Bei einem bekannten Materialaufgabebehälter ist das Rührwerk in zwei behälterfesten Lagern gelagert und wird durch zwei auf der Behälteraußenseite angeordnete Hydraulikmotoren angetrieben. Die Lager und die Motoren sind fest am Materialaufgabebehälter fest montiert. Bei einer Zweizylinder-Dickstoffpumpe verdeckt das Rührwerk im Materialaufgabebehälter die Rohrweiche der Pumpe und einen Teil der Pumpöffnungen. Um an diese Teile beispielsweise zu Wartungszwecken herankommen zu können, muß auch das Rührwerk entfernt werden. Zur Demontage des Rührwerks und der Motoren müssen zunächst die Rührwerksflügel von der Rührwerkswelle entfernt werden, bevor die Achswelle aus den Lagern herausgezogen werden kann. Hierzu müssen Befestigungsschrauben gelöst werden, mit denen die Rührwerksflügel an der Achswelle befestigt sind. Nach längerem Pumpbetrieb sitzen die Schrauben aufgrund von Betonablagerungen meist so fest, daß sie nur mit Hilfe eines Schneidgeräts entfernt werden können.In a known material feed container, the agitator is stored and stored in two container-proof bearings by two hydraulic motors arranged on the outside of the tank driven. The bearings and the motors are firmly attached to the material feed container. At a The two-cylinder thick matter pump conceals the agitator in the material feed container the pipe switch of the pump and one Part of the pump openings. To get to these parts for example To be able to get there for maintenance purposes, that too Agitator be removed. To disassemble the agitator and of the motors must first remove the agitator blades from the Agitator shaft must be removed before the axle shaft is out the bearings can be pulled out. For this, fastening screws be solved with which the agitator blades are attached to the axle shaft. After a long time Pumping the screws sit due to concrete deposits usually so tight that it can only be Cutter can be removed.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, den bekannten Materialaufgabebehälter dahingehend zu verbessern, daß eine leichtere Zugänglichkeit zu den im Behälter befindlichen Bauteilen und Verschleißteilen ermöglicht wird.Proceeding from this, the invention is based on the object the known material feed container to that effect improve that easier accessibility to those in the Components and wearing parts located in the container becomes.

Zur Lösung dieser Aufgabe wird die im Patentanspruch 1 angegebene Merkmalskombination vorgeschlagen.

Gemäß einer bevorzugten Ausgestaltung der Erfindung sind die Drehlager zu diesem Zweck in je einem Lagerblock angeordnet, während die Seitenwände je eine nach oben randoffene Ausnehmung zur flüssigkeitsdichten Aufnahme eines der in ihrer Außenkontur an die Innenkontur der Ausnehmung angepaßten Lagerblöcke aufweisen. Um eine verwindungsfreie Kraftübertragung zwischen den Lagerblöcken und dem Behälterunterteil zu gewährleisten, wird gemäß einer vorteilhaften Ausgestaltung der Erfindung vorgeschlagen, daß die Lagerblöcke unter parallel zu den Seitenwänden ausgerichteter Krafteinleitung formschlüssig mit den Seitenwänden verbindbar sind. Vorteilhafterweise weist die Ausnehmung eine zumindest partiell über die Seitenwand auf der Behälteraußenseite überstehende Randpartie mit einer an die Außenkontur des Lagerblocks angepaßten Innenkontur auf, wobei zwei einander gegenüberliegende Teile der Randpartie mit Durchbrüchen versehen sein können, die miteinander und mit einer im Lagerblock befindlichen Querbohrung fluchten und durch die eine Spannschraube zur Fixierung des Lagerblocks in der Ausnehmung hindurchsteckbar ist. Auf diese Weise ist es möglich, durch Lösen von lediglich zwei Spannschrauben die Rührwerksbaugruppe vom Behälterunterteil abzutrennen, so daß sie beispielsweise mit Hilfe eines Hebezeugs oder eines Krans aus diesem herausgehoben werden kann.According to a preferred embodiment of the invention the pivot bearings are arranged in a bearing block for this purpose, while the side walls each have an open edge Recess for the liquid-tight reception of a the outer contour of the inner contour of the recess have adapted bearing blocks. To a torsion-free Power transmission between the bearing blocks and to ensure the lower part of the container, according to one proposed advantageous embodiment of the invention, that the bearing blocks under parallel to the side walls aligned force transmission with the side walls are connectable. Advantageously, the Recess an at least partially over the side wall overhang on the outside of the container with an inner contour adapted to the outer contour of the bearing block on, with two opposite parts the edge area can be provided with openings, those with each other and with one in the bearing block Align the cross hole and through the one clamping screw Fixing of the bearing block can be pushed through in the recess is. In this way it is possible by loosening the agitator assembly with just two clamping screws detach from the lower part of the container, so that they can be removed, for example with the help of a hoist or a crane from this can be lifted out.

Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht vor, daß die Achswelle an ihren durch die Lager flüssigkeitsdicht hindurchgeführten Enden lösbar mit der Abtriebswelle je eines Motors gekuppelt ist. Die Motoren können dabei mit ihrem Motorgehäuse am benachbarten Lagerblock angeflanscht werden. Um die beim Rühren von Beton auftretenden hohen Drehmomente aufnehmen zu können, weisen die Motoren zweckmäßig eine im wesentlichen radial über das Motorgehäuse überstehende, formschlüssig an der betreffenden Seitenwand verankerbare Drehmomentstütze auf.Another advantageous embodiment of the invention provides that the axle shaft on its through the bearings Removable liquid-tight ends detachable with the Output shaft of one motor is coupled. The motors can with their motor housing on the adjacent bearing block be flanged. To the while stirring concrete to be able to absorb occurring high torques, expediently have the motors essentially radial protruding from the motor housing, positively on the Torque support that can be anchored in the side wall on.

Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung ist ein auf die Oberkante des Behälterunterteils lösbar aufsetzbarer, wahlweise mit dem Behälterunterteil und/oder mit den Lagerhaltern verbindbarer, nach oben und unten offener Behälteraufsatz vorgesehen. Mit dieser Maßnahme kann die Behälterhöhe vergrößert und zugleich erreicht werden, daß der Behälteraufsatz entweder mit oder ohne Rührwerksbaugruppe vom Behälterunterteil beispielsweise zu Reinigungs- und Wartungszwecken abgenommen werden kann.According to a further preferred embodiment of the invention is on the upper edge of the lower part of the container detachably attachable, optionally with the lower part of the container and / or connectable to the storage brackets, upwards and open container attachment provided below.

Zweckmäßig weist hierzu die an der Rückwand des Behälterunterteils überstehende Flanschpartie mindestens zwei randoffene und die über die Stirnwand überstehende Flanschpartie mindestens zwei geschlossene Durchbrüche für den Durchtritt je einer die Flanschpartie des Behälteraufsatzes durchdringenden Flanschschraube auf. Um den Behälteraufsatz gegenüber dem Behälterunterteil verschwenken zu können, sind zumindest die stirnwandseitigen Flanschschrauben am Behälteraufsatz angeflanscht.The bottom part of the container and the top of the container are advantageous at the edge of the front and back wall projecting flange sections can be connected to each other. Appropriately, this points to the rear wall of the lower part of the container protruding flange section at least two open edge and overhanging the front wall Flange section at least two closed openings for the passage of one the flange section of the container attachment penetrating flange screw. To the Swivel the container attachment in relation to the lower part of the container to be able to, are at least the front wall Flange screws flanged to the container attachment.

Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist der Behälteraufsatz über im Bereich seiner Unterkante seitenwandseitig nach außen überstehende Flanschpartien mit je einem der Lagerblöcke lösbar verbindbar. Zu diesem Zweck weist der Behälteraufsatz im Bereich seiner seitenwandseitig überstehenden Flanschpartie mindestens eine mit einer Schraubbohrung des Lagerblocks fluchtende Bohrung für eine Befestigungsschraube auf.According to a further advantageous embodiment of the invention the container attachment is over in the area of its Lower edge on the side wall protruding outwards Flange sections can be releasably connected to one of the bearing blocks. For this purpose, the container attachment points in the area its flange section protruding on the side wall at least one with a screw hole in the bearing block aligned hole for a fastening screw.

Zur flüssigkeitsdichten Abdichtung des Behälters im Bereich der Rührwerkslager ist es von Vorteil, wenn zwischen den in ihrer Kontur aufeinander abgestimmten Trennflächen des Lagerblocks und der Ausnehmung ein umlaufender Dichtring angeordnet ist.
