A kind of small-sized asphalt paver

Technical field

The utility model relates to a kind of road building machinery, relates in particular to a kind of small-sized asphalt paver.

Technical background

Asphalt remixer is widely used in the construction and the maintenance of the flexible pavement of highway, airport, harbour, parking lot and urban road, and its product can be divided into: (1) is by the running gear branch: rubber-tyred and crawler type are arranged; (2) divide by PWTN system: three kinds of fluid pressure type, mechanical type and hydraulic mechanical types are arranged; (3) have small-sized, medium-sized, large-scale by the paving width branch and four kinds of ultra-large types.Small-sized paver paving width is generally less than 3.6m, is mainly used in the maintenance of asphalt concrete pavement and paving of inferior grade road surface.Along with the particularly comprehensive startup of Country Road Construction that continues to increase of national basis Facilities Construction dynamics, to the demand of paver also in continuous increase.But existing paver price is all hundreds of thousands unit even 1,000,000 yuan generally, in ordinary highway construction or vast Country Road Construction, this equipment price surpasses the purchasing power of unit in charge of construction, thereby such situation occurs: the paver that on the one hand large quantities of manufacturing enterprises produce is not sell well, most on the other hand common roads particularly Country Road Construction do not adopt machine to pave but adopt manually to pave, make manufacturing enterprise and social demand produce serious disconnection.Investigate discovery through the inventor, the small-sized asphalt paver that present paver the most in short supply in the society is simple in structure, low price, operating cost is cheap.

Summary of the invention

The purpose of this utility model provides a kind of compact conformation, low price, small-sized asphalt paver that operating cost is cheap.

The technical solution adopted in the utility model is such: a kind of small-sized asphalt paver, comprise removable chassis of pulling and be located at hopper on the described chassis respectively, helix transporting device and drive unit thereof, ironing machine, described helix transporting device comprises that the mandrel that two ends are located on the chassis rotationally by bearing reaches two groups of helical blades being located at successively on the mandrel side, the hand of spiral of described two groups of helical blades is opposite, and mandrel one end is connected with drive unit, and described ironing machine is located at described helix transporting device downstream and is used to press the bituminous mixture that helical blade paves.

Above-mentioned small-sized asphalt paver, described drive unit comprise motor and connect the reduction box of described motor output that one end of described mandrel and the output of reduction box are in transmission connection.

Above-mentioned small-sized asphalt paver, described drive unit comprise motor and connect the oil pump of motor output, and an end of described mandrel is provided with hydraulic motor, be connected by oil pipe between described hydraulic motor and the oil pump, and described oil pipe is provided with control valve.

Above-mentioned small-sized asphalt paver, described ironing machine are that the bottom surface is the hollow box body on plane, and described casing is provided with air inlet port and exhaust head, and described air inlet port is communicated with the stack of described diesel engine.

Above-mentioned small-sized asphalt paver, described chassis are located on two groups of wheels, and described wheels are provided with wheel, and are provided with the adjusting device that is used to adjust chassis height between described wheels and the chassis.

The beneficial effect that the utility model is obtained: one, by adopting the small-sized asphalt paver of said structure, bituminous mixture is paved in the road surface and the preliminary compacting of quilt at short notice equably, compact conformation, cost is very cheap, and operating cost is also very low; Its two, this small-sized asphalt paver is widely used in Country Road Construction, does not meet manually paving of quality requirement thereby abandon, and has not only improved operating efficiency, has reduced labor strength, and can improve the planeness of highway and prolong application life of highway.Enumerate an embodiment below in conjunction with accompanying drawing and specify the utility model.
