Description

Technical Field

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

[0002] Feed is a general term for the food of animals raised by all people. In a narrower sense, feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes more than ten kinds of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meals, additives, whey powder, oils, meat and bone meal, grains, and sweet sorghum. In the feed production process, some special nutrients need to be added, such as amino acids, whey powder, and meat and bone meal. These added ingredients are trace elements and need to be added regularly and in quantitative amounts during the feed processing and production process.

[0003] When the feed to be screened is fed into the equipment through the feeding structure, the feed tends to accumulate locally on the surface of the filter screen. In particular, feed in a humid environment may clump together and adhere to the screen. This not only quickly occupies the effective screening space, but also often causes the filter screen to become clogged. Subsequent feed cannot make full contact with the filter screen, and manual cleaning can only be done by stopping the machine at regular intervals. This seriously disrupts the continuity of production, reduces the overall production efficiency, and makes it difficult to meet the high-efficiency and continuous operation requirements of modern feed production. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a screening device for feed production, which solves the technical problem that feed tends to accumulate and clump on the filter screen after being fed into the screening equipment, leading to screen blockage, insufficient screening, the need for manual shutdown for cleaning, interruption of production continuity, low efficiency, and difficulty in meeting the needs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A screening device for feed production includes a screening box with a chute extending through its side wall. A feed inlet communicating with the chute is extending through the upper end of the screening box. A feed tray is fixedly installed at the lower end of the screening box. A fixed frame is slidably installed within the chute. A filter screen frame is disposed within the fixed frame, and a filter screen body is fixedly installed on the filter screen frame. Installation strips are symmetrically fixedly installed inside the screening box. A drive motor is fixedly installed between two installation strips. A cam is fixedly installed on the output shaft of the drive motor. A transmission structure cooperating with the cam is provided at the lower end of the filter screen frame. This device achieves efficient feed screening, prevents feed accumulation and clogging of the filter screen, eliminates the need for frequent manual cleaning, ensures continuous production, and improves the overall efficiency of feed production.

[0006] Preferably, a rectangular frame is fixedly installed inside the fixed frame, and sliding columns are fixedly installed at the four corners of the upper end of the rectangular frame to provide a stable support structure for the filter screen frame. The sliding columns form a guiding foundation to ensure accurate subsequent movement of the filter screen and improve the operational stability of the device.

[0007] Preferably, the filter screen frame has grooves at its four corners, and four sliding columns are respectively installed in the four grooves, so that the filter screen frame and the fixed frame form a sliding fit, which limits the movement trajectory of the filter screen, avoids deviation, and ensures that the screening action is carried out in an orderly manner.

[0008] Preferably, the transmission structure includes two convex balls and two fixed columns fixedly installed at the lower end of the filter screen frame, forming a stable transmission carrier, which, together with the cam, achieves efficient power transmission and provides reliable structural support for the reciprocating movement of the filter screen.

[0009] Preferably, the two convex balls are located between the two fixed columns, and each of the two fixed columns is rotatably fitted with a movable sleeve that cooperates with the cam, which optimizes the power transmission path, reduces friction between the cam and the fixed columns, reduces component wear, and ensures the continuity and stability of the transmission.

[0010] Preferably, the sliding column and the column groove are in clearance fit, with the sliding column embedded in the column groove. This fit allows the filter screen frame to move slightly along the length of the sliding column, guided by the sliding column. This provides the filter screen with a margin of movement, buffers transmission impact, assists the filter screen in generating slight vibration, and improves the thoroughness of feed screening.

[0011] Preferably, the movable sleeve is rotatably mounted on the fixed column. When the cam rotates, it can form a contact transmission with the movable sleeve, converting the cam rotation into linear movement of the filter screen, reducing power transmission loss, ensuring stable reciprocating frequency of the filter screen, and improving the screening effect.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This equipment uses a drive motor to rotate a cam, which, in conjunction with a transmission structure, drives the filter screen frame and the fixing frame to move back and forth along the slide groove of the screening box. This prevents the feed on the filter screen from piling up and achieves efficient screening. The screened feed can be smoothly discharged through the feed tray, improving the continuity and efficiency of feed screening. Attached Figure Description

[0016] This application provides a screening device for feed production, which effectively solves the problem that in existing equipment, feed tends to accumulate and clump on the filter screen after being fed into the screening equipment, leading to screen blockage, insufficient screening, the need for manual shutdown for cleaning, interruption of production continuity, low efficiency, and inability to meet demand. This device uses a drive motor to drive a cam to rotate, which, in conjunction with a transmission structure, drives the filter screen frame and fixing frame to move back and forth along the slide groove of the screening box, making it difficult for feed to pile up on the filter screen body, while achieving efficient screening. The screened feed can be smoothly discharged through the feed tray, improving the continuity and efficiency of feed screening.

