Description

Die Erfindung betrifft eine Vorrichtung zum Versprühen einer Flüssigkeit, gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for spraying a liquid, according to the preamble of Claim 1.

Bei den vorbekannten Sprühvorrichtungen dieser Art, werden die Tropfen von einer Schleuderscheibe allseitig in einer Ebene senkrecht zu ihrer Drehachse abgeschleudert. Die Tropfen bilden durch Einwirkung der Schwerkraft einen sogenannten Sprühkegel, dessen Durchmesser durch die Drehzahl der Schleuderscheibe beeinflußbar ist. Zur Erreichung einer hinreichend feinen und gleichmäßigen Tropfengröße ist es erforderlich, die Schleuderscheibe mit sehr hoher Drehzahl von beispielsweise 10.000 bis 15.000 Umdrehungen pro Minute anzutreiben. Dabei kann zwar eine sehr gleichmäßige Tropfengröße von beispielsweise 35 µ erreicht werden, jedoch besitzt der beim Versprühen erzeugte Hohlkegel einen relativ großen Durchmesser von beispielsweise 100 bis 120 cm, was für viele Anwendungszwecke unerwünscht ist.In the previously known spray devices of this type the drops from a centrifugal disc on all sides in one Thrown plane perpendicular to its axis of rotation. The Drops form one by the action of gravity so-called spray cone, the diameter of which by the Speed of the centrifugal disc can be influenced. For Achieve a sufficiently fine and even Drop size, it is necessary to use the centrifugal disc very high speed of 10,000 to 15,000, for example To drive revolutions per minute. One can very uniform drop size of, for example, 35 µ can be reached, however, when spraying generated hollow cone a relatively large diameter of for example 100 to 120 cm, which for many Applications is undesirable.

In der Landwirtschaft werden derartige Vorrichtungen zum Belegen von Flächen mit Herbiziden verwendet. Um gezielt die Flächen zwischen Nutzpflanzenreihen behandeln zu können, ist es erforderlich, die Sprühbreite möglichst genau einzustellen und den Tropfenstrom möglichst exakt auf die Fläche zu richten.In agriculture, such devices are used for Covering areas with herbicides used. To be targeted treat the areas between crop rows can, it is necessary to spray the width as possible set precisely and the drop flow as precisely as possible to judge the area.

Eine gattungsgemäße Vorrichtung zum Versprühen einer Flüssgigkeit ist aus der FR-A-2 526 330 bekannt. A generic device for spraying a Liquid is known from FR-A-2 526 330.

Die rotierende Fläche ist teilweise von einem Gehäuse umhüllt und läßt über einen Teilumfang eine Öffnung frei. Zum Sammeln zurückgehaltener Tropfen weist sie ein Reservoir und einen Fließweg auf, in dessen Verlauf eine Pumpe vorgesehen ist, um die gesammelte Flüssigkeit wieder mit der zufließenden Flüssigkeit zu vereinigen.The rotating surface is partly from a housing envelops and leaves an opening over a partial circumference. Instructs them to collect retained drops Reservoir and a flow path, in the course of which a Pump is provided to restore the liquid collected to combine with the inflowing liquid.

Diese Pumpe, die die gesammelte Flüssigkeit zurückführt, ist als Konus eines rotierenden Körpers, der auch die rotierende Fläche umfaßt, ausgestaltet, wobei die Konusspitze in das am Boden des Gehäuses befindliche Reservoir eintaucht. Die Flüssigkeit wird aufgrund der Zentrifugalkraft durch die rotierende Konusoberfläche nach oben gefördert, wo sie im rechten Winkel zur Drehachse abgeschleudert wird. Bei dieser bekannten Vorrichtung ist ein stärkeres Neigen der Drehachse aus der Vertikalen nicht möglich, weil dann die Konusspitze nicht mehr in das Flüssigkeitsreservoir eintaucht.This pump that returns the collected liquid is the cone of a rotating body, which is also the comprises rotating surface, designed, the Cone tip into the one at the bottom of the housing Reservoir immersed. The liquid is due to the Centrifugal force through the rotating cone surface conveyed above where they are at right angles to the axis of rotation is thrown out. In this known device a greater inclination of the axis of rotation from the vertical is not possible because then the cone tip no longer in the Immersed liquid reservoir.

