Design on Full-Hydraulic Drive System of Corn Combine Harvester

In order to study the corn combine harvester hydraulic drive system, the hydraulic system was designed, which mainly consists of two valve blocks, eight branch circuits and other components, mainly for cutting device, snapping roll device, raking and conveying device, Transverse transport device, husker device and straw stacking device. And select the appropriate pump the hydraulic system, through the design shows that the system can complete functions, such as cutting, snapping roll, raking and conveying, Transverse transport, husker and straw stacking. One-way throttle valve was selected for MK10G1.2 / 2, Manual valve was chosen for 4WMM10J / F, and double vane pump was chosen for PFED-5141150/085. These circuits were connected in parallel among all systems, and the return line directly back to the tank. Provides the trial basis for the corn combine harvester machine.
