[0047] The working principle and use process of the utility model are as follows: the device is placed on the top of the coal, the handle 9 is held, and force is applied to the handle 9 to make the sampling tube 1 drill into the coal, and the resistance of the device entering the coal is reduced by the soil-breaking cone 10. When the sampling tube 1 is immersed in the coal, the handle 4 is moved upward, thereby driving the fixed seat 3 and the two baffles 2 to move upward at the same time. When the sampling slot is connected to the feeding slot, the coal enters the interior of the collecting slot through the sampling slot and the feeding slot. The coal of different depths is sampled at the same time through a plurality of collecting slots, so that the detection result is more accurate. When the coal sample is collected, the fixed seat 3 and the baffle 2 are moved downward by the handle 4, so that the sampling slot is blocked by the baffle 2, and the feeding slot is blocked by the sampling tube 1, so that the collecting slot is sealed to prevent the coal sample in the collecting slot from leaking.

When the baffle plate 2 is needed to be moved upward, the two movable plates 16 are pinched so that the two movable plates 16 are close to each other, so that the limiting shaft 12 leaves the first limiting hole 14 and returns to the fixed box 11. The fixed plate and the baffle plate 2 are moved upward by the handle 4. When the limiting shaft 12 and the second limiting hole 15 are located on the same axis, the movable plate 16 is released. The limiting shaft 12 leaves the fixed box 11 under the pressure of the reset spring 13 and enters the interior of the second limiting hole 15, so that the fixing seat 3 and the baffle plate 2 are limited and cannot move. At this time, the sampling slot and the feed slot are just connected, so that the collecting slot is unobstructed, so that the device is convenient for stably limiting the baffle plate 2 and for moving the baffle plate 2, thereby improving the stability of the sampling tube 1 when sampling or storing samples.
