[0015] 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.

[0016] Please see the appendix Figures 1-5 This utility model discloses a screening device for feed production, including a mounting frame 1 and a screening box 2. The screening box 2 is equipped with a screen plate mechanism 3, an air screening mechanism 4, and a waste discharge mechanism 5, wherein: The screening box 2 is rotatably connected to the mounting frame 1. The screening box 2 is symmetrically provided with a feed inlet 23 and a screening inlet 24 on the upper and lower sides. A sealing plate 231 is detachably installed at the feed inlet 23 by bolts. The sieve plate mechanism 3 includes plates 31 symmetrically arranged in the screening box 2. The ends of the symmetrically arranged plates 31 correspond and cooperate with each other. A fixed sieve plate 36 is installed in the middle of the plates 31, and the fixed sieve plate 36 corresponds to the screening port 24. The air sieve mechanism 4 is located at the end of the plate 31 and is used to remove light impurities from the feed. The waste discharge mechanism 5 is located at the end of the plate 31 and cooperates with the air screen mechanism 4 to collect and discharge light impurities.

[0017] Please refer to the appendix. Figure 3 Appendix Figure 4 The symmetrically arranged plates 31 are mirror-staggered inside the screening box 2. The plate 31 is hollow at the fixed screen plate 36 in the middle. The hollow part in the middle of the plate 31 is movably connected to the spacer screen plate 35. The screen holes on the spacer screen plate 35 correspond to the screen holes on the fixed screen plate 36. Multiple second cylinders 34 are installed at the front end of the plate 31. The output rod of the second cylinder 34 is fixedly connected to the spacer screen plate 35.

[0018] Specifically, in the process of performing a screening operation, only the plate 31 at the top position performs the screening operation. At this time, it is necessary to ensure that the fixed screen is connected from top to bottom, while the fixed screen plate 36 on the plate 31 at the bottom position needs to be isolated from top to bottom. Therefore, by moving the isolation screen plate in the middle layer through the second cylinder 34, it is possible to control whether the fixed screen plate 36 is connected from top to bottom. That is, the two screen plates are connected when their screen holes correspond and closed when they are staggered.

[0019] Please refer to the appendix. Figure 1 Appendix Figure 3 Appendix Figure 4 The front end of the plate 31 is movably connected to a movable plate 32, which can be embedded and slid to the front end of the plate 31. The plate 31 is also equipped with a plurality of first cylinders 33, the output rods of the first cylinders 33 are fixedly connected to the movable plate 32, and the screening box 2 is equipped with an observation window 22.

[0020] Specifically, the first cylinder 33 drives the movable plate 32 to open. At this time, the feed that has completed one screening falls down into the screening box 2 through the opening at the movable plate 32. After flipping, it can be screened again.

[0021] Furthermore, a magnetic suction plate 37 is provided at the end of the plate 31. The surface of the magnetic suction plate 37 is parallel to the fixed screen plate 36. Fixed plates 371 are symmetrically installed on both sides of the magnetic suction plate 37. The fixed plates 371 extend to the outside of the screening box 2 and are connected to the connecting plate 21 fixed to the outer wall of the screening box 2 by bolts.

[0022] Specifically, the magnetic suction plate 37 adsorbs a small amount of metal impurities in the feed onto its surface. After removing the screws, the magnetic suction plate 37 can be removed from the screening box 2 to clean the impurities adsorbed on its surface.

[0023] Please refer to the appendix. Figure 5 The air screening mechanism 4 includes symmetrically mirrored air inlet channels 41. One side of the air inlet channel 41 is connected to the outside of the screening box 2 and a filter screen 42 is installed inside. The other side of the air inlet channel 41 faces the intersection of the plate body 31 and an air screening fan 43 is installed inside.

[0024] Furthermore, the waste discharge mechanism 5 includes a receiving funnel 51 symmetrically installed at the intersection of the plates 31, and a discharge nozzle 52 extending to the outside of the screening box 2 is installed at the bottom of the receiving funnel 51.

[0025] Please refer to the appendix. Figure 1 The mounting frame 1 is symmetrically equipped with a rotating table 12. The screening box 2 is rotatably connected between the rotating tables 12 through the shaft hole. The mounting frame 1 is symmetrically equipped with a power motor 11 on both sides. The output shaft of the power motor 11 is fixedly connected to the screening box 2.

[0026] Specifically, the air screen blower 43 blows the feed to remove impurities, blowing out light impurities from the feed. The blown-out impurities fall into the receiving funnel 51 and are discharged from the discharge nozzle 52.

[0027] The working principle and usage process of this utility model are as follows: After removing the sealing plate 231 at the feed inlet 23 on the top side, feed is introduced into the screening box 2. Then, the screen plate is installed at the feed inlet 23 to seal it. At this time, the power motor 11 starts and drives the screening box 2 to swing slightly left and right, causing the feed to flow along the plate 31 to the other plate 31. When the feed passes through the fixed screen plate 36, the unqualified feed falls through the screen holes on the fixed screen plate 36 and is finally discharged from the screening box 2 through the screening port 24. When the feed rolls to the magnetic suction plate 37, the magnetic suction plate 37 adsorbs a small amount of metal impurities in the feed on the surface. Then, the feed rolls down the magnetic suction plate 37 at the end of the plate 31 to the other plate. On plate 31, as the feed rolls to the front end of another plate 31, the air screen blower 43 blows the feed to remove impurities, blowing out light impurities. The blown-out impurities fall into the receiving funnel 51 and are discharged from the discharge nozzle 52. The first cylinder 33 on the other plate 31 is activated, and the first cylinder 33 drives the movable plate 32 to open. At this time, the feed on the other plate 31 falls down into the screening box 2 through the opening at the movable plate 32. After the feed has completely passed through, the first cylinder 33 is controlled to drive the movable plate 32 to close again. At this time, the power motor 11 is started to drive the screening box 2 to rotate 180°. At this time, the feed on the other plate 31 will be screened a second time along the plate 31.
