Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to a soil sampling device for geological survey. Background Art

[0002] In geological surveys, soil sampling and testing is an important means to understand underground structures and stratum composition. Traditional soil sampling methods mainly rely on manual operations, such as inserting a drill rod or sampler directly into the soil from the surface and extracting samples. This method has problems such as sample mixing, low sampling efficiency, and difficulty in operation, especially in areas with complex geological conditions or hard strata. In order to overcome these shortcomings, automated equipment and more sophisticated soil sampling devices have been developed in recent years.

[0003] A Chinese patent with publication number CN220170581U discloses a soil sampling device for geological surveys. The device starts a hydraulic rod to move the sampling bucket downward, and a motor drives the auger to rotate. The auger drives the soil sample upward during rotation, thereby collecting the soil. Subsequently, a container is placed under the sampling bucket, and the motor drives the auger to reverse, discharging the sampled soil. Although this method enables soil sampling through automated equipment, the soil in the sampling bucket mixes when discharged, preventing workers from separately sampling soil from different layers, resulting in inaccurate test results. Utility Model Content

[0004] In response to the deficiencies in the prior art, the utility model provides a soil sampling and taking device for geological survey, which solves the problem in the prior art that soil from different strata is mixed together when the sampling tube takes out the soil and discharges it, resulting in inaccurate detection results.

After the sampling is completed, the hydraulic rod drives the top plate to rise again to lift the sampling barrel. During this process, the cleaning assembly cleans the outside of the sampling barrel. The subsequent staff unlocks the closed door through the locking assembly and opens the closed door at different positions, thereby taking out the soil from different depths to test the soil in different strata, ensuring the accuracy of the test results.

[0007] Furthermore, the rotating assembly includes: an outer ring gear, which is fixedly mounted on the outer wall of the sampling tube, a second motor is fixedly installed on the top of the top plate, and a gear is provided after the output end of the second motor passes vertically downward through the top plate, and the gear is engaged with the outer ring gear.

[0008] Furthermore, each locking assembly includes: a locking plate, which is fixedly connected to the free end of the closed door, a threaded hole is provided on the locking plate, and a plurality of receiving grooves corresponding to the locking plate are provided on the outer wall of the sampling tube, and the locking plate is locked in the receiving groove by bolts.

DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-3 As shown, the embodiment of the present invention proposes a soil sampling and taking device for geological survey, including a base plate 1, a spiral blade 5 and a cleaning assembly. The bottom of the base plate 1 is provided with a universal wheel, the top of the base plate 1 is provided with a plurality of hydraulic rods 2, and the top of the hydraulic rod 2 is supported by a top plate 3. A sampling barrel 4 is rotatably provided at the bottom of the top plate 3, and a rotating assembly for driving the sampling barrel 4 to rotate is provided on the top plate 3. A through hole for the sampling barrel 4 to pass through is opened on the base plate 1, and the spiral blade 5 is rotatably arranged in the sampling barrel 4 through a rotating shaft. A first motor 6 is fixedly provided on the top of the top plate 3, and the output end of the first motor 6 is fixedly connected to the rotating shaft. A plurality of openings are equidistantly provided on the outer wall of the sampling barrel 4, and each opening is hingedly provided with a closing door 7. Each closing door 7 is provided with a locking assembly for locking it to the sampling barrel 4. The cleaning assembly is arranged on the top of the base plate 1, and the cleaning assembly is used to clean the outside of the sampling barrel 4. When the auger 3 is in the air, the auger 4 is moved upwards and the auger 4 is moved downwards, thereby the auger 3 is moved downwards and the auger 4 is moved downwards.

