Description

Die Erfindung bezieht sich auf eine Beregnungsvorrichtung zur Beregnung viereckiger Flächen, bestehend aus einem Standfuss, einem vom Standfuss getragenen Antriebsgehäuse sowie einer im Antriebsgehäuse gelagerten rohrartigen Düse (Fächerdüse), mit einem vom zuströmenden Beregnungswasser angetriebenen Turbinenrad im Antriebsgehäuse, dessen mittels Untersetzungsgetriebe untersetzte Drehbewegung mit Hilfe eines Umwandlungsgetriebes in eine periodische Schwenkbewegung der um eine parallel zur Standebene des Standfusses verlaufende Achse (Schwenkachse) hin- und herschwenkbaren Fächerdüse umgewandelt ist, die nach Vollzug eines halben Schwenkwinkels eine senkrecht zur Standfläche stehende Richtung ihrer Abstrahlebene aufweist und mit Bezug auf die Richtung der Abstrahlebene relativ zur Standfläche des Standfusses derart verstellbar ist, dass die beregnete Fläche (Beregnungsfläche) ganz oder überwiegend links oder rechts der Symmetrieebene des Standfusses liegt.The invention relates to a sprinkling device for sprinkling square surfaces, consisting of a stand, a drive housing carried by the stand and a tubular nozzle (fan nozzle) mounted in the drive housing, with a turbine wheel driven by the inflowing irrigation water in the drive housing, the rotational movement of which is reduced by means of a reduction gear with the aid a conversion gear is converted into a periodic swiveling movement of the fan nozzle, which can be swiveled back and forth about an axis parallel to the standing plane of the foot (swiveling axis), which, after completion of a half swiveling angle, has a direction of its radiation plane that is perpendicular to the standing surface and with reference to the direction of the radiation plane is adjustable relative to the base of the base in such a way that the irrigated surface (irrigation surface) lies entirely or predominantly to the left or right of the plane of symmetry of the base.

Unter «Abstrahlebene» im obigen Sinne wird die Ebene der Wasserstrahlen verstanden, welche in einem bestimmten Augenblick, also in einer bestimmten Schwenkposition aus den linear an der Fächerdüse angeordneten Düsen austreten.The “radiation level” in the above sense means the plane of the water jets which emerge from the nozzles arranged linearly on the fan nozzle at a specific instant, that is to say in a specific pivoting position.

Bei bekannten Beregnungsvorrichtungen dieser Art (US-A-2 914 255; 4 245 786; 3269661) können unterschiedliche Beregnungsbereiche eingestellt werden. Diese werden vielfach mit «voll» - «mittel» - «links» - «rechts» bezeichnet. Die alternativen Einstellungen werden dadurch erreicht, dass die Fächerdüse unter Veränderung des Umwandlungsgetriebes mit Bezug auf die Richtung der Abstrahlebene relativ zur Standfläche des Standfusses verstellbar ist, wodurch sich zwangsläufig auch eine Änderung des Schwenkwinkels ergibt. Solche bekannte Beregnungsvorrichtungen setzen im übrigen Umwandlungsgetriebe voraus, die einen für die Bedienungsperson zur Einstellung zugänglichen Kurbeltrieb mit lösbarer Klemmeinrichtung umfassen. Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Beregnungsvorrichtung der eingangs genannten Gattung derart weiterzubilden, dass sie weniger störanfällig und mit Bezug der Verstellung der Abstrahlebene einfach zu handhaben ist.In known irrigation devices of this type (US-A-2 914 255; 4 245 786; 3269661) different irrigation ranges can be set. These are often referred to as "full" - "medium" - "left" - "right". The alternative settings are achieved in that the fan nozzle can be adjusted with respect to the direction of the radiation level relative to the base of the base while changing the conversion gear, which inevitably also results in a change in the pivoting angle. Such known irrigation devices also require conversion gearboxes which comprise a crank mechanism with a releasable clamping device which is accessible to the operator for adjustment. Proceeding from this, the object of the invention is to further develop a sprinkling device of the type mentioned in the introduction in such a way that it is less susceptible to faults and is easy to handle with reference to the adjustment of the radiation level.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass zur Lageverschiebung der Beregnungsfläche das die Fächerdüse tragende Antriebsgehäuse mit Hilfe eines Achszapfens im Standfuss in gegensätzlichen Schwenkrichtungen begrenzt schwenkbar und arretierbar gelagert ist.This object is achieved according to the invention in that, for the purpose of shifting the position of the sprinkling surface, the drive housing carrying the fan nozzle is mounted so that it can be pivoted and locked to a limited extent in opposite pivot directions with the aid of an axle pin in the base.

