Abstract

2.1. In refuse collection vehicles, in which the filled and removed refuse collection container for intermediate storage, e.g. for a recycling, performs a transporting and storing function for the refuse, considerable space on the chassis is wasted because the refuse is filled into the compression device and is conveyed from this into the refuse collection container. The new refuse collection vehicle is intended to combine a simple construction with an optimum refuse-holding capacity. 2.2. For this purpose, the path of the pusher element (16) extends through the opening (8, 8') into the refuse collection container (5, 5'), so that the compression element in the refuse collection container can be moved to and fro, the refuse-filling opening (7) is furthermore arranged on the refuse collection container, so that the refuse can be compressed solely in the refuse collection container, and, finally, the opening (8, 8') is closed by the compression element (V) when the refuse collection container is situated on the chassis. This gives a simple construction in combination with optimum holding capacity of the refuse collection container. The simple compression device requires little space behind the driver's cab when the refuse collection container is filled directly. 2.3. The refuse collection vehicle is especially suitable for an environmentally conscious refuse disposal with intermediate storage and recycling. <IMAGE>

Description

Die Erfindung betrifft ein Müllsammelfahrzeug der im Oberbegriff des Patentanspruchs 1 angegebenen Art.The invention relates to a refuse collection vehicle of the type specified in the preamble of claim 1.

Bei einem aus der DE-PS 34 01 069 bekannten Müllsammelfahrzeug dieser Art ist die Verdichtungsvorrichtung mit dem Verdichtungselement, teilweise das tiefergesetzte Fahrerhaus überbauend, mit einem Einfülltrichter und einem Zwischenspeicherraum für den Müll versehen, wofür verhältnismäßig viel Platz zwischen dem Müllsammelbehälter und dem Fahrerhaus benötigt wird. Das Fassungsvermögen des Müllsammelbehälters ist aus diesem Grund beschränkt. Ferner wird ein unzweckmäßig hoher Anteil der Nutzlast des Fahrzeuges für die schweren Teile der Verdichtungsvorrichtung, des Einfülltrichters und der Zwischenspeicherkammer vergeudet. Da das Verdichtungselement in der Zwischenspeicherkammer arbeitet und bei zunehmender Füllung des Müllsammelbehälters seine Verdichtungswirkung aus der Zwischenspeicherkammer bis in den Innenraum des Müllsammelbehälters ausübt, ist eine aufwendige und belastbare Kopplung zwischen dem Müllsammelbehälter und der Verdichtungsvorrichtung erforderlich.In a refuse collection vehicle of this type known from DE-PS 34 01 069, the compaction device with the compaction element, partially overbuilding the driver's cab, is provided with a filling funnel and an intermediate storage space for the refuse, for which a relatively large amount of space is required between the refuse collection container and the driver's cab . For this reason, the capacity of the waste collection container is limited. Furthermore, an unusually high proportion of the payload of the vehicle is wasted on the heavy parts of the compression device, the hopper and the intermediate storage chamber. Since the compression element works in the intermediate storage chamber and exerts its compacting effect from the intermediate storage chamber into the interior of the waste collection container as the refuse collection container fills up, a complex and resilient coupling between the refuse collection container and the compression device is required.

Auch bei einem aus der DE-OS 25 45 051 bekannten Müllsammelfahrzeug dieser Art ist zwischen dem Müllsammelbehälter und dem Fahrerhaus ein Ladewerk mit einem Zwischenspeicherraum für den Müll vorgesehen und dadurch die zum Befüllen nutzbare Länge des Müllsammelbehälters beschränkt. Zwei relativ zueinander schwenkbare Klappen überführen den in das Ladewerk eingefüllten Müll durch die Öffnung in den Müllsammelbehälter. Ein Verdichten des Mülls findet im wesentlichen nur zwischen diesen beiden Klappen statt, so daß der Verdichtungsgrad des Mülls im Müllsammelbehälter gering ist. Die eine der beiden Klappen ist mit ihrem Antrieb am Müllsammelbehälter angeordnet, so daß aufgrund dieses hohen technischen Aufwandes der Müllsammelbehälter für zwischenzulagernden Müll nur unrationell einsetzbar ist.Also in a refuse collection vehicle of this type known from DE-OS 25 45 051, a loading unit with an intermediate storage space for the refuse is provided between the refuse collection container and the driver's cab, and thereby the length of the refuse collection container that can be used for filling limited. Two flaps, which can be swiveled relative to one another, transfer the garbage filled into the loading plant through the opening into the garbage collection container. The garbage is compacted essentially only between these two flaps, so that the degree of compaction of the garbage in the garbage collection container is low. One of the two flaps is arranged with its drive on the waste collection container, so that due to this high technical outlay, the waste collection container can only be used inefficiently for intermediate waste.

