When in use, if multi-angle and large-scale dust reduction is required, it is necessary to rely on workers to move and adjust, and when spraying dust reduction mist, the dust adsorption of the droplets sprayed in a single direction at the initial start of the device will be in a saturated state, resulting in low dust reduction efficiency.

[0039] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0040] Reference Figure 1-10As shown, an environmentally friendly dust reduction device for construction engineering described in the present invention includes a mobile vehicle 1, a wind angle adjustment component 2, a high-speed spray nozzle 3, a high-speed airflow cylinder 4, a horizontal adjustment support frame 5 and a wavy transmission component 6, the horizontal adjustment support frame 5 is rotatably connected to the mobile vehicle 1, the wind angle adjustment component 2 is rotatably connected to the horizontal adjustment support frame 5, the wind angle adjustment component 2 is rotatably connected to the high-speed airflow cylinder 4, the wavy transmission component 6 is rotatably connected to the horizontal adjustment support frame 5, the wavy transmission component 6 is fixedly connected to the wind angle adjustment component 2, the wavy transmission component 6 can drive the high-speed airflow cylinder 4 to rotate, the horizontal adjustment support frame 5 is rotatably connected to the mobile vehicle 1, and the wavy transmission component 6 is arranged on the mobile vehicle 1.

[0041] When in use, the device is moved to the edge of the building construction by the mobile vehicle 1, and the high-speed spray port 3 is directed toward the edge side where dust is generated. Then, by starting the device, high-speed spray is generated through the high-speed spray port 3, and the high-speed spray is transmitted far away through the high-speed airflow cylinder 4. During operation, power is generated through the wavy transmission component 6, so that the horizontal adjustment support frame 5 is deflected. When rotating, the wind angle adjustment component 2 is also rotated through the wavy transmission component 6 to adjust the direction of the high-speed spray port 3. In the process of being too high, the wavy transmission component 6 will push the high-speed airflow cylinder 4 to rotate, thereby adjusting the internal airflow outflow direction of the wind angle adjustment component 2, and then changing the spraying range and length of the high-speed spray during the lifting process, so as to achieve a large range (the rotation angle range of the horizontal adjustment support frame 5) of dust reduction at a fixed position, and in the process of range dust reduction, it can also produce The effect of swinging the high-speed spray nozzle 3 up and down, and the effect will change with the high-speed spray delivery distance and spraying effect produced by different directions. When the direction changes from low to high, the wind angle adjustment component 2 and the high-speed airflow cylinder 4 rotate relative to each other, and the airflow ejected in the wind angle adjustment component 2 will also produce the effect of gradually moving toward the axis of the high-speed spray nozzle 3, thereby gradually increasing the spray distance and reducing the spray range. It is possible to carry out dust reduction at some low places and then at high places where dust is generated during construction. It is possible to reduce the dust content at low places first, and then spray from high places. The dust adsorbed by the mist is always in an unsaturated state, and is always in a highly efficient state of droplets adsorbing dust, thereby increasing the dust reduction efficiency, saving water resources, energy saving and environmental protection, and preventing the initial dust reduction efficiency caused by single high-altitude spraying due to the saturation of dust adsorbed by the droplets, which requires high power and large consumption of spray.
