Abstract
The invention provides an arch-shaped tunnel excavating machine. A large drill bit II and two small drill bits I cut soil behind the drill bits (I and II) while rotating, so as to obtain approximately arch-shaped holes comprising one large circular hole and two small circular holes, which are lapped with one another; cutters on three transmission rods cut soil on three edges of the approximately arch-shaped holes while rotating; the cut soil is transported to a transportation device, and transported out of tunnels by the transportation device. The arch-shaped tunnel excavating machine can excavate arch-shaped tunnels in a propelling process.
