What kinds of orchard spray machines are available
It is understood that the types of orchard sprayers on the market at present mainly include self-propelled, hanging, traction, hanging and traction. They all need tractors to power them. The former economical and practical, strong mobility, the latter climbing ability is strong, suitable for dense planting or slope orchard.
How to choose orchard spray machine scientifically
First, to understand the structure of orchard spray machine.
Orchard spray machine is mainly divided into power and spray two parts. The spray part is composed of liquid medicine tank, fan, plunger or diaphragm pump, pressure regulating distribution valve, filter, suction valve, drive shaft and spraying device, etc. Each side of the nozzle is equipped with a number of nozzles, which are arranged in a fan-shaped way, and the spray range can be adjusted.
Secondly, we should understand the working principle of orchard spray machine.
When the rear output of the tractor drives the liquid pump to operate, the water in the medicine cabinet enters the liquid pump through the water head, switch and filter, and then enters the medicine cabinet through the return pipe and stirring pipe of the main switch of pressure regulation distribution. At the same time as adding water to the medicine cabinet, add pesticides to the medicine cabinet in the required ratio, and mix pesticides at the same time as adding water. When spraying, the liquid in the medicine cabinet enters the liquid pump through the outlet pipe, filter and the inlet pipe of the liquid pump. Under the action of the pump, the liquid enters the main switch of the pressure regulating distribution valve from the outlet pipe of the pump, and enters the nozzle of the spraying device through the drug delivery pipe. This is the liquid with pressure under the action of the nozzle, sprays out in the shape of mist, and generates a strong air flow through the fan. The droplets are atomized again, and the atomized droplets are blown into the canopy of the fruit trees.