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs genannten Art zu schaffen, die auch bei stark geneigter Drehachse bis zur Horizontalen geeignet ist, die im Reservoir angesammelte Flüssigkeit wieder der rotierenden Fläche zuzuführen.The object of the invention is a device of the beginning to create the type mentioned, even at highly inclined Axis of rotation up to the horizontal is suitable, which in Reservoir accumulated fluid again rotating Feed area.

Diese Aufgabe wird bei einer gattungsgemäßen Vorrichtung durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Aufgrund der erfindungsgemäßen Anordnung der Pumpenscheibe, der Leitstege und der Rinne bzw. des Übergaberohrs kann die Flüssigkeit aus dem Reservoir in jeder beliebigen räumlichen Lage der Drehachse sicher auf die Innenseite der rotierenden Fläche gefördert werden, auch bei fast horizontaler Ausrichtung der Drehachse. Dadurch ist es möglich, einen eng begrenzten Bodenstreifen einer Plantage mittels nach unten gerichteter Sprührichtung gezielt zu besprühen. This object is achieved in a generic device solved by the characterizing features of claim 1. Due to the arrangement of the pump disc according to the invention, the guide bars and the gutter or the transfer pipe can Liquid from the reservoir in any spatial position of the axis of rotation safely on the inside of the rotating surface are promoted, even at almost horizontal alignment of the axis of rotation. That’s it possible a narrowly defined strip of soil from a plantation by means of the spray direction directed downwards spray.

Dadurch, daß die rotierende Fläche und die Förderfläche als Teile eines einzigen Rotationsteils ausgebildet ist, ist die Pumpe besonders günstig zu fertigen.The fact that the rotating surface and the conveying surface as Parts of a single rotating part is formed to manufacture the pump particularly cheap.

Durch die Maßnahme, daß die rotierende Fläche eine Drehachse aufweist, die im Betriebszustand um einen Winkel gegenüber der Horizontalen geneigt ist, wird erreicht, daß die Schwerkraft das Zurückführen der Flüssigkeit im Gehäuse erleichtert.By the measure that the rotating surface is a Has axis of rotation, which in the operating state by an angle is inclined to the horizontal, it is achieved that gravity returning the liquid in the housing facilitated.

Wenn die Öffnung verstellbar ausgebildet ist, kann beispielsweise durch Veränderung des Öffnungssektors auch der aus der Öffnung austretende gerichtete Strom der gewünschten Sprühbreite angepaßt werden. Wird die Lage der Öffnung verändert, kann beispielsweise nach oben gesprüht werden.If the opening is adjustable, can for example by changing the opening sector too the directed flow emerging from the opening desired spray width can be adjusted. Will the location of the Opening changed, for example sprayed upwards become.

Ein Absaugen von gesammelter Flüssigkeit nach Beenden der Sprüharbeiten wird dadurch erleichtert, daß der Vorrichtung eine Dosierpumpe zur Versorgung mit Flüssigkeit zugeordnet ist, deren Förderrichtung umkehrbar ausgebildet ist. Wenn sie darüber hinaus eine Leitung zur Zuführung von Flüssigkeit aufweist, die in dem Reservoir mündend angeordnet ist, dann kann in diesem Fall die vorgesehene Dosierpumpe durch Umkehren der Drehrichtung auch das Absaugen übernehmen.A suction of collected liquid after the Spraying is facilitated by the fact that the device assigned a dosing pump for the supply of liquid is, the conveying direction is reversible. If they also have a line for feeding Has liquid that opens into the reservoir is arranged, then the intended one in this case Dosing pump by reversing the direction of rotation that too Take over suction.

Die Erfindung wird in Zeichnungen erläutert, wobei weitere vorteilhafte Einzelheiten den Zeichnungen zu entnehmen sind. The invention is illustrated in drawings, with others advantageous details can be found in the drawings are.

