Novel grain cleaning equipment

Abstract

The invention discloses novel grain cleaning equipment which comprises a machine box. A feeding opening is formed in the top end of the machine box, and a hopper is welded to the feeding opening. Thelower end of the machine box is of a conic structure, a discharging opening is formed in the position of the bottom end of the machine box, and an ash pipe is welded to the discharging opening. Multiple vibration screens spaced up and down are arranged in the machine box. According to the novel grain cleaning equipment, when the condition that screen holes are blocked by materials happens, a leadscrew is lifted, so that the right sides of the vibration screens ascend, the whole vibration screens are in an inclined state, at this moment, compressed air is generated by an air compressor and issprayed out from spray pipes, the materials clamped in the screen holes are blown away from the screen holes under the action of wind power, therefore, the screen holes are dredged, and the materialsblown away from the screen holes roll out from a screening outlet; and cleaning of the vibration screens can be fast achieved as a whole, efficiency is high, and personnel are more relaxed.

Description

technical field [0001] The invention relates to the field of material processing, in particular to a novel grain cleaning equipment. Background technique [0002] Grain cleaning machine, also known as grain cleaning machine, is a kind of grain screening machinery. It relies on equipment fans and built-in vibration screening to classify, screen and remove impurities from grain and other economic crops. [0003] Grain cleaning machine, also known as grain cleaning machine, is a kind of grain screening machinery. It relies on equipment fans and built-in vibration screening to classify, screen and remove impurities from grain and other economic crops. It is suitable for cleaning and screening commercial crops such as corn, wheat, peanuts, soybeans, rice, millet, cotton seeds, and camellia seeds. [0004] The traditional method is to use vibration screening, but during the vibration screening process, materials are prone to clogging the screen holes, which requires manual cleani...
