Abstract
The present invention relates to a hydraulic drill bit capable of remotely controlling drilling, slotting and correcting deflection, which belong to the mining and drilling field. The deflection correcting drill bit of the prior art has a big structure, can not adapt the construction requirement that a pipe is continuously propelled, and can not carry out the switching of a drilling and slotting process; thus, the application range is limited. The drill bit provided by the present invention is composed of a spray head capable of rotating at an angle, a slotting nozzle, a drilling, a switching mechanism for slotting, and a driving mechanism capable of rotating at an angle. Because a rotary shell is additionally arranged on the structure, a rotary sleeve is arranged on the rotary shell so as to enable the rotary shell and the drill bit to rotate at an angle together, and consequently, the deflection correcting function can be realized. Because the present invention reasonably provided with a water filling channel and a second hydraulic channel, the drilling and slotting process can be conveniently switched, and the construction requirement can be satisfied. The present invention has the advantages of compact structure, simple in the switching operation of the drilling and the slotting, and reliable and exact deflection correcting. The present invention can be widely applied to the construction operation that the steel pipe is continuously propelled to be drilled and slotted by high-pressure water jet.