Auch bei einem aus der DE-OS 15 31 769 bekannten Müllsammelfahrzeug wird der Müll zunächst in das Ladewerk eingefüllt und dann von diesem aus in den Müllsammelbehälter überführt, wobei bei gegebener Fahrzeuglänge die zum Befüllen nutzbare Länge des Müllsammelbehälters begrenzt ist. Außerdem enthält der Müllsammelbehälter eine aufwendige Mechanik zum Verschließen der Verbindungsöffnung zum Ladewerk, was seinen Einsatz zur Zwischenlagerung des gesammelten Mülls unrationell macht.Also in a refuse collection vehicle known from DE-OS 15 31 769, the refuse is first filled into the loading plant and then transferred from there into the refuse collection container, the length of the refuse collection container usable for filling being limited for a given vehicle length. In addition, the waste collection container contains a complex mechanism for closing the connection opening to the loading plant, which makes its use for intermediate storage of the collected waste inefficient.

Früher, als die Müllentsorgung noch unter anderen Gesichtspunkten ablief, war es üblich in den Müllsammelbehälter bereits die Verdichtungsvorrichtung baulich zu integrieren und den Müll direkt in den Müllsammelbehälter einzufüllen. Für die moderne Müllentsorgung mit Zwischenlagerung des gefüllten Müllsammelbehälters ist dieses Prinzip unzweckmäßig, weil diese Müllsammelbehälter für die Zwischenlagerung oder das Recycling unrationell sind, wenn sie mit der schweren, dann nicht mehr benötigten Verdichtungsvorrichtung vom Müllsammelfahrzeug getrennt transportiert und zwischengelagert werden. Außerdem ist dies für den Betreiber des Müllsammelfahrzeuges außerordentlich kostenaufwendig, weil er für diese Art der Müllentsorgung eine große Anzahl solcher teurer und schwerer Müllsammelbehälter bereithalten muß, um das Müllsammelfahrzeug zum Müllsammeln auslasten zu können.In the past, when the garbage disposal took place from other points of view, it was customary to integrate the compacting device structurally into the garbage collection container and to fill the garbage directly into the garbage collection container. This principle is unsuitable for modern waste disposal with intermediate storage of the filled waste collection container, because these waste collection containers are inefficient for intermediate storage or recycling if they are transported separately from the waste collection vehicle with the heavy, then no longer required compacting device. In addition, this is extremely costly for the operator of the refuse collection vehicle because he is for this type the garbage disposal must have a large number of such expensive and heavy garbage collection containers available in order to be able to utilize the garbage collection vehicle to collect garbage.

Der Erfindung liegt die Aufgabe zugrunde, ein modernes Konzept für ein Müllsammelfahrzeug anzugeben, das einen baulich einfachen und deshalb für die Entsorgung mit Zwischenlagerung geeigneten Müllsammelbehälter mit optimal großem Fassungsvermögen aufweist.The invention has for its object to provide a modern concept for a refuse collection vehicle, which has a structurally simple and therefore suitable for disposal with intermediate storage waste collection container with an optimally large capacity.

Die gestellte Aufgabe wird mit den im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmalen gelöst.The object is achieved with the features specified in the characterizing part of patent claim 1.

Weil der Müllsammelbehälter bei dieser Ausbildung, ggfs. ausgenommen das Verdichtungselement, keine aktiven Komponenten der Verdichtungsvorrichtung aufweist, ist er kostengünstig und einfach herstellbar und zur Zwischenlagerung des gesammelten Mülls rationell einzusetzen. Das Schubelement und die anderen aktiven Komponenten der Verdichtungsvorrichtung verbleiben am Fahrzeug, wenn der Müllsammelbehälter abgeladen ist. Da überdies ausschließlich der Müll im Inneren des Müllsammelbehälters verdichtet und dazu der Müllsammelbehälter direkt von oben befüllt wird, läßt sich die Vorderwand des vom Verdichtungselement verschließbaren Müllsammelbehälters ziemlich nahe an das Führerhaus heransetzen, wodurch bei gegebener Fahrzeuglänge ein optimal großes Fassungsvermögen für den Müllsammelbehälter erreicht wird.Because the refuse collection container in this configuration, possibly excluding the compaction element, has no active components of the compaction device, it is inexpensive and easy to manufacture and can be used efficiently for the intermediate storage of the collected refuse. The thrust element and the other active components of the compacting device remain on the vehicle when the waste collection container is unloaded. In addition, since only the garbage inside the garbage collection container is compressed and the garbage collection container is filled directly from above, the front wall of the garbage collection container, which can be closed by the compression element, can be placed fairly close to the driver's cab, whereby an optimally large capacity for the garbage collection container is achieved for a given vehicle length.

