[0036] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0037] The following is for reference. Figures 1-6 This invention describes a coal powder sampling device 100 that is easy to assemble and disassemble according to an embodiment of the present invention.

[0038] like Figures 1-6 As shown, the coal powder sampling device 100 according to an embodiment of the present utility model includes: an operating handle 20 and a sampling tube 10. The sampling tube 10 is used to insert into the coal powder to take a sample, and the sampling tube 10 is detachably connected to the operating handle 20.

[0039] In this embodiment, the coal powder sampling device 100 is equipped with an operating handle 20 and a sampling tube 10. The sampling tube 10 is used to insert into the coal powder environment to take samples. When the operator performs coal powder sampling, the operator can operate the operating handle 20 to drive the sampling tube 10 to be inserted into the coal powder pipeline for sampling, so that the coal powder can enter the sampling tube 10. The operator then controls the sampling tube 10 to be pulled out of the coal powder pipeline, thereby completing the sampling operation.

[0040] The sampling tube 10 and the operating handle 20 are detachably connected. For example, the sampling tube 10 and the operating handle 20 can be connected by threaded connection, snap-fit ​​connection, plug-in connection, etc. The structure is simple, which makes it easy to assemble or disassemble the sampling tube 10 and the operating handle 20.

[0041] In this embodiment, the sampling tube 10 and the operating handle 20 are detachably connected, allowing the operating handle 20 to be used with sampling tubes 10 of different sizes and specifications for sampling operations. For example, when the coal powder sampling device 100 is sampling coal powder in another coal powder pipeline, the sampling environment changes, and the required size and specifications of the sampling tube 10 for sampling coal powder in the coal powder pipeline are different. At this time, the coal powder sampling device 100 can remove the original sampling tube 10 from the operating handle 20 and replace it with a sampling tube 10 of the required size and specifications for sampling, thereby adapting well to the coal powder sampling needs of different coal powder pipelines and sampling environments, and thus adapting well to diverse sampling needs.

[0042] After the coal powder sampling device 100 completes sampling, coal powder residue will accumulate in the sampling tube 10. When the coal powder sampling device 100 is used for a long time, the accumulated coal powder residue will cause blockage of the sampling tube 10, which will reduce the performance of the coal powder sampling device 100. Therefore, it needs to be cleaned. In related technologies, the sampling tube 10 and the operating handle 20 are integrated. The sampling tube 10 needs to be cleaned together with the operating handle 20. For example, when the sampling tube 10 is cleaned, the operating handle 20 is large or needs to be kept dry, which restricts the cleaning of the sampling tube 10. The movement and placement of the sampling tube 10 are greatly restricted, making the cleaning and maintenance of the sampling tube 10 inconvenient.

[0043] In this embodiment, the sampling tube 10 and the operating handle 20 are detachably connected, so that the sampling tube 10 can be removed from the operating handle 20 for separate cleaning. This allows for flexible and free movement, rotation, flipping, and placement during the cleaning process, making it easy to clean the sampling tube 10. This also makes it easier to clean the coal powder sampling device 100 after use, thus making the maintenance of the coal powder sampling device 100 more convenient.

[0044] The coal powder sampling device 100 according to the present invention is easy to disassemble and assemble. By setting a sampling tube 10 and an operating handle 20, the sampling tube 10 and the operating handle 20 are detachably connected. The structure is simple, which allows the coal powder sampling device 100 to easily replace the sampling tube 10 according to the sampling needs. After use, the sampling tube 10 can be easily cleaned, thus well meeting diverse sampling needs and making the maintenance of the coal powder sampling device 100 more convenient.

[0045] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, one end of the sampling tube 10 may be provided with a first connecting part 111, and the operating handle 20 is provided with a second connecting part 21. One of the first connecting part 111 and the second connecting part 21 is provided with a threaded groove 211 and the other is provided with a threaded post 1111. The sampling tube 10 and the operating handle 20 are threadedly connected by the threaded post 1111 and the threaded groove 211.

