Description

Die Erfindung betrifft eine Siebmaschine für LKWs mit Hakenliftvorrichtung.The invention relates to a screening machine for trucks with hook lift device.

Siebmaschinen mit angetriebenen Siebförderern zum Sieben und Trennen unterschiedlicher Fraktionen von Abraum, Erdaushub und anderen Materialien sind grundsätzlich bekannt. Derartige Siebmaschinen werden mit Tiefladern an den Einsatzort gebracht. Hierfür vorgesehene Fahrzeuge sind nicht besonders wendig oder geländegängig.Screening machines with powered screen conveyors for screening and separating different fractions of overburden, excavated earth and other materials are known in principle. Such screening machines are brought to the site with low loaders. Vehicles intended for this purpose are not particularly manoeuvrable or off-road.

Grundsätzlich bekannt sind auch LKWs mit Hakenliftvorrichtung, beispielsweise zum Transport von Containern. Ein entsprechend ausgebildeter LKW weist hinter seinem Führerhaus und zum Teil eingelassen in eine Ladefläche einen bewegbaren und mit einem Haken versehenen Transportarm auf, mit dem der Container zum Abladen desselben an einer Stirnseite anhebbar und von der Ladefläche herunter schiebbar ist. Hierzu ist die Ladefläche an ihrem Ende mit Rollen oder Walzen versehen, auf denen sich der Container abstützt. Zugleich weist der Container an seinem rückwärtigen Ende Rollen oder Walzen auf, sodass ein Abrollen auf dem Untergrund möglich ist. Es kann aber auch ein nicht drehbares Stützorgan vorgesehen sein, etwa ein Rohr oder abwärts gerichtete Vorsprünge. Vorzugsweise bei ungünstigem Untergrund wird der LKW vorwärtsbewegt, sobald das Stützorgan des Containers den Untergrund erreicht hat.In principle, trucks with hook lift device, for example for the transport of containers, are also known. A suitably trained truck has behind his cab and partly embedded in a cargo area on a movable and provided with a hook transport arm, with which the container for unloading the same at an end side can be raised and pushed down from the loading area. For this purpose, the loading area is provided at its end with rollers or rollers on which the container is supported. At the same time, the container has at its rear end rollers or rollers, so that rolling on the ground is possible. However, it may also be provided a non-rotatable support member, such as a pipe or downwardly directed projections. Preferably in unfavorable ground, the truck is moved forward as soon as the support member of the container has reached the ground.

Aufgabe der vorliegenden Erfindung ist die Schaffung einer möglichst einfach zu transportierenden und zu verladenden Siebmaschine.The object of the present invention is to provide a screening machine which is as easy to transport and to load as possible.

Zur Lösung der Aufgabe weist die Siebmaschine die Merkmale des Anspruchs 1 auf. Danach ist die Siebmaschine an LKWs mit Hakenliftvorrichtung angepasst und weist hierzu eine Aufnahme für einen Hakenlift an einer Stirnseite und insbesondere mindestens eine Absetzrolle oder andere Stützorgane an der anderen Stirnseite auf. Derartige LKWs sind in der Regel kürzer und geländegängiger als Tieflader. Die erfindungsgemäße Siebmaschine ist deshalb einem breiteren Einsatzbereich zugänglich.To solve the problem, the screening machine on the features of claim 1. Thereafter, the screening machine is adapted to trucks with hook lift device and has for this purpose a receptacle for a hook lift on an end face and in particular at least one Absetzrolle or other supportive organs on the other end face. Such trucks are usually shorter and all-terrain than low loaders. The screening machine according to the invention is therefore accessible to a wider range of applications.

