DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Large-scale land leveling operations will disturb the surface soil layer, exposing a large amount of soil and dust to the air, especially in dry weather conditions, mechanical operations and vehicle driving will raise a lot of dust. When loading and unloading sand, gravel, cement, fly ash and other materials at the construction site, due to the large height difference, the collision and friction between the materials will cause dust to be raised. When removing old road surfaces, such as breaking concrete roads and shoveling asphalt roads, a large amount of dust and gravel will be generated. Therefore, during road construction, different construction conditions will produce dust effects, and the sites and environments for dust generation are different. Therefore, a dust suppression device that can be applied to multiple environments is needed.

[0023] like Figure 1 and Figure 2 As shown, the present invention provides a technical solution: a dust suppression device for road construction based on urban construction, comprising a vertical frame 1, a net assembly 2, a plurality of double-way joints 3, a dust suppression spraying device 8, a synchronous driving member 9 and an air supply assembly; A plurality of dust reduction spray devices 8 are provided and installed in the vertical frame 1, the mesh assembly 2 is installed on one side of the vertical frame 1, and the spraying direction of the dust reduction spray device 8 is toward the side of the mesh assembly 2. Water is sprayed on the mesh assembly 2 through the dust reduction spray device 8 to expand the atomization range and improve the dust reduction effect. The dust reduction spray device 8 can adjust the spraying direction. When the dust reduction spray device 8 sprays toward the high altitude, the mesh assembly 2 is opened, which will block the sprayed water and increase the spraying height. The air supply assembly is arranged on the side away from the mesh assembly 2 to increase the atomization range. The mesh assembly 2 is connected to the dust reduction spray device 8 through a synchronous drive member 9, and the mesh assembly 2 is controlled by adjusting the spraying angle of the dust reduction spray device 8.

[0024] The vertical frame 1 includes two upper and lower cross beams 101, and the two ends of the two cross beams 101 are connected by side bars 102 to form a rectangular frame. Base feet 103 are installed at both ends of the bottom of the bottom cross beam 101 to improve the stability of the dust reduction device. The top of the cross beam 101 at the bottom and the bottom of the cross beam 101 at the top are both provided with slots with two ends passing through, wherein the mesh assembly 2 includes a rectangular frame 201, the top and bottom of the rectangular frame 201 are adapted to the slots and can be inserted into the slots to facilitate the installation of the mesh assembly 2, and the hollow area of ​​the rectangular frame 201 of the mesh assembly 2 overlaps with the hollow area of ​​the vertical frame 1.

[0025] like Figure 1 As shown, the mesh assembly 2 also includes a plurality of connecting rods 202 rotatably installed between the two sides of the rectangular frame 201. The connecting rods 202 are arranged in parallel, and fine meshes 203 are fixed on the surface of the connecting rods 202. The width of the fine mesh 203 is slightly smaller than the gap between every two connecting rods 202 to ensure that the fine mesh 203 can rotate smoothly when the connecting rods 202 rotate.

[0026] like Figure 3 As shown, a plurality of dust suppression spraying devices 8 are provided and are equidistantly installed between the side bars 102 on both sides of the vertical frame 1. Each dust suppression spraying device 8 includes a vertical pipe 801. Sealing gaskets 802 are relatively installed at the bottom of the top crossbar 101 and the top of the bottom crossbar 101. The vertical pipe 801 is installed at the corresponding sealing gaskets 802 above and below. The sealing gasket 802 is provided to ensure the sealing effect of the connection between the vertical pipe 801 and the vertical frame 1, and also ensure the stability of the vertical pipe 801. A row of bypass holes are provided on both sides of each vertical tube 801, and a sealed bearing 803 is installed on the inner wall of each bypass hole. A high-pressure atomizing nozzle 806 is fixed on the inner wall of the sealed bearing 803, and the high-pressure atomizing nozzle 806 sprays toward one side of the mesh assembly 2. A synchronization rod 807 is provided through the top of the vertical tube 801, and one end of the synchronization rod 807 is rotatably installed on one side of the side bar 102 and is also connected to each vertical tube 801 by a sealed bearing 803. One side of each high-pressure atomizing nozzle 806 is connected through a branch pipe 808. It is connected to the sealed bearing 803, and several sprockets 804 are fixed on the surface of the synchronization rod 807, and a sprocket 804 is also fixed on the branch pipe 808 of the high-pressure atomizing nozzle 806. The sprocket 804 on the synchronization rod 807 corresponds to the position of the sprocket 804 on each column of high-pressure atomizing nozzles 806, and each column of sprockets 804 is connected by a chain 805. Under the setting of this structure, when the synchronization rod 807 rotates, the angle of the high-pressure atomizing nozzle 806 on each group of dust reduction spraying devices 8 can be adjusted to adapt to various dust reduction environments.

