The two groups of electric fan bodies 6 are respectively installed on the top of the two groups of rotating shafts 5 by screws 17. Because the two groups of rotating shafts 5 are respectively fixedly connected to the two groups of gears 45, when the two groups of racks 44 drive the two groups of gears 45 to rotate, they will also drive the two groups of rotating shafts 5 to rotate, thereby driving the two groups of electric fan bodies 6 respectively connected to the two groups of rotating shafts 5 by screws 17 to rotate and swing.

[0032] Example 2

[0033] On the basis of Example 1, a preferred embodiment of the cooling and dust removal device for a coal mining working face provided by the present invention is as follows: Figures 1 to 5 As shown: the transmission mechanism 4 includes a servo motor 41, a threaded rod 42, a slider 43, a rack 44, a gear 45 and a limit rod 46. The servo motor 41 is provided on the back of the dust removal equipment body 2. The output end of the servo motor 41 is fixedly connected to the threaded rod 42. The surface of the threaded rod 42 is threadedly connected to the slider 43. The side of the slider 43 is fixedly connected to the rack 44. The side of the rack 44 is meshed with the gear 45. The bottom of the gear 45 is fixedly connected to the limit rod 46.

[0034] In this embodiment, two groups of racks 44 and gears 45 are respectively provided. A transverse groove matching the slider 43 is opened on the top of the dust removal equipment body 2, and the slider 43 is embedded in the transverse groove on the top of the dust removal equipment body 2. Because the slider 43 is engaged with the threaded rod 42, when the threaded rod 42 rotates, it will drive the slider 43 to slide back and forth inside the transverse groove on the top of the dust removal equipment body 2. At this time, the two groups of racks 44 fixedly connected to the slider 43 will move back and forth accordingly. Because the two groups of gears 45 are respectively engaged with the two groups of racks 44, when the two groups of racks 44 move, they will drive the two groups of gears 45 to rotate together.

[0035] In this embodiment, two groups of limiting rods 46 are fixedly connected to the bottom of each group of gears 45, and the tops of the dust removal equipment body 2 and the cooling equipment body 3 are provided with annular sliding grooves. The four groups of limiting rods 46 are respectively embedded in the annular grooves on the tops of the dust removal equipment body 2 and the cooling equipment body 3. Because the four groups of limiting rods 46 are respectively fixedly connected to the two groups of gears 45, when the gear 45 rotates, it will drive the four groups of limiting rods 46 to slide in the annular grooves on the tops of the dust removal equipment body 2 and the cooling equipment body 3, and have a certain limiting effect on the two groups of gears 45.

[0036] The working principle and use process of the utility model are as follows: First, the two sets of electric fan bodies 6 are respectively installed on the top of the two sets of rotating shafts 5 by screws 17, and then the two sets of first nozzles 8 and the two sets of second nozzles 10 are respectively placed on the top of the two sets of first connecting tubes 7 and the second connecting tubes 9, so that the mounting holes of the first nozzles 8 and the second nozzles 10 correspond to the mounting holes of the first connecting tubes 7 and the second connecting tubes 9. Then, multiple sets of fixing bolts 16 are respectively passed through the mounting holes of the two sets of first nozzles 8, the first connecting tubes 7, the second nozzles 10 and the second connecting tubes 9, and the fixing bolts 16 are tightened to fix the first nozzles 8 and the second nozzles 10 to the first connecting tubes 7 and 9. The second connecting pipe 9 is connected. After the connection is completed, the entire device can be pushed to connect through the four sets of universal wheel bodies 15. When the location to be placed is uneven, the staff can slide the protective plates 12 to both sides to expose the controller body 11, and then activate the electric telescopic rod 13 at the recessed corner through the controller body 11, so that the electric telescopic rod 13 drives the universal wheel body 15 to descend through the adjustment plate 14. When the universal wheel body 15 descends to contact with the ground and the entire device is in a horizontal state, the operation can be stopped. At this time, the universal wheel body 15 will stay in the current position, thereby achieving the purpose of improving the overall stability of the device and preventing the entire device from tilting.

[0037] After the adjustment is completed, the dust removal device body 2 and the cooling device body 3 are started through the controller body 11, so that the dust removal device body 2 sprays water through the first nozzle 8 to remove dust and the cooling device body 3 sprays cold mist through the second nozzle 10 to cool down. Then, the servo motor 41 is started to drive the threaded rod 42 to rotate. Because the slider 43 is engaged with the threaded rod 42, when the threaded rod 42 rotates, it will drive the slider 43 to slide back and forth inside the horizontal groove at the top of the dust removal device body 2. At this time, the two sets of racks 44 fixedly connected to the slider 43 will move back and forth accordingly. Because the two sets of gears 45 are respectively engaged with the two sets of racks 44, when the two sets of racks 44 move, they will drive the two sets The gears 45 rotate together. At this time, the two groups of rotating shafts 5 fixedly connected to the two groups of gears 45 will rotate accordingly, thereby driving the two groups of electric fan bodies 6 connected to the two groups of rotating shafts 5 by screws 17 to rotate and swing. Because the four groups of limiting rods 46 are fixedly connected to the two groups of gears 45, respectively, when the gears 45 rotate, it will drive the four groups of limiting rods 46 to slide in the annular grooves at the top of the dust removal equipment body 2 and the cooling equipment body 3, respectively, and have a certain limiting effect on the two groups of gears 45. When the electric fan body 6 swings, it will blow away and diffuse the water sprayed by the first nozzle 8 and the cold mist sprayed by the second nozzle 10, thereby achieving the purpose of expanding the dust removal range and the cooling range.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
