Ein Fahrmischer dieser Art ist beispielsweise aus EP 0 374 682 B1 bekannt.A truck mixer of this type is known for example from EP 0 374 682 B1 known.
In zunehmendem Maße werden Fahrmischer zum Transport von flüssigem Mischgut verwendet, so daß es notwendig ist, die hintere Öffnung der Trommel durch einen Deckel zu verschließen, der ein Herausschwappen des flüssigen Mischguts verhindert.Truck mixers are increasingly used to transport liquid Mixed material used so that it is necessary to open the rear opening seal the drum with a lid that spills out of the mixed liquid prevented.
Ein bekanntes übliches Deckelsystem der eingangs angegebenen Art
wird nachstehend anhand der Fig. 5 bis 7 der Zeichnung näher erläutert:
Auf dem nicht dargestellten Fahrzeugrahmen eines Lkw ist um eine
zum Fahrzeugende hin schräg ansteigende Drehachse 1 eine Mischtrommel
2 drehbar gelagert. Die Mischtrommel 2 besitzt an ihrem
hinteren Ende eine kreisrunde Öffnung 3 mit einem sich konusförmig
nach außen hin erweiternden umlaufenden flanschförmigen Rand
4. Der untere Teil des flanschförmigen Randes 4 ist von einem
rahmenfest gehalterten Auslauftrichter 5 eingefaßt. Dieser Auslauftrichter
5 besteht aus zwei im wesentlichen U-förmig gekrümmten,
stumpfwinkelig zueinander angeordneten rinnenförmigen Teilen
6, 7, deren unteren Schenkel in entsprechenden Ausschnitten
den flanschförmigen Rand 4 der Mischtrommel 2 übergreifen. Die
beiden rinnenförmigen Teile 6, 7 des Auslauftrichters sind im
Bereich der vertikalen Mittelebene der Mischtrommel 2 in der Weise
miteinander verschweißt, daß sie eine Auslauföffnung 8 bilden.
Der Auslauftrichter 5 ist durch seitliche Haltestücke 9, 10
und nicht dargestellte zwischengeschaltete Böcke oder Stützen
mit dem Fahrzeugrahmen verbunden.A known common lid system of the type mentioned
is explained in more detail below with reference to FIGS. 5 to 7 of the drawing:
On the vehicle frame of a truck, not shown, is around one
towards the end of the vehicle, the axis of rotation 1 rises obliquely, a mixing
Mit den oberen Seitenteilen des Trichters 8 ist über Haltestücke
12, 13 ein Tragbügel 14 verbunden, an dessen Scheitelbereich
durch ein Gelenk 15 über ein Tragstück 16 ein kreisrunder Verschluß
17 angelenkt ist. Mit dem Deckel 17 ist ein diesen durchsetzender
Einlauftrichter 18 verbunden. Zum Verschwenken des
Deckels 17 ist eine Druckmittel-Kolben-Zylinder-Einheit 19 vorgesehen,
deren Zylinder mittig an einem dreieckigen Blech 20
angelenkt ist, das mit den äußeren Schenkeln der Seitenteile 6,
7 des Auslauftrichters verschweißt ist, und dessen Kolbenstange
an dem mittleren oberen Bereich des Einfülltrichters 18 angelenkt
ist.With the upper side parts of the
In Fig. 6 ist der Deckel 17 in seiner Verschlußstellung dargestellt,
in der die Deckeldichtung schleifenden an dem flanschförmigen Rand 4 der
Mischtrommel anliegt.6, the
Aus Fig. 5 ist die Öffnungsstellung des Deckels 17 ersichtlich, in der dieser den
Auslauftrichter 5 freigibt. In dieser Öffnungsstellung stößt der Deckel 17 mit seinem
unteren Randbereich an die äußere Begrenzungswandung des Auslauftrichters 5
an, so daß der Öffnungswinkel a 1 des Deckels 17 begrenzt ist.From Fig. 5, the open position of the
Insbesondere zum Zweck der Reinigung der Mischtrommel, des Deckelsystems und der Dichtung und des Mischtrommelrandes ist ein guter und einfacher Zugang zu dem Öffnungsbereich der Mischtrommel erwünscht, der jedoch bei den bekannten Fahrmischem behindert wird, daß der Öffnungswinkel a 1 des Deckels durch das Anstoßen an die äußere Wandung des Auslauftrichters stark eingeschränkt ist.Especially for the purpose of cleaning the mixing drum, the lid system and the seal and mixing drum rim is a good and easy access desired to the opening area of the mixing drum, but that in the known Truck mixer is hindered that the opening angle a 1 of the cover severely restricted by hitting the outer wall of the discharge funnel is.
Aus der US 2,267,801 ist ein Betonmischer bekannt, bei dem der Auslauftrichter so weit ausgeschnitten ist, daß der Deckel über die äußere Wandung des Auslauftrichters hinaus aufgeschwenkt werden kann. Verbesserungsfähig bei diesem bekannten Fahrmischer ist jedoch das Ausgußverhalten, insbesondere besteht die Gefahr, daß beim Ausgießen der Beton überschwappt und neben den Auslauftrichter schwappt.From US 2,267,801 a concrete mixer is known in which the discharge funnel is so is cut far out that the lid over the outer wall of the discharge funnel can be swung open. Can be improved on this well-known However, the mixer is the pouring behavior, in particular there is Danger of the concrete spilling out when pouring and next to the discharge funnel slops.
