Description

Die Erfindung betrifft eine Bodenbearbeitungsvorrichtung mit den Merkmalen des Oberbegriffs des Anspruchs 1. Eine solche Bodenbearbeitungsvorrichtung ist ausgebildet mit einem Trägergerät, einem Mast, der einen Mastverlauf bildet, und der ein Mastunterteil, welches am Trägergerät angelenkt ist, ein Mastoberteil und mindestens ein Mastverlängerungsstück aufweist, wobei das Mastverlängerungsstück zum Vergrößern der Mastlänge zwischen Mastunterteil und Mastoberteil in den Mastverlauf einfügbar ist, und wobei das Mastverlängerungsstück zum Verringern der Mastlänge vom Mastoberteil und vom Mastunterteil lösbar und aus dem Mastverlauf entfernbar ist, und das Mastoberteil bei entferntem Mastverlängerungsstück unmittelbar am Mastunterteil befestigbar ist, einem Arbeitsschlitten, welcher entlang des Mastes verschiebbar geführt ist, und mindestens einem Vorschubseil zum Verschieben des Arbeitsschlittens, welches zumindest bereichsweise längs des Mastes verläuft.The invention relates to a soil cultivating device having the features of the preamble of claim 1. Such a cultivating device is designed with a carrier device, a mast which forms a mast course, and a mast lower part, which is articulated on the carrier device, has a mast top part and at least one mast extension piece, wherein the mast extension piece for increasing the mast length between the mast base and mast top is inserted into the mast course, and wherein the mast extension piece for reducing the mast length of the mast top and the mast base detachable and removable from the mast, and the mast top with mast extension piece is directly attachable to the mast base, a working carriage, which is guided displaceably along the mast, and at least one feed cable for displacing the working carriage, which extends at least partially along the mast.

Es ist bekannt, beispielsweise aus EP 1 849 919 A1 , Bodenbearbeitungsgeräte mit mehrteiligen Masten vorzusehen, bei denen im Mastverlauf angeordnete Mastverlängerungsstücke zum Transport entfernt werden und die verbleibenden Mastteile anschließend wieder zusammengesetzt werden. Durch das Entfernen der Mastverlängerungsstücke aus dem Mastverlauf können die Mastabmessungen zum Transport verringert werden. Durch erneutes Einfügen der Mastverlängerungsstücke können zum Bohrbetrieb die ursprünglichen Mastabmessungen wieder hergestellt werden.It is known, for example EP 1 849 919 A1 To provide tillage implements with multi-part masts, where mast extensions arranged in the mast pattern are removed for transport and the remaining mast parts are then reassembled. By removing the mast extensions from the mast track, the mast dimensions for transport can be reduced. By re-inserting the mast extension pieces, the original mast dimensions can be restored for drilling.

Aufgabe der Erfindung ist es, eine gattungsgemäße Bodenbearbeitungsvorrichtung so weiterzubilden, dass bei besonders hoher Zuverlässigkeit ein besonders einfacher, schneller und sicherer Betrieb, insbesondere im Hinblick auf das Umrüsten zwischen einer Betriebskonfiguration und einer Transportkonfiguration der Bodenbearbeitungsvorrichtung, möglich ist.The object of the invention is to develop a generic tillage device so that, with particularly high reliability, a particularly simple, faster and safer operation, especially with regard to the conversion between an operating configuration and a transport configuration of the tillage device is possible.

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

Die erfindungsgemäße Bodenbearbeitungsvorrichtung ist dadurch gekennzeichnet, dass eine Haspel zum Aufnehmen von Schlappseil vorgesehen ist, welches am Vorschubseil entsteht, wenn das Mastverlängerungsstück aus dem Mastverlauf entfernt wird und das Mastoberteil unmittelbar am Mastunterteil befestigt wird.The tillage device according to the invention is characterized in that a reel is provided for receiving Schlappseil, which is formed on the feed rope when the mast extension piece is removed from the mast course and the mast shell is attached directly to the mast base.

