[0034] Embodiment 1:

[0036] The rotating assembly includes a turntable 8 with a circular ring structure installed on the top of the base 1, two sliders 25 symmetrically fixedly connected to the inner side of the turntable 8, a gear ring 23 fixedly connected to the outer side of the turntable 8, a rack 22 installed on one side of the gear ring 23, a motor 11 fixedly connected to the top of the base 1, a rotating rod 21 fixedly connected to the output shaft of the motor 11, a connecting rod 10 rotatably connected to the end of the rotating rod 21, two limit plates 24 arranged on the outer ring of the turntable 8 and a guide plate 9 fixedly connected to the top of the base 1 and arranged near the rack 22, one end of the connecting rod 10 away from the rotating rod 21 is rotatably connected to the rack 22, the slide groove 16 is slidably connected with the slider 25, the two limit plates 24 are fixedly connected through a plurality of fixed seats 7, and the bottoms of the plurality of fixed seats 7 are fixedly connected to the base 1, the outer ring of the turntable 8 is symmetrically fixedly connected to the two extension plates 26, the extension plates 26 are slidably connected to the corresponding limit plates 24, and the rack 22 is slidably connected to the guide plate 9.

[0037] The slide groove 16 on the outside of the drilling rod is matched and plugged with the slider 25 of the turntable 8. When the drilling rod goes deeper, the motor 11 runs, and the motor 11 drives the rotating rod 21 to rotate. The rotating rotating rod 21 can realize the rotation of the connecting rod 10 and then the displacement operation. The moving connecting rod 10 can better drive the rack 22 to move horizontally. When the rack 22 moves, the rotation operation of the turntable 8 can be realized through the gear ring 23. When the rotating rod 21 rotates continuously, the connecting rod 10 reciprocates left and right, thereby realizing the reciprocating movement operation of the rack 22, so that the drilling rod is in a rotating state while going deeper, which is more convenient for the drilling rod to go deeper. This combination of rotation and deep drilling improves the penetration of drilling, can better cut the rock layer to facilitate sampling and measurement, improves the efficiency of drilling, and provides convenience for sampling and detection of turbidite layer thickness.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the pressing assembly includes a cylinder 5 installed on the top of the second drilling rod 3, a pressure plate 6 installed on the bottom end of the piston rod of the cylinder 5, an insert block 14 rotatably connected to the bottom of the pressure plate 6, and a fixing frame 4 fixedly connected to the top of the base 1 and having an L-shaped structure.

[0039] After the second drilling rod 3 is connected to the first drilling rod 2, the pressing plate 6 is rotated so that the plug 14 is located at the top of the second drilling rod 3. The cylinder 5 is operated to push the pressing plate 6 downward, so that the plug 14 is inserted into the second drilling rod 3, and the connection between the second drilling rod 3 and the cylinder 5 can be achieved.

[0040] like Figure 1 and Figure 2 As shown, the pulling assembly includes a connecting rope 13 fixedly connected to the top of the first drilling rod 2 and a control assembly for retracting and releasing the connecting rope 13. The connecting rope 13 is a steel rope to ensure sufficient strength.

The movable end of the connecting rope 13 is inserted into the guide ring 30 and connected to the winch 17. A certain margin is provided in a section of the connecting rope 13 between the guide ring 30 and the top of the second drilling rod 3. This margin ensures that the section of the connecting rope 13 between the guide ring 30 and the second drilling rod 3 has sufficient length, so that the connecting rope 13 can freely follow the second drilling rod 3 to move.

[0041] When the first drilling rod 2 and the second drilling rod 3 are lowered, the connection rope 13 is lowered by the cooperation of the winch 17. After the drilling is completed and the sedimentary rock samples are obtained, the winch 17 is operated to reel in the connection rope 13, which can drive the first drilling rod 2 and the second drilling rod 3 to move upward for removal, making the removal of the drilling rods and the internal samples simpler and more efficient.

[0042] like Figure 4 and Figure 6 As shown, the connecting assembly includes a first positioning block 19 fixedly connected to the bottom of the second drilling rod 3 and a second bolt 28 inserted into the first positioning block 19, and the second bolt 28 is threadedly connected to one side of the first drilling rod 2 near the top.

