Description

Technical Field

[0001] This utility model relates to the technical field of feed processing equipment, specifically a screening device for feed production. Background Technology

[0002] Feed is a general term for the food of animals raised by humans. In a narrower sense, feed mainly refers to the food of animals raised in agriculture or animal husbandry. During the processing of feed, it is necessary to screen the feed so that the particle size of different feeds meets the required requirements and satisfies the feed production requirements.

[0003] A search revealed the following publicly available patent: CN215088709U, which discloses a feed screening device, relating to the field of feed processing equipment technology. The device includes a body with an inlet and an outlet, a screen plate within the body, and mounting plates symmetrically slidably mounted longitudinally on two opposing inner walls of the body. The screen plate is horizontally slidably engaged between the two mounting plates. An amplitude adjustment component is vertically slidably inserted between the inner and outer sides of the bottom of each mounting plate. When the amplitude of the screen plate needs to be adjusted to change the screening effect, the operating drive unit drives the transmission unit to rise and fall within the body, causing the amplitude adjustment component to rise and fall, thereby changing the amplitude of the amplitude adjustment component.

[0004] However, the device still has the following problems during use: Since the device screens feed by vibrating the screen plate, although the screen plate can screen the feed, after a long period of use, the screen plate may be filled with damp or sticky feed, causing the screen holes to become blocked. If it is not cleaned in time, the feed will accumulate on the screen plate, reducing the screening effect and affecting the normal operation of the equipment. In view of the above situation, technical innovation is carried out on the basis of the existing device. Utility Model Content

A transmission frame 9 is fixedly connected to the inner wall of the body 1. A transmission groove 10 is provided at the bottom of the transmission frame 9. A power adjustment device is provided inside the transmission groove 10.

[0029] Please refer to Figure 2 The power adjustment device includes a transmission rod 11, which is slidably connected to the inside of a transmission groove 10. A threaded rod 14 is rotatably connected inside the transmission groove 10, and the surface of the threaded rod 14 is threadedly connected to the inside of the transmission rod 11. A connecting groove 25 is provided at the bottom of the transmission rod 11, and a connecting rod 12 is slidably connected inside the connecting groove 25. A disturbance plate 13 is fixedly connected to the bottom of the connecting rod 12, and a brush is provided at the bottom of the disturbance plate 13. A spring 26 is fixedly connected to the top of the connecting rod 12, and the top of the spring 26 is fixedly connected to the inner wall of the connecting groove 25. By sliding the connecting rod 12 up and down, the spring 26 can be compressed and reset.

[0030] Please refer to Figure 2 Two symmetrical support blocks 23 are fixedly connected to the inner wall of the body 1. The cross section of the support block 23 is "L-shaped". A movable frame 16 is provided on the top of the support block 23. A movable groove 24 is opened at the bottom of the movable frame 16. The support block 23 is slidably connected to the inside of the movable groove 24. Multiple tension springs 17 are fixedly connected to the top of the support block 23. The top of the tension springs 17 is fixedly connected to the inner wall of the movable groove 24. By sliding the movable frame 16 up and down, the tension springs 17 can be stretched and reset.

[0031] Please refer to Figure 3 The top of the movable frame 16 is fixedly connected to a limiting block 19. The limiting block 19 has a "T" shaped cross section. A filter frame 15 for screening feed is provided on the top of the limiting block 19. Multiple filter holes are opened at the bottom of the filter frame 15.

The limiting block 19 and the limiting grooves 18 are slidably connected inside.

[0032] Please refer to Figure 2Multiple ejector pins 20 are fixedly connected to the inner wall of the machine body 1. The ejector pins 20 are located below the filter frame 15. The surface of the ejector pins 20 is slidably connected to the inside of the filter hole. By making the filter frame 15 shake up and down, the ejector pins 20 can clear the feed blockage inside the filter hole.

