Therefore, the fixed dust suppression device cannot be adjusted accordingly according to the specific wind direction and wind level, resulting in reduced dust suppression efficiency. At the same time, it will also cause a large area of ​​mud and water mixing on the road surface in the non-dust suppression area, greatly hindering workers' construction.

The main control unit 4 receives the electrical signals from the wind direction and wind force monitor 3, and transmits them to the electric-controlled hydraulic rod 6 and the adjustable dust reduction mechanism 7 in a wireless form, thereby controlling the extension and retraction of the electric-controlled hydraulic rod 6, and at the same time controlling the adjustable dust reduction mechanism 7 to adjust the injection position and injection direction.

[0022] In the present invention, the adjustable dust suppression mechanism 7 includes a guide block 71, a mounting frame 72, a mounting collar 73, a connecting rod 75, a threaded rod 76, a screw sleeve 771, a guide sleeve 77, a fixed guide rod 90 and a linkage assembly; one side of the guide block 71 is fixed to the output end of the electric control hydraulic rod 6, the mounting frame 72 is fixed to the guide block 71, the mounting collar 73 is symmetrically arranged with two, respectively fixed at the two ends of the mounting frame 72, the connecting rod 75 is rotatably arranged in the two mounting collars 73, the threaded rod 76 is arranged with two groups, each group is linearly arranged There are N guide rods, and each group is spliced ​​into a guide rod. Two guide rods are symmetrically fixed at both ends of the connecting rod 75. The screw sleeves 771 are also configured with two groups, each group is linearly configured with N, and are respectively threadedly connected with a corresponding threaded rod 76. The guide sleeves 77 are configured with two groups, each group is linearly configured with N, and the guide sleeves 77 are set and rotatably arranged on the screw sleeves 771. The fixed guide rods 90 are configured with two, one end of the fixed guide rods 90 is fixed on one of the mounting collars 73, and the other end of the fixed guide rods 90 slides through a group of guide sleeves 77 in sequence; The linkage assembly includes a guide rod 80, a rotating block 81, a worm 82 and a worm wheel 83; the guide rod 80 is arranged in a vertical direction and fixed on the connecting frame 5, a spiral groove is provided on the outer wall of the guide rod 80, and the cross section of the spiral groove is rectangular, an annular groove is provided in the guide block 71, the outer wall of the rotating block 81 is rotatably arranged in the annular groove, and a rectangular key 811 is fixed on the inner wall of the rotating block 81, and the rectangular key 811 is slidably arranged in the spiral groove, the worm 82 is fixed at the lower end of the rotating block 81, the guide rod 80 rotates and passes through the worm 82, the worm wheel 83 is fixed on the outer wall of the connecting rod 75, and the worm 82 is meshed with the worm wheel 83; As a preferred embodiment, the adjustable dust reduction mechanism 7 further includes an injection assembly 74, a conduit 78 and a liquid guiding hose 79; the injection assembly 74 is configured with 2N pieces, which are respectively arranged on the side of the guide sleeve 77 away from the liquid supply box 2, one end of the conduit 78 is connected to the liquid supply box 2, and the liquid guiding hose 79 is configured with 2N pieces, which are arranged between two of the injection assemblies 74, and one of the liquid guiding hoses 79 is connected to the conduit 78; It should be further explained that the pitch of each group of threaded rods 76 increases from the side close to the connecting rod 75 to the side far away from the connecting rod 75 .

[0023] The fixed guide rod 90 can keep the plurality of guide sleeves 77 level when moving.

[0024] It should be explained that, by driving the electric-controlled hydraulic rod 6, the plurality of injection assemblies 74 can be driven to move up and down, thereby adjusting the distance between the injection assemblies 74 and the ground.

[0025] That is, when the connecting rod 75 rotates to drive the multiple threaded rods 76 to rotate, the distance between two adjacent guide sleeves 77 increases or decreases, thereby driving the multiple injection assemblies 74 to expand or contract synchronously.

[0026] It should be noted that N is a positive integer greater than 1, that is, multiple spray assemblies 74 are required to cooperate in atomization and dust reduction.

