| abstract | ABSTRACT OF THE DISCLOSURE An agricultural irrigation system for operation along an elongated pressurized water main having sections of land adjacent opposite sides thereof. The water main includes spaced, normally closed, access valves. The irrigation system has a length of water delivery pipe to extend from the water main. Carts support the length of water delivery pipe for forward movement along the ground surface. There is a drive on the cart for moving the cart and water delivery pipe transverse to the delivery pipe. Water applicators are located along the delivery pipe for selective water application. The delivery pipe can be rotated to control the drive to rotate the length of water delivery pipe to a position along the water main from one side to an opposite side so that the same length of water delivery pipe may irrigate two sections of land. There are connectors on the delivery pipe for selectively connecting the delivery pipe to and opening the normally closed access valves. The connector includes a valve coupling on the delivery pipe for selective engagement with the individual access valves to open the valves such that water is delivered through the delivery pipe. The connector also has swing arms having a free swinging end mounting the coupling and a remaining end attached to one end of the traveling water delivery pipe to guide the coupling between access valves. A pivot mounts the swing arm to the water delivery pipe for angular movement. There are valve coupling travel devices to support and move the free swinging end of the swing arm, to transport the valve coupling between valves, and valve coupler rotation devices to allow horizontal rotation of the swing arm when connection is made to an access valve and the remaining swing arm end is carried forward by the delivery pipe. Delivery pipe positioners maintain the delivery pipe aligned with the main during forward travel of the delivery pipe and subsequent water application. A control associated with the valve coupling, valve coupling travel device, and delivery pipe positioner controls the uncoupling, travel, and coupling of the valve coupling along the series of access valves. |
