Soybean sorting machine

Abstract

The invention relates to the field of screening equipment, in particular to a soybean sorting machine. The soybean sorting machine comprises a shell, a drying mechanism and a screening mechanism, wherein the drying mechanism and the screening mechanism are arranged in the shell; the drying mechanism comprises multiple first belt conveyors, and the conveying directions of any two adjacent first belt conveyors are opposite; the screening mechanism comprises a second belt conveyor and a third belt conveyor which are arranged below the drying mechanism, a guide plate which guides soybeans which fall down through the first belt conveyor at the lowest portion to the second belt conveyor is arranged at an initial end of the second belt conveyor in the conveying direction, a gap is formed betweenthe upper edge of the guide plate and the first belt conveyor at the lowest portion, and a fan which blows the soybeans which fall down from the first belt conveyor at the lowest portion to the thirdbelt conveyor is arranged at the gap. According to the soybean sorting machine, the soybeans can be screened and graded according to the quality of the soybeans, the quality of the sorted soybeans isidentical, and the soybean sorting machine helps to raise seedlings and increase the yield.

Description

technical field [0001] The invention relates to the field of screening equipment, in particular to a soybean sorting machine. Background technique [0002] With the development of society, the renewal of science and technology, and the continuous improvement of agricultural technology, the screening and grading of various crop seeds also need continuous development. The traditional material screening system, taking soybeans as an example, uses mechanical vibration or roundness to screen. Although soybeans are screened in this way, the efficiency is relatively high, but in the screening process of this screening method, only the roundness of soybeans is used. The wholeness or the color of the material is used to distinguish the quality of the material. The roundness or color of the soybeans screened by this method is better, but the internal structure of the soybean cannot be guaranteed to be intact. For example, the inside of the soybean is bitten by insects. Incomplete, or...

The traditional material screening system, taking soybeans as an example, uses mechanical vibration or roundness to screen. Although soybeans are screened in this way, the efficiency is relatively high, but in the screening process of this screening method, only the roundness of soybeans is used. The wholeness or the color of the material is used to distinguish the quality of the material. The roundness or color of the soybeans screened by this method is better, but the internal structure of the soybean cannot be guaranteed to be intact. For example, the inside of the soybean is bitten by insects. Incomplete, or soybeans are slightly damaged externally without knowing it, and this damage cannot be distinguished by the traditional soybean screening system, which will affect the planting quality of soybeans, and then affect the success of breeding seedlings. Quality, resulting in a reduction in the production of soybeans, or affecting the quality of the food, reducing the quality of the food and reducing the income of farmers and food manufacturers
