Description

Technical Field

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

[0002] In the poultry farming industry, feed quality directly affects the growth, health, and profitability of poultry. Screening of raw materials is a crucial step in feed production. Screening not only effectively removes impurities, ensuring feed purity, but also allows for fine grading of raw materials according to the poultry's growth stage and nutritional needs, thus meeting the requirements of different feed formulations.

[0003] As a key piece of equipment for screening feed, the performance of vibrating screens directly affects the quality of feed and screening efficiency. However, existing vibrating screens have the problem that feed tends to accumulate in the same position of the screening frame, resulting in uneven screening, low efficiency, high maintenance costs, and low practicality. Utility Model Content

[0004] The purpose of this utility model is to provide a vibrating screen for poultry feed production, which solves the problem mentioned in the background art that when existing vibrating screens are used, feed tends to accumulate directly in the same position of the screening frame, resulting in uneven screening and low efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibrating screen for poultry feed production, comprising a screening box, a feeding box connected to the top of the screening box, a rotating ring rotatably connected to the top opening of the feeding box, a feeding pipe fixedly connected to the bottom of the rotating ring, a transmission rod fixedly connected to the bottom of the feeding pipe, and the bottom end of the transmission rod fixedly connected to the tail end of the transmission shaft of a servo motor.

[0006] In this technical solution, a feeding pipe is installed in the feeding box. The feeding pipe can rotate under the drive of the transmission rod, thereby scattering the added feed at different positions of the screening frame, reducing accumulation and improving screening efficiency.

[0007] Preferably, a support frame is fixedly connected between the left and right inner sidewalls of the screening box, a central block is fixedly connected to the top of the support frame, the transmission rod passes vertically through the central block, and the servo motor is fixedly connected to the bottom center of the support frame.

[0008] Preferably, an annular pad is fixedly connected to the inner wall of the screening box above the support frame, and a number of springs are fixedly connected to the top of the annular pad in a circumferential array, and a screening frame is fixedly connected to the top of the springs.

[0009] Preferably, the inner wall of the screening box is rotatably connected to two crossbars. One end of each crossbar passes through the surface of the central block and is rotatably connected to the central block through a bearing seat. The end of each crossbar located inside the central block is fixedly connected to a driven bevel gear, which meshes with a driving bevel gear fixedly sleeved on the outer wall of the transmission rod.

[0010] Preferably, a cam is fixedly sleeved on the surface of the crossbar, and a push block is fixedly connected to the bottom surface of the screening frame directly above the cam.

[0011] Preferably, a guide slope is fixedly connected to the outer edge of the top of the screening frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a feeding pipe in the feeding box, which can rotate under the drive of the transmission rod, thereby scattering the added feed at different positions of the screening frame, reducing accumulation and improving screening efficiency.

[0014] 2. This utility model, by setting a transmission rod and a crossbar on the inner side of the screening box, enables the rotation of the feed pipe and the vibration of the screening frame to be driven simultaneously by a servo motor, thereby reducing the structure required for the drive, reducing maintenance costs, and providing practicality and convenience to the device.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0020] A vibrating screen for producing poultry feed, see [link / reference] Figures 1 to 2The system includes a screening box 1, with a feed box 101 connected to the top of the screening box 1. A rotating ring 2 is rotatably connected to the top opening of the feed box 101. A discharge pipe 3 is fixedly connected to the bottom of the rotating ring 2. A transmission rod 4 is fixedly connected to the bottom of the discharge pipe 3. The bottom end of the transmission rod 4 is fixedly connected to the tail end of the transmission shaft of the servo motor 401. When the feed is poured, the servo motor 401 starts and drives the transmission rod 4 to rotate. During the rotation, the discharge pipe 3 will rotate, thereby scattering the feed at different positions of the screening frame 9, reducing accumulation and improving screening efficiency.

[0021] Specifically, such as Figure 2 As shown, two crossbars 5 are rotatably connected to the inner wall of the screening box 1. One end of the crossbar 5 passes through the surface of the central block 102 and is rotatably connected to the central block 102 through a bearing seat. The outer surface of the crossbar 5 is fixedly connected to the inner ring of the bearing seat, and the outer ring of the bearing seat is fixedly connected to the inner wall of the guide slope 901 of the central block 102, ensuring that the crossbar 5 rotates normally without falling off. A driven bevel gear 501 is fixedly connected to one end of the crossbar 5 inside the central block 102. The driven bevel gear 501 meshes with the driving bevel gear 402 fixedly sleeved on the outer wall of the transmission rod 4. After the rotating rod rotates, the driven bevel gear 501 and the crossbar 5 will rotate through the driving bevel gear 402.

[0022] Specifically, such as Figure 2 As shown, a cam 6 is fixedly sleeved on the surface of the crossbar 5, and a push block 10 is fixedly connected to the bottom surface of the screening frame 9 directly above the cam 6. After the crossbar 5 is driven to rotate by the transmission rod 4, the cam 6 on the surface of the crossbar 5 will rotate. During the rotation, it will continuously push the push block 10 and the screening frame 9, thereby generating vibration and screening the feed.

[0023] Furthermore, such as Figure 2 As shown, a support frame 11 is fixedly connected between the left and right inner walls of the screening box 1. A center block 102 is fixedly connected to the top of the support frame 11. The transmission rod 4 passes vertically through the center block 102. The servo motor 401 is fixedly connected to the bottom center of the support frame 11. The center block 102 mainly serves to support the servo motor 401 and the crossbar 5.

[0024] It is worth noting that, such as Figure 2 As shown, an annular pad 7 is fixedly connected to the inner wall of the screening box 1 above the support frame 11. Several springs 8 are fixedly connected to the top of the annular pad 7 in a circular array. A screening frame 9 is fixedly connected to the top of the springs 8. After the screening frame 9 and the push block 10 are continuously pushed and lifted, they will vibrate up and down under the pulling action of the springs 8, thereby screening the feed. A guide slope 901 is fixedly connected to the outer edge of the top of the screening frame 9. The guide slope 901 can concentrate the feed at the edge to the center, making screening more convenient.

[0025] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

[0026] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
