Description

Technical Field

[0001] This utility model relates to the field of compaction device technology, and in particular to a compaction device for road construction. Background Technology

[0002] Compactors are widely used in engineering projects such as roads, embankments, airport runways, and port terminals. They can crush, settle, and compact soil, making it more compact. In road construction, compactors can compact the roadbed, increasing the smoothness and load-bearing capacity of the road surface, improving its strength and stability, reducing the permeability of the roadbed, and minimizing uneven deformation caused by freezing. This ensures that the road surface has sufficient mechanical strength and stability to resist vehicle loads, thus extending the service life of the road.

[0003] Chinese utility model patent CN221877615U discloses a compaction device for road construction, including a base plate. A water tank is fixedly connected to the top of the base plate, and a pipe is fixedly connected to the middle of the bottom surface of the water tank. The pipe passes through the base plate and is fixedly connected thereto. A water conveying plate is fixedly connected to the bottom surface of the pipe. Rollers are fixedly connected to the front and rear of the bottom surface of the base plate. A connecting component is provided on the front side of the roller. An inclined plate is provided at the lower part of the connecting component. A cleaning component is provided at the lower part of the inclined plate. A snap-fit ​​component is provided on the left side of the cleaning component.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: When the scraper and the roller are in contact, the scraper only scrapes the gravel and soil off the surface of the roller after they come into contact with the scraper, and then the soil falls back to the ground. It is easy for the roller to come into contact with the soil again, requiring the scraper to clean it again, which increases the wear of the scraper. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a compaction device for road construction.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a compaction device for road construction, including a mounting plate, a mounting shell provided at the bottom of the mounting plate, a road roller for compacting the road rotatably connected inside the mounting shell, two mounting shells and two road rollers symmetrically arranged about the mounting plate, a scraping component for scraping off debris adhering to the surface of the road roller provided on one side of each of the two mounting shells, a connecting plate provided on the mounting plate, a cleaning component for cleaning debris on the road provided on the connecting plate, two sets of the cleaning component symmetrically arranged about the connecting plate.

[0007] By adopting the above technical solution, the workers first move the compaction device to the roadbed, and then drive the roller to compact the roadbed. The roller can compact the roadbed, increase the smoothness and load-bearing capacity of the road surface, improve the strength and stability of the road surface, and thus help to extend the service life of the road. The scraping component helps to remove debris adhering to the surface of the roller, thus improving the compaction effect of the roller on the roadbed. The cleaning component cleans the debris such as gravel and mud on the road surface, which helps to reduce the probability of gravel, mud and other debris repeatedly adhering to the surface of the pressure roller, thereby reducing the wear on the scraper and reducing the replacement efficiency of the scraper.

[0008] Furthermore, each of the scraping components includes a fixing plate disposed on one side wall of the mounting housing and a scraper disposed on one side of the fixing plate. The side of the scraper away from the fixing plate is in contact with the roller. A T-shaped groove is provided through the side of the fixing plate near the roller. A T-shaped slider that slides in cooperation with the T-shaped groove is fixed on the side of the scraper away from the roller.

[0009] By adopting the above technical solution, when debris such as gravel or soil adheres to the surface of the roller, the close contact between one side of the scraper and the roller helps to effectively remove these debris. This effective removal process improves the protection of the roller, thereby reducing the probability of unevenness on the roller surface caused by the presence of debris. This extends the service life of the roller and ensures the quality of road compaction, preventing unevenness from affecting the compaction effect.

[0010] Furthermore, each cleaning component includes an L-shaped plate fixed to one side of the connecting plate, a negative pressure machine fixed to the top of the horizontal plate of the L-shaped plate, a storage box fixed and connected to the exhaust port of the negative pressure machine, a connecting pipe fixed and connected to the top of the storage box, an inclined pipe fixed and connected to the lower end of the connecting pipe, and an inclined plate disposed on one side of the inclined pipe. The horizontal plate of the L-shaped plate has a through hole for the inclined pipe to pass through.

[0011] By adopting the above technical solution, the inclined plate scoops up the soil and other debris adhering to the ground. Then, the staff starts the negative pressure machine. After the negative pressure machine is working, it generates high suction and pressure, and air is discharged at high speed. The air at the front end of the negative pressure machine is continuously replenished, forming an instantaneous vacuum and creating a negative pressure difference with the external atmospheric pressure. The gravel, soil and other debris are collected into the storage box through the inclined pipe and connecting pipe. This helps to reduce the probability of the road roller repeatedly adhering to soil and other debris, and reduces the wear efficiency of the scraper.

