Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1:

[0031] like Figure 1-6As shown, the present invention provides a core sample extraction device, including a base 1 and a mounting bracket 2 fixedly installed on the top of the base 1, and a fixing rod 3 provided on the top of the base 1. A lifting component 10 is provided at the end of the fixing rod 3 away from the base 1. A mounting plate 11 is provided on the outer edge of the lifting component 10.

A limiting rod 17 adapted to the limiting groove 13 and the limiting groove 16 is inserted into the outer wall of the mounting plate 11. A core extraction component 18 is provided at the end of the mounting seat 14 away from the mounting plate 11.

[0032] Specifically, the fixing rod 3 has a positioning groove 4 and a through hole 5 at one end near the base 1. A positioning block 6 is fixedly installed on the inner wall of the mounting bracket 2, and a through hole 7 is opened on the outer wall of the mounting bracket 2. A bolt 8, which is compatible with the through hole 7 and the through hole 5, is threadedly connected to the outer wall of the mounting bracket 2. A nut 9 is threadedly connected to the outer wall of the bolt 8. The positioning block 6 and the positioning groove 4 are installed by insertion. The bolt 8 passes through the through hole 7 and the through hole 5, and the diameters of the through holes 7 and 5 are the same. The advantage is that the operator can quickly install the fixing rod 3 by inserting the positioning block 6 into the positioning groove 4, then inserting the bolt 8 through the through hole 7 and the through hole 5, and finally threading the nut 9 to the bolt 8. This facilitates quick installation and disassembly during use or assembly, making it highly practical.

[0033] Specifically, the mounting plate 11 has a U-shaped cross-section, and the guide block 15 and guide groove 12 are plugged into each other. The guide block 15 has a T-shaped cross-section. The advantage is that the operator can quickly position the mounting base 14 by inserting the guide block 15 into the guide groove 12.

[0034] Specifically, the limiting rod 17 extends through the limiting groove 13 into the limiting groove 16, and the limiting groove 13 and the limiting groove 16 have the same diameter. The advantage is that after the mounting base 14 is quickly positioned, the operator can extend the limiting rod 17 through the limiting groove 13 into the limiting groove 16, thus quickly limiting the mounting base 14 and consequently quickly limiting the core extraction assembly 18. This also facilitates maintenance after prolonged use.

[0035] Example 2:

[0036] like Figure 2-6As shown, as an improvement on the previous embodiment, to further facilitate the installation of the drill bit 1803, specifically, the core sampling assembly 18 includes a motor 1801, a mounting block 1802, a drill bit 1803, a limiting block 1804, a first threaded hole 1805, a second sliding groove 1806, a third limiting groove 1807, a second threaded hole 1808, and a second bolt 1809. The mounting block 1802 is fixedly installed at the output end of the motor 1801. The drill bit 1803 is provided at the end of the mounting block 1802 away from the motor 1801, and the limiting block is fixedly installed at the end of the mounting block 1802 close to the drill bit 1803. 1804. The mounting block 1802 has a threaded hole 1805 at one end near the drill bit 1803. The drill bit 1803 has a sliding groove 1806, a limiting groove 1807, and a threaded hole 1808 at one end near the mounting block 1802. A bolt 1809, matching the threaded hole 1808 and threaded hole 1805, is threadedly connected to the end of the drill bit 1803 near the mounting block 1802. The limiting block 1804 is inserted into the sliding groove 1806, which communicates with the limiting groove 1807. The limiting block 1804 is compatible with the limiting groove 1807. The advantage is that the operator inserts the limiting block 1804 into the sliding groove 1806, and then rotates the drill bit 1803 90°, causing the limiting block 1804 to engage with the limiting groove 1807, thus achieving rapid positioning of the drill bit 1803.

[0037] Specifically, bolt 1809 extends through threaded hole 1808 into threaded hole 1805, with threaded hole 1808 having the same diameter as threaded hole 1805. The advantage is that after quickly positioning drill bit 1803, the operator can quickly install drill bit 1803 by extending bolt 1809 through threaded hole 1808 into threaded hole 1805. This facilitates quick assembly and disassembly during use, making it highly practical. During use, the operator starts motor 1801, and the output shaft of motor 1801 rotates, driving mounting block 1802 to rotate, thereby rotating drill bit 1803. Combined with lifting assembly 10, rapid core extraction can be achieved, further enhancing its practicality.

[0038] Specifically, the lifting component 10 includes a movable slot 1001, a screw rod 1002, a connecting block 1003, a slider 1004, and a first sliding slot 1005. The screw rod 1002 is rotatably installed inside the movable slot 1001. The outer wall of the screw rod 1002 is threadedly connected to the connecting block 1003. A slider 1004 is fixedly installed on one side of the mounting plate 11 close to the slider 1004. A first sliding slot 1005 is provided on one side of the fixed rod 3 away from the mounting plate 11. The connecting block 1003 and the mounting plate 11 are fixedly installed, and the slider 1004 is slidably connected to the first sliding slot 1005. The cross-section of the slider 1004 is in an "L" shape structure. The advantage is that during use, the staff rotates the screw rod 1002. The rotation of the screw rod 1002 drives the connecting block 1003 to move, thereby driving the core-taking component 18 to move. At the same time, the slider 1004 slides inside the first sliding slot 1005, enabling the rapid lifting and lowering of the core-taking component 18.

[0039] Working principle: During installation, the staff inserts the positioning block 6 into the positioning slot 4, then passes the first bolt 8 through the second through hole 7 and the first through hole 5, and finally threadedly connects the nut 9 to the first bolt 8, which can achieve the rapid installation of the fixed rod 3. During use or assembly, it is convenient for rapid disassembly and assembly, and has high practicability. Subsequently, the staff inserts the guiding block 15 into the guiding slot 12 to achieve the rapid positioning of the mounting seat 14. After the rapid positioning of the mounting seat 14, the staff passes the limiting rod 17 through the first limiting slot 13 and extends it into the second limiting slot 16 to achieve the rapid limiting of the mounting seat 14, thereby achieving the rapid limiting of the core-taking component 18. After long-term use, it is convenient for maintenance. The staff inserts the limiting block 1804 into the second sliding slot 1806, and then rotates the drill 1803 by 90°, so that the limiting block 1804 is stuck into the third limiting slot 1807 to achieve the rapid positioning of the drill 1803. After the rapid positioning of the drill 1803, the staff passes the second bolt 1809 through the second threaded hole 1808 and extends it into the first threaded hole 1805 to achieve the rapid installation of the drill 1803. During use or assembly, it is convenient for rapid disassembly and assembly, and has high practicability. During use, the staff starts the motor 1801. The output shaft of the motor 1801 rotates to drive the mounting block 1802 to rotate, thereby driving the drill 1803 to rotate. At the same time, the staff rotates the screw rod 1002. The rotation of the screw rod 1002 drives the connecting block 1003 to move, thereby driving the core-taking component 18 to move. At the same time, the slider 1004 slides inside the first sliding slot 1005, enabling the rapid lifting and lowering of the core-taking component 18, and thus achieving rapid core-taking, with high practicability.
