Description

Technical Field

[0001] The utility model relates to the technical field of road surface demolition and crushing, in particular to a noise reduction, dust prevention device for concrete road surface demolition and crushing. Background Technique

[0002] During the construction of cast-in-place piles, it involves the backfill part under the original road surface. There are a large number of concrete blocks in the backfill soil of this part. Some of these concretes will directly affect the normal operation of the rotary drilling rig due to their large volume. Therefore, it is necessary to break and clean the large-volume concrete blocks before continuing the operation. When demolishing a small area of the road surface, usually workers hold a pneumatic breaker to operate. The pneumatic breaker is usually held by the worker at the body part, and then the breaking head is installed at the output end of the breaker. Through the high-speed movement of the piston or cylinder in the driving system of the breaker, the breaking head is driven to impact the road surface at an extremely high speed, generating a strong impact force to crush the road surface.

[0003] When the existing pneumatic breaker crushes the ground, the breaking head is directly exposed to the outside. When impacting, it will generate a large amount of noise, causing small-area noise pollution and also damaging the hearing of workers. Moreover, the dust in the gaps of the broken road surface will diffuse into the air along with the vibration generated by the impact. The dust is easily inhaled by workers and will also cause dust pollution, making it inconvenient to deal with the noise and dust during operation. Content of the Utility Model

[0004] The purpose of the utility model is to provide a noise reduction, dust prevention device for concrete road surface demolition and crushing to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Please refer to Figures 1-5, in the embodiment of the present utility model, a noise reduction and dust prevention device for concrete pavement demolition and crushing includes a separation component 1. The separation component 1 includes a hollow ring 101. Two annular rubber sheets 104 are fixedly installed inside the hollow ring 101. A plurality of arc-shaped rubber sheets 102 are fixedly installed on the lower surface of the hollow ring 101. A gasket 103 is fixedly installed at the lower ends of the plurality of arc-shaped rubber sheets 102. A connecting pipe 106 is fixedly embedded on the outer surface of the hollow ring 101. A sedimentation component 2 is fixedly installed on the outer surface of the connecting pipe 106. A fixing component 3 is fixedly installed on the upper surface of the hollow ring 101.

[0035] Specifically, the separation component 1 is installed at the lower outer side of the crushing head of the pneumatic breaker through the fixing component 3. The separation component 1 blocks the transmission of sound and collects dust at the same time, so that the collected dust is absorbed and settled by the water mist ejected by the sedimentation component 2.

[0036] Embodiment 1

[0037] As Figure 1 and Figure 5 shown, in this embodiment, a plurality of air inlet grooves 105 are equally angled on the outer surface of the hollow ring 101 and on one side surface of the annular rubber sheet 104. A collecting pipe 107 is fixedly communicated with the outer surface of the connecting pipe 106. An exhaust hood 108 is fixedly installed at one end of the collecting pipe 107. A dust removal fan 109 is fixedly installed inside the exhaust hood 108. The sedimentation component 2 includes: a water tank 201 is fixedly installed on the outer surface of the connecting pipe 106 through a bracket. A water pump 202 is fixedly installed at the upper end of the water tank 201. An atomizing nozzle 203 is fixedly installed at one end of the exhaust hood 108 and is communicated with the water outlet end of the water pump 202 through a hose.

[0038] In this embodiment, the gasket 103 fits the ground, so that the hollow ring 101 covers the crushing area. The plurality of arc-shaped rubber sheets 102 can be bent, so that the hollow ring 101 moves up and down to adapt to the up and down movement of the crushing head. At the same time, the space between the plurality of arc-shaped rubber sheets 102 and their bodies cooperate to block the transmission of sound. Then the dust removal fan 109 operates. When the crushing head moves up and down, the gasket 103 cannot completely fit the road surface. The air entering through the gap carries the floating dust and passes through the plurality of air inlet grooves 105 into the connecting pipe 106. The positions and angles of the plurality of air inlet grooves 105 are different, so that the air can flow inside the hollow ring 101, and the transmission of sound is further reduced through the air flow. Thus, the road surface crushing area is isolated from the outside, and the noise is reduced, reducing the noise transmitted from the operation area to the outside, reducing noise pollution, and reducing the damage to the hearing of workers by the noise. The water pump 202 operates, and the water in the water tank 201 is sprayed out in a mist through the atomizing nozzle 203 to absorb and settle the discharged dust. At the same time, the water mist settles on the crushed road surface to moisten the crushed road surface and reduce the dust floating out of the road surface gaps, improving the dust prevention effect.

[0039] As Figures 2-4 shown, in this embodiment, the fixing component 3 includes: a plurality of support rods 301 fixedly installed on the upper surface of the hollow ring 101 at equal angles, a circular ring 303 fixedly installed at the upper ends of the plurality of support rods 301, a bottom plate 304 fixedly installed on the upper surface of the circular ring 303, and a rotating plate 306 rotatably connected above the bottom plate 304; a rubber sealing sheet 302 is fixedly connected between two adjacent support rods 301, a sliding groove 305 is formed on the upper surface of the bottom plate 304, a slider 308 is slidably connected inside the sliding groove 305, a T-shaped clamping rod 309 is fixedly installed on one side surface of the slider 308, and the T-shaped clamping rod 309 slidably penetrates the inner surface of the bottom plate 304; an arc-shaped groove 307 is formed on the upper surface of the rotating plate 306, the upper end of the slider 308 penetrates the arc-shaped groove 307 at the corresponding position and is slidably connected with the arc-shaped groove 307.

[0040] During specific implementation, insert the crushing head into the inside of the circular ring 303, rotate the rotating plate 306, the arc-shaped groove 307 rotates, push the slider 308 to slide inside the sliding groove 305, so that a plurality of T-shaped clamping rods 309 move towards the middle to clamp the crushing head, so that the separating component 1 can move simultaneously with the crushing head.

[0041] Embodiment Two

[0042] On the basis of Embodiment One, in order to make up for the problem that the firmness of the T-shaped clamping rod 309 is poor.
