STUDY ON THE LOSS CONTROL SYSTEM OF WHEAT COMBINE HARVESTER

In order to reduce the harvest loss and optimize improve comprehensive performance of combine harvester, relationship between feeding quantity, drum torque, speed, loss, other factors wheat harvester is studied, functional quantity speed determined. According test data, model torque a quadratic function. For land with uniform growth, size mainly affected by forward harvester. this way, paper indirectly achieves purpose controlling harvesting machinery. The control system designed in uses compensated fuzzy PID walking vehicle through real-time detection so as comprehensively working effectively loss. results show that can efficiency compared manual wheat.
