[0036] In this embodiment, the outer side of the gathering plate 12 fits tightly with the inner side of the filter tube 7. When the opening on the filter tube 7 is staggered with the feed port 5 (the opening of the filter tube 7 is blocked by the inner wall of the pretreatment box 2 to prevent the material from leaking from the opening of the filter tube 7 when the gathering plate 12 pushes the material to gather), the telescopic cylinder 3 can push the gathering plate 12 to move through the circular holes on both sides of the filter tube 7. Therefore, the circular holes on both sides of the filter tube 7 can be opened at different positions according to needs, and no specific limitation is made here.

[0038] In this embodiment, the push rod 21 can be used to make the linkage tube 11 rotate along with the second rotating body 10. The linkage tube 11 drives the first inner gear ring 18 to rotate, and the bevel gear 17 can drive the first support shaft 16 to rotate, so that the first support shaft 16 drives the cross-shaped crushing knife 14 to rotate. When the cross-shaped crushing knife 14 rotates around the support tube 4, the cross-shaped crushing knife 14 can rotate on its own, further improving the cutting effect, and then improving the crushing effect. The gathering effect of the gathering plate 12 can make the waste residues on both sides accumulate on the cross-shaped crushing knife 14 in large quantities, so that sufficient crushing can be achieved. At the same time, the self-rotating cross-shaped The crushing knife 14 can also throw away the waste residue adhering to it, thereby improving its use effect; when the first motor 13 pushes the gathering plate 12 to move, the gathering plate 12 can be used to gather the waste residues at both ends of the filter tube 7 to the middle of the filter tube 7, and at the same time, the gathering plate 12 will also push the first rotating body 9 to move toward the side of the second rotating body 10, and the first rotating body 9 will push the linkage tube 11 to move into the second rotating body 10. When the linkage tube 11 is pressed onto the stopper 34, the linkage tube 11 will drive the push rod 21 to move. The push rod 21 can charge the gas in the compression chamber 31 into the control chamber through the conduit 43 by pushing the piston plate 30 to move. The compression chamber 31 is pre-filled with gas, thereby pushing the rack 28 to move, and the rack 28 can drive the first spur gear 26 to rotate, so that the second support shaft 23 drives the I-shaped crushing knife 15 to rotate, and the I-shaped crushing knife 15 is adjusted to a vertical state. When the I-shaped crushing knife 15 is vertical, the edge of the I-shaped crushing knife 15 will contact the inner wall of the filter tube 7, which is convenient for scraping off the waste residue adhering to the filter tube 7. The scraping effect of the I-shaped crushing knife 15 is also convenient for discharging the waste residue in the filter tube 7 through the discharge port 6. The pushing effect of the first spring 22 can be used to retract the first motor 13. After that, the linkage tube 11, the first rotating body 9 and the gathering plate 12 are pushed to reset, and the gas in the control box 29 returns to the compression chamber 31, and the second spring 32 pulls the rack 28 to reset, and cooperates with the rotation effect of the torsion spring 27, so that the second support shaft 23 can drive the I-shaped crushing knife 15 to reset. Since the rotation directions of the first rotating body 9 and the second rotating body 10 are different, and the first rotating body 9 and the gathering plate 12 can move back and forth on the support tube 4, the working states of the cross-shaped crushing knife 14 and the I-shaped crushing knife 15 can also change continuously, thereby avoiding the stratification of waste slag and effectively improving the crushing effect.
