Abstract

A chassis frame is supported on a front steering axle and a rear steering axle. Between the two axles and beneath the chassis frame, a hollow support serving as a main blow duct is pivotingly disposed. Raisably and lowerably connected to the support via levers is a sweeping-brush roller. Connected to the support are blowing nozzles which lead air supplied by a fan mounted on the chassis frame into a blow duct formed by a cover plate disposed in front of the sweeping-brush roller. Disposed within the blow duct are two suction ports which are connected via dirt-suction pipes to a vacuum-sweepings container disposed on the chassis frame. The outlet of the vacuum-sweeings container is connected at a dismantling point to an air-suction duct which is in turn connected to the intake of the fan. This cleaning vehicle can be used for snow clearance by opening a flap and closing another flap in an air-outlet pipe piece and by moving an operating lever from a middle position into either of two end positions.

Description

Die Erfindung betrifft ein Reinigungsfahrzeug gemäss dem Oberbegriff des Patentanspruches 1.The invention relates to a cleaning vehicle according to the preamble of patent claim 1.

In der unter der Nummer 0 189 371 veröffentlichten europäischen Patentanmeldung ist eine Schneeräumungsma­schine mit einem Fahrgestellrahmen beschrieben, der auf eine vordere Lenkachse und eine hintere Achse abgestützt ist. Ein Fahrmotor dient zur Fortbewegung der Schneeräu­mungsmaschinen. Zwischen der vorderen und der hinteren Achse ist eine sich quer zur Längsrichtung der Maschine erstreckende Kehrbürstenwalze angeordnet. Ein hohler Trä­ger, der gleichzeitig als Blasluftkanal dient, ist schwenkbar auf der Unterseite des Fahrgestellrahmens an­geordnet und die Kehrwalze ist über Hebel anheb- und ab­senkbar am genannten Träger angelenkt. Die Ausgangsseite eines Ventilators ist an den Blasluftkanal angeschlossen, welcher die Blasluft auf verschiedene, in der Arbeits­richtung vor der Kehrbürstenwalze angeordnete Blasdüsen verteilt. Ein Arbeitsmotor dient zum Antreiben des Ven­tilators und der Kehrbürstenwalze. An der Frontseite der bekannten Schneeräumungsmaschine ist ein Schneepflug an­geordnet, der den grössten Teil des auf dem Boden liegen­den Schnees entsprechend seiner Schrägstellung zur Längs­achse der Maschine nach links oder rechts schiebt. Noch auf dem Boden verbleibende Schneereste werden von den ge­nannten Blasdüsen in der gleichen Richtung unterhalb des Fahrgestellrahmens zur Seite geblasen. Allfällig am Boden haftende Schneereste werden durch die Kehrbürstenwalze in den Bereich der Blasdüsen gekehrt und ebenfalls weggebla­sen. Diese bekannte Schneeräumungsmaschine eignet sich sehr gut zum Räumen der Start- und Landebahnen auf Flug­ häfen, jedoch nicht zur Sauberhaltung dieser Bahnen wäh­rend der schneefreien Zeit.The European patent application published under number 0 189 371 describes a snow removal machine with a chassis frame which is supported on a front steering axle and a rear axle. A traction motor is used to move the snow removal machines. A sweeping brush roller extending transversely to the longitudinal direction of the machine is arranged between the front and rear axles. A hollow support, which also serves as a blown air duct, is pivotably arranged on the underside of the chassis frame and the sweeping roller is articulated on the support mentioned above by means of levers. The outlet side of a fan is connected to the blast air duct, which distributes the blown air to various blower nozzles arranged in the working direction in front of the brush brush. A working motor is used to drive the fan and the brush roller. A snow plow is arranged on the front of the known snow-clearing machine and pushes most of the snow lying on the ground to the left or right in accordance with its inclination to the longitudinal axis of the machine. Remaining snow on the ground is blown to the side by the above-mentioned blowing nozzles in the same direction below the chassis frame. Any snow remnants adhering to the ground are swept by the sweeping brush roller into the area of the blowing nozzles and also blown away. This well-known snow removal machine is very well suited for clearing the runways during flight ports, but not to keep these tracks clean during the snow-free period.

