Description

Gebiet der Erfindungfield of invention

Die Erfindung betrifft ein Saugfahrzeug mit einem Sauggebläse, einer Saugleitung und einem Saugmund zur Führung eines Saugstromes. Der Saugmund umfasst eine Basiseinheit und eine an der Basiseinheit angeordnete Adaptereinheit. Die Adaptereinheit umfasst eine Saugöffnung und eine Adapterauslassöffnung.

The suction mouth comprises a base unit and an adapter unit arranged on the base unit. The adapter unit includes a suction port and an adapter outlet port. The vacuum vehicle is designed in such a way that the suction stream flows through the suction opening into the adapter unit, from the adapter unit through the adapter outlet opening into the base unit and through the suction line.

Hintergrundbackground

Kommunale Behörden pflegen ihre Infrastruktur insbesondere mittels sogenannten Mehrzweck-Fahrzeugen. An solchen Mehrzweck-Fahrzeugen können beispielsweise eine Kehrvorrichtung mit Kehrbesen zur Beseitigung von Splitt, Schutt und anderen Materialien, eine Schrubbvorrichtung zur gründlichen Reinigung von Oberflächen oder ein Mähwerk zur Pflege von Rasen montiert werden. Beim Kehren, Schrubben und Mähen saugt eine Saugvorrichtung den Schmutz oder andere Materialien in einen Sammelbehälter ein.Municipal authorities maintain their infrastructure in particular by means of so-called multi-purpose vehicles. Such multi-purpose vehicles can, for example, be fitted with a sweeper with broom for removing chippings, debris and other materials, a scrubber for thorough cleaning of surfaces or a mower for lawn care. When sweeping, scrubbing, and mowing, a suction device sucks the dirt or other materials into a collection container.

Solche Mehrzweck-Fahrzeuge können beispielsweise aber auch mit einer Schwemmanlage, mit einem Giessarm, mit einem Salzstreugerät oder mit einer Schneeräumvorrichtung ausgerüstet werden. Bei solchen Anwendungen ist die Saugvorrichtung ausser Betrieb.However, such multi-purpose vehicles can also be equipped, for example, with a flooding system, with a watering arm, with a salt spreader or with a snow-clearing device. In such applications, the suction device is out of order.

Der Vorteil solcher Mehrzweck-Fahrzeuge besteht darin, dass eine Kommune beispielsweise nur ein einziges Fahrzeug benötigt, weil an diesem verschiedenste Vorrichtungen für die erwähnten Anwendungen modular montiert werden können.The advantage of such multi-purpose vehicles is that a municipality only needs a single vehicle, for example, because a wide variety of devices for the applications mentioned can be mounted on it in a modular manner.

Mehrzweck-Fahrzeuge sind bevorzugt derart auszugestalten, dass sich die verschiedenen Module mit möglichst wenig Aufwand montieren und wieder demontieren lassen.Multi-purpose vehicles should preferably be designed in such a way that the various modules can be assembled and disassembled again with as little effort as possible.

EP 2 447 419 und EP 2 778 288 zeigen eine Bodenreinigungsmaschine mit einem koppelbaren Anbauteil. Das Anbauteil umfasst eine Saugöffnung. EP 2 447 419 and EP 2 778 288 show a floor cleaning machine with an attachable attachment. The attachment includes a suction opening.

FR 2 949 795 offenbart eine Saugleitung für ein Reinigungsfahrzeug. Die Saugleitung hat ein offenes Ende vor der Vorderachse des Fahrzeuges. Das offene Ende kann durch einen Stutzen verlängert werden. FR 2 949 795 discloses a suction line for a cleaning vehicle. The suction line has an open end in front of the front axle of the vehicle. The open end can be extended with a stub.

EP 2 168 424 zeigt eine Vorbau-Aufnahmeeinheit für ein Laubsammelfahrzeug. Die Aufnahmeeinheit ist mittels zweier aussenseitig angeordneten Tragarmen am Vorderachsteil befestigt. EP 2 168 424 shows a front-mounted receiving unit for a leaf collection vehicle. The receiving unit is attached to the front axle part by means of two support arms arranged on the outside.

