Manual barring gear for agitator

The utility model provides a manual rotor turning gear used for an agitator, which is arranged on an agitator. The utility model comprises a large angle gear and a small angle gear, which are matched with each other. The large angle gear is arranged inside a motor frame of the agitator, and is connected to an input shaft of a retarder of the agitator. An axis of rotation passes across the side wall of the motor frame, and is matched with the motor frame in a moving way. The outer end of the axis of rotation is connected with a rocking handle. The small angle gear is connected to the inner end of the axis of rotation to form the moving joggled structure of the large angle gear and small angle gear. Before the utility model is started up, low-speed large torque is input manually; a manual jigger is used so that an agitator blade loosens and agitates the media firstly, and then a motor is started up to drive the agitator to work. The starting success rate is ensured. The utility model is effective, has simple and reliable structure, and is usable.
