Debarker for debarking tree trunks

The invention relates to a debarking device for debarking tree trunks.

Sas debarking tree trunks is very time-consuming when using the tools previously known for this purpose and laborious work. Today, tree trunks are usually debarked by hand using knives Debarking mode is very stressful for workers and given today's labor shortage very uneconomical. Debarking a large number of tree trunks in a short time is therefore not possible possible.

109839/0018

Ee also debarking machines are known in which the tree trunk to be debarked around its longitudinal axis by means of of a drive is rotated. Sin or more knives attack the circumference of the rotating tree trunk and cut them Tie off the rotating tree trunk in the circumferential direction. However, the knives do not adapt to any fluctuations in the diameter of the tree trunk. Hence with these known machines not only lifted the bark but also a lot under the hand! This results in an uneconomically large loss of wood. In addition, these known machines require a very large drive power, so that overall they are very uneconomical to operate.

The invention is based on the object of providing a debarking device for debarking tree trunks, which with a simple structure and economical production one has great debarking performance, easy to use and in Operation is robust, economical and safe, with which there is no loss of wood, and which in their design different operating conditions, for example debarking standing trees or tree trunks floating in the water, is customizable.

This object is achieved according to the invention in that the device has at least one paring knife with two at an angle

109839/0018

to each other and with respect to a center line of the knife has symmetrically extending sclineid edges, which made of elastic-flexible sheet metal and is more curved transversely to the center line than the outer surface of a tree trunk to be debarked and wrapped around the tree trunk resiliently, and which paring knife on its convex one Outer surface is attached to a mounting device.

The device according to the invention has at least one paring knife which at least partially encloses the outer circumference of the tree trunk to be debarked and lies tightly against the tree trunk. In the case of thin tree trunks, a single paring knife is sufficient to completely enclose the circumference of the tree. If the device according to the invention is to be used for debarking thicker tree trunks, it is advantageously equipped with several paring knives, which then encompass the circumference of the tree trunk to be debarked and, if necessary, partially overlap. By three (eoksförmige design of the peeling blades v-ird achieved an excellent peeling effect. In order to replace dii child by means of the peeling blade of a tree trunk, is sine relative movement

sweat the peeling knife and the tree trunk required Either the holding device can be held with the paring knives and the tree to be debarked * trunk can be moved relative to it, or vice versa, the tree trunk can be held and the holding device be moved with the paring knives · Trelbwalzen or Xdriver Sets «One movement of the fixture β · Β «can take place in such a way that the holding device is attached to a longitudinal guide, for example a sole * nenfOhrung, guided and dragged by means of a drive or driven over a pool plant. You triangular ~ mlgen paring knives detach the bark from the tree trunk during the relative movement of the tree trunk and paring knives and slide between the bandage and the tree trunk. During the relative movement, the tip of each triangular first penetrates Paring knife under the Eaumrinde and loosens it in the area of the tip. In the course of further movement then the bandage is also peeled off along the entire cutting edge of the paring knife · Ba the paring knife in unloaded State a greater curvature than de curvature the circumference of the tree trunk, it is guaranteed that the peeling

knife close to the tree trunk. The main material for the paring knives is steel. In order to facilitate the penetration of each paring knife under the bark, and in order to improve the cutting effect, the debarking device according to the invention is advantageously so atis formed that a relatively sum paring knife in the radial direction outwardly extending cutting blade to soles the bark directly or indirectly When the tree trunk moves relative to each other and the paring knife and son's razor blade, each cutting blade slits the cattle in front of the paring knife, thus enabling better penetration of the paring knife and a symmetrical detachment of the bark with respect to the symmetry line of the paring knife.

An advantageous embodiment of the debarking device according to the invention is given by the fact that the paring knife on its convex outer surface in the area of its symmetry line is attached to an arm, which in turn is pivotably articulated on the mounting device and in an exemption and by means of spring force in a working position on the to be debarked Tree trunk can be pressed. In this embodiment, the paring knives can be folded out of the tree trunk area when not in use. This enables easy manipulation. In addition, the paring knives can be easily checked and serviced in this way. With this configuration, the peeling

In addition, they are elastically flexible themselves. on this way is an automatic adjustment to bumps the circumferential area of the trunk during the debarking process guaranteed · With this configuration, the sons' blade can advantageously be detached from the arm and adjustable so that it protrudes in front of the tip of the sweet paring knife. The son's eidblade is then put together with the paring knife in the working position bftw, folded into the release position

Advantageously, the debarking device according to the invention is designed so that a spring is arranged on the holding device in the region of each paring knife is, which is designed as an elastic bending rod or leaf spring describing an arc,

Swiveling the pressure spring out of the working position in the release position is in kürseater time with a single hand movement possible. Swiveling into the working position can also be accomplished quickly will.
