Der Holzspalter ist dabei aus einem umgekehrt U-förmigen Gestell aus einer horizontalen Basis und zwei Schenkeln gebildet, wobei der eine Schenkel eine horizontal arbeitende Kolben-Zylinder-Einheit trägt, deren Kolben mit einem auf der Basis verschiebbaren, Spaltkeile tragenden Spaltkeilträger verbunden ist, und der andere Schenkel durch eine Druckplatte gebildet ist, und bei der die Greifvorrichtung an der Basis befestigt ist.Furthermore, a brochure with the company Schlang & Reichart entitled "Crane splitter" (S + R crane splitter KS 40) is a crane attached to a fixed crane Known wood splitter, which has a splitting device and a gripping device and grips, transports and splits the wooden part to be split in one operation. The log splitter is made of an inverted U-shaped frame from one horizontal base and two legs, one leg one horizontally working piston-cylinder unit carries, whose piston with one on the Base slidable, riving knife-bearing riving knife carrier is connected, and the other leg is formed by a pressure plate, and in which the gripping device is attached to the base.

Durch die DE-C2-199 10 429 ist ein Holzgreifer mit angebauter Kettensäge bekannt, die gegenüber dem Holzgreifer in Längsrichtung des zu sägenden Holzes verschiebbar ist.From DE-C2-199 10 429 a wood grab with a chain saw attached is known, compared to the wood grab in the longitudinal direction of the wood to be sawn is movable.

Ferner ist durch die WO-A1-03031129 eine dem Oberbegriff des Anspruchs 1 ähnliche Holzbearbeitungsvorrichtung bekannt, die jedoch nicht an einem Bagger, sondern an einem Hebekran angebracht ist. Diese bekannte Holzbearbeitungsvorrichtung weist bereits eine Sägevorrichtung für das zu bearbeitende Holzteil auf. Spaltvorrichtung und Sägevorrichtung können hydraulisch betrieben sein. Die Sägevorrichtung kann auch als Kettensäge ausgebildet und im Ruhezustand in der Basis eines U-förmigen Gestells aufgenommen sein. Schließlich kann zur Verschiebung einer den Spaltkeilen gegenüberliegenden Druckplatte eine Kolben-Zylinder-Einheit vorgesehen sein.Furthermore, WO-A1-03031129 is a preamble of claim 1 Similar woodworking device known, but not on an excavator, but is attached to a lifting crane. This known woodworking device already has a sawing device for the wooden part to be processed. Splitting device and sawing device can be operated hydraulically.

Mit der Sägevorrichtung kann nun das zu spaltende Holzteil von Langholz abgelängt werden, ehe es gespalten wird. Auch während dieses Ablängvorgangs ist die Bedienungsperson geschützt. Gesonderte Ablängvorgänge mit dazu nötigen Ablängwerkzeugen oder -maschinen können daher vermieden werden. Am Holzspalter ist ferner eine Zwickvorrichtung zum Zerteilen von zu spaltenden Holzteilen in deren Längsrichtung in zwei Hälften angebracht. Dadurch können beispielsweise auch dickere Baumstämme abgesägt und in Längsrichtung geteilt werden, so dass anschließend die Stammhälften nacheinander gespalten werden können.With the sawing device, the wooden part to be split can now be cut to length from long timber before it is split. The operator is also during this cutting process protected. Separate cutting operations with the necessary cutting tools machines can therefore be avoided. At the log splitter is also a lasting device for dividing wooden parts to be split in the longitudinal direction attached in half. This means that even thicker ones can be used Tree trunks are sawn off and divided lengthways so that afterwards the stem halves can be split one after the other.

