Description

Technical Field

[0001] This utility model relates to the field of tractor technology, specifically to an integrated rotomolded fuel tank for tractors. Background Technology

[0002] The fuel tank is a crucial component of a tractor. Its primary function is to store fuel, while also providing functions such as heat dissipation, sedimentation of impurities, and separation of air bubbles in the fuel. The fuel tank delivers the stored fuel to the engine to ensure vehicle operation. From an overall machine perspective, the fuel tank helps balance the machine's weight distribution. A well-designed structure and appearance can reduce costs, improve fuel system performance and assembly efficiency, and enhance the overall aesthetics of the machine.

[0003] Currently, tractor fuel tanks mainly use metal fuel tanks and rotomolded fuel tanks. Although rotomolded fuel tanks were developed later than metal fuel tanks, they have significant advantages such as light weight, high freedom of design, corrosion resistance, high temperature resistance, aging resistance, and high efficiency in large-scale production. Their status has far surpassed that of metal fuel tanks. When a vehicle is going uphill and the fuel level is low, cavitation may occur. Traditional fuel tanks do not have an additional fuel storage design, which makes it difficult for the vehicle to continue going uphill after cavitation occurs, resulting in engine stalling and inability to continue going uphill. Therefore, to address the above problems, an integrated rotomolded fuel tank for tractors is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes an integrated rotomolded fuel tank for tractors.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The tractor integrated rotomolded fuel tank of this utility model includes a fuel tank body, a fuel tank cover is threadedly connected to the top of the fuel tank body, an oil inlet and an oil return port communicating with the interior are opened on the top of the fuel tank body, and an oil drain port communicating with the interior is opened on the bottom of the fuel tank body; a fuel sensor is inserted inside the fuel tank body.

[0006] Furthermore, the fuel sensor includes a fuel intake port, a level sensor, and a breather.

[0007] Furthermore, the end of the drain port is threaded with a bolt.

[0008] Furthermore, an annular oil baffle structure is provided at the bottom of the oil tank body, and the annular oil baffle structure is in the shape of a "C".

[0009] Furthermore, the fuel tank cap is secured to the fuel tank body by several screws, and the annular oil baffle structure is located below the fuel tank cap.

[0010] Furthermore, the surface of the fuel tank body is provided with several grooves and protrusions.

[0011] The advantages of this utility model are:

[0012] This invention achieves fuel storage by storing fuel within an annular fuel baffle structure. This annular baffle structure allows for fuel storage at the fuel inlet pipe, preventing fuel from being sucked into the fuel tank and affecting power when the fuel is low or when the vehicle is going uphill. This solves the problem of vehicles being unable to climb hills due to insufficient fuel. Furthermore, the fuel inlet, level sensor, and breather are integrated into the fuel sensor, resulting in more concentrated functionality and a more aesthetically pleasing appearance.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-3As shown, a tractor integrated rotomolded fuel tank includes a fuel tank body 7, a fuel tank cap 2 threadedly connected to the top of the fuel tank body 7, an inlet 3 and an outlet 4 communicating with the interior of the fuel tank body 7, and a drain port 5 communicating with the interior of the fuel tank body 7 at the bottom, with a bolt threadedly connected to the end of the drain port 5. The surface of the fuel tank body 7 has several grooves and protrusions.

[0020] Specifically, the bottom of the fuel tank body 7 is provided with an annular oil baffle structure 6, which is in the shape of a "C". The fuel tank cover 2 is fastened to the fuel tank body 7 by several screws, and the annular oil baffle structure 6 is located below the fuel tank cover 2. A fuel sensor 1 is inserted inside the fuel tank body 7. The fuel sensor 1 includes a fuel inlet, a liquid level sensor and a breather.

[0021] During operation, the fuel tank cap 2 is unscrewed, and fuel is injected into the fuel tank body 7 through the fuel inlet 3. The fuel is stored in the annular fuel baffle structure 6, thus serving the purpose of fuel storage. The annular fuel baffle structure 6 enables fuel storage at the fuel inlet pipe, preventing fuel from being sucked into the tank and affecting power when the fuel is low or when the vehicle is going uphill. This solves the problem of the vehicle being unable to climb hills due to insufficient fuel. At the same time, the design of grooves and protrusions on the surface of the fuel tank body 7 makes better use of the vehicle's space and allows for a more reasonable layout. The grooves and protrusions also make it easier for workers to move the fuel tank body 7, providing better leverage points during transport.

[0022] At the same time, the fuel intake port, level sensor and breather are integrated into fuel sensor 1, making the functions more concentrated and the appearance more aesthetically pleasing.

[0023] Working principle: Unscrew the fuel tank cap 2 and inject fuel into the fuel tank body 7 through the fuel inlet 3. The fuel is stored in the annular fuel baffle structure 6, thus achieving the purpose of fuel storage. The annular fuel baffle structure 6 can realize the function of storing fuel at the fuel inlet pipe. When the fuel is insufficient or the whole vehicle is going uphill, there will be no problem of fuel sucking in the air and affecting the power.
