Claim:
A belt cleaner device comprising a frame ( 3 ) extending in a transverse direction of a conveyor belt ( 9 ) and one or more cleaner heads ( 1 ) mounted on said frame ( 3 ), said cleaner head ( 1 ) having a scraping portion ( 18 ) on the upper end thereof which contacts with the surface of the running conveyor belt ( 9 ), whereby leavings struck on the belt are scraped off and fallen downward through a front wall ( 13 ) of said cleaner head ( 1 ) characterized in that: said frame ( 3 ) provides a support face ( 3 a ) on the upper surface thereof and a support hole ( 33 ) therethrough having its opening on said support face ( 3 a ), said cleaner head ( 1 ) provides a contact face ( 14 ) on the undersurface thereof corresponding to said support face ( 3 a ) so that said cleaner head ( 1 ) is supported so as not to be rotated about the running direction of the belt by contacting said contact face ( 14 ) and said support face ( 3 a ) with each other, and said cleaner head ( 1 ) being provided with an anchor ( 16 ) projecting downward from said contact face ( 14 ) through said support hole ( 33 ) so that said cleaner head is fixed to said frame ( 3 ) by said anchor ( 16 ) having been inserted through said support hole ( 33 ) due to downward pressure applied to said anchor ( 16 ), said anchor ( 16 ) including a leg ( 16 b ) and a nail ( 16 a ) bent from the end of said leg ( 16 b ). said leg ( 16 b ) being formed with an elastic resilient material integrally with said cleaner head ( 1 ), wherein said anchor ( 16 ) is fixed to the frame ( 3 ) in such a manner that said leg ( 16 b ) having resiliently deformed during insertion of the nail ( 16 a ) and the leg ( 16 b ) with downward pressure through said support hole ( 33 ), has been restored to its original shape after passage of the nail ( 16 a ) out from the hole ( 33 ) and is in engagement with the undersurface of the frame ( 3 ), and wherein said cleaner head ( 1 ) further has a concave ( 21 ) in at least one of said front wall ( 13 ) and a rear wall ( 15 ) opposite thereto, said concave ( 21 ) having a strike seat ( 22 ) at the bottom thereof which forms a flat plane parallel to said contact face ( 14 ) and is positioned near a center of gravity of the cleaner head ( 1 ), whereby said anchor ( 16 ) has been pressed and inserted through said support hole ( 33 ) by striking said strike seat ( 22 ) with a hammer or the like to produce said downward pressure.