[0017] Example like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that existing equipment easily accumulates and clumps on the filter screen after feed is fed into the screening equipment, resulting in screen blockage, insufficient screening, the need for manual shutdown for cleaning, interruption of production continuity, low efficiency, and difficulty in meeting the needs. The overall idea is as follows: A screening device for feed production includes a screening box 1, a chute 2 is opened through the side wall of the screening box 1, a feeding port 3 communicating with the chute 2 is opened at the upper end, and a feeding tray 4 is fixed at the lower end; a sliding fixed frame 5 is installed in the chute 2, and a filter screen frame 11 is installed inside it, and a filter screen body 16 is fixed on the filter screen frame 11; mounting strips 8 are symmetrically installed in the screening box 1, and a drive motor 9 is fixed between the two mounting strips 8. The output shaft of the drive motor 9 is fixed with a cam 10. The lower end of the filter screen frame 11 is provided with a transmission structure that cooperates with the cam 10. The drive motor 9 drives the cam 10 to rotate, and the transmission structure drives the filter screen frame 11 and the fixed frame 5 to move back and forth along the chute 2, so as to realize the efficient screening of feed by the filter screen body 16, avoid feed accumulation, ensure production continuity, and improve overall efficiency.

[0018] A rectangular frame 6 is fixedly installed inside the fixed frame 5. The rectangular frame 6 is a frame structure. The four corners of its upper end are fixedly connected to the lower ends of four sliding columns 7. The sliding columns 7 are arranged vertically. The rectangular frame 6 provides a stable installation base for the sliding columns 7. The sliding columns 7 distributed at the four corners can precisely cooperate with the filter frame 11, providing balanced guidance for the movement of the filter frame 11 and improving the structural stability of the device.

[0019] The filter frame 11 has a rectangular frame structure with columnar grooves 12 at its four corners. The inner diameter of the grooves 12 is slightly larger than the outer diameter of the sliding columns 7. The upper ends of the four sliding columns 7 are respectively embedded in the four grooves 12. The fitting structure of the sliding columns 7 and the grooves 12 limits the direction of movement of the filter frame 11, preventing the filter frame 11 from shifting laterally during movement, and ensuring that the filter body 16 is always in the effective screening area.

[0020] The transmission structure consists of two convex balls 13 and two fixed columns 14. The convex balls 13 are spherical and the fixed columns 14 are cylindrical. Both are vertically fixed to the lower end surface of the filter frame 11. The convex balls 13 can assist in adjusting the transmission gap, and the fixed columns 14 provide a mounting carrier for the movable sleeve 15. The two work together to enable the transmission structure to stably receive the power of the cam 10 and ensure that the power transmission is uninterrupted.

[0021] Two convex balls 13 are symmetrically distributed on both sides of the centerline between two fixed columns 14. The outer peripheral surface of the fixed column 14 is smooth. The movable sleeve 15 has an annular structure. Its inner wall fits against the outer peripheral surface of the fixed column 14 and can rotate freely. The outer peripheral surface of the movable sleeve 15 contacts the contour surface of the cam 10. The arrangement of the convex balls 13 and the fixed column 14 makes the cam 10 subjected to balanced force. The rotational characteristics of the movable sleeve 15 reduce friction and wear with the cam 10, extend the service life of the component, and ensure transmission efficiency.

[0022] The sliding column 7 and the column groove 12 are fitted with a clearance. The size of the clearance is controlled within the range that allows the filter screen frame 11 to move. After the sliding column 7 is embedded in the column groove 12, the filter screen frame 11 can move slightly up and down along the length direction (vertical direction) of the sliding column 7. The clearance provides a buffer space for the filter screen frame 11. The slight vertical movement can cause the filter screen body 16 to vibrate slightly, which helps to break up the feed, improve the thoroughness of screening, and avoid clogging of the mesh.

[0023] The movable sleeve 15 is rotated on the fixed column 14 with an interference fit, ensuring that the movable sleeve 15 moves synchronously with the fixed column 14. When the cam 10 rotates, its protruding part can roll into contact with the outer circumferential surface of the movable sleeve 15 to form a contact transmission. The rolling contact smoothly converts the circumferential rotation of the cam 10 into the linear reciprocating movement of the filter frame 11, reducing energy loss in the power transmission process, ensuring the stability of the reciprocating frequency of the filter body 16, and improving the feed screening efficiency.

[0024] To address the problems existing in the prior art, this utility model provides a screening device for feed production. This device uses a drive motor to rotate a cam, which, in conjunction with a transmission structure, drives the filter screen frame and the fixing frame to move back and forth along the slide groove of the screening box. This prevents the feed on the filter screen from piling up, while achieving efficient screening. The screened feed can be smoothly discharged through the feed tray, improving the continuity and efficiency of feed screening.

[0025] Working principle: First, when using the filter, feed can be put into the filter body 16. Then, the drive motor 9 can be started. Under the action of the drive motor 9, the cam 10 will rotate. The rotation of the cam 10 will push the two movable sleeves 15 to move. The two movable sleeves 15 will drive the two fixed columns 14 to move. The two fixed columns 14 will drive the filter frame 11 to move. The filter frame 11 will drive the fixed frame 5 to move back and forth inside the chute 2, thereby screening the feed on the filter body 16. The filter frame 11 is designed to slide inside the chute 2, so that the feed is not easy to pile up on the filter body 16. Under the reciprocating movement, it will be pushed down by the inner wall of the screening box 1 and discharged on the feed tray 4 after screening. In the second step, when the cam 10 rotates, it will contact the convex ball 13. When the cam 10 contacts the convex ball 13, it will squeeze the convex ball 13. At this time, the convex ball 13 will be forced to move upward, which will drive the filter screen frame 11 to move upward in the slide column 7. When the cam 10 and the convex ball 13 are misaligned, the filter screen frame 11 will be reset under the action of gravity, so that the filter screen frame 11 and the filter screen body 16 can also vibrate synchronously during operation, which further enhances the screening effect of the equipment.

[0026] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
