Description

TECHNICAL FIELD

[0001] The application relates to a dust falling mechanism of a coal mine tunneling machine. BACKGROUND

[0002] The tunneling machine plays a key role in coal mine production and is an important technical measure to ensure high and stable production of the mine. Through efficient crushing and transportation operation, the tunneling machine can significantly improve the production efficiency of the coal mine, reduce the labor intensity, and ensure the safety and production efficiency of the mine. A large amount of dust is generated in the operation process of the tunneling machine, and the dust falling mechanism is needed to spray water mist on the dust. The water mist and the dust combine to make it settle down, thereby reducing the content of dust in the air.

[0003] When the tunneling machine is used, the dust falling mechanism is fixed on the tunneling machine to fall dust on the tunneling position. However, the position of the spray head on the dust falling mechanism is fixed and can only change with the change of the tunneling position of the tunneling machine. When the amount of dust is large, it is not convenient to adjust the water mist spraying range. In addition, when the dust falling mechanism is not used, the atomizing spray head is exposed outside. Since there is a lot of dust in the coal mine, the atomizing spray head is easily blocked, thereby affecting the use of the dust falling mechanism.

[0004] Therefore, it is desirable to provide a dust falling mechanism of a coal mine tunneling machine. CONTENT OF THE INVENTION
