Abstract

A drill bit used for a geological tent comprises a support rod. The drill bit is arranged below the support rod. A center hole is formed in the support rod and the drill bit. A push rod is arranged inside the center hole. Two bore spines are arranged at the lower end of the push rod. Bore spine outlets are formed in the drill bit. The drill bit is inserted to the ground, the push rod is pushed downwards, and the bore spines extend out along the bore spine outlets and penetrate into the stratum. The drill bit used for the geological tent has the advantages of being simple in structure and good in stability.

Description

technical field [0001] The invention relates to a drilling bit for a geological tent. Background technique [0002] At present, the drill bit of the known geological tent pole is a tapered drill bit. When in use, it is easy to fall off, unstable, and cannot guarantee the firmness of the tent. It is time-consuming and laborious, which brings a lot of inconvenience to people. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a drilling bit based on a geological tent, which has the characteristics of simple structure and good stability. [0004] In order to realize the above-mentioned deficiencies in the prior art, the technical solution adopted in the present invention is: a kind of drilling bit based on the geological tent, including a support rod, a drilling head is provided under the support rod, and a middle hole is arranged in the support rod and the drilling head ...
