Description

Pesticide sprinkler

Technical Field

The invention belongs to the technical field of agriculture, and particularly relates to a pesticide spraying device.

Background

In order to ensure the normal growth of crops and prevent the breeding of plant diseases and insect pests, the crops need to be regularly sprayed in the growth process.

In the correlation technique, the pesticide spraying device comprises a pesticide tank, a spray pipe, a spray head and a hand lever, wherein one end of the spray pipe is communicated with the pesticide tank, and the other end of the spray pipe is communicated with the spray head. Pressure is generated under the condition of manually driving the hand lever, and the pesticide can be pressed out of the pesticide tank by controlling the position of the spray pipe, so that the pesticide is sprayed on crops.

However, the above method requires the position of the nozzle to be changed continuously to ensure uniform spraying, and the nozzle has a small diameter, so that it is difficult to install a flow control valve, which makes the spraying amount difficult to control (part of the crops need to be sprayed repeatedly), which results in inefficient spraying of the pesticide.

When the pesticide spraying device provided by the invention sprays the pesticide on crops, firstly, the transverse pipe 22 is adjusted to a proper length, so that the spraying range of the pesticide is ensured to cover the crops. Due to the spaced arrangement of the plurality of spraying assemblies 3, the vehicle body 12 can enable the spraying assemblies 3 to uniformly spray crops during movement.

Then, the position of the nozzle 341 on the connection pipe 31 is adjusted according to the amount of the sprayed pesticide, so that the sleeve 32 can be driven to move axially on the connection pipe 31.
