Für die Verarbeitung soll Gussasphalt als fließfähige Masse bei einer Temperatur von beispielsweise mehr als 200° C vorliegen. GB 801,111 A discloses a transport container for mastic asphalt. An intensive mixer for concrete components is out DE 2 209 673 A known. Mastic asphalt is produced in a plant. For processing, mastic asphalt should be present as a flowable mass at a temperature of, for example, more than 200 ° C.

Es ist die Aufgabe der vorliegenden Erfindung, den Transport von verarbeitbaren Gussasphalt zu vereinfachen.It is the object of the present invention to facilitate the transport of workable mastic asphalt.

Diese Aufgabe ist erfindungsgemäß gelöst durch eine mobile Arbeitsmaschine mit den im Anspruch 1 angegebenen Merkmalen. Erfindungsgemäß wurde erkannt, dass eine mobile Arbeitsmaschine für den Transport von Gussasphalt, der insbesondere fertig gemischt ist, ein Rührwerk mit einem elektrischen Rührwerks-Antrieb aufweist. Der Gussasphalt ist in einem Behälter bevorratet. Der Rührwerks-Antrieb dient zum Antreiben des Rührwerks. Zur Stromversorgung kann ein, insbesondere hoch schallisoliertes, Stromaggregat dienen, das Strom erzeugt. Das Stromaggregat kann Bestandteil der mobilen Arbeitsmaschine sein. Die mobile Arbeitsmaschine ist eigenständig betreibbar. Die mobile Arbeitsmaschine kann unabhängig von externer Versorgung betrieben werden. Das Stromaggregat gewährleistet die Stromerzeugung bei reduzierter Geräuschemission. Insbesondere beträgt ein Schalldruckpegel der Geräuschbelastung durch das Stromaggregat höchstens 70 dB, insbesondere höchstens 65 dB und insbesondere höchstens 64 dB in einer Entfernung von 7 m zur Schallquelle. Insbesondere ist die Geräuschemission des Stromaggregats gegenüber einem aus dem Stand der Technik bekannten HydraulikAggregat reduziert. Die mobile Arbeitsmaschine ist für den Einsatz in Bereichen geeignet, die hinsichtlich des Geräuschpegels sensibel sind, wie beispielsweise in einem Stadtgebiet. Die Geräuschbelastung insbesondere für eine Bedienperson der mobilen Arbeitsmaschine, ist reduziert. Das Risiko einer gesundheitlichen Beeinträchtigung und/oder gesundheitlichen Schädigung der Bedienperson aufgrund langjähriger Bedienung der mobilen Arbeitsmaschine ist reduziert. Die mobile Arbeitsmaschine ist flexibel einsetzbar und garantiert den Transport des fertig gemischten Gussasphalts von einer Gussasphalt-Herstellungsanlage zu einem Einsatzort. Wesentlich ist, dass der fertig gemischte Gussasphalt während des Transports mit Hilfe des Rührwerks in Bewegung gehalten wird. Dadurch ist gewährleistet, dass der erwärmte Gussasphalt während des Transports homogen bleibt und sich nicht entmischt. Die Verarbeitungsbedingungen für den transportierten Gussasphalt sind verbessert. Insbesondere bewirkt der Transport keine negative Beeinträchtigung der Materialqualität. Die mobile Arbeitsmaschine ist insbesondere für den Aufbau auf einen Lastkraftwagen geeignet. Das bedeutet, dass die Maße der Stellfläche der mobilen Arbeitsmaschine für den Transport im Straßenverkehr, insbesondere in Deutschland, ausgelegt sind. Typischerweise ist die Stellfläche der mobilen Arbeitsmaschine rechteckig und weist eine Länge von 5800 mm und eine Breite von 2500 mm auf.This object is achieved by a mobile machine with the features specified in claim 1. According to the invention, it has been recognized that a mobile working machine for the transport of mastic asphalt, which is in particular completely mixed, has an agitator with an electric agitator drive. The poured asphalt is stored in a container. The agitator drive is used to drive the agitator. For power supply can serve, in particular highly sound-insulated, power generator, which generates electricity. The generator can be part of the mobile machine. The mobile work machine is independently operable. The mobile work machine can be operated independently of external supply. The generator ensures power generation with reduced noise emission. In particular, a sound pressure level of the noise load by the generator is at most 70 dB, in particular at most 65 dB and in particular at most 64 dB at a distance of 7 m to the sound source. In particular, the noise emission of the generator is reduced compared to a hydraulic unit known from the prior art. The mobile work machine is suitable for use in areas that are sensitive in terms of noise level, such as in a city area. The noise level, in particular for an operator of the mobile work machine, is reduced. The risk of a health impairment and / or damage to the health of the operator due to many years of operation of the mobile work machine is reduced. The mobile machine can be used flexibly and guarantees the transport of the completely mixed cast asphalt from a mastic asphalt production plant to a place of work. It is essential that the ready-mixed mastic asphalt is kept in motion during transport by means of the agitator. This ensures that the heated mastic asphalt remains homogeneous during transport and does not segregate. The processing conditions for the transported mastic asphalt are improved. In particular, the transport does not cause a negative impact on the material quality. The mobile work machine is particularly suitable for mounting on a truck. This means that the dimensions of the footprint of the mobile machine are designed for transport by road, especially in Germany. Typically, the footprint of the mobile work machine is rectangular and has a length of 5800 mm and a width of 2500 mm.

