PURPOSE:To enable a coil and a rotary shaft to be easily connected with and disconnected from each other by screwing the coil into a screw part formed along the rotary shaft surface in a device where powder, etc., are transported by turning the coil inserted into a cylindrical body. CONSTITUTION:The upper end of a coil 2 inserted into a tube 1 is connected with the rotary shaft 4 of a motor 3, and powder, etc., taken in from an intake port 5 are carried upward and discharged from a shoot 6 by turning the coil 2 by means of the motor 3. In this case, the coil 2 and the rotary shaft 4 are coupled with each other via a connecting tool 10. Namely, the rotary shaft 4 is fixed in a mounting hole 8 provided on one end of the connecting tool 10 via a setscrew, etc., and the coil 2 is similarly screwed into a screw part 9 provided on the other end of the connecting tool. Hereby, it is possible to easily connect the coil 2 to the rotary shaft 4 in an concentric state as well as facilitate the replacement of the coil 2. |
