The feed hopper is vertically installed at one end of the machine body along the conveying direction. The top of the feed hopper is open and the bottom is narrowed. A protective plate is installed inside the feed hopper and is fixedly installed on the inner wall of the feed hopper. Multiple protective plates are installed, and all of them are inclined. The bottom of the protective plate is fixed to the inner wall of the feed hopper, and the top of the protective plate is inclined upward away from the inner wall of the feed hopper. This prior art has the characteristic of reducing damage to the inner wall of the feed hopper and has the effect of ensuring the normal use of the belt conveyor.

[0004] However, a problem exists when using belt conveyors to transport coastal placer deposits: due to the adhesive properties of coastal placer sand, sand and gravel mixed in the ore easily adhere to the belt surface during transportation.
