Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0025] like Figs. 1-2 As shown, a mobile dust removal device for coal mines is disclosed according to this utility model, comprising:

[0026] The vehicle body mechanism 1 includes a support base plate 11. Two baffles 12 are symmetrically connected to the left and right sides of the upper surface of the support base plate 11. Two fixed columns 13 are symmetrically arranged on the front side of the two baffles 12. A telescopic rod 21 is inserted into the inner cavity of the fixed column 13. A vertically arranged lifting cylinder 24 is connected to the front side of the fixed column 13.

[0027] The spraying mechanism includes a fixing block 22 connected to the top of the telescopic rod 21. The fixing block 22 is connected to the output end of the lifting cylinder 24. The fixing block 22 has a rotating shaft mounting hole. The rotating shaft mounting hole has several circularly distributed adjustment holes. A rotating shaft 25 is rotatably connected in the rotating shaft mounting hole. The two ends of the rotating shaft 25 are fixedly connected to fixing plates 23. The fixing plates 23 have several adjustment holes 2 that match the adjustment holes 1. Fixing screws pass through the adjustment holes 2 and the adjustment holes 1 to lock the rotating shaft 25. A spray frame 26 is installed on the rotating shaft 25. Several spray structures are installed on the spray frame 26.

[0028] Water receiving tank 3 is located below the spraying mechanism and is slidably connected to the supporting base plate 11;

[0029] The main water tank 5 is used for supplying water to the spray mechanism and recycling water, and the main water tank 5 is connected to the water receiving tank 3 through a water conveying assembly;

[0030] A dust removal mechanism 4 is located at the rear side of the spraying mechanism, and is fixedly connected with the upper end of the baffle 12.

[0031] Embodiments:

[0032] In the application, the fixed block 22 can be moved upward under the driving of the lifting cylinder 24 (positioned and guided by the telescopic rod 21 which slides and extends in the inner cavity of the fixed column 13), so that the spraying frame 26 mounted on the rotating shaft 25 is lifted, and the rotating shaft 25 can be rotated according to the spraying angle of the spraying structure. After the angle is adjusted, the rotating shaft 25 is locked by the fixed screw passing through the adjusting hole two and the adjusting hole one, that is, the angle and height of the spraying structure can be adjusted by the above-mentioned operation.

[0033] In the application, the water receiving tank 3 can slide on the supporting bottom plate under the action of the translation cylinder 8. When the dust removal device is not used or is turned over, the water receiving tank 3 can be retracted by the contraction of the output end of the translation cylinder 8, so as to reduce the overall volume. When the dust removal device performs the spraying operation, the water receiving tank 3 is pushed out by the extension of the output end of the translation cylinder 8, so that the water receiving tank 3 can receive part of the water mist falling down, and the water recovery is completed. An inclined downward filter screen 31 is arranged in the water receiving tank 3, which can make most of the dust in the falling water deposit on the lower side, and the water supply assembly is arranged on the higher side, so that the recovered water quality is better and is conducive to reuse. The water supply assembly includes a recovered water pipe 6 and a watering part 61. Multiple branch pipes can be arranged at the middle position of the watering part 61, and the lower surface of each branch pipe has multiple watering holes (spraying water on the ground after spraying can make the working environment better and further reduce the dust content). The recovered water pipe 6 can be connected in parallel on the side of the watering part 61. The filtered water in the water receiving tank 3 is pumped into the total water tank through the recovered water pipe 6 by the water pump 7 for spraying by the spraying mechanism. The electromagnetic valve is arranged on the recovered water pipe 6 and the watering part 61. The switching of watering and recovery can be completed by opening and closing the electromagnetic valve. The flow ratio can be adjusted by controlling the opening and closing degree. In order to make the movement of the water receiving tank 3 not affect the normal use of the water supply assembly, a section of the water supply assembly connected with the water receiving tank 3 can adopt a flexible pipe, and a corresponding avoiding space is arranged on the vehicle body mechanism 1.

[0034] In the application, the dust removal mechanism 4 first sucks the dust with water into the dust removal mechanism 4 by the suction of the air suction pump 43. After being filtered by the multiple filter layers 41, the air suction pump 43 sucks out the clean air and discharges it through the air outlet pipe 42, and the dust removal is completed.

[0035] The lower bottom surface of the support bottom plate 11 is further provided with at least one pair of support legs 14 driven by a hydraulic cylinder. After the dust removal device is moved to a designated position by the walking wheels and the push frame rod, the support legs 14 are driven to extend out and contact the ground by the hydraulic cylinder to support and position the dust removal device. When movement is needed, the support legs 14 are retracted by the hydraulic cylinder.

[0036] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
