13%～18%。Soil deep loosening operation can break the hard-pan without flipping the soil. It can effectively improve the water and air permeability performance of the soil, and provide a broader space to the plant roots. To solve the existing problems, such as insufficient loosening depth, big tillage resistance and the power consumption for general types of deep loosening machines, a new type of the lever vibrating ripper is developed. The ripper is consist of five main parts, the stander, eccentric axis, crisscross connector, deep loosening shovels and wheels for depth control. The crisscross connector makes this machine achieve double vibrations. The power is transmitted effectively and tersely by the gimbal and the lever, which can enlarge the vibration displacement and increase amplitude with the increasing deep tillage. The form of shovels is narrow chisel-type so that it can maximize the protection of the soil and reduce the moisture evaporation. Contrastive experiment of vibrating and non-vibrating subsoiling operation is carried out to analyze the impact of vibration on the traction resistance. The experimental results indicate that the operation traction resistance can be reduced 13%～18%.
