Description

TECHNICAL FIELD

[0001] The utility model relates to the related technical field of garden soil loosening equipment, especially a soil loosening device for garden fertilization. BACKGROUND

[0002] In garden maintenance, soil loosening is an important basic work, which has a significant positive effect on the growth of vegetation. First, from the perspective of garden plant growth, soil loosening can improve the air permeability and water retention of the soil, which helps to promote the development of plant root system and water absorption, thereby improving the growth rate and survival rate of plants. Specifically, soil loosening can break the compact structure formed in the soil, avoid soil compaction, and increase the oxygen content in the soil, providing more oxygen and nutrients for the roots. At the same time, soil loosening can also break the crust layer on the soil surface, promote the infiltration of soil water, reduce water evaporation, and improve the soil water holding capacity. Secondly, from the perspective of preventing diseases and pests, soil loosening can effectively reduce the survival rate of pathogenic bacteria and pest eggs in the soil, by turning over the soil, exposing these disease and pest eggs to the atmosphere, causing them to die due to dryness and temperature changes, thereby reducing the threat to plant growth. In addition, soil loosening also improves the soil structure, making the root system grow more evenly, reducing the risk of root system being easily attacked by pathogenic bacteria due to growth constraints.

[0003] Now when using the soil loosening machine to operate, when the soil loosening machine works on uneven soil surface, the contact angle and pressure distribution of the soil loosening blade with the soil are uneven. In the convex part, the blade may be subjected to a larger impact force, while in the concave part, the blade may cut into the soil too much. This uneven stress makes the wear rate of some parts of the blade much faster than normal. For example, on uneven ground with stones or hard lumps, the blade edge may appear local chipping or rapid dulling, reducing the service life of the blade, and the uneven soil surface will cause inconsistent stress on the blade, which may cause distortion or bending deformation. Especially for thinner or slightly weaker blades, when encountering sudden changes in soil surface, the blade is prone to deformation due to excessive stress. Once the blade is deformed, its soil loosening effect will be greatly reduced, and it may also affect the normal operation of the soil loosening machine, such as causing the machine to vibrate more severely, power transmission to be not smooth, etc.

[0004] At present, there is no effective solution to the problem of uneven soil surface affecting soil loosening operation and causing blade damage in the related technology. UTILITY MODEL CONTENTS
