The present invention relates to a drive shaft installed in a sludge collector and rotating by a rotary power delivered from a driving power source, in which an output shaft (120) of a drive motor (110) comprises a sprocket housing (10) mounted on a drive power delivery line of the drive motor (110) and having a pin hole (12) and an inclined groove (14) formed on the body; a sleeve housing (20) combined to the sprocket housing (10) and having a front end pin hole (22) corresponding to the pin hole (12) formed on the body; a front end pin (30) inserted into the front end pin hole (22) and the pin hole (12); and a detector (40) combined to the sleeve housing (20) and projected from the inclined groove (14) in the process of breaking the front end pin (30) to contact with a detection sensor (50). A chain stopping tool rotates at the same rotary speed to a driven shaft, so that the instant management is possible in malfunction of components including a driven chain, and, therefore, the working efficiency of the sludgy collector is maximized. |
