Design and Experiment of an Integrated Automatic Transplanting Mechanism for Picking and Planting Pepper Hole Tray Seedlings

The operation of the semi-automatic pepper pot seedling transplanter has problem a low frequency manual operation. We designed new automatic transplanting mechanism based on clamping stem. Through movement law double-crank connecting rod mechanism, static trajectory beak shape and dynamic N were to meet requirements backward transplanting. kinematics equation picking was established parameter optimization program developed MATLAB. effect changes analyzed. A group combinations that met planting optimized. After optimization, height 220.8 mm, angle 21.03° 64.15°. plant spacing 260 which meets agronomic combination theoretical analysis prototype tests, test results showed basically consistent with actual trajectory, verifying feasibility design. In this study, seedlings in suitable period 60 days selected planted at rotation speed 60, 70 80 r/min, respectively. success rate selection more than 91.1%, 78.5%, qualified erect degree 94.9%, coefficient variation stable below 14.1%. show integrated for effective.
