Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of screening devices, and more specifically, to a screening device for pig feed production. Background Art
[0002] In the process of pig feed production, the screening link is a key step to ensure uniform feed particles, remove impurities, and improve feed quality. Traditional pig feed screening devices mostly use fixed sieves or vibrating screens for screening. These devices often have some problems during the screening process, such as low screening efficiency, easy clogging of sieve holes, uneven screening caused by feed accumulation during screening, etc. Especially when dealing with feeds with high humidity or high viscosity, these problems are particularly prominent, seriously affecting the screening effect and production efficiency of the feed.
[0003] Specifically, traditional screening devices usually lack a flexible material control mechanism and cannot adjust the feeding speed in real time according to the screening load. As a result, when the screening load is large, the feed is likely to accumulate on the sieve, which not only increases the difficulty of screening but also may cause the sieve to clog, affecting the screening effect. In addition, the clogging problem of the sieve during the screening process is also one of the key factors restricting the screening efficiency. Once the sieve holes are clogged, it will directly lead to a decrease in screening efficiency and even require shutdown for cleaning, increasing production costs and time costs. Therefore, in view of the above technical problems, a screening device for pig feed production is proposed here. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a screening device for pig feed production, which can facilitate the flexible adjustment of the start and stop of feeding according to the load of the screened feed, avoid excessive feed accumulation and inability to screen, and vibrate the sieve plate when the sieve holes of the sieve plate are clogged to complete the dredging of the sieve holes inside the sieve plate, effectively ensuring the normal operation of the screening work.
[0005] The utility model is realized through the following technical solutions:
[0006] A screening device for pig feed production, comprising:
[0007] A device main body, on the upper side of which a feeding pipe is fixedly connected;

An abutting rod is fixedly connected to the outside of the first rotating shaft, and the number of abutting rods is two and they are symmetrically installed and abut against the outside of the baffles;
[0009] A sieve plate is rotatably connected to the inside of the device body. A support plate is fixedly connected to the inside of the device body, and the end of the sieve plate abuts against the upper side of the support plate. A second motor is fixedly connected to the outside of the device body, and a lifting mechanism is installed inside the device body;
[0010] An opening is formed in the bottom of the device body, and a collection box is placed inside the opening.
[0011] A rotating rod is fixedly connected to the inside of the device body, and the baffle is rotatably connected to the rotating rod. The baffle is slidably connected to the inner wall of the device body.
[0012] The reset mechanism includes a mounting seat, a sliding rod, a sliding plate, a spring and a telescopic rod. The mounting seat is fixedly connected to the device body. The sliding rod is slidably connected to the outside of the mounting seat. A sliding plate is slidably connected to the inside of the mounting seat, and the sliding plate is fixedly connected to the sliding rod.
[0013] Both the spring and the telescopic rod are fixedly connected to the sliding plate and the mounting seat, and the spring is installed on both sides of the telescopic rod. The sliding rod abuts against the outside of the baffle.
[0014] A rotating shaft is fixedly connected to the inside of the device body, and the sieve plate is rotatably connected to the rotating shaft. The sieve plate is slidably connected to the inner wall of the device body.
[0015] The lifting mechanism includes a second rotating shaft and a pressing plate. The second rotating shaft is rotatably connected to the inside of the device body, and the second rotating shaft is fixedly connected to the second motor.

[0016] A controller is fixedly connected to the outside of the device body, and the controller is signal-connected to the first motor and the second motor.
[0017] The technical solution of the present utility model has at least the following beneficial effects:
[0018] 1. For this screening device for pig feed production, by operating the first motor, the baffle can be rotated to open the two baffles, so that the pig feed can be fed and screened from between the bottoms of the two baffles. However, when the screening load is large, the motor can be operated to separate the two pressing rods from the baffle. Then, under the action of the spring, the baffle can be reset to its original state, thus stopping the feeding of the pig feed. This can facilitate the flexible adjustment of the start and stop of the feeding according to the screening load of the feed, and avoid excessive accumulation of the feed and inability to screen.
[0019] 2. The screening device for pig feed production operates the second motor to rotate the abutting plate. Since the abutting plate abuts against the bottom of the sieve plate, the sieve plate can be lifted by a certain distance. When the abutting plate is disengaged from the sieve plate, at this time, under the action of gravity, the end of the sieve plate will collide with the support plate, causing the entire sieve plate to vibrate, so that the feed blocking the sieve holes can be shaken out, thus completing the dredging of the sieve holes in the sieve plate and effectively ensuring the normal operation of the screening work.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.
