METHOD AND APPARATUS FOR SPRAYING GROUND SURFACES

摘要

Various methods and apparatuses may be used to spray sloped surfaces, such as by using a nozzle (1). The method of the invention for spraying a fluid on turf having sloped surfaces may include spraying the fluid using a flat fan spray angle between 110 and 130 degrees and an inclination angle between 4.5 and 9.0 degrees. In some implementations, spraying the fluid may include spraying the fluid using a flat fan spray angle of approximately 120 or 127 degrees. In some implementations, spraying the fluid may include spraying the fluid using an inclination angle of approximately 4.5 degrees. In some implementations, spraying the fluid may include spraying the fluid using an inclination angle of approximately 6.5 degrees. In some implementations, spraying the fluid may include spraying the fluid using an inclination angle of approximately 9.0 degrees. In some implementations, the inclination angle may include a backward facing angle. In some implementations, the orifice of the nozzle (1) is formed by the interaction of a bent “vee” slot cut (10) though a hemispherically terminated hole creating a truncated elliptical orifice hole.

主权项

1. A nozzle for spraying plants such as turf with a fluid comprising:
(a) an outer member having a flange, a central section, a cylindrical extension terminating in a tip, a lumen extending therethrough, and a plurality of air eduction openings, said tip including an outer surface and a discharge orifice that is defined by a slot having an axis, an apex, and first and second sides, and wherein each of said sides is defined by first and second corresponding wall members, wherein: (i) said first wall members of said first and second sides extend from said apex toward their respective sides at an acute angle relative to one another in a “vee” configuration to respective opposed edges spaced from the apex, and (ii) each of said respective second wall members extend from the edge of a corresponding respective first wall member at an obtuse angle relative to one another toward an outer surface of the tip; (b) an inner member insertable into the lumen of the outer member, said inner member having a flange, a central ring, an extension, a lumen and at least one opening which cooperates with said plurality of air eduction openings in the outer member to educt air into the lumen of the inner member when liquid passed through the lumen of the inner member, into the extension of the outer member and out the discharge orifice of the tip of the outer member.
