Secondary system for cleaning a belt running between conveyor pulleys comprised of a frame bar on which cleaning blades are mounted, two bracket assemblies to which the frame bar is adjustably mounted, and an adjustment system mounted on the external sides of the bracket assemblies. Bracket assemblies each can include a pair of slotted arms over which two or more clamps are joined together. Each bracket assembly can include an inner tube member that telescopes into two outer tube members and an upper member that can be adjustably clamped to the inner tube and a lower tube member to which the frame bar is mounted and attached to the upper member by the adjustment system. Frame bar and bracket assemblies have rectangular cross-section so that when mounted to each other, rotational movement of frame bar about its longitudinal axis is prohibited. This rotational prohibition is independent from the adjustment system. |