Weiter ist beispielsweise aus der CH-PS Nr. 482 876 eine Vorrichtung zum Reinigen von Flächen mittels eines Luftstromes bekannt, welche Vorrichtung einen über die zu reinigende Fläche beweglichen Aufnahmekopf, ein Gebläse zum Erzeugen des Luftstromes am Aufnahmekopf und einen Sammelbehälter für den aufgenommenen Staub aufweist. Der Aufnahmekopf ist kastenförmig ausgebildet und längs des Randes sind elastische Vorhangelemente zum Bilden eines im wesentlichen geschlossenen Raumes auf der Unterseite des Aufnahmekopfes vorhanden. Der Aufnahmekopf besitzt ein durch einen Schlitz in den genannten Raum mündenden Druckluftkanal und einen aus dem Raum führenden Saugka­nal, durch den der durch die zugeführte Druckluft vom Bo­den aufgewirbelte Staub in den Sammelbehälter gesaugt wird. Mit dieser bekannten Vorrichtung kann nur vom schneefreien Boden Staub und Schmutz aufgenommen werden und diese Vorrichtung kann nicht zur Schneeräumung einge­setzt werden.Furthermore, for example from CH-PS No. 482 876 a device for cleaning surfaces by means of an air stream is known, which device has a pick-up head movable over the surface to be cleaned, a blower for generating the air stream on the pick-up head and a collecting container for the picked up dust . The receiving head is box-shaped and along the edge there are elastic curtain elements for forming a substantially closed space on the underside of the receiving head. The pick-up head has a compressed air duct opening through a slot in the space mentioned and a suction duct leading out of the space through which the dust whirled up by the supplied compressed air is sucked into the collecting container. With this known device, dust and dirt can only be absorbed from the snow-free ground and this device cannot be used for snow removal.

Den oben beschriebenen bekannten und teuren Einrich­tungen haftet der Nachteil an, dass sie nur zur Winter­zeit bzw. nur zur Sommerzeit eingesetzt werden können.The known and expensive devices described above have the disadvantage that they can only be used in winter or only in summer.

Es ist Aufgabe der Erfindung, ein Reinigungsfahrzeug zu schaffen, das gleichermassen als Grossflächenschnee­räumemaschine mit Schneeräumschild und Kehrblasgerät als auch als Grossflächen-Saugkehrmaschine geeignet ist, wo­durch das gleiche Reinigungsfahrzeug das ganze Jahr über eingesetzt werden kann, wodurch die Wirtschaftlichkeit erhöht wird.It is an object of the invention to provide a cleaning vehicle which is equally suitable as a large-area snow clearing machine with a snow blade and a sweeping blower, and also as a large-area suction sweeper, as a result of which the same cleaning vehicle can be used all year round, thereby increasing the economy.

Das erfindungsgemässe Reinigungsfahrzeug ist durch die im kennzeichnenden Teil des Patentanspruches 1 ange­führten Merkmale gekennzeichnet.The cleaning vehicle according to the invention is characterized by the features stated in the characterizing part of patent claim 1.

Besondere Ausführungsformen sind in den abhängigen Ansprüchen angegeben.Particular embodiments are specified in the dependent claims.

