Description

Die Erfindung betrifft eine Regneranordnung mit einer wasserdurchströmenden Antriebsvorrichtung sowie eine Bewässerungseinrichtung mit einer solchen Regneranordnung.The invention relates to a sprinkler arrangement with a water-flowing drive device and an irrigation device with such a sprinkler arrangement.

Zur Bewässerung insbesondere von Rasenflächen sind u.a. sogenannte Viereckregner gebräuchlich, welche einen um eine horizontale Schwenkachse oszillierend geschwenkten Regnerkopf mit einer Mehrzahl von Düsen und eine Antriebsvorrichtung in einem wasserdurchströmten Gehäuse aufweisen. Der Regnerkopf ist im Regelfall als Rohr oder langgestrecktes Gehäuse ausgeführt, welches an einem Ende bei der Antriebsvorrichtung und zusätzlich am anderen Ende von der Antriebsvorrichtung abgewandt in einem Sockel oder dergleichen gelagert ist, wie z.B. aus der DE 38 33 984 C2 bekannt. Die DE-PS 1912315 zeigt eine Beregnungsvorrichtung, bei welcher sich die Antriebsvorrichtung in einem wassergefüllten Gehäuse befindet, welches um eine horizontale Achse schwenkbar und in dessen Mantelfläche zugleich die Düsenanordnung ausgebildet ist.For irrigation in particular of lawns, inter alia, so-called square sprinklers are commonly used, which have an oscillating about a horizontal pivot axis sprinkler head with a plurality of nozzles and a drive device in a water-flowed housing. The sprinkler head is usually designed as a tube or elongated housing, which is mounted at one end in the drive device and in addition at the other end facing away from the drive device in a socket or the like, such as from DE 38 33 984 C2 known. The DE-PS 1912315 shows a sprinkler, in which the drive device is located in a water-filled housing, which is pivotable about a horizontal axis and in the lateral surface of which at the same time the nozzle assembly is formed.

Die DE 74 01 995 U1 zeigt einen Viereckregner, bei welchem der schwenkbare Regnerkopf eine mittige Zuleitung aufweist, die in eine zur Schwenkachse koaxiale Hohlwelle übergeht, welche an dem Ausgangsstutzen einer wassergetriebenen Turbine angeschlossen ist. Die Drehachse der Hohlwelle liegt seitlich gegen das Getriebe versetzt. Der Schwenkantrieb greift über ein Mehrhebelgelenk an einem der Zuleitungslagerung entgegengesetzten zweiten Schwenklager an.The DE 74 01 995 U1 shows a square sprinkler, wherein the pivotable sprinkler head has a central feed line, which merges into a coaxial to the pivot axis hollow shaft, which is connected to the outlet port of a water-driven turbine. The axis of rotation of the hollow shaft is offset laterally against the transmission. The pivot drive engages via a multi-lever joint on one of the lead storage opposite second pivot bearing.

Bei einer aus der US 3,498,543 bekannten Regneranordnung ist der Regnerkopf durch ein gekrümmtes Rohr gebildet, dessen Krümmung zur Veränderung des Beregnungsbildes variierbar ist. Da die Lagerung an den Rohrenden dadurch nicht mehr ohne weiteres möglich ist, ist das gekrümmte Rohr über eine Verbindungsleitung von der Antriebsvorrichtung her in der Rohrmitte gespeist. Die Lagerung des gekrümmten Rohrs erfolgt über die Verbindungsleitung an dem Antriebsgehäuse und einem Sockelgestell.At one of the US 3,498,543 Known sprinkler arrangement, the sprinkler head is formed by a curved tube whose curvature is variable to change the irrigation pattern. Since the storage at the tube ends is no longer readily possible, the curved tube is fed via a connecting line from the drive device ago in the middle of the tube. The storage of the curved tube via the connecting line to the drive housing and a base frame.

Die gattungsgemäße US-A-2 673 122 zeigt einen Rasensprenger mit einer um eine horizontale Achse schwenkbaren Düsenanordnung, welche gewölbt über einem Antriebsgehäuse verläuft und einseitig über eine von dem Antriebsgehäuse axial wegführende und in Richtung der Düsenanordnung umgelenkte Verbindungsleitung gespeist ist.The generic US-A-2 673 122 shows a lawn sprinkler with a pivotable about a horizontal axis nozzle assembly which is curved over a drive housing and is fed on one side via an axially away from the drive housing and deflected in the direction of the nozzle assembly connecting line.

