[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] A dust suppression spraying device for highway maintenance includes a base 1, a housing 2, and a water tank 3. A rotating plate 4 is mounted on top of the housing 2, and a three-way pipe 5 passes through the center of the rotating plate 4. A fixing post 6 is mounted on the rotating plate 4, and an atomizing nozzle 7 is mounted on the fixing post. The atomizing nozzle 7 is connected to the three-way pipe 5 via a flexible hose 8. A lifting mechanism is installed inside the housing 2, which includes a lifting plate 101, a lifting shaft 102, a central shaft 103, and a threaded rod 104. A forward and reverse motor 11 is installed inside the housing 2, and the output end of the forward and reverse motor 11 is connected to the threaded rod 104. The central shaft 103 and the threaded rod... All 104 threads penetrate the lifting plate 101. The threaded rod 104 is threadedly connected to the lifting plate 101. Both the central rotating shaft 103 and the threaded rod 104 are equipped with transmission gears 12, which are connected by a transmission belt 13. The lifting shaft 102 is a hollow structure with an internal slide rail 14. A slider 15 is mounted at the top of the central rotating shaft 103 and slidably connected within the slide rail 14. The bottom of the lifting shaft 102 is rotatably connected to the lifting plate 101, and its upper end penetrates the housing 2. The bottom of the central rotating shaft 103 is rotatably connected to a fixed plate 16, which is located inside the housing 2. When the forward and reverse motor 11 rotates in the forward direction, the threaded rod 104 rotates, causing the lifting plate 101 to rise along with the rotating threaded rod 104, thus raising the lifting shaft 102 and the lifting plate 101. Simultaneously, through the transmission of the transmission gear 12 and the transmission belt 13, the central rotating shaft 103 rotates along with the rotation of the threaded rod 104. The slider 15 drives the lifting rotating shaft 102 and the rotating plate 4 to rotate together, so that the atomizing nozzle 7 can rotate and rise at the same time. When the forward and reverse motors 11 rotate in the opposite direction, the atomizing nozzle 7 rotates and falls at the same time, which improves the efficiency of dust suppression spraying.

[0022] The water tank 3 is connected to the water pump 17, the water pump 17 is connected to the water delivery pipe 18, the central rotating shaft 103 has a hollow structure inside, and the water delivery pipe 18 passes through the fixing plate 16 and connects the three-way pipe 5 to the water pump 17 through the interior of the central rotating shaft 103.

[0023] The atomizing nozzle 7 is equipped with threaded knobs 19 on both sides, and the threaded knobs 19 are threadedly connected to the fixing post 6. The spray angle of the atomizing nozzle 7 can be adjusted by rotating the threaded knobs 19, thereby adjusting the range of dust suppression spray.

[0024] The water tank 3 is equipped with a funnel 20, and a filter screen 21 is installed inside the water tank 3. The filter screen 21 can filter the water added to the water tank 3 to prevent impurities from clogging the atomizing nozzle 7.

[0025] The housing 2 is provided with a limit block 22 inside.

[0026] The base 1 is equipped with four casters 23 at its base and a push rod 24 on its top. This allows staff to easily adjust the position of the device.

[0027] Working principle:

[0028] After adding water to the water tank 3, the operator pushes the device to the work area. Turning the threaded knob 19 adjusts the spray angle of the atomizing nozzle 7, allowing for adjustment of the dust suppression spray range. Turning on the water pump 17 allows water from the water tank 3 to be sprayed from the atomizing nozzle 7. At this time, the forward and reverse motor 11 is activated. When the forward motor 11 rotates forward, it causes the threaded rod 104 to rotate, and the lifting plate 101 rises with the rotation of the threaded rod 104, driving the lifting shaft 102 and the lifting plate 101 to rise. Simultaneously, through the transmission gear 12 and the transmission belt 13, the central shaft 103 rotates along with the threaded rod 104, driving the lifting shaft 102 and the rotating plate 4 to rotate together via the slider 15. This allows the atomizing nozzle 7 to rotate and rise simultaneously. When the forward and reverse motor 11 rotates in the reverse direction, the atomizing nozzle 7 rotates and descends simultaneously. The atomizing nozzle 7 maintains rotation during its ascent and descent, improving the efficiency of the dust suppression spray.

Various modifications and substitutions to the present invention will be apparent to those skilled in the art after reading the above content.
