US Patent 9738008 Flail assembly with vanes

A flail assembly for use in debarking logs moving in a processing direction includes a debarking assembly having a shaft that is mounted for rotation above the logs moving in the processing direction. A flail having a fixed end is attached to the shaft. The flail has a length that defines an arc of rotation of the free end of the flail as the shaft is rotated. A housing is positioned adjacent the flail. The housing has a center line that is generally aligned with the processing direction, and a deflector vane which extends inwardly towards the arc of rotation of the free end of the flail. The deflector vane serves to direct bark chips that are cast upwardly by the flail away from the center line of the housing.
