PURPOSE:To shorten and lighten a screw and to facilitate the insertion, opening, and transport of the screw by engaging the extractable driving shaft of the screw with the tip of an output shaft provided at a driving part. CONSTITUTION:A material to be conveyed such as sludge is charged into a conveying part 33 from an opening 30 provided at the upper part, and the plural screws 31 arranged inside are rotated to send the material continuously to a discharge port 32. The detachable driving part 34 is connected to the driving side of the screw 31 adjacently to the conveying part 33, and the screws 31 are simultaneously rotated. One ends of the screws 31 are freely rotatably supported on the driven side of the conveying part 33 through a bearing 37, and the other ends are engaged with the tips 39a of the plural output shafts 39 protruding into the conveying part 33 from the driving part 34 and made freely extractable. As a result, the wear of the screw shaft is prevented, and the screw is easily taken out and handled. |
