Abstract:
A device for cleaning an endless conveyor, comprising:first and second sheaves spaced along a longitudinal axis and rotatably supported above a supporting surface, each sheave being rotatable about a corresponding axis transverse to the longitudinal axis and including a radially outer surface; an endless brush belt extending about the radially outer surfaces of the sheaves and having an outer surface engagable with the endless conveyor, the endless brush belt traveling about the sheaves in response to rotation of the first sheave; a drive structure operatively connected to the first sheave for rotating the first sheave; a tension mechanism operatively connected to one of the sheaves for adjusting the spacing therebetween and providing a tension on the endless brush belt; and a clutch mechanism operatively connected to the tension mechanism, the clutch mechanism releasing the tension mechanism from the one of the sheaves so as to prevent the placement of additional tension on the endless brush belt in response to the tension exceeding a predetermined maximum tension.
