Description

Technical Field

[0001] The utility model relates to the technical field of agricultural implements, in particular to a soil loosening device for vegetable cultivation. Background Technique

[0002] Vegetables refer to a class of plants or fungi that can be used for cooking and made into food. Vegetables are one of the essential foods in people's daily diet. Vegetables can provide various vitamins and minerals necessary for the human body. According to the statistics of the International Food and Agriculture Organization in 1990, 90% of the essential vitamin C and 60% of vitamin A in the human body come from vegetables. In addition, there are various phytochemical substances in vegetables, which are recognized as components effective for health. Currently, the nutrients in fruits and vegetables can effectively prevent a variety of substances in chronic and degenerative diseases, and are being studied and discovered by people. Moreover, the soil after soil loosening is more conducive to the growth of vegetables.

[0003] When cultivating vegetables, soil loosening operations are required to facilitate the better development of seeds and the better growth and water storage of roots. However, currently, most people use a hoe held by hand for soil loosening operations. Long-term operation will cause arm strain, thus reducing work efficiency. Therefore, soil loosening equipment is needed to loosen the soil. At the same time, due to the different types and hardening degrees of the soil, different soils require different soil loosening depths. Also, during the soil loosening process, if the blade touches a hard stone, the blade will be damaged. The blades inside the existing soil loosening equipment are of an integral structure and are not convenient to replace. At the same time, when different vegetables are planted, different soil loosening depths are required, but the existing soil loosening devices are not convenient to adjust the soil loosening depth. The existing soil loosening devices have poor compatibility and limited application ranges. Content of the Utility Model