[0033] Please refer to Figure 2 The output end of the forward and reverse motor 5 is fixedly connected to a rotating shaft via a coupling. A rotating rod 21 is fixedly connected to the outer wall of the rotating shaft. The rotating rod 21 is rotatably connected to the inside of the machine body 1. Multiple protrusions 22 are fixedly connected to the surface of the rotating rod 21. By rotating the protrusions 22, the surface of the protrusions 22 contacts the bottom of the filter frame 15, which can cause the filter frame 15 to vibrate up and down under force.

[0034] The operator starts the forward and reverse motor 5 through the controller and microcomputer structure. The output end of the forward and reverse motor 5 drives the rotating rod 21 to rotate forward and reverse through the rotating shaft. The rotating rod 21 drives the protrusion 22 to rotate. The surface of the protrusion 22 contacts the surface of the filter frame 15. The filter frame 15 is subjected to force and shakes up and down, and the tension spring 17 is continuously compressed and reset. By making the filter frame 15 shake up and down, the feed on the filter frame can be screened, separating larger feed and damp and coagulated feed. The ejector pin 20 pushes out the inside of the filter hole. The ejector pin 20 can push out the wet material attached to or blocked in the hole in time, ensuring that the screen hole is unobstructed. This effectively reduces the situation where the screen hole is blocked due to damp and sticky feed, thus reducing the frequency and workload of manual cleaning of the filter hole and reducing the possibility of equipment downtime for maintenance.

[0035] Please refer to Figure 2 The power frame 4 has a power groove 6 inside, and two symmetrical sprockets 7 are rotatably connected inside the power groove 6. The surfaces of the sprockets 7 are meshed with chains 8.

[0036] Please refer to Figure 2 The right side of the threaded rod 14 rotates through the power groove 6 and extends into it. The right side of the threaded rod 14 is fixedly connected to the left side of the upper sprocket 7. Similarly, the right side of the rotating rod 21 rotates through the power groove 6 and extends into it. The right side of the rotating rod 21 is fixedly connected to the left side of the lower sprocket 7.

[0037] The rotating rod 21 is connected to the chain 8 via the sprocket 7, which drives the threaded rod 14 to rotate in both directions. The threaded rod 14 drives the transmission rod 11 to reciprocate. The transmission rod 11 drives the disturbance plate 13 to reciprocate via the connecting rod 12. The disturbance plate 13 can agitate the feed inside the filter frame 15 through the brush set at the bottom. The agitation of the feed inside the filter frame 15 by the brush can effectively prevent the feed from accumulating during the filtration process, ensure uniform distribution of materials, and enhance filtration permeability. Secondly, the physical agitation of the brush can appropriately break up large particles or sticky substances in the feed, further improving the filtration accuracy, helping to screen out feed particles that meet the specifications, and improving the quality of the finished product. At the same time, continuous agitation can also reduce the problems of mold and deterioration caused by feed retention, extend the equipment cleaning cycle, and reduce maintenance costs.

[0038] Working principle: For this type of feed production screening device, the operator first starts the forward and reverse motor 5. The output end of the forward and reverse motor 5 drives the rotating rod 21 to rotate forward and reverse through the rotating shaft. The rotating rod 21 drives the protrusion 22 to rotate. The surface of the protrusion 22 contacts the bottom of the filter frame 15, causing the filter frame 15 to shake up and down to screen the feed. The top pin pushes out the filter holes, which can push out the wet and accumulated feed inside the filter holes to reduce clogging.

[0039] The rotating rod 21 drives the threaded rod 14 to rotate forward and backward through the meshing connection between the sprocket 7 and the chain 8. The threaded rod 14 drives the transmission rod 11 to reciprocate. The transmission rod 11 drives the disturbance plate 13 to reciprocate through the connecting rod 12. The disturbance plate 13 disturbs the feed at the bottom of the filter frame 15 through the brush set at the bottom. Due to the spring set at the top of the connecting rod 12, the disturbance plate 13 can be disturbed while shaking up and down with the filter frame 15.

[0040] Workers can loosen the bolts to remove the baffle 3 from the machine body 1, remove the baffle 3, and then pull out the filter frame 15 to process the feed screened out in the filter frame 15. At the same time, the filter frame 15 can be replaced or repaired.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
