Fig. 1 to Fig. 5 shows the structural schematic diagram of a preferred embodiment of the invention, the hard coagulation of one of Fig. 1
The dustless excavator in soil surface, including host 1, mechanical arm 2, turntable 3, diesel engine 4, water supply pump station 5, hydraulic power unit 6, sky
Press 7, joint-cutting milling mechanism 8, rotary motor 9, scraper bowl 10, creeper undercarriage 11, ultrasonic wave air atomizer spray nozzle 13, cooling
Nozzle 14, shield 15, feedwater piping 16, steam line 17 and scraper bowl control oil cylinder 18.Wherein, host 1 is pacified by turntable 3
On creeper undercarriage 11, mechanical arm 2 is hinged on host 1, diesel engine 4, water supply pump station 5, hydraulic power unit 6 and sky
Press 7 is mounted on host 1, and 4 outputting rotary power of diesel engine is transferred to creeper undercarriage 11, water supply pump station 5 respectively
With the plunger pump and air compressor machine 7 on hydraulic power unit 6, water supply pump station 5 is connected by feedwater piping 16, it is real by steam line 17
The connection of existing air compressor machine 7 and other structures.
Referring to fig. 2, joint-cutting milling mechanism 8 is hinged on the articulated stand of 2 front end of mechanical arm, and rotary motor 9 is mounted on hinge
It connects the side of bracket and is drivingly connected with for joint-cutting milling mechanism 8, rotary motor 9 is coupled with joint-cutting milling mechanism 8 and by hydraulic
The power drive of surging that pumping plant 6 exports, so that joint-cutting milling mechanism 8 be driven to work.Scraper bowl 10 is mounted on 2 front end of mechanical arm and is located at
The outside of joint-cutting milling mechanism 8 is connect with the scraper bowl control oil cylinder 18 for being located at 2 top of mechanical arm, and hydraulic power unit 6 drives scraper bowl control
Liquefaction cylinder 18, scraper bowl 10 is for removing broken concrete.Scraper bowl 10 can remove broken concrete and carry out ditching, mill with joint-cutting
It cuts the joint of mechanism 8 and realizes concrete disintegrating, removing and ditching institutional operation.
Referring to Fig. 3, mechanical arm 2 is also equipped with shield 15, and ultrasonic wave air atomizer spray nozzle 13 and cooling nozzles 14 are mounted on
On fixed mechanism in shield 15；The water that 14 position of cooling nozzles sprays will act on the local ability that blade is contacted with road surface
Cooling blade to greatest extent, so cooling nozzles 14 are corresponding with the quantity of joint-cutting blade 8-2 and position, multiple ultrasonic airs
Aerosolization nozzle 13 is arranged in above left side milling roller 8-1 and right side milling roller 8-3, and ultrasonic wave air atomizer spray nozzle 13 divides
It is not connect with water supply pump station 5 and air compressor machine 7, cooling nozzles 14 connect water supply pump station 5；Air compressor machine 7 using oilless air compressor so as to
In environmental protection.In general, the quantity of ultrasonic wave air atomizer spray nozzle 13 will be more than cooling nozzles 14, because cooling nozzles 14 are cooling
Blade, alignment just it is much of that, and ultrasonic wave air atomizer spray nozzle 13 be atomizing de-dusting diameter of cylinder it is big, width is big, and quantity is wanted
It is more.Preferably, the cooling nozzles 14 are located at the outside arrangement of ultrasonic wave air atomizer spray nozzle 13, do not interfere, effect is good；It is excellent
First, feedwater piping 16 and steam line 17 are laid with along mechanical arm 2.Ultrasonic wave air atomizer spray nozzle 13 is preferably using reinforced
Air atomizer spray nozzle strengthens atomization, easily facilitates dedusting, and realization is dustless to be turned into industry.Cooling nozzles 14 preferably with joint-cutting Milling Machine
Structure 8 moves at the same time, and acts on the joint-cutting blade 8-2 during grooving, cools down to it, protects joint-cutting blade 8-2, also simultaneous
Has depositing dust effect.Scraper bowl 10 and shield 15 also have the function of preventing broken concrete from disorderly collapsing, to prevent hurting sb.'s feelings.
As shown in Figure 4 and Figure 5, the joint-cutting milling mechanism 8 mainly by left side milling roller 8-1, joint-cutting blade 8-2 and
Right side milling roller 8-3 composition, is designed with coupling flange, joint-cutting knife on left side milling roller 8-1 and right side milling roller 8-3
Piece 8-2 is mounted on coupling flange by bolt 8-4.Concrete road surface 12 lower for hardness uses a joint-cutting blade 8-
2 and be placed in left side milling roller 8-1 and right side milling roller 8-3 among, to concrete road surface 12 carry out operation；For hardness compared with
High concrete road surface 12 is using multiple joint-cutting blade 8-2 and is mounted in the milling roller 8-1 and right side milling roller 8-3 of left side
Between and two sides, manufacture more Free Surfaces in order to which concrete road surface 12 is broken.
Working principle: when work, starting diesel engine 4 makes 7 work of water supply pump station 5, hydraulic power unit 6 and air compressor machine in turn
Make, the oil cylinder on joint operation turntable 3 and mechanical arm 2, so that the joint-cutting blade 8-2 of joint-cutting milling mechanism 8 is placed in needs broken
Concrete road surface 12 on cut out groove in advance, increase the freedom degree of concrete road surface 12, groove cuts out rear joint-cutting milling mechanism 8
On left side milling roller 8-1 and right side milling roller 8-3 act on concrete road surface 12 and keep concrete road surface 12 broken, cutting
While stitching the work of milling mechanism 8, ultrasonic wave air atomizer spray nozzle 13 generates depositing dust and is sprayed, and improves operation and air environment, cold
But nozzle 14 generates flow action and cools down in joint-cutting blade 8-2 to it；Cooling nozzles 14 stop working after the completion of joint-cutting, coagulation
Soil surface 12 is after joint-cutting milling mechanism 8 is broken, and mechanical arm 2 drives scraper bowl 10 to remove concrete slag and ditching, later ultrasonic wave
Air atomizer spray nozzle 13 also stops working.Concrete road surface 12 with high hardness can be used with multiple joint-cutting blade 8-2's
Joint-cutting milling mechanism 8 can produce multiple grooves, form multiple scope of freedoms, more preferable to the attenuation of concrete road surface 12.
The above is only presently preferred embodiments of the present invention, not does limitation in any form to the present invention, it is all according to
According to technical spirit of the invention, any simple modification and same variation are made to above embodiments, each fall within guarantor of the invention
Within the scope of shield.