Das in den Fig. 1 bis 4 dargestellte Reinigungsfahr­zeug besitzt einen Fahrgestellrahmen 1, der über nicht dargestellte Mittel auf eine vordere lenkbare Planeten­achse 2 und eine hintere, wahlweise ebenfalls lenkbare Planetenachse 3 abgestützt ist. Im vorderen Bereich des Fahrgestellrahmens 1 befindet sich ein Fahrerhaus 4. Hin­ter und unterhalb des Fahrerhauses 4 ist ein Fahrmotor 5 angeordnet, welcher die vordere Planetenachse 2 und wahl­weise auch die hintere Planetenachse 3 antreibt. Eine nicht dargestellte, im Fahrerhaus 4 angeordnete Lenkungs­artumschaltevorrichtung gestattet, dass im Fahrerhaus je nach Bedarf auf die Vorderrad-, Allrad- oder Hundegang­lenkung geschaltet werden kann. Bei Allradlenkung folgt die Hinterachse genau der Spur der Vorderachse und be­wirkt damit zwangsläufig auch bei Kurvenfahrt eine Füh­rung des weiter unten näher beschriebenen Kehrblasgerätes in der Spur des Reinigungsfahrzeuges. Bei Umschaltung auf Hundeganglenkung schwenken alle vier Räder in der glei­chen Richtung aus, was zu einer Diagonalverschiebung des Reinigungsfahrzeuges führt. Damit kann Hindernissen aus­gewichen werden und die Manövrierarbeiten werden dadurch erleichtert.The cleaning vehicle shown in FIGS. 1 to 4 has a chassis frame 1, which is supported by means not shown on a front steerable planetary axis 2 and a rear, optionally also steerable planetary axis 3. In the front area of the chassis frame 1 there is a driver's cab 4. Behind and below the driver's cab 4 there is a drive motor 5 which drives the front planetary axle 2 and optionally also the rear planetary axle 3. A steering mode switching device (not shown) arranged in the driver's cab 4 allows the front wheel, four-wheel or dog-gear steering to be switched in the driver's cab as required. With all-wheel steering follows the rear axle exactly the track of the front axle and thus inevitably causes a guidance of the sweeping device described in more detail below in the track of the cleaning vehicle even when cornering. When switching to crab steering, all four wheels swivel in the same direction, which leads to a diagonal shift of the cleaning vehicle. Obstacles can be avoided and maneuvering is made easier.

Der Fahrgestellrahmen 1 ist im Bereich zwischen der vorderen und der hinteren Planetenachse 2 bzw. 3 durch Abkröpfung so ausgebildet, dass ein möglichst hoher Freiraum zwischen der Fahrbahn und dem Fahrgestellrahmen zur Aufnahme des genannten Kehrblasgerätes entsteht.The chassis frame 1 is formed in the area between the front and rear planetary axes 2 and 3 by cranking in such a way that the greatest possible free space is created between the roadway and the chassis frame for receiving the sweeper.

Im Bereich über der hinteren Planetenachse 3 ist ein Arbeitsmotor 6 angeordnet. Dieser treibt zwei oder je nach Bedarf mehr nicht dargestellte hydraulische Schwenk­kolbenpumpen an, die ihrerseits über zwei nicht darge­stellte Achsialkolbenmotoren ein leistungsstarkes Radial­gebläse 7 und einen nicht gezeichneten Kehrbürstenantrieb antreiben.A working motor 6 is arranged in the area above the rear planetary axis 3. This drives two or, as required, more hydraulic rotary piston pumps, which in turn drive a powerful radial blower 7 and a brush brush drive, not shown, via two axial piston motors, not shown.

