Anti-dust device for underground turn-back type ore dumping chamber and ore dumping locomotive

The invention discloses an anti-dust device for an underground turn-back type ore dumping chamber and an ore dumping locomotive. The anti-dust device comprises a dust cover box body, a rotating shaft,a guide wheel assembly, a guide rail and a cover plate hook, wherein the dust cover box body is provided with a dust cover; the dust cover box body is movably arranged on an ore dumping station; a first position enabling the dust cover to cover a mine mouth and a second position enabling the dust cover to open the mine mouth are arranged on a movable path of the dust cover box body; the guide wheel assembly is arranged at the end of the rotating shaft; the guide rail is in a step shape; and the guide wheel assembly can walk along the guide rail to drive the rotating shaft to rotate. Through the matching action of the anti-dust device and the ore dumping locomotive, an ore dumping port of the ore dumping locomotive can be kept in a closed state all the time in a non-ore dumping time, so that dust can be effectivel
