When in specific use:

figures 6-8 show one embodiment of the present invention mounted on a tractor. When the tractor operates, the control system firstly acquires the running speed and the running state of the tractor, and controls the main driving motor of the cable drum according to the running speed and the running state of the tractor, wherein the control strategy is as follows: the number of winding turns of the main drive motor's encoder real-time monitoring reel body, thereby judge the number of piles at the real-time place of cable, the diameter of cable winding is calculated through the level at cable place, through reel body diameter, the tractor real-time speed and the required rotational speed of system's transmission speed reduction ratio calculation main drive motor, thereby the speed closed loop control is carried out to the encoder real-time monitoring speed through main drive motor simultaneously, thereby carry out PID regulation to main drive motor's speed through the tension of angle sensor detection cable.

Therefore, through the accurate control of the cable arranging device, the cables are always orderly and orderly arranged on the winding drum body, and the reliable winding of the long-distance cables can be ensured.

In the process of winding and unwinding the drum body, the winding direction of the cable on the path (vehicle running path) of the ground and the winding direction of the cable on the drum body form 90 degrees, the first cable guide frame under the telescopic arm adopts a space splayed roller structure, the cable space can be effectively guaranteed to be kept smooth under the 90-degree winding path, and the cable can smoothly transition from the left semi-spoke to the right semi-spoke of the first cable guide frame under the condition that the tractor turns around.
