The cleaning device in modern agricultural equipment is an important part of the reference of the grain combine harvester. The loss rate of the grain and other factors are directly affected by the cleaning device. In this paper, the development status of the current cleaning equipment and the research and analysis are described in three aspects: the distribution of the airflow field in the cleaning device, the movement law of the exudate, and the research on the centrifugal fan. The loss rate and the impurity ratio of the grain harvest are reduced. Objectives, reviewed the research status and trends of domestic and foreign grain combine harvester cleaning equipment, and put forward new ideas for the future development prospects and prospects of grain combine harvester, and provide reference for improving the research and design of grain harvester cleaning equipment. experiments.