US 9 702 101 beschreibt ein Bedieneinheit mit austauschbaren Aufsätzen für einen Industrie-Sauger, der beispielsweise bei Erdgrabungen zum Einsatz kommen kann. U.S. 9,702,101 describes a control unit with interchangeable attachments for an industrial vacuum cleaner, which can be used, for example, in excavations.

Darstellung der ErfindungPresentation of the invention

Es stellt sich die Aufgabe, ein Saugfahrzeug bereitzustellen, bei welchem der Saugmund möglichst einfach an verschiedenste Anwendungen angepasst werden kann.The task is to provide a suction vehicle in which the suction mouth can be adapted as simply as possible to a wide variety of applications.

Diese Aufgabe wird durch den Gegenstand des unabhängigen Anspruchs gelöst.This object is solved by the subject matter of the independent claim.

Demgemäss umfasst ein Saugfahrzeug, ein Sauggebläse, eine Saugleitung und einen Saugmund zur Führung eines Saugstromes. Der Saugmund weist eine Basiseinheit und eine an der Basiseinheit angeordnete Adaptereinheit auf. Die Adaptereinheit ist vom Saugfahrzeug und von der Basiseinheit entkoppelbar.Accordingly, a suction vehicle comprises a suction fan, a suction line and a suction mouth for guiding a suction flow. The suction mouth has a base unit and an adapter unit arranged on the base unit. The adapter unit can be decoupled from the suction vehicle and from the base unit.

Die Adaptereinheit umfasst eine Saugöffnung und eine Adapterauslassöffnung. Im Betrieb strömt der Saugstrom durch die Saugöffnung in die Adaptereinheit ein. Der Saugstrom strömt durch die Adaptereinheit und verlässt diese durch die Adapterauslassöffnung. Von dort strömt der Saugstrom in die Basiseinheit und durch die Saugleitung.The adapter unit includes a suction port and an adapter outlet port. During operation, the suction flow flows through the suction opening into the adapter unit. The suction stream flows through the adapter unit and leaves it through the adapter outlet opening. From there, the suction stream flows into the base unit and through the suction line.

Weil lediglich die Adaptereinheit für unterschiedliche Sauganwendungen ausgewechselt werden muss, gestaltet sich die Anpassung des Saugfahrzeugs an unterschiedliche Sauganwendungen besonders einfach. Die Saugvorrichtung, das Sauggebläse, die Saugleitung und die Basiseinheit sind am Saugfahrzeug insbesondere fix montiert.Because only the adapter unit has to be exchanged for different suction applications, it is particularly easy to adapt the suction vehicle to different suction applications. The suction device, the suction fan, the suction line and the base unit are in particular permanently mounted on the suction vehicle.

Die Adaptereinheit ist zur Kopplung mit dem Saugfahrzeug seitwärts zur Hauptfahrtrichtung auf die Basiseinheit schiebbar.The adapter unit can be slid sideways to the main direction of travel onto the base unit for coupling to the suction vehicle.

Seitwärts bedeutet insbesondere in einem Winkel zwischen 45° bis 135° zur Hauptfahrtrichtung.Sideways means in particular at an angle of between 45° and 135° to the main direction of travel.

Insbesondere bei einem Saugfahrzeug ist die Hauptfahrtrichtung gerade nach vorne bei neutraler Lenkstellung.In the case of a suction vehicle in particular, the main direction of travel is straight ahead with the steering position in neutral.

Die Adapterauslassöffnung ist seitlich, insbesondere an einer Rückseite, der Adaptereinheit angeordnet. Dies bedeutet, dass bei normaler Betriebsposition der Saugstrom die Adaptereinheit weder gegen oben, noch gegen unten verlässt. Der Saugstrom tritt seitlich aus der Adaptereinheit aus. Die Ankopplung an die Basiseinheit kann dadurch besonders einfach ausgestaltet werden. Der Begriff "seitlich" schliesst oben und unten aus, beinhaltet aber alle anderen Seiten der Adaptereinheit. Ist die Adaptereinheit beispielsweise quaderförmig ausgestaltet, so würde der Begriff "seitlich" die Vorderseite, die Rückseite, die linke und die rechte Seite umfassen.The adapter outlet opening is arranged on the side, in particular on a rear side, of the adapter unit. This means that in the normal operating position, the suction flow leaves the adapter unit neither up nor down. The suction flow emerges from the side of the adapter unit. As a result, the coupling to the base unit can be configured in a particularly simple manner. The term "side" excludes top and bottom but includes all other sides of the adapter assembly. If the adapter unit is cuboid, for example, the term "sideways" would include the front, the back, the left and the right side.

