Description

Technical Field

[0001] The utility model relates to the technical field of feed processing, in particular to a multi-level screening mechanism for feed particles. Background Art

[0002] Feed is a general term for food for raising animals, mainly referring to food for agricultural or animal husbandry animals. The main raw materials of feed include soybeans, corn, fish meal, amino acids, additives, whey powder, oil, meat and bone meal, grains and sorghum, etc.

[0003] Straw feed mainly refers to fibrous feed made from crushed sweet sorghum, corn, reed, cotton and other straws. It is the main feed for ruminants. In the production process of straw feed, the granular feed after granulation often has different particle sizes. Therefore, it is necessary to screen the granular feed according to different feed usage methods to obtain feed particles of the required particle size.

[0004] The existing multi-stage screening mechanism for feed particles cannot guide and disperse the granular feed when in use, which will cause the granular feed to accumulate during the screening process, thereby reducing the efficiency of the multi-stage screening. Utility Model Content

[0005] In view of the above problems, the purpose of the utility model is to provide a multi-stage screening mechanism for feed particles, so as to solve the problem that the granular feed cannot be guided and dispersed, which will cause the accumulation of granular feed during the screening process and thus reduce the efficiency of the multi-stage screening. Through the setting of the guide table, when the arc-shaped rotation of the feed particles increases the falling time of the feed particles, a part of them will be separated from the guide table when diffusing, and then diffuse and fall with the guide table as the touch point, thereby preventing the feed particles from accumulating on the first sub-screen during the falling process.

[0006] To achieve the above objectives, the utility model adopts the following technical solution: a multi-stage screening mechanism for feed particles, comprising a tank assembly, a screening assembly, and a material guiding assembly, the tank assembly comprising a screening tank barrel, the screening assembly comprising a screening inner barrel, the material guiding assembly comprising a motor, the lower end of the screening tank barrel is connected with a discharge port, one end of the screening tank barrel is connected with a first screening port, an end of the screening tank barrel away from the first screening port is connected with a second screening port, the outer wall of the upper portion of the screening tank barrel is connected with a connecting frame, a stabilizing platform is provided on the inner side of the screening inner barrel, a mounting clamp is connected on the outer wall of the upper portion of the stabilizing platform, a material guiding platform is connected to the bottom of the stabilizing platform, the inner wall of the screening inner barrel is connected with a material guiding ring plate, the output end of the motor is connected with a linkage shaft, the outer ring of the linkage shaft is connected with a first screening mesh, the inner side of the screening inner barrel is provided with a second screening mesh, and the inner wall of the screening inner barrel is connected with a supporting chassis.

[0007] The beneficial effects of the utility model are as follows: through the setting of the guide table, when the arc-shaped rotation of the feed particles increases the falling time of the feed particles, a part of them is far away from the obstruction of the guide table when diffusing, and then diffuses and falls with the guide table as the touch point, thereby avoiding the accumulation of feed particles on the first sub-screen in the process of falling; when the linkage shaft is driven by the motor to rotate, the linkage shaft drives the second sub-screen to rotate synchronously during the rotation, and then the rotation of the second sub-screen is used to screen the feed particles located thereon, wherein the feed particles that cannot pass through the aperture of the second sub-screen are discharged through the second sub-screen opening and collected centrally, thereby realizing the secondary screening of the feed particles, and the feed particles that can pass through the aperture of the second sub-screen fall downward, and then are discharged through the discharge opening and collected centrally, thereby realizing the tertiary screening of the feed particles.

[0008] To install and fix the stabilizing table:

[0009] As a further improvement of the above technical solution: a supporting foot is arranged at the lower end of the screening tank, and there are four connecting frames in total and they are connected to the outer wall of the peripheral surface of the mounting clamp ring.

[0014] In order to achieve the guided dispersion of raw materials through the guide ring plate:

[0015] As a further improvement of the above technical solution: the motor is arranged on the inner side of the stabilizing platform.

[0016] The beneficial effect of this improvement is that when feed particles are put into the inner cylinder of the screening material, the feed particles are blocked by the guide ring plate during the falling process and then diffused, and a part of the raw materials rotate in an arc with the center of the mounting clamp ring as the center of the circle, and the arc rotation of the feed particles increases the falling time of the feed particles, and then the guide ring plate is used to guide and disperse the raw materials.

[0018] As a further improvement of the above technical solution: the material guiding platform is a truncated cone-shaped structure, and the upper and lower ends of the material guiding platform are open and hollow.

[0019] The beneficial effect of this improvement is that through the setting of the guide table, the arc-shaped rotation of the feed particles increases the falling time of the feed particles, and at the same time, a part of the feed particles are blocked by the guide table when diffusing, and then diffuse and fall with the guide table as the touch point, thereby avoiding the feed particles from accumulating on the first sub-sieve during the falling process.

[0021] As a further improvement of the above technical solution: the motor is electrically connected to the operation panel, and the end of the linkage shaft away from the motor passes through the first sub-screen and the second sub-screen and extends to be rotatably connected to the supporting chassis.

[0022] The beneficial effect of this improvement is that after the motor is started, the motor starts working and drives the synchronous rotation of the linkage shaft, which is then used to drive the rotation of the first sub-screen and the second sub-screen to achieve the screening of feed particles.

[0023] In order to discharge the feed particles that cannot pass through the aperture of the first sub-sieve through the first sub-sieve opening and collect them centrally:

[0024] As a further improvement of the above technical solution: the top cross-section of the supporting chassis is a cross-shaped structure, and one end of the first sub-screen opening penetrates the wall of the screening material inner cylinder and extends to communicate with the inner cavity of the screening material inner cylinder.

[0025] The beneficial effect of the present improvement is that when the linkage shaft rotates driven by the motor, the linkage shaft drives the first sub-screen to rotate synchronously during the rotation, and then the rotation of the first sub-screen is used to screen the feed particles thereon, wherein the feed particles that can pass through the aperture of the first sub-screen fall downward, and the feed particles that cannot pass through the aperture of the first sub-screen are discharged through the first sub-screen opening and collected collectively, thereby realizing the primary screening of the feed particles.
