Description

Die Erfindung betrifft eine Vorrichtung zur Aufnahme und zum Antrieb eines Aggregats zum Aufbereiten, insbesondere Zerkleinern, Klassieren und/oder Sortieren, von stückigem Aufgabegut. Weiters betrifft die Erfindung die Verwendung einer solchen Vorrichtung zur Aufnahme und zum Antrieb eines Aggregats, das zum Aufbereiten, insbesondere Zerkleinern, Klassieren und/oder Sortieren, von stückigem Aufgabegut geeignet ist.The invention relates to a device for receiving and driving a unit for processing, in particular crushing, classifying and/or sorting, of lumpy feed material. Furthermore, the invention relates to the use of such a device for accommodating and driving a unit that is suitable for processing, in particular crushing, classifying and/or sorting, of lumpy feed material.

Weiters betrifft die Erfindung eine Vorrichtung zum Aufbereiten, insbesondere Zerkleinern, Klassieren und/oder Sortieren, von stückigem Aufgabegut.Furthermore, the invention relates to a device for processing, in particular crushing, classifying and/or sorting, of lumpy feed material.

Die Aufbereitung von stückigem Aufgabegut hat beispielswiese bei der industriellen Aufbereitung von mineralischen Rohstoffen, wie z.B. im Steinbruch, im Kieswerk und im Bergbau, sowie bei der Aufbereitung von Sekundärmaterialien, wie z.B. im Recycling von Bauschutt, eine große Bedeutung. Die Aufbereitung umfasst dabei insbesondere das Zerkleinern, Klassieren und/oder Sortieren des stückigen Aufgabeguts. Für die Zerkleinerung kommen typischerweise Brecher zum Einsatz. Das Klassieren erfolgt mit Hilfe von Siebvorrichtungen.The processing of lumpy feed material is of great importance, for example, in the industrial processing of mineral raw materials, e.g. in quarries, gravel works and in mining, as well as in the processing of secondary materials, e.g. in the recycling of building rubble. The processing includes in particular the crushing, classifying and/or sorting of the lumpy input material. Crushers are typically used for comminution. The classification is done with the help of sieving devices.

Von Brechern spricht man, wenn diese eine Zerkleinerung des Aufgabeguts zu Korngrößen im groben bis mittleren Größenbereich erlauben, d.h. auf eine Korngröße von bis zu 1-10mm. Im Unterschied dazu spricht man von Mühlen, wenn die Zielkörnung im darunter liegenden Fein- oder Feinstbereich liegen soll. Brecher können sowohl stationär als auch mobil (auf Rädern oder auf Raupenketten) eingesetzt werden.One speaks of crushers when they allow crushing of the input material to grain sizes in the coarse to medium size range, ie to a grain size of up to 1-10mm. In contrast, one speaks of mills when the target grain size is to be in the fine or finest range below. Crushers can be used both stationary and mobile (on wheels or on caterpillar tracks).

Mobile Brecher, wie z.B. aus der US 5 431 350 A bekannt, haben gegenüber stationären Brechern den Vorteil, dass sie auf der Baustelle oder innerhalb eines Abbruchfeldes bewegt werden können. Anstatt das Aufgabegut von den wechselnden Orten seines Anfallens über weite Strecken zum stationären Brecher zu transportieren, was hohe Transportkosten verursacht, können mobile Brecher mit Hilfe ihres integrierten Fahrwerks auf der Baustelle oder im Abbruchfeld in einfacher Weise nachgeführt werden, um dem Ort des Materialanfalls zu folgen. Vollmobile Brechanlagen mit fest installiertem Raupenfahrwerk können dabei beispielsweise von Baggern befüllt werden. Das zerkleinerte Material kann dann an Ort und Stelle weiterverarbeitet oder über versetzbare Bandanlagen oder mit Radladern weitertransportiert werden.Mobile crushers, such as from the U.S. 5,431,350 A known, have the advantage over stationary crushers that they can be moved on the construction site or within a demolition field. Instead of transporting the feed material from the changing places where it accumulates over long distances to the stationary crusher, which causes high transport costs, mobile crushers can easily be tracked with the help of their integrated chassis on the construction site or in the demolition field in order to follow the place where the material accumulates . Fully mobile crushing plants with permanently installed crawler tracks can be filled by excavators, for example. The shredded material can then be further processed on site or further transported via mobile conveyor systems or wheel loaders.

Ein weitere Vorteil von mobilen Brechern liegt darin, dass sie aufgrund des relativ geringen Transportgewichts mit herkömmlichen Transportvorrichtungen zur jeweiligen Baustelle oder zum jeweiligen Abbruchfeld gebracht werden können, ohne in ihre Einzelbestandteile zerlegt werden zu müssen.Another advantage of mobile crushers is that, due to the relatively low transport weight, they can be brought to the respective construction site or demolition field with conventional transport devices without having to be dismantled into their individual components.

Der mobile Einsatz von Brechern wird auch durch Brecherlöffel, insbesondere Backenbrecherlöffel möglich. Es handelt sich dabei um ein Anbaugerät für Bagger, das mit Hilfe von eingebauten Brechbacken das Aufgabegut, wie z.B. Bauschutt und Abbruchmaterial, zerkleinern kann. Ein Brecherlöffel hat die Bauform einer Schaufel, mit welcher das zu brechende Material wie mit einer herkömmlichen Baggerschaufel aufgenommen werden kann und die hinten für den Austritt des zerkleinerten Materials geöffnet ist. Im Vergleich zu normalen Backenbrechern hat der Backenbrecherlöffel eine geringere Produktion, kann aber einfacher transportiert werden und benötigt für seinen Betrieb leidglich einen Bagger. Ein Backenbrecherlöffel ist beispielsweise in der WO 2004/020747 A1 beschrieben.The mobile use of crushers is also made possible by crusher buckets, in particular jaw crusher buckets. This is an attachment for excavators that can crush the feed material, such as building rubble and demolition material, with the help of built-in crushing jaws. A crusher bucket has the shape of a shovel, with which the material to be crushed can be picked up like a conventional excavator shovel and which is open at the back for the crushed material to exit. Compared with normal jaw crusher, jaw crusher bucket has lower production but can easier to transport and only requires an excavator to operate. A jaw crusher spoon is for example in the WO 2004/020747 A1 described.