Vorteilhaft ist die Adaptereinheit, insbesondere im Wesentlichen, gegen hinten offen ausgestaltet. Dies bedeutet, dass die Adaptereinheit im Wesentlichen keine rückseitige Wandung umfasst. Der Saugstrom wird in der Adaptereinheit somit insbesondere von Seitenwänden und durch eine obere und eine untere Begrenzung geführt und verlässt die Adaptereinheit gegen hinten. Insbesondere erfolgt die Begrenzung gegen oben durch eine Abdeckung und gegen unten durch die zu saugende Oberfläche, beispielsweise durch die Strassenoberfläche. "Hinten" ist in Bezug auf die Fahrtrichtung zu verstehen, d.h. der Saugstrom tritt vorne ein und tritt gegen hinten wieder aus.The adapter unit is advantageously designed to be open towards the rear, in particular essentially. This means that the adapter unit essentially no back wall included. The suction flow is thus guided in the adapter unit in particular by side walls and through an upper and a lower limit and leaves the adapter unit towards the rear. In particular, the upper limit is provided by a cover and the lower limit is provided by the surface to be vacuumed, for example the road surface. "Rear" is to be understood in relation to the direction of travel, ie the suction flow enters at the front and exits towards the rear.

In einer besonderen Ausführungsform ist der Saugmund derart ausgestaltet, dass der Saugstrom im Wesentlichen horizontal von der Adaptereinheit in die Basiseinheit strömt. Der Saugstrom verlässt die Adaptereinheit somit nicht mit einer teilweise nach oben gerichteten Strömungsrichtung.In a special embodiment, the suction mouth is designed in such a way that the suction stream flows essentially horizontally from the adapter unit into the base unit. The suction flow thus does not leave the adapter unit with a partial upward flow direction.

Insbesondere ist die Saugöffnung maximal 1.1-mal, insbesondere maximal 1.2-mal, insbesondere maximal 1.5-mal, insbesondere maximal 2-mal so breit wie die Adapterauslassöffnung. Mit anderen Worten verengt sich die Strömungsfläche des Saugstromes innerhalb der Adaptereinheit gar nicht oder nur geringfügig. Es ist auch möglich, dass sich die Strömungsfläche des Saugstromes innerhalb der Adaptereinheit vergrössert. Dadurch kann die Adaptereinheit in seiner Länge entlang der Strömungsrichtung relativ kurz gehalten werden, da die Verengung der Strömungsfläche in der Hauptsache innerhalb der Basiseinheit und nicht innerhalb der Adaptereinheit erfolgt.In particular, the suction opening is at most 1.1 times, in particular at most 1.2 times, in particular at most 1.5 times, in particular at most 2 times as wide as the adapter outlet opening. In other words, the flow area of the suction flow does not narrow at all or only slightly within the adapter unit. It is also possible that the flow area of the suction flow increases within the adapter unit. As a result, the length of the adapter unit along the flow direction can be kept relatively short, since the narrowing of the flow surface occurs mainly within the base unit and not within the adapter unit.

Insbesondere ist die Adaptereinheit, insbesondere die Adapterauslassöffnung, gegen unten offen ausgestaltet. D.h. die Adaptereinheit wird maximal nur gegen oben und seitlich durch Wandungen begrenzt. Im Betrieb wird insbesondere der Saugstrom von unten durch die zu saugende Oberfläche geführt. Die Adaptereinheit kann dadurch äusserst einfach ausgestaltet werden.In particular, the adapter unit, in particular the adapter outlet opening, is designed to be open towards the bottom. This means that the adapter unit is limited at most only towards the top and sides by walls. During operation, the suction stream in particular is guided from below through the surface to be vacuumed. As a result, the adapter unit can be designed in an extremely simple manner.

