Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to an automatic soil surface sample point sampling device. Background Technique

[0002] After determining the sampling points within the electronic fence for collecting the surface soil mixed samples, the multi-point mixing methods such as the plum blossom method, the checkerboard method or the serpentine method are used for sampling. However, the existing soil sample point sampling equipment has some deficiencies, such as:

[0003] A soil sampler capable of automatically storing soil samples with the application number of CN202010287606.3 can automatically re-align the position of the disc and lift the disc to ensure that the soil sample can accurately fall into the storage tank. However, in the actual use process, the sampled soil will be broken, thus mixing the soil layers. During the sampling process, the levels of the soil samples may be disrupted, thereby reducing the accuracy of detection during sampling;

[0004] Therefore, we propose an automatic soil surface sample point sampling device to solve the problems raised above. Content of the Utility Model

[0005] The purpose of the utility model is to provide an automatic soil surface sample point sampling device to solve the problem that most of the current soil surface sample point sampling equipment on the market will break the sampled soil, thus mixing the soil layers. During the sampling process, the levels of the soil samples may be disrupted, thereby reducing the accuracy of detection during sampling as mentioned in the above background technique.

Subsequently, the hydraulic rod drives equipment such as the sampling cylinder 13 to descend. The external blade and the auger shaft blade rotate driven by the sampling cylinder, enabling better sampling work. Moreover, when the soil sample enters the interior of the sampling cylinder, it can maintain the original layer within the soil sample point, ensuring that the equipment does not damage the sample itself during sampling.

[0039] The device main body 1 is connected to the driving mechanism. The driving mechanism includes a first sprocket 3, and the first sprocket 3 is connected to the driving motor 2. A chain 4 is engaged with the outside of the first sprocket 3. A second sprocket 5 is engaged with the front end of the chain 4. A first rotating shaft 6 is connected to the left end of the first sprocket 3. A first bevel gear 7 is connected to the outside of the first rotating shaft 6. A second bevel gear 8 is engaged with the bottom of the first bevel gear 7. The bottom of the second bevel gear 8 is fixedly connected to the driving shaft 9;

[0040] A second rotating shaft 16 is connected to the left end of the second sprocket 5. A third bevel gear 17 is provided outside the second rotating shaft 16. A fourth bevel gear 18 is engaged with the bottom of the third bevel gear 17. The fourth bevel gear 18 is connected to the fixing mechanism; a ratchet group is provided at the left end of the first sprocket 3, and a ratchet group is also provided at the left end of the second sprocket 5. The ratchets of the ratchet groups provided at the left ends of the first sprocket 3 and the second sprocket 5 face in opposite directions; the fixing mechanism includes a bidirectional threaded shaft 19, and the top of the bidirectional threaded shaft 19 is fixedly connected to the fourth bevel gear 18. A threaded cylinder 20 is provided outside the bidirectional threaded shaft 19. The threaded cylinder 20 is slidably connected to the bottom of the device main body 1.

[0041] A bearing seat is provided inside the device main body 1. The device main body 1 is slidably connected to the driving shaft 9 through the bearing seat; two groups of sliding grooves are provided inside the driving shaft 9, and two groups of sliding blocks are provided inside the connecting shaft 10.

The device main body 1 is slidably connected to the fourth bevel gear 18 through the bearing seat;

[0042] Embodiment 2:

[0043] Another driving mechanism is disclosed in this embodiment, which is different from the first embodiment. Specifically, as Figure 6 shown, the difference between this embodiment and the first embodiment is that the first sprocket 3 is connected to the first rotating shaft 6 through a ratchet assembly, and the second sprocket 5 is connected to the second rotating shaft 16 through a ratchet assembly. The ratchet assembly includes a first ratchet 22, and the left end of the first ratchet 22 meshes with a second ratchet 23. The left end of the second ratchet 23 is connected to a spring shaft 24;

[0044] When the driving motor 2 rotates forward, the ratchet assembly at the left end of the first sprocket 3 will engage, that is, the first ratchet 22 meshes with the second ratchet 23. The second ratchet 23 drives the first rotating shaft 6 to rotate through the spring shaft 24. When the driving motor 2 rotates in the reverse direction, the ratchet assembly at the left end of the first sprocket 3 will disengage, that is, the first ratchet 22 disengages from the second ratchet 23, and the second ratchet 23 retracts under the drive of the spring shaft 24, so that the first rotating shaft 6 stops rotating; and since the ratchet assemblies at the left ends of the first sprocket 3 and the second sprocket 5 face in opposite directions, when the ratchet assembly at the left end of the first sprocket 3 disengages, the ratchet assembly at the left end of the second sprocket 5 will engage, so that the second sprocket 5 drives the second rotating shaft 16 to rotate through the ratchet assembly;

[0045] Embodiment 3:

[0046] Another sampling cylinder mechanism is disclosed in this embodiment, which is different from the first embodiment. The difference between this embodiment and the first embodiment is that the sampling cylinder 13 includes two semi-cylindrical cylinders, and the semi-cylindrical cylinders are connected to each other through a snap member. A cavity is provided inside the sampling cylinder 13 for placing soil samples. An arc-shaped protective aluminum sheet is provided inside the sampling cylinder 13 to prevent the sampling cylinder 13 from being eroded by soil during sampling. When disassembling the sampling cylinder 13, only the two semi-cylindrical cylinders need to be disassembled.

[0047] Working principle: When using the automatic sampling device for soil surface sampling points, first connect the device power supply to the power grid for power supply. Subsequently, start the drive motor 2, so that the drive motor 2 drives the first sprocket 3 provided inside the drive mechanism to rotate. Thereby, the first sprocket 3 drives the second sprocket 5 to rotate through the chain 4, so that the first sprocket 3 drives the first rotating shaft 6 and the first bevel gear 7 to rotate. And the first bevel gear 7 will drive the second bevel gear 8 and the drive shaft 9 provided inside the sampling mechanism to rotate, so that the drive shaft 9 rotates inside the connecting shaft 10. Thereby, the drive shaft 9 drives the connecting shaft 10 and the sampling cylinder 13 to rotate. At the same time, start the hydraulic rod 11, so that the hydraulic rod 11 pushes the connecting shaft 10 and the sampling cylinder 13 to descend. And at this time, the external blade 15 at the bottom of the sampling cylinder 13 will cut the sample point soil, so that the sample point soil is cut into a circle and enters the sampling cylinder 13 after passing through the auger shaft blade 14. Subsequently, stop the drive motor 2, and start the hydraulic rod 11 again to raise the sampling cylinder 13. And because the auger shaft blade 14 stops rotating, it will block the bottom of the sampling cylinder 13, thereby sealing the bottom of the sampling cylinder 13.

[0048] When the sampling cylinder 13 is descending, the second sprocket 5 will also drive the second rotating shaft 16 and the third bevel gear 17 to rotate, so that the third bevel gear 17 drives the fourth bevel gear 18 and the bidirectional threaded shaft 19 provided inside the fixing mechanism to rotate. Thereby, the bidirectional threaded shaft 19 drives the threaded cylinder 20 to rise and fall, so that the threaded cylinder 20 drives the fixed drill bit 21 to rise and fall, so that the fixed drill bit 21 is connected to the soil inside, thereby fixing the device main body 1, making the device more stable during sampling.

[0049] Thus, a series of work is completed. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0050] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
