[0002] my country is a large coal-producing country with numerous large and small coal mines. Coal is a popular energy source in China, and the demand for it in the future will inevitably be huge, which will stimulate the rapid development of the coal mining industry. With the government's attention to the safety issues of coal mining, it will be possible to gradually achieve fully mechanized production in the future, which will inevitably further increase the demand for coal mine roadheaders. The cantilever roadheader integrates cutting, loading, walking, and operation functions, and is mainly used to cut underground rock, coal or semi-coal rock tunnels of any shape. At present, large and medium-sized roadheaders are constantly being innovated.

By setting the nozzle cover and the nozzle threadedly connected, it is easy to replace the nozzle cover with different numbers of spray holes to meet different dust reduction needs and improve the applicability of the equipment.

[0010] A further technical solution is that a protective plate is installed on the bottom surface of the shell, and the strength of the shell is improved by providing the protective plate to protect the shell and prevent stones from colliding with the equipment during the mining process.