Mit Vorteil ist die Adaptereinheit im Wesentlichen quaderförmig ausgestaltet und weist eine offene Rückseite und eine offene Unterseite auf.Advantageously, the adapter unit is essentially cuboid and has an open rear and an open underside.

In einer besonderen Ausführungsform verengt sich die Strömungsfläche innerhalb der Basiseinheit mindestens um das 1.2-fache, insbesondere mindestens um das 1.5-fache, insbesondere mindestens um das 2-fache, insbesondere mindestens um das 3-fache. Eine Verengung der Strömungsfläche bedeutet, dass die Querschnittsfläche an der Basiseinheitauslassöffnung kleiner ist als an der Basiseinheiteinlassöffnung. Die Strömungsfläche verkleinert sich innerhalb der Basiseinheit entlang der Strömungsrichtung.In a particular embodiment, the flow area within the base unit narrows by at least 1.2 times, in particular at least 1.5 times, in particular at least 2 times, in particular at least 3 times. A narrowing of the flow area means that the cross-sectional area at the base unit outlet port is smaller than at the base unit inlet port. The flow area decreases within the base unit along the direction of flow.

Insbesondere ist die Basiseinheit vom Saugfahrzeug nicht entkoppelbar.In particular, the base unit cannot be decoupled from the suction vehicle.

Die Verengung der Strömungsfläche innerhalb der Basiseinheit hat den Vorteil, dass die Strömungsfläche nicht innerhalb der Adaptereinheit verengt werden muss, sodass die Adaptereinheit möglichst kompakt ausgestaltet werden kann.The narrowing of the flow area within the base unit has the advantage that the flow area does not have to be narrowed within the adapter unit, so that the adapter unit can be configured as compactly as possible.

Mit Vorteil ist an der Oberseite der Adaptereinheit eine Kopplungsschiene zur Kopplung der Adaptereinheit mit dem Saugfahrzeug angeordnet. Dies erlaubt ein einfaches Koppeln und Entkoppeln der Adaptereinheit mit dem Saugfahrzeug.A coupling rail for coupling the adapter unit to the suction vehicle is advantageously arranged on the upper side of the adapter unit. This allows easy coupling and decoupling of the adapter unit with the suction vehicle.

Vorteilhaft ist die Erstreckung der Adaptereinheit quer zur Strömungsrichtung des Saugstromes grösser, insbesondere mindestens 1.5 mal so gross, insbesondere mindestens doppelt so gross, insbesondere mindestens dreimal so gross, als die Erstreckung der Adaptereinheit in Strömungsrichtung. Die Adaptereinheit ist damit äusserst kompakt ausgestaltet, sodass die Kopplung und Entkopplung mit dem Saugfahrzeug äusserst einfach durchgeführt werden kann.Advantageously, the extension of the adapter unit transversely to the flow direction of the suction flow is greater, in particular at least 1.5 times as large, in particular at least twice as large, in particular at least three times as large, than the extension of the adapter unit in the flow direction. The adapter unit is thus designed to be extremely compact, so that the coupling and decoupling with the suction vehicle can be carried out extremely easily.

Insbesondere ist die Basiseinheit, insbesondere mit der Adaptereinheit, anhebbar und absenkbar innerhalb des Saugfahrzeugs angeordnet. Dadurch kann die Basiseinheit innerhalb des Saugfahrzeugs verstaut werden, sodass weitere Vorrichtungen, beispielsweise ein Schneepflug, am Saugfahrzeug montiert werden können, welche die Saugvorrichtung nicht benötigen.In particular, the base unit, in particular with the adapter unit, is arranged such that it can be raised and lowered inside the suction vehicle. This allows the Base unit can be stowed inside the suction vehicle, so that other devices, such as a snow plow, can be mounted on the suction vehicle, which do not require the suction device.

In einer besonderen Ausführungsform umfasst die Adaptereinheit Vorsprünge und das Saugfahrzeug Greifelemente, welche derart ausgestaltet sind, dass die Adaptereinheit koppelbar ist, indem das Saugfahrzeug die Adaptereinheit überfährt und mit den Greifelementen die Vorsprünge umgreift.In a particular embodiment, the adapter unit includes projections and the suction vehicle gripping elements, which are designed such that the adapter unit can be coupled by the suction vehicle running over the adapter unit and gripping the projections with the gripping elements.

