Description

Technical Field

[0001] This utility model relates to the field of environmental sampling technology, and more specifically, to a rapid compaction device for soil sampling. Background Technology

[0002] Currently, during soil sample collection and transportation in my country, due to the inherent instability of the compounds and to save space occupied by loose samples, compaction or filling of soil samples is often necessary. For example, in GB / T32722-2016 "Guidelines for Long-Term and Short-Term Preservation of Soil Samples," section 11.3.5 stipulates that for volatile and semi-volatile organic compounds, "the container should be filled to minimize the top space, and low-temperature preservation should always be considered to reduce vapor pressure." Similarly, in HJ / T 166-2004 "Technical Specification for Soil Environmental Monitoring," section 7.3.3.3 requires that for the collection of samples for the detection of semi-volatile and non-volatile organic compounds, "the collected samples should be transferred to a clean, light-proof glass bottle, and the sample should fill the entire space as much as possible." Therefore, considering the validity of the samples, rapid compaction is necessary for preservation. However, manual operation is often required, as suitable compaction tools are unavailable. Furthermore, since the sample is soil, manual compaction with wooden shovels or similar tools is laborious, difficult to operate under pressure, and affects sampling efficiency.

[0003] Therefore, there is an urgent need to design a device that can be used to quickly compact and collect soil samples in various terrain environments, so that sampling personnel can quickly and conveniently collect soil samples in different locations, ensuring the validity of the samples and improving work efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a soil sampling and rapid compaction device, which has the advantage of rapid compaction.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid soil sampling and compaction device, comprising a base plate, a fixed frame fixedly connected to the top of the base plate, a transmission rod movably sleeved on the inner surface of the front of the fixed frame, a compaction handle fixedly connected to the front end of the transmission rod, a gear fixedly connected to the tail end of the transmission rod passing through the fixed frame and extending into the inner cavity of the fixed frame, and a lifting rod meshing with the outer surface of the gear, the top and bottom of the lifting rod both passing through the fixed frame and extending to the outer side of the fixed frame, a polytetrafluoroethylene gasket fixedly connected to the bottom end of the lifting rod, and a sampling bottle movably connected to the top of the base plate.

[0006] As a preferred embodiment of this utility model, an installation plate is fixedly connected to the outer surface of the transmission rod, a first baffle is fixedly connected to the outer surface of the installation plate, a second baffle is fixedly connected to the bottom of the inner cavity of the fixing frame, and a torsion spring is movably sleeved on the outer surface of the transmission rod, with the two ends of the torsion spring being movably connected to the outer surfaces of the first baffle and the second baffle, respectively.

[0007] As a preferred embodiment of this utility model, a rotating handle is movably sleeved on the inner surface of the top of the base plate, and the bottom end of the rotating handle penetrates the base plate and extends into the inner cavity of the base plate and is fixedly connected to a rotating rod.

[0008] As a preferred embodiment of this utility model, hollow rods are movably connected to both the front and rear sides of the outer surface of the rotating rod, and a rectangular plate is fixedly connected to the outer side of the hollow rods.

[0009] As a preferred technical solution of this utility model, a C-shaped rod is fixedly connected to the left side of the rectangular plate, and the other end of the C-shaped rod passes through the bottom plate and extends to the outside of the bottom plate and is fixedly connected to an arc-shaped clamping plate. The inner side of the arc-shaped clamping plate is movably connected to the outer surface of the sampling bottle.

[0010] As a preferred embodiment of this utility model, a spring is fixedly connected to the outer surface of the rectangular plate, and the other end of the spring is fixedly connected to the inner surface of the base plate.

[0011] As a preferred embodiment of this utility model, the number of the arc-shaped clamps is two, the two arc-shaped clamps are the same size, and the two arc-shaped clamps are symmetrical about the center of the polytetrafluoroethylene gasket.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up a compaction handle, transmission rod, gear, lifting rod, and polytetrafluoroethylene (PTFE) gasket, allows the operator to rotate the compaction handle, which in turn drives the transmission rod and gear to rotate around the central axis of the transmission rod. This causes the lifting rod to move the PTFE gasket vertically downward under the limiting action of the fixed frame. As the PTFE gasket continues to move downward, the soil sample in the sampling bottle is compacted, significantly improving sampling efficiency and ease of operation. Furthermore, the inert gasket effectively prevents cross-contamination and volatilization of the sample, ensuring the accuracy and standardization of subsequent soil sample analysis.

[0013] 2. This utility model, by setting up a rotating rod, a hollow rod, a rectangular plate, a C-shaped rod, and an arc-shaped clamping plate, rotates the rotating handle, which drives the rotating rod to rotate synchronously. At this time, the rotation of the rotating rod will squeeze the two hollow rods and the rectangular plate, so that the hollow rod and the rectangular plate drive the C-shaped rod to move horizontally under the limiting action of the base plate, overcoming the elastic force of the spring. This causes the two arc-shaped clamping plates to move horizontally in opposite directions, releasing the fixing effect on the sampling bottle, and completing the functions of quick positioning and disassembly of the sampling bottle. This prevents the sampling bottle from shaking during the compaction process, which could cause the sample to escape. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 7As shown, this utility model provides a rapid soil sampling and compaction device, including a base plate 1, a fixed frame 2 fixedly connected to the top of the base plate 1, a transmission rod 4 movably sleeved on the inner surface of the front of the fixed frame 2, a compaction handle 3 fixedly connected to the front end of the transmission rod 4, a gear 5 fixedly connected to the tail end of the transmission rod 4 through the fixed frame 2 and extending into the inner cavity of the fixed frame 2, and a lifting rod 6 meshing with the outer surface of the gear 5, the top and bottom of the lifting rod 6 both through the fixed frame 2 and extending to the outer side of the fixed frame 2, a polytetrafluoroethylene gasket 7 fixedly connected to the bottom end of the lifting rod 6, and a sampling bottle 8 movably connected to the top of the base plate 1.

