Die Erfindung betrifft eine mobile Bodenaufbereitungsanlage in Form einer auf einem Containerfahrzeug aufsetzbaren Kompaktanlage mit einem Bodengestell, aufweisend einen an einem Ende der Kompaktanlage befindlichen Aufgabebunker sowie ein unter dem Aufgabebunker mit einer in Längsrichtung der Kompaktanlage zu deren Mittelpunkt gerichteten Förderrichtung ausgelegten Abzugsband, ferner aufweisend eine sich unterhalb des Abzugsbandes in Richtung des liunkerseitigen Endes der Kompaktanlage erstreckende, geneigte Siebeinrichtung mit einer Rutsche zum Austrag ausgehaltenen Überkorns, sowie aufweisend ein unterhalb der Siebeinrichtung angeordnetes und sich vom Ende der Siebeinrichtung über die Längsrichtung der Kompaktanlage bis zu einem dem Aufgabebunker benachbart angeordneten Mischer ansteigend erstreckendes und an seinem zugeordneten Ende an einen Materialeinlauf für den Mischer angeschlossenes Transportband, wobei an dem Transportband eine Bandwaage eingerichtet und oberhalb des Transportbandes wenigstens ein Bunker zur geregelten Zugabe eines Zuschlagstoffes angeordnet ist.The invention relates to a mobile soil preparation plant in the form of a compact vehicle mounted on a container system with a bottom frame, comprising a feed bunker located at one end of the compact system and under the task bunker with a directed in the longitudinal direction of the compact system to the center conveying direction discharge tape, further comprising a below the take-off belt in the direction of the hopper side end of the compact plant extending, inclined screen means with a chute for discharge surviving oversize, and having an arranged below the sieve and from the end of the sieve over the longitudinal direction of the compact system up to a task bunker adjacent arranged mixer rising extending and at its associated end to a material inlet for the mixer connected conveyor belt, wherein on the conveyor belt a belt scale set up and above the Tr ansportbandes at least one bunker for the regulated addition of an aggregate is arranged.

Eine Bodenaufbereitungsanlage mit den vorgenannten Merkmalen ist in der als nächstliegendem Stand der Technik angesehenen EP 1 317 969 A1 beschrieben. Die bekannte Kompaktanlage beinhaltet die für die Bodenaufbereitungsanlage erforderlichen Aggregate, die gemeinsam auf einem Bodengestell angeordnet und derart einander zugeordnet sind, dass sich ein Durchflussweg für das Material durch die Kompaktanlage ergibt. Soweit das Material am Ende des Durchflussweges in einen Mischer verbracht und dort mit Zuschlagstoffen gemischt wird, ist ein Abzug des Materials aus dem Mischer und Abförderung nach außerhalb der Kompaktanlage nicht vorgesehen.A soil treatment plant having the aforementioned features is considered as the closest prior art EP 1 317 969 A1 described. The known compact system includes the required for the soil preparation plant units, which are arranged together on a floor frame and associated with each other such that there is a flow path for the material through the compact system. So far the material is spent at the end of the flow path in a mixer and mixed there with aggregates, a deduction of the material from the mixer and discharge to outside the compact system is not provided.

Der Erfindung liegt daher die Aufgabe zugrunde, eine mobile Bodenaufbereitungs-Kompaktanlage mit den gattungsgemäßen Merkmalen so einzurichten, dass die Anlage Kompakt aufgebaut und leicht zwischen unterschiedlichen Einsatzorten umsetzbar ist.The invention is therefore based on the object, a mobile ground conditioning compact system with the generic features set up so that the system is compact and easy to implement between different sites.

Die Lösung dieser Aufgabe ergibt sich aus dem Anspruch 1; vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.The solution to this problem arises from the claim 1; advantageous embodiments and modifications of the invention are specified in the dependent claims.

