As a kind of improvement of the utility model, the booster pump and fresh water pump are centrifugal pump, and fracturing pump is plunger pump.
As a kind of improvement of the utility model, agitating device is equipped with inside the blending tank assembly.
As a kind of improvement of the utility model, the diesel engine and transmission system are equipped with shield, to play rain-proof, preventDirt, noise control, the anti-effect pounded etc..
The utility model has the following beneficial effects: the function of its fracturing unit truck and fracturing blender truck is combined into one, on one deviceThe functions such as sediment transport, mixing, pumping are completed, the number of units of construction operation equipment can be reduced, mountain area and area stenosis are located at for well siteOccasion, can reduce scene Construction traffic (reducing cost), put convenient for vehicle, more meet Oil Field job requirements andHabit.Vehicle is rationally distributed, compact-sized, easy to operate, and outer dimension, axle load etc. are in addition to meeting standard GB/T 1589Outside the requirement of " automobile, trailer and truck combination contour dimension, axle load and quality limit value ", by by special-purpose member (such as fracturing pump,Blending tank assembly, auger assembly etc.) it is arranged on the longitudinal centre line of platen, the stability of vehicle is improved, state is complied withThe requirement of 4.6 sections " roll stability and parking angle of stability " in family standard GB7258 " automobile safety running technology condition ", sideJust user settles, and expands application places.

Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginningSame or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginsengThe embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and cannot be construed to the utility modelLimitation.
It should be noted that the positional terms such as upper and lower, forward and backward in the utility model embodiment, are only relatively general each otherIt reads or be to refer to the normal operating condition of product, and should not be regarded as restrictive.
In Fig. 1 and Fig. 2, a kind of pressure break fracturing blender truck is mainly fixed on by chassis 1, using U-bolt the One On The ChassisPlaten 10, diesel engine 3, the hydraulic transmission box 5 being connected with 3 power output end of diesel engine, passes through transmission system (such as at radiator 2Transmission shaft etc.) 12 fracturing pump 7, the internal blending tanks for being equipped with agitating device that are connected with 5 power output end of hydraulic transmission box are totalIt is formed at 8 and auger assembly 9.The effect of auger assembly 9 mainly conveying quartz sand is into blending tank assembly 8.The water of diesel engine 3,The lubricating oil of machine oil, the lubricating oil of fuel oil and fracturing pump 7 and hydraulic transmission box 5 passes through radiator 2 and carries out air cooling way cooling.Wherein, radiator 2, diesel engine 3, hydraulic transmission box 4, fracturing pump 7, blending tank assembly 8 and auger assembly 9 are along the longitudinal direction of platen 10Center line is sequentially arranged in from front to back on platen 10, and hydraulic oil container 11 is equipped on the platen 10 of 3 side of diesel engine, anotherSide is equipped with electric cabinet 4, and the platen 10 of 8 side of blending tank assembly is equipped with the high pressure being connected with 7 fluid power output end of fracturing pumpManifold 16, the platen 10 of the other side are equipped with that be connected with 8 upper inlet of blending tank assembly dry adds system 13 and liquid adds and isSystem 15 is equipped with the fresh water pump 6 being connected with 8 bottom liquid inlet mouth of blending tank assembly below the platen 10 of 10 middle part side of platen, withHigh pressure pipe joint 16 is equipped with the booster pump 14 being connected with 8 liquid outlet of blending tank assembly below ipsilateral 10 tail portion of platen.Above-mentioned increasingPress pump 14 and fresh water pump 6 are centrifugal pump, and fracturing pump 7 is three-cylinder plunger pump, and diesel engine 3 and transmission system 12 have been equipped with anti-Rain, dust-proof, noise control, the shield of anti-the effects of pounding.Fresh water pump 6, booster pump 14, auger assembly 9, it is dry add system 13, liquid adds system15 are driven by the hydraulic pump of 4 power taking mouth of hydraulic transmission box installation；The starting of diesel engine 3 stops, the shift of hydraulic transmission box 5,Auger assembly 9, it is dry add system 13, liquid adds the control of system 15 and realizes in electric cabinet 4.
