Description

Die Erfindung betrifft ein Bodenbearbeitungsgerät nach dem Oberbegriff von Anspruch 1.The invention relates to a harrow according to the preamble of claim 1.

Ein gattungsbildendes Bohrgerät geht beispielsweise aus der DE-A-195 14 288 hervor. Dieses Bohrgerät weist zum linearen Verschieben eines Bohrantriebes einen zweiseitig wirkenden Hydraulikzylinder auf. Ein derartiger Tandemzylinder weist ein durchgehendes Zylindergehäuse auf, zu dessen beiden Seiten jeweils ein Hubkolben ausfahrbar ist. Gegenüber einem einfach wirkenden Hubzylinder besitzt dieser Tandemzylinder den Vorteil einer besseren Knicksteifigkeit des auszufahrenden Hubkolbens aufgrund der geringeren Länge der beiden auszufahrenden Hubkolben.For example, a generic drill goes from the DE-A-195 14 288 out. This drill has for linear displacement of a drill drive on a two-sided hydraulic cylinder. Such a tandem cylinder has a continuous cylinder housing, to whose two sides in each case a reciprocating piston is extendable. Compared to a single-acting lifting cylinder of this tandem cylinder has the advantage of better buckling rigidity of auszufahrenden piston because of the shorter length of the two auszufahrenden reciprocating.

Wie bei einem einfach wirkenden Zylinder entspricht auch bei dem Tandemzylinder die maximale Hublänge etwa der Einbaulänge der Hubzylindereinrichtung. Der Hubweg ist hierdurch begrenzt.As with a single-acting cylinder, the maximum stroke length in the case of the tandem cylinder also corresponds approximately to the installation length of the lifting cylinder device. The stroke is limited by this.

Aus der JP-A-09078971 geht ein Bodenbearbeitungsgerät mit einer entgegengesetzt wirkenden Hubzylinderanordnung hervor. Hierbei sind zwei seitliche, einfach wirkende Hubzylinder versetzt und verschiebbar zu einem Tandemzylinder angeordnet.From the JP-A-09078971 goes out a harrow with an oppositely acting lifting cylinder arrangement. Here are two lateral, single-acting lifting cylinder offset and arranged displaceable to a tandem cylinder.

Auch bei dieser bekannten Hubzylinderanordnung ist die maximale Hublänge etwa auf die Einbaulänge des Tandemzylinders begrenzt.Also in this known lifting cylinder arrangement, the maximum stroke length is limited to about the installation length of the tandem cylinder.

Schließlich ist noch aus der DE-A-28 17 017 ein Horizontal-Pressbohrgerät bekannt, bei dem eine Bohrschnecke mittels zweier Haupthydraulikzylinder in den Boden eingepresst werden kann. Weiterhin sind zwei Nebenzylinder angeordnet, deren Hubkolben mit den Zylindergehäusen der Hauptzylinder verbunden sind, um so eine unabhängige Bewegung der Bohrschnecke gegenüber einem Bohrrohr zu erreichen. Auch bei dieser Anordnung ist die maximale Hublänge etwa auf die Einbaulänge der Hauptzylinder beschränkt.Finally, it is still out of the DE-A-28 17 017 a horizontal press drill known in which a drilling auger can be pressed by means of two main hydraulic cylinder in the ground. Furthermore, two slave cylinders are arranged, the reciprocating pistons are connected to the cylinder housings of the master cylinder, so as to achieve independent movement of the auger with respect to a drill pipe. Even with this arrangement, the maximum stroke length is limited to about the installation length of the master cylinder.

Die DE 1 922 486 beschreibt einen hydraulischen Teleskopausschub-Ausleger mit zwei gekoppelten Zylinderräumen und darin angeordneten Hubkolben. Die beiden Hubkolben sind in entgegengesetzter Richtung zueinander ausfahrbar.The DE 1 922 486 describes a hydraulic telescopic boom with two coupled cylinder chambers and arranged therein reciprocating. The two reciprocating pistons are extendable in the opposite direction to each other.

Aus der DE 2 353 106 ist eine Säulenbohrmaschine mit einer Tandemzylinderanordnung bekannt, mit welcher ein Bohrgerät gegenüber einer Basis verschoben werden kann.From the DE 2 353 106 a column boring machine with a tandem cylinder arrangement is known with which a drill can be moved relative to a base.

