Abstract
Equipment for spraying a fluid such as a herbicide comprises a support tube on which is mounted a head comprising a body and a rotatable disc. Electrical supply leads and a supply hose for fluid pass to the head through the support tube. The head and the body define between them a narrow annular gap. Fluid is supplied to the disc at a position radially inwards of the gap and flows through the gap to be discharged as fine droplets from the periphery of the disc. The width of the gap is such that the fluid passing through it is wiped circumferentially so that it is distributed around the disc. This promotes an even spray of fluid from all parts of the periphery of the disc. Special shapes for the disc are proposed in order to promote the formation of small droplets of uniform size.
Claims16
Spraying equipment comprising a hollow support tube fitted at one end to a handset, the other end of the tube carrying a spraying head comprising an atomizing disc and an electric motor for driving the atomizing disc in rotation, the equipment further comprising an electrical lead connected to the motor, and a liquid supply tube for supplying liquid to the atomizing disc, the electrical lead and the supply tube extending within the tube and the electrical lead being provided with means for connection to a source of electrical power, the handset comprising a handle member provided with a valve for controlling the flow of fluid through the supply tube, the outlet of the valve being connected in a fluid-tight manner to the supply tube and the inlet of the valve being connected in a fluid-tight manner to an intermediate duct which extends through the handle member and is provided with means for connecting the intermediate duct to a container of liquid to be sprayed.
