[0002] In order to reduce the impact of dust on the surrounding environment during road construction, it is necessary to install spraying equipment on both sides of the road to suppress dust by spraying clean water.
[0003] During road construction, large machinery is sometimes required to enter the site. The spraying equipment installed on both sides of the road is not easy to move and can easily affect the normal movement of large machinery. In addition, since the road surface needs to be paved with multiple layers such as roadbed, concrete, asphalt, etc., water retention operations are required between different materials and after the paving is completed. Other equipment is also needed to carry out road watering operations. Therefore, a spraying dust suppression device that is easy to move and can also be switched to perform water retention operations on the road surface is proposed. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a dust suppression spraying device for road construction.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A dust suppression spraying device for road construction includes a base and a fixing box. The base has an installation groove on one side of its top. A rotating block is rotatably connected to the center of the installation groove. A column is fixedly connected to the top of the rotating block. A water pipe connector is fixedly installed on one side of the column's center. A water outlet is fixedly connected to the center of the column's top. The fixing box is fixedly installed on the top of the column. The top of the water outlet extends into the bottom of the fixing box. A fan-shaped block is rotatably connected to the top of the fixing box. An arc-shaped sealing groove is formed at the bottom of the fan-shaped block. A first inlet is formed on one side of the arc-shaped sealing groove, and a second inlet is formed on the other side. A spray head is fixedly installed on the outer wall of the bottom of the fixing box, and a sprinkler head is fixedly installed on the outer wall of the top of the fixing box. A hose connects the first inlet and the spray head to one side of the bottom of the fan-shaped block, and a hose connects the second inlet and the sprinkler head to one side of the top of the fan-shaped block.
[0006] Preferably, the base has recessed grooves on both sides, and bolt holes are provided at the bottom of the two recessed grooves.
[0007] Preferably, the top of the base away from the mounting groove is fixedly connected to an inclined first fixing seat. The top of the first fixing seat has a through groove, and the two sides of the through groove are slidably connected to a locking rod through a through hole. A limit hole is opened on one side of the locking rod.
[0008] Preferably, a second fixing seat is fixedly connected to the bottom of the column near the first fixing seat, and a rotating handle is rotatably connected to one side of the second fixing seat. The rotating handle has several locking holes that are adapted to the locking rod.
[0009] Preferably, the outlet has slots on both sides that slide to connect with the arc-shaped sealing groove, and the outlet and the water pipe joint are connected through the internal pipe of the column.
[0010] Preferably, an arc-shaped rod is fixedly connected to one side of the sector block, and an arc-shaped sleeve is fixedly connected to the top of the inner wall of the fixing box. The top of the arc-shaped rod is slidably connected to the bottom of the arc-shaped sleeve. A spring is provided inside the arc-shaped sleeve, and the two ends of the spring abut against the top of the arc-shaped rod and the inner wall of the top of the arc-shaped sleeve, respectively.
[0011] Preferably, the two ends of the same steel wire rope are fixedly connected to both sides of the fan-shaped block, and the steel wire rope passes through the top and side wall of the fixed box through the guide block respectively.
[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model features a fan-shaped block. An external water pump delivers clean water to the fan-shaped block via a water pipe connector and outlet for distribution. The first inlet and the second inlet are connected to a spray head and a sprinkler head, respectively. During road construction, rotating the fan-shaped block connects the first inlet to the outlet, allowing the clean water to be atomized through the spray head for dust suppression. After one layer of road is laid or construction is completed, rotating the fan-shaped block connects the second inlet to the outlet, allowing the clean water to flow through the sprinkler head for water spraying and moisture retention on the road surface. This design effectively suppresses dust and retains moisture on the road surface, enriching the function of the support column and eliminating the need for additional water trucks or other equipment for water retention.
