Abstract
The present invention relates to a conveyor system for log debarking and chipping. Specifically, a conveyor system for log debarking and chipping is provided that, in accordance with the present invention, conveys tree-length logs to and into a debarking drum and conveys debarked logs from the debarking drum to a chipper for chipping the debarked logs. The present invention provides a system adapted for long life, low maintenance and is adapted to withstand high impact loading while permitting high volume log processing.
Claims49
A log conveyor comprising:
- a frame constructed and arranged to withstand loading and impacts associated with high volume log processing;
- a subframe disposed on the frame constructed and arranged to withstand loading and impacts associated with high volume log processing;
- a trough disposed on the frame, said trough having inclined sides for containing and guiding logs transported by the conveyor;
- and
- a conveyor track having a plurality of links arranged in a closed loop movably disposed on the subframe, each of said plurality of links having a width sufficient to accommodate a breadth of at least one log, at least some of said links having at least one shoe member projecting therefrom thereby defining a beating surface upon which the logs are supported, said conveyor track being constructed and arranged to withstand loading and impacts associated with high volume log processing.

A log conveyor system comprising:
- a debarker infeed conveyor configured for placement at an entry end of a debarking drum for conveying logs to the debarking drum;
- a debarker outfeed conveyor configured for placement at a terminal end of the debarking drum for conveying logs from the debarking drum;
- a log loading conveyor disposed at a terminal end of the debarker outfeed conveyor for conveying logs from the debarker outfeed conveyor and for selectively receiving debarked logs from a remote source;
- and
- a chipper infeed conveyor disposed at a terminal end of the log loading conveyor for conveying logs to a chipper,
- at least-one of said debarker infeed conveyor, debarker outfeed conveyor, log loading conveyor, and chipper infeed conveyor having a track-chain conveyor track having a plurality of links arranged in a closed loop, each of said plurality of links having a width sufficient to accommodate a breadth of at least one log, at least some of said links having at least one shoe member projecting therefrom thereby defining a bearing surface upon which the logs are supported, said track-chain conveyor track being constructed and arranged to withstand loading and impacts associated with high volume log processing.

A log debarking and chipping system comprising:
- a debarker infeed conveyor;
- a debarking drum disposed at a terminal end of the debarker infeed conveyor for receiving logs from the debarker infeed conveyor and debarking the logs;
- a debarker outfeed conveyor disposed at a terminal end of the debarking drum for conveying logs from the debarking drum;
- a log loading conveyor disposed at a terminal end of the debarker outfeed conveyor for conveying logs from the debarker outfeed conveyor and for selectively receiving debarked logs from a remote source;
- a chipper infeed conveyor disposed at a terminal end of the log loading conveyor for conveying logs from the log loading conveyor;
- and
- a chipper disposed at a terminal end of the chipper infeed conveyor for receiving logs from the chipper infeed conveyor and chipping the logs,
- at least one of said debarker infeed conveyor, debarker outfeed conveyor, log loading conveyor, and chipper infeed conveyor having a track-chain conveyor track having a plurality of links arranged in a closed loop, each of said plurality of links having a width sufficient to accommodate a breadth of at least one log, at least some of said links having at least one shoe member projecting therefrom thereby defining a bearing surface upon which the logs are supported, said track-chain conveyor track being constructed and arranged to withstand loading and impacts associated with high volume log processing.
