Description

Technical Field

[0001] This utility model relates to the field of soil sampling equipment technology, and in particular to a soil stratification sampler. Background Technology

[0002] In agricultural production, environmental monitoring, and geological exploration, it is often necessary to perform stratified soil sampling. By analyzing the composition and structure of soil layers at different depths, data support is provided for subsequent research, planting planning, or environmental assessment. Currently, there are various soil sampling devices on the market. These devices typically need to penetrate into soil at different depths to obtain samples to meet the needs of stratified testing. Some devices are equipped with simple support structures and sampling components, but the overall design focuses more on basic sampling functions.

[0003] Existing soil sampling equipment suffers from significant instability when manually stabilized during actual use. The equipment is prone to rotation during sampling, increasing operational difficulty. Furthermore, samples tend to adhere to the inside of the sampling components after sampling, requiring additional tools for cleaning, which is cumbersome and not only affects sampling efficiency but may also damage the integrity of the sample during cleaning, causing inconvenience to subsequent testing. Therefore, a soil stratification sampler is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing manually stabilized devices, which have significant instability, and to propose a soil stratification sampler.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A soil stratification sampler includes a base plate, on the surface of which a plurality of vertically arranged guide rods are fixedly connected. A first slide plate and a second slide plate are slidably connected between the guide rods. A plurality of support mechanisms are provided between the first slide plate and the base plate for supporting the device. A sampling mechanism is provided at the bottom of the first slide plate for sampling.

[0007] The support mechanism includes a swing plate, which is rotatably connected to one side of the base plate. A support rod is rotatably connected between the swing plate and the first sliding plate. A support base is fixedly connected to one end of the bottom of the swing plate.

[0008] A positioning element, located on one side of one of the guide rods, is used to secure the first slide plate.

[0009] As a further embodiment of this utility model, the positioning component includes two insertion holes and a positioning pin. The two insertion holes are both opened on the circumference of one of the guide rods, and the positioning pin slides through one side of the first slide plate and passes through one of the insertion holes.

[0010] As a further improvement of this utility model, the bottom of each support base is fixedly connected with a conical positioning rod for inserting into the ground.

[0011] As a further embodiment of this utility model, the sampling mechanism includes a motor, which is fixed to the top of the first slide plate. One end of the motor output shaft passes through the first slide plate and is fitted with a connecting sleeve via a pin. An extension rod is threaded to the bottom of the connecting sleeve, and a sampling cylinder is threaded to the bottom of the extension rod.

[0012] As a further embodiment of this utility model, an installation port is provided on one side of the sampling cylinder, a baffle is provided inside the installation port, a connecting plate is welded to the top of the baffle, and a fixing bolt is threaded to the top of the connecting plate, the fixing bolt passing through the top of the sampling cylinder.

[0013] As a further improvement of this utility model, handrails are fixedly connected to both sides of the second skateboard.

[0014] As a further embodiment of this utility model, one of the guide rods has a through-type limiting rod inserted into one side for supporting the second slide plate after it is raised.

[0015] In this application, during use, the sampler is positioned at the sampling location. First, the positioning pin is removed, and then the first sliding plate is moved downwards. The first sliding plate pushes the swing plate to unfold via the support rod, and the sampler is supported by the support plate, improving the stability of use and preventing the sampler from rotating as a whole during sampling, thus reducing the difficulty of operation. Then, the sampling cylinder is connected to the extension rod, the extension rod is connected to the connecting sleeve, and the connecting sleeve is connected to the motor output shaft. During sampling, the limit rod is removed, the motor is started, and then the second sliding plate is moved downwards. The second sliding plate drives the sampling cylinder to move downwards for sampling. After sampling, the second sliding plate is lifted, and then the sampling cylinder and the fixing bolt can be removed, thereby allowing the baffle to be removed, which facilitates the removal of the sample, making operation convenient and preventing the sample from adhering to the inside of the sampling cylinder.