Der Ausgang 8 des Radialgebläses 7 ist über eine Rohrleitung 9 mit einem hohlen Träger 10, der gleichzei­tig als Hauptblasluftkanal dient, verbunden. Der Träger 10 ist über eine am Fahrgestellrahmen 1 befestigte Drei­punktaufhängung 11 und einen am Träger 10 befestigten Drehkranz 12 um eine vertikale Achse schwenkbar mit dem Fahrgestellrahmen 1 verbunden. Von den beiden extremen Schwenkbewegungen des Trägers 10 sind in den Fig. 2 und 4 je eine strichpunktiert dargestellt. Mit dem Träger 10 ist über Lenker 13 eine Kehrbürstenwalze 14 verbunden, die über nicht dargestellte hydraulische Antriebszylinder vom Boden abgehoben bzw. darauf abgesenkt werden kann. Die Kehrbürstenwalze 14 ist zweiteilig ausgebildet und kann durch einen nicht dargestellten, in der Mitte der Kehrbürstenwalze 14 angeordneten Kettenantrieb in Drehung versetzt werden. Ein Ausführungsbeispiel eines solchen Kettenantriebes ist mit Bezug auf die Fig. 9 in der ein­gangs genannten, unter der Nummer 0 189 371 veröffent­lichten europäischen Patentanmeldung näher beschrieben.The outlet 8 of the radial blower 7 is connected via a pipeline 9 to a hollow support 10, which also serves as the main blowing air duct. The carrier 10 is connected to the chassis frame 1 via a three-point suspension 11 fastened to the chassis frame 1 and a turntable 12 fastened to the carrier 10 so that it can pivot about a vertical axis. Of the two extreme pivoting movements of the carrier 10, one in each case is shown in broken lines in FIGS. 2 and 4. With the carrier 10, a sweeping brush roller 14 is connected via a handlebar 13, which can be lifted off or lowered onto the floor via hydraulic drive cylinders (not shown). The sweeping brush roller 14 is formed in two parts and can be rotated by a chain drive, not shown, arranged in the middle of the sweeping brush roller 14. An embodiment of such a chain drive is described in more detail with reference to FIG. 9 in the European patent application mentioned at the beginning, published under number 0 189 371.

Ueber der Kehrbürstenwalze 14 befindet sich ein ge­krümmter Schutzschild 15, der sich über die ganze Länge der Kehrbürstenwalze 14 erstreckt. Der Schutzschild 15 bedeckt die obere Hälfte der Kehrbrüstenwalze 14 und ver­hindert, dass Schnee, Staub oder Schmutz von derselben nach oben geschleudert wird. Vom hinteren Ende des Schutzschildes 15 erstreckt sich ein Gummischutzlappen 16 nach unten. Auf der Frontseite der Kehrbürstenwalze 14 ist ein Abdeckblech 17 angeordnet, das zusammen mit der Kehrbürstenwalze 14 und dem Boden 18 einen sich über die ganze Länge der Kehrbürstenwalze 14 erstreckenden Blas­kanal 19 bildet.Above the sweeping brush roller 14 is a curved protective shield 15 which extends over the entire length of the sweeping brush roller 14. The protective shield 15 covers the upper half of the sweeper breast roller 14 and prevents snow, dust or dirt from being thrown upwards by the latter. A rubber protective flap 16 extends downward from the rear end of the protective shield 15. A cover plate 17 is arranged on the front of the sweeping brush roller 14 and, together with the sweeping brush roller 14 and the base 18, forms a blowing duct 19 which extends over the entire length of the sweeping brush roller 14.

Das in den Fig. 1 und 2 dargestellte Reinigungsfahr­zeug ist zum Schneeräumen vorbereitet. Zu diesem Zweck ist auf der Frontseite des Reinigungsfahrzeuges ein Schneepflug 20 bekannter Bauart montiert. Der Schneepflug 20 kann um eine vertikale Achse geschwenkt werden, damit der Schnee nach links oder nach rechts geschoben wird.The cleaning vehicle shown in FIGS. 1 and 2 is prepared for snow removal. For this purpose, a snow plow 20 of a known type is mounted on the front of the cleaning vehicle. The snow plow 20 can be pivoted about a vertical axis so that the snow is pushed to the left or to the right.

