AI Technical Summary

Technical Problem

Traditional wheat seed screening equipment is inefficient, and uneven material distribution leads to blockages, affecting screening quality and equipment maintenance costs.

Method used

The device employs a deceleration and anti-clogging mechanism, including a rotating shaft, an auxiliary shaft, a deceleration lever, and a flexible head. The rotating shaft and auxiliary shaft are driven to rotate by a drive unit, which slowly pushes the material to be evenly distributed. Combined with a vibrating motor and a dust collection device, it achieves uniform screening of materials and removal of dust.

Benefits of technology

It improves screening efficiency and quality, avoids material accumulation and blockage, ensures uniform screening of all seeds, and enhances the stability and ease of maintenance of the equipment.

Abstract

The utility model relates to the technical field of wheat seed screening, in particular to wheat seed processing and screening equipment which comprises a screening box, a first screen, a second screen, a speed reduction anti-blocking device and a moving device, a feeding port is formed in the top end of the screening box, and a feeding hopper is installed at the top end of the feeding port. The first screen is obliquely installed on the upper portion in the screening box, the high end of the first screen penetrates through the side wall of the screening box and is provided with a first vibration motor, a driving device drives a rotating shaft and an auxiliary shaft to rotate, and along with rotation of the rotating shaft and the auxiliary shaft, multiple sets of speed reduction rods fixed to the rotating shaft and the auxiliary shaft also start to rotate; the speed reduction rod and the soft head on the speed reduction rod make contact with materials, it is ensured that the materials are evenly distributed on the second screen by continuously and slowly pushing the materials to move forwards, falling wheat can pass through the second screen, the screening efficiency is ensured, and the speed reduction rod can be prevented from making direct contact with the second screen through the design of the soft head.
