Description

Technical Field

[0001] This utility model relates to the field of rotomolded fuel tank technology, and in particular to an easy-to-disassemble rotomolded fuel tank for loaders. Background Technology

[0002] Traditional loader fuel tanks are typically made of metal, which has poor shock resistance. Loaders operate in harsh environments with significant vibrations, making metal fuel tanks prone to damage. Rotomolded fuel tanks, on the other hand, offer excellent shock resistance and impact resistance, making them a viable alternative to metal fuel tanks and meeting the fuel tank requirements of loaders.

[0003] Loaders mostly operate outdoors, and repairs are typically performed on-site after damage. Therefore, the ease of disassembly and assembly of components during maintenance is crucial. Ordinary rotomolded fuel tanks have a regular structure, requiring corresponding brackets and clamping structures for installation on loaders. This not only makes installation cumbersome but also increases the difficulty of disassembly, necessitating improvements. Utility Model Content

[0004] The purpose of this utility model is to provide an easy-to-disassemble rotomolded fuel tank for loaders, which improves the ease of disassembly and assembly and increases capacity.

[0005] To achieve this objective, the present invention adopts the following technical solution: A rotomolded fuel tank for a loader that is easy to disassemble and assemble includes: a rotomolded fuel tank base and a pad plate. A counterweight is provided at the rear of the frame. An embedded groove is recessed at the front end of the top center of the counterweight. A first crossbeam is provided on the frame in front of the counterweight. The rotomolded fuel tank base is provided on the first crossbeam. A first extension portion extending into the embedded groove is provided at the upper part of the rear end of the rotomolded fuel tank base. A second crossbeam is provided on the frame in front of the first crossbeam. The front end of the rotomolded fuel tank base is located above the second crossbeam, and second extension portions extending to the corresponding ends of the second crossbeam are provided on both sides of the front end of the rotomolded fuel tank base. A first positioning groove is recessed on the first crossbeam. The pad plate is provided at the bottom of the rotomolded fuel tank base and located in the first positioning groove. A second positioning groove is recessed on the second crossbeam. Positioning portions extending downward into the second positioning groove are provided at the bottom of the rotomolded fuel tank base and the second extension portions.

[0006] The first crossbeam has a screw at its bottom that connects to a pad, and the pad has a threaded hole at its bottom that corresponds to the screw.

[0007] The pad is provided with a T-shaped block embedded in the bottom of the rotomolded oil tank substrate.

[0008] The pad and the T-block are made of an integrated steel structure.

[0009] The rotational molding oil tank base, positioning part, first extension part and second extension part adopt an integrated rotational molding structure.

[0010] The first extension section has an oil filler port at its top.

[0011] The rotational molding oil tank base is provided with an oil suction port at the top front end.

[0012] The beneficial effects of this utility model are as follows: An easy-to-disassemble rotomolded fuel tank for loaders is specially designed with a first extension and a second extension, which increases the capacity. The first extension is used in conjunction with the embedded groove to position the tail end of the rotomolded fuel tank base, and the second extension is used in conjunction with the vehicle frame to position the front end of the rotomolded fuel tank base, which improves the convenience and stability of installation. The positioning is further strengthened by the cooperation of the pad and the first positioning groove, and the pad can also be fixed with screws, making disassembly and assembly convenient.

[0014] The following is combined Figures 1-2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0015] like Figure 1 and Figure 2 The rotomolded fuel tank for loader shown is installed on the frame 2 of the loader and includes: a rotomolded fuel tank base 1 and a pad 6. A counterweight 3 is provided at the rear of the frame 2. An embedded groove 31 is provided inward at the front end of the top center of the counterweight 3. A first crossbeam 4 is provided on the frame 2 in front of the counterweight 3. The rotomolded fuel tank base 1 is provided on the first crossbeam 4. A first extension 14 extending into the embedded groove 31 is provided at the upper part of the rear end of the rotomolded fuel tank base 1. The rear end of the rotomolded fuel tank base 1 is positioned by the cooperation of the first extension 14 and the embedded groove 31.

[0016] A second crossbeam 5 is provided on the frame 2, located in front of the first crossbeam 4. The front end of the rotomolded fuel tank base 1 is located above the second crossbeam 5, and second extension portions 13 extending to the corresponding ends of the second crossbeam 5 are provided on both sides of the front end of the rotomolded fuel tank base 1.
