The invention belongs to the technical field of tunneling equipment, and particularly provides a special-shaped tunnel corner excavation device and a tunneling machine. The excavation device comprises a main beam, a movable seat capable of moving front and back is installed on the main beam, installation frames used for installing a rock breaking device are installed on the left side and the right side of the movable seat, and each installation frame is provided with a leveling compensation mechanism used for adjusting the horizontal angle of the corresponding installation frame so as to compensate the offset of the wheel type trailer. The main beam is provided with a hinged connection portion used for being hinged to a wheel type trailer, one end of the leveling driving device is used for being connected with the main beam, the other end of the leveling driving device is used for being connected with a wheel type supporting trailer, or the installation frame is hinged to the movable base, one end of the leveling driving device is used for being connected with the installation frame, and the other end of the leveling driving device is used for being connected with the movable base. The heading machine comprises the excavating device. The rock breaking device can be driven to rotate through the leveling compensation mechanism, it is guaranteed that the rock breaking device is horizontal, and the shape of an excavated section is guaranteed. And meanwhile, the rock breaking device can actively escape.
