[0029] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0032] Example 1:

[0033] Please see Figures 1-3 This is the first embodiment of the present invention.

[0034] This embodiment provides a dust suppression device for inclined coal seam mining, including:

[0035] The bracket 1 has a support mechanism 101 on its inner side, an adjustment mechanism 102 on its top side, a dust suppression mechanism 103 at one end of the support mechanism 101, and a fixing mechanism 104 on its bottom side.

[0036] The support mechanism 101 includes a platform 2 fixed to the top of the inner side of the bracket 1. A servo motor 3 is fixed at the center of the top side of the platform 2. A lead screw 4 is fixed through the output end of the servo motor 3 and passes through the platform 2. Slide rods 5 are slidably inserted at the four corners of the top side of the bracket 1. A top plate 6 is fixed at the top of the slide rod 5. A support plate 11 is installed on the top side of the top plate 6. A rectangular plate 7 is fixed at the bottom of the slide rod 5. A threaded cylinder 8 is fixed at the center of the top side of the rectangular plate 7. The threaded cylinder 8 is rotatably connected to the lead screw 4.

[0037] Specifically, the adjustment mechanism 102 includes a rectangular groove 13 at the center of the top plate 6. A mounting seat 9 is fixed on the top side of the top plate 6. A support plate 11 is rotatably mounted on the mounting seat 9 through a connecting seat 10. An anti-slip rib 12 is fixed on the top side of the support plate 11. A rack 14 is slidably mounted inside the rectangular groove 13. A gear 19 is fixed on the circumferential surface of the connecting seat 10. The gear 19 meshes with the rack 14. A limit rod 15 is fixed at one end of the rack 14 and slides through the inside of the rectangular groove 13. A threaded rod 17 is rotatably inserted at one end of the inside of the rectangular groove 13. One end of the threaded rod 17 is rotatably connected to the rack 14 through a rotating seat 16. The other end of the threaded rod 17 passes through the top plate 6 and is fixed to a turntable 18.

[0038] Furthermore, by cooperating with the gear 19 and the rack 14, the tilt angle of the support plate 11 can be adjusted so that it is parallel to the support surface, thereby providing good support while reducing dust and improving safety during coal mining.

[0039] In use, the servo motor 3 is controlled to drive the output screw 4 to rotate, which, in conjunction with the threaded cylinder 8, drives the rectangular plate 7 to move up and down. This changes the height of the top plate 6 and its top support plate 11 via the slide rod 5. At the same time, the turntable 18 is rotated, causing the threaded rod 17 to rotate, which in turn pushes the rack 14 to slide inside the rectangular groove 13. At this time, the rack 14 drives the gear 19 to rotate, changing the tilt angle of the support plate 11 so that it is parallel to the support surface. Thus, when the dust suppression equipment is used, it can play a supporting role inside the mine, preventing collapse during coal mining and improving the safety of coal mining.

[0040] In summary, by using the structure of the support mechanism 101, the dust suppression equipment can be placed inside the mine and positioned where support is needed. This provides support without affecting the dust suppression operation, thereby improving safety during coal mining.

[0041] Example 2:

[0042] Please see Figures 4-5 This is the second embodiment of the present utility model.

[0043] Specifically, the dust suppression mechanism 103 includes a fixed base 20 fixed to one end of the top plate 6. A water spray pipe 21 is rotatably installed inside the fixed base 20. Atomizing nozzles 22 are evenly fixed on the circumference of the water spray pipe 21. One end of the water spray pipe 21 passes through the fixed base 20 and is fixed to a disc 23. Positioning holes 24 are evenly opened on the side of the disc 23. A sliding groove 25 is opened on one end of the inner side of the top plate 6. A locking block 26 is slidably installed inside the sliding groove 25. A spring 27 is fixedly connected between the locking block 26 and one end of the inner side of the sliding groove 25. The locking block 26 is snapped into the inside of the positioning hole 24. A support platform 28 is fixed to one corner of the top side of the top plate 6. A water pump 29 is fixed to the top side of the support platform 28. The output end of the water pump 29 is connected to one end of the inner side of the water spray pipe 21. A water storage tank 30 is fixed to one end of the bottom side of the bracket 1. The input end of the water pump 29 is connected to the inside of the water storage tank 30.

[0044] Furthermore, through the structure of the disc 23 and the locking block 26, the atomizing nozzle 22 can be adjusted to the required tilt angle, thereby better removing dust from the air and improving the environment of coal mining.

[0045] Specifically, the fixing mechanism 104 includes limiting seats 32 symmetrically fixed at both ends of the bottom side of the bracket 1, a rotating platform 33 rotatably installed inside the limiting seat 32, a roller 34 symmetrically rotatably installed at one end of the rotating platform 33, a through hole 35 opened on the side of the rotating platform 33, and fixing rods 36 symmetrically slidably inserted at both ends of the bottom side of the bracket 1, the fixing rods 36 slidably inserted inside the through hole 35.

[0046] Furthermore, by cooperating with the fixing rod 36 and the through hole 35, the position of the roller 34 can be changed as needed to prevent the dust suppression equipment from shifting during use, making it more convenient for operators to use.

[0047] In use, after the dust suppression equipment is moved to the required position, the fixing rod 36 is pulled out, and the rotating table 33 is rotated to move the rollers 34 to both sides of the bracket 1, thereby shifting the force position of the bracket 1. At this time, the disc 23 can be rotated to drive the water spray pipe 21 to rotate, and the atomizing nozzle 22 is adjusted to the required tilt angle. At this time, the locking block 26, with the cooperation of the spring 27, is fastened to the inside of the positioning hole 24 to fix the position of the disc 23. Then, the water pump 29 is controlled to deliver clean water from the inside of the water storage tank 30 to the inside of the water spray pipe 21. The water is then atomized and sprayed out through the atomizing nozzle 22 to adsorb tiny particles in the air, thereby removing dust and improving the mining environment in coal mines.

[0048] In summary, by using the dust suppression mechanism 103 and the fixing mechanism 104, and by using the fixing rod 36 and the through hole 35, the roller 34 can be moved to both sides of the bracket 1 during dust suppression, and the roller 34 can be re-fixed to the bottom of the bracket 1 when it needs to be moved, making the dust suppression equipment more flexible and convenient to use.