Es ist zwar aus der DE-OS 28 38 440 bekannt, bei einem Spezialmüllsammelfahrzeug einer anderen Art das Schubelement getrennt vom Müllsammelbehälter und zwar hinten unten bei der Hinterachse des Fahrzeuges anzubringen; jedoch muß zum Befüllen und Verdichten der Müllsammelbehälters hinter dem Fahrzeug auf dem Boden abgesetzt werden, und nimmt auch das Verdichtungselement selbst in seiner Befüll-Endstellung nich einen beträchtlichen Teil des nutzbaren Innenraums des Müllsammelbehälters weg, weil es bauartbedingt nicht bis in die Öffnung des Müllsammelbehälters verfahrbar ist.It is known from DE-OS 28 38 440 to mount the thrust element separately from the refuse collection container in a special waste collection vehicle of a different type, namely at the bottom rear of the vehicle's rear axle; however, to fill and compact the garbage can behind the vehicle on the floor be discontinued, and even the compaction element itself in its filling end position does not take away a considerable part of the usable interior of the refuse collection container because, due to its design, it cannot be moved into the opening of the refuse collection container.

Eine zweckmäßige Ausführungsform geht aus Anspruch 2 hervor. Bei dieser Ausbildung hat der Müllsammelbehälter in gefülltem Zustand eine reine Lager- und Transportfunktion für den Müll, was für moderne Entsorgungsverfahren mit Zwischenlagerung zweckmäßig ist, weil der Müllsammelbehälter leicht, preiswert herstellbar und problemlos lager- und transportfähig ist. Alle für die etwaige Verdichtung des Mülls benötigten Komponenten verbleiben auf dem Fahrgestell des Müllsammelfahrzeuges, wobei sie auf dem Fahrgestell nur wenig Platz beanspruchen.An expedient embodiment emerges from claim 2. With this design, the refuse collection container has a pure storage and transport function for the refuse in the filled state, which is expedient for modern disposal methods with intermediate storage, because the refuse collection container is light, inexpensive to produce and can be easily stored and transported. All components required for the possible compaction of the garbage remain on the chassis of the refuse collection vehicle, whereby they take up little space on the chassis.

Eine weitere zweckmäßige Ausführungsform geht aus Anspruch 3 hervor. Mit dem Kolben läßt sich - falls nötig, der Müll im Müllsammelbehälter wirksam verdichten. Da der Kolben an der Verdichtungsvorrichtung verschiebbar geführt ist, wird der Müllsammelbehälter weitgehend von Führungsaufgaben entlastet, was seiner einfachen Ausbildung förderlich ist.Another useful embodiment is set out in claim 3. If necessary, the piston can effectively compact the waste in the waste collection container. Since the piston is displaceably guided on the compacting device, the refuse collection container is largely relieved of management tasks, which is conducive to its simple design.

Günstig ist ferner die Ausführungsform von Anspruch 4, da der getrennte Verschluß beim Abnehmen des gefüllten Müllsammelbehälters die Öffnung verschließt, so daß hier kein Müll unkontrolliert austreten kann. Der getrennte Verschluß ist auch für die Zwischenlagerung vorteilhaft. Wird Sondermüll oder hochwertiger Müll gesammelt, der nicht verdichtet werden darf, so kann die Öffnung von vornherein durch den getrennten Verschluß verschlossen bleiben, so daß das Verdichtungselement überhaupt nicht zur Wirkung kommt.The embodiment of claim 4 is also advantageous since the separate closure closes the opening when the filled refuse collection container is removed, so that no refuse can escape uncontrolled here. The separate closure is also advantageous for temporary storage. If special waste or high-quality waste is collected, which must not be compacted, the opening can be closed from the start by the separate closure, so that the compacting element does not come into effect at all.

Eine besonders einfache und zweckmäßige Ausführungsform geht ferner aus Anspruch 5 hervor. Hierbei funktionieren die Zinken, Zungen oder Klappen als selbsttätiger Verschluß der Öffnung, sobald das Verdichtungselement in seine Endstellung gebracht bzw. der Müllsammelbehälter vom Fahrgestell abgenommen wird. Beim Arbeiten des Verdichtungselementes öffnen diese Schließelemente die Öffnung selbsttätig.A particularly simple and expedient embodiment is also apparent from claim 5. Here, the tines, tongues or flaps function as an automatic closure of the opening as soon as the compression element is brought into its end position or the waste collection container is removed from the chassis. When the compression element is working, these closing elements open the opening automatically.