Die Fig. 5 zeigt in vereinfachter schaubildlicher Darstellung das für den Winterbetrieb eingestellte Kehr­blasgerät, das den als Hauptblaskanal dienenden Träger 10, welcher über den Drehkranz 12 und die Dreipunktauf­hängung 11 mit dem in der Fig. 5 nicht dargestellten Fahrgestellrahmen 1 um eine vertikale Achse schwenkbar verbunden ist, und die über in der Fig. 5 nicht gezei­chnete Lenker 13 anheb- und absenkbare Kehrbürstenwalze 14 umfasst. In der Mitte des Trägers 10 und unterhalb des Drehkranzes 12 ist eine einstellbare Umlenkvorrichtung 21 mit einer nicht sichtbaren und um eine horizontale Achse schwenkbare Luftumlenkklappe angeordnet, die über einen Bedienungshebel 22 in eine von drei Stellungen gebracht werden kann.FIG. 5 shows a simplified diagrammatic representation of the sweeper device set for winter operation, which connects the support 10 serving as the main blowing duct, which is pivotably connected about the vertical frame via the turntable 12 and the three-point suspension 11 to the chassis frame 1 (not shown in FIG. 5) 5, and comprises the sweeping brush roller 14, which can be raised and lowered via the handlebars 13, not shown in FIG. 5. An adjustable deflection device 21 is located in the center of the carrier 10 and below the turntable 12 arranged with an invisible and pivotable about a horizontal axis air deflection flap which can be brought into one of three positions via an operating lever 22.

In der in der Fig. 5 gezeigten Stellung des Bedie­nungshebels 22 ist die nicht sichtbare Luftumlenkklappe ebenfalls bezogen auf die Fig. 5 nach rechts verschwenkt, so dass alle über die Rohrleitung 9 in die Umlenkvorrich­tung 21 eintretende Luft in die linke Hälfte des Trägers 10 geführt wird. An der bezogen auf die Fig. 5 linken Hälfte des durch den Träger 10 gebildeten Hauptblasluft­kanals sind zwei Blasdüsen 23 und 24 angeschlossen, die durch das in der Fig. 5 nicht gezeichnete Abdeckblech 17 in den Blaskanal 19 münden und nach rechts gerichtet sind. An der bezogen auf die Fig. 5 rechten Hälfte des durch den Träger 10 gebildeten Hauptblasluftkanals sind zwei Blasdüsen 25 und 26 angeschlossen, die sich durch die nicht sichtbare Abdeckung 17 in den Blaskanal 19 er­strecken und nach links gerichtet sind. An jedem Ende des durch den Träger 10 gebildeten Hauptblasluftkanals ist je eine verschliessbare und in der Arbeitsrichtung hinter dem Gummischutzlappen 16 angeordnete Blasdüse 27 bzw. 28 angeschlossen. Diese beiden verschliessbaren Blasdüsen 27 und 28 sind aufeinander zu gerichtet.In the position of the operating lever 22 shown in FIG. 5, the invisible air deflection flap is also pivoted to the right in relation to FIG. 5, so that all air entering the deflection device 21 via the pipeline 9 is guided into the left half of the carrier 10 . On the left half of FIG. 5 of the main blowing air duct formed by the carrier 10, two blowing nozzles 23 and 24 are connected, which open into the blowing duct 19 through the cover plate 17, not shown in FIG. 5, and are directed to the right. On the right half of FIG. 5 of the main blowing air duct formed by the carrier 10, two blowing nozzles 25 and 26 are connected, which extend through the non-visible cover 17 into the blowing duct 19 and are directed to the left. At each end of the main blowing air duct formed by the carrier 10 there is a closable blowing nozzle 27 and 28, which is arranged behind the rubber protective flap 16 in the working direction. These two closable blow nozzles 27 and 28 are directed towards each other.

