Abstract

The invention relates to a longitudinal axial flow threshing and separating unit which comprises an auxiliary feeding threshing unit and a longitudinal axial flow threshing and separating unit; the auxiliary feeding threshing unit consists of an auxiliary feeding threshing cylinder 2, an upper cover plate 1 and a punching concave plate 8. The longitudinal axial flow threshing and separating unit consists of a dome 3, a feeding auger 4, a top cover 5, a longitudinal axial flow threshing and separating cylinder 6 and a separating concave plate 7. The longitudinal axial flow threshing and separating unit integrates the functions of the shear flow threshing unit and the auxiliary feeding device of a traditional longitudinal axial flow threshing and separating unit, is applicable to crops with quite large feed quantity, has the advantages of even and smooth feeding, low price, simple structure and small size, and is easier to be deployed on medium- and small-sized harvesters accepted by most markets of our country.

Description

technical field [0001] The invention relates to a threshing and separating device of a harvesting machine, more specifically, the invention relates to a longitudinal axial flow threshing and separating device. Background technique [0002] The existing vertical axial flow combine harvester generally adopts a combined tangential flow and longitudinal axial flow threshing and separation device, including a tangential flow threshing device, an auxiliary feeding device and a longitudinal axial flow separation device. Cutting flow threshing devices mostly use nail-toothed drums, and the grain damage rate is high when harvesting rice, especially high-yield rice, and consumes a lot of power. Chinese patent ZL 03250419.5 discloses the control and combination device of tangential flow variable longitudinal axial flow and the auxiliary feeding device in the combined tangential flow and longitudinal axial flow threshing separation device disclosed in Chinese patent ZL 00137715.9 consis...
