Description

Technical Field

[0001] This utility model relates to the field of metal ore exploration technology, and in particular to a drilling device for metal ore exploration. Background Technology

[0002] A drilling rig is a complex machine composed of components, units, and mechanisms. It is a mechanical device used in the exploration or development of mineral resources (including solid, liquid, and gaseous minerals) to drive drilling tools underground and obtain physical geological data. Also known as a drilling machine, its main function is to drive the drilling tools to break the rock at the bottom of the hole and lower or lower the drilling tools inside. It can be used to drill cores, ore cores, rock cuttings, gaseous samples, liquid samples, etc., to explore underground geology and mineral resources. Currently, most traditional metal mine exploration drilling devices on the market separate drilling and sampling operations. First, drilling is carried out using drill rods, then casing is installed inside the borehole to protect the borehole wall, and finally, wireline sampling is performed. This drilling method is very inefficient and prone to borehole wall collapse. Therefore, a new type of drilling device is needed that can drill directly and improve the ability to retrieve samples. Utility Model Content

[0003] The main objective of this invention is to provide a drilling device for metal ore exploration, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A drilling device for metal ore exploration includes an exploration vehicle. A base plate is movably mounted on one side of the exploration vehicle. A drilling mechanism is mounted on the upper side of the base plate. The drilling mechanism includes a fixed frame fixedly mounted on the upper side of the base plate. A motor is fixedly mounted on the front side of the fixed frame. A first gear is fixedly mounted on one end of the motor. A second gear is movably mounted on the front side of the first gear. An inner drill barrel is fixedly connected to one end of the second gear. An outer drill barrel is fixedly mounted on the outside of the inner drill barrel. A drill bit is fixedly connected to one end of both the inner and outer drill barrels. An air pump is fixedly mounted on the upper side of the fixed frame. A first air port is fixedly provided on the lower side of the air pump. A cavity is opened on the inner side of the fixed cylinder corresponding to the position of the first air port. Several sets of openings are opened on one side of the outer drill barrel corresponding to the position of the cavity. Several sets of external air pipes are fixedly provided on the other side of the outer drill barrel. A second air port is fixedly provided on one side of the air pump. A connecting pipe is movably connected to one end of the second air port. A sleeve is movably sleeved on the lower side of the connecting pipe. A movable pipe is movably connected to the inner side of the sleeve. Several sets of internal air pipes are fixedly provided on one side of the inner side of the inner drill barrel. A retaining ring is fixedly provided on the side of the inner side of the inner drill barrel near the several sets of internal air pipes.

[0005] Preferably, the fixed cylinder frame is movably connected to the second gear, the first gear and the second gear are meshed, and the second gear is movably connected to the movable tube.

[0006] Preferably, a chamber is fixedly provided between the inner drill barrel and the outer drill barrel, a spiral strip is fixedly provided on the outer side of the outer drill barrel, and the outer drill barrel and the fixed barrel frame are movably connected.

[0007] Preferably, the width of the drill bit is slightly larger than the width of the outer drill barrel, and the several sets of openings are arranged in a circular and uniform manner.

This prevents rock fragments from entering the inner side of the inner drill cylinder during the drilling process, thus enabling normal drilling for metal block exploration. The operation is simple and facilitates subsequent sampling work, resulting in high work efficiency. Secondly, when the drilling depth reaches the required level, the air pump is activated to open the first air port, allowing airflow into the cavity. The high-pressure airflow is then discharged through several sets of external air pipes, pushing the crushed ore into the inner side of the inner drill tube. This achieves integrated drilling and sampling operations, eliminating the need to pull out the drill rod for sampling. This greatly improves the construction efficiency of metal ore exploration, avoids borehole wall collapse, and enhances practicality. Attached Figure Description

A motor 32 is fixedly mounted on the front side of the fixed cylinder frame 31. A first gear 33 is fixedly mounted on one end of the motor 32. A second gear 34 is movably mounted on the front side of the first gear 33. An inner drill barrel 35 is fixedly connected to one end of the second gear 34. An outer drill barrel 36 is fixedly mounted on the outside of the inner drill barrel 35. A drill bit 37 is fixedly connected to one end of the inner drill barrel 35 and the outer drill barrel 36. An air pump 38 is fixedly mounted on the upper side of the fixed cylinder frame 31. A drill bit 37 is fixedly mounted on the lower side of the air pump 38. A first air inlet 39 is provided. A cavity 310 is opened on the inner side of the fixed cylinder frame 31 corresponding to the position of the first air inlet 39. Several sets of openings 311 are opened on one side of the outer drill barrel 36 corresponding to the position of the cavity 310. Several sets of external air pipes 312 are fixedly provided on the other side of the outer drill barrel 36. A second air inlet 313 is fixedly provided on one side of the air pump 38. A connecting pipe 314 is movably connected to one end of the second air inlet 313. A sleeve 315 is movably sleeved on the lower side of the connecting pipe 314. A movable pipe 316 is movably connected to the inner side of the sleeve 315. Several sets of internal air pipes 317 are fixedly provided on one side of the inner side of the inner drill barrel 35. A retaining ring 318 is fixedly provided on the side of the inner side of the inner drill barrel 35 near the several sets of internal air pipes 317.

