[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Embodiment 1:

[0032] As Figures 1-3 shown, a geological sampling device includes a carrier table 1 and a sampling assembly 2 disposed within the carrier table 1.

[0033] The sampling assembly 2 includes an outer cylinder 4 and an inner cylinder 5 fixed to the inner wall of the outer cylinder 4. A cavity is formed between the outer cylinder 4 and the inner cylinder 5, and multiple limiting assemblies are disposed within the inner cylinder 5. The limiting assembly includes a baffle 10 and a receiving groove 11. The baffle 10 is rotatably connected to the inner wall of the receiving groove 11 through a rotating shaft 9, and a driving assembly for driving the baffle 10 to rotate is disposed within the cavity.

[0034] Insert the outer cylinder 4 and the inner cylinder 5 together into the soil. The sample to be collected will enter into the inner cylinder 5. Then, use the driving assembly to push the baffle 10 to rotate into the inner cylinder 5 with the axis of the rotating shaft 9 as the center of rotation, so that the baffle 10 can hold the sample. At this time, pull the outer cylinder 4 and the inner cylinder 5 upward, and the sample will be taken out accordingly.

[0035] By setting the baffle 10 in this device and using the driving assembly to make the baffle 10 rotate with the axis of the rotating shaft 9 as the center of rotation, a structure with a wider upper part and a narrower lower part is formed in the inner cavity of the inner cylinder 5. Thus, multiple baffles 10 are used to hold the sample, preventing the sample from slipping out of the inner cylinder 5, thereby achieving the effective collection of the sample.

[0036] As Figure 2 、 3As shown, the driving assembly includes an air pump 7, a plurality of pistons 13, and a fixed cylinder 15. The air pump 7 is fixed to the top of the outer cylinder 4 by bolts, and the output end of the air pump 7 is communicated with the cavity through a connecting pipe 6.

[0037] The fixed cylinder 15 is fixedly connected to the inner wall of the cavity. The piston 13 is in sliding contact with the inner wall of the fixed cylinder 15. A connecting rod 12 is rotatably connected to the outer wall of the piston 13 on the side close to the baffle 10, and the other end of the connecting rod 12 is rotatably connected to the outer wall of the baffle 10.

[0038] The fixed cylinder 15 is provided with a ventilation hole, and a limiting ring 14 for limiting the piston 13 is fixedly connected to the inner wall of the fixed cylinder 15.

[0039] Start the air pump 7 to extract external air and transport it to the cavity and the fixed cylinder 15 through the connecting pipe 6. As the gas continuously enters, the piston 13 moves towards the baffle 10. Under the cooperation of the connecting rod 12, the bottom end of the baffle 10 is pushed to incline towards the inner cylinder 5, so as to support the sample with the baffle 10. When it is necessary to take out the sample from the inner cylinder 5, start the air pump 7 to extract the air in the cavity and the fixed cylinder 15, so that the piston 13 moves towards the limiting ring 14. When the piston 13 fits with the limiting ring 14, at this time, the baffle 10 is retracted into the receiving groove 11 under the drive of the piston 13 and the connecting rod 12, so that the sample is not blocked by the baffle 10 and is more easily taken out from the inner cylinder 5.

[0040] By setting the air pump 7, the piston 13 and the fixed cylinder 15, the device can make the baffle 10 rotate and incline to support the sample to avoid slipping, and can also rotate and retract into the receiving groove 11 when the sample needs to be taken out to avoid difficult sample taking. And by fixing the air pump 7 on the top of the outer cylinder 4, the problem of too long pipeline causing the extension of gas transportation and extraction time can be avoided, thus improving the efficiency of sample collection.

[0041] As Figure 5 shown, a moving assembly 3 is arranged at the bottom of the bearing platform 1. The moving assembly 3 includes a bottom plate 25 fixedly connected to the bottom of the bearing platform 1 through a plurality of connecting columns 24. An avoidance groove 26 for avoiding the outer cylinder 4 and the inner cylinder 5 is formed in the inner wall of the bottom plate 25. A plurality of universal wheels 28 are fixed to the bottom of the avoidance groove 26 by bolts. A push-pull rod 23 is fixed to the top of the bearing platform 1 by bolts.

