The invention relates to a bark peeling machine, preferably for mobile use with Paring knife driven by an internal combustion engine by means of an eccentric, which is attached to an elastic with the Motor housing connected, due to the inclined arrangement of the eccentric on the motor shaft stub a Longitudinal and transverse movement and a wobbling movement executing plate is attached, according to patent 1171 595, the further development being a particularly useful storage and holding of the Paring knife has the object.

In the bark peeling machine according to the main patent, the peeling knife is attached to holding arms, which in turn oscillate in different planes with the one driven by the internal combustion engine Plate are connected. To keep the paring knife in the spread position, the arms are resiliently supported against a fixed point. However, this holder of the paring knife is not sufficient in all Share the requirements of practical operation. In addition, the vibrating plate can with the attached knives come to a standstill at high speeds while the whole system rocked so that no satisfactory knife movement is achieved.

According to the invention, approaches are on the underside of the plate moved by the internal combustion engine arranged for the articulation of crossed arms, the eyes at their free ends for reception of threaded pins of the brackets for the paring knife. The threaded pins of the knife holders are rotatable in the holes of the eyes and z. B. can be determined via wing nuts and notches. By the arrangement of crossed When arching the paring knife, the middle part of the paring knife always remains at approximately the same distance from the arms Vibration plate, while the outer ends of the knife curvature are stronger or weaker move down or up.

In the drawing, an embodiment of the invention is shown schematically, namely shows

F i g. 1 is a side view of the bark peeling machine,

F i g. 2 the front view and

F i g. 3 the top view.

The internal combustion engine is on the fixed plate 4 1 arranged, wherein a bracket 2 and a handle 3 are available for guiding the device. Above Rubber-to-metal elements 8, 9, a vibrating plate 6 is arranged below the fixed plate 4, the movement of which takes place from the crankshaft 5 with the interposition of the inclined eccentric.

Contrary to the eccentricity is on the stub shaft 5 of the internal combustion engine 1, for example between A counterweight 7 is arranged on the plates 4 and 6 and is firmly wedged to the stub shaft 5. On the Underside of the moving plate 6 lugs 12 are arranged, in which bolts 13 the crossed Arms 10, 11 are mounted. The free ends of these arms 10, 11 have holes provided with holes 10 ', 11', threaded bolts 14 'of the brackets 14 for the paring knife 15 passed through their bores are. Wing nuts 16 give the possibility of the brackets 14 according to the respective requirements to rotate and to determine in notches 17, so that the curvature of the paring knife 15 from the start can be adjusted to the different curves of the logs to be peeled. By the articulated mounting of the arms 10, 11 on the plate 6 is then still a precise concern during operation of the paring knife 15 given to the trunk curve, the middle part of the knife in his Distance from the plate 6 remains almost constant, while the knife ends to change the Knife arch can be moved up and down. The arms 10, 11 can be cranked at the point of intersection be, or it is possible to move the bearings 12 so that the straight arms laterally pass each other.

In the context of the invention it is also conceivable for the curvature of the paring knife 5 to be constant from the start and to forego the adjustability by means of the wing nuts 16 and notches 17.

Claims (2)

Patent claims: 1. Bark peeling machine, preferably for mobile use, with an internal combustion engine 509 518/116 by means of an eccentric driven paring knife, which is attached to an elastically connected to the motor housing, due to the inclined arrangement of the eccentric on the motor shaft stub a longitudinal and Transverse movement and a wobbling movement executing plate is attached, according to patent 1 171 595, characterized in that on the underside of the plate (6) moved over the internal combustion engine (1) lugs (12) for the articulated Storage of crossed arms (10,11) are arranged, the eyes at their free ends (10 ', 1Γ) to accommodate the threaded pin (14') of the brackets (14) for the paring knife (15) exhibit. 2. Bark peeling machine according to claim 1, characterized in that the threaded pin (14 ') of the knife holders (14) in the holes of the eyes (10', 1Γ) rotatable and z. B. over Wing nuts (16) and notches (17) can be determined. Considered publications:
