Description

Technical Field

[0001] This utility model relates to the field of feed processing, and more specifically, to a feed screening device for livestock feed processing. Background Technology

[0002] Livestock feed processing refers to the production process and industrial system of processing grains, agricultural by-products and feed raw materials produced by planting industry according to scientific formulas and specific processes (including physical, chemical or biological methods) to produce commercial compound feed that is nutritionally balanced, palatable, easy to store and feed. Screening machines are used in the feed processing process to separate different particle sizes in the feed.

[0003] In existing technologies, existing screening mechanisms cannot clean the screens while vibrating during screening. Furthermore, during actual screening, the material initially accumulates on top of the first screen, which can easily lead to blockage. Vibration alone cannot effectively achieve rapid screening. Therefore, a feed screening device that can vibrate, clean, and prevent accumulation is needed. Utility Model Content

It can achieve continuous vibration of the screen and periodic cleaning of the screen surface using a driving structure. At the same time, during the cleaning process, the material on the screen surface can be cut and broken up to prevent accumulation from affecting the vibration screening effect, thus improving the overall working efficiency of the screening device.

[0005] 2. Technical Solution To solve the above problems, the present invention adopts the following technical solution.

[0020] Example: Please see Figure 1-5A feed screening device for livestock feed processing includes a screening cylinder 1, and further includes... A drive structure 3 is set at the bottom of the screen cylinder 1. The drive structure 3 includes a motor 301 and a mounting frame 304 fixedly installed inside the screen cylinder 1. The output shaft of the motor 301 is fixedly sleeved with a gear 302. A connecting shaft is rotatably installed on the top of the mounting frame 304. A gear 305 and a semi-helical gear 306 are fixedly installed on the surface of the connecting shaft respectively. The vibrating screening mechanism 4 is installed inside the screening cylinder 1, and a cleaning mechanism 5 is rotatably installed above each of the vibrating screening mechanisms 4. It should be noted that the screen 402 in this application is from... Figure 1 As can be seen, its surface is set as a sloping structure. In this way, during the vibration process, the screened material will move towards the discharge pipe 2 to complete the corresponding discharge operation. The surface of the lowest screen 402 is in a closed state, so there is no need to worry about the feed falling into the working area of ​​the drive structure 3. It should also be noted that the filter holes of the top screen 402 are larger than those of the middle screen 402 to achieve the effect of multi-stage screening. The vibrating screening mechanism 4 includes a main shaft 401. Three screens 402 are fixedly installed on the surface of the main shaft 401. A spring rod 403 is movably installed at the bottom of the outer side of each screen 402. The outer side of the spring rod 403 is fixedly connected to the inner wall of the screening cylinder 1. A connecting pipe 404 is fixedly connected to the bottom of the main shaft 401. A connecting ring 405 is fixedly connected to the outer side of the connecting pipe 404. A rotatable 406 is also installed in the middle section of the main shaft 401. Limiting rings 407 are fixedly connected to both the upper and lower ends of the 406. A vertical groove 408 is opened on the surface of the 406. A connecting rod 303 is rotatably connected to the outer side of the gear 1 302. The top end of the connecting rod 303 and the connecting ring 405 are rotatably connected to each other. The surfaces of the gear 1 302 and the gear 2 305 mesh with each other. Specifically, the spring rod 403 consists of a spring and a fixed rod. The fixed rod is fixed to the inner wall of the screening machine cylinder 1 and can also be movably connected with the screen 402. In addition, a spring is set between the screen 402 and the fixed rod to provide corresponding buffering capacity when it moves up and down, thereby improving the service life of the device. Secondly, the limiting ring 407 can ensure that the entire 406 rotates inside the main shaft 401 without dislocation. Finally, the rotational connection of the connecting rod 303 and the connecting ring 405 is used to realize the conversion of the rotation trajectory of the gear 302 into the vertical lifting trajectory of the entire connecting pipe 404. The number of the two helical gears 306 is two, and the two helical gears 306 are symmetrically distributed on the left and right. The cleaning mechanism 5 includes a sleeve shaft 501 rotatably installed inside the main shaft 401. The bottom end of the sleeve shaft 501 is fixedly connected to a helical gear 502. The surface of the helical gear 502 meshes with the helical gear 306. A cross plate 503 is also fixedly connected to the surface of the sleeve shaft 501. A rotating ring 505 is fixedly connected to the outer side of the cross plate 503. A cleaning brush 504 is fixedly connected to the bottom end of the cross plate 503. A dividing plate 506 is fixedly connected to the top end of the cross plate 503. The rotating ring 505 is rotatably installed on the inner wall of the screening machine cylinder 1. The bottom end of the cleaning brush 504 is attached to the top surface of the screen 402. Specifically, the symmetrical arrangement of the semi-helical gears 306 allows the gear 2 305 to rotate one revolution, thereby driving the semi-helical gear 306 to rotate one revolution. However, the helical gear 502 meshing with it can be controlled to perform a corresponding half-reciprocating movement, thereby effectively preventing the screen at the top of the screen 402 from clumping. It should be noted that the bottom end of the dividing plate 506 and the connection between it and the cross plate 503 are reinforced with ribs to ensure the overall stability during rotation, prevent breakage, and improve the service life of the device. Finally, the cleaning brush 504 can limit the rotation of the entire sleeve shaft 501 to prevent deviation. The working principle of this utility model is as follows: the material is poured into the screening cylinder 1 from the top, the motor 301 is started to drive the gear 302, the gear 302 drives the connecting rod 303 to cooperate with the connecting ring 405 to periodically raise and lower the main shaft 401, thereby completing the rapid vibration of the screen 402 as a whole, thus vibrating and screening the material. During the process, the gear 302 drives the gear 305 to rotate, so that the semi-helical gear 306 drives the helical gear 502 to rotate. Finally, the cleaning brush 504 cleans the surface of the screen 402, and the dividing plate 506 divides the material to prevent agglomeration and improve screening efficiency. The material is discharged from the corresponding discharge pipe 2 in sequence after screening.

[0021] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