Die Erfindung sieht in ihrem Grundgedanken vor, dass die Siebeinrichtung mit Rutsche am bunkerseitigen Ende der Kompaktanlage angeordnet sind und dass innerhalb des Bodengestells ein unterhalb des Mischers verlaufendes Produktband mit einem zum dem Aufgabebunker entgegengesetzten Ende der Kompaktanlage weisenden Abwurfkopf angeordnet ist, wobei der nach außen weisende Abwurfkopf des Produktbandes längsverschiebbar ist derart, dass in der ausgeschobenen Stellung der Abwurfkopf nach außerhalb der Kompaktanlage ragt.The invention provides in its basic idea that the screening device with slide at bunkerseitigen end of the compact system are arranged and that within the bottom frame extending below the mixer product band is arranged with an opposite end of the task bunker the compact system facing discharge head, said outwardly facing Discharge head of the product tape is longitudinally displaceable such that in the extended position of the discharge head protrudes to the outside of the compact system.

Mit der Erfindung ist der Vorteil verbunden, dass aufgrund der Anordnung der einzelnen Aggregate zueinander eine kompakte Bodenaufbereitungsanlage geschaffen ist, deren Abmessungen die Abmessungen eines üblichen Containers nicht übersteigt, so dass die Kompaktanlage auf einen LKW aufgesetzt und somit als solche über die Strasse transportiert werden kann. Im Rahmen der erfindungsgemäßen Ausgestaltung sind Vorkehrungen hinsichtlich der Ausbildung der einzelnen Aggregate und deren Steuerung getroffen, so dass an unterschiedlichen Stellen der Aufbereitungsanlage Einflussnahmen auf den Verfahrensablauf möglich sind.With the invention has the advantage that due to the arrangement of the individual units to each other a compact soil treatment plant is created whose dimensions do not exceed the dimensions of a conventional container, so that the compact system can be placed on a truck and thus transported as such on the street , In the context of the embodiment according to the invention provision is made with regard to the formation of the individual units and their control, so that at different points of the treatment plant influencing the process flow are possible.

Der kompakte Aufbau auf der Grundfläche eines Containers wird zunächst dadurch sichergestellt, dass der Aufgabebunker gegenüber dem Bodensockel der Kompaktanlage soweit angehoben ist, dass unterhalb des Aufgabebunkers sowohl ein Abzugsband als auch eine vorzugsweise mehrstufige Siebeinrichtung angeordnet werden kann. Um die Längserstreckung dieser Aggregate zu begrenzen, ist vorgesehen, dass die Förderrichtung des Abzugsbandes zum Mittelpunkt der Anlage gerichtet und die Förderrichtung der Siebeinrichtung wiederum entgegengesetzt dazu eingerichtet ist, so dass sich das aufzubereitende Material am Ende der Siebeinrichtung wieder am Ende der Kompaktanlage befindet und insoweit für die weitere Materialführung wieder die gesamte Länge der Kompäktanlage beziehungsweise des Containers zur Verfügung steht. Dies gibt auch die Möglichkeit, das ausgehaltene Überkorn am Ende der Kompaktanlage über die zugeordnete Rutsche abzuwerfen. In dem dem Aufgabebunker mit dem darunter liegenden Abzugsband und der Siebeinrichtung benachbarten vorderen Teil der Kompaktanlage ist ein Mischer mit einer an sich aus der DE 202 10 667.5 U1 bekannten Ausbildung aufgestellt. Ein sich diagonal zwischen dem Ende der Siebeinrichtung und dem Materialeinlauf des Mischers erstreckendes Transportband überbrückt auch den Höhenunterschied, wobei dem Transportband wenigstens ein Bunker zugeordnet ist, aus welchem ein Zuschlagstoff der auf dem Transportband liegenden Materialschicht zugesetzt werden kann. Der Mischer ist seinerseits soweit von der Bodenebene der Kompaktanlage hoch gesetzt, dass unterhalb des Mischers noch ein Produktband angeordnet ist, über welches das aufbereitete Material aus der Kompaktanlage austragbar ist.The compact construction on the base of a container is first ensured by the fact that the task bunker is raised relative to the bottom base of the compact system so far that both a discharge belt and a preferably multi-stage screening device can be arranged below the task bunker. In order to limit the longitudinal extent of these units, it is provided that the conveying direction of the discharge belt directed to the center of the system and the conveying direction of the screening device is in turn set opposite thereto, so that the material to be processed at the end of the screening device is again at the end of the compact system and insofar the entire length of the Kompäktanlage or the container is available for further material management again. This also gives the possibility of dropping the over-grain at the end of the compact system via the assigned chute. In the task bunker with the underlying discharge belt and the screen device adjacent the front part of the compact system is a mixer with a per se from the DE 202 10 667.5 U1 established training. A diagonally between the end of the screening device and the material inlet of the Mixer extending conveyor belt also bridges the height difference, wherein the conveyor belt is associated with at least one bunker from which an aggregate of the lying on the conveyor belt material layer can be added. For its part, the mixer is set high enough from the floor level of the compact system that a product band is still arranged below the mixer, via which the processed material can be discharged from the compact system.

