Erfindungsgemäss wurde die Aufgabe dadurch gelöst, dass das durch eine Saugluftöffnung mit dem Innenraum des Kehrichtsammelbehälters leitungsverbundene Saugluftaggregat, Strömungsmaschine oder Ventilator an der mit einer inneren Rutschfläche versehenen Aussenseite der Rückwand des Kehrichtsammelbehälters angeordnet ist.According to the invention, the object was achieved in that the suction air unit, flow machine or fan, which is connected by a suction air opening to the interior of the waste collecting container, is arranged on the outside of the rear wall of the waste collecting container, which is provided with an inner sliding surface.

Dadurch kann bei bestehenden gleichbleibenden Aussenkonturen ein grösseres Nutzvolumen resp. eine Produktionssteigerung der erzielt werden.As a result, with existing constant outer contours, a larger usable volume, respectively. an increase in production that can be achieved.

Es erweist sich weiter als vorteilhaft, wenn die obere Behälterwand mit der benachbarten Abscheidevorrichtung einen dem Saugluftaggregat vorgeschalteten ersten Abschnitt einer mit dem Saugluftaggregat verbundenen Luftaustrittsleitung für die vom Kehricht getrennte Saugluft bildend, leitungsverbunden ist.It also proves to be advantageous if the upper container wall is line-connected to the adjacent separating device to form a first section of an air outlet line connected to the suction air unit, upstream of the suction air unit, for the suction air separated from the refuse.

Dadurch können eine gleichmässig verteilte Befüllung des Kehrichtsammelbehälters erreicht und zusätzliche Lärmessionen ausgeschlossen werden.This means that the refuse bin can be filled evenly and that additional noise measurements are excluded.

Wenn ein dem Saugluftaggregat nachgeführter zweiter Abschnitt die Auslassöffnung am Ende der Luftaustrittsleitung bildet, kann ein Vorteil erzielt werden, indem beispielsweise durch eine lange (gefalzte) Siebfläche der Abscheidevorrichtung gegenüber der oberen Behälterwand sich die Verstopfungsgefahr im Luftauslassbereich und die Staub- und Wasserabscheidung mindert.If a second section following the suction air unit forms the outlet opening at the end of the air outlet line, an advantage can be achieved in that, for example, a long (folded) sieve surface of the separating device opposite the upper container wall reduces the risk of clogging in the air outlet area and the separation of dust and water.

Es ist vorteilhaft, wenn der nachgeführte zweite Abschnitt der Luftaustrittsleitung nach dem Sauggebläse unterhalb des Kehrichtsammelbehälters endet, damit keine unerwünschten Störfaktoren wie beispielsweise zusätzliche Lärmemissionen, entstehen.It is advantageous if the following, second section of the air outlet line ends after the suction fan below the refuse bin so that no undesirable disruptive factors such as additional noise emissions arise.

Vorzugsweise verläuft der zweite Abschnitt der Luftaustrittsleitung an der Unterseite des Kehrichtsammelbehälters und kann dort geschützt, lärmisoliert und unauffällig befestigt werden.The second section of the air outlet line preferably runs on the underside of the refuse container and can be attached there in a protected, noise-insulated and inconspicuous manner.

Es erweist sich als zweckmässig, wenn die Aussenseite der Rückwand des Kehrichtsammelbehälters zur Anordnung eines aus den leitungsverbundenen Saugluftaggregat, ersten und zweiten Abschnitt gebildeten Zwischenabschnitt der Luftaustrittsleitung ausgebildet ist, eine Anordnungsweise ergibt, die den Zugang und die Servicefreundlichkeit zu den beanspruchten Komponenten der Luftverteilung einfach macht.It proves to be expedient if the outside of the rear wall of the refuse container is designed for the arrangement of an intermediate section of the air outlet line formed from the line-connected suction air unit, first and second section, resulting in an arrangement that makes access and serviceability to the claimed components of the air distribution easy .

Bei dem ein rotierendes Saugluftgebläse, oder einen anderen Saugluft erzeugenden Generator aufweisenden Saugluftaggregat, kann eine Rotationsachse des Schaufelrades senkrecht zur geneigten Rückwand des Kehrichtsammelbehälters an der Rückwandaussenseite angeordnet sein, sodass eine kompakte und geschützte Anordnung der betroffenen Anlagenteile an der Rückwandaussenseite entstehen kann.In the case of the suction air unit having a rotating suction air fan or another generator producing suction air, a rotation axis of the paddle wheel can be arranged perpendicular to the inclined rear wall of the refuse collection container on the outside of the rear wall, so that a compact and protected arrangement of the affected system parts can be created on the outside of the rear wall.

Es kann zweckmässig sein, eine Ansaugöffnung des Saugluftgebläses in dem durch das Saugluftaggregat gebildeten Zwischenabschnitt der Luftaustrittsleitung vor dem Saugluftgebläse vorzusehen, der ein bedeutender Abschnitt des Saugluftsystems bildet.It can be useful to provide a suction opening of the suction air blower in the intermediate section of the air outlet line formed by the suction air unit in front of the suction air blower, which forms a significant section of the suction air system.

