Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically a dual-channel spiral full-section coal sampling device. Background Technology

[0002] A coal sampling device is a piece of equipment used to collect coal samples. It plays an important role in the coal production, transportation and quality testing process. Through this device, representative samples can be obtained from a large amount of coal according to certain standards and methods for subsequent testing and analysis, so as to accurately determine the key indicators such as coal quality and composition, and provide a scientific basis for the rational utilization and quality control of coal. The coal sampling device adopts a dual-channel spiral full-section design, mainly to ensure that the sampling process can fully cover the entire cross-section of the coal flow. This design, through two independent sampling channels and spiral motion, can effectively collect samples from different positions in the coal flow, thereby obtaining more representative samples. This not only improves the sampling accuracy but also reduces the deviation caused by incomplete sampling, ensuring that the samples can more accurately reflect the overall quality of the coal. While existing coal sampling devices achieve sampling functionality through a dual-channel design and reduce clogging to some extent, this design also brings new problems. Due to the complex internal structure of the sampling device, cleaning becomes difficult, which not only increases maintenance time and cost but also easily affects the accuracy of subsequent sampling. Therefore, a dual-channel spiral full-section coal sampling device is proposed to address the above problems. Utility Model Content

[0017] Please see Figures 1-8 This utility model provides a technical solution: A dual-channel spiral full-section coal sampling device includes a mobile vehicle 1 and a sampling support assembly 2. A sampling power assembly 4 is installed inside the sampling support assembly 2. A matching guide assembly 5 is fixedly connected to the top of the sampling power assembly 4. A transmission control assembly 3 is embedded inside the sampling power assembly 4. The sampling power assembly 4 includes a scraper seat 41. An extension cylinder 42 is fixedly connected to the top of the scraper seat 41. A second screw hole 43 is opened inside the extension cylinder 42. An inner cylinder 44 is fixedly connected to the bottom of the scraper seat 41. A spiral blade 45 is fixedly connected to the outer side of the 44. An internal threaded groove 46 is opened on the inner side of the inner cylinder 44. A rotating column 48 is fixedly connected to the top of the scraper seat 41. An internal turntable 54 is fixedly connected to the top of the rotating column 48. An opening 55 and a third screw hole 56 are opened on the inner side of the internal turntable 54. The internal turntable 54 is fixedly connected to the housing 51 by a second screw 53. The extension cylinder 42 is fixedly connected to the screw rod 32 by a first screw 47. The top of the screw rod 32 is fixedly connected to the end of the main shaft of the drive motor 23 by a transmission shaft 31.

[0018] As a further implementation of this solution, the sampling support assembly 2 includes a top plate 21. The rear end of the top plate 21 is fixedly connected to the mobile vehicle 1 via a rear seat 22. The top plate 21 is fixedly connected to the bottom plate 25 via a connecting column 24. A guide column 26 is fixedly connected between the top plate 21 and the bottom plate 25. Through the above arrangement, the fixed connection between the top plate 21 and the mobile vehicle 1 and the bottom plate 25, as well as the connection of the guide column 26, enhance the structural stability of the device, ensure the firmness and reliability of each component during the sampling process, facilitate the control of the up and down movement of the sampling support assembly 2, and provide driving force for the sampling work. As a further implementation of this solution, the guide post 26 is slidably connected to the inner side of the guide plate 52, the guide plate 52 is fixedly connected to the outer periphery of the housing 51, and the inner side of the housing 51 is rotatably connected to the built-in turntable 54 through a bearing. The second screw 53 is inserted into the housing 51 and can be threadedly connected to the third screw hole 56. Through the above settings, the sliding connection of the guide post 26 to the inner side of the guide plate 52 and the fixed connection between the guide plate 52 and the housing 51 can guide and limit the movement of the housing 51. The second screw 53 can control the cooperation relationship between the housing 51 and the built-in turntable 54. When the second screw 53 is removed, the built-in turntable 54 will not drive the housing 51 to rotate when it rotates, thereby improving the flexibility and convenience of use. As a further implementation of this solution, a sampling shell 27 is fixedly connected to the inner side of the base plate 25. An operation port 28 is provided near the upper end of the sampling shell 27. The operation port 28 is used to operate the first screw 47. The first screw 47 is threadedly connected to the inner side of the second screw hole 43 and the first screw hole 33. The first screw hole 33 is located inside the screw rod 32. Through the above arrangement, the fixed connection on the inner side of the sampling shell 27 and the operation position design of the operation port 28 facilitate the threaded connection and operation of the first screw 47. By installing the first screw 47, the fit relationship between the screw rod 32 and the inner cylinder 44 can be changed. After the first screw 47 fixes the first screw hole 33 and the inner cylinder 44, the coal sampling work can be realized through the transmission of the first screw hole 33. As a further implementation of this solution, a receiving opening 29 is provided on the inner side of the top plate 21. The top of the top plate 21 is fixedly connected to the housing of the drive motor 23. The main shaft of the drive motor 23 is located inside the receiving opening 29. Through the above arrangement, an installation position is provided for the main shaft of the drive motor 23, ensuring the stable rotation of the drive motor 23 and improving the power transmission efficiency and stability of the sampling device. As a further implementation of this scheme, the inner cylinder 44 is threadedly connected to the screw 32 through the internal thread groove 46. The inner cylinder 44, the spiral blade 45, and the scraper seat 41 are all embedded inside the sampling shell 27. The lower end of the scraper seat 41 is provided with an annular scraper. The scraper of the scraper seat 41 is slightly in contact with the inner side of the sampling shell 27. Through the above arrangement, the inner cylinder 44 is threadedly connected to the screw 32 through the internal thread groove 46, and the inner cylinder 44, the spiral blade 45, and the scraper seat 41 are embedded inside the sampling shell 27, ensuring the tight fit of the sampling components. The annular scraper at the lower end of the scraper seat 41 is slightly in contact with the inner side of the sampling shell 27, which can effectively scrape away the coal on the inner wall of the sampling shell 27, reduce the residue and pollution during the sampling process, and improve the representativeness and sampling accuracy of the sample. As a further implementation of this solution, the drive shaft 31 is embedded inside the port 55, and a gap is provided between the drive shaft 31 and the port 55. Through the above arrangement, the drive shaft 31 is embedded inside the port 55 and maintains an appropriate gap, ensuring the smooth rotation of the drive shaft 31 in the port 55, and improving the operating efficiency and stability of the sampling device.

