Description

Technical Field

[0001] This utility model relates to the field of vibrating screening devices, and in particular to a multi-layer high-efficiency vibrating screening device. Background Technology

[0002] Corn feed processing is the process of converting corn into feed suitable for animals. Corn kernels vary in size and shape, and vibrating screens can classify them according to kernel size. Separating corn kernels of different sizes allows for more precise processing in subsequent stages to meet different production needs.

[0003] Vibrating screens are typically powered by a vibrating motor, which contains an eccentric block. When the motor is powered on, the eccentric block rotates in a circular motion with the motor shaft. Because the center of gravity of the eccentric block does not coincide with the center of the motor shaft, centrifugal force is generated. The magnitude and direction of the centrifugal force change continuously with the rotation of the eccentric block, causing the motor to vibrate. This vibration is transmitted to the entire screen body through connecting components, causing the screen body to reciprocate. Impurities such as stones, soil, metal scraps, and straw are removed from corn through screening.

[0004] The screen plates of existing vibrating screening devices are usually installed on the screening frame by bolts. The installation of screen plates fixed by bolts is inconvenient. Therefore, a multi-layer high-efficiency vibrating screening device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-layer high-efficiency vibrating screening device, which aims to improve the problem of inconvenient installation of the screen plate in the prior art.

[0007] As a further description of the above technical solution:

[0008] The feeding assembly includes a fixed frame, the rear outer wall of which is fixedly connected to the front outer wall of the base. A feeding box is fixedly connected to the rear outer wall of the fixed frame. A motor is fixedly connected to the front of the feeding box. A rotating shaft is rotatably connected to the inner wall of the feeding box. The front inner wall of the rotating shaft is fixedly connected to the output shaft of the motor. A feeding column is fixedly connected to the outer wall of the rotating shaft.

[0009] As a further description of the above technical solution:

[0010] The limiting component includes a limiting block, the bottom end of which is elastically connected to the upper inner wall of the insertion rod by a spring.

The insert rod is inserted from the front side of the fixed column. The limiting block is squeezed by the outer wall of the fixed column, causing the limiting block to retract into the insert rod.

The rear outer wall of the fixed frame 8 is fixedly connected to the front outer wall of the base 1. The feeding box 7 is fixedly connected to the rear outer wall of the fixed frame 8. The feeding box 7 is used to hold materials such as corn. A motor 9 is fixedly connected to the front of the feeding box 7. The operation of the motor 9 drives the rotating shaft 16 to rotate.

[0033] Reference Figure 2 and Figure 3The limiting component includes a limiting block 13.
