Document Type and Number:
Japanese Patent JP7028822
Kind Code:
B2
Abstract:
To save time and effort for machining by a crushing member and reduce loads applied to a bolt for fastening as much as possible.SOLUTION: A crushing device crushes an object to be machined, by making a crushing member 20 arranged at a peripheral edge of a discoid rotor 12 that rotates in a crushing chamber 11 apply impact onto the object to be machined. On a surface of the rotor 12 is formed a crushing member storage concave part 16 for fixing the crushing member 20 with an interval in a circumferential direction. The crushing member 20, in which a convex part 21 for insertion that is inserted into the crushing member storage concave part 16 and has a female screw part 21a to be fastened with a bolt 23 for fastening formed therein and a crushing part 22 led to the convex part 21 for insertion, which collides with the object to be machined to crush the object to be machined are integrally formed, can be fastened with the bolt 23 for fastening from a rear surface of the rotor 12, with the convex part 21 for insertion inserted into the crushing member storage concave part 16.SELECTED DRAWING: Figure 1
