ABSTRACT:
A rotary irrigation system comprises a continuous length of irrigation pipe (10) having sprinkler heads (16) spaced along the length thereof, which pipe is connected at one end to a fixed upstanding water supply pipe and at the other end to a water reservoir (24). The water reservoir (24) is suspended on a lever arm (22) which is perpendicular to the irrigation pipe (10), said water reservoir being elevated from the ground when empty. The irrigation pipe (10) is supported at uniformly spaced intervals along its length by a plurality of wheels (20), said wheels having hubs (55) which receive said pipe and allow said pipe to rotate in one direction only. As the reservoir (24) gradually fills with water, said reservoir lowers to the ground and a torque is imparted to the irrigation pipe (10), said pipe being free to rotate in this direction. After the reservoir (24) reaches the ground, the water is released and the irrigation pipe (10) unwinds in the opposite direction. The unwinding acts to turn the wheels (20) and advance the pipe (10).
