Description

Technical Field

[0001] This invention relates to the field of environmental protection and dust suppression technology in road construction, specifically to an environmental protection and dust suppression device for road construction. Background Technology

[0002] Road construction generates significant amounts of dust, severely impacting the environment of the construction area and the city, which is detrimental to environmental protection. To address this issue, existing technologies typically employ large-scale dust suppression devices, such as perimeter spray systems, mist cannons, water trucks, and high-pole spray dust suppression systems. Perimeter spray systems reduce dust by installing spray facilities around the construction site and using water spray. Misty cannons are devices that achieve dust suppression through high-pressure water mist, suitable for large-scale dust control needs. Water trucks use mobile water spraying to cover roads, suitable for dust suppression on urban main roads. High-pole spray dust suppression systems reduce dust by spraying water mist from high-pole equipment. Each of these methods has its advantages and disadvantages; the key issue is that dust control only prevents dust accumulation. When faced with high temperatures, strong winds, or other unfavorable conditions, dust re-emerges, failing to address the root cause or turn waste into resources.

[0003] Moreover, these devices are mainly suitable for large-scale and long-term construction dust suppression, but they are often unsuitable for some refined, small-scale or auxiliary operations.

[0004] Especially when breaking up concrete pavements, handheld crushers are often used in areas where large crushers are inconvenient to operate. However, handheld crushers present challenges in dust control. The operating points of handheld crushers are relatively concentrated, and each operation is relatively short, thus failing to effectively utilize the dust suppression capabilities of larger machinery. The generated dust is difficult to control at its source, and if workers do not wear dust protection equipment, they are prone to inhaling dust, causing harm to their health. Wearing dust protection equipment significantly impacts the convenience of construction and increases road construction costs. Summary of the Invention

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 9 As shown, the present invention provides an environmentally friendly dust suppression device for road construction, including a protective device 1. A dust suction device 2 is installed on the protective device 1, which can remove dust generated inside the protective device 1. Specifically, the protective device 1 includes an upper protective plate 11 and side protective plates 12 located on both sides. The inner sides of the upper protective plate 11 and the side protective plates 12 form a working space, and multiple casters 13 are respectively installed at the bottom of the side protective plates.

[0021] Construction workers can work within the work space. The bottom of the side guard plate 12 is equipped with multiple casters 13, which facilitates the movement of the guard device 1. The guard device 1 is moved to the top of the cement road surface that needs to be broken, and the construction workers can work inside the guard device 1. The workers hold the crusher 27 and break the cement road surface inside the guard device 1. After the cement road surface inside the guard device 1 is broken, the guard device 1 is moved to the next cement road surface that needs to be broken.

[0022] The protective device 1 can protect construction workers, provide shade and rain protection, offer shade in summer and wind protection in winter, and allow workers to work and rest comfortably inside the protective device 1.

[0023] Specifically, the dust collection device 2 includes a dust collection box 21 and a dust filter box 22 fixedly connected to the upper protective plate 11. The dust collection box 21 is equipped with a motor 211 and a fan blade 212. The dust filter box 22 is equipped with a filter screen 221. A connecting pipe 25 connects the dust collection box 21 and the dust filter box 22. The other side of the dust filter box 22 is connected to a dust collection pipe 23 located in the protective device 1. The other side of the dust collection box 21 is connected to an exhaust pipe 24 located in the protective device 1.

[0024] A sealing dust collection device 26 is connected to the dust collection pipe 23, a cooling box 52 is connected to the exhaust pipe 24, a dust suppressant storage device 3 is installed on the connecting pipe 25, a mixing and stirring device is installed inside the dust filter box 22, and a spraying device 4 is connected to the dust filter box 22.

[0025] Specifically, the motor 211 drives the fan blade 212 to rotate, which in turn causes the suction pipe 23 to generate suction, which sucks away the cement dust generated by the crusher 27 on the crushed cement road surface. The cement dust enters the dust filter box 22 through the suction pipe 23 and is blocked in the dust filter box 22 by the filter screen 221. The exhaust pipe 24 is used for exhaust.

