Description

Hand-held automatic uniform fertilizer device Technical Field The invention relates to the technical field of agricultural machinery, in particular to a hand-held automatic uniform fertilizer device. Background In the current agricultural planting, gardening maintenance and greenhouse operation fields, periodic fertilization is a key link for ensuring healthy growth of crops and improving unit yield. For large-area open farmlands, large-scale mechanized fertilizer spreaders are commonly adopted at present to perform operations, and for areas with complex terrains, high planting density or limited operation space (such as hilly orchards, nursery gardens and vegetable greenhouses), light-weight auxiliary tools are more relied on. Most of the existing tools are of simple knapsack type or simple hand-push type structures, and aims to solve the problem of long-distance transportation of fertilizers, so that the fertilization process can be completed in relatively narrow rows. However, the existing small and medium-sized fertilization operation still has significant defects in practical application, and the current fertilization process is mainly carried out manually. The operation mode highly dependent on manpower has the advantages of extremely high labor intensity and low operation efficiency, and the discharge amount and the distribution range of the fertilizer are completely controlled by manual hand feeling or experience, so that the uniformity of the distribution of the fertilizer is extremely difficult to ensure. This often results in local fertilizer build-up that causes "burn-up", or partial regional nutrient starvation that affects growth, resulting in fertilizer waste and environmental pollution. Meanwhile, long-term manual repeated operation is easy to cause chronic injury to lumbar vertebrae and arms of operators. Disclosure of Invention The invention aims to provide a hand-held automatic uniform fertilization device, which solves the problem that the fertilization process is mainly carried out manually at present.
