[0002] A coal mine is an area where humans exploit coal resources in coal-rich mining areas. It usually includes tunnels, shafts, and mining faces. Coal mines can be divided into underground coal mines and open-pit coal mines according to different mining methods. Underground coal mines are suitable for situations where the coal seam is far from the surface. Coal is mined by digging tunnels underground. Fans are usually needed for ventilation in coal mines.

[0003] A coal mine ventilation adjustment device is disclosed in the utility model patent with publication number CN213392226U, including a movable plate, a limiting block is fixedly connected to the back of the movable plate, a rotating shaft is sleeved inside the movable plate, an adjusting plate is sleeved on the surface of the rotating shaft, one end of the adjusting plate is threadedly connected to a limiting nut through a threaded column, an adjusting ring is movably connected to the surface of the limiting nut, one end of the adjusting ring is fixedly connected to a fixed block, and a fastening bolt is threadedly connected to the internal thread of the fixed block. The utility model can limit the connection between the adjusting plate and the adjusting ring through the action of the limiting nut, and can drive the adjusting plate to move by moving the limiting nut. The rotating angles of the movable plate and the adjusting plate can be adjusted according to the needs of the staff, so that the ventilation flow rate can be adjusted, which is convenient for the staff to use.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the ventilation adjustment device is in use, the ventilation flow is adjusted by an adjustment plate, and the adjustment plate on the device will overlap in front of the blades when stored. Therefore, the blades will block the air duct to a certain extent, resulting in poor use effect.

[0005] Therefore, those skilled in the art have proposed a coal mine ventilation adjustment device to solve the problems raised by the background technology. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a coal mine ventilation adjusting device to solve the problem that the ventilation adjusting device in the prior art adjusts the ventilation flow rate through an adjusting plate when in use, and the adjusting plate on the device will overlap in front of the blade when stored. Therefore, the blade will block the air duct to a certain extent, resulting in poor use effect.

[0007] A coal mine ventilation adjustment device comprises a cap, a mounting frame welded to the upper end of the cap, a first connecting block and a second connecting block welded to the inner side wall of the mounting frame, a first plug hole provided in the first connecting block, a second plug hole provided in the second connecting block, a fan body installed between the first connecting block and the second connecting block, and a rectangular frame provided at the front end surface of the mounting frame, wherein a mounting assembly for mounting the fan body with the rectangular frame is provided in the mounting frame, and an adjustment assembly for adjusting the width of the air duct of the fan body is provided in the rectangular frame;

When the width of the air duct needs to be adjusted, the threaded rod can be driven to rotate by starting the servo motor. The two oppositely arranged threads on the surface of the threaded rod can drive the two sliders to move relative to each other when the threaded rod rotates. In this way, the air duct can be blocked by the baffle, and the width of the air duct can be adjusted conveniently. By completely removing the baffle from the front end of the fan body, the influence of the baffle on the air duct of the fan body can be reduced, making it more convenient to use.

[0011] Preferably, two symmetrically arranged mounting grooves are provided at the lower end of the baffle, and rollers are rotatably connected in the mounting grooves, and the rollers are in contact with the inner bottom surface of the rectangular frame.

At this time, the baffle is in a vertical state, which can block the transverse air duct of the fan body, that is, the effect of adjusting the transverse air duct of the fan body can be achieved. After the second plug rod is pulled out of the second plug hole, the rectangular frame is rotated. At this time, the two connecting rods move in the installation frame. When the rectangular frame is adjusted to a vertical state, the two baffles are respectively located above and below the front end surface of the fan body, so that the longitudinal air duct of the fan body can be blocked conveniently, and the longitudinal air duct of the fan body can be changed conveniently.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0027] The adjustment assembly includes a slide groove 201 provided on the top wall of the rectangular frame 2 , two symmetrically arranged sliders 202 slidably connected to the slide groove 201 , and a baffle 205 fixedly connected to the lower ends of the two sliders 202 .

[0028] The rectangular frame 2 includes a servo motor 203 installed at one end thereof and a threaded rod 204 installed at the output end of the servo motor 203 . Two sets of threads are symmetrically arranged on the circumference of the threaded rod 204 , and the threaded rod 204 is threadedly connected to the two sliders 202 respectively.

[0029] As can be seen from the above, when in use, by placing the device in a coal mine and starting the fan body 104, ventilation can be provided into the coal mine. When the width of the air duct needs to be adjusted, the threaded rod 204 can be driven to rotate by starting the servo motor 203. The two oppositely arranged threads on the surface of the threaded rod 204 can drive the two sliders 202 to move relative to each other when the threaded rod 204 rotates, so that the air duct can be blocked by the baffle 205, and the width of the air duct can be adjusted conveniently. By completely removing the baffle 205 from the front end of the fan body 104, the influence of the baffle 205 on the air duct of the fan body 104 can be reduced, making it more convenient to use.

[0030] Embodiment 2: Based on embodiment 1, two symmetrically arranged mounting grooves 206 are provided at the lower end of the baffle 205 , and rollers 207 are rotatably connected in the mounting grooves 206 , and the rollers 207 are in contact with the inner bottom surface of the rectangular frame 2 .

[0033] A second plug rod 209 is slidably connected to the inner side wall of the lower end of the rectangular frame 2 , and the position of the second plug rod 209 corresponds to the position of the second plug hole 1031 .

[0034] As can be seen from the above, when in use, the second plug rod 209 is inserted into the second hole 1031. At this time, the baffle 205 is in a vertical state, which can block the transverse air duct of the fan body 104, that is, the effect of adjusting the transverse air duct of the fan body 104 can be achieved. After the second plug rod 209 is pulled out of the second hole 1031, the rectangular frame 2 is rotated. At this time, the two connecting rods 105 move in the installation frame 101. When the rectangular frame 2 is adjusted to a vertical state, the two baffles 205 are respectively located above and below the front end surface of the fan body 104, so that the longitudinal air duct of the fan body 104 can be blocked conveniently, and the longitudinal air duct of the fan body 104 can be changed conveniently.
