[0002] With the development of cold chain logistics technology, fresh products such as prefabricated foods like shrimp paste are widely used in multiple fields such as catering and retail. Shrimp paste has characteristics such as delicate texture, rich in moisture, and easy to deform, and its quality has extremely high requirements for storage and transportation conditions. Currently, during cold chain transportation, shrimp paste is usually divided into packaging containers and stacked and placed in a freezer for frozen transportation.

[0003] However, due to the high water content and wet surface of shrimp paste itself, if the shrimp paste is stacked or squeezed, it is extremely easy to freeze and adhere during the freezing process, forming a whole block, which not only affects the appearance, but may also seriously affect subsequent separation operations and cause damage to the product.

[0004] To avoid the above problems, some enterprises try to pre-level the shrimp paste during the production process. However, during the placement in the freezer, if the operator's actions are uneven or the placement angle is slightly deviated, it may cause some containers to be in an inclined state. The inclination causes the shrimp paste inside the container to slowly slide and shift under the action of gravity, and finally form a stacked or abutted situation. Summary of the Invention

[0028] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following provides a detailed description of the specific implementation manners of the present invention with reference to the accompanying drawings of the specification.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0030] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments.

[0031] Embodiment 1 Refer to Figures 1 to 8 , which is the first embodiment of the present invention. This embodiment provides a cold transportation device for shrimp paste. By means of the driving piece 225 and the vibration piece 227, the storage piece 21 is shaken back and forth and vibrated up and down. The dual movements ensure that the shrimp paste is evenly dispersed, not only effectively preventing freezing and adhesion, but also enabling a uniform ice shell to form on the surface, improving the freezing protection effect of the shrimp paste.

[0032] Specifically, the freezing component 1 includes a freezer 11 and a guide rail 13 provided on the inner wall of the freezer 11. The freezer 11 enables the shrimp paste to remain in a frozen state continuously during transportation, effectively extending the shelf life of food.

[0033] The storage component 2 includes a storage member 21 disposed inside the freezer 11, a protection member 22 disposed at the bottom of the storage member 21, and a protection member 23 disposed at the top of the storage member 21. The storage member 21 enables the layered placement of shrimp paste in the freezer 11, improving the storage density. The protection member 22 is used to prevent damage to the shrimp paste caused by jolts during transportation, ensuring the integrity of its appearance and taste. The protection member 23 is used to prevent impurities from contaminating the surface of the shrimp paste, ensuring the safety and hygiene of the food.

[0034] The protection member 22 includes a tray 221 corresponding to the guide rail 13 and having a limit groove 222, a support member 226 disposed between the storage member 21 and the tray 221, a driving member 225 disposed in the limit groove 222, and a vibrating member 227 disposed on the top of the tray 221 and connected to the driving member 225. The tray 221 is used to collect the water droplets dripping from the shrimp paste in the storage member 21, preventing it from affecting the freezer 11 and other storage components 2. The support member 226 elevates the storage member 21 to form a gap with the tray 221, facilitating the cold air in the freezer 11 to pass through the periphery of the storage member 21, thereby accelerating the freezing of the shrimp paste. The tray 221 slides down along the guide rail 13 with the limit groove 222 to be placed in the freezer 11, ensuring that the storage member 21 remains horizontal during the placement process, effectively preventing the shrimp paste in the storage member 21 from stacking together. The driving member 225 cooperates with the guide rail 13 to perform a linear reciprocating motion to provide a power source, and then drives the vibrating member 227 to perform a periodic motion.

[0035] When the tray 221 moves along the guide rail 13 with the limit groove 222, the driving member 225 reciprocally pushes the storage member 21, and at the same time, the driving member 225 reciprocally vibrates the storage member 21 through the vibrating member 227. The support member 226 enables the movement of the storage member 21 relative to the tray 221, and the driving member 225 enables the reciprocating movement of the storage member 21, thereby periodically shaking the shrimp paste in the storage member 21 back and forth. The vibrating member 227 enables the periodic vibration of the storage member 21, thereby periodically jittering the shrimp paste in the storage member 21 up and down. The cooperation of the driving member 225 and the vibrating member 227 can effectively prevent the shrimp paste from stacking together during the placement in the freezer 11, avoiding the shrimp paste from freezing and sticking into blocks, and maintaining its independence and separability.

[0036] Further, a cabinet door 12 is hingedly provided on the top side wall of the freezer 11. The surface profile of the guide rail 13 is a wavy contour, and the surface profiles of the guide rails 13 at both ends inside the freezer 11 are mutually consistent. The driving member 225 realizes a linear reciprocating motion through the surface of the guide rail 13.

