Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology in water conservancy and soil science, specifically a portable combined soil sampling and sealing device for water conservancy and soil science. Background Technology

[0002] In the fields of water conservancy engineering, geological exploration and geotechnical engineering, obtaining representative undisturbed soil samples is the basis for conducting physical and mechanical property analysis and environmental assessment. Traditional soil sampling devices are mostly large fixed equipment or manual samplers, which have problems such as large size, inconvenience of carrying, low degree of automation and poor sampling efficiency. Especially when working in complex terrain or remote areas, it is difficult to meet the needs of rapid, accurate and multi-point sampling.

[0003] Existing portable sampling tools typically lack the ability to seal and classify samples on-site. Soil samples are easily affected by moisture, contamination, or structural disturbance during transportation, which can affect the accuracy of test results. In addition, most devices cannot quickly replace sampling components, resulting in frequent replacement of the entire machine under different geological conditions. This is cumbersome and costly. Therefore, we propose a portable modular soil sampling and sealing device for hydraulic and geotechnical engineering. Utility Model Content

[0004] The purpose of this utility model is to provide a portable combined hydraulic and soil sampling and sealing device to solve the problems mentioned in the background art, such as the lack of on-site sealing and classification storage functions of existing portable sampling tools, the susceptibility of soil samples to moisture, contamination or structural disturbance during transportation, which affects the accuracy of test results, and the inability of most devices to quickly replace sampling components, resulting in frequent replacement of the whole machine under different geological conditions, which is cumbersome and costly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable combined hydraulic and soil sampling sealing device, comprising: a portable sample body;

[0006] It also includes: a drive-to-replace sampling mechanism, which is mounted on the portable sampling body and is used to replace the drilling part and take soil samples.

[0007] The sample storage mechanism is installed on the portable sample collection device and is used to store soil samples.

[0008] The driving sampling mechanism includes a motor that is fixedly connected to the inside of the portable sample body. A gear is fixedly connected to the output end of the motor, and a limit internal gear disk meshes with the outer side of the gear.

[0009] The limiting inner toothed disc is rotatably connected to the inside of the portable sample retrieval body, and four connecting rods are fixedly connected to the bottom of the limiting inner toothed disc.

[0010] The bottom of each of the four connecting rods is fixedly connected to a positioning plate, and a sampling tube is installed at the bottom of the positioning plate.

[0011] The positioning plate and the sampling cylinder are both internally threaded with four bolts.

[0012] The sample storage mechanism includes multiple fixing rings that are equidistantly fixed to the outside of the portable sample retrieval body. The internal threads of the multiple fixing rings are connected to threaded caps, and the internal threads of the threaded caps are connected to storage containers.

[0013] The portable sample retrieval device is equipped with a controller, which is electrically connected to the motor.

[0014] This utility model has at least the following beneficial effects:

[0015] By setting up a drive-driven sampling mechanism, the installation and disassembly of the sampling cylinder can be made convenient through the structural cooperation between the positioning plate and the sampling cylinder connected by bolts. It also supports the use of multiple cylinders in rotation, thus providing users with options. Furthermore, the motor enables automatic drilling and sampling, reducing manual labor intensity and improving sampling efficiency. By setting up a sample storage mechanism, the storage container is fixed with a fixing ring and sealed with a threaded cap, which effectively prevents soil samples from getting damp, evaporating, or contaminated during transportation. It also allows for the separate preservation of various samples, thus ensuring the original state of the samples. Moreover, the whole system is integrated into a portable sampling body, which is small in size and light in weight, making it suitable for use in combination with the drive-driven sampling mechanism for easy portability.

[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. 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.

[0023] Example 1

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a portable combined hydraulic and soil sampling sealing device, comprising: a portable sample body 1;

[0025] It also includes: a drive to replace the sampling mechanism 2, which is installed on the portable sampling body 1 and is used to replace the drilling part and take soil samples.

[0026] The sample storage mechanism 3 is installed on the portable sample collection body 1 and is used to store soil samples.

[0027] The above-mentioned drive-change sampling mechanism 2 enables convenient assembly and disassembly by connecting the positioning plate 25 and the sampling cylinder 27 with bolts 26, and supports the use of multiple cylinders in rotation, thus providing users with options. The motor 21 enables automatic drilling and sampling, reducing manual labor intensity and improving sampling efficiency. The sample storage mechanism 3 fixes the storage tank 33 with a fixing ring 31 and seals it with a threaded cap 32, effectively preventing soil samples from getting damp, evaporating or contaminated during transportation, and distinguishing and storing various samples to ensure the original state of the samples. The whole system is integrated into the portable sample collection body 1, which is small in size and light in weight, and is suitable for portable combination with the drive-change sampling mechanism 2.

[0028] The driving sampling mechanism 2 includes a motor 21 fixedly connected to the inside of the portable sample body 1. A gear 22 is fixedly connected to the output end of the motor 21. A limiting internal gear 23 is meshed with the outer side of the gear 22. The limiting internal gear 23 is rotatably connected to the inside of the portable sample body 1. Four connecting rods 24 are fixedly connected to the bottom of the limiting internal gear 23. A positioning plate 25 is fixedly connected to the bottom of the four connecting rods 24. A sampling cylinder 27 is provided at the bottom of the positioning plate 25. Four bolts 26 are threadedly connected to the inside of both the positioning plate 25 and the sampling cylinder 27.

[0029] When in use, when the required sampling tube 27 needs to be replaced, the four bolts 26 can be rotated out, and then the positioning plate 25 can be separated from the sampling tube 27. Then, a new sampling tube 27 can be installed and placed correspondingly to the positioning plate 25. The positioning plate 25 can then be fixed to the sampling tube 27 using the four bolts 26. When drilling, the control motor 21 runs and rotates the gear 22, so that the rotating gear 22 drives the limiting inner gear plate 23 to rotate within the portable sample body 1. When the limiting inner gear plate 23 rotates, it can drive the positioning plate 25 to rotate through the connecting rod 24. Then, by utilizing the shape matching between the positioning plate 25 and the sampling tube 27, the sampling tube 27 can be rotated to take samples. Afterward, the rock samples are placed in different sample storage mechanisms 3.

[0030] Example 2

[0031] like Figures 2 to 5 In this second embodiment, the other structures remain unchanged, but the difference from the first embodiment is:

[0032] The sample storage mechanism 3 includes multiple fixing rings 31 that are fixedly connected at equal intervals to the outside of the portable sample retrieval body 1. The internal threads of the multiple fixing rings 31 are connected to threaded caps 32, and the internal threads of the threaded caps 32 are connected to storage containers 33.

[0033] When in use, when it is necessary to store the sample in the storage container 33, rotate the threaded cover 32 to separate the threaded cover 32 from the fixing ring 31, then take out the storage container 33 inside the threaded cover 32, then rotate the threaded cover 32 to separate it from the storage container 33, and then the sample can be stored in the storage container 33. After that, the storage container 33 can be placed in the portable sample retrieval body 1.

[0034] The portable sample retrieval body 1 is equipped with a controller 4, which is electrically connected to the motor 21;

[0035] When in use, when sampling is required, the handheld portable sampler 1 can operate the controller 4 to control the motor 21 to run, thereby enabling sampling.