Eine solche Lösung hat zudem den Vorteil, dass die jeweilige Einstellung der Beregnungsvorrichtung bereits aus grösserer Entfernung erkennbar ist, was insbesondere für die bekannten Beregnungsvorrichtungen nicht zutrifft, weil aus der jeweiligen Klemmstellung des Kurbeltriebes nicht erkennbar ist, welche Lage der Beregnungsfläche zu erwarten ist. Insoweit entfällt auch in der Regel die insbesondere bei Export (Vielsprachigkeit) lästige Beschriftung des Regners mit Bezug auf die Betriebsstellung.Such a solution also has the advantage that the respective setting of the sprinkling device can already be seen from a greater distance, which is not the case in particular for the known sprinkling devices, because the position of the sprinkling surface is not to be seen from the respective clamping position of the crank mechanism. In this regard, the irritating labeling of the sprinkler with reference to the operating position, which is particularly annoying when exporting (multilingualism), is also omitted.

Bei einer solchen Ausbildung ist die jeweilige Einstellung der Beregnungsvorrichtung auch auf sehr grosse Entfernung erkennbar. Zudem wird bei Verstellung der Schwerpunkt zugunsten einer grösseren Standfestigkeit bzw. geringeren Fussabmessung verlagert, welch letzteres sich günstig auf die Fertigungskosten auswirkt.With such a design, the respective setting of the irrigation device can be seen even at a very great distance. In addition, the focus is shifted in favor of greater stability or smaller foot dimensions, which has a favorable effect on production costs.

Weitere Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further refinements of the invention result from the subclaims.

Nachstehend wird die Erfindung anhand eines Ausführungsbeispieles erläutert.The invention is explained below using an exemplary embodiment.

Im konkreten Ausführungsbeispiel der Figuren ist der Achszapfen 2b exzentrisch zur Mittelachse c-c des Antriebsgehäuses 2 sowie parallel und diametral zur Schwenkachse d-d angeordnet.In the specific exemplary embodiment of the figures, the journal 2b is arranged eccentrically to the central axis c-c of the drive housing 2 and parallel and diametrically to the pivot axis d-d.

Der Viereckregner umfasst einen Standfuss 5, ein vom Standfuss 5 getragenes, zylindrisches Antriebsgehäuse 2 sowie eine im Antriebsgehäuse 2 gelagerte rohrartige Düse 3 (Fächerdüse), die durch einen linearen Rohrabschnitt mit linear angeordneten Düsen oder aber auch durch einen gekrümmten Rohrabschnitt mit linear angeordneten Düsen (Düsenbogen) gebildet sein kann. Im Antriebsgehäuse ist ein vom zuströmenden Beregnungswasser angetriebenes Turbinenrad (in der Zeichnung nicht sichtbar) angeordnet, dessen mittels Untersetzungsgetriebe untersetzte Drehbewegung in eine periodische Schwenkbewegung der Fächerdüse 3 übersetzt ist.The square sprinkler comprises a pedestal 5, a cylindrical drive housing 2 carried by the pedestal 5 and a tubular nozzle 3 (fan nozzle) mounted in the drive housing 2, which nozzle nozzle has a linear pipe section with linearly arranged nozzles or else a curved pipe section with linearly arranged nozzles ( Nozzle arch) can be formed. A turbine wheel (not visible in the drawing) driven by the inflowing irrigation water is arranged in the drive housing, the rotational movement of which, by means of a reduction gear, is translated into a periodic pivoting movement of the fan nozzle 3.

Die Fächerdüse ist um eine parallel zur Standebene a-a des Standfusses 5 verlaufende Achse (Schwenkachse) hin- und herschwenkbar.The fan nozzle can be pivoted back and forth about an axis (pivot axis) running parallel to the standing plane a-a of the standing foot 5.

Wie aus den Figuren erkennbar, weist die Fächerdüse 3 nach Vollzug eines halben Schwenkwinkels a eine senkrecht zur Standfläche a-a stehende Richtung ihrer Abstrahlebene auf.As can be seen from the figures, the fan nozzle 3 has a direction of its radiation plane perpendicular to the standing surface a-a after completion of a half swivel angle a.

Über das Anschlussstück 1 wird der Turbine im Antriebsgehäuse 2 aus dem Schlauch 20 Druckwasser zugeführt. Das zylindrische Antriebsgehäuse 2 ist über einen hohlen Achszapfen 2b in einer Konsole 4 des Standfusses 5 schwenkbar gelagert, der exzentrisch zur Mittelachse c-c des Antriebsgehäuses 2 liegt.Pressurized water is supplied from the hose 20 to the turbine in the drive housing 2 via the connection piece 1. The cylindrical drive housing 2 is pivotally mounted via a hollow journal 2b in a bracket 4 of the base 5, which is eccentric to the central axis c-c of the drive housing 2.

