The Electrical Control System for The Automatic Plug-seedling Feeding Device of Pepper Transplanting Machine Based on Arduino

To address the issue of manually placing plug-seedlings into the seedling feeding mechanism in current pepper transplanting machines, and considering the high cost of electromechanical systems, this paper presents a design for an automatic plug-seedling feeding and plug-seedling cell feeding system based on Arduino. The system employs three stepper motors and thirteen cylinders working in coordination to achieve automatic plug-seedling transportation and synchronized plug-seedling cell feeding. Using the Arduino IDE, a control program was developed, and an electrical control system was constructed, followed by plug-seedling delivery experiments. The experimental results indicate that when the plug-seedling carrier is inclined at 35°, the delivery success rate reaches 93.74%. The system is reliable and stable, offering new ideas for future automation control.
