[0002] The dust sampler is a key instrument used to determine the concentration of airborne dust in industrial environments such as mines. It is widely used in industrial and mining enterprises, occupational safety, occupational health and environmental protection departments. It is of great significance for monitoring dust pollution, protecting workers' health and preventing occupational diseases such as pneumoconiosis. The dust sampler is equipped with a filter membrane that filters the air entering the instrument, so that dust particles are trapped on the surface of the filter membrane, and the quantity and properties of the collected dust particles are measured.

[0003] In existing technologies, a small amount of dust adheres to the inside of the pipe after sampling by the dust sampler. This dust will affect the results of the next sampling test. Furthermore, after collecting the dust, it is not convenient to remove the filter membrane from the inside of the pipe, thereby reducing the overall effectiveness of the sampler. Utility Model Content

[0004] The purpose of this invention is to solve the problem that a small amount of dust will adhere to the inside of the pipe after sampling by the above-mentioned dust sampler, which will affect the results of the next sampling test, and that it is inconvenient to remove the filter membrane from the inside of the pipe after collecting the dust. Therefore, a cleaning device for a mining dust sampler is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cleaning device for a mining dust sampler, comprising a sampler body, a suction pipe, and a connecting pipe. A limiting block is fixedly connected to one side of the suction pipe, and connecting blocks are fixedly connected to both the upper and lower ends of the suction pipe.

A hollow cylinder is fixedly connected to the top of the sampler body, and a positioning block is fixedly connected to one side of the limiting block.

[0006] Preferably, a fixing block is fixedly connected to the inner wall of the through hole, a sliding rod is fixedly installed on the side of the fixing block, and the scraper is slidably installed on the surface of the sliding rod.

[0007] Preferably, the diameter of the connecting tube is the same as the diameter of the suction tube, and the shape of the limiting block matches the shape of the placement groove.

[0008] Preferably, a pull rod is movably installed on the top of the hollow cylinder, and a first locking block is fixedly connected to the bottom of the pull rod. The bottom end of the first locking block is located inside the through hole, and a spring is movably sleeved on one end of the surface of the hollow cylinder.

[0009] Preferably, the interior of the connecting frame has a hollow structure, and the shape of the positioning block matches the internal shape of the connecting frame.

[0010] Preferably, a second locking block is movably installed at both the upper and lower ends of the positioning block, and a movable rod is movably connected to the bottom of the second locking block.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a cleaning device for a mining dust sampler, including a sampler body 1, a suction pipe 2, and a connecting pipe 3. A limiting block 21 is fixedly connected to one side of the suction pipe 2, and connecting blocks 22 are fixedly connected to both the upper and lower ends of the suction pipe 2. A connecting frame 31 is fixedly connected to both the upper and lower ends of the connecting pipe 3, and openings 301 are provided at both the upper and lower ends of the connecting pipe 3. A through hole 302 and a placement groove 303 are respectively provided on one side of the connecting pipe 3. A scraper 4 is provided inside the through hole 302, and a fixing rod 41 is fixedly connected to one side of the scraper 4. A filter membrane 5 is provided inside the placement groove 303. A hollow cylinder 6 is fixedly connected to the top of the sample body 1. A positioning block 7 is fixedly connected to one side of the limiting block 21. A fixing block 32 is fixedly connected to the inner wall of the through hole 302. A sliding rod 33 is fixedly installed on the side of the fixing block 32. A scraper 4 is slidably installed on the surface of the sliding rod 33. The diameter of the connecting pipe 3 is the same as the diameter of the suction pipe 2. The shape of the limiting block 21 matches the shape of the placement groove 303. A pull rod 61 is movably installed on the top of the hollow cylinder 6. A first locking block 62 is fixedly connected to the bottom of the pull rod 61. The bottom end of the first locking block 62 is located inside the through hole 302. A spring 63 is movably sleeved on one end of the surface of the hollow cylinder 6.

[0025] In this embodiment, the connecting tube 3 is connected to the suction tube 2, and the filter membrane 5 is placed inside the placement groove 303. At the same time, the limiting block 21 on the side of the suction tube 2 is located inside the placement groove 303, which will squeeze and limit the filter membrane 5 to prevent the filter membrane 5 from deviating. The sampler body 1 is started to suck the surrounding dust into the connecting tube 3 through the opening, so that the dust is filtered and adsorbed on one side of the filter membrane 5. When it is necessary to clean the inner wall of the connecting tube 3, the connecting tube 3 is disassembled and removed. Then, the pull rod 61 is lifted upward to make the first locking block 62 retract into the hollow cylinder 6. The fixing rod 41 is pushed to make the scraper 4 move inside the through hole 302 and scrape off the dust adhering to the inner wall of the through hole 302. The dust adhering to the surface of the slide rod 33 will be scraped off together when the scraper 4 slides, which facilitates the cleaning of the inside of the connecting tube 3.

[0026] Example 2

[0027] like Figures 1-5 As shown, the interior of the connecting frame 31 is a hollow structure. The shape of the positioning block 7 matches the internal shape of the connecting frame 31. The upper and lower ends of the positioning block 7 are movably mounted with second locking blocks 71. The bottom of the second locking block 71 is movably connected with a movable rod 72. The interior of the positioning block 7 is provided with a push rod 8. One end of the surface of the push rod 8 is movably connected to the bottom of the movable rod 72. A second spring 81 is fixedly connected to one side of the push rod 8. The second spring 81 is fixedly installed inside the positioning block 7.

[0028] In this embodiment, when the connecting tube 3 needs to be removed, the push rod 8 is pressed inward and the spring 81 is squeezed. When the push rod 8 moves inward, it will pull the movable rod 72. At the same time, the movable rod 72 will pull the second locking block 71 into the positioning block 7. At this time, the connecting tube 3 can be separated from the suction tube 2 by pulling on one side. Conversely, the connecting tube 3 is installed on the side of the suction tube 2. The connecting frame 31 is sleeved on the surface of the positioning block 7 and squeezes the second locking block 71. When the connecting frame 31 moves to the side of the second locking block 71, the second locking block 71 rebounds and limits the connecting frame 31, so that the connecting tube 3 is connected and fixed to the suction tube 2.

[0029] The working principle of this embodiment is as follows: The filter membrane 5 is placed inside the placement slot 303. The sampler body 1 is activated to draw the surrounding dust into the connecting tube 3 through the opening, so that the dust is filtered and adsorbed on one side of the filter membrane 5. Then, the push rod 8 is pressed inward and the spring 81 is squeezed. When the push rod 8 moves inward, it will pull the movable rod 72 and at the same time pull the second locking block 71 into the positioning block 7. At this time, the connecting tube 3 can be separated from the suction tube 2 by pulling one side, and the filter membrane 5 can be taken out. Then, the pull rod 61 is lifted upward to make the first locking block 62 retract into the hollow cylinder 6. The fixed rod 41 is pushed to make the scraper 4 move inside the through hole 302 and scrape off the dust adhering to the inner wall of the through hole 302, which facilitates the cleaning of the inside of the connecting tube 3.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
