Abstract
Disclosed is a novel autonomous excavating apparatus capable of solving conventional problems. The autonomous excavating apparatus comprises an apparatus body including a lower body 101 formed in a cylindrical shape and combined with a conical-shaped lower end, and a spiral blade 102 provided on an outer peripheral surface of the lower body 101 in the form of a right-handed screw. The lower body 101 has an internal space provided with a wheel 103 which has a rotary shaft 104 rotatably supported relative to the lower body 101 through bearings 105, 106. A motor 108 is fixed to the lower body 101 at a position above the wheel 103, and an output shaft of the motor is coaxially connected to the rotary shaft 104. Thus, the motor 108 can drivingly rotate the wheel 103 relative to the lower body 101.