[0027] It should also be noted that the liquid guiding hose 79 can adaptively extend or contract as the spacing between the multiple injection assemblies 74 changes.

[0028] During specific operation, the liquid supply box 2 transports water to the liquid guiding hose 79 through the conduit 78, and the gas in the tube is exhausted through each injection assembly 74, so that the tube is filled with water and the water pressure at each position is kept consistent, thereby atomizing and dust reduction is performed through the injection assembly 74.

[0029] For details, please refer to Figures 2 to 5 When the electric-controlled hydraulic rod 6 drives the guide block 71 to move up and down, the rotating block 81 will move synchronously with the guide block 71, wherein the rectangular key 811 will spirally rise or spirally descend along the spiral groove, thereby driving the rotating block 81 to rotate while moving up and down, thereby driving the worm 82 to rotate, and when the worm 82 is engaged with the worm wheel 83, the worm wheel 83 can drive the connecting rod 75 to rotate, thereby driving the multiple threaded rods 76 to rotate synchronously, and thereby the multiple injection assemblies 74 can expand or contract synchronously. Therefore, through the extension and retraction of the electric-controlled hydraulic rod 6, both the distance between the multiple injection assemblies 74 and the ground and the distance between the injection assemblies 74 can be adjusted.

[0030] It should be noted that if the monitored wind direction is downward or the wind force level is low, in order to avoid the droplets being blown directly to the ground and causing secondary pollution, in this case, it is necessary to adjust the distance between the injection assembly 74 and the ground to maintain a certain safe distance.

[0031] As a preferred embodiment, the injection assembly 74 includes a U-shaped block 741, a cross-shaped tube 742, a fixed nozzle 743, a three-way tube 744, a servo motor 745 and a T-shaped connecting rod 746; the U-shaped block 741 is fixed on the guide sleeve 77, the upper open end of the cross-shaped tube 742 is fixed to the top of the inner end surface of the U-shaped block 741, the left and right open ends both penetrate the U-shaped block 741 and are connected to the two liquid guide hoses 79, and the fixed nozzle 743 is arranged below the cross-shaped tube 742 The upper open end of the three-way pipe 744 is sealed and rotatably arranged in the rectangular guide groove of the cross tube 742, and the lower open end is fixed to the fixed nozzle 743. The servo motor 745 is fixedly installed on the upper end surface of the U-shaped block 741. The servo motor 745 is fixed on the U-shaped block 741, and its output end rotates through the U-shaped block 741 and is coaxially fixed with one end of the T-shaped connecting rod 746. The other two ends of the T-shaped connecting rod 746 are fixed on the inner wall of the three-way pipe 744.

[0032] See also Figure 6 to Figure 7 The spray assembly 74 is divided into fixed vertical downward spray and adjustable spray. That is to say, the fixed spray is atomized and dust-reduced through a fixed nozzle 743, which is a conventional technology and will not be elaborated here; and the adjustable spray can be adjusted accordingly according to the wind direction and wind force so that more droplets can contact the dust.

[0033] As a preferred embodiment, the injection assembly 74 also includes a connecting pipe 747, a servo motor 748, a spur gear 749, a rotating nozzle 750 and a gear ring 751; one end of the connecting pipe 747 is sealed and fixed to one of the access ends of the three-way pipe 744, and the other end is configured as an inclined end face. The servo motor 748 is fixed to the extended end of the connecting pipe 747, and the spur gear 749 is fixed on the output shaft of the servo motor 748. The input end of the rotating nozzle 750 is also configured as an inclined end face, and is sealed and rotatably arranged in the connecting pipe 747. The gear ring 751 is fixed on the outer wall of the input end of the rotating nozzle 750 and meshes with the spur gear 749.

