【 摘 要 】

The corn cleaning device is the most critical component of the corn harvester. It has an important relationship with the loss rate and impurity rate of corn. Therefore, it is of great significance to study the corn cleaning device and cleaning process to improve the mechanization level of corn harvest and promote the development of Agricultural Mechanization in China. In this paper, a vibratory cleaning device is designed, and the working mechanism of the device is introduced. The discrete element method is used to simulate the vibration cleaning device, and the movement status of the corn prolapse during cleaning is analyzed. The speed change of corn prolapse during cleaning is also analyzed.