In eingestellter Schwenkposition wird das Antriebsgehäuse nur durch Reibungskraft mittels Spannschraube 9 gehalten, welche mit der Gehäusewand 2a im Gewindeeingriff steht. Die Spannschraube ist ohne Lockerung unter Überwindung des Reibungswiderstandes in einem Sektorenausschnitt 10 der Konsole 4 verschiebbar. Für eine Rastkugel 11 ist in einer Mittelstellung gemäss Figur 2 in der Gehäusewand 2a eine Vertiefung 13 vorgesehen, in welche die Rastkugel 11 unter dem Druck einer Feder 12 merklich einrastet. Das Antriebsgehäuse 2 liegt dabei symmetrisch zum Standfuss 5. Die Schwenkbewegung der Fächerdüse 3 erstreckt sich nach links oder rechts jeweils über den halben Schwenkwinkel a.In the set pivot position, the drive housing is held only by frictional force by means of clamping screw 9, which is in threaded engagement with the housing wall 2a. The clamping screw is without loosening while overcoming the frictional resistance in one Sector section 10 of the console 4 can be moved. For a detent ball 11 in a central position according to FIG. 2, a recess 13 is provided in the housing wall 2a, into which the detent ball 11 noticeably engages under the pressure of a spring 12. The drive housing 2 is symmetrical to the base 5. The pivoting movement of the fan nozzle 3 extends to the left or right in each case over half the pivot angle a.

Die Figur 3 zeigt das nach rechts um den halben Winkel a geschwenkte Antriebsgehäuse 2. Bei dieser Einstellung kommt die um ihre Schwenkachse d-d schwenkbare Fächerdüse 3 in eine Betriebsstellung, bei welcher der Schenkel 14 des Winkels a in die vertikale Stellung überführt ist. Beregnet wird damit ausschliesslich die rechts von der Symmetrieebene b-b des Standfusses 5 befindliche Fläche. Analog hierzu zeigt Figur 4, wie das aus Antriebsgehäuse 2 und Fächerdüse 3 bestehende Aggregat nach links geschwenkt und damit der Schenkel 15 des Winkels a in eine vertikale Stellung gebracht werden kann. In dieser Position wird die Fläche links von der Symmetrieebene b-b des Standfusses 5 beregnet.FIG. 3 shows the drive housing 2 pivoted to the right by half the angle a. With this setting, the fan nozzle 3, which can be pivoted about its pivot axis d-d, comes into an operating position in which the leg 14 of the angle a is transferred to the vertical position. Only the surface to the right of the plane of symmetry b-b of the base 5 is irrigated. Analogously to this, FIG. 4 shows how the assembly consisting of drive housing 2 and fan nozzle 3 is pivoted to the left and thus the leg 15 of the angle a can be brought into a vertical position. In this position, the area to the left of the plane of symmetry b-b of the base 5 is irrigated.

