[0025] Please refer to Figures 1 to 7, the present utility model provides a technical solution: a sampling device for engineering investigation, including a sampling device main body 100. The sampling device main body 100 includes a bottom plate 101. One end of the upper surface of the bottom plate 101 is fixedly welded with a column 102. A lead screw 103 is rotated inside the column 102. The top end of the lead screw 103 is provided with a forward and reverse motor 104 on the upper surface of the column 102. After the sampling device main body 100 is stably placed by contacting the sampling position with the bottom end of the bottom plate 101, the driving motor 105 drives the sampling cylinder 106 to rotate, and the forward and reverse motor 104 drives the lead screw 103 to rotate. A moving plate seat 107 is arranged on the outer surface of the lead screw 103. A driving motor 105 is fixedly installed on the upper surface of the moving plate seat 107 by bolts. The end of the driving motor 105 is fixedly installed with a sampling cylinder 106 on the lower surface of the moving plate seat 107 by bolts. When the lead screw 103 rotates, the moving plate seat 107 moves on the outer surface of the lead screw 103. When the moving plate seat 107 moves, it drives the sampling cylinder 106 to move downward and rotate to perform underground sampling operation. After sampling, the sampling cylinder 106 is separated from the ground and the soil is taken out for investigation. The sampling device main body 100 is also provided with:

[0026] A self-lubricating mechanism, and the self-lubricating mechanism includes an oil storage component arranged on the upper surface of the end of the moving plate seat 107. A drainage and lubrication component is arranged at the edge of the inner bottom end of the oil storage component. When the sampling device main body 100 is in use, when the lead screw 103 rotates to drive the moving plate seat 107 to move, the moving plate seat 107 moves to drive the self-lubricating mechanism to move on the outer surface of the lead screw 103 for self-lubrication treatment, which is convenient for oil injection lubrication operation, smoothly drives the adjustment and sampling operation, and improves the convenience of self-lubrication treatment of the lead screw 103 during the engineering investigation and sampling operation of the sampling device main body 100.

[0027] In order to facilitate the storage of lubricating oil through the oil storage component for oil injection self-lubrication treatment, in this embodiment, preferably, the oil storage component includes a sleeve 1031 fixedly installed on the upper surface of the end of the moving plate seat 107 by screws. The lead screw 103 passes through the inside of the sleeve 1031. An oil storage groove 1033 is formed at the edge of the inside of the sleeve 1031. One end of the upper surface of the sleeve 1031 is provided with an oil injection port 1032. Lubricating oil is injected into the inside of the oil storage groove 1033 through the oil injection port 1032 and stored in an appropriate amount, which is convenient for storage and lubrication treatment.

[0028] In order to facilitate the lubrication treatment of the outer surface of the lead screw 103 through the drainage lubrication component and enable smooth rotation operation, in this embodiment, preferably, the drainage lubrication component includes a closed ring 1035 fixedly installed at the bottom edge inside the sleeve 1031 by screws. A drainage brush 1034 is arranged inside the closed ring 1035. The outer surface of the drainage brush 1034 extends into the oil storage tank 1033, and the inner surface of the drainage brush 1034 contacts the outer surface of the lead screw 103. When the lead screw 103 rotates to drive the moving plate seat 107 to move on the outer surface of the lead screw 103, at this time, the moving plate seat 107 drives the sleeve 1031 and the drainage brush 1034 to move, introducing lubricating oil into the drainage brush 1034 and then performing self-lubrication treatment by injecting oil onto the outer surface of the lead screw 103.

[0029] A mud scraping mechanism, and the mud scraping mechanism includes an installation component arranged at the bottom end of the column 102. A mud scraping component is arranged on the inner surface of the installation component. When the sampling device main body 100 finishes sampling in engineering exploration and the sampling cylinder 106 is separated from the soil, the mud scraping mechanism can scrape and clean the soil attached to the outer surface of the sampling cylinder 106, making the mud scraping and cleaning treatment more convenient and improving the convenience of cleaning the outer surface of the sampling cylinder 106 after the sampling device main body 100 finishes sampling in engineering exploration.

[0030] In order to facilitate the fixed installation of the scraping ring 1063 through the installation component and facilitate the installation of mud scraping treatment, in this embodiment, preferably, the installation component includes an installation ring 1061 fixedly installed at the inner bottom end of the column 102 by bolts, and the sampling cylinder 106 passes through the inside of the installation ring 1061, facilitating the fixed installation of the scraping ring 1063 through the installation ring 1061 for mud scraping and cleaning before use.

[0031] In order to facilitate the mud scraping and cleaning of the outer surface of the sampling cylinder 106 when it is separated from the soil after sampling through the mud scraping component, in this embodiment, preferably, the mud scraping component includes a fixed ring 1062 fixedly installed on the inner surface of the installation ring 1061 by screws. A scraping ring 1063 is integrally formed on the inner surface of the fixed ring 1062. The inner surface of the scraping ring 1063 contacts the outer surface of the sampling cylinder 106. When the sampling cylinder 106 is separated from the soil, the outer surface of the sampling cylinder 106 is in contact with the inner surface of the scraping ring 1063 inside the installation ring 1061 for scraping and cleaning, making the cleaning treatment convenient.

[0032] Working principle and usage process of the present utility model: For this kind of sampling device used in engineering investigation, during use, the bottom end of the bottom plate 101 contacts the sampling position and is stably placed. After the sampling device main body 100 is stably placed, the driving motor 105 drives the sampling cylinder 106 to rotate, and the forward and reverse motor 104 drives the lead screw 103 to rotate. When the lead screw 103 rotates, the moving plate seat 107 moves on the outer surface of the lead screw 103. When the moving plate seat 107 moves, it drives the sampling cylinder 106 to move downward and rotate to perform underground sampling operation. After sampling, the sampling cylinder 106 is removed from the ground for soil investigation use;

[0033] Then, when the sampling device main body 100 finishes sampling and the sampling cylinder 106 is detached from the ground, at this time, when the sampling cylinder 106 moves inside the mounting ring 1061, the outer surface of the sampling cylinder 106 contacts the inner surface of the scraping ring 1063 for scraping and cleaning treatment, which is convenient for quickly cleaning the outer surface of the sampling cylinder 106 after sampling. The mud scraping and cleaning treatment is more convenient, improving the convenience of cleaning the outer surface of the sampling cylinder 106 after engineering investigation sampling by the sampling device main body 100;

[0034] Finally, before the sampling device main body 100 is used, the drainage brush 1034 is fixed to the bottom end of the inner surface of the sleeve 1031 through the closing ring 1035, and lubricating oil is filled into the oil storage tank 1033 through the oil filling port 1032. After filling with oil, it is convenient to introduce the lubricating oil to the inner surface of the drainage brush 1034 through the drainage brush 1034. At this time, when the moving plate seat 107 moves on the outer surface of the bottom end of the lead screw 103, it drives the sleeve 1031 to move. When the sleeve 1031 moves, the inner surface of the drainage brush 1034 contacts the outer surface of the lead screw 103 for oil injection and self-lubrication treatment, which is convenient for always lubricating the lead screw 103 during the sampling operation. The lead screw 103 is exposed to the air and is not prone to rust, smoothly driving the adjustment and sampling operation, improving the convenience of self-lubrication treatment of the lead screw 103 during the engineering investigation sampling operation by the sampling device main body 100.