Es ist vorteilhaft, wenn die Ansaugöffnung des Saugluftgebläses dem ersten Abschnitt der Luftaustrittsleitung zugeordnet ist, die eine einfache Leitungsverbindung gestattet.It is advantageous if the suction opening of the suction air blower is assigned to the first section of the air outlet line, which allows a simple line connection.

Dementsprechend ist es zweckmässig, wenn dem Saugluftgebläse eine in der Luftaustrittsleitung gegenüber der Ansaugöffnung versetzte, mit dem zweiten Abschnitt der Luftaustrittsleitung nach dem Saugluftgebläse leitungsverbundene Luftauslassöffnung zugeordnet ist, wodurch die Luftführung strömungstechnisch optimiert werden kann.Accordingly, it is useful if the suction air fan has one in the air outlet line relative to the suction opening, is assigned to the second section of the air outlet line after the suction air blower line-connected air outlet opening, whereby the air flow can be optimized.

Vorzugsweise sind die Teil des ersten Abschnitts der Luftaustrittsleitung -flach ausgebreiteten Abschnitt bildenden- obere Behälterwand und die Abscheidevorrichtung an einem zur Entleerung des Kehrichtsammelbehälters vorgesehenen Behälterdeckel angeordnet, der um eine quer zur Fortbewegungsrichtung F gerichtete, horizontale Achse schwenkbar ausgebildet ist und eine zum Zwischenabschnitt der Luftaustrittsleitung trennbare Leitungsverbindung aufweist, wobei dadurch im Behälterdeckelbereich ein flacher, breit ausgelegter Strömungsquerschnitt entstehen kann.Preferably, the part of the first section of the air outlet line -flat section forming the upper container wall and the separating device are arranged on a container cover provided for emptying the refuse container, which is designed to be pivotable about a horizontal axis directed transversely to the direction of movement F and one to the intermediate section of the air outlet line Has separable line connection, whereby a flat, broadly designed flow cross-section can thereby arise in the container cover area.

Wenn der Zwischenabschnitt der Luftaustrittsleitung durch einen an der Aussenseite der Rückwand dem Saugluftgebläse resp. dessen Ansaugöffnung vorgeschalteten, sich nach unten bzw. zur Ansaugöffnung hin verjüngend ersteckenden Trichter ausgebildet ist, entsteht eine strömungstechnisch begünstigte Auslegung der von den Luftaustrittsleitungsabschnitten und dem Saugluftaggregat betroffenen Anlageteile.If the intermediate section of the air outlet line by a suction fan on the outside of the rear wall, respectively. whose suction opening is formed upstream and tapering downwards or towards the suction opening, a flow-optimized design of the system parts affected by the air outlet line sections and the suction air unit is created.

Im Sinne einer unterstützten Abscheidung der Festteile im Kehrichtsammelbehälter, ist an dem Förderende der Saugleitung ein in den Kehrichtsammelbehälter ragender, die Saugluft zum Behälterboden lenkender Auslassdiffusor angeordnet, der den Förderstrom ausdehnt und entspannt.For the purpose of assisted separation of the solid parts in the refuse collection container, an outlet diffuser protruding into the refuse collection container and directing the suction air to the container bottom is arranged at the conveying end of the suction line, which expands and relaxes the conveying flow.

Der sich wenigstens teilweise über die Breite des Kehrichtsammelbehälters erstreckende Auslassdiffusor ist an seiner Unterseite zur Optimierung seiner Wirkung offen ausgebildet.The outlet diffuser, which extends at least partially over the width of the waste collecting container, is designed to be open on its underside in order to optimize its effect.

Um auf die Umlenkung des Luftstroms verstärkt einwirken zu können, ist anschliessend an den Auslassdiffusor eine die Luftführung verlängernde schwenkbare Klappe angeordnet.In order to be able to act more intensely on the deflection of the air flow, a pivotable flap which extends the air duct is arranged next to the outlet diffuser.

Fig. 1 veranschaulicht eine selbstfahrende Kehrmaschine 1, mit einem aus zwei, an einer senkrechten Schwenkachse 2 verbundenen Fahrgestellteilen 3, 4 eines Fahrgestells 5. Das vordere Fahrgestellteil 3 weist eine aus zwei gemeinsam lenkbaren Rädern 6 ausgestattete Fahrachse 7 auf, wogegen die Räder 8 des hinteren Fahrgestellteils 4 an einer starren Fahrachse 9 gelagert sind, wobei in Fig. 1 jeweils nur das eine Rad einer Achse dargestellt ist. Fig. 1 illustrates a self-propelled sweeper 1, with one of two chassis parts 3, 4 of a chassis 5 connected to a vertical pivot axis 2. The front chassis part 3 has a chassis 7 equipped with two jointly steerable wheels 6, whereas the wheels 8 of the rear chassis part 4 are mounted on a rigid axle 9, wherein in Fig. 1 only one wheel of an axle is shown.

