PURPOSE:To rapidly treat broken objects by a bucket by a method in which a breaker is rotatably attached to a box-type bucket body having an opening on its front side, and objects are broken into small pieces between the breaker and the bucket body by extending or contracting an liquid-pressure cylinder. CONSTITUTION:When the liquid-pressure cylinder 18 of a bucket 2 mounted on a power shovel or back hoe is extended, a breaker 16 is turned and objects are broken into small pieces by compressive force and shearing force between a fixed bit 32 and a movable bit 34. After the breaking work, the liquid-pressure cylinder 18 is contracted and broken objects are loaded on a truck, etc., by the bucket 2. Thus, breaking concrete structures or coal, loading the broken objects, and excavation can be attained simply by mounting the bucket 2 on a construction machine. |
