Abstract

The invention relates to a threshing separation cylinder, a threshing separation device including the threshing separation cylinder and a combine harvester. The threshing separation cylinder is provided with a spin axis and comprises an truncated cone part and a cylindrical part in an axially flowing axis AA' direction in the threshing separation device respectively, wherein the truncated cone part comprises an truncated cone main body, the small diameter end part of the truncated cone main body is at the front end part of the threshing separation cylinder, the truncated cone main body is extended from the small diameter end part along the spin axis direction, the cylindrical part is extended from the big diameter end part of the truncated cone part to the rear end of the threshing separation cylinder along the spin axis of the threshing separation cylinder, wherein helical blades and corn adjusting components are arranged on the truncated cone main body. Separating teeth including spike teeth, bar teeth, plate teeth and arch teeth are arranged on the cylindrical part.

Description

technical field [0001] The invention relates to a threshing separation drum, a threshing separation device and a combine harvester comprising the threshing separation drum Background technique [0002] The threshing separation device is the main working part on the combine harvester and thresher, which is used to remove the grain from the ear and separate the grain from the draft as much as possible. [0003] The types of threshing and separating devices are divided into full-feeding and half-feeding threshing machines are divided into two categories: full-feeding and half-feeding. The full-feed thresher feeds all the crops into the threshing and separating device, while the half-feeding thresher works, the tail of the crop stalk is clamped, and only the ear head part enters the threshing and separating device. [0004] According to the characteristics of the threshing separation device, the full-feed threshing separation device can be divided into two types: tangential flo...
