The cleaning brushes 206 are arranged at equal angles on the inner wall of the cleaning pipe 205, and the cleaning pipe 205 forms a rotating structure with the sampling depth control component 3 through the second gear 204 and the sliding rod 203. The second gear 204 meshes with the sliding rod 203, and the sliding rod 203 meshes with the first gear 202; Since there will be a lot of dirt on the part extending into the geotechnical soil during geotechnical sampling, a plurality of cleaning brushes 206 are arranged on the inner wall of the cleaning pipe 205. At the same time, the cleaning brushes 206 can drive the first gear 202 to rotate through the first motor 201. The first gear 202 drives the sliding rod 203 to slide left and right, and the sliding rod 203 drives the second gear 204 to rotate left and right, so that the cleaning brushes 206 rotate left and right, which can clean the sampling groove 304 to prevent the existence of geotechnical residues in the sampling groove 304, which may affect the judgment of the geology.

[0028] Please refer to Figure 1 As shown in Figure 3 a subway survey geotechnical sampling device, the sampling depth control component 3 includes a second motor 301, a third gear 302, a lifting rod 303, a sampling groove 304, and a limiting rod 305, which can control the depth of the sampling groove 304 so as to sample geotechnical materials at different depths as needed. The lifting rod 303 forms a lifting structure with the sampling device base 1 through the third gear 302, and the lifting rod 303 meshes with the third gear 302; the second motor 301 drives the third gear 302 to rotate, and at the same time the third gear 302 drives the lifting rod 303 to rise or fall within the limiting rod 305. Therefore, the sampling groove 304 opened on the side of the lifting rod 303 can rise or fall, so as to control the depth of the sampling groove 304 and sample geotechnical materials at different depths as needed.

[0029] Please refer to Figure 1 and Figure 4 As shown in Figure 5 a subway survey geotechnical sampling device, the sampling device fixing component 4 includes a support rod 401, a connecting rod 402, a connecting ear 403, a rotating shaft 404, a connecting block 405, a limiting rod 406, a threaded rod 407, a rotating ball 408, and a top block 409. The device can adapt to uneven road surfaces and can fix the device stably. The connecting block 405 forms a rotating structure with the connecting rod 402 through the rotating shaft 404, and the connecting block 405 forms a detachable structure with the connecting rod 402 through the connecting ear 403 and the limiting rod 406. Moreover, the support rod 401, the connecting rod 402, and the sampling device base 1 form a right-angled triangle with the sampling device base 1 and the connecting rod 402 as the right-angled sides. The top block 409 forms a lifting structure with the sampling device base 1 through the threaded rod 407, and the threaded rod 407 is threadedly connected to the connecting block 405; by turning the threaded rod 407 to control the lifting of the top block 409, the device can adapt to uneven road surfaces and can fix the device stably. At the same time, the sampling device base 1, the support rod 401, and the connecting rod 402 form a right-angled triangle, making the device more stable when fixed, and it can be folded for convenient storage, making the device more practical.

[0030] Working principle: First, move the device to the location to be surveyed through the universal wheels at the bottom of the sampling device base 1. At this time, pull out the limit rod 406, and at the same time rotate the connecting block 405 so that the connecting block 405 and the connecting rod 402 are on the same horizontal line. At this time, the end of the connecting block 405 will be engaged with another lug 403 at the end of the connecting rod 402. Pass the limit rod 406 through the connecting block 405 and insert it into the engaged lug 403. At this time, the sampling device base 1, the support rod 401, and the connecting rod 402 can support the device. At the same time, rotate the threaded rod 407 according to the actual terrain of the survey. At this time, the threaded rod 407 rotates in the top block 409 through the rotating ball 408, and makes the top block 409 closely fit with the ground. At this time, the device can be firmly fixed;

[0031] Next, turn on the switch of the second motor 301. At this time, the second motor 301 will cause the third gear 302 to rotate. Since the lifting rod 303 is engaged on the side of the third gear 302, the rotating third gear 302 will drive the lifting rod 303 to descend in the limit rod 305. At this time, the depth of the sampling groove 304 opened in the lifting rod 303 can be controlled according to actual needs, so that the sampling groove 304 can sample the rock and soil at different depths. After the sampling is completed, since the second motor 301 is a servo motor, the lifting rod 303 can be controlled to rise in the limit rod 305. At this time, the obtained rock and soil samples can be placed in the sampling collection box 5. Finally, lower the lifting rod 303 into the cleaning pipe 205, and then turn on the switch of the first motor 201. At this time, the first motor 201 will drive the first gear 202 to rotate. Since the sliding rod 203 is engaged on the side of the first gear 202, the first gear 202 will drive the sliding rod 203 to slide back and forth left and right. And a second gear 204 is installed on the other side of the sliding rod 203. At this time, when the first gear 202 rotates, the second gear 204 will rotate back and forth, and at the same time, the cleaning brush 206 inside the cleaning pipe 205 can be controlled to rotate back and forth, so as to clean the sampling groove 304.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