Der Backenbrecherlöffel arbeitet mit dem hydraulischen System des Baggers. Die Schläuche des Baggers, für Ölzu- und -ablauf, werden direkt mit dem Brecherlöffel verbunden. Ein Hydraulikblock reguliert den Ölfluss und den Öldruck, um die richtige Menge an den Hydraulikmotor abzugeben.The crusher bucket works with the hydraulic system of the excavator. The excavator's hoses for the oil supply and drain are connected directly to the crusher bucket. A hydraulic block regulates the oil flow and oil pressure to deliver the right amount to the hydraulic motor.

Während des Brechvorgangs wird der Brecherlöffel senkrecht positioniert, damit das Material unten herausfallen kann. Brecherlöffel haben im Vergleich zu mobilen Brechern folgende Vorteile: Auf Grund der Ausbildung des Brechers als Anbaugerät für Bagger kann der Brecher in einfacher Weise aus- und angebaut werden. Dadurch ist ein einfacher Wechsel zwischen unterschiedlichen Anbaugeräten möglich. Weiters ist der Brecher wegen der Anordnung an einem Baggerarm höhenverstellbar, sodass der jeweils benötigte Abstand zum Boden oder zu einer darunter angeordneten Abfördereinrichtung eingestellt werden kann. Insbesondere ist das Zerkleinern von stahlarmiertem Beton, wie z.B. Bahnschwellen, mit herkömmlichen mobilen Brecheranlagen nicht möglich, weil die am Auslauf des Brechers gemeinsam mit dem zerkleinerten Beton austretenden Stahlstäbe einen gewissen Platzbedarf in Höhenrichtung haben, der bei mobilen Brechern nicht vorhanden ist. Schließlich haben Brecherlöffel den Vorteil, dass der Brecher wegen seiner Befestigung am Baggerarm in einfacher Weise gekippt oder gerüttelt werden kann, um Verstopfungen oder Blockaden des Baggers zu lösen.During the crushing process, the crusher bucket is positioned vertically so that the material can fall out at the bottom. Crushing buckets have the following advantages compared to mobile crushers: Due to the design of the crusher as an attachment for excavators, the crusher can be easily removed and attached. This makes it easy to switch between different attachments. Furthermore, the crusher can be adjusted in height due to the arrangement on an excavator arm, so that the required distance to the ground or to a discharge device arranged below can be set. In particular, the crushing of steel-reinforced concrete, such as railway sleepers, is not possible with conventional mobile crushers because the steel rods exiting the crusher together with the crushed concrete require a certain amount of space in the vertical direction, which is not available with mobile crushers. Finally, crusher buckets have the advantage that because the crusher is attached to the excavator arm, it can easily be tilted or shaken to clear blockages or blockages in the excavator.

Nachteilig bei Brecherlöffeln ist jedoch der Produktionsstillstand des Brechers während der Materialaufnahme mit dem Anbaugerät, sodass die Produktionskapazität gering ist. Im Vergleich zu stationären Brechern haben Systeme mit Brecherlöffel den Nachteil, dass der Bagger, an dessen Arm das Anbaugerät angeordnet ist, für andere Arbeiten blockiert ist.However, the disadvantage of crusher buckets is that the crusher stops production while the material is being picked up with the attachment, so that the production capacity is low. Compared to stationary crushers, systems with crusher buckets have the disadvantage that the excavator, on whose arm the attachment is arranged, is blocked for other work.

Die Erfindung zielt daher darauf ab, eine verbesserte Vorrichtung zur Durchführung von Brecharbeiten oder anderen Aufbereitungsarbeiten, insbesondere Klassier- oder Sortierarbeiten, zu schaffen, wobei eine hohe Produktionskapazität erreicht werden soll und die Transportwege minimiert werden sollen.The invention therefore aims to create an improved device for carrying out crushing work or other processing work, in particular classification or sorting work, with a high production capacity being to be achieved and the transport routes being to be minimized.

Zur Lösung dieser Aufgabe sieht die Erfindung eine stationäre Vorrichtung nach Anspruch 1 vor.To solve this problem, the invention provides a stationary device according to claim 1.

Die Erfindung ermöglicht somit den Einsatz eines eigentlich für mobile Fahrzeuge, insbesondere Bagger, vorgesehenen Anbaugeräts an einer stationären Einrichtung. An der stationären Einrichtung wird das Anbaugerät, wie z.B. ein Brecherlöffel, lediglich für die Aufbereitung des Materials eingesetzt, nicht jedoch für die Materialaufnahme. Durch einen solchen stationären Betrieb wird das Aufgabematerial von einem Beschickergerät (wie z.B. Bagger, Radlader etc.) direkt in das Anbaugerät aufgegeben, womit der durch die Materialaufnahme mit dem Anbaugerät verursachte Produktionsstillstand vermieden wird. Die dadurch ermöglichte konstante Beschickung des Anbaugerätes mit Material ermöglicht daher eine Produktionssteigerung des Anbaugerätes um bis zu 50 %. Damit reduzieren sich auch die Betriebskosten auf ein Minimum.The invention thus enables the use of an attachment that is actually intended for mobile vehicles, in particular excavators, on a stationary device. At the stationary device, the attachment, such as a crusher bucket, is only used for processing the material, but not for picking up the material. With such stationary operation, the feed material is fed directly into the attachment by a feeder (such as excavators, wheel loaders, etc.), thus avoiding the production downtime caused by the material being picked up by the attachment. The constant supply of material to the attachment that is made possible in this way means that the output of the attachment can be increased by up to 50%. This also reduces the operating costs to a minimum.

