PROBLEM TO BE SOLVED: To overcome the problems of a risk of mixing-in of an impurity and of abrading a screw blade and a casing itself by a carrying object when abrasion is caused by rotation of the screw blade since the carrying object is carried when pushed in while being stirred between the screw blade and the casing, of requiring labor for manufacture and incorporation due to being formed as an integrated screw structure, and of being limited in capacity for carrying the carrying object and being limited in the size of the carrying object comparatively in the size of the casing, in a conventional carrying machine.SOLUTION: This invention can also carry powder of a high abrasion characteristic, without substantially causing mixing-in of the impurity, without making a screw compete with the casing, since the screw blade simultaneously rotates with the casing. A screw blade unit is also formed by dividing the screw blade, and is formed as a structure for continuously and easily installing these blades. A capacitively large allowance is further arranged by eliminating a shaft attached with the screw blade. |
