Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ring knife sample sampling, in particular to a ring knife sample sampling structure and a ring knife sample sampling device. Background Art
[0002] When evaluating the compaction quality of the structural layer at the construction site, it is necessary to test the density of fine-grained soil and inorganic binder-stabilized fine-grained soil structure with an age of no more than 2 days, and calculate the construction compaction degree. The "Highway Roadbed and Pavement Field Test Regulations" recommends using a ring cutter to test the compaction degree.
[0003] When using the ring knife method to test compaction, a manual soil sampler is usually used. When the manual soil sampler is used to test the density of clay soil and inorganic binder stabilized fine-grained soil, the ring knife needs to be driven into the compacted layer with the soil sampler's drop hammer. After reaching the sampling depth, the hammer and directional cylinder are removed, and the ring knife and the sample are dug out with a pickaxe. The operation steps are relatively cumbersome.
[0004] At present, most manual soil samplers cannot quickly and conveniently take out the ring knife samples, and there are still the following deficiencies in the test process:
[0005] 1. Before sampling, it is troublesome to assemble the equipment. When sampling, it is necessary to disassemble the equipment first, and then use a pickaxe to dig out the sample, which leads to low sampling efficiency;
[0006] 2. During the sampling process, it is difficult to control the ring knife to sample at a depth of 1 / 2 of the compacted layer thickness required by the operating specifications, making it difficult to accurately assess the construction compaction degree;
[0007] 3. When taking samples from deeper soil layers, since the heights of the ring cutter and the ring cover are fixed, after the drop hammer drives the ring cover flush with the ground, it cannot be driven in further, so the ring cutter cannot be sent to a deeper designated position. Utility Model Content
[0008] The technical problem to be solved by the utility model is: in view of the above existing problems, a ring knife sampling structure and a ring knife sample sampling device are provided.
[0009] The technical solution adopted by the utility model is: a ring knife sampling structure, characterized in that it includes:
[0010] Ring knife;
[0011] The sleeve is a two-piece split structure, and a ring knife groove for accommodating the ring knife is arranged inside the sleeve.
[0012] Through the above technical means, the sleeve has a two-petal split structure, and the two parts of the sleeve can cooperate with each other to form a stable structural form. This structural form is also convenient for assembly, disassembly and transportation. A ring knife groove is provided inside the sleeve, and a ring knife is placed in the ring knife groove. By pressing the sleeve into the test ground until the ring knife sampling in the sleeve is completed, and then pulling out the sleeve, the two-petal structure of the sleeve can be convenient for direct disassembly, and then the ring knife and the sample in the ring knife can be quickly taken out.
[0013] In some embodiments, a scale for observing the sampling depth is provided on the outer wall of the barrel of the sleeve.
[0014] In some embodiments, the 0 point of the scale corresponds to the middle position of the ring knife.
[0015] Through the above technical means, the depth of the ring cutter entering the test ground can be understood with the help of the scale on the outer wall of the sleeve, and the 0 point of the scale corresponds to the middle position of the ring cutter, so that when the ring cutter penetrates to the specified position, the middle of the ring cutter meets the requirement of the sample specification that it is at a depth of 1 / 2 of the compacted layer thickness.
[0016] In some embodiments, the first end of the sleeve is a connecting end, and the second end of the sleeve is a sampling end. The sampling end is provided with a serrated blade for easy pressing into the test ground.
[0017] Through the above technical means, the serrated blade is used to facilitate pressing the sleeve into the test ground when sampling.
[0018] In some embodiments, the sleeve is detachably connected to a sleeve spare segment.
[0019] Through the above-mentioned technical means, the spare segments of the sleeve can be flexibly assembled and adjusted according to actual needs, so that the ring cutter can penetrate into the specified position to meet the needs of the ring cutter for sampling deeper soil layers.
[0020] In some embodiments, the two halves of the sleeve are connected by magnetic attraction or snap-on connection.
[0021] In some embodiments, the sleeve is made of a material with high rigidity. If the sample ground is hard soil, stainless steel is used; if the sample ground is soft soil, hard plastic is used to prevent the sleeve from deforming during the sampling process.
[0022] Another technical solution adopted by the utility model is: a ring knife sample sampling device, characterized in that it includes:
[0023] The outer frame has openings at the top and bottom respectively corresponding to the positions;
[0024] An adjustment component, movably mounted at the top opening of the outer frame, and capable of moving along a perpendicular direction of the plane where the opening is located;
[0025] A ring knife sampling structure is connected to the end of the adjustment component facing the bottom opening of the outer frame, and the adjustment component, the ring knife sampling structure and the bottom opening of the outer frame are on the same axis;
[0026] The adjusting assembly can be used to control the ring knife sampling structure to move to the bottom opening of the outer frame, and then press it into the test ground to a specified depth.
[0027] In some embodiments, the outer frame includes a top plate, a column, and a bottom plate. The top plate and the bottom plate are each provided with a plurality of threaded holes. Both ends of the column are provided with external threads that cooperate with the threaded holes. The top plate and the bottom plate are connected via the column to form a frame. A first opening is provided on the top plate, and the adjustment component is movably connected in the first opening. A second opening is provided on the bottom plate, and the inner diameter of the second opening matches the outer diameter of the sleeve in the ring knife sampling structure.
[0028] In some embodiments, the adjustment assembly includes a handle, a threaded rod and a sleeve cover, the first end of the threaded rod is connected to the handle, the second end of the threaded rod is connected to the sleeve cover, the threaded rod is threadedly connected to the top opening of the outer frame, and the sleeve cover is used to detachably connect the ring knife sampling structure.
