SIMULATION ANALYSIS AND EXPERIMENTAL STUDY OF THE HYDRAULIC SYSTEM FOR AN AUTOMATIC LEVELING PADDY FIELD LAND PREPARATION MACHINE USING AMESim

Paddy field tillage and soil preparation form the foundation of rice production. To address the low operational efficiency and insufficient leveling accuracy of traditional paddy field preparation equipment, this study developed an automatic leveling control system for paddy field land preparation machinery. The system integrates hydraulic technology with sensors and a microcontroller, using an M 4/3 solenoid directional control valve to achieve automatic leveling. Simulation results obtained using AMESim software indicate that the hydraulic cylinder piston can fully extend within 11 s, demonstrating suitability for the automatic leveling process. Prototype testing further verified that the system operates with stability, safety, and reliability. The implementation of this control system contributes to improving the degree of automation in tillage and land preparation machinery during rice cultivation and supports the advancement of intelligent and information-based agricultural equipment.
