Detailed Description

The core of the utility model is to provide a fuel feeding bellytank, outwards export fluid more easily under the condition that fluid volume is few.

In order to make those skilled in the art better understand the technical solution of the present invention, the fuel supply drop tank of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1A, in order to provide the structure of a specific embodiment of the fuel supply drop tank of the present invention, fig. 1B is a cross-sectional view along the direction K-K in fig. 1A; the utility model discloses a fuel feeding bellytank is including fixing bellytank 1 in the main tank, and the inside splendid attire fluid that is used for of bellytank, and the cross-sectional area of bellytank is less than the main tank, and the fluid of the same volume highly is higher than in the main tank in the bellytank, and the top of bellytank is opened, and the oil pipe of inhaling of oil pump stretches into in the bellytank, can outwards take the fluid in the bellytank out.

An oil inlet pipeline 2 is arranged in the main oil tank, the oil inlet pipeline 2 comprises a horizontal section 21 and a vertical section 22, and the horizontal section 21 and the vertical section 22 are communicated with each other; the horizontal section 21 is close to the inner bottom of the main oil tank, the horizontal section 21 is immersed below the oil level, the bottom surface of the horizontal section 21 is provided with an oil supplementing port 23 for oil inlet, and oil in the main oil tank can enter the oil inlet pipeline 2 through the oil supplementing port 23.

The horizontal section 21 is provided with the jet pump 3, the jet pump 3 is used for pumping oil which flows back from the working equipment, the jet pump 3 increases the flowing speed of the oil, the oil sprayed from the jet pump 3 forms negative pressure, the oil in the main oil tank enters the oil inlet pipeline 2 through the oil supplementing port 23 under the action of the negative pressure, and the oil in the main oil tank and the oil sprayed from the jet pump 3 are merged and flow to realize injection; the combined oil enters the secondary oil tank through the vertical section 22, and is pumped out of the secondary oil tank.

The cross section area of the auxiliary oil tank is smaller than that of the main oil tank, and the auxiliary oil tank has a higher height than that of the main oil tank under the condition of only a small amount of oil, so that the oil pump can suck the oil more easily; the auxiliary oil tank plays a role in gathering oil in the main oil tank and intensively pumping the oil outwards.

On the basis of the scheme, the auxiliary oil tank 1 is arranged on the inner bottom surface of the main oil tank, and the auxiliary oil tank 1 is supported by the bottom surface of the main oil tank; the bottom of the auxiliary oil tank 1 protrudes downwards to form a foot pad 4, and the foot pad 4 enables a gap to be reserved between the bottom surface of the auxiliary oil tank 1 and the main oil tank. Because the bottom of the auxiliary oil tank 1 is a complete sealing structure, oil cannot leak downwards.

As shown in fig. 2A, which is a partial enlarged view of a portion a in fig. 1A, a connection column is arranged at the bottom of the secondary fuel tank 1 in a downward protruding manner, a foot pad 4 is sleeved on the connection column, the foot pad 4 is in interference fit with the secondary fuel tank 1, and the foot pad 4 can be conveniently installed and removed; the foot pad 4 is made of rubber materials, and shock resistance between the auxiliary oil tank 1 and the main oil tank is avoided.

Further, the utility model discloses set up main oil inlet 11 in the bottom of bellytank 1, fluid accessible main oil inlet 11 in the bellytank directly enters into inside. A mushroom diaphragm 5 is arranged on the inner side of the bottom surface of the auxiliary oil tank 1, the mushroom diaphragm 5 is provided with a rubber film capable of sealing and covering the main oil inlet 11, as shown in fig. 2B, a partial enlarged view of a part B in fig. 1A is shown, and oil liquid flows in the direction shown by an arrow; when the oil pump sucks oil from the auxiliary oil tank, the rubber membrane of the mushroom membrane 5 is lifted upwards, so that the main oil inlet 11 is communicated, and oil in the main oil tank enters; when the oil pump stops pumping oil, the rubber membrane of the mushroom diaphragm 5 rebounds and resets to cover the main oil inlet 11, the main oil inlet 11 is blocked, oil cannot enter, and meanwhile, the mushroom diaphragm 5 stops the oil in the auxiliary oil tank from reversely flowing into the main oil tank.

The auxiliary oil tank 1 has no other part communicated with the outside except the main oil inlet 11, so that the possibility of oil leakage is reduced to the maximum extent.

Further, the utility model discloses an oil inlet pipe 2 sets up in the inside of bellytank 1, nevertheless oil inlet pipe 2 and bellytank 1's inner space relatively keeps apart, and oil inlet pipe 2 can only be through the top of vertical section 22 to bellytank transport fluid.

The oil inlet pipeline 2 further comprises an oil return section 24 which is vertically arranged, the top end of the oil return section 24 is connected with a working device, the bottom end of the oil return section is in butt joint with the horizontal section 21, an arrow in fig. 2B indicates the flowing direction of oil, the top end of the oil return section 24 is connected with the oil return pipeline of the working device, the oil tank enters the horizontal section 21 from the oil return section 24, the oil tank is sprayed out from the injection pump 3 in the horizontal section 21 in an accelerating mode, the oil is sucked into the oil supplementing port 23, and the oil flowing at a high speed is discharged into the auxiliary oil tank from.
