[0032] Working principle:

[0033] When the material is crushed by the crusher.

[0034] Filter screen replacement process:

[0035] When the filter screen 8 is full, first start the second motor 501 (such as Figure 2 ), at this time the rack 504 moves to the maximum distance to the right, the output shaft of the second motor 501 rotates to drive the incomplete gear 502 to rotate, thereby driving the second gear 503 to rotate, the second gear 503 drives the rack 504 to move left along the outer wall of the slide rod 506, the rack 504 moves in the sleeve 507 and continuously extrudes the clamping block 505 outward, the clamping block 505 moves outward to compress the second spring 508, the rack 504 continues to move left to drive the frame body 7 to move left, thereby driving the filter screen 8 to move left, the frame body 7 moves left into the through groove processed on the box body 2, when the incomplete gear 502 rotates one circle, the right side line of the frame body 7 coincides with the right side line of the through groove processed on the box body 2, the left filter screen 8 is ejected, and the right filter screen 8 is replaced with the left filter screen 8, and the second motor 501 is stopped, at this time the clamping groove processed on the rack 504 passes the clamping block 505 (such as Figure 7 ), the clamping block 505 is not limited by the clamping groove of the rack 504, the second spring 508 rebounds to clamp the clamping block 505 into the clamping groove of the rack 504, thereby achieving self-locking of the rack 504 to prevent the rack 504 from moving without limiting during the filtering process, thereby achieving the conveying of the frame body 7, then the left filter screen 8 is taken out by the staff, the unqualified material is poured into the box body 2 again for reprocessing, and then it can be installed again, when the right filter screen 8 is full (such as Figure 2), the second motor 501 is restarted, and the second motor 501 continues to rotate to drive the filter screen 8 to continue to move to the right by a distance of one frame 7, and the working principle is opposite to the above, so that the left side filter screen 8 is replaced by the right side filter screen 8.

[0036] The crushing process is as follows:

[0037] Start the low-speed motor 12 (such as Figure 3 ), the low-speed motor 12 has low speed and high precision, and has low noise during operation. The output shaft of the low-speed motor 12 rotates to drive the first gear 13 to rotate, thereby driving another first gear 13 to rotate. The two first gears 13 rotate in opposite directions to drive the two crushing rollers 10 to rotate in opposite directions, so that the two crushing rollers 10 can more thoroughly crush the materials. The materials to be crushed are poured into the feeding port on the box body 2, then crushed by the crushing rollers 10, and then fall onto the filter screen 8. The qualified materials continue to fall downward and fall into the collecting barrel through the slope of the inner wall of the box body 2 (such as Figure 2 ), so as to realize the crushing of the materials.

[0038] The cleaning process is as follows:

[0039] Take the left side knocking mechanism as an example (such as Figure 2 ), at this time the straight rod 306 moves to the maximum distance to the right (such as Figure 4 ), the first motor 301 is started, the output shaft of the first motor 201 rotates to drive the rotating rod 302 to rotate, the rotating rod 302 rotates to drive the cylinder 304 to move, thereby driving the rotating disc 303 to rotate. The cylinder 304 rotates to drive the connecting rod 305 to move, and the connecting rod 305 moves to drive the straight rod 306 to move leftward along the first housing 4. The straight rod 306 moves leftward to compress the first spring 307. When the cylinder 304 rotates by one hundred and eighty degrees, the straight rod 307 moves to the maximum distance to the left. When the cylinder 304 exceeds one hundred and eighty degrees while the rotating rod 302 continues to rotate, the cylinder 304 has no limit, and the straight rod 306 moves rightward quickly due to the rebound of the first spring 307, thereby driving the cylinder 304 to reset. The straight rod 306 moves rightward quickly to knock and vibrate the box body 2, so that most of the material powder adsorbed on the inner wall of the box body 2 due to static electricity can be shaken off and discharged from the discharge port. The working principle of the right side knocking mechanism 3 is opposite to the above (the left and right sides can be started synchronously or alternately knocked according to needs). The straight rod 306 moves leftward quickly, and the first motor 301 continues to rotate to drive the rotating rod 302 to continue to rotate, thereby driving the straight rod 306 to make reciprocating knocking motion, so as to clean most of the material powder adsorbed on the inner wall of the box body 2 due to static electricity. The remaining material powder can be cleaned manually by the staff, thereby reducing the workload of the staff and improving the work efficiency. After completion, the power supply of the first motor 301 is turned off.
