[0002] During the process of highway construction, the extensive use of lime, sand and soil, as well as the use of large engineering vehicles, makes the air filled with dust particles and other pollutants. These large amounts of dust particles floating in the air not only affect human health but also cause environmental pollution. Therefore, a dust suppression device for construction is needed to reduce the dust at the construction site. A dust suppression device for highway application is a device used to reduce road dust and improve air quality. It generally suppresses the generation of dust on the road through water mist, spraying agents or other dust reduction measures. The use of a highway dust reduction device can effectively reduce the impact of road dust on the surrounding environment and human health, improve air quality, and enhance the safety of driving.

[0018] From the above technical solutions, it can be seen that the present application has the following beneficial effects:

[0019] 1: Start the motor to drive the third rotating shaft to rotate. When the third rotating shaft rotates, it drives the incomplete gear to rotate. When the incomplete gear rotates to mesh with the driving tooth plate, it drives the driving tooth plate and the moving tooth plate to move upward. When the moving tooth plate moves upward, it drives the second gear, the second gear, and the connecting plate to rotate around the first rotating shaft. When the connecting plate rotates, it drives the cross plate and the placement plate to rotate longitudinally, so as to adjust the longitudinal angle of the atomizing nozzle. When the incomplete gear rotates to separate from the driving tooth plate, under the gravity of the placement plate, the cross plate, and the L-shaped rod, it will rotate downward, and the cross plate and the placement plate rotate around the first rotating shaft. At this time, the atomizing nozzle rotates downward longitudinally. Repeating this way, the atomizing nozzle can longitudinally swing during spraying, thereby increasing the longitudinal spraying range of the atomizing nozzle.

[0020] 2: When the moving tooth plate moves, it drives the second hinge seat to move. When the second hinge seat moves, it drives the rotating rod to rotate. When the rotating rod rotates, it drives the third tooth plate to move. When the third tooth plate moves, it drives the fourth gear to rotate. When the fourth gear rotates, it drives the second rotating shaft to rotate. When the second rotating shaft rotates, it drives the third gear to rotate. When the third gear rotates, it drives the second tooth plate and the first tooth plate to move. When the first tooth plate moves, it drives the first gear to rotate. When the first gear rotates, it drives the L-shaped rod to swing horizontally, thereby increasing the horizontal spraying range of the atomizing nozzle.

[0021] 3: When the moving tooth plate moves up and down, it not only drives the second gear to rotate, but also drives the second hinge seat to move accordingly. When the second gear rotates, it drives the first rotating shaft, the connecting plate, the cross plate, and the placement plate to rotate, that is, to adjust the longitudinal angle of the atomizing nozzle. When the second hinge seat moves, it drives the rotating rod to rotate, and then drives the third tooth plate to move. When the third tooth plate moves to drive the fourth gear and the third gear to rotate, and then drives the second tooth plate and the first tooth plate to move, it can drive the first gear and the atomizing nozzle to rotate, thereby adjusting the horizontal angle of the atomizing nozzle. That is, when the moving tooth plate moves up and down, it can not only adjust the longitudinal angle of the atomizing nozzle, but also synchronously adjust the horizontal angle of the atomizing nozzle, so that the water mist sprayed by the atomizing nozzle is wavy, which can better play the role of dust suppression.

[0035] Refer to Figures 1-7 :

[0036] As an embodiment of the present invention, a dust suppression device for highway construction is provided, which includes a main body unit 100 and a driving unit 200. The main body unit 100 includes a bottom plate 101. A plurality of mounting holes are provided on the bottom plate 101, and bolts can be used to fix the bottom plate 101 at the required position, increasing the stability of the device during use. A hollow support cylinder 102 is fixed on the top of the bottom plate 101. A support tooth plate 103 is slidably connected inside the hollow support cylinder 102. A rectangular cylinder 104 is fixed on the top of the support tooth plate 103. A horizontal plate 105 is arranged on one side of the rectangular cylinder 104. A storage plate 106 is fixed on the side of the horizontal plate 105 away from the rectangular cylinder 104. A plurality of L-shaped rods 107 are rotatably connected at equal intervals inside the storage plate 106. A rigid tube 108 is fixed at one end of the L-shaped rod 107. An atomizing nozzle 109 is installed at the end of the rigid tube 108 away from the L-shaped rod 107. A hose 110 is fixed and communicated with each of the plurality of rigid tubes 108. The driving unit 200 includes a first tooth plate 201. The first tooth plate 201 is arranged above the storage plate 106. A first gear 202 is fixed on the outer side of the L-shaped rod 107. Each of the plurality of first gears 202 meshes with the first tooth plate 201. A second tooth plate 203 is fixed on the side of the first tooth plate 201 away from the first gear 202. An adjustment assembly for adjusting the longitudinal angle of the atomizing nozzle 109 is arranged inside the rectangular cylinder 104. An adjustment assembly for adjusting the horizontal angle of the atomizing nozzle 109 is arranged at the bottom of the horizontal plate 105. When the adjustment assembly works, it can drive the adjustment assembly to work simultaneously.

