Furthermore, a drill bit 8 is connected to the bottom of the motor 2, wherein the motor 2 can be connected to the drill bit 8 via a coupling, and when the motor 2 is started, the motor 2 can drive the drill bit 8 to rotate.

[0034] Further, the soil inlet pipe 3 is connected to the bottom of the housing 1, and the discharge pipe 9 is connected to the side of the soil inlet pipe 3. When the drill bit 8 rotates, the soil enters the soil inlet pipe 3 and moves upward, and then is discharged from the discharge pipe 9, completing the sampling.

[0035] The fixture 5 is sleeved on the outer surface of the soil inlet pipe 3, the adjusting device 4 is embedded in the inside of the fixture 5, the base 6 is arranged below the fixture 5, and the reinforcement device 7 is connected to the bottom of the base 6, wherein the adjusting device 4 is connected to the base 6 so that the base 6 can move up and down to adjust the sampling height.

[0036] Specifically, when using the sampling mechanism of the embodiment of the present invention to sample the weak layer of the slope of an open-pit coal mine, the sampling mechanism is placed in a designated position, and the base 6 can be moved up and down by operating the adjustment device 4 to adjust the sampling height of the sampling mechanism, and the adjustment device 4 can position the height of the base 6, and the height adjustment operation is simple and convenient. After that, the sampling mechanism is pressed down again, so that the reinforcement device 7 falls to the ground to support the sampling mechanism, and the reinforcement device 7 can contact the ground to form a stable support structure. The sampling mechanism will not change the sampling height of the sampling mechanism after completing the height adjustment, and the use effect is good. When the motor 2 is started, the motor 2 drives the drill bit 8 to rotate, and the soil enters the soil inlet pipe 3 and moves upward, and then is discharged from the discharge pipe 9 to complete the sampling.

[0037] According to one embodiment of the present invention, Figures 1 to 3 As shown, there are two groups of adjusting devices 4, which are symmetrically arranged inside the fixing device 5, and each group of adjusting devices 4 includes: a disassembly assembly 41, which is installed inside the fixing device 5; a clamping block 45, which is embedded in the fixing device 5; a control rod 42, which is connected to the outer side of the clamping block 45; a first spring 46, which is sleeved on the surface of the control rod 42 inside the fixing device 5; a sliding rod 44, which has a tooth groove 43 on its surface, which is meshed with the clamping block 45, and the sliding rod 44 is connected to the top of the base 6.

[0038] Specifically, refer to Figures 1 to 3 By pulling the control rod 42, the block 45 can be driven to separate from the tooth groove 43. After the block 45 is separated from the tooth groove 43, the block 45 is slidably connected between the slide bar 44 and the holder 5, so that the base 6 can move up and down, thereby adjusting the sampling height of the sampling mechanism. Under the elastic force of the first spring 46, the block 45 and the tooth groove 43 are tightly engaged, so that the height of the base 6 can be positioned, making the height adjustment operation simple and convenient.

[0039] According to one embodiment of the present invention, Figure 2 As shown, the clamping block 45 and the inner groove of the fixer 5 are both square structures, and the surface of the clamping block 45 fits tightly with the inner groove wall of the fixer 5 .

[0040] Further, according to an embodiment of the present invention, the sliding rod 44 is in an L-shaped structure.

[0042] According to one embodiment of the present invention, Figure 3 and Figure 4 As shown, the disassembly and assembly component 41 includes: a fixing cylinder 415, which is installed inside the fixer 5; a fixing rod 413, which is embedded in the fixing cylinder 415; a sleeve block 417, which is sleeved on the surface of the fixing rod 413; a second spring 416, which is arranged on the outside of the sleeve block 417; and a fixing groove 411, which is opened on the surface of the soil inlet pipe 3.

[0043] Specifically, by pulling the fixing rod 413, the fixing rod 413 can be separated from the fixing groove 411, so that the fixer 5 can be disassembled and the fixer 5 can be separated from the soil inlet pipe 3, and the disassembly and assembly operation is simple and convenient for regular inspection and maintenance. Further, under the elastic force applied by the second spring 416 to the sleeve block 417, the fixing rod 413 and the fixing groove 411 are tightly plugged, so that the fixer 5 is firmly installed and positioned.

[0044] According to one embodiment of the present invention, the fixing rod 413 and the fixing groove 411 are connected in a plug-in type structure, and the fixing device 5 and the soil inlet pipe 3 are connected in a split type structure. Thus, the plug-in structure between the fixing rod 413 and the fixing groove 411 is used to disassemble and assemble the fixing device 5, which is simple to disassemble and assemble and is more convenient and labor-saving to use.

[0048] Furthermore, the number of the burying rods 73 is 4, and the burying rods 73 are arranged at equal distances at the four corners of a square.

[0049] Specifically, the sampling mechanism is placed at a designated position, the sampling mechanism is pressed down so that the burying rod 73 is inserted into the soil, and then the stabilizing plate 72 connected to the connecting rod 71 at the bottom of the base 6 is dropped to the ground, thereby supporting the sampling mechanism. The stabilizing plate 72 contacts the ground to form a stable supporting structure. After the height adjustment is completed, the sampling height of the device will not change, so that the use effect of the weak layer sampling device of the open-pit coal mine slope can be better.

[0051] When in use, after placing the sampling mechanism at the designated position, the control rod 42 can be pulled to drive the block 45 to separate from the tooth groove 43. After the block 45 is separated from the tooth groove 43, the block 45 is slidably connected between the slide bar 44 and the fixture 5, so that the base 6 can move up and down, thereby adjusting the sampling height of the sampling mechanism. Under the elastic force of the first spring 46, the block 45 and the tooth groove 43 are tightly meshed, so that the height of the base 6 can be positioned, and the sampling mechanism is pressed down to insert the soil rod 73 into the soil, and then the stabilizing plate 72 connected to the connecting rod 71 at the bottom of the base 6 is landed, thereby supporting the sampling mechanism. The stabilizing plate 72 contacts the ground to form a stable supporting structure. After the sampling mechanism completes the height adjustment, the sampling height of the device will not change, which can make the use effect of the weak layer sampling device of the open-pit coal mine slope better. By pulling the fixing rod 413, the fixing rod 413 can be separated from the fixing groove 411, so that the fixer 5 can be disassembled and the fixer 5 can be separated from the soil inlet pipe 3. The disassembly and assembly operation is simple and convenient for regular inspection and maintenance. Further, under the elastic force applied by the second spring 416 to the sleeve block 417, the fixing rod 413 and the fixing groove 411 are tightly plugged, so that the fixer 5 is firmly installed and positioned. When the motor 2 is started, the motor 2 drives the drill bit 8 to rotate, and the soil enters the soil inlet pipe 3 and moves upward, and then is discharged from the discharge pipe 9 to complete the sampling.
