[0002] Feed is food used to feed animals, usually including grains, beans, oil, protein sources (such as fish meal, bone meal, soybean meal, etc.) and vitamins, minerals and other nutrients. The feed particles that have been crushed and screened are more uniform in size, which is conducive to the uniform mixing of various ingredients in the feed. This helps to ensure that animals can ingest various nutrients when eating feed, avoiding the situation of excessive or insufficient amounts of some nutrients. Therefore, a feed production feed crushing and screening device is needed.

[0003] When an existing feed production feed crushing and screening device is in use, the crushing motor is set to drive the crushing knife to rotate at high speed to perform preliminary crushing of the feed, and then the crushed feed is screened through the screen. However, this method cannot drive the screen plate to shake when in use, and the screening effect is poor. If the screen plate cannot be effectively shaken, the residence time of the feed in the screen hole will increase, and the screening effect is poor, resulting in failure to effectively separate the target particles, thereby affecting the quality and uniformity of the feed, and failing to effectively separate impurities and particles that do not meet the specifications in the feed, thereby affecting the quality of the feed.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 , Figure 3 and Figure 5 The utility model provides an embodiment: a feed production feed crushing and screening device, including a screening box 1, a backing plate 4 is fixedly connected to the left part of the screening box 1, a motor 5 is fixedly connected to the upper part of the backing plate 4, a rotating shaft 13 is fixedly connected to the output end of the motor 5, a cam 14 is fixedly connected to the outside of the rotating shaft 13, a movable block 15 is arranged on the upper part of the cam 14, a screen plate 19 is fixedly connected to the right part of the movable block 15, fixed plates 16 are fixedly connected to both sides of the left part of the screening box 1, and limiting columns 17 are fixedly connected to the opposite sides of the two fixed plates 16, the movable block 15 is slidably connected to the outside of the limiting column 17, and a buffer spring 18 is sleeved on the outside of the limiting column 17, one end of the buffer spring 18 is fixedly connected to the movable block 15, and the other end of the buffer spring 18 is fixedly connected to the fixed plate 16.

[0025] The motor 5 drives the rotating shaft 13. When the rotating shaft 13 rotates, the cam 14 also rotates. The cam 14 can drive the movable block 15 to slide outside the limiting column 17 during the rotation process. This sliding movement not only enables the movable block 15 to move according to a predetermined trajectory, but also can squeeze or stretch the buffer spring 18 during the sliding process. The buffer spring 18 is an important buffer element in the screening system. Its function is to absorb the impact force and vibration generated by the movable block 15 during the movement process, thereby ensuring the stability and continuity of the screening process. When the movable block 15 slides outside the limiting column 17, the buffer spring 18 will be squeezed or stretched, causing it to produce corresponding deformation. This deformation can not only effectively absorb impact force and vibration, but also provide necessary support and guidance for the movement of the movable block 15. The movement of the movable block 15 eventually drives the screen plate 19 to shake up and down. When the screen plate 19 shakes up and down, under the combined action of gravity and the shaking force of the screen plate 19, the qualified feed particles pass through the sieve holes and fall into the collection area below, while larger impurities and lumps remain on the screen plate 19.

[0026] Reference Figure 3 and Figure 4 A hydraulic cylinder 20 is fixedly connected to the inner bottom of the screening box 1, and a mounting plate 21 is fixedly connected to the output end of the hydraulic cylinder 20. A cleaning brush 22 is fixedly connected to the upper part of the mounting plate 21. Limiting components are fixedly connected to both sides of the bottom of the mounting plate 21. The limiting components include a moving rod 24, which is slidably connected to the inside of a fixed rod 23. A compression spring 25 is fixedly connected to the inside of the fixed rod 23, and the other end of the compression spring 25 is fixedly connected to the bottom of the moving rod 24. The fixed rod 23 is fixedly connected to the inner bottom of the screening box 1, the sieve plate 19 is slidably connected to the inside of the screening box 1, the mounting plate 21 is slidably connected to the inside of the screening box 1, and the sieve plate 19 is arranged on the upper part of the cleaning brush 22.

