[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0021] like Figures 1 to 3 As shown, the coal quality testing sampler 100 of the embodiment of the utility model comprises a crushing box 1, a lifting member 2, a first rotating shaft 3 and a conical hammer 4. The crushing box 1 comprises a connected straight section 101 and a conical section 102 from top to bottom, the cross-sectional area of ​​the conical section 102 decreases from top to bottom, the straight section 101 has a coal inlet 1011, and the bottom end of the conical section 102 has a coal outlet 1021. The lifting member 2 is arranged in the straight section 101 in an adjustable position in the up and down direction, the first rotating shaft 3 is arranged in the crushing box 1 and extends in the vertical direction, and the top end of the first rotating shaft 3 is rotatably connected to the lifting member 2. The conical hammer 4 is arranged in the crushing box 1 and is coaxially connected to the first rotating shaft 3, at least a part of the conical hammer 4 is located in the conical section 102, the cross-sectional area of ​​the conical hammer 4 decreases from top to bottom, and the conical hammer 4 is used to crush the coal flowing between the conical hammer 4 and the conical section 102.

[0022] During use, the coal quality testing sampler 100 of the embodiment of the utility model delivers large coal particles into the crushing box 1 through the coal inlet 1011. By adjusting the position of the lifting member 2 in the vertical direction, the position of the conical hammer 4 in the height direction can be changed to adjust the distance between the conical hammer 4 and the inner wall surface of the conical section 102, so that the coal can be effectively crushed into the required particle size, thereby facilitating subsequent testing and analysis. The adjustable position function of the lifting member 2 can be flexibly adjusted as needed to meet the analysis requirements of coal samples of different specifications and properties.

[0023] When the size of the crushed coal particles is smaller than the distance between the conical hammer 4 and the inner wall of the conical section 102, the coal particles can slide down from the inner wall of the conical section 102 and be discharged from the coal outlet 1021. Therefore, the coal quality testing sampler 100 of the embodiment of the utility model can quickly collect coal with the required particle size according to the detection requirements, thereby improving the accuracy and efficiency of coal testing sampling.

[0024] In some embodiments, the coal quality testing sampler 100 of the utility model embodiment further includes a first motor 5, which is disposed outside the crushing box 1 and connected to the top end of the first rotating shaft 3 to drive the first rotating shaft 3 to rotate.

[0025] This design makes the operation of the sampler more flexible and efficient, because the crushing force and speed of the conical hammer 4 can be adjusted by controlling the rotation speed and torque of the first motor 5, thereby better controlling the degree of coal crushing. In addition, this design also reduces the mechanical friction and wear that may exist inside the sampler, and improves the stability and service life of the sampler.

[0026] In some embodiments, the generatrix of the conical section 102 is parallel to the generatrix of the conical hammer 4. This design not only allows the coal to be crushed more evenly when passing through the conical hammer 4, but also helps to improve the coal crushing efficiency, and can also ensure that the coal is better distributed and processed during the crushing process, so that it is easier to carry out quality testing sampling, so as to improve the accuracy and reliability of the sampler, making it more practical and efficient in industrial practice.

[0027] In some embodiments, a plurality of spaced crushing teeth 6 are provided on the outer circumference of the conical hammer 4. By providing a plurality of crushing teeth 6 on the outer circumference of the conical hammer 4, the contact area between the coal and the conical hammer 4 can be increased, thereby better dispersing and crushing the coal. At the same time, the design and number of the crushing teeth 6 can be adjusted according to the characteristics and requirements of the coal to adapt to different types and properties of coal.

[0028] In some embodiments, a plurality of semicircular protrusions 7 are arranged at intervals on the inner wall surface of the conical section 102. These semicircular protrusions 7 can increase the contact area between the coal and the inner wall surface of the conical section 102, thereby better dispersing and crushing the coal. In addition, these semicircular protrusions 7 can also help control the flow direction of the coal, so that it flows more evenly through the conical section 102 and the conical hammer 4, thereby improving the performance and efficiency of the sampler.

[0029] In some embodiments, the box wall of the straight section 101 has a chute 1012 extending in the up-down direction, and the coal quality testing sampler 100 also includes a sliding member 8, which is connected to the lifting member 2 and extends to the outside of the straight section 101 through the chute 1012, and the sliding member 8 can slidably cooperate with the chute 1012 in the up-down direction. The lifting member 2 is controlled to move up and down in the straight section 101 by controlling the sliding member 8, thereby controlling the position and depth of the conical hammer 4 to better process the coal sample. The cooperation between the sliding member 8 and the chute 1012 can ensure the stable movement of the lifting member 2, thereby improving the reliability and efficiency of the sampler.

[0030] In some embodiments, the coal quality testing sampler 100 of the utility model embodiment further includes a mounting frame 9, a lead screw 10 and a lead screw nut 11. The mounting frame 9 is arranged outside the crushing box 1, the lead screw 10 is arranged on the mounting frame 9 along the vertical direction and is rotatably connected to the mounting frame 9, and the lead screw nut 11 is arranged on the sliding member 8 and is spirally matched with the lead screw 10.

[0031] The coal quality testing sampler 100 of the embodiment of the utility model makes the operation of the coal quality testing sampler 100 more flexible and efficient through the design of the mounting frame 9, the lead screw 10 and the lead screw nut 11. The cooperation of the lead screw 10 and the lead screw nut 11 can realize the precise movement of the sliding member 8 in the vertical direction, thereby accurately controlling the position and depth of the conical hammer 4 to ensure that the coal is evenly and effectively crushed. In addition, the setting of the mounting frame 9 makes the structure of the entire sampler more stable and firm, and improves the reliability and durability of the equipment.

[0032] In some embodiments, the coal quality testing sampler 100 of the utility model embodiment further includes a rotating handle 12, which is connected to the lead screw 10 for rotating the lead screw 10. By rotating the handle 12, the operator can conveniently control the rotation of the lead screw 10, thereby controlling the up and down movement of the sliding member 8 on the lead screw 10, and adjusting the position and depth of the conical hammer 4. This design makes the operation more convenient and flexible, and improves the operability and applicability of the sampler.

[0033] In some embodiments, the coal quality testing sampler 100 of the utility model embodiment further includes a collection tube 13, a connecting pipe 14, a spiral dragon 15 and a second motor 16. The collection tube 13 has a coal mining port 1301 at one end, a coal delivery port 1302 is provided on the tube wall of the collection tube 13, and the coal delivery port 1302 is connected to the coal inlet 1011 through the connecting pipe 14. The spiral dragon 15 is arranged in the collection tube 13 and is rotatably connected to the collection tube 13. The second motor 16 is connected to the spiral dragon 15 to drive the spiral dragon 15 to rotate.

[0034] Specifically, during use, the second motor 16 drives the dragon to rotate, and the coal sampling port 1301 at one end of the collection tube 13 transports the coal collected from the coal source through the spiral dragon 15 and enters the connecting pipe 14 through the coal delivery port 1302, and then enters the crushing box 1 through the connecting pipe 14. This design can improve the automation and operation convenience of the sampler, and at the same time ensure the representativeness of the coal sample and the accuracy of the test. By integrating these components, the sampler can realize the collection, crushing, transportation and distribution of coal samples, providing comprehensive support for coal quality testing.
