A feed port 22 and a baffle 24 are provided on the side of the barrel 2, and the baffle 24 is moved along the side of the barrel 2 to open and close the feed port 22. When taking powder, the baffle 24 is moved to open the feed port 22, and the handle 1 is turned, and the conical head 4 drives the barrel 2 to drill into the powder to achieve powder sampling in the vertical direction. When the sampling is completed, the handle 1 is pulled to drive the barrel 2 to be pulled out of the powder, and the baffle 24 is moved to close the feed port 22.

[0032] In this embodiment, multiple barrels 2 are connected in series in a detachable manner, so as to reasonably adjust the total length of the barrels 2. The barrel 2 at the top is detachably connected to the handle 1, and the conical head 4 is connected to the bottom of the last barrel to assist the barrel 2 in inserting into the powder, so as to achieve smooth insertion of the barrel 2 into the powder. The top and bottom of the barrel 2 are sealed, and since the barrels 2 are completely isolated from each other, it is ensured that the powder samples taken will not be mixed; at the same time, the side of the barrel 2 is provided with a feed port 22 and a baffle 24. By turning the baffle 24, the feed port 22 can be opened and closed as needed to meet the material taking needs and avoid the powder in the barrel 2 from spilling.

[0033] In this embodiment, the width of the baffle 24 is slightly larger than the width of the feed opening 22 so as to completely cover the feed opening 22, thereby preventing the powder in the barrel 2 from spilling and improving the reliability of sampling.

[0034] like Figure 2 As shown, in this embodiment, the first plug hole 23 and the third plug hole 26 are symmetrically welded on the left and right sides of the feed port 22, and the second plug hole 25 is welded on the side of the baffle 24. Figure 2 As shown, before sampling, the pin 3 is inserted into the first insertion hole 23 on the left side of the feed port 22 and the second insertion hole 25 on the side of the baffle 24 to achieve full opening of the feed port 22; Figure 3 As shown, after sampling, the pin 3 is inserted into the third insertion hole 26 on the right side of the feed port 22 and the second insertion hole 25 on the side of the baffle 24 to achieve complete closure of the feed port 22.

When the feed port 22 is fully opened, the second plug hole 25 is located between the two first plug holes 23, and the pin 3 is inserted into the second plug hole 25 and the two first plug holes 23 to fix the baffle 24. When the feed port 22 is fully closed, the second plug hole 25 is located between the two third plug holes 26, and the pin 3 is inserted into the second plug hole 25 and the two third plug holes 26 to fix the baffle 24.

[0036] like Figure 4 As shown, in this embodiment, the barrel 2 adopts a double-layer hollow structure, and a baffle 24 is provided in the barrel wall interlayer near the feed port 22. The baffle 24 can slide left and right in the barrel wall interlayer near the feed port 22 to open or close the feed port.

[0037] like Figure 1 As shown, in this embodiment, the handle 1 is about 15 to 20 cm long and about 2 cm in diameter. It is located at the top of the sampler as a force point for extracting or rotating the sampler. A connecting rod 11 is welded in the middle of the handle 1. The bottom of the connecting rod 11 is provided with an internal thread. The connector 21 at the top of the barrel 2 is provided with an external thread. The bottom of the barrel 2 is provided with an internal thread. The top of the conical head 4 is provided with an external thread. The barrel 2 and the connecting rod 11, the adjacent barrels 2, and the barrel 2 and the conical head 4 are all connected by threads, which has the characteristics of simple structure, reliable connection and convenient use.

[0038] Furthermore, the diameter of the barrel 2 is 10 cm, the height is 20 cm, and the amount of powder contained in a single barrel 2 is greater than 500 g. Four barrels 2 are connected in series between the handle 1 and the conical head 4, which are used to extract powder at depths of 0.8 m, 0.6 m, 0.4 m and 0.2 m, respectively, meeting the needs of powder sampling.

[0039] When the powder transport vehicle arrives for sampling, the sampler can be assembled according to the observed powder depth, and the conical head 4 can be connected in series after connecting multiple barrels 2 to the required length. The baffle 24 of each barrel 2 is moved to the leftmost side of the feed port 22, and the pin 3 is inserted in series into the first jack 23 and the second jack 25 to ensure that the feed port 22 is fully open. Hold the handle 1 and insert it into the powder and rotate it several times before pulling it out. The powder enters the barrel 2 through the feed port 22, pull out the pin 3, and move the baffle 24 to the rightmost side of the feed port 22. The pin 3 is inserted in series into the third jack 26 and the second jack 25 again to ensure the closure of the feed port 22, and the sampler is taken back to the laboratory. The powder in the barrel 2 at different positions is selected for testing as needed. The sampler of this embodiment is simple and convenient to use and operate, and the length can be adjusted according to actual needs. At the same time, each layer is completely closed and isolated to ensure that the powder samples taken will not be mixed.
