[0025] Working principle: Please refer to Figure 1-Figure 5As shown, through the crushing box 1, when the staff needs to crush the waste, first put a large amount of waste into the crushing box 1, and then use the PLC controller to start the drive motor 3, and then the drive shaft of the drive motor 3 rotates to drive the crushing roller 33 to rotate, and the two crushing rollers 33 continuously squeeze the waste to crush it, and then the crushed waste falls on the surface of the filter screen 9 for filtering, and then the crushed waste passes through the leakage holes of the filter screen 9, and the crushed waste will fall. When part of the waste is stuck in the filter screen 9, the staff will rotate the threaded column 14 at this time, and then rotate the threaded column 14 out of the thread groove 10. After that, the staff rotates the connecting block 11 to pull the filter screen 9 out of the discharge hole 4. The staff can tap the surface of the filter screen 9 at this time, and the waste stuck in the leakage hole of the filter screen 9 will roll out. When the waste inside the filter screen 9 is cleaned, the staff puts the filter screen 9 into the connecting hole 7 and the load-bearing hole 18 again, and then rotates the connecting block 11 to make the positioning hole 15 correspond to the threaded groove 10. The staff again screws the threaded column 14 into the threaded groove 10 to limit the filter screen 9, thereby achieving the effect of cleaning the waste stuck in the filter screen 9 and preventing the leakage hole of the filter screen 9 from being blocked and affecting subsequent filtration.

[0026] Through the provided connecting plate 21, when the staff is filtering the crushed waste, after the waste falls onto the surface of the filter screen 9, the staff uses the PLC controller to start the servo motor 28, and then the driving shaft of the servo motor 28 rotates to drive the connecting plate 26 to rotate, and then drives the connecting plate 26 and the stabilizing column 24 to rotate. As the stabilizing column 24 continues to make a circular motion, it drives the connecting plate 21 to be continuously pulled, thereby driving the filter screen 9 and the positioning plate 8 to move continuously, and then the filter screen 9 shakes, and the waste on the surface of the filter screen 9 moves continuously to drive the waste to be filtered. At the same time, the larger waste that has not been filtered keeps rolling and then falls from the discharge hole 4, so as to facilitate the filtering of the crushed waste.
