Background technology
Mine truck running environment is severe, is chronically at many dirt, humidity, dither, the operation of high intensity load running
In environment.According to mining production mission requirements：One many people of mine truck is used alternatingly, and filling oil cover 11 is disliked for a long time in mine truck
Easily caused during bad environment work loss, deformed damaged and it is poorly sealed situations such as, debris be easily mixed into fuel tank pollution fuel oil,
Fuel oil cleannes are destroyed, influence engine performance is normally played, and causes mine car automobile engine failure rate of machinery to remain high.Make
Mine user adds substantial amounts of human and material resources, financial resources and vehicle is maintained, and the mine user equipment rate of attendance is obtained not
To guarantee.
As shown in figure 1, being the structure decomposition figure of mine truck fuel tank in the prior art.
Now simple with the cover structure for fuel tank of mine truck, function is single, such as 100 tons of present mine truck main engine plants production
Mechanical wheel mine truck, included using the structure of fuel tank cap：Filling oil cover 11, sealing gasket 12, sealing ring 13, coarse filter 14, card
Lock 15, fuel tank cap is arranged on oil filler 16.
The non-normal consumption problem of fuel oil is on mine than more prominent.The oil filler 16 of present mine truck main engine plants fuel tank
To be through-type, simple in construction, fuel tank cap is without locking system.Mine car vehicle fuel can be removed, and cause mine user nonproductive
The resources loss and cost increase of purposes.
Sealing uses screw thread pressurization pad 12, sealing ring 13 to seal, and mine user is not easy to screw in,
Easily cause it is poorly sealed, oil filler 16 nearby have fuel oil spilling, there is certain potential safety hazard；Oscillation ring in mine truck traveling
Border easily makes filling oil cover 11 come off loss, and the dynamics of screwing crosses conference and causes the secondary opening of filling oil cover 11 difficult；Due to oil filler 16
Screw thread does not possess prosthetic, in the case of long-term use, and the screw thread mouth of oil filler 16 is fragile.
The content of the invention
Technical problem solved by the invention is to provide a kind of mine truck fuel tank with dust-proof anti-theft anti-drop function,
Simultaneously there is locking, antitheft and anti-dropout function.
Technical scheme is as follows：
A kind of mine truck fuel tank with dust-proof anti-theft anti-drop function, including tank filling path, fuel tank cap, fuel tank

Oily path is provided with edge in end, and fuel tank cap is arranged at edge.
Further：The mode being connected selects shaft connecting mode or gear connecting way.
Further：In shaft connecting mode, locking system is connected with lock core by rotating shaft.
Further：The back side of lid is provided with limiter, and limiter is used for the slewing area for limiting locking system.
Further：Function overhead gage entirety semicircular in shape, is provided with first through hole, circle centre position, which is provided with overhead gage, to be opened thereon
Mouthful.
Further：Semicircular baffle entirety semicircular in shape, is provided with the second through hole thereon.
Further：Full baffle plate is integrally rounded, and third through-hole is provided with thereon.
Further：Edge is overall in a ring, and locking opening is provided with inside edge.
Compared with prior art, the technology of the present invention effect includes：
Fuel tank cap and oil filler coordinate, at the same there is locking, antitheft and anti-dropout function.The novel designs of fuel tank cap,
The change of tank filling path at oil filler, is embodied in and guard against theft oil and convenient oiling unites two into one.First, at function overhead gage
Overhead gage opening improve oiling convenience, nozzle directly can be stuck at overhead gage opening by staff, it is no longer necessary to
Personnel grip nozzle for a long time, reduce working strength, improve operating efficiency.Secondly, function overhead gage, semicircle gear
The use of plate and full baffle plate so that tank filling path becomes serpentine from former " one " font, adds innermost full baffle plate
Closing, has prevented on the premise of normal refuel is not influenceed and thoroughly the abnormal loss of fuel tank intermediate fuel oil, from technological layer solution
Fuel oil of having determined is stolen.
