ABSTRACT:
A land irrigation system in which a continuously traveling sprinkler line is supplied with water from a stationary water supply conduit extending in the direction of the movement of the sprinkler line, the apparatus of the invention being designed to continuously supply water to the sprinkler from spaced risers forming part of the water supply conduit. A conveyance moves along the water supply conduit, the conveyance carrying a rotating water manifold with a plurality of water carrying arms extending from the water manifold in angularly spaced relation to each other for successive connection to water outlet valves on the risers as the conveyance moves along the water supply conduit. The water outlet from the water manifold is connected to the water inlet of the sprinkler line in such a manner that the water manifold and water carrying arms can rotate relative to the inlet of the sprinkler line. The water inlet end of each water carrying arm couples with successive outlet valves of successive risers for opening and closing the riser water outlet valves and in each case the coupled water carrying arm is uncoupled from one riser when another water carrying arm has coupled with another riser and opened the water outlet valve of that riser. With one coupling member connected to one riser, power assist means and/or movement of the conveyance along the water supply conduit can be utilized to cause the water manifold and water carrying arms to rotate around the connected riser and also relative to the conveyance to bring another coupling member into contiguity with the next riser in the direction of conveyance travel. Provision is made, which can include power means for moving the water manifold away from and toward the stationary water supply conduit to accommodate the length of the coupled water carrying arm as it rotates around the connected riser. A method of continuously supplying water to a traveling sprinkler line is also disclosed.
