Title (EN) A SELF-PROPELLED IRRIGATOR
(FR) ARROSEUR AUTO-PROPULSE
Abstract:
(EN) 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.
(FR) Un arroseur auto-propulse comprend une bobine autour de laquelle est enroule un tuyau. L"eau arrivant par le tuyau alimente les chambres (p) d"une roue motrice (a) et sortant par une sortie d"eau (i) situee en face du plan vertical, diametral de la roue motrice lorsque l"on regarde dans le sens de deplacement. Les chambres sont definies par des parois laterales dans la roue motrice (a) et des cloisons reliant lesdites parois. Les cloisons sont incurvees en arriere dans le sens de rotation par rapport aux rayons de la roue et forment des plaques de guidage qui guident l"eau debordant d"une chambre superieure remplie et, se deversant dans la chambre precedente pour accumuler l"energie motrice. Les chambres comprennent des fentes etroites d"entree formant des reducteurs d"ecoulement de l"eau s"ecoulant des chambres passant dans la moitie arriere de la roue. De cette maniere, ces chambres qui ne sont pas encore videes produisent l"effet de freinage necessaire sur des terrains a forte declivite.
