<p><P>PROBLEM TO BE SOLVED: To provide a crushing tool and a hydraulic crushing device capable of easily crushing a crushed object and capable of being easily disassembled. <P>SOLUTION: The crushing tools 57 and 67 of the hydraulic crushing device 1 are attached to pistons 53 and 63 of hydraulic cylinder mechanisms 50 and 60 operated by hydraulic pressure of oil delivered from a hydraulic pump mechanism 20, and are protruded to crush the crushing object W when the hydraulic cylinder mechanisms 50 and 60 are operated, and include tapered tip parts 58a and 68a capable of being stuck into the crushing object W, and flanged parts 58b and 68b formed on base ends of the tip parts 58a and 68a and recessing the surface of the crushing object W by being abutted thereon. The tapered tip parts 58a and 68a include tip side conical parts 58c and 68c, and base end side truncated conical shape parts 58d and 68d continuously connected to the conical parts 58c and 68c, and apex angles of the conical parts 58c and 68c are larger than apex angles of the truncated conical shape parts 58d and 68d. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
