摘要： There is provided an extrusion auger having auger segments that are removable from an auger shaft and that include a recess to facilitate removal of the auger segments. A pulling tool is also provided to engage the recess of the auger segment and to facilitate the removal of auger segment from the auger shaft in an axially forward direction. The auger segment includes an access way to provide access to the recess and the recess includes an engaging surface. The pulling tool includes a flanged end that can pass through the access way of the auger segment and contact the engaging surface of the auger segment. The recess of the auger segment may be located in a bore of the auger hub such that the pulling tool can be advanced along a keyway in the auger shaft, rotated to pass the flanged end of the pulling tool through the access way, and pulled axially forward to contact the engaging surface.
摘要翻译：提供了一种挤压螺旋推运器，其具有可从螺旋钻轴上移除的螺旋钻段，并且包括凹槽以便于去除螺旋推运器段。还提供了拉动工具以接合螺旋推运器段的凹部并且便于在轴向向前的方向上从螺旋推运器轴上移除螺旋推运器段。螺旋推运器段包括提供通向凹部的通路，并且凹部包括接合表面。拉动工具包括可以穿过螺旋推运器段的通路的凸缘端，并与螺旋钻段的接合表面接触。螺旋推进器段的凹部可以位于螺旋钻毂的孔中，使得牵引工具可以沿着螺旋钻轴中的键槽前进，旋转以使牵引工具的凸缘端通过通路，并且轴向拉动向前接触接合表面。
