The mining fully-mechanized excavating machine automatic cable retracting method by using the retracting system claimed in any one of claims 1 to 7, characterized in that the rope arranging cam rotates clockwise, the rope arranging slide block is positioned at the leftmost end of the rope arranging slide rail when the cam roller passes through the stroke of the near repose angle, and the cable wheel winds the rope for one circle; when the rope passes through the pushing stroke, the rope arranging slide block translates to the rightmost end along the rope arranging slide rail, in the process, the cable wheel continuously rotates for winding, and the cable is wound to the rightmost end from the leftmost end; when the rope passes through the stroke of the far angle of repose, the rope is wound for one circle at the rightmost end position; when the rope passes through the four-section stroke of the return stroke, the rope arranging slide block returns to the leftmost end from the rightmost end of the rope arranging slide rail, in the process, the cable wheel continuously rotates for winding, and the cable is wound to the leftmost end from the rightmost end; the process is repeated in this way, and the purpose of uniform rope arrangement is achieved.
10. The automatic cable retracting method of the mining fully-mechanized roadheader as claimed in claim 9, wherein the radius of the cable sheave is increased continuously during the cable retracting process, and in order to ensure the uniform distribution of the cable on the cable sheave, the rotation speed of the cable sheave is controlled by the thickness of the rope winding and the traction speed of the roadheader together.
