Description

Technical Field

[0001] The utility model relates to the technical field of highway construction equipment, in particular to a highway construction dust reduction device. Background Art

[0002] The highway construction dust reduction device is designed specifically to solve the dust problem generated during highway construction. During highway construction, operations such as excavation and transportation generate a large amount of dust, which not only affects air quality but also threatens the health of construction workers and surrounding residents. This dust may also pollute crops, water bodies, and soil. The dust reduction device effectively adsorbs and reduces dust particles in the air by spraying water mist, significantly reducing construction dust, ensuring the construction environment, improving construction quality, and protecting the surrounding ecology and the health of residents at the same time.

[0003] In the prior art, a Chinese patent document with the publication number CN213328865U proposed a sprinkler dust reduction device for highway construction, including a mounting plate. The left and right lower ends of the mounting plate are respectively fixedly installed with a first support plate and a second support plate. The lower right side of the right end of the second support plate is fixedly installed with a cleaning device. The left end of the cleaning device penetrates through the lower part of the second support plate and is fixedly connected to the lower part of the right end of the first support plate. Although the dust reduction effect is improved compared with the traditional fixed nozzle spraying; the cleaning brush is driven by a first motor to clean the ground, making the device powerful and meeting the use requirements of highway construction. However, what is the same as the traditional method is that: driving the cleaning brush by a motor can indeed clean the highway surface, but a large amount of dust-reducing dust and liquid-carrying dust will adhere to the surface of the cleaning brush. When the dust and liquid on the surface of the cleaning brush evaporate, the dust will fall to the ground, and when a vehicle passes by, the dust can easily float in the air again, resulting in the need to frequently carry out dust reduction work on the highway surface.

[0004] Furthermore, we disclose a highway construction dust reduction device to meet the actual needs of the prior art that the dust cleaning effect of the dust reduction device is not good and the highway surface needs to be frequently dusted. Content of the Utility Model

A second one-way valve is connected to the lower end of the water storage sleeve, and the second one-way valve is used to drain the water storage sleeve. When the piston inside the sealing sleeve moves upward, the liquid inside the water storage tank will enter the water storage sleeve through the water inlet pipe. When the piston moves downward through the piston rod, the liquid inside the water storage sleeve will be discharged to the drain pipe through the second one-way valve and discharged by the water head. The liquid discharged from the water head will fall onto the sponge, so that the dust on the sponge remains moist, ensuring that the dust is not easy to float and run out of the collection box, thereby reducing the frequency of subsequent dust reduction work.

[0024] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with specific embodiments.

[0025] Such as Figures 1 to 5As shown in the figure, a dust reduction device for road construction includes a wheelbarrow 9. A cleaning brush wheel 11 for cleaning the road surface is rotatably connected to the middle of the wheelbarrow 9. One side of the upper end of the wheelbarrow 9 is fixedly connected with a water storage tank 1. One side of the upper end of the wheelbarrow 9 far away from the water storage tank 1 is fixedly connected with an equipment box 8. A spraying assembly for dust reduction in the air is arranged in the middle of the upper end of the equipment box 8. One side of the lower end of the water storage tank 1 is fixedly connected with a collection box 18. A cleaning assembly for cleaning the bristles on the cleaning brush wheel 11 is arranged on one side of the upper part of the inside of the collection box 18. The cleaning assembly includes a plurality of connecting plates 23. Fixed plates 24 are arranged between the plurality of connecting plates 23. A storage box 17 for collecting the dust cleaned by the cleaning assembly is slidably connected to the inner bottom of the collection box 18. A sponge 22 is arranged at the lower end of the inside of the storage box 17. A wetting assembly for preventing the dust inside the storage box 17 from floating is arranged at the upper end of the collection box 18. The dust reduction device is provided with a cleaning assembly, which is used to clean the bristles on the cleaning brush wheel 11, so that the dust and liquid on the bristles can be cleaned in time during the cleaning process, reducing the possibility of the dust falling back to the ground after the liquid evaporates. The cleaned dust and liquid are collected in the storage box 17. The sponge 22 arranged inside the storage box 17 can absorb these liquids, further reducing the flying of dust. The setting of the wetting assembly can keep the sponge 22 inside the storage box 17 moist, ensuring that the dust is not likely to float, thereby reducing the frequency of subsequent dust reduction work.

[0026] As an implementation method in this embodiment, as Figures 2 to 5As shown, a plurality of connecting plates 23 are evenly spaced and fixedly connected to the upper end of one side of the collecting box 18 close to the cleaning brush wheel 11, the upper end of the fixed plate 24 is fixedly connected to the collecting box 18, and the lower ends of the plurality of connecting plates 23 are rotatably connected with a rotating plate 26, and the middle parts of the end surfaces of both sides of the connecting plates 23 are fixedly connected with a baffle plate 27, and one side of the upper end of the baffle plate 27 is fixedly connected with a telescopic spring 28, and the upper end of the telescopic spring 28 is fixedly connected to the side of the rotating plate 26 away from the rotatable connection with the connecting plate 23, and the connecting plate 23 and the fixed plate 24 are both L-shaped in design, and the fixed plate 24 is made of hard rubber material. A servo motor 10 is arranged in the inner middle part of the equipment box 8, and the output end of the servo motor 10 is connected to one end of the cleaning brush wheel 11 through a belt. The cleaning brush wheel 11 is driven by the servo motor 10 to rotate clockwise. When the cleaning brush wheel 11 rotates, the bristles are located between the connecting plates 23. The bristles first contact the rotating plate 26, driving the rotating plate 26 to rotate counterclockwise. Since the lower end of the rotating plate 26 is connected with a telescopic spring 28, when the rotating plate 26 rotates to a certain position, the bristles will deform and break away from the contact with the rotating plate 26. After breaking away from the contact, the bristles will collide with the fixed plate 24, causing the collision to cause the dust on the bristles to fall off. Since the connecting plate 23 is L-shaped, the fallen dust will slide through the connecting plate 23 to the sponge 22 in the storage box 17. The fixed plate 24 is made of hard rubber material, which reduces the damage to the bristles when a collision occurs and increases the service life of the bristles.

