Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery parts technology, specifically relating to a rotationally molded agricultural machinery fuel tank cover. Background Technology

[0002] Agricultural machinery typically requires a fuel engine for operation in the field. Currently, most agricultural machinery fuel tanks are made of sheet metal, manufactured using stamping, bending, welding, and painting processes. The paint is prone to peeling in humid environments and under direct sunlight, and the paint fragments are highly toxic and environmentally unfriendly. Furthermore, due to the complex structure of agricultural machinery, it is difficult to provide a flat space for the fuel tank; usually, the tank needs to be designed with an irregular shape. Processing irregular shapes from sheet metal is difficult, and installation is also challenging. After installation, an additional decorative panel is required for protection, affecting the aesthetics.

[0003] Rotational molding parts can be molded in one piece, making it easier to process irregularly shaped parts, with lower costs, and making them more suitable for mass production. However, rotational molding parts have lower strength, and the fuel tank opening of plastic parts is easily affected by thermal expansion and contraction, limiting their application scenarios. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of how to integrate the fuel tank and the trim panel, using rotational molding to form a single piece, thereby improving the strength of the fuel tank cover, and to provide a rotational molded fuel tank cover for agricultural machinery.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A rotationally molded fuel tank cover for agricultural machinery, characterized in that it includes a fuel tank cover, a fuel tank cap, and a fuel inlet.

[0007] Furthermore, the fuel tank cover is hollow, with a fuel tank cover at the top and a lower oil inlet at the bottom. The front side wall of the fuel tank cover has an outer reinforcing rib and an inner reinforcing rib. The inner reinforcing rib has an irregularly shaped reinforcing rib that matches the shape of the parts at the fuel tank of the agricultural machinery.

[0008] Furthermore, a fuel tank reinforcement hole is provided between the front and rear side walls of the fuel tank cover, and fuel tank slots are provided vertically through the left and right ends of the fuel tank cover, with fuel tank fixing holes provided horizontally through the fuel tank slots.

[0009] Furthermore, the fuel tank cover consists of a fuel tank base and a fuel tank top cover, with the top cover mounted on the fuel tank base.

[0010] Furthermore, a cutting groove is provided in the middle of the fuel tank base.

[0011] Furthermore, pre-embedded nuts are provided on both sides of the cutting groove.

[0012] Furthermore, a stepped sleeve is provided on the top cover of the fuel tank at the position corresponding to the pre-embedded nut.

[0013] Furthermore, the stepped sleeve extends through the top cover of the fuel tank, and the bottom of the stepped sleeve is embedded in the fuel tank base.

[0014] Furthermore, lifting bolts are installed inside the step sleeve, and the lifting bolts pass through the step sleeve and are fixed with the pre-embedded nuts.

[0015] Furthermore, the height of the upper surface of the pre-embedded nut is lower than the height of the upper surface of the oil tank base.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model replaces the traditional design of two sheet metal parts, the fuel tank and the protective cover, with a fuel tank cover made of rotational molding material. The rotational molding design achieves integrated manufacturing, and the shape of the inner reinforcing ribs can be designed according to the shape of the parts between the fuel tank cover and the agricultural machinery, which increases the fit between the fuel tank cover and the agricultural machinery and reduces the volume of the fuel tank cover. The rectangular shape of the fuel tank cover is not only beautiful and easy to install, but also increases the fuel tank capacity and has wide applicability.

[0018] 2. This utility model provides a through-hole reinforcement hole in the rotomolded fuel tank cover. The reinforcement hole can provide support for the hollow fuel tank cover, reduce the expansion of the fuel tank cover, reduce the deformation of the front and rear side walls of the fuel tank cover, and improve the impact resistance of the fuel tank cover. By setting a recessed pre-embedded nut on the fuel tank base, the deformation of the rotomolded material after demolding and cooling is reduced, the flatness between the fuel tank base and the fuel tank cover is improved, and gasoline leakage at the fuel tank cover is reduced.

[0028] 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.

[0029] Example 1:

[0030] Please see Figures 1-5 As shown, a rotationally molded agricultural machinery fuel tank cover includes a fuel tank cover 1, a fuel tank cap 2, and a fuel inlet 3.

[0031] The fuel tank cover 1 is hollow and used to load gasoline. The top of the fuel tank cover 1 is equipped with a fuel tank cap 2 and the bottom is equipped with a fuel inlet 3. The front side wall of the fuel tank cover 1 is equipped with an outer reinforcing rib 4 and an inner reinforcing rib 5. The inner reinforcing rib 5 is equipped with an irregularly shaped reinforcing rib 501. The irregularly shaped reinforcing rib 501 is adapted to the shape of the parts of the agricultural machinery fuel tank, improving the fit between the fuel tank cover 1 and the agricultural machinery. A fuel tank reinforcement hole 6 is provided through the front and rear side walls of the fuel tank cover 1. The fuel tank reinforcement hole 6 can provide support for the hollow fuel tank cover 1, reduce the expansion of the fuel tank cover 1, and reduce the deformation of the front and rear side walls of the fuel tank cover 1.

[0032] The fuel tank cover 1 has vertically penetrating fuel tank slots 7 at both ends, which are used to snap the fuel tank cover 1 onto the agricultural machinery. The fuel tank slots 7 have horizontally penetrating fuel tank fixing holes 8. The fuel tank cover 1 is fixed to the sheet metal part on the fuel tank slots 7 by passing bolts through the fuel tank fixing holes 8.

[0033] Please see Figure 6-7As shown, the fuel tank cover 2 consists of a fuel tank base 201 and a fuel tank top cover 202. The fuel tank top cover 202 is set on the fuel tank base 201. A cutting groove 205 is provided in the middle of the fuel tank base 201. The cutting groove 205 can strengthen the sealing surface and reduce the deformation of the fuel tank base 201. Pre-embedded nuts 203 are provided on both sides of the cutting groove 205. A stepped sleeve 206 is provided on the fuel tank top cover 202 at the position corresponding to the pre-embedded nuts 203. The stepped sleeve 206 penetrates the fuel tank top cover 202. The bottom of the stepped sleeve 206 is embedded in the fuel tank base 201. A lifting bolt 204 is provided inside the stepped sleeve 206. The lifting bolt 204 passes through the stepped sleeve 206 and is fixed to the pre-embedded nuts 203.

[0034] Please see Figure 8 As shown, the height of the upper surface of the pre-embedded nut 203 is lower than the height of the upper surface of the oil tank base 201.

[0035] Since the plane between the fuel tank cover 202 and the fuel tank base 201 is sealed with a sealing gasket in the later stage, a high degree of flatness is required. However, the rotational molding plastic material will shrink. By sinking the pre-embedded nut 203, that is, the height of the upper surface of the pre-embedded nut 203 is lower than the height of the upper surface of the fuel tank base 201, the degree of protrusion of the surface of the pre-embedded nut 203 after the fuel tank cover 1 is demolded and cooled is reduced, thereby improving the sealing effect of the fuel tank cover 2.
