Conveying belt blowing device

The utility model relates to the technical field of conveyer belt maintenance, in particular to a conveyer belt blowing device, which comprises a mounting frame, a conveyer belt arranged at the upper part of the mounting frame, and a blowing pipe arranged below the output end of the conveyer belt and parallel to the width direction of the conveyer belt. The dust blowing device is reasonable and compact in structure, when the dust blowing device is used, the front end of the blowing pipe is connected with a compressed air station through an air pipe, then compressed air is continuously supplied, transverse spraying is formed at the nozzle, dust attached to the surface of the conveying belt is impacted and blown when materials fall, the dust is in a raised state, and the dust is prevented from falling off. The material dust amount is reduced, the difficulty and risk of cleaning the scattered dust below the conveying belt are reduced, the field environment is improved, meanwhile, the material utilization effect
