Xinfeng Mini Lesson—Understanding How Landscape Sprayers Work

Landscape sprayers come in suspended, towed, and self-propelled models.

The most common models are typically small to medium-sized towed types driven by a power take-off shaft. However, future developments are likely to focus on compact suspended or self-propelled designs.

The former offers lower costs, while the latter provides better maneuverability and superior hill-climbing ability, making them ideal for densely planted or sloped orchards.

The working principle of garden sprayers is as follows: When the tractor drives the liquid pump, water from the chemical cabinet enters the pump via the suction nozzle, switch, and filter.

It then flows through the return pipe and agitation pipe connected to the main switch of the pressure-regulating distribution cabinet into the chemical tank. Pesticides are added to the tank at the required ratio during water filling, allowing the sprayer to mix pesticides while adding water.

During spraying, the liquid in the chemical tank flows through the liquid pump's outlet pipe, filter, and inlet pipe into the liquid pump. Driven by the pump, the liquid enters the master switch of the pressure-regulating distribution valve via the pump's outlet pipe.

When the master switch is activated, a portion of the liquid flows through two separate valves into the spray device's spray pipes.

Pressurized liquid is atomized into mist at the nozzles. The mist droplets undergo further atomization by the powerful airflow generated by the fan, while the fine mist is blown into the canopy of fruit trees.
