[0002] A rotary tiller is a tilling machine that is used with a tractor to complete ploughing and harrowing operations. It is widely used because of its strong soil crushing ability and flat surface after ploughing. It can also cut up the root stubble buried below the surface, which is convenient for the seed drill to operate and provide a good seed bed for later sowing. According to the configuration of the rotary tiller shaft, it is divided into three types: horizontal shaft type, vertical shaft type and inclined shaft type. Correct use and adjustment of the rotary tiller is very important to maintain its good technical condition and ensure the quality of tillage.
[0003] The shortcomings of the existing technology: However, when the rotary tiller is running, although the rhizomes in the soil can be taken out, the taken out rhizomes are difficult to crush, difficult for the soil to absorb, and will also affect the normal cultivation of the land.