Eine andere, vorteilhafte Ausführungsform geht aus Anspruch 6 hervor. Die die Öffnung verschließende Platte, die am Müllsammelbehälter auch bei seiner Zwischenlagerung verbleibt, ist ein baulich von der Verdichtungsvorrichtung getrennter Teil, der nur dann zur Verdichtung einsetzbar ist, wenn der Müll tatsächlich verdichtet werden soll.Another advantageous embodiment is set out in claim 6. The plate closing the opening, which remains on the garbage collection container even when it is temporarily stored, is a part that is structurally separate from the compaction device and can only be used for compaction if the garbage is actually to be compacted.

Zweckmäßig sind dabei die Maßnahmen von Anspruch 7, da die lösbare Kupplung zum Abnehmen des gefüllten Müllsammelbehälters eine rasche Trennung zwischen der Verdichtunsvorrichtung und der Klappe ermöglicht.The measures of claim 7 are expedient, since the detachable coupling for removing the filled refuse collection container enables a rapid separation between the compression device and the flap.

Zweckmäßig sind ferner die Maßnahmen von Anspruch 8, weil diese Ausbildung der Wand des Müllsammelbehälters dem eingefüllten Müll eine den Innenraum des Müllsammelbehälters wirksam füllende Bewegungskomponente aufzwingt, die noch durch das Arbeiten der Klappe unterstützt wird.The measures of claim 8 are also expedient because this design of the wall of the refuse collection container forces the filled refuse into a movement component that effectively fills the interior of the refuse collection container, which is still supported by the working of the flap.

Günstig ist dabei auch die Ausführungsform von Anspruch 9, da die Kolbenstange leicht mit dem Verdichtungselement gekoppelt werden kann und dank ihrer gelenkigen Ankopplung Verspannungen vom Schubelement fernhält.The embodiment of claim 9 is also favorable, since the piston rod can be easily coupled to the compression element and, thanks to its articulated coupling, keeps tension away from the thrust element.

Dabei ist es auch günstig, gemäß Anspruch 10 vorzugehen, weil auf diese Weise der Arbeitszylinder von Querkräften freigehalten bleibt.It is also advantageous to proceed according to claim 10, because in this way the working cylinder is kept free from transverse forces.

Vorteilhaft ist ferner das Merkmal von Anspruch 11, weil durch diese Anordnung die Hebeeinrichtung mit günstigen Hebelarmen und einem optimal kurzen Transportweg für den Müllbehälter zu Einfüllöffnung arbeitet.The feature of claim 11 is also advantageous because, through this arrangement, the lifting device works with favorable lever arms and an optimally short transport route for the refuse container to the filling opening.

Zweckmäßig ist ferner die Ausführungsform von Anspruch 12, weil die konkav gekrümmte Führungsfläche mit der Klappe so zusammenarbeitet, daß praktisch kein Müll durch die Öffnung nach außen gelangen kann.The embodiment of claim 12 is also expedient because the concavely curved guide surface cooperates with the flap in such a way that practically no waste can get out through the opening.

Die Merkmale des Anspruchs 13 sind besonders wichtig, um das Auslaufen von sich aus dem Müll absetzenden Flüssigkeiten aus der Öffnung zu verhindern und so das Fahrgestell oder den jeweiligen Standplatz des Müllsammelbehälters sauberzuhalten.The features of claim 13 are particularly important in order to prevent leakage of liquids settling out of the garbage out of the opening and thus to keep the chassis or the respective location of the garbage collection container clean.

Wichtig ist auch der Gedanke von Anspruch 14, weil für Sondermüll oder hochwertigen Müll, der nicht verdichtet werden dart, beim Arbeiten des Müllsammelfahrzeugs das Verdichtungselement außer Funktion gebracht werden muß.The idea of claim 14 is also important because, for special waste or high-quality waste that does not have to be compacted, the compacting element must be deactivated when the refuse collection vehicle is working.

Im Hinblick auf die Herstellungskosten und Betriebskosten des Müllsammelfahrzeugs ist ferner das Merkmal von Anspruch 15 wesentlich. Serienmäßige Frontlenker-Fahrgestelle sind mit kurzen Lieferzeiten und für die Hälfte der Kosten von Spezial-Fahrgestellen zu erhalten.With regard to the production costs and operating costs of the refuse collection vehicle, the feature of claim 15 is also essential. Standard front-link chassis are available with short delivery times and at half the cost of special chassis.

