The advantage of the utility model is that after the hot air diffuses, it passes through the screen to blow hot air to the feed on the top of the screen, and the hot air takes away moisture and accumulates in the protruding top cover. The outlet fan on the top of the outlet pipe is started, and the humid hot air is extracted when the hot air gathers more. After the hot air is heated by the hot air blower of the device, the moisture is discharged through the outlet fan, and the feed is dried better after the moisture is discharged.

However, since the inclination angle of the discharge port is fixed, the feed will fall into the collecting device at a fixed inclination angle, and the feed will only fall into the same position. When a large amount of feed needs to be screened, the feed in the collecting device will accumulate quickly, resulting in feed overflow. The machine needs to be stopped and manually smoothed before screening can continue, which affects the feed processing efficiency. Utility Model Content

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figures 1-4As shown, the utility model provides a feed screening device for feed processing, including a shell 1 and a support frame 16, a feed port 2 is provided on the top of the shell 1, a motor 3 is fixedly connected to the outer surface of the shell 1, the motor 3 passes through the shell 1 and extends to the other side, the output end of the motor 3 is fixedly connected to the first rotating shaft 7, the first rotating shaft 7 passes through the shell 1 and extends to the outside, the end face of the first rotating shaft 7 is fixedly connected to the first pulley 9, a plurality of first springs 4 are fixedly connected to the inner surfaces of both sides of the shell 1 at equal distances, a screening plate 5 is fixed between the end faces of the plurality of first springs 4, a plurality of screening holes 6 are provided on the inner bottom of the screening plate 5, a discharge port 15 is fixedly connected to the outer surface of the shell 1, a plurality of second springs 14 are fixedly connected to the inner bottom of the support frame 16, a support plate 17 is fixedly connected between the upper end faces of the plurality of second springs 14, and the top of the support plate 17 is fixedly connected to A limit frame 18, a collector 19 is provided on the inner surface of the limit frame 18, the inner surface of the support frame 16 is rotatably connected to the second rotating shaft 12, one end of the second rotating shaft 12 passes through the support frame 16 and extends to the outside, the end face of the second rotating shaft 12 is fixedly connected to the second pulley 11, a belt 10 is provided between the outer surfaces of the first pulley 9 and the second pulley 11, the screen plate 5 is designed to be inclined, the screen plate 5 is matched with the position of the discharge port 15, the outer shell 1 and the feed port 2 are connected, and the feed port 2 is above the screen plate 5, the outer surface of the first rotating shaft 7 is symmetrically fixedly connected to the first cam 8, the outer surface of the second rotating shaft 12 is symmetrically fixedly connected to the second cam 13, the first cam 8 is matched with the position of the screen plate 5, the second cam 13 is matched with the position of the support plate 17, the discharge port 15 is designed to be inclined, and the collector 19 is located below the discharge port 15.

[0023] The effect achieved by the entire embodiment 1 is that, when the device is used, the feed to be screened is poured into the feed port 2 at the top of the shell 1, and the poured feed enters the screening plate 5 through the feed port 2, at which time the motor 3 is driven, and the first shaft 7 at the output end of the motor 3 starts to rotate, and the first shaft 7 drives the first cam 8 and the first pulley 9 to rotate. When the first cam 8 rotates, the screening plate 5 moves up and down, and the first springs 4 on both sides of the screening plate 5 are compressed and rebounded under the movement of the screening plate 5, and the screening plate 5 is in a vibrating state. At this time, the feed on the screening plate 5 vibrates synchronously, and the vibration can screen non-feed objects through the screening holes 6. At this time, the screening is completed, and the screened feed enters the discharge port 15 through the inclined screening plate 5, and the discharge port 15 sends the feed into the collector 19. The pulley 9 and the second pulley 11 are connected by a belt 10. When the first pulley 9 rotates, the second pulley 11 also rotates. The second pulley 11 drives the second rotating shaft 12 to rotate, and the second rotating shaft 12 drives the second cam 13 to rotate. When the second cam 13 rotates, the second spring 14 at the bottom of the support frame 16 will be compressed and rebounded. The second spring 14 will move the supporting plate 17 above the support frame 16. The limit frame 18 above the supporting plate 17 drives the collector 19 to vibrate together. When the feed in the screening plate 5 falls into the collector 19 from the discharge port 15, the feed will not accumulate at the same position inside the collector 19 due to the vibration factor, which solves the problem that the feed overflow in the prior art requires shutdown and manual smoothing operation before continuing screening, affecting the feed processing efficiency.

[0024] Example 2, as Figures 1-4 As shown, the outer surface of the shell 1 is fixedly connected to the motor 3, the motor 3 passes through, and the output end of the motor 3 is fixedly connected to the first rotating shaft 7, the first rotating shaft 7 passes through the shell 1 and extends to the outside, the end face of the first rotating shaft 7 is fixedly connected to the first pulley 9, and a belt 10 is arranged between the outer surfaces of the first pulley 9 and the second pulley 11. The outer surface of the first rotating shaft 7 is symmetrically fixedly connected to the first cam 8, and the outer surface of the second rotating shaft 12 is symmetrically fixedly connected to the second cam 13. The first cam 8 matches the position of the screen plate 5, and the second cam 13 matches the position of the support plate 17.

[0025] The effect achieved by the entire embodiment 2 is that when feed screening is carried out, when the motor 3 is driven, the first pulley 9 drives the second pulley 11 through the belt 10, and the first pulley 9 vibrates the screening plate 5 through the first cam 8 on the first rotating shaft 7. At the same time, the second pulley 11 vibrates the collector 19 through the second cam 13 on the second rotating shaft 12. Through the mutual cooperation of the motor 3 and the first pulley 9, the second pulley 11 and the belt 10, the driving motor 3 can complete the screening and collection work, effectively reducing the operating cost of the device.

[0026] Working principle: When the device is used, the feed to be screened is poured into the feed port 2 at the top of the shell 1. The poured feed enters the screening plate 5 through the feed port 2. At this time, the motor 3 is driven, and the first shaft 7 at the output end of the motor 3 starts to rotate. The first shaft 7 drives the first cam 8 and the first pulley 9 to rotate. When the first cam 8 rotates, the screening plate 5 moves up and down. The first springs 4 on both sides of the screening plate 5 are compressed and rebounded under the movement of the screening plate 5. The screening plate 5 is in a vibrating state. At this time, the feed on the screening plate 5 vibrates synchronously. The vibration can screen non-feed objects through the screening holes 6. At this time, the screening is completed. The screened feed enters the outlet through the inclined screening plate 5. The feed port 15 and the discharge port 15 send the feed into the collector 19. Since the first pulley 9 and the second pulley 11 are connected by a belt 10, when the first pulley 9 rotates, the second pulley 11 will also rotate, and the second pulley 11 drives the second rotating shaft 12 to rotate, and the second rotating shaft 12 drives the second cam 13 to rotate. When the second cam 13 rotates, the second spring 14 at the bottom of the support frame 16 will be compressed and rebounded, and the second spring 14 will cause the supporting plate 17 above the support frame 16 to move to achieve a vibration effect. When the feed in the screening plate 5 falls into the collector 19 from the discharge port 15, due to the vibration factor, the feed will not accumulate at the same position inside the collector 19, and the screening is completed.
