The bottom of first sampling cylinder 11 is flush with the bottom of second sampling cylinder 12, a plurality of first sampling ports 13 are arranged on the sidewall of first sampling cylinder 11 near the bottom at equal intervals, a plurality of second sampling ports 14 are arranged on the sidewall of second sampling cylinder 12 near the bottom at equal intervals, the rotation of second sampling cylinder 12 can drive second sampling port 14 to rotate, when the rotation of second sampling cylinder 12 makes first sampling port 13 and second sampling port 14 coincide, the coal sample from the outside can enter into second sampling cylinder 12 through first sampling port 13 and second sampling port 14, so that the sampling of coal is completed. When the rotation of second sampling cylinder 12 makes first sampling port 13 and second sampling port 14 staggered, the sidewall of second sampling cylinder 12 can block first sampling port 13, so that the coal from the outside will not enter through first sampling port 13, thereby avoiding the coal entering into second sampling cylinder 12.
[0032] Preferably, when sampling coal, when the rotation of second sampling cylinder 12 makes first sampling port 13 and second sampling port 14 staggered, so as to block first sampling port 13 through the sidewall of second sampling cylinder 12, first sampling cylinder 11 can be inserted into the coal, before first sampling cylinder 11 drives second sampling cylinder 12 to extend into the specified position of sampling, the coal from the outside will not enter into second sampling cylinder 12, when first sampling cylinder 11 extends into the position to be sampled, by rotating second sampling cylinder 12, the position of first sampling port 13 and second sampling port 14 coincides, the coal from the outside can enter into second sampling cylinder 12 through first sampling port 13 and second sampling port 14, so that the sampling of coal at a specified depth is realized, thereby making the detection of coal accurate.
[0033] As Figure 4 As shown, when second sampling cylinder 12 is sleeved in first sampling cylinder 11, a plurality of first sampling ports 13 and a plurality of second sampling ports 14 are flush, and a plurality of first sampling ports 13 and a plurality of second sampling ports 14 are arranged to be the same size, so that first sampling port 13 and second sampling port 14 can coincide together or be staggered when second sampling cylinder 12 rotates in first sampling cylinder 11, realizing the switching between first sampling port 13 and second sampling port 14.
[0034] AsFigure 4 and Figure 5 As shown in the drawings, the outer side wall of the first sampling cylinder 11 is fixedly connected with a first scraping plate 15 and a second scraping plate 16 on both sides of the plurality of first sampling ports 13, and the first scraping plate 15 and the second scraping plate 16 are arranged in opposite ways. When the first sampling cylinder 11 rotates, the first scraping plate 15 and the second scraping plate 16 can be driven to rotate, so that the coal at the position is scraped off by the first scraping plate 15 and the second scraping plate 16, and the coal enters the second sampling cylinder 12 through the first sampling port 13 and the second sampling port 14. The opposite arrangement of the first scraping plate 15 and the second scraping plate 16 enables the first sampling cylinder 11 to scrape off the coal for sampling regardless of the direction of rotation.

The limiting rod 21 is sleeved on the first sampling cylinder 11 and the second sampling cylinder 12 through the movable grooves 22 and the sleeve holes 23. When the second sampling cylinder 12 rotates in the first sampling cylinder 11, the limiting rod 21 can be driven to rotate. In order to facilitate the switching between the overlapping and staggered states of the first sampling port 13 and the second sampling port 14 by rotation, that is, the switching between the on and off states, the radius of the movable groove 22 matches the radius of the on-off state switching between the first sampling port 13 and the second sampling port 14, so that the rotatable radius of the limiting rod 21 in the movable groove 22 can realize the switching between the on and off states of the first sampling port 13 and the second sampling port 14.

[0040] As shown in Figure 6 , a first threaded hole 24 is arranged on the side wall of the second sampling cylinder 12 close to the upper end, and a pair of second threaded holes 25 are arranged on the side wall of the second sampling cylinder 12 and matched with the first threaded hole 24.
[0041] As shown in Figure 3 and Figure 6 , a limiting screw rod 26 is threadedly connected in the first threaded hole 24 and the second threaded hole 25, and the arc between the pair of second threaded holes 25 is the same as the arc of the limiting rod 21 rotating in the movable groove 22. When the limiting screw rod 26 is threadedly connected in the first threaded hole 24 and the second threaded hole 25, the position of the second sampling cylinder 12 can be fixed, and the rotation of the limiting rod 21 in the movable groove 22 is limited. The pair of second threaded holes 25 can be fixed when the first sampling port 13 and the second sampling port 14 are in the coinciding state and the staggered state.
[0042] As shown in Figures 1-3 , Figure 6 , a pair of handles 27 are fixedly connected on the side wall of the second sampling cylinder 12 close to the upper end, and the first sampling cylinder 11 and the second sampling cylinder 12 can be rotated by the pair of handles 27, so that the coal can be sampled by the rotation of the first sampling cylinder 11. One end of the limiting rod 21 is fixedly connected with a limiting block 28, and the limiting block 28 limits the position of the limiting rod 21 inserted into the first sampling cylinder 11 and the second sampling cylinder 12.
[0043] In use, the hand-held handle 27 extends the sampling device, i.e. the first sampling cylinder 11 and the second sampling cylinder 12, into the coal, and the first sampling port 13 and the second sampling port 14 are in the staggered state, when the first sampling cylinder 11 and the second sampling cylinder 12 are extended to the designated sampling position, the limiting screw 26 is detached from the first threaded hole 24 and the second threaded hole 25, the second sampling cylinder 12 is rotated through the handle 27, so that the second sampling cylinder 12 drives the limiting rod 21 to rotate, when the limiting rod 21 rotates in the movable groove 22 to contact the other side wall, the second sampling cylinder 12 cannot rotate, so that the first sampling port 13 and the second sampling port 14 are in the coincident state, the limiting screw 26 is screwed into the first threaded hole 24 and the corresponding second threaded hole 25, so as to limit the rotation of the second sampling cylinder 12 in the first sampling cylinder 11, the sampling device can be rotated through the handle 27, when rotating, the first scraping plate 15 and the second scraping plate 16 scrape the coal and then enter the second sampling cylinder 12 through the first sampling port 13 and the second sampling port 14, so as to realize sampling at the designated position, when the sampling is completed, the limiting screw 26 is detached, then the second sampling cylinder 12 is rotated, so that the first sampling port 13 and the second sampling port 14 are in the staggered state, and the sampling device can be extracted from the coal layer.
