Dual-transverse parallel diverting low impact threshing separator

Abstract

The invention provides a dual-transverse parallel diverting low impact threshing separator comprising a primary threshing feeding unit, a diverting threshing unit I, and a diverting threshing unit II; the outlet of the primary threshing feeding unit is provided with A B grass exits; the inlet of the diverting threshing unit I is provided with A B feeding ports; two ends of the outlet of the diverting threshing unit I are respectively provided with an A exit and a B exit; two ends of the inlet of the diverting threshing unit II are provided with an A inlet and a B inlet; the outlet of the diverting threshing unit II is provided with A B grass exits; a flow cutting roller cover plate of the primary threshing feeding unit comprises a flow cutting roller cover plate A portion and a flow cutting roller cover plate B portion; diverting roller I cover plates of the diverting threshing unit I comprise a diverting roller I cover plate A, a diverting roller I cover plate B and a diverting roller I cover plate C; diverting roller II cover plates of the diverting threshing unit II comprise a diverting roller II cover plate A and a diverting roller II cover plate B. The dual-transverse parallel diverting low impact threshing separator is small in power consumption, low in broken rate, low in threshing roller impact, and low in vibration.

Description

technical field [0001] The invention belongs to the field of combine harvester threshing and separating devices, and in particular relates to a double-horizontal parallel split-flow low-impact threshing and separating device. Background technique [0002] The threshing and separation system is the core working part of the combine harvester, and its threshing performance directly determines the working performance of the whole machine. In terms of rice threshing, threshing structures such as longitudinal flow threshing devices, transverse axial flow threshing devices, and cutting and longitudinal flow combined threshing devices have been developed at home and abroad; patent CN201280048847.6 invented a threshing device that lengthens and separates materials, greatly The threshing process and threshing time of crops have been greatly improved; the patent CN201110298025.0 invented a half-feed threshing separation device, which only threshed rice ears, and the stems were not fed ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the disadvantages of large power consumption, high crushing rate, large impact and large vibration of the threshing drums in the existing multi-drum detachment process in the prior art, the present invention provides a double-horizontal parallel shunt low-impact threshing separation device. After the initial threshing of the rice with a weight of 6-8kg / s, it is re-threshed by the split threshing device I and the split threshing device II, and finally the stems after the split threshing are crushed and sprinkled by the grass crushing device to achieve power consumption and crushing rate. , Shock and vibration reduction of the threshing drum
