Abstract:
1. A liquid spray system for spraying vegetation comprising: an elongated liquid supply boom movable for travel in a direction of movement perpendicular to its elongated length, a liquid spray nozzle having a nozzle body with a liquid inlet in fluid communication with said liquid supply boom and a liquid flow passage extending along an axis of said nozzle body, said nozzle body having a first liquid discharge orifice communicating with said liquid flow passage for discharging pressurized liquid from said liquid flow passage and a first deflector flange having a lip portion that projects downwardly and forwardly in relation to said direction of movement at a first angle to the nozzle body axis for directing a first pressurized liquid spray discharging from said first discharge orifice at said first angle to said nozzle body axis in a leading direction relative to movement of said boom, and said nozzle body having a second discharge orifice communicating with said liquid flow passage for discharging a second pressurized liquid spray from said liquid flow passage simultaneously with and separate from said first liquid spray and a second deflector flange surface that projects downwardly and rearwardly in relation to said direction of movement at a second angle to the nozzle body axis different from said first angle, the angle the first deflector flange projects forwardly with respect to the nozzle body axis for directing the second discharging liquid spray from said second discharge orifice in a trailing direction relative to said movement of said boom and at said second angle to said nozzle body axis such that said spray nozzle simultaneously sprays liquid on front and back sides of vegetation during a single passage of said spray boom in the direction of movement.
