A roadway opening heading machine comprises a rack and a heading device; a walking mechanism is arranged below the rack; the heading device is hinged onto the rack provided with a console for controlling the machine; the heading device comprises a crushing hopper, a connecting rod mechanism and a small arm hinged to a large arm; the large arm is hinged to the rack; the small arm is connected with the large arm and is hinged to the crushing hopper; the crushing hopper is hinged to a piston end of a hydraulic cylinder by the connecting rod mechanism and one end in a cylinder body end; the other end is fixed on the large arm; the console is electrically connected with the hydraulic cylinder by an electrical control box. Compared with the prior art, the heading machine has the beneficial effects that the vibrating heading device replaces a large-sized rotating disk, and precious operation time is saved. The size of a working mechanism is smaller, so a load is smaller and energy is saved.
