Detailed Embodiments

[0019] The following further describes the present utility model with reference to the accompanying drawings.

[0020] Embodiment 1: Please refer to Figures 1-5 , the present utility model provides a technical solution: a sampling device for geological and mineral exploration, including a driving member 1 and a drill barrel 2. The driving member 1 uses an electric motor. The working end of the driving member 1 is fixedly connected with a transmission member 4 through a coupling 3. On the surface of the drill barrel 2 and near one end of the driving member 1, there is a transmission groove 5 connected to the transmission member 4. There are multiple transmission grooves 5 and they are evenly distributed along the circumferential direction of the drill barrel 2. The drill barrel 2 is in transmission connection with the transmission member 4 through the transmission groove 5. Inside the drill barrel 2, there is a sampling barrel 6;

[0021] The sampling barrel 6 includes a first half barrel 61 and a second half barrel 62. One side of the first half barrel 61 and the second half barrel 62 is fixedly connected with a hinge 63. The first half barrel 61 and the second half barrel 62 are combined into a cylindrical structure under the connection of the hinge 63. The other side of the first half barrel 61 and the second half barrel 62 is provided with a fixing fastener 64. The sampling barrel 6 is composed of two half barrels, which is convenient for taking out the ore inside. At the same time, one side is hinged through the hinge 63, which is convenient for the combination of the two half barrels and improves the combination efficiency. The fixing fastener 64 fixes the two half barrels together, preventing the half barrels from rotating around the hinge 63.

[0022] During the drilling process, the driving member 1 drives the drill barrel 2 to rotate, enabling the drill barrel to enter the geological layer. At the same time, the ore enters the inside of the sampling barrel 6, realizing drilling and sampling. After drilling, by directly taking out the sampling barrel 6, it is avoided to take out the ore inside, thus avoiding the mixing of ores at different depths.

[0023] On the surface of the drill barrel 2 and near one side of the transmission groove 5, there is a fixed ring 8 fixedly connected. On the top of the fixed ring 8, there is a rotating ring 9. The bottom of the rotating ring 9 is fixedly connected with a ring seat 91. On the surface of the fixed ring 8, there is a sliding groove adapted to the ring seat 91. Inside the sliding groove, there is a limiting groove to limit the rotation angle of the ring seat 91, so that the rotatable angle of the ring seat 91 is 6 - 10°. Between the bottom of the ring seat 91 and the fixed ring 8, there is a torsion spring 81. Through the setting of the torsion spring 81, the ring seat 91 can be quickly reset after rotation. The transmission member 4 includes a fixed disk 41. At the bottom of the fixed disk 41, there is a transmission rod 42 adapted to the transmission groove 5. Inside the inner wall of the rotating ring 9, there is a through groove 92. The width of the through groove 92 is greater than the width of the transmission rod 42, ensuring that the rotating ring 9 can rotate. On one side of the transmission rod 42, there is a clamping groove 43 adapted to the through groove 92. By clamping one side of the through groove 92 into the clamping groove 43, it is avoided that the transmission member 4 moves along the length direction of the drill barrel 2, thus ensuring the stability during the drilling process.

[0024] After the transmission member 4 is connected to the transmission groove 5, the top of the sampling barrel 6 contacts the bottom of the fixed disk 41, avoiding the shaking of the sampling barrel 6.

[0025] To further improve the stability of the sampling cylinder 6, a thread 65 is provided on the surface of the sampling cylinder 6 near one side of the bottom end, and the sampling cylinder 6 is threadedly connected to the drilling cylinder 2.

[0026] The bottom end of the drilling cylinder 2 is provided with a feed port 21, and a drill tooth 7 is also fixedly connected to the bottom end of the drilling cylinder 2, which facilitates breaking the geological layer through the drill tooth 7.

[0027] The surface of the drilling cylinder 2 is provided with spiral teeth 10 to facilitate the screwing-in of the drilling cylinder. A handle 11 is fixedly connected to the surface of the driving member 1 for convenient operation.

[0028] When installing the sampling cylinder 6, insert the sampling cylinder 6 into the drilling cylinder 2 and tighten it in place. Align the transmission rod 42 of the transmission member 4 with the transmission groove 5, and rotate the rotating ring 9 to ensure that the transmission rod 42 is installed in place. Then loosen the rotating ring 9. Under the action of the torsion spring 81, the rotating ring 9 resets, and one side of the through groove 92 is caught in the card slot 43; take out the sampling cylinder 6 according to the reverse steps; when opening the sampling cylinder 6, place the sampling cylinder 6 on the table, open the fixing fastener 64, and turn over the top half cylinder to expose the extracted ore.
