The specific implementation process is as follows:

after the stones are crushed and ground into stone powder in the crushing and grinding machine, the stone powder falls onto the conveyer belt 16 through the funnel 3, when the stone powder just falls onto the conveyer belt 16, a large amount of flying dust is generated and scattered in the air, and at the moment, the flying dust can be well prevented from scattering into the air under the blocking of the dust cover 201 and the dust pipe 202. When the stone powder falls on the conveyer belt 16, the conveyer belt 16 is in an arc shape with two downward sides and upward sides in the middle of the downward stroke under the gravity action of the stone powder and the supporting action of the roller set 4, so that the stone powder is always conveyed in the middle of the conveyer belt 16, and the stone powder is prevented from falling out of the conveyer belt 16 from the edge of the conveyer belt 16; and meanwhile, the edges of two sides of the conveyer belt 16 below the dust cover 201 are abutted against the rubber sheets 5, the rubber sheets 5 are soft, the conveyer belt 16 can be prevented from being scratched or damaged in the transmission process of the conveyer belt 16, the rubber sheets 5 give downward pressure to the edges of two sides of the conveyer belt 16, and the conveyer belt 16 can be prevented from being overwound under the gravity action of stone powder to a certain extent. After the stone dust is conveyed out of the dust cover 201, the rollers 8 can still apply downward pressure to the edges of the two sides of the conveyer belt 16, thereby preventing the two sides of the conveyer belt 16 from being overwound. When the conveyer belt 16 is driven, the roller set 4 will rotate along with the conveyer belt 16, so as to reduce the friction between the roller set and the conveyer belt 16 and prolong the service life of the conveyer belt 16. The stone dust is transported on the conveyor belt 16 via the transverse frame 101 to the diagonal frame 102 and then to a storage silo or other storage container. When the stone powder is transported, the conveyer belt 16 moves back from the bottoms of the transverse frame 101 and the inclined frame 102, so as to realize circulation. During the back-conveying of the conveyer belt 16, the supporting rollers 9 at the bottom of the transverse frame 101 and the oblique frame 102 can support the conveyer belt 16 to prevent the conveyer belt 16 from excessively dropping downward.
