FIELD: loose material storage. SUBSTANCE: invention relates to means of cleaning inner surfaces of hollow articles and breaking bridges of caked material formed in process of storage. Proposed device contains hollow drive shaft made in form of housing and installed for rotation in hole of wall or in narrow neck of container. It has at least two working members made in form of elongated flexible members and device for moving flexible members to different sides. Said working members freely pass through space of bushing being fixed in bushing for combined rotation. Longitudinal displacement of working members into container space is limited by stop mechanism. Device for moving working members from each other is furnished with distance check means graduated for setting angle of separation of working members. Invention makes it possible to check degree of bridge breaking and container cleaning in process of operation. EFFECT: improved reliability and efficiency and convenience in use. 4 cl, 3 dwg
