In den Figuren ist ein bevorzugtes Ausführungsbeispiel der erfindungsgemäßen Vorrichtung dargestellt.In the figures, a preferred embodiment of the device according to the invention is shown.

Die auf einem Gestell eines (nicht näher dargestellten) Nutzfahrzeuges angebrachte Vorrichtung zum Längsspalten von Langholz 9 umfasst eine im wesentlichen schalen- oder bogenförmig ausgebildete Ablage 6 zur im wesentlichen horizontal liegenden Aufnahme des Langholzstammes 9, und hat einen hydraulisch oder motorisch in Spaltrichtung gemäß Pfeil 10 angetriebenen Spaltkeil 4. Die Ablage 6 ist über ein Gelenk 8 und ein am Fahrzeugrahmen verschweisstes Blechteil 1 am Nutzfahrzeug dergestalt schwenkbar gelagert, dass es in Arbeitsstellung gemäß Figuren 1 und 2 nach Aussen vom Fahrzeuggestell weggeschwenkt, und in Ruhestellung zum Fahrzeugrahmen hingeschwenkt werden kann, wie dies in Figur 3 strichliert angedeutet ist.The mounted on a frame of a (not shown) commercial vehicle device for longitudinal splitting of long wood 9 comprises a substantially cup-shaped or arcuate tray 6 to substantially horizontally receiving the lumber trunk 9, and has a hydraulic or motor driven in the direction of the gap according to arrow 10 splitting wedge 4. The tray 6 is pivotally mounted on a hinge 8 and a welded to the vehicle frame sheet metal part 1 on the commercial vehicle such that it is in working position Figures 1 and 2 swung to the outside of the vehicle frame, and can be pivoted in the rest position to the vehicle frame, as in FIG. 3 is indicated by dashed lines.

Die Ablage 6 besitzt auf ihrer dem Spaltkeil 4 abgewandten Seite einen Anschlag 7, wobei der Anschlag insbesondere eine mit dem Spaltkeil 4 zusammenwirkende Messerschneide 11 trägt.The tray 6 has on its side facing away from the riving knife 4 a stop 7, wherein the stop in particular carries a cooperating with the riving knife 4 knife edge 11.

Der Antrieb für den Spaltkeil 4 weist einen auf dem Fahrzeuggestell liegend angeordneten bzw. abgestützten Hydraulikzylinder 3 auf. Der Hydraulikzylinder 3 des Spaltkeilantriebes gleitet in einem als Profilrohr ausgebildeten Zylinderlager 2, wobei die Wandung des Zylinderlagers 2 mit einem Gleitwerkstoff 5 ausgebildet bzw. versehen ist.The drive for the splitting wedge 4 has a hydraulic cylinder 3 arranged or supported on the vehicle frame. The hydraulic cylinder 3 of the riving knife drive slides in a cylindrical bearing 2 in the form of a profiled tube, wherein the wall of the cylindrical bearing 2 is formed or provided with a sliding material 5.

Die gesamte Vorrichtung ist in dem rückseitigen Bereich eines Nutzfahrzeuges angebracht, wobei das Nutzfahrzeug des weiteren einen Kran zur Aufnahme des Langholzstammes und zur Ablage auf die Halterung besitzt.The entire apparatus is mounted in the rear area of a utility vehicle, the utility vehicle further having a crane for receiving the logwood trunk and depositing it on the support.

Der Radius der im wesentlichen schalen- oder bogenförmig ausgebildeten Ablage bzw. Halterung entspricht einem durchschnittlichen Stammholzradius.The radius of the substantially cup-shaped or arc-shaped tray or holder corresponds to an average Stammholzradius.

Beim Spaltvorgang wird das zu spaltende Langholz 9 in die Auflage 6 gelegt, daraufhin fährt der Zylinder 3 mit dem Spaltkeil 4 aus und drückt das zu spaltende Holz 9 gegen die Gegenschneide 7, bis es durch die ansteigende Form des Spaltkeils auseinandergedrückt und in Längsrichtung (längs der Faser) gespalten wird.During the splitting process, the long wood to be split 9 is placed in the support 6, then the cylinder 3 moves out with the splitting wedge 4 and presses the wood to be split 9 against the counter-blade 7 until it is pushed apart by the rising shape of the splitting wedge and longitudinally (longitudinal the fiber) is split.

Der Antrieb erfolgt durch mindestens einen oben liegenden hydraulischen Kraftzylinder. Dieser ist in einem Profilrohr 2 geführt, damit der Spaltkeil 4 sich nicht verdrehen kann. Die Form der Ablage 6 bzw. des Gegenhalters gleicht annähernd einer Ellipse bzw. einem Halbkreis. In diesen wird das zu spaltende Material quer zur Faser eingelegt. Außerdem ist der Gegenhalter 6 abnehmbar bzw. drehbar gelagert, um für z. B. für den Transport Platz zu sparen.The drive is made by at least one overhead hydraulic power cylinder. This is guided in a profile tube 2, so that the riving knife 4 can not rotate. The shape of the tray 6 and the counter-holder is approximately equal to an ellipse or a semicircle. In these, the material to be split is inserted transversely to the fiber. In addition, the counter-holder 6 is removable or rotatably mounted to z. B. to save space for transport.

