More specifically, the automatic drill carriage for coal mine further comprises a control device 200, the control device 200 receives the signals collected by the collecting device 100 to make a judgment, and then a control signal is transmitted to control the closing or opening of the clutch control electromagnetic valve 300, so that the power distribution of the automatic drill carriage for coal mine is controlled, when the clutch is in an open state, all the output power of the engine is used for the movement of the automatic drill carriage, and further an operator can operate the drill carriage to quickly escape from a dangerous place when the dangerous situation occurs in coal mine operation.
In a specific embodiment, the status signal of the automatic drill carriage for the coal mine comprises an air inlet oxygen concentration signal of the automatic drill carriage for the coal mine. Wherein the control device 200 transmits a control signal to the clutch control solenoid valve 300 according to an air inlet oxygen concentration signal of the automatic drill carriage for the coal mine.
