Document Type and Number:
WIPO Patent Application WO/2022/141988
Kind Code:
A1
Abstract:
Provided is a combine harvester. A feeding port is provided in the middle of a frame (2), so that a connecting port between a crop conveying structure communicating with the frame and a header (41) is located in the position of the header (41) that is close to the middle, and crops are fed into the connecting port from two sides of the header (41) more uniformly; moreover, a scattering structure is arranged close to a grain storage assembly, and the Chinese character "几"-shaped threshing direction of a double-spiral threshing conveying system is used, such that the crops enter the middle of the front end of the harvester and are scattered out of the middle of the tail end of the harvester, and the stability of the gravity center of the combine harvester is ensured. A cleaning transmission system is arranged on an outer side of a threshing system, centralized transmission is realized, and mounting and debugging are facilitated. The whole combine harvester has a compact structure, occupies a small space, is kept stable all the time in idle operation and harvesting operation processes, has high maneuverability and has significant operation efficiency.