In der Arbeitsrichtung vor jeder Hälfte der Kehrbür­stenwalze 14 ist je ein Saugmund 29 bzw. 30 unter dem Ab­deckblech 17 angeordnet, siehe Fig. 1 und 2. Die Saugmün­der 29 und 30 sind über parallelogrammartige Lenker 31 mit der Unterseite des Trägers 10 verbunden und können mit Hilfe von nicht dargestellten hydraulischen Arbeits­zylindern in eine obere Stellung angehoben oder in die Arbeitsstellung abgesenkt werden. An jeden Saugmund 29 und 30 ist je ein Schmutzsaugrohr 32 bzw. 33 angeschlos­sen.In the working direction in front of each half of the sweeping brush roller 14, one suction mouth 29 or 30 is arranged under the cover plate 17, see FIGS. 1 and 2. The suction mouths 29 and 30 are connected to the underside of the carrier 10 via parallelogram-type links 31 and can be used with With the help of hydraulic working cylinders, not shown, be raised to an upper position or lowered into the working position. A dirt suction pipe 32 or 33 is connected to each suction mouth 29 and 30.

Auf der Oberseite der Rohrleitung 9 ist ein Luftauslassstutzen 34 angeordnet, der mittels einer ge­strichelt angedeuteten Klappe 35 verschliessbar ist. Die Klappe 35 kann durch einen Bedienungshebel 36 betätigt werden.An air outlet connection 34 is arranged on the top of the pipeline 9 and can be closed by means of a flap 35 indicated by dashed lines. The flap 35 can be operated by an operating lever 36.

Wie schon erwähnt, ist das in der Fig. 5 gezeigte Kehrblasgerät für den Winterbetrieb, d.h. zur Schneeräu­mung, eingestellt. Die Bedienungshebel 22 und 36 befinden sich in der gezeichneten Stellung, so dass die gesamte vom Radialgebläse 7 geförderte Luftmenge in die bezogen auf die Fig. 5 linke Hälfte des durch den Träger 10 ge­bildeten Hauptblasluftkanals und somit zu den Blasdüsen 23, 24 und 27 gelangt. Durch die gleichgerichteten Blas­düsen 23 und 24 wird innerhalb des Blaskanals 19, siehe Fig. 1, vor der Kehrbürstenwalze 14 ein Luftstrom er­zeugt, der allen im Blaskanal 19 befindlichen losen Schnee bezogen auf die Fig. 5 nach rechts befördert. Al­lenfalls am Boden 18 haftender Schnee wird von der nach­folqenden Kehrbürstenwalze 14, die in der Richtung des Pfeiles 37 angetrieben wird, in den Blaskanal 19 gebür­stet und vom genannten Luftstrom erfasst. Schliesslich wird ein hinter der Kehrbürstenwalze 14 allfällig zurück­bleibender Rest von losem Schnee durch die Blasdüse 27 weggeblasen.As already mentioned, the reverse sweeper shown in Fig. 5 is for winter operation, i.e. for clearing snow. The operating levers 22 and 36 are in the position shown, so that the entire amount of air conveyed by the radial fan 7 reaches the left-hand half of the main blowing air duct formed by the carrier 10 in relation to FIG. 5 and thus to the blowing nozzles 23, 24 and 27. The rectified blowing nozzles 23 and 24 generate an air flow within the blowing duct 19, see FIG. 1, in front of the sweeping brush roller 14, which carries all the loose snow in the blowing duct 19 to the right in relation to FIG. 5. At most, snow adhering to the ground 18 is brushed into the blowing duct 19 by the following sweeping brush roller 14, which is driven in the direction of the arrow 37, and is captured by the air flow mentioned. Finally, any remaining snow remaining behind the sweeping brush roller 14 is blown away by the blowing nozzle 27.

Die für die Schneeräumung nicht benötigten Saugmün­der 29 und 30 befinden sich in ihrer obersten Stellung, damit der genannte Luftstrom möglichst wenig behindert wird.The suction mouths 29 and 30 which are not required for snow removal are in their uppermost position so that the air flow mentioned is hampered as little as possible.

