A variable rate fertilizer application system with ARM microprocessor as control core was developed. The structure and realization principle of the system were introduced. The system consists of two velocity sensors of photoelectric encoder and proximity transducer, an ARM controller, and an executive unit of stepper motor. The system has automatic and manual variable rate fertilization modes. In the automatic mode, the system can be positioned automatically without GPS, and controls the stepping motor’s rotational speed according to the fertilizing amount in different grid to realize variable rate fertilization. In the manual mode, the controller combines the fertilizing amount in different grid input manually through the keys with the velocity of the applicator, and calculates the stepping motor’s rotational speed to realize the variable rate fertilizer application. The applicator working status can be seen in LCD on the controller. The experimental results show that the system can work properly.

Control Effect

A device for gear shifting in a gearbox with composite gears with integrated couplings in which rolling bodies are used is proposed. For device performance, the drive is carried out from a stepper motor with a combination of a screw pair and a wedge mechanism on its shaft, which increases the control effect on the coupling.
