摘要： PROBLEM TO BE SOLVED: To enable large crushing and fine cutting of an object to be crushed by a same crusher by finely cutting the object to be crushed taken in the crusher by crushing by the crushing teeth of a crushing drum rotating and delivering from the crusher. SOLUTION: A crusher is pivotally mounted by the claw 18 and the pin 6 of a bucket-like frame 1 mounted pivotally by pins 30, 30 on the edge of the rotating arm A of a civil engineering machine to sandwich and crush the object C to be crushed such as a concrete lump between the crushing claws 4 of an arm 5 inclined by a hydraulic cylinder 9 to be taken in the crusher. The crushing drum 14 radially forming crushing teeth 13 is rotated by a hydraulic motor 12, the object C to be crushed is finely cut between the inner wall faces 8 of a frame 1, and delivered from the delivering outlet of the frame 1. Thereby large crushing and fine cutting of the object C to be crushed can be performed by the same crusher. When a part of the crushing drum 14 is projected and delivered from the delivering outlet 3, a base or the like is cut by the crushing drum 14 to be flattened.

摘要： PROBLEM TO BE SOLVED: To attract metallic materials in wastes, by fixing a magnet at the bottom to apply or disconnect the magnetic force at the cab and forming fixed breaking disks at the bottom plate of the body and pivotting movable breaking teeth at the body and providing shearing cutters in the breaking disk and the breaking tooth. SOLUTION: Fixed breaking disks 11 are formed at both right and left side faces of the scoop board 10 of a bucket and movable breaking teeth 13 are pivotted to shafts 12 so as to be set opposite to the fixed breaking disks 11. The movable breaking teeth 13 are connected to hydraulic cylinders 14 to break concrete blocks or the like and transfer waste materials by holding them between the fixed and movable breaking disks and teeth. And shearing cutters 15, 16 for reinforcements are arranged near the pivot shafts of the fixed breaking disks and the movable breaking teeth to cut off long reinforcements or the like. In this way, not only concrete waste materials can be scooped but also metallic wastes like reinforcement chips can be attracted, and hence, the capacity of the bucket can be increased.

摘要： PROBLEM TO BE SOLVED: To conduct the holding action of a subbase course, etc., and percussion and impulse action by pivoting a ripper main body curved in an inverted semicircular shape to a support member, to which a crushing arm is connected continuously, by a pivotal shaft section at the front end of a whirling arm for a civil engineering machine. SOLUTION: The substrate 1b of a rippe main body 1, which is formed in an inverted semicircular shape and to which a sharp edge 2 is formed, is pivoted to a support member 4 mounted at the front end of a whirling arm 6 by a pivotal shaft 3. Not only a pointed shape but also a spatula-like shape that a subbase course X is easy to be peeled may also be used as the sharp edge 2. An arbitrary curved shape such as a U shape, a chevron shape, etc., is selected as the main body 1. A crushing arm 7, which is faced oppositely to the curved section of the main body 1 and in which an impulse horn 8 is formed in the front and striking edges 9, 10 in the downward direction, is integrally connected continuously to the support member 4. The subbase course X, etc., are peeled by the sharp edge 2, and the subbase course X, etc., are percussed and broken by the striking edges 9, 10 worked while using the pivotal shaft 3 as a support, and struck against a bedrock, etc., and destroyed by the impulse horn 8. Accordingly, the sawing and dropping works of fragmented stones and column jointing rocks of the subbase course, etc., can be conducted.