Die Erfindung beruht auf der Erkenntnis, dass sich bei einer gattungsgemäßen Bodenbearbeitungsvorrichtung im Vorschubseil Schlappseil bilden kann, wenn das Mastverlängerungsstück zum Transport aus dem Mastverlauf entfernt wird und das Mastunterteil und das Mastoberteil unmittelbar zusammengefügt werden. Dabei kann die Länge des Schlappseils einem Vielfachen der Länge des Mastverlängerungsstücks entsprechen, wenn das Vorschubseil mehrfach längs des Mastes hin- und hergeführt ist. Da dieses Schlappseil unter Umständen den Transport der Bodenbearbeitungsvorrichtung behindern oder sogar gefährden kann, war es nach dem Stand der Technik unter Umständen erforderlich, das Vorschubseil zum Transport zu entfernen oder es vollständig auf der Vorschubseilwinde aufzunehmen, was mit einem entsprechenden Zeitaufwand einhergeht, und zwar sowohl bei der Vorbereitung des Transports als auch beim Wiederaufstellen des Mastes, wenn das entfernte Vorschubseil erneut aufgezogen werden muss.The invention is based on the finding that in a generic tillage device in the feed rope Schlappseil can form when the mast extension piece is removed for transport from the mast track and the mast base and the mast shell are joined together directly. In this case, the length of the Schlappseils correspond to a multiple of the length of the mast extension piece, when the feed rope is repeatedly reciprocated along the mast. Since this slack rope may hinder or even endanger the transport of the tillage device, it may be necessary in the prior art to remove the feed rope for transport or to take it completely on the feed cable winch, which comes with a corresponding amount of time, both during the preparation of the transport as well as during the refitting of the mast, when the removed feed rope has to be opened again.

Hier setzt die Erfindung an und sieht eine Haspel vor, die zur temporären Aufnahme des sich bildenden Schlappseils eingerichtet ist. Durch solch eine Haspel kann die Schlappseilbildung unterbunden werden, ohne dass es erforderlich ist, das Vorschubseil vom Mast zu entfernen. Das Vorschubseil kann damit auch beim Transport am Mast verbleiben, was den Aufwand beim Abbau oder Wiederaufbau der Bodenbearbeitungsvorrichtung deutlich verringern kann.This is where the invention comes in and provides a reel which is set up for temporarily receiving the forming slack rope. Through such a reel, the slack rope can be prevented, without it being necessary to remove the feed rope from the mast. The feed rope can thus remain on the mast during transport, which can significantly reduce the effort in dismantling or rebuilding the tillage device.

Die erfindungsgemäße Bodenbearbeitungsvorrichtung kann insbesondere als Bohrgerät ausgebildet sein. Das erfindungsgemäße Trägergerät kann zweckmäßigerweise ein Fahrwerk, beispielsweise ein Raupenkettenfahrwerk aufweisen. Das Mastunterteil und somit der Mast sind zweckmäßigerweise um eine horizontal verlaufende Achse schwenkbar am Trägergerät angelenkt, so dass das Mastunterteil und damit der Mast zwischen einer vertikalen Betriebsposition und einer horizontalen Rüst- und Transportposition verschwenkt werden können. Am Arbeitsschlitten kann insbesondere ein Dreh- und/oder Rüttelantrieb und/oder eine Führung für ein Bodenbearbeitungswerkzeug, beispielsweise ein Bohrgestänge, vorgesehen sein. Bei dem Vorschubseil kann es sich insbesondere um ein Oberseil handeln, welches um die Mastoberseite herum zu einer Winde geführt ist. Es können auch weitere Vorschubseile vorgesehen sein, beispielsweise ein Unterseil, welches um die Mastunterseite herumgeführt ist.The tillage device according to the invention can be designed in particular as a drilling device. The carrier device according to the invention may expediently have a running gear, for example a crawler track running gear. The mast lower part and thus the mast are suitably articulated pivotably about a horizontally extending axis on the carrier, so that the mast base and thus the mast between a vertical operating position and a horizontal setup and transport position can be pivoted. In particular, a rotating and / or vibrating drive and / or a guide for a soil working tool, for example a drill string, may be provided on the working carriage. The feed cable may in particular be a top cable, which is guided around the mast top side to a winch. It can also be provided further feed ropes, for example, a sub-cable, which is guided around the mast bottom.

