Hydraulic pulse drill bit

The utility model relates to a hydraulic pulse drill bit which is composed of a drill bit body, a cutting member, a water eye, a righting shaft sleeve, a rotor, a stator, etc. The utility model is characterized in that the righting shaft sleeve is matched with the rotor; a suspended rotary shaft is sheathed in the righting shaft sleeve; the lower end of the suspended rotary shaft is connected with the rotor; the suspended rotary shaft, the righting shaft sleeve, the stator and the rotor form a component which is arranged in an inner cavity of the drill bit body, and the stator and the drill bit body are fixed. Drilling fluid passes through the stator to adjust impact direction, and pushes the rotor to do forced rotation. A flow passage at the lower end of the rotor and the water eye of the drill bit are superposed sometime, and are staggered sometime. Thus, the flow quantity of the drilling fluid entering the water eye is adjusted. As a position where hydraulic pulse is generated is close to a bottom hole, the pulsation of high amplitude value and peak value can be generated at the flow field of the bottom hole. Thus, the rock breaking drilling efficiency is raised. The utility model has the characteristics of simple structure, convenient use and operation, safety, low pressure consumption, strong adaptability, etc. The utility model has important practical meaning for raising the penetration rate of deep and ultradeep well drilling.