[0012] Furthermore, a mounting bracket is fixed to the top of the mounting plate near its edge. The mounting bracket is provided with a drive assembly for driving the cleaning component to move up and down. The drive assembly includes a drive motor fixed to the top of the mounting bracket, a threaded rod rotatably mounted between the bottom of the mounting bracket and the top of the mounting plate, and a guide rod fixed between the bottom of the mounting bracket and the top of the mounting plate. The connecting plate is sleeved on the threaded rod and threadedly connected to the threaded rod. The connecting plate is sleeved on the guide rod and slidably engaged with the guide rod.

[0013] By adopting the above technical solution, the staff starts the drive motor, which drives the threaded rod to rotate. Since the connecting plate is threadedly connected to the threaded rod, the connecting plate and the guide rod slide together, and the connecting plate is fixed to the L-shaped plate, the L-shaped plate and the cleaning component move vertically. When the cleaning component is not needed, the staff starts the drive motor, which drives the L-shaped plate and the cleaning component to gradually move away from the mounting plate. This helps to reduce the obstruction of the cleaning component to the roller and ensures that the roller is not subjected to unnecessary interference during operation.

[0014] Furthermore, a pull-out box is slidably fitted on one side of the storage box, a handle is fixed on one side of the pull-out box, ventilation holes are provided through both sides of the pull-out box, and the top of the pull-out box is open.

[0015] By adopting the above technical solution, when a lot of debris accumulates in the storage box, the staff can remove the debris by sliding the pull-out box outwards, which is beneficial to the normal use of the storage box in the later stage.

[0016] Furthermore, the inclined plate and the inclined tube are connected by a hexagon socket head cap screw, which passes through the inclined tube and has a clearance fit with the inclined tube, and is also connected to the inclined plate by a thread.

[0017] By adopting the above technical solution, it is easier for staff to replace severely worn tilt plates.

[0018] Furthermore, a sealing ring is provided on one side of the pull-out box, and a traction hook is provided on the side of the L-shaped plate away from the roller.

[0019] By adopting the above technical solution, the sealing ring is designed to improve the sealing between the negative pressure machine and the storage box, thereby improving the adsorption capacity for debris such as gravel and soil; the traction hook makes it easier for workers to move the compaction device.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. In this application, the workers first move the compaction device to the roadbed, and then drive the roller to compact the roadbed. The roller can compact the roadbed, increase the smoothness and load-bearing capacity of the road surface, improve the strength and stability of the road surface, and thus help to extend the service life of the road. The scraping component helps to scrape off the debris adhering to the surface of the roller, which helps to improve the compaction effect of the roller on the roadbed. The cleaning component cleans the debris such as gravel and mud on the road surface, which helps to reduce the probability of gravel, mud and other debris repeatedly adhering to the surface of the roller, thereby reducing the wear on the scraper and reducing the replacement efficiency of the scraper.

[0022] 2. In this application, when debris such as gravel or soil adheres to the surface of the roller, the close contact between one side of the scraper and the roller helps to effectively remove this debris. This effective removal process improves the protection of the roller, thereby reducing the probability of unevenness on the roller surface due to the presence of debris. This extends the service life of the roller and ensures the quality of road compaction, preventing unevenness from affecting the compaction effect.

[0023] 3. In this application, the inclined plate scoops up the soil and other debris adhering to the ground. Then, the staff starts the negative pressure machine. After the negative pressure machine is working, it generates high suction and pressure, and air is discharged at high speed. Meanwhile, the air at the front end of the negative pressure machine is continuously replenished, forming an instantaneous vacuum. A negative pressure difference is formed with the external atmospheric pressure. The gravel and soil and other debris are collected into the storage box through the inclined pipe and connecting pipe. This helps to reduce the probability of the road roller repeatedly adhering to soil and other debris, and reduces the wear efficiency of the scraper. Attached Figure Description

[0031] The mounting plate 1 is horizontally set, and the bottom of the mounting plate 1 is provided with a mounting shell 11. The road roller 2 is rotatably connected to the inside of the mounting shell 11 for compacting the road.

[0032] The scraping assembly 3 is disposed on one side of the mounting housing 11 and is used to scrape away debris adhering to the surface of the roller 2. Two sets of scraping assemblies 3 are provided and symmetrically arranged about the mounting plate 1. Each set of scraping assemblies 3 includes a fixing plate 31 and a scraper 32.

The scraper 32 is disposed on one side of the fixing plate 31, with the side of the scraper 32 away from the fixing plate 31 in contact with the roller 2, and a T-shaped slider 321 is fixed to the side of the scraper 32 away from the roller 2, which slides in cooperation with the T-shaped groove 311.

