Design of Feeding Hydraulic Reversal Mechanism of Self-propelled Forage Harvester Based on TRIZ Theory

In view of current problems of feed blockage and low harvesting efficiency caused by poor cutting during green feed harvesting process，the TRIZ theory was used to carry out innovative design research on the feeding part of the self-propelled green feeding machine.Finally，a green feeding machine with reasonable structure and convenient operation was designed to feed hydraulic reversing mechanism，which solved feeding blockage and improved working efficiency.
