Pesticide spraying device

Abstract

The invention provides a pesticide spraying device, and belongs to the technical field of agriculture. The pesticide spraying device comprises a pesticide tank assembly, a supporting assembly and a plurality of spraying assemblies, the pesticide tank assembly comprises a pesticide tank and a vehicle body, the supporting assembly comprises a vertical pipe and a transverse pipe, the multiple spraying assemblies are arranged at intervals in the axial direction of the transverse pipe, each spraying assembly comprises a connecting pipe, a sleeve, a spring and a sprayer, and the first end of each connecting pipe is perpendicularly communicated with the transverse pipe; a strip-shaped hole extending in the axial direction of each connecting pipe is formed in the outer wall of each connecting pipe, the connecting pipes are sleeved with the sleeves in a sliding manner, the connecting pipes are sleeved with the springs, the springs are clamped between the transverse pipe and the sleeves, each sprayer comprises a spray pipe and a spray nozzle, the connecting pipes are coaxially sleeved with the spray pipes, and the first ends of the spray pipes abut against the sleeves; and the second ends ofthe spray pipes are in threaded fit with the connecting pipes, and the spray nozzles communicate with the strip-shaped holes. The pesticide spraying device provided by the invention can improve the pesticide spraying efficiency.

Description

technical field [0001] The invention belongs to the technical field of agriculture, in particular to a pesticide spraying device. Background technique [0002] In order to ensure the normal growth of crops and prevent breeding of diseases and insect pests, crops need to be sprayed regularly during the growth process. [0003] In the related art, the pesticide spraying device includes a medicine tank, a spray pipe, a spray head and a pull rod, one end of the spray pipe communicates with the medicine tank, and the other end of the spray pipe communicates with the spray head. The pressure is generated under the condition of manually driving the handle rod, and the pesticide can be pressed out from the medicine tank by controlling the position of the spray pipe, so as to realize the spraying of the pesticide on the crops. [0004] However, the above method needs to continuously change the position of the spray pipe to ensure uniform spraying, and the diameter of the spray pipe ...

AI Technical Summary

Problems solved by technology

[0004] However, the above method needs to continuously change the position of the spray pipe to ensure uniform spraying, and the diameter of the spray pipe is small, and it is not easy to install a flow regulating valve, which makes it difficult to control the amount of spraying (some crops need to be sprayed repeatedly), which will lead to the spraying of pesticides less efficient
