Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, and in particular to an integrated device for soil sampling and storage in geological exploration. Background Technology

[0002] Soil sampling is a common geological survey method used in infrastructure construction, agricultural soil surveys, mineral exploration, and environmental monitoring. Currently, powered soil samplers are one of the most common methods for soil sampling. Powered soil samplers typically have a sampling tube with an inner cavity at the bottom, and a ring cutter is installed at the bottom of the sampling tube. By moving the sampling tube down through the soil layer to be sampled, the soil sample enters the sampling tube, and then the sampling tube is pulled out to the ground to obtain the soil sample.

[0003] Among them, a common soil sampling tube is the electric soil sampler disclosed in application number 201720256509.1. The side of the ring cutter (i.e., the soil sampling tube) is provided with a long and narrow groove. After the ring cutter lifts the soil sample to the ground, the soil sample is observed and taken out from the long and narrow groove.

[0004] The prior art disclosed in the aforementioned patents is prone to damaging the shape of the soil sample and the distribution of the soil layers when the soil sample is removed from the ring cutter. This makes the soil sample mostly suitable only for on-site observation and testing, and it is difficult to preserve and transport the soil sample in its state within the soil layer.

[0005] Therefore, there is an urgent need to improve the existing soil sampling equipment. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides an integrated device for soil sampling and storage in geological exploration. It enables the collection and storage of soil samples through an inner cylinder, facilitates the removal of the inner cylinder through a support shell, and protects the inner cylinder during the removal process, effectively solving the problems existing in the prior art.

[0008] Furthermore, the cross-sectional profile of the semi-shell is semi-arc-shaped.

[0009] Furthermore, the support shell includes a first elastic hoop, which can be clamped on the outside of the two semi-shells to fix the beam semi-shells.

[0010] Furthermore, a first mounting groove is formed on the outer side of the semi-shell, and the first elastic hoop is disposed in the first mounting groove.

[0011] Furthermore, the semi-shell is bent inward to form the first mounting groove.

[0012] Furthermore, the semi-shell is provided with a plurality of first mounting grooves at intervals along its axial direction, and the inner surface of the semi-shell forms a second mounting groove at two adjacent first mounting groove positions; the integrated device also includes a second elastic hoop, which can be sleeved on the outside of the inner cylinder and is disposed in the second mounting groove.

[0013] Furthermore, the first elastic hoop abuts against the inner surface of the soil sampling cylinder.

[0014] Furthermore, the first elastic hoop is configured as a rubber elastic hoop.

[0015] Furthermore, the second elastic hoop is configured as a rubber elastic hoop.

[0016] Furthermore, the top of the semi-shell is provided with a baffle, and the top of the soil sampling cylinder is provided with an outlet hole.

[0023] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0024] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0025] Furthermore, it should be understood in the description of this utility model that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0028] In this utility model, such as Figure 1-3As shown, a soil sampling and storage device for geological exploration is provided, comprising: a soil sampling cylinder 1, one end of which forms an open soil sampling port and the other end forms a connecting end, wherein an annular soil sampling knife 2 is provided at the soil sampling port; a support shell 3, comprising two detachable half-shells 301, wherein the support shell 3 can be fitted into the soil sampling cylinder 1; and an inner cylinder 4, wherein the inner cylinder 4 is a transparent inner cylinder 4, and the inner cylinder 4 can be inserted into the support shell 3, wherein the inner cylinder 4 is open toward the soil sampling port.

[0029] In use, the integrated soil sampling and storage device of this utility model assembles two half-shells 301 on the outside of the inner cylinder 4, and then places the support shell 3 inside the soil sampling cylinder 1, thus completing the assembly of the soil sampling cylinder 1, the support shell 3, and the inner cylinder 4. Soil sampling is then performed, during which the soil sample enters the inner cylinder 4. After sampling is completed, the soil sampling cylinder 1 is raised to the ground. At this point, the support shell 3 can be removed from the soil sampling cylinder 1, and after disassembling the support shell 3, the transparent inner cylinder 4 can be removed. Workers can then directly observe the morphology and soil layer distribution of the soil sample inside the inner cylinder 4 through the transparent inner cylinder 4. Workers can choose to open the inner cylinder 4 on-site for further observation and testing of the soil sample, or they can maintain the original shape of the soil sample through the inner cylinder 4 for preservation and transportation to other locations for further observation and testing.