[0046] In this embodiment, the sampling tube 10 and the operating handle 20 are connected by a first connecting part 111 and a second connecting part 21. When the first connecting part 111 is provided with a threaded groove 211, the second connecting part 21 is provided with a threaded post 1111, or when the first connecting part 111 is provided with a threaded post 1111, the second connecting part 21 is provided with a threaded groove 211. When the sampling tube 10 and the operating handle 20 are assembled, the threaded post 1111 and the threaded groove 211 are threadedly connected, so that the first connecting part 111 and the second connecting part 21 are connected, thereby fixing the sampling tube 10 to the operating handle 20. When the sampling tube 10 and the operating handle 20 are disassembled, the threaded post 1111 is unscrewed from the threaded groove 211, so that the sampling tube 10 can be removed from the operating handle 20 for cleaning or replacement.

[0047] In this embodiment, a first connecting part 111 is provided at one end of the sampling tube 10. The first connecting part 111 can seal one end of the sampling tube 10 so that the coal powder sampled in the sampling tube 10 can be stored in the sampling tube 10.

[0048] In this embodiment, the sampling tube 10 and the operating handle 20 are connected by a first connecting part 111 and a second connecting part 21. The sampling tube 10 and the operating handle 20 are connected by a threaded post 1111 and a threaded groove 211. The structure is simple, which allows the sampling tube 10 and the operating handle 20 to be firmly connected. The sampling tube 10 and the operating handle 20 can be easily disassembled and assembled, thus well meeting the disassembly and assembly needs of the coal powder sampling device 100.

[0049] Optionally, the second connecting part 21 can be located at the middle of one side of the outer wall of the operating handle 20, and a threaded groove 211 can be opened in the middle of the end face of the second connecting part 21, and a threaded post 1111 is provided in the middle of the end face of the first connecting part 111.

[0050] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 As shown, the sampling tube 10 may include: a first tube segment 11 and a second tube segment 12, wherein the first tube segment 11 is along a first direction (e.g., Figure 1 The second pipe segment 12 extends in the front-back direction shown and is detachably connected to the operating handle 20; the second pipe segment 12 is connected to and communicates with the first pipe segment 11, and the second pipe segment 12 is movable relative to the first pipe segment 11 in the first direction.

[0051] In this embodiment, the second pipe segment 12 is connected to and communicates with the first pipe segment 11. The second pipe segment 12 is movable relative to the first pipe segment 11 along the first direction. The sampling tube 10 can then form a telescopic structure by moving the second pipe segment 12 relative to the first pipe segment 11 along the first direction. This allows for convenient adjustment of the length of the sampling tube 10 in the first direction, enabling flexible and convenient adjustment of its length according to sampling needs. This allows the coal powder sampling device 100 to flexibly adjust the sampling depth according to sampling requirements, ensuring the representativeness of the coal powder sample. For example, if a coal powder pipeline requires a longer sampling tube 10 to reach a preset sampling point within the pipeline, the length of the sampling tube 10 can be adjusted by moving the second pipe segment 12 to meet the sampling needs. This reduces the need for disassembling and replacing the sampling tube 10, allowing the coal powder sampling device 100 to better adapt to diverse sampling requirements.

[0052] Optionally, the sampling tube 10 may be equipped with a self-locking structure, so that the second tube segment 12 can self-lock after moving into place relative to the first tube segment 11 in the first direction as needed, thereby maintaining a stable length dimension of the sampling tube 10 and meeting the needs of sampling operations. For example, the first tube segment 11 may be provided with multiple self-locking grooves in the first direction, and the second tube segment 12 may be equipped with a self-locking slider 61 and a self-locking spring, so that after the second tube segment 12 moves into place, the second tube segment 12 can be inserted into the self-locking groove through the self-locking slider 61 and locked by the self-locking spring, thereby achieving self-locking with the first tube segment 11 and meeting the usage requirements of the sampling tube 10. The self-locking structure of the sampling tube 10 can be flexibly set as needed, and no specific limitation is made here, as long as it meets the usage requirements.

[0053] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, one end of the sampling tube 10 can be detachably connected to the operating handle 20, and the other end of the sampling tube 10 is formed as a sampling end. The coal powder sampling device 100 also includes a scraper assembly 30, which is detachably disposed at the sampling end. The scraper assembly 30 is configured to rotate with the rotation of the sampling tube 10 to clean the coal powder.

