Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil sampling technology, and in particular to a ring sampler that facilitates the preservation of soil morphology. Background Technology
[0002] A ring sampler is a sampling tool used for determining soil density and volume. It is mainly used for determining soil density and volume and is suitable for sampling needs in soil projects. The ring sampler body can be composed of a first semicircular ring sampler and a second semicircular ring sampler, which is convenient for maintaining soil morphology.
[0003] The prior art, as disclosed in Chinese Patent Publication No. CN220751665U, pertains to the field of soil sampling equipment technology, and specifically discloses a portable soil ring sampler. This sampler includes a main rod with a ring blade fixedly connected to its bottom end. The main rod has threads on its outer side, a discharge mechanism on its outer side, and a stabilizing mechanism fixedly connected to its outer side. The stabilizing mechanism includes a rectangular sleeve fixedly connected to the outer side of the main rod, and a mounting plate with a screw hole at its top. This portable soil ring sampler, through the stabilizing mechanism, limits the position of the mounting plate under the action of the base block, its conical block, and the threaded rod. A spirit level ensures the mounting plate is placed stably, and the rectangular hole and the rectangular sleeve in the mounting plate ensure that the pressure applied when pressing down on the ring blade with the handle is vertically downward, thus ensuring the accuracy of the soil sample data collected by the ring blade.
[0004] In actual operation, after the ring cutter samples the soil, the soil inside the ring cutter needs to be removed by rotating the threaded tube. Then, the threaded tube needs to be reversed to drive the round block to reset. This operation method affects the soil extraction efficiency. In addition, considering that the discharge mechanism is fixed inside the ring cutter, it is not convenient to disassemble and replace the ring cutter after long-term use. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as low soil sampling efficiency and inconvenience in disassembling and replacing the ring sampler, and to propose a ring sampler that facilitates the preservation of soil morphology.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design a ring sampler that facilitates the preservation of soil morphology, including a bracket, a support rod slidably connected to the top of the bracket, a sampler detachably connected to the free end of the support rod via a fixing structure, and a pushing structure located inside the sampler at the free end of the support rod, the sampler resetting and cooperating with the pushing structure to push out the internal soil.
[0008] Furthermore, the pushing structure includes a support frame and a push plate. The support frame is slidably connected to the periphery of the support rod. The top end of the support frame abuts against the bracket. The sampler is inserted through the bottom end of the support frame and the push plate is fixedly connected thereto. The push plate is slidably connected inside the sampler.
[0009] Furthermore, the sampler has an extension at the top midpoint, and the top opening of the extension extends toward the axis to form a snap-fit portion, and the sampler is arranged in half along the midpoint;
[0010] The extension is inserted into the outer periphery of the bottom end of the support rod, and the two halves of the snap-fit part close together and snap into the annular groove at the bottom of the support rod.
[0011] Furthermore, the two halves of the sampler are respectively provided with a docking part and a recessed part on opposite sides, and the docking part engages with the recessed part.
[0012] Furthermore, the fixing structure includes a connecting part and a fixing member. The connecting part is provided on the top of each half of the sampler on the opposite side, and the connecting parts on both sides are joined together to form a T-shaped structure.
[0013] The fastener avoids the connecting part by means of a relief groove, and the fastener is rotated half a revolution to make the relief groove and the connecting part misaligned.
[0014] Furthermore, the fastener is provided with positioning grooves on both sides of the relief groove, wherein the opposite sides of the connecting parts on both sides are provided with protruding structures, and the protruding structures are stopped in the positioning grooves by abutting and sliding.
[0015] The present invention proposes a ring sampler that facilitates the preservation of soil morphology. The advantages of this invention are as follows: the sampler can be directly driven to sample the soil by the support rod, and after sampling, the support rod can be pulled to reset the sampler. During the reset process, the soil inside the sampler can be directly pushed out by the push structure, which is convenient and quick.
[0016] After prolonged use, the fixing parts can be unlocked and disassembled by rotating them. The two samplers can be separated and disassembled when the fixing parts are no longer secured. The fixing parts and the connecting parts are locked in the positioning groove by a protruding structure, which further improves the stability of the connection between the two samplers.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figure 1-4 A ring sampler for facilitating soil morphology preservation includes a bracket 1, a support rod 2 slidably connected to the top of the bracket 1, a sampler 4 detachably connected to the free end of the support rod 2 via a fixing structure 3, and a pushing structure 5 located inside the sampler 4 at the free end of the support rod 2. The sampler 4 is reset and, in conjunction with the pushing structure 5, pushes out the soil inside.
