The sampling tower of belt conveyor is generally arranged in the flat section of belt conveyor. The scraper sampler is installed on the sampling guide trough, and a rotating scraper head is arranged inside. During sampling, the sampling head automatically samples the material on the conveyor belt at fixed time intervals. The material transported on the conveyor is taken from the stockpile by the bucket wheel of the cantilever reclaimer. The stockpile is inhomogeneous and unstable, and it is easy to collapse when taking materials, resulting in an increase in the amount of material taken. In this case, the material on the conveyor belt will be too high, forming a higher arc-shaped bulge, which will scratch the scraper head when entering the sampling guide trough, causing the scraper sampler to malfunction; if the sampling head is sampling at this time, the excessively high material cannot be scraped into the bucket by the sampling head, affecting the sampling quality, and at the same time, the leakage of the material pushed to the outside of the guide trough may touch the protection switch, causing the conveyor belt to stop; all of the above situations will affect the operation of the conveyor belt and reduce operating efficiency, so a material leveling device that can automatically level the excessively high material is needed.
