The adjusting screw block 7 can drive the driven rod 9 to move during the rotation in the threaded groove 6. The inclined blocks 10 can push the pusher blocks 11 to move during the movement to achieve the effect of feeding materials.

[0022] like Figure 1 As shown, casters 22 are rotatably connected to the bottom of the base 1 near the four corners. Two connecting blocks 23 are fixedly connected to both sides of the base 1. Each of the four connecting blocks 23 has a fixing nail 24 inserted inside. The casters 22 facilitate the movement of the device, while the fixing nails 24 can fix the device and prevent it from shaking.

[0023] like Figure 3 and Figure 4As shown, a sealing groove 12 is provided at the top of the sampling rod 4 and at the edge of the sampling groove 5. The interior of the sealing groove 12 is connected to the interior of multiple sampling grooves 5. A sealing plate 13 is inserted into the interior of the sealing groove 12. By setting the sealing plate 13, the sampling groove 5 can be sealed to prevent soil from entering the sampling rod 4 during the drilling process and improve the accuracy of sampling.

[0024] like Figure 2 and Figure 4 As shown, a fixing plate 14 is fixedly connected to the top of the sampling rod 4 and at the edge of the sampling groove 5. Two fixing screw holes 15 are opened through the outer surface of the sealing plate 13. A fixing bolt 16 is threaded inside one of the fixing screw holes 15. The other end of the fixing bolt 16 is threaded to the front part of the fixing plate 14.

[0028] This utility model provides a stratified sampling device for mineral exploration, the specific working principle of which is as follows:

[0029] During exploration and sampling, staff use the casters 22 to push the device to the designated sampling location. Then, using tools, they insert the fixing nails 24 into the ground. After fixing, the lifting mechanism 2 is activated, moving the mounting plate 3 downwards. The drive motor 20 drives the sampling rod 4, fixed to the fixed gear 21, to rotate, allowing the sampling rod 4 to penetrate deeper into the strata. Once in position, the lifting mechanism 2 and drive motor 20 stop. Staff then pull the sealing plate 13 upwards and secure it with the fixing bolts 16 to open the sampling slot 5. At this point, the drive motor 20 is activated again, allowing the sampling rod to... 4 rotates, scraping surrounding materials into the sampling groove 5 during the rotation. After sampling, the staff resets and fixes the sealing plate 13, and then uses the lifting mechanism 2 to pull the sampling rod 4 away from the bottom surface. When the sample is taken out, the staff opens the sealing plate 13 and rotates it to the adjusting screw block 7. The adjusting screw block 7 pushes the driven rod 9 to move downward in the adjusting groove 8. During the movement, the inclined block 10 applies pressure to the pushing block 11. Under the action of pressure, the pushing block 11 slides outward along the sampling groove 5, pushing out the sample in the sampling groove 5 for easy collection and storage by the staff.