[0037] It should be noted that the driving member 225 includes a sliding rod 2251 that penetrates through the side wall of the tray 221. A support 2252 is provided between the top of the tray 221 and the vibrating member 227 within the limiting groove 222. The inner end of the sliding rod 2251 slides through the support 2252 and is connected to the vibrating member 227. The outer end of the sliding rod 2251 is located inside the limiting groove 222 and is connected with a ball head 2255. The ball head 2255 slides down along the surface of the guide rail 13, thereby driving the sliding rod 2251 to perform linear reciprocating motion. The contact surface of the ball head 2255 reduces the frictional resistance. The support 2252 ensures the movement track of the sliding rod 2251, and further, the sliding rod 2251 provides a power source.

[0038] The vibrating member 227 includes a bracket 2271 connected to the top surface of the tray 221. The upper end of the bracket 2271 is hinged with a connecting rod 2272. The lower end of the connecting rod 2272 at the hinge point is longer than the upper end of the connecting rod 2272 at the hinge point. The bottom end of the connecting rod 2272 is connected to the inner end of the sliding rod 2251. The side wall of the upper end of the connecting rod 2272 is connected with an eccentric block 2273. The sliding rod 2251 drives the connecting rod 2272 to perform a lever motion relative to the bracket 2271. Since the lower end of the connecting rod 2272 is longer than the upper end, the force applied by the sliding rod 2251 is amplified. The connecting rod 2272 impacts and pushes the storage member 21 with the eccentric block 2273, and the storage member 21 vibrates up and down to prevent the shrimp paste from stacking.

[0039] During use, the operator neatly places the shrimp paste in the storage member 21. The shrimp paste needs to be initially laid flat in the container without excessive arrangement. Subsequently, the tray 221 slides down along the wavy guide rail 13 with the limiting groove 222, so that the entire storage assembly 2 smoothly slides into the interior of the freezer 11. The movement of the tray 221 ensures that the storage member 21 always remains horizontal during the entire placement process, preventing the shrimp paste from stacking due to inclination. During the sliding process, the ball head 2255 slides along the curved surface of the guide rail 13, and the linear reciprocating motion is transmitted to the vibrating member 227 through the sliding rod 2251. During this process, the driving member 225 realizes the front-back shaking of the storage member 21. At the same time, the vibrating member 227 generates periodic vibrations in the up-down direction under the movement of the sliding rod 2251, causing the shrimp paste to perform dual movements before freezing. The front-back shaking prompts the stacked or aggregated shrimp paste to naturally disperse, and the up-down vibration helps to shake off the excess moisture on the surface of the shrimp paste, enabling it to evenly form a protective ice shell, thereby avoiding agglomeration during the freezing process without additional manual intervention, greatly improving the freezing efficiency and quality.

[0040] In summary, in this embodiment, the shrimp paste realizes a horizontal sliding movement during the process of being placed into the freezer 11, effectively preventing the shrimp paste from stacking due to human-induced inclination. At the same time, under the action of the curved surface of the guide rail 13, the sliding rod 2251 drives the storage member 21 to shake back and forth, and together with the eccentric connecting rod 2272 and the eccentric block 2273, the storage member 21 is driven to vibrate up and down. The dual movements ensure that the shrimp paste is evenly dispersed, not only effectively preventing freezing adhesion, but also enabling a uniform ice shell to form on the surface, improving the freezing protection effect of the shrimp paste. The power for sliding depends entirely on the self-weight of the shrimp paste and the device, without the need for additional power input, and it has good energy-saving performance and practicality.

[0041] Embodiment 2 Refer to Figures 3 to 7 , which is the second embodiment of the present invention. Different from the previous embodiment, in this embodiment, the structures of the storage member 21 and the support member 226 are further optimized to keep the shrimp paste in a dispersed state during vibration, avoid stacking and freezing into blocks, and enhance the cooling efficiency of the storage member 21.

[0042] Specifically, the storage member 21 includes a net box 211 disposed above the top surface of the tray 221. A retaining bar 213 is provided at the inner bottom of the net box 211. An installation hole 214 is opened on the outer wall of the net box 211 directly above the support member 226. The porous structure of the net box 211 is conducive to the cold air in the freezer 11 passing through the shrimp paste. The retaining bar 213 first enhances the structural strength of the net box 211, and secondly, prevents the shrimp paste from closely adhering to the inner bottom surface of the net box 211. The retaining bar 213 leaves a gap between the shrimp paste and the inner bottom surface of the net box 211, which is conducive to the cold air passing through the shrimp paste.