Die Arbeits- bzw. Fortbewegungsrichtung der 1 ist in der Fig. 1 mit F bezeichnet.The direction of work or movement of FIG. 1 is in FIG Fig. 1 denoted by F.

Am vorderen Fahrgestellteil 3 ist vor den vorderen Rädern 6 jeweils eine auf der Bodenfläche drehende Kehrbürste 10 gelagert, die mittels Motor um eine etwa senkrechte Achse rotierend antreibbar ist/sind.A sweeping brush 10 rotating on the floor surface is mounted on the front chassis part 3 in front of the front wheels 6 and can be driven to rotate about an approximately vertical axis by means of a motor.

Die Kehrbürsten kehren das auf der Bodenfläche 11 liegende Kehrgut an/unter eine Absaugvorrichtung 12, die den Kehricht von der Bodenfläche 11 ansaugt und über eine mit einem Saugluftaggregat 13 verbundene Saugleitung (Steigleitung) 14 durch die Luftströmung in einen auf dem hinteren Fahrgestellteil 4 des Fahrgestells 5 abgestellten Kehrichtsammelbehälter 15 fördert.The sweeping brushes sweep the debris lying on the floor surface 11 to / under a suction device 12, which sucks the debris from the floor surface 11 and through a suction pipe (riser pipe) 14 connected to a suction air unit 13 through the air flow into one on the rear chassis part 4 of the chassis 5 parked garbage collector 15 promotes.

Auf dem vorderen Fahrgestellteil 3 des Fahrgestells 5 ist eine Fahrerkabine 16 befestigt, in der eine Bedienungsperson die Kehrmaschine 1 betreibt.A driver's cab 16, in which an operator operates the sweeping machine 1, is attached to the front chassis part 3 of the chassis 5.

Der hintere Fahrgestellteil 4 weist einen Aufbau 17 auf, der -vorliegend im wesentlichen- aus einem zur Aufnahme des über die Saugleitung 14 geführten Kehrichts dienenden Kehrichtsammelbehälter 15 und einem mit diesem förderwirksam verbundenen Saugluftaggregat 13 sowie einer Luftaustrittsleitung 26 besteht.The rear chassis part 4 has a structure 17 which - in the present case essentially - consists of a refuse collection container 15 serving to receive the refuse guided via the suction line 14 and a suction air unit 13 connected to it for conveying purposes, as well as an air outlet line 26.

Der aufgebaute Kehrichtsammelbehälter 15 nimmt den Kehricht auf, der durch die Ansaugvorrichtung 12 von der Bodenfläche 11 angehoben, danach über die ansteigende Saugleitung 14, -deren Förderende vorzugsweise einen in den Behälter 15 mündenden Auslassdiffusor 18 aufweist-, durch die von dem Saugluftaggregat 13 erzeugten Vakuum-/Unterdruckbedingungen gefördert wird.The built-up refuse collection container 15 receives the refuse, which is lifted by the suction device 12 from the floor surface 11, then over the rising surface Suction line 14, whose conveying end preferably has an outlet diffuser 18 opening into the container 15, through which the vacuum / negative pressure conditions generated by the suction air unit 13 are conveyed.

Der Auslassdiffusor 18 unterstützt die Trennung des Kehrichts von der Saugluft durch Entspannung/Ausdehnung letzterer im Kehrichtsammelbehälter 15 und weist zu diesem Zweck einen sich in Richtung Luftstrom stetig erweiternden Querschnitt auf, der sich vorteilhaft wenigstens annähernd auf die Kehrichtsammelbehälterbreite erstrecken kann.The outlet diffuser 18 supports the separation of the refuse from the suction air by expanding / expanding the latter in the refuse container 15 and, for this purpose, has a cross-section that continuously widens in the direction of the airflow and can advantageously extend at least approximately to the width of the refuse container.

Im Sinne einer Ausdehnung des Luftstroms an dem in den Kehrichtbehälter ragenden Förderende der Saugleitung 14 ist der Auslassdiffusor 18 haubenartig bzw. nach unten offen ausgebildet.In the sense of an expansion of the air flow at the conveying end of the suction line 14 protruding into the refuse container, the outlet diffuser 18 is designed like a hood or open at the bottom.

Vorzugsweise bildet der Diffusor 18 ein in den Kehrichtsammelbehälter 15 ragendes, gebogenes Ende der Luftleitung 14 -ein Krümmer-, der an dem Kehrichtsammelbehälter 15 befestigt ist und zur Entleerung letzterens, eine vorzugsweise ausserhalb des Kehrichtbehälters 15 sich befindende Trennstelle 19 aufweist, von der der Diffusor 18 bei der Entleerung des Kehrichtsammelbehälters 15 von der Saugleitung 14 getrennt ist.The diffuser 18 preferably forms a curved end of the air line 14 protruding into the refuse collection container 15 -a bend- which is attached to the refuse collection container 15 and, for emptying the latter, has a separating point 19, preferably outside the refuse container 15, from which the diffuser 18 is separated from the suction line 14 during the emptying of the refuse container 15.
