Abstract
Description
Technical Field
[0001] This utility model belongs to the field of road construction technology, and in particular relates to a road roller for roadbed construction. Background Technology
[0002] Subgrade compaction is a crucial step in road construction, directly affecting not only the strength and stability of the road but also its service life. Road rollers are one of the important construction facilities for subgrade compaction, mainly consisting of a tractor and a compaction wheel. The tractor is used to move the compaction wheel, which is used to compact the subgrade.
[0003] A road roller for subgrade construction is disclosed in the existing patent announcement document CN118686036B, including a connecting seat, which is located at the front end of the roller frame. A roller is movably mounted at the front end of the connecting seat. A protective shell is installed at the upper end of the connecting seat and at the upper end of the roller. An adjustment component is installed at the lower end of the connecting seat. A scraping component is provided in the side wall of the connecting seat, with its end close to the roller. The adjustment component includes a drive component, a toggle component, and a connecting component. The drive component and the connecting component are both located on the bottom wall of the connecting seat. The toggle component is movably mounted on the drive component and connected to it. The connecting component is located at the lower end of the drive component and the toggle component.
[0004] However, it still has the following drawbacks in practical use:
[0005] The road roller mentioned above has a scraping component including a push plate and a scraper plate. The push plate and other structures drive the scraper plate to move, so that the scraper plate contacts the roller wheel. In turn, the rotation of the roller wheel achieves the scraping of the mud on the roller wheel. However, it is not convenient to clean the mud stains on the surface of the roller wheel during use, and the cleaning effect is poor.
[0006] The road rollers mentioned above compact the roadbed with rollers and clean the rollers with scraper components. However, during use, they are not convenient for leveling the roadbed, and the unevenness of the roadbed itself affects the compaction effect.
[0007] To address these issues, we provide a road roller for subgrade construction. Utility Model Content
[0008] The purpose of this utility model is to provide a road roller for roadbed construction. The roller is wiped by a sponge in the cleaning component and flushed by a high-pressure nozzle and a water distributor, which solves the problem of unsatisfactory cleaning effect of existing rollers. At the same time, the second hydraulic cylinder drives the mounting plate and the paving plate to rise and fall, and the paving plate flattens the roadbed, which solves the problem of the inconvenience of paving and compacting the roadbed.
[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

A cleaning component for cleaning the compaction wheel is provided on the top of the mounting frame, and a paving component for paving the roadbed is provided on one side of the mounting frame.
[0011] The cleaning assembly includes a U-shaped frame fixedly connected to the top of the mounting frame, a lifting plate movably connected inside the U-shaped frame, a sponge for wiping the roller fixedly connected to the lower surface of the lifting plate, mounting brackets fixedly connected at equal intervals along the length of one outer wall of the lifting plate, a flushing pipe penetrating through the inclined surface of the mounting bracket, a high-pressure nozzle fixedly connected to the end of the flushing pipe near the roller, and a water distributor fixedly connected to the end of the flushing pipe away from the roller.
[0012] The paving assembly includes a second hydraulic cylinder fixedly connected to the front and rear ends of one side of the outer wall of the mounting frame. An L-shaped plate is fixedly connected to the bottom end of the output shaft of the second hydraulic cylinder. The same mounting plate is fixedly connected to the vertical support arm of the L-shaped plate. A paving plate is movably connected to the side of the mounting plate away from the L-shaped plate. A buffer spring is also fixedly connected between the mounting plate and the paving plate.
[0013] A further feature of this invention is that a scraper is fixedly connected longitudinally to one side of the inner side of the mounting frame, and one end of the scraper abuts against the outer wall of one side of the rolling wheel.
[0014] A further feature of this invention is that a first hydraulic cylinder is fixedly connected to the top of the U-shaped frame, and the output shaft of the first hydraulic cylinder passes through the longitudinal support arm of the U-shaped frame and is fixedly connected to the center position of the upper surface of the lifting plate.
[0015] A further feature of this invention is that both sides of the front and rear end faces of the lifting plate are fixedly connected to protrusions, and the end of the protrusion away from the lifting plate is movably connected to the inside of a groove located on the inner wall of the U-shaped frame.
[0016] A further feature of this invention is that multiple connecting plates are fixedly connected at equal intervals along the length of the outer wall of the water distributor near the mounting frame, and the end of the connecting plate away from the water distributor is fixedly connected to the top of the mounting frame.
[0017] A further feature of this invention is that a fixing plate is fixedly connected to the center of one side of the outer wall of the mounting frame, a water storage tank is fixedly connected to the upper surface of the fixing plate, a submersible pump is fixedly connected to the bottom inner side of the water storage tank, a connecting hose is fixedly connected to the outlet end of the submersible pump, and the end of the connecting hose away from the submersible pump extends to the outside of the water storage tank and is fixedly connected to the inlet end of the water distributor.
[0018] A further feature of this invention is that L-shaped frames are fixedly connected to both the front and rear ends of the outer wall of one side of the mounting frame, and the second hydraulic cylinders are fixedly connected to the top of the horizontal support arm of the L-shaped frame.
[0019] A further feature of this invention is that: a fixing rod is fixedly connected to both the front and rear ends of the outer wall of the mounting plate near the L-shaped plate, and the end of the fixing rod away from the mounting plate passes through the vertical support arm of the L-shaped plate and is threaded with a fastening nut.

[0021] This utility model has the following beneficial effects:
[0022] This invention, through the installation of a cleaning component, activates a first hydraulic cylinder. The output shaft of the first hydraulic cylinder drives a lifting plate to move, which in turn moves a sponge and a high-pressure nozzle closer to the roller. The sponge then comes into contact with the top of the roller. Next, a submersible pump is activated, allowing flushing water from the storage tank to enter the flushing pipe through a connecting hose and a water distributor. Finally, the water is sprayed onto the surface of the roller through the high-pressure nozzle, effectively cleaning the mud and grime from the roller surface. This improves the cleaning efficiency, simplifies the use of the roller, and reduces the workload of workers.
[0023] This invention, by setting up a leveling component, activates a second hydraulic cylinder. The output shaft of the second hydraulic cylinder drives the mounting plate and the paving plate to rise and fall via an L-shaped plate, thereby making the bottom of the paving plate fit against the roadbed. Then, when the compaction wheel moves, the moving paving plate levels the roadbed, making it easier to level the roadbed and avoiding the impact of uneven roadbed on the compaction effect, thus facilitating the compaction of the roadbed.
[0024] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
