[0057] The working principle of this embodiment is as follows: when the dust cleaning equipment for construction is used, the double-end motor 4 drives the left-end fan blade 5 to rotate when rotating, and sucks in dusty air through the air inlet slot 706, and senses the concentration through the sensor 705 to adjust the rotation speed of the double-end motor 4, and the dusty air is discharged through the notch of the end cover 703, and the fourth rotating shaft 707 is driven to rotate by the rotation of the double-end motor 4, driving the triangular support frame 708 and the first cleaning block 709 to clean the surface of the shell 2. If there is any residue, the end cover 703 is rotated to loosen it, and the left end sinks to make it slide out of the shell 2, or the angle of the shell 2 is adjusted to make it pass through the air inlet slot located below. 706 enters the collecting groove 702 and then enters the waste box 701. For cleaning the front section of the shell 2, the electromagnet 712 is used to start pushing the triangular block 713 to engage with the right end slot of the double-end motor 4, driving the rotation of the lead screw 711, and the lead screw 711 drives the movement of the slider 714. At this time, the hydraulic pump 715 pushes outward, driving the fifth rotating shaft 716 to push the second rotating shaft block 718 and the second cleaning block 719 outward to contact the inner wall of the shell 2 and clean it. Because the front end of the shell 2 is an inclined surface, the hydraulic pump 715 pushes and balances with the second spring 717 to achieve a close fit, and cooperates with the remaining cleaning components 7001 to achieve cleaning of the front end.
