[0045] When the rotary dust collection mechanism is used, the motor 7 is controlled to drive the active bevel gear 8 to rotate, and then the driven bevel gear 9 meshing with the active bevel gear 8 drives the dust collection pipe 5 to rotate, and then the dust collection pipe 5 drives the dust collection hood 6 to rotate to achieve the effect of all-round and multi-angle dust collection by the dust collection hood 6;

[0046] Specifically, the height-adjustable dust filtering mechanism includes a mounting frame 10 adapted to the dust removal box 2, a main filter element 11 and a spare filter element 12 fixedly inserted into the mounting frame 10 from top to bottom, a stepper motor 13 fixedly mounted on the rear inner wall of the dust removal box 2, two bearing seats 14 symmetrically fixed to the rear inner wall of the dust removal box 2, and a vertical lead screw 15 rotatably mounted on the two bearing seats 14 and threadedly connected to the mounting frame 10. By sequentially arranging the main filter element 11 and the spare filter element 12 in the mounting frame 10, the dust removal and purification process mainly relies on the main filter element 11 above. In an emergency situation where the main filter element 11 needs to be replaced and is out of stock, the spare filter element 12 can be used to replace it for a period of time to ensure the normal use of the entire dust removal equipment.

[0050] In this embodiment, the air guide mechanism includes a plurality of equally spaced rotating air guide components and a synchronous drive component. Specifically, the purpose of the air guide mechanism is to allow dust to evenly cover the surface of the main filter element 11; further, when the dust evenly covers the surface of the filter element, all parts of the filter element can participate in the filtering process, avoiding the decrease in filtering efficiency caused by local excessive blockage, and ensuring that air can evenly pass through the filter element, thereby improving the overall filtering effect; further, if the dust is only concentrated in a certain area of ​​the filter element, then this area may cause damage to the filter element due to excessive dust accumulation, thereby affecting the service life of the filter element, and uniform dust coverage can enable all parts of the filter element to withstand a certain dust load, thereby extending the service life of the filter element;

[0051] Specifically, the rotary air guide assembly includes a shaft 17 rotatably mounted in the air equalizing cover 34, an air guide strip 18 fixedly connected to the shaft 17, and a worm gear 19 fixedly sleeved on one end of the shaft 17;

[0052] Furthermore, the synchronous drive assembly includes a fixed cover 20 fixedly connected to the outer wall of the rear side of the gas equalizing cover 34, a drive motor 21 fixedly installed on the side wall of the fixed cover 20, a transmission shaft 22 rotatably installed in the fixed cover 20, and a worm 23 fixedly sleeved on the transmission shaft 22 and having the same number as the worm gear 19, each worm 23 is meshed with each corresponding worm gear 19 in turn, and the output end of the drive motor 21 is coaxially fixedly connected to one end of the transmission shaft 22;

[0053] During the specific implementation of this embodiment: when the dust-containing gas is sucked into the gas equalizing hood 34 by the dust suction pipe 5, the driving motor 21 is used to control the rotation of each worm 23 on the transmission shaft 22, and then each worm wheel 19 meshing with each worm 23 will drive the air guide strips 18 on each shaft body 17 to rotate continuously. In this way, the air inlet angle is continuously changed by the continuous rotation of multiple air guide strips 18 in the same direction, so that the dust-containing gas can be evenly guided to the surface of the main filter element 11, so that the dust on the surface of the main filter element 11 is evenly covered, so that the filter material on the surface of the main filter element 11 can be evenly and fully utilized, which is beneficial to improving the filtration efficiency of the main filter element 11 and extending its service life.

[0054] Example 3, reference Figure 1 and Fig.11 , This embodiment is optimized on the basis of embodiment 1, specifically: an indoor high-efficiency air dust removal device for construction engineering, further comprising a reciprocating mechanism;

[0055] Specifically, the reciprocating mechanism includes a servo drive assembly, a slide slot 24 provided on the top of the base 1, a transverse lead screw 25 rotatably installed in the slide slot 24, a sliding seat 26 threadedly connected to the transverse lead screw 25, and two transverse guide rails 27 symmetrically fixed to the outer wall of the top of the base 1;

[0056] More specifically, the servo drive assembly includes a protective cover 28 fixedly connected to the front outer wall of the base 1, a servo motor 29 fixedly mounted on the front outer wall of the protective cover 28, a driving pulley 30 fixedly mounted on the output shaft of the servo motor 29, and a driven pulley 31 fixedly mounted on one end of the transverse lead screw 25;

[0057] Furthermore, the sliding seat 26 is also slidably connected between the two transverse guide rails 27, and the top outer wall of the sliding seat 26 is fixedly connected to the bottom outer wall of the dust removal box 2;

[0058] Furthermore, the output shaft of the servo motor 29 passes through the front side of the protective cover 28, the driving pulley 30 and the driven pulley 31 are both located in the protective cover 28, and the driving pulley 30 and the driven pulley 31 are connected by the same transmission belt 32;

[0059] During the specific implementation of this embodiment: the active pulley 30 is driven to rotate by the servo motor 29, and then under the transmission effect of the transmission belt 32, the driven pulley 31 will drive the transverse screw 25 to rotate, and under the guidance of the two transverse guide rails 27, the sliding seat 26 threadedly connected to the transverse screw 25 will drive the entire dust removal box 2 to reciprocate in the horizontal direction, which can effectively expand the dust removal area of ​​the entire air dust removal equipment and improve the dust removal efficiency of indoor air.

[0060] The use process of the present invention is as follows: first, the four dust suction fans 3 are started to generate suction force at the dust hood 6, and then the active bevel gear 8 is driven to rotate by the control motor 7, and then the driven bevel gear 9 meshing with the active bevel gear 8 drives the dust suction pipe 5 to rotate, and then the dust suction pipe 5 drives the dust hood 6 to rotate to achieve the effect of all-round and multi-angle dust suction of the dust hood 6, thereby improving the dust removal effect;

[0061] Secondly, the driving pulley 30 is driven to rotate by the servo motor 29, and then the driven pulley 31 drives the transverse screw 25 to rotate under the transmission effect of the transmission belt 32. Under the guidance of the two transverse guide rails 27, the sliding seat 26 threadedly connected to the transverse screw 25 drives the entire dust removal box 2 to reciprocate in the horizontal direction, which can effectively expand the dust removal area of ​​the entire air dust removal equipment and improve the dust removal efficiency of indoor air;

[0062] Finally, when the dust-laden gas is sucked into the gas equalizing hood 34 by the dust suction pipe 5, the driving motor 21 is used to control the rotation of each worm gear 23 on the transmission shaft 22, and then each worm wheel 19 meshing with each worm gear 23 will drive the air guide strips 18 on each shaft body 17 to rotate continuously. In this way, the air inlet angle is continuously changed by the continuous rotation of multiple air guide strips 18 in the same direction, so that the dust-laden gas can be evenly guided to the surface of the main filter element 11, so that the dust on the surface of the main filter element 11 is evenly covered, so that the filter material on the surface of the main filter element 11 can be evenly and fully utilized, which is beneficial to improving the filtration efficiency of the main filter element 11 and extending its service life.
