[0002] A belt conveyor is a device for transporting materials over long distances and is widely used in all walks of life. The goods carried on the belt conveyor are unevenly distributed when they fall on the belt. This will cause uneven stress on the belt, accelerate belt wear, and place a heavy load on the drive motor. Excessive local accumulation of materials will also cause the materials to fall off the belt. Currently, there is no good way to deal with the uneven distribution of materials in belt transport. Common treatment methods include suspending a scraper above the belt to scrape the passing materials flat. When encountering a thick pile of materials, the materials will fall off the belt from both sides of the scraper, affecting production progress. Therefore, a material spreading device is needed, which is required to spread the passing materials evenly, ensure the uniformity of material distribution on the belt, and reduce belt wear and motor load.
