One of the vulnerable parts of peanut shelling machine: rotor

Peanut shelling machine consists of a frame, a fan, a rotor, a motor, a screen, a feed hopper, a vibrating screen, a triangle pulley and its transmission tripod. After the machine runs normally, the peanuts are put into the hopper quantitatively, evenly and continuously, and the peanut shells are broken under the repeated impact, friction and collision of the rotor. Under the rotating wind pressure and impact of the rotor, peanut kernels and broken peanut shells pass through the screen with a certain aperture (large-hole screen for peanut threshing, and small peanut after cleaning is replaced by small-hole screen for secondary shelling). At this time, the peanut shells and kernels are blown out of the machine body by the blowing force of the rotating fan, and the peanut kernels are screened by a vibrating screen to achieve the purpose of cleaning.

Among all the components of peanut sheller machine, rotor is one of the vulnerable parts of the equipment. The rotor is a rotating part in the motor, and it is a device used to realize the conversion between electrical energy and mechanical energy. In the process of motor rotation, it will inevitably cause rotor wear. There are many reasons for the wear of rotor. The manifestations of wear are mainly adhesive wear, abrasive wear, fatigue wear, fretting wear, etc. Although the metal has high hardness, it has poor concession (it cannot be recovered after deformation), poor impact resistance and poor fatigue resistance.

In case of rotor wear, we mainly take the following measures:

1. Replace the rotor: When the rotor is seriously worn, it needs to be replaced with a new rotor.
2. Repair the rotor: If the rotor is not badly worn, it can be repaired to extend its service life. Repair methods include grinding, spraying, etc.
3. Adequate lubrication: Among the causes of rotor wear, insufficient lubrication is an important factor. Therefore, it is necessary to ensure that the lubrication of the rotor is always sufficient.
4. Strengthen maintenance: Regularly check the use of the motor, find problems in time and carry out maintenance, which can reduce rotor wear.

In fact, rotor wear is a common problem of all mechanical equipment. As long as the wear is solved as soon as possible, the equipment can continue to be used if other parts are fine. In the process of using peanut sheller machine, in order to minimize the wear of the rotor, it is necessary to strengthen the motor maintenance and solve the rotor wear in time. Only in this way can the machine be used more smoothly and the service life of the machine be improved.
