Description

Technical Field

[0001] This utility model relates to the field of construction dust control technology, and in particular to a high-efficiency dust control device for highway construction dust. Background Technology

[0002] With the rapid advancement of highway construction in my country, dust pollution generated during construction is becoming increasingly serious, posing a severe threat to the construction site environment, surrounding air quality, and the health of construction workers. Traditional spray equipment has a fixed nozzle angle, which cannot be flexibly adjusted according to changes in the construction area, resulting in some areas not being sprayed and creating "dead zones." To address this issue, we have proposed a high-efficiency dust removal equipment for highway construction. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a high-efficiency dust removal device for highway construction.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-efficiency dust suppression device for highway construction includes an L-shaped fixing component. A protective box is fixed to the L-shaped fixing component, and a rotating device is installed inside the protective box. A fixing block is connected to the rotating device, and a fixing plate is fixed to the upper end of the fixing block. A rotating shaft is connected to one side of the fixing plate, and two rotating plates are installed on the rotating shaft. The two rotating plates are arranged crosswise. A Venturi nozzle is installed on the rotating plate, and a conveying structure is connected to one side of the Venturi nozzle. A hydraulic telescopic mechanism is installed at the upper end of the fixing block, and an extension mechanism is connected to the hydraulic telescopic mechanism. The extension mechanism is connected to the two rotating plates.

[0006] Preferably, the rotating device includes a servo motor fixed to one side of the protective box, a reducer installed inside the protective box, the output shaft of the servo motor connected to the reducer, a rotating block connected to the reducer, the rotating block penetrating the side wall of the protective box and extending to the upper end of the protective box, and the lower end of the fixed block fixed to the upper end of the rotating block.

[0007] Preferably, the conveying structure includes a first connecting pipe connecting two Venturi nozzles on the same side, a second connecting pipe connecting the two first connecting pipes, and a conveying pipe connected to one side of the second connecting pipe.

[0008] Preferably, the hydraulic telescopic mechanism includes a hydraulic cylinder fixed on a fixed block, a slider connected to the end of the output shaft of the hydraulic cylinder, a groove provided on one side of the fixed plate, and the slider being engaged in the groove.

[0009] Preferably, the extension mechanism is rotatably connected to two connecting rods on one side of the slider, and one side of one connecting rod on the same side is rotatably connected to one end of a rotating plate on the same side.

[0010] Preferably, the L-shaped fastener has four mounting holes on one side.

[0011] In this utility model, the initial state is:

[0012] 1. The L-shaped fastener is fixed to one side of the spray vehicle body through the mounting holes, with all rotating plates in the retracted state and the nozzles facing the fixed direction;

[0013] 2. Start the spraying system: The servo motor starts, driving the reducer to output power. The reducer drives the rotating block to rotate, and the fixed block rotates accordingly. The rotating plate rotates 270 degrees back and forth as a whole.

[0014] 3. Expanding the spraying range: The hydraulic cylinder is activated, pushing the slider to slide in the groove. The slider drives the connecting rod to move, and the connecting rod pushes the rotating plate to expand outward. The two rotating plates unfold into a V-shaped structure, increasing the coverage angle of the Venturi nozzle and forming a wide-angle spray.

[0015] 4. Water supply: The external water supply system delivers water to the second connecting pipe through the delivery pipe. The second connecting pipe distributes the water to the first connecting pipes on both sides, and finally delivers it to the Venturi nozzles. The Venturi nozzles use high-speed airflow to atomize and spray the water, achieving efficient dust suppression.

[0016] 5. End of spraying: The hydraulic cylinder moves in the reverse direction, the slider returns to its original position, the rotating plate retracts, the servo motor controls the rotating shaft to reset, and the nozzle returns to its initial state.

[0017] This utility model has the following advantages:

[0018] 1. The rotating shaft is controlled by a servo motor to achieve full coverage of the spraying range of the nozzle;

[0019] 2. The hydraulic telescopic mechanism drives the connecting rod to expand and retract the nozzle structure, and the spray range is adjustable, enabling long-distance, large-area, and high-density spraying, which significantly improves dust removal efficiency.

[0020] 3. The L-shaped fastener and mounting hole design facilitates quick installation on various spray truck bodies, making it widely applicable;

[0021] In summary, this utility model enables the nozzle structure to expand and retract, and the spraying range is adjustable, achieving long-distance, large-area, and high-density spraying, significantly improving dust removal efficiency. At the same time, it is easy to install quickly on various spraying vehicles, has wide applicability, improves the construction environment, and reduces occupational health risks.