Öffnung 4 kann durch Verstellen der Segmentschürzen 9 und 10 (Fig. 3) somit verändert werden. Dadurch kann die Sprühbreite beeinflußt werden. Wird die Öffnung durch Änderung des Deckels 6 beispielsweise nach oben verlegt, kann auch entgegen der Richtung der Schwerkraft gesprüht werden. Wichtig ist, daß das Reservoir 29 unten verbleibt. For the purpose of spray width adjustment are in the side Edge area within the opening 4 also around the axis 2 along two arcuate adjustment openings 17 (Fig. 3) slidable segment aprons 9 and 10 (Fig. 3) arranged. Opening 4 can be adjusted by Segment aprons 9 and 10 (Fig. 3) can thus be changed. This can affect the spray width. Will the Opening by changing the cover 6, for example after laid above, can also go against the direction of the Gravity sprayed. It is important that that Reservoir 29 remains below.

Antriebswelle 12 ist Teil eines geeigneten Motors 14.Pump disk 30 is coaxial with centrifugal disk 1 integrally formed and thereby with the drive shaft 12 Centrifugal disc firmly connected. Drive shaft 12 is part a suitable motor 14.

Mittels Stegen 15 ist das Schleuderrad 1 und die daran angeformte Pumpenscheibe 30 fest mit der Antriebswelle 12 verbunden.By means of webs 15, the centrifugal wheel 1 and the one on it molded pump disk 30 fixed to the drive shaft 12 connected.

Schließlich ist eine Zuführöffnung 16 vorgesehen, durch die zu versprühende Flüssigkeit in den vom Düsenkörper 5 und Deckel 6 gebildeten Gehäuse 3 geleitet wird. In diesem Raum läuft Pumpenscheibe 30 in Richtung des Pfeils 19 (Fig. 3) um.Finally, a feed opening 16 is provided through which Liquid to be sprayed into the nozzle body 5 and Cover 6 formed housing 3 is passed. In this room pump disc 30 runs in the direction of arrow 19 (FIG. 3) around.

In Figur 2 ist eine Ansicht auf das Innere des Düsenkörpers 5 mit Düsenfütterung gemäß Pfeilrichtung II in Figur 1 dargestellt. Gleiche Teile sind, wie in den übrigen Figuren, mit gleichen Bezugsziffern versehen. Stege 23, 24 innerhalb des Düsenkörpers 5 dienen zur Führung der Flüssigkeit.In Figure 2 is a view of the inside of the Nozzle body 5 with nozzle feeding according to arrow direction II in Figure 1 shown. The same parts are as in the rest Figures with the same reference numbers. Bridges 23, 24 inside the nozzle body 5 serve to guide the Liquid.

Zur Erläuterung des Fließweges einer zu versprühenden Flüssigkeit sind in Figur 2 zusätzlich Pfeile 28 dargestellt. Die Flüssigkeit wird über ein Leitungssystem durch die Zuführleitung 16 der inneren Ausnehmung des Düsenkörpers 5 zugeführt.To explain the flow path of a sprayed Liquid is additionally arrows 28 in FIG. 2 shown. The liquid flows through a pipe system through the feed line 16 of the inner recess of the Nozzle body 5 supplied.

Die durch Öffnung 16 zufließende Flüssigkeit wird in Richtung des Fließweges 27 der im Zentrum von Düsenkörper 5 angeordneten schnabelartig ausgebildeten halboffenen Rinne 13 geleitet, die an die Stege 24 angeformt ist. Von der Rinne 13 wird die Flüssigkeit dann der Innenseite der Schleuderscheibe 1 aufgegeben.The liquid flowing through opening 16 is in Direction of the flow path 27 in the center of the nozzle body 5 arranged beak-shaped semi-open Channel 13 passed, which is integrally formed on the webs 24. Of the groove 13, the liquid is then the inside of the Abandoned disc 1.

