DESIGN AND FIELD EXPERIMENT ON 1SZ-460 LEVER-TYPE SUBSOILER
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, which provides 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 was developed. The ripper is consist of five main parts, including the frame, eccentric axis, crisscross connector, deep loosening shovels and wheels for depth control. The main characteristics of the ripper are: 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 buried easily, besides, the amplitude will increase with the increasing deep tillage; the form of shovels is narrow chisel-type which can maximize the protection of the soil and reduce the moisture evaporation. Contrastive experiment of vibrating and non-vibrating subsoiling operation was carried out to analyze the impact of vibration on the traction resistance. The experimental results indicated that 13％～18％ of operation traction resistance could be reduced.
