Screening device for soybeans

Abstract

The invention discloses a screening device for soybeans. The screening device comprises a base, a fixing frame is fixedly installed on the upper side of the base, a connecting frame is fixedly installed on the upper side of the fixing frame, a hopper is fixedly installed in the connecting frame, a screen frame is arranged in the fixing frame, an air cylinder is fixedly installed on one side of the fixing frame, and an air rod is installed at one end of the air cylinder. According to the screening device, the air cylinder fixedly installed on one side of the fixing frame drives the screen frame to move in a reciprocating mode through the air rod, and the soybeans added into the hopper are screened; when the air cylinder drives the screen frame to move rightwards through the air rod, an ejection strip drives an ejection plate to move upwards, the ejection plate drives an arc-shaped plate to rotate upwards along a connecting shaft fixedly installed at an end of a screen plate through a rolling wheel, meanwhile, the screen plate is warped by a certain angle to prevent the soybeans in the screen frame from moving rightwards along with the screen frame when the screen frame moves rightwards, and the screen plate also plays a role in screening, so that small-particle impurities such as soil blocks are screened out.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a screening device for soybeans. Background technique [0002] Soybean is an annual herbaceous plant, the most important legume in the world, a crop whose seeds are rich in plant protein. Soybeans are most commonly used to make various soy products, extract soybean oil, brew soy sauce and extract protein. Okara, or soybeans ground into a meal, are also commonly used in livestock feed. [0003] When using soybeans to process food, in order to ensure the quality of the processed food, soybeans need to be screened to remove particles such as shriveled soybeans or mixed soil clods. There are two main screening methods for soybeans, one is manual screening One is machine screening. Manual screening is time-consuming and laborious, and the effect is not good. Machine screening often adds a certain amount of soybeans for screening. After the screening is completed, the batch is replaced, an...
