Description

Technical Field

[0001] This utility model belongs to the field of road construction technology, and in particular relates to a road construction dust control device. Background Technology

[0002] Road construction refers to the work of repairing, reconstructing, or constructing new roads on existing roads. Before road construction, the roadbed needs to be treated, including earthwork excavation, filling, and compaction. However, the construction process generates a significant amount of dust. Current methods for controlling road construction dust typically involve water spraying. For example, a road construction dust control device (patent number CN220939839U) uses a handcart to push a bucket of water and a single nozzle connected to the bucket, spraying the road surface through the reciprocating oscillation of the nozzle. Alternatively, a road construction dust control device (patent number CN221107548U) uses a single spray bar installed on the roadside, also spraying the road surface through the reciprocating oscillation of the nozzle. However, both of these methods rely on a single nozzle, resulting in relatively low spraying efficiency. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned technical problems by providing a road construction dust control device that is applicable to different working conditions and offers greater flexibility and versatility.

[0004] In view of this, the present invention provides a road construction dust control device, including a frame, on which are arranged: Water storage tanks are used to store water. The water spray assembly includes an inlet pipe assembly, one end of which is submerged in a water storage tank and connected to a water pump. The other end of the inlet pipe assembly is connected to multiple adapter pipes along the length of the frame. The adapter pipes are fixedly mounted on the frame. Each adapter pipe has an upper nozzle parallel to the ground at its upper end and a lower nozzle facing the ground at its lower end. The casters are connected to the bottom of the frame.

[0005] In this technical solution, the road construction dust control device can be configured in two ways. One method involves placing a dust control device on each side of the road, with only the upper nozzles spraying water onto the road. The device can also be moved along the length of the road by casters. The other method involves placing the device across the road surface, with only the lower nozzles spraying water onto the road, or the upper nozzles also spraying water simultaneously. This method allows for a larger water volume per unit area and a wider coverage area across the road cross-section, making it suitable for conditions with severe dust pollution. These two spraying methods are applicable to different working conditions, offering greater flexibility and versatility.

[0006] Furthermore, the water inlet pipe assembly includes a water inlet pipe and a transfer pipe. The transfer pipe is arranged along the length of the frame, and the water inlet pipe extends from the transfer pipe toward the bottom of the water storage tank. Each transfer pipe is connected to the transfer pipe.

[0007] Furthermore, each upper and lower nozzle is connected to a valve, and each upper and lower nozzle controls the start and stop of water spraying through different valves.

[0008] Furthermore, a filter screen is provided on the outside of the lower nozzle.

[0009] In this technical solution, the lower nozzle sprays water directly onto the road surface and is closest to the road surface. When moving and sprinkling water along the construction road, the lower nozzle will easily come into contact with dust on the road surface. The dust may cause some blockage of the spray holes of the lower nozzle, thereby affecting the overall sprinkling effect of the spray head and reducing the overall dust handling efficiency during construction. Setting a filter screen can filter out some dust and prevent dust from entering the spray holes of the lower nozzle.

[0010] Furthermore, a screen cleaning assembly is installed on the frame, which can simultaneously clean the filter screen on each lower nozzle.

[0011] In this technical solution, the dust on the filter screen can be clearly removed by setting up the screen cleaning component, thereby increasing the service life of the filter screen.

[0012] Furthermore, the network clearing component includes: The screen cleaning base is fixedly installed below the water storage tank on the frame. The screen cleaning base has two first rotating shafts and second rotating shafts that are parallel to each other and are arranged along the length of the frame. The two ends of the first rotating shafts extend into the frame, and the second rotating shafts have screen cleaning thread holes that are perpendicular to the circumference. The screen cleaning screw is threaded through the second rotating shaft and connected to the screen cleaning threaded hole. One end of the screen cleaning screw is inserted into the moving shaft and is axially fixedly connected to the moving shaft, and is circumferentially rotatably connected. The moving shaft is parallel to the first rotating shaft. The cleaning rod is provided in multiple ways, with each lower nozzle corresponding to one cleaning rod. The cleaning rod is generally L-shaped and includes a first rod segment and a second rod segment. The first rod segment has a first connecting hole and a second connecting hole near its two ends, respectively. The end of the second rod segment away from the second connecting hole is used to contact the filter screen. The first rotating shaft passes through the first connecting hole and is fixedly connected to the cleaning rod, and the moving shaft passes through the second connecting hole and is rotatably connected to the cleaning rod.

