Problems solved by technology

[0002] Seeds need to be screened before sowing to remove impurities and shriveled seeds in the seeds, but the screening effect of the currently used seed screening devices is not good, the screening efficiency is low, and the dust and dust in the seeds cannot be completely removed. Seed shells and shriveled seeds lead to poor screening quality, and often need to be screened repeatedly, which is time-consuming and labor-intensive

Abstract

The invention discloses a seed screening device for agricultural planting. The seed screening device comprises a box body and a seed screening assembly arranged in the box body, wherein the seed screening assembly comprises an air separation assembly and a water selection assembly, the air separation assembly comprises a material guiding plate and an air blower, an air outlet is aslant formed in the top of the material guiding plate and is bent, the bent portion in the middle is slant upwards, an opening is formed in the top of the box body and is fixedly provided with an exhaust fan, a dust storage bin is fixedly installed at the upper portion of the side wall of the box body and communicates with the dust outlet end of the exhaust fan through a guide pipe, and to-be-screened seeds are firstly subject to air separation through the air separation assembly and are furthermore screened through the water separation assembly. In this way, the seed screening device has a good screening effect on the seeds, the screening efficiency is high, and dust, seed hulls, withered seeds and other impurities existing in the seeds can be thoroughly removed.

Description

technical field [0001] The invention relates to a screening device, in particular to a seed screening device for agricultural planting. Background technique [0002] Seeds need to be screened before sowing to remove impurities and shriveled seeds in the seeds, but the screening effect of the currently used seed screening devices is not good, the screening efficiency is low, and the dust and dust in the seeds cannot be completely removed. Seed shells and shriveled seeds lead to poor screening quality, and often need to be screened repeatedly, which is time-consuming and laborious. Contents of the invention [0003] The object of the present invention is to provide a seed screening device for agricultural planting to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A seed screening device for agricultural planting, including a box body and...