Die Erfindung schafft weiters eine große Flexibilität, weil Anbaugeräte dadurch sowohl mobil auf einen Bagger oder Radlader als auch stationär verwendet werden können. Da Anbaugeräte für einen raschen An- und Abbau ausgelegt sind, ist ein einfacher Wechsel zwischen den beiden genannten Einsatzarten möglich. Weiters ist auch ein Wechsel zwischen verschiedenen Anbaugeräten in einfacher Weise möglich.The invention also creates great flexibility because attachments can be used both mobile on an excavator or wheel loader and stationary. Since attachments are designed for quick attachment and detachment, it is easy to switch between the two types of use mentioned. Furthermore, changing between different attachments is also possible in a simple manner.

Die erfindungsgemäße stationäre Vorrichtung weist eine stationäre, insbesondere rahmenförmige Stützkonstruktion auf, die ein Tragelement mit Befestigungsmitteln zum lösbaren Befestigen des Anbaugeräts trägt bzw. abstützt. Die stationäre Ausbildung des Rahmens bedeutet, dass die Vorrichtung keinen Fahrantrieb aufweist. Bevorzugt umfasst die erfindungsgemäße Vorrichtung auch kein fest angebautes Fahrwerk, wie z.B. ein Raupenfahrwerk oder Räder. Zur Abstützung am Untergrund umfasst die Stützkonstruktion bevorzugt leidglich Stützfüße, die insbesondere ausfahrbar ausgebildet sind, um Bodenunebenheiten ausgleichen zu können. Um die Kippsicherheit zu erhöhen, umfasst die Stützkonstruktion vorzugsweise zusätzliche Stabilisierungselemente, wie z.B. seitlich ausfahrbare Pratzen.The stationary device according to the invention has a stationary, in particular frame-shaped support structure which carries or supports a carrying element with fastening means for detachably fastening the attachment. The stationary design of the frame means that the device has no traction drive. Preferably, the device according to the invention also does not include a fixed chassis, such as a caterpillar chassis or wheels. For support on the ground, the support structure preferably comprises only support feet, which are in particular designed to be extendable in order to be able to compensate for uneven floors. In order to increase the security against tipping, the Support structure preferably additional stabilizing elements, such as laterally extendable claws.

Für die Ortsverlegung benötigt die erfindungsgemäße Vorrichtung ein gesondertes Transportfahrzeug. Da die Vorrichtung relativ kleinbauend ausgeführt werden kann, ist der Transport jedoch mit herkömmlichen Transportfahrzeugen möglich, die auf einem Abbruchfeld oder eine Baustelle ohnehin verfügbar sind. Der Transportaufwand ist hierbei wesentlich geringer als im Falle von herkömmlichen stationären Brechanlagen, die mit Rücksicht auf ihre im Vergleich zu Anbaugeräten höhere Produktionskapazität großbauend sind und in der Regel nur mit Sondertransporten oder im zerlegten oder teilzerlegten Zustand transportiert werden können.The device according to the invention requires a separate transport vehicle for the relocation. However, since the device can be made relatively small, it can be transported using conventional transport vehicles which are available in any case on a demolition field or a construction site. The transport costs are significantly lower than in the case of conventional stationary crushing plants, which are large in view of their higher production capacity compared to attachments and can usually only be transported with special transport or in a dismantled or partially dismantled state.

Um das Anbaugerät an der erfindungsgemäßen Vorrichtung in ähnlicher Weise benutzen zu können wie auf einem Baggerarm, ist das Tragelement für das Anbaugerät relativ zur Stützkonstruktion höhenverstellbar und/oder kippbar angeordnet. Die Höhenverstellbarkeit ermöglicht die Einstellung des Abstand des Anbaugeräts zum Boden oder zu einem darunter platzierten Förderband. Durch die Höhenverstellbarkeit wird das bei fix verbauten Aggregaten bekannte Problem des zu geringen Abstandes zwischen Auslauf und Förderband insbesondere im Recycling von stahlarmiertem Beton vermieden. Des weiteren kann das Anbaugerät auf Grund der Höhenverstellbarkeit auch weit nach unten verfahren werden, um bei geringen Raumhöhen (wie etwa im Tunnelbau) eine sehr geringe Aufgabehöhe zu gewährleisten.In order to be able to use the attachment on the device according to the invention in a similar way as on an excavator arm, the support element for the attachment is arranged so that it can be adjusted in height and/or tilted relative to the support structure. The height adjustability allows you to adjust the distance of the attachment to the ground or to a conveyor belt placed below. The height adjustability avoids the problem with permanently installed aggregates of too small a distance between the outlet and the conveyor belt, especially in the recycling of steel-reinforced concrete. Furthermore, due to the height adjustability, the attachment can also be moved far down in order to ensure a very low loading height in the case of low room heights (e.g. in tunnel construction).

Die Kippfunktion des Tragelements ermöglicht ein rasches Entleeren des Anbaugerätes entweder zum Ausschütten unbrechbaren Materials oder von abgesiebtem Überkorn. Die ebenfalls bei fix montierten Werkzeugen sonst nicht mögliche Rüttelfunktion des Tragelements ermöglicht zudem eine Lockerung des Aufgabematerials und damit eine schnelle Lösung von Blockaden. Dadurch wird eine zusätzliche Produktionssteigerung ermöglicht.The tilting function of the carrying element enables the attachment to be emptied quickly, either for dumping unbreakable material or screened oversize grain. The vibrating function of the carrying element, which is also otherwise not possible with permanently mounted tools, also enables the feed material to be loosened and blockages to be solved quickly. This enables an additional increase in production.

