Wheat impurity removing device for agricultural machinery

Abstract

The invention discloses a wheat impurity removing device for agricultural machinery, and relates to the technical field of agriculture. The wheat impurity removing device for the agricultural machinery aims to solve the problems that harvested wheat contains wheat awn, gravel and other impurities, the wheat needs to be manually raised for impurity removal, and the labor intensity is high. The wheat impurity removing device for the agricultural machinery specifically comprises a base, wherein a plurality of springs are fixedly installed at the top of the base, a box body is fixedly installed among the top ends of the springs, a feeding box is fixedly installed at the top end of the box body, a discharging pipe is fixedly installed on the side face of the box body, and a plurality of screenplates and supporting plates are fixedly installed in the box body and are alternately arranged. Wind force is generated between the screen plates and the supporting plates in the box body, bran and dust among wheat can be removed by means of the wind force, the wind blows upwards from the lower sides of the screen plates, vibration of the wheat is accelerated while impurities are removed, so thatthe impurity removing efficiency is improved, the possible blocking phenomenon of meshes of the screen plates is avoided, and the impurity removal efficiency of the device is improved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a wheat impurity removal device for agricultural machinery. Background technique [0002] Wheat is the general name of Triticum plants, the representative species is common wheat, which is a grass plant, and is a cereal crop widely planted all over the world. The caryopsis of wheat is one of the staple foods of human beings. After being ground into flour, it can be used to make bread and steamed buns. Foods such as biscuits, noodles, etc. can be made into beer, alcohol, liquor (such as vodka), or biomass fuel after fermentation. Wheat is one of the three major grains, almost all of which are used for food, and only about one-sixth is used as feed. . Mesopotamia is the earliest wheat planting area in the world, and China is one of the earliest wheat planting countries in the world. [0003] The maturity period of wheat is short. After maturity, it must be harvested immedia...

AI Technical Summary

Problems solved by technology

[0003] The maturity period of wheat is short. After maturity, it must be harvested immediately and stored in the sun. After the wheat is harvested, farmers usually dry it for a few days before storing it in the warehouse. As a result, the harvested wheat contains awns, gravel and other debris, which needs to be manually removed. It is raised to remove impurities, and the labor intensity is high
