Description

TECHNICAL FIELD

[0001] The utility model relates to a tractor pedal type fuel tank belongs to tractor technical field. BACKGROUND

[0002] As important mechanical equipment of agricultural production, the design of the fuel tank of the tractor is of great significance for improving work efficiency, safety and fuel economy.

[0003] The traditional tractor fuel tank is mostly an independent externally hung tank body, only has the function of storing fuel, occupies extra space in the overall design of the tractor, and the capacity of the fuel tank is limited, which cannot meet the needs of long-time operation. Especially, the fixed position of the fuel tank is not conducive to the refueling operation of the tractor driver; the single fuel tank shape is not convenient for cleaning and maintenance.

[0004] With the improvement of agricultural mechanization and the increasing demand for tractor operation convenience and multifunctionality, the pedal type fuel tank can meet the fuel storage needs, optimize space utilization and improve operation experience. The operator can climb onto the cab with the help of the steps on the fuel tank. However, the fuel tank is placed at the bottom of the whole machine frame, and due to the inertia force, the fuel in the fuel tank deviates from the oil suction port side when the fuel tank has less fuel, the whole machine is in an inclined working state or rapid steering, and the oil suction port cannot suck oil, which causes the engine to stop working. SUMMARY

[0005] The utility model aims at providing a tractor pedal type fuel tank which can ensure smooth fuel flow, has high integration degree and reliable installation.

[0006] The technical scheme to achieve the above-mentioned purpose of the utility model is: a tractor pedal type fuel tank, comprising a pedal tank, a step is arranged on the pedal tank, characterized in that:

[0007] An oil filler port, an oil outlet port, an oil return port and a sensor mounting hole are arranged on the top plate of the pedal tank, an oil quantity sensor is mounted in the sensor mounting hole, an emptying port for connecting with a breather is further arranged on the top plate of the pedal tank, and a recessed oil groove is arranged on the bottom plate of the pedal tank.

[0008] The pedal fuel tank has a groove on its top plate on one side of the step for mounting an air filter bracket. At least two raised air filter bracket seats are located on the top plate at the groove, each with a threaded blind hole. A urea tank is installed below the groove in the pedal fuel tank, with its filling port located at the front of the pedal fuel tank. The pedal fuel tank has a protruding portion on the rear side of the step, with corresponding recessed fixing grooves on the front and back plates of the protruding portion.

[0009] This invention features a fuel filler neck, fuel outlet, fuel return neck, and sensor mounting hole on the top plate of the pedal fuel tank. The fuel outlet and fuel return neck are connected to the fuel supply system via fuel pipes. The bottom plate of the fuel tank has a recessed fuel groove, allowing the fuel suction port of the fuel suction pipe to be positioned within this groove. This ensures efficient fuel utilization and prevents the fuel suction port from remaining within the groove even when the fuel tank is tilted or undergoes a sharp turn, guaranteeing smooth fuel flow and solving the problem of engine stalling due to insufficient fuel intake. The invention also includes a vent on the pedal fuel tank to expel air from the tank to the breather, ensuring reliable refueling and improving fuel supply reliability. Finally, this invention integrates a urea tank into the pedal fuel tank, improving overall space utilization. This invention features a recessed section on the top plate of the fuel tank, allowing the air filter bracket to be installed on the air filter bracket seat within the recessed section. This integrates the air filter into the pedal-mounted fuel tank, resulting in a high degree of integration. This tractor pedal-mounted fuel tank of this invention increases fuel tank capacity while making efficient use of limited space, thereby meeting the operational needs of tractors.