[0021] like Figure 2-3As shown, the rotating assembly further includes: an outer gear ring 8, which is fixedly mounted on the outer wall of the sampling barrel 4. A second motor 9 is fixedly mounted on the top of the top plate 3. The output end of the second motor 9 passes vertically downward through the top plate 3 and is provided with a gear 10. The gear 10 is engaged with the outer gear ring 8. When it is necessary to drive the sampling barrel 4 to rotate, the second motor 9 is started, and the second motor 9 drives the gear 10 to rotate. The gear 10 drives the outer gear ring 8 engaged therewith to rotate, thereby rotating the sampling barrel 4. Through the rotation of the sampling barrel 4 and the downward movement of the hydraulic rod 2, the sampling barrel 4 can be easily inserted into the deep part of the formation.

[0022] like Figure 1-2 As shown, each locking assembly further includes: a locking plate 11, which is fixedly connected to the free end of the closed door 7, and a threaded hole is formed on the locking plate 11. The outer wall of the sampling barrel 4 is provided with a plurality of receiving grooves corresponding to the locking plate 11, and the locking plate 11 is locked in the receiving groove by bolts. The opening on the sampling barrel 4 is connected to the interior of the sampling barrel 4. Specifically, the receiving groove is located on one side of the opening on the sampling barrel 4, so that after the closed door 7 rotates around its hinge, the locking plate 11 is located in the receiving groove. The closed door 7 and the sampling barrel 4 are locked by bolts passing through the threaded holes on the locking plate 11 to prevent the soil in the sampling barrel 4 from overflowing. When it is necessary to remove soil from different layers later, the closed door 7 is opened by releasing the bolts to facilitate the removal of soil from different strata.

[0023] like Figure 2-4 As shown, the cleaning assembly further includes: a fixed block 12, which is arranged on the top plate 3. The fixed block 12 is symmetrically and hingedly provided with a connecting plate 13 on one side facing the sampling barrel 4. Each connecting plate 13 is provided with a curved plate 14 on the end away from the fixed block 12. The opposite sides of the two curved plates 14 are provided with bristles. A driving member is also provided between the two connecting plates 13 to drive the two curved plates 14 to embrace the outer wall of the sampling barrel 4. When the sampling barrel 4 has completed collecting soil, the hydraulic rod 2 lifts the sampling barrel 4, and the rotating assembly drives the sampling barrel 4 to rotate again, so that the bristles on the two curved plates 14 rub against the outer wall of the sampling barrel 4, brushing the soil on the sampling barrel 4 clean, which is convenient for subsequent inspection personnel to open the closed door 7 to take out soil samples from different strata.

[0024] like Figure 3-4 As shown, the driving member is a spring 15, and the two ends of the spring 15 are fixedly connected to the opposite sides of the two connecting plates 13. By arranging the spring 15 between the two connecting plates 13, the spring 15 acts as a pull between the two connecting plates 13, allowing the two curved plates 14 to embrace the outer wall of the sampling barrel 4, so that the bristles on the curved plates 14 come into contact with the sampling barrel, thereby improving the cleaning effect.

[0025] like Figure 1-3As shown, further, both ends of the base plate 1 are rotatably provided with a rotating rod 16, and the outer wall of each rotating rod 16 is provided with a mounting tube 17, and the mounting tube 17 is slidably provided with an insertion rod 18. To make the device more stable during operation, after the device is moved to a predetermined position, the insertion rods 18 at both ends of the base plate 1 are inserted into the soil, so that the insertion rods 18 fix the device, reduce the shaking of the device during operation, and avoid safety problems caused by the device tilting or sliding, making it suitable for complex terrain.

[0026] Furthermore, the mounting tube 17 is rotatably connected to the rotating rod 16. For situations where the soil excavation area is complex and there are many rocks, the mounting tube 17 can be rotated to insert the insertion rod 18 into an area that is easy to insert. When the device is not in use, the mounting tube 17 can be rotated to make the insertion rod 18 horizontal, thereby not affecting the movement of the device.

[0027] like Figure 3 As shown, further, a plurality of crushing teeth 19 are provided at the bottom of the sampling tube 4. The crushing teeth 19 are provided at the bottom of the sampling tube 4 to facilitate the sampling tube 4 to more easily break the soil layer in the predetermined area when rotating, thereby improving the soil sampling efficiency.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
