Device for turning a tree trunk

The invention relates to a device for turning a tree trunk during its processing, such as delimbing and / or debarking.

Tree trunks in the forest are usually delimbed or debarked. As soon as one side of the tree trunk has been processed, it is necessary to turn the tree trunk in order to edit the other side as well. This turning is especially important for logs of thicker strength classes very difficult and, if done by hand, very forceful.

From the German patent specification 24 52 481 is for example also a device for mechanical delimbing and / or debarking tree trunks known, wel-

before being pulled over the tree trunk with a tractor will. Here, too, after editing the one Side of the tree trunk it is necessary to turn the tree trunk. This is still done by hand today with the so-called turning hook.

The inventor has set himself the goal of a device of the above kind to develop, which a turning of the tree trunk in a simple manner without further

To solve this problem that leads to a support box Wheels running in the same direction of rotation are arranged, which take up the tree trunk between them .

According to the invention, these wheels can by hand by means of a Ratchet can be set in motion »However, a motor drive is preferred, which is in a further improved Embodiment of the invention from Tug is controlled from remotely.

So that the wheels can attack the tree trunk better, they should be provided with teeth on the circumference. Farther should be formed in the support box between the wheels, a recess for receiving the tree trunk. These The hollow cannot be completely filled by tree trunks of a stronger strength class, but theirs presses against it Weight considerably more on the teeth, so that turning is possible without difficulty. Tree trunks On the other hand, weaker strength classes lie deeper in the trough, so that attacking the teeth is again improved is.

The wheels should preferably be mounted on shafts which are rotated by a motor in the same direction of rotation.

are set. For this purpose, the invention provides that the shafts with intersecting V-belts with a drive shaft arranged approximately in the middle of the support box are connected and embrace them from both sides. If necessary, between the drive shaft and motor still transmission gears and further gear elements can be provided. As the device is its application According to the invention, the energy source for the motor is a battery intended. The motor itself is controlled via a remote control device, with the transmitter on the tugboat.

Of course, several wheels can also be arranged on one shaft.

The invention is also intended to provide a method for turning a tree trunk during its processing, such as delimbing and / or debarking, in which in a support box arranged wheels, which the tree trunk between take up, be moved remotely in the same direction of rotation.

Further advantages, features and details of the invention emerge from the following description one more preferred! Execution example as well as based on the i drawing; this shows in

Figure 1 is a plan view of a erfindungsgemaüe: _'t An apparatus for turning by tree trunks;

J
j A device for turning tree trunks has a

te support box 1, on which a box 2, in particular, 7 for receiving a drive and its control is formed fishing. In this case consists of the supporting box 1 from a ^fi end wall 3, a center panel 4 and an end wall 5. t end wall 3, central wall 4 and end wall 5 are provided with an I trough-shaped recess 6, as-I MACHINES SHOW is rather shown in FIG. 2 In this trough-shaped recess 6 tree trunks are inserted, which are to be debarked , for example, I '.

Front wall 3 and central wall 4 are also connected by a support wall 7. This support wall 7 divides two compartments 8 and 9, in which wheels 10 are rotatably mounted, the wheels 10 being provided with teeth 11 on the circumference. Four wheels 10 each are mounted on a shaft 12, which in turn rotates in two bearing shells 13 and 14. After Bearing shell 14, the shafts 12 are each attacked by V-belts 15 and 16, which, for example, from f drive chains can exist. Both V-belts encompass an approximately centrally arranged drive shaft 17, see above that by this arrangement the rotation of the wheels 10 is effected in the same direction of rotation. The rotation of the "j drive shaft 17 is taken over by a further belt 18, which

Belt 18, on the other hand, from drive shaft j 17 wraps around a gear shaft 19, which protrudes through end wall 5 f., Into a transmission gear 20 and M is connected to a motor 21 here.

run is carried out by a remote control device 23.

To delimb and debark a tree trunk by means of a device as it is, for example, in the German '"

After this process S can be remotely controlled from the tractor from the engine 21 in ^l; Movement is set and the wheels 10 are set in rotary motion via the corresponding arrangement of V-belts 15, 16, drive shaft 17, belt 18, gear shaft 19 and gear 20. This results in a turning; of the trunk, so that the not yet delimbed or debarked side of the tree trunk comes up and can now be processed with the device. j '