[0013] This utility model uses a rotating handle, a locking rod, and a first fixed seat to lock the rotating handle, so that the rotating handle can support the column and make it easy to adjust the angle of the column.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] Reference Figure 1-6A dust suppression spraying device for road construction includes a base 1 and a fixing box 16. A mounting groove 4 is provided on one side of the top of the base 1. A rotating block 5 is rotatably connected to the middle of the mounting groove 4. A column 6 is fixedly connected to the top of the rotating block 5. A water pipe connector 10 is fixedly installed on one side of the middle of the column 6. A water outlet 14 is fixedly connected to the center of the top of the column 6. The fixing box 16 is fixedly installed on the top of the column 6. The top of the water outlet 14 extends into the bottom of the fixing box 16. A fan-shaped block 17 is rotatably connected to the top of the fixing box 16. An arc-shaped sealing groove 18 is provided at the bottom of the fan-shaped block 17. A first inlet 19 is provided on one side of the arc-shaped sealing groove 18, and a second inlet 20 is provided on the other side. A spray head 21 is fixedly installed on the outer wall of the bottom of the fixing box 16, and a sprinkler head 22 is fixedly installed on the outer wall of the top of the fixing box 16. One side wall of the bottom of the fan-shaped block 17 is connected to the first inlet 19 and the spray head 21 via a flexible hose. One side wall of the top of the fan-shaped block 17 is connected to the second inlet 20 and the sprinkler head 22 via a flexible hose. Clean water is pumped through water pipe joint 10 and outlet 14 to the fan-shaped block 17 for distribution via an external water pump. The first inlet 19 and the second inlet 20 are connected to the spray head 21 and the sprinkler head 22, respectively. During the road construction phase, rotating the fan-shaped block 17 connects the first inlet 19 to the outlet 14, allowing the clean water to be atomized through the spray head 21 to suppress dust. After one layer of road is laid or the construction is completed, rotating the fan-shaped block 17 connects the second inlet 20 to the outlet 14, allowing the clean water to be sprayed onto the road surface through the sprinkler head 22 to maintain water quality. This system can suppress dust and maintain water quality on the road surface, enriching the function of the column 6 and eliminating the need for additional equipment such as water trucks for water retention.
[0018] As a technical optimization of this utility model, the base 1 has recessed grooves 2 on both sides, and bolt holes 3 are provided at the bottom of the two recessed grooves 2. The bolt holes 3 facilitate the fixed installation of the base 1 to the foundation.
[0019] As a technical optimization of this utility model, a first fixed seat 7 with an inclined arrangement is fixedly connected to the top of the base 1 on the side away from the mounting groove 4. The top of the first fixed seat 7 has a through groove, and a locking rod 8 is slidably connected to both sides of the through groove through through holes. A limit hole 9 is opened on one side of the locking rod 8. The locking rod 8 and the first fixed seat 7 are used to lock the rotating handle 12, so that the rotating handle 12 can support the column 6, thereby facilitating the angle adjustment of the column 6.
[0020] As a technical optimization of this utility model, a second fixing seat 11 is fixedly connected to the bottom of the column 6 near the first fixing seat 7. A rotating handle 12 is rotatably connected to one side of the second fixing seat 11. The rotating handle 12 has several locking holes 13 that are adapted to the locking rod 8. The rotating handle 12 and the locking holes 13, together with the locking rod 8, can adjust the angle of the column 6. This allows the column 6 to be positioned away from the road to facilitate the passage of large machinery, and also allows the column 6 to be positioned close to the road to facilitate the water sprinkler head 22 to spray water and maintain the road surface.
[0021] As a technical optimization of this utility model, slots 15 are provided on both sides of the water outlet 14 to slide and connect with the sides of the arc-shaped sealing groove 18. The water outlet 14 and the water pipe connector 10 are connected through the internal pipe of the column 6. The arc-shaped sealing groove 18, in conjunction with the slots 15, can maintain the sealing effect of the water outlet 14 during the rotation of the fan-shaped block 17, preventing water waste.
