ROD ROTARY DRIVING DEVICE AND SOIL IMPROVEMENT MACHINE
PROBLEM TO BE SOLVED: To provide a rod rotary driving device capable of surely holding a rod which projects upward from a rod rotary driving device body and suppressing shake of an upper part of the rod, with a simple structure.SOLUTION: A rod rotary driving device 5 comprises a body 13 having a drive shaft in a rotatable manner which a rod 6 is inserted into and is engaged with, rod chuck means 14 which is installed under the body 13 and which can integrally rotate with the drive shaft, and rod-shake stopping means 15 which is installed in the upper part of the body 13 and which can integrally rotate with the drive shaft. The rod-shake stopping means 15 comprises a cylindrical member 21 which is provided upward from the top face of the drive shaft, a ring-shaped upper cover member 22 fastened to the top edge of the cylindrical member, and a plurality of roller members 23 arranged in the upper cover member 22 in the circumferential direction and at equal intervals and abutting the outside face of the rod 6, and the roller member 23 can rotate via a support shaft of the horizontal direction.SELECTED DRAWING: Figure 3
【課題】 シンプルな構造で、ロッド回転駆動装置本体から上方に突出したロッドを確実に保持し、ロッド上部の振れを抑制できるロッド回転駆動装置を提供する。【解決手段】 ロッド６を挿通係合する駆動シャフトを回転可能に備えた本体１３と、本体１３の下部に設けられ、駆動シャフトと一体回転可能なロッドチャック手段１４と、本体１３の上部に設けられ、駆動シャフトと一体回転可能なロッド振止手段１５とを備えたロッド回転駆動装置５であって、ロッド振止手段１５は、駆動シャフトの上面から上方に向って設けられた筒状部材２１と、筒状部材の上端に固着されたリング状の上部カバー部材２２と、上部カバー部材２２に周方向に等間隔で配置され、ロッド６の外面に当接する複数のローラ部材２３とを備え、ローラ部材２３は、水平方向の支軸を介して回転可能である。【選択図】 図３
