Abstract
A paddle for a reclaiming drum may include a block of material configured for attachment to a leading edge of a flighting supporting a cutting bit on the reclaiming drum, and the block of material may assist in breaking up and mixing material removed from a surface by the cutting bit as the reclaiming drum is rotated and moved into the surface. The paddle may include two ear portions protruding from opposite sides of a flat, centrally-located, aft-facing surface of the block of material, each of the ear portions including an inwardly-facing chamfered surface configured to interface with an outwardly-facing, leading edge chamfered surface of the flighting such that a gap is maintained between a flat leading edge surface of the flighting located in between the outwardly-facing chamfered surfaces and the flat, centrally-located, aft-facing surface of the block of material when the block of material is attached to the flighting.
