[0031] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0032] Reference Figure 1-Figure 7 A spraying dust suppression device for highway engineering construction includes a mobile vehicle 100. The mobile vehicle 100 adopts the existing technology and can be controlled by the staff to move, thereby moving with the device, which will not be described in detail.

[0033] The mobile vehicle 100 is provided with a spraying dust reduction mechanism for spraying and reducing dust in the air, and the spraying range is adjustable, including the spraying direction, the spraying area and the spraying height.

[0034] The spraying and dust reduction mechanism includes a telescopic member 101 and a spraying member 102 arranged at the upper end of the telescopic member 101, a water pump 103 and a water tank arranged on the mobile vehicle 100. The water tank contains water, and the water pump 103 is used to pull the water in the water tank to flow toward the telescopic member 101 or the spraying member 102. When flowing into the telescopic member 101, the telescopic member 101 can be stretched, thereby increasing the height of the spraying member 102. When flowing toward the spraying member 102, it is spraying and dust reduction. At the same time, the spraying member 102 can rotate around the telescopic member 101 and can change the pitch angle, thereby adjusting the spraying range.

[0035] Reference Figure 2-5 The telescopic member 101 includes a rotating seat 1011 which is vertically arranged and rotatably mounted on the moving trolley 100. The rotating seat 1011 is connected to a motor 105 arranged on the moving trolley 100 through a power transmission member 106. In a preferred embodiment, the transmission ratio of the power transmission member 106 is greater than one, which is a reduction transmission.

[0036] The telescopic member 101 also includes a telescopic joint, and a plurality of telescopic joints are arranged in an array along the vertical direction. The telescopic joints are in the shape of a cylinder arranged vertically and open at both ends. The upper open end of the telescopic joint is provided with a built-in step, and the lower open end of the telescopic joint is provided with an external step. Among the two adjacent telescopic joints, the external step of the upper telescopic joint is sleeved in the lower telescopic joint, and the upper telescopic joint is prevented from detaching from the lower telescopic joint by the cooperation of the external step of the upper telescopic joint and the built-in step of the lower telescopic joint. In addition, air holes are provided on the built-in steps for gas flow when the telescopic joint moves, so as to avoid interference with the movement of the telescopic joint.

[0037] There are three types of telescopic joints, namely a bottom telescopic joint 1012, a top telescopic joint 1016 and a middle telescopic joint 1015 located therebetween, wherein one bottom telescopic joint 1012 and one top telescopic joint 1016 are each provided with one, the bottom telescopic joint 1012 is coaxially fixedly connected to the rotating seat 1011, and the upper end of the top telescopic joint 1016 is connected to the spraying component 102.

[0038] Reference Figure 3 and Figure 4 The liquid inlet end of the water pump 103 is connected to the water tank through a liquid inlet pipe, and the liquid outlet end of the water pump 103 is connected to a liquid outlet pipe.

[0039] A side hole and a core hole are provided at the bottom of the rotating seat 1011, and both are connected to the bottom expansion joint 1012, wherein a connecting side tube 1013 is extended from the lower hole opening of the side hole, the core hole is coaxial with the bottom expansion joint 1012, a connecting core tube 1014 is extended from the lower hole opening of the core hole, the bottom of the connecting side tube 1013 is connected to valve pipe one through rotating joint one, and the bottom of the connecting core tube 1014 is connected to valve pipe two through rotating joint two.

[0040] A switching valve 104 is provided between valve pipeline 1, valve pipeline 2 and the liquid outlet pipe. The switching valve 104 is used to connect the liquid outlet pipe with valve pipeline 1 or valve pipeline 2, which can be realized by the existing technology and will not be described in detail.

[0041] When the water pump 103 is running to draw water into the bottom expansion joint 1012, as the water continues to flow in, it will push the remaining expansion joints except the bottom expansion joint 1012 to expand, so that the upper end of the top expansion joint 1016 becomes higher, that is, the spraying member 102 becomes higher;

[0042] When the drain valve disposed on the rotating seat 1011 and connected to the bottom telescopic joint 1012 is opened, the water in the telescopic joint can be discharged, thereby retracting the telescopic joint and lowering the spraying member 102. When not in use, the volume of the device can be reduced for easier storage.

[0043] Reference Figure 4 , Figure 6 and Figure 7 The spraying component 102 includes a connecting bracket 108 arranged at the upper end of the top telescopic joint 1016, a nozzle 109 is rotatably mounted on the connecting bracket 108, and a rotating shaft 110 formed at the rotating mounting position is arranged horizontally, the nozzle 109 and the rotating shaft 110 are arranged vertically, and the rotating shaft 110 is dynamically connected to a second motor 111 arranged on the connecting bracket 108. The second motor 111 can drive the rotating shaft 110 to rotate, thereby changing the pitch angle of the nozzle 109.

[0044] A liquid outlet nozzle 1092 is arranged at the lowest point of the outer circumferential surface of the nozzle 109, and a plurality of liquid outlet nozzles 1092 are arranged in an array along the axial direction of the nozzle 109. In addition, a liquid inlet nozzle 1091 is also arranged on the outer circumferential surface of the nozzle 109, and the liquid inlet nozzle 1091 is connected to the upper orifice of the core hole by a connecting hose 107. The operation of the water pump 103 can draw water into the nozzle 109, and then output it to the outside through the liquid outlet nozzle 1092.

[0045] In a preferred embodiment, an atomizing nozzle is provided at the end of the liquid outlet nozzle 1092, which is not shown in the figure. Its significance is that the atomizing nozzle can spray water outward in an atomized manner, and the dust reduction effect is better.

[0046] In a preferred embodiment, the two ends of the nozzle 109 are respectively located on both sides of the rotating shaft 110, and a counterweight ball 112 is provided at one end of the nozzle 109. The counterweight ball 112 and the liquid outlet nozzle 1092 are respectively located on both sides of the rotating shaft 110. The significance of this is that the counterweight ball 112 plays a role of gravity balance to prevent the mobile cart 100 from tipping over after the height of the spraying component 102 is increased.

[0047] Working principle of the present invention:

[0048] The switching valve 104 connects the connecting side pipe 1013 with the liquid outlet pipe, and the water pump 103 is running to draw water into the bottom expansion joint 1012. As the water continues to flow in, it pushes the remaining expansion joints except the bottom expansion joint 1012 to expand, so that the upper end of the top expansion joint 1016 becomes higher, and the spraying member 102 becomes higher;

[0049] When the spraying member 102 reaches the preset height, the switching valve 104 connects the connecting core tube 1014 with the liquid outlet pipe, and the operation of the water pump 103 can draw water into the nozzle 109, and then output it outward through the liquid outlet nozzle 1092. At the same time, the motor 105 drives the rotating seat 1011 to rotate, and the motor 2 111 drives the nozzle 109 to reciprocate up and down around the rotating shaft 110, so as to adjust the spraying range. Of course, according to the actual situation, when it is necessary to continuously spray and reduce dust over a large area, the motor 105 and the motor 2 111 are continuously started. When it is necessary to spray and reduce dust at a certain place, after the spraying range is adjusted, the current spraying range is kept unchanged;

[0050] After the spraying and dust reduction is completed, the drain valve arranged on the rotating seat 1011 and connected to the bottom telescopic joint 1012 is opened to discharge the water in the telescopic joint, thereby retracting the telescopic joint and lowering the spraying component 102. When not in use, the volume of the device can be reduced, making it more convenient to store.

[0051] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
