[0020] 1. This dust suppression device for coal mine crushing equipment, through its atomizing spray assembly, can be installed at the feed inlet of the coal mine crushing equipment. By activating the second servo motor, a water pump and an exhaust fan can be driven simultaneously via a belt and pulley. The water pump, in conjunction with the atomizing nozzles, can spray dust at the inlet of the coal mine crushing equipment, while the exhaust fan can remove dust at the outlet. This prevents dust from splashing during coal crushing operations, effectively improving the cleanliness of the working environment and increasing crushing efficiency.

[0021] 2. The dust suppression equipment used in coal mine crushing devices can drive the lead screw to rotate through the first servo motor, so that the cleaning component can be threadedly connected to the lead screw. At this time, the cleaning component can drive the brush to move, and the brush can clean the atomizing nozzle, which can prevent the atomizing nozzle from being blocked and affecting the water spraying.

[0022] 3. This dust suppression equipment for coal mine crushing devices, through its filter screen, can filter large volumes of coal and dust when the exhaust fan is used for dust removal. The dust is collected in the inner cavity of the collection bucket. Through the first connecting rod, when it rotates, it drives the arc-shaped contact block to rotate. When the arc-shaped contact block moves to the first adapter groove, the first spring can push the arc-shaped contact block into the inner cavity of the first adapter groove. At this time, it drives the first processing component to vibrate, thereby automatically cleaning the filter screen and preventing the filter screen from becoming clogged.

[0023] 4. This dust suppression device for coal mine crushing equipment can drive the scraper to rotate via a connecting shaft, thereby scraping off the dust and debris accumulated on the inner wall of the collection bucket, facilitating cleaning of the collection bucket. Through the setting of contact blocks, after the contact blocks come into contact with the scraper, the automatic feeding component can be flipped to the bottom, allowing the debris in the inner cavity of the collection bucket to flow out. This structure can automatically clean the collected dust and clean the inner wall of the collection bucket.

[0024] 5. The dust suppression equipment used in coal mine crushing devices can limit and restrict the movement trajectory of the contact block through the set second adapter groove. At the same time, through the set second spring and torsion shaft, after the scraper disengages from the contact block, it can drive the automatic feeding component to reset, and can re-cover the bottom of the atomizing spray component.

A brush 8 is installed on the outer wall of the cleaning component 7, and the back of the brush 8 is attached to the outer wall of the atomizing nozzle 2. A belt 12 is installed in the inner cavity of the drive component 9, and pulleys 11 are installed at both ends of the inner cavity of the belt 12. A second servo motor 10 is installed on the outer wall of the drive component 9. The second servo motor 10 is installed on the outer wall of the left pulley 11 through the second rotating shaft. The left pulley 11 is used to drive the water pump 3, and the right pulley 11 is used to drive the exhaust fan 13.

[0035] The atomizing spray assembly 1 can be installed at the feed inlet of the coal mine crushing device. By starting the second servo motor 10, the water pump 3 and the exhaust fan 13 can be driven simultaneously through the belt 12 and pulley 11. The water pump 3, in conjunction with the atomizing nozzle 2, can spray dust at the inlet of the coal mine crushing device. The exhaust fan 13 can remove dust at the outlet of the coal mine crushing device. This can prevent dust from splashing during coal crushing, effectively improve the cleanliness of the working environment, and effectively improve the crushing efficiency.

[0036] The first servo motor 6, driven by the drive unit, can rotate the lead screw 5, so that the cleaning component 7 can be threadedly connected to the lead screw 5. At this time, the cleaning component 7 can drive the brush 8 to move, and the brush 8 can clean the atomizing nozzle 2, which can prevent the atomizing nozzle 2 from being blocked and affecting the water spraying.

[0037] like Figure 1 , Figure 3 , Figure 4 , Figure 5As shown, a dust suppression device for a coal mine crushing unit includes an exhaust fan 13 mounted on the other side of a drive assembly 9.

The other end of the corrugated pipe 16 is installed on the outer wall of the collection bucket 14, and the corrugated pipe 16 communicates with the inner cavity of the collection bucket 14.

[0038] The filter 17, when the exhaust fan 13 is used for dust removal, can filter large volumes of coal and dust, and collect the dust in the inner cavity of the collection bucket 14. The first connecting rod 18, when rotated, will drive the arc-shaped contact block 23 to rotate. When the arc-shaped contact block 23 moves to the first adapter groove 19, the first spring 21 will push the arc-shaped contact block 23 into the inner cavity of the first adapter groove 19. At this time, the first processing component 15 will vibrate, thereby automatically cleaning the filter 17 and preventing the filter 17 from becoming clogged.