Durch die hohe Geschwindigkeit wird zugeführte Flüssigkeit von der äußeren Kante des Schleuderrades 1 abgeschleudert. Einzelne Tröpfchenwege sind durch die in gepunkteter Linienführung gezeichneten Pfeile 20 (Fig. 3) angedeutet. An dieser Ansicht ist besonders deutlich zu erkennen, wie durch Verstellen der Segmentschürzen 9 und 10 um Achse 2 in einer der Richtungen der Pfeile 21 die Sprühbreite der Rotationsdüsen verstellbar ist. Nach Einstellung der Sprühbreite sind Segmentschürzen 9 und 10 mittels Arretierschrauben 18 feststellbar.Due to the high speed, liquid is supplied hurled from the outer edge of the impeller 1. Individual droplet paths are dotted by the in Lines drawn arrows 20 (Fig. 3) indicated. This view shows how by adjusting the segment aprons 9 and 10 about axis 2 in one of the directions of arrows 21 the spray width of the Rotation nozzle is adjustable. After setting the Spray width are segment aprons 9 and 10 by means of Locking screws 18 lockable.

Über einen größeren Teil des Umfangs wird die abgeschleuderte Flüssigkeit von der zylindrischen Innenfläche des Deckels 6 (Fig. 3) aufgefangen. Dieser Teil der Flüssigkeit wird von Fläche 7 des Deckels 6 abgeleitet und fließt der Schwerkraft folgend in den unteren Gehäuseteil des Düsenkörpers 5, der von zylindrischer Fläche 8 gebildet wird und als Reservoir 29 dient. Die im Reservoir 29 gesammelte Flüssigkeit tritt durch Öffnung 22 in den Bereich der Pumpenscheibe 30, wo sie von der Pumpenscheibe 30 mitgenommen wird, um erneut über Rampe 25 entlang des mit Pfeil 26/28 gekennzeichneten Fließweges in den oberen Bereich gefördert zu werden, um über Schräge 11, Rinne 13 gemeinsam mit der zufließenden Flüssigkeit der Schleuderscheibe 1 zugeführt zu werden.Over a larger part of the circumference flung liquid from the cylindrical Inner surface of the cover 6 (Fig. 3) collected. this part the liquid is drained from surface 7 of cover 6 and flows into the lower one following gravity Housing part of the nozzle body 5, the cylindrical Surface 8 is formed and serves as a reservoir 29. The in Reservoir 29 liquid collected passes through opening 22 in the area of the pump disc 30, where it from the Pump disk 30 is taken to again via ramp 25 along the flow path marked with arrow 26/28 in the upper area to be conveyed over slope 11, Channel 13 together with the inflowing liquid Centrifugal disc 1 to be fed.

Die Figur 4 zeigt schematisch die Funktionsweise der Vorrichtung. Aus einem Behälter B wird mittels Dosierpumpe P1 von Leitung L1 ein Volumenstrom V1 angesaugt und der Schleuderscheibe 1 zugeführt. Von dort wird ein Teilvolumen V4 der gebildeten Tropfen abgeschleudert. Der Rest wird im Gehäuse 3 zurückgehalten und im Reservoir 29 gesammelt. Der Antrieb der Schleuderscheibe 1 erfolgt mittels Motor 14 über Antriebsachse 12. Aus dem Reservoir 29 wird der Volumenstrom V3 mittels Pumpenscheibe 30 gefördert und mit dem zugeführten Volumenstrom V1 vereinigt, und gemeinsam wiederum dem Schleuderrad 1 aufgegeben. Statt des Fließweges 26, 28 ist auch die alternative, in unterbrochener Linie dargestellte, Leitungsführung L3 möglich, die jedoch, wie beschrieben, ein anderes Verhalten der Vorrichtung bedingt.Figure 4 shows schematically the operation of the Contraption. A container B is turned into a dosing pump P1 a volume flow V1 is sucked in from line L1 and the Centrifugal disc 1 supplied. From there becomes a sub-volume V4 the droplets formed are thrown off. The rest will be in Housing 3 retained and collected in the reservoir 29. The The centrifugal disc 1 is driven by a motor 14 via drive axle 12. The reservoir 29 becomes the Volume flow V3 promoted by means of pump disc 30 and with the supplied volume flow V1 combined, and together again abandoned the centrifugal wheel 1. Instead of Flow path 26, 28 is also the alternative, in broken line, line L3 possible, however, as described, a different behavior due to the device.
