Description

Technical Field

[0001] The utility model relates to the technical field of seed processing, in particular to a rapeseed seed screening device. Background Art

[0002] Seeds are the basis of agricultural production, and their quality directly affects the yield and quality of crops. As an important oil crop, the purity and quality of rapeseed seeds are crucial to the development of rapeseed cultivation. Therefore, the development of efficient and accurate rapeseed seed screening equipment is of great significance to improving the quality of rapeseed seeds and ensuring the smooth progress of agricultural production.

[0003] During the processing of rapeseed seeds, they need to undergo strict screening to remove impurities (such as stones, soil, residual straw, etc.) and unqualified grains (such as shriveled, damaged, and disease-infected rapeseed). Traditional screening methods often use simple mechanical vibrating screens or manual screening. Due to their large weight and volume, they are easy to get stuck in the sieve holes or cause the screen to be blocked during the screening process, which leads to reduced screening efficiency. In addition, the operation is cumbersome and has low applicability. Utility Model Content
