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 coal sampling is completed, in order to avoid that the outer bin 1001 and the inner bin 2001 positioned at the deepest part of the coal pile enter the storage cavities corresponding to the outer bin 1001 and the inner bin 2001 along the outer bin 1001 and the inner bin 2001 when the outer bin 1 is moved out of the coal pile in the process of extracting the coal pile, the coal samples in the storage cavities are polluted to influence the detection of the coal samples, therefore, before the outer bin 1 is extracted from the coal pile, the storage cavities need to be sealed, after the coal sampling is completed, a worker holds the second handle 102, and rotates the second handle 102 anticlockwise by one hundred eighty degrees based on the basis from top to bottom, so as to drive the inner bin 2 and the inner bin 2001 to anticlockwise rotate by one hundred eighty degrees, so that the inner bin 2001 rotates to the initial position, the outer bin 1001 and the inner bin 2001 are misplaced, thus realizing the sealing of the storage cavity, but in the process, if the 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, and the outer material port 1001 and the inner material port 2001 cannot be misplaced, and the storage cavity cannot be sealed, therefore, before the inner cylinder 2 rotates anticlockwise by one hundred eighty degrees, a worker holds the second handle 102, and rotates the second handle 102 clockwise based on the top, so as to drive the first lug 3 and the second lug 4 to rotate clockwise, as shown in fig. 7, when the second lug 4 rotates to the pressing part 1003, the second lug 4 is pressed by the pressing part 1003, so that the second lug 4 presses the edge part 2002 of the inner cylinder 2, the edge part 2002 deforms after being pressed and is concave inwards, simultaneously, the first lug 3 gradually enters the sliding groove 1002 after rotating, the scraper 5 is separated from the extrusion of the first lug 3 so as to gradually restore the shape, thereby driving the connecting plate 6 to gradually restore the shape, then, taking the view from top to bottom as a benchmark, the staff rotates the second handle 102 anticlockwise, thereby driving the inner cylinder 2 to anticlockwise rotate, and further driving the first lug 3 and the second lug 4 to rotate in the same mode, so that the second lug 4 is far away from the extrusion part 1003, thereby enabling the second lug 4 to be separated from the extrusion part 1003, enabling the second lug 4 to quickly restore the shape, enabling the edge part 2002 to push the coal blocks clamped on the outer material port 1001 and the inner material port 2001 in the process of restoring the shape, simultaneously, enabling the first lug 3 to quickly extrude the scraper 5 again, enabling the inclined plane 6001 on the connecting plate 6 which is quickly tilted to drive the coal blocks clamped on the outer material port 1001 and the inner material port 2001, enabling the coal blocks to move outwards to the coal blocks, repeating the operation of the inner cylinder blocks until the operation of the inner cylinder 1001 is repeated, and the coal blocks are not blocked on the inner material port 1001 and the inner material port 2001, and the coal blocks are prevented from being blocked on the inner material port 1001, and the inner material port 2001 can not be affected by the continuous rotation of the inner material port 2, and the result of the coal blocks can not be stored in the process of the closed.