Die DE 74 01 995 U1 beschreibt einen um eine horizontale Achse schwenkbaren Viereckregner, bei welchem von einer Antriebseinrichtung eine Verbindungsleitung axial wegführt und radial zu einer Düsenanordnung umgelenkt ist. Die Düsenanordnung ist durch einen sich axial beidseits der Verbindungsleitung erstreckenden Düsenkasten gebildet, der in einer konvex gewölbten Oberseite eine Reihe von Düsenöffnungen aufweist.The DE 74 01 995 U1 describes a quadrangular sprinkler pivotable about a horizontal axis, in which a connecting line axially leads away from a drive device and is deflected radially to a nozzle arrangement. The nozzle arrangement is formed by a nozzle box which extends axially on both sides of the connection line and has a row of nozzle openings in a convexly curved upper side.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine kompakte neue Regneranordnung sowie eine Bewässerungseinrichtung anzugeben.The present invention has for its object to provide a compact new sprinkler arrangement and an irrigation device.

Erfindungsgemäße Lösungen sind in den unabhängigen Ansprüchen beschrieben. Die abhängigen Ansprüche enthalten vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung.Solutions according to the invention are described in the independent claims. The dependent claims contain advantageous refinements and developments of the invention.

Die erfindungsgemäße Regneranordnung zeichnet sich bei modularer Bauweise mit Trennung von Regnerkopf und Antriebsgehäuse durch einen besonders kompakten Aufbau aus. Die Regneranordnung ermöglicht dadurch insbesondere auch eine Bewässerungseinrichtung mit einem in eine Bodenfläche, insbesondere eine Rasenfläche eingesenkten Schacht, welcher die Regneranordnung aufnimmt.The sprinkler arrangement according to the invention is distinguished by a particularly compact design in the case of a modular design with separation of sprinkler head and drive housing. The sprinkler arrangement thereby also makes possible, in particular, an irrigation device with a shaft which is sunk into a bottom surface, in particular a lawn, and which receives the sprinkler arrangement.

Der modulare Aufbau mit vom Gehäuse der Antriebsvorrichtung separiertem Regnerkopf ermöglicht den Einsatz von gebräuchlichen Antriebsvorrichtungen, insbesondere einer innerhalb einer Serie verschiedener Regneranordnungen einheitlichen Antriebsvorrichtung. Von besonderem Vorteil ist hierbei eine bevorzugte kreisrunde Querschnittsform des Antriebsgehäuses um die Schwenkachse, wodurch sich die Antriebsvorrichtung auch vorteilhaft für Kreis- oder Sektorenregner mit vertikaler Schwenkachse eignet.The modular design with separate rain head from the housing of the drive device allows the use of conventional drive devices, in particular a uniform drive device within a series of different sprinkler arrangements. Of particular advantage in this case is a preferred circular cross-sectional shape of the drive housing about the pivot axis, whereby the drive device is also advantageous for circular or Sektorregner with vertical pivot axis.

Die Antriebsvorrichtung besteht aus einem feststehenden und einem geschwenkten Teil, wobei vorzugsweise das Gehäuse der Antriebsvorrichtung feststehend ist und die Zuleitung um ein Ausgangselement, z.B. eine Hohlwelle, am Wasseraustritt um die Schwenkachse schwenkbar gelagert ist.The drive device consists of a fixed and a pivoted part, wherein preferably the housing of the drive device is stationary and the supply line around an output element, e.g. a hollow shaft, is pivotally mounted at the water outlet about the pivot axis.

Die wasserführende Verbindung zwischen dem wasserdurchströmten Antriebsgehäuse und dem Regnerkopf erfolgt über eine mit dem Regnerkopf starr verbundene Verbindungsleitung, welche bei feststehendem Antriebsgehäuse an oder in diesem schwenkbar gelagert ist. Der Regnerkopf stützt sich vorzugsweise über die starr verbundene Verbindungsleitung an dieser Verbindungsleitungslagerung gegen den Rückstoß bei der Strahlabgabe ab.The water-conducting connection between the water-flow drive housing and the sprinkler head via a rigidly connected to the sprinkler head connection line, which is pivotally mounted at a stationary drive housing or in this. The sprinkler head is preferably supported via the rigidly connected connecting line at this connecting line bearing against the recoil in the jet delivery.

