    摘要： A high-volume sprinkler head includes a barrel with a nozzle; a fixed portion and a relatively movable portion adapted for pivoting movement relative to the fixed portion. The barrel is mounted on an upper support base rotatable on a lower stationary base in opposite directions through an arc about a vertical axis. A fluid-operated actuator pivots the relatively movable portion of the barrel relative to the fixed portion of the barrel between first and second reaction angles that cause the barrel and the annular upper support base to rotate in opposite directions, about the substantially vertical axis, respectively, when a stream is emitted from the nozzle. A three-way valve in combination with adjustable stops on the stationary base may be used to pilot the actuator, with the adjustable stops determining the arcuate extent of the rotational movement of the sprinkler head.

    摘要： A linear water feed apparatus for use in agricultural irrigation includes a linear-move machine with a mobile truss assembly supporting a plurality of individual sprinklers and adapted for movement in a specified direction across a field to be irrigated. The truss assembly is oriented transverse to the specified direction, and a supply pipe is arranged in the specified direction along or within the field to be irrigated. The supply pipe mounts a plurality of water supply hydrants at spaced locations along the pipe, each of the hydrants enclosing a water supply valve. A docking station is supported at one end of the truss assembly closest to the supply pipe, and is adapted to engage and open successive ones of the water supply valves in the plurality of hydrants. The docking station assembly includes a docking station that is suspended from a frame for floating movement about at least three mutually perpendicular axes.
