[0013] (1) A connecting shaft is provided inside the crushing box. A connecting rod mechanism for controlling the movement of the crushing knife is provided inside the connecting shaft. The movement of the crushing knife can adjust the distance between the two crushing knives. According to the needs of the growth size of chicks, the feed raw materials can be coarsely or finely crushed. The connecting rod mechanism is adjusted through the movable rod. When adjusting, only the threaded rod needs to be rotated to control the equidistant movement of the four crushing knives at the same time. When the feed raw materials need to be coarsely crushed after being crushed, the knife distance can be increased. When the feed needs to be finely crushed after being crushed, the knife distance can be reduced. Groove teeth are provided between the two crushing knives. The groove teeth are meshed with each other to complete self-cleaning between the tools and avoid feed jamming in the tooth grooves.

[0014] (2) The crushing knife is fixed to the connecting shaft through the fixing plate. The U shape of the fixing plate can better fix the crushing knife to prevent it from loosening during high-speed rotation. Fixing screws are provided on the fixing plate. The fixing screws can be used to disassemble the crushing knife by tightening or loosening. When the blade of the crushing knife is worn or damaged after long-term use and needs to be replaced, it can be quickly replaced without replacing the entire connecting shaft, causing unnecessary waste.

Specific implementation manners

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , a technical solution provided by the present utility model:

[0023] Embodiment 1:

[0024] In this embodiment, a crushing device for chicken feed processing includes a support plate 7. A crushing box 6 is provided at the top of the support plate 7. A connecting shaft 5 is arranged side by side between the front and back inner walls of the crushing box 6. A threaded rod 14 is rotatably arranged on the front side of the inner wall of the connecting shaft 5. The threaded rod 14 is provided with four symmetrically arranged threads with opposite spiral directions. The front side of the threaded rod 14 penetrates through the connecting shaft 5 and extends to the outside of the connecting shaft 5. A control block 13 is arranged on the front side of the threaded rod 14.

[0025] In this embodiment, the control block 13 can be engaged and clamped between the connecting shaft 5 and the threaded rod 14, and the control block 13 is matched with the connecting shaft 5 through magnetic attraction.

[0026] In this embodiment, a number of movable rings 16 are provided on the threaded rod 14. Two movable rings 16 form a group. When the movable rings 16 are driven by the rotation of the threaded rod 14, they will move towards each other. A number of rotating shafts 15 are equidistantly arranged in a circumferential array around the movable rings 16.

[0027] In this embodiment, a first movable rod 12 is rotatably provided at the top of the rotating shaft 15, and a second movable rod 18 is rotatably provided at the top of the other rotating shaft 15. The tops of the first movable rod 12 and the second movable rod 18 are both rotatably connected to the rotating seat 17. The first movable rod 12 and the second movable rod 18 form a V shape after combination.

[0028] In this embodiment, a fixing plate 11 is provided at the top of the rotating seat 17. The fixing plate 11 is U-shaped. A crushing knife 9 is provided inside the fixing plate 11. A number of groove teeth are provided on the crushing knife 9. A number of fixing screws 10 penetrate through the fixing plate 11 in a straight line.

[0029] In this embodiment, a bracket 3 is provided at the bottom of the support plate 7, a base 4 is provided at the bottom of the bracket 3, and a motor 8 is provided on one side of the top of the base 4.

[0030] In this embodiment, a linkage wheel 1 is provided on each side of the front of the crushing box 6. The two linkage wheels 1 are meshed with each other. A pulley group 2 is provided on the front of one of the linkage wheels 1. The pulley group 2 is fixedly connected to the output shaft of the motor 8.

[0031] Working principle: When in use, first adjust the knife spacing between the two crushing knives 9 according to actual needs. If the raw materials to be crushed are coarser, the knife spacing can be set larger; otherwise, it can be adjusted smaller. When adjusting, pull the control block 13 outwards for a certain distance so that it leaves the groove in the connecting shaft 5. After leaving, rotate to control the threaded rod 14 to rotate with the rotation connection point with the connecting shaft 5 as the center. The rotation of the threaded rod 14 can control the two movable rings 16 in a group to move towards or away from each other. When the two movable rings 16 move, they will drive the first movable rod 12 and the second movable rod 18 to move with the rotation connection point with the rotating seat 17 as the center. When the two move towards each other, they will push the rotating seat 17 to one side. The rotating seat 17 will drive the fixing plate 11 to move, and the fixing plate 11 will drive the crushing knife 9 to move. After adjusting the spacing, the motor 8 can be started. The motor 8 drives the pulley group 2 to rotate. The pulley group 2 drives the two linkage wheels 1 to mesh and rotate with each other. The linkage wheel 1 will drive the connecting shaft 5 to rotate, and the two groups of crushing knives 9 will crush the feed raw materials. When a blade of the crushing knife 9 is damaged after long-term use, the crushing knife 9 can be replaced individually by loosening and tightening the fixing screws 10, which is more convenient and faster than replacing the whole unit.

[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
