SELF-PROPELLING CRUSHER AND METHOD FOR REPLACING ROTARY TEETH OF SELF-PROPELLING CRUSHER

PROBLEM TO BE SOLVED: To facilitate the replacement of monolithic rotary teeth at the time of abrasion while achieving cost reduction as the monolithic rotary teeth. SOLUTION: In a self-propelling crusher 1 wherein a shearing type crushing device, which has a plurality of rotary bodies 23A, 23B respectively equipped with rotary shafts 20A, 20B arranged in an almost horizontal direction and a plurality of the monolithic rotary teeth 21A, 21B fixed to the rotary shafts and a plurality of the fixed teeth 24A, 24B arranged on the outer peripheral sides of the rotary bodies, is disposed on one side in the longitudinal direction of a track frame 7 and the object to be crushed received in a hopper 2 is crushed and the crushed matter is fed out by a conveyor 6, a plurality of the rotary bodies 23A, 23B are arranged so that the rotary shafts 20A, 20B are arranged almost along the longitudinal direction of the track frame 7 and a drive device 11 and the crushing device 3 are arranged so that the end part on the side opposite to the drive device of the crushing device 3 faces outwardly on one side in the longitudinal direction of the track frame.
