A rotating motor 15 connected to the worm 14 is installed on the top of the concave seat 13. A worm wheel 16 is fixedly installed at one end of the transmission shaft 11, and the worm wheel 16 is connected to the worm 14;

[0025] During maintenance: by providing a blocking mechanism, it is only necessary to start the rotating motor 15, complete the power transmission through the worm gear 16 and worm 14, so that the transmission shaft 11 rotates, and transmits the power to the No. 1 bevel gear 10 through the two No. 2 bevel gears 12, and drives the threaded rod 8 to rotate, so that the threaded block 9 moves in the No. 2 sliding area 6, so that the sliding seat 4 moves in the maintenance area 3, and through the guidance of the No. 1 sliding area 5 and the slider 7, the movement of the sliding seat 4 is more stable, which can drive the No. 2 crushing roller 19 to move away from the No. 1 crushing roller 18, which is convenient for maintenance staff, and the worm gear 16 and worm 14 have good self-locking properties, which can ensure the stability of the transmission shaft 11. After the subsequent maintenance is completed, the sliding seat 4 can be reset by controlling the rotating motor 15 to rotate, saving time and effort;

[0026] The crushing mechanism includes a reduction motor 17 on one side of the upper surface of the frame 1, a No. 1 crushing roller 18 rotatably installed on one side of the crushing box 2, and a No. 2 crushing roller 19 rotatably installed in the sliding seat 4, and the No. 1 crushing roller 18 is engaged with the No. 2 crushing roller 19, and one end of the No. 1 crushing roller 18 and the No. 2 crushing roller 19 is rotated and extended out of the crushing box 2 and the sliding seat 4 respectively, and a transmission gear 20 is fixedly sleeved on the outside of the No. 1 crushing roller 18 and the No. 2 crushing roller 19, and the two transmission gears 20 are meshed and connected, and the output end of the reduction motor 17 is transmission-connected to the No. 1 crushing roller 18;