[0024] Furthermore, the pushing structure 5 includes a support frame 51 and a push plate 52. The support frame 51 is slidably connected to the periphery of the support rod 2. The top end of the support frame 51 abuts against the bracket 1. The sampler 4 is inserted through the bottom end of the support frame 51 and the push plate 52 is fixedly connected thereto. The push plate 52 is slidably connected inside the sampler 4.
[0025] Furthermore, the sampler 4 has an extension 41 at the top midpoint, and the top opening of the extension 41 extends toward the axis to form a snap-fit part 42. The sampler 4 is arranged in half along the midpoint.
[0026] The extension 41 is inserted into the outer periphery of the bottom end of the support rod 2, and the two halves of the snap-fit part 42 are closed and snapped into the annular groove 21 at the bottom of the support rod 2.
[0027] In this embodiment, as Figure 2 As shown, the two halves of the sampler 4 are fastened to the periphery of the support rod 2 by the closing and fixing structure 3. In specific operation, the support rod 2 drives the sampler 4 to move down, and at the same time the sampler 4 drives the push plate 52 to move synchronously.
[0028] Among them, the push plate 52 is fitted with the inner wall of the sampler 4 with a gap, and it is necessary to eliminate the influence of the area of the push plate 52 inside the sampler 4 to ensure that the internal volume of the sampler 4 is appropriate without being affected by the push plate 52, so as to prevent errors in soil sampling.
[0029] Specifically, after the sampler 4 is filled with soil, the soil around the sampler 4 is cleared with a shovel or similar tool, and then the sampler 4 is removed. After clearing away the excess soil, the sampler 4 is reset by the support rod 2. Because the top of the support frame 51 is in contact with the bracket 1, the push plate 52 cannot continue to rise with the sampler 4, and the soil inside the sampler 4 can be pushed out by the push plate 52.
[0030] More specifically, the two halves of the sampler 4 are respectively provided with a docking part 43 and a recessed part 44 on opposite sides, and the docking part 43 and the recessed part 44 engage with each other.
[0031] It is worth mentioning that when the two halves of the sampler 4 are engaged with the docking part 43 and the recessed part 44, the stability of the two halves of the sampler 4 being closed and fixed can be further improved, and the influence of external force on the two halves of the sampler 4 when the fastener 32 is fixed can be reduced.
[0032] In general, the fixing structure 3 includes a connecting part 31 and a fixing member 32. The two halves of the sampler 4 are provided with the connecting part 31 on the top of opposite sides, and the two connecting parts 31 are closed to form a T-shaped structure.
[0033] The fixing member 32 avoids the connecting part 31 by means of the relief groove 33, and rotates the fixing member 32 half a turn so that the relief groove 33 and the connecting part 31 are misaligned.
[0034] Finally, the fixing member 32 is provided with positioning grooves 34 on both sides of the relief groove 33. The opposite sides of the connecting parts 31 on both sides are provided with protruding structures 35, which are stopped by sliding against the positioning grooves 34.
[0035] In this embodiment, after the fixing member 32 is rotated half a cycle, the two sides of the fixing member 32 rub against the protruding part of the connecting part 31 and the top wall of the sampler 4 respectively. Then, because the relief groove 33 and the connecting part 31 are arranged in a cross structure and misaligned, the two halves of the sampler 4 are closed and fixed.
[0036] The fastener 32 is preferably made of a material with deformation capabilities, such as rubber or plastic. Figure 4 As shown, the fastener 32 is also provided with deformation grooves on both sides corresponding to the positioning groove 34. When the protruding structure 35 abuts against the fastener 32, the fastener 32 deforms under the action of the deformation groove, causing the protruding structure 35 to be stuck in the positioning groove 34, reducing the movement of the fastener 32 during the sampling process.
[0037] Working method: During operation, the two halves of the sampler 4 are set around the support rod 2 and the push plate 52 by closing them together, and when they are closed, the snap-fit parts 42 on both sides are engaged in the annular groove 21.
[0038] The fastener 32 is engaged with the periphery of the two connecting parts 31 by the relief groove 33, and the relief groove 33 is misaligned with the protruding part of the connecting part 31 by half-circle rotation. During the rotation, the protruding structure 35 abuts against the fastener 32, and the fastener 32 deforms under the action of the deformation groove, so that the protruding structure 35 is locked in the positioning groove 34.
[0039] Finally, the sampler 4 is driven by the support rod 2 to perform sampling. After sampling is completed, the sampler 4 is driven to reset. At this time, because the support frame 51 is in contact with the bracket 1, the sampler 4 resets and, together with the push plate 52, pushes out the soil inside.
[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