Die erfindungsgemäße Vorrichtung zeichnet sich weiters durch eine integrierte Antriebseinrichtung für das Anbaugerät aus, welche über Kupplungs- und/oder Verbindungsmittel in antriebsmäßige Verbindung mit einem Antrieb des Anbaugeräts bringbar ist. Somit wird auch hinsichtlich des Antriebs ein Einsatz des Anbaugeräts ähnlich wie am Ausleger eines Baggers oder dgl. ermöglicht, d.h. es wird die Verwendung von herkömmlichen Anbaugeräten ermöglicht, die eine externe Energiezufuhr benötigen, um angetrieben werden zu können. Das jeweilige Anbaugerät wird somit von dem Energiesystem der erfindungsgemäßen Vorrichtung gespeist. Das Anbaugerät umfasst z.B. einen Hydraulikmotor, der von einem Hydrauliksystem der erfindungsgemäßen Vorrichtung gespeist wird, wobei die entsprechenden Schläuche für den Ölzu- und -ablauf direkt mit dem Anbaugerät verbunden werden.The device according to the invention is further characterized by an integrated drive device for the attachment, which can be brought into drive connection with a drive of the attachment via coupling and/or connecting means. With regard to the drive, the attachment can therefore be used in a manner similar to that on the boom of an excavator or the like, i.e. the use of conventional attachments that require an external energy supply in order to be able to be driven is made possible. The respective attachment is thus fed by the energy system of the device according to the invention. The attachment comprises, for example, a hydraulic motor fed by a hydraulic system of the device according to the invention, the relevant hoses for the oil inlet and outlet being connected directly to the attachment.

Unter einem Anbaugerät wird im Rahmen der vorliegenden Erfindung ein Zusatzwerkzeug für Baumaschinen verstanden, mit dem die Baumaschine verschiedenartige Arbeitsvorgänge ausführen kann. Anbaugeräte sind in der Regel händisch oder mit Hilfe von Schnellwechseleinrichtungen ohne großen Aufwand an die jeweilige Baumaschine, insbesondere deren Auslegerarm, an- und von dieser abbaubar. Das Anbaugerät ist hierbei bevorzugt als Löffelbrecher, insbesondere Löffelbackenbrecher, oder als Sieblöffel ausgebildet.Within the scope of the present invention, an attachment is understood to mean an additional tool for construction machines, with which the construction machine can carry out various types of work processes. Attachments can usually be attached to and removed from the respective construction machine, in particular its extension arm, manually or with the aid of quick-change devices without great effort. The attachment is preferably designed as a spoon crusher, in particular a spoon jaw crusher, or as a sieve spoon.

In einer bevorzugten Ausführungsform der Erfindung wird die Höhenverstellbarkeit bzw. die Kippbarkeit des Anbaugeräts dadurch erreicht, dass das Tragelement für das Anbaugerät an einem an der Stützkonstruktion abgestützten Ausleger angeordnet ist, wobei der Ausleger derart verstellbar ausgebildet ist, dass das Tragelement höhenverstellbar und/oder kippbar ist. Insbesondere umfasst der Ausleger wenigstens einen ersten und einen zweiten Arm, die relativ zueinander schwenkbar sind, wobei vorzugsweise der erste Arm schwenkbar an der Stützkonstruktion befestigt ist. Es ergibt sich somit eine Konstruktion aus zwei Auslegerarmen, die vergleichbar ist mit dem Ausleger eines Baggers. Die beiden Arme sind hierbei bevorzugt schwenkbar angeordnet, sodass sich eine Kinematik ergibt, mit welcher das Tragelement und das daran befestigte Anbaugerät zweidimensional bewegt werden kann, insbesondere in einer senkrechten Ebene, nämlich einer Längsmittelebene der Vorrichtung. Das Anbaugerät kann dadurch in Höhenrichtung bewegt werden und in einer Richtung quer dazu, nämlich nach vorne und hinten. Eine seitliche Verstellbarkeit, z.B. durch eine Drehung des Auslegers um eine senkrechte Schwenkachse, wäre ebenfalls denkbar.In a preferred embodiment of the invention, the height adjustability or tiltability of the attachment is achieved in that the support element for the attachment is arranged on a boom supported on the support structure, the boom being adjustable in such a way that the support element is height-adjustable and/or tiltable is. In particular, the jib comprises at least a first and a second arm which are pivotable relative to one another, the first arm preferably being pivotally attached to the support structure. This results in a construction of two cantilever arms that is comparable to the cantilever of an excavator. In this case, the two arms are preferably pivotably arranged, resulting in kinematics with which the support element and the attachment attached thereto can be moved two-dimensionally, in particular in a vertical plane, namely a longitudinal center plane of the device. The attachment can thereby be moved in the height direction and in a direction transverse thereto, namely forwards and backwards. Lateral adjustability, e.g. by rotating the boom about a vertical pivot axis, would also be conceivable.

Um die Kippbarkeit des Anbaugeräts zu ermöglichen, sieht eine bevorzugte Ausbildung vor, dass das Tragelement für das Anbaugerät schwenkbar am zweiten Arm des Auslegers befestigt ist.In order to allow the attachment to be tilted, a preferred embodiment provides that the support element for the attachment is pivotably attached to the second arm of the boom.

