ABSTRACT:
An irrigation line gate is adapted to be connected between an upstream irrigation line and a downstream irrigation line of a mobile irrigation system to allow lateral movement of the irrigation line past a stationary obstacle in a direction perpendicular to the length of the line. The irrigation line gate comprises longitudinally-spaced upstream and downstream manifolds connected between upstream and downstream movable irrigation lines. Laterally-spaced retractable gate pipes extending between the manifolds are sequentially opened to clear an obstacle as the irrigation line passes the obstacle. Each gate pipe is supported adjacent one of the manifolds by a longitudinally-spaced pair of pipe support collars. Each pair of support collars receives one of the gate pipes therethrough for slidable movement between open and closed positions. The gate pipe is received at the other manifold by a receiving bell comprising a receiving ferrule and a tapered guide for guiding the end of the gate pipe into alignment with the receiving ferrule as the gate pipe is closed. Locking devices are included to selectively connect between the support collars and the gate pipes for preventing longitudinal movement of the gate pipes relative to the support collars when the gate pipes are closed.
