[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-4 As shown, a dust suppression device for coal mining includes two water pipes 1 and two outer tubes 3. A plurality of nozzles 2 are disposed outside the two water pipes 1. A protective structure 6 is disposed outside the two water pipes 1.

[0025] The protection structure 6 includes two protection boxes 7, which are respectively arranged on the outside of the two water pipes 1. A storage rack 8 is arranged in the middle of the rear of the protection box 7, and a motor 9 is arranged at one end of the storage rack 8. The output shaft of the motor 9 is located on the inner side of the storage rack 8 and is rotatably provided with a screw rod 10. A slider 11 is slidably provided on the outside of the screw rod 10. A group of connecting arms 12 are rotatably provided on the top and bottom of the two sliders 11, and one end of the four groups of connecting arms 12 is rotatably connected to the middle position of the top of the four opening and closing covers 13.

[0026] An external water source is connected to the water inlet 4. When dust reduction work is needed, the motor 9 is started, so that the motor 9 acts on the screw rod 10 to rotate, and then the slider 11 slides on the outside of the screw rod 10. When the slider 11 slides from the end of the screw rod 10 away from the motor 9 to the other end of the screw rod 10 close to the motor 9, the motor 9 can be turned off to spray and reduce dust. During the process, the slider 11 carries the adjusting cylinder 5 to slide on the inner side of the outer cylinder 3 toward the direction of the motor 9, so that the outer cylinder 3 is released from the restriction to pass water. At the same time, the slider 11 acts on the opening and closing cover 13 through the connecting arm 12, so that the opening and closing cover 13 rotates open to expose the nozzle 2 inside the protective box 7 for spraying.

[0027] In this embodiment, the two ends of the four opening and closing covers 13 are respectively rotatably set on the top and bottom of the two protection boxes 7, the opening and closing covers 13 are adaptably matched with the protection boxes 7, the front of the two protection boxes 7 are opened with square holes, and one end of several nozzles 2 is set on the inner side of the square hole.

[0028] The opening and closing cover 13 protects the nozzle 2 , and the protection box 7 protects the water pipe 1 .

[0029] In this embodiment, one end of the two water pipes 1 passes through one side of the outside of the two outer cylinders 3 respectively, and the other side of the outside of the two outer cylinders 3 is provided with a water inlet 4, and the two water inlets 4 pass through one end of the protective box 7.

[0030] Dust reduction can be carried out by connecting an external water source at the water inlet 4.

[0031] In this embodiment, the two outer cylinders 3 are respectively arranged at one end of the inner side of the protection box 7, and the inner sides of the two outer cylinders 3 are movably provided with adjustment cylinders 5. The two adjustment cylinders 5 respectively penetrate the rear side of the two protection boxes 7, and one end of the two adjustment cylinders 5 is respectively connected to one end of the two sliders 11.

[0032] The regulating cylinder 5 has a limiting effect on the opening and closing of the outer cylinder 3 .

[0033] In this embodiment, an adjustment structure 14 is arranged between the tops of the two protection boxes 7. The adjustment structure 14 includes four fixed plates 15. The four fixed plates 15 are respectively arranged at the middle positions of the tops of the two protection boxes 7. A T-shaped tube 16 is rotatably arranged between the two fixed plates 15. The two T-shaped tubes 16 are respectively symmetrically slidably arranged on the outside of the two threaded rods 17.

[0034] Fix the mounting frame 18 at the required location with bolts, and rotate the threaded rod 17 according to the required working width, so that the threaded rod 17 acts on the T-tube 16 to slide outside the threaded rod 17. When the appropriate length is adjusted, stop rotating the threaded rod 17, and then rotate the screws of the fixing plate 15 according to the required angle to adjust the working angle of the protective structure 6. After the adjustment is completed, fix the screws to complete the adjustment and installation work.

[0035] In this embodiment, two threaded rods 17 are rotatably disposed at two sides of the bottom of the mounting frame 18 , and four reserved holes are opened at the top of the mounting frame 18 .

[0036] The threaded rod 17 allows the T-tube 16 to be slidably adjusted in length.

[0037] In this embodiment, the threaded rods 17 are all adaptable to the T-tubes 16 , and the outer tubes 3 are all adaptable to the adjustment tubes 5 .

[0038] The threaded rod 17 cooperates with the T-shaped tube 16 to adjust the working length of the two protective structures 6 in both directions.

[0039] It should be noted that the utility model is a dust suppression device for coal mining. When in use, it is placed at a site where it needs to work, and an external water source is connected at the water inlet 4 to enable it to reach the working operating conditions;

[0040] During the process, an external water source is connected at the water inlet 4. When dust reduction work is required, the motor 9 is started, so that the motor 9 acts on the screw rod 10 to rotate, and then the slider 11 slides outside the screw rod 10. When the slider 11 slides from the end of the screw rod 10 away from the motor 9 to the other end of the screw rod 10 close to the motor 9, the motor 9 can be turned off to spray and reduce dust. During the process, the slider 11 slides with the adjustment cylinder 5 on the inner side of the outer cylinder 3 toward the direction of the motor 9, so that the outer cylinder 3 is released from the restriction to pass water. At the same time, the slider 11 acts on the opening and closing cover 13 through the connecting arm 12, so that the opening and closing cover 13 rotates open to expose the nozzle 2 inside the protective box 7 for spraying.

[0041] During the process, the mounting frame 18 is fixed at the required location by bolts. According to the required working width, the threaded rod 17 is rotated so that the threaded rod 17 acts on the T-tube 16 to slide on the outside of the threaded rod 17. When the appropriate length is adjusted, the threaded rod 17 is stopped from rotating. Then, according to the required angle, the screws of the fixing plate 15 are rotated to adjust the working angle of the protective structure 6. After the adjustment is completed, the screws are fixed to complete the adjustment and installation work.

[0042] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
