[0028] An electric telescopic rod 6 is installed at the middle of the bottom surface of the first mounting plate 1 by screws, a fixing block 7 is installed at the bottom of the electric telescopic rod 6 by screws, a mounting frame 8 is slidably connected to the outer side of the fixing block 7, a spring telescopic rod 9 is installed at one end of the mounting frame 8 by screws, an insertion frame 10 is installed at one end of the spring telescopic rod 9 by screws, a sampling tube 19 is rotatably connected to the bottom of the mounting frame 8, a threaded rod 12 is threadedly connected to one end of the sampling tube 19, and a limit plate 11 is rotatably connected to the bottom of the threaded rod 12;

[0029] The outer diameter of the limit plate 11 is equal to the inner diameter of the sampling tube 19, the bottom of the sampling tube 19 is provided with an inclined angle, the inner diameter of the mounting frame 8 is equal to the outer diameter of the fixing block 7, the insertion frame 10 passes through the mounting frame 8 and is located inside the fixing block 7, and one end of the top of the insertion frame 10 is provided with an inclined angle;

[0030] A driving motor 13 is installed at one end of the bottom of the first mounting plate 1 by screws, and the output shaft of the driving motor 13 is fixedly connected to the rotating shaft 14, and driving rings 21 are welded at both ends of the outer side of the rotating shaft 14, and a rubber tube 15 is bonded to the outer side of the driving ring 21. A spring telescopic column 16 is installed at the bottom of one driving ring 21 by screws, and a driving ring 21 is provided at one end of the bottom of the spring telescopic column 16. The fixed end and the bottom of the movable end of the spring telescopic column 16 are both installed with a magnetic ring 18 by screws;

[0031] The two magnetic circles 18 are attracted to each other, and the rubber tube 15 is in compression contact with the sampling tube 19 .

[0032] After the personnel move the first mounting plate 1 and the second mounting plate 2 to the appropriate position, they adjust the positions of the first mounting plate 1 and the second mounting plate 2 according to the terrain, and then fix the first mounting plate 1 and the second mounting plate 2 by squeezing the nut 4. Then the personnel insert the insertion rod 5 into the soil and fix the first mounting plate 1 and the second mounting plate 2 on the top of the soil, which is convenient for the personnel to fix the sampling device, improves the efficiency of fixing the sampling device, and ensures the stability of the sampling device when it is used. It can be applied to rock and soil sampling in different terrains, expanding the application range of the sampling device;

[0033] Then, according to the rock and soil depth to be sampled, the personnel rotate the threaded rod 12 to push the limit plate 11 to move inside the sampling tube 19, locate the sampling depth, and ensure the effect of rock and soil sampling. The personnel move the sampling tube 19 to move the installation frame 8 to the outside of the fixed block 7.

The sampling tube 19 can rotate when it moves, making it easier to insert the sampling tube 19 into the soil.

[0035] As the electric telescopic rod 6 is opened, the sampling tube 19 is inserted into the soil to achieve rock and soil sampling. After the sampling is completed, the personnel disassemble the sampling tube 19, and then rotate the threaded rod 12 to push the limit plate 11 to move inside the sampling tube 19, and push the rock and soil samples out of the sampling tube 19, which facilitates the unloading of the rock and soil samples and improves the efficiency of the unloading of the rock and soil samples. After the sampling is completed, the two magnetic circles 18 are adsorbed on each other, so that the moving end of the spring telescopic column 16 does not contact the ground.
