Description

Gebiet der ErfindungField of invention

Die Erfindung betrifft eine Saugmaschine, insbesondere 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. Die Saugmaschine ist derart ausgestaltet, dass der Saugstrom durch die Saugöffnung in die Adaptereinheit, von der Adaptereinheit durch die Adapterauslassöffnung in die Basiseinheit und durch die Saugleitung strömt.The invention relates to a suction machine, in particular a suction vehicle, with a suction fan, a suction line and a suction mouth for guiding a suction flow. The suction mouth comprises a base unit and an adapter unit arranged on the base unit. The adapter unit comprises a suction opening and an adapter outlet opening. The suction machine is designed in such a way that the suction flow 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.Local authorities maintain their infrastructure in particular using so-called multi-purpose vehicles. For example, a sweeping device with a broom to remove grit, debris and other materials, a scrubbing device for thorough cleaning of surfaces or a mower for maintaining lawns can be mounted on such multi-purpose vehicles. 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.Such multi-purpose vehicles can, for example, also be equipped with a washer system, a pouring arm, a salt spreader or a snow clearing device. In such applications, the suction device is out of operation.

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 modularly mounted on it.

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

Darstellung der ErfindungPresentation of the invention

Es stellt sich die Aufgabe, eine Saugmaschine bereitzustellen, bei welcher der Saugmund möglichst einfach an verschiedenste Anwendungen angepasst werden kann.The object is to provide a suction machine in which the suction mouth can be adapted as easily as possible to a wide variety of applications.

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

Demgemäss umfasst eine Saugmaschine, insbesondere 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 von der Saugmaschine und von der Basiseinheit entkoppelbar.Accordingly, a suction machine, in particular 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 one on the base unit arranged adapter unit. The adapter unit can be decoupled from the suction machine 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 comprises a suction opening and an adapter outlet opening. During operation, the suction stream flows into the adapter unit through the suction opening. 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 der Saugmaschine an unterschiedliche Sauganwendungen besonders einfach. Die Saugvorrichtung, das Sauggebläse, die Saugleitung und die Basiseinheit sind an der Saugmaschine insbesondere fix montiert.Because only the adapter unit has to be exchanged for different suction applications, adapting the suction machine to different suction applications is particularly easy. The suction device, the suction fan, the suction line and the base unit are in particular fixedly mounted on the suction machine.

Mit Vorteil ist die Adaptereinheit zur Kopplung mit der Saugmaschine seitwärts zur Hauptfahrtrichtung auf die Basiseinheit schiebbar.The adapter unit for coupling with the suction machine can advantageously be slid sideways to the main direction of travel onto the base unit.

Seitwärts bedeutet insbesondere in einem Winkel zwischen 45° bis 135° zur Hauptfahrtrichtung.Sideways means in particular at an angle 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 a neutral steering position.

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 laterally, in particular on a rear side, of the adapter unit. This means that in the normal operating position the suction flow does not leave the adapter unit either upwards or downwards. The suction flow emerges from the side of the adapter unit. The coupling to the base unit can thereby be configured in a particularly simple manner. The term "side" excludes top and bottom, but includes all other sides of the adapter unit. If the adapter unit is designed, for example, in the shape of a cuboid, the term "side" would include the front, the rear, 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, in particular essentially, to be open towards the rear. This means that the adapter unit essentially does not include a rear wall. In the adapter unit, the suction flow is thus guided in particular by side walls and through an upper and a lower limit and leaves the adapter unit towards the rear. In particular, the top is limited by a cover and the bottom by the surface to be vacuumed, for example by the road surface. "Rear" is to be understood in relation to the direction of travel, i.e. the suction flow enters the front and exits again 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 particular embodiment, the suction mouth is designed such that the suction stream flows essentially horizontally from the adapter unit into the base unit. The suction flow therefore does not leave the adapter unit with a partially 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 a maximum of 1.1 times, in particular a maximum of 1.2 times, in particular a maximum of 1.5 times, in particular a maximum of 2 times as wide as the adapter outlet opening. In other words, the flow area of the suction flow within the adapter unit does not narrow at all or only slightly. It is also possible for the flow area of the suction flow inside the adapter unit to increase. As a result, the length of the adapter unit can be kept relatively short along the direction of flow, since the narrowing of the flow area takes place 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. In other words, the adapter unit is only limited by walls at the top and at the sides. In particular, the suction flow from below through the to absorbent surface. The adapter unit can thus be configured extremely simply.

Mit Vorteil ist die Adaptereinheit im Wesentlichen quaderförmig ausgestaltet und weist eine offene Rückseite und eine offene Unterseite auf.The adapter unit is advantageously designed essentially in the shape of a cuboid and has an open rear side 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 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 opening is smaller than at the base unit inlet opening. The flow area decreases within the base unit along the flow direction.

Insbesondere ist die Basiseinheit von der Saugmaschine nicht entkoppelbar.In particular, the base unit cannot be decoupled from the suction machine.

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 made as compact as possible.

Mit Vorteil ist an der Oberseite der Adaptereinheit eine Kopplungsschiene zur Kopplung der Adaptereinheit mit der Saugmaschine angeordnet. Dies erlaubt ein einfaches Koppeln und Entkoppeln der Adaptereinheit mit der Saugmaschine.A coupling rail for coupling the adapter unit to the suction machine is advantageously arranged on the top of the adapter unit. This allows the adapter unit to be easily coupled and uncoupled from the suction machine.

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 der Saugmaschine äusserst einfach durchgeführt werden kann.Advantageously, the extension of the adapter unit transversely to the direction of flow 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 as the extension of the adapter unit in the flow direction. The adapter unit is therefore designed to be extremely compact, so that the coupling and decoupling with the suction machine can be carried out extremely easily.