Die mobile Arbeitsmaschine ist mit einer Schwenkeinheit zum Schwenken des Behälters um eine Schwenkachse mit einem Schwenkeinheit-Antrieb ausgeführt, der elektrisch ausgeführt ist und ermöglicht die Abgabe des Gussasphalts aus dem Behälter mittels elektrischer Antriebsenergie. Aus dem geschwenkten Behälter kann der Gussasphalt über die Abgabeöffnung in Folge der Schwerkraft selbsttätig abgegeben werden. Zusätzliche Abgabemittel sind entbehrlich. Insbesondere ist die Schwenkachse horizontal orientiert und insbesondere benachbart zur Abgabeöffnung angeordnet.The mobile working machine is provided with a pivoting unit for pivoting the container about a pivot axis with a pivoting unit drive, which is made electrically and allows the delivery of Gussasphalts from the container by means of electrical drive power.

In addition, an isolation system may be provided for the container to prevent unwanted heat loss from the container to the environment. In particular, the insulation system has one or more insulation layers, which are attached, for example, to an outside of the container for thermal insulation.

Eine mobile Arbeitsmaschine, bei der das Stromaggregat einen Verbrennungsmotor und einen Generator aufweist, ermöglicht eine unkomplizierte Bereitstellung elektrischer Energie. Der Verbrennungsmotor ist insbesondere als Dieselmotor ausgeführt.A mobile work machine, in which the generator has an internal combustion engine and a generator, allows an uncomplicated supply of electrical energy. The internal combustion engine is designed in particular as a diesel engine.

Eine mobile Arbeitsmaschine mit einem Elektroanschluss ermöglicht eine alternative oder zusätzliche Stromzufuhr. Insbesondere ermöglicht der Elektroanschluss ein Anschließen der mobilen Arbeitsmaschine an einen externen elektrischen Versorger, insbesondere an ein elektrisches Versorgungsnetz. Beispielsweise während eines Befüllvorgangs, während der Behälter der mobilen Arbeitsmaschine in einer Gussasphalt-Herstellungsanlage mit Gussasphalt beladen wird, kann die mobile Arbeitsmaschine, insbesondere die daran angeordneten elektrischen Verbraucher, insbesondere die elektrischen Antriebe, unmittelbar von dem elektrischen Versorgungsnetz mit elektrischen Strom versorgt werden. In diesem Fall ist ein Betreiben des Stromaggregats zum Erzeugen elektrischer Energie entbehrlich. Der Kraftstoffverbrauch und der damit verbundene Schadstoffausstoß sind reduziert. Insbesondere bei längeren Aufenthaltsdauern der mobilen Arbeitsmaschine in der Gussasphalt-Herstellungsanlage beispielsweise während einer morgendlichen Aufheizperiode einer Vorrichtung zur Herstellung des Gussasphalts und/oder bei einer längeren Wartedauer der mobilen Arbeitsmaschine vor einer Vorrichtung, ist das Einsparpotenzial von Kraftstoff- und Schadstoffausstoß erhöht.A mobile work machine with an electrical connection allows an alternative or additional power supply. In particular, the electrical connection makes it possible to connect the mobile working machine to an external electrical supplier, in particular to an electrical supply network. For example, during a filling operation, while the container of the mobile working machine is loaded with mastic asphalt in a mastic asphalt production plant, the mobile working machine, in particular the electrical consumers arranged thereon, in particular the electric drives, can be supplied with electric current directly from the electrical supply network. In this case, operating the generator for generating electrical energy is unnecessary. Fuel consumption and associated pollutant emissions are reduced. In particular, for longer periods of residence of the mobile machine in the mastic asphalt production plant, for example, during a morning heating period of a device for producing Gussasphalts and / or a longer waiting time of the mobile machine in front of a device, the potential savings of fuel and pollutant emissions is increased.

