Abstract
PURPOSE: To improve the transportation ability by alternately disposing parallel screw shafts, one makes turning motion only and the other makes axial movement as well as turning, so as to give a least chance that mud will be deposited on the screws.
CONSTITUTION: Screw shafts 4a, 4b which are parallelly disposed and have screw threads 5a, 5b on the same direction so as to turn uni-directionally are arranged in such a manner that those threads 5a, 5b are mutually raised into their pitches. The shaft 4a is held as to make turning motion only and the shaft 4b is disposed as to make a little axial motion so that if mud is deposited on the screw threads during transportation, the screw threads scrapes it with each other. Thereby, creation of such an occasion may be prevented that the transportation may be impossible because the mud is deposited throughout the screw threads.