Aus der US 4,318,621 ist ein fahrbarer Betonmischer bekannt, bei dem der Einlauftrichter ebenfalls verschwenkbar ist, und zwar derart, daß er in der Einfüllstellung mit seinem Ausgußende in die Mischertrommel ragt. Der Schwenkmechanismus ist derart gestaltet, daß dennoch der Einlauftrichter beim Schwenken nicht mit der Trommel und den darin angeordneten Mischerblättern kollidiert.From US 4,318,621 a mobile concrete mixer is known in which the inlet funnel is also pivotable, in such a way that it is in the filling position protrudes into the mixer drum with its pouring end. The swivel mechanism is designed in such a way that the inlet funnel does not move with the Drum and the mixer blades arranged in it collided.
Aus der US 2,451,555 ist ein fahrbarer Betonmischer bekannt, bei dem der Einlauftrichter geradlinig von der Ausgußöffnung der Mischertrommel weg und auf diese zu bewegt werden kann. Der für eine derartige Bewegung des Einlauftrichters notwendige Bewegungsmechanismus ist jedoch relativ kompliziert. From US 2,451,555 a mobile concrete mixer is known in which the inlet funnel straight away from the pouring opening of the mixer drum and onto it too can be moved. The one necessary for such a movement of the inlet funnel Movement mechanism, however, is relatively complicated.
Der Erfindung liegt daher die Aufgabe zugrunde, einen verbesserten Fahrmischer der eingangs genannten Art zu schaffen, der einen sicheren Ausguß des Mischgutes erlaubt und gleichzeitig in einfacher Weise einen Zugang zu der Öffnung der Mischtrommel zu Wartungs- und Reinigungszwecken ermöglicht.The invention is therefore based on the object of an improved truck mixer of the type mentioned to create a safe pouring of the mix allowed and at the same time easy access to the opening of the Mixing drum enabled for maintenance and cleaning purposes.
Diese Aufgabe wird durch einen Fahrmischer gemäß Patentanspruch 1 gelöst. Bevorzugte Ausgestaltungen sind Gegenstand der weiteren Ansprüche.This object is achieved by a truck mixer according to claim 1. preferred Refinements are the subject of the further claims.
Der Auslauftrichter ist also mit einem der Kontur des unteren Bereiches des Deckelrandes entsprechenden runden Ausschnitt versehen, der ein Ausschwenken des Deckels über den Auslauftrichter hinaus gestattet. Bei dem erfindungsgemäßen Fahrmischer ist also der Öffnungswinkel des Deckels nicht durch die äußere Wandung des Auslauftrichters beschränkt, da der Deckel über diesen hinaus geschwenkt werden kann. Wird die den Deckel verschwenkende Druckmittel-Kolben-Zylinder-Einheit gelöst oder ausgehakt, läßt sich dieser sogar bis auf die Mischtrommel zurückklappen, so daß die Öffnung der Mischtrommel völlig freigegeben wird.The outlet funnel is therefore with one of the contours of the lower region of the lid edge appropriate round cutout provided that the pivoting of the Lid allowed beyond the outlet funnel. In the inventive The mixer is not the opening angle of the lid through the outer wall of the discharge funnel because the lid is pivoted beyond this can be. Will the pressure-piston-cylinder unit pivoting the cover loosened or unhooked, it can even be moved down to the mixing drum fold back so that the opening of the mixing drum is fully released.
Zweckmäßigerweise ist die Krümmung des Ausschnitts des Auslauftrichters derart an die Krümmung des Deckels angepaßt, daß der Deckel bei seinem Verschwenken den Rand des Ausschnitts gerade passieren kann. Diese Ausgestaltung sieht somit vor, daß zwischen dem etwa in den Bereich der äußeren Wandung des Auslauftrichters geschwenkten Deckel und dem Ausschnitt nur ein schmaler Spalt verbleibt, so daß während des Entleervorgangs der Dekkel den Auslauftrichter nach außen hin abschließt und ein unerwünschtes Austreten von Mischgut über den Rand des Auslauftrichters verhindert. Ein nahezu vollständiger Abschluß wird erreicht, wenn sich in der Entleerstellung der entsprechend teilweise ausgeschwenkte Deckel in der Ebene der äußeren Wandung des Auslauftrichters befindet.The curvature of the cutout of the discharge funnel is expedient so adapted to the curvature of the lid that the When pivoting, cover the edge of the cutout straight can happen. This configuration therefore provides that between approximately in the area of the outer wall of the discharge funnel pivoted lid and the neckline just a narrow one Gap remains so that the lid is emptied during the emptying process closes the outlet funnel to the outside and an undesirable Mix material escapes over the edge of the discharge funnel prevented. An almost complete conclusion is reached if there is a corresponding partial discharge swung out lid in the plane of the outer wall of the Outlet funnel.
Zweckmäßigerweise ist der Deckel an einem Bügel gelagert, dessen Schenkel mit den äußeren Seitenteilen des Auslauftrichters verbunden sind.The lid is expediently mounted on a bracket, the Leg connected to the outer side parts of the discharge funnel are.
Zum Verschwenken des Deckels können zwei seitliche Druckmittel-Kolben-Zylinder-Einheiten vorgesehen sein. Diese Druckmittel-Kolben-Zylinder-Einheiten sind zweckmäßigerweise jeweils gelenkig mit den Seitenteilen des Auslauftrichters und des Einfülltrichters verbunden.Two side pressure medium piston-cylinder units can be used to pivot the cover be provided. These pressure medium piston-cylinder units are appropriately articulated with the side parts of the discharge funnel and the filling funnel connected.
