Among them, the driving mechanism is a motor-gear transmission drive or a motor-belt transmission drive. The housing 1 can be set as a square box with a cavity, and the driving mechanism is arranged in the cavity.

[0024] A portable geotechnical sampling device based on the above structure is used for geotechnical sampling. When sampling geotechnical materials, the serrated structure 301 contacts the geotechnical materials, the driving mechanism is activated, the driving mechanism drives the sampling pipe 3 to rotate, presses the housing 1 towards the geotechnical materials, the serrated structure 301 breaks the geotechnical materials, the sampling pipe 3 continuously penetrates into the geotechnical materials, the geotechnical sample remains in the sampling pipe 3. After the sampling pipe 3 penetrates to the set depth of the geotechnical materials, stop pressing the housing 1, take out the sampling pipe 3 in the reverse direction, push the pushing mechanism in the sampling pipe 3, and push the geotechnical sample in the sampling pipe 3 into the designated storage device to complete the geotechnical sampling. The operation is convenient. Using the portable geotechnical sampling device of this embodiment, the geotechnical sample in the sampling pipe 3 can be quickly and conveniently taken out. The pushing mechanism is used to push the sample out of the sampling pipe 3, and it is not easy to damage the geotechnical sample; the overall structure of the portable geotechnical sampling device of this embodiment is relatively small and easy to carry.

[0025] As an implementable mode, as Figure 1 , Figure 3 shown, the pushing mechanism includes a sleeve 12, a fixing plate 10, a sliding plate 14, a push rod 11, a push block 9, and a lead screw 15. The sleeve 12 is arranged at one end of the housing 1 away from the sampling end of the sampling pipe 3. The fixing plate 10 and the sliding plate 14 are respectively arranged at two ends inside the sleeve 12 close to the housing 1 and away from the housing 1. The fixing plate 10 is provided with a push rod through hole. One end of the push rod 11 is fixedly connected to the sliding plate 14, and the other end of the push rod 11 passes through the push rod through hole and is fixedly connected to the push block 9. The radial dimension of the push block 9 is larger than the radial dimension of the push rod through hole, and the radial dimension of the push block 9 is smaller than the radial dimension of the sampling pipe 3. The push block 9 is arranged opposite to the pipe orifice of the sampling pipe 3. The sliding plate 14 is provided with a threaded hole that cooperates with the lead screw 15. One end of the sleeve 12 away from the housing 1 is provided with a cover plate. The cover plate is provided with a lead screw through hole. One end of the lead screw 15 passes through the lead screw through hole and is rotatably connected to the cover plate, and the other end of the lead screw 15 passes through the threaded hole and is rotatably connected to the fixing plate 10.

[0026] The fixed plate 10 is fixedly arranged inside the lower end of the sleeve 12. The sliding plate 14 is slidably sleeved inside the upper end of the sleeve 12. The lower end of the lead screw 15 is fixedly connected to the fixed plate 10, and the upper end of the lead screw 15 is threadedly connected to the threaded hole of the sliding plate 14. The lower end of the push rod 11 passes through the push rod through hole of the fixed plate 10 and is fixedly connected to the push block 9, and the upper end of the push rod 11 is fixedly connected to the sliding plate 14. Before sampling the rock and soil, rotate the lead screw 15 in the reverse direction, driving the sliding plate 14 to move upward inside the sleeve 12, driving the push rod 11 to move upward, driving the push block 9 to move upward until the push block 9 is located inside the sleeve 12 and directly above the pipe orifice of the sampling pipe 3; the sampling pipe 3 penetrates into the rock and soil to sample the rock and soil; when it is necessary to push out the rock and soil sample inside the sampling pipe 3, rotate the lead screw 15 in the forward direction, driving the sliding plate 14 to move downward inside the sleeve 12, driving the push rod 11 to move downward, driving the push block 9 to move downward, and the push block 9 enters the sampling pipe 3. As the lead screw 15 is continuously rotated in the forward direction, the push block 9 continuously penetrates into the sampling pipe 3 until the rock and soil sample is completely pushed out of the sampling pipe 3; then rotate the lead screw 15 in the reverse direction to make the push block 9 located inside the sleeve 12 for the next rock and soil sampling. The structure is simple and the operation is convenient. The pushing mechanism composed of the sleeve 12, the fixed plate 10, the sliding plate 14, the push rod 11, the push block 9, and the lead screw 15 pushes the sample out of the sampling pipe 3, and it is not easy to damage the rock and soil sample.

[0027] Preferably, as Figure 1 shown, opposite handles 16 are provided on the side wall of the sleeve 12.

[0028] Two opposite handles 16 are provided on the sleeve 12, which is convenient for the user to grip and apply force.

[0030] The setting of the handwheel 1 is convenient for the user to grip and apply force when rotating the lead screw 15. Just rotating the handwheel 13 can achieve rotating the lead screw 15, which is very convenient.

The first gear 7 is sleeved and fixed on the output shaft of the motor 8. The second gear 6 is sleeved and fixed on the sampling pipe 3. The first gear 7 and the second gear 6 are meshed. The motor 8 is electrically connected to the storage battery 2.

[0032] The motor 8 starts to work, the output shaft of the motor 8 rotates, drives the first gear 7 to rotate, drives the second gear 6 to mesh and rotate, and drives the sampling tube 3 to rotate. The structure is simple, the manufacturing cost is low, multi-stage gear transmission is adopted, the transmission efficiency is high, the load is shared, the wear is reduced, and the stability is good. The setting of the storage battery 2 facilitates geotechnical sampling in places without power supply.

[0033] Preferably, as Figure 1 , Figure 2 shown, scale lines 4 are arranged along the length direction of the sampling end of the sampling tube 3.

[0034] The scale line 4 is arranged on the outer side of the sampling tube 3, which is convenient for the user to observe the depth of the sampling tube 3 penetrating into the geotechnical. After reaching the set depth, stop pressing the handle 16, which is very convenient.

[0035] Preferably, as Figure 1 shown, the sampling tube 3, the fixing plate 10, the sliding plate 14, the push rod 11 and the push block 9 are coaxial.

[0036] The sampling tube 3, the fixing plate 10, the sliding plate 14, the push rod 11 and the push block 9 being coaxial is convenient for the push block 9 to enter the sampling tube 3 more smoothly and better push out the geotechnical sample.

[0037] Preferably, as Figure 1 , Figure 2 shown, one end of the housing 1 away from the sampling end of the sampling tube 3 is provided with a thrust roller bearing 5, and the other end of the sampling tube 3 relative to the sampling end is sleeved and fixed in the thrust roller bearing 5.

[0038] The thrust roller bearing 5 is used to bear the large axial force of the sampling tube 3 during rotation and feeding, effectively improving the stability of the rotation of the sampling tube 3.

[0039] Preferably, as Figure 1 , Figure 2 shown, one end of the housing 1 close to the sampling end of the sampling tube 3 is provided with a deep groove ball bearing 17, and the sampling end of the sampling tube 3 is sleeved and fixed in the deep groove ball bearing 17.

[0040] The deep groove ball bearing 17 is used to bear the radial force of the geotechnical sample pushed out of the sampling tube 3 by the push block 9 on the sampling tube 3, effectively improving the stability of the sampling tube 3.

[0041] Wherein, the sawtooth structure 301 is arranged along the circumferential edge of the sampling end of the sampling tube 3.