Die Konstruktion des Auslegers mit zwei schwenkbaren Armen ist bevorzugt derart gestaltet, dass das am Tragelement befestigte Anbaugerät zwischen einer Betriebsposition und einer Park- bzw. Transportposition bewegt werden kann, wobei die Arme in der Park- bzw. Transportposition in einer zueinander geschwenkten Position angeordnet sind und in der zueinander geschwenkten Position zwischen sich einen Aufnahmeraum für das Anbaugerät bilden. Besonders bevorzugt ist hierbei vorgesehen, dass der zweite Arm und ggf. der erste Arm des Auslegers abgewinkelt ausgebildet ist bzw. sind. Dies ermöglicht es, dass die Arme in der zueinander verschwenkten Park- bzw. Transportposition gemeinsam im Wesentlichen eine U- oder C-Form ausbilden, welche einen Aufnahmequerschnitt für das Anbaugerät ausbildet.The construction of the boom with two pivotable arms is preferably designed in such a way that the support element attached attachment can be moved between an operating position and a parking or transport position, wherein the arms are arranged in the parking or transport position in a mutually pivoted position and in the mutually pivoted position between them form a receiving space for the attachment. Provision is particularly preferably made here for the second arm and, if applicable, the first arm of the extension arm to be angled. This makes it possible for the arms, in the parking or transport position pivoted relative to one another, to essentially form a U or C shape together, which forms a receiving cross section for the attachment.

Die Schwenkantriebe für die Verschwenkung des ersten Arms, des zweiten Arms und/oder des Tragelements umfassen bevorzugt jeweils wenigstens ein hydraulisches Zylinder-Kolben-Aggregat.The swivel drives for swiveling the first arm, the second arm and/or the support element preferably each comprise at least one hydraulic cylinder-piston unit.

Der Transport der Vorrichtung von und zu ihrem Einsatzort erfolgt wie bereits erwähnt mit Hilfe einer gesonderten Transportvorrichtung, wie z.B. einem Transportfahrzeug. Um das Auf- und Abladen der Vorrichtung auf bzw. vom Fahrzeug zu erleichtern, ist bevorzugt vorgesehen, dass an der Stützkonstruktion oder an einem starr mit dieser verbundenen Element wenigstens eine Öse oder ein Haken für das Ergreifen der Vorrichtung mit einem Hakenlift vorgesehen ist. Die Vorrichtung kann dabei wie ein Abrollcontainer ergriffen und auf die Ladefläche eines Transportfahrzuges, insbesondere eines Hakenliftanhängers, gehoben oder gezogen werden. Eine besonders vorteilhafte Ausführung sieht in diesem Zusammenhang vor, dass die Stützkonstruktion bzw. der Stützrahmen der erfindungsgemäßen Vorrichtung als Grundrahmen eines Abrollcontainers ausgebildet ist.As already mentioned, the device is transported from and to its place of use with the aid of a separate transport device, such as a transport vehicle. In order to facilitate the loading and unloading of the device on or from the vehicle, it is preferably provided that at least one eyelet or a hook for grasping the device with a hook lift is provided on the support structure or on an element rigidly connected to it. The device can be gripped like a roll-off container and lifted or pulled onto the loading area of a transport vehicle, in particular a hook-lift trailer. A particularly advantageous embodiment provides in this context that the support structure or the support frame device according to the invention is designed as a base frame of a roll-off container.

Der Transport der Vorrichtung ist somit in einfacher und kostengünstiger Weise möglich. Der bei mobilen Raupenbrechern oder Raupensieben sonst notwendige Sondertransport von Raupenbrechern oder Raupensieben mittels Tiefladeranhänger wird dadurch vermieden. Solche mobilen Brecher oder Siebeinrichtungen sind zwar mobil ausgeführt, sodass sie sich innerhalb einer Baustelle mit ihrem eigenen Antrieb bewegen können. Über größere Strecken müssen sie aber mit den genannten Sondertransportfahrzeugen befördert werden.The transport of the device is thus possible in a simple and cost-effective manner. This avoids the special transport of crawler crushers or crawler screens that is otherwise necessary with mobile crawler crushers or crawler screens using a low-loader trailer. Such mobile crushers or screening devices are designed to be mobile, so that they can move within a construction site with their own drive. Over longer distances, however, they have to be transported with the special transport vehicles mentioned.

Ein einfacher und schneller Anbau des Anbaugeräts wird vorzugsweise dadurch ermöglicht, dass das Tragelement eine Adapterplatte eines Schnellwechslersystems für Anbaugeräte umfasst. Ein Schnellwechslersystem stellt dabei eine standardisierte Anbauschnittstelle zur Verfügung, wobei die Adapterplatte bevorzugt zur Aufnahme von zwei parallelen Bolzen des Anbaugeräts ausgebildet ist, wobei der Ausleger in der Regel am vorderen Bolzen des Schnellwechslers und der Kippzylinder direkt am hinteren Bolzen angreift.A simple and quick attachment of the attachment is preferably made possible in that the support element comprises an adapter plate of a quick-change system for attachments. A quick coupler system provides a standardized attachment interface, with the adapter plate preferably being designed to accommodate two parallel bolts of the attachment, with the boom usually acting on the front bolt of the quick coupler and the tilting cylinder acting directly on the rear bolt.

Eine bevorzugte Ausbildung sieht vor, dass die Antriebseinrichtung eine vorzugsweise von einem ersten Elektromotor angetriebene, erste Hydraulikpumpe umfasst, die zur Ausbildung eines ersten Hydraulikkreislaufs mit einer zu einem Hydraulikmotor des Anbaugeräts hinführenden Hydraulikleitung und einer vom Hydraulikmotor zurückführenden Hydraulikleitung verbunden ist, wobei die hin- und die rückführende Hydraulikleitung vorzugsweise jeweils ein Anschlussstück zum Anschließen an das Anbaugerät aufweist.A preferred embodiment provides that the drive device comprises a first hydraulic pump, preferably driven by a first electric motor, which is connected to a hydraulic line leading to a hydraulic motor of the attachment and a hydraulic line leading back from the hydraulic motor to form a first hydraulic circuit, with the outward and the returning hydraulic line preferably each has a connector for connecting to the attachment.

