Image Number 8 for United States Patent #5746302.
Conveyor cleaning assemblies are disclosed for cleaning endless conveyors such as for conveyor belts or chains. Each assembly includes a cleaning head which carries brushes for engaging one or more adjacent surfaces of the conveyor and a head support for holding the cleaning head in a fixed position adjacent a predetermined portion of the conveyor path. The cleaning head is engaged on the head support by sliding engagement movement in a direction generally parallel to the direction of movement of the conveyor that is contacted by the cleaning head, with the cleaning head and the head support having abutment stops to limit this engagement movement. Accordingly, the friction forces of the conveyor hold the cleaning head in position on the support without requiring any further attachment devices. In one embodiment, a cleaning head with brushes and a scraper is so mounted for cleaning a conveyor belt. In other embodiments cleaning heads with brushes are so mounted on opposites sides of large conveyor chains.