Nach einem weiteren Gedanken der Erfindung weist die Siebmaschine einen Bunker an der Stirnseite der Aufnahme auf, wobei Aufnahme und Bunker aus einer Transportposition in eine Arbeitsposition bewegbar sind - und wieder zurück -, und wobei der Bunker nur in seine Arbeitsposition bewegbar ist, wenn sich die Aufnahme in ihrer Arbeitsposition bzw. nicht in ihrer Transportposition befindet. Mit "Transportposition" ist eine Position für den Transport der Siebmaschine auf dem LKW gemeint. Die Aufnahme für den Hakenlift ist hier zugleich Arretierungsmittel für den Bunker. Der Bunker kann nur dann aus einer Transportposition in die Arbeitsposition bewegt werden, wenn sich die Aufnahme nicht in ihrer Transportposition befindet bzw. wenn die Aufnahme in ihre Arbeitsposition bewegt ist.According to a further aspect of the invention, the screening machine on a bunker on the front side of the receptacle, recording and bunkers are movable from a transport position to a working position - and back again -, and wherein the bunker is movable only in its working position when the Recording in its working position or not in its transport position. By "transport position" is meant a position for the transport of the screening machine on the truck. The attachment for the hook lift is here also locking means for the bunker. The bunker can only be moved from a transport position to the working position when the receptacle is not in its transport position or when the receptacle is moved to its working position.

Vorteilhafterweise beinhaltet die Aufnahme ein klappbares Rahmenteil, welches vorzugsweise mit einer Öse versehen ist, in die ein Haken des Hakenlifts eingreifen kann. Das klappbare Rahmenteil kann als Bügel ausgebildet sein. Die Aufnahme ist insbesondere bewegbar zwischen einer vertikalen Transportposition und einer horizontalen Arbeitsposition. Das horizontal gerichtete Rahmenteil kann dann als Auflage für den Bunker in Arbeitsposition vorgesehen sein. Die Verstellung der Aufnahme kann manuell, hydraulisch oder elektrisch erfolgen. Vorzugsweise ist die Aufnahme in den verschiedenen Positionen mechanisch arretierbar.Advantageously, the receptacle includes a hinged frame part, which is preferably provided with an eyelet into which a hook of the hook lift can engage. The foldable frame part may be formed as a bracket. The receptacle is in particular movable between a vertical transport position and a horizontal working position. The horizontally directed frame part can then be provided as a support for the bunker in working position. The adjustment of the recording can be done manually, hydraulically or electrically. Preferably, the receptacle is mechanically lockable in the various positions.

Nach einem weiteren Gedanken der Erfindung ist der Bunker insbesondere hydraulisch verschiebbar zwischen der Transportposition und der Arbeitsposition. In seiner Arbeitsposition stützt sich der Bunker vorzugsweise zumindest einseitig (stirnseitig) auf der Aufnahme ab. In der Transportposition ist der Platzbedarf (Gesamtlänge) der Siebmaschine am geringsten.According to a further aspect of the invention, the bunker is in particular hydraulically displaceable between the transport position and the working position. In its working position, the bunker is preferably supported on at least one side (frontally) on the recording. In the transport position, the space requirement (total length) of the screening machine is the lowest.

Vorteilhafterweise ist die Siebmaschine als selbstfahrende Maschine ausgebildet, mit Fahrwerk und Antriebsaggregat. Dadurch kann die Siebmaschine auch unabhängig vom LKW bewegt werden. Im Vordergrund steht dabei nicht die Teilnahme am öffentlichen Straßenverkehr, sondern die Bildung langgestreckter Abraumhalden im Betrieb (das sogenannte Mietenziehen). Als Antrieb ist vorzugsweise ein Verbrennungsmotor vorgesehen, ggf. auch in Verbindung mit einer Kombination aus Hydraulikpumpe/Hydraulikmotor oder Generator/Elektromotor.Advantageously, the screening machine is designed as a self-propelled machine, with chassis and drive unit. As a result, the screening machine can also be moved independently of the truck. In the foreground is not the participation in the public road traffic, but the formation of elongated waste dumps in operation (the so-called Mietenziehen). The drive is preferably an internal combustion engine provided, possibly also in conjunction with a combination of hydraulic pump / hydraulic motor or generator / electric motor.

