Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery technology, specifically relating to a scraper device for a road roller. Background Technology

[0002] In road construction, road rollers are crucial equipment, playing a vital role in compacting road materials through gravity and mechanical vibration to ensure structural strength and smoothness. However, when the rollers come into contact with sticky materials (such as mud and asphalt), debris easily adheres, resulting in an uneven roller surface, affecting the compaction effect and causing road quality defects. Therefore, scrapers are widely used as a key accessory. They can promptly scrape off the adhered debris during the roller's rolling process, maintaining the cleanliness of the roller surface and ensuring efficient and stable compaction operations.

[0003] However, most existing scraper blades are designed to tilt downwards towards the roller. This structure causes debris to easily accumulate on top of the scraper blade. As the accumulation increases, the debris on top of the scraper blade generates additional friction with the roller, which not only exacerbates wear on the roller surface but also accelerates the damage to the scraper blade itself, significantly shortening the service life of both. At the same time, the debris accumulated on top of the scraper blade will fall to the ground from both ends. Especially when this debris falls onto already compacted ground areas, it will form bumps or depressions, seriously affecting the quality and smoothness of the compacted area. In addition, after a period of use, the scraper blade will experience a certain degree of wear, causing the gap between it and the roller to widen. This directly weakens the scraping effect of the scraper blade, making it difficult to completely remove debris from the roller surface. To maintain the normal working performance of the scraper blade, the gap needs to be adjusted frequently by hand, resulting in a significant reduction in construction efficiency and an increase in construction costs. Summary of the Invention

[0004] The purpose of this utility model is to provide a scraper device for a road roller, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A road roller scraper device includes two symmetrically arranged sets of mounting components and a scraper connected between the two sets of mounting components. The scraper is inclined upward toward the road roller's pressure roller. The mounting components include: a mounting base connected to a road roller mounting frame; a groove formed below the mounting base; a first slider slidably disposed in the groove; an adjusting mechanism that drives the first slider to slide away from the pressure roller in the groove; an elastic connector connected between the first slider and the mounting base; and a mud-blocking component connected below the first slider. The scraper is detachably connected to the mud-blocking component.

[0007] Preferably, the mounting base includes: a mounting plate and a mounting block connected to one side of the mounting plate. The sliding groove is formed at the bottom of the mounting block. Through grooves are formed on the left and right side walls of the sliding groove along its length. The left and right ends of the first slider are respectively provided with first connecting ears that can pass through the through grooves. The left and right outer side walls of the mounting block are respectively provided with second connecting ears. An elastic connector is provided between the first connecting ears and the second connecting ears on the same side.

[0008] Preferably, the elastic connector is a tension spring.

[0009] Preferably, the adjustment mechanism includes: a second slider slidably disposed in the groove and located on the side of the first slider near the pressure roller; an adjustment screw that movably passes through the first slider and is threadedly engaged with the second slider; the adjustment screw rotatably passes through the front sidewall of the groove; and a drive handle is provided at the extended end of the adjustment screw.

[0010] Preferably, the slide has a downward-opening T-shaped cross-section structure, and the first slider and the second slider have a T-shaped structure that cooperates with the slide.

[0011] Preferably, the mudguard component includes: a mudguard plate connected to the first slider, and a bracing plate disposed on the opposite sides of the mudguard plates of the two sets of mounting components and inclined upward toward the roller of the road roller, the scraper being detachably connected to the bracing plate, and the first slider extending downward and being detachably connected to the mudguard plate by bolts.

[0012] Preferably, the inclined support plate has a through-hole with a longitudinal waist shape, the scraper has countersunk holes at both ends, the scraper is connected to the inclined support plate by bolts, and the longitudinal waist shape is consistent with the width direction of the scraper.

[0013] Preferably, the mounting plate has a transverse oblong hole, the length direction of which is consistent with the length direction of the scraper.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] 1. This utility model designs the scraper to be installed at an angle towards the pressure roller. The scraped debris slides down the scraper surface under the action of gravity to the front of the pressure roller, which effectively prevents debris from accumulating between the scraper and the pressure roller, significantly reduces the wear caused by friction between the two, and extends the service life of the scraper and the pressure roller. At the same time, the mud-blocking component can prevent debris from falling from both ends of the scraper onto the compacted surface, effectively improving the flatness of the construction and the construction efficiency.