Ein Müllsammelfahrzeug 1 besteht nach den Fig. 1 und 2 aus einem Fahrgestell 2, zweckmäßigerweise einem serienmäßigen Frontlenkerfahrgestell, das auf einem Fahrgestellrahmen 4 ein Fahrerhaus 3 sowie in einem Abstand hinter diesem einen Müllsammelbehälter 5 trägt. Der Müllsammelbehälter 5 ist zweckmäßigerweise auf dem Fahrgestellrahmen 4 abnehmbar befestigt, um zur weitern Entsorgung bzw. Zwischenlagerung für ein Recycling des gesammelten Mülls getrennt vom eigentlichen Sammelvorgang transportierbar oder lagerfähig zu sein.A garbage collection vehicle 1 according to FIGS. 1 and 2 consists of a chassis 2, expediently a standard front-link chassis which carries a cab 3 on a chassis frame 4 and a garbage collection container 5 at a distance behind it. The waste collection container 5 is expediently attached to the chassis frame 4 so that it can be transported or stored separately from the actual collection process for further disposal or intermediate storage for recycling the collected waste.

Zwischen dem Müllsammelbehälter 5 und dem Fahrerhaus 3 ist auf dem Fahrgestellrahmen 4 ein Traggestell 6 angebracht.A support frame 6 is attached to the chassis frame 4 between the waste collection container 5 and the driver's cab 3.

An der in Fahrtrichtung linken Seite nahe einer dem Fahrerhaus zugewandten Stirnwand 27 des Müllsammelbehälters 5 ist oben eine Einfüllöffnung 7 vorgesehen, die zum Innenraum des Müllsammelbehälters 5 führt und in die in Fig. 2 strichpunktiert angedeutete Müllbehälter 26 entleert werden können. In der Wand 27 ist in einem untenliegenden Bereich eine Öffnung 8 zum Inneraum des Müllsammelbehälters 5 ausgespart, der bei der Ausführungsform der Fig. 1 ein getrennter Verschlußdeckel 9 so zugeordnet ist, daß er fallweise zum Verschließen der Öffnung 8 eingesetzt werden kann.On the left side in the direction of travel near an end wall 27 of the Garbage collection container 5, a filling opening 7 is provided at the top, which leads to the interior of the garbage collection container 5 and can be emptied into the garbage container 26 indicated by dash-dotted lines in FIG. 2. In the wall 27, an opening 8 to the interior of the refuse collection container 5 is recessed in a region below, which in the embodiment of FIG. 1 is assigned a separate closure cover 9 so that it can be used to close the opening 8 in some cases.

Denkbar ist es auch, an zumindest einem Öffnungsrand der Öffnung 9 an Scharnieren 32 Zinken, Zungen oder Klappen 9′ anzulenken, die selbsttätig die Öffnung 8 verschließen und unter einer von außen in Richtung zum Innenraum gerichteten Kraft, z.B. gegen Federbelastung, geöffnet werden können. Der untere Rand der Öffnung 8 kann zur Bildung einer Überlaufschwelle hochgezogen sein. Denkbar ist ferner, den Müllsammelbehälter 5 alternativ auf dem Farhgestell 2 so gekippt zu halten, daß Flüssigkeiten im Müllsammelbehälter 5 aus der Öffnung 8 nicht austreten können.It is also conceivable to link at least one opening edge of the opening 9 to hinges 32 prongs, tongues or flaps 9 'which automatically close the opening 8 and under a force directed from the outside towards the interior, e.g. against spring loading, can be opened. The lower edge of the opening 8 can be raised to form an overflow threshold. It is also conceivable, alternatively, to keep the waste collection container 5 tilted on the frame 2 in such a way that liquids in the waste collection container 5 cannot escape from the opening 8.

Am in Fahrtrichtung hintenliegenden Ende des Müllsammelbehälters 5 ist eine übliche Heck-Entladeklappe 10 an einem obenliegenden Scharnier 11 angelenkt.At the rear end of the waste collection container 5 in the direction of travel, a conventional rear unloading flap 10 is articulated on an overhead hinge 11.

Im Traggerüst 6 ist benachbart zur Wand 27 des Müllsammelbehälters 5 eine Hebeeinrichtung 12 mit einer Müllsammelbehälter-Greifeinrichtung 13 angebracht, mit der die einzeln stehenden Müllsammelbehälter 26 ergriffen, angehoben und in der in Fig. 2 angedeuteten Weise in die Einfüllöffnung 7 entleert werden können.In the support frame 6, a lifting device 12 with a waste collection container gripping device 13 is attached adjacent to the wall 27 of the waste collection container 5, with which the individually standing waste collection container 26 can be gripped, raised and emptied into the filling opening 7 in the manner indicated in FIG. 2.

