Design of a Small Self-propelled Potato Pickup Machine

Abstract: In view of the situation that the potatoes need to be picked up manually in the segmented harvest, a small self-propelled potato pickup machine that can replace picking potatoes by hand is designed. In this paper, we analyze the influence of structural parameters such as the picking device and conveying device of potato pickup machine on the picking effect; then we use the DEM software to simulate the picking process and conveying process; finally, we choose the optimal structural parameters. The machine is driven by a motor, with a high pickup rate, fast operation speed, compact structure, and lightweight, which is suitable for small plots of planting in hilly areas in the southwest of China.
