Peanut picking machine is a device for picking peanut pods from peanut vines and then separating and cleaning the vines. According to the feeding mode, it can be divided into full feeding type and half feeding type; According to the way of working power, it can be divided into simple hand-operated peanut picker machine, peanut picker machine matched with engine (motor) and peanut picker machine matched with tractor, etc.

Main structure of peanut picking machine:

Peanut picking machine is mainly composed of feed inlet, frame, motor, transmission part, fruit picking and separating part, fan, vibrating screen, roller and bottom screen.

Working principle of peanut picking machine:

During operation, the motor or diesel engine drives the machine to run. Under the action of the thrust generated by the pushing of people and the rotation of the roller, peanut seedlings are grabbed by the nail teeth on the roller and enter the roller. Because of the rubbing impact of the roller, peanuts fall off the stems inside the roller, and then go down to the separation chamber under the operation of gravity and centrifugal force. At the same time, most of the stalks are pushed to the outlet by axial force and discharged. After entering the separation chamber, peanuts, other sundries, dust, etc. are blown out of the machine when passing through the fan mouth, while peanuts fall on the vibrating screen, and then are separated for the second time under the action of the vibrating screen, and a small part of dust and sundries fall below the vibrating screen, while peanuts are sent to the outlet for storage.

Precautions for use of peanut picking machine:

1, In the process of use, pay attention to the various transmission parts, pulleys, etc. can operate normally, and see if there is any collision and friction. Whether the V-belt tension of transmission parts is reasonable, the motor can run normally, and whether there is electric leakage in the wiring parts, the machine can be started only after the complete overhaul of idle running.
2, During use, the operation shall be carried out according to the operation procedures. Operators should feed peanut seedlings in a safe range, with the vines facing outward and the fruits put into the entrance. It is forbidden to overload the machine, and cut off the power supply for maintenance in time under the condition of abnormal occurrence.

3, After the work is finished, the materials in the machine should be cleaned up, all transmission parts should be lubricated, and the defective parts should be welded in time. Only by doing daily maintenance can the service life of the equipment be prolonged.

The peanut picking machine has the advantages of convenient operation, reliable performance, clean picking effect, high efficiency and low breakage rate. Its appearance and use greatly improved the efficiency of peanut picking and liberated the labor force. It must be said that the peanut picker is an indispensable good helper for peanut growers.
