MULTI-AXIS TYPE DRILLING AND STIRRING APPARATUS AND MULTI-AXIS TYPE DRILLING AND STIRRING METHOD

摘要

To solve the problem in which the conventional multi-axis drilling and stirring apparatus adopts a configuration in which each drilling shaft is engaged with gears and the like to synchronously rotate a plurality of drilling shafts, and the configuration is complicated and the weight is increased.SOLUTION: A multi-axis type drilling and stirring apparatus is configured such that a plurality of drilling shafts 8 are provided to hang from an auger 4 in parallel with each other, a drilling head 10 provided with a plurality of stirring blades 9 in the rotational direction is provided at a lower part of each drilling shaft 8, the stirring blades 9 of each drilling shaft 8 provided in parallel are arranged so that they are out of phase with the stirring blades 9 of each adjacent drilling shaft 8 in plan view and do not hit each other during rotation, thereby the rotational trajectories of the stirring blades 9 of each adjacent drilling shaft 8 are arranged so as to partially overlap in plan view, a rotation synchronous control of a control unit 16 which makes an individual motor 15 which drives each drilling shaft 8 feed back and calculate the rotation information of a rotating shaft 18 of each individual motor 15 is executed, and the stirring blades 9 of each drilling shaft 8 rotate synchronously while maintaining the arrangement state in which the phases are different.SELECTED DRAWING: Figure 7
