The right side of the mounting tube 5 is connected with an open circular plate 11 A fan 12 is installed on the open circular plate 11, and a filter screen 13 for filtering dust is connected to the area on the right side of the open circular plate 11 in the installation cylinder 5 and the opening of the open circular plate 11. An annular nozzle 10 for spraying water to the filter screen 13 is connected in the installation cylinder 5. The annular nozzle 10 is located on the left side of the open circular plate 11 and on the outside of the fan 12. An infusion assembly for inputting water into the annular atomizing nozzle 8 and the annular nozzle 10 is provided on the water tank 2. The infusion assembly includes a pressure pump 22 installed on the left side of the top of the water tank 2. The pressure pump 22 is connected to the water tank 2 and the annular atomizing nozzle 8 through a hose 23. A pressure pump 24 is installed on the right side of the top of the water tank 2. The pressure pump 24 is connected to the water tank 2 and the annular nozzle 10 through a hose 25.

[0027] Push the push rod 26 to move the device to a suitable position. During the movement of the device, when it passes through complex terrain (such as potholes and slopes) on the construction site, shock absorption is achieved through the synergistic effect of the hydraulic damper 151 and the spring 152. Specifically, the spring 152 is mainly used to absorb the impact force of the ground and store this energy through elastic deformation, thereby buffering the instantaneous impact and reducing the impact on the device and the operator; the hydraulic damper 151 is used to dissipate vibration energy, convert mechanical energy into heat energy, and quickly attenuate the vibration amplitude and duration, which not only prevents the occurrence of resonance, but also improves the stability and controllability of the device on complex terrain. The hydraulic damper 151 is a prior art and will not be repeated here. And when the device is performing water spraying and dust reduction operations, the hydraulic damper 151 and the spring 152 can also provide good shock absorption and vibration resistance performance to ensure the stability of the device. By connecting the water injection pipe 21 to an external water source, water can be injected into the water tank 2. By controlling the pressure pump 22 to work, the water in the water tank 2 can be input into the annular atomizing nozzle 8 through the hose 23. The annular atomizing nozzle 8 then atomizes and sprays the water. By controlling the fan 12 to work, the water mist can be blown out, thereby increasing the diffusion speed of the water mist, expanding the coverage area of ​​the water mist, and improving the dust reduction efficiency and effect.

[0028] The wind speed sensor 92 can detect the wind speed in the installation tube 5, and the dust sensor 91 can detect the dust amount in the airflow in the installation tube 5. The wind speed sensor 92 and the dust sensor 91 are prior art and will not be described in detail here. When the wind speed sensor 92 detects that the wind speed in the installation tube 5 is less than the preset value, it means that there is a lot of dust adhering to the filter 13. The wind speed sensor 92 sends a signal to the controller (the controller is not shown in the figure, the controller is prior art and will not be described in detail here). The controller controls the pressure pump 2 24 to work, and the water in the water tank 2 is input into the annular nozzle 10 through the hose 2 25. The annular nozzle 10 then sprays the water to the filter 13 to clean the filter 13. When the wind speed sensor 92 detects that the wind speed in the installation tube 5 is greater than the preset value, the wind speed sensor 92 sends a signal to the controller, and the controller controls the pressure pump 2 24 to turn off. When the dust sensor 91 detects that the dust amount in the airflow in the installation cylinder 5 is greater than the preset value, it also means that there is a lot of dust adhering to the filter 13. The dust sensor 91 sends a signal to the controller, and the controller controls the pressure pump 24 to work and spray water to clean the filter 13. When the dust sensor 91 detects that the dust amount in the airflow in the installation cylinder 5 is less than the preset value, the dust sensor 91 sends a signal to the controller, and the controller controls the pressure pump 24 to turn off. In this way, the device can automatically clean the filter 13 without frequent manual disassembly and cleaning, which can save time and effort, reduce labor costs, improve the practicality and work efficiency of the device, help reduce maintenance workload, and ensure the long-term stability and efficiency of dust treatment effects.

[0029] Push the kick plate 18 with your foot to rotate in the direction close to the mounting frame 1, so that the rotating rod 16 can drive the insertion block 17 to rotate downward and insert into the ground, so as to push the rotating rod 16 upward, thereby pulling the connecting sleeve 153 and the wheel 19 upward to separate from the ground, and then the device can be fixed to prevent the device from moving automatically during the water spraying and dust reduction operation, so as to improve stability and safety. When it is necessary to release the device, push the kick plate 18 with your foot to rotate in the direction away from the mounting frame 1, so that the rotating rod 16 can drive the insertion block 17 to rotate upward and pull it out of the ground, release the fixation of the device, and the wheel 19 then moves downward to contact the ground.

[0030] The above-mentioned embodiments only express the preferred implementation of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications, improvements and substitutions can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
