[0002] Agricultural soil is also called cultivated soil. It is formed on the basis of natural soil through human production activities such as tillage, fertilization, irrigation, improvement, etc. and the combined effects of natural factors, such as the soil in cultivated land, orchards, and tea gardens. Deep tillage means that before a field is to be sown or transplanted, the field must be plowed first, the deep soil in the field must be turned up, and the shallow soil must be covered. Deep tillage is the most basic and important tillage measure in soil cultivation. It not only has the greatest impact on soil properties among the tillage measures, but also has a wide range of effects and lasts much longer than other measures. Other tillage measures such as harrowing and weeding are all carried out on the basis of this measure. When deep tillage and loosening the soil, relevant loosening devices are needed, but it still has the following disadvantages in actual use:

[0003] At present, the existing deep tillage and loosening devices for farmland soil, when in use, usually have a fixed structure of the loosening blades, and cannot add or reduce blades according to actual needs; and when the blades are damaged, they can only be replaced as a whole, and cannot be replaced individually, thereby increasing the cost of use; or the existing deep tillage and loosening devices for farmland soil, have a relatively fixed blade structure, and cannot flexibly adjust their lengths, resulting in often only being able to perform deep tillage, and not shallow tillage, and thus cultivating the fields at different depths. Therefore, it is necessary to improve a deep tillage and loosening device for farmland soil to solve the above problems. Utility Model Content
