[0030] Example 1

[0031] Reference Figure 1-7 , which is the first embodiment of the utility model, provides a geotechnical engineering survey sampling device, which mainly includes:

[0032] Mobile assembly 100, such as Figure 1 The mobile assembly 100 includes a mobile base 101. Universal wheels 102 are fixedly installed at the four corners of the bottom of the mobile base 101 by bolts. The upper and lower sides of the mobile base 101 are provided with mutually connected avoidance grooves 103. The avoidance grooves 103 correspond to the sampling bucket 301, which facilitates the upward and downward movement of the sampling bucket 301 for sampling. A mobile handle 104 is fixedly installed on the top right side of the mobile base 101. Through the coordinated use of the mobile handle 104 and the universal wheel 102, the device can be conveniently pushed to the place of use for easy use.

[0033] Lifting assembly 200, such as Figure 2 The lifting assembly 200 is arranged corresponding to the avoidance groove 103. The lifting assembly 200 includes a gantry 201 fixedly connected to the upper surface of the mobile base 101 by bolts, a first cylinder 202 fixedly connected to the top of the gantry 201 by bolts, a lifting plate 203 fixedly connected to the bottom piston end of the first cylinder 202 by bolts, a pair of connecting rods 204 fixedly connected to the bottom of the lifting plate 203 and a second cylinder 205, a connecting plate 206 fixedly connected to the bottom end of the pair of connecting rods 204, and a blocking mechanism 207 fixedly connected to the bottom piston end of the second cylinder 205.

By setting the guide grooves 208, the lifting and lowering of the lifting plate 203 can be guided, so that the lifting plate 203 can be lifted and lowered smoothly;

[0034] The sampling assembly 300 is disposed at the bottom of the connecting plate 206 and is connected to the connecting plate 206 and the blocking mechanism 207;

[0035] A fixing assembly 400, which is connected to the sampling assembly 300 and the connecting rod 204, and is used to fix the sampling assembly 300 and the connecting plate 206 together;

[0036] The stabilizing component 500 is symmetrically arranged on the front and rear sides of the mobile base 101 and is fixedly connected to the mobile base 101 for fixing the device.

[0037] Specifically, the blocking mechanism 207 includes a vertical rod 207 - 1 fixedly connected to the piston end of the second cylinder 205 by bolts and a drill bit 207 - 2 fixedly connected to the bottom end of the vertical rod 207 - 1 .

[0038] Specifically, the sampling assembly 300 includes a sampling barrel 301 that is movably fitted with the bottom of the connecting plate 206 and a pair of first plug rods 302 that are fixedly connected to the top of the sampling barrel 301. The sampling barrel 301 is a barrel-shaped structure that is connected up and down. The drill bit 207-2 is adapted and slidably connected to the bottom opening of the sampling barrel 301. The vertical rod 207-1 is movably connected to the top of the sampling barrel 301 and the connecting plate 206. The upper and lower sides of the connecting plate 206 and the corresponding parts of the pair of first plug rods 302 are provided with first slots 209 that are connected up and down. The pair of first plug rods 302 are adapted and plugged into the pair of first slots 209 respectively. Through the adaptation and plugging of the first plug rods 302 and the first slots 209, the sampling barrel 301 can be quickly positioned and installed. The left and right sides of the pair of first plug rods 302 are provided with second slots 303, and the second slots 303 are located above the connecting plate 206. The fixing assembly 400 is arranged on the left side of the first plug rod 302 and is connected to the second slot 303.

