[0022] The present invention provides a mine ventilation device with adjustable air volume. Figure 1-4 As shown, the mine ventilation device with adjustable air volume includes: a ventilation pipe 1, which is used to ventilate the mine; a mounting shaft 2 rotatably installed in the ventilation pipe 1, and a plurality of ventilation fan blades 3 are fixedly installed on the mounting shaft 2, and the ventilation fan blades 3 are used to ventilate the ventilation pipe 1; a drive shaft 4 rotatably installed on the ventilation pipe 1, and a first bevel gear 5 is fixedly sleeved on the drive shaft 4 and the mounting shaft 2, and the two first bevel gears 5 are meshed with each other; a drive motor 6 fixedly installed at the bottom of the ventilation pipe 1, and the output shaft of the drive motor 6 is fixedly connected to one end of the drive shaft 4; a filter 7 fixedly installed in the ventilation pipe 1, and the filter 7 is used to filter impurities in the air; two adjustment mechanisms provided on the ventilation pipe 1, and the adjustment mechanisms are used to adjust the ventilation volume of the ventilation pipe 1; a cleaning mechanism installed on the ventilation pipe 1, and the cleaning mechanism is used to clean dust on both sides of the filter 7; a discharge mechanism installed on the ventilation pipe 1, and the discharge mechanism is used to discharge dust cleaned from the filter 7 by the cleaning mechanism into the ventilation pipe 1.

[0023] In this embodiment, when ventilating the mine, the ventilation pipe 1 and the corresponding ventilation connecting pipe of the mine are connected. During ventilation, the driving motor 6 is started by the controller to drive the driving shaft 4 to rotate. Under the action of the first bevel gear 5, the ventilation fan blades 3 on the mounting shaft 2 are driven to rotate. The rotating ventilation fan blades 3 can ventilate the ventilation pipe 1, thereby ventilating the mine and ensuring the air circulation in the mine. At the same time, when the ventilation volume in the ventilation pipe 1 needs to be adjusted, the adjustment mechanism on the right side of the ventilation pipe 1 is in a fully open state, and the ventilation volume in the ventilation pipe 1 is adjusted by the adjustment mechanism on the left side of the ventilation pipe 1, so as to better meet the actual ventilation needs of the mine. During ventilation, impurities in the air can be filtered through the filter 7, thereby improving the cleanliness of the mine ventilation.

[0024] When the filter 7 has been used for a certain period of time and needs to be cleaned, the two regulating mechanisms are activated by the controller to close the ventilation pipe 1, and then the cleaning mechanism is activated by the controller, so that the dust and impurities filtered on both sides of the filter 7 can be cleaned. During cleaning, since the two regulating mechanisms close the ventilation pipe 1, the cleaned dust cannot fly to both sides of the ventilation pipe 1. During cleaning, the discharge mechanism is activated by the controller, and the dust cleaned from the filter 7 is discharged from the ventilation pipe 1 through the discharge mechanism, thereby completing the cleaning of the filter 7. After cleaning, the two regulating mechanisms are activated by the controller to open the ventilation pipe 1 for normal ventilation operation. At the same time, the operation of the regulating mechanism, the cleaning mechanism and the discharge mechanism can be set by the controller, and the impurities filtered on the filter 7 can be cleaned regularly. The mine can be ventilated through the entire device, and the ventilation volume can be adjusted according to actual needs to better meet the actual ventilation needs of the mine.

At the same time, when the filter 7 needs to be cleaned, the controller starts the two power motors 8 at the same time to drive the adjustment plates 10 on the two rotating shafts 9 to rotate, completely blocking the ventilation pipe 1, so that the cleaned dust cannot fly to the two sides of the ventilation pipe 1. On the one hand, it is convenient for the discharge mechanism to discharge the cleaned dust out of the ventilation pipe 1, and on the other hand, it prevents the cleaned dust from entering the mine.

[0030] In this embodiment, when the driving mechanism is used, the controller starts the servo motor 16, and under the interaction of the sprocket 17 and the chain 18, the two connecting shafts 14 are driven to rotate. Under the action of the second bevel gear 15, the two brush plates 13 on the two placement shafts 12 are driven to rotate.
