Description

A seed screening device for agricultural technology extension

technical field

The invention relates to the technical field of agricultural screening, in particular to a seed screening device for agricultural technology promotion.

Background technique

Seeds are the reproductive system of seed plants and play an important role in the continuation of species. Seeds are closely related to human life. In addition to grain, oil, and cotton necessary for daily life, some medicinal, seasoning, and beverages come from seeds.

Before the seeds are planted, in order to ensure the germination rate of the seeds, they need to be screened. However, most of the current seed screenings are basically manually selected and screened using sieves, which is time-consuming and labor-intensive, and the separation efficiency is low. Seed screening usually blows dry seeds out by wind force, but when seeds are selected, generally not only qualified seeds and dry seeds, but also other substances such as branch impurities, and some qualified seeds are not of high quality and are easy to be picked up. When the wind is selected, it will be blown out together with the shriveled seeds and cause waste. Some unqualified seeds will also have a gravity similar to that of qualified seeds. It is easy to enter the storage device together with qualified seeds during a deletion and use as qualified seeds.