[0013] In this technical solution, when screen cleaning is required, the screen cleaning screw is manually rotated within the screen cleaning threaded hole of the second rotating shaft. This causes the end of the screen cleaning screw, along with the moving shaft, to move, causing the screen cleaning rod and the first rotating shaft to rotate together around the axis of the first rotating shaft. This allows the second rod segment to gradually approach the filter screen until it impacts the filter screen, shaking off the accumulated dust. This structure uses a screw thread design, which can accommodate nozzles of different sizes. Furthermore, when screen cleaning is not required, the screen cleaning rod can be moved away from the lower nozzle without affecting the spraying effect. The position of the screen cleaning screw is also ergonomically designed.

[0014] Furthermore, a total of six transfer pipes are provided, with a distance of 0.8 meters between any two adjacent transfer pipes.

[0015] Furthermore, the distance between the two casters along the length of the frame is 4.5 meters.

[0016] In this technical solution, the standard width meets the requirements of the lane.

[0017] Furthermore, the water tank is provided with handholds on both sides and the back.

[0018] In this technical solution, the handheld part makes it easy for the operator to push and pull the dust removal device.

[0019] Furthermore, the dust control method includes the following steps: S1: Fill the water tank with water and move the road construction dust control device to the side of the road or across the road. S2: Turn on the water pump and open the valves of the upper and lower nozzles as needed.

[0020] S3: Regularly use the cleaning kit to clean the filter screen on the lower nozzle.

[0021] The beneficial effects of this utility model are: 1. This road construction dust control device can be installed in two ways. One way is to place it on the roadside, with one device on each side of the road. Only the upper nozzle sprays water onto the road, and the frame can be moved along the length of the road as the road construction progresses. The other way is to place the device across the road surface, with only the lower nozzle spraying water onto the road, or the upper nozzle also spraying water simultaneously. This method results in a larger water volume per unit area and a wider coverage area across the road cross-section, making it suitable for conditions with severe dust. These two spraying methods are applicable to different working conditions, offering greater flexibility and versatility.

[0022] 2. Installing a filter screen can filter out some dust, preventing it from entering the spray holes of the lower nozzle. The filter cleaning component can remove dust from the filter screen, extending its service life.

[0023] 3. The screen cleaning assembly adopts a screw thread structure, which can adapt to nozzles of different specifications. Furthermore, this structure allows the screen cleaning rod to be moved away from the lower nozzle when screen cleaning is not required, without affecting the spraying effect. In addition, the position of the screen cleaning screw is ergonomically designed. Attached Figure Description

Additionally, features described with reference to certain examples may be combined in other examples.

[0031] Example 1 like Figure 1-4 As shown, a road construction dust control device includes a frame 1, on which a water storage tank 2, a water spray assembly 3, and casters 4 are mounted. The casters 4 are connected to the bottom of the frame 1. The water storage tank 2 is used to store water. The water spray assembly 3 includes an inlet pipe assembly 5. One end of the inlet pipe assembly 5 is submerged in the water storage tank 2 and connected to a water pump. The other end of the inlet pipe assembly 5 is connected to multiple transfer pipes 8 along the length of the frame 1. The inlet pipe assembly 5 includes a lead pipe 6 and a transfer pipe 7. The transfer pipe 7 is arranged along the length of the frame 1. The lead pipe 6 extends from the transfer pipe 7 towards the bottom of the water storage tank 2. Each transfer pipe 8 is connected to the transfer pipe 7. The transfer pipes 8 are fixedly mounted on the frame 1. Each transfer pipe 8 has an upper nozzle 9 parallel to the ground at its upper end and a lower nozzle 10 facing the ground at its lower end. Each upper nozzle 9 and lower nozzle 10 is connected to a valve 11, and each upper nozzle 9 and lower nozzle 10 controls the start and stop of the water spray through a different valve 11. A filter screen 12 is provided on the outside of the lower nozzle 10. Handholds are provided on both sides and the back of the water storage tank 2. The handle makes it easy for the operator to push and pull the dust removal device.

