Height-adjustable automatic water-feeding mixing and spraying device of pesticide

Abstract

The invention discloses a height-adjustable automatic water-feeding mixing and spraying device of pesticide. The device comprises a base, and the top of the base is fixedly provided with a pesticide box; the right wall of the pesticide box is also fixedly connected with a pressurization cylinder through a bracket, a water inlet pipe is connected to the left side of the bottom of the pressurizationcylinder, penetrates through the side wall of the pesticide box and is connected to the lower right corner of the interior of the pesticide box, a second three-way valve is arranged on the water inlet pipe, a right end port of the second three-way valve is connected with a water feeding pipe, and the right end of the water feeding pipe is connected with a water feeding hose; a circulating pipe isconnected to the right side of the bottom of the pressurization cylinder, penetrates through the side wall of the pesticide box and is connected to the top of the interior of the pesticide box, a water outlet end of the pesticide box is also fixedly connected with a first spraying nozzle, the circulation pipe is provided with a first three-way valve, and a right end port of the first three-way valve is connected with a water outlet pipe. According to the device, the three different functions of water feeding, pesticide cycle mixing and automatic pesticide spraying can be controlled and achieved by adjusting the communicating directions of the first three-way valve and the second three-way valve, the device is easy to operate and convenient to use, the work efficiency is greatly improved,and the manual labor amount is reduced.

Description

technical field [0001] 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 [0002] 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. [0003] 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 ...

Problems solved by technology

[0003] 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. , some taller plants cannot be sprayed with pesticides, and ordinary pesticide spraying vehicles have the problems of uneven mixing of pesticides and easy deposition during spraying, which will affect the spraying effect of pesticides and are not conducive to plant growth
