Abstract

The present invention provides a grain combine harvester comprising a header body, a chassis, a first bridge, a threshing chamber and threshing rollers. The header body is arranged at the front end of the chassis, the threshing chamber is arranged at the rear end of the chassis, the header body communicates with the threshing chamber by the first bridge, the threshing rollers are arranged in the threshing chamber, the first bridge is connected with the threshing rollers by a second bridge, and the first bridge is hinged to the second bridge. The grain combine harvester adopts double bridges and double threshing rollers and combines a crawler chassis to provide the grain combine harvester with large feed amount, fast harvesting speed, high efficiency of threshing and selection and good universality by reasonable layout and matching.

Description

Technical field [0001] The invention belongs to the technical field of agricultural equipment, and specifically relates to a grain combine harvester. Background technique [0002] The existing grain combine harvester mainly adopts horizontal axial flow and single vertical axial flow threshing and separating device. The horizontal axial flow threshing and separating device has a simple and compact structure and good threshing performance. However, due to the limitation of the horizontal space position, the threshing drum cannot be too long. Therefore, the threshing and separation capabilities are greatly restricted, and problems such as incomplete separation, increased entrainment loss, and uneven distribution of materials on the cleaning screen are often encountered when increasing the feed rate. The single-vertical axial flow drum has greatly improved crop threshing and separation capacity, harvesting efficiency and harvest performance compared with horizontal axial flow threshi...
