The linkage assembly includes a rotating plate 12 hinged on the top of the moving block 11, a lifting plate 13 is arranged on the top of the rotating plate 12, a sliding block 14 is hinged on the top of the rotating plate 12, a sliding groove 15 is provided at the bottom of the lifting plate 13, the sliding block 14 slides in the inner cavity of the sliding groove 15, a telescopic rod 16 is installed between the bottom of the inner cavity of the protective box 4 and the bottom of the lifting plate 13, four groups of telescopic rods 16 are arranged and distributed in a rectangular array, and a working assembly is installed on the top of the lifting plate 13. The limiting assembly includes a limiting rod 17 installed in the inner cavity of the protective box 4, the limiting rod 17 is inserted in the inner cavity of the moving block 11, and multiple groups of limiting rods 17 are arranged and distributed horizontally symmetrically.

[0032] The working principle of the embodiment of the present invention is: the overall movement and positioning of the equipment is achieved through the transport vehicle body 1, and the telescopic function of the roller 2 is controlled by the telescopic mechanism to ensure the stability and mobility of the equipment under different ground conditions.

[0033] When the equipment reaches the designated construction area, the storage mechanism starts, and the dual-axis motor 5 in the driving assembly serves as the core power source. Its output shaft drives the first bidirectional screw 6 and the second bidirectional screw 7 to rotate respectively. Through the belt 10 transmission, the first rotating rod 8 and the second rotating rod 9 realize synchronous rotation to ensure the movement consistency of the bidirectional screw. The rotation of the bidirectional screw drives the moving block 11 to move horizontally along the screw axis. The linkage assembly at the top of the moving block 11 converts the horizontal movement into lifting movement. The rotating plate 12 cooperates with the sliding block 14, and through the guiding effect of the sliding groove 15, the lifting plate 13 is pushed up or down vertically.

[0034] The working component on the top of the lifting plate 13 further adjusts the posture of the dust reduction device 3. Through the support of the telescopic rod 16, the vertical movement of the lifting plate 13 is more stable. After the dust reduction device 3 finally reaches a predetermined height, it starts to perform dust reduction operations and sprays water mist to the construction area through its internal spray system to achieve a dust reduction effect. When the dust reduction device 3 is not in use, the dual-axis motor 5 is started to drive the dust reduction device 3 to descend to the inside of the protective box 4, and through the cooperation of the sealing cover plate, the dust reduction device 3 inside the protective box 4 is protected to avoid being damaged by collision with building materials when the equipment is placed aside.

When the equipment is performing dust reduction, in order to improve the stability of the device, the variable motor 19 is started to drive the roller 2 to retract to the inside of the transport vehicle body 1, thereby avoiding the movement of the equipment during dust reduction.

[0038] The rotating motor 26 in the working component drives the rotating rod 27 to rotate, driving the driving gear 28 to mesh with the driven gear 30.

Through the synergistic effect of the telescopic mechanism and the working component, the equipment can flexibly adjust the support height of the roller 2 and the spray direction of the dust suppression device 3 according to the terrain and dust distribution of the construction site, so as to achieve efficient dust suppression operation.

An adjustable guide blade is provided at the outlet end of the guide cover. The opening and closing angle of the guide blade is linked to an external wind speed sensor for dynamically correcting the water mist diffusion trajectory.

[0041] The working principle of the embodiment of the present invention is as follows: in the equipment positioning and ground adaptation stage step S1, the transport vehicle body 1 moves to the construction area, the telescopic mechanism is started, the variable motor 19 drives the third bidirectional screw 20 to rotate, and adjusts the support height of the roller 2 to adapt to the ground slope and load requirements, ensuring the stability of the equipment. In the lifting and adjustment stage step S2, the dual-axis motor 5 synchronously drives the first bidirectional screw 6 and the second bidirectional screw 7 to rotate, the moving block 11 moves horizontally along the limit rod 17, and the linkage component converts the horizontal movement into the vertical lifting of the lifting plate 13. Through the synchronous extension and retraction of the telescopic rod 16, the stability of the lifting process is ensured, so that the dust removal device 3 reaches the target working height. In the three-dimensional angle calibration stage step S3, the rotating motor 26 drives the active gear 28 to mesh with the driven gear 30 to control the horizontal rotation angle of the dust removal device 3, and the electric push rod 31 in the tilting assembly adjusts the pitch angle of the lifting block 32 to achieve precise alignment of the dust removal device 3 in three-dimensional space, ensuring that the spray direction can cover the dust area.

[0042] In the dynamic dust suppression operation stage, step S4, the dust suppression device 3 switches different spray modes according to the distribution characteristics of construction dust, such as directional spray, fan-shaped coverage or intermittent pulse mode. The adjustable guide blades of the guide cover are linked with the external wind speed sensor to dynamically correct the water mist diffusion trajectory to further improve the dust suppression effect. At the same time, the synchronous extension and retraction of the telescopic rod 16 compensates for the force deviation of the lifting plate 13 to ensure the stability of the equipment during operation. In the recovery and storage stage, step S5, after the operation is completed, the dust suppression device 3 is lowered to the top of the transport vehicle 1 and locked through the storage mechanism, and the telescopic mechanism retracts the roller 2 to the inner cavity of the transport vehicle 1 to complete the recovery and storage of the equipment, which is convenient for subsequent movement and storage.
