SOIL DISCHARGING ADAPTER, DRILLING DEVICE AND SOIL DISCHARGING COLLECTION SYSTEM
PROBLEM TO BE SOLVED: To prevent degradation of a work environment and a surrounding environment by recovering drilling muck without scattering it in air.SOLUTION: A soil discharging adapter of the present invention is characterized by including: a cylindrical adapter body fixed in a drifter while surrounding a rod of the drifter; and a cylindrical cover having a discharging part for discharging the scattered drilling dust by air sent during drilling in an outer circumferential surface, and capable of moving between a first position with the other end of a steel pipe fitted while the adapter body is fitted and a second position where the fitting of the other end of the steel pipe is released.SELECTED DRAWING: Figure 2
【課題】削孔ズリを大気中に飛散させることなく回収することで、作業環境や周囲環境の悪化を防止する。【解決手段】本発明の排土用アダプタは、ドリフタのロッドを包囲した状態で前記ドリフタに固定される筒形状のアダプタ本体と、削孔時に送り込まれる空気により飛散する削孔塵を排出させる排出部を外周面に有する筒形状であり、前記アダプタ本体が嵌入された状態で、鋼管の他端部が嵌入される第１位置と前記鋼管の他端部の嵌入が解除される第２位置との間で移動可能なカバーと、を備えたことを特徴とする。【選択図】 図２
