Description

Technical Field

[0001] This utility model relates to the field of ring cutters, specifically a testing device that can be used in water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of mitigating harm and promoting benefits. They include dike projects, water supply projects, and irrigation projects. Among them, dike projects are water-retaining structures built along the banks of rivers, lakes, and oceans to resist floods and protect the safety of the coastal areas.

[0003] To ensure the quality of dike construction, it is necessary to test the dike structure during the construction process. For example, the soil of the dike body can be obtained by using the ring cutter method, and the soil sample can be processed to obtain the dry density of the soil, thereby obtaining the compaction degree of the dike body soil and judging the quality of dike filling.

[0004] When using the ring cutter method to collect soil samples from the embankment, clear away debris around the sampling point, scrape off a certain thickness of the topsoil (usually 5-10cm), then insert the ring cutter into the soil layer by hammering or other means. Subsequently, use tools such as shovels to clear the soil around the ring cutter, so that the ring cutter is fully exposed. Finally, use a shovel to separate the soil at the bottom of the ring cutter, thus completing the soil sampling.

[0005] While the above operations can separate the soil layer from the soil inside the ring sampler, cleaning the soil around the ring sampler to fully expose it takes a long time, which is not conducive to efficient soil sampling. In addition, when cleaning the soil around the ring sampler, improper operation can easily cause the ring sampler to move, affecting the accuracy of sampling.

[0006] To address the aforementioned issues, new ring cutter devices have emerged in the market. For example, a Chinese patent with publication number CN105181379B discloses a ring cutter soil sampler. This sampler includes a ring cutter, a ring cutter fixing sleeve, and a handle structure. The ring cutter includes a cutter holder and at least two blades, which are positioned at one end of the cutter holder and arranged concentrically. The cutter holder is fixedly connected to the ring cutter fixing sleeve, and the handle structure is fixedly connected to or integrally formed with the ring cutter fixing sleeve. The blade shape is similar to a Luoyang shovel, making soil entry easier. Rotating the handle structure allows the sampled columnar soil to be separated vertically from the surrounding soil. Then, shaking the handle structure left and right separates the sampled columnar soil from the surrounding soil horizontally. Finally, lifting the sampler allows the soil to be removed without the need for auxiliary tools to excavate the ring cutter, thus preventing damage to the surrounding soil environment.

[0007] The patent disclosed above describes a method for separating the soil layer from the soil inside the ring cutter by shaking the handle left and right, forcing the soil column inside the ring cutter to move with it, thereby separating the soil layer below the ring cutter. Common sense tells us that while this operation achieves soil separation, it is highly likely that some soil from inside the ring cutter will remain on the soil layer during the separation process, leading to sampling errors and affecting the test results. Utility Model Content

[0008] The purpose of this invention is to provide a testing device that can be used in water conservancy projects, aiming to improve the problem that it is inconvenient to separate soil samples and soil layers when taking soil samples with a ring cutter, or that separating soil samples and soil layers can easily cause sampling deviations.

[0033] 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 part; they can refer to a mechanical connection or an electrical connection; 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: Example 1

[0035] like Figure 1-5 As shown, to facilitate the separation of soil samples and soil layers while minimizing the impact on the soil sample, this embodiment provides a new ring cutter 1 with a cutting wire 3 at its top. When using the ring cutter 1 to extract soil samples, the cutting wire 3 is inserted into the soil layer synchronously with the ring cutter 1. However, the cutting wire 3 is located on the outside of the ring cutter 1, thus not affecting the quality of soil entering the ring cutter 1. After the ring cutter 1 extends to the corresponding depth in the soil layer, controlling the movement of the end of the cutting wire 3 protruding from the ring cutter 1 allows the cutting wire 3 buried in the soil to separate the soil sample and soil layer, changing the current practice of removing soil from the periphery of the ring cutter 1 and shaking the ring cutter 1 left and right to achieve the separation of soil sample and soil layer.

[0036] Specifically, a bottom ring plate 2 is installed below the cutter head 1. The inner space of the bottom ring plate 2 is divided into a columnar structure and a frustum structure, with the columnar structure located above the frustum structure. The top diameter of the frustum space of the bottom ring plate 2 is equal to the diameter of the columnar space and smaller than the bottom diameter of the frustum space. In this structure, the sidewall of the columnar space of the bottom ring plate 2 and the inner sidewall of the cutter head 1 are located on the same curved surface, and the outer sidewall of the bottom ring plate 2 and the outer sidewall of the cutter head 1 are also located on the same curved surface. When the cutter head 1 is inserted into the soil layer under the action of external force, the bottom ring plate 2 is inserted into the soil layer first.

