The upper live pin device includes a locking pull rod 1, a fixing block 2, a connecting head 3, a main rotating shaft 4, a baffle 5, a rocker arm 6, a connecting rod 7, and a square pin shaft 8. The locking pull rod 1 passes through the fixing block 2 and is positioned on the fixing block 2 by a nut, enabling the locking pull rod 1 to rotate in place in the perforation of the fixing block 2. The fixing block 2 is fixed on the chopper 16. The inner end of the locking pull rod 1 is fixedly connected to the connecting head 3. Threads are provided inside the connecting head 3, and the locking pull rod 1 is adapted to the internal threads of the connecting head 3. When the locking pull rod 1 rotates, the position of the locking pull rod remains unchanged, and the connecting head 3 moves along the axial direction of the locking pull rod 1. The inner side of the connecting head 3 is sequentially connected to the baffle 5 and the rocker arm 6 through the main rotating shaft 4. The rocker arm 6 is arranged on the lower side of the connecting head 3. The baffle 5 is fixed to the chopper 16 by bolts. Both sides of the rocker arm 6 are connected to the connecting rod 7, and the outer end of the connecting rod 7 is connected to the square pin shaft 8. The square pin shaft 8 is inserted into the perforation of the hanging ear 17 at the upper part of the feeder 15.

[0025] The locking screw rod 1 is positioned on the fixing block 2 by the locking nut 12, and the bottom of the fixing block 2 is positioned on the chopper 16 by the positioning pin shaft 13, thereby making the fixing block 2 a direct auxiliary positioning for the rotation of the locking screw rod 1. The upper live pin device is positioned with the chopper 16 through the baffle 5 and the fixing block 2, and the connection is maintained firmly.

[0026] The lower connecting hook device connects the lower part of the feeder 15 and the chopper. The lower connecting hook device includes hooks 9, a hexagonal shaft 10, and a fixing pull rod 11. There are 2 hooks 9 in total. The two hooks 9 are respectively arranged on both sides of the feeder 15. The two hooks 9 are connected by the hexagonal shaft 10. The upper part of one of the hooks 9 extends upward and is fixedly connected to one end of the fixing pull rod 11. The other end of the fixing pull rod 11 is connected to the side wall of the chopper 16 through the locking nut 12. The hooks 9 are adapted to the round tube 18 on the lower outer wall of the feeder 15, enabling the hooks 9 to rotate around the round tube 18.

[0027] A hook 9 is connected to each of the left and right ends of a hexagonal shaft 10, so as to realize the synchronous movement of the hook 9 and lock the lower round tube 18.

[0028] Furthermore, the outer end of the locking pull rod 1 is bent into an L-shaped structure. The L-shaped structure forms a handle, which is convenient for rotating the locking pull rod 1.

[0029] Furthermore, the bottom of the fixed block 2 is fixed to the shredder 16 through a positioning pin shaft 13.

[0030] Furthermore, the main rotating shaft 4 is fixed to the connecting head 3, the main rotating shaft 4 is fixed to the rocker arm 6, the main rotating shaft 4 is rotatably connected to the baffle 5, the rocker arm 6 is rotatably connected to the connecting rod 7 through a B-type pin shaft, and the connecting rod 7 is rotatably connected to the square pin shaft 8 through a B-type pin shaft. It is convenient to drive the movement of the connecting head 3 by rotating the locking pull rod 1, and then drive the movement of the rocker arm 6, the connecting rod 7 and the square pin shaft 8, and maintain the baffle 5 fixed to the shredder 16.

[0031] Furthermore, the middle parts of the main rotating shaft 4 and the baffle 5 are connected, and the middle parts of the main rotating shaft 4 and the rocker arm 6 are connected. The rotation of the main rotating shaft 4 drives the rotation of the rocker arm 6, and then drives the synchronous rotation of the connecting rods 7 and the square pin shafts 8 on both sides.

The fixed pull rod 11 is fixedly connected to the installation plate 14. A positioning plate 21 is provided on the side wall of the shredder 16. The positioning plate 21 is arranged at the rear side of the hook 9. The rear end of the fixed pull rod 11 passes through the positioning plate 21 and is fixed to the positioning plate 21 through a locking nut 12.

[0034] The working principle of a quick disassembly and assembly device for a feeder of the present utility model is as follows: Rotate the outer end of the locking pull rod 1. The position of the locking pull rod 1 remains unchanged and it rotates in place, driving the connecting head 3 to move along the axial direction of the locking pull rod 1. The rotation of the main rotating shaft 4 drives the rotation of the rocker arm 6, the rocker arm 6 drives the movement of the connecting rods 7 on both sides, and the connecting rods 7 drive the movement of the square pin shafts 8, so that the square pin shafts 8 pass through the perforations of the hanging ears 17 on the upper part of the feeder 15 or retract to the inside of the hanging ears 17. When the square pin shafts 8 pass through the perforations of the hanging ears 17 on the upper part of the feeder 15, the feeder 15 and the shredder 16 are connected and fixed; when the square pin shafts 8 retract to the inside of the hanging ears 17, the connection between the feeder 15 and the shredder 16 is disconnected.

[0035] The working process is as follows: when the locking nut 12 is locked, the fixed pull rod 11 is lifted and locked with the chopper 16, driving the two hooks 9 to rotate synchronously around the round tube 18 of the feeder 15, locking the two round tubes 18 synchronously, so as to lock the lower part of the chopper 16 and the feeder 15. At this time, rotate the locking pull rod 1 to retract the square pin shaft 8 to the inner side of the lug 17 of the feeder 15, and rotate the feeder 15 around the lower round tube 18, so that the V-shaped part between the upper part of the feeder 15 and the chopper 16 is opened, completing the quick disassembly and assembly of the feeder 15 on the chopper 16.
