Method and apparatus for a spray system

摘要

An improvement to a roadside sprayer fixates spray nozzles on a registration plate. The registration plate may include integral tabs depending on the application. Inclination of the tabs is adjustable to place streams and droplets in a desired swath coverage. With the nozzles rigidly mounted onto the plate, the entire plate is nutated. The use of the registration plate in a spray unit creates a uniform nutation among the nozzles, thereby reducing variability in droplet placement, and providing a more predictable spray from the nozzles. In other embodiments, the spray unit is utilized in a spray system adaptable to service vehicles, and may be utilized in conjunction with a vegetation engagement device, such as a cutter to engage multiple zones of a roadway right-of-way. Additionally, an improved spray unit includes an electromagnetic field and an attractor to generate plate motion.

主权项

1. A spray system, comprising:
a spray head support; an electromagnet disposed on the spray head support that generates an electromagnetic field; a spray unit, comprising a spray arm; and
the spray arm, comprising:
a plate portion including a first end coupled with the spray head support and a second unsupported end, the plate portion comprising a corrosion resistant metal non-reactive to the electromagnetic field generated by the electromagnet,at least one aperture disposed within the plate portion,at least one nozzle disposed in the at least one aperture of the plate portion, whereby a fluid is delivered through the at least one nozzle, andan attractor rigidly secured to the second unsupported end of the plate portion, the attractor comprising a discrete metal block reactive to the electromagnetic field generated by the electromagnet, wherein the electromagnet moves the attractor, thereby forcing movement of the plate portion.