Ferner ist im Traggerüst 6 eine Verdichtungsvorrichtung 14 vorgesehen, die als Antrieb eines kolbenartigen Verdichtungselementes V, hier eines Kolbens 15, dient, das zwischen der in ausgezogenen Linien gezeigten Endstellung, in der es die Öffnung 8 gerade noch verschließt oder unmittelbar vor dieser steht, und einer in strichpunktierten Linien angedeuteten Verdichtungsstellung bewegbar ist, in der das Verdichtungselement im Innenraum des Müllsammelbehälters 5 liegt und den durch die Einfüllöffnung 7 eingefüllten Müll in Richtung zur Heckentladeklappe 10 fördert, bzw. bei zunehmender Füllung des Innenraums verdichtet. Das Verdichtungselement V kann entweder im Traggerüst 6 oder in der Verdichtungsvorrichtung 14 und gegebenenfalls auch in der Öffnung 8 bzw. im Inneren des Müllsammelbehälters 5 geführt werden. Das Verdichtungselement V, bzw. der Kolben 15 ist mit einem Schubelement 16 der Verdichtungsvorrichtung 15 gekoppelt, das ein doppeltwirkender Hydraulik-Arbeitszylinder ist, der mit seiner Kolbenstange 19 über einen Steckzapfen 20 an einem Lagerbock 21 des Kolbens 15 angreift. Das andere Ende des Zylinders 16 ist bei 18 schwenkbar im Traggerüst 6 abgestützt. In strichlierten Linien 17 ist eine Halterung für den Zylinder 16 im Traggerüst 6 angedeutet. Der Kolben 15 ist mit in seiner Bewegungsrichtung verlaufenden Schürzen 22 versehen, die verhindern, daß der eingefüllte Müll bei der Bewegung des Kolbens in die Verdichtungsstellung hinter den Kolben gelangt und beim Herausziehen des Kolbens mit nach außen gefördert wird.Furthermore, a compression device 14 is provided in the support frame 6, which acts as a piston-like drive Compression element V, here a piston 15, serves to move between the end position shown in solid lines, in which it just closes the opening 8 or is immediately in front of it, and a compression position, indicated by dash-dotted lines, in which the compression element is in the interior of the garbage collection container 5 is located and promotes the garbage filled through the filling opening 7 in the direction of the rear unloading flap 10, or compresses with increasing filling of the interior. The compacting element V can be guided either in the supporting frame 6 or in the compacting device 14 and, if appropriate, also in the opening 8 or in the interior of the refuse collection container 5. The compression element V or the piston 15 is coupled to a thrust element 16 of the compression device 15, which is a double-acting hydraulic working cylinder which engages with its piston rod 19 on a bearing block 21 of the piston 15 via a plug pin 20. The other end of the cylinder 16 is pivotally supported in the supporting structure 6 at 18. A holder for the cylinder 16 in the supporting frame 6 is indicated in dashed lines 17. The piston 15 is provided with aprons 22 running in its direction of movement, which prevent the filled garbage from getting into the compression position behind the piston when the piston is moving and being conveyed to the outside when the piston is pulled out.

Die mit 23 bezeichnete Stirnseite des Kolbens 15 ist als Platte ausgebildet (Fig. 2), die seitliche Ausnehmungen 24 zur Zusammenarbeit mit in Fig. 2 angedeuteten Führungen besitzt.The end face of the piston 15, designated 23, is designed as a plate (FIG. 2), which has lateral recesses 24 for cooperation with guides indicated in FIG. 2.

