Description

Technical Field

[0001] The utility model relates to the technical field of oil tanks, in particular to a one-way valve, an oil supply device and a tractor. Background Art

[0002] For small and medium-power non-road agricultural machinery, due to the space limitations of the overall machine structure, a single fuel tank cannot usually meet the needs of long-term operation. Usually, two fuel tanks are arranged on both sides of the chassis of the whole machine. The two fuel tanks are then connected in series through the oil pipes at the bottom of the fuel tanks to increase the capacity of the fuel tanks, so as to adapt to longer-term operation.

[0003] The operating conditions of small and medium-power agricultural machinery are complex, and they usually operate on hilly slopes. Due to the uneven ground, the whole machine will tilt when working, causing the fuel in the higher fuel tank of the left and right series-connected fuel tanks to flow into the lower fuel tank. Since the suction pipe in the fuel tank is only arranged in one fuel tank, in actual operation, there will always be a situation where the fuel tank where the suction pipe is located is at a high position. The fuel flows into the other fuel tank, causing the liquid level of the suction pipe to lower, which will cause the suction pipe to fail to absorb fuel and cause the engine to stall.

The rotating baffle has a rotating shaft, one side of which is flat and can fit and contact with the rotating fixed seat to play a sealing role.

[0011] Furthermore, a notch is provided at the bottom of the rotating baffle.

[0030] The beneficial effect of adopting the technical solution of the utility model is as follows: by designing a one-way valve with a connecting shell, an elastic component, a rotating baffle, and a rotating fixed seat, the one-way valve can be arranged on the connecting pipe at the bottom of the two fuel tanks, and the fuel flows in the fuel tank without the oil suction pipe. The fuel can be supplied to the fuel tank with the oil suction pipe according to the oil height. In this way, when the whole machine is operating on a slope, due to the side tilt of the whole machine, when the fuel tank with the oil suction pipe installed is in a high position, the one-way valve basically limits the fuel flow to the low-position fuel tank, thereby ensuring that the oil suction pipe can maintain a certain fuel volume and can absorb fuel, thereby improving the utilization rate of the fuel and effectively increasing the working time.

[0031] like Figure 1 and Figure 2 As shown, further, the connection housing 11 is a circular structure, and the outer side walls at both ends of the connection housing 11 are provided with anti-drop structures 16 to prevent the pipeline from falling off.

[0041] A one-way valve provided in an embodiment of the utility model can be a new type of fuel one-way valve, which is arranged on a connecting pipe at the bottom of two fuel tanks. The flow direction of the fuel is that the fuel in the fuel tank without an oil suction pipe can be supplied to the fuel tank with an oil suction pipe according to the oil height. In this way, when the whole machine is operating on a slope, due to the side tilt of the whole machine, when the fuel tank with the oil suction pipe installed is in a high position, the new type of fuel one-way valve (one-way valve) basically limits the flow of fuel to the low-position fuel tank, thereby ensuring that the oil suction pipe can maintain a certain fuel volume and can absorb fuel, thereby improving the utilization rate of the fuel and effectively increasing the working time.

[0042] The one-way valve 4 mainly comprises: a connecting housing 11, an elastic component 12, a rotating shaft 13, a rotating baffle 14, and a rotating fixed seat 15; in the one-way valve 4:

[0043] The connecting shell 11 is a circular structure. To ensure that the connecting pipe 6 does not fall out, the two outer ends of the shell (connecting shell 11) are provided with anti-falling structures 16 on both sides.

[0045] The rotating shaft 13 connects the rotating baffle 14 and the rotating fixed seat 15 and is also used as the rotating shaft of the elastic component 12;

[0046] The rotating baffle 14 has a rotating shaft 13, one side of which is flat and can be in contact with the rotating fixed seat 15 to play a sealing role, and a small gap 17 is designed at the bottom so that a smaller gap is left after being in contact with the rotating fixed seat 15;

[0047] The rotating fixing seat 15 is used to facilitate the installation of the rotating shaft 13 , the elastic component 12 and the rotating baffle 14 and then fix them to the connecting housing 11 .

[0048] like Figure 3 As shown, in addition, the utility model also provides a fuel supply device, including a one-way valve 4 as described in any one of the above items, and also includes: a first fuel tank 1, a second fuel tank 2, an oil suction pipe 3, and a connecting pipe 5, the first fuel tank 1 is connected to the second fuel tank 2 through the connecting pipe 6, the one-way valve 4 is installed on the connecting pipe 6, and the oil suction pipe 3 is connected to the first fuel tank 1.

[0049] The beneficial effect of adopting the technical solution of the utility model is as follows: by designing a one-way valve with a connecting shell, an elastic component, a rotating baffle, and a rotating fixed seat, the one-way valve can be arranged on the connecting pipe at the bottom of the two fuel tanks, and the fuel flows in the fuel tank without the oil suction pipe. The fuel can be supplied to the fuel tank with the oil suction pipe according to the oil height. In this way, when the whole machine is operating on a slope, due to the side tilt of the whole machine, when the fuel tank with the oil suction pipe installed is in a high position, the one-way valve basically limits the fuel flow to the low-position fuel tank, thereby ensuring that the oil suction pipe can maintain a certain fuel volume and can absorb fuel, thereby improving the utilization rate of the fuel and effectively increasing the working time.

[0050] Furthermore, the oil suction pipe 3 is connected to the engine 5 .

[0051] The beneficial effect of adopting the above further technical solution is that it is convenient to supply oil to the engine.

[0052] The embodiment of the utility model provides a fuel supply device, which can be a new fuel supply arrangement structure, mainly comprising: a first fuel tank 1, a second fuel tank 2, an oil suction pipe 3, an engine 5, a connecting pipe 6, and a one-way valve 4. The first fuel tank 1 and the second fuel tank 2 are arranged on both sides of the whole machine, respectively, the first fuel tank 1 supplies fuel to the engine 5 through the oil suction pipe 3, and the first fuel tank 1 and the second fuel tank 2 are connected to the one-way valve 4 through the connecting pipe 6.

