The utility model has a simple structure. After the water inlet pipe is connected to a water pump, water is introduced into the hollow connecting shaft through the water inlet pipe, and then the drill bit connecting flange flows into the sleeve gap between the inner drill bit and the outer drill bit through the first water tank, and finally flows out from the through hole of the drill bit and the sleeve gap between the drill bit and the inner drill bit and the outer drill bit. When drilling, not only is there no need for additional personnel to hold a water pipe to inject water into the drill hole separately, but also the occurrence of the situation that the drill bit cannot be injected with water after drilling into the rock formation, the drill bit temperature increases, the efficiency is reduced, and the drill bit is easily damaged is greatly reduced. The core drilling is more efficient, the inner drill bit and the outer drill bit are simple to design and produce, there is no need to set up a complicated waterway, and the device is more convenient to use.

[0004] When the existing coring machine is in use, due to the contact between the coring machine and the concrete surface layer, the contact surface is uneven, which will cause displacement when extracting the core sample, resulting in deviation in the diameter of the extracted core sample. In addition, when extracting deeper concrete core samples, the extracted core sample may be stuck inside the drill bit, making it impossible to remove the core sample, resulting in poor practicality.
