Reproducing method for scraper conveyor

The invention discloses a reproducing method for a scraper conveyor, and belongs to the technical field of machine manufacturing. Fault detection is carried out on a welding gap by detecting the wear and failure quantity of components of the scraper conveyor, and judging is carried out according to the wear and failure quantity of the components and whether the welding joint is defected or not. According to the method that repairing and/or replacing are/is carried out to achieve reproducing, the reproducing of the scraper conveyor is achieved in a real sense. The repairing and/or replacing can be carried out on important structures, such as a middle plate, a bottom plate, the two sides of a scraper plate and a chain way and two side plates of a machine head frame, of a scraper, so that the reproducing method for the scraper conveyor has the advantages that the cost is saved, the material and resource wastes are lowered, and the service life of the device is prolonged.