[0026] The sealed dust collection device 26 includes a sealing sleeve 261, a fixing hole 262 is provided inside the sealing sleeve 261, a buffer plate 263 is provided at the bottom of the sealing sleeve 261, a buffer groove 264 matching the buffer plate 263 is provided at the bottom end of the sealing sleeve 261, a spring 265 is fixedly connected between the bottom wall of the buffer groove 264 and the upper end face of the buffer plate 263, a fixing groove 266 is provided on both sides of the fixing hole 262 inside the sealing sleeve 261, an electric push rod 267 is provided in the fixing groove 266, and a clamping plate 268 is provided on the electric push rod 267.

[0027] Specifically, when operators use the crusher 27 to break up the cement pavement, the sealed dust collection device 26 can be removed. The crusher 27 is then placed inside the sealing sleeve 261 through the fixing hole 262. The electric push rod 267 moves the clamping plate 268, clamping it onto the crusher 27 and fixing the sealing sleeve 261 to the crusher 27. A sealing gasket is provided at the bottom of the buffer plate 263. When the crusher 27 is pressed down, the buffer plate 263 acts as a buffer, ensuring that the bottom surface of the buffer plate 263 remains in contact with the cement pavement. The sealing sleeve 261 is made of transparent material, facilitating observation of the crushing process. Dust generated by the crusher 27 during pavement breaking is trapped inside the sealing sleeve 261 and will not leak out, preventing operators from inhaling the dust. The dust collection pipe 23 removes the dust from the sealing sleeve 261, and the cement dust is sucked into the dust filter box 22 for storage.

[0028] Meanwhile, the sealing sleeve 261 can be horizontally fixed on the fixing rod 121. The fixing rod 121 is inserted into the fixing hole 262. The clamping plate 268 is moved and clamped on the fixing rod 121 by the electric push rod 267, thereby fixing the sealing sleeve 261. The fixing rod 121 is set vertically, so the height of the sealing sleeve 261 can be adjusted.

[0029] Timber is used in road construction. When pouring regularly shaped, non-horizontal concrete components such as curbs, sidewalk slabs, drainage ditches, manhole covers, wing walls of small bridges, and guardrail foundations, wooden planks, usually plywood and square timber, are used to create molds to fix the concrete shape until it hardens. It is also used to create simple pit wall supports when excavating trenches and foundation pits; as a frame when building temporary sheds, signboard frames, and safety shelters; and as blocks or wedges when installing equipment. In soft soil foundations or muddy areas, logs or thick planks are laid as temporary access roads for heavy equipment to prevent it from sinking. These processes require the use of wood cutters, which produce sawdust during the cutting process.

[0030] The protective device 1 can be moved to the wood cutting machine, which is located inside the protective device 1. By adjusting the position of the sealed dust collection device 26, the sealed dust collection device 26 is positioned so that it faces the cutting edge between the cutting blade and the wood. The wood chips produced during cutting are sucked away through the sealed dust collection device 26 and the suction pipe 23, and then drawn into the dust filter box 22. (See details...) Figure 9 As shown.

[0031] The dust filter box 22 is equipped with a mixing and stirring device, which includes a stirring rod 222 located inside the dust filter box 22 and a drive motor fixedly connected to the upper end face of the dust filter box 22 and connected to the stirring rod 222. The drive motor drives the stirring rod 222 to rotate. The dust suppressant storage device 3 includes a storage box 31, which contains dust suppressant. A discharge pipe 32 is connected between the storage box 31 and the dust filter box 22. A control valve is installed in the discharge pipe 32. A support frame 33 is fixedly connected between the storage box 31 and the upper protective plate 11. The amount of dust suppressant discharged into the dust filter box 22 can be controlled by the control valve.

[0032] A spraying device 4 is provided on the dust filter box 22. The spraying device 4 includes a delivery pump 41 and a spray box 44. A first delivery pipe 42 is connected between the delivery pump 41 and the dust filter box 22, and a second delivery pipe 43 is connected between the delivery pump 41 and the spray box 44. Multiple nozzles 45 are provided on the spray box 44.

[0033] Specifically, the dust filter box 22 can block cement dust or wood chips, allowing them to be stored inside. The dust suppressant in the storage box 31 is water, which is then transported to the dust filter box 22 through the discharge pipe 32. The water, cement dust, or wood chips are mixed and stirred in the dust filter box 22 by the stirring rod 222 to form a dust suppressant slurry with viscosity and coagulation ability. The dust suppressant slurry is transported to the spray box 44 through the first conveying pipe 42, the conveying pump 41, and the second conveying pipe 43, and then sprayed out through multiple nozzles 45.

