Description

Technical Field

[0001] This utility model relates to the technical field of fertilizer storage tanks, and in particular to a stackable fertilizer storage tank structure that is easy to transport. Background Technology

[0002] Currently, agricultural fertilizers are mostly packaged and stored in plastic bags or simple buckets. During long-distance transportation and on-site use, these containers often present problems such as inconvenience in handling, easy tipping, and unstable storage. Especially in scenarios where fertilizers are piled up in large quantities or frequently turned over, the structural design of traditional fertilizer containers is difficult to meet the needs of convenient stacking and efficient handling, resulting in low usage efficiency, large space occupation, and high transportation and storage costs.

[0003] Furthermore, traditional buckets are mostly standard cylindrical or top-heavy, lacking structural design for stacking stability. They are prone to slipping, tilting, or even rolling during stacking, posing significant safety hazards. While some products incorporate simple limiting structures on the lid or bottom, they still struggle to provide effective support in harsh environments or high-frequency usage scenarios, resulting in insufficient stacking stability.

[0004] Meanwhile, most existing fertilizer containers are handled manually by carrying them or using ropes, which not only increases the burden on manpower but also easily causes damage or tipping. Although some improved products have added handles or pulleys, they lack systematic structural integration, have limited versatility, and their ease of handling still needs improvement.

[0005] In view of this, the inventors specifically designed a stackable fertilizer storage tank structure that is easy to transport, and this invention is thus derived. Utility Model Content

[0031] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0032] This invention provides a stackable fertilizer storage tank structure that is easy to handle. It is primarily used for the packaging, transportation, and storage of agricultural fertilizers, and is also suitable for loading and handling solid or semi-solid materials such as industrial powders, granules, feed, and pesticides. Compared to ordinary storage tanks in the prior art, this invention not only considers stacking stability and space utilization, but also balances handling efficiency and sealing protection capabilities, offering advantages such as simple structure and ease of promotion.

[0033] like Figure 1 and Figure 2 As shown, the storage bin structure includes main components such as the bin body 1, stacking ring 2, base structure 3, handling handle 4, and bin lid 5, wherein:

[0034] The barrel body 1 has a truncated cone shape, wider at the bottom and narrower at the top. It is preferably made of corrosion-resistant, UV-resistant, and low-temperature-resistant materials such as high-strength polyethylene (HDPE) or polypropylene (PP) through one-time injection molding or blow molding, so that the barrel body 1 meets the strength requirements while having good weather resistance. The conical structure design not only facilitates the stacking of empty barrels, but also forms a stable center of gravity support when stacked, which is more conducive to improving the overall stability and safety of the stack.

[0035] The upper outer circumferential part of the barrel body 1 is provided with a stacking ring edge 2, which is shaped as a ring-shaped boss or reinforcing edge. It can be integrally formed or attached by hot welding process in the post-processing stage. The top surface or inner side of the stacking ring edge 2 may be provided with a groove 31, a step or a positioning surface for nesting or fitting with the bottom structure of the upper barrel body 1, thereby preventing slippage and effectively bearing the weight of the upper part, and enhancing the structure's resistance to displacement.

[0036] like Figure 3 As shown, the base structure 3 located at the bottom of the barrel 1 mates with the stacking ring edge 2. The base has 3 to 6 limiting grooves 31 on its outer perimeter, the shape and position of which match the stacking ring edge 2. The depth and width of each limiting groove 31 are precisely designed according to the dimensions of the stacking ring edge 2. When multiple barrels 1 are stacked, the stacking ring edge 2 of the lower barrel 1 can partially embed into the limiting groove 31 of the base of the upper barrel 1, forming a physical interlocking connection similar to a mortise and tenon joint, thereby preventing lateral slippage or displacement deviation during stacking. This structural fit facilitates rapid manual stacking, eliminates the need for additional auxiliary positioning devices, simplifies the operation process, and is suitable for large-scale storage and transportation operations.

[0037] Handles 4 are provided on both sides of the middle of the barrel body 1. These handles 4 are preferably recessed and integrally molded with the barrel body 1, resulting in an aesthetically pleasing and compact design. The inner surface of the handles 4 may be provided with anti-slip textures 41, such as stripes, granules, or wavy grooves, to increase hand grip and prevent slippage when working with gloves or wet hands. For applications involving frequent heavy-duty handling, this structure significantly reduces the user's burden and facilitates gripping operations by mechanical clamping equipment.

[0038] like Figure 3 As shown, a screw-on lid 5 is provided on the top of the barrel body 1. The lid 5 is connected to the upper opening of the barrel body 1 via a screw-on structure 6, which can be quickly rotated to open and close, making it easy to operate. A rubber sealing ring 7 is provided on the inner ring below the lid 5. The sealing ring is pressed tightly against the barrel opening, improving the overall sealing performance and effectively preventing the fertilizer from getting damp, deteriorating, or emitting odors. This is suitable for long-term storage and leak-proof requirements during transportation. A vent valve or air extraction interface can also be optionally installed on the lid 5 for vacuum sealing or preservation applications.

[0039] like Figure 2 and Figure 4As shown, to further improve handling efficiency, especially in ground-based applications, this invention can also include a detachable pulley assembly 9. The base structure 3 has multiple pulley mounting slots 8 around its perimeter for mounting pulley brackets. The pulley assembly 9 includes casters 91, wheel frames 92, and snap-fit ​​devices 93, which engage with the bottom slots 8 via plug-in or elastic snap-fit ​​methods for easy assembly and disassembly. Users can flexibly decide whether to equip the pulleys according to their needs. For example, pulleys can be used for short-distance indoor movement or stacking on flat surfaces, while they can be removed to enhance stability during transportation, loading / unloading, or outdoor use.

[0040] In summary, this utility model achieves a harmonious balance between stacking stability, ease of handling, and reliable sealing in its structural design. Its structure can be widely applied in various fields such as agricultural production, agricultural input distribution, rural e-commerce, and warehousing logistics, while also supporting mass production and modular assembly.

[0041] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
