Abstract
An irrigation sprinkler includes a riser and a nozzle turret rotatably mounted at an upper end of the riser. A drive assembly is supported in the riser and is coupled to the nozzle turret for rotating the nozzle turret. The drive assembly has a reversing planetary gear drive, a reversing mechanism, and a manually adjustable arc setting mechanism including a pair of arc tabs. A position of one of the arc tabs is adjustable through the arc setting mechanism to change a size of an angle through which the nozzle turret oscillates back and forth. The manually adjustable arc setting mechanism is further adjustable to allow the nozzle turret to continuously rotate.
Claims20
An irrigation sprinkler of the type having a reversing planetary gear drive, comprising:
- a riser;
- a nozzle turret rotatably mounted at an upper end of the riser;
- a drive assembly supported in the riser and coupled to the nozzle turret for rotating the nozzle turret, the drive assembly having a reversing planetary gear drive, a reversing mechanism, and a manually adjustable arc setting mechanism including a pair of arc tabs, a position of one of the arc tabs being adjustable through the arc setting mechanism to change a size of an angle through which the nozzle turret oscillates back and forth, the manually adjustable arc setting mechanism further being adjustable wherein the manually adjustable arc setting mechanism includes an adjustable arc tab that is radially deflectable relative to a central axis of the sprinkler so that a shift toggle of the reversing mechanism cannot contact the adjustable arc tab to thereby allow the nozzle turret to continuously rotate.
A sprinkler, comprising:
- a riser;
- a nozzle rotatably mounted at an upper end of the riser;
- a drive assembly mounted in the riser for rotating the nozzle, the drive assembly having a reversing planetary gear drive, a reversing mechanism, and a manually adjustable arc setting mechanism that cooperates with the planetary gear drive and the reversing mechanism to allow the sprinkler to operate in an adjustable arc oscillation mode or alternatively in a uni-directional mode, wherein the manually adjustable arc setting mechanism includes an adjustable arc tab that is radially deflectable relative to a central axis of the sprinkler so that a shift toggle of the reversing mechanism cannot contact an adjustable arc tab to thereby allow the nozzle to continuously rotate.
