[0002] During the construction of highways, dust will be generated. These dusts are mixed in the air and inhaled by construction workers, which is likely to endanger the health of construction workers. Therefore, dust reduction devices need to be equipped at the construction site.

[0003] The patent with the publication number CN115722023A discloses a construction dust reduction device, which consists of components such as a first motor, a purification rod, a mesh plate, and a water storage tank. When the device reduces dust, it is necessary to drive the purification rod to rotate through the first motor, so that the mesh plate rotates. When the mesh plate touches the water in the water storage tank, it can lift the water, causing the water in the water storage tank to splash out, so that the dust in the air can be contacted by the splashing water to achieve the purpose of dust reduction. However, the range where the water can splash is small, so the dust reduction coverage area is limited, which makes the dust reduction effect of the device not ideal. Therefore, a dust reduction device for highway construction is now developed. Content of the Utility Model

Specific embodiments

[0023] The present utility model will be further described below with reference to the drawings and embodiments.

[0024] Embodiment 1: A dust reduction device for road construction, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, includes a trolley 1. A water storage tank 2 is fixedly connected to the upper left part of the trolley 1. Water pumps 6 are fixedly connected to the front and rear sides of the top of the water storage tank 2. The water pumps 6 are both communicated with the water storage tank 2. Telescopic pipes 3 are fixedly connected to the water pumps 6. The telescopic pipes 3 are both communicated with the adjacent water pumps 6. The tops of the telescopic pipes 3 are rotatably connected with nozzles 4. The nozzles 4 are both communicated with the adjacent telescopic pipes 3. Sealing rings are connected to the joints of the nozzles 4 and the adjacent telescopic pipes 3. A one-way valve 5 is fixedly connected to the right part of the water storage tank 2. First electric guide rods 7 are fixedly connected to the front and rear sides of the lower part of the water storage tank 2. A sliding seat 8 is slidably connected between the first electric guide rods 7. The sliding seat 8 is fixedly connected to both telescopic pipes 3. A second electric guide rod 9 is further included. The second electric guide rod 9 is fixedly connected to the middle position of the upper part of the sliding seat 8. A slider 10 is slidably connected to the second electric guide rod 9. Racks 11 are fixedly connected to the front and rear sides of the slider 10. Gears 12 are fixedly connected to the nozzles 4. The gears 12 are both meshed with the adjacent racks 11.

[0025] This device is used for dust reduction during highway construction. When in use, first connect the external water supply device to the one-way valve 5, then inject water into the water storage tank 2 through the one-way valve 5, and then remove the external water supply device. Push the whole device to the location where dust reduction work needs to be carried out, and turn on the first electric guide rod 7, the second electric guide rod 9 and the water pump 6. Under the action of the water pump 6, the water in the water storage tank 2 will be pumped into the telescopic pipe 3. At the same time, driven by the first electric guide rod 7, the sliding seat 8 will move up and down reciprocally. At this time, the sliding seat 8 will drive the telescopic pipe 3 to reciprocally expand and contract, so that the telescopic rod drives the nozzle 4 to move up and down reciprocally. At the same time, driven by the second electric guide rod 9, the slider 10 will move left and right reciprocally. Driven by the slider 10, the rack 11 will move left and right reciprocally, and the rack 11 drives the gear 12 and the nozzle 4 to rotate. In this way, it can be realized that while the nozzle 4 sprays water, it moves up and down reciprocally and rotates reciprocally at the same time, so as to expand the spraying range of the nozzle 4, and thus expand the dust reduction range of this device. When dust reduction work is not required, the first electric guide rod 7, the second electric guide rod 9 and the water pump 6 can be turned off. When the nozzle 4 of this device sprays water, the telescopic rod is driven by the first electric guide rod 7 to reciprocally expand and contract, which can make the nozzle 4 move up and down reciprocally. And through the cooperation of the gear 12 and the rack 11, the nozzle 4 can be made to rotate reciprocally, which can expand the spraying range of the nozzle 4, and thus expand the dust reduction range.

