The deep soil loosening refers to a cultivation technology for loosening soil by using external force, breaking a plough bottom layer, improving a cultivation layer structure and enhancing the water storage and soil moisture conservation and drought resistance and drainage capacity of the soil. The development of deep scarification is beneficial to the growth of crops, and is one of the important means for improving the yield of crops. In agricultural production, soil subsoiling operation mainly adopts traditional subsoiler operation, such as shovel subsoilers, vibration subsoilers and the like. In recent years, a deep scarification mode of spraying compressed gas to explode soil is developed, and the compressed gas is pressed in by an air gun and sprayed out by high-pressure gas to be used in a matched mode. The two common subsoiling modes have the following problems:
1. the traditional subsoiling mode utilizes a tractor to pull the subsoiling machine, so that the subsoiling machine is heavy in machine body, single in technology, small in application range and large in energy consumption.
2. The emerging air explosion deep scarification mode presses the air gun into the soil by means of external force such as a hydraulic cylinder or a pneumatic cylinder, then high-pressure gas is sprayed, and the surrounding soil is shattered, so that the deep scarification effect is achieved. The operation depth is relatively increased in the mode, and the method has the characteristics of wide operation range, deep scarification, uniformity and the like.
