摘要： A gear drive assembly for a rotary sprinkler includes a drive housing in which a reduction gear train is enclosed. A turbine located beneath one end of the drive housing rotates the gear train through a turbine shaft that extends into the drive housing. An output shaft extends out of the other end of the drive housing for rotating the nozzle assembly of the rotary sprinkler. The drive assembly includes a relatively large water entry port which is screened by a filter screen having relatively small openings. The water entry port allow enough water to enter the drive housing upon initial pressurization of the sprinkler such that sand particles suspended in the water do not jam the output shaft or the turbine shaft. The openings in the filter screen prevent the entry of particles into the drive housing that would tend to jam or foul the reduction gear train.

摘要翻译： 用于旋转喷洒器的齿轮驱动组件包括驱动壳体，减速齿轮系围绕该驱动壳体。 位于驱动器壳体一端下方的涡轮通过延伸到驱动器壳体中的涡轮机轴转动齿轮系。 输出轴延伸出驱动壳体的另一端，用于旋转旋转式喷洒器的喷嘴组件。 驱动组件包括相对较大的进水口，其通过具有相对小的开口的过滤网筛选。 进水口允许足够的水在喷洒器的初始加压时进入驱动器壳体，使得悬挂在水中的砂粒子不会堵塞输出轴或涡轮轴。 过滤器屏幕中的开口防止颗粒进入驱动器壳体，这将容易堵塞或弄脏减速齿轮系。

摘要： An adjustable arc sprinkler nozzle comprises a nozzle body which has a plurality of radial channels for forming radial streams out of water flowing into the nozzle from a sprinkler body to which the nozzle is joined. A crown shaped deflector member includes a plurality of vertically extending fingers which operatively coact with the radial nozzle channels to restrict the amount of water flowing therethrough. A selectively operable adjusting member is cooperatively engaged with the deflecting member for moving the deflecting member vertically relative to the nozzle body to vary the position of the fingers relative to the channels to change the amount of water restriction imposed by the fingers on the water flowing through the channels, whereby the throw radius is selectively adjusted by vertical movement of the deflecting member. A selectively operable locking member, i.e. a locking cover or a two-position locking pin, is provided for preventing movement of the adjusting member to lock out any adjustment in the throw radius.

摘要翻译： 一种可调弧喷头包括喷嘴主体，该喷嘴主体具有多个径向通道，用于从喷嘴连接到喷洒器主体上的流入喷嘴的水中形成径向流。 冠形偏转器构件包括多个垂直延伸的指状件，其可操作地与径向喷嘴通道共同作用以限制流过其中的水量。 可选择性地操作的调节构件与偏转构件协作地接合，用于相对于喷嘴体垂直地移动偏转构件，以改变手指相对于通道的位置，以改变手指施加在流过水面上的水量限制 通道，由此通过偏转构件的垂直运动选择性地调节投掷半径。 提供了选择性操作的锁定构件，即锁定盖或两位置锁定销，用于防止调节构件的移动以锁定投掷半径中的任何调整。
