Description

A multi-stage screening device for agricultural seeds

Technical Field

The utility model relates to the technical field of seed screening equipment, in particular to a multi-stage screening device for agricultural seeds.

Background technique

In the process of agricultural sowing, it is necessary to screen the seeds for sowing to separate sand, deformed seeds and broken seeds from high-quality seeds with full grains, so as to ensure the success rate of sowing germination, the health of the plants after germination, and the yield and quality of the crops. The screening device is a mechanical device for seed screening with a high degree of automation.

In the publication number CN211587457U, a vibrating automatic multi-stage screening device for agricultural sowing seeds is disclosed, which includes an outer box body, a driving motor, a rubber ring and an eccentric wheel. A driving motor is fixed to the bottom of the inner side of the outer box body, a screening net is installed on the inner cylinder, and a discharge window is provided on the outer box body. The vibrating automatic multi-stage screening device for agricultural sowing seeds adopts a novel horizontal rotary design, so that the device can quickly discharge the screened seeds and sand and gravel of different grades from the horizontal direction. It not only has high working efficiency, but also is not easy to be blocked, and can continuously and quickly perform screening and discharge operations. However, the above-mentioned seed screening device is only suitable for screening seeds that are easy to roll, such as soybeans. Although rice seeds will be offset to the outside through the rotation of the inner cylinder, due to the inconvenience of movement, it will either stick to the filter net at a fast speed, or be scattered from larger holes, which is easy to cause accumulation and blockage, and it is not convenient to collect the flying impurities, which is not environmentally friendly. Therefore, it is urgent to design a multi-stage screening device for agricultural seeds.