[0032] This road construction dust control device offers two dust suppression methods. One method involves placing one device on each side of the road, with only the upper nozzle 9 spraying water onto the road. The frame 1 is propelled by casters 4, allowing it to move along the road's length as construction progresses. The other method involves placing the device across the road surface, with only the lower nozzle 10 spraying water, or the upper nozzle 9 also spraying water simultaneously. This method provides a larger water volume per unit area and a wider coverage area across the road's cross-section, making it suitable for conditions with severe dust pollution. These two spraying methods cater to different working conditions, offering greater flexibility and versatility. Six transfer pipes 8 are installed, with a distance of 0.8 meters between adjacent transfer pipes 8. The distance between two casters 4 along the length of the frame 1 is 4.5 meters, meeting the standard width requirements for the lane.

[0033] Example 2 like Figure 5-7 As shown, the lower nozzle 10 sprays water directly onto the road surface and is closest to the road surface. When moving and sprinkling water along the construction road, the lower nozzle 10 will easily come into contact with dust on the road surface. The dust may cause some blockage of the spray holes of the lower nozzle 10, thereby affecting the overall sprinkling effect of the spray head and reducing the overall dust handling efficiency during construction. The filter screen 12 can filter out some dust and prevent dust from entering the spray holes of the lower nozzle 10.

[0034] A screen cleaning assembly 13 is installed on the frame 1, which can simultaneously clean the dust from the filter screen 12 on each lower nozzle 10. By installing the screen cleaning assembly 13, the dust on the filter screen 12 can be removed, thus extending the service life of the filter screen 12.

[0035] The network clearing component 13 includes: Cleaning screen base 14 is fixedly installed below the water storage tank 2 on the frame 1. Two first rotating shafts 15 and second rotating shafts 16 are arranged parallel to each other along the length of the frame 1. The two ends of the first rotating shaft 15 extend into the frame 1. The second rotating shaft 16 has cleaning screen threaded holes 17 perpendicular to the circumference. The screen cleaning screw 18 is threaded through the second rotating shaft 16 and connected to the screen cleaning threaded hole 17. One end of the screen cleaning screw 18 is inserted into the moving shaft 19 and is axially fixedly connected to the moving shaft 19, and circumferentially rotatably connected. The moving shaft 19 is parallel to the first rotating shaft 15. The cleaning rod 20 is provided in multiple ways, with each lower nozzle 10 corresponding to one cleaning rod 20. The cleaning rod 20 is generally L-shaped and includes a first rod segment 21 and a second rod segment 22. The first rod segment 21 has a first connecting hole 23 and a second connecting hole 24 near its two ends, respectively. The end of the second rod segment 22 away from the second connecting hole 24 is used to contact the filter screen 12. The first rotating shaft 15 passes through the first connecting hole 23 and is fixedly connected to the cleaning rod 20. The moving shaft 19 passes through the second connecting hole 24 and is rotatably connected to the cleaning rod 20.

[0036] When screen cleaning is required, manually rotate the screen cleaning screw 18 within the screen cleaning threaded hole 17 of the second rotating shaft 16. This causes the end of the screen cleaning screw 18, along with the moving shaft 19, to move, causing the screen cleaning rod 20 and the first rotating shaft 15 to rotate together around the axis of the first rotating shaft 15. This allows the second rod segment 22 to gradually approach the filter screen 12 until it impacts the filter screen 12, shaking off the accumulated dust. This structure, using a screw thread, can accommodate nozzles of different sizes. Furthermore, when screen cleaning is not required, the screen cleaning rod 20 can be moved away from the lower nozzle 10 without affecting the spraying effect. The position of the screen cleaning screw 18 is also ergonomically designed.

[0037] Dust control methods include the following steps: S1: Fill the water tank 2 with water and move the road construction dust control device to the side of the road or across the road. S2: Turn on the water pump and open valve 11 of the upper nozzle 9 and lower nozzle 10 as needed.

[0038] S3: Use the cleaning assembly 13 regularly to clean the filter screen 12 on the lower nozzle 10.

[0039] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
