摘要

An excavation bucket incorporating an impact actuator assembly including a bucket body, a movable floor portion and an impact actuator provided between and mounted to the bucket body and the movable floor portion is described herein. The movable floor portion is longitudinally movable in the bucket body. When activated, the impact actuator assembly generates longitudinal impacts onto the movable floor portion to cause the repetitive longitudinal movements of the floor portion with respect to the bucket body. A forward edge of the floor portion is provided with tools such as teeth to penetrate hard soils.
