Abstract
A crusher bucket includes a bucket body (70) and a crushing lid (76) provided on the bucket body. The crushing lid is capable of being opened and closed relative to the bucket body. A material feed rate adjusting mechanism is provided on the bucket body (70) and/or the crushing lid (76) to allow raw material scooped up into the bucket body (70) to be fed into a crushing chamber (70a) in a predetermined amount at a time. Hammers (74) are disposed on the outer periphery of a rotor driven rotationally by a power drive device to strike and break the raw material fed into the crushing chamber (70a). A repulsion plate (77) is provided on the crushing lid (76) to collide with the raw material struck by the hammers (74). The material feed rate adjusting mechanism is preferably a weir (72) provided on the bottom wall of the bucket body (70).
