[0029] Working process of this utility model:

[0030] The peanut shelling machine of the utility model is described in conjunction with the accompanying drawings during its working process.

[0031] Peanuts are placed in the crushing device 4 at the top, and the power source 6 is activated to drive the power transmission mechanism 5 to work, so that the crushing rod 432 crushes the peanuts to break the shells; after the crushed peanuts are broken, the peanuts and peanut shells fall from the screen into the screening device 2 below; the attached vibrator 3 is started to make the screening device 2 vibrate continuously, and the peanuts fall from the first screen partition 22 to the second screen partition 23, and the peanut shells gather in the continuous vibration and fall from the first guide plate 222 on the front side of the first screen partition 22.

[0032] The raised design of the pressure plate surface uses the principles of physics to increase the pressure concentration of the raised part, so that when the peanuts are under pressure, the pressure is concentrated in the local area of ​​the raised part, which accelerates the shelling process and improves processing efficiency and production benefits.

[0033] The principle of bump-enhanced pressure is based on the concentration effect of the bump structure on the distributed pressure. When there are bumps on the surface of an object, it can reduce the surface area of ​​the object in contact with it, thereby concentrating the force applied to the object on a smaller area, resulting in an increase in pressure per unit area.