Bei einer mobilen Arbeitsmaschine mit einer zweiten Schließeinheit zum Schließen einer Abgabeöffnung des Behälters mit einem zweiten Schließeinheit-Antrieb, der elektrisch ausgeführt ist, ist ein vorteilhaftes Öffnen und Schließen der Abgabeöffnung ermöglicht. Die Abgabeöffnung dient zum Abgeben von Gussasphalt aus dem Behälter, insbesondere vor Ort auf einer Baustelle, zum Herstellen einer Asphaltschicht für eine Straße.In a mobile work machine with a second closing unit for closing a discharge opening of the container with a second closing unit drive, which is carried out electrically, an advantageous opening and closing of the discharge opening is made possible. The dispensing opening serves to dispense poured asphalt from the container, especially on site at a construction site, to produce an asphalt layer for a road.

Eine mobile Arbeitsmaschine, bei der die Schließeinheit einen Rundschwertschieber aufweist, ermöglicht eine komfortable Abgabe des Gussasphalts durch die Abgabeöffnung. Insbesondere ermöglicht der Rundschwertschieber ein dosiertes Abgeben des Gussasphalts durch veränderliches Einstellen einer Querschnittsfläche der Abgabeöffnung.A mobile work machine, in which the closing unit has a circular blade, allows a comfortable delivery of Gussasphalts through the discharge opening. In particular, the roundabout slider allows metered dispensing of the casting asphalt by variably adjusting a cross-sectional area of the dispensing opening.

Eine mobile Arbeitsmaschine, bei der der zweite Schließeinheit-Antrieb als zweites Spindelhubgetriebe ausgeführt ist, ist die Betätigung und insbesondere die Handhabung des Rundschwertschiebers vereinfacht und insbesondere komfortabel. Insbesondere greift das zweite Spindelhubgetriebe an einem Exzenterhebel des Rundschwertschiebers an. Eine lineare Stellbewegung des zweiten Spindelhubgetriebes kann unmittelbar in eine rotatorische Öffnungs- und Schließbewegung umgesetzt werden.A mobile work machine, in which the second clamping unit drive is designed as a second screw jack, the operation and in particular the handling of the rotary blade slider is simplified and in particular comfortable. In particular, the second screw jack engages an eccentric lever of the rotary blade slider. A linear adjusting movement of the second Spindelhubgetriebes can be converted directly into a rotary opening and closing movement.

Eine mobile Arbeitsmaschine, bei der der Rührwerksantrieb eine Planeten-Kegelrad-Getriebekombination und/oder einen Frequenzumformer auf weist, ermöglicht eine vorteilhafte Mischung des Gussasphalts in dem Behälter. Insbesondere kann mittels des Frequenzumformers eine Antriebsdrehzahl, also eine Rührwerksdrehzahl, stufenlos eingestellt werden. Insbesondere ist es möglich, die Drehrichtung des Rührwerks flexibel zu verändern. Die Planeten-Kegelrad-Getriebekombination ermöglicht eine effektive und robuste Übertragung der Antriebsdrehbewegung des Rührwerk-Antriebs zum Mischen des Gussasphalts.A mobile work machine in which the agitator drive a planetary bevel gear combination and / or a frequency converter has, allows an advantageous mixture of Gussasphalts in the container. In particular, by means of the frequency converter, a drive speed, that is to say an agitator speed, can be adjusted continuously. In particular, it is possible to change the direction of rotation of the agitator flexible. The planetary bevel gear combination allows effective and robust transmission of the drive rotation of the agitator drive to mix the casting asphalt.

Eine mobile Arbeitsmaschine, bei der der Schwenkeinheit-Antrieb mindestens eine Spindelhubanlage und insbesondere genau zwei Spindelhubanlagen, aufweist, ermöglicht eine vereinfachte, insbesondere selbsttätige Abgabe des Gussasphalts durch die Abgabeöffnung.A mobile working machine, in which the swivel unit drive has at least one screw lifting unit and in particular exactly two screw lifting units, enables a simplified, in particular automatic, delivery of the cast asphalt through the dispensing opening.

