[0023] One of the preferred embodiments of this application is as follows: Figures 1 to 6As shown, a dust removal device for construction sites includes a working box 1, and support bases 13 are fixedly installed on the outer walls of the four corners of the bottom of the working box 1.

It also includes: a mounting shell 2, a collection box 3, a rotating motor 4, a rotating base 14, a filter screen 6, a threaded rod 5, a sliding sleeve 7, an arc-shaped scraping mechanism and a limiting mechanism. The mounting shell 2 is fixedly installed on one side of the working box 1, and circular openings that are interconnected are provided between the mounting shell 2 and the working box 1. An air inlet pipe 9 is fixedly installed on the outer wall of the top of one side of the mounting shell 2, and an air outlet pipe 10 is fixedly installed on the top of the other side of the working box 1; a sliding opening is provided at the bottom of one end of the mounting shell 2, and the collection box 3 is inserted into the sliding opening; the rotating motor 4 is fixed Installed on the middle outer wall of the other side of the working box 1; one side of the rotating base 14 is fixedly mounted on the output shaft of the rotating motor 4; the filter screen cover 6: the filter screen cover 6 is cylindrical, and one end of the filter screen cover 6 is fixedly mounted on the circumference of the other side of the rotating base 14, and the other end of the filter screen cover 6 is rotatably mounted on the inner wall of the circular opening; one end of the threaded rod 5 is fixedly mounted on the center position of the other side of the rotating base 14, and the other end of the threaded rod 5 passes through the circular opening and is rotatably mounted on one side of the inner wall of the mounting shell 2; the inner wall of the sliding sleeve 7 is connected to the threaded rod 5 by a thread; the arc-shaped scraping mechanism is installed on the outer wall of the bottom of the sliding sleeve 7; there are two groups of limiting mechanisms, and the two groups of limiting mechanisms are respectively arranged at the top two ends of the arc-shaped scraping mechanism, so as to make the arc-shaped scraping mechanism move horizontally.

[0024] After the filter screen 6 is filtered, the filter screen 6 is blown away by the filter element 10, and the filter screen 6 is turned off.

[0025] For further reference, Figure 3-Figure 5The arc-shaped scraping mechanism includes: two connecting plates 801, a support plate 802 and two scrapers 803. The top ends of the support plate 802 are fixedly connected to the bottom outer wall of the sliding sleeve 7 through the connecting plates 801. The sides of the tops of the two scrapers 803 close to each other are hinged to the two sides of the bottom of the support plate 802 respectively; the bottom curved surfaces of the two scrapers 803 are arranged to fit the inner wall of the filter screen cover 6, and a cavity is formed between the two scrapers 803 and the inner wall of the filter screen cover 6; the first state: when the two scrapers 803 are stationary, the two scrapers 803 are both in the vertical position. Straight state; second state: when the arc-shaped scraping mechanism moves to the right, the bottom of the scraper 803 on the right is tilted and approaches the other scraper 803, and the other scraper 803 is in a vertical limited state, and the dust enters the cavity between the two scrapers 803 from the bottom of the tilted scraper 803; when the arc-shaped scraping mechanism moves to the left, the bottom of the scraper 803 on the left is tilted and approaches the other scraper 803, and the other scraper 803 is in a vertical limited state, and the dust enters the cavity between the two scrapers 803 from the bottom of the tilted scraper 803.

[0026] When the arc-shaped scraping mechanism is in operation, in the initial state, the two scraping plates 803 are in a vertical state. When the device is started, the arc-shaped scraping mechanism is driven to operate as the sliding sleeve 1 7 moves. When the arc-shaped scraping mechanism moves to the right, the bottom of the scraper 803 on the right is inclined toward the other scraper 803, and the other scraper 803 is in a vertical limited state. The dust enters the cavity of the two scrapers 803 from the bottom of the inclined scraper 803. When the arc-shaped scraping mechanism moves to the left, the bottom of the scraper 803 on the left is inclined toward the other scraper 803, and the other scraper 803 is in a vertical limited state. The dust enters the cavity between the two scrapers 803 from the bottom of the inclined scraper 803. After the arc-shaped scraping mechanism moves to the left and pours the dust in the cavity into the collection box 3, the motor 4 is reversed to move the arc-shaped scraping mechanism to the right, and so on and so forth, thereby achieving comprehensive scraping of the dust on the filter cover 6 and effectively preventing the filter from being blocked.

