Design and experiment of the 3ZFC-7 omni-bearing duplex type cultivator

For development of auxiliary facilities of large tractors for field working, an omni-bearing duplex type cultivator was designed with functions of deep digging, side-fertilizing, intelligent measuring, inter-row and shoot apex weeding in meantime. The structure of parallel four-bar profiling mechanism, the spiral comb-type weeder and the vibrating fertilizer equipment were completed for better cultivating effects with the virtual prototype technology and field experiment. Structure parameters of the cultivator were optimized by several times of simulation. The field experiment and measurement showed that the machine has simple structure, good adaptability and its performance can perfectly meet agriculture technique requirements. It can satisfy the farm requirements and provide theoretical basis for later all-dimensional cultivator design.