Das Müllsammelfahrzeug 1 gemäß den Fig. 1 und 2 wird wie folgt betrieben:
Der leere Müllsammelbehälter 5 wird auf den Fahrgestellrahmen 4 aufgesetzt und darauf festgelegt. Seine Öffnung 8 ist dann auf den in der Endstellung stehenden Kolben 15 ausgerichtet. Der Verschluß 9 wird geöffnet. Damit ist das Müllsammelfahrzeug betriebsbereit. Mit der Hebeeinrichtung 12 werden die einzelnen Müllbehälter 26 ergriffen und in die Einfüllöffnung 7 entleert. Der Müll sammelt sich am Boden des Müllsammelbehälters und beginnt dessen Innenraum allmählich zu füllen. Sobald dies für erforderlich gehalten wird, und für den Fall, daß der gesammelte Müll überhaupt verdichtet werden soll, wird der Zylinder 16 beaufschlagt, so daß der Kolben 15 bis in seine Verdichtungsstellung fährt und dabei den Müll in Richtung zur Heckentladeklappe 10 fördert und bei zunehmender Füllung zu verdichten beginnt. Dazu wird der Kolben 15 mehrfach hin- und hergefahren. Sobald der Müllsammelbehälter 5 voll und der darin enthaltene Müll ausreichend verdichtet ist, fährt das Müllsammelfahrzeug zu einer Entladestelle, an der entweder der Müllsammelbehälter 5 durch Kippen über die Heckentladeklappe 10 direkt entladen oder abgenommen und getrennt vom Fahrgestell 2 gelagert oder Weitertransportiert wird. Zuvor ist es allerdings erforderlich, bei in der Endstellung stehendem Kolben 15, den Verschluß 9 vor die Öffnung 8 zu setzen. Sofern die Zinken, Zungen oder Klappen 9′ vorgesehen sind, nehmen diese beim Bewegen des Kolbens 15 in die Endstellung ohnedies ihre Schließstellung ein, in der verhindert wird, daß der Müll aus der Öffnung 8 selbsttätig herausfällt. Der gefüllte Müllsammelbehälter 5 wird nach Abnahme durch einen neuen, gleichartigen und leeren Müllsammelbehälter 5 ersetzt, worauf das Müllsammelfahrzeug 1 wieder betriebsbereit ist.The refuse collection vehicle 1 according to FIGS. 1 and 2 is operated as follows:
The empty waste collection container 5 is placed on the chassis frame 4 and fixed thereon. Its opening 8 is then aligned with the piston 15 in the end position. The shutter 9 is opened. The refuse collection vehicle is now ready for operation. The individual waste containers 26 are gripped with the lifting device 12 and emptied into the filling opening 7. The garbage collects on the bottom of the garbage collection container and begins to fill its interior gradually. As soon as this is considered necessary, and in the event that the collected garbage is to be compressed at all, the cylinder 16 is acted on, so that the piston 15 moves to its compression position and thereby promotes the garbage towards the rear unloading flap 10 and with increasing Filling begins to compact. For this purpose, the piston 15 is moved back and forth several times. As soon as the garbage collection container 5 is full and the garbage contained therein is sufficiently compacted, the garbage collection vehicle travels to an unloading point, at which either the garbage collection container 5 is directly unloaded by tilting via the rear unloading flap 10 or removed and stored separately from the chassis 2 or transported further. Before this, however, it is necessary to place the closure 9 in front of the opening 8 when the piston 15 is in the end position. If the prongs, tongues or flaps 9 'are provided, these take their closed position anyway when the piston 15 is moved into the end position, in which the garbage is prevented from falling out of the opening 8 automatically. The filled garbage collection container 5 is replaced after acceptance by a new, identical and empty garbage collection container 5, whereupon the garbage collection vehicle 1 is ready for operation again.

Das Müllsammelfahrzeug 1′ der Fig. 3 und 4 unterscheidet sich von dem vorbeschriebenen dadurch, daß die Wand 27 des Müllsammelbehälters 5′ in ihrem oberen Teil 29 als schräg nach unten ins Innere des Müllsammelbehälters 5 verlaufende Rutschfläche für den durch die obenliegende Mülleinfüllöffnung 7 zugeführten Müll ausgebildet ist. Knapp unterhalb der Hälfte der Höhe der Wand 27 ist an der Rutschfläche 29 eine Querachse 30 angeordnet, an der eine nach unten hängende Klappe 28 schwenkbar gelagert ist. Die Klappe 28 ist das Verdichtungselement, das in beiden Stellungen, d.h. sowohl in der Endstellung als auch in der Verdichtungsstellung, die Öffnung 8′ in der Wand 27 verschließt. Das Schubelement 16 ist mit seiner Kolbenstange 19 mittels des Steckzapfens 20 über den Lagerbock 21 mit der Klappe 28 verbunden, so daß diese beim Aus- und Einfahren der Kolbenstange 19 eine hinund herschwenkende Bewegung auführt, durch die der eingefüllte Müll zur Heckentladeklappe 10 gefördert und auch verdichtet wird. In der Verdichtungsstellung steht die Klappe 28 in etwa in Verlängerung der Rutschfläche 29, was das Befüllen des Innenraums des Müllsammelbehälters 5′ begünstigt. Dem unteren Rand der Klappe 28 ist eine konkav gekrümmte Führungsfläche 31 zugeordnet, deren Krümmungsachse mit der Achse 30 zusammenfällt. Die Führungsfläche 31 verhindert, daß Müll bei der Bewegung der Klappe 28 nach außen gelangen kann.The refuse collection vehicle 1 'of FIGS. 3 and 4 differs from the one described above in that the wall 27 of the refuse collection container 5' in its upper part 29 as a sloping surface into the inside of the refuse collection container 5, a sliding surface for the refuse fed through the overhead refuse opening 7 is trained. Just below half the height of the wall 27, a transverse axis 30 is arranged on the sliding surface 29, on which a flap 28 hanging downward is pivotably mounted. The flap 28 is the compression element, which in both positions, i.e. both in the end position and in the compression position, the opening 8 'in the wall 27 closes. The thrust element 16 is connected to its piston rod 19 by means of the plug pin 20 via the bearing block 21 with the flap 28, so that when the piston rod 19 is extended and retracted, it performs a back-and-forth movement, through which the filled refuse is conveyed to the rear unloading flap 10 and also is compressed. In the compression position, the flap 28 is approximately in the extension of the sliding surface 29, which favors the filling of the interior of the waste collection container 5 '. A concave curved guide surface 31 is assigned to the lower edge of the flap 28, the axis of curvature of which coincides with the axis 30. The guide surface 31 prevents garbage from escaping when the flap 28 moves.

