Description

speed sprayer {SPEED SPRAYER}

Embodiments of the present disclosure relate to a speed sprayer, and to a speed sprayer capable of delivering a chemical solution over a wider range to a greater distance, and a speed sprayer capable of autonomous driving.

The conventional pesticide spreader installed a drug spreader, and a blower fan was installed in the drug spreader to refract the wind sucked from the front in a right angle direction and send it out in the spray nozzle direction, so the spraying range of the drug was limited in the installation direction of the nozzle.

In addition, since the spraying distance of the drug was simply determined by the driving strength of the blowing fan, the spraying distance of the drug was limited, and there was a problem that the drug did not reach the top of the tall fruit tree, so that the control power was lowered.

In order to compensate for this, a method of installing a large-capacity high-output blower fan has also been proposed, but there is a disadvantage in that the operating noise becomes excessively large and the overall size of the chemical spreader becomes excessively large.
