Environment-friendly grain screening machine

Abstract

The invention discloses an environment-friendly grain screening machine comprising a main body unit and a screening unit. The main body unit comprises a cylindrical shell, fixed plates, supporting legs, a first discharging pipe, a second discharging pipe, a rectangular shell, fixed blocks and a hopper. The fixed plates are perpendicularly arranged on the two sides of the cylindrical shell correspondingly, and the supporting legs are evenly arranged at the bottoms of the fixed plates. The first discharging pipe is arranged at the bottom of the cylindrical shell, the second discharging pipe is obliquely arranged on the outer side of the portion, between the fixed plate located on the left side and the first discharging pipe, of the cylindrical shell. The rectangular shell is perpendicularlyarranged on the top of the cylindrical shell. A regulation cavity and a feeding cavity are formed in the rectangular shell from left to right. The regulation cavity communicates with the inner portionof the feeding cavity and the inner portion of the cylindrical shell. The fixed blocks are arranged on the two sides of the bottom end in the regulation cavity correspondingly. The environment-friendly grain screening machine is simple in structure and low in manufacturing cost, dust can be treated during screening, and the dust is prevented from polluting the environment.

Description

technical field [0001] The invention relates to the technical field of screening, in particular to an environment-friendly grain screening machine. Background technique [0002] Grain refers to the general term for various plant seeds in cooking food, also known as "grain", which is rich in nutrients, mainly protein, vitamins, dietary fiber, fat, etc. In China, the arable land only accounts for 10% of the world, but the population accounts for 10% of the world. 22%, the food problem of more than one billion people has always been the top priority. The government attaches great importance to protecting and improving the comprehensive grain production capacity, establishing a stable commodity grain production base, and establishing a grain security system that meets China's national conditions and the requirements of a socialist market economy. The basic balance between supply and demand is not only the basic policy of the government to solve the problem of food security, but ...

Problems solved by technology

[0003] Grain screening is an important part of grain production, but most of the current grain screening equipment is open, and the screening equipment is exposed to the outside. Dust is diffused during the grain screening process, which not only pollutes the environment, but also seriously damages the operators. good health
