The fog cannon machine 211 can pressurize the water source provided by the water supply assembly 23 to form water mist and spray it towards the tunnel face 100. The angle adjusting unit 212 is arranged below the fog cannon machine 211. The angle adjusting unit 212 is used to adjust the horizontal angle and the pitch angle of the barrel.

[0032] Please refer to Figure 3 The pressurizing device in the fog cannon machine 211 pressurizes the water source provided by the water supply assembly 23 to form fine water mist particles at the barrel. The barrel is directed towards the rear side of the vehicle body 10 to ensure that the water mist can be directly sprayed to the tunnel face 100 to cover the dust source area, thereby achieving high-efficiency dust removal effect. The water mist particles formed by the fog cannon machine 211 can effectively adsorb and settle the dust in the air, achieving high-efficiency dust removal of the tunnel face 100, improving the tunnel construction environment, and ensuring the health and safety of the construction personnel. As the position and shape of the tunnel face 100 may change during the construction process, the operator can quickly adjust the spraying angle of the barrel through the angle adjusting unit 212 to ensure that the water mist can always act on the dust source accurately, so that the spraying assembly 21 has good flexibility and adaptability. It should be noted that the fog cannon machine 211 can be a fog cannon machine 211 in the prior art.

[0033] In an embodiment, the angle adjusting unit 212 comprises a turntable, a reduction motor, and a hydraulic push rod. The turntable is rotatably arranged at the tail of the bearing platform 12. The fog cannon machine 211 is installed on the turntable. The reduction motor is used to drive the turntable to rotate horizontally to adjust the horizontal angle of the barrel. The hydraulic push rod is telescopically connected between the turntable and the barrel. The hydraulic push rod can be extended and retracted to drive the barrel to vertically swing to adjust the pitch angle of the barrel.

[0034] Further, the fog cannon machine 211 is installed on the turntable. The turntable is provided with a vertically extending rotating shaft. The reduction motor drives the turntable to rotate around the rotating shaft to rotate the turntable in the horizontal direction, thereby adjusting the horizontal angle of the fog cannon machine 211. The hydraulic push rod is arranged between the turntable and the barrel of the fog cannon machine 211. The extension and retraction of the hydraulic push rod makes the barrel of the fog cannon machine 211 vertically swing, thereby adjusting the pitch angle of the fog cannon machine 211. Through the cooperation of the turntable and the hydraulic push rod, the direction of the barrel of the fog cannon machine 211 can be adjusted, thereby adjusting the spraying direction of the fog cannon machine 211. The spraying assembly 21 can flexibly adapt to the position change of the tunnel face 100 under different construction conditions, thereby improving the coverage range of the water mist and the dust removal effect.

[0035] In an embodiment, the fog curtain assembly 22 comprises a water ring 221, a high-pressure water pump and a plurality of spray heads 222. The water ring 221 is in a semi-ring shape, and the plurality of spray heads 222 are spaced apart and installed on the water ring 221. Each spray head 222 is arranged along the radial direction of the water ring 221 and faces outwardly.

The water ring 221 is connected to the water tank 231, and the water supply pipe is connected between the water tank 231 and the spray assembly 21.

[0038] It can be understood that, when the water tank 231 is in a semi-elliptical cylindrical shape, it matches the shape of the tunnel. During the driving of the tunnel water mist dust removal vehicle in the tunnel, the water tank 231 avoids colliding with the inner wall of the tunnel, optimizes the space utilization of the tunnel water mist dust removal vehicle as much as possible while ensuring the water storage capacity. When the water tank 231 is in a rectangular shape, it is convenient to manufacture and stable to install. The shape of the water ring 221 matches the water tank 231, so that the water ring 221 can be connected to the edge of the water tank 231.

The tail of the second shell 32 can be opened to form a spray channel, and the tail of the second shell 32 is in a tapered slope shape when closed, which is arched upward toward the rear of the vehicle body 10.

[0040] Please refer to Figure 4 and Figure 5, the top of the first shell 31 is arched upward like a roof, and the tail of the second shell 32 is arched backward like a slope when closed, which can effectively improve the structural strength of the shield shell 30 to withstand the impact force of falling rocks in the tunnel, thereby providing effective protection for the dust removal system 20. In addition, the top of the first shell 31 is arched upward, so that the falling rocks falling onto the top of the first shell 31 can slide to both sides of the shield shell 30 under the action of gravity, thereby avoiding the extrusion of the shield shell 30 caused by the accumulation of falling rocks. The second shell 32 includes a first sub-shell and a second sub-shell that can be combined with each other, the first sub-shell and the second sub-shell are respectively rotatably connected to opposite sides of the first shell 31, and the connection between the first sub-shell and the second sub-shell and the first shell 31 forms two connection shafts, respectively. The first sub-shell and the second sub-shell can rotate around the connection shafts connected thereto, thereby realizing flexible opening and closing of the second shell 32 to facilitate smooth spraying of the spray assembly 21.

[0042] Further, the linkage assembly is connected between the electric push rod and the first sub-shell and the second sub-shell, which can realize synchronous opening and closing of the first sub-shell and the second sub-shell. When the push rod of the electric push rod is extended, the linkage assembly converts the linear motion of the push rod into the rotation of the first sub-shell and the second sub-shell, so that the tail of the second shell 32 is opened outward to form a spray channel; when the push rod of the electric push rod is retracted, the linkage assembly drives the tail of the second shell 32 to close backward to restore the slope structure, ensuring the accuracy and stability of the opening and closing action of the second shell 32, and flexibly adjusting the state of the shield shell 30 under different working conditions to meet the needs of spraying operation and driving protection.

[0043] In an embodiment, the tunnel water mist dust removal vehicle further comprises an electric control system 50, the electric control system 50 is communicatively connected to the spray assembly 21, the mist curtain assembly 22 and the electric push rod.

[0044] It should be noted that the operator directly controls the start, stop, spray intensity adjustment and spray direction adjustment of the spray assembly 21 and the mist curtain assembly 22 through the electric control system 50, and can control the action of the electric push rod to realize the opening and closing of the tail of the shield shell 30.
