The invention relates to a tunnel boring machine, in particular to a coal stripping device for a coal mine rock road shoulder angle applied to a TBM boring machine. It is safe and reliable, and can assist TBM equipment to cut and excavate coal at the shoulder and corner of coal mines. A shoulder angle coal peeling device and a blanking collector are installed on both sides of the main girder X. The two shoulder angle coal peeling devices are the left shoulder angle coal peeling device and the right shoulder angle coal peeling device; The horizontal moving track is fixed on the main beam X, a horizontal moving seat is slidably connected to the horizontal moving track, and the horizontal moving seat is connected with the translation oil cylinder; The moving seat is connected with the internal slideway through a telescopic oil cylinder and a telescopic pin shaft; the left side of the large cutting drum is connected with the small cutting drum by a bearing; the right side of the large cutting drum is supported on the internal slideway by a bearing. |