[0054] In this embodiment, the other end of the sampling tube 10 is formed as a sampling end. That is, when the coal powder sampling device 100 takes a sample, the other end of the sampling tube 10 extends into the coal powder in the coal powder pipe section to take a sample. The coal powder can enter the sampling tube 10 through the opening of the sampling end of the sampling tube 10, thereby realizing sampling. The scraper assembly 30 is detachably provided at the sampling end and is configured to rotate with the rotation of the sampling tube 10 to clean the coal powder.

[0055] During the process of the sampling tube 10 being inserted into the coal powder, the operator can rotate the sampling tube 10 by reciprocatingly turning the operating handle 20, thereby rotating the scraper assembly 30. The scraper assembly 30 can scrape and disperse the coal powder around the sampling tube 10 at the sampling end, reducing the pressure formed by the coal powder covering and squeezing the sampling tube 10. This makes it easier for the sampling tube 10 to be inserted into the coal powder for sampling, reducing manpower and making coal powder sampling more convenient and easier to a certain extent. When the sampling tube 10 is withdrawn from the coal powder pipeline after sampling, the scraper assembly 30 can clean and scrape off the coal powder at the sampling port of the coal powder pipeline, thereby preventing coal powder from being carried on the outer wall of the sampling tube 10 and spilling out of the coal powder pipeline. This can reduce the amount of coal powder cleaning work in the sampling process and make the sampling operation of the coal powder sampling device 100 more convenient and easier.

[0056] In this embodiment, the scraper assembly 30 is detachably connected to the sampling tube 10, so that when the sampling tube 10 is replaced or cleaned, the scraper assembly 30 can be easily detached from the sampling tube 10, making the replacement or cleaning of the sampling tube 10 more convenient.

[0057] In one embodiment of this utility model, such as Figure 3 As shown, the scraper assembly 30 may include: a fixing member 33, a connecting member 32, and a scraper 31. The fixing member 33 is sleeved on the sampling end. The connecting member 32 is connected to the fixing member 33 and the scraper 31. The scraper 31 extends along the first direction and is located on the radial outer side of the sampling tube 10. There are multiple scrapers 31, which are arranged at intervals along the circumference of the sampling tube 10. There are multiple connecting members 32, which are arranged one-to-one with the multiple scrapers 31.

[0058] In this embodiment, the scraper assembly 30 includes a fixing member 33, a connecting member 32, and a scraper 31. The fixing member 33 is sleeved on the sampling end, and the connecting plate is connected to the fixing member 33 and the scraper 31. The structure is simple and facilitates the assembly and fixation of the scraper assembly 30 on the sampling tube 10. The scraper 31 extends along the first direction and is located on the radial outer side of the sampling tube 10. This allows the scraper 31 to clean the coal powder in a large area around the sampling tube 10 in the extension direction of the sampling tube 10 when it rotates with the sampling tube 10, thus well meeting the usage requirements. Multiple scrapers 31 are provided and arranged at intervals along the circumference of the sampling tube 10, which can improve the cleaning effect and efficiency of the scraper 31 on the coal powder to a certain extent. Multiple connecting members 32 are arranged one-to-one with multiple scrapers 31. The structure is simple and meets the connection requirements between the scraper 31 and the fixing member 33.

[0059] For example, the number of scrapers 31 can be two, three, four, etc., and the number of connectors 32 can be correspondingly set to two, three, four, etc. Optionally, the fixing member 33 can be a fixing ring, and the scraper 31 can be a plastic part.

[0060] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the coal powder sampling device 100 may also include a first anti-slip element 70, which is detachably sleeved on the sampling tube 10 and located at the end of the sampling tube 10 connected to the operating handle 20.

[0061] In this embodiment, the first anti-slip component 70 is detachably sleeved on the sampling tube 10 and located at the end of the sampling tube 10 connected to the operating handle 20. The structure is simple and allows the operator to hold the sampling tube 10 stably by holding the first anti-slip component 70 when assembling or disassembling the sampling tube 10 with the operating handle 20, making the coal powder sampling device 100 easier and more convenient to assemble and disassemble.

[0062] In this embodiment, the first anti-slip component 70 is detachably sleeved and connected to the sampling tube 10, which facilitates the replacement of the first anti-slip component 70 and the separate cleaning of the sampling tube 10. Optionally, the first anti-slip component 70 can be a rubber sleeve, and the surface of the first anti-slip component 70 can be provided with anti-slip texture, for example, forming a plurality of protrusions arranged at intervals along the first direction, the protrusions extending in a ring along the circumference of the first anti-slip component 70, that is, the circumference of the sampling tube 10.

