ABSTRACT:
An improved debarking apparatus, which includes a substantially, cylindrically shaped debarker head having a plurality of cutting blades to form its out peripheral surface, the debarker head mounted on a central shaft so that it may rotate freely on the shaft during the debarking process. In a first embodiment, the improved assembly would incorporate a pair of depth control bearing collars, mountable on an existing pillow block bearing, the bearing collar incorporating an adjustable shoe which includes an arcuate lower surface for making contact with the bark of the log that is being debarked, so as to select the precise depth of cut into the bark by the cutting blades of the debarker head. A second embodiment would provide a depth control bearing assembly which would be utilized in place of the pillow block bearing, the assembly including a roller bearing insert on each end of the debarker head, with the insert engaged upon the rotatable shaft, for accommodating a depth control bearing on the insert, with the depth control bearing likewise incorporating an adjustable shoe member on the lower portion of each of the bearing housings, the adjustable shoe including the arcuate lower surface for making contact with the bark of the log that is being debarked. The adjustable shoe would include an upper main body portion, having a pair of elongated slots therein so as to accommodate a pair of mounting screws between the adjustable shoe and the bearing collar.
