Patent ID: 6962178

Claim:
A tree processor for delimbing and cutting to a desired length of at least one workpiece simultaneously, the tree processor comprising: an elongate rigid support member having first and second opposite ends, a coupling means mounted to an upper side of said support member for mounting of said support member to a work arm wrist coupling, selectively actuable first and second pairs of clamping arms mounted to said first and second ends of said support member, said first and second pairs of clamping arms mounted laterally across and depending downwardly from said support member and selectively actuable between open positions for entry and exit of workpieces to and from between said pairs of clamping arms, and closed positions clamped around workpieces and when in said closed positions thereby defining a workpiece processing pathway extending longitudinally under said support member and said processing pathway having lateral boundaries and a lower boundary, said pairs of clamping arms when in said closed positions cradling the at least one workpiece longitudinally under said support member, a pair of selectively actuable drive wheels mounted on selectively actuable first pivot arms pivotally mounted to said support member so as to dispose each drive wheel of said pair of drive wheels downwardly of said support member and laterally spaced apart by a selectively adjustable lateral distance apart on said lateral boundaries of said processing pathway for sandwiching between said pair of selectively actuable drive wheels the at least one workpiece when in said processing pathway, said pair of selectively actuable drive wheels for engaging and urging the at least one workpiece in substantially linear translation along said processing pathway so that the at least one workpiece in said processing pathway is delimbed by at least one of said first and second pairs of clamping arms cradling the at least one workpiece in said processing pathway, a selectively actuable upper drive means mounted to an underside of said support member so as to extend into, for urging the at least one workpiece along, said processing pathway, a selectively actuable lower drive means rotatably mounted to a lower end of a second pivot arm pivotally mounted to said support member for translation of said lower drive means between a retracted position retracted from under said processing pathway and an engaged position wherein said lower drive means extends up into, from under, said lower boundary of said processing pathway to engage and urge a lower surface of the at least one workpiece along said pathway, a selectively actuable sawing means mounted to said first end of said support member for lateral sawing in a sawing plane laterally through the at least one workpiece when in said pathway.
