Impurity removal device for wheat after being aired and before being warehoused

Abstract

The invention discloses an impurity removal device for wheat after being aired and before being warehoused. The impurity removal device comprises a vertical cylinder, a feed pipe, two filter plates and an exhaust fan; the feed pipe is arranged at the top of the vertical cylinder; the output end of the feed pipe stretches into the vertical cylinder; a plurality of distributing pipes with outlets facing downwards are arranged in the axial direction of the output end of the feed pipe; the two filter plates obliquely supporting at the inner wall of the vertical cylinder are arranged from the top down below the distributing pipes; the diameters of filter openings in the two filter plates are different, and impurities can be filtered fully, and can be discharged from impurity discharge doors in the side wall of the vertical cylinder; and the exhaust fan is arranged at the outer part of the vertical cylinder and can suck floating dust away. The two adopted filter plates can fully filter particle impurities in the wheat; furthermore, the exhaust fan is adopted and thus can suck away air with the floating dust, which floats in the vertical cylinder; and the dust of grain can be removed quickly after the grain is aired, so that the labor intensity of workers is lowered substantially, the working efficiency is high, and the economic benefits of an enterprise are improved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an impurity removal device used for drying wheat before entering a warehouse. Background technique [0002] In the current wheat storage, such a problem is often encountered. It is often encountered that the wheat is mixed with dust and small stones. During the falling process, the dust was blown away by the strong wind, leaving only the wheat, and then put the wheat into bags and transport it into the warehouse. This is very slow, and the work is relatively heavy. It is usually manual operation, which is difficult for continuous production. It is a waste of manpower, and the efficiency is low. It is easy to get tired if people do some repetitive things for a long time. If the wheat is mixed with dust, it is unhygienic for people to eat wheat. It is very troublesome to encounter such a job.

Problems solved by technology

[0002] In the current wheat storage, such a problem is often encountered. It is often encountered that the wheat is mixed with dust and small stones. During the falling process, the dust was blown away by the strong wind, and only the wheat was left, and then the wheat was put into bags and transported into the warehouse, which was very slow, and the work was relatively heavy. It was usually done manually, which was difficult for continuous production. It is a waste of manpower, and the efficiency is low. Manually doing certain repetitive things for a long time is prone to fatigue. If the wheat is mixed with dust, it is unhygienic for people to eat wheat. It is very troublesome to encounter such a job.