Insbesondere ist es denkbar, dass sämtliche Antriebe der mobilen Arbeitsmaschine elektrisch ausgeführt sind. Sämtliche Antriebe sind dann mittels einer einzigen, elektrischen Stromversorgungseinheit, dem Stromaggregat, bedienbar. Weitere Energieversorgungseinheiten sind entbehrlich. Die mobile Arbeitsmaschine ist unaufwendig ausgeführt.In particular, it is conceivable that all drives of the mobile work machine are designed electrically. All drives are then powered by a single, electrical power unit, the generator set, operable. Further power supply units are unnecessary. The mobile machine is inexpensive.

Für eine mobile Arbeitsmaschine mit einem Rahmen, der eine Unterkonstruktion der mobilen Arbeitsmaschine bildet, ist die Montage auf einem Lastkraftwagen unkompliziert möglich. Insbesondere umfasst der Rahmen mehrere fest miteinander verbundene Profilelemente. Der Rahmen kann Befestigungshilfen aufweisen, um eine Befestigung des Rahmens am Lastkraftwagen zu vereinfachen.For a mobile work machine with a frame that forms a substructure of the mobile work machine, the mounting on a truck is easily possible. In particular, the frame comprises a plurality of permanently connected profile elements. The frame may include attachment aids to facilitate attachment of the frame to the truck.

Die elektrische Steuerung ist insbesondere in einem Schaltschrank zentral angeordnet. Die elektrische Steuerung weist insbesondere eine Energiespeichereinheit auf. Beispielsweise ist es möglich, dass überschüssige elektrische Energie, beispielsweise während einer Wartedauer der mobilen Arbeitsmaschine in der Gussasphalt-Herstellungsanlage, von einem elektrischen Versorgungsnetz an die elektrische Steuerung übertragen und in der Energiespeichereinheit gespeichert wird. Es ist zusätzlich möglich, während einer Transportfahrt der mobilen Arbeitsmaschine auf einem Lastkraftwagen elektrische Energie mittels des Stromaggregats zu erzeugen und zur Speicherung in die Energiespeichereinheit zu übermitteln. Bei Bedarf elektrischer Energie beispielsweise für mindestens einen der Antriebe, kann in der Energiespeichereinheit gespeicherte Energie unmittelbar den elektrischen Verbrauchern zugeführt werden. In diesem Fall ist es nicht erforderlich, dass das Stromaggregat betrieben wird. Der Kraftstoffverbrauch und der damit verbundene Schadstoffausstoß sind reduziert.A mobile work machine with an electrical control simplifies the controlled power supply and in particular the actuation of the electric drives and / or the electrically controlled heating unit. The electrical control is arranged centrally, in particular in a control cabinet. The electrical control in particular has an energy storage unit. For example, it is possible that excess electrical energy, for example, during a waiting period of the mobile machine in the mastic asphalt production plant, transmitted from an electrical supply network to the electrical control and stored in the energy storage unit. It is additionally possible to generate electrical energy by means of the generator unit during transport of the mobile work machine on a truck and to transmit it for storage in the energy storage unit. If electrical energy is required, for example for at least one of the drives, energy stored in the energy storage unit can be directly supplied to the electrical consumers. In this case, it is not necessary that the generator is operated. Fuel consumption and associated pollutant emissions are reduced.

Mittels des Rahmens 2 ist die mobile Arbeitsmaschine 1 fest und zuverlässig an dem Lastkraftwagen befestigbar. Der Rahmen 2 ist insbesondere horizontal auf einem Lastkraftwagen für den Transport des Gussasphalts angeordnet.An in Fig. 1 to 5 illustrated mobile machine 1 is used for the transport of ready mixed mastic asphalt. The mobile work machine 1 can be arranged on a truck, not shown. The mobile work machine 1 has a frame 2 arranged at the bottom. The frame 2 comprises a plurality of profile-shaped frame members which are fixedly connected to each other. The frame elements are designed as metal profile elements, in particular made of steel, and welded together. The frame 2 forms a substructure for the mobile work machine. The frame 2 has not shown connecting elements. The frame 2 allows a quick and easy connection of the work machine 1 to the truck. By means of the frame 2, the mobile work machine 1 is firmly and reliably fastened to the truck. The frame 2 is arranged in particular horizontally on a truck for the transport of Gussasphalts.

Die mobile Arbeitsmaschine 1 weist einen Behälter 3 auf, der zum Bevorraten des Gussasphalts dient. Der Behälter 3 ist im Wesentlichen hohlzylindrisch ausgeführt, wobei eine Längsachse des Behälters 3 parallel zu der von dem Rahmen 2 festgelegten Ebene orientiert ist. Während des Transports des Gussasphalts ist der Behälter 3 im Wesentlichen horizontal angeordnet.The mobile work machine 1 has a container 3, which serves for storing the Gussasphalts. The container 3 is substantially hollow cylindrical executed, wherein a longitudinal axis of the container 3 is oriented parallel to the plane defined by the frame 2 level. During the transport of the cast asphalt, the container 3 is arranged substantially horizontally.

