This utility model relates to the field of dust and waste conveying technology, and in particular to a closed conveying device for dust and waste from roadheaders and anchorers. It includes a conveying frame, a conveying component, and multiple idlers. The conveying frame has two first conveying rollers symmetrically and rotatably connected to its inner wall. The conveying component includes a
conveyor belt tensioned and sleeved on the two first conveying rollers. The working surface of the
conveyor belt has a V-shaped conveying groove along its width. Multiple idlers are arranged at intervals along the conveying direction within the conveying frame and are rotatably connected to the inner wall of the conveying frame. In this utility model, the V-shaped conveying groove on the working surface of the
conveyor belt effectively constrains the waste, preventing it from dispersing during conveying, reducing the exposed area of the waste, and lowering the possibility of dust generation. The idlers provide linear support to the conveyor belt, ensuring stable operation and preventing waste from scattering due to belt swaying, thus improving the stability and reliability of the conveying process.
