Abstract

The invention provides a combine harvester. A feeding port is formed in the middle of a frame, so that a connecting port between a crop conveying structure communicated with the feeding port and a header is located at the position, close to the middle, of the header, and crops are fed into the connecting port from the two sides of the header more evenly; and meanwhile, a scattering structure is arranged close to a grain storage assembly, the crops enter from the middle of the front end of the harvester and are partially scattered out from the middle of the tail end of the harvester through the n-shaped threshing direction of a double-helix threshing conveying system, and the stability of the gravity center of the combine harvester is guaranteed. A cleaning transmission system is arranged at the outer side of a threshing system, centralized transmission is achieved, and installation and debug are convenient. The whole harvester is compact in structure, small in occupied space, high in maneuverability and remarkable in operation efficiency, and the gravity center is always kept stable in the empty operation and harvesting operation process.

Description

technical field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a combine harvester. Background technique

[0002] The crawler combine harvester threshing system can be divided into longitudinal axial flow threshing and cleaning system and horizontal axial flow threshing and cleaning system. These two types of threshing and cleaning systems are the main structural forms currently used in the market.

[0003] The length of the vertical axial flow drum is longer, allowing the crops to have time to fully thresh and separate in the drum, but if the length is too long, the length of the entire machine will inevitably be lengthened, the structure is not compact enough, the machine is not flexible enough when operating or turning, and the maneuverability is poor. , low operating efficiency.

[0004] The horizontal axial flow drum mainly includes a single drum horizontal axial flow threshing system and a 1.5 drum horizontal axial flow...
