Design of the Control System of the Orchard Ditching-fertilizing Machine

In view of the actual demand of the orchard trench fertilization operation, a control system of ditching-fertilizing machine based on single-chip microcomputer is designed, and the detection and control methods of ditching depth and fertilizer amount in ditching fertilization operations are mainly studied. The system uses the STM32 F103 VET6 microprocessor as the core, uses various sensors to collect vehicle operating parameters, and realizes real-time adjustment of ditching depth and fertilizer amount by controlling the opening of the ditching cutter head lifting cylinder and the opening of the fertilizer door. Field test results show that the stability coefficient of trenching depth is lower than 90%, the average error of fertilization control is 4.02%, the control system of the whole machine has stable performance, adapts to complex environments, has high control accuracy, and meets design requirements.
