Description

Technical Field

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

[0002] With the gradual development of my country's economy, the standards of agricultural planting are getting higher and higher. In the field of agricultural planting, in order to improve the germination rate of crop planting, seeds need to be screened before sowing, and the shriveled seeds are filtered out and only full and high-quality seeds are retained, thereby increasing the germination rate after planting and reducing the problem of low germination rate caused by shriveled seeds.

[0003] The Chinese utility model patent with application number 202121346748.9 discloses a seed screening and cleaning device. After the power is turned on, the seeds are poured into the box through the feed hopper. The wind from the fan blades passes through the suction port to absorb the dust and detached cortex on the outside of the seeds, thereby making the seed shells and lighter impurities sucked into the dust collection box, further improving the efficiency of seed screening. After the seed screening is completed, the dust collection box is pulled up and taken out, thereby making it convenient to take and clean the dust collection box.

[0004] However, when using a fan to absorb the dust and cortex mixed in the seeds, the position close to the fan can play a good adsorption role, but the position far away from the fan has a poor adsorption effect on dust and impurities. At the same time, the adsorption time is related to the height from which it falls downward. When the height is low, the adsorption effect on dust and other impurities is poor, and when the height is high, it will take up a larger space, so it is not convenient to use.

[0005] A seed screening and cleaning device is proposed for this purpose. Utility Model Content
