Description

Technical Field

[0001] This utility model relates to the field of tractor oil filter protection, specifically to an oil filter protection device and a tractor. Background Technology

[0002] With the rapid development of agricultural mechanization, tractors, as important agricultural operating equipment, play a vital role in field operations. When tractors work in complex and changing field environments, the chassis area often faces risks such as scrapes and collisions, especially critical components such as the fuel filter assembly (oil filter assembly) are easily damaged. The fuel filter assembly includes an oil-water separator, a coarse diesel filter, a fine diesel filter, inlet fuel lines, and return fuel lines. As a key component of the tractor's hydraulic and lubrication systems, the proper functioning of the fuel filter assembly directly affects the overall reliability and service life of the machine.

[0003] Currently, most oil filter protection devices on the market adopt an integrated metal bent plate structure, which is fixed to the bottom of the oil filter assembly with bolts. Although this structure is simple to manufacture and has a low cost, it has obvious shortcomings in actual use. For example, the metal plate is prone to deformation after frequent impacts, which leads to a decrease in protective performance, reducing the protective effect and service life.

[0048] The second fixing frame 103 is U-shaped, and its two ends are respectively fixed to the left side 1051 and the right side 1053 of the third fixing frame 105.

[0049] A fuel filter bracket 104 is provided, with one end fixedly connected to the lower part of the first fixing frame 102 and the other end fixedly connected to the front side 1052 of the third fixing frame 105. The space enclosed by the third fixing frame 105, the first fixing frame 102, the second fixing frame 103, and the fuel filter bracket 104 is an installation space for installing the fuel filter assembly. The fuel filter bracket 104 is also welded to the bottom of the second fixing frame 103.

[0050] A front connecting plate 101 is located on the rear side of the lower part of the first fixing frame 102 and is used to fix it to the machine body 4. The front connecting plate 101 has multiple threaded holes for fixing it to the machine body 4 with bolts, which facilitates disassembly and assembly.

[0051] Specifically, the installation space is used to install the oil-water separator 201 and the diesel coarse filter 203 of the fuel filter assembly, and the diesel filter bracket 104 is used to support the oil-water separator 201 and the diesel coarse filter 203.

[0052] The left side 1051 of the third fixing frame 105 is provided with an oil-water separation bracket 108 for fixing the oil-water separator 201.

[0053] A horizontal mounting plate 111 is provided at one end of the diesel filter bracket 104 that is connected to the third fixing frame 105. The horizontal mounting plate 111 has at least two bolt holes reserved for installing the diesel coarse filter 203.

[0054] The oil filter protection bracket 1 also includes a reinforcing connecting plate 106 and an electronic pump bracket 107;

The oil filter protection bracket 1 is used as a module for the installation of the fuel filter assembly. Its overall structure is detachable, facilitating quick removal and reinstallation during maintenance and avoiding damage to the pipeline caused by disassembling individual components. The modular design allows for the centralized arrangement of multiple components of the fuel filter assembly, improving the overall aesthetics, reducing space occupation, and optimizing the assembly process.

[0060] The oil filter protection bracket 1 is fixed at three points through the front connecting fixing plate 101, the third fixing bracket 105 and the electronic pump bracket 107, which respectively restrict the degrees of freedom in the left, right, front, back and up directions.

[0061] The oil filter protection bracket 1 is made of square tube welded together, and the overall structure is modularly designed to integrate multiple components in the fuel filter assembly, including oil-water separator 201, diesel coarse filter 203, diesel fine filter 204, oil inlet pipe 202 and oil return pipe 205.

[0062] In this application, the oil filter protection bracket 1 surrounds the outside of the fuel filter assembly, which can provide external protection for the fuel filter. Compared with the one-piece metal bending plate structure in the prior art, it can expand the protection range of the fuel filter assembly and improve the protection effect.

[0063] Example 2

[0064] A tractor includes a body 4 and a fuel filter assembly, and also includes the aforementioned oil filter protection device, wherein the fuel filter assembly is mounted on the body 4 via the oil filter protection device.

[0065] The beneficial effects of the technical solution of this utility model are:

[0066] Existing technology: The oil filter protection device of existing tractor models is an integrated bent plate, which is fixed to the tractor floor by two bolts, which has the following problems;

[0067] 1. Simple structure, weak protection performance: The protection structure of the diesel coarse filter 203 is not considered, and the traditional bracket only protects the end of the oil-water separator 201, resulting in poor protection effect.

[0068] 2. Poor stability: Because it is only fixed by two bolts, and the tractor floor will vibrate with the whole machine, it is prone to loosening and falling off under harsh working conditions.

[0069] 3. Complex installation and maintenance: During maintenance, the existing oil-water separator 201 and diesel coarse filter 203 need to be removed and installed separately after maintenance. During maintenance, the intermediate pipeline is prone to breakage. It lacks a modular design concept and the overall layout is relatively messy.

[0070] Advantages of the technical solution in this application:

[0071] 1. By using a three-point fixed connection method, the six degrees of freedom (left, right, front, back, up, and down) are effectively restricted, greatly improving the overall stability.

[0072] 2. The overall frame is made of square tubes welded together, which ensures the overall structural strength, provides a large protective area, and greatly reduces the risk of damage due to excessive stress.

[0073] 3. The overall modular design concept allows for complete disassembly, preserving space for maintenance and ensuring a compact and aesthetically pleasing layout.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
