Abstract

A chipping machine includes a debarking assembly, a chipper assembly, and a log advance system to conveys logs through the chipping machine and into contact with the debarking assembly and chipper assembly. A rotating chipper disk cuts chips from the log. A housing encloses the chipper disc and includes a spout that provides an exit path for chips out of the housing. The chipper assembly includes a first path for collecting bark and directing bark out of the machine. A second path that is separate from the first path collects trash and directs the collected trash to first path and out of the machine. An inlet of the second path is an opening formed in a base of the housing. The second path includes a chute onto which trash falls and then slides under the force of gravity to the first path.

Claims (9)

1. A housing assembly adapted for use on a chipping machine having a base for surrounding a lower portion of a rotating chipper disk with a chipper disk upper portion, a chipper disk lower portion, at least one chipper knife assembly, and a centerline, said housing assembly further comprising:

a hood having:

a stationary portion configured for removable attachment to the base to form a housing for substantially enclosing the chipper disk;

an access opening formed in the stationary portion for providing access to an inside of the housing;

an access door covering the access opening and adapted to be moved between an open position where the access door is uncovered and a closed position where the access door is covered; and

a parting line disposed at a junction of the base with the hood,

wherein the hood and the access door are adapted to substantially surround the chipper disk upper portion while the base substantially surrounds the chipper disk lower portion; and

wherein the stationary portion comprises a first side, a second side opposite and spaced apart from said first side, and a third side connecting the first side and the second side, and wherein the stationary portion is sized such that the parting line is disposed vertically higher than the centerline of the rotating chipper disk.

2. The housing assembly of claim 1 further comprising said base and a chute having an inlet formed in the base of the housing assembly on an upstream side of the chipper disk and an outlet, wherein the inlet is sized and configured to collect trash within the housing assembly and the chute is configured to automatically carry the trash out of the housing assembly under a force of gravity.
