Description

Technical Field

[0001] This utility model relates to the field of fuel tank technology, specifically to a labyrinth-type anti-sway buffer assembly for agricultural machinery fuel tanks. Background Technology

[0002] The fuel tank is an indispensable component of agricultural machinery, responsible for storing and supplying fuel to support the normal operation of the machinery. Its design rationality and stability directly affect the machine's working efficiency and safety. In agricultural production, agricultural machinery often operates in complex field environments, where uneven terrain and bumps cause fuel to slosh within the fuel tank. This sloshing not only leads to unstable fuel supply but can also cause malfunctions in the fuel pump and even serious problems such as engine stalling. Therefore, to suppress fuel sloshing, anti-sloshing baffles are installed inside the fuel tank to reduce fluctuations in fuel levels during operation.

[0003] Patent CN218536351U discloses a sway-resistant and noise-reducing fuel tank with a built-in anti-sloshing plate combined with sponge. The technical solution includes a fuel tank and an anti-sloshing plate. An inner shell is installed on the inner surface of the fuel tank via spacers. Positioning posts are installed at the four corners of the top of the inner shell. A compression post is sleeved at the bottom center of each positioning post. A spring is installed inside the positioning post at the top of the compression post via a spring groove. An anti-sloshing plate is installed at the bottom of the compression post. An oil-proof sleeve is installed on the outer surface of the anti-sloshing plate. The oil-proof sleeve is filled with a sponge filling layer, and an oil-permeable pipe is sleeved inside the oil-proof sleeve. This sway-resistant and noise-reducing fuel tank with a built-in anti-sloshing plate combined with sponge solves the problem that existing fuel tank structures are relatively simple and have limited buffering effect against the impact of oil. During use, the oil impacts the inner wall of the fuel tank, easily causing swaying and affecting the stability of the fuel tank. This design reduces the impact force of the oil, thereby improving the stability of the fuel tank during use.

[0004] However, although the aforementioned existing technologies can suppress fuel sloshing to some extent, the lack of effective anti-sloshing measures on the front and rear sides of the inner shell, due to the presence of buffer seats on both sides adjacent to the partition, means that the fuel tank may still experience significant sloshing when subjected to forward and backward inertial forces. This negatively impacts the stability of the fuel tank. To address this deficiency, we propose a labyrinth-type anti-sloshing buffer assembly for agricultural machinery fuel tanks, aiming to further enhance the stability of the fuel tank through design and ensure a stable fuel supply under various operating conditions. Utility Model Content

[0005] The purpose of this invention is to provide a labyrinth-type anti-sway buffer assembly for agricultural machinery fuel tanks to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The agricultural machinery fuel tank labyrinth-type anti-sway buffer assembly includes a fuel tank, which stores and supplies fuel. As the main structure of the assembly, it is combined with... Figure 2 , Figure 5 and Figure 6 As shown, the fuel tank's inner wall has irregularly shaped baffles on all four sides. These baffles work in conjunction with the inner wall to form a labyrinthine anti-sway channel, dividing the interior of the fuel tank into multiple interconnected areas to reduce the amplitude of swaying. The multiple irregularly shaped baffles and the inner wall of the fuel tank form a labyrinthine anti-sway channel, which slows down fuel swaying and disperses impact energy through a tortuous path. The fuel tank also has a vertically movable buffer float that floats on the fuel surface, absorbing fuel impact through its own buoyancy to further suppress swaying. The buffer float has clearance openings for the multiple irregularly shaped baffles to pass through, preventing them from obstructing the vertical movement of the buffer float while maintaining the integrity of the labyrinthine structure.

[0008] Preferred, combined Figure 1 , Figure 2 and Figure 6 As shown, the top of the fuel tank is equipped with a fuel injection pipe, and the end of the fuel injection pipe is threaded with a sealing cap. The fuel injection pipe is used to inject fuel into the fuel tank and prevent fuel leakage through the sealing cap. The top of the fuel tank is also equipped with a pressure balancing device. The bottom left side of the fuel tank is equipped with a fuel outlet pipe, which is used to stably deliver fuel to the engine to ensure continuous fuel supply.

[0009] The top of the inner wall of the fuel tank is provided with an extension pipe that communicates with the fuel injection pipe. The bottom end of the extension pipe is located in the lower middle part of the fuel tank. The extension pipe is used to guide the injected fuel to the lower middle part of the fuel tank to avoid air bubbles caused by fuel surface fluctuations. The top of the buffer float is provided with a clearance hole for the extension pipe to pass through. The clearance hole ensures that the extension pipe does not affect the floating of the buffer float when it passes through it.

