DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

After the dust and iron filings enter the dust box 14, the airflow passes through the filter screen 16 and is discharged to the outside through the exhaust pipe 15, while the dust and iron filings are blocked by the filter screen 16. The dust and iron filings in the airflow are filtered by the filter screen 16, and the airflow generates an impact force on the first spiral impeller 17 and drives it to rotate. The rotation of the first spiral impeller 17 can cause the scraper 18 to scrape the side wall of the filter screen 16, and the dust attached to the side wall of the filter screen 16 is removed. The dust and iron filings are scraped off so that they do not block the filter screen plate 16. In this process, the grinding mechanism 11 can reduce the generation of a large amount of dust and iron filings floating in the air during rust removal, which makes it inconvenient to clean them, thereby causing certain safety hazards. At this time, the dust is sucked into the dust box 14 for collection through the dust suction pipe 19, thereby playing the role of cleaning and collecting the dust and iron filings during grinding by the grinding mechanism 11, and the first spiral impeller 17 and the scraper 18 can play the role of preventing the filter screen plate 16 from being blocked during filtering.

[0026] like Figure 4 , 5As shown, the inner side wall of the dust suction pipe 19 is provided with a mounting plate 2; the side wall of the mounting plate 2 is rotatably connected to a second spiral impeller 21; the second spiral impeller 21 penetrates the wall of the mounting plate 2 and is rotatably connected thereto; a pair of fixing plates 22 are fixedly connected to the end of the second spiral impeller 21; the fixing plates 22 are symmetrically arranged on both sides of the second spiral impeller 21 and have the same structure; a plurality of cleaning brushes 23 are evenly fixedly connected to the side wall of the fixing plate 22; a connecting rod 24 is fixedly connected to the side wall of the cleaning brush 23; the connecting rod 24 penetrates the wall of the cleaning brush 23 and is fixed thereto; when in use, during the process of vacuuming through the dust suction pipe 19, the airflow will generate a A certain impact force is exerted and it is driven to rotate. At this time, the cleaning brush 23 can be used to clean the inner wall of the dust suction tube 19, and the dust attached to the inner wall of the dust suction tube 19 can be swept away. At the same time, during the cleaning process of the cleaning brush 23, multiple cleaning brushes 23 can be fixedly connected together through the connecting rod 24, so that they can be concentrated during the cleaning process to improve the cleaning effect. In this process, the dust suction tube 19 can be reduced after long-term use, resulting in dust adhering to the inner wall of the dust suction tube 19, which is prone to accumulation over time and affects the dust suction effect. At this time, the dust is swept away by the cleaning brush 23, thereby playing a dust removal role on the dust attached to the inner wall of the dust suction tube 19 when the dust suction tube 19 is in use.

[0027] like Figure 3 As shown, the side wall of the scraper 18 is fixedly connected to a magnetic block 3; the inner side wall of the exhaust pipe 15 is fixedly connected to a plurality of elastic rods 31; the end of the elastic rod 31 is fixedly connected to a magnetic ball 32; the magnetic block 3 and the magnetic ball 32 are magnetically connected; when in use, the scraper 18 rotates, and the magnetic block 3 is rotated to correspond to the position of the magnetic ball 32, and the two will produce an attraction, so that the magnetic ball 32 can be pulled to one side of the magnetic block 3, and the elastic rod 31 will be deformed to a certain extent by the tension, and at this time, the magnetic ball 32 will impact the wall of the filter screen plate 16, and the vibration generated by the impact can be used to The dust and iron filings on the side wall of the filter plate 16 are vibrated off, and then when the magnetic block 3 turns away from the magnetic ball 32, the elastic force of the elastic rod 31 will drive the magnetic ball 32 to reset. In this process, the cleaning effect of the scraper 18 can be reduced, which makes it difficult to clean the dust in the holes of the filter plate 16, thereby affecting the ventilation effect of the filter plate 16 to a certain extent. At this time, the magnetic ball 32 is used to knock on the wall of the filter plate 16, thereby playing a cleaning role for the dust attached to the holes of the filter plate 16, and further increasing the anti-clogging effect of the filter plate 16 when in use.

[0028] like Figure 4-6As shown, a pair of slide rails 4 are fixedly connected to the inner wall of the dust suction tube 19; the slide rails 4 are symmetrically arranged on both sides of the dust suction tube 19 and have the same structure; the inner wall of the slide rail 4 is slidably connected with an insert block 41; the side wall of the insert block 41 is fixedly connected with a rubber pad 42; the insert block 41 is fixedly connected to the mounting plate 2; when in use, the staff holds the second spiral impeller 21 and inserts the insert block 41 into the slide rail 4. At this time, a certain friction force will be generated due to the contact between the rubber pad 42 and the slide rail 4, and the insert block 41 is fixed, so that the installation of the second spiral impeller 21 can be completed. In this process, the cleaning brush 23 can be reduced after long-term use, which may cause it to break and be damaged, affecting the cleaning effect. At this time, the insert block 41 is inserted into the slide rail 4 for fixing, thereby facilitating the removal and replacement of the cleaning brush 23.

