Description

Technical Field

[0001] This utility model relates to the field of road roller technology, specifically a road roller with a sludge scraping mechanism. Background Technology

[0002] A road roller, also known as a soil compactor, road compactor, or road leveling machine, is a heavy-duty piece of machinery used for soil compaction, playing an indispensable role in road construction. Road rollers are mainly divided into two categories: steel-wheeled and tire-mounted. Classified by the type of roller, rollers include smooth rollers, grooved rollers, and sheep's foot rollers. Among these, smooth rollers are the most widely used, primarily for compacting the surface layer of road surfaces. Classified by axle, they can be divided into single-axle single-drum, double-axle double-drum, double-axle three-drum, and three-axle three-drum types. Road rollers are typically powered by internal combustion engines and employ mechanical or hydraulic transmission.

[0003] A typical road roller usually consists of an engine, transmission system, running gear, control system, frame, rollers, and electrical system. The engine provides power for the roller's movement and steering. The transmission system transmits the engine's power to the running gear, enabling the roller to move and travel on the work site. The control system controls the roller's direction of travel. The frame supports and connects the various components and drives the rollers to compact the road. The electrical system provides power and signal control for the roller's electrical components.

[0004] Traditional road rollers often suffer from soil, asphalt concrete, and cement concrete fabric adhering to their roller surfaces during compaction. If these adhering materials are not removed promptly, they not only affect the compaction effect but also degrade the overall compaction quality of the road surface. To address this issue, some road rollers incorporate scrapers with their ends tightly fitted to the roller surface. As the roller rotates, the scraper removes these adhering materials, ensuring effective compaction and improving the compaction quality of the road surface. However, this method is insufficient for thoroughly removing hard impurities from the roller surface using only scrapers, further impacting the subsequent compaction quality and effect. Therefore, a road roller with an integrated scraping mechanism is proposed. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a road roller with a mud scraping mechanism, which solves the aforementioned technical problems that not only cannot fully scrape mud from the roller, but also affect the subsequent road rolling quality and effect.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a road roller with a sludge scraping mechanism, comprising:

[0009] The roller body, and the connecting frame set on the front of the roller body, with the roller drum connected to the inner cavity of the connecting frame;

[0010] A fixed side plate is set on the top of the connecting frame, and a horizontal top plate is connected between the fixed side plates. A hydraulic rod and a liquid storage tank are respectively installed on the top of the horizontal top plate. A sludge scraper is added directly below the bottom of the horizontal top plate, and the sludge scraper is connected to the telescopic end of the hydraulic rod.

[0011] A side-mounted support is located on the front of the transverse top plate, with a pump body installed on top of the support. The pump body is connected to a liquid storage tank, and an impact nozzle is installed at the bottom of the support, connected to the pump body. The roller is driven by the roller body and connecting frame to perform the roller compaction operation. The pump body draws liquid from the storage tank and delivers it to the impact nozzle, which sprays the liquid onto the surface of the roller. A hydraulic rod on the transverse top plate moves the scraper up and down, ensuring a tight fit between the scraper and the roller surface. This process allows for thorough cleaning of the roller through rinsing and scraping, ensuring the cleanliness of the roller surface and guaranteeing the quality and effectiveness of subsequent roller compaction.

[0012] Preferably, a connecting seat is provided on the top of the scraper blade, and the connecting seat is connected to the telescopic end of the hydraulic rod, with a positioning groove formed at the center of the bottom of the connecting seat. The hydraulic rod can drive the connecting seat to move up and down, and the connecting seat can be connected to a corresponding structure through the positioning groove.

[0013] Preferably, a positioning block is installed at the top center of the scraper blade, and the shape and position of the positioning block correspond to those of the positioning groove. The end of the positioning block is fitted against the inner wall of the fixed side plate. When the scraper blade is connected to the connecting seat, the positioning block is inserted into the interior of the positioning groove, so that the connecting seat can drive the scraper blade to move in the same direction.

[0014] Preferably, the top of the pump body is connected to a merging pipe, and the merging pipe is connected to the liquid storage tank. The pump body can extract liquid from the liquid storage tank through the merging pipe.

[0015] Preferably, side connecting rods are installed on both sides of the impact nozzle, and the side connecting rods are rotatably connected to the side connecting seats. A first drive motor is coaxially connected to the end of the side connecting rod. The first drive motor can drive the side connecting rod to rotate on the side connecting seats, so that the pitch angle of the impact nozzle can be adjusted on the side connecting seats. This allows the impact nozzle to clean the surface of the scraper blade, thereby cleaning the scraper blade and ensuring the subsequent scraping effect on the road roller.

[0016] Preferably, a driven wheel is provided on the upper part of the outer side surface of the fixed side plate, and the driven wheel is coaxially connected to the transverse top plate. A driving wheel is engaged at the bottom of the driven wheel, and a second drive motor is coaxially connected to the end of the driving wheel. The second drive motor drives the driving wheel on the fixed side plate, and the driving wheel drives the driven wheel. The driven wheel drives the transverse top plate to rotate on the fixed side plate, thereby facilitating the replacement of the scraper blade and the connecting seat.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a road roller with a sludge scraping mechanism, which has the following beneficial effects:

[0019] This road roller equipped with a sludge scraper operates by driving the roller drum through the roller body and connecting frame. A pump extracts liquid from the storage tank and delivers it to the impact nozzle, which sprays the liquid onto the surface of the roller drum. A hydraulic rod on the transverse top plate moves the scraper blades up and down, ensuring a tight seal between the scraper blades and the roller drum surface. This not only allows for thorough sludge removal from the roller drum through rinsing and scraping operations but also ensures the cleanliness of the roller drum surface, guaranteeing the quality and effectiveness of subsequent road compaction.
