The dynamical system of carrier vehicle drives, and may also connect to external power source), from filtering tank 19, cyclone separator 18, storage tank 26, arm
Air is aspirated in the conductive channel that pipe 17, excavating head 16 are formed, finally in arm pipe 17, excavating head 16 and near excavating head 16
Form high speed negative pressure gas flow.High-speed jet, the closely knit object of cutting and crushing are ejected to rolled base by high-pressure water shot streaming system 3
Material, forming it into particle or block material, (high-pressure water shot streaming system 3 can be driven by the dynamical system of carrier loader, may also connect to
External power source).Operator manipulates excavating head 16 close to particle or block material, when high-speed flow flow velocity is greater than particle or bulk
When the floating velocity of material, high-speed flow drives particle or block material to flow and be ultimately inhaled in storage tank 26 with air-flow.By
Larger in 26 sectional area of storage tank, air-flow velocity is lower, and most of particle or block material sink to storing under gravity
26 bottom of tank.Small particle and vapor separate major part by cyclone separator 18 with air-flow inflow cyclone separator 18
Small particle and vapor, subsequent air-flow enter filtering tank 19, form clean air by the filtering of filtering tank 19 and enter four-way and change
To ball valve 20, strength generating device 21, muffler 22, it is ultimately discharged into atmosphere.
(2) pressurization backfilling working mode.
Four-way reversing globe valve 20 is operated, pressing position is at.Suction inlet 28, lower suction inlet 31 in closing；Connector is connected
27, discharge gate 32.At this point, 21 air entry of strength generating device and muffler 22 are connected, 21 row of strength generating device
Port and filtering tank 19 are connected.The strength generating device 21 is used as pressure-generating device, and the muffler 22 disappears as air-breathing
Sound device.The strength generating device 21 operates under transmission device drive, from 22 air-breathing of muffler, passes through four-way reversing globe valve
20, filtering tank 19, cyclone separator 18 are vented to storage tank 26 and pressurize, under the action of internal pressure, storage in storage tank 26
Solidliquid mixture from discharge gate 32 squeeze out, by drainage conduit 24 to excavated position backfill.
This vacuum is excavated vehicle and can be accurately positioned, minimally invasive to ground to excavate (excavating aperture small arrive diameter 200mm), ring
Protect not fugitive dust；In digging process, pipeline will not be injured；Pipeline can also be crossed and empty excavation downwards, facilitate pipeline maintainance；It utilizes
High-pressure water shot streaming system cutting and crushing rolled base forms particle or block material, defeated by aspirating using Pneumatic Conveying Technology
Air formation high speed negative pressure gas flow in system is sent to be conveyed；It is low to convey negative pressure, reduces to strength generating device vacuum performance
Requirement；The limitation of vacuum pressure is breached, suction capactity is stronger；It can be sent out by changing reversing arrangement position using strength
Generating apparatus pressurizes to aggregate-storing system, and the solidliquid mixture of aggregate-storing system storage is squeezed out from discharge gate, backfills to position has been excavated,
The wasting of resources is avoided, operation is more efficient.
In short, the foregoing is merely presently preferred embodiments of the present invention, it is all according to equalization made by scope of the present invention patent
Variation and modification, shall all be covered by the patent of the invention.
