Description

Technical Field

[0001] The utility model belongs to the technical field of scraper machines, and more specifically, particularly relates to a replacement structure for a chain plate of a scraper machine. Background Art

[0002] A scraper conveyor is a continuous transport device that uses a moving chain to convey bulk materials in a closed rectangular cross-section housing. It is widely used in industries and sectors such as coal, mining, grain and oil, food, and feed. Existing scrapers generally consist of a support frame, a drive mechanism, a chain, and a chain plate.

[0003] Based on the above, the chain plate of the scraper conveyor is in direct contact with the material in daily use and is greatly worn, so it often needs to be replaced. However, the chain plates of scraper conveyors used in coal, mining and other industries are mostly heavy, and usually require two people to cooperate when replacing them. One person picks up the chain plate, and the other person directs to continuously adjust the position of the chain plate. Only after the threaded holes of the chain plate and the threaded holes of the chain connecting plate are aligned can they be fixed with fastening bolts, which is more troublesome to operate.
