Definitions

  • the invention relates to a sprinkling device according to the preamble of claim 1 or 6. It can be used, for example, as a portable or stationary device for sprinkling on lawns, beds or the like.
  • the water-carrying main channel forms the supporting body for the spray nozzle housing, only this main channel being held in a carrier and in turn bearing the entire weight of the spray nozzle housing by means of support and screw connections.
  • the invention has for its object to avoid disadvantages of known designs, in particular to create a sprinkling device of the type mentioned, which makes it possible in a simple manner to limit the water flow within relatively narrow limits to precisely defined areas with a compact design.
  • a separate main channel is assigned to the spray nozzle housing for the water flow between a line connection and the spray nozzles, the clear cross sections of which are essential or in many cases can be smaller than those of the housing and against which the rest of the spray nozzle housing is preferably sealed or sealable, so that the housing above all the function of a support profile or support housing z.
  • the weight of the irrigation device can also be kept very low during operation because of the small volume of its water supply, and in addition, when the irrigation device is started up, i.e. at the start of the water supply, the pressure at the spray nozzles builds up very quickly or practically immediately, because not before the entire housing must be filled with water and vented through the spray nozzles.
  • Another advantage is that the relatively narrow main channel is much easier to seal against unwanted water leakage than a relatively large-volume housing, especially since the flow cross-section of the main channel is at least at its narrowest points in the order of magnitude of that of the connection for the water pipe or even smaller can.
  • the irrigation device has spray nozzles which, for. B. are provided in at least one row in a row on a nozzle holder.
  • the nozzle carrier which could be formed by a curved pipe section or the like, is preferably designed as a housing with different internal and / or external cross-sections and has a water supply for supplying the water to the spray nozzles, so that targeted irrigation is ensured.
  • the spray nozzle housing can form at least over a part of its length substantially over its entire inner cross-section the associated section of the water guide in such a way that the housing is practically completely filled with water under pressure and that this water comes directly from the Housing enters the spray nozzles, which are formed by nozzle openings in a housing wall of the spray nozzle housing.
  • the irrigation device has proven itself well in operation, especially since the spray nozzle housing is also suitable for accommodating a swivel drive, with which the water curtain emerging from the spray nozzles can be pivoted back and forth to sprinkle a correspondingly large base area.
  • the main channel could protrude beyond the housing in the longitudinal direction of the housing with at least one end, be at least partially outside the housing transversely to this longitudinal direction or be provided entirely on the outside of the housing and also be formed at least partially in one piece with the housing, but this results in a particular one advantageous embodiment if the main channel is formed on the one hand by a separate, self-contained assembly group and on the other hand is essentially completely within the spray nozzle housing. If the main channel has the spray nozzles z. B. in the sense that they belong to the assembly mentioned, the waterproof seal is further simplified.
  • the swivel drive, the z. B. has a hydraulic motor connected to the water supply with gearbox, as a separate unit in so far completely out of the water supply, as a motor or drive housing is only flowed through by the water in a defined way, but is not washed around on the outside by the water so that z. B. the transmission located within this separate drive housing does not run in the water, but in a sealed transmission chamber.
  • a water outlet connection on the drive housing is expediently connected to the main duct in a sealed manner via a connecting piece within the spray nozzle housing.
  • the invention is also based on the object of being able to influence the guidance of the water when leaving the spray nozzle housing in such a way that certain characteristics of the escaping water curtain, e.g. whose width, density or the like can be changed.
  • one or more spray nozzles have means by which they can be switched off individually or in groups at least partially, but preferably completely with regard to the water outlet, so that less of them are used during operation or no more water comes out. If the adjustable nozzles are provided at the front or rear end of the at least one row of spray nozzles, the width of the escaping water curtain can be effectively reduced by placing one or more of these end nozzles to adapt to the size of the base area to be irrigated, especially if these End nozzles are inclined in a fan shape obliquely outwards so that the width of the water curtain can be selected to be substantially greater than the length of the row of nozzles.
  • each spray nozzle can be closed with a separate valve which is essentially inside the spray nozzle housing and which is simple Slider valve can be actuated by a linear, approximately parallel to the emerging water supply and / or transverse or perpendicular to the housing axis movement.
  • shut-off devices for the spray nozzles can belong to the assembly of this main channel or their fixed parts can be formed in one piece with the main channel.
  • a separate handle is expediently provided, the handles for adjacent spray nozzles in the longitudinal direction of the row of nozzles one behind the other and from the outside of the housing can be directly accessible, so that they practically form an indication of the setting state of the sprinkling device, because based on their position, the closed or open state of the associated spray nozzle can already be recognized from a distance.
  • the irrigation device 1 according to FIGS. 1 to 14 has a thin-walled, plastic, and essentially two-part spray nozzle housing 2, the length of which is several times greater than its cross-sectional width and that between end supports 5, 6 of a stand 3 or in the region its ends is rotatably or pivotably mounted about an axis parallel to the standing plane and to its longitudinal central axis.
