Abstract
An elongated infeed frame supporting a debarking unit has a trailer-like structure so that it is readily portable and can be transported into a logging or debarking area. An off-bearing frame is also portable for easy transportation to the area. Each of the infeed and off-bearing frames has structure providing side loading and unloading, respectively, so as to be worked in a minimum area. Also, each of the two frames has outriggers for selectively supporting them on uneven ground and at desired planes and at desired angles relative to each other. Hold-down and guiding mechanism are provided for efficiently directing the logs into and out of the debarking unit.
Claims16
A portable log debarking apparatus comprising
- (a) an elongated infeed frame having road engaging wheel support means at one end thereof,
- (b) a hitch on the other end of said frame arranged to be connected to a pulling vehicle for movement of the frame to a site of logs to be debarked,
- (c) a power driven debarking unit on said frame adjacent one end,
- (d) a power driven conveyor on said infeed frame operating toward said debarking unit, (e) said conveyor being arranged to feed logs deposited thereon longitudinally into said debarking unit,
- (f) one side of said infeed frame being unobstructed along a greater portion of said conveyor to allow side loading of logs onto said conveyor,
- (g) stop means on the other side of said frame from said unobstructed side for limiting the loading travel of logs when side loaded onto said conveyor,
- (h) and an off-bearing frame arranged to receive logs discharged from said debarking unit,
- (i) said off-bearing frame having free standing support on the ground whereby also to be portable.
