ABSTRACT:
An improved adapter and lip segment for an ore excavation bucket wherein the adapter can be coupled to an excavation tooth. The adapter is streamlined to minimize the weight of the lip segment and adapter combination yet the wear on the lip is minimized to extend the life of the operation of the lip and to minimize maintenance costs of the bucket. Each lip segment has a pair of pockets on the upper and lower surfaces thereof. The pockets are adapted to receive the ends of the pair of legs on each adapter, and in one embodiment, the adapter is coupled to the corresponding lip segment by a pin which extends through aligned holes in the legs of the adapter and the lip segment. The pin can be a spring pin or a wedge-shaped pin. In another embodiment, the lip segment has a pair of spaced, aligned holes and one of the legs of the adapter is alignable with the holes of the lip segment. A wedge block and a wedge key are forced into the aligned holes. The adapter has shoulder shrouds which protect the lip segment from wear due to attrition of the ore flowing over the lip.
