Pouring and vibrating equipment for large-volume concrete of skewback

The utility model relates to the technical field of building construction equipment, in particular to pouring and vibrating equipment for large-volume concrete of an arch support, which comprises a mounting box internally provided with a vibrating pump, fans are arranged on the two sides of the vibrating pump in the mounting box, air guide ports are formed in the side walls, corresponding to the fans, of the mounting box, and the equipment further comprises a dustproof mechanism. The dustproof mechanism comprises a dustproof ring belt with meshes, a belt body of the dustproof ring belt is tensioned and transmitted by transmission shafts which are arranged on the four horizontal side edges of the mounting box in a parallel and rotating mode, and the belt body of the dustproof ring belt is used for shielding the air guide opening. According to the cooling device, the dynamic dustproof ring belt is adopted, so that the problem that a traditional fixed filter screen is easily blocked by sundries can be prevented,
