[0002] A deep tiller is an agricultural machine that is mainly used for tilling the soil, especially for loosening, turning and breaking the tillage layer of deep soil to improve the air permeability and water permeability of the soil and promote the growth of plant roots. It is widely used in agricultural production fields such as farmland, orchards, and tea gardens, especially in areas with hardened and heavy soil, and can effectively improve the soil structure. The research on deep tillers in colleges and universities has broad academic value and application prospects, which not only promotes the progress of agricultural mechanization, but also makes positive contributions to the realization of green development and intelligent transformation of agriculture.