[0010] Preferred, such as Figure 1 As shown, the outer wall of the fuel tank has two mounting slots arranged symmetrically on the left and right. The mounting slots are used to cooperate with the agricultural machinery bracket to fix the fuel tank and enhance the overall stability.

[0011] Preferred, such as Figure 3 As shown, the tops of the multiple irregularly shaped baffles are all fixedly connected to the top of the inner wall of the fuel tank. The bottom of the irregularly shaped baffles is 1-5mm away from the bottom of the inner wall of the fuel tank. This gap is used to ensure that the fuel flows freely at the bottom, avoids fuel stagnation, and does not affect the anti-sway effect of the labyrinth-type anti-sway channel.

[0012] Preferred, combined Figure 5 and Figure 6As shown, four first positioning vertical rods are arranged in a matrix between the upper and lower sides of the inner wall of the fuel tank. The first positioning vertical rods are used to guide the vertical movement of the buffer float and prevent it from deviating or tilting. Four first wear-resistant sleeves are provided through the top of the buffer float. The four first wear-resistant sleeves are slidably connected to the outside of the four first positioning vertical rods respectively. The first wear-resistant sleeves slide with the first positioning vertical rods to reduce friction loss and ensure smooth movement of the buffer float.

[0013] A second positioning vertical rod is provided between the upper and lower sides of the inner wall of the fuel tank and at the middle position. The second positioning vertical rod is used to strengthen the positioning of the middle part of the buffer float and improve the overall stability. A second wear-resistant sleeve is provided through the middle of the top of the buffer float. The second wear-resistant sleeve is slidably connected to the outside of the second positioning vertical rod. The second wear-resistant sleeve cooperates with the second positioning vertical rod to further distribute the force and extend the service life of the component.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The labyrinth-type anti-sway buffer assembly for agricultural machinery fuel tanks, through the cooperation of buffer floats and irregularly shaped partitions, forms a tortuous fuel flow path in the labyrinth-type anti-sway channel, effectively dispersing the impact energy of fuel in the front-back, left-right, and up-down directions, significantly suppressing multi-dimensional swaying, and solving the problem of insufficient anti-swaying on the front and back sides of traditional fuel tanks.

[0016] 2. The labyrinth-type anti-sway buffer assembly of the agricultural machinery fuel tank has a buffer float that floats on the oil surface and can move up and down with the oil surface fluctuations to directly absorb the energy of fuel swaying. At the same time, it works in conjunction with the labyrinth-type anti-sway channel to form a dual sway suppression effect of physical isolation and floating buffer, further improving the stability of fuel supply.

[0017] 3. The labyrinth-type anti-sway buffer assembly of the agricultural machinery fuel tank, through the cooperation of the first positioning vertical rod, the second positioning vertical rod and the wear-resistant sleeve block, ensures that the buffer float moves stably in the vertical direction and prevents deviation or tilting.

Detailed Implementation

[0025] 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 protection scope of the present utility model.

[0026] Please see Figures 1-6 This utility model provides a technical solution:

[0027] The agricultural machinery fuel tank labyrinth-type anti-sway buffer assembly includes a fuel tank 100, which stores and supplies fuel. As the main structure of the assembly, it is combined with... Figure 2 , Figure 5 and Figure 6 As shown, the fuel tank 100 has irregularly shaped baffles 200 on all four sides of its inner wall. The irregularly shaped baffles 200 are used to cooperate with the inner wall of the fuel tank 100 to form a labyrinth-type anti-sway channel 700, dividing the interior of the fuel tank 100 into multiple connected areas to reduce the amplitude of swaying. The multiple irregularly shaped baffles 200 and the inner wall of the fuel tank 100 form a labyrinth-type anti-sway channel 700. The labyrinth-type anti-sway channel 700 slows down fuel swaying and disperses impact energy through a tortuous path. The fuel tank 100 is equipped with a buffer float 300 that can move up and down. The buffer float 300 floats on the oil surface and absorbs fuel impact through its own floating, further suppressing swaying. The buffer float 300 has a clearance opening 310 for the multiple irregularly shaped baffles 200 to pass through. The clearance opening 310 is used to prevent the irregularly shaped baffles 200 from obstructing the up and down movement of the buffer float 300, while maintaining the integrity of the labyrinth structure.

