[0002] Feed is the general term for food for animals raised by all people. Before feed processing, various feed pretreatment equipment is first used to perform necessary pretreatment processes such as crushing, screening, impurity removal and uniform mixing of various raw materials for feed processing. Patent document with publication number CN218167677U discloses a feed processing pretreatment device, including a feed processing tank, a processing tank top cover, a feed pretreatment inner cylinder and a feed pretreatment filter assembly. The feed processing pretreatment device can screen the feed before crushing and screen out solid debris stones, thereby preventing the stones from being crushed together with the feed and improving the crushing quality of the feed. However, the device has the following defects:

[0003] Although the anti-blocking push rod, one of its structural parts, can flatten and push away the feed on the filter mesh, which is beneficial to the screening of the feed and prevents the filter mesh from being blocked, the anti-blocking push rod is vertically fixed on the rotating shaft. When workers use a rake to gather and clean the stones intercepted at various places on the upper surface of the filter mesh, the existence of the anti-blocking push rod will cause obstacles, making it inconvenient to quickly gather the stones, thereby delaying the cleaning of the filter component.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A feed preprocessor includes a counterweight base 4, a U-shaped frame 41 is vertically fixed on the top of the counterweight base 4, a center tube 3 is fixed on the side of the U-shaped frame 41, and a discharge hopper 31 is fixed at the bottom of the center tube 3. The weight of the counterweight base 4 is set relatively large. When the whole device is placed on the ground, the whole device remains stable. The bottom of the discharge hopper 31 is in an open state, and the discharge hopper 31 is convenient for gathering and discharging the feed processed inside the center tube 3 into the storage bag.

[0022] The inner cavity of the central tube 3 is fixedly provided with a screening mesh disk 5 and a matching mesh tube 8 in sequence along the vertical direction. A central motor 1 is fixedly provided on the top of the U-shaped frame 41. An anti-blocking component is provided at the output end of the central motor 1 to prevent the screening mesh disk 5 from being blocked. The anti-blocking component includes a central column 9, a locking ring 12, and an anti-blocking pushing rod 13. The top of the central column 9 is fixedly connected to the output end of the central motor 1. An external thread is provided on the outer wall of the central column 9. Receiving grooves 10 are symmetrically opened on both sides of the central column 9. The bottom of the receiving grooves 10 is symmetrically rotatably connected with anti-blocking pushing rods 13. Locking rings 12 are screwed into the tops of the two groups of anti-blocking pushing rods 13 of the central column 9. Rotating handles 11 are fixedly provided at both ends of the locking rings 12 to facilitate workers to rotate the locking rings 12 and unscrew them from the bottom of the central column 9.

[0023] A connecting column 6 is fixedly provided at the bottom of the center column 9, an eccentric roller 7 is fixedly provided at the bottom of the connecting column 6, the eccentric roller 7 extends into the inner cavity of the matching net tube 8, and mesh holes are evenly distributed at the bottom of the matching net tube 8. The outer wall of the eccentric roller 7 and the inner wall of the matching net tube 8 are both set to be frosted surfaces. A feeding hopper 2 is fixedly provided at the top edge of the center tube 3. The top of the center tube 3 is in an open state, and the bottom of the feeding hopper 2 extends to the top of the center tube 3. The bottom of the feeding hopper 2 is an inclined circular tube, which introduces the feed inside the feeding hopper 2 into the center tube 3.

[0024] The specific implementation steps and principles of the utility model are as follows:

[0025] When the whole device is working normally, the locking ring 12 is at the bottom of the center column 9, and the two sets of anti-blocking push rods 13 are pressed tightly against the top of the screening mesh plate 5. The center motor 1 is started, and the center motor 1 drives the eccentric roller 7 and the two sets of anti-blocking push rods 13 to rotate through the center column 9 and the connecting column 6. The worker feeds the feed into the center tube 3 through the feeding hopper 2, and the screening mesh plate 5 intercepts the stones in the feed, and the feed falls into the matching mesh tube 8. After being ground by the eccentric roller 7 and the matching mesh tube 8, the broken feed falls into the unloading hopper 31.

[0026] When it is necessary to clean the stones intercepted by the screening mesh plate 5, the locking ring 12 is rotated to the extreme position by human power by turning the handle 11, and finally the two sets of anti-blocking pushing rods 13 are rotated and retracted into the receiving groove 10. The worker uses a rake to gather and clean the stones on the surface of the screening mesh plate 5.

[0027] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