[0037] To prevent the cutting wire 3 from interfering with soil entry into the ring cutter 1, a second receiving groove 21 is provided at the top of the conical space of the bottom ring plate 2. Simultaneously, a notch 22 is provided on the side wall of the conical space, communicating with the second receiving groove 21. Therefore, after the cutting wire 3 is laid in an arc shape in the second receiving groove 21, with its end extending outward through the notch 22, it carries the cutting wire 3 into the soil when the ring cutter 1 is inserted into the soil layer, facilitating the pulling of the cutting wire 3 to cut the soil sample and soil layer. In actual operation, a longer cutting wire 3 can be placed in the second receiving groove 21 to reduce or even eliminate the influence of friction on the state of the cutting wire 3 when the ring cutter 1 is inserted into the soil layer. Meanwhile, a first receiving groove 11 is provided on the outer side of the ring cutter 1, with the cutting wire 3 laid in the first receiving groove 11 through the notch 22. In actual operation, materials (such as devices adapted to the first receiving groove 11) can be filled into the first receiving groove 11 so that the device moves synchronously with the ring knife 1 and controls the slitting wire 3 to be placed stably, which can further reduce or even eliminate the influence of friction on the state of the slitting wire 3.

[0038] In order to detachably mount the bottom ring plate 2 below the ring cutter 1, an external threaded tube 12 is fixedly mounted on the bottom of the ring cutter 1, and a first internal threaded tube 23 is mounted on the top of the bottom ring plate 2. The first internal threaded tube 23 is threaded onto the external threaded tube 12, thereby realizing the detachable connection between the ring cutter 1 and the bottom ring plate 2. Example 2

[0039] like Figure 6-10As shown, based on Example 1, to facilitate control of the end movement of the slitting wire 3 and achieve the slitting of soil samples and soil layers, a first annular top plate 4 is provided above the ring cutter 1. Two annular locking grooves 43 are distributed vertically on the outer side of the first annular top plate 4. At the same time, two first pulling plates 41 are distributed vertically on the outer side of the first annular top plate 4. Each of the two first pulling plates 41 has a locking plate 45 fixedly installed on its side. The locking plate 45 is located in the locking groove 43. Therefore, the first pulling plate 41 is movably disposed on the side of the first annular top plate 4, that is, it can rotate around an axis under the action of external force. In addition, the two first pulling plates 41 are respectively connected to both ends of the slitting wire 3. Therefore, when the first pulling plate 41 rotates, it drives the end of the slitting wire 3 to move, thereby realizing the slitting of soil samples and soil layers.

[0040] In order to facilitate the disassembly of the first pull plate 41, an inlet / outlet groove 44 is provided at the buckle groove 43. The size of the inlet / outlet groove 44 is larger than the size of the buckle plate 45. Therefore, the buckle plate 45 can be installed in the buckle groove 43 through the inlet / outlet groove 44.

[0041] In order to stably connect the first annular top plate 4 with the ring cutter 1, an external threaded tube 12 is also provided on the top of the ring cutter 1, and a second internal threaded tube 42 is fixedly provided below the first annular top plate 4. The second internal threaded tube 42 is threaded onto the external threaded tube 12. Example 3

[0042] like Figure 11 , Figure 12 As shown, based on Example 1, in order to facilitate the control of the end movement of the cutting wire 3 and realize the cutting of soil samples and soil layers, a second annular top plate 5 is provided above the ring cutter 1. Two second pulling plates 51 are symmetrically arranged on the outer side of the second annular top plate 5. One end of the second pulling plate 51 is hinged to the second annular top plate 5, and the other end is connected to the cutting wire 3. At the same time, a driving plate 53 is fixedly provided on the side of the second pulling plate 51. Therefore, when the operator holds the driving plate 53 to control the second pulling plate 51 to rotate around the axis, the cutting wire 3 is forced to move during the rotation until the cutting wire 3 is separated from the soil sample and soil layer.

[0043] In order to stably connect the second annular top plate 5 with the ring cutter 1, an external threaded tube 12 is also provided on the top of the ring cutter 1. At the same time, a second annular top plate 5 is provided above the ring cutter 1, and a second internal threaded tube 42 is fixedly provided below the second annular top plate 5. The second internal threaded tube 42 is threaded onto the external threaded tube 12.

[0044] 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.
