The V-shaped subsoiling shovel can deeply loosen 25 to 45 cm and achieve the purpose of all-round deep loosening without destroying the soil layer structure. A mouse hole was opened, and the ground was flattened, and the whole soil was slightly vibrated, which was conducive to moisture conservation, water storage, salinity and alkali drainage, and ventilation.

3) The utility model includes a subsoiling part and a rotary tillage part, which can realize the joint operation of subsoiling and rotary tillage, and the rotary tillage operation is carried out on the subsoiled tillage belt, and the surface soil is broken and leveled, which can meet the needs of intensive cultivation. Agronomic requirements.

4) Set markers on both sides of the steel pipe main girder or on both sides of the rotary tillage frame respectively, which can ensure that the unit runs along a straight line in the field, the back and forth handover lines are correct, and the line spacing is uniform.

5) The overall design of the utility model is reasonable, the structure is simple, the cost is low, and the operation quality is good.