[0026] Embodiment 2: On the basis of Embodiment 1, as Figure 1 and Figure 5 shown, the dust reduction device for highway construction further includes a mounting seat 13. The number of mounting seats 13 is two, and the two mounting seats 13 are respectively fixedly connected to the two nozzles 4. Air collectors 14 are rotatably connected to both the upper and lower sides of the mounting seat 13.

[0027] As Figure 1 and Figure 5 shown, the dust reduction device for highway construction further includes a first filter screen 15. The first filter screen 15 is slidably connected to both the upper and lower sides of the two mounting seats 13.

[0028] As Figure 5 shown, the dust reduction device for highway construction further includes a clamping block 16. The clamping blocks 16 are symmetrically and slidably connected to both the upper and lower sides of the mounting seat 13. Three springs 17 are connected between the clamping block 16 and the adjacent mounting seat 13. The adjacent first filter screen 15 can be limited by the clamping block 16.

[0029] To further expand the water spraying range, the wind can be used to make the water spray farther. Thus, the air collecting fan 14 can be turned on to make the air collecting fan 14 rotate. The air collecting fan 14 can blow air into the mounting seat 13, and the water in the nozzle 4 will also be sprayed out through the mounting seat 13. In this way, the air collecting fan 14 can provide wind power for the water, thereby pushing the water to spray to a farther position and achieving the purpose of further expanding the water spraying range. When the dust suppression work is over, the air collecting fan 14 can be turned off. Also, since the first filter screen 15 is provided on the mounting seat 13, the first filter screen 15 can block the external dust and prevent the dust from being directly sucked into the mounting seat 13 and mixed with the water to form mud, thereby avoiding the blockage of the mounting seat 13 by the mud. In the initial state, the first filter screen 15 is in a state of being limited by the clamping block 16. When it is necessary to take out the first filter screen 15 and clean the first filter screen 15, the clamping block 16 needs to be moved to the side away from the first filter screen 15, and the spring 17 is compressed. At this time, the first filter screen 15 is released, and then the first filter screen 15 is pulled out from the mounting seat 13. After releasing the clamping block 16, under the action of the spring 17, the clamping block 16 moves in the reverse direction to reset and limit the first filter screen 15. After cleaning, refer to the previous operation steps to open the clamping block 16, compress the spring 17, install the first filter screen 15 back to its original position on the mounting seat 13, release the clamping block 16, and under the action of the spring 17, the clamping block 16 limits the first filter screen 15 again.

[0030] As Figure 1 , Figure 6 and Figure 7 shown, the dust suppression device for road construction further includes a mounting box 21. The mounting box 21 is fixedly connected to the upper right part of the trolley 1. A collecting frame 23 is slidably connected to the mounting box 21. A dust suction box 18 is fixedly connected to the bottom of the trolley 1. A dust suction pipe 19 is fixedly connected to the dust suction box 18. The dust suction pipe 19 is communicated with the dust suction box 18. The dust suction pipe 19 is communicated with the mounting box 21. The dust suction pipe 19 is fixedly connected to the trolley 1. An air pump 20 is fixedly connected to the dust suction pipe 19.

[0031] As Figure 6 and Figure 7 shown, the dust suppression device for road construction further includes a second filter screen 22. The second filter screen 22 is fixedly connected to the upper part of the mounting box 21.

[0032] To make less dust scattered at the construction site, the air pump 20 can be turned on so that the air pump 20 absorbs the surrounding dust through the dust suction pipe 19 and the dust suction box 18. The dust will be sucked into the collecting frame 23. The purpose of setting the second filter screen 22 is to ventilate, so as to balance the air pressure inside and outside the mounting box 21. When the dust suppression work is over, turn off the air pump 20, pull the collecting frame 23 forward out of the mounting box 21, clean the collecting frame 23, and then push the collecting frame 23 back into the mounting box 21.

[0033] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
