After drying, the picking and harvesting machines are used to complete the picking, fruit picking and seedling separation processes. The recovery can effectively recover the pods and improve planting. However, manual recovery has low efficiency and high cost, and mechanical recovery can provide higher production benefits. In the process of picking up, the phenomenon of fruit drop is easy to occur, and the loss rate of peanuts is high.
