At this time, the sampling component is driven by the driving component to perform lifting and rotation movements, so that the sampling component extends from the bottom of the insert tube 18, and then the mineral soil is drilled and sampled. It is mainly driven by the second motor 15 to rotate the rotating shaft 21, so that the spiral collection leaves 22 spirally extrude and transport the soil squeezed from all sides upward, so that the soil is finally discharged from the discharge port 19 and falls into the sample tube 20 for collection. Through the above structure, the mineral soil at the specified depth position can be directly collected without drilling holes from top to bottom to transport soil samples, thereby effectively improving the accuracy of sampling and detection of mineral soil.

[0021] A driving assembly is arranged on the top of the sampling assembly, and the driving assembly is used to drive the sampling assembly to perform lifting and rotating motion. The driving assembly includes a second motor 15, and the second motor 15 is installed on the top of the rotating shaft 21. A movable plate 12 is arranged in the middle of the bottom end of the second motor 15, and the movable plate 12 is movably installed in the middle of the inner side of the main body 10. Connecting blocks 13 are arranged in the middle of both ends of the movable plate 12, and the connecting blocks 13 extend out of the main body 10. Hydraulic rods 14 are arranged in the middle of both ends of the main body 10, and the output ends of the hydraulic rods 14 are fixedly connected to the connecting blocks 13.

When the movable plate 12 descends, the rotating shaft 21 is pressed down, so that the rotating shaft 21 drives the drill bit 23 to extend out of the insert tube 18 to drill holes and sample the soil. When the movable plate 12 rises, the sampling component is retracted into the insert tube 18 for hidden storage, thereby avoiding the sampling component from being exposed to the outside world for a long time and causing damage.

A hydraulic cylinder 5 is arranged on the top of the lifting frame 3. The hydraulic cylinder 5 is fixedly installed in the middle of the upper end of the support beam 2. The hydraulic cylinder 5 can drive the lifting frame 3 to perform lifting and sliding movements.

[0024] Among them, the first motor 9 drives the transmission gear 8 to rotate, so that the outer ring gear 7 drives the rotating body 6 to rotate in the middle of the inner side of the lifting frame 3, thereby driving the main body 10 and the insert cylinder 18 to rotate, and then cooperate with the hydraulic cylinder 5 to push down, so that the insert cylinder 18 can easily drill the ground.

[0025] In some examples, limit guide columns 4 are provided on both sides of the upper end of the lifting frame 3. The limit guide columns 4 are respectively located on both sides of the hydraulic cylinder 5 and are movably connected to the support beam 2. The limit guide columns 4 play a limiting role, thereby improving the stability of the lifting frame 3 during lifting and sliding.

[0026] In some examples, a fixing assembly is provided at the bottom of the support frame 1, and the fixing assembly includes multiple groups of fixing blocks 24.

The support plate 26 plays a role of limiting, further improving the stability of the insert tube 18 when it is lifted and lowered.

[0029] In some examples, the top of the drill bit 23 is configured as a conical structure to facilitate reinserting the drill bit 23 into the bottom position of the insert 18 to form a sealing structure.

[0030] Example 2: Reference Figure 1 - Figure 5 As shown, based on Example 1, a sampling method for mineral geological exploration comprises the following steps: S1. Carry the sampling device to the designated sampling location, place it firmly, and reinforce and install it with fixing components; S2, the main body 10 drives the insert 18 to press down and penetrate into the mineral ground by pushing through the hydraulic cylinder 5, and at the same time, the first motor 9 is started to drive the rotating body 6 to rotate, so that the main body 10 drives the insert 18 to rotate and drill until the insert 18 reaches the specified depth; S3. The sampling assembly is driven by the driving assembly to descend and rotate, so that the drill bit 23 extends from the bottom of the insert tube 18 and descends into the soil. The spiral collection blade 22 is driven by the rotating shaft 21 to rotate, so that the soil can be collected and transported to the insert tube 18 until it is discharged from the discharge port 19 and falls into the sample tube 20, thereby completing the sampling work.

[0031] The working principle of the present invention is: During use, the staff first moves the sampling device to the location to be sampled and places it firmly, and reinforces and fixes the support frame 1 through multiple sets of fixing nails 25 of the fixing assembly to further improve the stability of the sampling device during operation; Then, the hydraulic cylinder 5 on the top of the support beam 2 is started, and the hydraulic cylinder 5 is used to push the lifting frame 3 to perform lifting and lowering movements, and the two sets of limit guide pillars 4 are used to perform limit guiding, so that the lifting frame 3 can perform stable lifting and lowering movements. When the hydraulic cylinder 5 pushes the lifting frame 3 to descend, a compressive force is formed, so that the main body 10 pushes the insert tube 18 to penetrate the ground to drill a hole. At the same time, during the drilling process of the insert tube 18, the first motor 9 is started to drive the transmission gear 8 to rotate, thereby driving the outer gear ring 7 to rotate. The rotation of the outer gear ring 7 can drive the rotating body 6 to rotate in the lifting frame 3, thereby driving the main body 10 and the insert tube 18 to perform rotational movement, thereby realizing rotary drilling of the mineral ground, making it easier for the insert tube 18 to drill into the soil, and stopping when the insert tube 18 drills to a specified depth position; At this time, multiple groups of hydraulic rods 14 are used to push the movable plate 12 to descend in the main body 10, so that the drill bit 23 extends from the bottom of the insert tube 18, and the drill bit 23 drives the rotating shaft 21 to continue drilling downward; at the same time, the second motor 15 is started, and the rotating shaft 21 is driven to rotate by the second motor 15, thereby driving the spiral collection leaf 22 to rotate, so that the surrounding soil is rotated and transported, and the spiral collection leaf 22 is rotated to rotate the soil into the inner cavity of the insert tube 18, and finally discharged from the discharge port 19 and falls into the sample tube 20, thereby completing the sampling work.

[0032] After the sampling work is completed, the movable plate 12 is driven to rise again by the hydraulic rod 14, so that the drill bit 23 can be reinserted into the bottom of the insert 18 to form a sealing structure. At this time, the soil inside the insert 18 can be used as a backup.

[0033] Through the above structure, at the beginning of sampling, the sampling device is hidden and stored in the insert tube 18. At this time, the drill bit 23 can cover and seal the opening at the bottom of the insert tube 18, so as to keep the inner cavity of the insert tube 18 clean and prevent the surface soil from mixing into the insert tube 18 to affect the sampling accuracy. When the insert tube 18 reaches the specified position, the sampling assembly is started again to directly collect the soil at the specified depth position; after the sampling work is completed, the hydraulic rod 14 drives the movable plate 12 to rise, so that the drill bit 23 is reinserted into the bottom of the insert tube 18, and the bottom of the insert tube 18 is sealed again to prevent the spare soil in the inner cavity of the insert tube 18 from falling during the extraction process, and at the same time, it also effectively prevents the surface soil from entering the inner cavity; The present invention can directly collect soil at a designated location through the above structure, thereby effectively improving the accuracy of sampling and testing of mineral soil. In addition, the sampling component is rotated in the insert 18, so that even if muddy soil is encountered, the muddy soil can be easily collected.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
