【Objective 】To preferably accomplish the operation process of punching hole and planting.【Method】The 2BQHM-2 air-suction peanut mulching film and punching planter was designed and manufactured for technical issues and requirements of peanut mulching film and punching planter. Based on theoretical analysis of the working parameters of the key parts,parts＇ structural optimal design of the planter components were completed with UGNX. With the virtual prototype technology,the machine was virtual assembled,and the cavitations＇ process of motion simulation was analyzed. The rationality and usability of machine components were tested.【Result and conclusion】In the peanut growing typical region,the planter field trial showed that overall performance was relatively stable,with each component operated smoothly,and the operating indicators could meet the technical requirements better. Test results of the virtual simulation were basically consistent with the operational effects of the planter. The study has provides a theoretical basis and technical reference for further optimization design of the mulching film and punching planter.
