Abstract: In view of the problem of residual feed in the feeding channel in the feeding process of cattle and sheep farms in China, a residual feed collector was designed to replace manual collection of residual feed. The machine is mainly composed of disc brush, collecting device, conveying device, aggregate box and other components. The collection vehicle cleans the leftover material to the cleaning direction of the collection vehicle through the frontend brush, and then uses the cylindrical scraper, spiral brush roller and two sides of the winch to transport the leftover  material to the suction port, and uses the chain and scraper to transport the leftover material to the leftover box. In this study, the key parts such as the disc brush cleaning device, the spiral cylindrical brush, the spiral aggregate mechanism, the chain scraper mechanism and the hydraulic system were designed and calculated, to make sure that the rotating speed of the disc brush is 150 r/min, the rotating speed of the spiral cylindrical brush is 80 r/min, the rotating speed of the screw auger is 60 r/min, and the forward speed of the machine is 5 km/h. In the actual test, the collection rate of the leftover material is above 96%, and the average collection rate is 97%. The material collection effect is good, which meets the requirements of the pasture and verifies the correctness of the design.
