1. A spray oscillating control apparatus for sprinklers, comprising a sprinkling control assembly to actuate the swinging operation of a spray body into different angles wherein a gear train assembly with an impeller is mounted to the interior of the sprinkling control assembly, and a spray oscillating control apparatus is provided in linking mechanism with the gear train assembly;

  • the spray oscillating control apparatus is composed of a water duct having a plurality of inlet orifices defining thereon, and a spray control device having a linkage gear wheel at one end and a plurality of covering blocks extending at the other end thereof;

    the linkage gear wheel of the spray control device is directly meshed with one matched gear of the gear train assembly thereof, and the covering blocks thereof are precisely matched to the inlet orifices thereof;

    therefore, the linkage gear wheel and the covering blocks of the spray control device are actuated by the gear train assembly to rotate therewith in a gradual manner so as to switch the amount of water supply allowed to enter the inlet orifices thereof, and, thus, spray projected can oscillate rhythmically from far-to-near and near-to-far in distance, achieving an even distribution of the spray onto a lawn thereby.