[0029] The beneficial effects of the utility model are:
[0030] 1. The sleeve is pressed into the test ground through the knife groove for placing the knife ring in the sleeve. The sleeve drives the knife ring to the soil layer of the specified depth and performs corresponding sampling. Then the sleeve is pulled out from the test ground. Since the sleeve adopts a two-petal split structure, the sleeve is convenient to assemble and disassemble. The two parts of the sleeve are connected by convenient methods such as magnetic attraction or snap fasteners, so that the pulled-out sleeve can be quickly disassembled, and the knife ring and the sample inside the knife ring can be directly taken out. Compared with using a pickaxe to dig out the knife ring and the sample, the sampling efficiency is greatly improved.
[0031] 2. There is a scale on the outer wall of the sleeve, which is used to observe the sampling depth of the ring cutter into the test ground; at the same time, the 0 point of the scale corresponds to the middle position of the ring cutter, which is beneficial for the ring cutter to be at a depth of 1 / 2 of the compacted layer thickness when sampling, thereby meeting the sample specifications and improving the accuracy of the construction compaction assessment.
[0032] 3. By equipping the sleeve with spare segments, the sleeve length can be flexibly adjusted according to actual construction needs, so that the ring cutter can be sent to the soil layer at a specified depth to meet the sampling needs of deeper soil layers. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model is further described below in conjunction with specific embodiments.
[0046] Embodiment 1:
[0047] Combination Figures 1 to 3As shown, this embodiment is a ring knife sampling structure, including a ring knife 1 and a sleeve 2, as shown in FIG. Figure 1 and Figure 2 As shown, the sleeve 2 is a two-petal split structure, and the two parts of the sleeve 2 are connected by magnetic attraction or snap connection to ensure that the sleeve 2 can be quickly assembled and disassembled, and then the sleeve 2 can be opened to take out the ring cutter 1 after the sampling is completed. The inner wall of the sleeve 2 is provided with a ring cutter groove 3 along the annular direction, and the ring cutter groove 3 is used to place the ring cutter 1. There is a scale on the outer wall of the barrel of the sleeve 2, and the 0 point of the scale corresponds to the middle position of the ring cutter 1. The scale is convenient for observing the sampling depth of the ring cutter 1 into the test ground. For example, when the soil layer depth is 30cm, it is necessary to sample at a depth of 15cm in the soil layer. Then, the sampling requirement can be achieved by driving the sleeve 2 to the outer scale of 15cm and stopping.
[0048] Furthermore, the first end of the sleeve 2 is a connection end, and the second end of the sleeve 2 is a sampling end. The sampling end of the sleeve 2 is provided with a serrated blade 5 for easy pressing into the test ground. Figure 3 As shown, the sleeve 2 is also equipped with a sleeve spare segment 4 with a scale and a buckle, and the sleeve 2 and the sleeve spare segment 4 are detachably connected, and the length of the sleeve 2 can be flexibly adjusted to facilitate the delivery of the ring cutter 1 to the specified position, thereby meeting the test requirements of deeper soil layers.
[0049] Furthermore, the material of the sleeve 2 needs to be a material with greater rigidity. If the soil on the test ground is hard soil, a material with greater rigidity, such as stainless steel, is required. For soft soil, a material with greater rigidity, such as hard plastic, can be used to prevent the sleeve 2 from being deformed during the sampling process.
[0050] Embodiment 2:
[0051] Combination Figures 4 to 7 As shown, this embodiment is a ring knife sample sampling device, including an outer frame 6, an adjustment component 11 and the ring knife sampling structure described in the above embodiment, the outer frame 6 includes a top plate 7, a column 8 and a bottom plate 9, a first opening is opened on the top plate 7, and a plurality of threaded holes 10 are also provided on the top plate 7, a second opening is opened on the bottom plate 9, and a plurality of threaded holes 10 are also provided on the bottom plate 9, both ends of the column 8 are formed with external threads matching the threaded holes 10, and the top plate 7 and the bottom plate 9 are connected through the column 8.

An adjustment component 11 is movably connected to the first opening of the top plate 7, and the adjustment component 11 can reciprocate along the vertical direction of the first opening at the first opening. The end of the adjustment component 11 facing the bottom opening of the outer frame 6 is connected to a ring knife sampling structure. Figure 5 and Figure 6 As shown, the inner diameter of the second opening of the bottom plate 9 matches the outer diameter of the sleeve 2 in the ring knife sampling structure.
[0053] Furthermore, the material of the outer frame 6 needs to be a material with greater rigidity. If the soil on the test ground is hard soil, a material with greater rigidity, such as stainless steel, is required. For soft soil, a material with greater rigidity, such as hard plastic, can be used to prevent the outer frame 6 from deforming during the sampling process.
[0054] In some embodiments, such as Figure 7 As shown, the adjustment assembly 11 includes a handle 12, a threaded rod 13 and a sleeve cover 14. The first end of the threaded rod 13 is fixedly connected to the handle 12, and the second end of the threaded rod 13 is fixedly connected to the sleeve cover 14. The inner circle of the first opening of the top plate 7 of the outer frame 6 is formed with an internal thread that matches the threaded rod 13, so that the threaded rod 13 can be threadedly connected to the first opening of the top plate 7. The sleeve cover 14 is used for detachably connecting the sleeve 2 in the ring knife sampling structure. Specifically, the sleeve cover 14 is connected to the first end of the sleeve 2 by a snap-on connection. In addition, it is ensured that the handle 12, the threaded rod 13, the sleeve cover 14 and the second opening of the bottom plate 9 are all on the same axis.
