Description

Die Erfindung betrifft eine Baumaschine, insbesondere eine Mörtelspritzmaschine, mit einem gestellfesten Materialtrichter, mit einem um eine gestellfeste horizontale Kippachse zwischen einer abgesenkten Beschickungs- und Mischposition und einer angehobenen Entleerungsposition verschwenkbaren Mischbehälter und mit einem um eine horizontale Schwenkachse zwischen einer Schließstellung und einer Offenstellung gegenüber einer Behälteröffnung des Mischbehälters verschwenkbaren, ein Einfüllgitter aufweisenden Klappdeckel, wobei zwischen dem Klappdeckel und einer Schüttkante der Behälteröffnung eine in der Entleerungsposition mit einer Einfüllöffnung des Materialtrichters kommunizierende und mit der Schüttkante in diese eintauchende Entleerungsöffnung angeordnet ist.The invention relates to a construction machine, in particular a mortar spraying machine, with a frame-fixed material hopper, with one around a frame-fixed horizontal tilt axis between a lowered feed and Mixed position and a raised emptying position pivotable Mixing container and with a horizontal pivot axis between a closed position and an open position relative to a container opening the mixing container pivotable, having a filling grid Hinged lid, wherein between the hinged lid and a loose edge of the Container opening one in the emptying position with a filling opening of the Material funnel communicating and with the pouring edge in this dipping Emptying opening is arranged.

Eine Besonderheit vieler Maschinen dieser Art besteht darin, dass der pulverförmige Mörtel zunächst in dem Mischbehälter mit Wasser vermischt und dabei zu einem verarbeitbaren Nassmaterial verarbeitet wird. Die Übergabe des Nassmaterials vom Mischbehälter in den Materialtrichter erfolgt im Falle des Hubmischers dadurch, dass der Mischbehälter angehoben und dabei gekippt oder gedreht wird. Der Mischbehälter enthält außerdem einen Deckel, der zu Reinigungs- und Wartungszwecken angehoben werden muss. Dieser Deckel ist bei bekannten Mörtelspritzmaschinen um eine zur Kippachse des Hubmischers parallele Achse schwenkbar am Mischbehälter angeordnet. Auch auf der Seite des Materialtrichters ist üblicherweise eine Gitterabdeckung vorgesehen, die ein Hineinfassen in das dort befindliche Rührwerk verhindern soll. Beim Entleerungsvorgang wurde das Nassmaterial bisher vom Mischbehälter aus durch das Gitter in den Materialtrichter gegossen. Dies hat den Nachteil, dass das Gitter durch Aushärten von Nassmaterial an den Gitterstäben verschmutzt wird. A special feature of many machines of this type is that the powdered Mortar first in the mixing container mixed with water and thereby being processed into a processible wet material. The handover the wet material from the mixing container into the material hopper takes place in the case of the Hubmischers in that the mixing container lifted and thereby is tilted or rotated. The mixing container also contains a lid, which must be raised for cleaning and maintenance purposes. This cover is in known mortar spraying machines to a tilt axis the lift mixer parallel axis pivotally mounted on the mixing container. Also on the side of the material funnel is usually a grid cover provided, which is a fine into the there To prevent agitator. During the emptying process, the wet material became previously poured from the mixing container through the grid in the material hopper. This has the disadvantage that the grid by curing wet material is contaminated on the bars.

Andererseits ist es zweckmäßig, dass beim Einfüllen des Trockenmaterials in den Mischbehälter und beim Mischvorgang die Übergabeöffnungen zwischen Mischbehälter und Materialtrichter verschlossen sind.On the other hand, it is expedient that when filling the dry material in the mixing vessel and the mixing process, the transfer openings between Mixing container and material funnel are closed.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, die bekannte Baumaschine der eingangs angegebenen Art dahingehend zu verbessern, dass der Mischbehälter ohne Verschmutzungsgefahr entleert werden kann und dass in der abgesenkten Beschickungsposition des Mischbehälters die Übergabeöffnungen zwischen dem Mischbehälter und dem Materialtrichter abgedeckt bleiben.Proceeding from this, the invention has the object, the well-known Construction machine of the type specified to improve to that the mixing container can be emptied without risk of contamination and that in the lowered loading position of the mixing container the Transfer openings between the mixing vessel and the material funnel stay covered.

Zur Lösung dieser Aufgabe wird die im Patentanspruch 1 angegebene Merkmalskombination vorgeschlagen. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.To solve this problem is specified in claim 1 feature combination proposed. Advantageous embodiments and Further developments of the invention will become apparent from the dependent claims.