Falls der Schnee durch das Kehrblasgerät bezogen auf die Fig. 5 nach links befördert werden soll, so wird der Bedienungshebel 22 in die andere Endstellung verbracht, was zur Folge hat, dass die vom Radialgebläse 7 geförderte Luft in die rechte Hälfte des durch den Träger 10 gebildeten Hauptblasluftkanals und zu den Düsen 25, 26 und 28 gelangt.5, the operating lever 22 is moved to the other end position, with the result that the air conveyed by the radial blower 7 into the right half of the through the carrier 10th formed main blowing air channel and to the nozzles 25, 26th and 28 arrives.

Die Fig. 3 und 4 zeigen das Reinigungsfahrzeug, das für den Saugkehrbetrieb vorbereitet ist. Zu diesem Zweck ist auf den Fahrgestellrahmen 1 ein Kehrgutsaugbehälter 38 aufgesetzt, der zum Entleeren um eine horizontale Ach­se 39 kippbar ist. Die Rückseite des Kehrgutsaugbehälters 38 ist durch einen Verschlussdeckel 40 dicht verschliess­bar. Die Schmutzsaugrohre 32 und 33 sowie eine mit dem Eingang 41 des Radialgebläses 7 verbindbarer Luftsaug­kanal 42 sind über eine in einer geneigten Ebene angeord­nete Trennstelle 43 lösbar an den Kehrgutsaugbehälter 38 angeschlossen. Innerhalb des Kehrgutsaugbehälters 38 be­findet sich ein gestrichelt angedeutetes Filtersieb 44, das den angesaugten Schmutz vom Radialgebläse 7 fernhält. Das in der Fig. 6 dargestellte Kehrblasgerät ist für den Kehrsaugbetrieb eingestellt. Der Bedienungshebel 22 be­findet sich in der Mittelstellung, so dass Luft in beide Hälften des durch den Träger 10 gebildeten Hauptblasluft­kanals und zu den Blasdüsen 23, 24, 25 und 26 gelangt. Die hinter dem Gummischutzlappen 16 angeordneten Blasdü­sen 27 und 28 sind durch nicht dargestellte Mittel, z.B. passende Deckel, verschlossen. Weiter ist die Klappe 35 im Luftauslassstutzen 34 teilweise geöffnet, so dass ein Teil der durch das Radialgebläse 7 geförderten Luft ins Freie austreten kann. Auf diese Weise entsteht im Blas­kanal 19 ein leichter Unterdruck, wodurch verhindert wird, dass Staub aus dem Blaskanal 19 austritt. Im Kehr­gutsaugbehälter 38 integriert, oder aber ausserhalb des­selben, kann ein nicht dargestellter Wassertank für die nicht näher dargestellte Wassersprühanlage, die für die Staubbindung üblicherweise erforderlich ist, angeordnet sein.3 and 4 show the cleaning vehicle, which is prepared for the vacuum sweeping operation. For this purpose, a dirt hopper 38 is placed on the chassis frame 1, which can be tilted about a horizontal axis 39 for emptying. The rear of the sweepings suction container 38 can be closed tightly by a closure cover 40. The dirt suction pipes 32 and 33 and an air suction duct 42 which can be connected to the inlet 41 of the radial blower 7 are detachably connected to the sweeping material suction container 38 via a separation point 43 arranged in an inclined plane. Within the sweeping material suction container 38 there is a filter screen 44, indicated by dashed lines, which keeps the suctioned dirt away from the radial fan 7. The sweeper shown in Fig. 6 is set for sweeping operation. The operating lever 22 is in the middle position, so that air reaches both halves of the main blowing air duct formed by the carrier 10 and the blowing nozzles 23, 24, 25 and 26. The blowing nozzles 27 and 28 arranged behind the rubber protective flap 16 are by means not shown, e.g. matching lid, closed. Furthermore, the flap 35 in the air outlet connection 34 is partially open, so that part of the air conveyed by the radial fan 7 can escape to the outside. In this way, a slight negative pressure is created in the blow duct 19, which prevents dust from escaping from the blow duct 19. Integrated in the sweepings suction container 38 or outside it, a water tank (not shown) can be arranged for the water spray system (not shown in more detail), which is usually required for dust binding.