[0029] like Figure 4 , 5 As shown, the side wall of the fixing plate 22 is fixedly connected with an elastic sheet 5; the side wall of the dust suction pipe 19 is evenly fixedly connected with a plurality of protrusions 51; when in use, the fixing plate 22 can be rotated to make the elastic sheet 5 hit the wall of the protrusion 51. At this time, under the continuous rotation of the fixing plate 22, a certain force can be applied to the elastic sheet 5, so that the elastic sheet 5 is deformed to a certain extent and separated from the side wall of the protrusion 51. Then, under the elastic action of the elastic sheet 5, it will shake and vibrate, and the dust and iron filings attached to the side wall of the cleaning brush 23 can be shaken off by the vibration. In this process, the cleaning brush 23 can be reduced in the process of long-term use, resulting in a large amount of dust and iron filings easily attached to the side wall of the cleaning brush 23, which is inconvenient to clean, thereby affecting the cleaning effect of the cleaning brush 23. At this time, the vibration effect generated by the elastic sheet 5 can be used to clean the dust and iron filings attached to the side wall of the cleaning brush 23.

[0030] like Figure 6 As shown, a pair of elastic plates 6 are symmetrically fixed to the side walls of the slide rail 4; the elastic plates 6 are arranged in an arc shape; when in use, when the plug block 41 is inserted into the slide rail 4, the plug block 41 will contact and squeeze the elastic plates 6 on both sides, and the elastic plates 6 can be squeezed to cause a certain deformation, and then the plug block 41 can be pushed to the middle of the slide rail 4 under the elastic force of the elastic plates 6, and at the same time, the plug block 41 will also slide to the middle of the elastic plates 6 on both sides, and finally inserted into the slide rail 4. In this process, it can reduce the difficulty of aligning the two when inserting the plug block 41 into the slide rail 4, making the insertion process more cumbersome. At this time, the elastic plate 6 is set to play a limiting role when the plug block 41 is inserted into the slide rail 4.

[0031] like Figure 3As shown, the side wall of the magnetic ball 32 is fixedly connected with a rubber sleeve 7; when in use, when the magnetic ball 32 collides with the wall of the filter screen plate 16, the rubber sleeve 7 can be used to block the magnetic ball 32 and the filter screen plate 16, and the impact force on the filter screen plate 16 can be reduced due to the flexibility of the rubber sleeve 7. In this process, the impact of the magnetic ball 32 on the wall of the filter screen plate 16 for a long time can be reduced, which can easily damage the filter screen plate 16 and affect its filtering effect. At this time, the rubber sleeve 7 is set to protect the filter screen plate 16 and increase its service life.

[0032] During operation, the grinding mechanism 11 is aligned with the surface of the ship, and then the grinding mechanism 11 is started to remove rust from the surface of the ship. During the rust removal, the dust suction fan 12 is started at the same time. At this time, the dust and iron filings generated by the grinding mechanism 11 during grinding can be sucked in through the dust suction pipe 19, and then transported into the dust collecting box 14 through the connecting pipe 13. After the dust and iron filings enter the dust collecting box 14, the airflow will pass through the filter plate 16 and be discharged to the outside through the exhaust pipe 15, while the dust and iron filings will be blocked by the filter plate 16. The dust and iron filings in the airflow are filtered by the filter plate 16, and the airflow will generate an impact force on the first spiral impeller 17 and drive it to rotate. The rotation of the first spiral impeller 17 can cause the scraper 18 to scrape the side wall of the filter plate 16. In addition, the dust and iron filings attached to the side wall of the filter plate 16 are scraped off so that they do not block the filter plate 16. When in use, during the process of vacuuming through the dust suction pipe 19, the airflow will generate a certain impact force on the second spiral impeller 21 and drive it to rotate. At this time, the inner wall of the dust suction pipe 19 can be cleaned by the cleaning brush 23 to sweep away the dust attached to the inner wall of the dust suction pipe 19. At the same time, during the cleaning process of the cleaning brush 23, multiple cleaning brushes 23 can be fixedly connected together by the connecting rod 24, so that they can be concentrated during the cleaning process to improve the cleaning effect. When in use, the scraper 18 rotates, and when the magnetic block 3 is rotated to the corresponding position with the magnetic ball 32, the two will have an attraction, so that the magnetic ball 32 can be moved to one side of the magnetic block 3. When the magnetic block 3 is pulled away from the magnetic ball 32, the elastic force of the elastic rod 31 drives the magnetic ball 32 to reset. When in use, the staff holds the second spiral impeller 21 and inserts the plug 41 into the slide rail 4. At this time, a certain friction force is generated by the contact between the rubber pad 42 and the slide rail 4, and the plug 41 is fixed, thereby completing the installation of the second spiral impeller 21. When in use, the elastic sheet 5 can hit the wall of the protrusion 51 through the rotation of the fixing plate 22. At this time, The fixed plate 22 continuously rotates to exert a certain force on the elastic sheet 5, causing the elastic sheet 5 to produce a certain deformation and detach from the side wall of the protrusion 51, and then the elastic sheet 5 will shake and vibrate under the elastic action of the elastic sheet 5, and the dust and iron filings attached to the side wall of the cleaning brush 23 can be shaken off by the vibration. When in use, when the plug block 41 is inserted into the slide rail 4, the plug block 41 will contact and squeeze the elastic plates 6 on both sides, and the elastic plates 6 can be squeezed to produce a certain deformation, and then the plug block 41 can be pushed to the middle of the slide rail 4 under the elastic force of the elastic plates 6, and the plug block 41 will also slide to the middle of the elastic plates 6 on both sides, and finally inserted into the slide rail 4. When in use, when the magnetic ball 32 hits the wall of the filter screen plate 16,The rubber sleeve 7 can be used to block the magnetic ball 32 and the filter screen plate 16, and the impact force on the filter screen plate 16 can be reduced due to the flexibility of the rubber sleeve 7.
