Description

Technical Field

[0001] This utility model relates to the technical field of sampling devices, and more specifically, to a sampling device for soil testing. Background Technology

[0002] Soil testing is a comprehensive assessment of the various physical, chemical, and biological properties of soil, aiming to understand its fertility, pollution level, and suitable crop types. Soil testing is of great significance in agriculture, environmental protection, land development, and pollution control.

[0003] Soil testing typically requires soil sampling, usually using sampling tubes to preserve the samples. In practice, staff need to carry a large number of sampling tubes to the sampling site, collect multiple samples from various locations, and then bring the samples back to the testing laboratory for analysis. Since a large number of samples are needed to accurately determine the soil condition, a correspondingly large number of sampling tubes are required. The back-and-forth transfer of sampling tubes is a significant workload for staff and also impacts testing efficiency. Therefore, a device that can more efficiently preserve and transfer sample tubes could be designed. Utility Model Content

Detailed Implementation

[0024] Example

[0025] The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 - Appendix Figure 7 As shown, the soil testing sampling device of this embodiment includes a housing 11, a plurality of horizontally arranged storage components 20 within the housing 11, and a gripping component 30; the storage component 20 includes a horizontally arranged storage plate 21 and a plurality of fixing rings 22 disposed on the storage plate 21; a sampling tube 23 is clamped in a fixing ring 22; the gripping component 30 includes a hollow gripping plate 31, a plurality of through holes 32 opened on the gripping plate 31, and a limiting device 40 disposed inside the gripping plate 31; the arrangement of the plurality of through holes 32 is the same as the arrangement of the plurality of fixing rings 22. Specifically, during use, the sampling tube 23 is placed in the fixing ring 22 on the placement plate 21. Upon arrival at the sampling site, the sampling tube 23 is removed for on-site sampling. After sampling, the sampling tube 23 is placed back into the fixing ring 22. After all samples have been collected, the box 11 is transported back to the testing center for testing. At this time, the gripping plate 31 can be placed above the placement plate 21, the through hole 32 aligned with the sampling tube 23, and then the gripping plate 31 is moved downwards to insert the sampling tube 23 into the through hole 32. Then, the limiting device 4 is used to... The sampling tube 23 is fixed in place, and then all the sampling tubes 23 on a shelf 21 can be removed at once. The gripping component 30 can not only remove the sampling tubes 23 from the shelf 21, but also transfer the sampling tubes 23 in batches and place the sampling tubes 23 on the shelf 21. This can be done very efficiently to pick up and transfer the sampling tubes 23. For large batches of samples, it can not only effectively reduce the labor intensity of the operator, but also effectively improve the detection efficiency.

[0026] The limiting device 40 in this embodiment includes multiple clamping plates 41, connecting pieces 42 for connecting adjacent clamping plates 41, connecting rods 43 for connecting adjacent connecting pieces 42, elastic members connected to the connecting rods 43, and pull rods 44 connected to the connecting rods 43; one clamping plate 41 is located on the side of a through hole 32, one side of the gripping plate 31 is an open side, and the pull rod 44 passes through the open side of the gripping plate 31 and is located outside the gripping plate 31. Specifically, the operating principle of the limiting device 40 is as follows: Before the sampling tube 23 enters the through hole 32, the pull rod 44 is manually pulled. The pull rod 44 sequentially pulls the connecting rod 43, the connecting piece 42, and the clamping plate 41, preventing the clamping plate 41 from coinciding with the through hole 32. Then, the gripping plate 31 is lowered, allowing the sampling tube 23 to enter the through hole 32. The pull rod 44 is then released. At this time, the elastic element pulls the connecting rod 43, the connecting piece 42, and the clamping plate 41, causing the clamping plate 41 to enter the through hole 32 and contact the side wall of the sampling tube 23. The sampling tube 23 is clamped by the action of the clamping plate 41 and the inner wall of the through hole 32, allowing the sampling tube 23 to be transferred. It should be noted that a strip-shaped groove 34 can be provided on the inner wall of the gripping plate 31, and a strip-shaped sliding strip can be provided on the connecting rod 43, allowing the sliding strip to slide in the groove 34. This ensures the linearity and stability of the clamping plate 41 and other structures during movement.

[0027] In this embodiment, the clamping plate 41 is arc-shaped, and the center of the clamping plate 41 is located in the through hole 32. Specifically, the arc-shaped clamping plate 41 can increase the contact area between the clamping plate 41 and the sampling tube 23, and increase the clamping force of the clamping plate 41 on the sampling tube 23.

[0028] In this embodiment, a rubber pad is provided on the side of the clamping plate 41 near the through hole 32, and a rubber pad is also provided on the inner wall of the through hole 32. Specifically, the rubber pad can effectively increase the clamping stability of the sampling tube 23 by the clamping plate 41 and the through hole 32.

[0029] In this embodiment, the connecting piece 42 is an elastic metal sheet. Specifically, when the clamping plate 41 holds the sampling tube 23, each connecting piece 42 will undergo corresponding deformation, so that each clamping plate 41 can stably hold the sampling tube 23, and the movement of the clamping plates 41 will not be affected by each other.

[0030] In this embodiment, the elastic element is a spring. One end of the spring is connected to the connecting rod 43, and the other end is fixedly connected to the inner wall of the gripping plate 31.

[0031] In this embodiment, the gripping plate 31 is provided with a handle 33 on the side near the pull rod 44; the handle 33 is parallel to the pull rod 44. Specifically, the handle 33 is provided to facilitate the operator's gripping.

[0032] In this embodiment, the housing 11 is provided with a vertically arranged partition 12, and multiple storage components 20 are provided on both sides of the partition 12; the multiple storage components 20 are evenly distributed along the vertical direction. Specifically, this can effectively increase the number of storage components 20 in the housing 11, thereby increasing the number of sampling tubes 23 that can be accommodated.

[0033] In this embodiment, the box body 11 has doors 13 on both opposite sides.

[0034] In this embodiment, the upper end of the box 11 is provided with a handle 14.

[0035] In summary, the soil testing sampling device of this embodiment involves placing the sampling tube 23 in the fixing ring 22 on the placement plate 21 during use. Upon arrival at the sampling site, the sampling tube 23 is removed for on-site sampling. After sampling, the sampling tube 23 is returned to the fixing ring 22. After all samples have been collected, the box 11 is transported back to the testing center for testing. At this time, the gripping plate 31 can be placed above the placement plate 21, the through hole 32 aligned with the sampling tube 23, and then the gripping plate 31 is moved downwards to allow the sampling tube 23 to engage with the through hole 32. The sampling tube 23 is fixed by the limiting device 40, and then all the sampling tubes 23 on a shelf 21 can be removed at once. The gripping component 30 can not only remove the sampling tubes 23 from the shelf 21, but also be used for batch transfer of sampling tubes 23 and placing sampling tubes 23 on the shelf 21. This can be done very efficiently to pick up and transfer the sampling tubes 23. For cases with a large number of samples, it can not only effectively reduce the labor intensity of the operator, but also effectively improve the detection efficiency.

[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