Die erfindungsgemäße Haspel ist zweckmäßigerweise als Drehhaspel ausgebildet, das heißt sie weist einen drehbar gelagerten Aufnahmekörper für das Seil auf. Der Aufnahmekörper kann beispielsweise Aufnahmearme aufweisen, die sich radial von der Drehachse der Haspel nach außen erstrecken. Der Aufnahmekörper kann auch als Spule ausgebildet sein.The reel according to the invention is expediently designed as a rotary reel, that is, it has a rotatably mounted receiving body for the rope. The receiving body may for example comprise receiving arms which extend radially from the axis of rotation of the reel to the outside. The receiving body may also be formed as a coil.

Eine bevorzugte Ausführungsform der Erfindung besteht darin, dass die Haspel lösbar am Mast befestigt ist. Dies erlaubt es, die Haspel lediglich dann anzubringen, wenn auch mit Schlappseilbildung zu rechnen ist, also in der Regel beim Transport der Bodenbearbeitungsvorrichtung. Beim Bodenbearbeitungsbetrieb kann die Haspel hingegen entfernt werden, so dass dieser Betrieb durch die Haspel nicht beeinträchtigt werden kann.A preferred embodiment of the invention is that the reel is releasably secured to the mast. This makes it possible to attach the reel only when slack rope formation is to be expected, that is usually during transport of the tillage device. In the tillage operation, the reel, however, can be removed, so that this operation can not be affected by the reel.

Die Haspel kann beispielsweise hydraulisch oder mechanisch lösbar am Mast befestigt sein.The reel, for example, be hydraulically or mechanically releasably secured to the mast.

Insbesondere kann vorgesehen sein, dass die Haspel am Mastunterteil angeordnet ist. Da dieses Mastunterteil beim Entfernen des Mastverlängerungsstücks, also dann, wenn das Schlappseil anfällt, in der Regel stationär bleibt, kann durch eine solche Anordnung die Betriebszuverlässigkeit weiter erhöht werden.In particular, it can be provided that the reel is arranged on the mast base. Since this mast lower part usually remains stationary during removal of the mast extension piece, that is, when the slack rope is obtained, the operating reliability can be further increased by such an arrangement.

Weiter ist es vorteilhaft, dass die Haspel in einem dem Trägergerät abgewandten Endbereich des Mastunterteils am Mastunterteil angeordnet ist, wobei insbesondere vorgesehen sein kann, dass die Haspel in Längsrichtung des Mastes über das Mastunterteil übersteht. Hierdurch wird die Seilführung weiter vereinfacht. Der dem Trägergerät abgewandte Endbereich des Mastunterteils ist bei senkrechtem Mastverlauf in der Regel der obere Endbereich des Mastunterteils. Aufgrund des erfindungsgemäßen Überstandes der Haspel in Längsrichtung des Mastes über das Mastunterteil hinweg kann insbesondere vorgesehen sein, dass sich die am Mastunterteil angeordnete Haspel in Längsrichtung des Mastes betrachtet im Bereich des Mastoberteils befindet, wenn das Mastoberteil zum Transport unmittelbar am Mastunterteil befestigt ist.Further, it is advantageous that the reel is arranged in an end region of the mast lower part facing away from the carrier device on the mast lower part, it being possible in particular for the reel to project beyond the mast lower part in the longitudinal direction of the mast. As a result, the cable guide is further simplified. The carrier device opposite end portion of the mast lower part is at normal mast course usually the upper end of the mast base. Due to the supernatant according to the invention of the reel in the longitudinal direction of the mast over the mast lower part away, it can be provided in particular that the reel arranged on the mast lower part is in the area of the mast upper part viewed in the longitudinal direction of the mast when the mast upper part is fastened directly to the mast lower part for transport.