[0034] After the cement pavement is broken up, cement blocks are formed, which need to be cleaned up. The cleaning process can easily generate dust. When the protective device 1 is pushed to the next breaking point, it can move the spray box 44. During the movement, the spray box 44 continuously sprays dust suppressant onto the broken cement pavement. After the slurry dries, it forms a protective shell that can prevent dust from being blown away by the wind.

[0035] Meanwhile, other operations can also be carried out within the protective device 1. During the roadbed and foundation treatment stage, it is necessary to manually dig test pits or trenches, that is, to excavate manually using shovels, picks, etc., to explore underground pipelines or geological conditions. Soil is very prone to generating dust after it dries. By spraying dust suppression slurry onto the soil, the slurry forms a protective shell after drying, which can prevent dust from being blown away by the wind.

[0036] The second delivery pipe 43 and the suction pipe 23 are both flexible hoses. A second storage box 431 matching the second delivery pipe 43 is fixedly connected to the upper protective plate 11. A first storage box 231 matching the suction pipe 23 is fixedly connected to the side protective plate 12. The second delivery pipe 43 passes through the second storage box 431, and the suction pipe 23 passes through the first storage box 231. Storage rods are rotatably connected inside the second storage box 431 and the first storage box 231, respectively.

[0037] When not in use, the spray box 44 is fixed inside the upper fixing plate 46. When it is necessary to use the spray box 44 to spray dust suppression slurry, it is fixed inside the lower fixing plate 46. The second conveying pipe 43 can be pulled out from the second storage box 431. The spray box 44 is close to the broken cement road surface or the excavated soil, which increases the spraying effect. When the sealed dust collection device 26 is fixed to the crusher 27, the dust collection pipe 23 can be pulled out from the first storage box 231.

[0038] A cooling box 52 located in the work space is connected to the exhaust pipe 24. The cooling box 52 has multiple air outlets 521. A battery 51 is fixedly connected to the inside of the side guard plate 12. The battery 51 is located below the cooling box 52 and is equipped with a charging socket and a socket.

[0039] Specifically, the battery 51 is located inside the protective device 1, and the battery 51 can be easily charged through the charging socket. When the electric crushing tool can be electrically connected to the battery 51, there is no need to connect other power supply devices. The connecting cables on the crusher 27 will not be exposed, and it can still crush cement pavement when it rains.

[0040] The connecting pipe 25 is bent and located inside the storage box 31. Water can be used to cool the gas generated by the dust collection box 21. The connecting pipe 25 located inside the storage box 31 is made of a material with good heat transfer, which facilitates cooling. The cooled gas is discharged through the cooling box 52, which can dissipate heat from the battery 51. At the same time, it can accelerate the air flow in the protective device 1 and reduce the temperature inside the protective device 1. In summer, the temperature inside the protective device 1 is low, providing a comfortable working environment for the operators.

[0041] A lighting lamp 54 is fixedly connected to the inner side of the upper protective plate 11, which can provide illumination and facilitate nighttime operations.

[0042] A control board 53 is provided on the inner side of the side protection plate 12. The motor 211, stirring rod 222, control valve and lighting 54 are all connected to the control board 53 by signal and are all electrically connected to the battery 51, which can control the operation.

[0043] When using, refer to Figures 1-9As shown, workers can break up the cement pavement inside the protective device 1. The sealing sleeve 261 can be fixed to the crusher 27. The cement dust generated by the crusher 27 during crushing is blocked inside the sealing sleeve 261, preventing dust from leaking out. The cement dust inside the sealing sleeve 261 is sucked into the dust filter box 22 through the suction pipe 23. Water in the storage tank 31 can be transported to the dust filter box 22 and mixed with the cement dust in the dust filter box 22 to form a dust suppression slurry. After the cement pavement inside the protective device 1 is broken up, when the protective device 1 is moved to the next breaking point, the spray box 44 can be moved during the movement of the protective device 1. The dust suppression slurry is sprayed onto the broken cement blocks through the nozzle 45. After the slurry dries, it forms a protective shell to prevent dust from being blown away by the wind.

[0044] Compared with the prior art, the beneficial effects of the present invention are: it can control dust at the source, construction workers do not need to wear dust protection equipment, are less likely to inhale dust, increase the convenience of construction, reduce the cost of road construction, and is especially convenient for handling dust generated by continuous small-scale road construction operations.

[0045] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