[0016] Beneficial effects: In this utility model, the soil stratification sampler, through the cooperation of the swing plate, support rod, support base with positioning rod and insertion hole and positioning pin, when the first slide plate is moved, the support rod will push the swing plate to unfold, the positioning rod at the bottom of the support base will be inserted into the ground, and then the positioning pin will be fixed through the insertion hole on the first slide plate and the guide rod. This can effectively prevent the whole device from rotating during sampling, improve the stability of use, eliminate the need for additional fixing operations, reduce the control difficulty for operators, and ensure that the sampling process is carried out smoothly.

[0017] In this utility model, a soil stratification sampler is used in conjunction with a connecting sleeve, an extension rod, a sampling tube, a baffle, and a fixing bolt. The extension rod can be replaced with one of different lengths according to the sampling depth. After sampling, the sampling tube can be removed, and the baffle can be removed by unscrewing the fixing bolt. The sample inside the tube can be easily taken out, avoiding the sample from adhering to the inner wall of the sampling tube. This eliminates the need for complicated tools, improves sampling efficiency, and ensures the integrity of the soil sample. Attached Figure Description

[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] In one embodiment: Refer to Figures 1-3 A soil stratification sampler includes: a base plate 1, with multiple vertical guide rods 2 fixedly connected to the surface of the base plate 1; a first sliding plate 3 and a second sliding plate 7 slidably connected between the guide rods 2; a through hole is provided in the middle of both the base plate 1 and the first sliding plate 3; and sliding holes matching the guide rods 2 are provided in both the first sliding plate 3 and the second sliding plate 7. The inner walls of the sliding holes are smoothed to ensure that the first sliding plate 3 and the second sliding plate 7 can slide smoothly up and down along the guide rods 2 without jamming. Multiple support mechanisms are provided between the first sliding plate 3 and the base plate 1 to support the entire device during use. A sampling mechanism is provided at the bottom of the first sliding plate 3 to penetrate the soil and complete the sampling operation; a positioning component is also provided on one side of one of the guide rods 2 to fix the position of the first sliding plate 3.

[0024] The support mechanism includes a swing plate 4, which is rotatably connected to one side of the base plate 1. A support rod 5 is rotatably connected between the swing plate 4 and the first slide plate 3. The two ends of the support rod 5 are respectively connected to corresponding positions on the swing plate 4 and the first slide plate 3, ensuring that the support rod 5 can move synchronously when the first slide plate 3 moves. A support base 6 is fixedly connected to one end of the bottom of the swing plate 4. The support base 6 is disc-shaped with a flat bottom, and a conical positioning rod is fixedly connected to the bottom of the support base 6. The positioning rod has moderate sharpness and can be inserted into the ground without causing safety hazards during operation due to excessive sharpness. When placing the sampler at the sampling position, first operate the positioning component to release the fixed state of the first slide plate 3, and then move the first slide plate 3 downward. During the movement of the first slide plate 3, the support rod 5 will push the swing plate 4 outward until the positioning rod at the bottom of the support base 6 is inserted into the ground. At this time, the sampler is supported by the swing plate 4 and the support base 6, which can greatly improve the stability of the equipment and prevent the sampler from rotating as a whole during sampling, reducing the difficulty of operation for the operator.

[0025] In another embodiment: Reference Figures 1-3 A soil stratification sampler.

[0026] The positioning component includes two insertion holes 10 and a positioning pin 11. Both insertion holes 10 are located on the circumferential surface of one of the guide rods 2, and are spaced apart along the axial direction of the guide rod 2. The spacing is determined by the required movement distance of the first slide plate 3 to allow the support mechanism to fully unfold, ensuring that when the first slide plate 3 is moved to a position where the support mechanism can be fully unfolded, one of the insertion holes 10 aligns with the pin hole on the first slide plate 3. The positioning pin 11 is a cylindrical structure with a smooth surface, and its diameter matches the diameter of the insertion hole 10 and the pin hole on the first slide plate 3. The positioning pin 11 slides through one side of the first slide plate 3 and through one of the insertion holes 10. When the first slide plate 3 needs to be moved, the positioning pin 11 is pulled out from the insertion hole 10 and the pin hole of the first slide plate 3, allowing the first slide plate 3 to slide up and down along the guide rod 2. After the first slide plate 3 moves to the appropriate position, the positioning pin 11 is reinserted into the corresponding insertion hole 10 and pin hole, thus fixing the first slide plate 3 and ensuring a stable support state for the support mechanism during operation.

