Technical Field

[0001] This utility model relates to the technical field of dust control devices, specifically a dust control device for underground coal mine tunneling faces. Background Technology

[0002] During underground coal mine production, the tunneling of roadheaders and the cutting of coal by coal mining machines inevitably generate a large amount of dust, resulting in high dust concentrations in tunneling roadways and return airways of the working face. This seriously affects the health of underground workers. Effectively controlling dust at the tunneling face is of great practical significance for protecting the physical and mental health of underground workers. Therefore, dust control devices for underground tunneling faces in coal mines are urgently needed to solve the above problems. Utility Model Content

[0003] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a dust control device for underground tunneling faces in coal mines, so as to solve the problem mentioned in the background art that is of great practical significance for effectively controlling dust at tunneling faces and protecting the physical and mental health of underground workers.

[0004] This utility model provides the following technical solution: a dust control device for underground coal mine tunneling faces, comprising a water tank mechanism, the water tank mechanism including a water tank and a protective cover mechanism, the protective cover mechanism including a protective cover, a protective cover fixedly connected to the water tank, a tank cover fixedly connected to the water tank, a water pump fixedly connected inside the protective cover, a water pipe fixedly connected to the water pump, a spray head and a fan fixedly connected to the tank cover, the water pipe and the spray head connected, a water dispenser fixedly connected to the water tank, a rotating seat fixedly connected inside the protective cover, an adjusting plate rotatably connected to the rotating seat, and the adjusting plate having eighteen spring grooves. An internally fixed spring is connected, and a locking bead is fixedly connected to the spring. The rotating seat has eighteen locking slots. Water is added to the water tank through a water adder, and a water pump draws the water out and delivers it to the spray head through a water pipe for spraying. Dust in the coal mine settles when it encounters the water mist, achieving the purpose of dust prevention. The fan is activated to blow the water mist, making the coverage area of ​​the water mist wider and the dust prevention effect better. The spray angle of the water mist is adjusted by rotating the adjustment plate, thereby adjusting the spray height of the water mist and improving the dust prevention effect. The locking bead engages with the locking slot to fix the adjustment plate of the adjustment angle. This method has a simple structure, is easy to use, and improves the working efficiency and practicality of the device.

[0005] Furthermore, wheels are fixedly connected to the bottom of the water tank. Pushing the water tank causes the wheels to rotate, thus moving the device and making it easy to change the dustproof position, which is convenient to use.

[0006] Furthermore, a level gauge is fixedly connected to the water tank, allowing for observation of the remaining water level and facilitating timely replenishment, thus improving the practicality of the device.

[0007] Furthermore, the protective cover is made of transparent material, allowing easy observation of the working status of the spray head and fan, facilitating maintenance by staff.

[0008] Furthermore, the protective cover is provided with a dustproof net groove, in which a dustproof net is movably placed. The dustproof net filters the dust drawn in by the fan, preventing dust from contaminating the inside of the protective cover and damaging the spray head and fan. The dustproof net is regularly removed for cleaning or replacement to prevent it from becoming clogged, reducing ventilation and affecting the dustproof effect, thus improving the practicality and operational stability of the device.

[0009] Furthermore, the protective cover has a maintenance cover slot, in which a maintenance cover is movably placed. Removing the maintenance cover facilitates maintenance of the spray head and fan, improving the practicality and ease of operation of the device.
