[0035] In order to make the purpose, scheme and advantages of the technical solution of this application clearer, the following will be combined with the drawings of the specific embodiments of this application to clearly and completely describe the technical solution of the embodiment of this application. Unless otherwise specified, the terms used in this article have the common meanings in the art. The same reference numerals in the drawings represent the same components.

[0036] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0037] As described above, in traditional rock sampling experiments, since traditional fixtures require screwing multiple bolts to fix the sampled rock, when the drilling position needs to be adjusted, each bolt needs to be removed and the sampled rock needs to be re-fixed, which makes rock fixation inconvenient.

[0038] In order to at least partially solve one or more of the above-mentioned problems and other potential problems, an example embodiment of the present application provides a laboratory rock continuous core sampling device, which includes a sampling box; a telescopic drill, which is arranged on the top surface of the sampling box, and the drill bit is arranged vertically downward; a cross slide, which is arranged on the bottom surface of the sampling box; and a clamp, which is slidably arranged on the surface of the cross slide, so that the rock can be fixed and the sampling position can be changed in a portable manner.

[0039] The following is an illustrative description of the laboratory rock continuous core sampling device according to an embodiment of the present application with reference to the accompanying drawings. Figure 1 A schematic structural diagram of a continuous coring device according to an embodiment of the present application is shown. Figure 2 A schematic structural diagram of a sampling box 1 according to an embodiment of the present application is shown.

[0040] In some embodiments, a laboratory rock continuous core sampling device includes: a sampling box 1; and a telescopic drill 2, which is arranged on the top surface of the sampling box 1, with the drill bit arranged vertically downward; a cross slide 3, which is arranged on the bottom surface of the sampling box 1; and a clamp 4, which is slidably arranged on the surface of the cross slide 3.

[0041] During use, the rock to be sampled is fixed by the clamp 4, the telescopic drill 2 is started, and the surface of the sampled rock is drilled and cored. Then, the clamp 4 is moved on the surface of the cross slide 3, so that the relative position of the telescopic drill 2 and the sampled rock changes, and the telescopic drill 2 is started again to drill and coring, thereby achieving the purpose of completing multiple consecutive samplings with a single fixation.

Finally, the drawer panel 12 is pushed into the box body 11 and covered with the transparent front panel 13 to complete the installation of the rock. The transparent front panel 13 is used to observe the rock drilling situation in the box body 11.

[0046] In some embodiments, the telescopic drill 2 includes: a drill bit adjustment rail 21, which is arranged on the top surface of the box body 11; and an electric telescopic rod 22, the installation end of which is slidably connected to the drill bit adjustment rail 21, and the telescopic end faces the drawer panel 12; an electric drill 23, which is installed at the telescopic end of the electric telescopic rod 22.

[0047] During use, the drill bit adjustment track 21 is in the same direction as one of the slide rails of the cross slide 3. In this way, when adjusting the position of the clamp 4 on the surface of the cross track, the adjustment range of the drill bit position can also be increased by adjusting the position of the electric drill 23 on the drill bit adjustment track 21. After starting the electric drill 23, the electric telescopic rod 22 is extended and retracted to drive the drill bit of the electric drill 23 into the rock surface.