[0027] The sampling mechanism includes a motor 9, which is bolted to the top of the first slide plate 3. The output shaft of the motor 9 is vertically downward, and one end of the output shaft passes through the first slide plate 3 and is fitted with a connecting sleeve 12 via a pin. The pin passes through the corresponding holes of the motor 9 output shaft and the connecting sleeve 12, ensuring that the connecting sleeve 12 can rotate synchronously with the motor 9 output shaft, and also facilitating subsequent disassembly and maintenance. The bottom of the connecting sleeve 12 has an internal thread, and the top of the extension rod 13 has an external thread. The bottom of the connecting sleeve 12 is threaded to the extension rod 13, and the bottom of the extension rod 13 also has an internal thread. The top of the sampling cylinder 14 has an external thread, and the bottom of the extension rod 13 is threaded to the sampling cylinder 14. This threaded connection method not only ensures a firm connection but also allows for the replacement of extension rods 13 of different lengths according to the required sampling depth, improving the applicability of the equipment. When preparing for sampling, tighten the sampling cylinder 14 and the extension rod 13 with threads, and then tighten the extension rod 13 and the connecting sleeve 12 with threads to ensure that the connection between the components is tight and that there will be no loosening or falling off during the sampling process. After that, check whether the pin connection between the connecting sleeve 12 and the output shaft of the motor 9 is firm to avoid relative rotation between the connecting sleeve 12 and the output shaft after the motor 9 starts.

[0028] The sampling tube 14 is a cylindrical structure with an installation port 15 on one side, wide enough to allow the baffle 16 to be inserted smoothly. The size of the baffle 16 matches the installation port 15, completely covering it to prevent soil leakage during sampling. A connecting plate 17 is welded to the top of the baffle 16. The connecting plate 17 is a sheet-like structure, perpendicular to the baffle 16, and has a threaded hole at its top. The fixing bolt 18 is a bolt structure that passes through the corresponding hole at the top of the sampling tube 14 and is threaded into the threaded hole of the connecting plate 17. Tightening the fixing bolt 18 will fix the baffle 16 inside the installation port 15. After sampling is completed, the sampling tube 14 is removed from the extension rod 13, and the fixing bolt 18 is unscrewed. Since the connecting plate 17 and the baffle 16 are welded together, the baffle 16 can be removed from the installation port 15 after the fixing bolt 18 is removed, so that the soil sample in the sampling tube 14 can be easily taken out. The operation process is simple and convenient, avoiding the situation where the sample adheres to the inner wall of the sampling tube 14 and is difficult to clean.

[0029] Handrails 8 are fixedly connected to both sides of the second slide plate 7. The handrails 8 are cylindrical rods covered with anti-slip rubber sleeves. A through-type limiting rod is inserted into one side of one of the guide rods 2. The limiting rod is a cylindrical metal rod with a diameter matching the diameter of the upper limit hole of the guide rod 2. The limiting rod can be easily inserted into or removed from the limiting hole. When the second slide plate 7 does not need to be moved, such as during the assembly of sampling components or the removal of samples, the second slide plate 7 is lifted upwards, and then the limiting rod is inserted into the limiting hole of the guide rod 2. The limiting rod will pass through from one side of the guide rod 2 to the other side. At this time, the bottom of the second slide plate 7 will contact the limiting rod, which can support the second slide plate 7 and prevent it from accidentally slipping, ensuring the safety of the operator and providing more operating space for the operator.

[0030] However, as is well known to those skilled in the art, the working principle and wiring method of motor 9 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0031] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0032] 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.
