[0002] As the main food source for livestock, feed occupies an important position in the breeding industry. Different varieties of feed enrich the dietary structure of livestock and lay a solid foundation for the healthy growth of livestock.

[0003] In order to improve the digestibility of feed for livestock, it is necessary to grind the feed into fine particles. However, the existing feed grinders may not grind the feed thoroughly during the grinding process. The feed that is not completely ground will be mixed with the qualified feed. In this case, it is usually necessary to manually screen and separate these miscellaneous materials. The screening and separation process is relatively cumbersome and will consume a certain amount of time and labor costs. Based on this problem, the utility model proposes a solution.

It is worth noting that the end of the guide plate 4 away from the inner wall of the crushing box 1 is close to the discharge port 8, ensuring that the guide plate 4 can guide the feed to a position close to the discharge port 8. A first mechanism groove 10 is opened on the side wall of the crushing box 1, a driving gear 20 is rotatably connected to the inner wall of the first mechanism groove 10, a driven gear 21 is rotatably connected to the inner wall of the first mechanism groove 10, the driving gear 20 and the driven gear 21 are meshed, a driving motor 2 is fixedly connected to the side wall of the crushing box 1, the driving gear 20 is coaxially fixedly connected to the output shaft of the driving motor 2, the driving gear 20 is coaxially fixedly connected to the first crushing wheel 5, and the driven gear 21 is coaxially fixedly connected to the second crushing wheel 6.

[0023] A limit groove 11 is provided on the side wall of the crushing box 1, and the screen 3 is slidably connected in the limit groove 11. It should be noted that the angle between the screen 3 and the horizontal plane needs to be controlled between 30° and 40° to ensure that the feed that has not been completely crushed can slide smoothly from the screen 3 during the up and down reciprocating motion of the screen 3. A driving device for driving the screen 3 to move up and down is installed in the first mechanism groove 10, and the driving device includes a crank 17 rotatably connected to the side wall of the driven gear 21 at an eccentric position, and the end of the crank 17 away from the driven gear 21 is rotatably connected to a connecting rod 18, and the side wall of the connecting rod 18 is fixedly connected to the side wall of the screen 3.

[0024] The inner bottom of the crushing box 1 is slidably connected with a push plate 16, the height of the push plate 16 is equal to the distance between the inner bottom and the inner top of the discharge port 8, and the length of the push plate 16 is greater than the distance between the two inner walls of the discharge port 8.

Driven by the driven gear 21, the crank 17 will rotate, and the crank 17 will drive the connecting rod 18 and the rectangular block 19 to move up and down during the rotation, and then drive the screen 3 to reciprocate up and down. Since the screen has a certain inclination angle relative to the horizontal plane, the large particles of feed that have not passed through the screen will slide off the screen and be separated, and discharged through the additional discharge port 9, while the small particles of feed that have passed through the screen 3 will fall to the bottom of the crushing box 1 along the guide plate 4. During the up and down reciprocating motion of the screen 3, the first rack 13 will be driven to reciprocate up and down, and the first rack 13 will mesh with the transmission gear 14 during the motion, and the transmission gear 14 will mesh with the second rack 15 during the rotation, thereby driving the second rack 15 to reciprocate in the horizontal direction, and finally the second rack 15 will drive the push plate 16 to repeatedly push the feed at the bottom of the crushing box 1 out of the discharge port 8.
