Design and Test of a Mechanical Device for the Manipulator of the Watermelon Picking Machine

This Paper designs a mechanical device for the manipulator of the watermelon picking machine against the low mechanical degree of watermelon picking machine. The mechanical device utilizes a mechanical arm to drive the end effector to run and the end effector is responsible for clamping and shearing watermelon vines, which avoids vine disturbance and sorts out vines to be easily cut down through the process design of clamping, promoting, and re-shearing. In addition, this Paper applies Pro/E modeling, finite element analysis, and simulation analysis to complete the 3D model design of the mechanical device and transforms the 3D model into 2D drawings in Auto CAD to complete the manufacturing and assembly of the manipulator, and the test result verifies the mechanical device may realize the reliable picking of watermelons.