In Fig. 1 ist ein Holzspalter 1 dargestellt, der an einem mit einem hydraulischen Versorgungssystem versehenen, nicht dargestellten Bagger über einen Rotator 2 zum Drehen des Holzspalters 1 angebaut ist. Der Holzspalter 1 ist aus einem umgekehrt U-förmigen Gestell 3 aus einer horizontalen Basis 4 und zwei Schenkeln 5, 6 gebildet, wobei der Schenkel 5 eine horizontal arbeitende Kolben-Zylinder-Einheit 7 trägt, deren Kolben 8 mit einem auf der Basis 4 verschiebbaren, Spaltkeile 9 tragenden Spaltkeilträger 10 verbunden ist. Die Einheit 7 ist in nicht dargestellter Weise mit dem hydraulischen Versorgungssystem des Baggers verbunden. Der andere Schenkel 6 ist durch eine Druckplatte 11 gebildet. Die Basis 4 besteht dabei aus zwei im Abstand zueinander und übereinander liegenden, miteinander verbundenen Hohlträgern 12, 13, deren Querschnitt aus den Figuren 2 - 5 hervorgeht. Der untere Hohlträger 13 weist zwei Schienen 14, 15 (s. auch Fig. 4) auf, auf denen der Spaltkeilträger 10 in Horizontalrichtung verfahrbar ist. Unterhalb des Rotators 2 ist eine Greifvorrichtung 16 am unteren Hohlträger 13 angebracht, die näher in Fig. 3 dargestellt ist. In der Nähe der Druckplatte 11 ist ferner am unteren Hohlträger 13 eine Sägevorrichtung in Form einer Kettensäge 17 befestigt, die näher in Fig. 2 dargestellt ist.In Fig. 1, a log splitter 1 is shown, the one with a hydraulic Supply system provided excavator, not shown, via a rotator 2 is mounted to turn the log splitter 1. The log splitter 1 is made of one reversed U-shaped frame 3 from a horizontal base 4 and two legs 5, 6 formed, wherein the leg 5 is a horizontally operating piston-cylinder unit 7 carries, the piston 8 with a slidable on the base 4, riving knife 9 supporting riving knife carrier 10 is connected. The unit 7 is not shown in FIG Way connected to the hydraulic supply system of the excavator. The other leg 6 is formed by a pressure plate 11. The base 4 exists of two, at a distance from each other and one above the other connected hollow beams 12, 13, the cross section of which is shown in FIGS. 2-5 evident. The lower hollow beam 13 has two rails 14, 15 (see also FIG. 4), on which the riving knife carrier 10 can be moved in the horizontal direction. Below the Rotator 2, a gripping device 16 is attached to the lower hollow support 13, the is shown in more detail in Fig. 3. In the vicinity of the pressure plate 11 is also at the bottom Hollow beam 13 attached a sawing device in the form of a chainsaw 17, the closer is shown in Fig. 2.

Die Druckplatte 11 ist am rechten Ende des Gestells 3 vertikal verschiebbar angeordnet. Zur Verschiebung der Druckplatte 11 ist eine weitere Kolben-Zylinder-Einheit 18 vorgesehen, die in nicht dargestellter Weise an das hydraulische Versorgungssystem des Baggers angeschlossen ist.The pressure plate 11 is vertically displaceable at the right end of the frame 3 arranged. Another piston-cylinder unit is used to move the pressure plate 11 18 provided to the hydraulic in a manner not shown Supply system of the excavator is connected.

Die Arbeitsweise der Holzbearbeitungsvorrichtung ist folgende: Der Bagger fährt mit dem Holzspalter 1, dessen Druckplatte 11 nach oben hochgezogen ist, zu einem Holzlagerplatz und greift mit der Greifeinrichtung 16 ein Langholzteil auf. Dann wird mit der Kettensäge 17 ein etwa 1 m langes Holzteil abgesägt, wonach die Druckplatte 11 wieder nach unten verfahren wird, so dass nun das Holzteil zwischen der zurückgefahrenen Keilträgerplatte 10 und der Druckplatte 11 angeordnet ist. Dann wird die Einheit 7 betätigt, und das Holzteil wird mittels der Keile 9, deren Anzahl hier sechs beträgt (es sind jedoch bis zu 10 Keile möglich), gespalten.The working method of the woodworking device is as follows: The excavator travels the log splitter 1, the pressure plate 11 of which is pulled upwards, into one Wood storage place and picks up a long wood part with the gripping device 16. Then it will be sawn off with the chainsaw 17 an approximately 1 m long wooden part, after which the Pressure plate 11 is moved back down, so that now the wooden part between the retracted wedge support plate 10 and the pressure plate 11 is arranged. Then the unit 7 is actuated, and the wooden part is by means of the wedges 9, the Number here is six (however, up to 10 wedges are possible), split.

Die Greifvorrichtung 16 wird bei Betätigung der Einheit 7 etwas zeitverzögert vollautomatisch geöffnet, damit keine Beschädigung der Greifeinrichtung 16 durch die vorfahrenden Spaltkeile 9 auftreten kann.The gripping device 16 is somewhat delayed when the unit 7 is actuated opened fully automatically, so that no damage to the gripping device 16 by the leading riving knife 9 can occur.

Die Zwickvorrichtung 29 muss vollständig geöffnet sein, damit der Spaltprozess starten kann. The lasting device 29 must be fully open for the splitting process can start.
