Road paver with automatic asphalt feeding structure

Abstract

The invention relates to the technical field of paving vehicles, and concretely relates to a road paver with an automatic asphalt feeding structure. The road paver comprises a vehicle body, an asphalttank mounted on the left side of the upper surface of the vehicle body, a shell mounted on the right side of the upper surface of the vehicle body, a shifting device movably mounted on the upper surface of the shell, and a first limiting rod mounted on one side of the shifting device. An angle control device is installed on the upper surface of the shell, an L-shaped supporting plate is installedon the left side of the vehicle body, a first hydraulic rod is installed on the upper surface of the L-shaped supporting plate, a connecting plate is installed at the upper end of the first hydraulicrod, and a pushing plate is installed at the left end of the connecting plate. Through mutual cooperation of the structures, an asphalt raw material feeding function is conveniently achieved, asphaltis prevented from difficultly entering the asphalt material box due to too large resistance, the asphalt feeding speed is conveniently adjusted through active feeding, dust, impurities and the like on an unpaved road surface can be conveniently swept, and the asphalt paving quality is improved.

Description

technical field [0001] The invention relates to the technical field of road paving vehicles, in particular to a road paving vehicle with an automatic asphalt feeding structure. Background technique [0002] Asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage from driving and natural factors, making the pavement smooth and less dusty. Permeable and durable, therefore, asphalt pavement is the most widely used high-grade pavement in road construction. The asphalt structural layer of asphalt pavement itself belongs to the category of flexible pavement, but its base layer can also use rigid materials in addition to flexible materials. Cement concrete, or semi-rigid hydraulic material, paving machines are commonly used to lay asphalt or concrete on roads, bridges, parking lots, and other construction sites. Such machines are usually equipped to...

Problems solved by technology

[0003] Existing paving vehicles can quickly and efficiently lay asphalt pavement. Because the paving requires a lot of asphalt, the existing paving vehicles need a truck to unload the material on the front of the paving vehicle, and pour the asphalt into the asphalt tank of the paving vehicle. At the same time, the paving vehicle is paving the road, but the existing paving vehicle does not have the function of automatic feeding. When the truck is unloading, the asphalt may be stuck on the surface of the truck, and it cannot be actively fed, and the feeding speed cannot be adjusted. There is no cleaning function in the process, which will easily lead to excessive impurities on the road surface and affect the service life of asphalt roads
