[0002] Loaders are earthwork machines widely used in construction projects such as roads, railways, buildings, hydropower, ports, and mines. They are mainly used to shovel bulk materials such as soil, sand, lime, and coal, and can also do light shoveling of ore and hard soil. By replacing different auxiliary working devices, they can also do bulldozing, lifting, and loading and unloading of other materials such as wood.

[0003] The fuel tank is an important component of the loader, providing fuel for the loader. Its layout location varies according to the different loader models, but for the convenience of layout, the fuel tank of a general loader is mostly arranged at the rear of the loader frame, such as behind the cab or under the engine and radiator. For example, the FL970 loader produced by Lovol Heavy Industries, in which the fuel tank is installed under the engine and radiator, can effectively increase the installation space of the fuel tank.

[0004] However, since the upper cover of the fuel tank is close to the engine, the engine pipeline often collides with the upper cover of the fuel tank due to bumps in the road during the operation of the loader. Lowering the height of the upper cover of the fuel tank and increasing the distance between the upper cover of the fuel tank and the engine will reduce the capacity of the fuel tank. Utility Model Content

[0005] In view of the defects or shortcomings in the prior art, the utility model provides a loader fuel tank structure, which can increase the distance between the fuel tank upper cover and the engine pipeline while ensuring the fuel tank capacity, thereby avoiding collision between the engine pipeline and the fuel tank upper cover during operation.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An embodiment of the utility model provides a loader fuel tank structure, including a fuel tank body, which is placed at the bottom of an engine and a radiator, and an upper cover plate is welded and fixed on the top of the fuel tank body, and the upper cover plate includes a first cover plate and a second cover plate, the height of the first cover plate is higher than the height of the second cover plate, and a groove is arranged on the second cover plate, and the groove is arranged opposite to the engine oil pan.

[0008] Furthermore, an inclined plate is provided between the first cover plate and the second cover plate, one end of the inclined plate is connected to the first cover plate, and the other end of the inclined plate is connected to the second cover plate.

[0009] Furthermore, a side plate is provided at one end of the second cover plate away from the first cover plate, and the side plate is arranged perpendicular to the second cover plate.

[0010] Further, the first cover plate is located below the radiator, and the second cover plate is located below the engine.

[0011] Furthermore, the first cover plate is provided with a welding flange opening and a liquid level gauge flange opening for installing the oil tank flange and the liquid level gauge.

[0012] Furthermore, the groove is arranged at one end of the second cover plate close to the side plate, and the top of the groove and the side wall opening close to one end of the side plate are arranged.

[0013] Furthermore, the groove includes a bottom plate and two baffles, and the two baffles are respectively fixed on two sides of the bottom plate.

[0014] Furthermore, one end of the bottom plate is welded and fixed to the second cover plate, and the other end is welded and fixed to the side plate. The top end of the baffle plate is welded and fixed to the second cover plate, and the bottom end of the baffle plate is welded and fixed to the bottom plate.

[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] A typical implementation of the present invention is as follows: Figure 3 As shown, a loader fuel tank structure includes a fuel tank body 1, which is placed at the bottom of an engine 2 and a radiator 3. An upper cover plate 4 is welded and fixed on the top of the fuel tank body 1, and the upper cover plate 4 is formed by bending a plate.

[0026] like Figure 1 As shown, the upper cover plate is a stepped structure, which includes a first cover plate 5, a second cover plate 6 and a side plate 7. The height of the first cover plate 5 is higher than that of the second cover plate 6. An inclined plate 8 is arranged between the first cover plate 5 and the second cover plate 6. One end of the inclined plate 8 is connected to the first cover plate 5, and the other end is connected to the second cover plate 6. The side plate 7 is arranged at one end of the second cover plate 6 away from the first cover plate 5, and is arranged perpendicular to the second cover plate 6.

[0027] Since the fuel tank body 1 is placed below the engine 2 and the radiator 3, the first cover plate 5 is located below the radiator 3, and the second cover plate 6 is located below the engine 2, the height of the second cover plate 6 is lower than the height of the first cover plate 5. While ensuring the capacity of the fuel tank, the distance between the second cover plate 6 and the engine 2 is increased, thereby avoiding collision between the upper cover plate 4 of the fuel tank and the bottom pipeline of the engine 2.

[0028] The first cover plate 5 is provided with a welding flange opening 9 and a liquid level gauge flange opening 10 for mounting the oil tank flange and the liquid level gauge.

[0029] A groove 11 is provided at one end of the second cover plate 6 close to the side plate 7. The top of the groove 11 and the side wall opening close to one end of the side plate 7 are provided. The groove 11 includes a bottom plate and two baffles. One end of the bottom plate is welded and fixed to the second cover plate 6, and the other end is welded and fixed to the side plate 7. The two baffles are located on both sides of the bottom plate. The top end of the baffle is welded and fixed to the second cover plate 6, and the bottom end of the baffle is welded and fixed to the bottom plate. The sealing of the upper cover plate 4 is ensured by welding and fixing the bottom plate and the two baffles to the second cover plate 6.

[0030] The groove 11 is arranged opposite to the engine oil pan 12, and an oil drain hose 13 is arranged at the bottom of the engine oil pan 12 to facilitate the replacement of the engine oil. Since the engine oil pan 12 is located at a relatively low position, in order to avoid the oil drain hose 13 arranged at the bottom of the engine oil pan 12 from interfering with the fuel tank body 1, a groove 11 is arranged on the upper cover plate 4, so that the oil drain hose 13 is led out from the groove 11, which can effectively increase the capacity of the fuel tank body 1 without causing interference.

[0031] like Figure 2 As shown, a support frame 14 is also provided on the second cover plate 6, and the support frame 14 is welded and fixed to the second cover plate 6. A U-shaped pipe clamp 15 is provided on the top of the support frame 14, and the engine pipeline 16 is fixed by the support frame 14 and the U-shaped pipe clamp 15 to prevent the engine pipeline 16 from colliding with the fuel tank body 1.

[0032] The utility model arranges the fuel tank upper cover plate in a stepped shape so that the height of the second cover plate located below the engine is lower than the height of the first cover plate located below the radiator. This increases the distance between the fuel tank upper cover plate and the engine without reducing the fuel tank volume, thereby avoiding collision between the engine pipeline and the fuel tank upper cover plate due to road bumps during the operation of the loader.

[0033] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
