ABSTRACT:
An electrostatic nozzle assembly for coating row crops and other plants with electrostatically charged particles of pesticide including a nozzle body formed with passageways to receive air and a grounded stream of waterborne pesticide for delivery through a nozzle tip to an inductor ring mounted between the nozzle body and an air nozzle having a discharge orifice. As the stream of waterborne pesticide is projected from the nozzle tip, it is impacted with a swirling, spirally moving stream of air produced by a swirl plate having a plurality of tapered air channels oriented tangentially relative to the pesticide stream and communicating with the air passageway in the nozzle body. The inductor ring inductively charges the pesticide in the terminal end of the nozzle tip. The swirling air stream atomizes the charged pesticide stream expelled from the nozzle tip into finely divided particles, and then imparts the swirling motion to the charged particles which fan radially outwardly in a wide spray pattern when ejected from the discharge orifice in the air nozzle. An electrical standoff is also provided by forming the air nozzle with an irregularly-shaped outer surface which lengthens the electrical path which charged particles collected on the air nozzle would have to travel to migrate to the grounded support for the nozzle body or the nearest grounded point.
