Seed dust removal and impurity removal device and working method thereof

Abstract

A seed dust removal device comprises a support, a material collection part, a frictional dust removal part, a staging air separation part and a material receiving part, wherein the material collection part, the frictional dust removal part, the staging air separation part and the material receiving part are fixedly arranged on the support from top to bottom in sequence. The frictional dust removal part comprises a barrel-shaped friction cavity, and a friction cover is axially arranged inside the barrel-shaped friction cavity. The barrel-shaped friction cavity comprises a barrel wall and a funnel screen, and seed through holes penetrate through the bottom end of the funnel screen. The friction cover comprises an arc top cap and a cover wall, a friction rotating rod is fixedly arranged at the top of the arc top cap, and buffer friction layers are arranged on the inner surface of the barrel wall and the outer surface of the cover wall respectively. The staging air separation part is communicated with the frictional dust removal part through the seed through holes. The seed dust removal device achieves seed convergence and removal of dust on the surfaces of seeds through friction by ingeniously taking advantage of the sequential installation of the material collection part, the frictional dust removal part, the staging air separation part and the material receiving part, and effectively separates the seeds and dust.

Description

technical field [0001] The invention relates to a device for removing dust and impurities from seeds and a working method thereof, and belongs to the technical field of crop seed processing and storage. Background technique [0002] Plant diseases are an important cause of crop yield reduction. Some pathogenic bacteria (such as: Sclerotinia sclerotiorum) infect seed buds and seedlings by mixing among seeds and sowing, causing crop disease in the field and causing dead seedlings. For sensitive and fragile seeds, in order to avoid damage to the seeds and untimely germination, it is not advisable to rinse with water or soak the seeds with chemical reagents to avoid unnecessary losses. It is only necessary to clean the seeds during the process of seed collection and sorting. Dust handling. This can not only clean up the pathogenic bacteria mixed among the seeds, but also alleviate the damage of insect pests and molds to the seeds to a certain extent, and prolong the storage lif...

AI Technical Summary

Problems solved by technology

However, due to the various shapes of seeds and most of them are small, the dust cleaning work is cumbersome and inefficient

Manual dust removal is inefficient, labor-intensive and time-consuming. If mechanical dust removal is not handled properly, it is easy to cause damage to the seed coat and endosperm of the seeds, which will affect the quality traits, storage life and germination vitality of the seeds.
