[0035] Please refer to Figures 1 to 3 . This application embodiment provides an orifice fine-tuning device, including: bottom plate 1, first flat plate 2, second flat plate 3, third flat plate 4, first spacer 5, second spacer 6 and orifice tube 8.

[0036] Among them, two bottom plates 1 are arranged in parallel, and the bottom plate 1 extends along the first direction X. The first flat plate 2 is connected to the bottom plate 1. The first cushion block 5 is fixedly connected to the upper surface of the first flat plate 2. The second flat plate 3 is located above the first flat plate 2. One end of the second flat plate 3 along the first direction X is rotatably connected to the first cushion block 5, and the other end is movably and fixedly connected to the first flat plate 2. The second cushion block 6 is fixedly connected to the upper surface of the second flat plate 3. The third flat plate 4 is located above the second flat plate 3. One end of the third flat plate 4 along the second direction Y is rotatably connected to the second cushion block 6, and the other end is movably and fixedly connected to the second flat plate 3. The second direction Y is perpendicular to the first direction X. The orifice tube 8 is fixedly connected to the upper surface of the third flat plate 4. In this embodiment, both the first direction X and the second direction Y are parallel to the upper plane of the first flat plate 2. In this embodiment, the up and down direction is based on the upper plane of the first flat plate 2, that is, the upper plane of the first flat plate 2 is the horizontal plane, and the direction perpendicular to the upper plane of the first flat plate 2 is the up and down direction.

[0037] For the orifice fine-tuning device provided in this embodiment, by arranging two bottom plates 1 extending along the first direction X, the whole device can be installed near the orifice. One end of the second flat plate 3 along the first direction X is rotatably connected to the first cushion block 5, and the other end is movably and fixedly connected to the first flat plate 2. Thus, the second flat plate 3 can rotate relative to the first flat plate 2 around the axis extending in the second direction Y to adjust the inclination angle of the orifice tube 8 in the first direction X; one end of the third flat plate 4 along the second direction Y is rotatably connected to the second cushion block 6, and the other end is movably and fixedly connected to the second flat plate 3. Thus, the third flat plate 4 can rotate relative to the second flat plate 3 around the axis extending in the first direction X to adjust the inclination angle of the orifice tube 8 in the second direction Y. The drill bit of the drill can enter the orifice through the orifice tube 8 for core sampling. Therefore, by adjusting the inclination angles of the orifice tube 8 in the first direction X and the second direction Y, the core sampling angle at the orifice can be adjusted to ensure that the inclination degree during the drill entering the hole meets the requirements.

[0038] In this embodiment, as Figure 1 shown, the number of the first cushion blocks 5 is two, and the two first cushion blocks 5 are spaced apart along the second direction Y. The first cushion block 5 and the second flat plate 3 are rotatably connected by a first hinge 9. The axis of the first hinge 9 extends along the second direction Y, so that the second flat plate 3 can rotate relative to the first flat plate 2 around the axis of the first hinge 9.

[0039] Specifically, as Figure 1 and Figure 2As shown, a first limiting portion 11 is provided on the upper surface of the first flat plate 2, and a first fixing portion (not shown in the figure) is provided on the second flat plate 3. The first fixing portion is detachably connected to a first movable member 15, and the bottom end of the first movable member 15 is limited by the first limiting portion 11. The number of the first movable members 15 is two, and the two first movable members 15 are spaced apart along the second direction Y. The first movable member 15 and the first cushion block 5 are spaced apart along the first direction X. The first fixing portion can be a bolt, and the first movable member 15 can be a T-shaped rod. The two short rods at the bottom of the first movable member 15 are limited by the first limiting portion 11 and cannot move but can rotate. The long straight rod above the first movable member 15 is detachably and fixedly connected to the first fixing portion of the second flat plate 3. When the angle of the second flat plate 3 needs to be adjusted, the first fixing portion is disassembled, the first hinge 9 is rotated, and the first movable member 15 rotates accordingly. After the angle adjustment of the second flat plate 3 is completed, the first fixing portion is reinstalled.