Der Behälter 3 weist eine vordere Stirnseite 4 und eine hintere Stirnseite 5 auf. In einem auf einem Lastkraftwagen angeordneten Zustand der mobilen Arbeitsmaschine 1 ist die vordere Stirnseite 4 in Fahrrichtung des Lastkraftwagens orientiert. Die vordere Stirnseite 4 ist einem Fahrerhaus des Lastkraftwagens zugewandt. Die hintere Stirnseite 5 ist entgegen der Fahrrichtung des Lastkraftwagens orientiert. Die hintere Stirnseite 5 ist dem Fahrerhaus des Lastkraftwagens abgewandt. An der hinteren Stirnseite 5 ist eine Abgabeöffnung zum Abgeben von Gussasphalt aus dem Behälter 3 vorgesehen. An der Abgabeöffnung ist ein Abgabeleitblech 6 mit Trichterelement 7 vorgesehen, um eine gezielte und kontrollierte Abgabe des Gussasphalts aus dem Behälter 3 zu ermöglichen. Das Abgabeleitblech 6 ist zylinderschalenförmig ausgeführt.The container 3 has a front end face 4 and a rear end face 5. In a state arranged on a truck of the mobile work machine 1, the front end face 4 is oriented in the direction of travel of the truck. The front end 4 faces a cab of the truck. The rear end face 5 is oriented counter to the direction of travel of the truck. The rear end face 5 faces away from the cab of the truck. At the rear end face 5, a discharge opening for discharging poured asphalt from the container 3 is provided. At the discharge opening a Abgabeleitblech 6 is provided with funnel element 7 to allow a targeted and controlled delivery of Gussasphalts from the container 3. The Ausschabeleitblech 6 is executed cylindrical shell.

An einer Oberseite 8 des Behälters 3 ist eine Einfüllöffnung zum Einfüllen des Gussasphalts aus der Gussasphalt-Herstellungsanlage vorgesehen. Durch die Einfüllöffnung kann der fertig gemischte fließfähige Gussasphalt selbsttätig in Folge von Schwerkraft aus einer Vorrichtung zur Herstellung von Gussasphalt unmittelbar in den Behälter 3 fließen. Dazu wird die mobile Arbeitsmaschine 1 mit geöffneter Einfüllöffnung unter einer Ausgabeöffnung der Vorrichtung angeordnet. Das Einfüllen des Gussasphalts in den Behälter 3 der Arbeitsmaschine 1 ist vereinfacht.On an upper side 8 of the container 3, a filling opening is provided for filling the cast asphalt from the mastic asphalt production plant. As a result of gravity, the ready-mixed flowable mastic asphalt can flow directly into the container 3 from a device for producing mastic asphalt through the filling opening. For this purpose, the mobile work machine 1 is arranged with an open filling opening under a dispensing opening of the device. The filling of Gussasphalts in the container 3 of the working machine 1 is simplified.

Zum Öffnen und Schließen der Einfüllöffnung ist eine erste Schließeinheit 9 vorgesehen. Die erste Schließeinheit 9 weist einen ersten Schließeinheit-Antrieb 10 aus. Der erste Schließeinheit-Antrieb 10 ist elektrisch ausgeführt. Der erste Schließeinheit-Antrieb 10 weist einen ersten Elektromotor 11 auf. Der erste Schließeinheit-Antrieb 10 ist als erstes Spindelhubgetriebe ausgeführt. Der erste Elektromotor 11 erzeugt eine Antriebsdrehbewegung die mittels eines Getriebes auf einen Spindelhubantrieb übertragen wird, der mit dem Flachschieber 12 unmittelbar verbunden ist. In der in Fig. 1 und 2 gezeigten Anordnung ist der Flachschieber 12 über der Einfüllöffnung angeordnet. Die Einfüllöffnung ist abgedeckt deshalb nicht erkennbar. In dieser Anordnung ist die Einfüllöffnung des Behälters 3 verschlossen. Ein Einfüllen von Gussasphalt ist in diesem Zustand nicht möglich. Durch Betätigen des ersten Schließeinheit-Antriebs 10 wird der Flachschieber gemäß Fig. 1 nach links verlagert. Dadurch wird die Einfüllöffnung des Behälters 3 freigegeben.For opening and closing the filling opening, a first closing unit 9 is provided. The first closing unit 9 has a first closing unit drive 10 off. The first clamping unit drive 10 is designed electrically. The first closing unit drive 10 has a first electric motor 11. The first clamping unit drive 10 is designed as a first screw jack. The first electric motor 11 generates a drive rotational movement which is transmitted by means of a gear to a Spindelhubantrieb, which is directly connected to the flat slide 12. In the in Fig. 1 and 2 As shown, the flat slide 12 is arranged above the filling opening. The filling opening is therefore not visible covered. In this arrangement, the filling opening of the container 3 is closed. The filling of mastic asphalt is not possible in this condition. By pressing the first closing unit drive 10 of the flat slide is according to Fig. 1 shifted to the left. As a result, the filling opening of the container 3 is released.

