If the blade is worn by use, remove the plug-like block from the rotor, remove the blade from the blade holder, and make an integral multiple of 90 degrees to the blade mounting surface of the blade holder, the center axis thereof. When the direction of the blade is changed around and a new vertex and two cutting edges connected to it are projected from the peripheral surface of the rotor and the blade and plug-like block are fixed again in the original state, the sharpness of the blade is improved. Is new, it is possible to continue the crushing work, if the apex of the front surface of the blade is completely worn, remove the blade from the blade mounting surface of the blade holder, can be used by reversing the front and back, At least four vertices of the blade When Worn is the plug-shaped block body detached from the rotor, further remove the blade and the wear from blade holder can be replaced with a new one. Thus, one blade can be used until at least all four corners are worn, and the life of one blade can be extended.

ることが出来る。By forming the blade mounting seat in the chord direction of the rotor as described above, both ends of the blade mounting seat are open, and the positioning of the blade with respect to the rotor circumferential surface is performed by mounting the blade holder on the rotor circumferential surface. The blade mounting seat can be easily machined into the rotor, and the front portion of the blade mounting seat is covered with the plug-shaped block so as to be crushed during use. The cutting resistance of the object to be crushed can be reliably reduced without entering the blade mounting seat. In the invention according to claim 2, in addition to the effect of the specific invention, the stopper for preventing displacement prevents the blade holder from being displaced on the blade mounting seat at the time of use and prevents the blade holder from moving relative to the blade mounting seat. The blade holder can be positioned at a predetermined position. Further, when the type of the crushed object is different, the entire rotary blade, that is, the above-mentioned throw-out tip, blade holder, stopper and stopper-shaped block body are removed from the rotor, and the one corresponding to the type of the crushed object.
