Description

Technical Field

[0001] This utility model relates to the field of screening devices, and in particular to a raw material screening device for pig feed processing. Background Technology

[0002] Pig feed is a crucial part of pig production because different types of pigs have different nutritional needs at different growth stages. Therefore, in practice, various raw materials should be rationally combined according to specific breeding goals and the growth status of the pigs to ensure the health and efficient production of pigs. During the production of pig feed, raw materials need to be screened using raw material screening equipment. After screening, qualified raw materials are used for production.

[0003] According to the Chinese patent "A Multi-stage Screening Device for Easy-to-Move Pig Feed Production" (authorization announcement number CN215784921U), the device uses the interaction of a motor, worm gear, worm wheel, rotating rod, turntable, fixed shaft, rectangular groove, limiting plate, limiting rod, horizontal rod, and vertical rod to drive the right side of the first and second screens to vibrate up and down, thereby performing primary and secondary screening of pig feed raw materials. Furthermore, the interaction of a cam, push plate, push rod, spring, frame, sleeve, first T-shaped rod, second T-shaped rod, and third screen performs tertiary screening of pig feed raw materials, thus making the screening more thorough and improving the production quality of pig feed.

[0004] Although the above application can achieve multi-stage screening of raw materials, the first and second screen plates need to be installed in the box at a certain angle, which requires a large installation space. In addition, during screening, all raw materials need to move to the lowest end of the screen plate in a predetermined direction to complete the final screening operation. A large amount of raw materials will accumulate together during the screening process, which can easily cause incomplete screening of raw materials and affect the screening effect.

[0005] Therefore, a raw material screening device for pig feed processing is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a raw material screening device for pig feed processing to solve the above problems, thereby improving the issues of raw materials that cannot be screened into two or more sizes and the excessive space required.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a raw material screening device for pig feed processing, comprising:

[0008] The box body and the feeding frame, wherein the feeding frame is located at the top center of the box body;

[0009] Raw material screening mechanism, the raw material screening mechanism includes a diamond-shaped frame arranged inside the box body. Both sides of the top end of the diamond-shaped frame are embedded with large particle screening nets. Both sides of the bottom end of the diamond-shaped frame are embedded with small particle screening nets. The middle of the diamond-shaped frame is hollowed out to form a screening area. The large particle screening net is connected to the screening area, and a medium particle collection pipe connected to the screening area is arranged at the bottom end of the diamond-shaped frame. The bottom end of the medium particle collection pipe penetrates through the box body, and a vibration motor is arranged at one end of the medium particle collection pipe.

[0010] Preferably, a diversion plate is fixedly connected to the inner top wall of the screening area of the diamond-shaped frame. The diversion plate is in an overall "person" shape, and both sides of the bottom end of the diversion plate are located above the high side of the small particle screening net.

[0011] Preferably, both sides of the bottom end of the diamond-shaped frame are fixedly connected with springs, and the other ends of the springs are fixedly connected with the inner wall of the box body. The other ends of the springs penetrate through the limiting blocks and the connection between the limiting blocks and the box body.

[0012] Preferably, a flow dividing plate is fixedly connected to the middle of the top end of the diamond-shaped frame, and the lower end of the flow dividing plate is fixedly connected to the raw material screening mechanism.

[0013] Preferably, an upper collection plate is fixedly connected to the low end of the diamond-shaped frame where the small particle screening net is located, and a lower collection plate is fixedly connected to the high end of the diamond-shaped frame where the small particle screening net is located. The two lower collection plates are distributed in an inverted "eight" shape, the two upper collection plates are distributed in an "eight" shape, and the adjacent lower collection plate and upper collection plate are distributed in an "eight" shape.

[0015] Preferably, large particle discharge shells are fixedly connected to both sides of the box body, and the large particle discharge shells are fixedly connected to the box body with one end open.

[0016] The beneficial effects of the present utility model are:

[0017] By setting the diamond-shaped frame, when raw materials enter the raw material screening mechanism, they can flow evenly to both sides of the raw material screening mechanism through the flow dividing plate, avoiding the accumulation of raw materials when a large amount of raw materials enter the raw material screening mechanism and screening from one side of the screening net, resulting in incomplete screening. At the same time, the raw materials entering the raw material screening mechanism are screened from the high end of the diamond-shaped frame to both low ends at the same time, improving the screening rate. The low end of the first layer of the screening net of the diamond-shaped frame is fixedly connected to the high end of the second layer of the screening net. The raw materials passing through the first layer of screening net will be guided to the top of the second layer of screening net through the diversion plate for re-screening. While completing multi-stage screening, the required working space is reduced, improving the space utilization rate and reducing equipment costs. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] When implementing: Figure 1-4 As shown, a raw material screening device for pig feed processing includes:

[0025] The box body 100 and the feeding frame 200 are located at the top center of the box body 100;