Die Kompaktheit der Regneranordnung resultiert insbesondere daraus, dass der Schwerpunkt der Düsenanordnung als über alle Düsen einer mehrere Einzeldüsen enthaltenden Anordnung gemittelten Orts axial gegen die Position der Umlenkung der Verbindungsleitung in Richtung zur Antriebsvorrichtung hin versetzt ist. Insbesondere kann der Schwerpunkt der Düsenanordnung, welcher bei symmetrischem Aufbau der Düsenanordnung in deren geometrischer Mitte liegt, in axialer, d.h. zur Schwenkachse paralleler Richtung innerhalb des von dem Antriebsgehäuse eingenommenen Abschnitts liegen. Vorteilhafterweise liegt die Düsenanordnung vollständig gegen die axiale Extremposition der Umlenkung der Verbindungsleitung in Richtung des Antriebsgehäuses versetzt. Die Verbindungsleitung verläuft ab der Umlenkposition vorzugsweise radial senkrecht zur Schwenkachse. Die Düsenanordnung kann in axialer Richtung vorteilhafterweise vollständig in dem von Antriebsgehäuse und Verbindungsleitung eingenommenen Abschnitt liegen, so dass die axiale Baulänge der Regneranordnung durch die Düsenanordnung nicht erhöht wird.The compactness of the sprinkler arrangement results, in particular, from the fact that the center of gravity of the nozzle arrangement is offset axially relative to the position of the deflection of the connecting line in the direction of the drive device as a location averaged over all nozzles of an arrangement containing a plurality of individual nozzles. In particular, the center of gravity of the nozzle assembly, which lies in the geometric center of the nozzle assembly in the geometric center, in axial, i. lie to the pivot axis parallel direction within the occupied by the drive housing portion. Advantageously, the nozzle assembly is completely offset from the axial extreme position of the deflection of the connecting line in the direction of the drive housing. The connecting line extends from the deflection preferably radially perpendicular to the pivot axis. The nozzle arrangement can advantageously lie completely in the axial direction in the section occupied by the drive housing and connecting line, so that the axial length of the sprinkler arrangement is not increased by the nozzle arrangement.

Vorteilhafterweise verläuft die Verbindungsleitung mit einem Anfangsabschnitt am Strömungsausgang des Antriebsgehäuses in Richtung der Schwenkachse von dem Antriebsgehäuse weg und liegt in vorzugsweise radialer Richtung innerhalb des von dem Antrieb, insbesondere der Turbine des Antriebs eingenommenen Bereichs um die Schwenkachse. Der radiale Abschnitt der Verbindungsleitung zwischen dem Anfangsabschnitt und der Düsenanordnung liegt günstigerweise gegen das Antriebsgehäuse axial versetzt. Der Schwerpunkt der Düsenanordnung liegt hingegen wieder von dem radialen Abschnitt in Richtung des Antriebsgehäuses versetzt und vorzugsweise innerhalb der axialen Erstreckung des Antriebsgehäuses.Advantageously, the connecting line extends with an initial section at the flow outlet of the drive housing in the direction of the pivot axis away from the drive housing and lies in a preferably radial direction within the region occupied by the drive, in particular the turbine of the drive about the pivot axis. The radial portion of the connecting line between the starting portion and the nozzle assembly is conveniently axially offset from the drive housing. The focus of the nozzle assembly, however, is again offset from the radial portion in the direction of the drive housing and preferably within the axial extent of the drive housing.

