挤压螺旋传送器和挤压螺旋传送器装置
摘要：
本发明提供了一种具有螺旋传送器段的挤压螺旋传送器，该螺旋传送器段可从螺旋传送器轴上拆卸，且该螺旋传送器段包括凹口，以便于拆卸该螺旋传送器段。还提供了一种拉动工具，以便与螺旋传送器段的凹口接合，并便于将螺旋传送器段沿轴向向前方向从螺旋传送器轴上拆卸。螺旋传送器段包括进入通道，以便能够进入凹口，且该凹口包括接合表面。拉动工具包括凸缘形端，该凸缘形端能够通过螺旋传送器段的进入通道，并与螺旋传送器段的接合表面接触。螺旋传送器段的凹口可以位于螺旋传送器轮毂的孔中，这样，拉动工具可以沿螺旋传送器轴中的键槽前进，并旋转以便使拉动工具的凸缘形端通过进入通道，并沿轴向向前拉动，以便与接合表面接触。
摘要（英）：

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 theauger 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.
