Problems solved by technology
When geological exploration is carried out in the prior art, due to the large exploration depth, it is necessary to connect multiple connecting cylinders and drill cylinders for drilling. However, most of them require manual installation or disassembly, which has a large workload and low work efficiency. The soil inside the entire drill pipe will be taken out, and the backfilling operation is cumbersome

The invention discloses a geological drilling device convenient to assemble, disassemble and sample for construction. The geological drilling device comprises a machine body, a working cavity is formed in the machine body, a drill hole is formed in the bottom wall body of the machine body, a base used for supporting is fixedly installed at the bottom end of the machine body, a connecting base is fixedly installed on the inner wall of the left side of the working cavity, a connecting groove is formed in the connecting base, and a connecting cylinder mounting and dismounting assembly used for mounting and dismounting a connecting cylinder and a drilling cylinder is arranged in the working cavity. When the device works, the connecting cylinder and the drilling cylinder can be mounted or dismounted through the connecting cylinder mounting and dismounting assembly, drilling can be conducted through the drilling cylinder drilling assembly, bottom soil can be sampled through the sampling assembly, the workload of workers is reduced, and the exploration efficiency is improved.
Description
Technical field[0001]The invention relates to the related field of geological prospecting equipment, in particular to a geological drilling device for construction which is convenient for installation and disassembly and sampling.Background technique[0002]"Geological exploration" refers to the investigation and exploration of geology through various means and methods to determine the appropriate bearing layer, determine the foundation type and calculate the basic parameters according to the bearing capacity of the foundation. When performing geological exploration in the prior art, due to the large exploration depth, multiple connecting barrels are required to be connected to the drill barrel for drilling. However, most of them require manual installation or disassembly. The workload is large and the work efficiency is low. All the soil in the entire drill tube will be taken out, and the backfilling operation is complicated.Summary of the invention[0003]In view of the shortcomings o...
