The utility model discloses a tunneling machine which comprises a cutting head (1) and a transportation device (3). The transportation device (3) comprises a front end part and a rear end part hinged with the front end part through a first articulated axle (41); the axis of the first articulated axle (41) is positioned in the horizontal plane and perpendicular to the convey direction of the transportation device (3); and the rear end part rotates relatively to the front end part along the first articulated axle (41) under the action of a first power component. Therefore, when raw coal on the transportation device needs to be conveyed to a convey vehicle, the first power component drives the rear end part to rotate along the first articulated axle to realize up-and-down motion of the rear end of the transportation device; and the height difference between the rear end of the transportation device and the convey vehicle is adjusted, and the raw coal is conveyed when the height difference therebetween is smaller