Darüber hinaus ist es zweckmäßig, dass die Haspel auf einer dem Arbeitsschlitten abgewandten Mastrückseite angeordnet ist. Wenn sich der Mast zum Transport in einer horizontalen Position befindet, liegt diese Mastrückseite oberhalb des Mastes. Die Haspel befindet sich somit beim Transport in einem Bereich, der im Hinblick auf die Transportabmessungen in der Regel wenig kritisch ist.In addition, it is expedient that the reel is arranged on a mast back facing away from the work carriage. When the mast is in a horizontal position for transport, this rear of the mast is above the mast. The reel is thus located during transport in an area that is usually less critical in terms of transport dimensions.

Ein besonders zuverlässiger Verschiebebetrieb des Arbeitsschlittens kann dadurch gewährleistet werden, dass ein Seilspannzylinder vorgesehen ist, an dem ein Ende des Vorschubseils lösbar befestigt ist. Dieser Seilspannzylinder erlaubt es, das Vorschubseil beim Betrieb gespannt zu halten, so dass eine besonders präzise Schlittenverschiebung möglich ist. Der Seilspannzylinder kann insbesondere als Hydraulikzylinder ausgebildet sein. Er ist zweckmäßigerweise einerseits mit dem Vorschubseil und andererseits mit dem Mast verbunden. Insbesondere kann der Seilspannzylinder am Mastverlängerungsstück vorgesehen sein. Wird dann das Mastverlängerungsstück zum Transport entfernt, so wird damit auch der Seilspannzylinder, der zum Transport in der Regel nicht notwendig ist, entfernt, so dass das Transportgewicht vorteilhafterweise reduziert ist. Insbesondere kann vorgesehen sein, dass das Ende des Vorschubseils mit einer Seilöse am Seilspannzylinder befestigt ist, was den zum Betrieb erforderlichen Aufwand weiter reduziert. Beispielsweise kann vorgesehen sein, dass das Ende des Vorschubseils am Kolben des Seilspannzylinders befestigt ist.A particularly reliable displacement operation of the work carriage can be ensured by providing a cable tensioning cylinder to which one end of the feed cable is detachably fastened. This rope tensioning cylinder makes it possible to keep the feed rope tensioned during operation, so that a particularly precise carriage displacement is possible. The cable clamping cylinder can be designed in particular as a hydraulic cylinder. He is expediently connected on the one hand with the feed rope and on the other hand with the mast. In particular, the rope tensioning cylinder may be provided on the mast extension piece. If the mast extension piece is then removed for transport, the rope tensioning cylinder, which is generally not necessary for transport, is thus removed, so that the transport weight is advantageously reduced. In particular, it can be provided that the end of the feed rope is fixed with a cable eye on the cable clamping cylinder, which further reduces the effort required for operation. For example, it can be provided that the end of the feed cable is attached to the piston of the cable clamping cylinder.

Weiterhin ist es zweckmäßig, dass die Haspel eine Befestigungseinrichtung zum lösbaren Befestigen des Vorschubseils aufweist. Demgemäß kann vorgesehen werden, dass sich die Haspel nur dann im Seilverlauf des Vorschubseils befindet, wenn auch mit Schlappseilbildung zu rechnen ist. Hierdurch wird die Betriebszuverlässigkeit weiter erhöht. Insbesondere ist bevorzugt, dass die Befestigungseinrichtung zum lösbaren Befestigen der Seilöse des Vorschubseils vorgesehen ist. In diesem kann zum Transport in besonders einfacher Weise die Seilöse vom Seilspannzylinder entfernt werden und mit der Haspel verbunden werden.Furthermore, it is expedient that the reel has a fastening device for releasably securing the feed rope. Accordingly, it can be provided that the reel is only in the rope course of the feed rope, although with slack rope is expected. As a result, the operational reliability is further increased. In particular, it is preferred that the fastening means for releasable Attaching the cable eye of the feed rope is provided. In this can be removed from the cable tensioning cylinder for transport in a particularly simple manner and connected to the reel.

