The utility model is the technological scheme realizing its object is such: construct a kind of engineering machinery urea tank, comprise tank body and filling ABAP Adapter, also comprise filling extension tube in addition, described filling extension tube is sebific duct, its one end is fixedly connected with the filler on urea tank tank body, the other end is fixedly connected with described filling ABAP Adapter, and filling ABAP Adapter is connected with the mounting plate be fixed described filling ABAP Adapter.In the utility model, by arranging filling extension tube between tank body and filling ABAP Adapter, thus overcome the narrow limitation of urea tank installing space on complete machine, by filling extension tube, filling ABAP Adapter can be arranged on the position of convenient filling, thus provide convenient for urea liquid of annotating in urea tank.
In above-mentioned engineering machinery urea tank, the end that filling extension tube is connected with filling ABAP Adapter is provided with corrosion resistant rigid connecting and takes over, one end sleeve of described rigid connecting adapter is in described filling extension tube, one end has the flange of outwards upset in addition, described filling ABAP Adapter sleeve is in described rigid connecting adapter, described filling ABAP Adapter is exposed the outside part of rigid connecting adapter and is had radial outstanding assembly department, be bolted between described assembly department and described mounting plate, the flange of described rigid connecting adapter is clamped between the assembly department of described mounting plate and filling ABAP Adapter.
In above-mentioned engineering machinery urea tank, between the flange of described rigid connecting adapter and the assembly department of filling ABAP Adapter, be provided with seal rubber pad.
In above-mentioned engineering machinery urea tank, one end of described mounting plate be provided with for rigid connecting adapter through circular hole, and this end is fixedly connected with described filling ABAP Adapter, and the other end has the fixing bolt of mounting plate.
In above-mentioned engineering machinery urea tank, the angle theta in the axis of described filling ABAP Adapter and substantially horizontal should meet: tag θ >=1/6;
In above-mentioned engineering machinery urea tank, the two ends of filling extension tube are respectively equipped with clip.
The beneficial effect that the utility model compared with prior art has: in the utility model, by arranging filling extension tube between tank body and filling ABAP Adapter, thus overcome the narrow limitation of urea tank installing space on complete machine, by filling extension tube, filling ABAP Adapter can be arranged on the position of convenient filling, thus provide convenient for urea liquid of annotating in urea tank.
Accompanying drawing explanation
The structural representation of Fig. 1 the utility model engineering machinery urea tank.
Fig. 2 the utility model engineering machinery partial enlarged drawing of urea tank filling end.
Component title and sequence number in figure:
Tank body 1, first clip 2, filling extension tube 3, second clip 4, end cap 5, rigid connecting adapter 6, seal rubber pad 7, filling ABAP Adapter 8, mounting plate 9, urea liquid drawing device 10, vehicle frame tailgate 11, fuel tank 12.
Embodiment
Below in conjunction with accompanying drawing, specific embodiments is described.
As shown in Figure 1 and Figure 2, the engineering machinery urea tank in the present embodiment is made up of with parts such as filling port part and end cap 5 etc. urea liquid tank body 1, filling extension tube 3, and the top of tank body is provided with urea liquid drawing device 10 and connecting pipeline.Filling extension tube 3 is sebific duct, and its one end is fixedly connected with the urea liquid filler on tank body 1 and is fixed by the first clip 2, and the other end is connected with filling port part and is fixed by the second clip 4.Filling end pieces comprises rigid connecting adapter 6, seal rubber pad 7, filling ABAP Adapter 8, mounting plate 9, rigid connecting adapter 6 is Stainless Steel Tube, its one end sleeve is in the end of filling extension tube 3, and use the second clip 4 to be fixed in the outside of filling extension tube 3, other one end of rigid connecting adapter 6 has outside upset, be similar to the flange of flange, filling ABAP Adapter 8 sleeve is in rigid connecting adapter 6, the part that filling ABAP Adapter 8 exposes rigid connecting adapter 6 outside has radial outstanding assembly department, be bolted between assembly department and mounting plate 9, the flange of rigid connecting adapter 6 is clamped between the assembly department of mounting plate 9 and filling ABAP Adapter 8.Seal rubber pad 7 is arranged between the flange of rigid connecting adapter 6 and the assembly department of filling ABAP Adapter 8.
One end of mounting plate 9 be provided with for rigid connecting adapter through circular hole, this end is fixedly connected with filling ABAP Adapter 8 by bolt, the other end has the fixing bolt of mounting plate, by fixing bolt, filling end is fixed on position complete machine being convenient to filling urea liquid.
In the present embodiment, filling extension tube 3 is made by the domestic EPDM material being applicable to urea liquid, and urea tank body 1 is provided by motor producer and matched with diesel engine, and filling ABAP Adapter 8 is the exclusive product of company of the U.S. (the special producer manufacturing urea tank).Filling ABAP Adapter 8 inside diameter size and magnetic patch and American-European urea filling gun port outside diameter Aided design, can prevent the mistake of diesel oil filling gun from using.In the U.S., diesel oil filling gun port outside diameter is greater than urea filling gun port, and the use of ABAP Adapter 8 of herein annotating effectively can prevent driver's being filled into diesel oil mistake in urea liquid liquid container.Filling ABAP Adapter 8 can not directly be connected with filling extension tube 3, and centre is connected by stainless steel rigid connecting adapter 6 transition of resistant to urea solution corrosion, between rigid connecting adapter 6 and filling ABAP Adapter 8, seal rubber pad 7 is housed, urea liquid seepage during to prevent from annotating.Finally connecting tube 6, rubber cushion 7 being combined with ABAP Adapter 8 with bolt is arranged on mounting plate 9, to be fixed on vehicle frame tailgate 11.
As shown in Figure 1, in the present embodiment, the filling port position of engineering machinery urea tank designs the tailstock place closer to complete machine, and the angle of inclination of the filling ABAP Adapter 8 of port is parallel with the filler on urea tank body 1, its inclination angle is 52 °, no matter this design is the state that urea liquid filing provision is also not universal at home, still proprietary abroad urea liquid supply station, can both obtain good operability and maintainability.Meanwhile, the design of the filler homonymy of urea liquid filler and diesel fuel tanks 12, under the state that diesel oil and the urea liquid ratio of filling are bordering on 1:1, is more conducive to the convenience of driver operation.
