Problems solved by technology

However, this traditional impurity removal device makes the labor intensity of the farmers very high; moreover, the farmers can only screen the grains bucket by bucket, and cannot screen continuously, so the screening efficiency is also very low

Abstract

The invention discloses a grain screening device. The grain screening device comprises a base (1), a hopper (2), a vertical channel (3), an inclined channel (4), a fan (5), a swing plate (6), a swing rod (7), a bracket (8) and a transmission gear (9); and the bracket (8) is fixedly connected to the base (1), and is coated with an accommodating bag (10) for accommodating impurity-removed grains. The grain screening device, provided by the invention, is low in labor intensity of peasants and high in screening efficiency.

Description

technical field [0001] The invention relates to the technical field of grain impurity removal, in particular to a device for grain screening. Background technique [0002] During the crop harvest season, farmers need to screen the dried grains to remove dust, rice husks, straw, etc. mixed in the grains, until finally the grains without impurities can be stored in the granary to go. In the traditional impurity removal process, the farmers raise the exhaust fan, and then the farmers bend down to put the dried grains into the pan, straighten their waists and lift the pan so that the pan is higher than the exhaust fan, and then put the pan The grains in the bucket fall down, and when these grains pass through the wind blown by the exhaust fan, the impurities mixed in the grains can be blown away, so that the grains are separated from the impurities. However, this traditional impurity removal device makes the labor intensity of the farmers very high; moreover, the farmers can o...