[0034] Specifically, in the above, a connecting disk 1 is fixed on the outer wall of the inclined end face of the connecting tube 747, and a connecting disk 2 is fixed on the outer wall of the access end of the rotating nozzle 750. The outer walls of the connecting disk 1 and the connecting disk 2 are both configured to be circular, and a T-shaped ring groove is opened in the connecting disk 1, and a T-shaped ring block is connected to the connecting disk 2 near one end of the connecting tube 747. The T-shaped ring block rotates in the T-shaped ring groove in a sealed manner, and the gear ring 751 is fixed on the outer wall of the connecting disk 2. That is to say, under the drive of the servo motor 2 748, the spur gear 749 and the gear ring 751 always maintain a meshing state in the inclined direction, and when the connecting disk 1 rotates relative to the connecting disk 2, the contact surfaces of the two always remain in contact, that is, the two will not be misaligned, thereby avoiding liquid leakage.

[0035] As a preferred embodiment, the angle between the inclined end surface of the connecting pipe 747 and the horizontal plane is 45°, and the port faces downward.

[0036] Among them, see Figure 8 The servo motor 2 748 drives the spur gear 749 to rotate, thereby driving the gear ring 751 to rotate, so that the spray direction of the rotary nozzle 750 has an angle of 0°~90° with the horizontal. That is to say, under the drive of the servo motor 1 745, the spray direction of the rotary nozzle 750 can be adjusted in the circumferential direction, and under the drive of the servo motor 2 748, the spray direction of the rotary nozzle 750 can be adjusted in the vertical direction.

[0037] As a preferred embodiment, the servo motor 1 745 and the servo motor 2 748 are both electrically connected to the main control unit 4 .

[0038] Specifically in the first embodiment, if the wind direction measured by the wind direction and wind force monitor 3 is downward wind, the main control unit 4 controls the electric control hydraulic rod 6 to contract, so that the multiple nozzles move up and close together, and at the same time controls the servo motor 2 748 to drive the spray direction of the rotating nozzle 750 vertically downward, and controls the servo motor 1 745 to continuously drive the rotating nozzle 750 to rotate circumferentially, thereby forming an annular spray area. Therefore, in the above state, the spray effects of the rotating nozzle 750 and the fixed nozzle 743 are superimposed, increasing the effective contact area between the droplets and the dust, thereby improving the dust reduction efficiency; Specifically in the second embodiment, if the wind direction measured by the wind direction and wind force monitor 3 is a side wind or an oblique upward wind, the main control unit 4 controls the electric-controlled hydraulic rod 6 to extend, so that the multiple nozzles move downward and expand, and at the same time controls the servo motor 1 745 and the servo motor 2 748 to start, so that the spray direction of the rotating nozzle 750 is directly opposite to the wind direction. Therefore, the droplets can form a counter-attack with the wind, which can slow down the wind force and avoid a large number of droplets being blown away by the wind, so that more droplets can come into contact with dust, thereby further improving the dust reduction efficiency.

[0039] Specifically, see Fig. 9 If the wind level monitored by the wind direction and wind force monitor 3 is the same and the angle α between the wind direction and the ground decreases, the main control unit 4 controls the electric control hydraulic rod 6 to extend, and the distance between each fixed nozzle 743 and each rotating nozzle 750 and the ground is shortened while the distance between the nozzles is increased, so that the effective area of ​​the sprayed droplets is increased, and the dust at the edge of the dust to be removed can be removed; Also, see Fig.10, if the wind direction monitored by the wind direction and wind force monitor 3 is the same, when the wind force increases from F1 to F2, similarly, the main control unit 4 controls the electric control hydraulic rod 6 to extend, so that the distance between each fixed nozzle 743 and each rotating nozzle 750 and the ground is shortened and the distance between the nozzles is increased, thereby reducing the time that dust stays in the air, avoiding rapid diffusion of dust, and allowing the sprayed droplets to act on the dust at the edge of the dust to be removed; Therefore, in the above two cases, the area covered by the droplets sprayed by each nozzle can just match the required dust reduction area. That is to say, under the premise of complete dust reduction, secondary pollution of areas outside the dust reduction area by droplets can be avoided, and the waste of water resources can be avoided.

[0040] As a preferred embodiment, the liquid supply box 2 is also provided with a power pump 21 for providing power to the adjustable dust suppression mechanism 7 .

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
