<p>Sewage agitating apparatus comprises a propeller-agitator arranged on an agitating tube or shaft 16 in which an axially extending row of holes 34 are provided, a pinion 32, engages the row of holes, and the pinion is supported on a driving sleeve 24 which is rotatably supported in a housing 18. The driving sleeve 24 which is connected to a motor 36 and surrounds the shaft 16, and drives the agitating shaft by way of gearing the pinion 32 is hand actuated for lowering and elevating the agitating shaft 16. The pinion 32 is rotatably supported on the attachment of the driving sleeve 24, and is provided with a locking mechanism. A stationary supporting tube 20 is mounted on the housing 18, and extends upwards above the pinion 32 and is provided with a bearing for the agitating shaft 16 at its upper end. The bearing and the pinion 32 are spaced from one another so that the agitating shaft is provided with greater rigidity. Thus, long agitating tubes or shafts can be used to agitate in cesspools having a great depth. The agitating tube can be rotated with greater speeds, so that propelling screws with a lower diameter can be used. <IMAGE></p> |
