Dust collection mechanism

The invention discloses a dust collection mechanism, and relates to the technical field of airport dust collection, according to the dust collection mechanism, through a cleaning assembly, when the outer surface of a tough cleaning plate makes contact with the airport ground, a sliding plate located in a cylindrical rod is affected by counter-acting force after the outer surface of the tough cleaning plate is subjected to the gravity of a dust collection box, and a square plate and an arc-shaped push plate can be driven to move towards the inner side together; when a square plate moves, a spring is extruded, when an arc-shaped push plate moves, water in a water storage tank is extruded, when a sliding plate returns to the original position under the influence of the spring, the water in the water storage tank enters a water guide groove under the influence of the negative pressure effect, and then flows out of a water outlet through a water limiting plate; according to the airport ground cleaning device, the
