[0026] The inclination device 3 comprises a mounting frame 301, the bottom end of the mounting frame 301 is fixedly connected with the top end of a support frame 207, the bifurcated end of the support frame 207 is fixedly installed with a brake box 302, the inner wall of the brake box 302 is provided with a driving turntable 303, the outer side of the driving turntable 303 is fixedly installed with an eccentric rod 304, the outer side of the eccentric rod 304 is provided with a movable strip 305, the other end of the movable strip 305 is fixedly installed with a driving rack 307, the other side of the driving rack 307 is engaged with a driven gear 308, the movable end of the driven gear 308 extends to the outer side of the brake box 302 and is fixedly connected with the outer side of the fog cannon machine equipment 4.

[0027] By setting the deflection device 2 and the inclination device 3, the driving gear 203 contained in the deflection device 2 can drive the support frame 207 to drive the fog cannon machine equipment 4 to horizontally deflect through the follow-up gear ring 204, and the driving turntable 303 contained in the inclination device 3 can drive the movable strip 305 to drive the driving rack 307 to drive the driven gear 308 together with the fog cannon machine equipment 4 to vertically deflect through the eccentric rod 304, so that the fog cannon machine equipment 4 is adjusted and positioned under the driving of the above-mentioned devices, thereby facilitating the staff to adjust the dust-settling range of the fog cannon machine equipment 4, so as to facilitate the water spraying and dust-settling of the roadway with different radian, and improve the spraying range and applicability of the dust-settling device.

[0028] Specifically, the inside of the driving box 201 is provided with a closed circular groove 205, the inner wall of the closed circular groove 205 is slidably connected with a bottom rod 206, and the top end of the bottom rod 206 is fixedly connected with the bottom end of the follow-up gear ring 204.

[0029] In this embodiment, the bottom rod 206 can drive the follow-up gear ring 204 to slide along the inside of the closed circular groove 205.

[0030] Specifically, the driving gear 203 and the driving turntable 303 are both rotatably connected with the inner wall of the driving box 201 and the brake box 302 respectively through the built-in motor.

[0031] In this embodiment, the built-in motor can drive the driving gear 203 and the driving turntable 303 respectively.

[0033] In the embodiment, the eccentric rod 304 is located in the sliding groove inside the movable strip 305, so that the relative position between the eccentric rod 304 and the movable strip 305 changes during the movement of the eccentric rod 304, which causes the movement of the eccentric rod 304 to drive the vertical sliding of the movable strip 305, so that the movable strip 305 starts to displace along the surface of the sliding rod 306.

[0034] Specifically, the inner wall of the brake box 302 is fixedly installed with an electric push rod, and the movable end of the electric push rod is fixedly installed with a limiting rack 309, which is located below the driven gear 308.

[0035] In the embodiment, after the angle adjustment of the driven gear 308 is completed, the limiting rack 309 can be lifted by the electric push rod, so that the driven gear 308 gradually forms a meshing and locking state with the limiting rack 309, thereby avoiding the self-rotation of the driven gear 308.

[0036] In use, first, the staff moves the device to the specified position of the roadway by moving the base 1, and then starts the fog gun machine 4 and the water storage structure 5, so that the output pump outside the water storage bucket passes the water into the inside of the fog gun machine 4 through the connecting hose 6, so that the fog gun machine 4 sprays the water in the form of mist outward, thereby performing dust suppression treatment on the inside of the roadway.

[0037] When the angle of the fog gun machine 4 needs to be adjusted, the deflection device 2 and the inclination device 3 are started, so that the built-in motor in the drive box 201 can drive the drive gear 203 to rotate, so that the drive gear 203 can drive the driven gear ring 204 to mesh and transmit, so that the driven gear ring 204 can rotate in the closed circular groove 205 through the bottom rod 206, so that the driven gear ring 204 can drive the fog gun machine 4 to fan-shaped sweep through the support frame 207, so that the fog gun machine 4 is horizontally deflected.

[0038] The built-in motor in the brake box 302 can drive the drive turntable 303 to rotate, so that the drive turntable 303 drives the eccentric rod 304 to move in a circular motion. Since the eccentric rod 304 is located in the sliding groove inside the movable strip 305, the relative position between the eccentric rod 304 and the movable strip 305 changes during the movement of the eccentric rod 304, which causes the movement of the eccentric rod 304 to drive the vertical sliding of the movable strip 305, so that the movable strip 305 starts to displace along the surface of the sliding rod 306, so that the movable strip 305 drives the driven rack 307 to mesh and transmit the driven gear 308, so that the driven gear 308 starts to drive the fog gun machine 4 to be angularly deflected inside the mounting frame 301, so that the fog gun machine 4 is vertically deflected.