Mit Vorteil ist die Adaptereinheit eine Kehrvorrichtung, eine Schrubbvorrichtung, oder eine Mähvorrichtung und/oder das Saugfahrzeug umfasst einen Führersitz, insbesondere wobei der Saugmund unterhalb des Führersitzes angeordnet ist, und/oder das Saugfahrzeug umfasst einen Fahrantrieb.The adapter unit is advantageously a sweeping device, a scrubbing device, or a mowing device and/or the suction vehicle includes a driver's seat, in particular with the suction nozzle being arranged below the driver's seat, and/or the suction vehicle includes a traction drive.

Wege zur Ausführung der ErfindungWays to carry out the invention

Fig. 1 zeigt ein Saugfahrzeug mit einem Vorderwagen 1 und einem Hinterwagen 2. Der Vorderwagen 1 umfasst eine Führerkabine 3 mit einem Führersitz 4 und eine Vorderradeinrichtung 5. Der Hinterwagen 2 umfasst eine Hinterradeinrichtung 6 und einen Aufnahmebereich 7 für einen Aufbau, welcher auswechselbar ist. Beim Aufbau handelt es sich vorliegend um einen Saugbehälter 8 mit einem Sauggebläse 9. Als Aufbau könnte beispielsweise auch ein Tank, ein Streuer usw. vorgesehen sein. 1 shows a suction vehicle with a front end 1 and a rear end 2. The front end 1 includes a driver's cab 3 with a driver's seat 4 and a front wheel device 5. The rear end 2 includes a rear wheel device 6 and a receiving area 7 for a structure that is interchangeable. In the present case, the structure is a suction container 8 with a suction fan 9. A tank, a spreader, etc., for example, could also be provided as a structure.

Im Weiteren ist am Hinterwagen 2 ein Fahrantrieb 10 angeordnet. Die Hauptfahrtrichtung des Saugfahrzeuges entspricht dem Pfeil 11. Entsprechend der Hauptfahrtrichtung sind auch das vordere Ende 12 und das hintere Ende 13 des Saugfahrzeuges definiert.Furthermore, a travel drive 10 is arranged on the rear carriage 2 . The main direction of travel of the suction vehicle corresponds to the arrow 11. The front end 12 and the rear end 13 of the suction vehicle are also defined in accordance with the main direction of travel.

Alternativ kann das Saugfahrzeug ohne Knicklenkung ausgestaltet sein. Es kann insbesondere ein vierradgelenktes oder ein zweiradgelenktes Fahrzeug sein. Der Vorderwagen umfasst ein Fahrgestell 14, an welchem die Vorderradeinrichtung 5, eine Kehrvorrichtung 15 und ein Saugmund 16 angeordnet sind. Der Saugmund 16 und der Saugbehälter 8 sind über eine Saugleitung 17 miteinander verbunden. Der Saugstrom strömt somit durch den Saugmund 16 und durch die Saugleitung 17 bis zum Saugbehälter 8.Alternatively, the suction vehicle can be designed without articulated steering. In particular, it can be a four-wheel-steered vehicle or a two-wheel-steered vehicle. The front end comprises a chassis 14 on which the front wheel device 5, a sweeping device 15 and a suction mouth 16 are arranged. The suction mouth 16 and the suction container 8 are connected to one another via a suction line 17 . The suction flow thus flows through the suction mouth 16 and through the suction line 17 to the suction container 8.

Die Kehrvorrichtung 15 umfasst mindestens zwei Besen 18, welche zueinander beabstandet und am vorderen Ende 12 des Fahrzeuges angeordnet sind. Sie bewegen sich in Drehrichtung 19, wie es in Fig. 2 eingezeichnet ist. Die beiden Besen 18 reinigen die zu reinigende Oberfläche 20, welche insbesondere eine Strasse ist, und befördern Splitt, Schutt und anderen Materialien, welche sich auf der Strasse befinden, zur Mitte zwischen die beiden Besen 18, und gegen hinten in Pfeilrichtung 21 zum Saugmund 16.The sweeping device 15 comprises at least two brooms 18 which are spaced apart and arranged at the front end 12 of the vehicle. They move in the direction of rotation 19, as shown in 2 is drawn. The two brooms 18 clean the surface to be cleaned 20, which is in particular a road, and transport chippings, rubble and other materials that are on the road to the center between the two brooms 18 and towards the rear in the direction of arrow 21 to the suction mouth 16.

