Description

Technical Field

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

[0002] In the construction of roadbed filling, compaction is a key step to ensure the compaction degree of the roadbed, which directly affects the bearing capacity and service life of the road. After the roadbed filling is completed, it needs to be compacted by a compaction device to improve the density and strength of the roadbed soil and reduce subsequent settlement and deformation.

[0003] Currently, commonly used roadbed filling and compaction devices mainly rely on compaction rollers rolling on top of the roadbed to achieve compaction. However, in actual construction, due to the cohesiveness of the roadbed fill material (especially fine-grained soils such as lime-soil and clay), the lime-soil easily adheres to the outer surface of the compaction roller during compaction. As the compaction operation continues, the lime-soil adhering to the surface of the compaction roller gradually accumulates, causing a change in the effective compaction diameter of the compaction roller, which in turn affects the smoothness of the roadbed surface, resulting in problems such as local undulations and uneven compaction. Utility Model Content

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a roadbed filling and compaction device, such as... Figure 1-5 As shown, the roadbed filling and compaction device includes: a mounting frame 1; a compaction roller 2 mounted on the mounting frame 1 via bearings for compacting the roadbed; a connecting frame 3 fixed to one side of the mounting frame 1 for connecting the moving equipment; a bracket 4 fixed on the mounting frame 1, with a height-adjustable scraper 8 below the bracket 4 for scraping off the soil adhering to the compaction roller 2; and an adjustment mechanism on the bracket 4 for adjusting the raising and lowering of the scraper 8.

[0022] In this embodiment, during use, the mobile device drives the mounting frame 1 and the compaction roller 2 to move via the connecting frame 3. The compaction roller 2 compacts the roadbed. When the surface of the compaction roller 2 is covered with soil, the scraper 8 is lowered to contact the surface of the compaction roller 2 via the adjustment mechanism on the operating bracket 4. As the compaction roller 2 rotates, the scraper 8 scrapes off the soil on its surface.

[0023] The adjustment mechanism can adjust the height of the scraper 8 according to the amount of soil and dust adhering to the surface of the compaction roller 2, so as to ensure that the scraper 8 and the compaction roller 2 maintain a suitable contact state, which can effectively scrape off the soil and dust without causing too much obstruction to the rotation of the compaction roller 2, thus ensuring the continuous operation of the compaction operation.

[0024] By cooperating with the scraper 8 and the adjustment mechanism, the dust and soil adhering to the surface of the compaction roller 2 can be removed in time, reducing the impact of dust and soil accumulation on the effective compaction diameter of the compaction roller 2. This helps to maintain the flatness of the roadbed compaction, reduce the probability of local undulations and uneven compaction, and improve the quality of roadbed filling and compaction.

[0025] In a further preferred embodiment of the present invention, the adjusting mechanism includes: an electric telescopic rod 5 fixed on the bracket 4, a groove block 6 fixed on the push rod of the electric telescopic rod 5; a plug block 7 fixed on the groove block 6 by bolts; a first mounting plate 9 fixed to the bottom of the plug block 7; a slide rod 11 slidably mounted on the first mounting plate 9; and a second mounting plate 10 slidably sleeved on the slide rod 11, the bottom of the second mounting plate 10 being fixedly connected to the scraper 8.

[0026] In this embodiment, when in use, the electric telescopic rod 5 is activated, and its push rod drives the groove block 6 and the plug block 7 to rise and fall, thereby driving the first mounting plate 9, the slide rod 11, the second mounting plate 10 and the scraper 8 to move synchronously, so as to realize the adjustment of the height of the scraper 8. The electric telescopic rod 5 provides a stable driving force to ensure the convenience of adjusting the height of the scraper 8.

[0027] In a further preferred embodiment of the present invention, a damping sleeve 13 and a spring 12 are sleeved on the slide rod 11, and limit blocks are fixed at both the top and bottom ends of the slide rod 11.

[0028] In this embodiment, when the scraper 8 contacts the surface of the compaction roller 2 and is subjected to a reaction force, the second mounting plate 10 slides along the slide bar 11, compressing or stretching the spring 12. The damping sleeve 13 moves with the second mounting plate 10 and generates a damping effect. The limiting block restricts the sliding range of the second mounting plate 10 to prevent it from disengaging from the slide bar 11.

[0029] The elastic force of spring 12 can buffer the impact force on scraper 8 and reduce the hard impact on scraper 8 when compaction roller 2 rotates; damping sleeve 13 can slow down the sliding speed of second mounting plate 10, making the contact between scraper 8 and compaction roller 2 more stable and reducing the wear caused by frequent collisions between the two.

