The rear end of the mounting baffle plate is provided with a spray hole and a nozzle is arranged, and the spray hole is communicated with the central hole of the main rod through the flow channel through the radial hole of the main rod.
The utility model relates to a horizontal directional traversing drilling tool, in particular to a horizontal directional traversing drill bit with a reverse nozzle, which comprises a main rod and a central hole of the main rod, a fixed mounting baffle plate and an installation plate on the main rod, and a mounting baffle plate and an installation plate are fixedly connected on the main rod. A drill bit is installed in the circumferential direction of the installation plate, and the drilling tool is characterized in that a spray hole is opened at the rear end of the installation baffle plate and a nozzle is installed, and the spray hole is connected with the central hole of the main rod through the flow channel through the radial hole of the main rod. When the utility model works, the pressure mud enters the injection hole from the central hole of the main rod through the radial hole of the main rod and the flow channel of the drill bit, and is sprayed from the nozzle to the cuttings passing through the rear of the drill bit, so that the cuttings can be discharged smoothly, and the cuttings can pass through when dragging back. The drill is not blocked by cuttings. The beneficial effects of the utility model are as follows: 1. The cuttings at the rear of the drill bit can be discharged smoothly and in time, so as to avoid the cuttings from hindering the dragging of the crossing drill bit; 2. The wear of the crossing drill bit is reduced, and the service life of the crossing drill bit is prolonged; Reasonable.