[0037] Among them, a hollow plate 111 is fixed and communicated with one side of the top of the hollow support cylinder 102. A positioning tooth plate 112 is slidably connected inside the hollow plate 111. The positioning tooth plate 112 meshes with the support tooth plate 103. A pull rod 113 is fixed on one side of the positioning tooth plate 112. The pull rod 113 penetrates through the hollow plate 111 and slides inside the hollow plate 111. A handle 115 is fixed at the end of the pull rod 113 extending outside the hollow plate 111. An elastic member 114 is sleeved on the outer side of the pull rod 113. One end of the elastic member 114 abuts against the positioning tooth plate 112, and the other end of the elastic member 114 abuts against the inner wall of the hollow plate 111. It should be noted that the elastic member 114 can use devices such as springs, and in the normal state of the elastic member 114, the positioning tooth plate 112 meshes with the support tooth plate 103.

[0038] In use, first, according to the height required for spraying, pull the handle 115 to drive the pull rod 113 to move. When the pull rod 113 moves, it drives the positioning tooth plate 112 to move. After the positioning tooth plate 112 is separated from the support tooth plate 103, the support tooth plate 103 can be moved up and down. When the support tooth plate 103 moves, it drives the rectangular cylinder 104 to move. When the rectangular cylinder 104 moves, it drives the cross plate 105 to move. When the cross plate 105 moves, it drives the object placing plate 106 to move, and further drives the rigid pipe 108 and the atomizing nozzle 109 to move, so as to adjust the height of the atomizing nozzle 109 to meet the requirements of different spraying heights. It should be noted that the flexible hose 110 is connected to an external water supply device.

[0039] In addition, a third rotating shaft 226 is rotatably connected inside the rectangular cylinder 104. An incomplete gear 227 is fixed on the outer side of the third rotating shaft 226. A motor 228 is installed on one side of the rectangular cylinder 104. One end of the third rotating shaft 226 extending outside the rectangular cylinder 104 is fixed to the output end of the motor 228. A driving tooth plate 225 is fixed to the bottom of the moving tooth plate 208, and the incomplete gear 227 meshes with the moving tooth plate 208.

[0040] It should be noted that the motor 228 in this embodiment is a conventional device well-known to those skilled in the art purchased on the market, and the model can be selected or customized according to actual needs. In this patent, we only use it and do not improve its structure and function. For those skilled in the art, its setting method, installation method, and electrical connection method only need to be debugged and operated according to the requirements of its user manual, and will not be elaborated here. Moreover, the motor 228 is provided with a control switch matching it, and the installation position of the control switch is selected according to actual use requirements to facilitate operation and control by the operator.

[0041] Furthermore, the adjustment component includes a groove 204 opened at the top of the rectangular cylinder 104. A first rotating shaft 205 is rotatably connected inside the groove 204. A second gear 206 is fixed on the outer side of the first rotating shaft 205. Two connecting plates 207 are fixed on the outer side of the first rotating shaft 205. The second gear 206 is located between the two connecting plates 207. One end of each of the two connecting plates 207 away from the first rotating shaft 205 is fixed to the cross plate 105. A moving tooth plate 208 is slidably connected inside the rectangular cylinder 104, and the moving tooth plate 208 meshes with the second gear 206.

[0042] During use, start the motor 228 to drive the third rotating shaft 226 to rotate. When the third rotating shaft 226 rotates, it drives the incomplete gear 227 to rotate. When the incomplete gear 227 rotates to mesh with the driving tooth plate 225, it drives the driving tooth plate 225 to move upward. When the driving tooth plate 225 moves upward, it drives the moving tooth plate 208 to move upward. When the moving tooth plate 208 moves upward, it drives the second gear 206 to rotate. When the second gear 206 rotates, it drives the first rotating shaft 205 to rotate. When the first rotating shaft 205 rotates, it drives the connecting plate 207 to rotate around the first rotating shaft 205. When the connecting plate 207 rotates, it drives the cross plate 105 to rotate longitudinally, thereby driving the object placing plate 106 to rotate longitudinally. When the object placing plate 106 rotates longitudinally, the longitudinal angle of the atomizing nozzle 109 can be adjusted. When the incomplete gear 227 rotates to separate from the driving tooth plate 225, under the action of the gravity of the object placing plate 106, the cross plate 105, and the L-shaped rod 107, it will rotate downward, and the cross plate 105 and the object placing plate 106 rotate around the first rotating shaft 205. At this time, the atomizing nozzle 109 rotates downward longitudinally. Then, when the incomplete gear 227 rotates to mesh with the driving tooth plate 225 again, it can drive the moving tooth plate 208 to move upward again. Repeating this process enables the atomizing nozzle 109 to swing longitudinally during spraying, thereby increasing the longitudinal spraying range of the atomizing nozzle 109.

