Grain screening machine capable of automatically feeding and blanking

Abstract

The invention relates to the field of screening machinery and specifically relates to a grain screening machine capable of automatically feeding and blanking. The grain screening machine comprises a large-size sundries outlet, a refined grain outlet, a vibrating screen, a motor, a pressure sensor, a pressure pump, a feeding hole, a plug, an electromagnet, an air bellow, a box and a shriveled shell, wherein the pressure pump is connected with the feeding hole and the box through an iron sheet pipeline; the pressure sensor is arranged in a reasonable position of the box; the feeding hole is connected with a grain loading position; the electromagnet is arranged at the tail end of the iron sheet pipeline; the motor is arranged on the lower part of the box; the vibrating screen is connected with the box and the air bellow; the sundries outlets, such as, the large-size sundries outlet and the shriveled shell, are arranged on the reasonable positions of the air bellow; the refined grain outlet is formed at the bottom of the air bellow; the plug is connected with a power supply. The grain screening machine can automatically feed and blank and can control the feeding amount; the screening effect and the grain quality are increased; the manpower is not wasted; the efficiency is high; the use is convenient; the grain screening machine has the advantages of simple structure, reasonable setting, low manufacturing cost, and the like.

Description

technical field [0001] The invention relates to the field of screening machinery, in particular to a grain screening machine capable of automatic feeding and cutting. Background technique [0002] In many industrial sectors such as metallurgy, coal, building materials, electric power, chemical industry and food processing, screening operation is one of the important production links, and a large number of screening machines are used. Screening machine, also known as powder sieving machine, uses the relative movement of bulk materials and the screen surface to make some particles pass through the sieve holes, and divide sand, gravel, crushed stone and other materials into different levels of vibrating screening mechanical equipment according to particle size. The particle level of sieving depends on the sieve surface, and the sieve surface is divided into three types: grate, plate sieve and mesh sieve. The grate is suitable for sieving large particle materials; the plate sie...

AI Technical Summary

Problems solved by technology

However, the ordinary grain screening machine needs manpower to manually feed the material, the feeding progress is slow, and the feeding amount cannot be effectively controlled, resulting in excessive or too low grain on the screen, and the screening effect is not ideal
