AI Technical Summary
Existing drilling equipment for mine geological exploration is prone to deviating from the vertical trajectory during drilling, resulting in core sample fracture, disordered bedding, severe frictional loss, and drill bit jamming, which affects operational efficiency and sample integrity.
The system employs a combination of a lifting ring and an impact rod. Through the axial movement of the lifting ring and the high-frequency vibration of the impact rod, vibration feeding is achieved across the entire length of the drill barrel. An automatic material receiving structure driven by an electric cylinder, combined with the stable support of the ground-inserting rod, ensures vertical drilling of the drill barrel and prevents deviation.
It ensured the integrity of core samples and the accuracy of exploration data, improved the automation level and efficiency of the material preparation process, reduced the intensity of manual operation, simplified the device structure, and improved operational stability.