[0053] A novel fuel supply arrangement structure (fuel supply device), comprising:

[0054] A first fuel tank 1 supplies fuel to an engine 5 via a fuel suction pipe 3;

[0055] The second fuel tank 2 is connected to the first fuel tank 1 through a connecting pipe 6 and a one-way valve 4;

[0056] The connecting pipe 6 connects the fuel tanks (the first fuel tank and the second fuel tank) and the one-way valve 4 .

[0057] A novel fuel supply arrangement structure (fuel supply device) and agricultural machinery (which may be a tractor) are specifically implemented as follows:

[0058] State 1: The whole machine is in a horizontal state, and the first fuel tank 1 and the second fuel tank 2 are kept horizontal

[0059] The first fuel tank 1 and the second fuel tank 2 are kept horizontal, and the one-way valve 4 is in a naturally closed state. At this time, the elastic component 12 in the one-way valve 4 is only fitted by the torsion spring pressure of the one-way valve 4, and the fuel in the two fuel tanks basically does not flow.

[0060] State 2: The whole machine is in a tilted state, and the first fuel tank 1 is higher than the second fuel tank 2

[0061] The first fuel tank 1 is higher than the second fuel tank 2, and the one-way valve 4 is in a closed state. The gravity of the fuel in the first fuel tank 1 will compress the rotating baffle 14, and only a very small part of the fuel will flow into the second fuel tank 2 from the small pores (notch) reserved between the rotating baffle 14 and the lower part of the rotating fixed seat 15, which can ensure that the oil suction pipe 3 in the first fuel tank 1 absorbs oil, and there will be no situation where the one-way valve is not installed, and the fuel quickly flows into the second fuel tank 2 and cannot absorb the oil, thereby ensuring the normal operation of the engine and improving work efficiency.

[0062] State 3: The whole machine is in a tilted state, and the first fuel tank 1 is lower than the second fuel tank 2

[0063] The first fuel tank 1 is lower than the second fuel tank 2. Under the action of the gravity of the fuel, the fuel in the second fuel tank 2 will push the one-way valve 4 to overcome the pressure of the elastic component 12 and make the rotating baffle 14 rotate and open. The fuel will flow from the second fuel tank 2 into the first fuel tank 1, which can ensure that the oil suction pipe 3 in the first fuel tank 1 can absorb oil, ensure the normal operation of the engine, and improve work efficiency.

[0064] A novel fuel supply arrangement structure (fuel supply device) and agricultural machinery (tractor) adopt a novel one-way valve (one-way valve) arrangement structure. The one-way valve 4 mainly includes: a connecting shell 11, an elastic component 12, a rotating shaft 13, a rotating baffle 14, and a rotating fixed seat 15. The first fuel tank 1 is connected to the second fuel tank 2 through the one-way valve 4. The first fuel tank 1 mainly supplies fuel to the engine and is connected to an oil suction pipe 3. The oil level of the first fuel tank 1 can be guaranteed when the whole machine is tilted.

[0065] The limit valve (one-way valve) has an elastic component. The elastic component 12 is a torsion spring installed on the rotating shaft 13. One end is attached to the rotating baffle 14 and the other end is attached to the rotating fixed seat 15. It is used to pre-tighten the rotating baffle 14 so that the rotating baffle 14 can fit and contact with the rotating fixed seat 15 to achieve sealing of the contact surface.

[0066] The rotating baffle 14 has a rotating shaft, one side of which is flat and can fit in contact with the rotating fixed seat 15 to act as a seal. A small gap 17 is designed at the bottom so that a smaller gap remains after fitting with the rotating fixed seat 15, so that the oil tank liquid level can be kept consistent when the vehicle is parked for a long time.

[0067] In addition, the utility model also provides a tractor, comprising an oil supply device as described in any one of the above.

[0068] The beneficial effect of adopting the technical solution of the utility model is as follows: by designing a one-way valve with a connecting shell, an elastic component, a rotating baffle, and a rotating fixed seat, the one-way valve can be arranged on the connecting pipe at the bottom of the two fuel tanks, and the fuel flows in the fuel tank without the oil suction pipe. The fuel can be supplied to the fuel tank with the oil suction pipe according to the oil height. In this way, when the whole machine is operating on a slope, due to the side tilt of the whole machine, when the fuel tank with the oil suction pipe installed is in a high position, the one-way valve basically limits the fuel flow to the low-position fuel tank, thereby ensuring that the oil suction pipe can maintain a certain fuel volume and can absorb fuel, thereby improving the utilization rate of the fuel and effectively increasing the working time.

[0069] A novel fuel supply arrangement structure (fuel supply device) and agricultural machinery (tractor) adopt a novel one-way valve (one-way valve) arrangement structure. The one-way valve 4 mainly includes: a connecting shell 11, an elastic component 12, a rotating shaft 13, a rotating baffle 14, and a rotating fixed seat 15. The first fuel tank 1 is connected to the second fuel tank 2 through the one-way valve 4. The first fuel tank 1 mainly supplies fuel to the engine 5 and is connected with an oil suction pipe 3. When the whole machine is tilted, the oil level of the first fuel tank 1 can be guaranteed. Regardless of whether the whole machine is horizontal, the first fuel tank 1 is higher than the second fuel tank 2, or the first fuel tank 1 is lower than the second fuel tank 2, the liquid level of the fuel in the first fuel tank 1 is achieved, ensuring that the oil suction pipe can suck up the fuel, ensuring the normal operation of the engine, and improving work efficiency.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
