Description

Bitumen slurry coat sealing machine

The utility model genus is built, road maintainance machinery equipment.Be to mix and stir, pave the machinery of asphalt slurry seal coat.

With aggregate chips or sand is aggregate, is binder with the mulseal, adds powder (being generally cement) and water, and these four kinds of materials are mixed and stirred the slurry mixture that becomes to have mobile shape by a certain percentage, paves equably on the road surface, is called the asphalt slurry seal coat technology.

The asphalt slurry seal coat technology belongs to new technology, but development is very fast.The U.S. has worked out " asphalt slurry seal coat handbook ", and Japan has been applied to the construction on airport, and France has been applied to the speedway maintenance, and the asphalt slurry seal coat technology is being studied by China.The asphalt slurry seal coat that paves was to pave on the road surface by manually mixing and stirring in the past again, and the deficiency of being brought is: labor intensity of operating staff is big, and efficient is low, mixed and stirred and the quality that paves is difficult for guaranteeing.

The purpose of this utility model provides a kind of labor intensity of operating staff that alleviates, and the efficient height mixes and stirs the uniform asphalt slurry seal coat machine that paves.

Characteristics of the present utility model are: it is a tractor with automobile or tractor, draw transmission system, hopper, mixing cylinder are installed on the chassis (or trailer), groove paves.On the chassis, water tank, mulseal case, hydraulic oil container and cleaning fuel tank are equipped with in the front portion, and the middle part is equipped with aggregate hopper, powder feeder, is reached transmission system, and mixing cylinder is equipped with at the rear portion, and the chassis afterbody hangs with the groove that paves.

The proportional control way of four kinds of materials is: aggregate, powder are controlled with the bin gate aperture adjustment of dispenser, and the discharge capacity of mulseal is certain, and water is controlled by valve.By Diesel Driven, water pump, bitumenpump, belt conveyor, dispenser, four kinds of materials are sent into mixing cylinder.

Be welded with tilting stirring width of cloth bar on the mixing cylinder axle, stir the other end welding helical steel band and the agitating plate of width of cloth bar, form a rigid body.Under the driving of diesel engine, whole rigid body rotation stirs into uniform thin pulp to four kinds of materials that enter in the mixing cylinder.Thin pulp in the mixing cylinder, shape advances in the shape of a spiral, reaches the purpose of uniform mixing.The thin pulp allowance of the tube door aperture of mixing cylinder in can application cylinder, the thin pulp from the tube door is discharged flows into the groove that paves through tripper.

The groove that paves is the rectangle frame construction, and the no end, rubber tile is arranged at the bottom around the framework, is used for preventing that thin pulp from overflowing, and pulls out lateral frame and paving width can be adjusted in 3-35 rice scope.The rubber flap that paves on the groove is connected with framework by the Fast Installation device, is the lever hold-down mechanism by adorning device fast, and is easy for installation.The camber limiter can be aligned voluntarily according to crown of pavement, and the road surface after guaranteeing to pave is identical with former crown of pavement.The paving thickness adjuster is the screw rod that withstands on the former road surface, and the afterbody of the groove that paves is lifted, to adjust paving thickness.Hydraulic motor drives helical spreader, and the bitumen slurries that inflow is paved in the groove further stirs, and thin pulp is pushed to around the framework.The groove that paves advances with car is dilatory, and bitumen slurries just flows out from the slit that the slot tail that paves lifts, and wipes off through rubber tile, forms the new road surface of asphalt slurry seal coat.

The power of the utility model transmission system is diesel engine, and its front end bent axle microcephaly drives water pump and hydraulic pump, and the rear portion clutch end is through total clutch reducer, divide clutch, drive bitumenpump respectively, belt conveyor, dispenser and mixing cylinder, hydraulic motor drives helical spreader.

The utility model, it is wide to have purposes, and construction is fast, and method is easy, and energy conservation and raw material reduce environment pollution, and construction cost is low, increases work efficiency, and guarantees the advantage of workmanship.Asphalt slurry seal coat surface finish, skid resistance, barrier properties, durability all improve a lot, and improve shape spoke spare, reduce the car abrasion, have prolonged application life, have than large economy, social benefit.
