a sprayer

Abstract

The invention relates to a pesticide sprayer, aiming at solving the problems that an existing pesticide sprayer adopts proportioned pesticide liquid and is limited by a capacity and the working efficiency is influenced. The pesticide sprayer comprises a knapsack; a pesticide spraying pump and a pesticide cabin are arranged on the knapsack; the pesticide sprayer is characterized in that concentrated pesticide liquid is loaded into the pesticide cabin; the knapsack is further connected with a water suction pipeline; a floating body is arranged at a bottom end of the water suction pipeline; a check valve which gets through upward is arranged at the center of the floating body; the check valve is connected with a water inlet end of a three-way connector through a hose; a water inlet switch is arranged at the water inlet end of the three-way connector; the three-way connector further comprises a pesticide inlet end connected with the pesticide cabin and an outlet end of outputting mixed water and concentrated pesticide liquid; the outlet end of the three-way connector is connected with the pesticide spraying pump through a pesticide feeding pipe. According to the pesticide sprayer, the knapsack carries the concentrated pesticide liquid and the concentrated pesticide liquid is diluted through pumping the water in the field; the pesticide carrying amount of the pesticide sprayer is greatly increased, the load is reduced and the cruising ability of the pesticide sprayer is improved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and relates to a sprayer, in particular to a sprayer for separating medicine and water. Background technique [0002] During the growth process, crops will be harmed by diseases, insects, weeds, rats, etc. to varying degrees. In order to prevent or reduce the loss of crops, chemical pesticides are usually used to prevent and control crop diseases, insects, weeds, and rats. Among them, the most commonly used method when using chemical pesticides is the spray method. The spraying method refers to the application method in which the pesticide is prepared into an emulsion or suspension with water, and then the liquid pesticide is sprayed into a mist dispersion system with a pump body. The spraying method usually requires the cooperation of a sprayer. The traditional single-operated sprayer is generally a backpack type. The operator puts a well-proportioned liquid medicine into the cartridge, an...