Unterhalb des Flachschiebers 12 ist an der Einfüllöffnung ein zusätzliches Fallschutzgitter 34 angeordnet. Das Fallschutzgitter 34 ist zweiflüglig ausgeführt und horizontal orientiert. Die drehbar gelagerten Flügel des Fallschutzgitters 34 können beispielsweise zu Wartungszwecken für Arbeiten innerhalb des Behälters 3 nach oben geklappt werden. Der Behälter 3 ist dann über die Einfüllöffnung zugänglich.Below the flat slide 12, an additional fall protection grid 34 is arranged at the filling opening. The fall arrest grid 34 is executed two-winged and horizontally oriented. The rotatably mounted wings of the fall arrest grid 34 can be folded up, for example for maintenance purposes for working within the container 3. The container 3 is then accessible via the filling opening.

Die Verlagerung des Flachschiebers 12 ist durch eine Schließeinheit-Linearführung 13 vereinfacht. Die Schließeinheit-Linearführung 13 weist zwei jeweils entlang einer Verlagerungsrichtung des Flachschiebers 12 orientierte Führungsschienen 14 auf. Entlang der Führungsschienen 14 kann jeweils mindestens eine Führungsrolle des Flachschiebers 12 geführt rollen. Die Verlagerung des Flachschiebers 12 ist mit reduziertem Kraftaufwand möglich. Ein für die Verlagerung erforderlicher Energiebedarf, insbesondere ein elektrischer Energiebedarf, ist reduziert.The displacement of the flat slide 12 is simplified by a closing unit linear guide 13. The closing unit linear guide 13 has two guide rails 14, each oriented along a direction of displacement of the flat slide 12. Along the guide rails 14, at least one guide roller of the flat slide 12 can each roll guided. The displacement of the flat slide 12 is possible with reduced effort. An energy requirement required for the relocation, in particular an electrical energy requirement, is reduced.

An der hinteren Stirnseite 5 ist an der Abgabeöffnung eine zweite Schließeinheit 15 vorgesehen. Die zweite Schließeinheit 15 umfasst einen zweiten Schließeinheit-Antrieb 16 mit einem zweiten Elektromotor 17. Der zweite Schließeinheit-Antrieb 16 ist elektrisch ausgeführt. Der zweite Schließeinheit-Antrieb 16 ist als zweites Spindelhubgetriebe ausgeführt. Das zweite Spindelhubgetriebe ist im Wesentlichen vertikal orientiert. Eine von dem zweiten Spindelhubgetriebe ausgeführte Verlagerungsrichtung ist im Wesentlichen vertikal orientiert. Die zweite Schließeinheit 15 weist einen Rundschwertschieber 18 auf. Der Rundschwertschieber 18 weist ein um eine Drehachse 19 drehbares Verschlusselement 20 auf. Das Verschlusselement 20 ist plattenförmig ausgeführt. Die Platte des Verschlusselements 20 weist einen ersten Konturabschnitt auf, der kreisbogenförmig bezogen auf die Drehachse 19 ausgeführt ist. Die Platte weist einen zweiten Konturabschnitt auf, der gegenüber der Drehachse 19 eine von einer Kreiskontur verschiedene Kontur aufweist. Die durch das Verschlusselement 20 des Rundschwertschiebers 18 verdeckte Abgabeöffnung ist in der gezeigten Anordnung gemäß Fig. 2 und 4 des Rundschwertschiebers 18 abgedeckt. Eine Abgabe von Gussasphalt aus dem Behälter 3 ist in dieser Anordnung nicht möglich.At the rear end face 5, a second closing unit 15 is provided at the discharge opening. The second closing unit 15 comprises a second closing unit drive 16 with a second electric motor 17. The second closing unit drive 16 is designed electrically. The second clamping unit drive 16 is designed as a second screw jack. The second screw jack is oriented substantially vertically. A displacement direction performed by the second screw jack is oriented substantially vertically. The second closing unit 15 has a circular blade valve 18. The round blade valve 18 has a closure element 20 rotatable about a rotation axis 19. The closure element 20 is designed plate-shaped. The plate of the closure element 20 has a first contour section, which is executed in a circular arc with respect to the axis of rotation 19. The plate has a second contour section which, with respect to the axis of rotation 19, has a contour which is different from a circular contour. The hidden by the closure element 20 of the circular blade valve 18 discharge opening is in the arrangement shown in accordance with Fig. 2 and 4 covered by the circular blade valve 18. A delivery of mastic asphalt from the container 3 is not possible in this arrangement.