Das Antriebsgehäuse weist zur Düsenanordnung hin vorteilhafterweise eine kreisbogenförmig um die Schwenkachse gewölbte Außenfläche auf. Die Düsenanordnung ist vorteilhafterweise radial außenliegend an einem wasserführenden relativ zum Antriebsgehäuse geschwenkten Düsengehäuse angeordnet. Der radiale Abstand des Düsengehäuses zum Antriebsgehäuse ist über den Schwenkbereich des Regners um die Schwenkachse vorteilhafterweise gering gegen den Radius des Düsengehäuses gegen die Schwenkachse, vorzugsweise geringer als 25 %, insbesondere geringer als 15 % dieses Radius. Die Düsenanordnung verläuft vorzugsweise im wesentlichen in konstantem Radius gegen die Längsachse parallel zu dieser.The drive housing advantageously has an arcuate arcuate outer surface curved toward the nozzle arrangement. The nozzle arrangement is advantageously arranged radially on the outside on a water-guiding nozzle housing pivoted relative to the drive housing. The radial distance of the nozzle housing to the drive housing is advantageously low over the pivoting range of the sprinkler about the pivot axis against the radius of the nozzle housing against the pivot axis, preferably less than 25%, in particular less than 15% of this radius. The nozzle arrangement preferably runs essentially in a constant radius against the longitudinal axis parallel to this.

Die Abstützung des Regnerkopfes kann entweder einseitig nur auf Seiten der Verbindungsleitung oder durch eine im Anschluss an die Düsenanordnung, der Verbindungsleitung axial abgewandte, insbesondere am entgegengesetzten Ende des Antriebsgehäuses angeordnete zusätzliche Lagerung um die Schwenkachse erfolgen.The support of the sprinkler head can be done either on one side only on the side of the connecting line or by a subsequent to the nozzle assembly, the connecting line axially remote, in particular arranged at the opposite end of the drive housing additional storage about the pivot axis.

Bei nur einseitiger Abstützung des Regnerkopfes ergibt sich eine Lagerung mit besonders geringem Kippmoment durch eine Düsenanordnung, deren Schwerpunkt axial zumindest annähernd mit der Position der Lagerung der Verbindungsleitung zusammenfällt, und vorzugsweise weniger als 50 % des Radius des Düsenschwerpunkts gegen die Schwenkachse axial von der Lagerung beabstandet ist. Dies ist insbesondere von Vorteil bei Düsenanordnungen mit einer axialen Länge von weniger als 50 % der axialen Erstreckung von Antriebsgehäuse plus Verbindungsleitung.With only one-sided support of the sprinkler head results in a bearing with a very low pitching moment by a nozzle assembly whose center of gravity coincides axially at least approximately with the position of the storage of the connection line, and preferably less than 50% of the radius of the nozzle center of gravity against the pivot axis axially spaced from the storage is. This is particularly advantageous in nozzle arrangements having an axial length of less than 50% of the axial extent of the drive housing plus the connection line.

Insbesondere bei axial längeren Düsenanordnungen kann die erwähnte zusätzliche Lagerung vorteilhaft sein, wobei dann günstigerweise der Düsenschwerpunkt in axialer Richtung zwischen der Verbindungsleitungs-Lagerung und der zusätzlichen Lagerung liegt. Eine vorteilhafte Ausführungsform sieht vor, dass die Länge der Düsenanordnung annähernd gleich der axialen Erstreckung von Antriebsgehäuse und Verbindungsleitung ist und insbesondere um weniger als 20 % von dieser axialen Erstreckung abweicht. Die zusätzliche Lagerung ist insbesondere von Vorteil zur Stabilisierung der Düsenanordnung gegen versehentliche externe Krafteinwirkung.Particularly in the case of axially longer nozzle arrangements, the mentioned additional storage may be advantageous, in which case the nozzle center of gravity advantageously lies in the axial direction between the connection line storage and the additional storage. An advantageous embodiment provides that the length of the nozzle arrangement is approximately equal to the axial extent of the drive housing and connecting line and in particular deviates by less than 20% from this axial extent. The additional storage is particularly advantageous for stabilizing the nozzle assembly against accidental external force.

Die Regneranordnung kann in an sich von Viereckregnern bekannter Weise mit Mitteln zur Veränderung des Regnerbilds ausgestattet sein. Insbesondere kann wenigstens ein Teil der Düsen des Regnerkopfs absperrbar oder veränderlich ausrichtbar sein.The sprinkler arrangement can be equipped with means for altering the sprinkler image in a manner known per se from square sprinklers. In particular, at least some of the nozzles of the sprinkler head can be shut off or variably alignable.

