Abstract
A self propelled sprinkler is disclosed. The sprinkler has a support body with a drive unit which drives two rear wheels. The drive unit is powered by water pressure supplied through a hose which is coupled to the drive unit via a hose coupler. The drive unit has a cylindrical drive chamber with circular impeller in fluid communication with the hose coupler. The impeller is rotated by the water pressure and is mechanically connected to a lateral shaft. The shaft is connected to the rear wheels. Reduction gearing from the impeller to the shaft governs the speed of the sprinkler. The reduction gearing is achieved through a series of sun gears, carrier disks and planet gears. The drive unit also has an outlet which has a socket which allows the exit of the pressurized water. The socket allows the insertion of any variety of sprinkler heads. Thus, the sprinkler allows a variety of water distribution patterns. The sprinkler is propelled by water pressure rotating the impeller and eventually the rear wheels.
