Support structure for land irrigation system

摘要

A land irrigation system is illustrated in which an elongated sprinkler line continuously travels in a direction transverse to its length along the length dimension of a stationary water main and is continuously supplied with water from upstanding hydrants spaced along the length of the water main. A driven tractor moves along the water main at substantially the same rate as the sprinkler line and a plurality of elongated water carrying pipe connector devices each have one end portion connected to the sprinkler line and their other end portion movable into position for automatic connection to and disconnection from successive hydrants along the water main, to permit substantially continuous movement of the trctor along the water main and movement of the respective water carrying connector pipe devices into position for connection to the hydrants. An improved I-shaped track provides free roller movement of the end portion of the respective water carrying connector pipes which is connected to the sprinkler line.