Durch die kompakte Bauweise kann die erfindungsgemäße Regneranordnung, deren Länge insbesondere weniger als 15 cm betragen kann, vorteilhaft in kleinvolumigen Schächten, welche in eine Bodenfläche eingesenkt sind, untergebracht werden und vorzugsweise in ein Bewässerungssystem mit unterirdisch verlegten Leitungen integriert werden. Durch mehrere geeignete verteilte Regneranordnungen können auch komplexer berandete Flächen gleichmäßig bewässert werden.Due to the compact design, the sprinkler arrangement according to the invention, the length of which may be in particular less than 15 cm, advantageously in small-volume shafts, which are sunk in a bottom surface, are housed and preferably integrated into an irrigation system with underground laid lines. By means of several suitable distributed sprinkler arrangements, even more complexly bounded surfaces can be irrigated uniformly.

In Fig. 1 ist eine Regneranordnung mit einem Regnerkopf RK, einer Antriebsvorrichtung AV in einem wasserdurchströmten Antriebsgehäuse GE und einer Verbindungsleitung VL zwischen Antriebsgehäuse und Regnerkopf als Teil einer besonders vorteilhaften Bewässerungseinrichtung in einen Schacht eingesetzt, dessen Schachtgehäuse SCH in eine Bodenfläche BF, insbesondere eine Rasenfläche eingesetzt ist. Die nach oben weisende Schachtöffnung SO ist durch einen Deckel DE abgedeckt, welcher um eine am Rand des Schachtgehäuses angeordnete Deckelachse DA nach oben schwenkbar ist, um für den Betrieb der Regneranordnung die Schachtöffnung freizugeben. Die Öffnung des Schachtdeckels erfolgt vorzugsweise bei Inbetriebnahme des Regners durch Zuführung von Wasser mit einem vorgegebenen Mindestdruck über eine Zuleitung ZL automatisch in der Weise, dass eine Betätigungsvorrichtung über einen Seitenkanal SK mit der Zuleitung ZL in Verbindung steht und einen unter der Einwirkung des Wasserdrucks verschiebbaren Kolben KO aufweist, welcher über eine mechanische Kopplung, im skizzierten Beispiel eine Schubgliederkette SG den Deckel DE öffnet, vorzugsweise entgegen einer schließend wirkenden Federkraft. Das über die Zuleitung ZL eintretende Wasser fließt über einen Filter FI und eine Eingangsleitung EL parallel zur Schwenkachse RA in das wasserdurchströmende Antriebsgehäuse AG und verlässt das Antriebsgehäuse am axial entgegensetzten Ende durch den achsparallelen Abschnitt VLA der Verbindungsleitung. Die Regneranordnung ist vorteilhafterweise um eine vertikale Drehachse DA in unterschiedlichen Drehpositionen ausrichtbar.In Fig. 1 is a sprinkler arrangement with a sprinkler head RK, a drive device AV in a water-flowed drive housing GE and a connecting line VL between the drive housing and sprinkler head as part of a particularly advantageous irrigation device inserted into a shaft whose shaft housing SCH is inserted into a bottom surface BF, in particular a lawn. The upwardly facing shaft opening SO is covered by a cover DE, which is pivotable about a lid shaft DA arranged on the edge of the shaft housing, in order to release the shaft opening for the operation of the sprinkler arrangement. The opening of the manhole cover is preferably carried out at startup of the sprinkler by supplying water with a predetermined minimum pressure via a supply line ZL automatically in such a way that an actuator via a side channel SK with the supply line ZL is in communication and a displaceable under the action of the water pressure piston KO, which opens the lid DE via a mechanical coupling, in the example shown, a push link chain SG, preferably against a closing force acting spring force. The entering via the supply line ZL water flows through a filter FI and an input line EL parallel to the pivot axis RA in the water flowing through drive housing AG and leaves the drive housing at the axially opposite end by the axis-parallel portion VLA of the connecting line. The sprinkler arrangement is advantageously alignable about a vertical axis of rotation DA in different rotational positions.

