CONSTITUTION:A rotating cylinder 1 in which a flange 8 is formed is rotatably inserted into upper and lower fixed cylinders 2 and 6, and a fixed pipe 7 is inserted thereinto from am upper end port 2' of the fixed cylinder 2 and a fixed cover 3 into thereinto from an lower end port 6' of the fixed cylinder 6, respectively, and they are tightly attached thereto. The flange 8 is rotated by a motor, and the screw 4 tightly installed in the ritating cylinder 1 is rotated together with this rotating cylinder 1. A lower part of the screw 4 is to be a shovel with claws 5 which is exposed to the outside from a notch part of the cover 3, scraping up earth and sand.