[0018] When the operator rotates the compaction handle 3, it will drive the transmission rod 4 and gear 5 to rotate around the central axis of the transmission rod 4. This will cause the lifting rod 6 to drive the polytetrafluoroethylene gasket 7 to move vertically downward under the limiting action of the fixed frame 2. Finally, as the polytetrafluoroethylene gasket 7 continues to move downward, the soil sample in the sampling bottle 8 will be compacted.

[0019] Among them, the outer surface of the transmission rod 4 is fixedly connected to the mounting plate 9, the outer surface of the mounting plate 9 is fixedly connected to the first baffle 10, the bottom of the inner cavity of the fixing frame 2 is fixedly connected to the second baffle 12, and the outer surface of the transmission rod 4 is movably sleeved with a torsion spring 11, the two ends of the torsion spring 11 are movably connected to the outer surfaces of the first baffle 10 and the second baffle 12 respectively.

[0020] When the compaction handle 3 is rotated, the mounting plate 9 and the first baffle 10 will rotate together. At this time, the first baffle 10 will rotate and squeeze the torsion spring 11. When the compaction handle 3 is released, the compaction handle 3 can quickly return to its original position due to the elastic force of the torsion spring 11, so as to facilitate subsequent compaction.

[0021] The bottom of the base plate 1 is movably fitted with a rotating handle 13 on the inner surface of the top. The bottom end of the rotating handle 13 passes through the base plate 1 and extends into the inner cavity of the base plate 1, and is fixedly connected with a rotating rod 14.

[0022] When the rotary handle 13 is rotated, the rotating rod 14 will rotate synchronously.

[0023] Hollow rods 15 are movably connected to both the front and rear sides of the outer surface of the rotating rod 14, and rectangular plates 16 are fixedly connected to the outer side of the hollow rods 15.

[0024] The rotation of the rotating rod 14 will compress the two hollow rods 15, causing the two hollow rods 15 to drive the two rectangular plates 16 to move horizontally in opposite directions.

[0025] A C-shaped rod 17 is fixedly connected to the left side of the rectangular plate 16. The other end of the C-shaped rod 17 passes through the base plate 1 and extends to the outside of the base plate 1, and is fixedly connected to an arc-shaped clamp 18. The inner side of the arc-shaped clamp 18 is movably connected to the outer surface of the sampling bottle 8.

[0026] When the rotating rod 14 is rotated, the hollow rod 15, the rectangular plate 16, and the C-shaped rod 17 will move horizontally under the limiting action of the base plate 1.

[0027] A spring 19 is fixedly connected to the outer surface of the rectangular plate 16, and the other end of the spring 19 is fixedly connected to the inner surface of the base plate 1.

[0028] Due to the elastic force of spring 19, rectangular plate 16 and C-shaped rod 17 have a good reset effect during subsequent movement.

[0029] There are two arc-shaped clamps 18, the two arc-shaped clamps 18 are the same size, and the two arc-shaped clamps 18 are symmetrical about the polytetrafluoroethylene gasket 7.

[0030] By moving the two symmetrical sampling bottles 8 in opposite directions, the sampling bottles 8 can be fixed directly below the polytetrafluoroethylene gasket 7, thus avoiding errors caused by manual positioning.

[0031] Working principle and usage process of this utility model: First, rotate the handle 13, which will drive the rotating rod 14 to rotate synchronously. At this time, the rotation of the rotating rod 14 will squeeze the two hollow rods 15 and the rectangular plate 16, so that the hollow rods 15 and the rectangular plate 16 drive the C-shaped rod 17 to move horizontally under the limiting action of the base plate 1 and overcome the elastic force of the spring 19. This causes the two arc-shaped clamps 18 to move horizontally in opposite directions. Then, the sampling bottle 8 containing the soil sample is placed under the polytetrafluoroethylene gasket 7. Then, release the handle 13. At this time, due to the elastic force of the four springs 19, the two arc-shaped clamps 18 will quickly reset, thus fixing the sampling bottle 8. This completes the quick positioning and disassembly function of the sampling bottle 8, preventing the sampling bottle 8 from shaking during the compaction process and causing the sample to escape.

[0032] Then, rotating the compaction handle 3 causes the transmission rod 4 and gear 5 to rotate around the central axis of the transmission rod 4. This causes the lifting rod 6 to move the polytetrafluoroethylene gasket 7 vertically downward under the limiting action of the fixed frame 2. Finally, as the polytetrafluoroethylene gasket 7 continues to move downward, the soil sample in the sampling bottle 8 is compacted, which significantly improves the sampling efficiency and ease of operation. The inert gasket also effectively prevents cross-contamination and volatilization of the sample, ensuring the accuracy and standardization of the subsequent analysis process of the soil sample.
