Claim:
A belt cleaner including one or more cleaner units mounted on a frame extending in a transverse direction of a conveyor belt, whereby leavings stuck on a belt surface are scraped off by a scraping portion provided at a top portion of said cleaner unit characterized in that: said cleaner unit ( 6 ) comprises a support plate ( 8 ) providing said scraping portion ( 7 ), an upper resilient block ( 9 ) supporting resiliently a lower portion of said support plate, a lower resilient block ( 10 ) supporting resiliently a bottom of said upper resilient block ( 9 ), and a rigid plate ( 15 ) provided between said upper resilient block ( 9 ) and said lower resilient block ( 10 ), said rigid plate ( 15 ) being arranged along a sloping plane (HP) that rises in a direction (B) toward the rear of the cleaner unit and which follows a belt running direction, wherein said support plate ( 8 ) is supported by said upper resilient block ( 9 ) in such manner that said support plate ( 8 ) is held in a forward leaning posture along a tilted plane (VP) inclining towards a front direction (F) of the cleaner unit which opposes against a belt running direction (X) with respect to a vertical line (V) perpendicular to the belt surface, wherein said upper resilient block ( 9 ) includes hypothetical pivot axis ( 21 ) and is constituted to be deformed resiliently when a pushing force in said belt running direction is applied to said scraping portion so that said support plate ( 8 ) shifts its posture to an upright posture from said forward leaning posture about said hypothetical pivot axis ( 21 ) to lift up said scraping portion ( 7 ), and wherein said lower resilient block ( 10 ) is constituted to be deformed when a further pushing force in said belt running direction and/or in a downward direction is applied to said upper resilient block ( 9 ) which is compressed or deformed by said support plate ( 8 ) shifted to said upright posture so that said lower resilient block ( 10 ) allows said upper resilient block ( 9 ) to move downward in response to said further pushing force.
