Abstract
A rigid mount orbiter sprinkler assembly incorporates a deflector plate configuration that is configured for both spinning/rotating motion as well as orbital or wobbling motion around the center of a spool assembly. The sprinkler incorporates structure to reduce drool that may fall in a concentrated area below the sprinkler and to prevent debris from sandy water or the like from accelerating sprinkler component wear. With reduced vibration, the assembly may be rigidly mounted on a center pivot or other supporting structure while achieving the advantages associated with wobbling and rotating sprinkler assemblies.
Claims16
A sprinkler comprising:
- a sprinkler body;
- a nozzle associated with one end of the sprinkler body;
- a cap secured to or integral with an opposite end of the sprinkler body, the cap including a central opening;
- a deflector plate assembly supported by the cap and including a deflector plate at an upstream end facing the nozzle, a spool assembly supported in the central opening of the cap, and a counterbalance weight at a downstream end, wherein the deflector plate assembly is pitched at an angle relative to the sprinkler body, and wherein the counterbalance weight is disposed in a housing coupled with a distal end of the spool assembly,
- wherein the cap comprises contact surfaces surrounding the central opening on both sides thereof, and wherein the spool assembly comprises a pair of flanges positioned on opposite sides of the cap, the pair of flanges engaging the contact surfaces of the cap, respectively;
- and
- a cover positioned over the deflector plate assembly and secured to the sprinkler body, the cover including a pitch member disposed facing the housing, wherein the housing comprises a tab member at a distal end, the pitch member and the tab member cooperating to pitch the deflector plate assembly at the angle relative to the sprinkler body.
