Design of a Small Pure Electric Tracked Tillage Machine

Abstract

To address the challenges of complex terrain, fragmented plots, varying slopes, and low levels of agricultural mechanization in hilly and mountainous areas of my country, a small, all-electric tracked tillage machine suitable for unmanned aerial vehicle (UAV) lifting and transportation was designed. Based on the characteristics of the hilly and mountainous operating environment, design requirements for the machine in terms of slope stability, passability, lightweight design, and intelligent operation were proposed. Through comparative analysis of the walking system and rotary tillage system structures, a triangular tracked walking device was selected to improve the machine's adhesion and adaptability to complex terrain. The selection and calculation of track parameters, drive motor, and reducer were completed, and the power of the rotary tillage motor and battery capacity were rationally matched. Based on this, the finite element method was used to model and simulate the vehicle frame structure. The model was reasonably simplified and shell element meshing was adopted to improve computational efficiency and accuracy. The results show that the tillage machine, while meeting lightweight requirements, possesses good slope stability and obstacle-crossing ability, effectively adapting to the complex operating environment of hilly and mountainous areas. This research provides a reference for the electrification and intelligent development of agricultural machinery equipment in hilly and mountainous areas.
