The device also comprises a first lug 3, a second lug 4, a scraping plate 5 and a connecting plate 6; each inner material port 2001 on the inner barrel 2 is connected with a first convex block 3 which is symmetrical in center; two second convex blocks 4 which are symmetrical in center are connected to each inner material opening 2001 on the inner cylinder 2; each of the first bump 3 and the second bump 4 is located in an adjacent sliding groove 1002; two bilaterally symmetrical scraping plates 5 are connected to each outer material opening 1001 on the outer cylinder 1, and the scraping plates 5 are deformable plates; each two adjacent scraping plates 5 are fixedly connected with a connecting plate 6 on opposite sides; each two adjacent connecting plates 6 are provided with a bevel 6001 on opposite sides.
Also included are a first handle 101 and a second handle 102; the upper side of the outer cylinder 1 is fixedly connected with a first handle 101; a second handle 102 is fixedly connected to the upper side of the inner cylinder 2.
Firstly, a worker holds the outer cylinder 1 with one hand and holds the first handle 101 with the other hand, then forcefully obliquely inserts the outer cylinder 1 into the coal pile in an upward mode of the outer material port 1001, gradually pushes the outer cylinder 1 into the deep of the coal pile, and enables the inner cylinder 2 to enter the deep of the coal pile along with the outer cylinder 1, so that the preparation work of coal sampling is completed.
Subsequently, the worker holds the second handle 102, based on the above, and rotates the second handle 102 counterclockwise by one hundred eighty degrees, thereby driving the inner cylinder 2 and the inner port 2001 to rotate counterclockwise by one hundred eighty degrees, and further driving the first bump 3 and the second bump 4 to rotate in the same manner along the sliding groove 1002, so that the inner port 2001 gradually coincides with the position of the outer port 1001 (the inner port 2001 does not coincide with the initial state of the outer port 1001, and the initial position of the inner port 2001 is opposite to the outer port 1001), thereby allowing coal to enter the storage cavity in the inner cylinder 2 along the outer port 1001 and the inner port 2001 under the action of gravity, but since the coal contacting the cylinder wall of the outer cylinder 1 is pressed under the extrusion of the outer cylinder 1 during the insertion of the outer cylinder 1 into the coal pile, the coal is difficult to fall into the storage cavity in the inner cylinder 2 under the action of gravity, and therefore, the amount of coal falling into the storage cavity is small, and the amount of coal required by coal sampling is difficult to meet, so that in the process of rotating the first lug 3 and the second lug 4, the first lug 3 extrudes the scraper 5, so that the scraper 5 deforms, the scraper 5 is tilted, the connecting plate 6 is driven to tilt together, the outer side of the scraper 5 protrudes out of the wall of the outer cylinder 1, the tilted part of the scraper 5 is inserted into a coal pile, then a worker holds the first handle 101 by both hands, the first handle 101 performs alternating rotation (the movement form of periodically changing the rotation direction of an object) so as to drive the outer cylinder 1 and the inner cylinder 2 to perform alternating rotation, further drive the first lug 3, the second lug 4 and the scraper 5 to perform alternating rotation, the tilted part of the scraper 5 scrapes the coal pile, the scraped coal becomes soft, and then the coal enters the storage cavity in the inner cylinder 2 along the outer material port 1001 and the inner material port 2001 under the action of gravity, so that the storage cavity is gradually filled with coal, the coal is sampled, the coal is prevented from being too compact after being extruded by the outer cylinder 1, the coal is difficult to fall into the storage cavity, and the device is influenced to sample the coal.
Subsequently, after the completion of the coal sampling, in order to avoid that the outer port 1001 and the inner port 2001 positioned at the deepest part of the coal pile enter the storage cavities corresponding to the outer port 1001 and the inner port 2001 along the outer port 1001 and the inner port 2001 when the outer port 1 is moved out of the coal pile in the process of extracting the coal pile, the coal sample in the storage cavities is polluted to influence the subsequent detection of the coal sample, therefore, before the outer port 1 is extracted from the coal pile, the storage cavities need to be sealed, so that after the completion of the coal sampling, a worker holds the second handle 102 and rotates the second handle 102 counterclockwise by one hundred eighty degrees based on the view from the top, thereby driving the inner cylinder 2 and the inner material port 2001 to rotate anticlockwise by one hundred eighty degrees, so that the inner material port 2001 rotates to an initial position, so that the outer material port 1001 and the inner material port 2001 are dislocated, and the storage cavity is closed, but in the process, if coal blocks exist on the outer material port 1001 and the inner material port 2001, the outer material port 1001 and the inner material port 2001 are extremely easy to be blocked by the coal blocks, so that the inner cylinder 2 cannot rotate, so that the outer material port 1001 and the inner material port 2001 cannot be dislocated, and the storage cavity cannot be closed, therefore, before the inner cylinder 2 rotates anticlockwise by one hundred eighty degrees, a worker holds the second handle 102, The second handle 102 is rotated clockwise based on the top-down view, thereby driving the first bump 3 and the second bump 4 to rotate clockwise, as shown in fig. 7, when the second bump 4 is rotated to the pressing portion 1003, the second bump 4 is pressed by the pressing portion 1003, so that the second