[0002] In the mechanized ploughing and soil preparation operation process, different agricultural implements need to be operated multiple times to complete the entire agronomic requirements of sowing on ploughing and soil preparation. Frequent ploughing activities can destroy the structure of soil, break soil aggregates and soil pore structure. Soil is more susceptible to erosion by water, wind and gravity, resulting in soil loss and erosion, reducing soil fertility and productivity. In order to reduce the essential damage of excessive ploughing to soil, a shunt type land leveler is developed and researched, which can adjust the plowing depth according to the soil type, soil moisture content and soil hardness, so that the flatness of the land after plowing meets the requirements, solves the problems of unadjustable plowing depth, easy soil accumulation, poor unloading effect, uneven land and unmet sowing requirements, and in the process of leveling, only the frame is used for impact crushing, the crushing effect is poor, resulting in poor land leveling effect.