Der zweite Schließeinheit-Antrieb 16 ist mit einem Exzenterhebel 21 des Rundschwertschiebers 18 verbunden. Der Exzenterhebel 21 ist exzentrisch zur Drehachse 19 angeordnet. Der Exzenterhebel 21 ist einteilig an dem Rundschwertschieber 18 angeformt. Bei einer Betätigung des zweiten Schließeinheit-Antriebs 16 entlang der vertikalen Verlagerungsrichtung wird der Exzenterhebel gemäß Fig. 4 nach unten verlagert. Das Verschlusselement 20 des Rundschwertschiebers 18 wird im Uhrzeigersinn um die Drehachse 19 gedreht, sodass der zweite Konturabschnitt zumindest bereichsweise mit der hinter dem Rundschwertschieber 18 angeordneten Abgabeöffnung zur Überlagerung kommt. Dadurch, dass die Platte des Rundschwertschiebers 18 bezüglich der Drehachse 19 eine unrunde Kontur aufweist, bewirkt die Drehung des Rundschwertschiebers 18 um die Drehachse 19, dass ein nicht abgedeckter Teilbereich der Abgabeöffnung veränderlich ist. Ein Abgeben des Gussasphalts aus dem Behälter 3 über die Abgabeöffnung ist dann möglich.The second closing unit drive 16 is connected to an eccentric lever 21 of the circular blade slide 18. The eccentric lever 21 is arranged eccentrically to the axis of rotation 19. The eccentric lever 21 is integrally formed on the circular blade slider 18. Upon actuation of the second clamping unit drive 16 along the vertical displacement direction of the eccentric lever is according to Fig. 4 shifted down. The closure element 20 of the circular blade slider 18 is rotated clockwise about the axis of rotation 19, so that the second contour portion at least partially superimposed with the disposed behind the circular vane slide 18 discharge opening. Characterized in that the plate of the circular vane slider 18 with respect to the axis of rotation 19 has a non-circular contour, causes the rotation of the circular vane slider 18 about the rotation axis 19, that an uncovered portion of the discharge opening is variable. Dispensing the Gussasphalts from the container 3 via the discharge opening is then possible.

Seitlich an dem Behälter 3 ist eine Plattform 22 mit Geländer angeordnet. Dadurch wird einem Bediener die Betätigung der mobilen Arbeitsmaschine 1 erleichtert. Insbesondere ist die Begehbarkeit des Behälters 3 und insbesondere eine Zugänglichkeit des ersten Schließeinheit-Antriebs 10 vereinfacht. In der Plattform 22 ist Stauraum für Werkzeuge und/oder Betriebsmittel integriert, der über Klappen 23 zugänglich ist. Neben den Klappen 23 ist in die Plattform 22 ein Tank 44 integriert.

Das zum Betreiben des Öl-Gebläse-Brenners erforderliche Heizöl ist in dem Tank 44 bevorratet.Laterally on the container 3, a platform 22 is arranged with railing. This facilitates the operation of the mobile work machine 1 to an operator. In particular, the accessibility of the container 3 and in particular an accessibility of the first clamping unit drive 10 is simplified. In the platform 22 storage space for tools and / or resources is integrated, which is accessible via flaps 23. In addition to the flaps 23, a tank 44 is integrated into the platform 22. The tank 44 is connected to arranged at the rear end 5 heating units 24. The heating units 24 are each designed as an oil-blower burner. The fuel oil required to operate the oil-blower burner is stored in the tank 44.

