AI Technical Summary
Existing excavators generate a lot of dust during construction. Traditional fog cannons have a fixed spray range and a delayed response, making it difficult to effectively control the spread of dust, which affects construction efficiency and environmental quality.
A sprinkler system is installed on the excavator, including an external water tank, water pump, sprinkler pipes and sprinkler tubes. The sprinkler system covers the work area and, in conjunction with a mist cannon, dynamically suppresses dust, achieving real-time suppression and control of dust.
It achieves dynamic and real-time dust suppression in the excavator operating area, significantly reducing dust generation and diffusion, improving the working environment, enhancing construction efficiency and management level, and meeting environmental protection policy requirements.