Erfindungsgemäß ist es, dass der Mast zwischen einer vertikalen Betriebsposition und einer horizontalen Rüst- und Transportposition schwenkbar am Trägergerät angeordnet ist, was den Transport vereinfacht.According to the invention, the mast is pivotally mounted on a carrier device between a vertical operating position and a horizontal set-up and transport position, which simplifies transport.

Eine weitere bevorzugte Weiterbildung der Erfindung liegt darin, dass ein Haspelantrieb zum Betätigen der Haspel vorgesehen ist, was einen automatischen Betrieb erlauben kann. Grundsätzlich könnte das Vorschubseil aber auch händisch auf die Haspel aufgespult werden.A further preferred embodiment of the invention is that a reel drive is provided for operating the reel, which may allow automatic operation. Basically, the feed rope could also be wound by hand on the reel.

Überdies ist zweckmäßig, dass eine Haspelbremse zum Festlegen der Haspel vorgesehen ist. Hierdurch kann verhindert werden, dass sich das Vorschubseil beim Transport ungewollt von der Haspel abspult.Moreover, it is expedient that a reel brake is provided for securing the reel. This can prevent that the feed rope unintentionally unwinds from the reel during transport.

Vorzugsweise weist das Mastoberteil zumindest eine Umlenkrolle für das Vorschubseil auf, was die Seilführung vereinfachen kann. Es können am Mastoberteil auch mehrere Umlenkrollen für das Vorschubseil vorgesehen sein.Preferably, the mast upper part has at least one deflection roller for the feed rope, which can simplify the cable guide. It can be provided on the mast upper part and several pulleys for the feed rope.

Die Erfindung betrifft auch ein Verfahren zum Betrieb einer erfindungsgemäßen Bodenbearbeitungsvorrichtung, bei dem der Mast mit eingefügtem Mastverlängerungsstück aus einer vertikalen Betriebsposition in eine horizontale Rüst- und Transportposition geschwenkt wird, die Haspel am Mast befestigt wird, das Mastverlängerungsstück vom Mastunterteil und vom Mastoberteil gelöst und entfernt wird und das Mastoberteil unmittelbar am Mastunterteil befestigt wird, und zumindest ein Teil des Vorschubseils auf der Haspel aufgespult wird. Hierdurch können das beim Entfernen des Mastverlängerungsstücks gebildete Schlappseil aufgenommen und die im Zusammenhang mit der erfindungsgemäßen Bodenbearbeitungsvorrichtung erläuterten Vorteile realisiert werden.The invention also relates to a method for operating a tillage apparatus according to the invention, in which the mast with inserted mast extension piece is pivoted from a vertical operating position to a horizontal set-up and transport position, the reel is attached to the mast, the mast extension piece is detached from the mast base and the mast upper part and removed is and the mast top is attached directly to the mast base, and at least a portion of the feed rope is wound on the reel. As a result, the slack rope formed during removal of the mast extension piece can be accommodated and the advantages explained in connection with the ground-working device according to the invention realized.

Besonders zweckmäßig ist es, dass die Haspel am Mast befestigt wird, nachdem der Mast in die horizontale Rüst- und Transportposition geschwenkt wurde. Dies ermöglicht eine besonders einfache Montage der Haspel.It is particularly expedient that the reel is attached to the mast after the mast has been pivoted to the horizontal set-up and transport position. This allows a particularly simple installation of the reel.

