[0035] Specifically, when the agglomerated feed inside the collecting box 105 enters the discharge port 107, the first motor 317 operates to rotate the driving rod 316. The rotation of the driving rod 316 causes the pulley 314 on the rotating plate 315 to slide inside the sliding groove 313, so that it is convenient for the pull plate 312 to drive the arc-shaped toothed disc 307 to swing back and forth. The arc-shaped toothed disc 307 and the second toothed plate 306 are meshed with each other. The rotation of the arc-shaped toothed disc 307 causes the second toothed plate 306 to move.

[0037] As an implementation method in this embodiment, the material collection system is electrically connected to the operation control system, the material is loaded through the material collection system, and then the material crushing system is used to process the feed through the operation control system. The processed feed is subdivided by the material screening system, and finally, it is collected centrally by the material collection system.

[0038] Specifically, the crushed feed enters the screen 411, and the second motor 406 operates to rotate the second pulley 404 on the power rod 405. The rotation of the second pulley 404 drives the first pulley 402 to rotate through the transmission belt 403. The first pulley 402 is fixedly connected to the linkage rod 401, and both ends of the linkage rod 401 are fixedly connected to the disc 407. The rotation of the linkage rod 401 rotates the disc 407. The rotation of the disc 407 pushes the screen 411 to shake quickly through the linkage plate 409 on the shaft pin 408, so that the crushed feed on the screen 411 can enter the interior of the collection box 112 for centralized collection. The movement of the screen 411 causes the slider 414 to slide on the slide bar 415 through the support seat 413 on the positioning rod 412, thereby increasing the stability of the movement of the screen 411.

[0039] Working principle of the present invention: when it is necessary to push the agglomerated feed inside the aggregate box 105, the servo motor 212 is operated, and the operation of the servo motor 212 facilitates the rotation of the rotating rod 210. A gear 209 is fixedly connected to the middle position of the rotating rod 210, and the gear 209 and the first tooth plate 207 are meshed with each other. The rotation of the gear 209 drives the first tooth plate 207 to slide inside the slide rail 208, so that the first tooth plate 207 drives the cross plate 203 to move through the driven plate 204. The movement of the cross plate 203 pushes the push block 2 on the first shaft seat 201 to move inside the aggregate box 105 through the push rod 202, so that the push block 2 can push the agglomerated feed inside the aggregate box 105.

[0040] When the agglomerated feed in the collecting box 105 enters the discharge port 107, the first motor 317 operates to rotate the driving rod 316. The rotation of the driving rod 316 causes the pulley 314 on the rotating plate 315 to slide inside the sliding groove 313, so that the pull plate 312 drives the arc-shaped toothed disc 307 to swing back and forth. The arc-shaped toothed disc 307 and the second toothed plate 306 are meshed with each other. The rotation of the arc-shaped toothed disc 307 causes the second toothed plate 306 to move. The second toothed plate 306 is fixedly connected to the supporting plate 305. The movement of the second toothed plate 306 drives the frame 3 to move back and forth as a whole through the supporting plate 305, so that the driven rod 302 slides on the side plate 303, so that the scraper 301 on the frame 3 cuts the agglomerated feed.

[0041] The crushed feed enters the screen 411, and the second motor 406 operates to rotate the second pulley 404 on the power rod 405. The rotation of the second pulley 404 drives the first pulley 402 to rotate through the transmission belt 403. The first pulley 402 is fixedly connected to the linkage rod 401, and the two ends of the linkage rod 401 are fixedly connected to the disc 407. The rotation of the linkage rod 401 rotates the disc 407. The rotation of the disc 407 pushes the screen 411 to shake quickly through the linkage plate 409 on the shaft pin 408, so that the crushed feed on the screen 411 can enter the interior of the collection box 112 for centralized collection. The movement of the screen 411 causes the slider 414 to slide on the slide bar 415 through the support seat 413 on the positioning rod 412, thereby increasing the stability of the movement of the screen 411.
