[0002] The main function of tillage equipment is to deep plow and loosen the land using tools such as plows, threshers, and harrows. The process is complicated and inefficient, and it can only work when the land is moist and soft. The tillage equipment is equipped with soil-breaking tools.

[0003] After searching, the patent number is CN214070539U, and the name is a utility model of a deep tillage crushing scarifier blade, which includes a blade fixing part and a blade. Through research and analysis, it is found that although the resistance of the blade to the front soil is reduced as the cutter rotates, there are still the following disadvantages to a certain extent;

[0004] For example, the structure of the soil breaker blade is single and its application range is small. It is only suitable for the soil structure in a single environment. When the soil is compacted, a deep tillage knife is used to loosen the soil, and then a dry land knife is used to break the soil to meet the planting requirements of crops. It does not have the dual tillage functions of a deep tillage knife and a dry land knife. In order to solve the above technical problems, it is necessary for us to design a deep tillage and soil breaker blade to solve the above problems. Utility Model Content