Ausser der einfacheren Bedienung der bereits aus grösserer Entfernung sichtbaren Betriebseinstellung, hat die Verschwenkung des Antriebsgehäuses 2 noch den Vorzug einer Gewichtsverlagerung und einer grösseren Standfestigkeit bzw. den Vorzug der geringsten Fussabmessungen. Erläutert wird dies anhand von Figur 3: Die Düsen der Fächerdüse 3 bewirken eine Reaktionskraft N, die der Abstrahlrichtung der Wasserstrahlen 16 entgegengesetzt ist. Dabei interessiert vor allem die Standfestigkeit des Regners in den extremen Betriebsstellungen «links» oder «rechts». Durch die Schwenkachse d-d der Fächerdüse 3 (Stellung 17 in Figur 3) wirkt die resultierende Reaktionskraft N nach Figur 3. Sie erzeugt mit dem Hebelarm L, ein Drehmoment an der Fusskante 18, das im folgenden als Md1 bezeichnet wird. Dem entgegen wirkt das Gewicht G1 des Standfusses 5 mit dem Hebelarm L2 als Md2 und das Gewicht G2 des Regners 2 mit dem Hebelarm L3 als Md3. Damit muss also die Summe aus den Drehmomenten Md2 + Md3 grösser sein als Md,, wodurch eine gute Standfestigkeit gewährleistet ist. Dabei garantiert die Schwenkung ein minimales Drehmoment Mdi, indem die Schwenkachse d-d aus Stellung 19 (Figur 3) nach Stellung 17 gebracht und damit der zugehörige Hebelarm um die Länge L, auf die Länge L1 verkürzt wurde, und ein maximales entgegengesetztes Drehmoment, resultierend aus der Summe der Drehmomente Md2 und Md3, indem das Drehmoment Md3 um die Differenz der Strecken L3 - L, vergrössert wird.In addition to the simpler operation of the operating setting that is already visible from a greater distance, the pivoting of the drive housing 2 also has the advantage of a weight shift and greater stability or the advantage of the smallest foot dimensions. This is explained with reference to FIG. 3: the nozzles of the fan nozzle 3 produce a reaction force N which is opposite to the direction of radiation of the water jets 16. The stability of the sprinkler in the extreme left or right operating positions is of particular interest. The resulting reaction force N according to FIG. 3 acts through the pivot axis dd of the fan nozzle 3 (position 17 in FIG. 3). With the lever arm L, it generates a torque at the foot edge 18, which is referred to below as Md 1 . This is counteracted by the weight G 1 of the base 5 with the lever arm L 2 as Md 2 and the weight G 2 of the sprinkler 2 with the lever arm L 3 as Md 3 . So the sum of the torques Md2 + Md3 must be greater than Md, which ensures good stability. The pivoting guarantees a minimal torque Md i by moving the pivot axis dd from position 19 (FIG. 3) to position 17 and thus the associated lever arm has been shortened by the length L, to the length L 1 , and a maximum opposite torque resulting from the sum of the torques Md 2 and Md 3 , in that the torque Md 3 is increased by the difference between the distances L 3 - L.

Der Wasserzuführungsschlauch 20 wirkt mitseinem Gewicht zusätzlich stabilisierend auf den Regner. Entscheidend ist hierbei, dass er direkt unterhalb der Fächerdüse angeschlossen und ausgelegt ist. Es ist ausserdem so, dass die Fächerdüse 3 durch die Schwenkung des Antriebsgehäuses 2 mit Fächerdüse 3, also des Regners, nicht nur in die Betriebsstellung «LINKS» - «MITTE» - «RECHTS», sondern auch in jede dazwischenliegende Stellung gebracht werden kann. Die nach den Figuren 1-4 gezeigte Anordnung löst die Aufgabe mit einem Minimum an technischem Aufwand und stabilisiert den Viereckregner optimal.The weight of the water supply hose 20 also has a stabilizing effect on the sprinkler. It is crucial here that it is connected and designed directly below the fan nozzle. It is also the case that the fan nozzle 3 can be brought not only into the operating position “LEFT” - “CENTER” - “RIGHT”, but also into any position in between, by pivoting the drive housing 2 with the fan nozzle 3, ie the sprinkler. The arrangement shown in Figures 1-4 solves the task with a minimum of technical effort and optimally stabilizes the square sprinkler.

Im Ausführungsbeispiel ist der Achszapfen 2b exzentrisch zur Mittelachse c-c des Antriebsgehäuses 2 sowie parallel und diametral zur Schwenkachse d-d angeordnet.In the exemplary embodiment, the journal 2b is arranged eccentrically to the central axis c-c of the drive housing 2 and parallel and diametrically to the pivot axis d-d.

Anschliessend ist darauf hinzuweisen, dass eine bessere Standfestigkeit infolge Schwerpunktsverlagerung im Sinne des Ausführungsbeispieles z. B. auch dann erreichbar ist, wenn man die Schwenkachse des Antriebsgehäuses 2 mit der Schwenkachse d-d der Fächerdüse 3 zusammenfallen lässt. Dies setzt allerdings voraus, dass die Konsole 4 entsprechend nach oben verlängert ist.It should then be pointed out that a better stability due to a shift in the center of gravity in the sense of the embodiment example. B. can also be reached if the pivot axis of the drive housing 2 coincides with the pivot axis d-d of the fan nozzle 3. However, this presupposes that the console 4 is extended upwards accordingly.

Der Vorteil eines Stabilisierungseffektes ergibt sich auch für eine (nicht gezeichnete) Modifikation des Ausführungsbeispieles der Figuren, gemäss welcher die Fächerdüse konzentrisch zum Achszapfen 2b angeordnet ist. In diesem Falle ist es erforderlich das Beregnungswasser auf der der Fächerdüse gegenüberliegenden Seite des Gehäuses 2 zuzuführen.The advantage of a stabilizing effect also arises for a modification (not shown) of the exemplary embodiment of the figures, according to which the fan nozzle is arranged concentrically with the journal 2b. In this case, it is necessary to supply the irrigation water on the side of the housing 2 opposite the fan nozzle.
