The invention discloses a double-wire segmented spiral auger device. The problems that when an existing spiral auger conducts rolling and cutting processing on forage grass and other materials, the rolling and cutting time is long, and efficiency is low are solved. The auger is provided with an auger pipe. Two sets of spiral blades distributed around the double helix are welded to the auger pipe.Each spiral blade is provided with three holes provided with two star-like blades and a circular blade correspondingly. The auger is horizontally arranged in a material box, one end of the auger is connected with an auger through shaft, the auger through shaft is connected with a coupler, the coupler is connected with a motor, and accordingly power provided by the motor is obtained. According to the solution, the motor is powered on and rotates, the coupler is used for transmitting power to the auger through shaft, and under driving of the auger through shaft, the auger pipe, the spiral blades, the circular blades and the star-like blades jointly rotate. After forage grass is added in the material box through a feeding port, under rotation of the auger, the spiral blades compress and convey the forage grass, meanwhile, the circular blades conduct non-support cutting, shearing faces are formed by the star-like blades and fixed cutters arranged on the material box wall, multi-cross rolling and cutting are conducted on the forage grass, and the forage grass processing efficiency is effectively improved.
