Description

Technical Field

[0001] This utility model relates to the field of asphalt paving technology, specifically to a multifunctional asphalt paving device. Background Technology

[0002] The technical background of asphalt paving equipment can be traced back to the needs of road construction industrialization. It has gradually developed from early manual paving to mechanized and intelligent equipment. Its core function is to spread hot-mix asphalt mixture evenly on the base layer to lay the foundation for subsequent compaction and shaping. Its performance directly affects the smoothness and durability of the road surface. However, in the existing technology, asphalt paving equipment often causes compaction problems due to uneven asphalt accumulation.

[0003] Fluctuations in raw material gradation and segregation during transportation and unloading can lead to imbalances in local asphalt content or aggregate distribution. Improper matching between the paver's auger distributor speed and paving speed can easily cause asphalt to accumulate too thickly or too thinly in edge areas. Temperature segregation results in poor asphalt fluidity and insufficient compaction in low-temperature areas. These problems manifest themselves during compaction—bulges form in areas with excessively thick accumulation because internal air cannot be completely expelled, while voids are generated in areas with insufficient material or concentrated aggregate due to inadequate asphalt bonding, severely reducing the structural strength and service life of the pavement. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional asphalt paving device, which has the advantages of fast asphalt homogenization and easy material compaction. It solves the problem in existing asphalt paving devices that cause bulges and holes during asphalt compaction due to uneven asphalt accumulation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-functional asphalt paving device includes a paving component and a mixing and compaction component. The mixing and compaction component is located at the front end of the paving component. The paving component includes a base. A splash guard is located at the front end of the base and is fixedly connected to the base. An asphalt pressure roller is located below the front end of the splash guard and is rotatably connected to the splash guard. A rotating shaft is located at the lower end of the splash guard and is rotatably connected to a bearing on the base. A crushing disc is located around the outer circumference of the rotating shaft and is rotatably connected to the outer shaft of the rotating shaft. An engine is located at the upper end of the base.

[0007] Preferably, a transmission wheel is provided on one side of the base, and the transmission wheel is rotatably connected to the base bearing.

[0008] It is worth noting that the drive wheel is used in the engine's power transmission structure.

[0009] Preferably, the transmission wheel and the rotating shaft are connected by a synchronous belt drive.

[0010] It is worth noting that the high-speed rotating shaft stirs and mixes the asphalt material to make it loose and homogeneous, thereby reducing the difficulty of asphalt compaction.

[0011] Preferably, both ends of the asphalt roller are provided with wheels, and the wheels are fixedly connected to the asphalt roller.

[0012] It is worth noting that the wheels at both ends of the asphalt roller are used to move and push the asphalt roller and the base.

[0013] Preferably, the lower ends of the base are provided with casters on both sides.

[0014] It is worth noting that the casters on both sides of the lower end of the base facilitate its movement.

[0015] Preferably, the power output end of the engine is connected to the transmission wheel via a synchronous belt drive.

[0016] It is worth noting that the engine drives the transmission wheel, which in turn drives the shaft to rotate.

[0017] Preferably, an oil tank is provided on one side of the engine, and the output end of the oil tank is connected to the oil input end of the engine via a pipeline.

[0018] It is worth noting that the fuel tank supplies fuel to the engine.

[0019] Preferably, the base has a handle at its rear end, and the handle is fixedly connected to the base.

[0020] It is worth noting that the handle is used to push and pull the base, which facilitates the compaction of the asphalt layer by the asphalt roller.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This invention uses an engine to drive a transmission wheel, which in turn drives a rotating shaft to rotate at high speed. The high-speed rotating shaft drives a crushing disc to rotate, and the rotating crushing disc crushes and mixes the asphalt material. After the operator manually pulls the handle, the asphalt pressure roller presses down and compacts the asphalt, thus realizing the functions of asphalt paving and compaction. Due to the rotation of the shaft and the crushing disc, the asphalt is hammered, crushed, and mixed, thereby effectively improving the paving efficiency and effect of the asphalt material layer.

[0023] The splash guard is designed to prevent material from splashing onto the rotating shaft. Attached Figure Description