Der Regnerkopf RK ist starr mit der Verbindungsleitung VL verbunden. Insbesondere kann die Verbindungsleitung einstückig mit einem Düsengehäuse DG als Basisteil des Regnerkopfes ausgeführt sein, auf welches eine Düsenanordnung mit einer Mehrzahl von Einzeldüsen DU aufgesetzt sein kann. Die Verbindungsleitung VL weist einen Anfangsabschnitt VLA auf, welcher parallel zu der horizontalen Schwenkachse RA verläuft und in der Antriebsvorrichtung, insbesondere einer Ausgangsöffnung des Antriebsgehäuses GE gelagert ist. Die vorzugsweise als Zylinderfläche ausgebildete Gleitlagerfläche zwischen Antriebsgehäuse und Verbindungsleitung ist mit LV bezeichnet. Die mittlere Lagerposition dieser Lagerung ist auf einer zur Richtung der Schwenkachse RA parallelen Koordinationsachse X mit XL angegeben.The sprinkler head RK is rigidly connected to the connection line VL. In particular, the connecting line can be designed in one piece with a nozzle housing DG as the base part of the sprinkler head, on which a nozzle arrangement with a plurality of individual nozzles DU can be placed. The connecting line VL has an initial section VLA, which runs parallel to the horizontal pivot axis RA and in the drive device, is mounted in particular an output opening of the drive housing GE. The preferably designed as a cylindrical surface sliding bearing surface between the drive housing and connecting line is designated LV. The middle storage position of this storage is indicated on a parallel to the direction of the pivot axis RA coordination axis X with XL.

Die Verbindungsleitung VL weist außerhalb des bei XG endenden Antriebsgehäuses GE eine Umlenkung VLQ quer, vorzugsweise senkrecht, zur Schwenkachse RA auf und führt zu dem von der Regnerachse RA beabstandet liegenden Regnerkopf RK. Die axiale Extremposition der Verbindungsleitung von dem Antriebsgehäuse abgewandt sei mit XV bezeichnet.The connecting line VL has outside of the end at XG drive housing GE a deflection VLQ transversely, preferably perpendicular to the pivot axis RA and leads to the spaced apart from the sprinkler axis RA rain head RK. The axial extreme position of the connecting line facing away from the drive housing is denoted by XV.

Der quer zur Schwenkachse wegführende Abschnitt VLQ der Verbindungsleitung liegt vorteilhafterweise dicht an dem Antriebsgehäuse GE an und schließt in dem skizzierten Beispiel unmittelbar an einen Lagerstutzen mit dem Gleitlager LV an das Antriebsgehäuse an. Zwei Stellringe SR zur Einstellung von Schwenkwinkelgrenzen umgeben den Lagerstutzen radial.The transverse leading to the pivot axis section VLQ of the connecting line is advantageously close to the drive housing GE and includes in the example sketched directly to a bearing support with the sliding bearing LV to the drive housing. Two adjusting rings SR for adjusting the swivel angle limits surround the bearing neck radially.

Die Düsenanordnung mit einer Mehrzahl von Einzeldüsen DU liegt im skizzierten Beispiel bezüglich der axialen Extremposition XV des Abschnitts VLQ der Verbindungsleitung VL vollständig auf der dem Antriebsgehäuse zuweisenden Seite, kann aber auch in geringem Maß in Gegenrichtung über den Abschnitt VLQ hinausragen. Wesentlich ist, dass die Position XS des Schwerpunkts der Düsenanordnung, definiert als Mittelwert der Orte aller Einzeldüsen, bei ungleichen Düsenquerschnitten evtl. noch gewichtet mit relativen Düsenquerschnittswerten, in x-Richtung von der Umlenkung der Verbindungsleitung, insbesondere deren mittlerer Position XM in Richtung des Antriebsgehäuses versetzt und innerhalb des von dem Antriebsgehäuse eingenommenen Abschnitts GA liegt. Im skizzierten bevorzugten Beispiel liegt XM zumindest annährend in der Mitte zwischen XG und XV.The nozzle arrangement with a plurality of individual nozzles DU is in the example outlined with respect to the axial extreme position XV of the section VLQ of the connecting line VL completely on the side facing the drive housing, but may also protrude to a slight extent in the opposite direction over the section VLQ. It is essential that the position XS of the center of gravity of the nozzle arrangement, defined as the mean value of the locations of all individual nozzles, with different nozzle cross sections, possibly weighted with relative nozzle cross-section values, in the x-direction of the deflection of the connecting line, in particular their mean position XM in the direction of the drive housing offset and within the assumed occupied by the drive housing portion GA. In the preferred example outlined, XM is at least approximately midway between XG and XV.

