Description

Technical Field

[0001] The present application relates to the technical field of geological prospecting equipment, and more specifically, to a drill rod for geological prospecting. Background Art

[0002] Efficient and accurate geological exploration is of great significance to resource development, geological disaster prevention, etc. In the process of geological exploration, in order to obtain geological information and samples deep underground, relevant staff often use geological exploration drill rods.

[0003] The document with prior art publication number CN219101239U provides a drill rod device for geological exploration. By setting moving wheels, the device does not need multiple workers to carry the equipment together to the next exploration point, and the operation is not troublesome. It will not affect the efficiency of exploration, nor the convenience of workers.

[0004] Although the above-mentioned existing technical solutions improve the convenience of transporting drill rods, they still have the following defects: when the drill rod is drilling downward for a long time, the drill bit will inevitably generate heat, which will not only damage the drill bit and shorten the service life of the drill bit, but also be detrimental to the smooth progress of exploration. In view of this, we propose a drill rod for geological exploration. Utility Model Content
