In recent year,the research and extension of the potato harvest machinery has made a great development,but at present,our machine type mainly in small type,small mating power,simple structure and is a big gap between our country and foreign country about the technology level of the equipment research,the labor intensity is still great,they are seriously hold back the potatoes industrial in order to adaptation the globe and international petition,through the prehensive research on the present potatoes harvest machinery at home and abroad,we improved the design of a new type single lined potato’s bine harvest,which integrated the digging,separation,transportation,grading,cleaning selecting,bagging(boxing)in one improved the design of the potato bine harvester,which separating device used the arc round roller device has simple structure and good separation,overe the restriction of the jitter chain and screen type separation,that in small type potatoes harvest machine and the use in viscous soil,improve the separation 3 efficiency. The grading device’s improve is mainly used the first order and the second order grading mechanism which posed of cylindrical roller and semi lunar groove had different space,realized the big,medium,small potatoes grading and transportation,greatly reduced the labor intensity and improved the product determined the whole improving design scheme,using the CAXA software built the integral threedimensional modeling and make the motion simulation to the grading deviceing the ADAMS software,analysis the all level potatoes simulated motion situation,verify the feasibility and reliability of the design and proposed the improving suggestion according to the simulation results.
