(54) MATERIAL CONVEYING DEVICE AND SCRAPER


(57) The present invention provides a scraper. The scraper includes: a scraper body, having a bottom surface and a top surface opposite to the bottom surface; and a supporting body, formed on the bottom surface of the scraper body, wherein the supporting body is provided with a mounting surface and the mounting surface forms a part of the bottom surface; the mounting surface is provided with a rolling body, and the rolling body is able to support the scraping body when the scraper is located at a mounting position; and the supporting body is a nonmetallic elastomer. Meanwhile, the present invention provides material conveying equipment using the scraper, for example a scraper conveyor. By changing a contact and friction mode of the scraper and a conveying groove, the working state of the scraper and the whole load of the conveyor are improved, idle load is reduced, and the whole service life of the scraper and even the scraper conveyor is prolonged.