[0033] A connecting plate 12 is provided on the mounting plate 1, and the cleaning component 4 is mounted on the connecting plate 12 for cleaning debris on the road. Two sets of cleaning components 4 are provided and symmetrically arranged about the connecting plate 12. Each set of cleaning components 4 includes an L-shaped plate 41, a negative pressure unit 42, a storage box 43, a connecting pipe 44, an inclined pipe 45, and an inclined plate 46. The L-shaped plate 41 is fixed to one side of the connecting plate 12, and the negative pressure unit 42 (this is only a simplified illustration in the figure; the negative pressure unit 42 is existing technology and will not be described in detail here) is fixed to the top of the horizontal plate of the L-shaped plate 41. The storage box 43 is fixed to and connected to the exhaust port of the negative pressure unit 42, and the connecting pipe 44 is fixed to and connected to the top of the storage box 43. The inclined pipe 45 is fixed to and connected to the lower end of the connecting pipe 44. A through hole for the inclined pipe 45 to pass through is provided on the horizontal plate of the L-shaped plate 41, and the inclined plate 46 is located on one side of the inclined pipe 45.

[0034] A mounting bracket 13 is fixed to the top of the mounting plate 1 near its edge. A drive assembly 5 is mounted on the mounting bracket 13 to drive the cleaning assembly 4 up and down. The drive assembly 5 includes a drive motor 51, a threaded rod 52, and a guide rod 53. The drive motor 51 is fixed to the top of the mounting bracket 13. The threaded rod 52 is rotatably mounted between the bottom of the mounting bracket 13 and the top of the mounting plate 1. The guide rod 53 is fixed between the bottom of the mounting bracket 13 and the top of the mounting plate 1. A connecting plate 12 is sleeved on the threaded rod 52 and threadedly connected to it. The connecting plate 12 is sleeved on the guide rod 53 and slidably engaged with it.

[0035] To facilitate the normal use of the storage box 43 in the future, a pull-out box 431 is slidably fitted on one side of the storage box 43. A handle is fixed on one side of the pull-out box 431, and ventilation holes are opened through both sides of the pull-out box 431 to facilitate the circulation of negative pressure air. The top of the pull-out box 431 is open. When a lot of debris accumulates in the storage box 43, the staff can remove the debris by sliding the pull-out box 431 outward, which is conducive to the normal use of the storage box 43 in the future.

[0036] To facilitate the replacement of severely worn inclined plate 46 by staff, inclined plate 46 and inclined tube 45 are connected by threaded hexagonal bolts (the figure is only a simple illustration, hexagonal bolts are existing technology and will not be described in detail here). The hexagonal bolts pass through inclined tube 45 and are clearance-fitted with inclined tube 45. The hexagonal bolts are threaded to inclined plate 46.

[0037] In order to improve the sealing between the negative pressure machine 42 and the storage box 43, and thus improve the adsorption capacity of gravel and soil, a sealing ring is provided on one side of the pull-out box 431 (not shown in the figure; the sealing ring is existing technology and will not be described in detail here); in order to facilitate the movement of the compaction device by the workers, a traction hook 6 is provided on the side of the L-shaped plate 41 away from the roller 2.

[0038] The operating principle of the road construction compaction device in this embodiment is as follows: Workers first move the compaction device to the roadbed, then drive the roller 2 to compact the roadbed. The roller 2 compacts the roadbed, increasing the smoothness and load-bearing capacity of the road surface, improving its strength and stability, and thus extending the road's service life. When debris such as gravel or soil adheres to the surface of the roller 2, the scraper 32, in close contact with the roller 2, effectively removes this debris. This effective removal process enhances the protection of the roller 2, reducing the probability of unevenness caused by the presence of debris. In this way, the service life of the roller 2 is extended, while ensuring the quality of road compaction and avoiding the impact of uneven roller 2 surface on compaction effect. The inclined plate 46 scoops up the soil and other debris adhering to the ground. Then, the operator starts the negative pressure machine 42. After the negative pressure machine 42 is working, it generates high suction and pressure, and air is discharged at high speed. The air at the front end of the negative pressure machine 42 is continuously replenished, forming an instantaneous vacuum and creating a negative pressure difference with the external atmospheric pressure. The gravel and soil and other debris are collected into the storage box 43 through the inclined pipe 45 and the connecting pipe 44. This helps to reduce the probability of roller 2 repeatedly adhering to soil and other debris and reduces the wear efficiency of scraper 32.

[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
