Abstract: In view of the low efficiency and quality of threshing system of combine harvester in China, this paper discussed the research status of grain combine threshing system from the aspects of overall structure of threshing system, design of key parts, power consumption of threshing system and theoretical analysis of threshing process. At present, there are many combine harvesters employing axialflow threshing system. The research mainly focuses on improving the adjustability of operating parameters of the threshing system, designing flexible threshing parts, theoretical analysis of working process of the threshing system and intelligent threshing, etc. Based on this, the development trend of the threshing system is analyzed. The future research on the flexible threshing system and the threshing system with adjustable threshing intensity will further reduce the loss rate of the threshing system. The operation efficiency will be further improved, the adaptability of the threshing system to crops will be further improved, the research on special threshing parts for different crops will be further deepened, the intelligence level of the threshing system will continue to be improved, and the operation information sensing ability and intelligent control level of the threshing system will be further improved.

Key words: grain combine harvester, threshing system, intelligent
