Description

TECHNICAL FIELD

[0001] The utility model relates to placer exploration device technical field, concretely is a core tube angle adjusting mechanism for placer exploration. BACKGROUND

[0002] As an important mineral resource, the exploration and sampling of placer are crucial for resource assessment and mining. However, the placer usually occurs in extremely complex strata, often distributed in riverbeds, terraces, valley slopes and other non-planar areas. The strata often contain complex components such as pebbles, quicksand layers and fracture zones, which pose great challenges to drilling and sampling work.

[0003] Currently, in the field of placer exploration, the traditional drilling equipment mostly adopts a drilling method with fixed vertical or only a small range of angle adjustment. When the surface of the exploration area has a significant slope or irregular undulation, the rigid structure makes it difficult for the drilling rig to vertically enter the target ore body layer. If forced to operate on an inclined surface, the drill rod will bear additional bending stress, exacerbating wear and tear, and even causing drill rod breakage or sticking accidents. More importantly, the inability to maintain the optimal contact angle between the core tube and the stratum will seriously affect the representativeness and accuracy of the sampling samples, making it impossible to obtain real, undisturbed original cores, ultimately affecting the accurate judgment of ore body grade and reserves.

[0004] Therefore, the drilling rig in the prior art has inherent defects such as poor adaptability, inaccurate sampling, and high equipment wear and tear when dealing with the complex, non-planar exploration terrain commonly found in placer mines. The industry urgently needs a mechanism that can flexibly and accurately adjust the angle of the core tube, allowing the drilling rig to adapt to various rugged work surfaces and ensuring that the core tube can enter the stratum at the most appropriate angle under any terrain conditions, thereby overcoming the technical difficulties of efficient and accurate sampling in complex terrain.

[0005] In view of the above problems, the applicant has conducted in-depth research and thus has developed the present case. SUMMARY

[0006] To overcome the shortcomings of the prior art, the utility model provides a core tube angle adjusting mechanism for placer exploration, which can achieve precise vertical drilling, ensure the authenticity of sampling, and improve the adaptability to complex terrain and work efficiency.
