Description

Technical Field

[0001] This utility model belongs to the technical field of agricultural storage equipment, and relates to a sweet potato storage frame, especially a sweet potato storage frame that is easy to operate with a lifting platform. Background Technology

[0002] As an important economic crop, the storage method after harvesting sweet potatoes plays a crucial role in maintaining their quality and extending their shelf life. However, the current method of directly piling sweet potatoes for storage presents many technical problems.

[0003] First, there's the problem of poor ventilation. Directly piling sweet potatoes causes them to be in close contact, resulting in poor air circulation at the bottom and inside of the pile. During storage, sweet potatoes respire, generating heat and moisture. If ventilation is poor, this heat and moisture cannot dissipate in time, causing localized high temperatures and humidity within the pile. This provides a suitable environment for the growth of pathogens, thus accelerating the rotting and spoilage of the sweet potatoes.

[0004] Secondly, humidity control is difficult. Directly stacking sweet potatoes makes it hard to effectively control humidity. When the ambient humidity is too high, the sweet potatoes are prone to becoming damp, causing the skin to soften and mold, which in turn leads to internal rot; while when the humidity is too low, the sweet potatoes will become shriveled and taste worse due to water loss. The ideal storage humidity should be maintained between 85% and 90%.

[0005] Furthermore, there is the risk of mechanical damage. During stacking and handling, sweet potatoes are prone to mechanical damage due to collisions and compression. This damage not only disrupts the skin structure, making it more susceptible to pathogen infection, but also damages the internal tissues, accelerating nutrient depletion and quality decline.

[0006] Furthermore, the risk of disease and pest transmission is high. If some sweet potatoes in directly piled sweet potatoes become infected with diseases or pests, the pathogens and pests will quickly spread throughout the pile, infecting other healthy sweet potatoes and causing large-scale rot and losses. Moreover, due to the compacted storage, early detection and treatment of diseases and pests are relatively difficult.

[0007] There is a lack of existing technologies that can comprehensively solve the above problems, ensuring good air permeability, having a stable structure, and facilitating mechanized operation of sweet potato storage equipment. Utility Model Content

[0008] Therefore, the purpose of this utility model is to provide a special equipment for improving the efficiency and quality of sweet potato storage and transportation, and to promote the modernization of the sweet potato industry.

The technical solution provided by this utility model is to provide a sweet potato storage frame that facilitates the operation of a lifting platform. The frame includes a cuboid frame with an open top surface and hollowed-out four sides and bottom surface. Support legs are provided at the bottom of the frame. A first positioning unit is provided at the bottom of a pair of opposite sides, and a second positioning unit is provided at the top that is coupled to the first positioning unit of another sweet potato storage frame.

[0016] This utility model enhances the overall structural stability of the frame by setting columns at the four corners of a cuboid frame and connecting top and bottom frame beams to the top and bottom of the columns, respectively. At the same time, a pair of opposite sides of the top frame beam are designed as a second positioning unit, and a first positioning unit is set at the bottom of the corresponding column. This not only enhances the overall structural stability of the frame, but also achieves precise positioning and stable connection of the storage boxes when stacked, significantly improving the reliability and ease of operation of multi-layer stacking.

[0017] Based on the above technical solution, the present invention can be further improved as follows:

[0018] Furthermore, a load-bearing grid is connected to the inner side of the bottom frame beam, and a bottom mesh is laid on top of the load-bearing grid.

[0058] The following description, in conjunction with the accompanying drawings and a specific embodiment, will be provided.

[0059] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0060] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

[0061] See Figures 1 to 6The sweet potato storage frame described in this embodiment is designed to facilitate the operation of a lifting platform. It includes a cuboid frame with an open top and hollowed-out four sides and bottom. Support legs are provided at the bottom of the frame. A first positioning unit is provided at the bottom of a pair of opposite sides, and a second positioning unit is provided at the top, which is coupled to the first positioning unit of another sweet potato storage frame.

[0062] Specifically, the cuboid frame includes four columns 100 located at the four corners of the cuboid frame. The top of each column 100 is connected to four top frame beams 200, and the bottom is connected to four bottom frame beams 300. A pair of opposite sides of the top frame beams 200 form a second positioning unit 210, and the bottom of each column 100 connected to the second positioning unit 210 is correspondingly provided with a first positioning unit 120. The section of the column below the bottom frame beams 300 serves as a support leg. This design not only enhances the overall structural stability of the frame but also achieves precise positioning and stable connection of the storage boxes during stacking, significantly improving the reliability and ease of operation of multi-layer stacking.