Besonders vorteilhaft ist die Verwendung eines Raupenfahrwerks. Dieses bietet eine gute Lastverteilung (Flächenpressung) und Geländegängigkeit. Möglich ist aber auch die Verwendung eines Räderfahrwerks.Particularly advantageous is the use of a crawler track. This offers a good load distribution (surface pressure) and off-road capability. But it is also possible to use a wheel chassis.

Nach einem weiteren Gedanken der Erfindung ist das Fahrwerk ausfahrbar. Dadurch ist die Höhe der Siebmaschine über dem Untergrund veränderbar. Damit sind zumindest zwei Vorteile verbunden. Zum einen ist die Höhe der Siebmaschine zum Transport auf dem LKW reduzierbar. Die vom Gesetzgeber vorgeschriebene zulässige Gesamthöhe ist so leichter einzuhalten. Außerdem ist ein Anheben der Siebmaschine im Betrieb vorteilhaft zur Erzielung höherer Abwurfkegel. Die Siebmaschine muss dann nicht so oft verfahren werden. Vorteilhafterweise ist das Fahrwerk in Transportposition (Transport durch den LKW) soweit eingefahren, dass kein Kontakt mehr zum Boden besteht oder zumindest nicht mehr die volle Last der Siebmaschine auf dem Fahrwerk ruht. Möglich ist aber auch eine Transportstellung, bei der das Fahrwerk gleichwohl die Siebmaschine trägt, jedoch mit nur einer geringen Bodenfreiheit.According to a further aspect of the invention, the chassis is extendable. As a result, the height of the screening machine above the ground is changeable. This brings at least two advantages. On the one hand, the height of the screening machine can be reduced for transport on the truck. The legal total height required by law is easier to adhere to. In addition, a lifting of the screening machine during operation is advantageous for achieving higher discharge cone. The screening machine then does not have to be moved so often. Advantageously, the landing gear in transport position (transport by the truck) is retracted so far that no contact with the ground exists or at least no longer rest the full load of the screening machine on the chassis. But it is also possible a transport position in which the chassis nevertheless carries the screening machine, but with only a small ground clearance.

Gegenstand der Erfindung ist auch ein Lastkraftfahrzeug (LKW) mit Hakenliftvorrichtung und mit einer Siebmaschine wie zuvor dargestellt.The invention is also a truck (truck) with hook lift device and with a screening machine as previously shown.

Weitere Merkmale der Erfindung ergeben sich aus der Beschreibung im Übrigen und aus den Ansprüchen. Vorteilhafte Ausführungsformen der Erfindung werden nachfolgend anhand von Zeichnungen näher erläutert. Es zeigen:

Eine Siebmaschine 10 weist gemäß Fig. 1 ein schräg aufwärts gerichtetes Sternsieb 11, welches auch ein Scheibensieb sein kann, einen längsgerichteten Bandförderer 12, ein unteres, quergerichtetes Förderband 13 (siehe Fig. 3), einen Bunker 14 am unteren Ende des Sternsiebs 11, einen Tragrahmen mit weiteren Bestandteilen und ein Raupenfahrwerk 15 auf. Ebenfalls vorhanden aber nicht zeichnerisch dargestellt sind Antriebs- und Hydraulikaggregate, Getriebe und dergleichen. Das Antriebsaggregat ist vorzugsweise unterhalb des Bunkers 14 angeordnet.A screening machine 10 has according to Fig. 1 an obliquely upward star screen 11, which may also be a pulley screen, a longitudinal belt conveyor 12, a lower, transverse conveyor belt 13 (see Fig. 3 ), a bunker 14 at the lower end of the star screen 11, a support frame with other components and a crawler 15 on. Also available but not shown in the drawing are drive and hydraulic units, transmission and the like. The drive unit is preferably arranged below the bunker 14.

