During the operation of the weiwei peanut picker, an electric motor or diesel engine drives the machine into the peanut picking system through the feed opening or automatic feed table. The roller picker rotates and impacts to separate the peanuts from the fruit stalks. The fruit and pieces fall through the concave stone holes onto the vibrating screen. The discharge port discharges the loose fruit scattered on the vibrating screen and transfers it through the vibrating screen to the fan suction port to remove debris and select clean fruit to complete the process
