Abstract:

A wheel line irrigation system provided with a plurality of rotary, impact-type, high volume sprinklers, each of the sprinklers provided with a nozzle having a large discharge port of 0. 5 inches in diameter or greater. The pipeline is axially affixed to laterally spaced wheels; the pipeline including a main line, having a substantially horizontal longitudinal axis, and a plurality of dropped line portions, of modified V-shape, to which each respective sprinkler is attached. The inlet port of each nozzle is located at or below the longitudinal axis of the main line and preferably in a vertical plane with the main line to overcome the reactive thrust of the sprinkler and to reduce the oscillation, caused by the impact arm, of each sprinkler. Each of the dropped pipeline sections may be provided with a downwardly depending pedestal, with foot for engaging the ground, once the pipeline is filled with irrigation water, to support the pipeline and to dissipate the energy of the impact arm to ground to prevent oscillation of the pipeline.
