Description

Der Stand der Technik 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, wie im Dokument WO-A-03/037507 offenbart ist.The prior art relates to a construction machine, in particular a mortar molding machine, with a frame-fixed material funnel, with a about a frame-fixed horizontal tilt axis between a lowered loading and mixing position and a raised discharge position pivotable mixing container and with a about a horizontal pivot axis between a closed position and an open position pivotable relative to a container opening of the mixing container, a Einfüllgitter having hinged lid, wherein between the hinged lid and a bulkhead of the container opening in the emptying position with a filling opening of the material funnel communicating and arranged with the pouring edge in this emptying discharge opening, as in the document WO-A-03/037507 is disclosed.

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 is first mixed in the mixing container with water and thereby processed into a processible wet material. The transfer of the wet material from the mixing container into the material hopper takes place in the case of the reciprocating mixer in that the mixing container is lifted and thereby tilted or rotated. The mixing container also contains a lid, which must be raised for cleaning and maintenance purposes. This cover is arranged in known mortar spraying machines about an axis parallel to the tilting axis of the stroke mixer pivotally mounted on the mixing container. Also on the side of the material funnel usually a grid cover is provided which is intended to prevent Hineinfassen in the agitator located there. During the emptying process, the wet material was previously poured from the mixing container through the grid in the material hopper. This has the disadvantage that the grid is contaminated by curing wet material 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 transferring the dry material into the mixing container and during 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 present invention seeks to improve the known construction machine of the type described in that the mixing container can be emptied without risk of contamination and that remain in the lowered feed position of the mixing container, the transfer openings between the mixing container and the material hopper.

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, the feature combination specified in claim 1 is proposed. Advantageous embodiments and modifications 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 a cover device is arranged between the mixing container and the material funnel, which closes the emptying opening and the filling opening to the outside when the mixing container is lowered and releases the passage between the emptying opening and the filling opening when the mixing container is raised. Further, according to an advantageous embodiment of the invention, it is provided that the cover device closes the emptying opening when the mixing container is lowered and the hinged lid is closed, and releases the emptying opening when the hinged lid is open. To achieve this, it is provided according to a preferred or alternative embodiment of the invention that the tilting axis of the mixing container and the pivot axis of the hinged lid coincide.

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 comprises two cover members, of which a first on the hinged lid of the mixing container at a distance from the bulk edge and a second on Material funnel is articulated at a distance from the hopper facing the mixing container, wherein the cover members are hingedly connected to each other on their sides facing each other on a hinge axis parallel to the two other hinge axes and the pivot axis of the mixing tank joint axis.

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 coupling pieces mounted in pairs on two joint axes and one cover sheet each extending between the pairs of mutually associated coupling pieces.

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 is formed by the rear opening edge of the mixing container and the discharge opening extends between the pouring edge and the rear hinged lid edge arranged at a distance therefrom.

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, which is overlapped by a pivoting grid. Suitably, the pivoting grid is pivotable about a pivot axis relative to the hopper opening, which coincides with the material hopper side hinge axis of the second cover member.

Eine bevorzugte Ausgestaltung der Erfindung sieht vor, dass im Inneren des Klappdeckels im Abstand vom Einfüllgitter und von der Entleerungsöffnung ein mit einer Ansaugöffnung ins Behälterinnere weisendes und mit einer Austrittsöffnung durch eine Deckelwand nach außen geführtes Ventilrohr angeordnet ist, das bei abgesenktem Mischbehälter und geschlossenem Klappdeckel mit Druckluft beaufschlagbar ist. Die Ansaugöffnung ist gemäß der Erfindung also vor allem dann in Betrieb, wenn zugleich die Abdeckvorrichtung zum Materialtrichter hin verschlossen ist.A preferred embodiment of the invention provides that in the interior of the hinged lid at a distance from the filling grid and from the discharge opening with a suction opening into the container interior and with an outlet opening through a top wall outwardly guided valve tube is arranged with the lowered mixing container and closed hinged lid Compressed air can be acted upon. The suction opening is according to the invention, therefore, above all in operation when at the same time the covering is closed to the material hopper.

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, a compressed air pipe arranged inside the lid is connected to the inlet opening of the Venturi tube, which communicates with closed mixing container and hinged lid with a frame-fixed, acted upon with compressed air connection opening and is separated from the connection opening with raised mixing container and / or open hinged lid. In this case, the pressure outlet of a compressed air generator or blower arranged outside the hinged lid, preferably in an engine compartment, can be connected to the connection opening. On the other hand, the outlet opening of the venturi can be connected to a dust trap, in particular a filter element or a liquid bath. In order to bring about a particularly effective dust separation, the venturi expediently has a centrifugal separator for separating dust from the compressed air flow.

Eine Besonderheit der Erfindung besteht darin, dass zwischen dem Mischbehälter 22 und dem Materialtrichter 18 eine Abdeckvorrichtung 44 angeordnet ist, die dafür sorgt, dass die zwischen der Schüttkante 46 des Mischbehälters und der rückwärtigen Kante 48 des Klappdeckels 28 ausgebildete Entleerungsöffnung 50 und die außerhalb des Abdeckgitters 36 im Öffnungsbereich des Materialtrichters 18 angeordnete Einfüllöffnung bei abgesenktem Mischbehälter nach außen abgedeckt ist und bei angehobenem Mischbehälter einen Durchgang zwischen Entleerungsöffnung 50 und Einfüllöffnung 52 freigibt.A special feature of the invention is that between the mixing container 22 and the material hopper 18, a cover 44 is arranged, which ensures that formed between the pouring edge 46 of the mixing container and the rear edge 48 of the hinged lid 28 emptying opening 50 and the outside of the cover grid 36 arranged in the opening region of the material hopper 18 filling opening is covered with lowered mixing container to the outside and with raised mixing container a passage between discharge opening 50 and filling opening 52 releases.