Weiterhin ist es zweckmäßig, dass zum Aufspulen des Vorschubseils ein Ende des Vorschubseils von einem am Mast, insbesondere an einem Seilspannzylinder, vorgesehenen ersten Befestigungspunkt gelöst wird und sodann an einem an der Haspel vorgesehenen zweiten Befestigungspunkt befestigt wird. Dies kann durch entsprechendes Versetzen der erfindungsgemäßen Seilöse realisiert werden. Gemäß dieser Ausführungsform wird die Haspel nur zum Aufnehmen des Vorschubseils beim Transport mit dem Vorschubseil verbunden, und ist ansonsten aus dem Seilverlauf entfernt, was die Betriebszuverlässigkeit weiter erhöht.Furthermore, it is expedient that, for winding up the feed rope, one end of the feed rope is released from a first attachment point provided on the mast, in particular on a cable tensioning cylinder, and then fastened to a second attachment point provided on the reel. This can be realized by appropriate displacement of the cable eye according to the invention. According to this embodiment, the reel is connected only to receive the feed rope during transport with the feed rope, and is otherwise removed from the cable course, which further increases the operational reliability.

Weiter ist es besonders zweckmäßig, dass der Seilspannzylinder entspannt wird, bevor das Mastverlängerungsstück entfernt wird. Dies erlaubt eine besonders einfache Demontage des Mastverlängerungsstücks.Furthermore, it is particularly expedient that the rope tensioning cylinder is relaxed before the mast extension piece is removed. This allows a particularly simple disassembly of the mast extension piece.

Ein Ausführungsbeispiel einer erfindungsgemäßen Bodenbearbeitungsvorrichtung ist in den Figuren 1 bis 3 dargestellt. Die Bodenbearbeitungsvorrichtung weist ein Trägergerät 3 mit einem Oberwagen auf, der auf einem als Raupenkettenfahrwerk ausgebildeten Fahrwerk angeordnet ist. An diesem Trägergerät 3 ist über ein Gelenk 32 mit horizontal verlaufender Gelenkachse ein Mast 1 angelenkt. Über dieses Gelenk 32 ist der Mast 1 zwischen der in Fig. 1 dargestellten Betriebsposition und der in den Figuren 2 und 3 dargestellten Rüst- und Transportposition verschwenkbar. Zum aktiven Verschwenken des Mastes 1 ist ein Nackenzylinder 33 vorgesehen, der einerseits am Mast 1 und andererseits am Trägergerät 3 angelenkt ist.An embodiment of a tillage device according to the invention is in the FIGS. 1 to 3 shown. The soil cultivation device has a carrier device 3 with an uppercarriage, which is arranged on a chassis designed as a crawler track undercarriage. At this carrier device 3, a mast 1 is articulated via a joint 32 with horizontally extending hinge axis. About this joint 32 is the mast 1 between the in Fig. 1 shown operating position and in the Figures 2 and 3 shown setup and transport position swivel. To active Pivoting the mast 1, a neck cylinder 33 is provided, which is hinged on the one hand to the mast 1 and on the other hand on the carrier device 3.

Am Mast 1 ist ein Arbeitsschlitten 6 vorgesehen, der in der Längsrichtung L des Mastes 1 verschiebbar am Mast 1 angeordnet ist. An diesem Arbeitsschlitten 6 kann beispielsweise ein Drehbohrantrieb 61 für ein Bohrgestänge vorgesehen sein.On the mast 1, a working carriage 6 is provided, which is arranged in the longitudinal direction L of the mast 1 slidably on the mast 1. At this work carriage 6, for example, a rotary drill 61 may be provided for a drill pipe.

