Zusammenfassung:	A wind controller comprises a wind cylinder, two ends of which respectively work as a wind inlet and a first wind outlet. A second wind outlet is formed in a cylinder wall of the wind cylinder; and the edge of the second wind outlet is movably connected with a wind door shielding the first wind outlet or the second wind outlet. Concentration of head-on dust of a work surface of a heading machine can be reduced, so clear visual sense of the work surface of the heading machine can be achieved; and therefore, work efficiency of the heading machine can be improved.
