Soybean classifying screening machine

Abstract

The invention is applicable to the technical field of soybean screening, and provides a soybean classifying screening machine. The screening machine comprises a classifying screen assembly and a matching assembly, the classifying screen assembly comprises a screen drum, a feeding hopper, a discharging hopper, a partition ring, a first classifying screen, a second classifying screen and a third classifying screen, and the feeding hopper and the discharging hopper are fixedly connected to the screen drum. The feeding hopper and the discharging hopper are located on the outer side wall of the screen drum. The inclined screen drum and the feeding hopper are located at the lowest end of an inclined charging barrel so that soybeans cannot enter a next classifying screen cavity under the action of an external force in the screen drum, the soybeans are effectively prevented from freely rolling under the action of the dead weight and entering different classifying screen holes, when the soybeans pass through the classifying screens, three classifications are divided according to the sizes of the soybeans, and the machine meets the agricultural requirements, greatly improves the soybean screening efficiency, and facilitates daily eating and processing of users.

Description

technical field [0001] The invention belongs to the technical field of soybean screening, in particular to a soybean grading and screening machine. Background technique [0002] Soybeans are commonly known as soybeans. The legume soybean is an annual herb. It is cultivated all over China and is also widely cultivated all over the world. Soybean is one of the important food crops in China. It has been cultivated for 5,000 years. It was called Shu in ancient times and is the main production area in Northeast China. , is a crop whose seeds are rich in plant protein. Soybean is most commonly used to make various soy products, extract soybean oil, brew soy sauce and extract protein. [0003] The invention authorized by the notification number CN201410561311.5 is an agricultural machinery and equipment used for soybean grading and screening in agricultural production, but the agricultural machinery and equipment for soybean grading and screening in agricultural production have t...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a soybean grading and screening machine, which aims to solve the problem that there is no obvious partition between soybean grading sieves in the original agricultural machinery equipment used for soybean grading and screening in agricultural production, so that smaller soybeans cannot be guaranteed. It will not be discharged from the remaining larger grading sieve holes, resulting in incomplete grading of soybeans and confusion in grading, and does not fundamentally solve the problem of soybean grading and screening
