Description

A height-adjustable pesticide automatic water mixing spraying device

technical field

The invention relates to the technical field of agricultural machinery, in particular to a height-adjustable automatic water-adding and mixing spraying device for pesticides.

Background technique

Pesticide refers to a class of drugs used to kill insects, bacteria, and harmful animals (or weeds) in order to ensure and promote the growth of plants and crops in agricultural production. Specifically refers to pesticides used in agriculture to control diseases and insect pests, regulate plant growth, and kill weeds.

Nowadays, small-scale pesticide spraying mostly uses a backpack-type pesticide spraying box to spray pesticides. This kind of backpack-type pesticide spraying box mainly uses manpower as the driving force for pesticide spraying. Pesticide spraying wastes time and energy. The effective spraying area is small and the spraying efficiency Very low; there are also some areas that use small pesticide spraying vehicles for pesticide spraying. Generally, small pesticide spraying vehicles are manually pushed and moved, which is relatively more energy-saving, but their functions are relatively single, the spraying height cannot be adjusted, and the scope of spraying is narrow. , For some taller plants, it is impossible to spray pesticides, and ordinary pesticide spraying vehicles have problems such as uneven mixing of pesticides and easy deposition during spraying, which will affect the spraying effect of pesticides and are not conducive to plant growth.