[0039] Furthermore, the fixing assembly 400 includes a pair of second plug rods 401 respectively adapted to be plugged into a pair of second slots 303, a push-pull rod 402 fixedly connected to the front end of the pair of second plug rods 401, a pair of limit plates 403 movably fitted with the bottom of the push-pull rods 402, a pair of fixing plates 404 located above the push-pull rods 402, and a lifting rod 405 located above the pair of fixing plates 404, a pair of plug posts 406 are fixedly connected to the bottom of the lifting rod 405, a pair of plug posts 406 are respectively slidably passed through the pair of limit plates 403 and the pair of fixing plates 404, and the pair of plug posts 406 are both slidably passed through the push-pull rod 402, a spring 407 is fixedly connected between the top of the pair of fixing plates 404 and the lifting rod 405, and a pair of springs 407 are respectively movably sleeved on the plug posts 406 On the outside, the right sides of a pair of fixing plates 404 and a pair of limiting plates 403 are fixedly connected to the left sides of a pair of connecting rods 204 respectively, and the limiting plates 403, the fixing plates 404 and the upper and lower sides of the push-pull rod 402 are provided with insertion holes for the insertion posts 406 to slide through, wherein, by fixing the limiting plates 403 and the connecting rod 204 together, the push-pull rod 402 can be limited, thereby preventing the push-pull rod 402 from moving downward, thereby ensuring the stability of the first insertion rod 302 and improving the stability of the sampling barrel 301, and in addition, through the plug-in action of the insertion post 406, the push-pull rod 402 can be limited in the horizontal direction, so that the second insertion rod 401 fixedly connected to the push-pull rod 402 is not easy to fall out of the second slot 303, thereby further ensuring the stability of the sampling barrel 301.

[0040] In summary, when sampling, the lifting plate 203 is driven downward by the first cylinder 202, the lifting plate 203 drives the second cylinder 205 and the connecting rod 204 to move downward, the connecting rod 204 drives the connecting plate 206 to move downward, the connecting plate 206 drives the sampling barrel 301 to move downward, the second cylinder 205 drives the drill bit 207-2 to move downward through the vertical rod 207-1, and the tip of the bottom end of the drill bit 207-2 can penetrate into the soil, thereby facilitating the insertion of the sampling barrel 301 into the soil. After the sampling barrel 301 penetrates into the specified depth, the vertical rod 207-1 is driven downward by the second cylinder 205, the vertical rod 207-1 drives the drill bit 207-2 to move downward, the drill bit 207-2 is removed from the sampling barrel 301, and the bottom of the sampling barrel 301 is in an open state (such as Figure 6 ), close the second cylinder 205, and then use the first cylinder 202 to drive the sampling barrel 301 to move downward for sampling. After the sampling is completed, the second cylinder 205 drives the vertical rod 207-1 to move upward, and the vertical rod 207-1 drives the drill bit 207-2 to move upward, so that the drill bit 207-2 is re-sealed at the bottom opening of the sampling barrel 301 to prevent soil from falling when the sampling barrel 301 is rising.

[0041] When it is necessary to clean the inside of the sampling barrel 301, first, the lifting rod 405 is used to drive a pair of plug posts 406 to move upward at the same time, the spring 407 is stretched, and the pair of plug posts 406 are separated from the push-pull rod 402. After separation, the second plug post 401 is pulled by the push-pull rod 402 to move, so that the second plug post 401 is pulled out of the second slot 303, and the limit on the first plug post 302 is released. Then the sampling barrel 301 is moved downward, so that the first plug post 302 is disengaged from the first slot 209, and the disassembly is completed. The overall operation is simple, and no tools are required for disassembly and assembly, which is convenient for cleaning the sampling barrel 301.

[0044] The stabilizing component 500 includes an internal threaded tube 501, which is fixedly penetrated through the mobile base 101. A screw 502 is spirally penetrated inside the internal threaded tube 501. A rotating knob 503 is fixedly connected to the top of the screw 502, and a positioning cone 504 is fixedly connected to the bottom of the screw 502.

[0045] The remaining structures are the same as those of Example 1.

[0046] When fixing the device, the screw 502 is driven to rotate by rotating the knob 503, and the screw 502 moves downward along the internal threaded tube 501, and the screw 502 drives the positioning cone 504 to move downward, so that the positioning cone 504 is inserted into the soil to complete the fixation. The overall operation is simple, which can not only effectively fix the device, significantly improve the stability of the device, but also greatly facilitate the sampling operation and improve work efficiency.

[0047] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
