ROD ROTARY DRIVING DEVICE AND GROUND IMPROVEMENT MACHINE
PROBLEM TO BE SOLVED: To provide a rod rotary driving device which can chuck a rod at any position and can be reduced in size, and a ground improvement machine using the same.SOLUTION: A rod rotary driving device 5 comprises: a body 17 having a drive shaft 20 engaged with a rod 6 rotatably; a rod chuck mechanism 18 which is provided rotatably in the drive shaft; and a chuck release mechanism 19. The rod chuck mechanism comprises: a plurality of wedge members 25 which are movable only in a rod radial direction; a hollow cylindrical slide member 26 which is brought into contact with an inclination surface 25a of the wedge member; and a spring member 27 which energizes the slide member in a rod shaft direction. By pressing a reception plate 31 provided in an outer periphery of the slide member by a cylinder 34 provided in the body, the slide member is made to slide against the energization force of the spring member, the wedge members are moved to the outside in the rod radial direction by the spring 28 to release chuck.
【課題】ロッドの任意の位置でチャックでき、小型化が可能なロッド回転駆動装置及び該ロッド回転駆動装置を適用した地盤改良機を提供する。【解決手段】ロッド回転駆動装置５は、ロッド６を係合する駆動シャフト２０を回転可能に備えた本体１７と、駆動シャフトに回転可能に設けられたロッドチャック機構１８と、チャック解除機構１９とを備え、ロッドチャック機構は、ロッド半径方向にのみ移動可能な複数のクサビ部材２５と、クサビ部材の傾斜面２５ａと接触する中空円筒状のスライド部材２６と、スライド部材をロッド軸方向に付勢するバネ部材２７とを備え、本体に設けられたシリンダ３４によってスライド部材の外周に設けられた受けプレート３１を押すことにより、バネ部材の付勢力に対抗してスライド部材をスライドさせ、クサビ部材がバネ２８によりロッド半径方向外側に移動しチャックを解除する。【選択図】図２