Soweit nach einem Ausführungsbeispiel der Erfindung vorgesehen ist, dass der Aufgabebunker auf seinem Umfang mit aufstellbaren Seitenwänden versehen ist, können während des Transports der Kompaktanlage über die Strasse die Seitenwände des Aufgabebunkers eingeklappt werden, so dass während des Transportes Höhe eingespart ist. Im Betrieb werden die Seitenwände hochgestellt, so dass sich eine ausreichende Materialmenge in den Aufgabebunker einwerfen lässt.As far as according to an embodiment of the invention, it is provided that the task bunker is provided on its periphery with deployable side walls, the side walls of the task bunker can be folded during transport of the compact system on the road, so that height is saved during transport. During operation, the side walls are raised so that a sufficient amount of material can be thrown into the feed bunker.

Nach einem Ausführungsbeispiel der Erfindung ist vorgesehen, dass das Abzugsband in seiner Geschwindigkeit regelbar eingerichtet ist; insoweit ist es möglich, die Schichthöhe des auf die nachgeschaltete Siebeinrichtung aufzugebenden Materials einzustellen, um einerseits einen guten Durchsatz zu gewährleisten und andererseits eine Überschüttung der Siebeinrichtung zu vermeiden.According to one embodiment of the invention, it is provided that the take-off belt is adjustable in its speed; In that regard, it is possible to adjust the layer height of the material to be dispensed onto the downstream screening device in order to ensure a good throughput on the one hand and to prevent overflow of the screening device on the other hand.

Soweit nach einem Ausführungsbeispiel die Übergabe am Ende des Abzugsbandes auf die darunter liegende Siebeinrichtung eingehaust ist, ist in vorteilhafter Weise eine Staubentwicklung vermieden.As far as according to one embodiment, the transfer at the end of the draw-off belt is housed on the underlying screening device, dust formation is avoided in an advantageous manner.

Nach einem Ausführungsbeispiel der Erfindung kann vorgesehen sein, dass die Siebeinrichtung aus mehreren hintereinander geschalteten Siebstufen mit unterschiedlichen Siebungsgrößen besteht. In entsprechenden Ausführungsformen kann dabei vorgesehen sein, dass die Siebstufen in Form von Stangensizern und/oder Siebdecks ausgebildet sind, ferner dass die Siebstufen in ihrem Siebwinkel gegen die Horizontale einstellbar sind. Hierbei kann vorgesehen sein, dass der Antrieb für die Siebeinrichtung als Unwuchterreger ausgebildet ist.According to one exemplary embodiment of the invention, it can be provided that the screening device consists of several screening stages connected in series with different screening sizes. In corresponding embodiments, it may be provided that the screening stages in the form of Bar sizers and / or screening decks are formed, further that the screening stages are adjustable in its screen angle against the horizontal. It can be provided that the drive for the screening device is designed as an unbalance exciter.

Soweit es das aufzubereitende Material erfordert, dass unterschiedliche Zuschlagstoffe in den Verfahrensgang einzubringen sind, kann nach einem Ausführungsbeispiel der Erfindung vorgesehen sein, dass oberhalb des Transportbandes mehrere, unterschiedliche Zuschlagsstoffe aufnehmende Bunker angeordnet sind.As far as it requires the material to be processed that different additives are to be introduced into the process, according to one embodiment of the invention may be provided that above the conveyor belt, a plurality of different aggregates receiving bunkers are arranged.

Zusätzlich zu der vorgesehenen, dem Transportband zugeordneten Bandwaage kann vorgesehen sein, dass das Transportband in seiner Geschwindigkeit regelbar eingerichtet ist, so dass die Steuerung der Zugabe des Zuschlagstoffes verbessert ist.In addition to the intended, the conveyor belt associated belt scale can be provided that the conveyor belt is adjustable in its speed, so that the control of the addition of the additive is improved.

