ABSTRACT:
An automated wheel move irrigation system. A structural fluid connection is mounted between a lateral pipeline and a carriage guided for movement along the length of a stationary water supply line in unison with field movement imparted to the lateral pipeline as it moves sequentially from one field setting to the next. The structural fluid connection provides a fluid conduit which selectively couples to water discharge valves along the supply line. An indexing assembly on the carriage properly locates the carriage with respect to a selected valve. Automatic controls located on the carriage are utilized to operate the carriage elements and the prime mover for the lateral pipeline in a repeatable sequence to automatically operate the sprinkler system. The water discharge valve comprises a spherical enlargement at the upper end of a vertical riser, housing a ball that opens or closes the valve in response to the water or in response to an actuating rod mounted on the carriage. The structural fluid connection includes a horizontal extension coaxial with the pipeline to permit the pipeline to move along its center axis relative to the fluid connection, as well as permitting relative rotation between the lateral pipeline and the extension. Hydraulic seals and an inflatable bladder within the overlapping portions of these cylindrical elements fix them to one another while stationary. Alternate guide arrangements for the carriage are shown as wheels which roll along opposed sides of the water supply line or a cable guided between adjacent risers and carrying the carriage. Alternate physical arrangements applicable to the design of the structural fluid connections are described and illustrated.
