A debarker is described, with converging blades, with hydraulic and/or penumatic control, to extract the bark from pruned branches or from branches and logs of felled trees. Small stumps obtained by dividing the pruned branches or the logs and branches of felled trees are left or not at rest during a certain time, after which they are processed in the debarker. The main part of this machine is a set of disks (3), radially driven by an hydraulic or pneumatic system (2), through which the stump is conveyed (9), axially pushed when entering the machine and pulled when going out by means of an automatic or manual feeding system (5, 6, 7, 8). The products thus obtained are clean stumps of wood and strips of bark (10) without any pieces of woody tissue. A clean debarking is thus obtained, with improvement of the operation of the downstream industries and better profitability of the bark extraction. Although specially conceived for the cork bark extraction, this machine may also be used for the extraction of other types of bark, for example, eucalyptus. |