Die Saugmünder 29 und 30 werden in die Arbeits­stellung abgesenkt und die Kehrbürstenwalze 14 wird ver­ gleichsweise zum Schneeräumbetrieb mit reduzierter Dreh­zahl in Richtung des Pfeiles 37 angetrieben. Das Radial­gebläse 7 saugt Luft durch die Saugmünder 29 und 30, die Schmutzsaugrohre 32 und 33, den Kehrgutsaugbehälter 38 mit dem Filtersieb 44 und den Luftansaugkanal 42 an und bewirkt dadurch bei geschlossener Klappe 45, dass im Kehrgutsaugbehälter 38, den Saugrohren 32 und 33 und den Saugmündern 29 und 30 ein Unterdruck entsteht. Die Klappe 45 wird geöffnet, wenn bei vorbereitetem Winterbetrieb des Reinigungsfahrzeuges der Kehrgutsaugbehälter 38 nicht demontiert wird.The suction mouths 29 and 30 are lowered into the working position and the brush roller 14 is ver equally driven for snow clearing operation at reduced speed in the direction of arrow 37. The radial blower 7 draws air through the suction mouths 29 and 30, the dirt suction pipes 32 and 33, the sweepings suction container 38 with the filter sieve 44 and the air suction duct 42 and thereby causes, when the flap 45 is closed, that in the sweepings suction container 38, the suction pipes 32 and 33 and the Suction mouths 29 and 30 creates a negative pressure. The flap 45 is opened when the sweeping material suction container 38 is not dismantled when the cleaning vehicle is in winter operation.

In den Saugmündern 29 und 30, und wenn erforderlich schon ausserhalb derselben, wird durch Zuführen von ge­ringen Sprühwassermengen aus dem nicht dargestellten Was­serbehälter der Staub gebunden, so dass die durch das Filtersieb 44, das Radialgebläse 7 angesaugte resp. aus­geblasene Luft möglichst staubfrei ist. Die Kehrbürsten­walze 14 unterstützt die Arbeit der Blasdüsen 23 bis 26, indem sie festgesetzten Schmutz bzw. von den Blasdüsen nicht entferntes Kehrgut löst und in den Bereich der Blasdüsen 23 bis 26 vorwirft bzw. direkt von hinten den Saugmündern 29 und 30 zuführt.In the suction mouths 29 and 30, and if necessary outside the same, the dust is bound by supplying small amounts of spray water from the water tank (not shown), so that the radial fan 7 sucked in through the filter screen 44, respectively. blown air is as dust-free as possible. The sweeping brush roller 14 supports the work of the blowing nozzles 23 to 26 by loosening stuck dirt or debris not removed from the blowing nozzles and throwing them into the area of the blowing nozzles 23 to 26 or feeding them directly from behind to the suction mouths 29 and 30.

Auf diese Weise ist es möglich, durch geringe Um­stellarbeiten das gleich Reinigungsfahrzeug mit dem glei­chen Arbeitsaggregat sowohl als leistungsfähiges Kehr­blasfahrzeug zum Schneeräumen als auch als ebenso lei­stungsfähiges Kehrsaugfahrzeug zu verwenden und dadurch eine Ganzjahresarbeitsmaschine mit all ihren Vorteilen zu schaffen. Für die Bedienungsmannschaft wird die Handha­bung somit vertrauter und damit der Einsatz sicherer. Die dauernde Einsatzbereitschaft wird besser sichergestellt und der Platzbedarf für die Unterbringung insgesamt ist geringer.In this way, it is possible to use the same cleaning vehicle with the same work unit as a powerful sweeper for clearing snow as well as an equally powerful sweeper, and thus create a year-round work machine with all its advantages. For the operating team, the handling becomes more familiar and thus the use safer. The permanent operational readiness is better ensured and the overall space requirement for the accommodation is less.
