PATENT OFFICE.

The present invention is a device for rain-like distribution of Liquids over an annular surface, whose special facility is the application a central axis or a central supply of water, generally a fixed one Makes pipe or hose connection with the necessary supply pipeline superfluous. Although there are known institutions that

ίο serve to water ring-shaped areas and which are placed on wheels or carts, are moved by reaction water wheels, which are connected to them by a gearbox and are also located on the trolley, and operated by the water to be supplied and distributed under pressure.

This arrangement, however, requires a connection to the irrigation device with the fixed supply pipe for the water ahead. The fixed feed pipe naturally forms the center to which the carriage connected to it by an articulated pipe connection or a hose moves around in a circle. This pipe or hose connection sweeps the space within the ring zone traveled by the car, so that on there is no room for any other objects or devices. Is this central space not free, i. H. it will be from someone else If the objects cannot be removed, it is not possible to use such rain sprinklers.

But they also work with a great deal of resistance, partly due to the uneven running surface (with lawn sprinklers), on the other hand due to the connecting pipe that has to be dragged along respectively the connection hose with the central water supply pipe is generated and only by application very high water pressure or, in the absence of this, by large amounts of water for the operation of the reaction wheels can.

The subject matter of the present invention is a device that is under Avoidance of these resistances can be operated with significantly lower water pressure, no connection with any central points, absolutely no connection with requires any points outside the area to be irrigated, not a fixed one Pipe connection with the inflow line requires the necessary water pressure itself

Claims (3)

and the lack of any central connections makes it possible to arrange several snap rings coaxially around one another when the systems are enlarged. The device is shown in the drawing in FIG. 1 in elevation and partial section and in FIG. 2 in plan view with the upper inflow channel partially broken away. 3 and 4 show other types of device in axial section, and FIG. 5 illustrates the connection of several snap rings to one another. The device consists of an annular tube a with any number of radially or almost radially positioned tubes b, c of any length, which are equipped with outlet openings for the liquid. This pipe system is movably mounted on an annular running rail d by means of rollers e, so that it can move about its vertical axis. At a certain height above the 'pipe α an open top, likewise annular channel f is arranged and connected to the former by any number of downpipes g. h is a supply pipe for the liquid to be distributed, and i are pedestals for supporting the ring track d. The outlet openings in the tubes b and c can be designed and directed in any way if they only serve the purpose of distributing the liquid evenly over the surface to be irrigated when the entire system is moved around its vertical axis. The whole system can now either be moved by some mechanical means, or the movement can be caused in a known manner by the action of exiting water jets. In the latter case, a certain number of openings must be directed in such a way that a reaction effect can occur, i.e. they must fall within the tangent of the circular motion, as shown for example in the case of outlet openings I. The liquid flowing in from h first reaches the annular channel f, is distributed there and enters the annular tube α through the connecting pipes g, in order to get from this into the distribution pipes b, c. The outlet openings, of course with the exception of the openings Z, which are directed tangentially for the purpose of driving the device, will advantageously be directed upwards so that the liquid is thrown up in fine jets, atomized and well distributed on the surface to be irrigated. The uniform rotation of the device ensures a thoroughly uniform irrigation. The advantages of the device are, as already indicated, that initially the central axis is omitted, so you can also irrigate annular areas where the center point cannot be used for the purpose of storing the device, and that you can finally zoom in the system can arrange a ring coaxially around the other. Such a coaxial arrangement of two rings is shown in plan in FIG. In the construction of the system according to FIG. 3, the lower ring pipe is omitted, so that the downpipes g merge directly into the radial distribution pipes b. Furthermore, there is a deviation from the first-described type in that the tubes c are also missing, but it is clear that these can also be attached to the tubes g without difficulty. The right and left side of Fig. 3 finally show two differences, namely on the right side to connect and stiffen the lower ends of the tubes g with each other a ring m made of angle iron (in its place of course any other suitable profile iron can be used ) • present, while the left side does not show such a connection. Crossing rods n serve to brace the tubes with one another. In the design according to FIG are connected by a ring 0 made of T-iron, the center bar of which is directed downwards. The central web of the T-iron, which runs on the rollers e, thus represents the running rail, which, contrary to the types described above, is not fixed, but movable. Instead of the T-iron, another suitable profile iron can of course also be used. Godfather τ-An Proverbs: 1.
