A feeding channel 631 is provided at the bottom of the box body 63. The box body 63 moves downward by contracting the electric push rod A61. Therefore, not only can the connecting rod 13 pull the movable plate 12, so that the feed in the crushing box 1 slides from the upper surface of the movable plate 12 into the box body 63, but also because a filter screen 64 is provided in the box body 63, the feed that is not completely crushed will remain on the upper surface of the filter screen 64, and the rest will enter the mixing box 2, and then the electric push rod B67 allows the scraper 69 to push these large particles of feed to one side of the filter screen 64, which is convenient for manual cleaning and recycling, thereby preventing blockage and not wasting feed.

[0028] The crushing assembly 4 includes a motor A41 fixedly mounted on one side of the crushing box 1, a rotating shaft 42 fixedly mounted on the output end of the motor A41, and a spiral blade 43 fixedly mounted on the outer surface of the rotating shaft 42.

[0030] The outer surface of the mixing box 2 is provided with a material receiving channel 22, and the position corresponds to the material discharge channel 631. A cover plate 221 is hinged on one side of the material receiving channel 22. When the feed is crushed, the electric push rod A61 is extended to make the material discharge channel 631 leave the material receiving channel 22. At this time, the cover plate 221 can be closed to seal the mixing box 2.

[0031] An L-shaped plate 7 is provided at the bottom of the mixing box 2, and a fixing frame 71 is provided on the long side of the L-shaped plate 7.

[0032] The inner walls of the crushing box 1 and the mixing box 2 are both provided with a ceramic coating, which not only reduces material adhesion but also is not easily scratched, thereby increasing the use effect of the equipment.

[0033] Specifically, the feed raw materials to be crushed are put into the crushing box 1 from the feed hopper 11, and then the rotation of the motor A41 drives the rotating shaft 42 to rotate. Because the outer surface of a group of rotating shafts 42 is sleeved with a gear A44, the gear B45 is driven to rotate, so that the two groups of spiral blades 43 can crush the feed, and then the mixing box 2 is pushed to the bottom of the anti-blocking component 6. At this time, the box body 63 moves downward through the contraction of the electric push rod A61, so that not only can the connecting rod 13 pull the movable plate 12, so that the feed in the crushing box 1 slides from the upper surface of the movable plate 12 into the box body 63, but also the material discharge channel 631 at the bottom of the box body 63 is in contact with the material receiving channel 22 provided on the outer surface of the mixing box 2. Because the filter screen 64 is provided in the anti-blocking component 6, the feed that is not completely crushed will remain on the upper surface of the filter screen 64, and the rest will enter the mixing box 2. At this time, in the mixing box 2, the motor B 51 drives the stirring shaft 52 and drives the stirring paddle 53 to rotate, thereby mixing multiple feeds. Then, the electric push rod B67 allows the scraper 69 to push these large-grained feeds to one side of the filter screen 64, which is convenient for manual cleaning and recycling, thereby preventing blockage and not wasting feed. When the feed is crushed, the electric push rod A61 is extended to make the discharge channel 631 leave the receiving channel 22. At this time, the cover plate 221 can be closed to seal the mixing box 2. Because the bottom of the mixing box 2 is provided with an L-shaped plate 7 and a universal wheel 73, not only can the mixing box 2 be directly moved to the designated location, but also the angle of the mixing box 2 can be changed through the handle 74, so that it is convenient to mix the feed better to prevent wall sticking and to facilitate material discharge. Finally, since the inner walls of the crushing box 1 and the mixing box 2 are provided with ceramic coatings, it can not only reduce material adhesion, but also not be easily scratched, thereby increasing the use effect of the equipment.
