<P>PROBLEM TO BE SOLVED: To provide a crushing rotor allowing bit arrangement to be easily changed. <P>SOLUTION: A plurality of rings 3 with a circular ring shape having a crushing bit 32 at an outer circumferential part around a rotatably provided rotary shaft 1 are arranged in a line in an axial direction. Stoppers 4a, 4b at both end parts in the axial direction of the line of the plurality of rings 3 regulate relative movement of the plurality of rings 3 in the axial direction relative to the rotary shaft 1. A slider 2 is provided between the rotary shaft 1 and the plurality of rings 3 so as to be slidable in the axial direction relative to the rotary shaft 1 and the plurality of rings 3. Sliding of the slider 2 in the axial direction selectively switches a state in which splines 24, 35 provided between the slider 2 and the plurality of rings 3 so as to be mutually engaged with each other are engaged to regulate the rotational movement of the plurality of rings 3 in the circumferential direction relative to the slider 2 and a state in which the engagement of the splines 24, 35 is released to allow the rotational movement of the plurality of rings 3 in the circumferential direction relative to the slider 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
