Chain type scraping disk, manufacturing method thereof and conveying device using chain type scraping disk

The invention discloses a chain type scraping disk, a manufacturing method thereof and a conveying device using the chain type scraping disk. A chain is used as a connecting piece of feeding scrapingdisks, wherein the chain is formed by stringing closed rings one by one, can bear large pulling force and is not easy to break; meanwhile, steel rods are vertically welded on the chain; the feeding scraping disks are integrally molded and wrap the steel rods in a injection molding manner; two rods of the chain simultaneously penetrate through the feeding scraping disks; each feeding scraping diskhas two penetrating contact ring surfaces so as to increase a contact area and be not easy to slip off; the steel rods perpendicular to a movement direction of the chain are further arranged while thefeeding scraping disks are not easy to slip off; the steel rods are welded on the chain; the feeding scraping disks wrap the steel rods to further increase a connecting force between the feeding scraping disks and the chain, s