Die Siebmaschine 10 weist unten am Tragrahmen zwei parallel zueinander längsgerichtete Tragschienen 16, 17 auf. Diese sind hinsichtlich ihrer Breite und Spurweite an die Ablaufrollen 18 eines LKWs mit Hakenliftvorrichtung 19 angepasst, siehe Fig. 2.The screening machine 10 has at the bottom of the support frame two parallel longitudinal guide rails 16, 17. These are adapted in terms of their width and track to the discharge rollers 18 of a truck with hook lift device 19, see Fig. 2 ,

Die Siebmaschine 10 weist an einer dem Bunker 14 zugeordneten Stirnseite eine Aufnahme für einen Lifthaken 20 auf. Die Aufnahme besteht hier aus einem umgekehrt U-förmigen Bügel 21, der mit einer Aufnahmeöse 22 für den Lifthaken 20 versehen ist. Dabei ist der Bügel 21 schwenkbar zwischen einer aufrechten (vertikalen) Transportposition und einer demgegenüber abwärts geklappten, horizontalen Arbeitsposition, siehe Fig. 3. Dort zeigt die Aufnahmeöse 22 nach unten und ist nicht sichtbar. Der Bügel 21 ist in beiden Positionen mechanisch arretierbar.The screening machine 10 has a receptacle for a lift hook 20 at a bunker 14 associated end face. The receptacle here consists of an inverted U-shaped bracket 21, which is provided with a receiving eye 22 for the lift hook 20. In this case, the bracket 21 is pivotable between an upright (vertical) transport position and a contrast folded down, horizontal working position, see Fig. 3 , There, the receiving lug 22 points downwards and is not visible. The bracket 21 is mechanically locked in both positions.

In der aufrechten Transportposition gemäß Fig. 1 liegt der Bügel 21 an einer Bunkerstirnseite 23 an. Der Bunker 14 befindet sich in Fig. 1 ebenfalls in einer Transportposition für den Transport auf dem LKW, sodass die Gesamtlänge aus Bunker 14 und unter demselben beginnenden Sternsieb 11 minimiert ist.In the upright transport position according to Fig. 1 the bracket 21 abuts against a bunker front side 23. The bunker 14 is located in Fig. 1 also in a transport position for transport on the truck, so that the total length of bunker 14 and under the same starting star screen 11 is minimized.

In der Arbeitsposition gemäß Fig. 3 liegt der Bunker 14 mit seinem stirnseitigen Ende auf dem Bügel 21 auf und ist relativ zum Sternsieb 11 aus seiner Transportposition herausgeschoben.In the working position according to Fig. 3 is the bunker 14 with its front end on the bracket 21 and is pushed relative to the star screen 11 from its transport position.

Zwischen einer Transportposition einerseits und Arbeitsposition andererseits hin- und herbewegbar sind auch der Bandförderer 12 und das Förderband 13, vergleiche Fig. 1 und 3. In Fig. 1 sind Bandförderer 12 und Förderband 13 zumindest teilweise abwärts geschwenkt bzw. eingeklappt.Between a transport position on the one hand and working position on the other hand reciprocally movable and the belt conveyor 12 and the conveyor belt 13, see Fig. 1 and 3 , In Fig. 1 Belt conveyor 12 and conveyor belt 13 are at least partially pivoted down or folded.

