It is widely used in the mining of underground gas, liquid minerals such as oil and natural gas.

[0003] In the process of oil extraction, an oil extraction drill pipe assembly is needed. The oil drilling rig in the existing technology is mainly composed of eight parts, including a power machine, a transmission machine, a working machine and auxiliary equipment. For example, a drilling drill pipe and a drilling drill pipe. When using an oil drilling rig to crush and drill the target well using the oil extraction drill pipe, it is necessary to sample different positions. The operator has to move the drill pipe to drill and sample multiple times, which will increase the workload of the operator and reduce the sampling efficiency. In addition, the impurities remaining on the surface of the oil extraction drill pipe need to be cleaned according to the needs of the construction. However, most of the existing oil extraction drill pipes adopt manual flushing. This cleaning method not only wastes water resources, but also has low cleaning efficiency and cannot meet the use requirements.

Hydraulic cylinders 62 are fixedly mounted within each mounting block 61, and scrapers 63 are fixedly connected to the output ends of each hydraulic cylinder 62. The controller 3 activates the extension and retraction of the two hydraulic cylinders 62, respectively, to move the scrapers 63 closer or further apart. Simultaneously, the lifting mechanism 7 and the cleaning mechanism 6 work in concert to facilitate scraping and cleaning of impurities from the outer surface of the drill rod 42, thereby resolving the resource waste and incomplete cleaning issues associated with conventional water-based cleaning, achieving the advantages of ease of use and effective cleaning.

[0026] The two hydraulic cylinders 62 are both electrically connected to the controller 3 in a synchronous manner, and the outer diameter of the drill rod 42 is adapted to the curvature of the two scrapers 63 .

[0027] Specifically, the drill rod structure 4 includes a speed regulating motor 41 disposed outside the installation box 2 . The output shaft of the speed regulating motor 41 is fixedly connected to a drill rod 42 . The drill rod 42 is located between the two scrapers 63 .
