The linkage mechanism 26 includes: a rack 261, fixedly connected to the outer wall of the connecting plate 23; a fixed rod 262, rotatably connected to the inner wall of the crushing box 11; a pulley 263, arranged on the rotating shaft 21 and the fixed rod 262, and the rotating shaft 21 and the fixed rod 262 are connected by the pulley 263; a gear 264, fixedly connected to the left end of the fixed rod 262, and the gear 264 is meshed with the rack 261. A connecting mechanism 27 is provided on the connecting plate 23 and the screen 24, and the connecting mechanism 27 includes: a connecting block 1 271, symmetrically arranged on the outer wall of the screen 24; a connecting block 272, symmetrically arranged on the outer wall of the connecting plate 23, and corresponding screw holes are provided on the connecting block 1 271 and the connecting block 2 272; a bolt 273 is threadedly connected to the screw holes provided on the connecting block 1 271 and the connecting block 2 272; the crushing box 11 is a segmented design, and a group of the connecting mechanism 27 is also provided between the crushing boxes 11.

[0051] When in use, the staff puts the grass into the feed pipe 12, the grass enters the screen 24 through the feed pipe 12, and the motor 22 is started. The motor 22 drives the rotating shaft 21 and the crushing knife 25 to rotate, and the crushing knife 25 crushes the grass in the screen 24. The grass particles crushed to a suitable size pass through the screen 24 and fall to the bottom of the crushing box 11. The grass that is not completely crushed and has larger particles remains in the screen 24 and continues to be crushed by the crushing knife 25 until the grass particles reach a suitable size and can be discharged from the discharge port 13. Therefore, the grass is uniform in size after being crushed, which is convenient for cattle and sheep to eat. At the same time, when the rotating shaft 21 rotates, the linkage mechanism 26 links the screen 24 and the crushing knife 25 to rotate in the opposite direction, and the grass in the screen 24 is turned over, thereby improving the crushing efficiency of the crushing knife 25: when the rotating shaft 21 rotates, the fixed rod 262 connected to the rotating shaft 21 through the pulley 263 drives the gear 264 to rotate in the same direction, and the rack 261 meshing at the bottom of the gear 264 drives the connecting plate 23 and the screen 24 to rotate in the opposite direction, and the grass in the screen 24 is turned over, which is convenient for the crushing knife 25 to evenly crush the grass, avoiding the accumulation of grass on the inner side of the screen 24, which is inconvenient for the crushing knife 25 to contact, thereby affecting the grass crushing efficiency. The screen 24 can be replaced through the connecting mechanism 27: the staff can unscrew the bolts 273 on the outside of the crushing box 11 to release the connection between the connecting block 1 271 and the connecting block 2 272, so that the crushing box 11 can be separated, and the feed pipe 12 can pull out the screen 24, at which time the internal screen 24 is exposed, which is convenient for the staff to unscrew the bolts 273 on the screen 24 to separate the screen 24 and the connecting block 1 271 and the connecting block 2 272 on the connecting plate 23, and the screen 24 can be removed, which is convenient for the staff to clean, or replace the screen 24 with different meshes, so as to control the particle size of the grass after crushing. After the cleaning and replacement of the screen 24 is completed, the bolts 273 are screwed to connect the screen 24 to the connecting plate 23, and the feed pipe 12 is inserted into the screen 24, and the two-stage crushing box 11 is closed, which is convenient for the next crushing.

[0055] When the screen 24 rotates, the guide plate 241 guides the grass inside the screen 24 to the side of the crushing knife 25, which is convenient for the grass to contact the crushing knife 25, and improves the crushing efficiency of the crushing knife 25. The cleaning component 3 cleans the screen holes when the screen 24 rotates to prevent the screen holes from being blocked by grass particles and affecting the normal feeding speed of the grass particles: when the screen 24 rotates, the protrusion 33 contacts the screen holes on the screen 24, and the protrusion 33 pushes the grass particles stuck in the screen holes into the screen 24, and is crushed again by the crushing knife 25. When the screen 24 moves, the protrusion 33 can be extended and retracted by the elastic force of the spring 34, so as to be convenient for detaching from the current screen hole and entering the next screen hole. The telescopic rod 32 can rotate to facilitate the movement of the protrusion 33. At the same time, the telescopic rod 32 guides the extension and retraction of the spring 34 to prevent the spring 34 from exceeding the elastic limit when extending and retracting, thereby affecting the normal use of the protrusion 33. The telescopic shell 35 is telescopically extended and retracted along with the movement of the protrusion 33 , and the telescopic shell 35 shields the spring 34 and the telescopic rod 32 , so as to prevent the grass particles from adhering to the vicinity of the spring 34 and the telescopic rod 32 and affecting their normal use.
