Compressed sprayer

Abstract

A compression sprayer comprises a pesticide tank which is provided with a manual pneumatic pump. A handle is arranged on the manual pneumatic pump and a suction pipe is arranged in the pesticide tank. The suction tube is connected with a leather hose and the leather hose is connected with a spray boom. The spray boom is connected with a sprinkler. The invention is characterized in that an angle adjustment part is arranged between the sprinkler and the spray boom; a notch is cut in a base of the pesticide tank; a foot board is arranged in a notch; and the notch is fixed by the foot board and nuts. The technical schemes of the invention are that the angle adjustment part is arranged between the sprinkler and the spray boom, which can freely adjust the angle of the sprinkler while spraying a pesticide, thus being able to spray directly forwards, or spray to the left or the right sides, and spray the pesticide to the leaf surface, the stem and the root, etc., of the crops according to different requirements and has a good spray effect. In addition, the foot board is arranged on the base of the pesticide tank that can be turned to the bottom surface of the tank while being out of service, and be turned out while pumping, so that while pumping with hands, the foot board can be trampled to prevent the tank from moving. The invention uses two hands to pump, thus being convenient and saving labor.

Description

technical field [0001] The invention relates to a sprayer, in particular to a compressed sprayer, which belongs to agricultural plant protection machinery. Background technique [0002] Sprayers are a kind of commonly used agricultural plant protection machinery, which can be divided into manual sprayers and electric sprayers. Manual sprayers are mainly composed of liquid medicine barrels, manual air pumps and spray booms. However, the existing manual sprayer has the following disadvantages: one, the spraying angle of the nozzle on the spray bar cannot be adjusted, and it can only be sprayed directly or sideways, which has great limitations; It is often necessary to press the liquid medicine barrel with one hand and inflate it with the other hand, or clamp the liquid medicine barrel with both legs. It is very laborious and strenuous to operate. Sometimes it is placed on the ground or rested on the liquid medicine bucket, so it is messy and takes up a lot of volume, so it is...

However, the existing manual sprayer has the following disadvantages: one, the spraying angle of the nozzle on the spray bar cannot be adjusted, and it can only be sprayed directly or sideways, which has large limitations; It is often necessary to hold down the liquid medicine barrel with one hand, inflate it with the other hand, or clamp the liquid medicine barrel with both legs, which is very laborious and strenuous to operate. Sometimes it is placed on the ground or placed on the liquid medicine bucket, so it is messy and takes up a lot of volume, so it is inconvenient to store and move