[0030] Because this application uses separate support shell 3 and inner cylinder 4, a plastic inner cylinder 4 with high transparency and resistance to damage can be selected, and a support shell 3 made of metal or high-hardness plastic can be used. This reduces the manufacturing cost and cutting difficulty of consumables (inner cylinder 4) (some testing activities require cutting open the inner cylinder 4 to remove soil samples). The support shell 3 also provides protective support for the inner cylinder 4, facilitating the application of force to the support shell 3 when removing the inner cylinder 4 from the soil sampling cylinder 1, preventing deformation of the inner cylinder 4 caused by the applied force during removal and thus preventing changes in the soil sample's shape. Furthermore, when the soil sample is squeezed into the inner cylinder 4 and an outward force is applied to it, the support shell 3 constrains the inner cylinder 4 during removal, preventing deformation of the inner cylinder 4 after the loss of external constraint outside the soil sampling cylinder 1 or changes in shape after the release of internal soil pressure.

[0031] Preferably, regarding the structure of this utility model, as shown in the figure, the cross-sectional profile of the semi-shell 301 is semi-arc-shaped.

[0032] Regarding the disassembly and assembly structure of the support shell 3, in a preferred embodiment, as shown in the figure, the support shell 3 includes a first elastic hoop 5. The first elastic hoop 5 can be clamped on the outside of the two half-shells 301 to fix the half-shells 301. As shown in the figure, this allows the support shell 3 to be fixed to the outside of the inner cylinder 4 by the first elastic hoop 5 after the half-shells 301 are assembled on the outside of the inner cylinder 4.

[0033] To improve the fixing effect of the first elastic hoop 5 on the support shell 3, a preferred further optimization is that a first mounting groove 6 is formed on the outer side of the semi-shell 301, and the first elastic hoop 5 is clamped in the first mounting groove 6. By setting the first mounting groove 6, the first elastic hoop 5 can be positioned and installed during installation, and when the support shell 3 is placed into or removed from the soil sampling cylinder 1, the first elastic hoop 5 can be prevented from sliding relative to the support shell 3, thereby achieving the effect of stably fixing the support shell 3.

[0034] Preferably, and more specifically, the semi-shell 301 is bent inward to form the first mounting groove 6.

[0035] As shown in the figure, the half-shell 301 is bent to form the first mounting groove 6, which facilitates the processing of the half-shell 301.

[0036] In the illustrated embodiment, for the structure of the semi-shell 301, more specifically, as shown in the figure, the semi-shell 301 has a plurality of first mounting grooves 6 spaced apart along its axial direction, and the inner surface of the semi-shell 301 forms a second mounting groove 7 at two adjacent first mounting grooves 6; the integrated device also includes a second elastic band 8, which can be sleeved on the outside of the inner cylinder 4, and the second elastic band 8 is disposed in the second mounting groove 7.

[0037] As shown in the figure, after the half shell 301 is bent at intervals to form the first mounting groove 6, the second elastic hoop 8 is set in the second mounting groove 7. The friction between the second elastic hoop 8 and the support shell 3, and the friction between the second elastic hoop 8 and the inner cylinder 4 can be used to increase the stability of the connection between the inner cylinder 4 and the support shell 3, so as to prevent the inner cylinder 4 from falling off relative to the support shell 3.

[0038] In a preferred embodiment, a further optimization of this invention is that the first elastic hoop 5 abuts against the inner surface of the soil sampling cylinder 1. As shown in the figure, the friction between the support shell 3 and the soil sampling cylinder 1 is increased by the first elastic hoop 5, so as to prevent the support shell 3 from slipping out of the soil sampling cylinder 1 due to relative movement between the support shell 3 and the soil sampling cylinder 1 during the process of the soil sampling cylinder 1 moving downward to collect soil and being lifted to the ground.

[0039] In terms of the structural configuration of this utility model, as a preferred embodiment, the first elastic hoop 5 is configured as a rubber elastic hoop.

[0040] In terms of the structural configuration of this utility model, as a preferred embodiment, the second elastic hoop 8 is configured as a rubber elastic hoop.

[0041] In the illustrated embodiment, regarding the method of removing the support shell 3 from the soil sampling cylinder 1, specifically as shown in the figure, a baffle 302 is provided at the top of the semi-shell, and an ejection hole 9 is provided at the top of the soil sampling cylinder 1. As shown in the figure, when it is necessary to remove the support shell 3 from the soil sampling cylinder 1, a push rod can be inserted into the soil sampling cylinder 1 through the ejection hole 9 to push the support shell 3 out of the soil sampling cylinder 1.

[0042] It should be noted that the improvement of this utility model focuses on the structure of the soil sampling cylinder, and does not restrict the improvement of the connection between the soil sampling cylinder and the power soil sampler. As one example, more specifically, in the embodiment shown in the figure, the top of the soil sampling cylinder is provided with a threaded connecting post, which can be directly connected to the drive rod of the power soil sampler.

[0043] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0044] The above description is merely an embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the scope of the claims of this application.
