The utility model has the advantages that a deflation via is arranged on the pipe wall of an oil channel, the oil channel comprises the hollow bolt and the hollow joint, and the deflation via is connected with a bleeder pipe.
Description
Technical field
The utility model relates to the external oil-way system of agricultural vehicle motor, particularly a kind of automatic deflation oil pipe assembly.
Background technique
Be connected oil-way system between existing agricultural vehicle motor and the filter cleaner, what its oil pipe pipeline adopted is crooked shape metal tube, is commonly called as the S pipe, and the two ends of S pipe are connected with hollow joint respectively, generally are to weld by brazing; The hollow joint that connects motor one end is sealedly and fixedly connected by hollow bolt and motor filler opening; Bar portion at hollow bolt is provided with the bolt oilhole that is communicated with hollow joint oil duct and hollow bolt oil duct.All the time, such agricultural vehicle oil-way system structure causes many inconvenience because have inevitable air-resistance phenomenon in the oil pipe to the user.When in the oil pipe air being arranged, oil circuit is obstructed, at this moment must screw hollow bolt the bolt oilhole is exposed, thereby deflate, and has put up to there being oil to flow out just definite gas, tightens hollow bolt then.Because the spatial position in agricultural vehicle between motor and the filter cleaner is not easy to the oil pipe bleed air operation very much, causes operate miss easily, and time-consuming.
The model utility content
The utility model is at the above-mentioned defective that exists in the prior art, and providing a kind of can exit to eliminate the automatic deflation oil pipe assembly of air-resistance phenomenon to oil pipe at any time.
The technical solution of the utility model is as follows:
Automatic deflation oil pipe assembly, comprise oil pipe, be connected in the hollow joint of this oil pipe, and the hollow bolt that hollow joint is fixedly connected on the motor filler opening, it is characterized in that: the oil duct tube wall that described hollow bolt and described hollow joint are formed is provided with the venting through hole, and this venting through hole is connected with exhaust tube.
Described venting through hole is arranged at the head of described hollow bolt.
Described venting through hole is arranged at the bar portion or the head of described hollow joint.
Described exhaust tube is communicated with the fuel tank inner chamber by fuel tank top away from an end of described venting through hole.
Described oil pipe adopts engineering plastics.
Described hollow joint adopts engineering plastics.
The bar portion of described hollow joint is for upwarping shape, and described oil pipe is straight shape, describedly upwarps shape bar portion and described straight shape oil pipe is suitable.
Technique effect of the present utility model is as follows:
Because the oil duct tube wall that the utility model hollow bolt and hollow joint are formed is provided with the venting through hole, and be provided with the exhaust tube that is connected with the through hole of exitting, make the air in the oil pipe under the effect of oil pressure difference, discharge from exhaust tube automatically, so just needn't re-use the venting of bolt oilhole, thereby must screw the inconvenience of hollow bolt when having avoided venting with instrument, can exit to eliminate air-resistance phenomenon to oil pipe at any time by special-purpose exhaust tube passage.
Because the venting through hole both can be arranged at the head of hollow bolt, can be arranged at the bar portion or the head of hollow joint again, can keep original oil-way system structure constant fully like this, illustrate that the invention is a technical solution that is suitable for practicality.
Because exhaust tube can be communicated with the fuel tank inner chamber by fuel tank top away from an end of described venting through hole, can prevent effectively during venting that oil from sputtering out.So both can realize the function of automatic deflation, exhaust tube can be controlled at suitable height again, and can avoid exhaust tube to stop up, and keep the cleaning of exhaust tube unimpeded.
Make oil pipe, hollow joint owing to adopt engineering plastics, not only can save a large amount of metallic material, and be convenient to the improvement of shape and structure, therefore, be provided with straight shape oil pipe in the technological scheme, and be equipped with the hollow joint that bar portion upwarps, simplified the S shape labyrinth of oil pipe so first, second shortened the length of oil pipe, thereby saved oil pipe assembly taking up room in agricultural vehicle widely, it is also more convenient to install simultaneously, operate, keep in repair and change.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model automatic deflation oil pipe assembly is by the hollow joint 8 of filter cleaner, oil pipe 7, hollow joint 3, hollow bolt 10 and exhaust tube 13 are formed, its annexation is: the upper end of the oil pipe 7 hollow joint 8 of filter cleaner that is tightly connected, the lower end of the oil pipe 7 hollow joint 3 that is tightly connected, hollow joint 3 is fastened and connected by the filler opening of hollow bolt 10 with motor 1, inner for connecting oil circuit, the i.e. oil duct of the hollow joint of filter cleaner, the oil duct of oil pipe 7, the oil duct 5 of hollow connector rod portion 6, hollow joint oil groove 2, bolt oilhole 4 and hollow bolt oil duct 9 communicate with each other; Venting through hole 11 is opened in the head of hollow bolt 10, and an end communicates with hollow bolt oil duct 9, and the other end is communicated with exhaust tube 13 by venting through hole joint 12.
As shown in Figure 2, venting through hole 11 is opened in the bar portion 6 of hollow joint 3, and venting through hole joint 12 and hollow joint 3 have adopted the design concept of integrated making.
Indicated as Fig. 1 and Fig. 2, as long as the through hole 11 of will exitting is arranged on the oil duct tube wall of described hollow bolt 10 and described hollow joint 3 compositions, can both realize same technical functionality.
Venting principle of the present utility model is: hang between the fuel tank pasta of motor filler opening top and the motor filler opening and exist pressure difference, do not have air in oil circuit, when promptly air-resistance phenomenon not taking place, oil will be taken advantage of a situation and be descended; Air is arranged in oil circuit, owing to offer the venting through hole being positioned on the oil duct tube wall of an end that the oil pipe lower end promptly connects the motor filler opening, this becomes open oil-way system with regard to the oil-way system that makes sealing originally, and gas can be discharged along the venting through hole under action of pressure naturally.The venting through hole connects exhaust tube, so not only can emit the air in the oil pipe but also can prevent overflowing of oil.
Fig. 3 has shown the relative installation of motor 1, oil pipe assembly 14 and fuel tank 16.During oiling, oil gun inserts from tank filler 17 and refuels, and air pipe 18 is used for decomposing the air-flow of fuel tank 16 deaerations when refueling.After the oiling, oil is by in filter cleaner 15 and oil pipe assembly 14 inflow engines 1.Oil pipe assembly 14 comprises oil pipe 7 that is communicated with filter cleaner 15 and the exhaust tube 13 that is communicated with fuel tank 16 by oil filler 17.
Obviously, adopt engineering plastics to make the component of oil pipe assembly, can produce form parts easily, thereby change the shape and structure of existing agricultural vehicle oil pipe assembly.The bar portion of hollow joint 3 can be designed as and upwarps shape, oil pipe 7 can be designed as straight shape, describedly upwarp shape bar portion and described straight shape oil pipe is suitable, simplified the S shape labyrinth of oil pipe so first, second shortened the length of oil pipe, thereby saved oil pipe assembly taking up room in agricultural vehicle widely, it is also more convenient to install simultaneously, operate, keep in repair and change.
The above only is a preferred implementation of the present utility model.Should be understood that; for a person skilled in the art, based on the same principle of invention of the utility model, can also make some modification and improvement; and the technical program is in the application in other similar fields, but these all fall into protection domain of the present utility model.
