Preferably, it is provided with the cylinder to rotate between the end of side board, the end fixing of cylinder is provided with first carousel, the transfer roller tip of conveyer belt head end rotates respectively and is provided with the second carousel, the periphery of first, second carousel is provided with a plurality of claws that push along circumference, through a plurality of claws that push of first, second carousel promote in proper order connect the fixed axle of hopper.

Preferably, a belt is tensioned on the roller, and the surface of the belt is tightly attached to the upper opening of the receiving hopper.

Preferably, a first through hole is formed in the side wall of the head end of the side plate, a feeding channel is fixedly arranged on the first through hole, and a discharge hole of the feeding channel faces the upper portion of the head end of the conveyor belt.

Preferably, a second through hole is formed in the side wall of the tail end of the side wall plate, a discharge channel is fixedly arranged on the second through hole, and a feed inlet of the discharge channel faces the lower portion of the tail end of the conveyor belt.

Preferably, a discharge hopper is arranged below the position between the conveyor belt and the roller and is communicated with the discharge channel.

Preferably, the surface of the conveyor belt has a grid texture.

The embodiment of the invention has the following beneficial effects:

the invention adopts the plurality of receiving hoppers and moves along with the conveyor belt, and can receive the coal dust generated in the coal feeding and discharging processes of the raw coal, thereby preventing the coal dust from being exposed to the outside, effectively improving the dust suppression range, greatly improving the working environment and realizing the closed conveying of the raw coal.
