Aiming at the problem of automated control of high-level grain unloading mechanism in combine harvester, the mechanical structure, manual control process and circuit configuration of combine harvester were studied, mechanism structure and movement principle analysis of unloading grain and two degrees of freedom were carried out, and the problem of inefficiency of combine harvester was summarized. A high automated unloading system control system of combine harvester was put forward to operate logic of two-order optimization, the minimum number of position sensor system and the fool automated control algorithm design, the completion of the relevant hardware and software were designed and development, and Star 4 LZ-5. 0 Z crawler self-propelled full-feed combine harvester field test and operation comparison were done. The results indicate that the automatic unloading mechanism takes 5. 3 s, compared with the manual adjustment time reduced 4 times, increase unloading efficiency, and has unloading grain simple operation, and so on.
