Abstract: The present invention provides a material conveying device including a material conveying groove, having a traveling track; a material bearing and conveying assembly, including: an annular chain; traveling units arranged on the chain at intervals, drivable by the chain to move on the traveling track along a material conveying direction, and provided with a bottom surface close to the material conveying groove, a top surface opposite the bottom surface and side surfaces extending between the top and bottom surfaces; a belt-shaped elastic material bearing portion, connected to the top surfaces and/or the side surfaces of the two adjacent traveling units; and a driving device to drive the chain to circularly rotate relative to the material conveying groove along the material conveying direction. The working state of material conveying equipment can be improved, and the stability and economic index of the equipment can be enhanced.

Abstract: The present invention provides a scraper including a scraper body, having opposed bottom and top surfaces and a supporting body, formed on the bottom surface. The supporting body is provided with a mounting surface forming a part of the bottom surface. The mounting surface is provided with a rolling body able to support the scraping body when the scraper is located at a mounting position. The supporting body is a nonmetallic elastomer. The present invention also provides material conveying equipment using the scraper. By changing a contact and friction mode of the scraper and a conveying groove, a working state of the scraper and the a 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.
