Description

The present invention relates to Oistamo to combine with screw or the drum by the Executive body.

Shearers with screw or the drum of the Executive authority are in the mining industry the most commonly used mining machines. The design of these machines and products have been optimized over many years. However, it was adopted at the present day design capacity less than 1.4 m can be used only with restrictions. The fact that the power of the motor with increasing amounts of increases or decreases the volume drops dramatically limits the available power of the engine when the same design treatment combines with a screw or the drum by the Executive body at low altitudes floor. Along with the available capacity of an important criterion for the design of powerful machines are primarily boot features.

The total capacity of the machine is limited by the geometry. Special obstacle here for already available machines are the following circumstances: low power motor drive cone digging machine, low power winches, self-driven, low stability of the machine (runs or jumps), bad boot characteristics (the small Popper is a great cross-section of the channels for the transportation of coal in felling, blocking flow of coal lever, a small tunnel under the car, because cars are above the conveyor in the form of the bridge, lower the speed with which the panels can follow roller and low speed, which reaches the driver of the harvester during operation of the machine.

Harvester for the extraction of minerals are described, in particular, in SU 1209846 A. This harvester is equipped with a screw Executive body for extraction by underground mining, machine body, movable along the conveyor, and at least two cutting rollers mounted on the respective brackets, and the body of the machine is mounted on two drive element can be moved by a rack for carrying out the process.

The invention provides an improved design for a Shearer with a screw or the drum by the Executive body, in which the tunnel for coal transportation and handling characteristics are significantly improved.

In one of the embodiments of the Shearer with a screw or drum Executive body according to the invention two of the four legs are moving on the conveyor. The machine body the other two legs with skis based on the footwall. In addition, Shearer may have one or more of the following properties:

The machine body has holes to t the ical service in the direction of the conveyor. The drive for the feed is from the coal face.

- At the coal face Shearer with a screw or the drum of the Executive body held in a desirable position on the two guide legs slip. These guides legs actively height adjustable. Thanks to this regulation, the horizontal control lying on the side is done with a slight permutation.

The conduit shall be routed as high as possible, so that the cables could form one above the other loop.

- Roll as a government, has only one control device, mounted on the cable bridge. This cable bridge using the guide of the slide rests on the frame of the cable channel. On the frame of the machine, this cable bridge attached by a hinge.

1 schematically depicts a side view of the stope with section 10 of the lining, which in a known manner, hinged conveyor 12. Position 14 marked the machine body of the Shearer with a screw or drum Executive body, schematically shown in the figure as a single unit. Shearer with a screw or drum Executive body two legs entering the conveyor 12. At the coal face Shearer with a screw or the drum of the Executive authority sent two runners 16, reg is controlled by the height and held in its vertical position by means of the control device. Position 18 marked the cutters roll.

The power supply in the housing 14 of the machine is carried on cable bridge 20, mounted on the machine frame of the Shearer with a screw or the drum of the Executive body by a hinge 22. From stope conveyor 12 cable bridge 20 is based on frame cable tunnel 24 through the guide slide. Cable bridge 20 is connected to the device 26 management, which is managed by a Shearer with a screw or the drum by the Executive body.

Figure 2 schematically and in perspective shows the types of housing 14 of the machine, equipped with both ends of the rotary bracket 30 provided with a roller bracket. As shown in figure 2 to the right, the body 14 of the machine from the side gate has two rails 16, 16', a vertically adjustable by means of hydraulic cylinders 17, 17', respectively. In addition, the housing 14 of the machine, as shown, is equipped with sensors that determine its slope, and its movement along all three axes of space.

From the side of the conveyor 12, the housing 14 of the machine is equipped with two drive gears 32 and 34, in a known manner the setting in the rack 35. When the slider 36, provided on the drive gear 32, 34 may be made so that it is adapted to the slope conveyor 12.

According to the respective leading gear 32, 34 for submission can be fixed on the output shaft of the planetary gear. The corresponding setup is shown in figure 3, which shows two planetary gears 40, 42 on the output shafts 44, 46 are fixed respective drive gears 32, 34. Both crown gears 48, 50 of the planetary gear 40 and 42 on the one hand pinned hinge, and on the other by actuators or hydraulic cylinders 54-57 on the housing 14 of the machine.

As shown in figure 3, the planetary gear 40, is shown in figure 3 on the left, contains on the outer circumference of his crown gear 48 is diametrically opposed installed the hinges 52, 53, which has a corresponding hydraulic cylinders 54, 55, moved vertically. For the planetary gear 42 produced a similar setting, so that the crown gear 50 of the planetary gear 42 is connected to the housing 14 of the machine (left) cylinder 56 and the right hydraulic cylinder 57.

As shown in figure 3, the left hydraulic cylinder 54 of the planetary gear 40 by a line 58 connected to the left cylinder 56 of the planetary gear 42. Similarly, the right cylinder 55 of the planetary gear 40 by the line 59 is connected to the right hydraulic cylinder 57 right planetary gear 42. All hydraulic cylinders are built, the combined sensor force/path, all of the sensors (shown by dashes) lines control the population connected with the electronic device 60 controls. Using this device 60 controls can also be operated control valve 62, which may be alignment between the two lines 58 and 59.

