Abstract

Es wird eine mobile Arbeitsmaschine, insbesondere Radlader, Teleskoplader, Bagger, Traktor oder dergleichen, mit einem Fahrzeugrahmen und mit einer Antriebseinheit zum Antreiben wenigstens eines Antriebselementes, z.B. eines Antriebsrades und/oder Kettenfahrwerkes, wobei wenigstens eine Werkzeughaltevorrichtung zum Halten eines lösbar verbindbaren Arbeitswerkzeugs vorgesehen ist, wobei die Werkzeughaltevorrichtung wenigstens eine Verriegelungseinheit (21) zum lösbaren Verriegeln des Arbeitswerkzeugs und wenigstens eine Energieübertragungseinheit (18, 19) zum Übertragen von Energie für das Arbeitswerkzeug umfasst, wobei die Verriegelungseinheit (21) wenigstens ein erstes, längs eines ersten Verstellweges zwischen einer Entriegelungsposition und einer Verriegelungsposition verstellbares Riegelelementes (13) aufweist, wobei die Energieübertragungseinheit (18, 19) wenigstens ein erstes, längs eines zweiten Verstellweges zwischen einer Löseposition und einer Übertragungsposition verstellbares Übertragungselementes (19) aufweist, vorgeschlagen, die wenigstens teilweise die Nachteile des Standes der Technik verbessert und insbesondere unter Baustellenbedienungen einen möglichst störungsfreien und/oder vollautomatisierten Betrieb bzw. Werkzeugwechsel, auch über längere Zeit, sicher gewährleisten kann. Dies wird erfindungsgemäß u.a. dadurch erreicht, dass die erste Aufnahmevorrichtung (12, 14) des Arbeitswerkzeugs und/oder die erste Übertragungsvorrichtung (18) des Arbeitswerkzeugs zumindest eine erste Schmutzöffnung (15, 23) und/oder einen ersten Schmutzkanal (15, 23) zum Ausleiten und/oder Durchleiten von Schmutz (22) aufweist.It is a mobile work machine, in particular a wheel loader, telescopic loader, excavator, tractor or the like, with a vehicle frame and with a drive unit for driving at least one drive element, e.g. a drive wheel and / or crawler chassis, with at least one tool holding device being provided for holding a releasably connectable working tool , wherein the tool holding device comprises at least one locking unit (21) for releasably locking the working tool and at least one energy transfer unit (18, 19) for transferring energy for the working tool, the locking unit (21) at least a first, along a first adjustment path between an unlocking position and a locking position adjustable locking element (13), wherein the energy transfer unit (18, 19) at least a first, adjustable along a second adjustment path between a release position and a transfer position it has transmission element (19), which at least partially improves the disadvantages of the state of the art and, in particular, can reliably ensure trouble-free and / or fully automated operation or tool change, even over a longer period of time, under construction site operations. According to the invention, this is achieved, among other things, in that the first receiving device (12, 14) of the work tool and / or the first transmission device (18) of the work tool has at least one first dirt opening (15, 23) and / or a first dirt channel (15, 23) for Has discharge and / or passage of dirt (22).