[0027] Embodiment 1
[0028] Please refer to Figures 1-3, a screening device for pig feed production proposed in this application includes a device main body 1, a baffle 4, a sieve plate 14, and an opening 19. A feeding pipe 2 is fixedly connected to the upper side of the device main body 1. The baffle 4 is rotatably connected to the inside of the device main body 1, and the number of baffles 4 is two groups and they are symmetrically installed. A reset mechanism is installed inside the device main body 1. A first motor 10 is fixedly connected to the upper side of the device main body 1. A first rotating shaft 11 is fixedly connected to the lower side of the first motor 10, and the first rotating shaft 11 is rotatably connected to the device main body 1. An abutting rod 12 is fixedly connected to the outside of the first rotating shaft 11, and the number of abutting rods 12 is two groups and they are symmetrically installed and abut against the outside of the baffle 4.
[0029] A rotating rod 3 is fixedly connected to the inside of the device main body 1, and the baffle 4 is rotatably connected to the rotating rod 3. The baffle 4 is slidably connected to the inner wall of the device main body 1.
[0030] The reset mechanism includes a mounting seat 5, a sliding rod 6, a sliding plate 7, a spring 8, and a telescopic rod 9. The mounting seat 5 is fixedly connected to the device main body 1. The sliding rod 6 is slidably connected to the outside of the mounting seat 5. A sliding plate 7 is slidably connected to the inside of the mounting seat 5, and the sliding plate 7 is fixedly connected to the sliding rod 6.
[0031] The spring 8 and the telescopic rod 9 are both fixedly connected to the sliding plate 7 and the mounting seat 5, and the spring 8 is installed on both sides of the telescopic rod 9. The sliding rod 6 abuts against the outside of the baffle 4.
[0032] Based on the working principle of the screening device for pig feed production in Embodiment 1, when screening pig feed during production, the pig feed to be screened can be put into the device main body 1 through the feeding pipe 2. At this time, the pig feed will be concentrated in the area between the two baffles 4. Due to the force between molecules, the pig feed will be blocked between the two baffles 4. When screening is required, the first motor 10 can be operated to make the first rotating shaft 11 drive the abutting rod 12 to abut against the baffle 4 and rotate, so that the two baffles 4 can be opened. At the same time, the sliding rod 6 is abutted to drive the sliding plate 7 to compress the spring 8, so that the pig feed can be discharged from the bottom between the two baffles 4 for screening. However, when the screening load is large, the motor can be operated to make the two abutting rods 12 disengage from the baffle 4. Thus, under the action of the spring 8, the baffle 4 can be reset to its original state, thereby stopping the feeding of the pig feed. This can facilitate flexibly adjusting the start and stop of feeding according to the screening load of the feed, and avoid excessive accumulation of feed and inability to perform screening.
[0033] Embodiment 2
[0034] Please refer to Figures 1-5, based on the first embodiment, the sieve plate 14 is rotatably connected to the inside of the device main body 1. A support plate 15 is fixedly connected to the inside of the device main body 1, and the end of the sieve plate 14 abuts against the upper side of the support plate 15. A second motor 16 is fixedly connected to the outside of the device main body 1. A lifting mechanism is installed inside the device main body 1. An opening 19 is formed at the bottom of the device main body 1, and a collection box 20 is placed inside the opening 19.
[0035] A rotating shaft 13 is fixedly connected to the inside of the device main body 1, and the sieve plate 14 is rotatably connected to the rotating shaft 13. The sieve plate 14 is slidably connected to the inner wall of the device main body 1.
[0036] The lifting mechanism includes a second rotating shaft 17 and a pressing plate 18. The second rotating shaft 17 is rotatably connected to the inside of the device main body 1, and the second rotating shaft 17 is fixedly connected to the second motor 16. The pressing plate 18 is fixedly connected to the second rotating shaft 17, and the pressing plate 18 abuts against the bottom of the sieve plate 14.
[0037] A controller 21 is fixedly connected to the outside of the device main body 1, and the controller 21 is in signal connection with the first motor 10 and the second motor 16.
[0038] In this embodiment, when the feed is fed onto the sieve plate 14, the screening of the feed can be carried out. After a long time of screening work, the sieve holes of the sieve plate 14 will be clogged to a certain extent. At this time, the second motor 16 can be operated to drive the pressing plate 18 to rotate by the second rotating shaft 17. Since the pressing plate 18 abuts against the bottom of the sieve plate 14, the sieve plate 14 can be lifted by a certain distance until the pressing plate 18 is separated from the sieve plate 14. At this time, under the action of gravity, the end of the sieve plate 14 will collide with the support plate 15, so that the whole sieve plate 14 vibrates, and the feed clogging the sieve holes can be shaken out, thus completing the dredging of the sieve holes in the sieve plate 14 and effectively ensuring the normal operation of the screening work.
