In this paper,mainly according to the selection of sugar cane seeds and the quality requirements for cutting,we design a cutting mechanism not only to cut off the sugar cane,but also can ensure the cutting sugarcane planting to achieve the agronomic requirements for sugar cane.The institution's overall ideas are as follows:first,measure different kinds of sugar cane planting in different cutting force and cutting speed in case of broken head.After preliminary analysis,gain cutting force,cutting speed,the diameter of sugar cane,the species of sugar cane,cutting blade edge angle,cutting angle and cutting mode correlation.Then select the power transfer device and the working parts of the disk and blade according to the obtained data.Last design drive of belt wheel,drive shaft,bearing type,bearing cover through calculation and checking.The successful design and development of the institution of sugar cane cutting mechanism will be able to greatly reduce the labor intensity and production costs in the process of sugarcane planting.
