Now more and more fruit farmers choose orchard sprayers, but there are many specifications, models and manufacturers of orchard sprayers on the market. So, how to choose an orchard sprayer?
First, we must understand the types of orchard sprayers
Including self-propelled, suspended, and towed. Among them, both the suspension type and the traction type require tractors as supporting power. The former is economical and practical, with strong mobility, while the latter has strong climbing ability and is suitable for dense planting or sloping orchards.
Secondly, we must understand the structure of the orchard sprayer. Orchard sprayer is mainly divided into two parts: power and spray. The spraying part is composed of liquid tank, fan, plunger pump or diaphragm pump, pressure regulating distribution valve, filter, suction valve, transmission shaft and spraying device, etc. There are several nozzles on each side of the nozzle, arranged in a fan shape, adjustable Spray range.
Finally, it is necessary to be clear about the working principle of the orchard sprayer. When the tractor's rear output drives the liquid pump, the water in the medicine tank enters the liquid pump through the head, switch, and filter, and then passes through the return pipe and the mixing pipe of the pressure regulating distribution switch. Enter the medicine tank. While adding water to the medicine box, add pesticides and mix them in the required proportions. When spraying, the liquid medicine in the medicine tank 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 medicine enters the main switch of the pressure regulating distribution valve from the outlet pipe of the pump, and passes The medicine tube enters the nozzle of the spray device. At this time, the pressurized liquid medicine is sprayed out in a mist under the action of the nozzle, and the strong air flow generated by the fan will atomize the mist again, and at the same time blow the atomized fine mist to the canopy of the fruit tree.
