Description

Technical Field

[0001] This utility model relates to a dust suppression device, specifically a dust suppression device for road joint cutting, belonging to the technical field of road construction equipment. Background Technology

[0002] During concrete construction, to prevent deformation stress from occurring in cement concrete pavement due to temperature changes, and to prevent cracks and warping caused by stress concentration, joints are cut inside the concrete pavement. This releases the stress generated by high temperatures, reduces cracks caused by shrinkage or expansion, and extends the service life of the concrete pavement. Cutting joints can reduce pavement damage and extend its service life. After cutting joints, grouting is also required to seal the gaps, which can effectively prevent rainwater from seeping into the roadbed, avoid roadbed collapse and erosion, and improve the efficiency of road use.

[0003] Most existing road cutting devices use saw blades for cutting. When the saw blade cuts the road surface, it causes the concrete pavement material to break and separate. Due to the high hardness of concrete, a large amount of dust is generated during the cutting process. Currently, most methods rely on water spraying to degrade the dust. However, the high-speed rotation of the saw blade may throw undegraded dust backward, expanding the dust distribution area. At the same time, the dust poses a health hazard to construction workers. Therefore, we provide a dust suppression device for road cutting to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a dust suppression device for road cutting joints, so as to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust suppression device for road cutting, comprising a saw blade and a base plate. A base is connected to the upper surface of the base plate, and a rotating shaft is rotatably connected to the inner wall of the base. A power mechanism is provided outside the rotating shaft. The interior of the saw blade is connected to one end of the rotating shaft located outside the base plate. A dust cover is connected to the upper surface of the base plate and is located outside the saw blade. A flow-collecting hood is connected to one side of the dust cover, and a conveying pipe is connected to one side of the flow-collecting hood. A first water tank is connected to the upper surface of the base plate, and a flow-collecting barrel is also connected to the upper surface of the first water tank. An exhaust fan is installed inside the flow-collecting barrel, and an air inlet pipe is installed below the flow-collecting barrel and is located inside the first water tank. An exhaust pipe is connected to the upper surface of the first water tank, and the other end of the conveying pipe is connected to one side of the flow-collecting barrel.

[0006] Preferably, the lower surface of the base plate is connected to four casters, and the four casters are located at the four corners of the base plate. Two of the casters have height adjustment function, and the upper surface of the base plate is connected to a handle.

[0007] Preferably, the power mechanism includes a motor, which is mounted above the base plate, and the output shaft of the motor is connected to a pulley.

[0008] Preferably, a second pulley is connected to the outer surface of the rotating shaft, and a transmission belt is sleeved on the outside of the second pulley and the first pulley, and the first pulley and the second pulley are connected by the transmission belt.

[0009] Preferably, a support base is connected to one side of the dust cover, a diversion pipe is connected to the inner wall of the support base, a nozzle is connected to the bottom end of the diversion pipe and the nozzle is located outside the saw blade, and a water supply pipe is connected to the outer surface of the diversion pipe.

[0010] Preferably, a second water tank is connected to the upper surface of the base plate, a water pump is installed inside the second water tank, and the other end of the water supply pipe is connected to the output end of the water pump.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The dust suppression device for road cutting in this application works in conjunction with a dust collector, an exhaust fan, and a first water tank. The dust collector collects the dust thrown backward by the saw blade, and the exhaust fan provides power for the air to flow into the first water tank. The air collected by the dust collector is discharged into the dust collector barrel through a delivery pipe. The dust collector barrel then discharges the air into the first water tank through a collection pipe. The water in the first water tank absorbs the dust mixed in with the air, and the purified air is discharged through an exhaust pipe, reducing the spread of dust to the outside and improving the working environment for workers.

[0014] 2. The dust suppression device for road cutting in this application works by coordinating nozzles, water supply pipes, and a water pump. The water pump provides power for the flow of water, which is then delivered to a distribution pipe through the supply pipe. The distribution pipe distributes the water to the nozzles, which then compress the water to form a mist. This mist is then evenly sprayed onto the band saw blade, degrading the dust on the blade. The water sprayed from the nozzles also cools the saw blade, preventing it from overheating and extending its service life. Attached Figure Description

The dust collected by the concentrator 7 is transported to the inside of the first water tank 9 through the conveying pipe 8 using the exhaust fan 12 as a power source. The concentrator 11 discharges the dust-containing air into the first water tank 9 through the air inlet pipe 13. The dust in the air is absorbed by the water source inside the first water tank 9, and the air purified by the water source is discharged from the first water tank 9 through the exhaust pipe 10.

[0025] Four casters 14 are connected to the lower surface of the base plate 2, and the four casters 14 are located at the four corners of the base plate 2. Two of the casters 14 have the function of adjusting the height. A handle 15 is connected to the upper surface of the base plate 2. The casters 14 are used to move the cutting machine. The front caster 14 has the function of adjusting the height. By rotating the internal screw, the height position of the lower caster 14 is changed.

After the exhaust fan 12 rotates, it drives the air to flow. At the same time, the air carries away the dust thrown behind the saw blade 1. Then the flowing air is collected by the concentrator 7. The air collected by the concentrator 7 enters the concentrator tank 11 through the delivery pipe 8. Then the air passes through the concentrator tank 11 and enters the air inlet pipe 13. The air is discharged into the first water tank 9 through the air inlet pipe 13. The water in the first water tank 9 absorbs the dust mixed in the air. Then the air is discharged from the first water tank 9 through the exhaust pipe 10.
