Embodiment Construction

[0053] attached figure 1 The device 10 is shown in the rest position. The device 10 comprises a two-part base body 12 having belt drives 14 and 16, respectively. The two belt drives 14 and 16 have a drive belt 18 which, in the working position of the device 10, is pressed against the trunk of the tree, so that when the drive belt 18 is driven by a common hydraulic motor 20, the device 10 can Move up and down.

[0054] Furthermore, the device 10 additionally has a support wheel 22 which is held on the base body 12 via a connecting rod 24 . Via the transmission lever 28, the support wheel 22 can be rotated in the direction of the arrow A via the joint 26 into its working position, in which the support wheel bears against the trunk with pressure.

[0055] The two basic bodies 12 are fixedly connected to each other via an upper plate 30 and a middle plate 32 . The two belt drives 14 and 16 are here approximately at right angles to one another.

[0056] The tool bar 40 is fast...

Abstract

Described is a machine (10) for debranching living trees. The machine can move up and down the tree autonomously by means of a drive mechanism and has an upper cutting unit comprising three blades (48, 50) and below the upper cutting unit a lower cutting unit comprising two blades (46). The in total five blades (46, 48, 50) are arranged so that they cover the full girth of the tree. The two blades (46) in the lower cutting unit are horizontally offset so that their end portions can overlap. To move the machine (10) along the tree trunk there are two belt drives which press against the tree and are both driven by a single hydraulic motor (20). The upper cutting unit with its three blades (48, 50) can move horizontally as a whole, so that when the machine (10) is moved and encounters thicker or slightly bent parts of the tree trunk it can give way in order to prevent the bark from being damaged by the blades (46, 48, 50).

Description

technical field [0001] The invention relates to an apparatus for delimbing standing trees according to the preamble of claim 1 . Background technique [0002] Delimbing of standing trees, also called pruning or pruning, especially of conifers, is important both for the forest economy and for the timber and furniture industries. [0003] For wood processing a sawn trunk is sought. Considerable price gains are achieved through pruning, as it is possible to produce delimbed lumber. [0004] Debranching of pines and spruces is mainly considered, and once these trees are debranched, they continue to grow for many years and at the same time widen their diameter, however without the previously removed branches. The unpruned timber desired for furniture manufacture is thus provided when the tree is mature. [0005] Debranching of the tree is done only once. At the time of delimbing, the average diameter of the tree is about 30 cm, whereas in the final state during tree felling t...
