Abstract

The invention provides a high-yield grain winnowing machine. The high-yield grain winnowing machine comprises a grain storage device, awn removing rollers, a grain discharging system, a winnowing box,a dust removing system and a grain discharging funnel. The winnowing machine is characterized in that the grain discharging system comprises grain discharging rollers; the winnowing box comprises a grain flow control system, an air homogenization box, an air suction box and an external frame; the air homogenization box is provided with an air inlet A and an air outlet B; a grain separation plateis arranged between the air homogenization box and the air suction box for separating grains and impurities; the dust removing system comprises a fan, a cyclone dust collector, an air lock and a screw conveyor; the fan comprises an air inlet C and an air outlet D; and the lower end of the grain discharging funnel is provided with a gravity type movable door used for discharging winnowed grains. The high-yield grain winnowing machine is simple in structure, convenient to operate, good in impurity separation effect, light in dust pollution, compact in structure and high in yield, solves the problems of poor impurity removal effect and low yield of existing grain impurity removal equipment, and has good application prospect.

Description

technical field [0001] The invention belongs to the technical field of grain processing machinery, and in particular relates to a high-yield grain winnowing machine. Background technique [0002] Wind separation is the use of wind to sort materials to achieve the purpose of removing impurities. It is a method of removing impurities through the action of air flow by using the difference in the aerodynamic properties of materials and impurities. According to the direction of winnowing airflow, it is generally divided into three ways: horizontal, vertical and oblique airflow. The cleaning machines for grain before storage in domestic grain depots mainly include cylinder preliminary cleaning sieves, specific gravity cleaning machines, vibrating negative pressure cleaning machines, etc. [0003] The disadvantages of existing equipment are as follows: [0004] 1. The working principle of the cylinder primary cleaning screen is: the grain enters the rotatable double-layer screen...
