[0042] Working principle of the invention: The use of this structure is mainly divided into three states: normal driving use, filling or water supply, and drill bit disengagement.

[0043] One is normal driving use. During normal driving use, the drill bit body rotates on the bottom side of the drill bit pump body, thus enabling drilling operations. The fixed external drill pipe at the rear end prevents the drill bit body from rotating and causing the drill bit pump body to rotate as well, resulting in slippage. The fixed external drill pipe is equipped with a multi-functional input pipeline and a gas input pipeline. During normal driving, the gas input pipeline can continuously supply gas to the drill bit pump body, causing the drill bit pump body to rotate and drive the drill bit body to rotate. When the gas enters the drill bit pump body, it enters the splitting ring pipe through the connecting gas pipe, and then high-pressure gas is ejected through the pressurized nozzle. The ejected high-pressure gas can drive the turbofan blades, thereby causing the turbofan shaft tube to rotate. The rotation of the turbofan shaft tube drives the reduction mechanism at its bottom end to reduce its high speed, which can be used on the drill bit body, allowing the drill bit body to perform drilling operations at a relatively stable speed.

[0044] Secondly, there is the work of transporting filler and water. In this process, if the water is transported to provide cooling conditions for normal drilling work, and the filler is transported to fill the drill hole and reduce the damage of the drill hole to the geothermal energy, under normal circumstances, if you do not want to input water and filler into the drill bit body, the high pressure generated during the drilling process can be released to reduce the impact on the operation of the drill bit pump. Specifically, water and filler are input through the multi-functional input pipeline and sent directly to the bottom of the drill bit body through the central inner pipe. The through hole in the center of the drill bit body discharges the water and filler through the discharge hole.

[0045] Thirdly, drill bit detachment. In the event of irreparable damage, the drill bit can be detached to protect the drill pump body, thereby reducing damage to the drill pump body. When water flows through the through hole, the high internal pressure of the water allows it to be discharged smoothly through the side discharge hole. However, when mortar or filler is introduced into the through hole, the high pressure of the conveying can affect the self-detachment groove on the side of the through hole, causing the self-detachment groove to be subjected to enormous pressure in the direction of the through hole. The resistance pin in the self-detachment groove will be squeezed, thereby pressing the side close to the spring, causing the end hook connected to the connecting pin to disengage from the connecting pin's engagement range. At this time, because the drill bit body has no fixed object in the engagement direction, under the force of movement and pressure, the drill bit body will detach from the drill pump body. The central inner tube set in the center of the drill pump body can continue to spray filler as the outlet until the drill pump body is retrieved.