Die Länge LD der Düsenanordnung ist im skizzierten Beispiel ungefähr gleich der Gesamtlänge von Verbindungsleitung, Antriebsgehäuse und Eingangsleitung EL, wobei letztere auch seitlich in das Antriebsgehäuse münden könnte oder als Bestandteil des Antriebsgehäuses betrachtet werden oder ausgeführt sein kann.The length LD of the nozzle assembly is in the example outlined approximately equal to the total length of connecting line, drive housing and input line EL, the latter could also open laterally into the drive housing or can be considered as part of the drive housing or executed.

Die Außenfläche des Antriebsgehäuses ist vorteilhafterweise, zumindest in einem dem Düsengehäuse DG zugewandten Abschnitt über den Schwenkbereich des Regnerkopfes, im wesentlichen kreisbogenförmig um die Schwenkachse gewölbt mit einem Radius RG um die Schwenkachse RA. Die Radiusdifferenz zu dem Radius RS des Düsengehäuses bezüglich der Schwenkachse RA ist klein gegenüber dem Radius, vorzugsweise (RS-RG) <0,25 RG insbesondere (RS-RG) <0,15 RG.The outer surface of the drive housing is advantageously, at least in a nozzle housing DG facing portion over the pivot region of the sprinkler head, substantially arcuately curved around the pivot axis with a radius RG about the pivot axis RA. The radius difference to the radius RS of the nozzle housing with respect to the pivot axis RA is small compared to the radius, preferably (RS-RG) <0.25 RG in particular (RS-RG) <0.15 RG.

Der Regnerkopf RK ist an seinem der Verbindungsleitung abgewandten Ende in einer zusätzlichen Lagerung am Antriebsgehäuse GE bzw. der mit diesem fest verbundenen Eingangsleitung EL abgestützt, indem ein Lagerbügel LA an einem auf der Schwenkachse RA liegenden Gehäusenocken NO schwenkbar gelagert ist.The sprinkler head RK is supported at its end facing away from the connecting line in an additional bearing on the drive housing GE or the fixedly connected thereto input line EL by a bearing bracket LA is pivotally mounted on a lying on the pivot axis RA housing cam NO.

Die Antriebsvorrichtung kann in an sich bekannter Weise aufgebaut sein und insbesondere eine richtungsumschaltbare Turbine, ein drehmomentübersetzendes Getriebe und ein mit dem Abschnitt VLS der Verbindungsleitung drehgekoppeltes Ausgangsrad umfassen. Die Turbine TU nimmt quer zur Schwenkachse RA bzw. der hierzu parallelen Turbinenachse typischerweise einen erheblichen Anteil des Querschnitts des Antriebsgehäuses ein. Vorzugsweise ist die Querausdehnung des Antriebsgehäuses senkrecht zur Schwenkachse geringer als der doppelte Durchmesser der Turbine. Die Schwenkachse RA verläuft vorzugsweise durch die Querschnittsfläche der Turbine.The drive device can be constructed in a manner known per se and, in particular, comprise a direction-reversible turbine, a torque-transmitting gear and a output gear rotationally coupled to the section VLS of the connecting line. The turbine TU takes transversely to the pivot axis RA or the turbine axis parallel thereto typically a significant proportion of the cross section of the drive housing. Preferably, the transverse extent of the drive housing perpendicular to the pivot axis is less than twice the diameter of the turbine. The pivot axis RA preferably extends through the cross-sectional area of the turbine.