[0016] 2. This utility model, through the synergistic action of the elastic connector and the adjustment mechanism, presets an elastic preload during scraper installation. When the gap between the scraper and the pressure roller increases due to wear, the rebound force of the elastic connector drives the first slider to automatically compensate for the slight displacement of the scraper towards the pressure roller, maintaining a tight fit between the scraper and the pressure roller in real time. This eliminates the need for frequent manual adjustment of the gap, ensuring a long-lasting and stable sludge scraping effect, improving construction efficiency and reducing maintenance costs.

[0017] 3. In this utility model, when the pressure roller vibrates or its surface deforms, the elastic connector can absorb the impact energy through the elastic displacement of the first slider, thereby preventing the scraper from colliding or separating from the pressure roller, thus enhancing the adaptability of the device to complex working conditions and ensuring the continuity and stability of the sludge scraping operation.

[0018] 4. This utility model drives the second slider to move back and forth in the groove by adjusting the screw and the threaded engagement of the screw and the second slider. Combined with the elastic reset of the first slider, it realizes linear fine adjustment of scraper pressure and gap, which is convenient to operate and highly practical. Attached Figure Description

[0032] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0033] like Figures 1-5 As shown, a road roller scraper device includes two sets of symmetrically arranged mounting components 1 and a scraper 2 connected between the two sets of mounting components 1. The scraper 2 is inclined upward towards the road roller's pressure roller. The mounting components 1 include: a mounting base 3 connected to the road roller mounting frame; a groove 4 formed below the mounting base 3; a first slider 5 slidably disposed in the groove 4; an adjusting mechanism 6 that drives the first slider 5 to slide away from the pressure roller in the groove 4; an elastic connector 7 connecting the first slider 5 and the mounting base 3; and a mud-blocking component 8 connected below the first slider 5. The scraper 2 is detachably connected to the mud-blocking component 8.

[0034] It should be noted that: the mounting base 3 is connected to the existing road roller mounting frame by bolts, the length of the scraper 2 is consistent with the length of the pressure roller, and the scraper 2 can be made of commonly used composite materials such as nylon and polyurethane or rubber materials.

[0035] In use, the scraper 2 is in contact with the pressure roller, forming a rigid limit. Therefore, the adjusting mechanism 6 drives the first slider 5 to move away from the pressure roller. The elastic connecting piece 7 between the first slider 5 and the fixed block is stretched. The elastic preload of the elastic connecting piece 7 forces the first slider 5 to always tend to retract towards the pressure roller, thus converting the tension of the elastic connecting piece 7 into a continuous pressing force of the scraper 2 on the surface of the pressure roller. When the scraper 2 wears thin due to long-term use, the elastic return force of the tension spring drives the first slider 5 to move the scraper 2 slightly towards the pressure roller, automatically compensating for the wear thickness and ensuring the scraper... 2. Always in close contact with the pressure roller surface, eliminating the need for frequent manual gap adjustments, ensuring a long-lasting and stable sludge scraping effect, improving construction efficiency and reducing maintenance costs. When the road roller is operating, since the scraper 2 is tilted upwards towards the pressure roller, the scraped debris slides down the surface of the scraper 2 under the action of gravity to the front of the pressure roller, effectively preventing debris from accumulating between the scraper 2 and the pressure roller, significantly reducing wear caused by friction between the two, and extending the service life of the scraper 2 and the pressure roller. At the same time, the mud-blocking component 8 can prevent debris from falling from both ends of the scraper 2 onto the compacted surface, effectively improving the smoothness of construction and construction efficiency.

[0036] like Figure 1 and Figure 2 As shown, the mounting base 3 includes: a mounting plate 9 and a mounting block 10 connected to one side of the mounting plate 9. The sliding groove 4 is formed at the bottom of the mounting block 10. Through grooves 11 are respectively formed on the left and right side walls of the sliding groove 4 along its length direction. The left and right ends of the first slider 5 are respectively provided with first connecting ears 12 that can pass through the through grooves 11. The left and right outer side walls of the mounting block 10 are respectively provided with second connecting ears 13. An elastic connector 7 is provided between the first connecting ears 12 and the second connecting ears 13 on the same side.

