DETAILED DESCRIPTION

[0024] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] like Figures 1-8As shown, the spray dust suppression device for a mining excavator provided in this embodiment includes a body 1, an engine 2 is installed on the body 1, a mobile crawler 3 is installed at the bottom of the body 1, a driving cabin 4 is installed on the body 1, a mechanical arm 5 is installed on the body 1, a first gear 6 is installed on the body 1, two fixing frames 7 are symmetrically installed on the first gear 6, a wind tube 8 is installed between the fixing frames 7, a grille plate 9 is installed on one side of the wind tube 8, a first drive motor 10 is installed on one side of the grille plate 9, a fan 11 is installed in the wind tube 8, the output end of the first drive motor 10 is connected to the fan 11, a water injection ring 12 is installed on the side of the wind tube 8 away from the grille plate 9, and a plurality of atomizing nozzles 13 are equidistantly installed on the water injection ring 12, a first vertical plate 14 is installed on the engine 2, a water tank 15 is installed on the first vertical plate 14, and a second vertical plate 16 is installed on the engine 2. A water pump 17 is installed on the top of the second vertical plate 16, and a water inlet pipe 18 is installed on one side of the water pump 17. A water outlet hose 19 is installed on the side of the water pump 17 away from the water inlet pipe 18. The water outlet hose 19 is connected to the water injection ring 12. A disc 20 is rotatably installed on the inner wall of the first gear 6, and a rack 21 is slidably installed on the body 1. A support plate 22 is installed on the body 1, and a second drive motor 23 is installed on one side of the support plate 22. A second gear 24 is installed on the second drive motor 23. The rack 21 is meshed with the first gear 6 and the second gear 24. The second drive motor 23 drives the second gear 24 to rotate forward and backward to drive the rack 21 to reciprocate. As the rack 21 reciprocates to drive the first gear 6 to rotate forward and backward, the wind tube 8 can be continuously rotated toward the robotic arm 5, thereby increasing the dust reduction range of the atomizing nozzle 13.

[0026] Further, such as Figures 1-8 As shown, an electric telescopic rod 25 is installed on the first gear 6, one end of the electric telescopic rod 25 is connected to the wind tube 8, a circular plate 26 is installed on one side of the fixed frame 7, and a rotating rod 27 is rotatably installed on one side of the circular plate 26, one end of the rotating rod 27 is connected to the wind tube 8, and the wind tube 8 can be adjusted up and down by pushing the electric telescopic rod 25, which is more convenient for dust reduction operations. A protective shell 28 is installed on the outer wall of the second drive motor 23 to protect the second drive motor 23 from interference from the external environment and thus reduce work efficiency. A sunscreen glass 36 is installed on the driving cabin 4 to reduce the driver's exposure to sunlight and thus affect normal operations.

[0027] Further, such as Figures 1-8As shown, a disassembly mechanism 29 is installed on one side of the grille plate 9, and the disassembly mechanism 29 includes a fixed frame 30 symmetrically installed thereon, two springs symmetrically installed on the inner wall of the fixed frame 30, and a clamping block 32 is installed on one side of the spring 31. Clamping grooves 33 are provided on both sides of the grille plate 9, and a pull rod 34 is installed on the outer wall of the clamping block 32. A fixing groove 35 adapted to the pull rod 34 is provided on the outer wall of the fixed frame 30, and the clamping groove 33 is adapted to the clamping block 32. By moving the pull rod 34, the clamping block 32 can be disengaged from the clamping groove 33 and retracted into the fixed frame 30. At the same time, the grille plate 9 loses its clamping fixation and can be conveniently replaced.

[0028] like Figures 1-8 As shown, the principle of the spray dust reduction device for a mining excavator provided in this embodiment is as follows: through the cooperation of the water pump 17, the water outlet hose 19, the water injection ring 12 and the atomizing nozzle 13, dust reduction can be sprayed toward the direction of the mechanical arm 5, and at the same time, the second drive motor 23 is used to drive the second gear 24 to rotate forward and reverse to drive the rack 21 to move back and forth. As the rack 21 moves back and forth to drive the first gear 6 to rotate forward and reverse, the wind tube 8 can be continuously rotated toward the mechanical arm 5, thereby increasing the dust reduction range of the atomizing nozzle 13 and effectively reducing the concentration of suspended particulate matter, inhalable particulate matter and fine particulate matter in the air.

[0029] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term and should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0030] It should be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other identical elements in the product or system comprising the element.

[0031] The above description shows and describes several preferred embodiments of the present invention. However, as previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge in the relevant field. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
