Abstract: Cleaning device is the main equipment of soybean combine harvester for cleaning and separating threshing mixture. Its performance determines the level of cleaning operation of soybean combine harvester. There are few cleaning devices specially used for mechanical harvest of soybean in China. At present, the combine harvester mainly adopts sieve-air cleaning device. This kind of cleaning device has a low matching with soybean characteristics, which leads to a high loss rate and impurity of soybean mechanical harvesting. In this paper, the research status of soybean combine harvester cleaning device was summarized from two aspects of cleaning device and key technologies, and the advanced technology of soybean combine harvester cleaning device in the world was summarized. The deficiencies of current research on soybean combine harvester cleaning device in China were analyzed, and the trend of future soybean combine harvester cleaning device was prospected.
