Description

Technical Field

[0001] The utility model relates to a dust reduction type tunneling machine for underground mining, belonging to the technical field of dust reduction devices for tunneling machines. Background Art

[0002] A roadheader is a machine used to dig straight underground tunnels. Roadheaders are divided into open-type roadheaders and shield-type roadheaders, which are mainly composed of a traveling mechanism, a working mechanism, a loading mechanism, and a transfer mechanism. As the traveling mechanism moves forward, the cutting head in the working mechanism continuously breaks up the rock and transports the broken rock away. The roadheader will generate a lot of dust during use, so a dust suppression device is required.

[0003] According to the announcement number CN211081845U, a dust suppression spray for a tunnel boring machine is disclosed, including a support frame, a placing frame is fixedly connected to one side of the support frame, a fixing plate is fixedly connected to one side of the placing frame, fixing bolts are provided on the outer surface of the fixing plate, a side plate is fixedly connected to the outer surface of the support frame, a water storage tank is provided on the upper surface of the placing frame, a protection box is provided on the upper surface of the support frame, a water pump is provided inside the water storage tank, and a water pipe is fixedly connected to one side of the water pump. The dust reduction spray for the tunnel boring machine is provided with a fixing plate, a side plate and a mounting plate. The staff first fixes the support frame at the installation position through the side plate and fixing bolts, and then fixes the fixing plate on one side thereof, and finally fixes the mounting plate below it. After completion, the water storage tank and the protection box are respectively placed on the top of the support frame and the placement frame to carry out dust reduction work, thereby achieving the purpose of convenient installation and use. When the above device is in use, since the water storage tank is not fixed, the stability of the water storage tank is poor. At the same time, when the device is not in use, the atomizing nozzle is still exposed to the outside, which makes the atomizing nozzle easy to be damaged. Utility Model Content
