Abstract: Aiming at the problems of low mechanization level, high labor intensity and low efficiency of strawberry transplanting, a strawberry transplanter with high ridging and man-machine cooperation was designed. The whole machine is mainly composed of electric chassis, hole drilling mechanism, steering mechanism and control system. The chassis adopts the design scheme of front wheel steering, rear wheel drive and constant speed control chassis of DC brushless motor. The directional planting of strawberries adopts the design scheme of double row hole drilling with crank slider, manual seedling picking and identifying the direction of the bow back of the seedlings, and then putting the seedlings into the holes and covering the soil. Based on the multi-body system dynamics simulation software RecurDyn, the kinematics simulation analysis of the punching mechanism is carried out, and the end velocity, displacement and acceleration curves of the punching device are obtained; The strawberry bare root seedlings were cultivated for about 8 weeks. The field experiment was carried out with the missing planting rate, buried seedling rate, exposed seedling rate, transplanting qualified rate, variation coefficient of plant spacing and qualified rate of plant spacing under different plant spacing as the evaluation indexes. The test results show that when the planting efficiency is 15 plants/min· row^-1 and the plant spacing is 150mm, 200mm and 250mm, the variation coefficient of plant spacing, missed planting rate, buried seedling rate and exposed seedling rate are less than 5%, the qualified rate of plant spacing is more than 95%, and the qualified rate of transplanting is more than 90%, which meets the industry standard. The operation efficiency and planting quality are about 3 times higher than that of manual planting.
