The invention provides drilling equipment suitable for frozen soil geology, which comprises a central control
machine, two handles, an air injection
assembly, a linkage sleeve, a sampling mechanism and a
drill bit. The two handles are arranged on the two sides of the central control
machine respectively, and the linkage sleeve is in linkage connection with the central control
machine. According to the drilling equipment suitable for the frozen soil geology, the central control machine, the two handles, the air injection
assembly, the storage
assembly, the sampling mechanism and the
drill bit which are arranged are matched with one another. The sampling device has the function of detaching the sampling device from the
drill bit device, and after sampling is completed, the storage assembly is detached and replaced, so that a sample can be rapidly detached and stored, and new sampling work cannot be delayed. By means of the design, the sampling device can effectively solve the problem that when a sampling device in the prior art samples frozen soil, due to the freezing swelling phenomenon, personnel are difficult to take out a soil sample from the sampling drill
barrel, and the working efficiency of personnel in frozen soil sampling is greatly improved.