Der im Rahmen der Kompaktanlage eingesetzte Mischer ist im Grundsatz aus der DE 202 10 667.5 U1 bekannt. Im einzelnen zeichnet sich dieser Mischer dadurch aus, dass der Mischer zwei in einem Gehäuse parallel zueinander angeordnete Wellen aufweist, wobei an den beiden Wellen jeweils eine Mehrzahl von Mischwerkzeugen pendelnd derart aufgehängt ist, dass sich die Mischwerkzeuge bei Drehung der Welle aufgrund der Fliehkraft nach außen aufstellen, und wobei die Drehrichtung der Wellen gegenläufig zueinander in Richtung des oberhalb der Wellen angeordneten Materialeinlaufes eingestellt ist.The mixer used in the compact system is basically made of DE 202 10 667.5 U1 known. In particular, this mixer is characterized in that the mixer has two shafts arranged parallel to one another in a housing, wherein a plurality of mixing tools is suspended in a pendulum manner on the two shafts in such a way that, as the shaft rotates, the mixing tools move outwards due to the centrifugal force set up, and wherein the direction of rotation of the waves is set in opposite directions in the direction of the above the waves arranged material inlet.

Es kann vorgesehen sein, dass in dem Materialeinlauf des Mischers eine verstellbar gehalterte Leitwand zur Einstellung unterschiedlicher Eintrittsparabeln des in den Mischer geförderten Materials angeordnet ist.It can be provided that in the material inlet of the mixer, an adjustably supported baffle for adjusting different Eintrittsparabeln of the conveyed material in the mixer material is arranged.

Zur Verbesserung des Mischerfolges kann in einer Weiterbildung des bekannten Mischers vorgesehen sein, dass die beiden, die Mischwerkzeuge tragenden Wellen im Gehäuse versetzt zueinander angeordnet sind derart, dass das durch den Materialeinlauf geführte Material von den an der ersten, oberen Welle angeordneten Mischwerkzeugen auf die an der zweiten, unterhalb der ersten Welle angeordneten Welle befindlichen Mischwerkzeuge geworfen wird. Hierdurch wird eine intensivere Durchmischung des Materials erreicht, so dass im Ergebnis geringere Mengen an Zuschlagstoffen eingesetzt zu werden brauchen.To improve the mixer success may be provided in a development of the known mixer that the two shafts carrying the mixing tools are arranged offset from one another in the housing such that the guided through the material inlet material from the arranged on the first, upper shaft mixing tools on the the second, located below the first shaft shaft mixing tools is thrown. As a result, a more intensive mixing of the material is achieved, so that, as a result, smaller quantities of additives need to be used.

Nach einem Ausführungsbeispiel der Erfindung ist vorgesehen, dass in einem Zwischenraum zwischen den durch Fliehkraft aufgestellten Mischwerkzeugen eine parallel zu den Wellen ausgerichtete Homogenisierungsleiste angeordnet ist.According to one exemplary embodiment of the invention, it is provided that a homogenizing strip oriented parallel to the shafts is arranged in a space between the mixing tools set up by centrifugal force.

Zur Verbesserung der Qualität der Bodenaufbereitung kann vorgesehen sein, dass Einrichtungen zur Zugabe von mit Mikroben versetzten Flüssigkeiten im Bereich des Mischers und/oder des Transportbandes und/oder des Produktbandes vorgesehen sind.In order to improve the quality of the soil treatment, it may be provided that facilities for adding microbe-added liquids are provided in the area of the mixer and / or the conveyor belt and / or the product belt.

Es wird vorgesehen , dass der nach außen weisende Abwurfkopf des Produktbandes längsverschiebbar ist derart, dass in der ausgeschobenen Stelle der Abwurfkopf nach außerhalb der Kompaktanlage ragt. Hiermit ist eine leichte Übergabe des aufbereiteten Materials aus der Kompaktanlage auf ein entsprechendes Transportfahrzeug oder auf Maschinen zum Einbringen des aufbereiteten Materials gegeben.It is provided that the outwardly facing discharge head of the product strip is longitudinally displaceable such that in the ejected position of the discharge head protrudes to the outside of the compact system. This is a slight transfer of the processed material from the compact system is given to a corresponding transport vehicle or machinery for introducing the processed material.

