Abstract
The utility model relates to the technical field of coal mine ventilation, in particular to a full-coverage underground ventilation blind area eliminating device which comprises a base, four traveling wheels are fixedly connected to the bottom face of the base, a storage device is arranged in the base, a draught fan body is operated to pressurize air communicated with a ventilation pipeline, and the air is conveyed into a connecting pipe from the end of an air outlet pipe. Finally, air is blown into the mine through a telescopic device, the telescopic device can extend through an organ air guide pipe, a user only needs to take down a corresponding locking bolt to enable a fixing rod to slide out of a butt joint groove, and then the user can hold a handle to operate an air blowing opening to conduct ventilation and air blowing on some dead corners in the mine independently; and the two damping bearings fixedly connected to the connecting pipe can enable the whole air distribution device to rotate, the direction of the telescopic device is changed, the ventilation and air blowing angle and direction of the device are increased, ventilation dead angles are greatly reduced, and the technical problem that an existing device has some blind areas during ventilation, and ventilation cannot be achieved is solved.