Insbesondere ist die Basiseinheit, insbesondere mit der Adaptereinheit, anhebbar und absenkbar innerhalb der Saugmaschine angeordnet. Dadurch kann die Basiseinheit innerhalb der Saugmaschine verstaut werden, sodass weitere Vorrichtungen, beispielsweise ein Schneepflug, an der Saugmaschine montiert werden können, welche die Saugvorrichtung nicht benötigen.In particular, the base unit, in particular with the adapter unit, can be raised and lowered within the suction machine. As a result, the base unit can be stowed inside the suction machine so that further devices, for example a snow plow, can be mounted on the suction machine which do not require the suction device.

In einer besonderen Ausführungsform umfasst die Adaptereinheit Vorsprünge und die Saugmaschine Greifelemente, welche derart ausgestaltet sind, dass die Adaptereinheit koppelbar ist, indem die Saugmaschine die Adaptereinheit überfährt und mit den Greifelementen die Vorsprünge umgreift.In a particular embodiment, the adapter unit comprises projections and the suction machine comprises gripping elements which are designed such that the adapter unit can be coupled in that the suction machine drives over the adapter unit and engages around the projections with the gripping elements.

Mit Vorteil ist die Adaptereinheit eine Kehrvorrichtung, eine Schrubbvorrichtung, oder eine Mähvorrichtung und/oder die Saugmaschine umfasst einen Führersitz, insbesondere wobei der Saugmund unterhalb des Führersitzes angeordnet ist, und/oder die Saugmaschine umfasst einen Fahrantrieb.The adapter unit is advantageously a sweeping device, a scrubbing device, or a mowing device and / or the suction machine comprises a driver's seat, in particular wherein the suction mouth is arranged below the driver's seat, and / or the suction machine comprises a drive.

Wege zur Ausführung der ErfindungWays of Carrying 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. Fig. 1 shows a suction vehicle with a front end 1 and a rear end 2. The front end 1 comprises a driver's cab 3 with a driver's seat 4 and a front wheel device 5. The rear end 2 comprises a rear wheel device 6 and a receiving area 7 for an interchangeable body. In the present case, the structure is a suction container 8 with a suction fan 9. For example, a tank, a spreader, etc. could also be provided as the 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. It can in particular be a four-wheel-steered or a two-wheel-steered vehicle. The front vehicle 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 stream 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 from one another and are arranged at the front end 12 of the vehicle. They move in the direction of rotation 19, as in Fig. 2 is drawn. The two brooms 18 clean the surface 20 to be cleaned, which is in particular a street, and transport grit, rubble and other materials that are on the street to the middle between the two brooms 18 and backwards 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 24 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 comprises an adapter unit 22 and a base unit 23. The base unit 23 is permanently connected to the suction vehicle. It can be lifted inside the suction vehicle and supplied with it when the suction function is not in use. Both Fig. 1 the base unit 23 is in operation. It is supported by wheels 24 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 24 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 Fig. 2 shows the adapter unit 22 in a non-assembled state. The adapter unit 22 can, sideways (as in Fig. 2 illustrated) can be pushed onto the base unit 23. In the present embodiment, the sideways direction 24 is at right angles to the main direction of travel 11. In the sense of the definition of the invention, sideways, but not exclusively, means at right angles. Sideways in particular means at an angle 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 Fig. 3, 4 and 5 the suction mouth with the base unit 23 and the adapter unit 22 is shown in detail. The Fig. 3 and 5 show the suction mouth in a decoupled form. In Fig. 4 the suction mouth is shown in a coupled, ready-to-use 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 the adapter unit 22. The dirt is captured by the suction flow in the adapter unit. On the front of the adapter unit 22 there is a cover 26 which is designed so large that the dirt gets through the suction opening 24 into the adapter unit 22, but at the same time is so small that the suction flow still has sufficient suction force.

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 dirt picked up 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.The suction stream then flows in the direction of the arrow 29 from the adapter outlet opening 27 into the base unit 23. The directions of arrows 28 and 29 are identical Fig. 3 but shown separately because the adapter unit 22 and the 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 in the funnel 30 narrows to the flow surface of the suction line 17 and flows through this 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 narrowing of the suction flow to the flow surface of the suction line 17 thus takes place mainly within the base unit 23. In contrast, within the adapter unit 22, the flow does not narrow at all. In an alternative embodiment, the flow could only narrow 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 made 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, the Fig. 3 the adapter unit 22 and the base unit 23 are shown laterally offset and decoupled. In order to make the suction mouth ready for operation, the adapter unit 22 can be pushed sideways along the dashed line 34 onto the base unit 23. For this purpose, the adapter unit 22 comprises 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 Fig. 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 with 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 Fig. 5 shows the suction mouth in a decoupled state from the rear. The outlet opening 27 is visible on the rear of the adapter unit 22. In the present case, the adapter outlet opening 27 is formed in that the rear of the adapter unit 22 is designed to be open. The adapter unit 22 is thus limited to the front side only by a cover 26, by side walls and by an upper 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 within the base unit 23 through the funnel 30 into the suction line 17. Towards the rear, the flow channel is delimited 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 Fig. 6 shows a sectional view through the center of the coupled suction mouth, ie a section through the suction mouth according to FIG 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 Fig. 7 shows an alternative adapter unit, which comprises projections 43. The adapter unit 22 can be coupled to the base unit by the Suction vehicle drives over adapter unit 22, grips around by means of gripping elements 44 which are arranged on the suction vehicle, and thus couples 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 Fig. 8 FIG. 10 shows a vacuum vehicle with a scrubbing device 40 and FIG Fig. 9 shows a suction vehicle with a mowing device 41. With these two suction vehicles, too, the base unit 23 can be raised and lowered within the vehicle.