[0026] The raw material screening mechanism 500 includes a rhomboid frame 501 set inside the housing 100. Large particle screening screens 502 are embedded on both sides of the top of the rhomboid frame 501, and small particle screening screens 503 are embedded on both sides of the bottom of the rhomboid frame 501. The middle of the rhomboid frame 501 is hollowed out to form a screening area. The large particle screening screens 502 and small particle screening screens 503 are connected to the screening area. A medium particle collection pipe 509 connected to the screening area is set at the bottom of the rhomboid frame 501. The bottom end of the medium particle collection pipe 509 penetrates the housing 100, and a vibration motor 510 is set at one end of the medium particle collection pipe 509.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown in Figure 3 , Figure 4 , a flow guide plate 508 is fixedly connected to the inner top wall of the screening area of the diamond-shaped frame 501. The flow guide plate 508 is in an overall "human" shape, and both sides of the bottom end of the flow guide plate 508 are located above the high side of the small particle screen 503.

[0028] In this embodiment, after the raw materials enter the raw material screening mechanism 500 and pass through the first layer of screening, they can be directly guided to the high end of the second layer of screen through the flow guide plate 508, which is beneficial to the full screening of the raw materials.

[0029] Both sides of the bottom end of the diamond-shaped frame 501 are fixedly connected with springs 506. The other ends of the springs 506 are fixedly connected to the inner wall of the box body 100, and the other ends of the springs 506 penetrate through the limiting blocks 507 and the connection between the limiting blocks 507 and the box body 100.

[0030] In this embodiment, when screening the raw materials, the vibration motor 510 generates vibration, which drives the vibration of the raw material screening mechanism 500. At the same time, it cooperates with the springs 506 to generate an amplitude, which can prevent the raw materials from blocking the screen holes during the screening process and can accelerate the screening rate.

[0031] A flow dividing plate 600 is fixedly connected to the middle of the top end of the diamond-shaped frame 501, and the lower end of the flow dividing plate 600 is fixedly connected to the raw material screening mechanism 500.

[0032] In this embodiment, when a large amount of raw materials are added to the feeding frame 200, the raw materials will be evenly divided into two parts by the action of the flow dividing plate 600 and enter both sides of the raw material screening mechanism 500 at the same time. The two sides of the raw material screening mechanism 500 conduct screening simultaneously, which can improve the screening rate.

[0033] As Figure 1 , Figure 2 and Figure 3 As shown in Figure 1 , Figure 2 , Figure 3 , an upper collection plate 505 is fixedly connected to the low end of the diamond-shaped frame 501 where the small particle screen 503 is located, and a lower collection plate 504 is fixedly connected to the high end of the diamond-shaped frame 501 where the small particle screen 503 is located. The two lower collection plates 504 are distributed in an inverted "eight" shape, the two upper collection plates 505 are distributed in an "eight" shape, and the adjacent lower collection plate 504 and upper collection plate 505 are distributed in an "eight" shape.

[0034] A small particle discharge shell 400 is fixedly connected to the bottom end of the lower collection plate 504, and the small particle discharge shell 400 is fixedly connected to the box body 100.

[0035] Large particle discharge shells 300 are fixedly connected to both sides of the box body 100, and the large particle discharge shells 300 are fixedly connected to the box body 100 with one end open.

[0036] In this embodiment, after being screened by the large particle screening mesh 502, large particles flow into the large particle discharge shell 300 along the surface of the large particle screening mesh 502. Small particles, after being screened, fall onto the upper collection plate 505 and the lower collection plate 504. The small particles that fall onto the upper collection plate 505 will fall again onto the lower collection plate 504, and then flow into the small particle discharge shell 400 through the lower collection plate 504. This can prevent the screened small particles from spilling into the box 100, thus making it convenient for staff to collect them.

[0037] In use, when the raw material is fed into the box 100 from the feed frame 200, it is divided into two parts after passing through the diversion plate 600 during its descent. The two parts of the raw material will respectively reach the two screening areas above the rhomboid frame 501. Under the influence of gravity and the falling speed, the raw material will flow from the high end to the low end of the rhomboid frame 501, completing the first screening. At this time, the large particles of raw material will be collected with the large particle discharge shell 300, while other raw materials will pass through the large particle screening mesh 502 and enter the screening area, falling to the guide plate 508, and then being discharged by the guide plate 508. The material is guided from the high end of the small particle screen 503 to the low end. At this time, medium particles will enter the medium particle collection pipe 509 along with the screen surface, while small particles will pass through the small particle screen 503 and fall to the upper collection plate 505 and the lower collection plate 504. The small particles falling to the upper collection plate 505 will fall to the lower collection plate 504 by gravity, and then flow into the small particle discharge shell 400 through the lower collection plate 504 to complete the classification and screening of the raw materials. During this process, the vibration motor 510 can be started to drive the rhomboid frame 501 to vibrate, and at the same time cooperate with the spring 506 to improve the screening efficiency and effect.

[0038] It should be noted that the vibration motor 510 and other devices mentioned above are all devices with relatively mature existing technology applications. The specific model can be selected according to actual needs.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
