Abstract

The invention relates to the technical field of agricultural machinery, in particular to a combine harvester, which comprises a machine frame, a header, a conveying chute, a vibrating screen, a front threshing chamber and a back threshing chamber, wherein the front threshing chamber and the back threshing chamber are arranged on the machine frame from the front to the back. Each of the front and back threshing chambers comprises a top cover, an axial-flow drum and an escapegrid, a drum shaft is arranged in the inside of each axial-flow drum, both the drum shafts are arranged on the machine frame through bearing seats, both the front and back threshing chambers are provided with feeding ports and discharge ports, and the discharge port of the front threshing chamber is opposite to the feeding port of the back threshing chamber. The invention is characterized in that the front threshing chamber and the back threshing chamber are distributed vertically, and the front axial-flow drum and the back axial-flow drum are distributed vertically. In the invention, the flowing path of materials in the threshing chambers is more reasonable, the flowing of the materials is smoother, the threshing rate is high, the breaking rate is low, the discharging condition of straws is good, and no blockage of the straws exists in the machine.

Description

(1) Technical field: [0001] The invention relates to the technical field of agricultural machinery, in particular to a combine harvester. (two) background technology: [0002] At present, the combine harvester for harvesting crops such as rice and wheat usually only includes a spike-toothed threshing drum. The crops harvested by the header enter the threshing chamber through the conveying trough, and the spike-toothed threshing drum rotates at a high speed at the same time. Under the combined action of the sieve, the mature and plump grains fall off from the stalk. The combine harvester of this kind of structure is not ideal in terms of cleaning rate. The closest prior art Chinese patent CN02288324.X discloses the patent of the threshing device called the combine harvester for this reason, and Chinese patent 200920021696.0 discloses the patent called the double-drum rice combine harvester, and these two patents have all increased a The threshing chamber includes the spike-...
