Abstract
The fuel external-connected supply device for agricultural transport vehicle includes high-pressure fuel pump, fuel injection device and fine filter, the fine filter is connected with high-pressure fuel oil pump by means of fuel oil cupper pipe, the high-pressure fuel oil pump is connected with fuel injection device, said fuel injection device is connected with fine filter by means of returning copper pipe, between the external-connected fuel oil tank and fine filter a fuel oil delivery device and a fuel oil returning channel are connected, and the fuel oil delivery device is connected with power by means of belt wheel. After said invention is adopted, according to the designed requirements of agricultural transport vehicle the fuel oil tank can be enlarged, and can be placed on any place of vehicle body.
Description
One, technical field
The present invention relates to a kind of fluid delivery system, the oil supplying device that the external fuel oil supply system of particularly a kind of agricultural transportation vehicle uses.
Two, background technique
Its power of present agricultural transportation vehicle generally adopts single cylinder diesel, though the supporting fuel tank of single cylinder diesel is several times reformed, but restriction because of the diesel engine general arrangement, its fuel oil supply system be unable to do without self-flow type all the time, fuel tank still is placed on the diesel engine, because the restriction of fuel tank, vehicle is unreasonable when causing general arrangement, and causes the difficulty of single cylinder diesel maintenance.Agricultural transportation vehicle because the fuel tank volume of single cylinder diesel is little, the store oil amount often needs to refuel less, also need be equipped with oil drum when long-distance transportation in transportation process, bring inconvenience to transportation.
Three, summary of the invention
Can only be placed on single cylinder diesel top, the fuel tank volume can't strengthen, the vehicle design is restricted disadvantage in order to overcome existing agricultural transportation vehicle self-flow type oil supply system fuel tank, the invention provides a kind of agricultural transportation vehicle oil supplying device of forcing fuel feeding, adopt this device can make fuel tank be placed on car body arbitrarily Anywhere, as the crossbeam next door, can design the fuel tank size as required arbitrarily simultaneously.The technical solution adopted for the present invention to solve the technical problems comprises high pressure oil pump, oil sprayer, secondary filter, secondary filter is connected with high pressure oil pump by the oil transportation copper pipe, high pressure oil pump links to each other with oil sprayer by high-pressure oil pipe, oil sprayer is connected with secondary filter by the oil return copper pipe, be connected with oil delivering device and drainback passage between outer connected tank and the secondary filter, oil delivering device is connected with power by belt pulley.After adopting said structure, diesel powered is imported by belt pulley, belt pulley drives oil delivering device work, oil delivering device is transported to the oil of outer connected tank original oil supply system-secondary filter, high pressure oil pump and the oil sprayer of single cylinder diesel, the fuel oil of single cylinder diesel is guaranteed, unnecessary fuel oil is got back to outer connected tank by oil returning tube, when in single cylinder diesel oil starvation or the oil circuit air being arranged, just can't start, this moment, available hand pump was bought oil, allow secondary filter be full of deoil side by side air in the road of oil, get final product proper functioning.After adopting this programme, agricultural transportation vehicle can add large tank according to design, not joining in addition under the power situation, fuel tank is arranged on car body Anywhere, have simple and reasonable, install and use and keep in repair easily, advantages such as the store oil amount is big, the vehicle global design is convenient.
Four, description of drawings
Fig. 1 is first kind of embodiment structural representation of the present invention.
Fig. 2 is second kind of embodiment structural representation of the present invention.
Five, embodiment
Shown in Figure 1, first kind of specific embodiments for fuel external feeder for agricultural transportation vehicle of the present invention, it comprises high pressure oil pump 10, oil sprayer 12, the secondary filter 14 of original oil supply system, secondary filter 14 is connected with high pressure oil pump 10 by oil transportation copper pipe 16, high pressure oil pump 10 links to each other with oil sprayer 12 by high-pressure oil pipe 11, oil sprayer 12 is connected with secondary filter 14 by oil return copper pipe 13, is connected with oil delivering device and drainback passage 15 between outer connected tank 1 and the secondary filter 14.Oil delivering device is made up of plunger pump assembly 6,6 imports of plunger pump assembly through fuel sucking pipe 4 and fuel supply line 5 with outside connected tank 1 be connected, outlet links to each other with secondary filter 14 through oil outlet tube 9, plunger pump assembly 6 is provided with hand pump 7, belt pulley 8 is fixed on the transmission shaft of plunger pump assembly 6, belt pulley 8 is connected with power by drivign belt, and fuel sucking pipe 4 imports are provided with strainer 2, and outer connected tank 1 is provided with oil filler 3 and fuel-quantity transducer 18.
Shown in Figure 2, second kind of specific embodiments for fuel external feeder for agricultural transportation vehicle of the present invention, it comprises the high pressure oil pump 10 of original oil supply system, oil sprayer 12, secondary filter 14, secondary filter 14 is connected with high pressure oil pump 10 by oil transportation copper pipe 16, high pressure oil pump 10 links to each other with oil sprayer 12 by high-pressure oil pipe 11, oil sprayer 12 is connected with secondary filter 14 by oil return copper pipe 13, be connected with oil delivering device and drainback passage 15 between outer connected tank 1 and the secondary filter 14, oil delivering device is made up of gear pump assembly 26 and hand pump 7,26 imports of gear pump assembly through fuel sucking pipe 4 and fuel supply line 5 with outside connected tank 1 be connected, outlet links to each other with secondary filter 14 through oil outlet tube 9, hand pump 7 is connected between secondary filter 14 and the drainback passage 15, link to each other by return tube 19 between secondary filter 14 and the hand pump 7, be parallel with selector valve on the hand pump 7, belt pulley 8 is fixed on the transmission shaft of gear pump assembly 26, and belt pulley 8 is connected with power by drivign belt.Outer connected tank 1 is provided with intubate 20, and intubate 20 reaches the bottom of outer connected tank 1, and drainback passage 15 is connected intubate 20; Fuel sucking pipe 4 imports are provided with strainer 2, and outer connected tank 1 is provided with oil filler 3 and fuel-quantity transducer 18.
Certainly, the hand pump 7 of second kind of embodiment also can not be connected between secondary filter 14 and the oil returning tube 15, can realize identical functions equally but be connected in parallel with gear pump assembly 26, during this kind scheme, and can be without intubate 20 and selector valve.
When installing and using, the corresponding installation of oil delivering device with single cylinder diesel, outer connected tank 1 can be installed in the arbitrary position of car body.When single cylinder diesel turns round, diesel powered drives oil delivering device work by belt pulley 8, oil delivering device is transported to the oil of outer connected tank 1 original oil supply system-secondary filter 14, high pressure oil pump 10 and the oil sprayer 12 of single cylinder diesel, the fuel oil of single cylinder diesel is guaranteed, and unnecessary fuel oil is got back to outer connected tank 1 by oil returning tube 15.When in single cylinder diesel oil starvation or the oil circuit air being arranged, transport vehicle just can't start, and this moment, available hand pump 7 was bought oil, and allows secondary filter 14 be full of deoil side by side air in the road of oil, gets final product proper functioning.
