Abstract

PURPOSE: To change a screw diameter just by blade pipe exchange, to reduce cost and to facilitate repairing by freely fittably and detachably attaching a blade pipe to which a screw blade is fixed to the outer periphery of an auger shaft provided with female and male joints on end parts. CONSTITUTION: To the outer periphery of the auger shaft 1 composed of a steel pipe for which the male joint 2 and the female joint 3 are attached to upper and lower end parts by welding, the blade pipe 4 composed of the steel pipe for which the screw blades 5 of the various kinds of diameters are fixed to the outer periphery is freely fittably and detachably fixed through the male and female joints 2 and 3 and bolts 6. Then, when changing the screw diameter or repairing a damaged blade, only by performing exchange with a new blade pipe 4 provided with the screw blade 5 of a desired diameter, the change of the diameter or repairing is easily performed and manufacture cost is substantially reduced.
