[0001] The utility model belongs to the technical field of biological feed production, and specifically relates to a screening device for biological feed. Background Art
[0002] Biological feed refers to the general term of feed products developed through bioengineering technologies such as fermentation engineering, enzyme engineering, protein engineering, and genetic engineering, using feed raw materials and additives permitted by relevant national regulations. It is a type of feed additive that can improve feed utilization efficiency, animal health, and production performance through bioengineering technology, mainly including microbial feed additives, enzyme preparations, and oligosaccharides. During the production process of biological feed, it is necessary to crush and screen the feed raw materials. A vibrating screening device will be used during the screening process. The existing vibrating screening device has a single power source during the screening process, usually a reciprocating motion in a single direction, and the screening efficiency is relatively low.
[0003] In view of this, the present utility model is specifically proposed. Content of the Utility Model

The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.
[0024] Such as Figures 1 to 5As shown in the figure, a screening device for biological feed includes a screening box 1 and a rotary power box 10. A screening cylinder 15 is rotatably connected and installed inside the screening box 1. An opening is provided on the outer wall of the screening cylinder 15. A feeding port 8 is opened at the top of the screening box 1. A sealing cover 7 is provided at the feeding port 8. A side support 5 is fixedly arranged outside the screening box 1. A vibrator 6 is installed on the side support 5. An expansion guide sleeve 14 is arranged between the feeding port 8 of the screening box 1 and the opening of the screening cylinder 15. A support roller 17 is arranged outside the lower side of the screening cylinder 15. The support roller 17 is installed on a support shaft. Both ends of the support shaft are rotatably connected to the inner wall end positions of the screening box 1. A support roller 17 is installed at a position near both ends of each support shaft to support both ends of the screening cylinder 15. There are three groups of support rollers 17. An electric telescopic rod 11 is fixedly installed below the rotary power box 10. Side support seats 2 are fixedly arranged at both end positions of the screening box 1. A lower support seat 3 is arranged below the side support seat 2. The lower support seat 3 is fixedly installed on a support chassis 4.
[0025] Among them, the lower support seat 3 is designed with a telescopic buffer structure and is internally provided with a spring structure. A reinforcing rib is arranged between the side support 5 and the screening box 1 to improve the structural stability of the side support 5.
[0026] The sealing cover 7 is connected to the screening box 1 through a hinge. A fixed lock 9 is installed on the side of the sealing cover 7 away from the hinge. A lock connection seat 13 is fixedly installed on the top of the screening box 1. The position and specifications of the fixed lock 9 are adapted to be used for locking the sealing cover 7.
[0027] The main body of the screening box 1 is of a cuboid structure, and the lower part is of a conical structure. A discharge port 12 is arranged at the lower end of the conical structure to facilitate the discharge of screened materials. Rotating shafts 16 are fixedly arranged at both ends of the screening cylinder 15.
[0028] The rotating shaft 16 at one end close to the rotary power box 10 extends into the rotary power box 10. A rotating gear 18 is installed on the rotating shaft 16. A mating rack 19 is meshed on one side of the rotating gear 18. The lower end of the mating rack 19 is fixedly connected to the telescopic end of the electric telescopic rod 11.
[0029] A sliding guide sleeve 22 is arranged at the mating position of the electric telescopic rod 11 and the rotary power box 10. A lifting slider 20 is fixedly arranged on the side of the mating rack 19 away from the rotating gear 18. The lifting slider 20 is slidably connected and cooperates with a stable slide rail 21. There are multiple lifting sliders 20 to ensure the stability of the lifting movement of the mating rack 19.
[0030] The working principle of the present utility model is as follows: Open the sealing cover 7, place the telescopic feeding sleeve 14 at the opening of the feeding port 8 and the screening cylinder 15 to facilitate the addition of biological feed raw materials. After adding the raw materials, remove the telescopic feeding sleeve 14, close the sealing cover 7, and lock and seal the sealing cover 7 by the cooperation of the fixed buckle 9 and the buckle connecting seat 13. The electric telescopic rod 11 expands and contracts, and during the expansion and contraction process, it pushes the mating rack 19 to move up and down along the stable slide rail 21. Since the mating rack 19 meshes with the rotating gear 18, it drives the rotating gear 18 to rotate, and then drives the rotating shaft 16 and the screening cylinder 15 to rotate. Through the lifting stroke of the mating rack 19, the reciprocating rotation angle of the screening cylinder 15 can be controlled, and the screening of materials is realized through the reciprocating rotation of the screening cylinder 15;
[0031] Meanwhile, during the rotation and screening process of the screening cylinder 15, the vibrator 6 works to drive the entire screening box 1 to vibrate, improving the screening efficiency of the screening cylinder 15. The screened materials pass through the mesh holes on the screening cylinder 15 and are discharged from the discharge port 12. After determining that the screening is complete, adjust the lifting stroke of the mating rack 19 to increase the rotation angle of the screening cylinder 15, so that the opening of the screening cylinder 15 rotates to a downward state. Thus, during the screening process, the materials that have not passed through the screening cylinder 15 are poured out, facilitating subsequent production and processing;
[0032] In the screening box 1 of the present utility model, a screening cylinder 15 is provided. Under the action of the transmission components in the electric telescopic rod 11 and the rotary power box 10, the screening cylinder 15 can realize small-range reciprocating rotation to screen and process the feed raw materials. At the same time, a vibrator 6 is installed on the outside of the screening box 1 to realize the overall vibration of the screening box 1, effectively improving the screening efficiency and screening quality. A sealing cover 7 is provided above the screening box 1, which can seal the inside of the screening box 1 during the screening process, reducing dust overflow, being safe and environmentally friendly. A telescopic feeding sleeve 14 is provided between the opening of the screening cylinder 15 and the feeding port 8, facilitating the smooth addition of materials into the screening cylinder 15 without affecting the rotation of the screening cylinder 15 during the screening process.
[0033] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present utility model, can make some changes or modifications to the above-mentioned technical content by using the disclosed technical content as equivalent embodiments with equivalent changes. However, as long as it does not depart from the content of the technical solution of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
