Description

Mobile bitumen pellet lorry mounted mixer

The utility model belongs to pitch and the stone pellet is mixed mixed special equipment, is applicable to foster

Protect in the asphalt pavement constructions such as maintenance highway, airport, parking lot and stir pitch stone pellet.

Existing pitch pellet lorry mounted mixer though multiple model, specification are arranged, because of reasons such as needs external power supply and external asphaltic liquid storage tanks, all can only use in fixed venue.At fixed point, the pitch pellet mixed be contained on the truck fortune after mixed and go to pave the way.Because the pitch pellet of mixing after mixed can cooled and solidified, can not be for a long time, remote transportation, so can only being suitable for large tracts of land, this operation paves the way, mends the road, and among a small circle, the reparation construction of fragmentary dispersion, then inapplicable.Particularly in the maintenance work of daily bituminous highway, because point more than long lines moves frequently, compound cools off in transit, influences construction quality, and under cold snap, compound can condense and scrap especially; Or, influence construction task and finish because of under charge.

The purpose of this utility model is in order to solve in the road maintenance operation because of point more than long lines, moves frequently, makes the problem of the easy cooled and solidified of compound, and provides a kind of self generating that has, the mobile bitumen pellet lorry mounted mixer of pitch heating and heat preserving function.

The purpose of this utility model is reached by following technical scheme: it is to be provided with power drive mechanism on frame, oven dry mix drum apparatus, hydraulic control unit, burning heater, pitch time control metering device, electrical control gear, dust arrester, wheel etc., be provided with generating set in the frame front position, the rear is provided with insulation pitch case, described generating set comprises diesel engine, generator, the power transmission sequence of generator is connected with electrical control gear, described insulation pitch case is by outer case, an internal box and a lid are formed an enclosed housing, be provided with heat insulating material layer between internal box and the outer case, be provided with the electrothermal tube heater in this insulation pitch case.

Described electrothermal tube heater can have various ways, and electrothermal tube power can change, and electrothermal tube group number can change; Reach the electrothermal tube distribution and also can change, decide on mode of occupation.General electrothermal tube power is between 1～1.3KW, and general power is controlled within the 7.8KW, and the electrothermal tube grouping is distributed in the case.

The form of described insulation pitch case also can have various ways, shape.

The utility model has generating set because of self, can oneself power start-up operation, be provided with insulation pitch case, can the heat tracing asphaltic liquid, make the asphaltic liquid insulation, so the utility model can move with motor vehicle, construct along repairing circuit, and puddle needed optimum temperature range because of the asphaltic liquid temperature can be controlled at, so it is good that the pitch pellet mixes and stirs quality, materials are economized, not waste, and the border is on probation factually measures, compare every M with the cold-patch technology of manual watering's asphaltic liquid ³Pellet can be saved 150 kilograms of asphaltic liquids approximately.The utility model has solved the easy cooled and solidified problem of maintenance construction medium pitch mix particles material of repairing the roads for a long time, is highly suitable for point more than long lines, moves the reparation construction work of the flexible pavement of situations such as frequent and cold snap.

Further describe embodiment below in conjunction with accompanying drawing: present embodiment is made up of following parts in addition: 1 discharging hyoplastron, 2 asphalt thermal insulation casees, 3 bracing frame pin, 4 bitumenpump belt pulleys, 5 wheels, 6 bitumenpump motor, 7 fuel tanks, 8 hydraulic operation stations, 9 stacks, 10 generating sets, 11 hitch frames, 12 cases, 13 feed hoppers, 14 oil nozzles, 15 electric appliance boxes, 16 drying rollers, 17 bull gears, 18 mixing rollers, 19 dust arresters, 21 electrothermal tubes, 22 pipes, 23 insulation layers, 24 outer case, 26 internal box, 26 carriages, 27 protective covers, 28 gear type bitumenpumps, 29 pitch thermometers, 30 hangers, 31 top covers, 32 cellular spray bars, 33 elbows, 34 injection valve, 35 threeways, 36 oil discharging valves, 37 drain lines, 38 oil spout pipelines, 39 motor, 40 belt pulleys, 41 motor framves, 43 times oil discharging valves, 44 generators, 45 V belts, 46 V belts, 47 diesel engines, 49 diesel engine bases, 50 frames.

This machine is to be provided with power drive mechanism, oven dry mix drum apparatus, hydraulic control unit, burning heater, generating set, insulation pitch case, pitch time control metering device, electric apparatus control apparatus, dust arrester, wheel etc. on frame, and generating set is made up of diesel engine 47 and generator 44.Expansion screw 45 is equipped with in the base front portion of generator 44, is used for regulating the degree of tightness appropriateness of driving belt between diesel engine and the generator.The connection of stack 9 usefulness pipes is stretched under the frame, and waste gas is discharged down by machine.Diesel engine is dual-purpose by electricity startup, manual cranking.When considering the manual cranking diesel engine, enough spaces are arranged for handle is rotated, be contained in diesel engine on the base after, parallelly with generator more fixedly be installed on the frame with double-screw bolt.Insulation pitch case is formed a pre-small post-large T shape enclosed housing by outer case 24, internal box 25 and top cover 31, and volume 0.6m3 can adorn asphaltic liquid 500Kg approximately.Be installed in frame lower by carriage 26 and hanger 30 usefulness bolts.Use the asbestos wadding filling between internal box 25 and the outer case 24, form a thermal insulation layer, designing requirement per hour is that asphaltic liquid is lowered the temperature about 2 ℃ in the case.6 groups of power electrothermal tube 21 of 7KW altogether is housed in the case.Wherein preceding case is established 2 groups, and rear cabinet is established 4 groups, is fixed on the tank wall.If the asphaltic liquid temperature is lower than when mixing and stirring necessary requirement in the case, control by pitch thermometer 29 or with probe, can heat by power supply makes pitch to temperature required.When mixing and stirring, startup bitumenpump motor 39, V belt drive the belt pulley 4 that is contained on the bitumenpump, and asphaltic liquid promptly can by evenly spraying in the cellular spray bar, evenly be wrapped up in the pellet in the mixing cylinder and be applied into compound by pipe.The emitted dose of asphaltic liquid, can be by required bitumen aggregate ratio, with the metered flow of bitumenpump in the unit interval, regulating the time relay again controls quantitatively, the every work of bitumenpump once after, electrical apparatus control system promptly can be about to electric machine of asphalt pump reversing several seconds certainly, asphaltic liquid residual in the pipeline is sucked back casing, in order to avoid asphaltic liquid freezes blocking pipe.After construction is finished, if leave asphaltic liquid in the case, can close injection valve 34, open oil discharging valve 36, start special switch on the electric appliance box, bitumenpump 28 promptly can be with the residue asphaltic liquid by in the pipe 37 blowback basins, and the pitch lower box part also is equipped with standby oil discharging valve 43, fail the intact remaining asphaltic liquid of pump, valve is emitted thus.