Mit einer geeigneten Ventilanordnung am Hydraulikblock der Vorrichtung kann die jeweils gewünschte Drehrichtung des Hydraulikmotor gewählt werden. Beispielsweise kann eine bewegbare Backe bzw. Brechplatte eines Backenbrechers in die eine Drehrichtung für den normalen Brechbetrieb angetrieben werden und die andere Drehrichtung kann für das Lockern von im Brechereinlauf blockierten Materials verwendet werden. Ebenso kann dadurch bei Siebschaufeln bzw. Schaufelseparatoren die Drehrichtung der Sieb- bzw. Brechrotoren geändert werden, um ein effizientes Aussieben zu gewährleisten bzw. Blockaden zu lösen.With a suitable valve arrangement on the hydraulic block of the device, the desired direction of rotation of the hydraulic motor can be selected. For example, a movable jaw or crushing plate of a jaw crusher can be driven in one direction of rotation for normal crushing operation and the other direction of rotation can be used to loosen material blocked in the crusher inlet. The direction of rotation of the sieve or crushing rotors can also be changed in the case of sieve shovels or shovel separators in order to ensure efficient sieving or to remove blockages.

Weiters kann eine vorzugsweise von einem zweiten Elektromotor angetriebene, zweite Hydraulikpumpe vorgesehen sein, welche eine Antriebseinrichtung für die Höhenverstellbarkeit bzw. Kippbarkeit des Tragelements, insbesondere die hydraulischen Zylinder-Kolben-Aggregate der Schwenk- bzw. Kippantriebe, und ggf. einen Hydraulikölkühler zum Kühlen des im ersten Hydraulikkreislauf fließenden Mediums speist.Furthermore, a second hydraulic pump, preferably driven by a second electric motor, can be provided, which has a drive device for the height adjustability or tiltability of the support element, in particular the hydraulic cylinder-piston units of the swivel or tilt drives, and if necessary a hydraulic oil cooler for cooling the fed by the medium flowing in the first hydraulic circuit.

Die Steuerung der erfindungsgemäßen Vorrichtung durch einen Operator erfolgt vorzugsweise nicht durch Betätigungsvorgänge des Operators an der Vorrichtung selbst, sondern ferngesteuert. Die Ausbildung ist zu diesem Zweck bevorzugt so getroffen, dass die Antriebseinrichtung für das Anbaugerät und/oder eine Antriebseinrichtung für die Höhenverstellbarkeit bzw. Kippbarkeit des Tragelements mit einer fernsteuerbaren Steuereinrichtung verbunden sind.The control of the device according to the invention by an operator is preferably not carried out by the operator operating the device itself, but by remote control. For this purpose, the design is preferably such that the drive device for the attachment and/or a drive device for the height adjustability or tiltability of the support element are connected to a remote-controllable control device.

Gemäß einem weiteren Aspekt sieht die Erfindung die Verwendung eines Anbaugeräts an einem Ausleger einer stationären Vorrichtung nach dem ersten Aspekt der Erfindung zum Aufbereiten, insbesondere Zerkleinern, Klassieren und/oder Sortieren, von stückigem Aufgabegut vor.According to a further aspect, the invention provides the use of an attachment on a boom of a stationary device according to the first aspect of the invention for processing, in particular crushing, classifying and/or sorting, of lumpy feed material.

Gemäß einem weiteren Aspekt betrifft die Erfindung die Verwendung einer erfindungsgemäßen Vorrichtung zur Aufnahme und zum Antrieb eines als Anbaugerät ausgebildeten Aggregats, das zum Aufbereiten, insbesondere Zerkleinern, Klassieren und/oder Sortieren, von stückigem Aufgabegut geeignet ist und lösbar am Tragelement des Auslegers befestigt ist.According to a further aspect, the invention relates to the use of a device according to the invention for receiving and driving a unit designed as an attachment, which is suitable for processing, in particular crushing, classifying and/or sorting, lumpy feed material and is detachably attached to the support element of the boom.

Das Anbaugerät ist dabei vorzugsweise als Löffelbrecher, insbesondere Löffelbackenbrecher, oder als Sieblöffel ausgebildet.The attachment is preferably designed as a spoon crusher, in particular a spoon jaw crusher, or as a sieve bucket.

Die Erfindung wird nachfolgend anhand von in der Zeichnung schematisch dargestellten Ausführungsbeispielen näher erläutert. In dieser zeigen Fig. 1 eine perspektivische Darstellung einer erfindungsgemäßen Vorrichtung mit angebautem Löffelbrecher in einer Betriebsposition, Fig. 2 eine Seitenansicht der Vorrichtung gemäß Fig. 1 in der Betriebsposition, Fig. 3 eine Seitenansicht der Vorrichtung gemäß Fig. 1 in einer anderen Betriebsposition, Fig. 4 eine Seitenansicht der Vorrichtung gemäß Fig. 1 in der Parkposition, Fig. 5 eine perspektivische Ansicht der Vorrichtung mit zugeordneter Abfördereinrichtung und Fig. 6 eine Detailansicht des als Löffelbackenbrecher ausgebildeten Löffelbrechers.The invention is explained in more detail below with reference to exemplary embodiments shown schematically in the drawing. in this show 1 a perspective view of a device according to the invention with an attached spoon crusher in an operating position, 2 a side view of the device according to FIG 1 in the operating position, 3 a side view of the device according to FIG 1 in another operating position, 4 a side view of the device according to FIG 1 in the parking position, figure 5 a perspective view of the device with associated discharge device and 6 a detailed view of the spoon crusher designed as a spoon jaw crusher.

