ABSTRACT:
In a rotary table driven hollow auger type sampling device, a rod is mounted at an end above the rotary table to be substantially fixed against rotation, but for axial movement. The rod extends through a hollow spindle driven by the table, and is fixedly mounted below the table to the upper end of a thin wall sampling tube mounted within a hollow auger to project a short distance below the lower end of the auger. The rod, hence the sampling tube, is forced downwardly with the auger, but is positively restrained from rotation.
