The working principle of the fully automatic chestnut sheller is mainly based on physical effects such as mechanical extrusion, friction, and air selection, combined with an automated control system to achieve efficient shelling. The specific process is as follows:
Power transmission system
The main drive shaft is driven by an electric motor through a belt drive, which drives the hulling roller blade and screening mechanism. The power distribution is achieved through multiple pulleys, ensuring synchronous rotation of the upper and lower rollers (fracturing shell), as well as the up and down reciprocating motion of the screening mechanism.
Core mechanism for shell removal
Roller squeezing: After entering the roller, the chestnut shell gradually breaks and falls off under the rotation of the roller and the cutting action of the roller knife.
Friction and impact: Some models use friction wheels or vibration devices to separate the shell from the nuts through continuous friction or vibration.
Screening and Separation System
Initial screening: The shelled chestnuts are separated from the outer shell and kernels by a vibrating screen or air sorting device based on particle size.
Fine screening: The small particle shell is blown out by a fan, and the nuts undergo secondary screening to ensure cleanliness.
Automated control
Real time monitoring of chestnut size, speed and other parameters through sensors and PLC systems, automatic adjustment of roller pressure, conveying speed, etc., to ensure shelling efficiency and kernel integrity.
Structural optimization
Some models adopt adjustable shell or silicone disc design to adapt to different sizes of chestnuts, avoiding damage or incomplete shelling caused by differences in fruit size.
The system integrates mechanical structure and intelligent control to achieve automated processing of chestnuts from feeding to discharging, significantly improving production efficiency and reducing labor costs.