Das Raupenfahrwerk 15 ist bezogen auf die Längsrichtung der Siebmaschine 10 etwa mittig angeordnet und weist hier zwei zueinander parallele Raupen 24, 25 auf, welche außenseitig der Tragschienen 16, 17 höhenverstellbar gehalten sind. In einer Transportposition, siehe Fig. 2, liegen die Unterseiten der Raupen 24, 25 etwas tiefer als die Unterseiten der Tragschienen 16, 17. In der ausgefahrenen Arbeitsposition, siehe Fig. 3, liegen die Unterseiten der Tragschienen 16, 17 etwa auf halber Höhe der Raupen 24, 25 oder darüber. Zusätzlich können nicht gezeigte Tragstützen am Tragrahmen der Siebmaschine vorgesehen sein, sodass die Last nicht allein auf dem ausgefahrenen Raupenfahrwerk ruht. Bevorzugt ist aber ein Betrieb mit ausgefahrenem Raupenfahrwerk 15 ohne zusätzliche Stützen. Die Siebmaschine ist dann im laufenden Betrieb mit Hilfe des Raupenfahrwerks 15 verfahrbar. Dadurch ist es möglich, langgestreckte und relativ hohe Abwurfkegel zu bilden.The crawler undercarriage 15 is arranged approximately centrally with respect to the longitudinal direction of the screening machine 10 and here has two mutually parallel tracks 24, 25, which are outside of the support rails 16, 17 held vertically adjustable. In a transport position, see Fig. 2 , The undersides of the beads 24, 25 are slightly lower than the undersides of the support rails 16, 17. In the extended working position, see Fig. 3 , The undersides of the support rails 16, 17 are about halfway up the caterpillars 24, 25 or above. In addition, not shown support posts may be provided on the support frame of the screening machine, so that the load is not resting alone on the extended crawler track. But preferred is an operation with extended crawler track 15 without additional supports. The screening machine can then be moved during operation with the aid of the crawler track 15. This makes it possible to form elongated and relatively high discharge cone.

An einer dem Bunker 14 gegenüberliegenden Stirnseite der Siebmaschine weisen die Tragschienen 16, 17 jeweils außenseitig eine Absetzrolle 26 auf. Deren Unterseite liegt etwas tiefer als die Unterseite der Tragschienen 16, 17. Die Absetzrollen 26 setzen beim Abladen der Siebmaschine 10 vom LKW auf dem Boden auf, siehe Fig. 2 und kommen nach dem Abladen vorzugsweise nur vom Boden frei, wenn das Raupenfahrwerk 15 ausgefahren wird in seine Arbeitsposition gemäß Fig. 3. In der Transportposition des Raupenfahrwerks 15 liegt dessen Unterseite etwa auf derselben Höhe wie die Unterseite der Rollen 26, siehe ebenfalls Fig. 2.At a bunker 14 opposite end side of the screening machine, the support rails 16, 17 each outside a Absetzrolle 26 on. Their underside is slightly lower than the bottom of the support rails 16, 17. The Absetzrollen 26 put on unloading the screening machine 10 from the truck on the ground, see Fig. 2 and preferably come off after unloading only from the ground when the crawler undercarriage 15 is extended in its working position according to Fig. 3 , In the transport position of the crawler track 15 whose underside is approximately at the same height as the underside of the rollers 26, see also Fig. 2 ,

Die Verstellung des Raupenfahrwerks 15 erfolgt vorzugsweise hydraulisch durch geeignete Kolben-Zylinder-Einheiten. Möglich sind aber auch selbsthemmende Spindeltriebe in Verbindung mit Hydraulikmotoren oder andere Verstellantriebe. Die Vorwärts- oder Rückwärtsbewegung des Raupenfahrwerks 15 erfolgt insbesondere mit Hilfe von Hydraulikmotoren, Elektromotoren oder einen Verbrennungsmotor mit Getriebe. Entsprechende Antriebseinheiten können unter dem Bunker 14 angeordnet sein.The adjustment of the crawler track 15 is preferably carried out hydraulically by suitable piston-cylinder units. Also possible, however, are self-locking spindle drives in conjunction with hydraulic motors or other adjusting drives. The forward or backward movement of the crawler chassis 15 takes place in particular by means of hydraulic motors, electric motors or an internal combustion engine with gearbox. Corresponding drive units can be arranged under the bunker 14.
