CONVEYOR BELT STRIPPER Abstract A conveyor belt cleaning assembly (10) includes an array of stripper blocks (24) which are coupled to a rigid crossbar (22) by resilient connecting arms (26). The resilient connecting arms are characterized by high com- pressive strength, but exhibit a structural collapsing response to off center deflection forces which exceed a predetermined load level. The collapsed connecting arms thus provide a reduction in length of the stripper assembly in response to a belt reversing condition. One side (26A) of each connecting arm has the ability to collapse in response to a relatively low deflection force and the other side (26B) has the ability to deflect and withstand sub- stantial compression loading without collapse. The body of each connecting arm is intersected by a large aperture (44), thereby defining a forward collapsible wall and a load bearing rear wall. A reduction in length of the entire connecting arm is achieved by collapsing the forward wall in response to the loading imposed by engagement of the stripper block against a reverse moving conveyor belt.
