    • An auger of the present invention has four-stage speeds, and the auger comprises: an auger driving unit which has a frame capable of being attached to an excavator or a crane, and supplies rotary power for excavation; and a lower drilling device unit which is attached to the lower part of said auger driving unit, and directly performs drilling work on the ground. Said auger driving unit comprises: two motors which supply rotary power with electricity; speed reduction device units which are combined with the lower part of each said motor, and reduce the rotating speed; a rotation device unit which receives the rotary power transmitted from said speed reduction device units, and transmits the rotary power to said lower drilling unit in connection with said lower drilling unit such as a screw or a bottom bit or the like for performing the drilling work; and an auger base frame on which said motors, the speed reduction units, and the rotation unit are installed, and which is capable of being attached to said excavator or the crane, wherein: pole change motors capable of converting poles into 4 poles and 6 poles or 4 poles and 8 poles are used as said motors; said speed reduction units comprise a first speed reduction unit for reducing the number of rotations, a second speed reduction until which reduces the number of rotations that had been reduced from the first speed reduction unit again, a third speed reduction unit which reduces number of rotations that had been reduced from the second speed reduction unit again, said first, second, and third speed reduction units are reduced in speed in a planetary-geared shift gear that comprises a ring gear, a planetary gear installed on a planetary gear carrier, and a linear gear; and a speed reduction opening/closing device is formed between said first speed reduction unit and the second speed reduction unit, wherein the speed reduction opening/closing device enables the linear gear of said first speed reduction unit to be in contact with an internal gear of the planetary gear carrier such that the linear gear is primarily reduced in speed, or enables the linear gear to be separated from the contact to prevent the linear gear from being primarily reduced in speed. According to the present invention, the invention enables: the work to be carried out with four speeds by generating the rated torque without losing power transmission of the motors, so that electric loss and torque can be lowered when the speed is reduced by using an inverter, thereby avoiding an increase of drilling costs by preventing the eventual increase of equipment costs due to large motors and the mechanical speed reduction parts which increase in size according to the large motors; large-hole drilling or small-hole drilling work can be performed by the same piece of equipment; and four types of speed changes are available according to the condition of the ground, whereby labor costs and equipment costs are reduced by an improvement of work efficiency.