Der Erfindung liegt die Aufgabe zugrunde, ein Bodenbearbeitungsgerät anzugeben, welches bei einem einfachen und stabilen Aufbau eine möglichst große Verschiebebewegung mittels einer Hubzylinderanordnung erlaubt.The invention has for its object to provide a harrow, which allows the largest possible displacement movement by means of a Hubzylinderanordnung in a simple and stable structure.

Die Aufgabe wird erfindungsgemäß durch ein Bodenbearbeitungsgerät mit den Merkmalen des Anspruchs 1 gelöst. Bevorzugte Ausführungsformen sind in den abhängigen Ansprüchen angegeben.The object is achieved by a harrow with the features of claim 1. Preferred embodiments are given in the dependent claims.

Die erfindungsgemäße Vorrichtung ist dadurch gekennzeichnet, dass die beiden Hubzylindereinrichtungen jeweils mindestens einen Hubzylinder mit Zylindergehäuse aufweisen, welche nebeneinander angeordnet und miteinander fest verbunden sind. Hierdurch wird eine stabile und insgesamt kompakte Verstelleinrichtung erreicht. Gegenüber einem einfach wirkenden Hubzylinder kann mit der erfindungsgemäßen Anordnung bei gleicher Einbaulänge praktisch die doppelte Hublänge erreicht werden.The device according to the invention is characterized in that the two lifting cylinder devices each at least have a lifting cylinder with cylinder housing, which are arranged side by side and firmly connected to each other. As a result, a stable and overall compact adjustment is achieved. Compared to a single-acting lifting cylinder can be achieved with the inventive arrangement with the same installation length practically double the stroke length.

Eine bevorzugte Ausführungsform der Erfindung besteht darin, dass die Hubzylinder der beiden Hubzylindereinrichtungen gleich ausgebildet sind. Dies schafft die Möglichkeit der kostengünstigen Beschaffung von Gleichteilen. Insbesondere ist die Länge der einzelnen Zylindergehäuse oder der Hubzylinder im eingefahren und ausgefahrenen Zustand gleich. So kann eine optimale Ausnutzung der Baulänge im Verhältnis zum Hubweg erreicht werden. Bevorzugt sind zumindest alle Hubzylinder einer der Hubzylindereinrichtungen gleich.A preferred embodiment of the invention is that the lifting cylinder of the two Hubzylindereinrichtungen are the same. This creates the possibility of cost-effective procurement of identical parts. In particular, the length of the individual cylinder housing or the lifting cylinder in the retracted and extended state is the same. Thus, an optimal utilization of the overall length in relation to the stroke can be achieved. Preferably, at least all lifting cylinders of one of the lifting cylinder devices are the same.

Erfindungsgemäß weist die erste Hubzylindereinrichtung mindestens zwei Hubzylinder und die zweite Hubzylindereinrichtung einen Hubzylinder auf, der mittig zu den mindestens zwei Hubzylindern der ersten Hubzylindereinrichtung angeordnet ist. Die Hubzylinder können dabei beispielsweise auf einer Linie oder dreiecksförmig zueinander angeordnet sein. Durch einen einzigen mittigen Hubzylinder sowie zwei nebengeordneten Hubzylindern können Kippmomente aufgrund der versetzten Anordnung vermieden werden. Selbstverständlich kann die erste Hubzylindereinrichtung auch drei, vier oder mehr Zylinder aufweisen, welche ringförmig oder in sonstiger Weise gleichmäßig verteilt um die zentral angeordnete zweite Hubzylindereinrichtung angeordnet sind. Auch die zweite Hubzylindereinrichtung kann aus mehreren Hubzylindern, etwa aus einem Paket von zwei, drei, vier oder mehr Hubzylindern, bestehen, wobei dieses Paket dann mittig zur ersten Hubzylindereinrichtung angeordnet sein kann.According to the invention, the first lifting cylinder device has at least two lifting cylinders and the second lifting cylinder device has a lifting cylinder which is arranged centrally relative to the at least two lifting cylinders of the first lifting cylinder device. The lifting cylinder can be arranged, for example, on a line or triangular to each other. Tilting moments due to the staggered arrangement can be avoided by a single central lifting cylinder and two auxiliary lifting cylinders. Of course, the first lifting cylinder device may also have three, four or more cylinders, which are arranged in a ring-shaped or otherwise evenly distributed manner around the centrally arranged second lifting cylinder device. The second lifting cylinder device may consist of a plurality of lifting cylinders, such as a package of two, three, four or more lifting cylinders, this package may then be arranged centrally to the first Hubzylindereinrichtung.

