Flexible-stripping and pressure-friction type soybean breeding thresher

Abstract

The invention relates to a flexible-stripping and pressure-friction type soybean breeding thresher and belongs to agricultural machinery. The thresher is mainly composed of a clamping conveying device, a stripping device, a pressure-friction threshing roller, a rethreshing roller, a transverse conveying device, a flexible spring support, a dust-collecting and impurity-removing fan, a material collecting port, a flow seed tank, a gearbox and a conventional transmission component and the like. The thresher performs segmented compound type separation and threshing operation on soybean plants to avoid the crushing of stalks of the soybean plants, and thus the problems of grain crushing, entrainment loss rise and varietal complexity and the like caused by complex structure of a cleaning deviceresulting from the similarity of the characteristics of soybean materials are solved. The thresher can complete operations of threshing, rethreshing, separation and cleaning and the like of soybean plants in one time. The whole thresher has no blind corner, the threshing of many varieties does not need cleaning, flexible part pressure-friction type bionic threshing is adopted in the whole production process, and the damage to seeds caused by hard blows does not occur. The thresher can meet the requirements of scientific research for precision and efficiency of the soybean breeding threshing process.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and mainly relates to a flexible picking-off, pressure-friction type soybean breeding thresher. Background technique [0002] Threshing and yield measurement of soybean breeding go through three steps: threshing, separation and cleaning. Traditional breeding threshers use threshing parts to beat and thresh soybean plants. The broken rate is high, and the soybean stalks are severely broken, which leads to an increase in the subsequent separation and cleaning load. The separation and cleaning devices mostly use fans and reciprocating The vibrating screen is used for separation and cleaning. These parts have complex structures and large volumes. They vibrate violently and make noise during operation, which will cause broken grains and increased entrainment losses. At the same time, the entire threshing, separation, and cleaning system is closed. It often causes multi-variety mixing phenomenon....

Problems solved by technology

Traditional breeding threshers use threshing parts to beat and thresh soybean plants. The broken rate is high, and the soybean stalks are severely broken, which leads to an increase in the subsequent separation and cleaning load. The separation and cleaning devices mostly use fans and reciprocating The vibrating screen is used for separation and cleaning. These parts have complex structures and large volumes. They vibrate violently and make noise during operation, which will cause broken grains and increased entrainment losses. At the same time, the entire threshing, separation, and cleaning system is closed. It often causes the phenomenon of multi-variety mixing. When multi-variety is threshing, it is easy to mix, and the machine needs to be cleaned separately. The operation efficiency is low, and it cannot meet the requirements of soybean yield measurement and soybean breeding in scientific research.
