Description

Technical Field

[0001] The present invention mainly relates to the technical field of geological prospecting drilling, and in particular to a geological prospecting drilling system. Background Art

[0002] Geological exploration drilling is an engineering technology used to obtain geological information such as underground rocks, soil, water, etc. This technology is widely used in geological surveys, mineral resource exploration, hydrogeological exploration, environmental geological surveys, and foundation surveys for engineering construction.

[0003] A drilling device for geological exploration in frozen areas described in the prior art starts an electric telescopic rod in a storage frame, and allows the output rod of the electric telescopic rod to squeeze a rubber water tank. After the rubber water tank is squeezed, the water flow inside will be sprayed out through the connecting pipe, thereby soaking the frozen soil surface, thereby softening and lubricating the frozen soil. Since the frozen soil is soaked in water, the soil will soften, and the drill bit of the drilling rig will also be lubricated by water during operation, so that the drilling rig can break the frozen soil more quickly and efficiently, greatly improving the working efficiency of the drilling rig, thereby achieving the purpose of allowing the drilling rig to drill into the frozen soil quickly. At the same time, by installing a guard plate, the slide plate plays the role of shielding the soil. When the drilling rig drills the soil out of the ground, it will be thrown out by the drilling rig. At this time, the guard plate can prevent the soil from being thrown out, and the soil is controlled between the two sets of guard plates, which is also convenient for subsequent collection and sampling of the thrown soil.

[0004] Although the above technology can control the soil generated by drilling through guard plates and slide plates to prevent it from being thrown out, the soil generated will gather at the borehole under the continuous drilling of the drill bit, and the accumulation of soil will increase the rotational resistance of the drill rod, consume more power, and cause increased wear.
