[0004] In view of the above description, the applicant believes that the following problems exist:
[0005] During use, the utility model completes the sampling of rock powder by closing the fan-shaped opener. When inserted, it is in a closed state, and the sampling is carried out in the rock powder layer. After grabbing the rock powder, it is closed and taken out to complete the sampling. However, in actual use, when sampling, the rock powder of different layers are all loaded inside the cylinder and mixed together.

[0029] Furthermore, the sampling mechanism 7 includes a rotating seat 71, which is rotatably installed inside the cylinder 3, and an arc-shaped baffle 72 is fixedly installed on the bottom of the rotating seat 71. A spring 73 is fixedly installed inside the cylinder 6, and a disc 74 is fixedly installed on the end of the spring 73 away from the cylinder 6.

An anti-slip block 78 is fixedly installed on the end of the spring 77 away from the rotating shaft 76, and a plug 79 is fixedly installed inside the anti-slip block 78 to fix the position of the rotating shaft 76.
[0030] Furthermore, the plug post 79 is slidably installed inside the rotating shaft 76, and a socket is opened at the corresponding position of the cylinder 2 6 and the plug post 79, and the plug post 79 is inserted into the inside of the socket, and the anti-slip block 1 78 is slidably installed inside the rotating shaft 76, driving the plug post 79 to move.
[0031] Furthermore, the rotating shaft 76 is movably installed inside the cylinder 2 6, the disc 74 is slidably installed inside the cylinder 2 6, the positioning column 2 75 is inserted into the inside of the cylinder 1 3, the bottom of the rotating shaft 76 is inserted into the inside of the rotating seat 71, and the arc baffle 72 is movably installed inside the cylinder 1 3 to cover the storage trough 82 and preserve rock powder of different depths.
[0032] Embodiment 2:
[0033] See also Figure 5 , and combined with Example 1, it is further obtained that the installation mechanism 8 includes a sampling block 81, the sampling block 81 is arranged inside the cylinder 3, a material storage trough 82 is opened inside the sampling block 81, two springs 3 83 are fixedly installed inside the sampling block 81, and the ends of the two springs 3 83 away from the sampling block 81 are fixedly installed with anti-slip blocks 2 84, the top of the anti-slip block 2 84 is fixedly installed with a control column 85, and the side of the anti-slip block 2 84 away from the spring 3 83 is fixedly installed with an insert block 86, thereby completing the quick installation of the sampling block 81.
[0034] Furthermore, the insert block 86 is inserted into the interior of the cylinder 1 3 , and the control column 85 is movably installed inside the sampling block 81 , driving the anti-fall-off block 2 84 to move.
[0035] Furthermore, the anti-drop block 84 is slidably installed inside the sampling block 81, and the sampling block 81 is arranged between the cylinder 1 3 and the arc-shaped baffle 72, so that a new sampling block 81 can be quickly replaced and installed for the next sampling, so that the sampling work can be completed in the shortest time and is safer.
[0036] In actual operation, when this device is used, the arc-shaped baffle 72 initially blocks the material storage trough 82, the rectangular plate 1 is moved close to the sampling position, the positioning post 1 2 is inserted into the sampling layer, and the rectangular plate 1 is positioned and installed so that the cylinder 3 can only move vertically when sampling, and the rotating shaft 76 is pulled up. Since the disc 74 rotates on the outside of the rotating shaft 76, the rotating shaft 76 drives the disc 74 to rise, so that the disc 74 squeezes the spring 1 73, and the spring 1 73 is compressed. The spring 1 73 is initially in a stretched state, and the positioning post 2 75 and the four positioning post 2 75 are all retracted to the inside of the cylinder 2 6, and the cylinder 2 6 is threadedly installed in the inside of the cylinder 1 3 through the threaded barrel 5, and then the rotating shaft is released. The spring 73 rebounds and drives the disc 74 to descend, thereby driving the disc 74 and the shaft 76 to descend, and the positioning column 2 75 is inserted into the interior of the cylinder 1 3, so that the cylinder 1 3 and the cylinder 2 6 are installed. The cylinder 1 3 and the threaded cylinder 5 will not rotate when in use, so that the cylinder 1 3 and the cylinder 2 6 are installed firmly. The height of the cylinder 2 6 can be selectively installed according to the rock powder stacking height of each mining sampling site, so as to ensure that the deeper rock powder layer can be sampled. The shaft 76 descends and is inserted into the interior of the rotating seat 71, so that the rotating seat 71 and the rotating shaft 76 can rotate synchronously, pressing the cylinder 2 6 downward, so that the cylinder 1 3 is pressed downward under the action of the drill bit 4. When the required sampling position is reached, After the screwdriver is in the state of being rotated, the screwdriver 73 is turned to the left and the screwdriver 73 is turned to the right, and the screwdriver 73 is turned to the left and the screw driver 73 is turned to the right, so that the screw driver 73 can rotate freely. Multiple samplings are more efficient. Then pull up the cylinder 2 6 to drive the cylinder 1 3 to rise, take out the device and lay it flat. After the above operation opens the arc baffle 72, pinch the two control columns 85 inward to make the anti-detachment block 2 84 drive the insertion block 86 to separate from the interior of the cylinder 1 3. At this time, the spring 3 83 is compressed, and the spring 3 83 is initially in a stretched state. The sampling block 81 can be separated from the interior of the cylinder 1 3, which is convenient for quick replacement and installation of a new sampling block 81 for the next sampling, so that the sampling work can be completed in the shortest time and is safer. Subsequently, the rock powder of different depths in the multiple storage troughs 82 can be taken out. The multiple storage troughs 82 are independent of each other to avoid interference with the detection of rock powder of different depths after mixing.
