Abstract: An improved irrigation device is provided for precision, relatively low energy and close range delivery of irrigation water to crops and the like with little or no soil erosion. The irrigation device comprises a generally cylindrical body for connection to the lower end of a vertical drop tube adapted for connection in turn to a water supply pipe, for example, of a traveling irrigation system, such as a center pivot or linear system. The cylindrical body carries a downwardly open nozzle for discharge of water into a pressure-regulated chamber defined in part by a funnel-shaped regulator cover slidable about the cylindrical body. The chamber is shaped or otherwise includes means for dissipating a substantial portion of the flow energy of the water discharged into the chamber.

Abstract: An improved irrigation boom assembly is provided for relatively rapid and easy mounting onto the main water distribution pipe of a traveling irrigation system, particularly such as a center pivot or linear travel system. The improved boom assembly includes a water supply drop pipe adapted for rapid and secure mounting onto the main distribution pipe by an improved clamp assembly and for receiving water from the distribution pipe via a flexible feed hose. The drop pipe has a manifold at its lower end designed for facilitated connection to a lightweight boom comprising a pair of elongated wing tubes cantilevered outwardly therefrom in opposite directions, wherein the wing tubes are each supported in an adjustably selected geometry by a respective pair of support cables anchored between the drop pipe and the wing tube and threaded through support struts mounted at spaced intervals along the wing tube spans. The outboard end of each wing tube includes an easily removable end fitting to permit periodic flushing.
