Water sprinkler with adjustable spread - has oscillating perforated pipe section with adjustable curvature

摘要

The sprinkler has a curved pipe section (2) with a line of perforations to spray over a set area. The pipe section oscillates about its length, driven by a motor (4) at one end. The motor is water driven. The curvature of the pipe section is adjustable by a scale adjuster (8) to set the spray spread. The angle of oscillation is adjustable by varying the stops on the drive motor. The spray area is square. ADVANTAGE - Adjustable spray area, no overspray of unwanted areas.
