[0030] In this embodiment, the inner cavity of the mounting bracket 3 is hollow, and the air intake filter 4 is located at the opening on the front side of the mounting bracket 3. The opening on the front side of the mounting bracket 3 is precisely matched with the air intake filter 4, and the inner cavity of the mounting bracket 3 is connected to the inner cavity of the support base 1.

[0031] The drive motor 51 is fixed on the top of the mounting bracket 3. The output shaft of the drive motor 51 is connected to the lead screw 52. The lifting block 53 is connected to the lead screw 52. The lifting frame 54 is fixed on the lifting block 53. The scraping dust removal component 55 is set at one end of the lifting frame 54. When the drive motor 51 is started, it drives the lead screw 52 to rotate. The lifting block 53 connected to the lead screw 52 drives the lifting frame 54 to move up and down. The scraping dust removal component 55 at one end of the lifting frame 54 moves synchronously to clean and remove dust from the air intake filter 4.

[0032] A guide rail is fixed to the rear side of the mounting bracket 3, and a slider is fixed to one end of the lifting block 53. The lifting block 53 is slidably connected to the guide rail through the slider. The cooperation between the guide rail and the slider prevents the lifting block 53 from rotating with the lead screw 52, ​​ensuring that the lifting block 53 only moves in the vertical direction, thereby ensuring that the scraping dust removal component 55 always adheres to the surface of the air intake filter 4.

[0033] The scraping dust removal assembly 55 includes a connecting frame 551, a scraper 552, a cleaning brush 553, and a return spring 554. The scraper 552 and the cleaning brush 553 are fixed on the connecting frame 551, which is connected to the lifting frame 54 via the return spring 554. The scraper 552 is positioned above the cleaning brush 553, and both the scraper 552 and the cleaning brush 553 are in contact with the surface of the air intake filter 4. The scraper 552 scrapes away large and stubborn dust particles from the air intake filter 4, while the cleaning brush 553 performs a secondary cleaning of the fine dust particles remaining on the surface of the air intake filter 4. The scraping dust removal assembly 55 is connected to the lifting frame 54 via the return spring 554, ensuring that the scraper 552 and the cleaning brush 553 are always in close contact with the surface of the air intake filter 4, thus improving the cleaning effect.

[0034] The sliding frame 61 is slidably connected to the support base 1. The positioning frame 62 is fixed to one end of the sliding frame 61. The dust filter 63 is fixed to the positioning frame 62. The dust filter 63 is flush with the height of the fan 7. The air drawn into the support base 1 is further filtered through the dust filter 63 to remove fine dust particles, so that the dust is retained between the dust filter 63 and the sealing baffle 64. This, together with the dust collection trough 65, enables the classified collection of dust. The sealing baffle 64 is fixed in the middle position of the sliding frame 61. The dust collection trough 65 is located on one side of the sealing baffle 64 near the opening. The dust inlet 66 is located on the support base 1 above the dust collection trough 65. The dust inlet 66 is located below the front side of the air intake filter 4. The dust removed from the air intake filter 4 falls into the dust collection trough 65 through the dust inlet 66 of the support base 1. When the dust in the dust collection trough 65 accumulates to a certain amount, the dust collection filter assembly 6, which is slidably connected in the support base 1, can be completely pulled out to complete the cleaning of the dust collection trough 65 or the maintenance and replacement of the dust removal filter 63.

[0035] The inner cavity of the support base 1 is provided with protrusions 8 that match the positioning frame 62 and the sealing baffle 64. The positioning frame 62 and the sealing baffle 64 are provided with sealing gaskets on the side facing the protrusions 8. When the sliding frame 61 is inside the support base 1, the positioning frame 62 and the sealing baffle 64 fit against the protrusions 8 on the inner wall of the support base 1, restoring the sealing state of the support base 1.

[0036] The working principle and process of a construction dust collection device: The device can be flexibly moved to the dust-generating area by the casters 2 at the bottom of the support base 1. The fan 7 at one end of the support base 1 is started. The operation of the fan 7 creates a negative pressure environment inside the device. Under the action of negative pressure, the dusty air from the outside enters the device through the air intake filter 4 at the front opening of the mounting frame 3. The air intake filter 4 first intercepts large dust particles in the air. The air that has passed through the initial filtration enters the inner cavity of the support base 1 and is further filtered by the dust removal filter 63 in the dust collection filter assembly 6 to remove fine dust particles in the air, thereby collecting the dust. When there is a lot of dust on the surface of the air intake filter 4, the drive motor 51 of the filter cleaning mechanism 5 is started to drive the lead screw 52 to rotate. The lifting block 53 connected to the lead screw 52, ​​under the limiting and guiding action of the guide rail on the rear side of the mounting frame 3, drives the lifting frame 54 to move up and down reciprocally. The lifting frame 54 is activated, and the scraping dust removal component 55 at one end moves synchronously. The scraper 552 scrapes away large and stubborn dust particles from the air intake filter 4, while the cleaning brush 553 below performs a secondary cleaning of the fine dust remaining on the surface of the air intake filter 4. The scraping dust removal component 55 is connected to the lifting frame 54 through a return spring 554, which ensures that the scraper 552 and the cleaning brush 553 are always in close contact with the surface of the air intake filter 4, improving the cleaning effect. The dust removed from the air intake filter 4 falls into the dust collection tank 65 through the dust inlet 66 of the support base 1. When the dust in the dust collection tank 65 accumulates to a certain amount, the dust collection filter component 6, which is slidably connected in the support base 1, can be pulled out as a whole to complete the cleaning of the dust collection tank 65 or the maintenance and replacement of the dust removal filter 63. After the operation is completed, the sliding frame 61 is pushed back, and the positioning frame 62 and the sealing baffle 64 are in contact with the protrusion 8 on the inner wall of the support base 1 to restore the sealing state of the support base 1.
