Abstract:
Lubricating oil supplied to the annular antifriction bearing mounting a rotary ring log barker ring on ring-mounting means, and lubricating oil supplied to air seals for a rotary ring log barker annular air plenum chamber is returned to an annular oil-collecting chamber in the inner periphery of the rotary ring. From such oil-collecting chamber oil is scavenged by a stationary scoop tube in the upper portion of the rotary ring-mounting structure and drained by gravity to a reservoir from which it may be pumped for recirculation through the components of the barker requiring lubrication.
Abstract:
The disclosure herein describes improvements to a log debarking machine which consists in allowing the mounting of six debarking tools on the machine rotor which has a central log-passing opening of eighteen inches in diameter. The rotor is arranged with a series of bearing seats for receiving and supporting the tool spindles. The improvements further include a cleaning knife for cutting the bark fiber which adhere to the tools.
Abstract:
A debarking tool for a rotor type debarking machine is provided with an arcuate body having a substantially sharp log engaging climbing edge portion so arranged thereon and positioned closely adjacent a cutter member on the adjacent free end of the arcuate body as to aid the logs in quickly deflecting the debarking tool out of the path of the logs during rotation of the tool with the ring rotor.
Abstract:
An annular barking rotor has a hub portion rotatably supported by a concentric anti-friction bearing and supports a plurality of radially pivotable barking arms each biased by an air motor mounted on the rotor and connected to an annular air chamber within the rotor. Air is supplied to the chamber and motors through a set of sliding air shoes, and the pressure of the air is controlled by a series of pilot operated valves, relay exhaust valves and regulating valves actuated by controls located at a remote console. Pilot operated diaphragm exhaust valves are carried by the rotor for connecting the air chamber directly to atmosphere and are actuated by a pulse of pilot air supplied through another air shoe connected to the main air supply through a pilot operated valve controlled by a valve also located at the console.
Abstract:
The rotary ring of a log barker has a flaring mouth carrying limb-cutting bits in radial planes. Hooked ends of swinging arms rotate around a log as it is moved lengthwise to scrape off the bark. Bark and limb pieces fall into a hog having stationary shearing bars cooperating with rotary shearing bars carried above a plate rotating about a vertical axis. Hogged material dropping through apertures in the plate is swept out of the casing by vanes carried by the rotor.
Abstract:
Disclosed herein are embodiments of batch-style bottom-discharge rotary debarkers for removing bark from a batch of logs in a bin and discharging debarked logs from a bottom of the bin. In some embodiments, the bin includes four walls and an opening in its bottom. In some embodiments, the debarkers include a plurality of rotors, a plurality of chutes, and a plurality of conveyor belt systems for carrying bark and logs away from the bin. In some embodiments, the debarkers include an internal gate which can be moved between a debarking configuration and an unloading configuration.
