The peanut shelling machine consists of a frame, a fan, a rotor, a motor, a screen (both large and small), a hopper, a vibrating screen, a V-belt pulley and its transmission V-belt.
After the machine is in normal operation, peanuts are put into the feeding hopper quantitatively, evenly and continuously. The peanut shells are broken under the repeated blow, friction and collision of the rotor. Peanut grains and broken peanut shells pass through a screen with a certain aperture under the rotating wind pressure and impact of the rotor (the first time peanuts are threshed, a large-hole screen is used, and the cleaned small peels are replaced with a small-hole screen for the second time). Secondary shelling), at this time, the peanut shells and grains are blown by the rotating fan, the light peanut shells are blown out of the machine, and the peanut grains are screened through the vibrating screen to achieve the purpose of cleaning.
Ⅲ. Requirements for Correct Use of Shelling Machine
1. Requirements for shelling machines.
In order to peel cleanly and have high productivity, a peeling machine with a cleaning device is also required to have a high degree of cleanliness; the loss rate must be low and the breakage rate must be small; the structure must be simple, reliable in use, easy to adjust, have low power consumption, and have Certain versatility. It can be used for shelling a variety of crops to improve the utilization rate of machinery.
2. Requirements for peanuts (skin fruits).
Peanuts should be properly dry and wet. If they are too dry, the crushing rate will be high; if they are too wet, work efficiency will be affected. The following methods can be used to ensure proper drying and wetness:
① Shelling in winter.
Before peeling, spray about 10 kilograms of warm water evenly on 50 kilograms of peeled fruit, cover it with plastic film for about 10 hours (in other seasons, cover it with plastic film for 6 hours), and then dry it in the sun for about 1 hour. Peel the shell.
② Soak the dry peanuts (peel fruits) in a large pool.
Take them out immediately after soaking and cover them with plastic film for about 1 day. Then dry them in the sun and start peeling them when they are dry and wet.
Ⅳ. Usage methods and steps.
1. Before use, check whether the fasteners are tightened, whether the rotating part is flexible, and whether there is lubricating oil in each bearing. The sheller should be placed on a stable ground.
2. After the motor is started, the rotation of the rotor should be consistent with the direction pointed on the machine. Let it idle for a few minutes and observe whether there are any abnormal noises. Only after it runs normally can you feed peanuts evenly.
3. Peanuts should be fed evenly and in an appropriate amount, and should not contain iron filings, stones and other debris to prevent breaking the peanuts and causing mechanical failure. When the peanuts cover the sieve surface, the rice outlet switch can be opened.
4. Use a suitable screen according to the size of the peanuts.
5. When the number of peanut shells in the peanuts increases, the motor can be moved downward to tighten the fan belt and increase the air blowing volume.
6. During operation, people should not stand on the side of the belt drive to avoid injury.
7. After using the machine for a period of time, when preparing to store the machine, the dust, dirt on the outside and remaining seeds and other debris inside should be removed, and the belt should be removed and stored separately. Clean each part of the bearing with diesel fuel, dry it and apply butter on it. The machine should be covered and placed in a dry warehouse to avoid sunlight and rain.
8. Make sure there is sufficient lubricating oil in the transmission parts and bearings and clean and replace them regularly.