Zum Verschieben des Arbeitsschlittens 6 ist unter anderem ein als Oberseil ausgebildetes Vorschubseil 8 vorgesehen, welches durch eine Seilwinde 25 betätigbar ist. Zum Spannen des Vorschubseils 8 ist an der Mastrückseite 18 des Mastes 1, das heißt auf der dem Arbeitsschlitten 6 abgewandten Mastseite, ein Seilspannzylinder 30 angeordnet. Der hydraulische Seilspannzylinder 30 ist einerseits, insbesondere an seinem Zylindergehäuse, mit dem Mast 1 verbunden, und andererseits, insbesondere an seiner Kolbenstange, mit dem Vorschubseil 8. Das Vorschubseil 8 weist dabei endseitig eine Seilöse 9 auf, über welche die Verbindung mit dem Seilspannzylinder 30 realisiert ist. Der Seilspannzylinder 30 dient in der in Fig. 1 dargestellten Arbeitsposition dazu, das Vorschubseil 8 gespannt zu halten. Vom Seilspannzylinder 30 läuft das Vorschubseil 8 über eine in einem oberen Bereich des Mastes 1 angebrachte Umlenkrolle 21 zum Arbeitsschlitten 6, an welchem zumindest eine weitere Umlenkrolle 26 vorgesehen ist. Über diese Umlenkrolle 26 des Arbeitsschlittens 6 läuft das Vorschubseil 8 wieder zum oberen Endbereich des Mastes 1 und von dort über eine zweite, hier nicht dargestellte Umlenkrolle nach unten zu der mit dem Mast 1 verbundenen Seilwinde 25, an welcher das zweite Ende des Vorschubseils 8 befestigt sein kann.To move the working slide 6, a feed rope 8 designed as a top rope is provided, among other things, which can be actuated by a cable winch 25. For tensioning the feed rope 8, a cable tensioning cylinder 30 is arranged on the rear mast side 18 of the mast 1, that is, on the mast side facing away from the working carriage 6. The hydraulic cable clamping cylinder 30 is on the one hand, in particular on its cylinder housing, connected to the mast 1, and on the other hand, in particular on its piston rod, with the feed rope 8. The feed cable 8 has at its end a cable eye 9, via which the connection with the cable clamping cylinder 30th is realized. The rope tensioning cylinder 30 serves in the in Fig. 1 shown working position to keep the feed rope 8 stretched. From the cable tensioning cylinder 30, the feed cable 8 runs over a mounted in an upper region of the mast 1 deflection roller 21 to the working slide 6, on which at least one further deflection roller 26 is provided. About this pulley 26 of the work carriage 6, the feed rope 8 runs again to the upper end of the mast 1 and from there via a second, not shown pulley down to the connected to the mast 1 winch 25 to which the second end of the feed rope 8 attached can be.

Wie insbesondere in Fig. 2 gezeigt ist, ist der Mast 1 dreiteilig ausgebildet und weist ein Mastunterteil 13 auf, an dem der Mast 1 über das Gelenk 32 mit dem Trägergerät 3 verbunden ist, ein Mastverlängerungsstück 12, welches sich bedarfsweise an das Mastunterteil 13 anschließt, und schließlich ein Mastoberteil 11, an dem die Umlenkrolle 21 angeordnet ist. In Fig. 1 ist exemplarisch ein weiteres Mastverlängerungsstück 12' zwischen Mastoberteil 11 und Mastunterteil 13 gezeigt.As in particular in Fig. 2 is shown, the mast 1 is formed in three parts and has a mast lower part 13, on which the mast 1 is connected via the joint 32 with the carrier device 3, a mast extension piece 12, which, if necessary, adjoins the mast lower part 13, and finally a mast upper part 11th on which the deflection roller 21 is arranged. In Fig. 1 By way of example, another mast extension piece 12 'is shown between the mast upper part 11 and the mast lower part 13.

