[0002] Upgraded coal refers to solid coal products formed by low-rank coals such as lignite, peat, or high-volatile bituminous coal through low-temperature dehydration or pyrolysis. It can be used as a gasification feedstock. Upgraded coal is used in coal gasification plants. When conducting industrial analysis on upgraded coal, it is necessary to perform sampling operations.

[0003] As disclosed in announcement number CN222258764U, a sampling shovel for upgraded coal includes a sampling shovel body and a connector disposed on the outside of the sampling shovel body. A connecting rod is disposed on the outside of the connector, an extension is disposed on the outside of the connecting rod, and a fixing member is disposed on the outside of the extension. The sampling shovel body includes a shovel body, a rod body is disposed on the outside of the shovel body, and a grip is fixedly connected to the outside of the rod body. The connector includes a fixing block fixedly connected to the outside of the shovel body, and an installation rod is rotatably connected inside the fixing block. This invention adjusts the length of the sampling shovel by moving the rod body inside the sleeve, causing the fixing rod to slide inside the through groove. The collar moves synchronously with the fixing rod. When the rod body reaches a suitable length, the screw on the collar is tightened into the screw hole, thereby fixing the rod body to the outside of the sleeve.

[0004] However, in the existing technology, the shovel used for sampling is open and lacks sealing measures, which makes it easy for the upgraded coal to fall during the sampling and transfer process, resulting in a reduction in sample volume. For example, the comparative patent listed above has this problem.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figures 1-7 .

[0039] To address the problem in existing technologies where the sampling shovel is open and lacks sealing measures, leading to easy spillage of upgraded coal during sampling and transfer, thus reducing sample volume, this solution proposes a rapid sampler for upgraded coal industrial analysis. The sampler comprises a first sampling cylinder 1, a second sampling cylinder 2, and a fixed long rod 3. The second sampling cylinder 2 is fixed to the left side of the first sampling cylinder 1 and has a hollow conical structure. A leak-proof mechanism is located at the right end of the first sampling cylinder 1. This mechanism includes a movable connecting sleeve 4 fitted onto the outer surface of the fixed long rod 3, a movable long rod 5 fixedly connected to the front and rear ends of the left side of the movable connecting sleeve 4, and a leak-proof cover plate 6 fixedly connected to the left end of the movable long rod 5. Simultaneously, the movable connecting sleeve 4, together with the movable long rod 5, moves the leak-proof cover plate 6 left and right outside the fixed long rod 3, and the leak-proof cover plate 6 is fitted against the right end of the first sampling cylinder 1.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, first, carry the sampler to the corresponding sampling position. Then, by pulling the movable connecting rod 14, the movable connecting rod 14 slides and extends at the right end of the fixed long rod 3 to adjust the length of the sampler. After adjusting to a suitable length, the movable connecting rod 14 and the fixed long rod 3 are limited by rotating the fixing bolt 16. Then, hold the fixed handle 15 with one hand and the movable connecting sleeve 4 with the other hand. The outer surface of the movable connecting sleeve 4 is provided with anti-slip rubber strips 7, which can play a good anti-slip role when pulling the anti-slip rubber strips 7. The lower end of the movable connecting sleeve 4 is fixedly connected to the limiting bracket 13. The limiting bracket 13 can prevent the hand from falling off the movable connecting sleeve 4 during the holding process. While holding the movable connecting sleeve 4, as Figure 4 , Figure 5 and Figure 6 As shown, when the movable limiting plate 12 is pressed down, the movable limiting plate 12 slides between itself and the auxiliary rod 10. The movable limiting plate 12 compresses the spring 11, causing the spring 11 to undergo elastic deformation. The movable limiting plate 12 moves downward in the auxiliary plate 9. At this time, the left side of the movable limiting plate 12 disengages from the fixed connecting plate 8, thereby releasing the limitation between the movable connecting sleeve 4 and the fixed long rod 3.

[0041] Then, pull the movable connecting sleeve 4 to the right. The movable connecting sleeve 4 slides on the outer surface of the fixed long rod 3. The movable connecting sleeve 4 drives the movable long rod 5 to slide between it and the fixed connecting plate 8, so that the movable long rod 5 drives the leak-proof cover 6 to move to the right. The leak-proof cover 6 slides on the left side of the fixed long rod 3. At this time, the leak-proof cover 6 is separated from the first sampling cylinder 1, opening the first sampling cylinder 1. Then, the sampler is inserted into the upgraded coal. The left side of the first sampling cylinder 1 is fixedly connected to the second sampling cylinder 2. The second sampling cylinder 2 is conical, making insertion faster, more convenient, and less strenuous. After insertion, the upgraded coal enters the cavity inside the first sampling cylinder 1 and the second sampling cylinder 2. Then, the sampler is pulled out from the upgraded coal. Then, move the movable connecting sleeve 4 to the left. The movable connecting sleeve 4, together with the movable long rod 5, drives the leak-proof cover 6 to engage on the left side of the first sampling cylinder 1, thereby sealing the first sampling cylinder 1 and preventing the upgraded coal from falling and reducing the sample volume.

[0042] Furthermore, the left side of the movable limiting plate 12 matches the upper right end of the fixed connecting plate 8. The movable connecting sleeve 4 drives the movable limiting plate 12 to move to the left and contact the fixed connecting plate 8. The fixed connecting plate 8 squeezes the movable limiting plate 12, causing the movable limiting plate 12 to move downward and squeeze the spring 11. The spring 11 undergoes elastic deformation, and the movable limiting plate 12 is inserted into the upper end of the fixed connecting plate 8. When the leak-proof cover 6 covers the right end of the first sampling cylinder 1, the movable connecting sleeve 4 is attached to the left end of the fixed connecting plate 8. At this time, the spring 11 recovers its elastic deformation, pushing the movable limiting plate 12 to move upward and engage with the fixed connecting plate 8. This facilitates the limiting of the movable connecting sleeve 4 and the fixed connecting plate 8, thereby fixing the leak-proof cover 6 to the right end of the first sampling cylinder 1. Then, the extracted upgraded coal sample is transferred and tested to achieve industrial analysis.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