Die Heizeinheiten 24 dienen zum Beheizen des Behälters 3. Die Heizeinheiten 24 sind in einem unteren Bereich des Behälters 3 angeordnet. In dem unteren Bereich des Behälters 3 wird sich der schließfähige Gussasphalt während des Transports im Wesentlichen anordnen. Die Heizeinheiten 24 werden elektrisch angesteuert. Die Heizeinheiten 24 sind bezogen auf die Abgabeöffnung des Behälters 3 beidseitig angeordnet.The heating units 24 serve to heat the container 3.

The lighting element 35 facilitates one Operator handling, especially the delivery of Gussasphalts on site on site, especially in low light conditions.

Im Inneren des Behälters 3 ist ein Rührwerk 25 angeordnet, das zum Rühren des Gussasphalts dient. Das Rührwerk 25 weist einen elektrischen Rührwerk-Antrieb 26 zum Antreiben des Rührwerks 25 auf. Der Rührwerk-Antrieb 26 umfasst eine Planeten-Kegelrad-Getriebekombination 27 und einen nicht dargestellten Frequenzumformer. Der Frequenzumformer ist in einem Schaltschrank 43 angeordnet. Mittels der Planeten-Kegelrad-Getriebekombination 27 wird die von einem dritten Elektromotor 28 des Rührwerk-Antriebs 26 zur Verfügung gestellte elektrische Antriebsenergie in eine Antriebsdrehbewegung mit dem erforderlichen hohen Antriebsdrehmoment umgesetzt.Inside the container 3, an agitator 25 is arranged, which serves to stir the Gussasphalts. The agitator 25 has an electric agitator drive 26 for driving the agitator 25. The agitator drive 26 includes a planetary bevel gear combination 27 and a frequency converter, not shown. The frequency converter is arranged in a control cabinet 43. By means of the planetary bevel gear combination 27, the electrical drive energy provided by a third electric motor 28 of the agitator drive 26 is converted into a drive rotational movement with the required high drive torque.

Das Rührwerk 25 weist eine entlang einer Rührachse 29 orientierte Antriebswelle 30 auf. Die Rührachse 29 ist in den Anordnungen des Rührbehälters 3 gemäß Fig. 1 bis 5 horizontal orientiert, also parallel zu dem Rahmen 2. Entlang der Rührachse 29 sind an der Antriebswelle 30 mehrere Rührelemente 31 angeordnet.

Die Rührelemente 31 weisen einen Rührarm 32 und ein an einem freien Ende des Rührarms 32 befestigtes Rührschild 33 auf. Das Rührschild 33 ist im Wesentlichen rechteckförmig ausgeführt. Das Rührschild 33 ist gegenüber einer Umfangsrichtung der Drehbewegung des Rührwerks 25 geneigt angeordnet. Die Rührelemente 31 bewirken ein Vermischen des Gussasphalts in dem Behälter 3. Aufgrund der geneigten Anordnung der Rührschilde 33 erfolgt eine Transportbewegung des Gussasphalts in dem Behälter 3 zu der Abgabeöffnung hin. An der Antriebswelle 30 sind acht Rührelemente 31 angeordnet. Jeweils 2 benachbarte Rührelemente 31 entlang der Rührachse 29 sind bezogen auf die Rührachse 29 um einen Drehwinkel von 90° versetzt angeordnet.The agitator 25 has a drive shaft 30 oriented along a stirring axis 29.

The stirring elements 31 are fixed to the drive shaft 30 and extend substantially radially from the stirring axis 29. The stirring elements 31 have a stirring arm 32 and a stirring blade 33 attached to a free end of the stirring arm 32. The stirring blade 33 is designed substantially rectangular. The stirring blade 33 is inclined relative to a circumferential direction of the rotational movement of the agitator 25. The stirring elements 31 cause a mixing of the casting asphalt in the container 3. Due to the inclined arrangement of the stirring blades 33, a transport movement of the casting asphalt in the container 3 takes place towards the discharge opening. On the drive shaft 30 eight stirring elements 31 are arranged. 2 adjacent stirring elements 31 along the stirring axis 29 are arranged offset relative to the stirring axis 29 by a rotation angle of 90 °.

Der Rührwerks-Antrieb 26 ist mittels eines Schutzblechs 36, insbesondere nach obenhin, zum Schutz gegen Witterungseinflüsse abgeschirmt.The agitator drive 26 is shielded by means of a protective plate 36, in particular upwards, to protect against the effects of weather.

Der Rührwerks-Antrieb 26 ist fest mit dem Behälter 3 verbunden. Insbesondere ist der Rührwerks-Antrieb 26 nicht mit dem Rahmen 2 verbunden.
