SELECTIVE WOOD HARVESTING DEVICE

Traditional methods are currently used for first thinning, ie the clearing or chain saw is felled 5 and the wood is utilized to a small extent, ie the felled trees remain in place.

The thickness of the trunk of trees to be thinned is usually less than 20 cm. and uptake density of 5–10 acres. Normally, one pulpwood could be obtained from one thinning tree.

10 The collection of trees is mechanically hampered by the remaining trees, the scattered location of the trees to be collected and, for example, the damage caused to the tree roots by the tractor and trailer.

The device allows the felled wood to be transferred by a winch (4) to a feeder (1) with rotating rollers and pruning blades, both of which are known in the art. The feed device (1) is connected to a treatment combination (2) consisting of a winch, a measuring cut-off and transfer device and a chipper (3), which treatment combination is known per se.

It is pruned with the pruning blades in the feeder (1) and can then be cut to the desired length and fed the remainder, which is not suitable as a tuff or halo, to the chipper (3).

The choice of alternatives can be made by proximity or remote control or can be pre-programmed according to the diameter of the wood, all of which are known methods. The transfer of wood to the feeder (1) can also be done manually.

The method enabling the device is different from the known ones in that the felled wood can be transferred by means of a winch to the feeding device according to the invention, which enables an alternative treatment of the wood.

FIG. 1 shows a top view of a felling wood treatment combination (2) and a chipper (3) as well as according to the invention. . a lane feeder (1) placed on the agricultural tractor (5), either in front or behind.
