An attachment is used on a bin sweep of a type having inner and outer sections of auger flighting and a backboard along the outer section of flighting. The attachment includes a shield that extends along the back of the inner sectio n of flighting to control the accumulation of material around the inlet to a loading auger with which the bin sweep is used. The shield is attached to the pivot mount for the bin sweep with a coupling allowing the movement of the shield with respect to th e inner flighting section. It is connected to the backboard of the outer flighting section using a flexible joint that allows substantially universal movement of the shield on the backboard. This allows the flexing of the bin sweep as necessary at the universal joint between the inner and outer flighting sections and substantially reduc es the accumulation of material in a pile between the inner end of the backboard an d the loading auger.
