[0002] In sintering production, sintering material distribution directly affects the output and quality of sinter. The process requires that the sintering material distribution must be uniform and flat. The situation of material distribution has a great influence on the flatness and air permeability of the surface.

[0003] In the prior art, a round roller leveling device or a scraper leveling device is used to level the sintering surface: raw materials fall from the bin to the feeding system, and after passing through the feeding system, they cover the sintering machine trolley and are leveled by the round roller leveling device or the scraper leveling device. In the actual production process, due to the large self-weight of the round roller leveling device, the leveled material layer is too compact, resulting in poor air permeability of the material layer, and it is difficult to scrape flat the deeper grooves on the surface, and the flatness of the surface is poor, seriously affecting the quality of sinter; while the scraper leveling device is in line contact with the surface, it is difficult to form a relatively flat surface, and it is easy to cause grooves on the leveled surface due to local wear or bonded material of the scraper.