[0043] In addition, a second rotating shaft 209 is rotatably connected inside the cross plate 105. A third gear 210 and a fourth gear 211 are respectively fixed to the top and bottom of the second rotating shaft 209. The third gear 210 and the fourth gear 211 are respectively located at the top and bottom of the cross plate 105. The third gear 210 meshes with the second tooth plate 203. A second hinge seat 217 is fixed to the bottom of the moving tooth plate 208. A stroke groove 219 is formed in the rectangular cylinder 104. The second hinge seat 217 is slidably fitted in the stroke groove 219. Two first convex plates 212 are fixed to the bottom of the cross plate 105. A first limiting plate 213 is jointly fixed between the two first convex plates 212. It should be noted that due to the setting of the first limiting plate 213, the moving path of the third tooth plate 214 is restricted, so that the third tooth plate 214 is always in a meshing state with the fourth gear 211 when it moves.

[0044] Specifically, the adjusting assembly includes a third toothed plate 214 disposed at the bottom of the cross plate 105. The third toothed plate 214 meshes with the fourth gear 211. The first limiting plate 213 penetrates through the third toothed plate 214, and the third toothed plate 214 is slidably fitted outside the first limiting plate 213. A side plate 215 is fixed to one side of the third toothed plate 214, and a first hinge seat 216 is fixed to the bottom of the side plate 215. A rotating rod 218 is hinged inside the first hinge seat 216. One end of the rotating rod 218 away from the first hinge seat 216 is hinged to the second hinge seat 217. Two second protrusions 229 are fixed to the top of the storage plate 106, and a second limiting plate 230 is jointly fixed between the two second protrusions 229. The second limiting plate 230 penetrates through the first toothed plate 201, and the first toothed plate 201 is slidably fitted outside the second limiting plate 230. It should be noted that due to the setting of the second limiting plate 230, the moving path of the first toothed plate 201 is restricted, so that the first toothed plate 201 is always in a meshing state with the first gear 202 when moving.

[0045] During use, when the moving toothed plate 208 moves upward, it drives the second hinge seat 217 to move upward. When the second hinge seat 217 moves upward, it drives the rotating rod 218 to rotate. When the rotating rod 218 rotates, it drives the third toothed plate 214 to move. When the third toothed plate 214 moves, it drives the fourth gear 211 to rotate. When the fourth gear 211 rotates, it drives the second rotating shaft 209 to rotate. When the second rotating shaft 209 rotates, it drives the third gear 210 to rotate. When the third gear 210 rotates, it drives the second toothed plate 203 and the first toothed plate 201 to move. When the first toothed plate 201 moves, it drives the first gear 202 to rotate. When the first gear 202 rotates, it drives the L-shaped rod 107 to swing horizontally. When the L-shaped rod 107 swings horizontally, it drives the atomizing nozzle 109 to swing horizontally, thereby expanding the horizontal spraying range of the atomizing nozzle 109. When the moving toothed plate 208 moves downward, it drives the second hinge seat 217 to move downward. When the second hinge seat 217 moves downward, it drives the rotating rod 218 to rotate in the reverse direction. When the rotating rod 218 rotates in the reverse direction, it drives the third toothed plate 214 to move in the reverse direction, thereby driving the fourth gear 211 and the third gear 210 to rotate in the reverse direction. When the third gear 210 rotates in the reverse direction, it drives the second toothed plate 203 and the first toothed plate 201 to move in the reverse direction, thereby driving the L-shaped rod 107 to rotate in the reverse direction, that is, driving the atomizing nozzle 109 to rotate in the reverse direction. Repeating this way can drive the atomizing nozzle 109 to swing horizontally, thereby increasing the horizontal spraying range of the atomizing nozzle 109.

[0046] It is worth mentioning that when the movable toothed plate 208 moves up and down, it not only drives the second gear 206 to rotate, but also drives the second hinge seat 217 to move accordingly. When the second gear 206 rotates, it drives the first rotating shaft 205, the connecting plate 207, the cross plate 105, and the storage plate 106 to rotate accordingly, that is, to adjust the longitudinal angle of the atomizing nozzle 109. When the second hinge seat 217 moves, it drives the rotating rod 218 to rotate, and further drives the third toothed plate 214 to move. When the third toothed plate 214 moves, it drives the fourth gear 211 and the third gear 210 to rotate, and further drives the second toothed plate 203 and the first toothed plate 201 to move, so as to drive the first gear 202 and the atomizing nozzle 109 to rotate, thereby adjusting the lateral angle of the atomizing nozzle 109. That is, when the movable toothed plate 208 moves up and down, it can not only adjust the longitudinal angle of the atomizing nozzle 109, but also synchronously adjust the lateral angle of the atomizing nozzle 109, so that the water mist sprayed by the atomizing nozzle 109 is wavy, which can better play the role of dust reduction.

[0047] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention.