Der Saugmund 16 ist unterhalb des Fahrgestells 14, unterhalb des Führersitzes 4 und zwischen den Rädern der Vorderradeinrichtung 5 angeordnet. Er umfasst eine Adaptereinheit 22 und eine Basiseinheit 23. Die Basiseinheit 23 ist mit dem Saugfahrzeug fest verbunden. Innerhalb des Saugfahrzeuges kann sie angehoben und damit bei Nichtgebrauch der Saugfunktion versorgt werden. Bei den Fig. 1 befindet sich die Basiseinheit 23 in Betrieb. Sie stützt sich über Räder auf der zu reinigenden Oberfläche 20 ab.The suction mouth 16 is arranged below the chassis 14, below the driver's seat 4 and between the wheels of the front wheel device 5. It includes an adapter unit 22 and a base unit 23. The base unit 23 is firmly connected to the suction vehicle. Inside the suction vehicle, it can be raised and thus supplied when the suction function is not in use. Both 1 the base unit 23 is in operation. It is supported on wheels on the surface 20 to be cleaned.

Die Fig. 2 zeigt die Adaptereinheit 22 in einem nicht montierten Zustand. Die Adaptereinheit 22 kann, seitwärts (wie in Fig. 2 illustriert) auf die Basiseinheit 23 aufgeschoben werden. Die Seitwärtsrichtung steht in der vorliegenden Ausführungsform rechtwinklig zur Hauptfahrtrichtung 11. Im Sinne der Erfindungsdefinition bedeutet seitwärts aber nicht ausschliesslich im rechten Winkel. Seitwärts bedeutet insbesondere in einem Winkel zwischen 45° bis 135° zur Hauptfahrtrichtung 11.The 2 shows the adapter unit 22 in an unassembled state. The adapter unit 22 can, sideways (as in 2 illustrated) are pushed onto the base unit 23. In the present embodiment, the sideways direction is at right angles to the main direction of travel 11. However, within the meaning of the definition of the invention, sideways does not mean exclusively at right angles. Sideways means in particular at an angle of between 45° and 135° to the main direction of travel 11.

In den Fig. 3, 4 und 5 wird der Saugmund mit der Basiseinheit 23 und der Adaptereinheit 22 detailliert dargestellt. Die Fig. 3 und 5 zeigen den Saugmund in entkoppelter Form. In Fig. 4 ist der Saugmund in gekoppelter, betriebsbereiter Position gezeigt.In the Figures 3, 4 and 5 the suction mouth with the base unit 23 and the adapter unit 22 is shown in detail. The 3 and 5 show the suction mouth in a decoupled form. In 4 the suction mouth is shown in the coupled, operative position.

Das Saugfahrzeug bewegt sich in Hauptfahrtrichtung 11. Der Schmutz gelangt von der zu reinigenden Oberfläche durch eine Saugöffnung 24 in Richtung 25 in die Adaptereinheit 22. In der Adaptereinheit wird der Schmutz vom Saugstrom erfasst. An der Vorderseite der Adaptereinheit 22 ist eine Abdeckung 26 angeordnet, welche so gross ausgestaltet ist, dass der Schmutz durch die Saugöffnung 24 in die Adaptereinheit 22 gelangt, gleichzeitig aber so klein ausgestaltet ist, dass der Saugstrom immer noch eine genügende Saugkraft aufweist.The suction vehicle moves in the main direction of travel 11. The dirt passes from the surface to be cleaned through a suction opening 24 in direction 25 into the adapter unit 22. In the adapter unit, the dirt is picked up by the suction flow. At the front of the adapter unit 22, a cover 26 is arranged, which is designed so large that the dirt through the Suction opening 24 reaches the adapter unit 22, but at the same time is designed so small that the suction flow still has sufficient suction power.

