Abstract

The invention is directed to a conveyor operated by idler members driven in rotation by a motor (16) which includes a pair of spaced apart flexible elements connected to the idler member and having an endless extension. Refuse transporting blades (8) are in engagement with the pair of flexible elements. The flexible elements are belts (6) having a toothed face (6a), and the idler member are bell-shaped bodies (7) each having a shaped support (17) parallel to a respective rotation axis (11a), an annular border (18) extending radially from the shaped support (17), and circumferentially spaced pins (19) for meshing with the toothed face (6a) of the belts (6). The pins (19) are fixed to the annular border (18) and tangentially overlie the shaped support (17) which supports a portion of the pins (19) in a resting condition.
