Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 5 This utility model provides a technical solution: a coal sample sampling device, including a first sampling box 1, a base cone 7, and a second sampling box 8. An installation box 3 is fixedly installed on the top of the first sampling box 1. A worm gear 4 is rotatably connected inside the installation box 3 via a bearing. A second rotating shaft 20 is rotatably connected inside the first sampling box 1 via a bearing. One end of the second rotating shaft 20 extends into the installation box 3 and is fixedly installed with a worm wheel 19. The second rotating shaft 20 and the installation box 3 are rotatably connected via a bearing. The worm wheel 19 cooperates with the worm gear 4. A first rotating shaft 14 is rotatably connected inside the second sampling box 8. Connecting blocks 13 are fixedly installed on the outer sides of both the first rotating shaft 14 and the second rotating shaft 20. An arc-shaped baffle 9 is fixedly installed on one side of the connecting block 13. The arc-shaped baffle 9 is located inside the first sampling box 1 and the second sampling box 8 and cooperates with their inner surfaces. A sampling port 6 is opened on one side of both the first sampling box 1 and the second sampling box 8, and the sampling port 6 cooperates with the arc-shaped baffle 9.

[0021] Both the bottom of the second rotating shaft 20 and the bottom of the first rotating shaft 14 are fixedly installed with mating blocks 15. The bottom of the mating block 15 is provided with a rectangular groove 16. The top of the first rotating shaft 14 is fixedly installed with a rectangular block 17. The rectangular block 17 is inserted into the rectangular groove 16. The insertion of the rectangular block 17 into the rectangular groove 16 facilitates the installation and disassembly of the first sampling box 1 and the second sampling box 8.

[0022] Two slots 18 are provided on both sides of the bottom of the first sampling box 1 and the bottom of the second sampling box 8. Two plugs 12 are fixedly installed on the corresponding sides of the top of the second sampling box 8 and the corresponding sides of the top of the base cone 7. The two plugs 12 are inserted into the two slots 18. Bolts 10 are threadedly connected to the inside of the two plugs 12 and the two slots 18. The threads of the two plugs 12, the two slots 18 and the two bolts 10 are used to fix the first sampling box 1 and the second sampling box 8 after installation.

[0023] The first sampling box 1 has handles 2 fixed on both sides, and protective covers 11 are fitted on the outside of the two handles 2. The two handles 2 make it convenient for workers to control and carry the device.

[0024] One end of the worm gear 4 extends to the outside of the mounting box 3 and is fixedly mounted with a knob 5, which allows the worker to easily rotate the worm gear 4.

[0025] The top of the base cone 7 is provided with a placement groove 21, which is slidably connected to the mating block 15. By sliding the placement groove 21 and the mating block 15, the base cone 7 can be installed with the second sampling box 8.

[0026] Example 2: Based on Example 1, one end of the worm 4 extends to the outside of the mounting box 3 and is connected to the output shaft of the drive motor. The drive motor is connected to the mounting box 3, and the worm 4 can be rotated conveniently through the drive motor.

[0027] In summary, in this coal sample sampling device, the worm gear 4 rotates via bearings. When the sampling personnel move the device to a suitable position, during installation, they hold the second sampling box 8 by hand, aligning the two inserts 12 on top of the second sampling box 8 with the two slots 18 on the bottom of the first sampling box 1. Then, they insert the two inserts 12 into the two slots 18. Simultaneously, the rectangular block 17 is inserted into the rectangular groove 16. After insertion, another sampling personnel uses a tool to screw two bolts 10 into the two inserts 12 and the two slots 18. When installing the base cone 7, the placement groove 21 is aligned with the mating block 15, and the mating block 15 is inserted into the placement groove 21. Then, two bolts 10 are inserted into the threaded holes and the inserts 12 and fixed, achieving the purpose of post-installation fixation. When sampling coal, the sampling personnel hold the two handles 2 and use the base cone 7 to insert the device into the coal pile. The knob 5 can be rotated, causing the worm 4 to rotate. The meshing of the worm wheel 19 with the worm 4 causes the worm wheel 19 to rotate, which in turn causes the first shaft 14 and the second shaft 20 to rotate simultaneously. This rotation of the first shaft 14 and the second shaft 20 causes the arc-shaped baffle 9 to rotate, opening multiple sampling ports 6. At this time, coal will flow into the first sampling box 1 and the second sampling box 8. If necessary, the sampler can be shaken, and then the sampling personnel can do the opposite. Rotating knob 5 reverses the worm gear 4, causing the arc-shaped baffle 9 to return to its initial position and close the sampling port 6. Some of the coal remaining in the sampling port 6 will be crushed by the arc-shaped baffle 9. Then, the sampling personnel can pull out the device using the two handles 2, and then use tools to unscrew the bolts 10 to disassemble the device. Then, rotating the first shaft 14 and the second shaft 20 opens the sampling port 6, allowing the coal inside the first sampling box 1 and the second sampling box 8 to be poured out, thus achieving the purpose of coal sampling.
