Design principle and analyses of the motioncharacteristics of4H-2type peanut harvesterShang Shuqi,Wang Jiangang,Wang Fangyan,Liu Shuguang,Jiang Yuanzhi(EngineeringSchool,LaiyangAgricultural University,Laiyang,Shandong265200,China)Abstract: The structure, working principle and design of main parts of the 4H-2 type peanut harvester were described andanalyzed, and the kinematics model of the main work parts was founded. On the basis of the optimized structure, therepresentative tracks of