[0063] Furthermore, the bottom surface of the first positioning unit 120 is provided with a positioning groove 121, and the top surface of the second positioning unit 210 is provided with a positioning strip corresponding to the positioning groove 121. Through the cooperation of the positioning groove 121 and the positioning strip, it is ensured that the storage boxes can be quickly and accurately docked during the stacking process, effectively preventing shaking and displacement during stacking, and improving the stability and safety of stacking.

[0064] To enhance the load-bearing capacity and air permeability of the storage frame bottom, a load-bearing mesh 310 is connected to the inner side of the bottom frame beam 300, and a bottom mesh 311 is laid on top of the load-bearing mesh 310. This structural design allows the sweet potatoes to be evenly stressed during storage, avoiding damage caused by excessive local stress. At the same time, the air permeability of the bottom mesh 311 ensures good ventilation in the sweet potato storage environment, reducing the risk of rotting due to anaerobic respiration.

[0065] In addition, side railings 130 are provided on all four sides of the cuboid frame, and side netting 131 is laid on the inner side of the side railings 130. Both the bottom netting 311 and the side netting 131 are wire mesh. The mesh size of the wire mesh is smaller than the diameter of the sweet potato. The use of wire mesh not only effectively prevents the sweet potatoes from falling during storage, but also ensures air circulation within the storage frame, providing a good aeration environment for the sweet potatoes and helping to maintain their quality.

[0066] In terms of material selection, the uprights 100, top frame beam 200, and bottom frame beam 300 are all made of triangular steel. Triangular steel has high strength and stability, which can effectively improve the overall structural strength and durability of the storage frame, while reducing material costs and maintenance difficulties, ensuring the reliability and economy of the storage frame in long-term use.

[0067] To further enhance the stability of the bottom support structure of the storage frame, a support member 110 is provided between the bottom frame beam 300 and the bottom end of the column 100. The support member 110 effectively prevents frame deformation caused by gravity or external forces, ensuring the reliability and durability of the storage frame in long-term use.

[0068] The first positioning unit 120 and the second positioning unit 210 are made of triangular steel. The use of triangular steel not only improves the structural strength and durability of the positioning unit, but also ensures the accuracy and stability of the positioning of the storage frame during stacking and handling. At the same time, the properties of triangular steel further enhance the overall load-bearing capacity and deformation resistance of the storage frame.

[0069] In terms of dimensions, the rectangular frame has a length of 120±10cm, a width of 116±10cm, and a height of 50±10cm; the support legs have a height of 5-15cm. This dimensional design makes the storage frame more standardized, meeting the storage capacity requirements of sweet potatoes while ensuring good ventilation. It is also compatible with common agricultural handling machinery, improving handling efficiency and ease of operation.

[0070] In one specific embodiment, the cuboid frame is 120cm long, 116cm wide, and 50cm high, with the supporting legs being 16cm high. This dimensional design, precisely calculated, aims to achieve high efficiency and practicality in sweet potato storage. First, the 120cm length and 116cm width provide sufficient internal space to hold approximately 450kg of sweet potatoes, meeting the needs of large-scale storage. Simultaneously, the 50cm height ensures the capacity of a single storage frame without causing difficulties in handling or structural instability due to excessive height. The 16cm supporting leg height not only elevates the storage frame, allowing for bottom ventilation and effectively preventing sweet potatoes from rotting due to bottom dampness, but also allows conventional forklifts to easily insert and move the storage frames. Furthermore, these dimensions match the load-bearing capacity and operating range of conventional forklifts, allowing a conventional forklift to stack four such sweet potato storage frames at a time, significantly improving handling efficiency, reducing labor costs, and achieving mechanization and standardization of the storage and handling process.

[0071] This utility model provides a sweet potato storage frame that facilitates elevator operation. Through reasonable structural design and material selection, it effectively solves the problems of poor ventilation, difficulty in humidity control, and high risk of mechanical damage in traditional sweet potato storage methods. At the same time, it optimizes the collaborative operation with mechanized equipment, improves the efficiency and quality of sweet potato storage and transportation, and promotes the modernization of the sweet potato industry.

[0072] Of course, the sweet potato storage frame described in this embodiment does not regulate humidity itself.

The sweet potato storage frame is convenient for maintaining the uniformity of sweet potato humidity.
