In order to improve the effect of subsoiling,a new type pneumatic subsoiler based on pneumatic fracturing theory was designed.The subsoiling is achieved by injecting high pressure air into soil without turning.The entire structure,working principle and control system of pneumatic subsoiler was designed,and then,calculation and motion of key components were designed and analyzed.After that,the motion trajectories of injection port were simulated.The results show that injection port moves along the predetermined trajectory with the designed parameters.When the horizontal distance is 1.4 m,the optimal subsoiling performance can be obtained by the coordination of different injection depth.