[0063] In some embodiments of this utility model, reference is made to Figure 2 , Figure 4 and Figure 5 As shown, the operating handle 20 is along the second direction (e.g.) Figure 2The coal powder sampling device 100 may further include: a display 50 and a handheld component 40. One end of the display 50 is rotatably connected to one end of the operating handle 20 in the second direction. The other end of the display 50 is provided with a docking groove 51 and extends obliquely toward the other end of the operating handle 20 away from the sampling tube 10. The handheld component 40 is located on the side of the operating handle 20 away from the sampling tube 10. One end of the handheld component 40 is connected to the operating handle 20. The other end of the handheld component 40 is provided with a docking block 41. One of the docking groove 51 and the docking block 41 is provided with a slot 511 and the other is provided with a block 411. The display 50 and the handheld component 40 extend into the docking groove 51 through the docking block 41 and the slot 511 and the block 411 are engaged and connected.

[0064] In this embodiment, the second direction intersects the axis of the sampling tube 10, that is, the second direction intersects the first direction. This is intended to show that the second direction and the axis of the sampling tube 10 can be arranged perpendicularly or only intersecting and not perpendicularly.

[0065] In this embodiment, the coal powder sampling device 100 is also provided with a display 50 and a handheld device 40. The display 50 can be used to display sampling information, such as the sampling time and sampling amount of coal powder. For example, a sheet-like capacitive sensor can be provided in the sampling tube 10 to measure the coal powder concentration and be electrically connected to the display 50, so as to obtain the amount of coal powder in the sampling tube 10 according to the coal powder concentration in the sampling tube 10, and obtain the sampling amount of coal powder.

[0066] One end of the display 50 is rotatably connected to one end of the operating handle 20 in the second direction, and the other end of the display 50 extends at an angle away from the sampling tube 10 toward the other end of the operating handle 20. In other words, the display 50 is located on the side of the operating handle 20 away from the sampling tube 10, which makes it easier for the operator to view the screen of the display 50. The display 50 can also be rotated to adjust the angle, making it easier for the operator to view.

[0067] One end of the handheld component 40 is connected to the operating handle 20, allowing the operator to hold the handheld component 40 to operate and move the coal powder sampling device 100, thus facilitating the use of the coal powder sampling device 100. The other end of the handheld component 40 is provided with a docking block 41, and the other end of the display 50 is provided with a docking groove 51. When the coal powder sampling device 100 is in use, the display 50 can be rotated to insert the docking block 41 into the docking groove 51, so that the handheld component 40 can support and fix the display 50. Furthermore, one of the docking groove 51 and the docking block 41 is provided with a slot 511 and the other is provided with a block 411. For example, when the docking groove 51 is provided with a slot 511, the docking block 41 is provided with a block 411. When the docking groove 51 is provided with a block 411, the docking block 41 is provided with a slot 511. After the docking block 41 is inserted into the docking groove 51, the docking block 41 can be connected and fixed to the display 50 by the snap-fit ​​connection of the block 411 and the slot 511, so that the display 50 can be stably and reliably connected to the handheld component 40. In this way, during the sampling or movement of the coal powder sampling device 100, the display 50 can be stably and reliably fixed on the operating handle 20 and the handheld component 40.

[0068] In some embodiments of this utility model, reference is made to Figure 2 and Figure 4 As shown, the operating handle 20 extends along a second direction, which intersects the axial direction of the sampling tube 10. The other end of the operating handle 20 in the second direction may be provided with a groove 201. The groove 201 extends along a first direction and is open at one end. The coal powder sampling device 100 also includes a support assembly 60, which is detachably connected to the operating handle 20. The support assembly 60 may include a slider 61, a support column 62, and a base 63. The slider 61 is movably disposed in the groove 201 along the first direction. The support column 62 extends along the second direction and is connected at both ends to the slider 61 and the base 63, respectively. The base 63 is provided with a second anti-slip member 64 on the side of the second direction away from the operating handle 20.