[0019] Workflow: During sampling, the first screw 47 is operated through the operating port 28, threading the first screw 47 into the interior of the second screw hole 43 and the first screw hole 33, thus fixing the drive shaft 31 and the extension cylinder 42. Simultaneously, the second screw 53 installed on the housing 51 is removed. At this point, the housing 51 and the internal turntable 54 are in a rotational engagement relationship. The two drive motors 23 are started, driving the drive shaft 31 to rotate. The rotation of the drive shaft 31 within the through-hole 55 does not interfere with the internal turntable 54. The drive shaft 31 drives the screw 32 through... The first screw 47 fixes the extension cylinder 42, which in turn drives the extension cylinder 42, scraper 41, inner cylinder 44 and spiral blade 45 to rotate. The scraper 41 makes slight contact with the sampling shell 27. Although there will be slight friction, it will not affect the rotation of the scraper 41. The mobile vehicle 1 is equipped with a hydraulic suspension system, which can realize the lifting function of the platform. The device at the front end is controlled by the mobile vehicle 1 to move downward, and the coal layer is crushed by the spiral blade 45 and transported to the inside of the sampling shell 27 for storage. Then the device at the front end of the mobile vehicle 1 is raised upward, thereby realizing the function of dual-channel sampling of coal. When removing the coal stored inside the sampling shell 27 and cleaning the sampling shell 27, inner cylinder 44, and spiral blade 45, the first screw 47 is removed from the extension cylinder 42. The second screw 53 is then inserted into the sleeve 51 and fixed to the inner turntable 54. At this time, the sleeve 51 and the inner turntable 54 are in a fixed fit, while the screw 32 and the inner cylinder 44 are in a threaded fit. When the drive motor 23 is started, it drives the transmission shaft 31 and the screw 32 to rotate. The screw 32 is threadedly connected to the inner thread groove 46, causing the inner cylinder 44, spiral blade 45, scraper seat 41, extension cylinder 42, and rotating column 48 to move downwards simultaneously. The rotating column 48 drives the built-in turntable 54 to move downwards. The built-in turntable 54 drives the housing 51 and guide plate 52 to move. The guide plate 52 slides on the outside of the guide column 26 to guide. At this time, the spiral blade 45 will gradually move out of the sampling shell 27. At the same time, the scraper 41 will scrape the coal on the inner wall of the sampling shell 27 until the spiral blade 45 and the inner cylinder 44 are located outside the sampling shell 27 to collect the sampled coal. At the same time, the inner cylinder 44 and the spiral blade 45 located outside are extremely convenient for staff to observe and clean them, which facilitates the improvement of the cleanliness of the inner cylinder 44 and the spiral blade 45 and significantly improves the representativeness of the coal sampling.

[0020] 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.
