Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] Such as figure 1 The cut-off combined longitudinal axial flow threshing and separating device includes a chopping device and a longitudinal axial flow threshing and separating device. The device is connected with the longitudinal axial flow threshing and separation device arranged obliquely vertically through the rotating shaft 16, and the chopping device can rotate around the rotating shaft 16 after being connected to the header.

[0030] to combine figure 2 As shown, the longitudinal axial flow threshing separation device includes a threshing drum support 40, a threshing drum lower casing 38, a guide top cover 37, a longitudinal axial flow threshing drum with a drum shaft 27, and is installed on the longitudinal axial flow threshing drum in sequence along the axial direction. Concave plate screen cloth 39 below and deliver...

Abstract

The invention discloses a cutting-off combined longitudinal axial flow threshing separation device, which comprises a chopping device and a longitudinal axial flow threshing separation device; the longitudinal axial flow threshing separation device comprises a threshing drum support, a longitudinal axial flow threshing drum with a drum shaft , a concave plate screen and a conveying auger; the chopping device includes a chopping drum frame, a chopping drum fixed on the chopping drum frame, a feeding roller assembly installed on the chopping drum frame and The feeding lower channel at the lower end of the feed roller assembly; the rotating shaft is inserted into the rotating shaft connecting rod at the rear end of the chopping drum frame, and the two ends of the rotating shaft are hinged on the threshing drum support of the longitudinal axial flow threshing separation device. The chopping device quickly cuts off the material conveyed by the header and throws it to the threshing and separating device, replacing the conveying chain rake on the traditional combine harvester. Under the action of the separation device, it is quickly conveyed, threshed and separated.

Description

technical field [0001] The invention relates to the technical field of harvesting in agricultural machinery, in particular to a cutting-off combined longitudinal axial flow threshing and separation device. Background technique [0002] The threshing and separating device is one of the core working parts of the combine harvester, and its threshing performance indicators such as cleaning rate and entrainment loss rate directly affect the performance of the combine harvester. The horizontal axial flow threshing and separation device has the disadvantages of uneven feeding, great influence of crop humidity on threshing performance, and structural size limited by the transverse size of the combine harvester. The vertical axial flow threshing and separation device has the characteristics of high drum speed, strong threshing ability, the drum is arranged along the longitudinal direction of the machine, and the length is not limited by the width of the combine harvester. The threshi...