[0028] In this embodiment, combined with Figure 1 , Figure 2 and Figure 6As shown, the top of the fuel tank 100 is provided with a fuel injection pipe 110, and the end of the fuel injection pipe 110 is threaded with a sealing cap. The fuel injection pipe 110 is used to inject fuel into the fuel tank 100 and prevent fuel leakage through the sealing cap. The top of the fuel tank 100 is also provided with a pressure balancing device. The bottom left side of the fuel tank 100 is provided with a fuel outlet pipe 120. The fuel outlet pipe 120 delivers fuel to the engine stably through a conduit to ensure continuous fuel supply.

[0029] The top of the inner wall of the fuel tank 100 is provided with an extension pipe 600 that communicates with the fuel injection pipe 110. The bottom end of the extension pipe 600 is located in the lower middle part of the fuel tank 100. The extension pipe 600 is used to guide the injected fuel to the lower middle part of the fuel tank 100 to avoid air bubbles caused by fuel surface fluctuations. The top of the buffer float 300 is provided with a clearance hole 340 for the extension pipe 600 to pass through. The clearance hole 340 ensures that the extension pipe 600 does not affect the floating of the buffer float 300 when it passes through it.

[0030] Specifically, such as Figure 1 As shown, the outer wall of the fuel tank 100 has two mounting slots 130 arranged symmetrically on the left and right. The mounting slots 130 are used to fix the fuel tank 100 in conjunction with the agricultural machinery bracket to enhance the overall stability.

[0031] Furthermore, such as Figure 3 As shown, the tops of multiple irregularly shaped baffles 200 are fixedly connected to the top of the inner wall of the fuel tank 100, and the bottom of the irregularly shaped baffles 200 is 1-5mm away from the bottom of the inner wall of the fuel tank 100. This gap is used to ensure that the fuel flows freely at the bottom and avoids fuel stagnation, while not affecting the anti-sway effect of the labyrinth-type anti-sway channel 700.

[0032] Furthermore, in combination Figure 5 and Figure 6 As shown, four first positioning vertical rods 400 arranged in a matrix are provided between the upper and lower sides of the inner wall of the fuel tank 100. The first positioning vertical rods 400 are used to guide the vertical movement of the buffer float 300 and prevent it from deviating or tilting. Four first wear-resistant sleeves 320 are provided through the top of the buffer float 300. The four first wear-resistant sleeves 320 are slidably connected to the outside of the four first positioning vertical rods 400 respectively. The first wear-resistant sleeves 320 and the first positioning vertical rods 400 slide in cooperation to reduce friction loss and ensure smooth movement of the buffer float 300.

[0033] A second positioning vertical rod 500 is provided between the upper and lower sides of the inner wall of the fuel tank 100 and at the middle position. The second positioning vertical rod 500 is used to strengthen the positioning of the middle part of the buffer float 300 and improve the overall stability. A second wear-resistant sleeve 330 is provided through the middle of the top of the buffer float 300. The second wear-resistant sleeve 330 is slidably connected to the outside of the second positioning vertical rod 500. The second wear-resistant sleeve 330 cooperates with the second positioning vertical rod 500 to further distribute the force and extend the service life of the component.

[0034] In this embodiment, the labyrinth-type anti-sway buffer assembly for agricultural machinery fuel tanks is used by first fixing the fuel tank 100 to the agricultural machinery through the mounting grooves 130 symmetrically arranged on the outer wall of the fuel tank 100 and the agricultural machinery bracket. Fuel is then injected into the fuel tank 100 through the fuel injection pipe 110. After the fuel is injected, the buffer float 300 floats on the fuel surface. When the fuel sloshes due to bumps during operation, the labyrinth-type anti-sway channel 700 formed by the irregularly shaped baffle 200 and the inner wall of the fuel tank 100 slows down the fuel flow and disperses the impact energy through a tortuous path. At the same time, the buffer float 300 moves up and down with the fuel surface and avoids the impact through the avoidance opening 310. The obstruction of the irregularly shaped baffle 200 absorbs the fuel impact; during this process, the first positioning vertical rod 400 and the second positioning vertical rod 500 guide the buffer float 300 to move vertically through the first wear-resistant sleeve block 320 and the second wear-resistant sleeve block 330 respectively, preventing deviation or tilting; fuel is stably output through the fuel outlet pipe 120, and the 1-5mm gap between the bottom of the irregularly shaped baffle 200 and the inner wall of the fuel tank 100 ensures that the fuel flows freely at the bottom and avoids stagnation; finally, through the multiple synergistic effects of the labyrinth-type anti-sway channel 700, the buffer float 300 and the positioning vertical rod, the fuel tank 100 achieves efficient sway suppression and stable fuel supply in complex operating environments.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
