The course of work of the present utility model and operating principle are: start each electric-controlled parts of the present utility model by electrical control gear 10, make the utility model in running order.Start gazogene 1, make coal produce coal gas through burning; Simultaneously the different by size requirements of aggregate are delivered on the awl hopper 121 and the screen cloth 126 in the straight hopper 124 of three gradating material devices 12, aggregate is a sandstone, splendid attire is through the little aggregate of fine screen mesh 126 screenings in the awl hopper 121, splendid attire is through the big aggregate of wide-meshed screen 126 screenings in the straight hopper 124, the ossiculum material falls into transfer hopper 127 through bin gate 125, go out weight by weighing sensor 602 scales, simultaneously big aggregate falls into transfer hopper 127 through bin gate 125, go out weight by weighing sensor 602 scales, following little aggregate drops on belt conveyor 128 with big aggregate weight ratio on demand, and little aggregate is consistent with the ratio that big aggregate drops on belt conveyor 128, forms combined aggregate.When belt conveyor 128 carried aggregate to arrive aggregate hopper 21 tops of aggregate lifting appliance 2, aggregate fell in the aggregate hopper 21, and after aggregate hopper 21 was filled aggregate, manually-operated made three gradating material devices 12 carry out the work of next circulation.

Then manually-operated makes hoist engine 25 work, hoist engine 25 makes aggregate hopper 21 be risen by wire rope 26 tractions through the track of hoisting frame 23, when spacing when hitting plate 22 and running into upper limit travel switch 29,21 stop motions of aggregate hopper, aggregate hopper 21 topples aggregate is poured in the feed hopper 38 of charging aperture 3, and aggregate is in extension plate 36 falls into the dram 44 of aggregate dram 4.Then counter-rotating of hoist engine 25, empty aggregate hopper 21 is descending along track, stops on the ground basal plane, makes the wire rope 26 that connects hoist engine 25 lax, the lower limit travel switch 28 that is connected with wire rope 26 resets, 25 break-ofves of lower limit travel switch 28 control hoist engines.

Follow the coal gas in the ignition combustion device 100, coal gas is in combustion chamber tube 32 internal combustion, with flame and hot air input dram 44.Motor 47 drives pinion 46 rotations on the reductor 48 simultaneously, pinion 46 drives gear wheel 45 rotations of engagement, and gear wheel drives dram 44 rotations, and the aggregate in the dram 44 is stir-fried mixing and stirring swash plate 441 and mix and stir under straight plate 442 effects, guarantee the aggregate baking evenly, and aggregate is dried.The stopping means 42 of dram 44 ends has prevented dram 44 axial motions.The aggregate of oven dry is in discharging swash plate 443 enters the casing 54 of mixer 5, meanwhile the reinforced metering device 6 of pitch is pressed liquid bitumen in the constant weight adding mixer 5, powder feed metering device 7 is pressed constant weight with powder and is added in the mixer 5, falls into the stirring cylinder body 803 of a mixing bowl 8 after aggregate, liquid bitumen and powder converge by certain weight ratio in the mixer 5.

The course of work of the reinforced metering device 6 of pitch is: the pitch that has been heated into liquid enters three way cock 60 through advancing pitch pipe 601, the switch arm 604 of three way cock 60 rotates under the effect of valve cylinder 66, the pitch flow of control three way cock 60, make the pitch that needs flow into hopper 62 through going out pitch pipe 67, unnecessary pitch flows back to through returning pitch pipe 69, hopper 62 is hung on hanger 63 through dosing cylinder 62 and weighing sensor 602, pitch in the weighing sensor 602 weighing hoppers 62, when the pitch in the hopper 62 reaches the weight that needs, switch arm 604 closures of three way cock 60, pitch stops to enter hopper 62, and pitch is on the aggregate and powder of valve spraying in mixer 5 of pitch spreading tube 61.

The course of work of powder feed metering device 7 is: powder is added storage ash bucket 72, the powder that the helical axis of conveying worm 71 will store up in the ash bucket 72 promotes, powder enters weighing hopper 77 through powder delivery flexible pipe 75, weighing hopper 77 is hung on suspension bracket 76 through dosing cylinder 62 and weighing sensor 602, when the powder in the weighing hopper 77 reaches the weight that needs, powder is apparatus for ash under the gravity of dust inlet 55 settings of meal outlet 78 and mixer 5, enters mixer 5, converges with aggregate and pitch.

The course of work of a mixing bowl 8 is: motor 81 drives minor sprocket 83 rotations through reduction box 82, minor sprocket 83 drives hinge wheel 85 rotations through chain 84, hinge wheel 85 drives driving shaft 88 rotations, driving shaft 88 drives driven shaft 801 rotations by gear 804, stirring vane 87 rotations that are provided with on driving shaft 88 and the driven shaft 801, the aggregate, pitch and the powder that stir in the cylinder body 803 are mixed, form the finished product material.Start cylinder 806 discharge door 807 is opened, the finished product material is through blow tank 809 input finished product hoppers 91.Stir polylith abrasion-proof backing block 86 and the end face wearing plate 802 laid in the cylinder body 803, shield stirring cylinder body 803.

The course of work of finished bin 9 is: start hoist engine 25, it is up on the guide rail of guide rail bracket 93 that hoist engine 25 drives finished product hopper 91 through wire rope 26, when arriving storage warehouse 96, hoist engine 25 quits work under the effect of limit switch, and finished product hopper 91 is poured the finished product material into storage warehouse 96 and stored.Then hoist engine 25 counter-rotatings, empty finished product hopper 91 comes downwards to the ground basal plane, and hoist engine 25 quits work under the effect of limit switch.When the entrucking of needs finished product material is used, start door cylinder 92, door 97 is opened, and the finished product material gushes, the transportation wagon box of packing into.The finished product material can be paved the way and be repaired the roads.