[0039] like Figure 1 , Figure 6 , Figure 7As shown, a dust suppression device for a coal mine crushing unit includes a scraper 26 rotatably connected to the inner cavity of a collection bucket 14. An automatic feeding assembly 27 is movably connected to the bottom of the inner cavity of the collection bucket 14. Contact blocks 29 are symmetrically and movably connected to the left sides of both ends of the automatic feeding assembly 27. A connecting shaft 25 is installed in the inner cavity of the collection bucket 14, and the connecting shaft 25 is connected to two first connecting rods 18 and an exhaust fan 13. There are three scrapers 26, and the opposite sides of the three scrapers 26 are all attached to the inner cavity of the collection bucket 14. A torque shaft 28 is installed on the right side of the automatic feeding assembly 27, and the torque shaft 28 is installed in the atomizing spray. On the right side of the inner cavity of component 1, the left sides of both ends of the automatic feeding component 27 are symmetrically provided with second adapter grooves 33. The left side of the contact block 29 is inclined. An elastic band 30 is installed at the bottom of the contact block 29. A movable block 31 is installed at the bottom of the elastic band 30. A second spring 32 is installed at the bottom of the movable block 31. The bottom of the second spring 32 is installed at the bottom of the inner cavity of the collection bucket 14. The movable block 31 is movably connected to the bottom of the inner cavity of the collection bucket 14. The elastic band 30 is installed in the inner cavity of the collection bucket 14. The movable rod of the movable block 31 near the automatic feeding component 27 is connected to the inner cavity of the second adapter groove 33.

[0040] The connecting shaft 25 can drive the scraper 26 to rotate, thereby scraping off the dust and debris accumulated on the inner wall of the collection bucket 14, making it easier to clean the collection bucket 14. The contact block 29 can flip the automatic feeding component 27 to the bottom after it contacts the scraper 26, so that the debris in the inner cavity of the collection bucket 14 can flow out of the inner cavity of the collection bucket 14. This structure can automatically clean the collected dust and clean the inner wall of the collection bucket 14.

[0041] The second adapter slot 33 can limit and restrict the movement trajectory of the contact block 29. At the same time, the second spring 32 and the torque shaft 28 can drive the automatic feeding component 27 to reset after the scraper 26 disengages from the contact block 29, so that the bottom of the atomizing spray component 1 can be covered again.

[0042] It should be noted that this invention is a dust suppression device for a coal mine crushing device. In use, the atomizing spray assembly 1 is installed at the feed inlet of the coal mine crushing device, and the first processing assembly 15 is installed at the discharge outlet of the coal mine crushing device. The water pump 3 is connected to the water supply pipe. The second servo motor 10 is started, which drives the drive assembly 9 and the pulley 11 to rotate. After the pulley 11 on the left rotates, it drives the water pump 3. The water pump 3 sprays water through the atomizing nozzle 2 towards the feed inlet of the coal mine crushing device, thereby achieving dust suppression spraying. The first servo motor 6 is started, which drives the lead screw 5 to rotate in the inner cavity of the movable groove 4, so that the bottom of the cleaning assembly 7 can be threadedly connected to the lead screw 5. At this time, the brush 8 can be moved on the outer wall of the atomizing nozzle 2. After the movement, the atomizing nozzle 2 can be cleaned, which can prevent the atomizing nozzle 2 from becoming blocked.

[0043] The pulley 11 on the right side will drive the exhaust fan 13 to rotate. When the exhaust fan 13 rotates, it will remove dust and drive the first connecting rod 18 and the connecting shaft 25 to rotate. When the first connecting rod 18 rotates, it can drive the first processing component 15 to vibrate in conjunction with the arc-shaped contact block 23, thereby shaking off the dust accumulated on the filter screen 17, so that the filter screen 17 can be cleaned.

[0044] When the connecting shaft 25 rotates, it will drive the scraper 26 to rotate. The scraper 26 can clean the inner wall of the collection bucket 14. After the scraper 26 contacts the contact block 29, it will drive the automatic feeding component 27 to press down through the movable block 31, so that the dust in the inner cavity of the collection bucket 14 can be discharged. When the scraper 26 disengages from the contact block 29, the automatic feeding component 27 can be automatically reset through the torque shaft 28 and the second spring 32.
