ABSTRACT:
The disclosure is directed to a center pivot irrigation system capable of operation under high or low water pressure and a constant volume sprinkler head therefor, which together provide uniform water distribution over an agricultural field notwithstanding the presence of hills and valleys in the field, pressure fluctuations of the water source, friction losses or the direction or magnitude of the wind. The system employs a plurality of sprinkler heads each of which provides a constant volume of water to the annular area over which it travels. Because the annular areas increase in size and total water requirements with increasing distance from the center pivot, the water delivering capacity of each sprinkler head is chosen as a direct function of its radial distance from the center pivot, thus insuring the same water distribution to all points on the field. Each sprinkler head is designed to produce a spray pattern that extends laterally outward with a predetermined directional orientation. A vertical tail or rudder associated with the sprinkler head acts in weather vane fashion to direct the directional spray pattern into the wind at all times, thus preventing the water spray from being blown from its intended area, which results in nonuniform distribution. The sprinkler heads are also constructed for tipping relative to a vertical axis, and ailerons extending laterally from the rudder act to tip the head and spray pattern downward to a degree in the face of particularly strong winds, thus insuring that the water reaches its destination.