[0043] The support member 226 includes a support spring 2261 vertically disposed between the net box 211 and the tray 221. A base 2262 is provided on the top surface of the tray 221 at the bottom end of the support spring 2261. A fixing buckle 2263 connected to the installation hole 214 is provided at the top end of the support spring 2261. The support spring 2261 provides a support force for the net box 211, and the support spring 2261 can simultaneously shake back and forth and stretch up and down, providing a basic support for the dual movements of the net box 211. The fixing buckle 2263 is conducive to the disassembly and assembly of the net box 211.

[0044] Further, a positioning ring 2253 is provided on the outer wall of the sliding rod 2251. A connecting frame 212 is provided at the bottom of the net box 211 above the positioning ring 2253. The upper end of the positioning ring 2253 is movably clamped inside the connecting frame 212. The sliding rod 2251 drives the net box 211 to shake periodically with the positioning ring 2253.

[0045] The positioning ring 2253 is located on one side of the outer end of the support 2252. A return spring 2254 is connected between the inner end face of the positioning ring 2253 and the outer end face of the support 2252. The return spring 2254 is wound around the outer surface of the slide bar 2251. The return spring 2254 enables the automatic return of the slide bar 2251 and realizes its linear reciprocating motion.

[0046] All other structures are the same as those in Embodiment 1.

[0047] During use, the operator places the shrimp paste in the net box 211. With the help of the stop bar 213, the shrimp paste can be prevented from closely adhering to the inner bottom surface of the net box 211, leaving a gap between the shrimp paste and the inner bottom surface of the net box 211, which is conducive to the cold air of the freezer 11 passing through the shrimp paste. The support spring 2261 provides flexible support for the net box 211, enabling it to move up and down during the shaking process. The slide bar 2251 periodically shakes the net box 211 through the positioning ring 2253, preventing the shrimp paste from freezing into lumps during the freezing process.

[0048] In summary, the net box 211 in combination with the stop bar 213 enables the cold air of the freezer 11 to pass through the shrimp paste as much as possible, improving the freezing efficiency of the freezer 11 for the shrimp paste. The support spring 2261 provides flexible support for the net box 211, thereby laying the foundation for the double movement of the net box 211. The fixed buckle 2263 is conducive to the disassembly and assembly of the net box 211, and the positioning ring 2253 and the return spring 2254 ensure the reciprocating movement of the slide bar 2251.

[0049] Embodiment 3 Refer to Figure 3 、 Figure 5 and Figure 6 , which is the third embodiment of the present invention. Different from the previous embodiment, the structure of the protective member 23 is further optimized in this embodiment, improving the storage hygiene of the shrimp paste and also helping the shrimp paste to be evenly distributed during storage.

[0050] Specifically, the protective member 23 includes a cover plate 231 hinged to the top of one end of the tray 221. The cover plate 231 covers the top of the net box 211 and forms a gap. The bottom of the cover plate 231 is provided with isolation sheets 232 in an array. The lower ends of the isolation sheets 232 are located at the upper end inside the net box 211. The bottom of the isolation sheets 232 is provided with wire grooves 233. The cover plate 231 is hinged and rotated relative to the tray 221 to complete the opening and closing. The cover plate 231 does not affect the placement of the shrimp paste in the net box 211. After the cover plate 231 is closed, it prevents external impurities from contaminating the shrimp paste. The cover plate 231 is connected to the tray 221. Thus, when the net box 211 moves, the isolation sheets 232 remain stationary, and the isolation sheets 232 flatten the shrimp paste.

[0051] Further, shock absorbers 224 are connected and arranged at the top of each end corner of the tray 221. The top surface of the shock absorber 224 is higher than the top surface of the cover plate 231. Grips 223 are symmetrically connected and arranged at the top of both sides of the tray 221. The grips 223 are conducive to the operator's taking and placing of the storage assembly 2.

[0052] All the other structures are the same as those in Embodiment 2.

[0053] During use, the operator first opens the cover plate 231, neatly arranges the pre-treated shrimp paste into the net box 211. After the cover plate 231 is closed, it prevents the pollution of external impurities. When the net box 211 is moving, the cover plate 231 and the isolation sheet 232 remain stationary, ensuring that during the vibration and dispersion process of the shrimp paste, it is always separated by the isolation sheet 232, inhibiting its re-stacking and aggregation. The shock absorber 224 provides buffer protection, and the grip 223 provides a convenient grasping point during the operation process, preventing the sliding and accumulation of the shrimp paste.

[0054] In summary, the cover plate 231 improves the sanitary protection ability of the shrimp paste during refrigerated transportation, and also uses the isolation sheet 232 for the uniform distribution of the shrimp paste. At the same time, the settings of the shock absorber 224 and the grip 223 on the tray 221 improve the impact resistance performance and operation convenience of the storage assembly 2.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