Insgesamt ergeben sich im Rahmen der beschriebenen Kompaktanlage zahlreiche Möglichkeiten, auf den Materialfluss in der Kompaktanlage Einfluss zu nehmen und so die Qualität des Aufbereitungsvorganges zu steuern. So erlaubt es die Steuerung der Geschwindigkeit des Bunkerabzugbandes, die Schichthöhe des aufzubereitenden Materials von Beginn an so einzustellen, dass die nachfolgende Siebeinrichtung nicht über Gebühr belastet wird; gleichzeitig wird hier schon die von dem Transportband aufzunehmende Menge im Hinblick auf Zugabe der Zuschlagsstoffe festgelegt bzw. beeinflusst. Soweit im Rahmen der Siebeinrichtung es möglich ist, die einzelnen Siebstufen in ihrem Siebwinkel einstellbar auszubilden, sind die Verweildauern des Materials auf der zugeordneten Siebfläche länger oder kürzer einzustellen.Overall, there are numerous possibilities in the context of the compact system described to influence the material flow in the compact system and thus control the quality of the treatment process. Thus it allows the control of the speed of the Bunkerabzugbandes to adjust the layer height of the material to be processed from the beginning so that the subsequent screening device is not excessively burdened; At the same time, the quantity to be absorbed by the conveyor belt is already defined or influenced with regard to the addition of the additives. Insofar as it is possible within the screening device to make the individual screening stages adjustable in their screen angle, the residence times of the material on the associated screen surface are to be set longer or shorter.

Im Hinblick auf die Zugabe der Zuschlagstoffe auf das Transportband lässt die Erfindung je nach Ausrüstung der Anlage zwei unterschiedliche Betriebszustände zu. Im Rahmen eines manuellen Betriebes, werden die Zuschläge aufgrund einer vorbestimmten Einstellung in Abhängigkeit von dem von der Bandwaage ermittelten Materialfluss zugegeben. Bei Einsatz eines entsprechenden Rechners ist auch ein programmierter Betrieb möglich, bei welchem die Aufgabe des aufzubereitenden Gutes von der Siebeinrichtung auf das in seiner Geschwindigkeit regelbare Transportband erfolgt, bei welchem abhängig von der Schichtdicke des auf dem Transportband liegenden Materials aufgrund der Erfassung der Materialmenge durch die Bandwaage die Zuschlagstoffe automatisch in ihrer Menge korrigiert und kontinuierlich dem Material zugegeben werden. Dabei können die Zuschläge von einem, zwei, drei oder auch noch weiteren Zuschlag-Bunkern zugeführt werden. Die im richtigen Verhältnis zueinander erfolgende Zugabe an Zuschlagsstoffen erfolgt gemäß einem eingerichteten Steuerungsprogramm und ist abgestimmt auf den Durchsatz des aufzubereitenden Materials. Das entsprechende Steuerungsprogramm ist beispielsweise über eine Computer-Schnittstelle veränderbar, und zwar permanent (online) oder auch im Wege eines offline/upload-Betriebes. Im Rahmen der verwendeten Steuerung können auch weitere Parameter an anderen Aggregaten, wie ausgeführt, angesteuert werden. Die Steuerung kann die erfassten Daten beispielsweise auch protokollieren und zur weiteren Datenverarbeitung mittels Datenaustausch (online/up-download) beispielweise an einen externen PC übermitteln.With regard to the addition of the additives to the conveyor belt, the invention allows two different operating conditions depending on the equipment of the system. As part of a manual operation, the supplements are added due to a predetermined setting depending on the material flow determined by the belt weigher. When using a corresponding computer and a programmed operation is possible in which the task of the processed material from the screening device is carried out on the variable in its speed conveyor belt, wherein depending on the layer thickness of the material lying on the conveyor belt due to the detection of the amount of material through the Belt scale, the aggregates are automatically corrected in their quantity and continuously added to the material. The surcharges can be supplied by one, two, three or even further surcharge bunkers. The addition of aggregates in the correct proportion to each other is carried out according to an established control program and is adjusted to the throughput of the material to be processed. The corresponding control program can be changed via a computer interface, for example, permanently (online) or also via an offline / upload operation. As part of the control used, other parameters on other units, as stated, can be controlled. The controller can also log the recorded data, for example, and transmit it to an external PC for further data processing by means of data exchange (online / up-download), for example.