[0027] For further reference, Figure 6 A dust removal device for a construction site, one side of the air inlet pipe 9 is trumpet-shaped, and a guide fan blade 901 is fixedly installed on the inner wall of the air inlet pipe 9.

[0028] When the device is running, air enters from the trumpet-shaped end of the air inlet pipe 9, and the guide blades 901 guide the incoming air so that the air can enter the working box 1 more smoothly for subsequent filtration through the filter cover 6. At the same time, the guide blades 901 help guide the direction of air flow, so that the air flows evenly into the filter cover 6 to achieve sufficient filtration of the air.

[0029] For further reference, Figures 1-4A dust removal device for a construction site, wherein an induced draft fan 1001 is fixedly installed on the inner circumference of the air outlet pipe 10.

[0030] During the operation of the device, after the device filters the dust-laden air, the induced draft fan 1001 is started, and the induced draft fan 1001 generates suction. Under the action of the suction, the filtered clean air is discharged through the air outlet pipe 10. The induced draft fan 1001 ensures that the air can pass through the filter cover 6 smoothly, thereby improving the dust removal efficiency.

[0031] For further reference, Figure 3-Figure 5 The limiting mechanism includes: a limiting rod 11, a sliding sleeve 12 and a limiting plate 16. One end of the limiting rod 11 passes through the circular opening and is fixedly installed on the inner wall of one side of the mounting shell 2. The sliding sleeve 12 is slidably set on the limiting rod 11. The sliding sleeve 12 is fixedly connected to one end of the top of the support plate 802. The limiting plate 16 is fixedly installed on the other end of the limiting rod 11.

[0032] One end of the limiting rod 11 is fixedly connected to the inner wall of one side of the mounting shell 2, playing a supporting and guiding role. When the arc-shaped scraping mechanism moves along with the sliding sleeve 1 7, the support plate 802 drives the sliding sleeve 2 12 to slide on the limiting rod 11, ensuring that the horizontal movement of the arc-shaped scraping mechanism is stable. The limiting plate 16 is fixedly installed at the other end of the limiting rod 11 to prevent the sliding sleeve 2 12 from sliding out of the limiting rod 11.

[0033] Working principle: First, move the device to the construction site and connect the exhaust fan to the pipe mouth of the air inlet pipe 9. The dust-laden air enters the filter cover 6 through the air inlet pipe 9. At the same time, the guide fan blades 901 guide the incoming air so that the air flows evenly into the filter cover 6 for subsequent dust filtering. Next, start the rotating motor 4. The output shaft of the rotating motor 4 drives the rotating base 14 to rotate, thereby causing the threaded rod 5 and the filter cover 6 to rotate synchronously. As the threaded rod 5 rotates, the sliding sleeve 7 sleeved thereon begins to move, thereby driving the arc-shaped scraping mechanism on the bottom outer wall to operate. In the initial state, the two scrapers 803 are in a vertical state. When the arc-shaped scraping mechanism moves to the right, the bottom of the scraper 803 on the right tilts toward the other scraper 803, and the other scraper 803 is in a vertical limited state. Dust enters the cavity of the two scrapers 803 from the bottom of the inclined scraper 803. When the arc-shaped scraping mechanism moves to the left, the scraper 803 on the left The bottom is tilted toward the other scraper 803, and the other scraper 803 is in a vertical limited state. The dust enters the cavity between the two scrapers 803 from the bottom of the inclined scraper 803. When the arc-shaped scraping mechanism moves to the left to pour the dust in the cavity into the collection box 3, the motor 4 is reversed to move the arc-shaped scraping mechanism to the right, and this is repeated to achieve comprehensive scraping of the dust on the filter cover 6, effectively preventing the filter from being blocked. In this process, one end of the limit rod 11 is fixedly connected to the inner wall of one side of the mounting shell 2 to play a supporting and guiding role. The support plate 802 drives the sliding sleeve 2 12 to slide on the limit rod 11 to ensure stable horizontal movement of the arc-shaped scraping mechanism. The limit plate 16 is fixedly installed at the other end of the limit rod 11 to prevent the sliding sleeve 2 12 from sliding out, and finally the filtered clean air is discharged from the working box 1 through the air outlet pipe 10 through the induced draft fan 1001, thereby ensuring a good dust removal effect.

The above-described embodiments and the specification merely illustrate the principles of the present application.