Die Abdeckvorrichtung 44 umfasst zwei Abdeckglieder 54, 56. Das erste Abdeckglied 54 ist dabei am rückwärtigen Ende des Klappdeckels 28 an einem im Abstand von der Schüttkante des Mischbehälters 22 angeordneten Gelenk 58 angelenkt. Das zweite Abdeckglied 56 ist am Materialtrichter 18 im Abstand von der dem Mischbehälter 22 zugewandten Trichterkante 60 an einem Gelenk 62 angelenkt. Außerdem sind die Abdeckglieder 54, 56 an ihren einander zugewandten Seiten an einer zu den beiden anderen Gelenkachsen 58, 62 und zur Kippachse 20 parallele Gelenkachse 64 miteinander verbunden. Wie insbesondere aus Fig. 2a bis 2e und 3a bis 3e zu ersehen ist, weisen die Abdeckglieder 54, 56 jeweils zwei außenseitige, paarweise an jeweils zwei der Gelenkachsen 58, 62, 64 gelagerte Koppelstücke 66, 68 sowie je ein sich zwischen den paarweise einander zugeordneten Koppelstücken 66, 68 erstreckendes Abdeckblech 70, 72 auf.The cover device 44 comprises two cover members 54, 56. The first cover member 54 is hinged at the rear end of the hinged lid 28 at a spaced from the bulk edge of the mixing container 22 joint 58. The second cover member 56 is hinged to the material hopper 18 at a distance from the mixing container 22 facing funnel edge 60 at a hinge 62. In addition, the cover members 54, 56 are connected at their sides facing each other on a to the other two hinge axes 58, 62 and the tilt axis 20 parallel hinge axis 64 with each other. As in particular from Fig. 2a to 2e and 3a to 3e It can be seen, the cover members 54, 56 each have two outside, in pairs on each of the joint axes 58, 62, 64 mounted coupling pieces 66, 68 and each one between the paired mutually associated coupling pieces 66, 68 extending cover plate 70, 72.

Die Kinematik der Abdeckvorrichtung 44 lässt sich besonders gut in den Figuren 2a bis 2e in Verbindung mit Fig. 3a bis 3e erkennen. In der abgesenkten Position des Mischbehälters 22 befinden sich die beiden Abdeckglieder 54, 56 über den zugehörigen Entleerungs- und Einfüllöffnungen 50, 52. In dieser Position sind die beiden Abdeckglieder 54, 56 nur leicht gegeneinander abgewinkelt. Beim Kippen des Mischbehälters 22 um seine Kippachse 20 wird das erste Abdeckglied 54 zunächst angehoben, während das zweite Abdeckglied gegenüber seiner Ausgangsposition abgesenkt wird. Im weiteren Verlauf der Hubbewegung überschreitet das erste Abdeckglied 54 einen Totpunkt (zwischen Fig. 2b und 2c) und wird sodann im weiteren Verlauf zusammen mit dem Abdeckglied 56 in den Materialtrichter 18 abgesenkt. Im letzten Bewegungsabschnitt bleibt das zweite Abdeckglied 56 nahezu in seiner Position stehen, während das erste Abdeckglied 54 weiter in den Materialtrichter hineingeschwenkt wird (Fig. 2e). In dieser Position greift der Mischbehälter mit seiner Schüttkante 46 und mit der rückwärtigen Klappdeckelkante 48 in den Materialtrichter ein, so dass das im Mischbehälter 22 befindliche Mischgut durch die Einfüllöffnung 52 frei in den Materialtrichter 18 übertreten kann. Nach dem Entleerungsvorgang wird der Mischbehälter 22 wieder in entgegengesetzter Richtung abgesenkt. Zu Transportzwecken befindet sich der Mischbehälter zweckmäßig in seiner abgesenkten Position gemäß Fig. 1a.The kinematics of the cover 44 can be particularly well in the figures 2a to 2e in conjunction with Fig. 3a to 3e detect. In the lowered position of the mixing container 22 are the two cover members 54, 56 via the associated emptying and filling openings 50, 52. In this position, the two cover members 54, 56 are only slightly angled against each other. When tilting the mixing container 22 about its tilting axis 20, the first cover member 54 is first raised, while the second Cover member is lowered relative to its initial position. In the further course of the lifting movement, the first cover member 54 exceeds a dead center (between Fig. 2b and 2c ) and is then lowered in the further course together with the cover member 56 into the material hopper 18. In the last movement section, the second cover member 56 remains almost in its position, while the first cover member 54 is further pivoted into the material hopper ( Fig. 2e ). In this position, the mixing container engages with its pouring edge 46 and with the rear hinged lid edge 48 in the material hopper, so that the mix contained in the mixing container 22 can pass freely through the filling opening 52 into the material hopper 18. After the emptying process, the mixing container 22 is lowered again in the opposite direction. For transport purposes, the mixing container is appropriate in accordance with its lowered position Fig. 1a ,
