Description

Technical Field

[0001] The utility model relates to the technical field of mining construction, in particular to a tunneling device. Background Art

[0002] Mining, a comprehensive energy term, is the technology and science of mining mineral resources from the earth's crust and surface. In a broad sense, mining also includes the mining of coal and oil. The mining industry is an important raw material industry. Metallic ores are the main raw materials for the smelting industry, and non-metallic ores are important chemical raw materials and building materials.

[0003] Announcement No. (CN211058798U) discloses a tunneling device for mining construction. During the tunneling process, the exhaust fan is started to extract the air in the dust suction pipe, so that the dust suction pipe is in a negative pressure state, so that the dust-containing air in front of the tunneling device is sucked into the dust suction pipe. When the dust-containing air passes through the ventilation holes on the plug plate, the dust in the air is filtered by the filter, so that the clean air flows out from the other end of the dust suction pipe, and the dust is trapped in the dust suction pipe, thereby reducing the amount of dust in the air in front of the tunneling device. During the operation of the device, larger ore will enter the dust suction pipe through the opening on the right side of the dust suction pipe, which will cause the dust suction pipe to be easily blocked and needs to be improved.
