Horizontal axial flow threshing and separation device

Abstract

The invention relates to a transverse axial flow threshing and separating device, and belongs to the field of combined harvester matching devices. The problems that an existing threshing and separating device is small in feed amount and low in efficiency are mainly solved. The transverse axial flow threshing and separating device mainly comprises a threshing roller, a 360-degree separating shell, threshing section adjustable concave plates, separating section adjustable concave plates and guide plates; wherein the threshing roller is located in the 360-degree separating shell and concentrically matched in a large-gap mode, and the threshing section adjustable concave plates and the separating section adjustable concave plates are located on the 360-degree separating shell. The threshing roller is composed of a roller body, forward rasp bars, reverse rasp bars, separating plate teeth and a straw discharging plate, the roller body is integrally welded, and the forward rasp bars, the reverse rasp bars, the separating plate teeth and the straw discharging plate are located on the roller body. 360-degree all-directional separation can be achieved, grains can be separated fast and effectively, meanwhile, the breakage rate is reduced, and the grain loss is reduced to the maximum extent.

Description

technical field [0001] The invention relates to a multifunctional transverse axial flow threshing and separation device for grain harvesting, which belongs to the field of combine harvester matching devices. Background technique [0002] The threshing and separating device is the most important working part on the combine harvester. Its main function is to remove the grain from the ear and separate the grain from other materials as much as possible. At present, according to the movement direction of the grain in the drum, it can be divided into threshing and separating devices of tangential flow type, tangential flow plus horizontal axial flow type, axial flow type, and tangential flow plus vertical axial flow type. These structures have their own applications. At present, the cutting flow plus horizontal and vertical axial flow technology is the most widely used and the largest sales in the market. The existing problems are the small feeding amount and low efficiency. Rest...