In Fig. 1 ist die erfindungsgemäße Vorrichtung dargestellt, die der Aufnahme und dem Antrieb eines Anbaugeräts dient. Das Anbaugerät ist im vorliegenden Ausführungsbeispiel als Löffelbrecher 1 ausgebildet. Der Löffelbrecher 1 ist ein Brechaggregat, das zum Anbauen an einen Auslegerarm einer mobilen Arbeitsmaschine, wie z.B. eines Baggers oder dgl. vorgesehen ist und daher einen Löffel 2 aufweist, mit welchem das zu brechende Material vom Boden oder einem Materialhaufen aufgenommen werden kann. Dadurch gelangt das zu brechende Material in die Aufnahmeöffnung 3 und wird in der Betriebsstellung des Löffelbrechers durch ein integriertes Brechwerk zerkleinert. Das zerkleinerte Material wird an der dem Löffel gegenüberliegenden Seite 4 ausgetragen.In 1 the device according to the invention is shown, which serves to accommodate and drive an attachment. The attachment is designed as a bucket crusher 1 in the present embodiment. The bucket crusher 1 is a crushing unit that is intended for attachment to a boom arm of a mobile working machine, such as an excavator or the like, and therefore has a bucket 2 with which the material to be crushed can be picked up from the ground or a pile of material. As a result, the material to be crushed enters the receiving opening 3 and is crushed by an integrated crushing mechanism when the bucket crusher is in the operating position. The crushed material is discharged on the side 4 opposite the bucket.

Im Anwendungsfall der Erfindung wird der Löffelbrecher nun nicht am Auslegerarm eines mobilen Baufahrzeugs verwendet, sondern an der stationären Vorrichtung 5. Die Materialaufnahme erfolgt dabei nicht dadurch, dass der Löffelbrecher das Material am Boden aufnimmt, sondern mit Hilfe eines gesonderten Fahrzeugs, wie z.B. einem Bagger oder dgl., der das Material aufnimmt und der Aufnahmeöffnung 3 des Löffelbrechers 1 aufgibt, sodass der Löffelbrecher 1 ständig in der in Fig. 1 dargestellten Betriebsposition verbleiben kann. Der Brechbetrieb muss für die Materialaufnahme somit nicht unterbrochen werden.In the application of the invention, the bucket crusher is not used on the boom arm of a mobile construction vehicle, but on the stationary device 5. The material is not picked up by the bucket crusher picking up the material on the ground, but with the help of a separate vehicle, such as an excavator or the like, which receives the material and delivers it to the receiving port 3 of the spoon crusher 1, so that the spoon crusher 1 is always in the in 1 shown operating position can remain. The crushing operation therefore does not have to be interrupted to collect the material.

Die Vorrichtung 5 ist als stationäre Einrichtung ausgebildet und umfasst einen Stützrahmen 6, welcher das tragende Element der Vorrichtung ausbildet und am Boden aufliegt. Der Stützrahmen kann zu diesem Zweck Stützfüße oder dgl. umfassen. Im vorliegenden Ausführungsbeispiel umfasst der Stützrahmen zwei parallele, in Längsrichtung verlaufende Holme 7, die vorne durch einen Querträger 8 miteinander verbunden sind. Im Bereich des Querträgers 8 umfasst der Stützrahmen 6 zwei seitlich ausfahr- oder ausklappbare Pratzen 9, die der Erhöhung der Kippstabilität dienen.The device 5 is designed as a stationary device and includes a support frame 6, which forms the supporting element of the device and rests on the ground. The support frame can include support feet or the like for this purpose. In the present embodiment, the support frame comprises two parallel, in the longitudinal direction running beams 7, which are connected to each other by a cross member 8 at the front. In the area of the cross member 8, the support frame 6 includes two laterally extendable or foldable claws 9, which serve to increase the tipping stability.

Am Stützrahmen 6 ist ein Ausleger 10 befestigt, der einen ersten Arm 11 und einen zweiten Arm 12 umfasst. Der erste Arm 11 ist mittels eines Schwenklagers 13 schwenkbar am Stützrahmen 6 befestigt, wobei die Schwenkachse des Schwenklagers 13 horizontal und im rechten Winkel zur Längsrichtung verläuft. Der Schwenkantrieb für den ersten Arm 11 umfasst ein hydraulisches Zylinder-Kolben-Aggregat 14. Der zweie Arm 12 ist schwenkbar am ersten Arm 11 befestigt, wobei die Schwenkachse parallel zur Schwenkachse des Schwenklagers 13 verläuft. Der Schwenkantrieb für den zweiten Arm 12 umfasst ein hydraulisches Zylinder-Kolben-Aggregat 15. Der zweite Arm ist abgewinkelt ausgebildet und trägt an seinem freien Ende ein Tragelement 16, das z.B. als Adapterplatte eines Schnellwechslersystems für Anbaugeräte ausgebildet ist. das Tragelement 16 ist relativ zum zweiten Arm 12 schwenkbar gelagert, wobei die Schwenkachse wiederum parallel zur Schwenkachse des Schwenklagers 13 verläuft. Der Kippantrieb zum Kippen des Tragelements sowie des daran starr befestigten Löffelbrechers 1 ist mit 17 bezeichnet und als hydraulisches Zylinder-Kolben-Aggregat ausgebildet. Wie besser in Fig. 2 erkennbar ist, ist der Löffelbrecher 1 mit Hilfe von zwei Bolzen 18 an der Adapterplatte 16 befestigt.A boom 10 is fastened to the support frame 6 and comprises a first arm 11 and a second arm 12 . The first arm 11 is pivotally attached to the support frame 6 by means of a pivot bearing 13, the pivot axis of the pivot bearing 13 being horizontal and at right angles to the longitudinal direction. The pivoting drive for the first arm 11 comprises a hydraulic cylinder-piston unit 14. The second arm 12 is pivotably attached to the first arm 11, with the pivot axis running parallel to the pivot axis of the pivot bearing 13. The pivoting drive for the second arm 12 includes a hydraulic cylinder-piston unit 15. The second arm is angled and carries a support element 16 at its free end, which is designed, for example, as an adapter plate of a quick-change system for attachments. the support element 16 is mounted pivotably relative to the second arm 12 , the pivot axis in turn running parallel to the pivot axis of the pivot bearing 13 . The tilting drive for tilting the support element and the spoon crusher 1 rigidly attached to it is denoted by 17 and is designed as a hydraulic cylinder-piston unit. How better in 2 As can be seen, the spoon crusher 1 is fastened to the adapter plate 16 with the aid of two bolts 18 .