An der Rückseite der Adaptereinheit 22 verlässt der Saugstrom die Adaptereinheit 22 durch die an der Rückseite angeordnete Adapterauslassöffnung 27 in Pfeilrichtung 28. Der Saugstrom führt den aufgenommenen Schmutz mit sich. Die Adaptereinheit 22 ist im wesentlichen quaderförmig und gegen unten offen ausgestaltet.At the rear of the adapter unit 22, the suction flow leaves the adapter unit 22 through the adapter outlet opening 27 arranged on the rear in the direction of the arrow 28. The suction flow carries the picked-up dirt with it. The adapter unit 22 is designed essentially cuboid and open towards the bottom.

Sodann strömt der Saugstrom in Pfeilrichtung 29 von der Adapterauslassöffnung 27 in die Basiseinheit 23. Die Pfeilrichtungen 28 und 29 sind identisch, werden in der Fig. 3 aber separat dargestellt, weil die Adaptereinheit 22 und die Basiseinheit 23 versetzt und entkoppelt dargestellt sind.Then the suction stream flows in the direction of the arrow 29 from the adapter outlet opening 27 into the base unit 23. The directions of the arrows 28 and 29 are identical 3 but shown separately because adapter unit 22 and base unit 23 are shown offset and decoupled.

Innerhalb der Basiseinheit 23 verengt sich der Saugstrom im Trichter 30 auf die Strömungsfläche der Saugleitung 17 und strömt durch diese zum Saugbehälter 8.Within the base unit 23, the suction flow narrows in the funnel 30 onto the flow surface of the suction line 17 and flows through it to the suction container 8.

Die Verengung des Saugstromes auf die Strömungsfläche der Saugleitung 17 findet somit hauptsächlich innerhalb der Basiseinheit 23 statt. Innerhalb der Adaptereinheit 22 hingegen verengt sich die Strömung gar nicht. In einer alternativen Ausführungsform könnte sich die Strömung nur wenig verengen. Die Saugöffnung 24 und die Adapterauslassöffnung 27 weisen identische Breiten 31 und 32 auf. Dadurch kann die Adaptereinheit 22 in der Länge 33 kurz und damit insgesamt äusserst kompakt ausgestaltet werden.The constriction of the suction flow onto the flow surface of the suction line 17 thus takes place mainly within the base unit 23 . In contrast, the flow does not narrow at all within the adapter unit 22 . In an alternative embodiment, the flow could narrow only slightly. The suction opening 24 and the adapter outlet opening 27 have identical widths 31 and 32. As a result, the adapter unit 22 can be designed to be short in length 33 and therefore extremely compact overall.

Wie bereits erwähnt sind in der Fig. 3 die Adaptereinheit 22 und die Basiseinheit 23 seitlich versetzt und entkoppelt dargestellt. Um den Saugmund betriebsbereit zu erstellen, muss die Adaptereinheit 22 seitwärts entlang der gestrichelten Linie 34 auf die Basiseinheit 23 geschoben werden. Hierfür umfasst die Adaptereinheit 22 eine Kopplungsschiene 35, welche in eine Führung 36 der Basiseinheit 23 seitwärts eingeschoben werden kann.As already mentioned in the 3 the adapter unit 22 and the base unit 23 are shown laterally offset and decoupled. In order to prepare the suction mouth for operation, the adapter unit 22 must be pushed sideways along the dotted line 34 onto the base unit 23. For this purpose, the adapter unit 22 includes a coupling rail 35 which can be pushed sideways into a guide 36 of the base unit 23 .

Die Fig. 4 zeigt den Saugmund in einem gekoppelten und betriebsbereiten Zustand. Eine Arretiervorrichtung 37 fixiert die Kopplungsschiene 35 der Adaptereinheit 22 mit der Führung 36 der Basiseinheit 23. über das Verbindungselement 38 kann die Abdeckung 26 bewegt werden, um die Saugöffnung 24 zu vergrössern und zu verkleinern. Dadurch können verschieden grosse Gegenstände eingesogen werden.The 4 shows the suction mouth in a coupled and operational state. A locking device 37 fixes the coupling rail 35 of the adapter unit 22 to the guide 36 of the base unit 23. The cover 26 can be moved via the connecting element 38 in order to enlarge and reduce the suction opening 24. This allows objects of different sizes to be sucked in.