[0022] As a technical optimization of this utility model, an arc-shaped rod 23 is fixedly connected to one side of the sector block 17, and an arc-shaped sleeve 24 is fixedly connected to the top of the inner wall of the fixing box 16. The top of the arc-shaped rod 23 is slidably connected to the bottom of the arc-shaped sleeve 24. A spring is provided inside the arc-shaped sleeve 24, and the two ends of the spring abut against the top of the arc-shaped rod 23 and the inner wall of the top of the arc-shaped sleeve 24, respectively. The force exerted by the spring on the arc-shaped rod 23 keeps the sector block 17 connected to the first inlet 19 and the outlet 14 even when it is not subjected to the force of the wire rope 25. The arc-shaped rod 23 and the arc-shaped sleeve 24 themselves also facilitate the rotational guidance of the sector block 17.
[0023] As a technical optimization of this utility model, the two ends of the same steel wire rope 25 are fixedly connected to both sides of the fan-shaped block 17. The steel wire rope 25 passes through the top and side wall of the fixed box 16 through guide blocks. By manually pulling the two sides of the steel wire rope 25, the fan-shaped block 17 is rotated towards or away from the spray head 21, thereby realizing the switching between the spray head 21 and the sprinkler head 22. The construction personnel can judge whether the fan-shaped block 17 has rotated to the correct position by the self-limiting effect of the arc rod 23 and the arc sleeve 24. After it has rotated to the correct position, the steel wire rope 25 is fixed to the outside, so that the fan-shaped block 17 is externally fixed, ensuring the normal use of the spray head 21 or the sprinkler head 22.
[0024] In use, construction workers first install dust suppression spraying devices on both sides of the road. The base 1 is placed on the foundation on both sides of the road. The base 1 is fixed to the foundation using bolts connected to two bolt holes 3. Construction workers then lift the column 6, causing it to rotate in the mounting groove 4 via the rotating block 5, until the column 6 is vertical. At this point, the rotating handle 12 is moved, causing it to engage in the through groove at the top of the first fixed seat 7. A locking rod 8 is then inserted into the through hole, and simultaneously, the locking rod 8 is inserted into the locking hole 13. Then... A limiting screw is inserted into the limiting hole 9 to prevent the locking rod 8 from falling off. The water pipe of the external water pump is connected to the water pipe connector 10. The construction personnel manually pull the steel wire rope 25 on one side of the top of the fixing box 16 to drive the fan-shaped block 17 to rotate towards the spray head 21. At the same time, the reaction force of the spring also pushes the arc rod 23, causing the arc rod 23 to slide to the bottom of the arc sleeve 24. At this time, the top of the water outlet 14 is connected to the first inlet 19. The external water pump is turned on, and clean water can flow into the spray head 21 through the first inlet 19 to form a spray to spray and suppress dust.
[0025] When large machinery needs to pass over the road, the locking rod 8 can be removed, and the column 6 can be rotated away from the road. When it is rotated to an angle that does not affect the movement of the large machinery, the above operation can be repeated to fix the column 6 again, or the column 6 can be laid down directly.
[0026] When a layer of road construction is completed or the entire construction is finished, and water retention work is required, rotate the column 6 towards the side closer to the road. Stop rotating it when the sprinkler head 22 is tilted towards the road surface. Repeat the above operation to fix the column 6. At this time, the construction personnel manually pull the steel wire rope 25 on one side of the fixing box 16 to drive the fan-shaped block 17 away from the spray head 21. The arc-shaped sealing groove 18 slides along the slot 15, and the arc-shaped rod 23 slides along the arc-shaped sleeve 24 to the top of the arc-shaped sleeve 24 and compresses the spring. At this time, the top of the water outlet 14 is connected to the second inlet 20. Turn on the external water pump, and clean water can flow into the sprinkler head 22 through the second inlet 20 to form a water flow to spray water on the road surface for water retention treatment.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