[0069] In this embodiment, the operating handle 20 is provided with a slide groove 201 at the other end in the second direction. The slide groove 201 extends along the first direction and is open at one end. The slider 61 of the support assembly 60 is movably disposed in the slide groove 201 along the first direction. The support column 62 extends along the second direction and is connected to the slider 61 and the base 63 at both ends respectively. Specifically, the side of the operating handle 20 facing the base 63 can be provided with a clearance groove. The clearance groove is connected to the slide groove 201 so that the support column 62 can pass through the clearance groove and extend into the slide groove 201 to connect with the slider 61.

[0070] In this embodiment, a support component 60 is provided to facilitate the storage of the coal powder sampling device 100. When the coal powder sampling device 100 has completed sampling or cleaning and needs to be stored, the support component 60 can be installed on the operating handle 20. The slider 61 of the support component 60 slides into the groove 201 from the opening of the groove 201 along the first direction and moves into place. This allows the support component 60 to support the operating handle 20, the display 50, and the handheld part 40 when the coal powder sampling device 100 is placed, thereby preventing the operating handle 20 from directly contacting and bumping with the platform surface of the placement platform. At the same time, the base 63 is also provided with a second anti-slip part 64, which allows the coal powder sampling device 100 to be placed stably even when the platform surface of the placement platform is wet or has a certain slope. Thus, the coal powder sampling device 100 can be placed and stored stably and conveniently under different storage conditions. Optionally, the center of the base 63 may be recessed toward the operating handle 20, and the side of the base 63 opposite to the operating handle 20 may form two support surfaces. A second anti-slip element 64 may be attached to the support surface, and the second anti-slip element 64 may be an anti-slip rubber pad.

[0071] In some embodiments of this utility model, such as Figure 1 As shown, a radiator 80 can be provided on the operating handle 20. This can prevent the operating handle 20 from overheating when the coal powder sampling device 100 has a long sampling time, making the operator more comfortable to use.

[0072] In some embodiments of this utility model, such as Figure 6 As shown, in the radial direction of the sampling tube 10, the sampling tube 10 may include a first protective layer 101, an intermediate layer 102 and a second protective layer 103 arranged in layers from the inside out. The first protective layer 101 is a corrosion-resistant layer and the second protective layer 103 is a wear-resistant layer.

[0073] In this embodiment, the sampling tube 10 adopts a multi-layer structure. From the inside out, the sampling tube 10 consists of a first protective layer 101, an intermediate layer 102, and a second protective layer 103. The first protective layer 101 forms the inner wall of the sampling tube 10, and the second protective layer 103 forms the outer wall of the sampling tube 10. In this embodiment, the first protective layer 101 is set as a corrosion-resistant layer, which can effectively resist corrosive substances in coal powder and protect the inner wall of the sampling tube 10 from damage. The second protective layer 103 is set as a wear-resistant layer, which can effectively reduce the probability of wear caused by the flow of coal powder during the sampling process, so that the sampling tube 10 can have good wear-resistant and corrosion-resistant properties, thereby extending the service life of the sampling tube 10.

[0074] In some embodiments of this utility model, reference is made to Figure 1As shown, one end of the sampling tube 10 is detachably connected to the operating handle 20, and the other end of the sampling tube 10 is provided with a sampling head. Along the axial direction of the sampling tube 10, the outer diameter of the sampling head gradually decreases away from the sampling tube 10. This reduces the resistance encountered when the sampling tube 10 is inserted, making it easier for the sampling tube 10 to be inserted into the coal powder for sampling.

[0075] The following will refer to Figures 1-6 This invention describes a coal powder sampling device 100 that is easy to assemble and disassemble according to a specific embodiment of the present invention.

[0076] like Figures 1-6 As shown, the coal powder sampling device 100 includes a sampling tube 10, an operating handle 20, a display 50, a handheld component 40, a support assembly 60, a scraper assembly 30, and a first anti-slip component 70.

[0077] The sampling tube 10 is a telescopic design. The sampling tube 10 includes a first tube section 11 and a second tube section 12. The second tube section 12 extends into the first tube section 11 and is movable relative to the first tube section 11 in a first direction to achieve telescopic extension. The end of the second tube section 12 opposite to the first tube section 11 is formed as a sampling end and is provided with a sampling head. The sampling head and the second tube section 12 are integral parts. The sampling head forms a sampling port that communicates with the second tube section 12 and the first tube section 11.