Der Saugstrom strömt von der Adaptereinheit 22 im Wesentlichen horizontal in die Basiseinheit 23 und dann durch den Trichter 30 in die Saugleitung 17.The suction stream flows from the adapter unit 22 essentially horizontally into the base unit 23 and then through the funnel 30 into the suction line 17.

Die Fig. 5 zeigt den Saugmund in entkoppeltem Zustand von der Rückseite. An der Rückseite der Adaptereinheit 22 ist die Auslassöffnung 27 sichtbar. Vorliegend wird die Adapterauslassöffnung 27 dadurch gebildet, dass die Rückseite der Adaptereinheit 22 offen ausgestaltet ist. Die Adaptereinheit 22 wird somit lediglich von einer Abdeckung 26 zur Vorderseite, von seitlichen Wandungen und von einer oberen Wandung begrenzt.The figure 5 shows the suction mouth in a decoupled state from the back. The outlet opening 27 can be seen on the back of the adapter unit 22 . In the present case, the adapter outlet opening 27 is formed in that the rear side of the adapter unit 22 is designed to be open. The adapter unit 22 is thus limited only by a cover 26 to the front, by side walls and by a top wall.

Der Saugstrom strömt sodann innerhalb der Basiseinheit 23 durch den Trichter 30 in die Saugleitung 17. Zur Rückseite hin wird der Strömungskanal durch eine rückseitige Abdeckung 39 der Basiseinheit 23 begrenzt.The suction stream then flows inside the base unit 23 through the funnel 30 into the suction line 17. The flow channel is delimited towards the rear by a rear cover 39 of the base unit 23.

Die Fig. 6 zeigt eine Schnittansicht durch die Mitte des gekoppelten Saugmundes, d.h. einen Schnitt durch den Saugmund gemäss Fig. 4. Die Kopplungsschiene 35 und die Führung 36 liegen ineinander, sodass die Adaptereinheit 22 und die Basiseinheit 23 miteinander gekoppelt sind.The 6 shows a sectional view through the middle of the coupled suction mouth, ie a section through the suction mouth according to FIG 4 . The coupling rail 35 and the guide 36 lie one inside the other, so that the adapter unit 22 and the base unit 23 are coupled to one another.

Die Fig. 7 zeigt eine alternative Adaptereinheit, welche Vorsprünge 43 umfasst. Die Adaptereinheit 22 kann mit der Basiseinheit gekoppelt werden, indem das Saugfahrzeug die Adaptereinheit 22 überfährt, mittels Greifelementen 44, welche am Saugfahrzeug angeordnet sind, umgreift, und damit die Adaptereinheit an die Basiseinheit koppelt.The 7 Figure 12 shows an alternative adapter unit comprising projections 43. The adapter unit 22 can be coupled to the base unit by the suction vehicle driving over the adapter unit 22, gripping it by means of gripping elements 44 which are arranged on the suction vehicle, and thus coupling the adapter unit to the base unit.

Die Fig. 8 zeigt ein Saugfahrzeug mit einer Schrubbvorrichtung 40 und die Fig. 9 zeigt ein Saugfahrzeug mit einer Mähvorrichtung 41. Auch bei diesen beiden Saugfahrzeugen kann die Basiseinheit 23 innerhalb des Fahrzeuges angehoben und abgesenkt werden.The 8 shows a vacuum vehicle with a scrubbing device 40 and the 9 1 shows a suction vehicle with a mowing device 41. With these two suction vehicles, too, the base unit 23 can be raised and lowered inside the vehicle.

Während in der vorliegenden Anmeldung bevorzugte Ausführungen der Erfindung beschrieben sind, ist klar darauf hinzuweisen, dass die Erfindung nicht auf diese beschränkt ist und in auch anderer Weise innerhalb des Umfangs der folgenden Ansprüche ausgeführt werden kann.While the present application describes preferred embodiments of the invention, it is to be understood that the invention is not limited thereto and may be otherwise embodied within the scope of the following claims.