Die Draufsicht der Fig. 2 auf die Bewässerungseinrichtung nach Fig. 1 veranschaulicht in anderem Blickwinkel weiter die vorstehenden Ausführungen. Das Schachtgehäuse SCH ermöglicht durch seine Form vorteilhafterweise eine veränderliche Ausrichtung der Schwenkachse RA um die Drehachse DA wie durch die Pfeile VR angedeutet ist. Das Schachtgehäuse ist vorzugsweise innen rund. Die Düsenanordnung kann abweichend von einer gebräuchlichen linearen Düsenzeile auch wie skizziert eine zentrale Düsenplatte mit zweizeiliger Anordnung von Einzeldüsen umfassen, welche beidseitig parallel zur Schwenkachse fortgeführt ist durch je einen einzeiligen Abschnitt. In den einzeiligen Abschnitten können die einzelnen Düsen durch Klemmschieber KS individuell abklemmbar sein.The top view of Fig. 2 on the irrigation device Fig. 1 Figure 3 illustrates, in another aspect, the foregoing. The shaft housing SCH allows by its shape advantageously a variable orientation of the pivot axis RA about the axis of rotation DA as indicated by the arrows VR. The shaft housing is preferably round inside. Deviating from a common linear nozzle line, the nozzle arrangement may also comprise, as outlined, a central nozzle plate with a two-row arrangement of individual nozzles, which is continued on both sides parallel to the pivot axis by a single-line section. In the single-line sections, the individual nozzles can be individually clamped by clamping slide KS.

In Fig. 3 ist eine Regneranordnung mit einem gegenüber Fig. 1 und Fig. 2 kurzen Regnerkopf RK3 in Seitenansicht und in Fig. 4 in Draufsicht skizziert, die insbesondere zur Beregnung kleiner Flächen vorteilhaft und z.B. in Verbindung mit einem Tropfbewässerungssystem besonders günstig ist. Die Länge LD3 der Düsenanordnung ist hier wesentlich geringer als die Gesamtlänge von Antriebsgehäuse GE (mit Eingangsleitung EL) und Verbindungsleitung VL. Der Regnerkopf RK3 ist nur über die Lagerung LV (Fig. 1) der Verbindungsleitung im Antriebsgehäuse abgestützt. Die Position XS3 des Düsenschwerpunkts des Regnerkopfs RK3 liegt vorteilhafterweise zumindest annähernd bei der Position der Lagerung der Verbindungsleitung, hier als Lagerungsabschnitt XL einer Gleitlagerung wie zu Fig. 1 skizziert und erläutert. Eine eventuelle Abweichung der Positionen XS3 und XL ist vorzugsweise geringer als RD/2 mit RD als Achsabstand der Düsenaustritte von der Schwenkachse RA.In Fig. 3 is a sprinkler arrangement with one opposite Fig. 1 and Fig. 2 short sprinkler head RK3 in side view and in Fig. 4 outlined in plan view, in particular for irrigation small areas advantageous and, for example, in connection with a drip irrigation system is particularly favorable. The length LD3 of the nozzle arrangement is substantially smaller than the total length of drive housing GE (with input line EL) and connecting line VL. The sprinkler head RK3 is only accessible via the bearing LV ( Fig. 1 ) of the connecting line supported in the drive housing. The position XS3 of the nozzle center of gravity of the sprinkler head RK3 is advantageously at least approximately at the position of the bearing of the connecting line, in this case as a bearing section XL of a plain bearing, as is the case Fig. 1 sketched and explained. A possible deviation of the positions XS3 and XL is preferably less than RD / 2 with RD as center distance of the nozzle exits from the pivot axis RA.

Das Antriebsgehäuse GE ist im Beispiel nach Fig. 3 und Fig. 4 auf einem Sockel RF montiert, welcher einen seitlichen Zufluss ZL3 und Abfluss AL3 zum Einsatz entlang einer durchgehenden Leitung sowie Befestigungslaschen zur Montage oder Aufstellung auf einer Befestigungsfläche aufweist.The drive housing GE is in the example after FIG. 3 and FIG. 4 mounted on a base RF, which has a lateral inflow ZL3 and outflow AL3 for use along a continuous line and mounting tabs for mounting or installation on a mounting surface.

Die Erfindung ist nicht auf die beschriebenen Ausführungsbeispiele beschränkt, sondern im Rahmen fachmännischen Könnens in mancherlei Weise abwandelbar. Die vorstehend und in den Ansprüchen angegebenen sowie die den Abbildungen entnehmbaren Merkmale sind sowohl einzeln als auch in verschiedener Kombination realisierbar.The invention is not limited to the exemplary embodiments described, but can be modified in many ways within the scope of expert knowledge. The features indicated above and in the claims and the figures which can be taken from the figures can be implemented both individually and in various combinations.