[0030] This structure, through the cooperation of spring 12 and damping sleeve 13, enhances the buffering and adjustment capability of scraper 8, can adapt to the slight undulations on the surface of compaction roller 2, maintains stable contact between scraper 8 and compaction roller 2, helps to improve the continuity of dust and soil scraping, and at the same time extends the service life of scraper 8 and compaction roller 2, enhancing the reliability of the device.

[0031] In a further preferred embodiment of the present invention, a connecting plate 14 is fixedly installed on one side of the groove block 6, and a water spray pipe 15 is fixedly installed on the bottom of the connecting plate 14. A nozzle 16 is fixedly connected to the water spray pipe 15 for spraying water to rinse the scraper 8.

[0032] In this embodiment, the water spray pipe 15 is connected to an external water source, and the water flows out through the nozzle 16 to rinse the scraper 8; when the groove block 6 is raised and lowered, it drives the connecting plate 14 and the water spray pipe 15 to move synchronously, so that the nozzle 16 is always aligned with the part of the scraper 8 to be rinsed.

[0033] The combination of the water spray pipe 15 and the nozzle 16 can wash away the residual dust and dirt on the scraper 8, reducing the accumulation of dust and dirt on the surface of the scraper 8; the design of moving synchronously with the groove block 6 ensures the adaptability of the washing position and avoids incomplete washing due to changes in the position of the scraper 8.

[0034] By spraying water to rinse the scraper 8, the amount of dust and soil residue on the scraper 8 can be reduced, the scraping effect of the scraper 8 on the compaction roller 2 can be maintained, the possibility of dust and soil adhering to the compaction roller 2 again can be reduced, and the frequency of manual cleaning of the scraper 8 can be reduced, thus improving the continuous operation capability of the device.

[0035] In a further preferred embodiment of this utility model, a filter box 18 is fixedly installed on the connecting frame 3, and a telescopic pipe 17 is fixedly installed at the outlet of the filter box 18. The outlet end of the telescopic pipe 17 is fixedly connected to the spray pipe 15.

[0036] In this embodiment, external water enters the filter box 18 for filtration. The filtered water is then transported to the spray pipe 15 via the telescopic pipe 17 and sprayed out through the nozzle 16. When the spray pipe 15 rises and falls with the groove block 6, the telescopic pipe 17 extends and retracts accordingly to ensure the continuous connection of the water path.

[0037] The filter box 18 can filter the water flowing into the device, reducing the amount of impurities in the water entering the spray pipe 15 and the nozzle 16, thus reducing the risk of clogging; the telescopic feature of the telescopic pipe 17 can adapt to changes in the position of the spray pipe 15 and maintain the continuity of water supply.

[0038] In a further preferred embodiment of the present invention, a filter cartridge 19 is provided inside the filter box 18, and a sealing cover 20 is provided on the top of the filter box 18. A water inlet pipe 21 is fixedly connected to the sealing cover 20 for connecting to a water supply device.

[0039] In this embodiment, the water supply equipment supplies water to the filter box 18 through the water inlet pipe 21. The water flows into the filter cartridge 19 for filtration, and the filtered water flows out from the outlet of the filter box 18. The filter cartridge 19 can be replaced or cleaned by opening the sealing cover 20. The filter cartridge 19 filters the water entering the filter box 18 to reduce impurities in the water. The sealing cover 20 ensures the airtightness of the filter box 18 to prevent water leakage, and at the same time facilitates the maintenance of the filter cartridge 19.

[0040] In a further preferred embodiment of this utility model, hooks are fixedly installed on both sides of the sealing cover 20, and buckles are provided on both sides of the filter box 18, with the buckles engaging with the corresponding hooks.

[0041] In this embodiment, the snap-fit ​​structure of the hook and buckle can quickly realize the installation and removal of the sealing cover 20, simplifying the operation process when maintaining the filter cartridge 19; at the same time, the snap-fit ​​state can ensure the sealing between the sealing cover 20 and the filter box 18, reducing the occurrence of water leakage.

[0042] In summary, compared with related technologies, the compaction roller 2 is supported by the mounting frame 1 for roadbed compaction. The contact state between the scraper 8 and the compaction roller 2 is adjusted by the adjustment mechanism on the bracket 4, and buffering is achieved with the spring 12 and damping sleeve 13 on the slide rod 11. At the same time, the water spray pipe 15 and nozzle 16 are driven by the connecting plate 14 to wash the scraper 8. The water filtered by the filter box 18 and filter cartridge 19 is transported by the telescopic pipe 17. The hook of the sealing cover 20 and the buckle of the filter box 18 cooperate to ensure the sealing of the filtration system and convenient maintenance. This achieves timely removal of dust and soil from the surface of the compaction roller 2, reducing the impact of dust and soil accumulation on the compaction diameter.
