Description

Technical Field

[0001] This utility model relates to the field of agricultural product turnover technology, and in particular to an agricultural product preservation and transportation turnover box. Background Technology

[0002] Traditional agricultural product storage and preservation turnover boxes are mainly used in the agricultural planting industry to carry and transfer harvested agricultural products. With the development of modern agriculture and the gradual increase in agricultural output, agricultural products need to be transferred during the sales process to maintain their freshness. Therefore, these preservation turnover boxes play a very important role.

[0003] Chinese patent document CN219602101U discloses a storage and preservation turnover box for agricultural products. Cooling ice cubes are placed in a storage box and inserted into an installation groove. Cold air can be effectively transferred to the upper support plate through through holes, and then the cold air is transferred to the top of the agricultural products through the holes in the support plate, so as to keep them at a low temperature. At the same time, a vacuum groove is opened in the inner wall of the turnover box to prevent the temperature from dissipating. The support plate suspends the agricultural products and keeps the outside dry, reducing the rate of spoilage, thereby improving the practicality of the device.

[0004] The existing technology has the following problems:

[0005] First, the aforementioned structure has a limited function and is unsuitable for agricultural products that do not require refrigeration and need to be transported at room temperature with ventilation. Although the protective cover has multiple ventilation holes, the ventilation effect is generally poor.

[0006] Second, the above structure has a limited scope of application and cannot transport agricultural products that require high humidity storage. It also requires frequent opening of the protective cover to check and operate when providing humidity to agricultural products, which is not convenient. Utility Model Content

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] like Figures 1-7 As shown, a fresh agricultural product transport turnover box includes a movable box body 1. A box door is hinged to the front side of the box body 1. Partitions 4 are fixedly installed on the upper and lower parts of the inner wall of the box body 1. The two partitions 4 divide the box body 1 from top to bottom into a normal temperature cavity 5, a high humidity cavity 6 and a cold storage cavity 7. L-shaped support rails 8 are fixedly installed on the left and right sides of the inner walls of the normal temperature cavity 5, the high humidity cavity 6 and the cold storage cavity 7. Support plates 9 are slidably connected to the inner walls of two adjacent support rails 8. A container box 10 is fixedly installed at the upper end of each support plate 9. A normal temperature ventilation component 2 is fixedly connected to the top of the left and right sides of the box body 1. A humidification component 3 is fixedly connected to the bottom of the rear side of the box body 1.

[0033] The ambient temperature ventilation component 2 includes two mounting frames 21. Ventilation slots 22 are provided through the top of the left and right sides of the housing 1. Both ventilation slots 22 are located inside the ambient temperature cavity 5. The opposite sides of the two mounting frames 21 are fixedly connected to the top of the left and right sides of the housing 1. The two mounting frames 21 are arranged around the two ventilation slots 22. Filter plates 23 are movably connected to the inner walls of the two mounting frames 21.

[0034] The humidification component 3 includes a water tank 31. The front side of the water tank 31 is fixedly connected to the bottom rear side of the housing 1. A water supply pipe is fixedly installed and connected to the upper left side of the water tank 31. A water pump 32 is fixedly installed in the middle rear side of the housing 1. The input end of the water pump 32 extends into the interior of the water tank 31. The output end of the water pump 32 is fixedly connected to a water supply pipe 33, which extends into the interior of the high humidity chamber 6.

[0035] The ambient temperature ventilation component 2 provides controllable air circulation to the ambient temperature chamber 5, expelling gases such as carbon dioxide and ethylene produced by the respiration of agricultural products, while filtering external dust and extending the shelf life of agricultural products. The humidification component 3 provides precise humidity control to the high humidity chamber 6, maintaining a relative humidity of 90%-95% through a spray system, suitable for preserving agricultural products with high moisture requirements such as leafy vegetables, mushrooms, and tropical fruits.

[0036] It should be noted that damping telescopic rods are fixedly installed at the four lower corners of the enclosure 1. Each damping telescopic rod has a shock-absorbing spring movably fitted onto its outer wall, and each damping telescopic rod has a fixedly connected caster wheel with brake pads at its lower end. This is existing technology and will not be elaborated upon further. Sealing strips are installed at the contact points between the enclosure door and the enclosure 1 and the partition 4.

[0037] like Figure 7As shown, the upper ends of the two mounting frames 21 are provided with through grooves, and the inner walls of the two through grooves are slidably connected to the front and rear sides of the two filter plates 23.

[0038] It should be noted that the filter plate 23 can be pulled out from the top of the mounting frame 21 without disassembling the entire assembly, making it convenient to clean dust or replace it and maintain ventilation efficiency.

[0039] like Figure 6 As shown, a connecting pipe 34 is fixedly installed in the middle of the inner wall of the box 1, below the top partition 4. The front part of the water supply pipe 33 is fixedly connected to the rear part of the outer wall of the connecting pipe 34 and they are connected in communication. Several branch pipes 35 arranged in a linear pattern are fixedly installed at the bottom of the outer wall of the connecting pipe 34. Each branch pipe 35 has a spherical spray head 36 threadedly connected to its inner wall.

