Description

Technical Field

[0001] The utility model relates to the technical field of asphalt rollers, in particular to a roller with a material spreading function for asphalt roads. Background Art

[0002] Asphalt, commonly known as asphalt concrete, is a mixture made by mixing mineral materials, crushed stone or crushed gravel, stone chips or sand, mineral powder, etc. with a certain proportion of road asphalt materials. Asphalt concrete is used to build road surfaces. Road rollers belong to the category of road equipment in heavy engineering machinery. They are also called earth rollers. They are a type of road construction equipment and are mainly used in filling and compaction operations in large-scale engineering projects such as high-grade highways and railways. Road rollers use the gravity of the machine itself to roll sandy, semi-viscous and viscous soils, roadbed stabilized soils and asphalt concrete pavement layers, causing the rolled layers to be permanently deformed and compacted.

[0003] In the prior art, a Chinese patent document with publication number CN217839596U and publication date January 8, 2022 is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: an asphalt concrete roller, comprising a machine body and a first roller, the first roller being rotatably connected to the machine body, a spray hood being provided above the first roller, the length direction of the spray hood being consistent with the length direction of the first roller, an inner cavity for storing water being provided in the spray hood, a plurality of spray heads being provided on the side of the spray hood facing the first roller, each of the spray heads being connected to the inner cavity, each of the spray heads facing the peripheral wall of the first roller, the spray hood being connected to a water supply pipe, one end of the water supply pipe being used to connect to a water source, and the other end of the water supply pipe being connected to the inner cavity, and a flow valve being provided on the water supply pipe.

[0004] In order to solve the problem of anti-sticking of asphalt concrete road rolling, the existing technology uses a flow valve to control the amount of water supplied to the inner cavity by a water supply pipe. The water in the inner cavity is sprayed out in the form of water mist through various spray heads, and the water mist is sprayed onto the peripheral wall of the first roller. The water mist is used to prevent adhesion. However, when asphalt falls on the road surface, it is in a piled state. Directly using a roller to roll it will cause the rolled road surface to be uneven and the asphalt thickness to be uneven, thus affecting the work quality. Utility Model Content

[0005] The utility model aims to provide a roller with a material spreading function for asphalt roads, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A roller with a material spreading function for asphalt roads comprises a roller body, and is characterized in that the roller body comprises a chassis, a control room is fixedly mounted on the top of the chassis, and moving wheels are arranged on both sides of the bottom of the chassis.

[0008] A material spreading unit is arranged on the rear end of the chassis, a rolling unit is arranged behind the material spreading unit, and a material scraping unit is arranged above the rolling unit.

[0009] A further improvement of the technical solution of the utility model is that the material spreading unit includes connecting transverse plates arranged on both sides of the rear end of the chassis, a supporting plate is welded to the middle position of the inner side of the connecting transverse plate, a connecting column is fixedly installed at the middle position of the supporting plate, and the supporting plate is convenient for connecting and installing the flat plate.

[0010] A further improvement of the technical solution of the utility model is that a paving plate is fixedly sleeved on the bottom end of the connecting column, and limiting plates are fixedly installed on both ends of the paving plate. The paving plate and the limiting plates are both closely connected to the ground. The paving plate can push the asphalt accumulated on the ground to cover the entire road surface to prevent unevenness caused by rolling. The limiting plates can drive the asphalt scattered on both sides of the road to move forward to prevent excess asphalt from accumulating on the road surface, thereby achieving the effect of saving resources.

[0011] A further improvement of the technical solution of the utility model is that the rolling unit includes a fixed rod fixedly installed and connected to the rear end of the inner side of the cross plate, and a pressure roller is rotatably sleeved on the outer surface of the fixed rod. The pressure roller rotates and fits on the ground. The pressure roller rotates on the outer surface of the fixed rod, which can roll the asphalt and improve the flatness of the road surface.

[0012] A further improvement of the technical solution of the utility model is that the scraper unit includes a supporting vertical plate fixedly installed on the top of the rear end of the connecting horizontal plate, a top plate is fixedly installed on the top of the supporting vertical plate, and scraper rods are fixedly installed on both sides of the top plate. The supporting vertical plate and the top plate facilitate the connection and installation of the scraper plate.

[0013] A further improvement of the technical solution of the utility model is that a scraper plate is fixedly installed on the other end of the scraper rod, and the scraper plate is closely connected to the outer surface of the pressure roller. The scraper plate is in close contact with the surface of the pressure roller. When the pressure roller moves during rolling, it moves relative to the scraper plate, thereby removing the asphalt adhering to the surface of the pressure roller during the rolling process.

[0014] A further improvement of the technical solution of the utility model is that a bearing plate is welded at the front end of the chassis, an asphalt storage box is fixedly installed on the top of the bearing plate, and a material guide port is fixedly installed on the bottom end of the asphalt storage box, so that the bearing plate facilitates the support of the asphalt storage box.

[0015] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0016] The utility model provides a roller with a material spreading function for an asphalt road. A spreading plate is provided to push the asphalt spread on the ground so that the accumulated asphalt is pushed and spread flat on the ground. A limiting plate is provided to drive the asphalt scattered to both sides to move forward, thereby preventing excess asphalt from accumulating on both sides of the road surface and causing waste, thereby achieving the effect of saving resources and improving work efficiency.

[0017] The utility model provides a roller with a material spreading function for an asphalt road. A pressure roller is arranged to closely follow a paving plate to roll the spread asphalt, so that the asphalt is compacted and the flatness of the road surface is improved.

[0018] 3. The utility model provides a roller with a material spreading function for asphalt roads. By setting a scraper plate in close contact with the surface of the roller, when the roller moves for rolling, it moves relative to the scraper plate to remove the asphalt adhering to the surface of the roller during the rolling process, thereby ensuring the flatness of the ground after rolling, avoiding shutdown for manual cleaning, and maintaining the progress of the construction work.
