Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Fig. 1 to 3 show a preferred embodiment of a coal conveying device according to the present invention. As shown in the figure, the coal conveying device comprises a conveying belt and a conveying belt support 1 suitable for supporting the conveying belt, the coal conveying device further comprises a spiral conveyer 9 erected above the conveying belt, the spiral conveyer 9 comprises a cylindrical spiral conveying shell 91, a main shaft and a plurality of spiral blades mounted on the main shaft are arranged in the spiral conveying shell 91, a plurality of mounting holes are formed in the spiral conveying shell 91, a screen 92 is mounted in each mounting hole, and the size of a screen hole of the screen 92 is set to allow coal blocks smaller than a preset size to fall onto the conveying belt from the spiral conveying shell 91. The coal conveying device provided by the present disclosure screens and separates coal blocks (such as coal dust) smaller than a predetermined size through the screen 92 on the spiral conveying shell 91 in the coal conveying process, and falls onto the conveying belt below, and conveys the coal blocks through the conveying belt below, while larger coal blocks are left in the spiral conveying shell 91 to be conveyed through the spiral conveyor 9, so that the sorting function is realized in the conveying process.

As shown in fig. 1 to 2, in an exemplary embodiment, the coal conveyor further includes a dust cover provided above the conveyor belt, the dust cover and the conveyor belt enclosing a space in which the screw conveyor 9 is provided.

As shown in fig. 1 to 2, in an exemplary embodiment, the dust cover includes a plurality of support frames 2 connected to the wear-resistant canvas 3 and adapted to support the wear-resistant canvas 3, the plurality of support frames 2 are spaced apart along a length direction of the conveyor belt, rollers 5 are respectively disposed at both ends of the support frames 2, the rollers 5 are slidably connected to rail grooves 4 disposed at both sides of the conveyor belt support 1, and a plurality of magnetic structures 6 are disposed at intervals along a lower edge of the wear-resistant canvas 3 along an extending direction of the conveyor belt to be magnetically connected to the conveyor belt support 1.
