The invention discloses a scraper feeding system. The scraper feeding system comprises a base plate, a chain, a plurality of main scrapers, auxiliary scrapers, a protection plate and connecting links, wherein the chain is longitudinally arranged on the base plate; the protection plate covers the chain; the main scrapers are transversely arranged on the base plate at intervals; both ends of the main scrapers are connected with the chain through the connecting links respectively, and synchronously move along with the main scrapers; the end parts of each main scraper are fixedly connected with the auxiliary scrapers; the auxiliary scrapers are clung onto the protection plate. Since the auxiliary scrapers are arranged and can synchronously move along with the main scrapers and the chain, when a mixed material is conveyed, the main scrapers continuously scrape the mixed material on the base plate for moving backwards, and the auxiliary scrapers also continuously scrape the mixed material on the protection plate for conveying backwards; therefore, the conveying efficiency of the mixed material is improved, the accumulated materials on the protection plate can be timely cleared up, and the difficulty of the follow-up cleaning operation is greatly reduced. The invention further discloses a spreading machine adopting the scraper feeding system.
Description
technical field [0001] The invention relates to the field of road construction machinery, in particular to a scraper conveying system and a paver. Background technique [0002] The main function of the paver scraper conveying system is to convey the mixture in the paver hopper to the rear of the machine body. The existing scraper conveying system generally adopts chain transmission. The chains are arranged on both sides of the bottom plate. The chains on each side are arranged along the longitudinal direction of the bottom plate. Scrapers are installed on the side of the chain in the vertical direction (horizontal direction of the bottom plate). The chain drives the scraper. The plate moves on the surface of the bottom plate; in order to prevent the mixture from entering the chain and causing stagnation, an inclined protective plate is installed above the chain, and the inclined setting of the protective plate can minimize the residue of the mixed material. However, due to ...