[0015] In this embodiment, the fixed cylinder frame 31 is movably connected to the second gear 34, the first gear 33 and the second gear 34 are meshed, the second gear 34 is movably connected to the movable tube 316, a chamber is fixedly provided between the inner drill cylinder 35 and the outer drill cylinder 36, a spiral strip is fixedly provided on the outer side of the outer drill cylinder 36, the outer drill cylinder 36 is movably connected to the fixed cylinder frame 31, the width of the drill bit 37 is slightly larger than the width of the outer drill cylinder 36, several sets of openings 311 are evenly arranged in a circle, several sets of external air pipes 312 are evenly arranged in a circle, the sleeve 315 is threadedly connected to the movable tube 316, anti-backflow valves are installed on the inner side of several sets of internal air pipes 317, several sets of internal air pipes 317 are inclined, and one side of the retaining ring 318 is inclined.

[0016] Specifically, firstly, by starting the motor 32 installed on the front side of the fixed cylinder frame 31, the first gear 33 drives the meshing second gear 34 to rotate, thereby driving the connected inner drill cylinder 35 and outer drill cylinder 36 to rotate, causing the drill bit 37 to drill into the exploration site. At this time, by starting the air pump 38 and opening the second air port 313, airflow enters the inner side of the inner drill cylinder 35 through the second air port 313, connecting pipe 314, and movable pipe 316. Simultaneously, the anti-backflow valve inside the inner air pipe 317 prevents the high-pressure airflow from being diverted, thus allowing all airflow to be discharged from the drill bit 37, preventing rock fragments from entering the inner side of the inner drill cylinder 35 during drilling. This enables normal drilling work for metal block exploration, is simple to operate, facilitates subsequent sampling work, and has high work efficiency. Secondly, when the drilling depth reaches the required level, the sleeve 315 is rotated to disconnect the threaded connection between it and the movable pipe 316. At this time, the air pump 38 is started. The first air inlet 39 is opened, allowing airflow into the cavity 310. High-pressure airflow then enters the chamber between the outer drill tube 36 and the inner drill tube 35 through several sets of openings 311. The high-pressure airflow is then discharged through several sets of external air pipes 312. Simultaneously, the motor 32 is started, driving the drill bit 37 to continue rotating and crushing the ore. The high-pressure airflow discharged through the external air pipes 312 pushes the crushed ore to the center of the drill bit 37, and then into the inner side of the inner drill tube 35. At the same time, the airflow in the chamber between the outer drill tube 36 and the inner drill tube 35 also enters several sets of internal air pipes 317, further pushing the ore inside the inner drill tube 35 to a higher position and discharging it through the movable pipe 316 into the sampling box. This achieves integrated drilling and sampling, eliminating the need to pull out the drill rod for sampling, greatly improving the construction efficiency of metal ore exploration. Compared to traditional workflows, it omits some steps, significantly reducing construction time, improving work efficiency, preventing borehole collapse, and enhancing practicality.

[0017] Working principle: In operation, the motor 32 mounted on the front of the fixed cylinder frame 31 is first started, which in turn causes the first gear 33 to drive the meshing second gear 34 to rotate. The second gear 34 then drives the connected inner drill cylinder 35 and outer drill cylinder 36 to rotate, causing the drill bit 37 to drill into the exploration site. At this time, the air pump 38 is started, and the second air port 313 is opened, allowing airflow to enter the inner drill cylinder 35 through the second air port 313, connecting pipe 314, and movable pipe 316. Simultaneously, the anti-backflow valve inside the inner air pipe 317 prevents the high-pressure airflow from being diverted, ensuring all airflow is discharged from the drill bit 37. This prevents rock fragments from entering the inner drill cylinder 35 during drilling, enabling normal drilling for metal block exploration. The operation is simple, facilitating subsequent sampling and resulting in high work efficiency. Secondly, when the required drilling depth is reached, the sleeve 315 is rotated to disconnect the threaded connection between it and the movable pipe 316. At this point, the air pump 38 is started. The first air inlet 39 is opened, allowing airflow into the cavity 310. High-pressure airflow then enters the chamber between the outer drill tube 36 and the inner drill tube 35 through several sets of openings 311. The high-pressure airflow is then discharged through several sets of external air pipes 312. Simultaneously, the motor 32 is started, driving the drill bit 37 to continue rotating and crushing the ore. The high-pressure airflow discharged through the external air pipes 312 pushes the crushed ore to the center of the drill bit 37, and then into the inner side of the inner drill tube 35. At the same time, the airflow in the chamber between the outer drill tube 36 and the inner drill tube 35 also enters several sets of internal air pipes 317, further pushing the ore inside the inner drill tube 35 to a higher position and discharging it through the movable pipe 316 into the sampling box. This achieves integrated drilling and sampling, eliminating the need to pull out the drill rod for sampling, greatly improving the construction efficiency of metal ore exploration. Compared to traditional workflows, it omits some steps, significantly reducing construction time, improving work efficiency, preventing borehole collapse, and enhancing practicality.
