Optimization Design of Self-propelled Corn Combine Harvester

Aiming at requirement of high water content corn grain harvest，on the basis of existing mature longitudinal axial flow corn harvester machine，flexible low damage corn ear picked and conveying device was developed，threshing，separating and cleaning device were also developed.Transmission drive system was optimized.Self-propelled combined harvester for corn grain was optimized to make it suitable for corn grain harvest.
