Description

Technical Field

[0001] The utility model relates to the technical field of dust removal for synchronous sealing of asphalt macadam, in particular to a dust removal device for synchronous sealing of asphalt macadam which can prevent water from splashing. Background Art

[0002] Synchronous gravel seal vehicle is a road and bridge construction vehicle. It refers to the use of synchronous gravel seal vehicle to spray asphalt mixture and spread aggregate at the same time, so that there is the most complete contact between the asphalt mixture and the aggregate to achieve the maximum adhesion between them. It is mainly used for the construction of lower or upper seal layers of highway pavements, the construction of wearing layers on new and old pavements, the layer paving method of asphalt pavements, and the separate spreading of asphalt gravel under special circumstances. Compared with ordinary gravel seal, asphalt gravel synchronous seal effectively shortens the time interval between spraying binder and spreading aggregate, so that aggregate particles can be better embedded in the binder to obtain more covering area and improve the quality of road paving.

[0003] When an asphalt gravel synchronous sealing vehicle is paving a road, a large amount of crushed stone aggregates are present in the sealing layer, which will generate a large amount of dust and solid particles during the paving process, which can easily pollute the on-site environment. Therefore, a synchronous dust removal process is performed during the paving process, and the dust and solid particles are collected or settled separately. Dust removal is often completed by spraying water. Then, the water spray pipe in the existing asphalt gravel synchronous sealing dust removal device often sprays directly onto the sealing layer. On the one hand, due to the strong force of the spray water, the spray water will splash, thereby aggravating the flying of dust, making the subsequent adsorption and collection of dust more difficult; on the other hand, the splashing of the spray water will mistakenly enter the dust suction pipe of the dust suction pipe, affecting the downward transmission of the dust suction wind force, and further affecting the dust adsorption and collection effect of the dust suction pipe.

[0004] Therefore, it is necessary to invent a dust removal device for asphalt chipping synchronous sealing layer that can prevent water from splashing to solve the above problems. Utility Model Content

[0005] In order to address the deficiencies of the prior art, the purpose of the utility model is to provide a dust removal device for asphalt gravel synchronous sealing layer that can prevent water splashing. The utility model solves the problem that the water spray pipe in the dust removal device in the prior art often sprays directly onto the sealing layer. On the one hand, the spray water splashes due to the strong force of the spray water, thereby aggravating the flying of dust and making the subsequent adsorption and collection of dust more difficult; on the other hand, the splashing of the spray water may mistakenly enter the dust suction duct of the dust suction pipe, affecting the downward transmission of the dust suction wind force, and further affecting the dust adsorption and collection effect of the dust suction pipe.

[0006] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0013] As a preferred solution of the utility model, the part of the vacuum tube located below the mounting plate is detachably sleeved with a clamping ring, and the bottom end of each water distribution pipe is connected to a plug column that can vertically penetrate the clamping ring.

[0015] In the utility model, the flying dust is adsorbed and collected by the dust suction pipe, and in the process of adsorption and collection, the water spray pipe of the water diversion pipe can spray water horizontally, so that the sprayed spray water is sprayed onto the guide plate, and is diverted through the diversion groove on the guide plate.

[0024] When the pulling rod 18 slides along the bottom surface of the mounting plate 1 to the point closest to the center of the mounting plate 1, the multiple guide plates 13 are in a vertical state. When the pulling rod 18 slides along the bottom surface of the mounting plate 1 toward the direction away from the center of the mounting plate 1, the angle between the rotating plate 12 and the water distribution pipe 9 gradually increases, that is, the angle between the guide plate 13 and the water distribution pipe 9 increases, that is, the angle between the diversion groove 14 and the road surface is changed, thereby changing the common spraying area of ​​the multiple water distribution pipes 9.

[0025] The bottom surface of the mounting plate 1 is provided with a slide rail 15 at the position of each water distribution pipe 9, and the slide rail 15 is provided with a slide seat 16 for horizontal sliding. The slide seat 16 is rotatably connected to one end of the pulling rod 18. The sliding drive of the slide seat 16 along the slide rail 15 can be electrically driven, or a cylinder can be used to push the slide of the slide seat 16, which belongs to the mature existing technology and is not drawn in the figure.

[0026] The bottom surface of the mounting plate 1 is adapted to be connected with a first clamping seat 11 at the position of each water distribution pipe 9, the rotating plate 12 is rotatably arranged in the first clamping seat 11, the bottom end of the slide 16 is connected with a second clamping seat 17, and a side wall of the rotating plate 12 is connected with a third clamping seat 19, one end of the pulling rod 18 is rotatably connected to the second clamping seat 17, and the other end of the pulling rod 18 is rotatably connected to the third clamping seat 19. The first clamping seat 11 can facilitate the rotation between the rotating plate 12 and the mounting plate 1, and the second clamping seat 17 and the third clamping seat 19 can facilitate the rotation of the pulling rod 18, so that the lateral sliding of the slide 16 can quickly drive the pulling rod 18 to rotate, and then quickly drive the rotating plate 12 to rotate.

[0027] A dust collecting bucket 4 that can collect dust and provide adsorption force is arranged at the top of the dust suction pipe 3. A sealing plate 5 is detachably abutted against the bottom end of the dust suction pipe 3. A plurality of dust suction ports 6 for dust to pass through are opened in the sealing plate 5. The dust collecting bucket 4 is connected to a fan that provides adsorption force for the dust suction pipe 3.

[0028] A protective cover 2 is detachably abutted against the top of the mounting plate 1. The dust collecting bucket 4 and the circular tube 7 are both located inside the protective cover 2. The side wall of the circular tube 7 is connected to a water supply pipe 8 which can transversely penetrate one side wall of the protective cover 2 and extend to the outside. The water supply pipe 8 is connected to a spray water storage bucket, and spray water is then provided to the circular tube 7 through the water supply pipe 8, thereby providing spray water to each water distribution pipe 9 and each water spray pipe 10.

[0029] The part of the dust suction pipe 3 located below the mounting plate 1 is detachably sleeved with a clamping ring 20, and the bottom end of each water distribution pipe 9 is connected to a plug post 21 which can longitudinally penetrate the clamping ring 20. The plug post 21 is longitudinally inserted in the clamping ring 20, and the clamping ring 20 can be used to fix the position of the water distribution pipe 9 on the side wall of the dust suction pipe 3.

[0030] In the utility model, the flying dust is adsorbed and collected by the dust suction pipe 3, and in the process of adsorption and collection, the water spraying pipe 10 of the water diversion pipe 9 can spray water horizontally, so that the sprayed water is sprayed onto the guide plate 13, and is diverted by the diversion groove 14 on the guide plate 13. On the one hand, it can effectively prevent the spray water from directly impacting the road surface at high speed and causing splashing everywhere, and on the other hand, the guide plate 13 and the diversion groove 14 make the spray water flow to the road surface at a lower speed along the diversion groove 14, which not only expands the radiation of the spray water, but also improves the water absorption rate of the spray water. The spray water can cover the road surface with a large spray area and effectively prevent the spray water from directly impacting the road surface at high speed and aggravating the flying of dust, which is convenient for the subsequent adsorption and collection of dust. The falling spray water will wrap the solid particles and fall to the road surface together, so that the solid particles will settle. At the same time, due to the existence of the guide plate 13 and the diverter groove 14, the spray water flows along the diverter groove 14 to the road surface at a lower speed, which prevents the spray water from splashing and accidentally entering the dust suction pipe 3, and minimizes the downward transmission of the dust suction force, thereby improving the adsorption and collection effect of the dust suction pipe 3.
