[0002] The inclined conveying device of the grain harvester is the first conveying device of the grain harvester. It is located between the cutting table and the axial flow threshing system of the grain harvester. It is mainly responsible for conveying crops such as corn and soybeans on the cutting table to the axial flow threshing system for threshing. Most of the inclined conveying devices of grain harvesters on the market have the following defects: (1) They do not have feeding rollers and have poor feeding capacity, which easily causes crop accumulation at the connection between the inclined conveying device and the axial flow feeding port, and repeated wear and tear of grains causes grain damage.

The above problems directly affect the overall harvesting efficiency of the grain harvester, prolong the operation time, and also reduce the income of farmers. Utility Model Content
