Rotary jetting anchor cable construction drill bit
The invention discloses a rotary jetting anchor cable construction drill bit, comprising a drill rod, an anchor cable fixed on the drill rod, one end of the drill rod is provided with a drill bit, a bearing is fixedly sleeved on the drill rod, an anchor cable fixing plate is fixed on the bearing in a matching manner, the anchor cable is fixed on the anchor cable fixing plate, and a drill rod joint is fixedly sleeved at the other end of the drill rod. By means of the structures of the bearing and the anchor cable fixing plate, when the drill rod drills a hole, the anchor cable fixing plate is guaranteed not to rotate along with the drill rod, mutual twining and stirring between the anchor cables are avoided, simultaneously, the drill rod can not bring the anchor cables out of finished holes, the drill bit and the anchor cables reach the designed hole depth simultaneously, prefabricated hole operation is not needed, and the operation steps are simplified. The drill bit has a relatively lower manufacturing cost, is convenient to use, and has very good practicability and market application value.