Der erfindungsgemäßen Lösung liegt vor allem der Gedanke zugrunde, dass zwischen Mischbehälter und Materialtrichter eine Abdeckvorrichtung angeordnet ist, die bei abgesenktem Mischbehälter die Entleerungsöffnung und die Einfüllöffnung nach außen verschließt und bei angehobenem Mischbehälter den Durchgang zwischen Entleerungsöffnung und Einfüllöffnung freigibt. Weiter ist gemäß einer vorteilhaften Ausgestaltung der Erfindung vorgesehen, dass die Abdeckvorrichtung bei abgesenktem Mischbehälter und verschlossenem Klappdeckel die Entleerungsöffnung verschließt und bei offenem Klappdeckel die Entleerungsöffnung freigibt. Um dies zu erreichen, ist gemäß einer bevorzugten oder alternativen Ausgestaltung der Erfindung vorgesehen, dass die Kippachse des Mischbehälters und die Schwenkachse des Klappdeckels zusammenfallen.The solution according to the invention is based primarily on the idea that arranged between the mixing container and material funnel a covering is, with lowered mixing container, the discharge opening and closes the filling opening to the outside and with the mixing container raised the passage between emptying opening and filling opening releases. It is further provided according to an advantageous embodiment of the invention, that the cover device with lowered mixing container and closed hinged lid closes the discharge opening and at open hinged lid releases the discharge opening.

Eine bevorzugte Ausgestaltung der Erfindung sieht vor, dass die Abdeckvorrichtung zwei Abdeckglieder umfasst, von denen ein erstes am Klappdeckel des Mischbehälters im Abstand von dessen Schüttkante und ein zweites am Materialtrichter im Abstand von der dem Mischbehälter zugewandten Trichterkante angelenkt ist, wobei die Abdeckglieder an ihren einander zugewandten Seiten an einer zu den beiden anderen Gelenkachsen und zur Schwenkachse des Mischbehälters parallel ausgerichteten Gelenkachse gelenkig miteinander verbunden sind.A preferred embodiment of the invention provides that the covering device comprising two cover members, a first of which on the hinged lid of the mixing container at a distance from the bulk edge and a second at Material funnel at a distance from the hopper edge facing the mixing container is hinged, wherein the cover members at their facing each other Pages at one of the two other joint axes and the pivot axis of the mixing container aligned parallel hinge axis articulated connected to each other.

Bevorzugt weisen die Abdeckglieder zwei paarweise an jeweils zwei Gelenkachsen gelagerte Koppelstücke sowie je ein sich zwischen den paarweise einander zugeordneten Koppelstücken erstreckendes Abdeckblech auf.The cover members preferably have two pairs in each case on two joint axes mounted coupling pieces as well as each one between the pairs on each associated coupling pieces extending cover plate.

Als besonders vorteilhaft hat es sich erwiesen, wenn die Schüttkante durch die rückwärtige Öffnungskante des Mischbehälters gebildet ist und die Entleerungsöffnung sich zwischen der Schüttkante und der im Abstand von dieser angeordneten rückwärtigen Klappdeckelkante erstreckt.It has proved to be particularly advantageous if the pouring edge passes through the rear opening edge of the mixing container is formed and the discharge opening between the pouring edge and the distance from this arranged rear hinged lid edge extends.

Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht vor, dass der Materialtrichter neben der Einfüllöffnung eine Trichteröffnung aufweist, die von einem Schwenkgitter übergriffen ist. Zweckmäßig ist das Schwenkgitter um eine Schwenkachse gegenüber der Trichteröffnung verschwenkbar, die mit der materialtrichterseitigen Gelenkachse des zweiten Abdeckgliedes zusammenfällt.A further advantageous embodiment of the invention provides that the material funnel next to the filling opening has a funnel opening, the of a swivel grid is overlapped. Appropriately, the swivel grid is around a pivot axis with respect to the funnel opening pivoted with the material hopper side hinge axis of the second cover member coincides.

Vorteilhafterweise ist an die Eingangsöffnung des Venturirohrs ein im Deckelinneren angeordnetes Druckluftrohr angeschlossen, das bei geschlossenem Mischbehälter und Klappdeckel mit einer gestellfesten, mit Druckluft beaufschlagten Anschlussöffnung kommuniziert und bei angehobenem Mischbehälter und/oder offenem Klappdeckel von der Anschlussöffnung getrennt ist. An die Anschlussöffnung kann dabei der Druckausgang eines außerhalb des Klappdeckels vorzugsweise in einem Motorraum angeordneten Drucklufterzeugers oder Gebläses angeschlossen sein. Andererseits kann die Austrittsöffnung des Venturirohrs an eine Staubfalle, insbesondere ein Filterelement oder ein Flüssigkeitsbad angeschlossen sein. Um eine besonders wirksame Staubabtrennung herbeiführen zu können, weist das Venturirohr zweckmäßig einen Zentrifugalabscheider zur Abtrennung von Staub aus dem Druckluftstrom auf.Advantageously, at the inlet opening of the Venturi tube inside the lid connected compressed air pipe connected, the closed Mixing container and hinged lid with a frame-fixed, with compressed air acted upon port opening communicates and raised Mixing container and / or open hinged lid separated from the connection opening is.