Das Müllsammelfahrzeug 1′ wird ähnlich betrieben, wie das Müllsammelfahrzeug 1 der Fig. 1 und 2. Unterschiedlich ist nur, daß die Verdichtung und Förderung des Mülls im Inneren des Müllsammelbehälters 5′durch eine schwenkende Bewegung der Klappe 28 erzeugt wird und daß diese Klappe 28 am Müllsammelbehälter 5′ bleibt, wenn dieser im gefüllten Zustand zwischengelagert oder vom Müllsammelfahrzeug getrennt abtransportiet wird.The garbage collection vehicle 1 'is operated similarly to the garbage collection vehicle 1 of Figs. 1 and 2. The only difference is that the compression and conveyance of the garbage inside the garbage collection container 5' is generated by a pivoting movement of the flap 28 and that this flap 28th on the garbage collection container 5 'remains when it is temporarily stored in the filled state or separated from the garbage collection vehicle is transported away.

Es braucht jedoch dazu wiederum nur der Kupplungsstift 20 entfernt zu werden. Aufgrund der Schwenkbewegung der Klappe 28 ist das Schubelement 16 auf- und abschwenkbar gelagert, damit es von Querkräften freigestellt bleibt.However, only the coupling pin 20 needs to be removed. Due to the pivoting movement of the flap 28, the thrust element 16 is mounted so that it can be swiveled up and down so that it remains free from transverse forces.

Alternativ dazu könnte auch eine selbsttätige, lösbare Kupplung zwischen der Kolbenstange 19 und der Klappe 28 oder dem Kolben 15 vorgesehen sein. Ferner könnten in Fahrzeugrichtung zwei oder mehrere nebeneinanderliegende Schubelement vorgesehen sein.Alternatively, an automatic, releasable clutch could also be provided between the piston rod 19 and the flap 28 or the piston 15. Furthermore, two or more thrust elements lying side by side could be provided in the vehicle direction.

Das Schubelement 16 ist zweckmäßigerweise an eine nichtgezeigte Steuervorrichtung angeschlossen, die vom Fahrerhaus aus betätigt wird. Beim Sammeln von Sondermüll, der nicht verdichtet werden darf, bleibt die Klappe 28 in ihrer linken Endstellung, so daß das gesamte Volumen des Müllsammelbehälters 5 ohne Verdichtung des Mülls befüllt werden kann. Es ist ferner denkbar, daß auf den Fahrgestellrahmen 4 verschiedenartig gestaltete Müllsammelbehälter aufgesetzt werden, die jeweils mit der Verdichtungvorrichtung 14 kompatibel sind. Gegebenenfalls ist es jedoch dann erforderlich, die Hebevorrichtung 12 an unterschiedliche Positionen der Einfüllöffnung 7 anpaßbar auszulegen.The thrust element 16 is expediently connected to a control device, not shown, which is actuated from the driver's cab. When collecting special waste that must not be compressed, the flap 28 remains in its left end position so that the entire volume of the waste collection container 5 can be filled without compressing the waste. It is also conceivable that differently designed refuse collection bins are placed on the chassis frame 4, each of which is compatible with the compacting device 14. However, it may then be necessary to design the lifting device 12 to be adaptable to different positions of the filling opening 7.
