1. Working principle of peanut shelling machine
The peanut shelling machine consists of machine body, fan, rotor, single-phase machine, sifter cloth (two types, big and small), feeding hopper, vibration sifter, V belt pulley and transmission triangle belt etc. After normal operation of the machine, the peanuts are feeding into the hopper rationally, evenly and continuously. The peanuts are crushed under the repeated hitting force, friction and collision of the rotors. The peanut kernel and crushed shells are pressed and hit by the rotating air pressure and pass through the sifter with certain aperture( big hole screen used for the first time of shelling, then the screened kernel and shell used the small hole screen for the second time of shelling), to realize the filtering and separation. The light weight peanut shell is blown out of the machine under the rotating blowing force of the fan, while the heavy weight peanut kernels are picked under the force of vibration sifter.
2. Requirement of right way of using peanut shelling machine
1). Requirement of the shelling machine
The peanut shelling machine should be equipped with the grading device with clean shelling and high production, as well as much higher clearness; lower losing rate and lower broken rate; simple structure and reliable performance, easy to adjustment, less power consumption and universal applicability. The machine can be used for many crops to improve the utilization rate of the machine.
2).Requirement for the peanut kernel and shell
The peanut has proper moisture content. If the peanut are too dry, it has high broken rate. If the peanuts are too wet, it affects the working efficiency. Several ways can be adopted to obtain the proper moisture content. 1> shelling in the winter. Before shelling, about 10 kg warm water are spread evenly on the 50kg peanut kernel and shell and covered with plastic thin film for about 10 hours( 6 hours is ok in the other seasons). Then the peanut and shell are dried under the sunshine for about 1 hour before shelling. 2> Put the drier peanut and shell in the big pond and pick up them after soaking. Then the peanuts are covered with plastic thin film for about 1 day. Then the peanut are put under the sunshine, shelling the peanut with proper moisture content.
3. The method of using and attentions
1). Please examine the fastening piece is tight or not before using, the rotating part is flexible or not, each of the bearing has enough lubrication oil or not. The peanut shelling machine should be placed on the ground steadily.
2). When the motor is on, the direction of rotor should be identical to the direction marked on the machine. Let the machine run idle for a few minutes and observe the abnormal sound. When the machine is in normal operation, the peanut are feeding into the machine evenly.
3). Feed the peanut evenly with certain amount. It is ensure that there are no iron scraps and stones in the peanut, to avoid of breaking of peanut and mechanical failure. When the peanuts are spread on the sifter surface, the discharging mouth can be opened.
4). Select the proper sifter cloth according to the size of the peanuts.
5). When the shell is increasing in the peanut kernels, the motor should be moved downward, to tighten the belt of fan and strengthen the wind force.
6). during operation, the people should not stand by the side of driving belt, to avoid of injury.
7). After a period of time of using, the machine should be removed the surface dust, dirty things and inner remained pellets or other things before preservation. The belt should be unpacked for preservation in other place.
8). It is ensures that the transmission part and the bearing has enough lubricant oil and be cleaned regularly or replaced the wearing parts.