In einer besonderen Ausführungsform kann der oder die Hydraulikzylinder mit einem Bypassventil (Fig. 4) versehen sein, das das Öffnen des Spalters beschleunigt. Je nach Größe und Konstruktion des Spalters erfolgt das Öffnen und Schließen durch einen entsprechend groß dimensionierten Hydraulikzylinder und die dementsprechend notwendige Ölmenge relativ langsam. Da beim Öffnen der Spaltvorrichtung die erforderliche Kraft geringer ist als beim Spaltvorgang, kann der Rückstau im Zylinder durch das Bypassventil reduziert werden. Damit sinkt die notwendige Kraft und die Geschwindigkeit des Öffnungsvorgangs steigt. Beim Spaltvorgang ist das Bypassventil ohne Wirkung.In a particular embodiment, the hydraulic cylinder (s) may be provided with a bypass valve ( Fig. 4 ), which speeds up the opening of the splitter. Depending on the size and construction of the splitter, the opening and closing by a correspondingly large-sized hydraulic cylinder and the correspondingly necessary amount of oil is relatively slow. Since the force required when opening the cleavage device is less than during the cleavage process, the backflow in the cylinder can be reduced by the bypass valve. Thus, the necessary force decreases and the speed of the opening process increases. During the splitting process, the bypass valve has no effect.

Funktion Spalter schließt:Function splitter closes:

Bei geringem Spaltwiderstand ist Ventil 18 geöffnet, Ventil 17 und 18a geschlossen. Das rückströmende Medium wird über das Ventil addiert und fließt auf die Seite der größeren Zylinderfläche. Dadurch schließ der Spalter schneller. Stößt die Schneide dann auf das zu spaltende Material, so entsteht ein größerer Widerstand, öffnet somit Ventil 17, Ventil 18 ist geschlossen und das Medium der kleineren Zylinderfläche strömt dann direkt in den Tank zurück.With low gap resistance valve 18 is open, valve 17 and 18 a closed. The backflowing medium is added via the valve and flows to the side of the larger cylindrical surface. This closes the splitter faster. If the cutting edge then hits the material to be split, a greater resistance is created, thus opening valve 17, valve 18 is closed and the medium of the smaller cylindrical surface then flows directly back into the tank.

Funktion Zange öffnet:Function Forceps opens:

Das Medium fließt durch Ventil 18a, Ventil 17 geschlossen, Ventil 18 ist durch einen Vordruck von Leitung A gesperrt. Das Bypassventil ist somit ohne Wirkung.The medium flows through valve 18a, valve 17 closed, valve 18 is blocked by a form of line A. The bypass valve is thus without effect.

Der wesentliche Vorteil dieser Ausführung besteht in einem schnellen Schließen des Zylinders durch die regenerative Ölrückführung.The main advantage of this design is a quick closing of the cylinder by the regenerative oil return.

Bei einer weiteren, in den Figuren nicht näher dargestellten Ausführung der Erfindung kann vorgesehen sein, dass die Aufnahme zur Abstützung des Holzstammes in der Höhe verstellbar ist, und insbesondere hydraulisch oder mechanisch in der Höhe verschiebbar gelagert ist. Auf diese Weise gelingt es, dass der radial in den Holzstamm einzudringende Spaltkeil möglichst zum Stammholzzentrum hin ausgerichtet werden kann.In another, not shown in the figures embodiment of the invention can be provided that the receptacle for supporting the log is height adjustable, and in particular hydraulically or mechanically mounted in height displaceable. In this way it is possible that the riving knife to be penetrated radially into the log can be aligned as far as possible towards the log center.

Bei einer weiteren, in den Figuren ebenfalls nicht näher dargestellten Ausführung der Erfindung kann vorgesehen sein, dass die Aufnahme zur Abstützung des Holzstammes ein Auswurforgan aufweist, vermittels welchem der Holzstamm nach erfolgter Spaltung aus der Aufnahme ausgeworfen wird. Ein solches Auswurforgan kann beispielsweise ein in bzw. an der Aufnahme schwenkbar gelagertes Auswurfblech, oder ein in der Höhe veränderliches Hubelement sein. Das Auswurforgan ist von Vorteil wiederum durch einen Hydraulikzylinder angetrieben, welcher Hydraulikzylinder ebenfalls wiederum von Vorteil in waagerechter Lage, d.h. liegend angeordnet ist.In a further, not shown in the figures embodiment of the invention can be provided that the receptacle for supporting the log has a Auswurforgan, by means of which the log is ejected after splitting from the recording. Such an ejector can be, for example, a discharge plate pivotally mounted in or on the receptacle, or a variable height lifting element. The ejection member is in turn advantageously powered by a hydraulic cylinder, which hydraulic cylinder also in turn of advantage in a horizontal position, i. is arranged horizontally.
