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 chopping-threshing combined longitudinal axial flow threshing separating device, comprising a chopping device and a longitudinal axial flow threshing separating device; the longitudinal axial flow threshing separating device comprises a threshing cylinder bracket, a longitudinal axial flow threshing cylinder with a cylinder shaft, a concave screen and a conveying auger; the chopping device comprises a chopping cylinder frame, a chopping cylinder fixed on the chopper cylinder frame, a feeding roller assembly mounted on the chopper cylinder frame, and a feeding lower channel of the lower end of the feeding roller assembly; after a rotating shaft is inserted into a rotating shaft connecting rod at the rear end part of the chopping cylinder frame, two ends of the rotating shaft are hinged to the threshing cylinder bracket of the longitudinal axial flow threshing separating device. The chopping device quickly cuts off a material conveyed by a header and throws to the threshing separating device, thus replacing a conveying chain harrow on a traditional combine harvester; the material acted by the chopping device is mostly 100-300 mm in length, and is quickly conveyed, threshed and separated under the action of the longitudinal axial flow threshing separating device.

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...