[0078] One end of the first pipe section 11 has a first connecting part 111, the first connecting part 111 is provided with a threaded post 1111, the operating handle 20 is provided with a second connecting part 21, the second connecting part 21 is provided with a threaded groove 211, the first pipe section 11 is threadedly connected by the threaded post 1111 of the first connecting part 111 and the threaded groove 211 on the second connecting part 21 of the operating handle 20.

[0079] One end of the display 50 is rotatably connected to the operating handle 20 on one side in the second direction. The other end of the display 50 is provided with a docking groove 51. The inner wall of the docking groove 51 is provided with a slot 511. One end of the handheld part 40 is connected to the operating handle 20. The other end of the handheld part 40 is provided with a docking block 41. The docking block 41 extends into the docking groove 51. The docking block 41 is provided with a slot 411. The slot 411 is engaged with the slot 511.

[0080] The support assembly 60 includes a slider 61, a support column 62, and a base 63. The support column 62 is connected to the slider 61 and the base. The slider 61 is located in the groove 201 of the operating handle 20 and is movable in a first direction. The base 63 is provided with a second anti-slip element 64, which is an anti-slip rubber pad. The scraper assembly 30 includes a fixing element 33, a connecting element 32, and scrapers 31. The fixing element 33 is a fixing ring and is sleeved on the sampling end of the second pipe section 12. There are two scrapers 31. The connecting element 32 is a connecting rod and is arranged one-to-one with the scrapers 31. The scrapers 31 are fixed to the fixing element 33 through the connecting element 32. The first anti-slip element 70 is a rubber sleeve and is sleeved on the end of the first pipe section 11 near the operator's hand.

[0081] When the operator operates the coal powder sampling device 100 for sampling, the operator checks whether the sampling tube 10, operating handle 20, and other components are intact. After ensuring that the display 50 is working properly, the operator can hold the handpiece 40 to pick up the coal powder sampling device 100. The support component 60 disengages from the chute 201. The operator can adjust the length of the sampling tube 10 according to the sampling needs. After length adjustment, the operator can use the operating handle 20 to control the sampling tube 10 to extend into the coal powder pipeline from the sampling port. During the extension process, the operator can rotate the sampling tube 10 and gradually extend it into the coal powder. The coal powder enters the sampling tube 10 and is collected as the sampling tube 10 gradually extends in. After sampling is completed, the operator can use the operating handle 20 to remove the sampling tube 10 from the coal powder pipeline. During the removal process, the operator can rotate the sampling tube 10 to shake off the coal powder on the outer wall of the sampling tube 10. The scraper assembly 30 cleans the coal powder at the sampling port through the scraper 31. After sampling is completed, the operator can view the sampling time and coal powder sampling amount on the monitor 50 and record the necessary data.

[0082] After the coal powder sampling device 100 completes sampling, the operator can install the support component 60 onto the operating handle 20, allowing the coal powder sampling device 100 to be supported and placed using the support component 60. Alternatively, in specific sampling operations where a good support platform is available at the sampling site, the operator can also use the support component 60 to set up the coal powder sampling device 100 on the support platform for sampling. This reduces the physical strain on the operator during sampling, making the sampling operation easier. Furthermore, in conjunction with the second anti-slip element 64 on the base 63, it makes the operator's control of the sampling tube 10 via the operating handle 20 more stable during sampling.

[0083] When the coal powder sampling device 100 needs to be cleaned, the operator can detach the sampling tube 10 from the operating handle 20 and remove the first anti-slip part 70 and the scraper assembly 30 from the sampling tube 10, so that the sampling tube 10 and the scraper assembly 30 can be cleaned or cleaned separately.

[0084] This embodiment features a sampling tube 10 and an operating handle 20, which are detachably connected. The simple structure allows for easy disassembly and assembly of the sampling tube 10 and the operating handle 20 in the coal powder sampling device 100. The sampling tube 10 can be easily replaced according to sampling needs, and it can be easily cleaned after use, greatly improving the ease of maintenance of the coal powder sampling device 100. This effectively meets diverse sampling needs and allows for convenient maintenance of the coal powder sampling device 100.
