When in use, the air in the ventilation tube enters the air outlet tube under the blocking of the collecting plate, and then the driving motor can drive the driving rod, and the driving rod blows the incoming air outward through the fan blades, and enters the mine after being filtered by the filter screen. At the same time, the driving rod will drive the cleaning brush to clean the outside of the filter screen, and the push rod will push the dust on the inside of the filter screen into the collecting tank, and then the push plate can be pulled to remove the dust, thereby avoiding clogging of the filter screen and affecting ventilation.

[0004] In actual operation, the ventilation fans in mine tunnels are mainly static and cannot adjust their angles. This design cannot properly adjust the ventilation angle according to the specific conditions of the mine tunnels.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] A coal mine tunnel ventilation device comprises a mounting base plate 1, the top of the mounting base plate 1 is fixedly connected to a support arm 11, the top of the support arm 11 is fixedly connected to a mounting top plate 2, and the bottom of the mounting top plate 2 is provided with a tunnel ventilation angle convenient adjustment mechanism 3.

[0028] In this embodiment: Under normal circumstances, the publication number "CN217632538U" discloses a ventilation device for coal mine tunnels. In actual operation, the ventilation fans of mine tunnels are mainly static and cannot be adjusted in angle. This design cannot properly adjust the ventilation angle according to the specific conditions of the mine tunnels. Due to the complex terrain of the mine tunnels, especially at the bends of the tunnels, the fans cannot be effectively adjusted in angle due to terrain restrictions, and thus cannot accurately control the direction of wind transmission. The ventilation efficiency needs to be further improved. By adding a convenient adjustment mechanism 3 for the tunnel ventilation angle, the wind direction angle can be adjusted during the installation of the fan for tunnel ventilation after the installation is completed, so as to better adapt to the complex tunnel environment and improve the ventilation effect of the tunnel.

[0029] like Figure 1-Figure 4 As shown;

[0030] Based on the existing coal mine tunnel ventilation device, by adding a convenient tunnel ventilation angle adjustment mechanism 3, it is possible to solve the problem that the ventilation fan in the mine tunnel is mainly static and cannot adjust the angle. This design cannot properly adjust the ventilation angle according to the specific conditions of the mine tunnel. Due to the complex terrain of the mine tunnel, especially at the bends of the tunnel, due to terrain restrictions, the fan cannot be effectively adjusted in angle, and thus the direction of wind transmission cannot be accurately controlled. The ventilation efficiency needs to be further improved.

[0031] More specifically:

[0032] In combination with the above content, in order to adjust the wind direction angle after the installation of the fan for tunnel ventilation is completed, so as to better adapt to the complex tunnel environment and improve the ventilation effect of the tunnel, a convenient tunnel ventilation angle adjustment mechanism 3 is provided at the bottom of the installation top plate 2. The convenient tunnel ventilation angle adjustment mechanism 3 includes a driving motor 31, a rotating bottom plate 32, a mounting frame 33, a fan 34 and a positioning assembly 35. The driving motor 31 is installed on the top of the installation top plate 2, and the output end of the driving motor 31 passes through the top of the installation top plate 2 and is fixedly connected to the top of the rotating bottom plate 32.
