Description

Technical Field

[0001] The present application relates to the technical field of geotechnical exploration, and particularly to a geotechnical high-slope exploration device. Background Art

[0002] In engineering construction and the natural environment, the stability of geotechnical high slopes is an important factor affecting engineering safety, environmental protection, and economic investment. Therefore, during the exploration process, it is necessary to take samples of the underground soil of high slopes for testing to analyze the substance content in the soil, which is a crucial link for the preliminary geological exploration of such projects.

[0003] When taking soil samples, a soil sampler is often used. The existing soil samplers are usually long tubular. After the soil sampling operation is completed, soil samples are likely to remain inside. Moreover, due to the long and thin tube of the soil sampler, it is rather troublesome to clean the remaining soil samples inside. Utility Model Content

[0004] In order to facilitate the cleaning of the remaining soil samples, the present application provides a geotechnical high-slope exploration device.

[0005] The present application provides a geotechnical high-slope exploration device, adopting the following technical solution:

The sampling tube is hollow. The cleaning component includes a mounting ring connected to the rotating ring and two cleaning plates fixedly connected to the mounting ring. Both cleaning plates are arc-shaped and respectively fit against the inner walls on both sides of the sampling tube. The drill bit penetrates through and is fixedly connected to the lower end face of the mounting ring at its upper end. The drill bit, the mounting ring, and the rotating ring are all communicated with the inner cavity of the sampling tube.

[0007] Optionally, a plurality of strip-shaped holes are formed in the side wall of the cleaning plate.

[0008] Optionally, scraping plates with inclined side edges are respectively fixedly connected to both side edges of the cleaning plate, and the side edges of the scraping plates abut against the inner wall of the sampling tube.

[0009] Optionally, the side edge of the scraping plate is serrated.

[0010] Optionally, an annular groove is formed in the circumferential direction of the end face of the sampling tube, and an annular block is slidably connected in the annular groove. The protruding end of the annular block is fixedly connected to the end face of the rotating ring.

[0011] Optionally, a plurality of connecting rods are fixedly connected to the end face of the mounting ring. The plurality of connecting rods are arranged and distributed circumferentially along the mounting ring. A plurality of connecting grooves for the connecting rods to pass through are formed in the end face of the rotating ring. A locking assembly for locking the connecting rods is arranged in the connecting grooves, and the locking assembly is clamped to the connecting rods.

[0012] Optionally, a receiving groove is formed in the inner wall of the connecting groove. The locking assembly includes a spring and a locking block. One end of the spring is fixedly connected to the bottom of the receiving groove, and the other end of the spring is fixedly connected to the locking block. A locking groove for the locking block to be clamped is formed in the connecting rod.

[0013] Optionally, the lower end opening of the drill bit is inclined.

Detailed Description of the Embodiment

[0021] The following is a further detailed description of the present application with reference to the attached Figures 1-4 to further illustrate the present application.

[0022] The embodiment of the present application discloses a geotechnical high slope exploration device.

[0023] Referring to Figure 1 and Figure 2 , the geotechnical high - slope exploration device includes a sampling tube 1, a rotating ring 2 rotatably connected to the end face of the sampling tube 1, and a drill bit 3 respectively connected to the rotating ring 2. The rotating ring 2 is provided with a cleaning component 4. The sampling tube 1 is hollow. The cleaning component 4 includes a mounting ring 41 detachably connected to the rotating ring 2 and two cleaning plates 42 fixedly connected to the end face of the mounting ring 41. Both cleaning plates 42 are arc - shaped, and the two cleaning plates 42 are located on both sides of the axis of the mounting ring 41. The cleaning plates 42 are located in the inner cavity of the sampling tube 1 and are in contact with the inner wall of the sampling tube 1. A plurality of strip - shaped holes 43 are formed in the side wall of the cleaning plate 42. Scrapers 44 are respectively welded to both side edges of the cleaning plate 42. The side edge of the scraper 44 facing away from the cleaning plate 42 is inclined, and the inclined side edge of the scraper 44 abuts against the inner wall of the sampling tube 1. At the same time, the side of the scraper 44 is serrated. The drill bit 3 is provided with a through - opening, and the lower opening of the drill bit 3 is inclined. The upper end of the drill bit 3 is welded to the lower end face of the mounting ring 41. The drill bit 3, the mounting ring 41, and the rotating ring 2 are all coaxial with the sampling tube 1 and the inner cavities are communicated.

[0024] Referring to Figure 2 and Figure 3 , a circumferential annular groove 11 with a T - shaped cross - section is formed in the end face of the sampling tube 1 along its circumference. A ring - shaped block 12 is slidably connected in the annular groove 11. The ring - shaped block 12 includes a circular plate and a vertical rod fixedly connected to the circular plate. Among them, the circular plate is located in the annular groove 11, and the vertical rod extends out of the annular groove 11 and is fixedly connected to the end face of the rotating ring 2. At the same time, in order to prevent soil from entering the annular groove 11 and affecting the sliding of the ring - shaped block 12, a sealing strip can be arranged between the two side edges of the annular groove 11 and the vertical rod of the ring - shaped block 12.

[0025] Referring to Figure 3 and Figure 4 , in order to make it more convenient for the operator to take out the soil in the sampling tube 1, a plurality of connecting rods 5 are fixedly connected to the end face of the mounting ring 41. The plurality of connecting rods 5 are arranged and distributed circumferentially along the mounting ring 41. A plurality of connecting grooves 6 for the connecting rods 5 to pass through are formed in the end face of the rotating ring 2. A locking component 7 is arranged in the connecting groove 6. A receiving groove 8 is formed in the inner wall of the connecting groove 6. The locking component 7 includes a spring 71 and a locking block 72. One end of the spring 71 is fixedly connected to the bottom of the receiving groove 8, and the other end of the spring 71 is fixedly connected to the locking block 72. The connecting rod 5 is provided with a locking groove 73 for the locking block 72 to be clamped. The two side edges of the locking block 72 are inclined.

[0026] Thus, when the sampling is completed, a pulling force can be applied to the mounting ring 41, and the connecting rod 5 applies a force to the locking block 72, causing the locking block 72 to compress the spring 71, so that the locking block 72 is separated from the locking groove 73, and then the mounting ring 41 is separated from the rotating ring 2, so that the cleaning plate 42 can be pulled out. When the cleaning plate 42 is pulled out, the soil can be taken out together. After that, the cleaning plate 42 can be inserted into the sampling tube 1 again, and the cleaning plate 42 is rotated to make the scraping plate 44 scrape the residual soil on the inner wall of the sampling tube 1.

[0027] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
