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 first frame adaptable to a service vehicle; a second frame connected to the first frame; a spray head frame connected with the second frame; a motion inducer mounted to the spray head frame; a registration plate coupled with the motion inducer, the registration plate comprising at least a first tab with an aperture therein and a second tab with an aperture therein; a first nozzle secured in the aperture of the first tab and a second nozzle secured in the aperture of the second tab, whereby the first and second tabs provide a rigid mount for the coupling of the first and second nozzles with the registration plate; a first flow control unit mounted on the second frame, the first flow control unit fluidly coupled to a fluid source and to the first and second nozzles to deliver a fluid from the fluid source to the first and second nozzles when the first flow control unit is in an on position and cease the delivery of the fluid when the first flow control unit is in an off position; and the motion inducer induces a motion to the registration plate during the delivery of fluid to the first and second nozzles by the first flow control unit to create droplet separation as the fluid exits the first and second nozzles, wherein the first flow control unit is isolated from the motion produced by the motion inducer due to its mounting on the second frame.