[0040] In this embodiment, the first movable member 15 and the first hinge 9 allow the second flat plate 3 to rotate relative to the first flat plate 2 by ±10°, and can adjust the inclination angle of the orifice tube 8 in the first direction X to meet the requirements. ±10° is based on the upper plane of the first flat plate 2, that is, parallel to the upper plane of the first flat plate 2 is 0°, upward rotation is positive, and downward rotation is negative.

[0041] In this embodiment, the number of the second cushion blocks 6 is two, and the two second cushion blocks 6 are spaced apart along the first direction X. The second cushion block 6 and the third flat plate 4 are rotatably connected by a second hinge 10. The axis of the second hinge 10 extends along the first direction X, so that the third flat plate 4 can rotate relative to the second flat plate 3 around the axis of the second hinge 10.

[0042] Specifically, as Figure 1 and Figure 3As shown, a second limiting portion 12 is provided on the upper surface of the second flat plate 3, and a second fixing portion 14 is provided on the third flat plate 4. The second fixing portion 14 is detachably connected with a second movable member 16, and the bottom end of the second movable member 16 is limited by the second limiting portion 12. There are two second movable members 16, and the two second movable members 16 are spaced apart along the first direction X. The second movable member 16 and the second cushion block 6 are spaced apart along the second direction Y. The second fixing portion 14 can be a bolt, and the second movable member 16 can be a T-shaped rod. The two short rods at the bottom of the second movable member 16 are limited by the second limiting portion 12 and cannot move but can rotate. The long straight rod above the second movable member 16 is detachably and fixedly connected with the second fixing portion 14 of the third flat plate 4. When the angle of the third flat plate 4 needs to be adjusted, the second fixing portion 14 is disassembled, the second hinge 10 is rotated, and the second movable member 16 also rotates accordingly; after the angle adjustment of the third flat plate 4 is completed, the second fixing portion 14 is reinstalled.

[0043] In this embodiment, the second movable member 16 and the second hinge 10 allow the third flat plate 4 to rotate relative to the second flat plate 3 by ±5°, and can adjust the inclination angle of the orifice tube 8 in the second direction Y to meet the requirements. ±5° is based on the upper plane of the second flat plate 3, that is, parallel to the upper plane of the second flat plate 3 is 0°, upward rotation is positive, and downward rotation is negative.

[0044] In this embodiment, a first groove body (not shown in the figure) is provided on the bottom plate 1, and the first groove body has a first predetermined length in the second direction Y. A second groove body 18 is provided on the first flat plate 2, and the second groove body 18 has a second predetermined length in the first direction X. The first flat plate 2 and the bottom plate 1 are connected by a first bolt 19, and the first bolt 19 passes through the second groove body 18 and the first groove body. The first predetermined length and the second predetermined length can be 30 mm.

[0045] Specifically, a third cushion block 7 is fixedly connected to the bottom plate 1, the first flat plate 2 is movably connected with a second bolt 20 extending along the first direction X, and one end of the second bolt 20 can abut against the third cushion block 7. The bottom plate 1 is movably connected with a third bolt 21 extending along the second direction Y, and one end of the third bolt 21 can abut against the first flat plate 2. By adjusting the second bolt 20, the first flat plate 2 can be moved relative to the bottom plate 1 along the first direction X; by adjusting the third bolt 21, the first flat plate 2 can be moved relative to the bottom plate 1 along the second direction Y, so that the position of the axis of the orifice tube 8 can be adjusted to coincide with the orifice center, ensuring the accuracy of the drilling point.

[0046] As Figure 1As shown, an installation bracket 22 for installing a laser pen is installed on the orifice tube 8. After the laser pen is installed on the installation bracket 22, the laser of the laser pen coincides with the axis of the orifice tube 8. When adjusting the second bolt 20 and the third bolt 21, it is only necessary to observe whether the laser of the laser pen coincides with the orifice center.

[0047] In this embodiment, the orifice fine-tuning device further includes a water mill drill 23 fixedly installed on the third flat plate 4. After adjusting the inclination angle and the axis position of the orifice tube 8, the drill bit of the water mill drill 23 can be placed into the orifice tube 8 to start drilling, and the core drill bit can drill 5 cm.
