[0006] The rotating mechanism includes a driving system, a bevel gear transmission assembly and a rotating disc, the motor output shaft of the driving system is connected to the bevel gear transmission assembly in a gearbox, the gearbox is fixed on the upper surface of the outer end of the telescopic cantilever, the bevel gear transmission assembly is connected to a rotating shaft, the rotating shaft is fixed to the center of a base provided on the upper surface of the gearbox, the base is provided with a rotating disc, and the excavator device is fixed to the rotating disc.

[0007] The excavator device is a four-bar linkage structure.

[0008] The utility model discloses a beneficial effect is: the rotary mechanism has been arranged behind the excavator device, can change the angle of excavator device, facilitate all -round excavation cleaning smooth groove bottom plate, through the telescopic pad frame of adjusting can rotate the base and excavator device on it and push forward or pull back, guarantee excavator can send the coal in scraper conveyor, also can adapt to different mining range requirement. High flexibility, effectively solved the back of the return airway conveyor, need along the top and dig the bottom, coal, gangue is easy to accumulate, difficult to clean, artificial cleaning efficiency is low and other problems.
