plates 322 and passes through it.

The rotation of the rotary plates 326 of�SyteLine support plates 322 is provided by the extension or retraction of the hydraulic cylinder 334.

Fig.11-20 shows the sequence of the turning movements that cause the rotation of the cutting device 104 by more than 180°. More specifically, Fig.11 shows that the left main hydraulic cylinder 328 is retracted, and the right main hydraulic cylinder 324 is advanced. The device 104 is located in a position approximately eight hours, if you look down from the top of the boom. In this position, the rotary cylinder 334 is in the retracted position.
