Abstract: Based on the principles of saving materials, low cost, simple safety, and high efficiency, this thesis is based on the design and development of a rice cleaning device. The basicwork completed is as follows: Through the sampling and analysis of domestic and foreign technical surveys, it is a key component of the device. The performance basiswas provided at the levels of experiments and research. The structure of the mechanical devicewas reasonably designed after theoretical guidance, and a cleaning devicewith sleeve rollers as the mainworking componentwas designed to screen the grain. This design plan designed the sleeve-type eye roller, designed the diameter, angularvelocity and inclination of the sleeve-type sorting cylinder, and designed and calculated the required main components and checked the parameters, completed the equipment drawings and the main part design. The main design includes drive design, transmission design, etc. Through the design of eachworking part, the mechanical device is trial-produced to obtain the best test performance parameters, and then the performance of the rice cleaning device is optimized.
Keywords: sleeve roller, sorting cylinder, drive design