[0027] As an implementation method in this embodiment, Figure 3As shown in the figure, the wetting component includes a water storage sleeve 19 fixedly connected to the middle of the upper end of the collection box 18 and a sealing sleeve 13 fixedly connected to the upper end of the inner wall of the water storage tank 1.

The upper end of the piston rod 12 passes through the water storage tank 1 and is slidably connected to the water storage tank 1. The middle of the lower end of the water storage sleeve 19 is fixedly connected with a second one-way valve 25. The lower end of the second one-way valve 25 extends into the collection box 18 and is fixedly connected with a drain pipe 20. The lower end of the drain pipe 20 is fixedly connected with a plurality of shower heads 21 at equal intervals. The lower end of one side of the water storage sleeve 19 is fixedly connected with a water inlet pipe 15. The lower end of the water inlet pipe 15 is located at the lower end of the water storage tank 1 and is fixedly connected with a first one-way valve 16. When the dust reduction device is in use, the user manually pulls the piston rod 12 to make the piston slide inside the sealing sleeve 13. The sealing sleeve 13 is connected and communicated with the water storage sleeve 19. A water inlet pipe 15 is connected to the lower end of the outer wall of the water storage sleeve 19. The lower end of the water inlet pipe 15 is connected with a first one-way valve 16. The first one-way valve 16 is used to supply water to the inside of the water storage sleeve 19. A second one-way valve 25 is connected to the lower end of the water storage sleeve 19. The second one-way valve 25 is used for the drainage work of the water storage sleeve 19. When the piston inside the sealing sleeve 13 moves upward, the liquid inside the water storage tank 1 will enter the water storage sleeve 19 through the water inlet pipe 15. When the piston moves downward through the piston rod 12, the liquid inside the water storage sleeve 19 will be discharged to the drain pipe 20 through the second one-way valve 25 and discharged by the shower heads 21. The liquid discharged by the shower heads 21 will fall onto the sponge 22, making the dust on the sponge 22 keep wet, ensuring that the dust is not easy to float and run out of the collection box 18, thereby reducing the frequency of subsequent dust reduction work.

[0028] As an implementation method in this embodiment, as Figures 1 to 3 shown, the spraying component includes a fixed seat 7 fixedly connected to the equipment box 8. The upper end of the fixed seat 7 is fixedly connected with a fixed frame 4. A lead screw 6 is rotatably connected inside the fixed frame 4. A water spraying frame 5 is drivingly connected to the outside of the lead screw 6. The water spraying frame 5 is of a hollow design and is fixedly connected with a plurality of nozzles at equal intervals on the outer wall away from the water storage tank 1. A motor for driving the lead screw 6 to rotate is arranged inside the fixed seat 7. A water pump 2 is arranged on one side of the upper end of the water storage tank 1. The input end of the water pump 2 is fixedly connected with an input pipe. The lower end of the input pipe is located at the lower end of the inside of the water storage tank 1. The output end of the water pump 2 is fixedly connected with a hose 3. One end of the hose 3 away from the water pump 2 is fixedly connected and communicated with the water spraying frame 5. When the dust reduction device is in use, the motor drives the lead screw 6 to rotate, so that the nozzles on the water spraying frame 5 are placed at a suitable dust reduction height. The water pump 2 is used for water supply. The liquid in the water storage tank 1 enters the water pump 2 through the input pipe. The liquid in the water pump 2 enters the water spraying frame 5 through the hose 3. The liquid in the water spraying frame 5 is sprayed out through the nozzles to complete the dust reduction work.

[0029] The technical solution provided by the present invention is driven by a servo motor to rotate clockwise. When the cleaning brush wheel rotates, the bristles are located between the connecting plates. The bristles first contact the rotating plate, driving the rotating plate to rotate counterclockwise. Since the lower end of the rotating plate is connected to a telescopic spring, when the rotating plate rotates to a certain position, the bristles will be deformed and disengaged from the rotating plate. After disengaging from the contact, the bristles will collide with the fixed plate, causing the collision to cause dust on the bristles to fall off. Since the connecting plate is designed in an L-shape, the fallen dust will slide through the connecting plate and fall onto the sponge in the storage box. The fixed plate is made of hard rubber material, which reduces damage to the bristles when a collision occurs and increases the service life of the bristles. Through this structural design, the dust on the bristles can be cleaned in time during the cleaning process, reducing the possibility of dust falling back to the ground after the liquid evaporates.

[0030] By manually pulling the piston rod, the piston slides inside the sealing sleeve, and the sealing sleeve is connected and communicated with the water storage sleeve. A water inlet pipe is connected to the lower end of one side of the outer wall of the water storage sleeve, and a first one-way valve is connected to the lower end of the water inlet pipe. The first one-way valve is used to allow water to enter the water storage sleeve. A second one-way valve is connected to the lower end of the water storage sleeve, and the second one-way valve is used to drain the water storage sleeve. When the piston inside the sealing sleeve moves upward, the liquid inside the water storage tank will enter the water storage sleeve through the water inlet pipe. When the piston moves downward through the piston rod, the liquid inside the water storage sleeve will be discharged to the drain pipe through the second one-way valve and discharged by the water head. The liquid discharged from the water head will fall onto the sponge, so that the dust on the sponge remains moist, ensuring that the dust is not easy to float and run out of the collection box, thereby reducing the frequency of subsequent dust reduction work.

[0031] The utility model is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