[0043] The first drilling rod 2 and the second drilling rod 3, and the second drilling rod 3 and the second drilling rod 3 can be connected by the cooperation of the first positioning block 19 and the second bolt 28. The connection is stable, and the disassembly and assembly is simple and convenient.

[0044] like Figure 3 and Figure 5As shown, in order to position the connecting rope 13 to the outside of the second drilling rod 3, a positioning assembly is provided on the outside of the second drilling rod 3 and close to the top. The positioning assembly is used to position the connecting rope 13 to the outside of the second drilling rod 3. The positioning assembly includes a placement groove 15 opened on the outside of the second drilling rod 3 and close to the support plate 29, a second positioning block 12 and a first bolt 27 inserted into the second positioning block 12.

The second positioning block 12 is installed on the outside of the second drilling rod 3 by the first bolt 27.

[0045] When the connecting rope 13 is located inside the placement groove 15, the second positioning block 12 is fastened to the outside of the second drilling rod 3 by the first bolt 27, which can ensure the stable position of the connecting rope 13, so that the connecting rope 13 is located inside the placement groove 15 to avoid the connecting rope 13 moving between the second drilling rod 3 and the drill hole, thereby affecting the smooth rotation operation of the second drilling rod 3.

[0046] like Figure 5 and Figure 6 As shown, a second embedding groove 20 is provided on the outer surface of the first drilling rod 2 and the second drilling rod 3 and on one side close to the top, the first positioning block 19 and the second bolt 28 are both located inside the second embedding groove 20, a first embedding groove 18 is provided on the outer surface of the second drilling rod 3 and on one side close to the top, the second positioning block 12 is located inside the first embedding groove 18, and the first bolt 27 is located inside the second positioning block 12.

[0047] When the connecting rope 13, the first positioning block 19, the second positioning block 12, the first bolt 27 and the second bolt 28 are installed, a hidden installation is achieved, which is convenient for ensuring the flatness of the surface of the first drilling rod 2 and the second drilling rod 3, so that the first drilling rod 2 and the second drilling rod 3 can be smoothly drilled.

[0048] Working principle:

[0049] The base 1 is placed in the geological area to be explored, the slide groove 16 on the outside of the first drilling rod 2 is plugged into the slider 25 of the turntable 8, and the pressing plate 6 is rotated so that the plug 14 is located at the top of the first drilling rod 2. The cylinder 5 is operated to push the pressing plate 6 downward, so that the plug 14 is plugged into the inside of the first drilling rod 2, and the connection between the first drilling rod 2 and the cylinder 5 can be realized. The cylinder 5 is operated to push the pressing plate 6 and the first drilling rod 2 at the bottom thereof downward, so that the in-depth sampling of the drilling rod can be carried out;

[0050] As the drilling rod moves downward, the motor 11 runs, and the motor 11 drives the rotating rod 21 to rotate. The rotating rotating rod 21 can realize the rotation of the connecting rod 10 and the displacement operation. The moving connecting rod 10 can better drive the rack 22 to move horizontally. When the rack 22 moves, the rotating disk 8 can be rotated through the gear ring 23. When the rotating rod 21 continues to rotate, the connecting rod 10 reciprocates left and right, thereby realizing the reciprocating movement of the rack 22, so that the drilling rod is in a rotating state while it moves deeper, which is more convenient for the drilling rod to go deeper;

[0051] According to the sampling depth, the second drilling rod 3 is connected to the first drilling rod 2, and the second drilling rods 3 are connected to each other, and the drilling depth is recorded, and in-depth sampling can be carried out;

[0052] After drilling is completed and sedimentary rock samples are obtained, the winch 17 is operated to reel in the connecting rope 13, which can drive the first drilling rod 2 and the second drilling rod 3 to move upward for removal. The removal of the drilling rod and the internal samples is simpler and more efficient. The turbidite sample is taken out from the inside of the drilling rod for measurement, and the thickness of the turbidite layer can be accurately obtained. The measurement is more convenient, which improves the quality and accuracy of the data and meets the high-precision requirements of geological research and engineering applications.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
