[0027] The present invention provides an automatic dust cleaning device with a pulse spraying function. Figure 1-6As shown, it includes a barrel box 1, and the airflow flows from bottom to top in the barrel box 1. A plurality of rectangular frames 5 are fixedly inserted inside the barrel box 1, and a dust filter cloth 2 is fixedly inserted inside each rectangular frame 5. Storage bins 12 are provided on the inner walls on the left and right sides of the barrel box 1. The storage bins 12 are located below the rectangular frames 5. An ash storage box 3 is provided inside the barrel box 1 and between the two storage bins 12. The inner and outer wall widths of the rectangular frames 5 are respectively equal to the inner and outer wall widths of the ash storage box 3. Baffles 18 are slidably inserted inside the two storage bins 12. The sides of the two baffles 18 that are away from each other are fixedly connected with spring telescopic rods 19. The spring telescopic rods 19 are connected to the barrel box 11. The other end of the retractable rod 19 is fixedly passed through the inner wall of the corresponding storage bin 12. After the ash box 3 moves out of the storage bin 12, the spring telescopic rod 19 pushes the baffle 18 to be flush with the left and right inner walls of the barrel box 1. The upper surface of the ash box 3 slides in contact with the bottom surface of the rectangular frame 5. The inner wall width of the storage bin 12 is equal to the outer width of the ash box 3.

[0028] A reciprocating screw rod 6 is provided inside the ash storage box 3, and the front and rear ends of the reciprocating screw rod 6 rotate and penetrate the front and rear inner walls of the ash storage box 3. The reciprocating screw rod 6 is located inside the ash storage box 3 and is slidably connected with an ash pushing frame 7. The ash pushing frame 7 can move forward and backward by engaging with the rotating reciprocating screw rod 6. The upper end of the ash pushing frame 7 is slidably connected with an ash scraper plate 8, and the bottom surface of the ash scraper plate 8 is fixedly connected with a push spring 9, and the other end of the push spring 9 is fixedly connected to the ash pushing frame 7. The left and right ends of the upper surface of the scraper plate 8 are both beveled, and the left and right edges of the lower end of the rectangular frame 5 are both rounded. When the ash storage box 3 moves left and right, the beveled end of the scraper plate 8 gradually compresses the push spring 9 by contacting with the arc edge of the rectangular frame 5, so that the scraper plate 8 is retracted into the ash pushing frame 7.

[0029] The front and back sides of the ash storage box 3 are both provided with ash discharge grooves 10 connected to the interior thereof. When the ash storage box 3 is separated from the storage bin 12, the front and rear inner walls of the barrel box 1 can block the ash discharge grooves. The front and rear inner walls of each storage bin 12 are both provided with ash discharge grooves 11 connected to the outside.

The missing tooth gear A14 is located behind the missing tooth gear B17. The parameters of the missing tooth gear A14 are the same. The tooth range of the missing tooth gear B17 is less than half a circle. The missing tooth gear A14 and the missing tooth gear B17 are alternately meshed with the full gear 15 and the tooth plate 16. When the missing tooth gear B17 meshes with the tooth plate 16 once, it drives the ash storage box 3 to move from under one rectangular frame 5 to under another rectangular frame 5. After the missing tooth gear B17 is disengaged from the tooth plate 16, the missing tooth gear A14 meshes with the full gear 15 once, and the full gear 15 drives the reciprocating screw rod 6 to rotate once. The ash pushing frame 7 moves back and forth once by meshing with the rotating reciprocating screw rod 6. When the scraper plate 8 cleans the dust filter cloth 2 above, the dust filter cloth 2 in the rectangular frames 5 at other positions continues to filter the dust carried by the airflow.

[0031] Working principle: the pulse airflow drives the dust to flow from bottom to top in the barrel box 1, the dust filter cloth 2 filters the passing airflow, and the motor 13 is started to drive the missing tooth gear A14 and the missing tooth gear B17 to rotate, so that the missing tooth gear A14 and the missing tooth gear B17 are alternately meshed with the full gear 15 and the tooth plate 16. When the missing tooth gear B17 is meshed with the tooth plate 16 once, the ash storage box 3 is driven to move from under one rectangular frame 5 to under another rectangular frame 5. After the missing tooth gear B17 is disengaged from the tooth plate 16, the missing tooth gear A14 is meshed with the full gear 15 once. The ash pushing frame 7 moves back and forth once, and the push spring 9 pushes the scraper plate 8 to contact the bottom surface of the dust filter cloth. When the ash pushing frame 7 moves, it drives the scraper plate 8 to scrape and clean the dust filter cloth, so that the dust falls into the ash storage box 3. When the ash storage box 3 enters the storage bin 12, the ash outlet trough 10 is connected with the ash discharge trough 11. When the ash pushing frame 7 moves back and forth, the dust can be pushed from the ash outlet trough 10 and the ash discharge trough 11 into the arc-shaped connecting pipe 21, and then the dust falls into the ash collecting box 20.
