[0002] Geotechnical engineering, a branch of civil engineering, primarily studies the mechanical properties, stability, and applications of foundations, soils, and rocks in engineering construction. Sampling in geotechnical engineering involves collecting underground soil, rocks, and other geological materials for laboratory analysis to assess their engineering properties and suitability. Due to terrain and environmental factors, portable sampling equipment is often used. However, most existing portable sampling equipment requires disassembly and assembly, necessitating transport to a designated location before reassembly. Although portable, the equipment still requires sufficient stability and robustness; some individual components remain quite heavy after disassembly, necessitating multiple people to move them. The bulky nature of the components and the need for specialized tools for transport further complicate on-site operations. Utility Model Content

[0023] 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.

[0024] Please see Figure 1 , 2As shown in Figures 3, 4, 5, and 6, this utility model provides a technical solution: a survey and sampling device, comprising: a support platform 10 with a through hole in the middle; a sampling component placed on top of the support platform 10, the sampling component including a lifting platform 13 with lifting and lowering, a water spray nozzle installed at the bottom of the lifting platform 13 corresponding to the sampling cylinder 15, the water spray nozzle being connected to an external water pump via a water pipe, a gasoline engine 14 fixedly connected to the top of the lifting platform 13, the sampling cylinder 15 being detachably installed at the output end of the gasoline engine 14, a chain transmission assembly 20 for driving the lifting platform 13 to rise and fall above the support platform 10; a support frame 1 rotatably mounted on one end of the top of the support platform 10, adjustable movable wheels 3 installed on the outside of the support platform 10, the movable wheels 3 being adjusted to be perpendicular to the ground when transporting the sampling component, and the movable wheels 3 being adjusted to be parallel to the ground when the sampling component is sampling, and a receiving box 5 installed in the middle of the support frame 1 for storing samples.

[0025] It should be noted that, in this embodiment, during the transportation of the sampling device, the moving wheel 3 is fixed at an angle perpendicular to the ground, and the vertical slide bar 12 is locked to the support frame 1. This allows the support frame 1 to be pulled forward by the moving wheel 3 contacting the ground. After being pulled to the designated position, the support frame 1 is rotated to a position parallel to the ground. Stones or other counterweights are placed on top of the support frame 1, and then the moving wheel 3 is rotated to the side of the support frame 1 to level it. The sampling cylinder 15 is rotated by the gasoline engine 14, and the lifting platform 13 is moved downward by the chain drive assembly 20. The lifting platform 13 causes the sampling cylinder 15 to contact the ground and extend downward, thus enabling sampling from the ground. The sample inside the sampling cylinder 15 is then placed in the receiving box 5.

[0026] In one embodiment, two vertical slide rods 12 are fixedly connected to the top of the support platform 10. The lifting platform 13 is slidably connected to the vertical slide rods 12 through a sleeve. A connecting plate 17 is fixedly connected to one side of the lifting platform 13. A protective box 16 is fixedly connected to the top of the support platform 10. A groove that mates with the connecting plate 17 is provided on one side of the protective box 16. A chain drive assembly 20 is rotatably installed inside the protective box 16. The chain drive assembly 20 includes two sprockets that are rotatably installed at both ends of the vertical slide rods 12. A chain is installed between the two sprockets. The chain is fixedly connected to the connecting plate 17. A handwheel 19 is rotatably connected to one side of the protective box 16. The middle part of the handwheel 19 is connected to the chain drive assembly 20 through a chain drive assembly 28.

[0027] It should be noted that in this embodiment, the chain drive assembly 18 includes a fixed plate. Two drive sprockets are rotatably connected to one side of the fixed plate. The two drive sprockets are connected by a drive chain. One drive sprocket is fixed to the handwheel 19 in the middle, and the other drive sprocket is connected to the sprocket located below it via a rotating shaft. The handwheel 19 and the drive chain drive the sprocket inside the protective box 16 to rotate, and the sprocket inside the protective box 16 drives the chain to rotate. The chain drives the lifting platform 13 to move up and down along the vertical slide bar 12 through the connecting plate 17, thereby adjusting the height of the bottom of the sampling cylinder 15.

[0028] In one embodiment, a disc with a limiting hole is fixedly connected to one end of the top of the support platform 10, the support frame 1 is rotatably connected to the disc, and a limiting pin 11 that mates with the limiting hole is inserted into the outer side of the support frame 1.

[0029] It should be noted that in this embodiment, multiple limiting holes are equidistantly provided on the outer side of the disk. The disk is rotatably connected to the support frame 1. One end of the support frame 1 is inserted with a limiting pin 21 that cooperates with the limiting hole. This allows the limiting pin 21 to rotate around the center. When the limiting pin 21 on the outer side of the limiting pin 21 cooperates with the corresponding limiting hole, the limiting pin 21 passes through the support frame 1 and cooperates with the limiting hole, thereby achieving the included angle between the support frame 1 and the disk.

[0030] In one embodiment, one end of the movable wheel 3 is fixedly connected to a rotating tube 2, the rotating tube 2 is rotatably mounted on the outside of the support frame 1, a limiting pin 4 is inserted into the middle of the rotating tube 2, and the support frame 1 has a through hole that cooperates with the limiting pin 4.

[0031] It should be noted that in this embodiment, a cylinder that cooperates with the rotating tube 2 is welded to the middle of the support frame 1. The angle of the moving wheel 3 can be adjusted by rotating the rotating tube 2 on the outside of the cylinder. After the adjustment is completed, the limiting pin 4 is inserted through the rotating tube 2 into the through hole in the middle of the support frame 1, so as to fix the angle of the moving wheel 3, thereby facilitating the transportation of the entire equipment. When sampling, the moving wheel 3 is rotated to one side of the support frame 1 to prevent the moving wheel 3 from obstructing the rotation of the support frame 1.

[0032] In one embodiment, two brackets 8 are fixedly connected to the middle of the support frame 1. A limiting rod 9 that limits the vertical slide rod 12 is slidably connected to one side of the bracket 8. A spring that drives the limiting rod 9 to move towards the top of the vertical slide rod 12 is sleeved at the end of the limiting rod 9.

[0033] It should be noted that in this embodiment, when the vertical slide rod 12 is rotated to the end of the bracket 8 in the middle of the support frame 1, because the limiting rod 9 has a U-shaped structure, one end of the limiting rod 9 is slidably connected to the bracket 8, and a spring is installed at its end, thereby pulling the end of the limiting rod 9 toward the middle of the support frame 1. The end away from the spring limits the vertical slide rod 12 to the end of the bracket 8, preventing the support frame 1 from separating from the vertical slide rod 12.

[0034] In one embodiment, both sides of the support frame 1 are threaded with adjusting screws 6, and the ends of the adjusting screws 6 on both sides are rotatably connected to limit grooves, with the receiving box 5 placed between the two limit grooves.

[0035] It should be noted that in this embodiment, the receiving box 5 includes a box body and a top cover. The box body is fixedly connected to the support frame 1. The inside of the box body is provided with a groove for storing samples. When storing, the sample is placed inside the box body, the top cover is placed on the top of the box body, and then the fixing slot 7 is rotated. Under the action of the thread, the fixing slot 7 drives the end limiting slot to lock in the top and bottom of the receiving box 5, thereby locking the box body and the top cover.
