Technical Field

The invention relates to the technical field of manufacturing of rice and wheat grain combine harvesters, in particular to a conveyor belt feeding type combine harvester header.

Background

The header is located at the front end of the combine harvester and serves to harvest the crop and feed it to the threshing device, so the header is an important part of the combine harvester.

The existing combine harvester cutting table generally adopts an auger barrel to feed crops, but the cutting table has a certain accumulation phenomenon because the reel and the telescopic rake fingers of the existing combine harvester have places which can not be contacted, so that the cut crops are accumulated on the table top between the reel and the cutting table pushing and transporting device, and particularly, the crops are easy to appear when the crops are sparse and short.
