Variable amount spraying device capable of automatically mixing pesticide

Abstract

The invention relates to a variable amount spraying device capable of automatically mixing pesticide. The variable amount spraying device capable of automatically mixing the pesticide can adjust the amount of the automatically-sucked pesticide according to the requirements of spraying to change the concentration of spray, and can achieve the purpose that the pesticide and water are separately stored. The variable amount spraying device capable of automatically mixing the pesticide comprises a water tank for storing the water, a pesticide tank for storing liquid pesticide, a solenoid valve playing a role in protection, a mode backflow check valve, a jet flow pesticide mixing device, a pressure gauge, a plunger pump for providing power needed by spraying, a flow meter, pipelines and spraying nozzles. The pesticide and the water are independently stored, the variable amount spraying device capable of automatically mixing the pesticide can automatically and stably carry out pesticide suction in the process of spraying, on-line uniform mixing can be carried out, and real-time control over the amount of the sprayed pesticide can be carried out. In order to meet the requirement for developing high-efficiency agriculture, the variable amount spraying device capable of automatically mixing the pesticide can be mounted on a vehicle, and can be hung on an ordinary agricultural machine, and power of the variable amount spraying device capable of automatically mixing the pesticide can be provided by the ordinary agricultural machine, and large-area high-efficiency spraying operation can be achieved.

Description

technical field [0001] The invention relates to a variable-variable spraying device for automatic drug mixing, which automatically absorbs the drug and stores water and the drug separately, and can realize variable-concentration spraying, which belongs to the field of plant protection spraying. Background technique [0002] At present, the proportion of mechanized production in agricultural production is also increasing, and it is developing towards efficient agricultural production. my country's plant protection machinery has achieved rapid development in recent years. Due to the transfer of production labor, agricultural production has a tendency to develop from small farmers to collective farms. Therefore, it is necessary for plant protection machinery to develop in the direction of large-scale and high-efficiency. Therefore, the characteristics of high efficiency, speed and high automation of plant protection machinery have become a research hotspot of plant protectio...

AI Technical Summary

Problems solved by technology

What follows is the problem of mixing the liquid medicine and water in the spraying operation. The pre-mixed type is labor-intensive and unevenly mixed. Manual mixing is very easy to contact pesticides, which will cause harm to personal safety and easily cause The waste of pre-mixed pesticide liquid also causes a series of adverse factors such as pollution to the environment

The premixed type cannot effectively control the concentration of the chemical solution in time, and the premixed type is generally destructive to the corrosion of the active liquid pump and increases the production cost.

At present, there are some devices that realize online drug mixing. The application date is May 6, 2008, and the Chinese patent "Variable Spray Automatic Mixing Device" with application number 200810027898 discloses a drug mixing device. The main consideration of this device is that the spray concentration can be changed in real time. , one or more medicines are sprayed alone or at the same time, there is still a harmful effect of the medicine liquid on the liquid pump
