Technical Field

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

[0002] Feed is a type of food used to raise animals in animal husbandry. Feed is made from a mixture of soybeans, soybean meal, corn, grains, etc. Currently, feed production includes pelleted, powdered, or other shapes. To ensure uniform feed pellets, feed pellets of different sizes produced during the manufacturing process are packaged and sold separately. Usually, they need to be screened by a screening device so that feed of different qualities can be priced and sold separately to maximize economic benefits.

[0003] In the prior art, such as the utility model with publication number CN213001145U, a raw material screening device for pig feed production and processing is disclosed. This device includes a base plate, a first screening box mounted on one side of the top of the base plate, a first screen mounted inside the first screening box, a first vibrating motor mounted on one side of the bottom of the first screening box, a first discharge port on one side of the first screening box, and a second screening box located below the first discharge port. The second screening box is mounted on one side of the top of the base plate, a second screen mounted inside the second screening box, a second vibrating motor mounted on one side of the bottom of the second screening box, and a second discharge port on one side of the second screening box. This utility model, by changing the structure of the raw material screening device, achieves secondary screening of pig feed raw materials, thereby separating out small particles that can be directly used, avoiding further processing of directly usable small particles and residue, reducing processing time and lowering processing costs.

[0004] However, the above-mentioned device has the following problems: most existing screening equipment uses screen plates with different apertures for screening, but this screening device requires multiple screenings of the feed, which takes a long time and has low efficiency. Furthermore, multiple screenings can easily damage the formed feed and affect its quality. At the same time, screening can easily cause blockages. Therefore, we propose a screening device for feed production to solve the above problems. Utility Model Content

[0026] Please see Figure 1-5 An embodiment of this utility model provides a screening device for feed production, including a support frame 1 and a first screening cylinder 2. The first screening cylinder 2 is installed inside the support frame 1. A feed inlet 3 is fixedly installed on the right side of the support frame 1. First screening holes 4 are equidistantly opened on the surface of the first screening cylinder 2. An adjustment component 5 is provided on the outside of the first screening cylinder 2.

[0027] The adjustment component 5 includes a fixed block 51, a servo motor 52, a drive gear 53, a second screening cylinder 54, a driven gear 55, and a second screening hole 56. Fixed blocks 51 are installed on both sides of the first screening cylinder 2. A servo motor 52 is installed inside the fixed block 51. A drive gear 53 is provided on one side opposite to the two sets of servo motors 52. The second screening cylinder 54 is rotatably connected to the outside of the first screening cylinder 2.

[0028] The anti-clogging component 6 includes a fixed rod 61, a movable rod 62, a brush plate 63, and a spring 64. The inner wall of the support frame 1 is provided with a fixed rod 61, the movable rod 62 is provided inside the fixed rod 61, the front end of the movable rod 62 is provided with a brush plate 63, and the fixed rod 61 is provided with a spring 64.

[0029] This device solves the problems of low screening efficiency, easy impact on feed quality, and easy clogging during screening caused by multiple screenings with different apertures, through the adjustment of component 5 and anti-clogging component 6.

[0030] Furthermore, a connecting rod 7 is connected internally to the first screening cylinder 2, and a guide plate 8 is fixedly connected to the outside of the connecting rod 7. The guide plate 8 is spiral-shaped, and the first screening holes 4 are divided into three groups, with their diameters decreasing sequentially from left to right. Figure 3 As shown, this structure is used to rotate via the connecting rod 7 and the guide plate 8, so as to guide the feed during the screening process, thereby making the feed fall from the first screening hole 4 better, and increasing the device's ability to screen feed to different grades.

[0031] Furthermore, the diameter of the second screening hole 56 is the same as that of the first screening hole 4, the driven gear 55 meshes with the driving gear 53, both ends of the second screening cylinder 54 are rotatably connected to the first screening cylinder 2, and the servo motor 52 is fixedly installed inside the fixed block 51. Figure 4 As shown, this structure is used to drive the drive gear 53 to rotate by starting the servo motor 52. The drive gear 53 and the driven gear 55 mesh with each other, causing the second screening cylinder 54 to rotate. This adjusts the area of ​​the second screening hole 56 that overlaps with the first screening hole 4, meeting the screening requirements of different sizes of feed and improving the applicability of the device.

[0032] Furthermore, the rear end of the fixed rod 61 is fixedly connected to the inner wall of the support frame 1, the movable rod 62 is movably connected to the fixed rod 61, the brush of the brush plate 63 is in contact with the surface of the second screening cylinder 54, and the two ends of the spring 64 abut against the inner walls of the movable rod 62 and the fixed rod 61, respectively. Figure 5 As shown, this structure is used to push the movable rod 62 to attach the brush plate 63 to the surface of the second screening cylinder 54 through the elastic action of the spring 64, so as to clean the second screening hole 56 on the surface of the second screening cylinder 54 and prevent feed from getting stuck in the second screening hole 56.

[0033] Furthermore, a partition 9 is movably connected to the bottom of the first screening cylinder 2. The partition 9 is located in the gap between the first screening holes 4, and ball bearings are provided on the upper surface of the partition 9. Figure 3 As shown, this structure is used to guide and classify feed of different sizes through the partition 9, thereby facilitating collection and storage.

[0034] Furthermore, a guide groove 11 is provided inside the discharge port 10, and the guide groove 11 is funnel-shaped. For example... Figure 3 As shown, this structure is used to guide the sorted feed through the guide channel 11, so that it can flow out quickly.

[0035] Furthermore, a limit ring is fixedly connected to the inner end of the movable rod 62, and a sliding groove adapted to the limit ring is provided on the inner side of the fixed rod 61. For example... Figure 5 As shown, this structure is used to prevent the movable rod 62 from disengaging from the fixed rod 61 by means of a limiting ring, thereby limiting the movable rod 62.

[0036] Working principle: When using, such as Figure 1 As shown, feed is poured in through inlet 3, and the first screening cylinder 2 is started to screen the feed. Figure 4As shown, when the screening size needs to be adjusted, the servo motor 52 is started, which drives the drive gear 53 to rotate. The drive gear 53 meshes with the driven gear 55, causing the second screening cylinder 54 to rotate. This adjusts the area where the second screening hole 56 overlaps with the first screening hole 4, meeting the screening requirements for different sizes of feed. Figure 3 As shown, the connecting rod 7 and the guide plate 8 are rotated by the first screening cylinder 2, guiding the feed inside the first screening cylinder 2. The feed passes through the first screening holes 4 of different diameters in sequence and falls from the first screening hole 4 and the second screening hole 56. Figure 5 As shown, when the first screening cylinder 2 rotates, the elastic action of the spring 64 pushes the movable rod 62 to press the brush plate 63 against the surface of the second screening cylinder 54, cleaning the second screening hole 56 on the surface of the second screening cylinder 54, preventing feed from getting stuck in the second screening hole 56. Feed of different sizes flows out from the discharge port 10 and is collected after being guided by the partition plate 9 and the guide groove 11. The above is the complete working principle of this utility model.