[0040] It should be noted that the spherical spray head 36 sprays water mist at multiple angles, and the linear branch pipe 35 layout ensures uniform humidity distribution within the high humidity chamber 6, avoiding localized areas that are too dry or too wet.

[0041] like Figure 6 As shown, several spray nozzles 36 are located above the central container 10.

[0042] like Figure 4 As shown, a humidity sensor 37 is fixedly installed on the right side of the inner wall of the box 1, above the middle container 10.

[0043] It should be noted that the humidity sensor 37 provides data support for subsequent linkage control, such as linkage with the water pump 32, to ensure that the humidity is maintained within the set range and to achieve automated preservation management. The control system and power supply system are fixedly connected to the rear right side of the cabinet 1. The humidity sensor 37 transmits the humidity signal inside the high humidity chamber 6 to the control system, which then starts and stops the water pump 32 to maintain the humidity inside the high humidity chamber 6 at 90%-95%.

[0044] like Figure 5 As shown, baffles 11 are fixedly installed in the middle of the four sides of the outer wall of the three containers 10, and a placement rack 12 is attached to the upper end of each of the four baffles 11.

[0045] It should be noted that the baffle 11 restricts the lateral movement of the placement rack 12, thereby improving stability during transportation and reducing collision damage to agricultural products.

[0046] like Figure 5 As shown, a fixed frame 13 is fixedly installed on the bottom of the inner wall of the box 1. Slide grooves 14 are provided on the left and right sides of the bottom of the inner wall of the fixed frame 13. A refrigerator box 15 for placing ice packs is slidably connected to the inner wall of the two slide grooves 14. The upper end of the refrigerator box 15 overlaps with the lower end of the bottom support plate 9. Several evenly distributed ventilation holes 16 are provided through the lower ends of the bottom support plate 9 and the container box 10.

[0047] It should be noted that using ice packs instead of power-consuming refrigeration equipment reduces transportation costs and is suitable for short-distance cold chain needs. Furthermore, the 16 vents design allows cold air to rise evenly within the refrigeration chamber 7, avoiding localized temperature differences and improving refrigeration efficiency.

[0048] like Figure 1 and Figure 4 As shown, adjustable louvered ventilation structures 17 are provided on the left and right sides of the box 1, corresponding to the high humidity chamber 6 and the refrigeration chamber 7.

[0049] It should be noted that the ventilation volume can be adjusted according to the actual conditions of the crops stored in the high humidity chamber 6 and the cold storage chamber 7 by adjusting the opening degree of the louvers. In practice, some crops require both high humidity or cold storage and respiration. Therefore, the louvered ventilation structure 17 is designed to change the ventilation volume while maintaining the humidity and temperature of the high humidity chamber 6 and the cold storage chamber 7. In actual use, to ensure humidity and temperature, the louver opening degree is adjusted to 10°-30°, allowing a very small amount of airflow (wind speed ≤0.1m / s) to enter, just enough to meet the gas exchange requirements. The louvers are periodically (e.g., every 4 hours) briefly opened (5-10 minutes) for rapid ventilation, then closed to avoid changes in humidity and temperature.

[0050] The working principle of this invention is as follows: During use, different crops are placed into the containers 10 within the ambient temperature chamber 5, high humidity chamber 6, and refrigeration chamber 7, respectively, according to their specific needs. Each container 10 has an internal shelf for holding the crops. Furthermore, an appropriate amount of ice packs are placed in the refrigeration container 15 within the fixed frame 13, providing refrigeration for the crops in the top container 10. Using ice packs replaces power-consuming refrigeration equipment, reducing transportation costs and making it suitable for short-distance cold chain needs. This aligns with the operation mode of a turnover box. The ambient temperature chamber 5 is used to transport crops stored at ambient temperature. The ventilation slot 22 can expel gases such as carbon dioxide and ethylene produced by the respiration of agricultural products, and the filter plate 23 filters external dust, extending the shelf life of agricultural products. The high-humidity chamber 6 is used to transport agricultural products that require moisture preservation. A control system and power supply system are fixedly connected to the rear right side of the housing 1. A humidity sensor 37 transmits the humidity signal inside the high-humidity chamber 6 to the control system. The control system starts and stops the water pump 32, which pumps water from the water tank 31 into the water supply pipe 33 and connecting pipe 34. Finally, water is sprayed out by several spherical spray nozzles 36, maintaining the humidity inside the high-humidity chamber 6 at 90%-95%. The refrigeration chamber 7 is used to transport agricultural products that require refrigeration. Furthermore, the vent 16 design allows the cold air in the refrigeration chamber 7 to rise evenly, avoiding localized temperature differences and improving the refrigeration effect.

[0051] Secondly, based on practical considerations, some crops require both high humidity or refrigeration while also needing to breathe. Therefore, the design of the louvered ventilation structure 17 allows for adjustments to the ventilation volume while maintaining the humidity and temperature of the high-humidity chamber 6 and the refrigeration chamber 7. In practical use, to ensure humidity and temperature, the louver opening is adjusted to 10°-30°, allowing a very small amount of airflow (wind speed ≤0.1m / s) to just meet the gas exchange requirements. The louvers are periodically (e.g., every 4 hours) briefly opened (5-10 minutes) for rapid ventilation, then closed to prevent changes in humidity and temperature.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
