Description

Technical Field

[0001] The utility model relates to the technical field of geological and mineral exploration equipment, in particular to a sampling device for geological and mineral exploration. Background Art

[0002] In the field of geological and mineral exploration, accurate collection of various rock, soil and other samples is a key link in obtaining geological information and evaluating the value of mineral resources. Traditional sampling equipment often faces many challenges during operation. On the one hand, the sampling efficiency is low. With the deepening of exploration work, the requirements for sampling speed and quality are constantly increasing. Existing sampling equipment mostly adopts a single vertical downward movement method, which cannot effectively meet the sampling needs under complex geological conditions. This simple vertical sampling method easily leads to increased friction between the sampling tube and the surrounding medium, which in turn affects the smooth progress of sampling and prolongs the sampling time. On the other hand, the sampling quality is difficult to guarantee. During the sampling process, different geological structures and mineral characteristics have a significant impact on the sampling effect. For example, some rocks have a high hardness, which can easily cause wear and blockage of the sampling tube during sampling, affecting the integrity and accuracy of the sampling.

[0018] See also Figures 1 to 3A sampling device for geological and mineral exploration comprises a mobile base 1 and a sampling mechanism for sampling arranged on the mobile base 1. The mobile base 1 is composed of a bottom plate and a walking wheel arranged at the bottom of the bottom plate, and the middle of the bottom plate is opened so that the sampling mechanism can move up and down. The sampling mechanism is composed of a vertical displacement component 2 arranged on the mobile base 1, a sampling tube sleeve 3 rotatably arranged on the vertical displacement component 2, a sampling tube 7 detachably connected to the sampling tube sleeve 3, and a transmission component 4 arranged on the mobile base 1 and the vertical displacement component 2 and connected to the sampling tube sleeve 3. When sampling, the sampling tube sleeve 3 is driven up and down by the vertical displacement component 2, thereby driving the sampling tube 7 through the vertical displacement component 2. The sampling tube 7 connected to the sampling tube sleeve 3 in a detachable manner such as screws or cylindrical pins moves up and down, and a guide rod 15 is provided on the movable base 1 and vertically slides with the lifting platform 6 to increase stability during movement. The transmission component 4 can drive the sampling tube sleeve 3 to rotate, so it can rotate when the sampling tube 7 moves up and down. The sampling tube 7 is composed of a first semicircular tube 13 and a second semicircular tube 14. A T-shaped slider is provided at the opening of the first semicircular tube 13, and a T-shaped groove adapted to the T-shaped slider is provided at the opening of the second semicircular tube 14. The T-shaped slider slides with the T-shaped groove and the bottom of the sampling tube 7 is toothed to improve the sampling efficiency and sampling quality.

[0019] The vertical displacement assembly 2 for driving the sampling tube sleeve 3 to move up and down is composed of a cylinder 5 arranged on the mobile base 1 and a lifting platform 6 connected to the output shaft of the cylinder 5. The lifting platform 6 is rotated in coordination with the upper end of the sampling tube sleeve 3 so that the sampling tube sleeve 3 is driven to move up and down when the cylinder 5 drives the lifting platform 6 to move up and down. The transmission assembly 4 for driving the sampling tube sleeve 3 to rotate is composed of a rack 8 arranged on one side of the mobile base 1 and a transmission rod 9 arranged horizontally on the lifting platform 6. A transmission assembly 4 is provided at the upper end of the sampling tube sleeve 3 and is connected to the outside of the lifting platform 6. The first bevel gear 10 and the transmission rod 9 are respectively provided with a second bevel gear 11 and a gear 12 at both ends. The first bevel gear 10 is meshed with the second bevel gear 11, and the rack 8 is meshed with the gear 12. When the lifting platform 6 moves up and down, the gear 12 rotates under the action of the rack 8, thereby driving the transmission rod 9 to rotate, thereby driving the second bevel gear 11 connected thereto to rotate, and through the meshing relationship between the first bevel gear 10 and the second bevel gear 11, the sampling tube sleeve 3 connected to the first bevel gear 10 is driven to rotate, thereby driving the sampling tube 7 to rotate.

[0020] After the device is moved to a suitable position, the device can be fixed by setting a braking mechanism, such as a brake pad or a brake, on the running wheel of the mobile base 1; or a retractable support foot or support leg can be set on the mobile base 1; and if the sampling environment permits, a ground anchor connection point can be pre-set on the mobile base 1. When the device is in place, the device is fixed to the ground through the ground anchor.

[0021] Working process and working principle: Move the equipment to the position where sampling is required by moving the base 1, so that the sampling point is located below the opening in the middle of the moving base 1; start the cylinder 5, and the output shaft of the cylinder 5 drives the lifting platform 6 to slide vertically along the guide rod 15. Since the upper end of the sampling tube sleeve 3 is rotated in coordination with the lifting platform 6, the lifting platform 6 drives the sampling tube sleeve 3 to move downward synchronously when it moves downward; and when the lifting platform 6 moves downward, the transmission rod 9 arranged thereon moves downward accordingly, because the gear 12 at one end of the transmission rod 9 is meshed with the rack 8 arranged on one side of the moving base 1, so during the movement of the lifting platform 6, the rack 8 will cause the gear 12 to rotate, thereby driving the transmission rod 9 to rotate, and the second bevel gear 11 at the other end of the transmission rod 9 is meshed with the first bevel gear 10, so when the second bevel gear 11 rotates, it drives the first bevel gear 10 to rotate, thereby making the sampling tube sleeve 3 Rotate, and the sampling tube 7 is connected to the sampling tube sleeve 3 in a detachable manner such as screws or cylindrical pins, and will move up and down and rotate together with the sampling tube sleeve 3, and the bottom of the sampling tube 7 is toothed. During the rotation and downward movement, the toothed bottom helps to cut into the geological sample, improve the sampling efficiency, reduce the friction between the sampling tube 7 and the sample, and can better adapt to geological structures of different hardness, ensuring the integrity and accuracy of the sampling; after the sampling is completed, the cylinder 5 is operated in the reverse direction, so that the lifting platform 6 drives the sampling tube sleeve 3 and the sampling tube 7 to rise back to the initial position, and then the sampling tube 7 is removed from the sampling tube sleeve 3, and the sampling tube 7 is composed of a first semicircular tube 13 and a second semicircular tube 14. The second semicircular tube 14 only needs to slide out from the first semicircular tube 13 to take out the sample, and a sampling work is completed.
