SOLUTION: A bucket body 7 swingably installed on the tip end of an arm of an civil engineering machine and having an opening 8 for charging a raw material is provided with a swingingly-opened/closed movable lid. The crushing lid 12 is opened/closed by lid-interlocking opening/closing means 50, 13 in interlock with the swinging motion of the bucket body 7. The raw material charged through the opening 8 is crushed with a resilient plate and a rotor installed in the inside of a movable wall. COPYRIGHT: (C)2005,JPO&NCIPI