[0027] After the screen plate 19 has screened the feed for a period of time, the hydraulic cylinder 20 is started, and the output end of the hydraulic cylinder 20 is closely connected to the mounting plate 21. As the hydraulic cylinder 20 is started, its output end pushes the mounting plate 21 to move upward. During the upward movement of the mounting plate 21, the moving rod 24 fixed thereon is driven to slide inside the fixed rod 23. This design not only ensures the stable movement of the mounting plate 21, but also makes the entire cleaning process more stable and reliable. During the sliding process, the moving rod 24 stretches the compression spring 25, and the compression spring 25 The elastic force makes the moving rod 24 have a certain buffering effect during the movement, thereby reducing the impact force on the screen plate 19 and protecting the service life of the screen plate 19. As the mounting plate 21 moves upward, the cleaning brush 22 also moves upward. The bristles of the cleaning brush 22 are soft and have a certain hardness, and can be easily inserted into the sieve holes of the sieve plate 19. When the cleaning brush 22 is inserted into the sieve holes, the blockages in the sieve holes are cleaned through the friction and scraping action of the bristles. This cleaning process can effectively remove impurities and blockages in the sieve holes and keep the sieve holes unobstructed.

[0028] Reference Figure 2 and Figure 3 The outside of the rotating shaft 13 is fixedly connected with a driving pulley 6, and the driving pulley 6 is connected with a driven pulley 8 through a belt 7. The inside of the driven pulley 8 is fixedly connected with a rotating rod 9, and the other end of the rotating rod 9 is fixedly connected with a driving gear 10. The rear of the driving gear 10 is meshed and connected with a driven gear 11. The insides of the driving gear 10 and the driven gear 11 are fixedly connected with a crushing roller 12. The upper part of the screening box 1 is fixedly connected with a crushing box 2, and the crushing roller 12 is rotatably connected to the inside of the crushing box 2. A feed hopper 3 is provided on the upper part of the crushing box 2, and a discharge hopper 26 is provided on the right part of the screening box 1.

[0029] Feed is added into the crushing box 2 through the feed hopper 3, and the motor 5 is started. The output end of the motor 5 is connected to the rotating shaft 13. When the motor 5 is started, it drives the rotating shaft 13 to start rotating, and transmits power through a series of pulleys and gears, so that the crushing roller 12 can rotate. With the rotation of the rotating shaft 13, the driving pulley 6 also starts to rotate. The driving pulley 6 is connected to the driven pulley 8 through the belt 7. When the driving pulley 6 rotates, it drives the driven pulley 8 to rotate together through the belt 7. When the driven pulley 8 rotates, it drives the rotating rod 9 and the driving gear 10 to rotate together. The rotation of the driving gear 10 drives the driven gear 11 meshed with it to rotate together. When the driving gear 10 and the driven gear 11 rotate, they drive the crushing roller 12 to start rotating. During the rotation process, the crushing roller 12 crushes the feed and breaks it into particles of a required size.

[0030] Working principle: First, feed is added into the crushing box 2 through the feed hopper 3, and the motor 5 is started. The output end of the motor 5 drives the rotating shaft 13 to rotate. The rotating shaft 13 drives the driving pulley 6 to rotate. The driving pulley 6 drives the driven pulley 8 connected by the belt 7 to rotate. The driven pulley 8 drives the rotating rod 9 and the driving gear 10 to rotate. The driving gear 10 drives the meshing driven gear 11 to rotate. When the driving gear 10 and the driven gear 11 rotate, the crushing roller 12 is driven to rotate. The crushed feed is transported to the inside of the screening box 1. The rotating shaft 13 drives the cam 14 to rotate while the cam 14 rotates. The rotation of the cam 14 drives the movable block 15 to slide on the outside of the limit column 17. When the movable block 15 slides, it squeezes or stretches the buffer spring 18. The movable block 15 moves and drives the screen plate 19 to shake up and down to screen the feed. After screening, qualified feed is discharged outward through the discharge hopper 26, thereby effectively driving the screen plate to shake and screen the feed, and impurities and lumps in the feed can be screened out, which is beneficial to the animal's feeding and digestion and absorption, reducing the wear and damage of subsequent processing equipment, and extending the service life of the equipment. After the screen plate 19 screens the feed, the hydraulic cylinder 20 is started, and the output end of the hydraulic cylinder 20 pushes the mounting plate 21 to move upward. When the mounting plate 21 moves, it drives the moving rod 24 to slide inside the fixed rod 23. When the moving rod 24 moves, the compression spring 25 is stretched. The movement of the mounting plate 21 drives the cleaning brush 22 to move upward, so that the cleaning brush 22 is inserted into the sieve hole of the screen plate 19, and the screen plate 19 is cleaned by the cleaning brush 22, thereby effectively cleaning the screen plate 19, keeping the sieve hole unobstructed, ensuring the smooth passage of the feed, and improving the screening efficiency.
