Description

Technical Field

[0001] The invention relates to the technical field of agricultural tools, in particular to a large-scale planting rotary tillage and fertilization machine. Background Art

[0002] The rotary tillage fertilizer is a tillage machine that is used in conjunction with a tractor to complete plowing and harrowing operations. It has been widely used because of its strong soil crushing ability and flat surface after plowing. It can also cut up the root stubble buried below the surface, which is convenient for the operation of the seeder and provides a good seed bed for later sowing. The rotary tillage fertilizer has the functions of breaking the plow bottom layer, restoring the soil tillage layer structure, improving the soil's water storage and moisture retention capacity, eliminating some weeds, reducing pests and diseases, leveling the surface, and improving the standards of agricultural mechanization operations. It can also carry out fertilization operations, which can improve the soil fertility and provide sufficient nutrients for crop growth.

[0003] First, the presence of gravel inside the soil can improve the soil structure. Gravel can make the soil looser and reduce soil compaction, which is beneficial to the growth and development of plant roots. Secondly, the gaps between the gravel can increase the air permeability of the soil, making the air circulation in the soil smoother and beneficial to the respiration of plant roots. Finally, gravel can enhance the drainage performance of the soil and prevent excessive water from causing plant root rot. In the rainy season or when watering too much, gravel can quickly drain excess water and keep the soil moderately moist.

[0004] At present, when the existing rotary tillage fertilizer applicator is performing rotary tillage operation, stones will inevitably appear inside and on the surface of the land. When the stones come into contact with the rotary tillage blades, the rotary tillage blades will be broken, and in serious cases, the rotary tillage blades will even be broken. The rotary tillage seeder cannot sort the stones on the land that needs to be rotary tilled and use them after processing, which affects the service life of the rotary tillage blades and causes inconvenience in use.
