Improved electric grain screening machine

Abstract

The invention relates to the technical field of agricultural machinery, in particular to an electric machine which can be used for carrying out screening operation on grains. The improved electric grain screening machine comprises a cylindrical machine body made of a stainless steel plate. The improved electric grain screening machine is characterized in that the top of the machine body is opened for pouring to-be-screened grains, wherein the middle of the bottom of the machine body is provided with a circular discharge hole; the side edge of the discharge hole is provided with a baffle plate; the baffle plate is connected to the bottom of the machine body through a rotary shaft; the middle position of the machine body is provided with a screen; the screen is fixed to the inner wall of the machine body through a flexible belt-shaped object; the outer side of the machine body is further provided with a motor; the rotary shaft of the motor is connected to the middle position of the bottom of the screen through a transmission rod; the inner wall of the position, below the screen, of the machine body is provided with a fan; and the position, corresponding to the machine body, at an air outlet of the fan is provided with a chaff outlet. The improved electric grain screening machine adopts the motor for driving the screen on the inner part of the screening machine to work through the transmission rod, so that the grains and the crushed chaff are separated more completely, and therefore, the screening speed is greatly increased, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an electric machine that can be used to screen grains. Background technique [0002] At present, grain processing is to remove impurities from raw materials, adjust moisture, shell, peel or grind raw materials, and finally process them into edible foods that meet different quality standards. Looking back on the past, compared with foreign developed countries, my country's processing equipment has low processing precision, low degree of mechanization and automation, resulting in generally low quality standards for processed products, coarse particle size, and fewer processed varieties. However, with the acceleration of modernization , human beings' requirements for quality of life and grain quality are constantly improving, and the development of science and technology makes the design and manufacture of grain finishing equipment imminent. Improving the mechanizatio...

Problems solved by technology

[0003] In the prior art, after the dehulling processing of grains represented by rice and wheat, since the finished grain after dehulling processing is mixed with the ground skin, further screening is required, and the ground skin is screened out from the finished grain. This is mainly a manual screening operation, which is time-consuming, labor-intensive, and has high labor costs and low efficiency.
