MULTI-AXIS TYPE DRILLING AND STIRRING APPARATUS AND MULTI-AXIS TYPE DRILLING AND STIRRING METHOD
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
【課題】従来の多軸掘削撹拌装置では、各掘削軸を歯車等を噛み合わせて、複数の掘削軸を同期回転させる構成を採用しており、構成が複雑で重量が嵩むという課題がある。【解決手段】オーガー４から複数の掘削軸８を互に平行状態で垂下するように設け、各掘削軸８の下部には撹拌翼９を回転方向に複数設けた掘削ヘッド１０を設け、平行状態に設けた各掘削軸８の撹拌翼９は、隣接する各掘削軸８の撹拌翼９と平面視それぞれ位相を相違させて回転中に互いに当たらないように配置することにより、隣接する各掘削軸８の撹拌翼９の回転軌跡を、平面視において一部重なるように配置し、各掘削軸８の撹拌翼９は、各掘削軸８を駆動させる個別電動機１５を、各個別電動機１５の回転軸１８の回転情報をフィードバックさせて演算する制御部１６の回転同期制御を実行して、位相を相違させた配置状態を維持して同期回転する構成とした多軸式掘削撹拌装置。【選択図】図７
