| titleOfInvention | A kind of coal mine tunnel opening excavation equipment |
| abstract | The utility model provides a coal mine tunnel opening excavation equipment, which comprises a main body component, a detection component and a dust removal component, and a detection component and a dust removal component are arranged above the main body component; the main body component comprises a frame, a cutting mechanism, a first a casing and a traveling mechanism; a first casing is arranged above the frame, and a cutting mechanism is installed on the upper surface of the frame; the utility model transmits a signal when the methane sensor detects that the methane concentration is too high The PLC controller turns on the motor and the water pump at the same time. The output shaft of the motor drives the second housing to rotate through the second bevel gear and the first bevel gear in conjunction with the first rod body, and the water in the second housing is extracted through the water pump. From the water outlet through the three-way valve, the first pipe body is rotated and sprayed from the spray head, so that the methane cannot be accumulated in the air, thereby reducing the content of methane, and at the same time reminding the operator of the rupture of the gas pipe, and timely maintenance, thus reducing the safety. The probability of a hazard occurring. |
