Through the arrangement of the hinge 3, the limit baffle 4 and the handle 5, the lower shell 2 of the device can be effectively rotated and removed from the top of the upper shell 1 of the device.

[0019] A motor 6 is installed on one side of the upper shell 1 of the device. Two crushing rollers 7 are rotatably installed inside the upper shell 1 of the device. Tooth plates 8 for easy disassembly and assembly are installed in an annular manner and at equal distances on the surfaces of the two crushing rollers 7. The tooth plates 8 are arc-shaped structures. The output end of the motor 6 is fixedly connected to the axis of one of the crushing rollers 7, and one end of the axis of the two crushing rollers 7 extends to the outside of the upper shell 1 of the device and is fixedly installed with a first gear 9. The two first gears 9 are meshed and connected. A guide hopper 10 is fixedly installed inside the lower shell 2 of the device. The guide hopper 10 is located between the tops of the two crushing rollers 7; the two crushing rollers 7 are relatively rotated by starting the motor 6 and through the two first gears 9. The relative rotation of the two crushing rollers 7 drives the tooth plates 8 on their surfaces to rotate, and then the waste residue is added into the inside of the guide hopper 10 so that the waste residue falls between the two rotating crushing rollers 7, so that the tooth plates 8 crush the waste residue.

[0020] The surfaces of the two crushing rollers 7 are both provided with arc-shaped mounting grooves 11 at equal intervals in an annular manner, the tooth plate 8 is movably installed inside the arc-shaped mounting groove 11, the inner arc surface of the tooth plate 8 is fixedly provided with a clamping strip, the bottom of the arc-shaped mounting groove 11 is provided with a clamping slot matching the clamping strip, and one side of the clamping strip and the clamping slot are both inclined structures, so that the tooth plate 8 can be stably installed inside the arc-shaped mounting groove 11, a circular inner cavity 12 is provided in the middle of the two crushing rollers 7, an L-shaped sliding mounting groove 13 connected to the circular inner cavity 12 is provided in the middle of the bottom of the clamping groove, an insert block 14 is slidably installed inside the L-shaped sliding mounting groove 13, a slot 15 is provided in the middle of the bottom of the clamping strip, the upper part of the insert block 14 is movably inserted into the inside of the slot 15, and the insert block 14 is located on one side of the lower part of the L-shaped sliding mounting groove 13 The first rack 16 is fixedly installed, which can effectively limit and fix the tooth plate 8, so as to maintain the firmness of the installation of the tooth plate 8. The lower part of the L-shaped sliding installation groove 13 is rotatably connected with the second gear 17 meshing with the first rack 16. The middle part of the circular inner cavity 12 is rotatably connected with a threaded shaft 18. The surface of the threaded shaft 18 is threadedly connected with a moving sleeve 19. The surface of the moving sleeve 19 is annularly and equidistantly fixed with a second rack 20 meshing with the second gear 17. The number of the second racks 20 is the same as the number of the second gears 17. One end of the two threaded shafts 18 respectively penetrates the two crushing rollers 7 and extends to the outside of one side of the two first gears 9, and one end of the two threaded shafts 18 is fixedly installed with an adjusting wheel 21, so that it can be effectively adjusted.

[0021] When it is necessary to disassemble the toothed plate 8, open the lower housing 2 of the device, and rotate the adjusting wheel 21 to rotate the threaded shaft 18. The rotation of the threaded shaft 18 will cause the movable sleeve 19 to drive the second rack 20 to move. The movement of the second rack 20 will drive the second gear 17 to rotate. The rotation of the second gear 17 will drive the first rack 16 to move. The movement of the first rack 16 will drive the plug block 14 to move, so that the upper part of the plug block 14 moves from the inside of the slot 15 to the inside of the L-shaped sliding mounting groove 13. At this time, push the toothed plate 8 and the clamping strip to move the toothed plate 8 and the clamping strip out of the arc-shaped mounting groove 11 and the inside of the clamping groove for disassembly; when installing, just perform the above steps in reverse.

[0022] A socket 22 is provided on one side of the two first gears 9, and a cross pin 23 is movably inserted on the surface of the two adjusting wheels 21. One end of the cross pin 23 is movably inserted in the inside of the socket 22, and a spring 24 is sleeved in the middle of the cross pin 23. The two ends of the spring 24 are fixedly connected to the cross pin 23 and the adjusting wheel 21 respectively, and the other end of the cross pin 23 is fixedly connected to a pull ring 25, so as to effectively ensure the stable shape of the adjusting wheel 21.

[0023] By inserting the cross pin 23 into the inside of the socket 22, it can be ensured that the adjusting wheel 21 will not rotate automatically when the first gear 9 rotates; when the adjusting wheel 21 needs to be rotated, the cross pin 23 is pulled by the pull ring 25 to compress the spring 24, so that one end of the cross pin 23 is withdrawn from the inside of the socket 22, and then the adjusting wheel 21 can be rotated.

[0024] In addition, the crushing device has a simple structural design, is easy to use and operate, and its performance can meet the requirements of coal chemical waste slag treatment.
