PROBLEM TO BE SOLVED: To prevent run-off of drilling earth without deformation of a screw and ensure reliable earth removal.SOLUTION: The present invention provides an auger that comprises: a revolving shaft 13; a spiral screw 14 which is mounted around the shaft 13; a post 31 with top and bottom ends fixed to the peripheral ends of blades that are spaced apart each other in the axial direction O of the shaft 13 of the screw 14; an opening/closing shaft 32 which is supported by the post 31 and shaft 13; and an opening/closing lid 33 that is available to close a space between adjacent blades which are separated each other in the axial direction O of the screw 14 and that is supported so as to be able to open and close by the shaft 32.SELECTED DRAWING: Figure 3
【課題】スクリューを変形させることなく掘削土の流出を防止することができ、確実な排土を行うことができる。【解決手段】回転軸１３と、回転軸１３の周りに螺旋状に設けられたスクリュー１４と、スクリュー１４の回転軸１３の軸方向Ｏに離間する羽根の外周端のそれぞれに上下端が固定されたポスト３１と、ポスト３１と回転軸１３とに支持された開閉軸３２と、スクリュー１４の軸方向Ｏに離間する羽根同士の間を閉塞可能とするとともに、開閉軸３２によって開閉可能に支持された開閉蓋３３と、を備えた構成のオーガーを提供する。【選択図】図３