Die Vorrichtung 5 weist im hinteren Bereich ein Gehäuse 19 auf, in dem die Antriebseinrichtung zum Antrieb des Löffelbrechers 1 sowie der hydraulischen Zylinder-Kolben-Aggregate 14, 15 und 17 angeordnet ist.The device 5 has a housing 19 in the rear area, in which the drive device for driving the Spoon crusher 1 and the hydraulic cylinder-piston units 14, 15 and 17 is arranged.

In der Seitenansicht gemäß Fig. 2 ist die Vorrichtung 5 so wie in Fig. 1 in einer Betriebsstellung dargestellt, wobei gleiche Teile mit denselben Bezugszeichen versehen sind. Im Unterschied zu Fig. 1 ist eine klappbare Plattform 20 im nach unten aufgeklappten Zustand dargestellt. Die klappbare Plattform 20 ist vorgesehen, um allenfalls Gewichte für eine erhöhte Stabilität bei schwereren Anbaugeräten platzieren zu können.In the side view according to 2 the device 5 is as in 1 shown in an operating position, with the same parts being provided with the same reference numbers. In contrast to 1 a foldable platform 20 is shown in the folded-down state. The foldable platform 20 is provided in order to be able to place any weights for increased stability with heavier attachments.

Durch geeignete Betätigung der hydraulischen Zylinder-Kolben-Aggregate 14 und 15 kann der Löffelbrecher 1 in Richtung des Doppelpfeils 21 in der Höhe verstellt werden. Mit Hilfe des hydraulischen Zylinder-Kolben-Aggregats 17 kann der Löffelbrecher im Bedarfsfall gekippt werden.The bucket crusher 1 can be adjusted in height in the direction of the double arrow 21 by suitably actuating the hydraulic cylinder-piston units 14 and 15 . With the help of the hydraulic cylinder-piston unit 17, the bucket crusher can be tilted if necessary.

In Fig. 3 ist der Ausleger 10 in einer weiter nach vorne verlagerten Stellung gezeigt, wobei der Löffelbrecher 1 gekippt wurde, sodass ggf. in der Brecheinrichtung des Löffelbrechers 1 verbleibendes Material, wie schematisch mit dem Pfeil 22 angedeutet, ausgetragen werden kann.In 3 the boom 10 is shown in a position shifted further forward, with the bucket crusher 1 being tilted so that any material remaining in the crushing device of the bucket crusher 1 can be discharged, as indicated schematically by the arrow 22 .

In Fig. 4 ist der Löffelbrecher 1 in der Parkstellung dargestellt, in welcher der Ausleger 10 eingeklappt ist und die Auslegerarme 11 und 12 gemeinsam ein C- bzw. U-förmiges Aufnahmeprofil ausbilden, in dem der Löffelbrecher 1 angeordnet ist. Die Vorrichtung 5 kann in dieser Stellung in einfacher Weise auf ein Transportfahrzeug verbracht werden und es kann ein Ortswechsel vorgenommen werden. Weiters ist in Fig. 4 ein Haken 29 zur Aufnahme an einen nicht dargestellten Hakenlifthänger ersichtlich.In 4 the bucket crusher 1 is shown in the parking position, in which the boom 10 is folded in and the boom arms 11 and 12 together form a C or U-shaped receiving profile in which the bucket crusher 1 is arranged. In this position, the device 5 can easily be placed on a transport vehicle and the location can be changed. Next is in 4 a hook 29 for attachment to a hook lift trailer, not shown, can be seen.

In Fig. 5 ist der Löffelbrecher 5 wieder in der Betriebsstellung gezeigt, wobei das gebrochene Material, das an der Unterseite 4 austritt auf eine Fördereinrichtung 23 ausgebracht wird. Die Fördereinrichtung 23 umfasst dabei einen direkt unterhalb der Materialausbringung des Löffelbrechers 1 angeordneten Materialbunker 24, von dem das Material mit Hilfe des Förderbandes 25 abtransportiert wird.In figure 5 the spoon crusher 5 is again shown in the operating position, with the crushed material that exits at the bottom 4 being discharged onto a conveyor 23 . The conveying device 23 comprises a material bunker 24 which is arranged directly below the material output of the spoon crusher 1 and from which the material is transported away with the aid of the conveyor belt 25 .

Fig. 6 zeigt einen Backenbrecherlöffel im Schnitt, wobei eine unbewegliche erste Brecherbacke 25 und eine dieser gegenüberliegende bewegliche Brecherbacke 26 vorgesehen sind. Die Brecherbacke 26 wird von einem Exzenterantrieb 27 zu einer pendelnden Hin- und Herbewegung angetrieben, sodass zwischen die Backen 25 und 26 gelangendes Material gebrochen wird. Das gebrochenen Material bewegt sich in Richtung des Spalts 28 und kann ausgetragen werden. 6 shows a jaw crusher spoon in section, with a stationary first crusher jaw 25 and a movable crusher jaw 26 lying opposite thereto being provided.
