[0025] Example

[0026] Please see Figures 1-5 This utility model provides a land resource exploration and sampling device, including an external sampling component 10 and an internal sampling component 20.

[0027] By combining the external sampling component 10 and the internal sampling component 20, the sampling device can sample soil from deeper locations, making it more versatile.

[0028] Please see Figure 1 , Figure 2 and Figure 5 The external sampling component 10 includes a main tube 110, a connecting tube 120, and a nut 130. The connecting tube 120 is detachably installed at the lower end of the main tube 110, and the nut 130 is fixedly installed at the top end of the main tube 110. The internal sampling component 20 includes a telescopic rod 210, a handle 220, and a spiral blade 230. The spiral blade 230 is fixedly installed on the outside of the lower section of the telescopic rod 210, and the upper section of the telescopic rod 210 movably passes through the top end of the main tube 110 and is screwed to the nut 130. The handle 220 is installed radially outward at the top end of the telescopic rod 210.

[0029] When sampling soil at greater depths, the connecting pipe 120 can be installed below the main pipe 110. For even deeper sampling, multiple connecting pipe sections 120 can be connected. The connecting pipe 120, main pipe 110, and spiral blade 230 are inserted into the soil to the sampling position, with the spiral blade 230 outside the connecting pipe 120. Rotating the handle 220 causes the telescopic rod 210 and spiral blade 230 to rotate. The rotating spiral blade 230 moves the soil upwards into the connecting pipe 120, collecting the sampled soil inside. This land resource exploration sampling device is more suitable for sampling soil at greater depths and has better applicability.

[0030] For specific settings, please refer to Figure 1 and Figure 4 A positioning ring 140 is fixedly sleeved on the outside of the main tube 110, and a foot pedal 150 is provided on the positioning ring 140, which is movably sleeved on the outside of the main tube 110. The foot pedal 150 includes a pedal 151 and a limiting ring 152. The limiting ring 152 is movably sleeved on the outside of the main tube 110, and the pedal 151 is fixed on the outside of the limiting ring 152.

[0031] By stepping on the pedal 151 in the foot pedal 150, it is easier to drive the sampling part of the device into the soil.

[0032] Furthermore, the foot pedal 150 also includes an anti-slip pad 153, which is fixedly mounted on the upper surface of the pedal 151. The anti-slip pad 153 is made of anti-slip rubber with good anti-slip performance, which will provide better anti-slip effect when stepping on the pedal 151.

[0033] In the specific implementation described above, please refer to Figure 2 and Figure 3 The main tube 110 has a first scale mark 112 on its exterior, and the connecting tube 120 has a second scale mark 123 on its exterior. The first scale mark 112 and the second scale mark 123 are designed to improve the accuracy of the sampling position inside the soil.

[0034] In the specific configuration, the main tube 110 has a first external thread 111 at its bottom, the connecting tube 120 has an internal thread 121 that mates with the first external thread 111 at its top, and the connecting tube 120 has a second external thread 122 at its bottom that is identical to the first external thread 111. That is, the main tube 110 and the connecting tube 120 are installed by screwing, and another connecting tube 120 can be screwed in below the connecting tube 120.

[0035] For details, please refer to Figure 5The telescopic rod 210 includes a lower rod 211, an upper rod 212, and a connecting rod 213. The connecting rod 213 is detachably connected to the upper rod 212 and the lower rod 211 via fixing bolts 214. The length of each connecting rod 213 is the same as the length of the connecting pipe 120. The number of connecting rods 213 between the upper rod 212 and the lower rod 211 increases accordingly based on the number of sections of the connecting pipe 120. The sampling internal component 20 also includes a convex cone 240, which is located at the bottom end of the lower rod 211. The convex cone 240 makes it easier for the bottom end of the device to penetrate into the soil.

[0036] The working principle of this land resource exploration sampling device is as follows: When sampling soil at greater depths, the connecting pipe 120 can be installed below the main pipe 110. For even deeper sampling, multiple connecting pipe sections 120 can be connected. The connecting pipe 120, main pipe 110, and spiral blade 230 are inserted into the soil to the sampling position, with the spiral blade 230 outside the connecting pipe 120. Rotating the handle 220 causes the telescopic rod 210 and spiral blade 230 to rotate. The rotating spiral blade 230 moves the soil upwards into the connecting pipe 120, collecting the sampled soil inside the connecting pipe 120. This land resource exploration sampling device is more suitable for sampling soil at greater depths and has better applicability.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
