A self-propelled irrigator comprising a reel on which a hose is wound up. The water supplied through the hose is fed into chambers (p) in a driving wheel (a) from a water outlet (i) located in front of the vertical, diametral plane of the driving wheel when seen in the moving direction. The chambers are defined by side walls in the driving wheel (a) and partitions connecting said walls. hese partitions are curved backwards in the direction of rotation relative to the wheel radii and form guiding plates guiding overflowing water from a filled upper chamber into the preceding chamber for accumulation of the driving power. The chambers comprise narrow inlet slots forming flow restrictors for water flowing out of the chambers carried over the rear alf of the wheel. As a result these chambers not yet emptied provide a braking effect necessary on hilly grounds. |
