The invention discloses a self-cooling industry mechanical
drill bit. The self-cooling industry mechanical
drill bit comprises a hollow
drill body. An
electrification structure is arranged on the outer surface of the hollow drill body. The
electrification structure is jointly composed of an annular fixing groove, a second connecting wire and a heat exchange device located in the hollow drill body,wherein the annular fixing groove is located in the annular side surface of the upper end of the hollow drill body and fixedly connected with the hollow drill body, the second connecting wire is located on the side surface of a negative
electrode chip, one end of the second connecting wire is fixedly connected with the negative
electrode chip, the middle of the second connecting wire is connectedwith a second circular through hole in an inserted manner, and the other end of the second connecting wire stretches into the hollow drill body. The heat exchange device is jointly composed of a horizontal partition plate, rotation blades and a
cutting structure, wherein the horizontal partition plate is located on the inner surface of the hollow drill body and is fixedly connected with the hollow drill body in the horizontal direction, the rotation blades are located at the rotation end of a rotation motor and are fixedly connected with the rotation motor, and the
cutting structure is located at the lower end of the hollow drill body. The rotation motor is electrically connected with a first connecting wire and the second connecting wire, and a
refrigeration compressor is electrically connected with the first connecting wire and the second connecting wire. The self-cooling industry mechanical
drill bit has the beneficial effects that the structure is simple, and practicability is high.