[0027] Replay Figure 2 In addition, a switch 809 is provided at the bottom of each vertical pipe 801, and the switch 809 can control the water flow in the vertical pipe 801. It should be noted that the switch 809 is at least arranged above the bottom high-pressure atomizing nozzle 806, that is, even if the switch 809 is turned off, the bottom high-pressure atomizing nozzle 806 can still realize the spraying action after the water is passed, so that the effect of low-altitude spray dust reduction can be achieved. For the case where the dust is weak, the dust reduction effect can be achieved while saving water resources.

[0028] like Figure 3 and Figure 4 As shown, in the above structure, the synchronization rod 807 of the dust suppression spraying device 8 and one end of the connecting rod 202 of the mesh assembly 2 respectively penetrate the side bar 102 and the rectangular frame 201, and the synchronous driving member 9 includes two connecting plugs 905 respectively fixed to the ends of the synchronization rod 807 and the connecting rod 202. The cross-sectional shape of the connecting plug 905 is non-circular, and the surfaces of the two connecting plugs 905 are sleeved with gears 901, and the gears 901 are connected by a toothed belt 902. A fixing bolt 903 is screwed at the ends of the two connecting plugs 905 for In order to limit the gear 901, a driving source 7 is installed on one side of one of the side bars 102, and the output end of the driving source 7 is coaxially fixed with the synchronization rod 807 for driving. Through the setting of this structure, the synchronization rod 807 and the connecting rod 202 can rotate synchronously. That is to say, when the high-pressure atomizing nozzle 806 is adjusted in angle for high-altitude spraying by driving the synchronization rod 807, the connecting rod 202 rotates synchronously, that is to say, the fine-mesh mesh 203 will rotate synchronously driven by the connecting rod 202, open the mesh assembly 2, and increase the spraying distance.

[0029] like Figure 2 and Figure 3 As shown, a plurality of positioning pins 104 are fixed on the side of the vertical frame 1 away from the mesh assembly 2, and the air supply assembly includes a plate frame 5, on which through holes are provided and correspond to the positions of the positioning pins 104, and are fixed by nuts, and a frame 6 is installed on the side of the plate frame 5 away from the mesh assembly 2, and a fan 10 is provided in the frame 6. Through the setting of the fan 10, the dust reduction spraying device 8 can increase the dust reduction coverage range and improve the dust reduction quality with the assistance of the fan 10 when spraying horizontally.

[0030] A plurality of two-way joints 3 are respectively arranged on both sides of the two ends of the crossbar 101 at the bottom of the vertical frame 1. The two-way joints 3 can be connected to two water pipes and are connected to the vertical pipe 801 of each dust reduction spraying device 8 after passing through the inside of the crossbar 101 at the bottom. A booster pump assembly 4 is installed at the bottom of the crossbar 101 corresponding to each dust reduction spraying device 8. The booster pump assembly 4 is a booster pump device that can increase the spray pressure of the nozzle. It is an existing product and is not described here. The two-way joint 3 can be connected to two water pipes, and a valve is arranged on the two-way joint 3, which is used to control the closure of the two passages on the two-way joint 3 respectively. That is to say, any one of the passages on the two-way joint 3 can be used to connect the water pipe, and the other passage is in a closed state to ensure the water supply. In this case, the dust reduction device can be applicable to a variety of working environments.

[0031] like Figure 5 As shown, the dust reduction device of this embodiment can be a dust reduction device, which is used to increase the coverage width of the dust reduction area. Each dust reduction device is connected by a hose, and the other passage of the two-way joint 3 is closed to achieve water communication between the dust reduction devices. It is suitable for environments such as road construction that require dust reduction without occupying the site.

[0032] like Figure 6 As shown, the dust reduction device of this embodiment can be arranged at intervals to improve the dust reduction effect in the interval area. It can be used in conjunction with the fan 10 to increase the length of the interval area, and is suitable for environments such as regional construction.

[0033] like Figure 7 As shown, the dust reduction device of this embodiment can be arranged in a surrounding distribution, which is suitable for unloading soil and sand during road construction, achieving all-round coverage of the unloading area and improving the dust reduction effect.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is limited by the attached embodiments and their equivalents.
