The width of the tunnel which can be excavated by the tunneling machine is determined by the swing amplitude of the cutting part at the front end of the tunneling machine, if the tunneling is wanted to be performed, the tunneling machine is moved for a plurality of times along the transverse direction of the tunnel (namely the width direction of the tunnel) in the tunneling process, and the tunneling efficiency of the tunneling is seriously reduced because the moving mechanism of the tunneling machine is a crawler belt, so that the tunneling machine is not changed in the transverse direction.

If a driving structure capable of driving the cutting part to move along the length direction and the transverse direction of the roadway is added on the heading machine, the problems that the cutting width is limited and the heading distance is limited after the existing heading machine is fixed are solved.
Meanwhile, after the cutting width of the heading machine is increased, if the width of the scraping tray below the heading machine is unchanged, the cut coal cannot fall into the scraping tray when the cutting part moves to the leftmost side or the rightmost side, and high-efficiency transportation of the cut coal mine is not facilitated.
