Design and experimental study of ginkgo leaf picking device

To achieve the purpose of Ginkgo biloba leaves continuous harvesting, a ginkgo leaf picking device is designed. The device is consisted of a picking executive composed from a round rod picking hand and a rotating drum, a frame, a motor, a motor base, a coupling, a bearing seat, a motor support frame, a deciduous box, and a connecting screw. And the picking theoretical analysis and calculation are carried out. Finally, the feasibility of the design is verified by adjusting the tilt angle and motor speed of the picking device. The experimental results show that when the inclination angle between the picking device and the horizontal plane is 30 degrees and the motor speed is 120 r/min, the damage rate of Ginkgo biloba leaves is 1.52%. The net collection rate is 94.29%, and the damage degree of branch and stem is mild.