bump 4 presses the edge portion 2002 of the inner cylinder 2, thereby deforming the edge portion 2002 after being pressed, and recessing inwards, and simultaneously, the first bump 3 gradually enters the sliding groove 1002 after being rotated, so that the squeegee 5 is disengaged from the pressing of the first bump 3, thereby gradually restoring the shape, thereby driving the connection plate 6 to gradually restore the shape, and then, based on the top-down view, The staff rotates the second handle 102 anticlockwise, so as to drive the inner cylinder 2 anticlockwise, and then drive the first lug 3 and the second lug 4 to rotate in the same way, so that the second lug 4 is far away from the extrusion part 1003, and the second lug 4 is separated from the extrusion of the extrusion part 1003, so that the second lug 4 is quickly restored to the original state, and the edge part 2002 is quickly restored, so that the edge part 2002 pushes the coal blocks clamped on the outer material port 1001 and the inner material port 2001 in the restoration process, simultaneously, the first lug 3 also quickly extrudes the scraping plate 5 again, so that the scraping plate 5 and the connecting plate 6 quickly become a tilted state, therefore, the inclined plane 6001 on the connecting plate 6 capable of tilting rapidly pries the coal blocks clamped on the outer material port 1001 and the inner material port 2001, so that the coal blocks move to the outer side of the outer material port 1001, the operation is repeated for a plurality of times until the coal blocks are not clamped on the outer material port 1001 and the inner material port 2001 any more, the coal block clamping treatment on the outer material port 1001 and the inner material port 2001 is realized, the phenomenon that the coal blocks clamped on the outer material port 1001 and the inner material port 2001 block the rotation of the inner barrel 2 is avoided, the storage cavity cannot be closed, and the subsequent detection result of coal is affected.
Then, after the storage cavity is closed, the worker holds the first handle 101 by hand and pulls out the outer cylinder 1 out of the coal pile by force, so that the inner cylinder 2 is driven to move out of the coal pile, then, based on the condition that the worker looks down from top, the worker rotates the inner cylinder 2 for one hundred eighty degrees again, the positions of the outer material port 1001 and the inner material port 2001 are overlapped, and then, the coal in the storage cavity is poured out along the outer material port 1001 and the inner material port 2001, so that layered sampling of the coal is realized.
As shown in fig. 6, each first bump 3 protrudes from an adjacent inner port 2001; each second bump 4 protrudes from the adjacent inner port 2001; in the process of sealing the storage cavity, if the coal blocks on the outer material port 1001 and the inner material port 2001 do not clamp the outer material port 1001 and the inner material port 2001, only the coal blocks exist between the outer material port 1001 and the inner material port 2001, at this time, when the inner cylinder 2 rotates, after the edge portion 2002 contacts with the coal blocks, the edge portion 2002 drives the coal blocks to rotate together, then when the coal blocks move to contact with the scraping plate 5 on the other side, the coal blocks can clamp between the scraping plate 5 and the edge portion 2002, so that the inner cylinder 2 is clamped by the coal blocks, before the edge portion 2002 contacts with the coal blocks, the coal blocks are firstly contacted with the coal blocks through the first protruding block 3 and the second protruding block 4, so that the coal blocks are clamped between the scraping plate 5 and the edge portion 2002, and become clamped between the first protruding block 3 and the second protruding block 4 and the scraping plate 5, at this time, the working personnel continue to rotate the inner cylinder 2, the first protruding block 3 and the second protruding block 4 continue to rotate, so that the coal blocks are clamped between the first protruding block 3 and the second protruding block 4 and the coal blocks along the first protruding block 3 and the second protruding block 4, the position of the coal blocks is not clamped between the outer cylinder 1 and the outer cylinder 1, and the coal blocks are prevented from being clamped, and the coal blocks cannot be clamped between the outer cylinder 1 and the outer cylinder 1, and the coal blocks are prevented from being clamped, and the coal blocks from being clamped between the positions, and the coal blocks are prevented from being continuously moving outside the coal blocks, and the coal blocks.

In the process of pulling the outer cylinder 1 out of the coal pile by a worker, the outer cylinder 1 is pressed by coal by the coal pile to ensure that the outer cylinder 1 is extremely laborious to pull out, so before the outer cylinder 1 is pulled out, when the storage cavity is closed, the second handle 102 is rotated anticlockwise by ninety degrees based on the top-down view by the worker, the first lug 3, the second lug 4 and the third lug 201 are driven to rotate anticlockwise by ninety degrees, the storage cavity is closed, the corresponding scraping plates 5 are respectively pressed by the third lug 201 of each column in the process of rotating the third lug 201, the scraping plates 5 are lifted upwards under the pressing of the third lug 201 and kept in the state, then the worker holds the first handle 101 to ensure that the first handle 101 synchronously rotates alternately, and the outer cylinder 1, the inner cylinder 2, the third lug 201 and the scraping plates 5 are gradually pulled out of the coal pile in the process, so that the part of the scraping plates 5, which is tilted, is rubbed along the coal pile pulling path, the coal pile pulling path is reduced, and the coal pile pulling efficiency of the outer cylinder 1 is reduced.
