Rotating shaft mechanism for mounting crawler belt and crushing and regenerating machine

The invention discloses a rotating shaft mechanism for mounting a crawler belt and a crushing and regenerating machine, and belongs to the technical field of engineering machinery. The rotating shaft mechanism comprises a plurality of supporting rods, and the supporting rods are connected with a mounting seat; the rotating shaft is arranged on the mounting seat through a buckle; clamping parts are arranged on the two sides of the buckle, and a pit matched with the rotating shaft body is formed in the middle of the buckle; a first through hole is formed in the clamping part, a bolt penetrates through the buckle and then is connected with a nut, and the bolt and the nut clamp the two ends of the rotating shaft into the concave part; a limiting assembly is arranged on the bolt; the limiting assembly is arranged between the clamping parts on the two sides of the buckle. A second groove matched with the limiting assembly is formed in the rotating shaft; according to the invention, the rotating shaft is more conven