Wie Figuren 2 und 3 zeigen, kann am Mast 1 bedarfsweise eine Haspel 2 vorgesehen werden, welche dazu dient, beim Umrüsten des Mastes 1 auftretendes Schlappseil am Vorschubseil 8 aufzunehmen. Insbesondere kann die Haspel 2 an der Mastrückseite 18 am Mastunterteil 13 angeordnet sein, und zwar in einem dem Trägergerät 3 abgewandten Endbereich 16 des Mastunterteils 13. Die Haspel 2 ist dabei im dargestellten Ausführungsbeispiel so angeordnet, dass sie über das Mastunterteil 13 übersteht und somit im Bereich des benachbarten Mastverlängerungsstücks 12 beziehungsweise Mastoberteils 11 angeordnet ist.As Figures 2 and 3 show, if required, a reel 2 can be provided on the mast 1, which serves to accommodate 1 occurring slack rope on the feed rope 8 when retrofitting the mast. In particular, the reel 2 can be arranged on the back of the mast 18 on the mast lower part 13, in a carrier device The reel 2 is in the illustrated embodiment arranged so that it protrudes beyond the mast base 13 and thus in the region of the adjacent mast extension piece 12 and mast shell 11 is arranged.

Die Figuren 1 bis 3 illustrieren verschiedene Verfahrensschritte beim Umrüsten der Bodenbearbeitungsvorrichtung von einer Betriebsposition in eine Transportposition in einem erfindungsgemäßen Verfahren. Zunächst wird der Mast 1, der in Fig. 1 in seiner vertikalen Betriebsposition gezeigt ist, beispielsweise durch Ausfahren des Nackenzylinders 33 in seine in Fig. 2 dargestellte Rüst- und Transportposition umgelegt. Sodann wird die Haspel 2 am Mastunterteil 13 angebaut, beispielsweise mechanisch und/oder hydraulisch. Der Seilspannzylinder 30 wird entspannt und das Mastverlängerungsstück 12 wird vom Mastoberteil 11 und 13 gelöst und mitsamt dem Seilspannzylinder 30 entfernt. Sodann wird das Mastoberteil 11 unmittelbar am Mastunterteil 13 befestigt. Dieser Zustand, bei dem der Mast 1 um die Länge des Mastverlängerungsstücks 12 verkürzt ist, ist in Fig. 3 dargestellt.The FIGS. 1 to 3 illustrate various steps in the conversion of the tillage device from an operating position to a transport position in a method according to the invention. First, the mast 1, the in Fig. 1 is shown in its vertical operating position, for example by extending the neck cylinder 33 in his in Fig. 2 displayed set-up and transport position. Then the reel 2 is attached to the mast base 13, for example mechanically and / or hydraulically. The rope tensioning cylinder 30 is relaxed and the mast extension piece 12 is released from the mast upper part 11 and 13 and removed together with the cable clamping cylinder 30. Then the mast upper part 11 is attached directly to the mast lower part 13. This state, in which the mast 1 is shortened by the length of the mast extension piece 12, is in Fig. 3 shown.

Beim Entfernen des Mastverlängerungsstücks 12 und dem unmittelbaren Zusammenfügen von Mastoberteil 11 und Mastunterteil 13 wird im Vorschubseil 8 eine Seillänge frei, die einem Vielfachen der Länge des Mastverlängerungsstücks 12 entspricht. Um in diesem Zusammenhang eine Schlappseilbildung zu vermeiden, kann das Vorschubseil 8 mittels der Haspel 2 aufgespult werden. Hierzu wird das Vorschubseil 8 über die Seilöse 9 an der Haspel 2 befestigt und die Haspel betätigt.When removing the mast extension piece 12 and the direct assembly of the mast upper part 11 and mast lower part 13, a rope length is released in the feed rope 8, which corresponds to a multiple of the length of the mast extension piece 12. In order to avoid a Schlappseilbildung in this context, the feed cable 8 can be wound by means of the reel 2. For this purpose, the feed rope 8 is attached via the cable eye 9 on the reel 2 and the reel operated.
