Abstract
Description
Technical Field
[0001] This utility model relates to the field of feed processing technology, specifically to a feed processing sorting sieve with multi-stage screening. Background Technology
[0002] Feed is a general term for the food of animals raised by all people. In a narrower sense, feed mainly refers to the food of animals raised in agriculture or animal husbandry.
[0003] When screening feed, the feed is usually put into a screening box. The vibration of the screening box causes the feed to pass through the screening screen, thus achieving the screening of the feed. However, when adding feed, a large amount of feed is easily piled up at the screening screen, resulting in low screening efficiency. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model uses a first motor to drive a lead screw, which slides along a sliding rod via a lug at the other end, causing the moving box to move back and forth. The feed is placed at the feed pipe, and the first rotating shaft disperses the feed through a stirring rod, causing the feed to fall into the screen. The feed then falls from the screen to both sides and into the screening screen at the bottom of the screening box. Because the moving box moves back and forth, the feed can be dispersed and screened, preventing the feed from accumulating at the screen and improving the feed screening efficiency.
[0013] 2. This utility model also uses a third rotating shaft to rotate, and the spring pulls the limiting plate to drive the retracting rod to move, thereby increasing the pressure between the striking head and the strainer. The striking head strikes the strainer, which can vibrate the strainer to facilitate the feed falling and prevent the feed from adhering to the point where it falls into the strainer.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 This utility model provides a technical solution: a feed processing sorting screen with multi-stage screening, including a screening box 1. Two sets of fixing plates 2 are fixedly welded to the upper inner side of the screening box 1. A sliding rod 3 is fixedly welded between the rear fixing plate 2 and the screening box 1. A rear lug 8 is slidably installed on the outer side of the sliding rod 3. A lead screw 4 is rotatably connected between the front fixing plate 2 and the screening box 1. The lead screw 4 is threadedly installed on the outer side of the front lug 8. A first motor 5 is installed on the outer flange of the screening box 1. The first motor 5 is connected to the lead screw 4 via a coupling. A movable box 6 is fixedly welded between the front and rear lugs 8. An inlet valve is fixedly welded to the upper part of the movable box 6. Feed pipe 7 has mounting plates 9 fixedly welded to its upper and lower sides. A first rotating shaft 10 is rotatably connected between the upper and lower mounting plates 9. Several sets of stirring rods 11 are fixedly welded to the outside of the first rotating shaft 10. A strainer 22 is fixedly welded to the lower part of the moving box 6. The first motor 5 drives the lead screw 4, which slides along the sliding rod 3 through the other end lug 8, causing the moving box 6 to move back and forth, feeding the feed into the feed pipe 7. The first rotating shaft 10 disperses the feed through the stirring rods 11, causing the feed to fall into the strainer 22 and into the screening screen at the bottom of the screening box 1. Due to the back and forth movement of the moving box 6, the feed can be dispersed and screened.
[0021] The strainer 22 is designed with a high center and low sides to facilitate feed scattering to both sides, allowing the feed to easily fall to the front and rear of the screening box 1. Inside the screening box 1, two sets of third rotating shafts 15 are rotatably installed on both sides. Several sets of receiving and releasing cylinders 16 are fixedly welded inside the third rotating shafts 15. Receiving and releasing rods 18 are slidably installed inside the receiving and releasing cylinders 16, and striking heads 21 are fixedly welded to the outside of the receiving and releasing rods 18. When the third rotating shafts 15 rotate, the receiving and releasing rods 18 inside the receiving and releasing cylinders 16 strike the strainer 22 through the striking heads 21, thus... The mesh 22 vibrates to facilitate feed falling; a sliding plate 17 is fixedly welded to one side of the take-up rod 18, and limiting plates 19 are fixedly welded to both sides of the take-up cylinder 16 to prevent the sliding plate 17 from detaching from the take-up cylinder 16. A spring 20 is fixedly welded between the limiting plate 19 and the sliding plate 17. The spring 20 is sleeved on the outside of the take-up rod 18. The spring 20 pulls the limiting plate 19, causing the take-up rod 18 to move, increasing the pressure between the striking head 21 and the mesh 22; a second motor 23 is installed on the outer flange of the moving box 6. The second motor 23 is connected to a coupling of a third rotating shaft 15 on one side. An upper bevel gear 12 is fixedly welded to the lower part of the first rotating shaft 10. A lower bevel gear 13 is meshed with the lower part of the upper bevel gear 12. A second rotating shaft 14 is fixedly welded to the tail of the lower bevel gear 13. The other ends of the third rotating shaft 15 and the second rotating shaft 14 penetrate to the outside of the movable box 6. A staggered transmission belt 24 is sleeved on the outer side of the other ends of the third rotating shaft 15 and the second rotating shaft 14. The second motor 23 drives the third rotating shaft 15 on one side. The third rotating shaft 15 drives the second rotating shaft 14 to rotate through the transmission belt 24. The second rotating shaft 14 drives the third rotating shaft 15 on the other side to rotate through the transmission belt 24. The second rotating shaft 14 drives the upper bevel gear 12 to rotate through the lower bevel gear 13, thereby causing the first rotating shaft 10 to rotate and providing power to the equipment. Several sets of isolation plates 25 are fixedly welded to the outer side of the other ends of the third rotating shaft 15 and the second rotating shaft 14. The isolation plates 25 are set on both sides of the transmission belt 24 to prevent the transmission belt 24 from slipping.
[0022] Working principle: In use, the first motor 5 drives the lead screw 4, which slides along the sliding rod 3 via the other end lug 8, causing the moving box 6 to move back and forth, dispensing feed into the feed pipe 7. The second motor 23 drives a third rotating shaft 15 on one side, which in turn drives a second rotating shaft 14 via a transmission belt 24. The second rotating shaft 14, in turn, drives the third rotating shaft 15 on the other side via the transmission belt 24. The second rotating shaft 14, through a lower bevel gear 13, drives an upper bevel gear 12 to rotate, thereby causing the first rotating shaft 6 to move back and forth. The rotating shaft 10 rotates, and the first rotating shaft 10 disperses the feed through the stirring rod 11, causing the feed to fall into the strainer 22. The feed is scattered to both sides from the strainer 22, and falls into the screening screen at the bottom of the screening box 1. As the moving box 6 moves back and forth, the feed can be dispersed and screened. The third rotating shaft 15 rotates, and the spring 20 pulls the limiting plate 19, which drives the retracting rod 18 to move, increasing the pressure between the striking head 21 and the strainer 22. The striking head 21 strikes the strainer 22, which can vibrate the strainer 22 to facilitate the feed falling.