[0037] By using the through groove 11 structure on the side wall of the mounting block 10, in conjunction with the first connecting ear 12 on the first slider 5 and the second connecting ear 13 on the mounting block 10, the tension spring is symmetrically installed, ensuring that the tension direction of the elastic connector 7 is strictly aligned with the slider movement direction, avoiding off-center load friction, and improving the stability of the elastic preload.

[0038] The elastic connector 7 is a tension spring; the detachable connection between the tension spring and the connecting ear facilitates the individual replacement of the elastic element, reducing maintenance costs.

[0039] Since the mounting holes on the mounting beam vary depending on the type of road roller, in order to ensure that scrapers 2 of the same length as the roller can be installed between the two sets of mounting components 1, a transverse waist-shaped hole 21 is provided through the mounting plate 9. The length direction of the transverse waist-shaped hole 21 is consistent with the length direction of the scraper 2, allowing the mounting base 3 to flexibly adjust its fixed position along the length direction of the scraper 2, thus adapting to the size differences of the mounting frame of different models of road rollers.

[0040] like Figure 3 and Figure 4 As shown, the adjustment mechanism 6 includes: a second slider 14 slidably disposed in the slide groove 4 and located on the side of the first slider 5 near the pressure roller; an adjustment screw 15 that movably passes through the first slider 5 and is threadedly engaged with the second slider 14; the adjustment screw 15 rotatably passes through the front sidewall of the slide groove 4; and a drive handle 16 is provided at the extended end of the adjustment screw 15.

[0041] The slide groove 4 has a T-shaped cross-section structure with the opening facing downwards, and the first slider 5 and the second slider 14 have a T-shaped structure that cooperates with the slide groove 4.

[0042] The working principle of the adjustment mechanism 6 is as follows: rotating the adjustment screw 15 drives the second slider 14 to slide away from the pressure roller, thereby pushing the first slider 5 forward synchronously. At this time, the elastic connector 7 connecting the first slider 5 and the mounting base 3 is stretched, generating an initial elastic preload. With the tension spring in a stretched state, the scraper 2 is fixed to the mud-blocking components 8 on both sides, ensuring that one side of the scraper 2 contacts the surface of the pressure roller, and the other side extends downward to form a mud-guiding structure. After the scraper 2 is installed, rotating the adjustment screw 15 in the opposite direction drives the second slider 14 to move closer to the pressure roller. When the first slider 5 loses the thrust and restraint of the second slider 14, the elastic preload of the elastic connector 7 forces the first slider 5 to always tend to retract towards the pressure roller. Since the scraper 2 has been in contact with the pressure roller to form a rigid limit, the scraper 2 is blocked by the pressure roller surface and cannot move towards the pressure roller. This causes the tension of the elastic connector 7 to be converted into a continuous pressing force of the scraper 2 on the pressure roller surface. When the scraper 2 becomes thin due to wear from long-term use, the elastic retraction force of the elastic connector 7 drives the first slider 5 to move the scraper 2 slightly towards the pressure roller, automatically compensating for the wear thickness and ensuring that the scraper 2 is always in close contact with the pressure roller surface.

[0043] like Figure 2 As shown, the mud-blocking component 8 includes: a mud-blocking plate 17 connected to the first slider 5, and a bracing plate 18 disposed on the opposite sides of the mud-blocking plate 17 of the two sets of mounting components and inclined upward toward the roller of the road roller. The scraper 2 is detachably connected to the bracing plate 18. The first slider 5 extends downward and is detachably connected to the mud-blocking plate 17 by bolts.

[0044] The inclined support plate 18 has a through-hole 19 in the longitudinal direction, and the scraper 2 has countersunk holes 20 at both ends. The scraper 2 is connected to the inclined support plate 18 by bolts, and the longitudinal hole 19 is consistent with the width direction of the scraper 2.

[0045] The bolted connection between the scraper 2 and the inclined support plate 18, and the mudguard 17 and the first slider 5, facilitates the partial replacement of worn parts and reduces downtime. The longitudinal waist-shaped hole 19 on the inclined support plate 18 matches the countersunk hole 20 of the scraper 2, so that scrapers 2 of different widths can be installed on the inclined support plate 18 and can fit against the surface of the pressure roller.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail can be made without departing from the spirit and scope of this utility model as defined in the appended claims.