[0042] The cooperation of the push-pull rod 23 and the universal wheels 28 can facilitate the movement of the device and increase the convenience of use of the device.

[0043] Embodiment 2:

[0044] A geological sampling device. In this embodiment, the following improvements are made on the basis of Embodiment 1. As Figure 2 、 4 、5 shown:

[0045] A threaded rod 8 is detachably installed at the top of the outer cylinder 4. A rotating cylinder 20 is rotatably connected to the inner wall of the bearing platform 1. The threaded rod 8 is threadedly connected to the inner wall of the rotating cylinder 20.

[0046] A first gear 21 is key-connected to the outer wall of the rotating cylinder 20. A second gear 22 meshes with the outer wall of the first gear 21. The second gear 22 is rotatably connected to the inner wall of the bearing platform 1 through a transmission shaft 19. A motor 18 is fixedly installed at the top of the bearing platform 1 through bolts. The output shaft of the motor 18 is fixedly connected to the transmission shaft 19 through a coupling.

[0047] A limiting plate 17 is fixed to the top of the threaded rod 8. A limiting groove 16 for limiting the limiting plate 17 is formed in the inner wall of the top of the bearing platform 1. The bottom of the outer cylinder 4 and the inner cylinder 5 are fixedly connected to the same sawtooth ring 27.

[0048] Start the motor 18 to drive the transmission shaft 19 to drive the second gear 22 to rotate. The second gear 22 drives the first gear 21 and the rotating cylinder 20 to rotate. Since the rotating cylinder 20 and the threaded rod 8 are in threaded cooperation, the threaded rod 8 can drive the outer cylinder 4, the inner cylinder 5 and the sawtooth ring 27 to move up and down in a rotational manner, so that the sawtooth ring 27 can drill into the soil faster.

[0049] By arranging the threaded rod 8, the rotating cylinder 20 and the sawtooth ring 27, the threaded rod 8 can drive the outer cylinder 4, the inner cylinder 5 and the sawtooth ring 27 to rotate and insert into the soil for sampling under the cooperation of the threaded rod 8 and the rotating cylinder 20. By rotating, it can drill into the soil faster, thereby further improving the sampling efficiency.

[0050] Working principle: When the device is in use, it is necessary to use a sampling device to take soil samples within 3 meters for various geochemical tests during ecological geological surveys. Therefore, it is necessary to use it in conjunction with a drilling device. After the hole is opened by the drilling device, the device is pushed above the hole, and the outer cylinder 4 and the inner cylinder 5 are aligned with the hole. The motor 18 is started to drive the transmission shaft 19 to drive the gear 2 22 to rotate, and the gear 2 22 drives the gear 1 21 and the rotating cylinder 20 to rotate. Since the rotating cylinder 20 and the threaded rod 8 are threadedly matched, the threaded rod 8 can drive the outer cylinder 4, the inner cylinder 5 and the serrated ring 27 to move up and down in a rotational manner, so that the serrated ring 27 can drill into the soil faster. When the soil enters the inner cylinder 5, the air pump 7 is started to blow air from the outside. The gas is extracted and transported to the cavity and the fixed cylinder 15 through the connecting tube 6. As the gas continues to enter, the piston 13 moves toward the baffle 10, and with the cooperation of the connecting rod 12, the bottom end of the baffle 10 is pushed to tilt toward the inner cylinder 5, so that the baffle 10 is used to support the sample, and then the motor 18 is started to drive the outer cylinder 4 and the inner cylinder 5 to rise and escape from the hole; when the sample needs to be taken out of the inner cylinder 5, the air pump 7 is started to extract the air in the cavity and the fixed cylinder 15, so that the piston 13 moves toward the limit ring 14. When the piston 13 and the limit ring 14 are in contact, the baffle 10 is retracted into the receiving groove 11 driven by the piston 13 and the connecting rod 12, so that the sample is not blocked by the baffle 10 and is easier to be taken out of the inner cylinder 5.

[0051] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