Eine zweckmäßige Weiterbildung besteht nach der Erfindung darin, dass der mittige Hubzylinder der zweiten Hydraulikzylindereinrichtung unterschiedlich ausgebildet ist zu den umgebenden Hubzylindern der ersten Hydraulikzylindereinrichtung. Beispielsweise kann der mittige Hubzylinder mit einer stärkeren Hubkraft und mit einem knicksteiferen Hubkolben ausgebildet sein, so dass eine gleiche Kraftaufbringung und Steifigkeit wie durch die umgebenden Hydraulikzylinder erreicht wird.An expedient development according to the invention is that the central lifting cylinder of the second hydraulic cylinder device is designed differently to the surrounding lifting cylinders of the first hydraulic cylinder device. For example, the central lifting cylinder may be formed with a stronger lifting force and with a kink-stiffer lifting piston, so that a same force application and rigidity as achieved by the surrounding hydraulic cylinder.

Eine gute Montierbarkeit ergibt sich nach der Erfindung dadurch, dass ein Adapterglied vorgesehen ist, an dem einerseits die mindestens zwei Hubzylinder der ersten Hydraulikzylindereinrichtung und andererseits ein zentrales Anschlusselement angeordnet sind. Die Hubzylinderanordnung kann somit wie ein einzelner Hydraulikzylinder angeschlossen werden. Dies gewährt die Möglichkeit, in einfacher Weise bestehende Geräte umzurüsten, so dass für diese nahezu eine Verdoppelung des Verschiebeweges erreichbar ist.A good mountability results according to the invention in that an adapter member is provided on which on the one hand the at least two lifting cylinders of the first hydraulic cylinder device and on the other hand a central connecting element are arranged. The lifting cylinder arrangement can thus be connected like a single hydraulic cylinder. This allows the possibility to easily convert existing equipment, so that almost doubling of the displacement is achievable for this.

Weiter ist es nach der Erfindung besonders zweckmäßig, dass die Zylindergehäuse über mindestens ein starres Trägerelement miteinander fest verbunden sind. Die Zylindergehäuse können dabei durch entsprechende Befestigungseinrichtungen lösbar an einem plattenförmigen, starren Träger befestigt sein. Die einzelnen Hubzylinder können so in einfacher Weise ausgetauscht werden, so dass gewünschte Hublängen und Stellkräfte einstellbar sind. An dem Trägerelement kann auch eine gemeinsame Anschlusseinrichtung für die Hydraulikversorgung vorgesehen sein. Dies vereinfacht die Zuführung von Hydraulikleitungen und vermeidet Behinderungen und Kollisionen.Further, it is particularly expedient according to the invention for the cylinder housings to be firmly connected to one another via at least one rigid carrier element. The cylinder housing can be releasably secured by appropriate fasteners to a plate-shaped, rigid carrier. The individual lifting cylinders can be replaced in a simple manner, so that desired stroke lengths and actuating forces are adjustable. A common connection device for the hydraulic supply can also be provided on the carrier element. This simplifies the supply of hydraulic lines and avoids obstructions and collisions.

Eine Verbesserung der Stabilität und Knicksteifigkeit ergibt sich erfindungsgemäß dadurch, dass die Basis eine Linearführung aufweist, an welcher das mindestens eine Trägerelement anliegt und daran entlang geführt ist. Die zusätzliche Führung des Trägerelementes mit den Zylindergehäusen führt zu einer zusätzlichen Versteifung, was der Knickgefahr vorbeugt.An improvement of the stability and buckling resistance results according to the invention in that the base has a linear guide on which the at least one carrier element rests and is guided along it. The additional guidance of the carrier element with the cylinder housings leads to an additional stiffening, which prevents the danger of buckling.

