A double horizontal parallel split low impact threshing separation device

Abstract

The invention provides a double-horizontal parallel-connected split-flow low-impact threshing and separation device, which includes a primary stripping feeding device, a split-flow threshing device I and a split-flow threshing device II; the exit side of the primary stripping feeding device has an AB grass outlet; the split-flow threshing device AB feeding port is provided on the inlet side of I; A outlet and B outlet are respectively opened at both ends of the outlet side of the split threshing device I; A inlet and B inlet are opened at both ends of the inlet side of the split threshing device II; the outlet side of the split threshing device II There are AB grass outlets; the cut-off drum cover of the initial feeding device includes two parts, the cut-off drum cover A and the cut-off drum cover B; the shunt drum I cover of the shunt threshing device I includes the shunt drum I cover A, split drum I cover B and split drum I cover C; the split drum II cover of split threshing device II includes split drum II cover A and split drum II cover B. The device of the invention has the characteristics of low power consumption, low crushing rate, low impact and low vibration of the threshing drum.

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
