PURPOSE: A four shaft auger device for stirring soft ground is provided to improve quality of ground after excavation and stirring by individually differentiating rotation directions and rotation speed of an excavation stirring rod with four shafts according to a working condition. CONSTITUTION: A four shaft auger device for stirring soft ground comprises an auger gear shaft assembly (26) of four groups and a rod gap control unit (32). The auger gear shaft assembly is formed by installing a gear box (25) on the periphery of an auger driving gear shaft and an auger driven gear shaft. The auger driven gear shaft is connected to a screw rod of four shafts and an excavation stirring rod. The auger driving gear shaft is combined with a driving motor and is connected to one side of the auger driven gear shaft. The rod gap control unit controls the gap between each auger gear shaft assembly by individually moving the auger gear shaft assembly of the four groups forwards and rearwards and right and left. |
