Abstract: In order to solve the problems of high labor intensity and low efficiency in manual picking of oil peony pods, a picking device suitable for oil peony pod was designed. The control system and key components were designed and analyzed, and the working parameters of key components were determined according to the biomechanical characteristics of oil peony. With the speed of conveyor belt, the speed of plucking board, the vertical distance between plucking board and reciprocating cutter as the test factors, and the yield of fruit pod as the test index, bench tests and field tests with three factors and three levels were carried out to verify. The results showed that the order of influencing factors on pod yield was the speed of plucker, the speed of conveyor belt and the vertical distance between plucker and reciprocating cutter. Conveyor speed 1.2 m/s, rotary speed 7.2 rad/s, vertical distance between rotary plate and reciprocating cutter 0 cm is the optimal parameter combination. Based on the optimal parameter combination, the field yield of oil peony pod was 95.18%, which met the requirements of oil peony pod harvest.
