[0030] See also Figures 1 to 9 In an embodiment of the utility model, a coal mine ventilation device for eliminating ash slag blockage comprises:

[0031] A housing 1, wherein an erasing mechanism is disposed in the housing 1, wherein the erasing mechanism comprises a driving assembly and a pipe wall scraping assembly, wherein the pipe wall scraping assembly comprises a scraping member slidably disposed in the housing 1, and wherein the driving assembly can drive the scraping member to reciprocate along the length direction of the housing 1, thereby erasing the inner wall of the housing 1;

[0032] The driving assembly includes a motor 102, the motor 102 is fixedly connected to a mounting member 103 fixedly disposed in the housing 1, and the output shaft of the motor 102 is coaxially fixedly connected to the rotating shaft of the fan 3 rotatably mounted on the mounting member 103;

[0033] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 After the motor 102 enters the working state, the output shaft that continuously rotates in the same direction will drive the fan 3 to continuously rotate in the same direction. Subsequently, the fan 3 that continuously rotates in the same direction will bring the air in the coal mine into the casing 1 through the air inlet grille 101, and then be discharged from the motor 102, thereby achieving the effect of continuing ventilation of the coal mine.

[0034] The pipe wall scraping assembly further comprises a driving shaft 4, one end of which is coaxially fixedly connected to the rotating shaft of the fan 3, and the other end of which is rotatably connected to a supporting frame 9 fixedly disposed in the housing 1;

[0035] The scraper member includes a movable sleeve 7 sleeved on the drive shaft 4, a protrusion 701 is formed on the inner wall of the movable sleeve 7, the protrusion 701 is slidably arranged in an annular groove 401 provided on the drive shaft 4, and a scraper plate 2 is fixedly arranged on the movable sleeve 7;

[0036] For details, please refer to Figure 3 , Figure 4 , Figure 5 The scraper plate 2 is arranged in a rectangular structure that fits the inner wall of the outer shell 1. When the motor 102 continues to rotate in the same direction, the drive shaft 4 will rotate synchronously with the output shaft of the motor 102. At this time, the movable sleeve 7 sleeved on the drive shaft 4 will reciprocate along the axial direction of the drive shaft 4 with the cooperation of the protrusion 701 and the annular groove 401. During the movement of the movable sleeve 7, the scraper plate 2 fixed to the movable sleeve 7 will reciprocate and scrape the inner wall of the outer shell 1, so that the dust entering through the air inlet grille 101 will not adhere to the inner wall of the outer shell 1, thereby reducing the possibility of dust accumulation in the outer shell 1.

[0037] For further information, please refer to Figure 6 , Figure 7 , Figure 8 , Fig. 9, a coal mine ventilation device for eliminating ash blockage, a cleaning component, arranged in the shell 1, including a reciprocating structure arranged in the shell 1, the reciprocating structure including a reciprocating member arranged along the width direction of the shell 1, the reciprocating member is connected to a wiping member slidably arranged in the shell 1, when the reciprocating structure drives the reciprocating member to reciprocate along the width direction of the shell 1, the wiping member can wipe the air inlet grille 101 of the shell 1;

[0038] The reciprocating structure includes two sets of toothed wheels 12 rotatably mounted on the support frame 9, a toothed belt 5 is arranged between the two sets of toothed wheels 12, the toothed belt 5 is meshed with a gear 6 coaxially fixedly arranged on the drive shaft 4, and a protruding column 501 is fixedly arranged on the side of the toothed belt 5 away from the support frame 9;

[0039] The reciprocating member includes a reciprocating plate 10 slidably arranged along the width direction of the housing 1, and a sliding groove 1001 is provided on a side of the reciprocating plate 10 away from the air inlet grille 101;

[0040] The wiping member comprises a moving plate 11 fixedly connected to the reciprocating plate 10, and a plurality of groups of wiping plates 1101 cooperating with the air inlet grille 101 are equidistantly arranged on one side of the moving plate 11 away from the reciprocating plate 10 along its length direction;

[0041] For details, please refer to Fig. 9 The above-mentioned movable plate 11 is fixedly connected to the reciprocating plate 10 through a connecting plate, and a through groove 1102 is opened on the connecting plate. A guide rod 8 is fixedly arranged in the through groove 1102. With the cooperation between the guide rod 8 and the through groove 1102, the reciprocating plate 10 and the movable plate 11 can only reciprocate along the width direction of the shell 1.

[0042] For details, see Figure 6 , Figure 7 , Figure 8 , Fig. 9 The air inlet grilles 101 are arranged in multiple groups equidistantly in the opposite direction along the length of the movable plate 11, and correspondingly, the number of the wiping plates 1101 is the same as the number of the air inlet grilles 101;

[0043] In combination with the above, when the driving shaft 4 is driven by the motor 102 to rotate continuously in the same direction, the gear 6 coaxially fixed with the driving shaft 4 will drive the toothed belt 5 to rotate continuously in the same direction, and when the toothed belt 5 rotates continuously in the same direction, the protrusion 501 fixed on the toothed belt 5 will continue to slide in the slide groove 1001, and at the same time drive the reciprocating plate 10 to continue to reciprocate along the length direction of the guide rod 8. At this time, the movable plate 11 fixedly connected to the reciprocating plate 10 will drive the wiping plate 1101 to wipe the air inlet grille 101 reciprocatingly, so that dust will not accumulate on the air inlet grille 101, thereby preventing the ventilation efficiency from being reduced due to blockage of the air inlet.
