Electrical Control Circuit Optimization on the Self-propelled Wheat Combine Harvester

In order to improve the harvesting efficiency of self-propelled wheat combined harvester, the electric control system and related lines of the harvester are optimized and analyzed based on the structure and working principle of the harvester. Through analyzing the working characteristic of the key components such as walking system and harvesting devices, it is concluded that the transfer function and realize the double closed-loop control and adjustment, taking intelligent precise speed control to join core PID algorithm control, auxiliary electrical circuit improvement and control, and join the real-time monitoring and accurate alarm equipment, which would realize the optimization of control line of the whole machine. Then through experiment harvest verification, the experiment showed that the optimized harvester main performance indexes were obviously improved, especially the harvesting efficiency is increased by 13% or so than before. The electrical control circuit optimization not only has certain feasibility, but also can provide some references for the other structural optimization and improvement of wheat combine harvester.