Nach der Erfindung ist diese Ausführungsform dadurch weitergebildet, dass die Linearführung an einem aufstellbaren Mast angeordnet ist, und dass die Linearführung zum Führen des Trägerelementes und des Schlittens ausgebildet ist. Es muss somit keine separate Führungseinrichtung vorgesehen sein, sondern das Trägerelement wird an der vorhandenen Schlittenführung mitgeführt.According to the invention, this embodiment is further developed in that the linear guide is arranged on an erectable mast is, and that the linear guide is designed for guiding the carrier element and the carriage. It must therefore be provided no separate guide means, but the carrier element is carried along the existing slide guide.

Weiterhin ist es nach der Erfindung bevorzugt, dass zwei plattenförmige Verbindungsglieder vorgesehen sind, die an den Endbereichen der Zylindergehäuse befestigt sind. Dies führt ebenfalls zu einer Verbesserung der Steifigkeit. Die Verbindungsglieder können am Trägerelement angeordnet sein.Furthermore, it is preferred according to the invention that two plate-shaped connecting members are provided, which are fastened to the end regions of the cylinder housing. This also leads to an improvement in rigidity. The connecting links can be arranged on the carrier element.

Weiterhin ist es nach der Erfindung vorteilhaft, dass an dem Schlitten ein Bodenbearbeitungswerkzeug angeordnet ist. Dies kann insbesondere ein Bohrwerkzeug sowie der dazugehörige Bohrantrieb oder ein einzupressender Pfahl und das dazugehörige Halte- oder Spannelement sein. Zusätzlich oder alternativ kann am Schlitten ein Rüttler vorgesehen sein. Grundsätzlich können an dem Schlitten auch andere Werkzeuge, Antriebe oder sonstige Geräte angeordnet sein, welche linear zu verschieben sind. Die erfindungsgemäße Vorrichtung mit einer Hubanordnung kann grundsätzlich auch für verschiedenste Anwendungszwecke zum Einsatz kommen, wobei die Anwendung als Bodenbearbeitungsgerät für den Tiefbau oder zur Gewinnung von Bodenschätzen besonders bevorzugt ist. Das Bodenbearbeitungsgerät kann insbesondere ein Bohrgerät und/oder ein Rüttelgerät sein.Furthermore, it is advantageous according to the invention that a tilling tool is arranged on the carriage. This may in particular be a drilling tool and the associated drill drive or a pole to be pressed in and the associated holding or tensioning element. Additionally or alternatively, a vibrator may be provided on the carriage. In principle, other tools, drives or other devices can be arranged on the carriage, which are to be moved linearly. The device according to the invention with a lifting arrangement can in principle also be used for a very wide variety of purposes, the application being particularly preferred as a soil cultivation device for civil engineering or for the extraction of mineral resources. The soil cultivating device may in particular be a drilling device and / or a vibrating device.

Die Erfindung ermöglicht es, bei geringer Totlänge der Hubzylinderanordnung lange Vorschubwege zu erhalten. Im Hinblick auf die Kraftaufnahme ist es besonders vorteilhaft, dass die Hubzylinder der beiden Hubzylindereinrichtungen parallel zueinander verlaufen. Geeigneterweise verlaufen die Hubzylinder auch parallel zur Führungsrichtung der Linearführung und/oder zum Mast. Eine besonders hohe Knicksteifigkeit kann dadurch erhalten werden, dass die Hubzylinder rotationssymmetrisch zur Vorschubrichtung der Hubzylinderanordnung vorgesehen werden.The invention makes it possible to obtain long feed paths with a small dead length of the lifting cylinder arrangement. With regard to the power consumption, it is particularly advantageous for the lifting cylinders of the two lifting cylinder devices to run parallel to one another. Suitably, the lifting cylinders are also parallel to the guide direction of the linear guide and / or the mast. A particularly high buckling stiffness can thereby be obtained that the lifting cylinders are provided rotationally symmetrical to the feed direction of the lifting cylinder assembly.

Die Erfindung kann in einfacher Weise bei üblichen Bodenbearbeitungsvorrichtungen realisiert werden, indem die erfindungsgemäße Hubzylinderanordnung am Anlenkpunkt eines bekannten Vorschubzylinders angeordnet wird.The invention can be realized in a simple manner in conventional tillage devices by the lifting cylinder assembly according to the invention is arranged at the articulation point of a known feed cylinder.
