Backpack pressure sprayer

Abstract

The invention discloses a backpack pressure sprayer, which comprises a chemical storage box and a spraying device arranged under the chemical storage box, wherein a spray thrower is arranged at one side of the spraying device; a stirring device is arranged at the bottom of the chemical storage box, and comprises a pneumatic telescopic rod; a baffle plate is arranged at the upper end of the pneumatic telescopic rod; the baffle plate comprises a plurality of circular arc-shaped baffle sheets; the plurality of circular arc-shaped baffle sheets form a whole circle; the end part of each circular arc-shaped baffle sheet is rotationally connected with the upper end of the pneumatic telescopic rod. The backpack pressure sprayer has the advantages that the stirring device is arranged at the bottom of the chemical storage box; the stirring device drives the plurality of rotationally connected circular arc-shaped baffle sheets to vertically move to realize stirring through the vertical movement of the pneumatic telescopic rod; compared with an ordinary stirring device, the stirring device provided by the invention has a small and exquisite structure; the stirring effect is good; the plurality of circular arc-shaped baffle sheets are rotationally connected with the end part of the pneumatic telescopic rod; the continuous flapping movement can also be realized in the vertical movement process.

Description

technical field [0001] The invention relates to the technical field of agricultural and forestry sprayers, in particular to a knapsack pressure sprayer. Background technique [0002] During the use of the agricultural and forestry sprayer, it is necessary to mix the agent with water in proportion, and then spray the agriculture and forestry, and the agent can be solid or liquid, and the liquid agent can be mixed directly, while the solid agent needs to be dissolved in proportion After mixing, whether it is a liquid drug or a solid drug, it needs to be stirred after adding the drug to facilitate the thorough mixing of the solution. [0003] Stirring in the prior art is generally divided into stirring before use and stirring during use. For convenience and trouble-saving, some medicaments are only fully artificially stirred after dosing and before spraying, so that there is no need to add a stirring device to the spray, which saves costs. , but the concentration of the soluti...
