When the threshing machine is used in actual threshing operation, the diameter of the threshing cylinder cannot be changed, so that the threshing operation interval between the threshing cylinder and the threshing concave plate which is matched with the threshing cylinder for operation is fixed, when the yield of the threshed grains is different, or the feeding amount of the threshed crops is different, the threshing quality is influenced, and the threshing machine comprises a threshing rate, a grain crushing rate, a grain recovery rate and other operation indexes. When the crop yield is low or the feeding amount is small, the operating efficiency of the threshing machine is reduced, and the operating cost is improved; when the crop yield is high or the feeding amount is large, the threshing rate and the kernel recovery rate are reduced, the kernel breakage rate is improved, and the kernel loss is caused. In order to solve the problems, the applicant has developed a threshing cylinder with adjustable diameter, and the purposes of stronger threshing operation adaptability, better threshing operation quality and higher threshing operation efficiency are achieved. However, the problems of complex structure and high manufacturing and processing cost exist in the structural design and need to be solved. Therefore, there is a need to provide agricultural users with a new configuration of variable-diameter threshing cylinders.
