Description

Technical Field

[0001] The invention relates to a non-powered crushing device and an installation structure of the device on a thin coal seam shearer. Background Art

[0002] Conventional crushing mechanisms need to be equipped with motors, reducers and other devices, which are too large in size. The body of the thin coal seam coal mining machine is thin, and the installation space and coal passing space are limited. Therefore, it is impossible to use conventional crushing mechanisms in a smaller space. Therefore, the crushing of large pieces of coal or gangue in the thin coal seam working face becomes a problem. Summary of the invention

[0003] The present invention aims to provide a non-powered crushing device for a thin coal seam coal mining machine body and an installation structure thereof, which can solve the problem of crushing large pieces of coal or gangue in a thin coal seam working face.

[0004] The main technical solutions of the present invention are:

[0005] A non-powered crushing device for a thin coal seam coal mining machine body and its mounting structure, comprising a crushing seat, a crushing pick mounting seat and a crushing pick, wherein the crushing pick is mounted on the crushing pick mounting seat, and the crushing pick mounting seat is directly welded to the crushing seat.

[0006] The crushing seat adopts a flat plate structure, the crushing pick mounting seat is located on the front of the crushing seat, a plurality of crushing seat pin holes are arranged on the back of the crushing seat, and a plurality of screw holes are arranged on the edges around the crushing seat.

[0007] The position of the pin hole of the crushing seat avoids the position where the crushing pick mounting seat is installed on the front side of the crushing seat.

[0008] A plurality of crushing pick mounting seats are fixed at intervals on the crushing seat. The crushing pick mounting seats are arranged in a plurality of rows from top to bottom, and the crushing picks in two adjacent rows are staggered with each other in the left-right direction.

[0009] The crushing pick mounting seat is arranged in two rows, upper and lower. When the front of the crushing seat is on a vertical plane, the tooth tips of the upper and lower rows of picks are inclined downward, and the angle between the center line of the upper row of picks and the front of the crushing seat is greater than the angle between the center line of the lower row of picks and the front of the crushing seat.

[0010] The included angle range between the center line of the upper row of picks and the front face of the crushing seat is 60°-75°, and the included angle range between the center line of the lower row of picks and the front face of the crushing seat is 45°-65°.

[0011] A thin coal seam coal mining machine body unpowered crushing device installation structure comprises a thin coal seam coal mining machine and the thin coal seam coal mining machine body unpowered crushing device, wherein the crushing seat is vertically installed on the left and / or right end surface of the body of the thin coal seam coal mining machine located above the coal passing space.

[0012] The thin coal seam coal mining machine has a body pin hole and a threaded hole on the left and / or right end face of the body located above the coal passing space. The crushing seat and the thin coal seam coal mining machine body are positioned and connected by installing pins in the crushing seat pin hole and the body pin hole, and are fixed by tightening screws and anti-loosening washers.

[0013] The beneficial effects of the present invention are:

[0014] Since the crushing motor, reducer and other devices are eliminated, the size of the crushing device is greatly reduced, which provides conditions for installing the crushing device on the thin coal seam coal mining machine body, thus solving the problem of crushing large pieces of coal or gangue in the thin coal seam working face.

[0015] The crushing device of the present invention does not require external power, has a simple structure, occupies a small space, is easy to install, and is suitable for the thin coal seam coal mining machine with a thin body and a narrow working space. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figure 1-3 As shown, the present invention discloses a non-powered crushing device A (referred to as a crushing device) for a thin coal seam mining machine body, comprising a crushing seat 4, a crushing pick mounting seat 5 and a crushing pick 6, wherein the crushing pick is mounted on the crushing pick mounting seat, and the crushing pick mounting seat is directly welded to the crushing seat.

[0023] The crushing seat adopts a flat plate structure, the crushing pick mounting seat is located on the front of the crushing seat, a plurality of crushing seat pin holes are arranged on the back of the crushing seat, and a plurality of screw holes are arranged on the edges around the crushing seat.

[0024] The position of the pin hole of the crushing seat is preferably away from the position where the crushing pick mounting seat is installed on the front side of the crushing seat, that is, no crushing pick mounting seat is in a front-to-back relationship with the pin hole.

[0025] A plurality of crushing pick mounting seats are fixed at intervals on the crushing seat. The crushing pick mounting seats are arranged in a plurality of rows from top to bottom, and the crushing picks in two adjacent rows are staggered in the left-right direction, that is, there are no crushing picks that are directly opposite each other up and down. This not only saves installation space for the crushing pick mounting seats, but also can cover a larger crushing area, thereby increasing the crushing area of ​​large pieces of coal or gangue.

[0026] In the embodiment shown in the attached drawings, the crushing pick mounting seat is arranged in two rows, upper and lower. When the front of the crushing seat is on a vertical plane, the tips of the picks in the upper and lower rows are inclined downward, and the angle between the center line of the upper row of picks and the front of the crushing seat is greater than the angle between the center line of the lower row of picks and the front of the crushing seat. The picks in the upper row mainly play the role of pre-crushing, that is, breaking large pieces of coal or gangue into larger blocks, and the picks in the lower row play the role of final crushing, that is, further crushing the larger blocks formed by pre-crushing, and finally achieving the purpose of allowing the crushed coal or gangue to pass smoothly under the machine body.

[0027] Furthermore, the included angle range between the center line of the upper row of picks and the front face of the crushing seat is 60°-75°, and the included angle range between the center line of the lower row of picks and the front face of the crushing seat is 45°-65°.

[0028] The crushing device of the present invention has no crushing motor and reducer, does not require external power, has a simple and refined structure, is small in size, occupies little space, and can be installed on the body of a thin coal seam coal mining machine, thereby solving the problem of crushing large pieces of coal or gangue in the thin coal seam working face.

[0029] The present invention also discloses an installation structure for an unpowered crushing device of a thin coal seam coal mining machine body, comprising a thin coal seam coal mining machine 7 and an unpowered crushing device of the thin coal seam coal mining machine body, wherein the crushing seat is vertically installed on the left and / or right end surface of the body of the thin coal seam coal mining machine located above the coal passing space 8.

[0030] The thin coal seam coal mining machine has a body pin hole and a threaded hole on the left and / or right end face of the body located above the coal passing space. The crushing seat and the thin coal seam coal mining machine body are positioned and connected by installing pins in the crushing seat pin hole and the body pin hole, and are fixed by tightening screws and anti-loosening washers.

[0031] The left and / or right end surfaces of the fuselage where the crushing seat is installed are usually planes extending vertically. The installation position of the crushing seat thereon is close to the lower edge of the fuselage.
