A soil sampler for land surveying can be designed with an automatic pusher mechanism or a built-in spring push device inside the sampler, which can easily push out the soil sample after the sampler is pulled out, making the sampling process more efficient and clean.

By setting the squeezing assembly, when the soil is taken out, the external controller is used to start the electric piston 33, the electric piston 33 drives the push plate 34 to squeeze the movable plate 35, and the movable plate 35 squeezes the spring 36, driving the connecting rod 37 to move, and the connecting rod 37 drives the squeezing plate 38 to slide in the sampling tube 39, thereby squeezing out the taken soil sample, so as to solve the problem that the soil sample of the existing soil sampler for land surveying often sticks to the inner wall of the sampling port after sampling and is difficult to take out directly. This usually requires the use of additional external tools to dig out the soil, which increases the complexity and time consumption of the sampling process.

[0023] See also Figure 1-Figure 4 In this embodiment, the outer end of the turntable 51 is rotatably connected to a swivel 52, and the interior of the swivel 52 is slidably connected to four limit rods 53 at equal intervals. The turntable 51 and the swivel 52 rotate, so that during the soil sampling process, positioning is convenient while not hindering the normal sampling of the device. The lower ends of the four limit rods 53 are connected to a bottom ring 54, and the lower end of the bottom ring 54 is connected to an anti-slip pad 55. The anti-slip pad 55 increases the friction with the ground to prevent the bottom ring 54 from sliding, thereby assisting the device in positioning. The tops of the four limit rods 53 are connected to limit blocks 56, and the lower sides of the outer ends of the four limit rods 53 are connected to the same limit blocks 56. The limit blocks 56 are used to limit the sliding distance of the limit rods 53 to prevent the limit rods 53 from sliding from the swivel 52.

[0024] See also Figure 2-Figure 4In this embodiment, the limit block 56 is movably connected to the swivel 52, and there are eight limit blocks 56. The limit rod 53 is movably connected to the swivel 52 and the bottom ring 54, thereby playing a limiting role.

Turn the handle 44, and the handle 44 rotates on the rotating rod 43, thereby driving the control disk 41 to rotate. The rotation of the control disk 41 drives the main body 1 to rotate, thereby sampling the soil.

[0025] When working, first assemble the assembly tube 2 and the threaded column 31, place the anti-slip pad 55 flush with the ground, turn the handle 44, and the handle 44 rotates on the rotating rod 43, thereby driving the control disk 41 to rotate, and the rotation of the control disk 41 drives the assembly tube 2 to rotate, and the assembly tube 2 drives the threaded column 31 and the connecting tube 32 to rotate. The counterweight block 42 increases the weight of the device, making it easier to press down, and drives the sampling tube 39 to rotate, thereby sampling the soil. When the sampling tube 39 continues to extend into the soil, the bottom ring 54 will bring The limiting rod 53 slides on the rotating ring 52, the limiting block 56 is used to limit the position of the limiting rod 53, the bottom ring 54 prevents the device from shifting during sampling and prevents the device from tilting, and the anti-slip pad 55 increases the friction with the ground. After the sampling is completed, the external controller is used to start the electric piston 33, and the electric piston 33 drives the push plate 34 to squeeze the movable plate 35. The movable plate 35 squeezes the spring 36, driving the connecting rod 37 to move, and the connecting rod 37 drives the squeezing plate 38 to slide in the sampling tube 39, thereby squeezing out the taken soil sample.

[0026] Through the above steps, by setting up an extrusion assembly, when the soil is taken out, the electric piston 33 is started by using an external controller, and the electric piston 33 drives the push plate 34 to squeeze the movable plate 35, and the movable plate 35 squeezes the spring 36, driving the connecting rod 37 to move, and the connecting rod 37 drives the extrusion plate 38 to slide in the sampling tube 39, thereby squeezing out the taken soil sample, so as to solve the problem that after sampling, the soil sample of the existing soil sampler for land surveying often sticks to the inner wall of the sampling port and is difficult to be directly taken out. This usually requires the use of additional external tools to dig out the soil, which increases the complexity and time consumption of the sampling process.
