This machine is a new type of compound soil preparation equipment that integrates soil deep loosening and tillage. It can be used in combination with deep loosening and rotary tillage, and can also be used as an independent unit separately with tractors, with strong practicality. It breaks the traditional agronomy of only deep loosening without tillage, meeting the needs of deep loosening for arid and saline alkali land on the one hand, and soil tillage before crop sowing on the other hand. The machine is composed of a front deep loosening machine and a rear rotary tiller. The deep loosening component is a chiseled double wing shovel, and both the shovel tip and the double wing shovel are made of high-quality 65Mn steel, with high wear resistance and good toughness. This machine is suitable for cultivation in arid, semi-arid, and hilly areas. It can be combined with fertilization for soils with poor tillage layers that are not suitable for deep plowing, such as saline alkali soil, white soil, loess, etc. Deep loosening has become the main measure for improving soil quality, and it also has a significant effect on water storage and moisture retention. Deep loosening in the front and tillage in the back, the surface is leveled and the soil is fluffy after one operation, meeting the requirements for sowing and reducing farmers' cultivation costs.
