摘要:
A rotary sprinkler and sled base. The sled base has a main body with a pair of wings pivotally connected thereto at opposed sides. The wings permit compact storage when folded in and provide a wider footprint when folded out to make the sprinkler more stable. The sprinkler head has a water channel which permits the jets to be lower to the ground for increased sprinkler stability. The sprinkler has a plurality of different sized vertical jets to achieve a more uniform water distribution, the top jet spraying further from the sprinkler, the bottom jet spraying the closest. The sprinkler has deflection means. The deflector may be a manually adjustable to fix the maximum spray distance or the deflector may be connected to a cam follower which follows a deformable circular "roller coaster" cam surface to alter the maximum spray distance as the sprinkler rotates. The deflector assembly may also include means for reducing water flow to the all of the jets.

A rotary sprinkler comprising a base (10), a stem (18) mounted on the base for rotation relative thereto, the stem having an inlet (26) for receiving a pressurized water supply, a water discharge nozzle (28) mounted on the stem and being rotatable together therewith relative to the base, water driven drive apparatus for rotating the stem relative to the base, selectably positionable deflector apparatus (50) for engaging a stream of water emitted by the nozzle for determining the maximum radius of the stream, and cam apparatus for operating the deflector apparatus and including manually settable cam apparatus for selecting an overall size and pattern of sprinkler stream coverage, and second cam apparatus for determining the desired sprinkling pattern as a function of the azimuthal orientation of the nozzle.
摘要:
A rotary sprinkler of the impact type having a manually settable cam for both selecting and displaying an overall pattern size of sprinkler stream coverage. The cam comprises two concentric abutting surfaces, one coupled through a cam surface with a water stream deflector, the other being fixed relative to the sprinkler. The surfaces in combination indicate the pattern size.

Disclosed is a circular or sector sprinkler, a nozzle arrangement of which has a sprinkling range that can be modified in accordance with the angle of rotation. Said sprinkler includes a control cam which annularly surrounds the axis of rotation and which can be transformed into a non-planar shape by means of adjusting means distributed along the periphery. The adjusting means are designed as adjusting levers which can be vertically pivoted, at hinges, about horizontal pivot axes that extend tangentially to the axis of rotation, lie on a plane running perpendicular to the axis of rotation, and vertically support the control cam in discrete positions.

A sprinkler (10) for discharging liquid onto an area with a predetermined geometrically shaped perimeter whilst maintaining a substantially constant liquids precipitation over said area. The sprinkler comprises a housing (12) fitted with a flow chamber (13) accommodating a motor (50) for rotating a sprinkler head (16) mounted on the housing, the housing comprising a first nozzle (23) and a second nozzle (33), in flow communication with the outlet end of the flow chamber. The first nozzle fitted for discharging liquid at a substantially short range. The sprinkler further comprises a dynamic liquid deflector (60) associated with the second nozzle, and biased by an, array of biasing elements (74), each adapted to dynamically bias the liquid deflector to a predetermined angle, thereby determine a deflection angle thereof.

Bei einer Spritzvorrichtung (1) für Beregnungsanlagen, mit einer antreibbaren Spritzdüse (4), die verdrehbar an einer ortsfesten Zuführungsleitung (3) für das zu verspritzende Medium angebracht ist, ist zur Bildung eines rechteckigen Spritzbildes der Spritzdüse (4) eine Zuteileinrichtung (11) vorgeschaltet, mittels der die Menge des dieser jeweils zuzuführenden Spritzmediums in Abhängigkeit von der Stellung der Spritzdüse (4) regelbar ist. Aufgrund dieser Ausgestaltung ist es problemlos möglich, trotz der Rotationsbewegung der Spritzdüse (4) ein rechteckiges Spritzbild zu erzeugen, so daß auch rechteckige Flächen gleichmäßig zu bewässern sind.
