Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to an adjustable three-tooth hook for plowing. Background Art

[0002] In agricultural production, the structure, air permeability, water retention and fertilizer retention of soil are crucial to plant growth. Good soil structure can improve the air permeability and water permeability of the soil, which is conducive to the growth and development of plant roots. In addition, the fertilizer retention of the soil also directly affects the nutrient supply of plants, thereby affecting the yield and quality of crops. Therefore, how to improve the structure of the soil and improve its air permeability, water retention and fertilizer retention is an important topic in agricultural production.

[0003] Among the existing agricultural machinery and equipment, plowing equipment is a commonly used farm tool, which is mainly used to turn over the soil and loosen the soil to improve the soil structure and increase the air permeability and water retention of the soil. However, traditional plowing equipment is usually single-toothed. Although this design is simple, the turning over effect is poor and large clods of soil cannot be broken. At the same time, the existing plowing equipment often leaves narrow and unclear furrows during the turning over process, which not only affects the structure of the soil, but may also affect the subsequent sowing and fertilization work. Finally, the existing plowing equipment may scatter the fertilizer in the soil during the turning over process, affecting the soil's fertilizer retention, which is also a problem that the existing equipment needs to solve.
