The utility model discloses an automatic calibration system for detecting the rotation angle of a bucket wheel machine. The device is characterized by comprising a bucket wheel machine slewing mechanism, a slewing encoder used for detecting the slewing angle of the bucket wheel machine slewing mechanism, a first slewing calibration device used for left-side-45 calibration and a second slewing calibration device used for middle-0 calibration. The third rotation calibration device is used for right side + 45 calibration; the PLC control system is used for calibrating a rotation angle value to a current position calibration value; the bucket wheel machine rotation mechanism takes a bucket wheel machine rotation center point as a circle center and performs leftward or rightward rotation action under the control of the PLC control system; the rotation encoder is connected with a rotation driving gear of a rotation center of the bucket wheel machine, a signal output end of the rotation encoder is connected with the