The above device is used to compensate for errors step toothed rack 35. Separate drive segments toothed rack 35 are mounted on the trough of the conveyor 12. Because the individual elements chute movable relative to each other, there is the error of the step, as the two discontinuance legs inside the vehicle are driven simultaneously with the gears 32 and 34. When casting the rotation of the gears 32 and 34 of the torque through the corresponding crown gear is perceived in both directions, and from thence through the cylinders 54-77.

Since both cylinder perceiving torque, respectively, in one direction, hydraulically connected to each other, when the difference torques can occur alignment. Because the actuator in one direction always works for only a limited time, possible drift can be compensated for managing the distributor 62.

When designing the machine, the bracket may be straight or curved. Direct execution allows you to perform right and left bracket identical. The asymmetry is only required for suspension from a support and stop for the cylinder with the goals of the d height adjustment. The bracket is bent to facilitate the flow of coal.

If body roll cut in a downward direction, and the lever is bent upward, the coal is fed to the conveyor under the bracket. However, the site on which there is passed charcoal, small.

Many low rolls are cutting direction of the first roll from the bottom up. Due to this, these rolls have improved stability, and their boot also features a little better. At the same time, the curved bracket is not preferred.

The greater the gap between the coal face and the conveyor behind the first cutting roll appears only if the lever of the roll will be able to stay ahead of the conveyor.

Figure 4 schematically shows a side view of the Shearer with a screw or drum Executive body according to the invention, figure 4 is moving from left to right and cut into the coal K. From both end sides of the body 14 of the machine pivotally attached to the left bracket and the right bracket, respectively. In addition, on the left bracket And is the drive motor M1, and the right driving motor M2. Swath W1, mounted on left arm And moves counter-clockwise, so that it cuts the trailing side in the upward direction. Swath W2 mounted on the right arm, moves clockwise, so he cut the em footwall in the downward direction. As will still be explained in more detail with reference to figure 5-8, both of the bracket and provided with a loading shovels 70 and 72, respectively, firmly and rigidly mounted on the bracket and move the height with brackets. Thus the bracket is given additional rigidity and loading shovel provides flow cut coal on the conveyor.

As shown in figure 4, the roller W1 cut into the trailing side is clearly higher. Body roll W1, jutting out into the hanging-by-side allows felled them coal to fall straight down. However, the coal falling into a loading shovel 70, loading shovel, together with a spiral descent of the Executive body W1 mining machines can stick to the conveyor. As a result, the space above the conveyor essentially remains for the transportation of coal. Above this space is limited to only a small bridge, over which the conveyor is power and irrigation water.

Figure 5 shows a top view of the right bracket In figure 4 with the driving motor M2 mounted on the bracket, and a leading roll W2, driven in rotation of the driving motor M2. As shown in figure 5, in the top view between the driving motor M2 and the roller W2 is loading shovel 72, the task of which consists in the transfer of coal, cut roller, the direction, transverse to the direction of movement of the roll, i.e. the conveyor 12 in the direction of the arrow X. Loading shovel 72 firmly and rigidly mounted on the bracket and moves In height with bracket. Due to the fact that the loading shovel is connected to the bracket in one structural element, the bracket is given additional rigidity. Loading shovel 72 rotates the flow of the material being transported tangentially coming from the roll, 90 in the direction of the conveyor 12 and thus lifts it above the bracket C. As shown in Fig.7 and 8, the loading shovel 72, when viewed from above, has an external constraint in the form of a circle or ellipse, which may be formed as a nearly vertical wall 74. The bottom 76 of the loading shovel 72 rises up in the form of a ramp (cf. Fig), so that the flow of material being transported on the road rises so that it can act on the conveyor above the bracket Century Upper edge of the loading shovel 72 is limited so that the same swath on the way back can also be cut into the trailing side of the obviously greater height.

The bracket is bent downwards and thus is above the maximum possible aperture for the flow of coal. Thanks to this form, the bracket uses the height limitations of the conveyor. In the projection on the flow of coal he almost removed for transport, who rter, making an opening for flow of coal remains as possible.

How, in particular, shown in Fig.6, each felling W1 and W2 in a spiral installed several cutters a-d. Individual cutters in cross section is made approximately rectangular, and the circumference of the roll is oriented in a spiral 80 so that the direction of transportation of coal at the coal face arranged approximately tangentially, i.e. in the direction of the circumference of the roll, and around the conveyor 12 is approximately parallel to the axis of rotation of the roll. Thus the tangent to the spiral line on the plot near the conveyor 12 forms with the direction of the acute angle, and at the site of the coal face to the same direction - angle of approximately or exactly equal to 90, and, in particular, each spiral line 80 changes its step. Thus, the tangent to the longitudinal side cutters the cutters and located on the 6 from the edge to the right, runs approximately parallel to the axis of rotation of the roll, and the cutters d, located on 6 from the edge to the left, is an angle of about 45 to the axis of rotation. Due to this, the flow of the transported material on the loading shovel 72, the rotational motion of the roll is pushed onto the conveyor 12.
