Description

Technical Field

[0001] The invention relates to the technical field of seafood transportation devices, in particular to a micro-frozen transportation device for whiteleg shrimps which is convenient for classification. Background Art

[0002] Penaeus vannamei is a decapod Penaeididae genus animal, also known as white shrimp, white shrimp. Penaeus vannamei has a thin carapace, a light blue-gray body color, and small spots on the body surface; the length of the frontal horn tip does not exceed the second section of the first antennal handle; the side groove of the frontal horn is short and disappears below the stomach spine; the cephalothorax is short, with liver spines and gill horn spines; the 4th to 6th abdominal segments have dorsal ridges; the tail segment has a central groove, but no marginal spines. The average lifespan of Penaeus vannamei is more than 32 months. Penaeus vannamei is mainly distributed along the Pacific coast of America. It is the main aquaculture species in Ecuador and other American countries. It is also cultivated in the Yellow Sea and Bohai Sea of ​​China. Penaeus vannamei is a tropical shrimp with wide temperature and salt content, and often lives on muddy seabeds. It crawls on the ground or lurks on the surface of the seabed during the day, and is active at night. Adult shrimps mostly live in coastal waters close to the shore, while juvenile shrimps prefer to feed and grow in estuaries with abundant bait organisms. Since white shrimps are seafood products, they usually require long transportation. In order to ensure the freshness of white shrimps, a transfer device is usually required.

[0003] However, the existing micro-frozen transfer device for white shrimp that is easy to classify still has certain problems when used: There is a frozen seafood turnover box with a Chinese patent publication number of CN210794301U, in which the top of the box is open, the limiting structure is arranged close to the angle between the bottom plate and the side plate of the box, and the two limiting structures are arranged opposite to each other in the box, and a step structure is arranged on the side of the limiting structure facing the inside of the box, the step structure includes a first step surface located in the middle of the step structure and a second step surface located at the top of the step structure, the partition is overlapped on the first step surface, and the freezing box is overlapped on the second step surface, so that the inside of the box is divided into a first compartment, a second compartment and a third compartment arranged from bottom to top by the partition and the freezing box, the partition is a mesh structure with frames on all sides, and the freezing box is a hollow flat box; but there are still some problems with the existing transfer device; The existing turnover box is mainly used for heat preservation. Although it has a good heat preservation effect, it usually needs to rely on cold sources such as ice cubes or ice bags. Such cold sources cannot ensure that the internal temperature is uniform. If the white shrimp is directly in contact with the cold source, the meat taste will deteriorate after partial freezing. In addition, the cold source has a limited cooling time. If an emergency occurs during transportation and affects the transportation time, the cold source can no longer continue to provide cooling, and the white shrimp inside will also deteriorate due to the increase in temperature, which is likely to cause greater economic losses. Most of the existing transfer devices are freezing equipment. Compared with seafood and other products, the taste cannot be guaranteed after freezing, and the freshness is relatively poor compared with micro-freezing equipment, which will inevitably cause the quality of white shrimp to be poor and affect the subsequent sales profit; Most existing refrigeration devices cannot ensure uniform temperature inside the box. If the temperature is too high or too low locally, it will affect the quality of the white shrimp.

[0004] In view of the above problems, an innovative design was made based on the original micro-frozen transfer device for whiteleg shrimp which is easy to classify. Summary of the invention

[0005] The object of the present invention is to provide a slightly frozen transfer device for whiteleg shrimp that is easy to classify, so as to solve the problem that most of the existing whiteleg shrimp transfer devices mentioned in the above background technology cannot control the temperature themselves, and the internal temperature cannot be guaranteed to be uniform. Due to temperature differences and the like, the quality of the whiteleg shrimp is affected, thereby affecting the subsequent sales profit.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a slightly frozen transport device for whiteleg shrimp that is easy to classify, comprising a transport box: The transfer box is provided with side handles on the left and right sides, and a sealing cover is snap-connected at the upper end of the transfer box, two sets of upper handles are connected to the middle of the upper end of the sealing cover, two sets of positioning tubes are connected to both sides of the transfer box, and a sealing tube is passed through the lower end of the positioning tube, and a suction cup support leg is connected to the bottom end of the sealing tube; A temperature conducting pipe is arranged inside the transfer box, and a middle partition net is connected to both sides of the middle of the transfer box.

A buffer spring is provided inside the positioning tube, and the lower end of the buffer spring is fixedly connected to the upper end of the sealing tube.

[0008] By adopting the above technical solution, through the cooperation between multiple groups of positioning tubes, buffer springs and sealing tubes, a certain buffering effect can be provided for the transfer box after the suction cup support legs come into contact with the ground.

[0018] By adopting the above technical solution, through the setting of the transmission shaft, when the sealing tube moves toward the inside of the positioning tube when the transport box is bumpy, the distance between the transport box and the ground changes, thereby driving the transmission shaft to move toward the inside of the transport box, and driving the transmission rack to move, thereby driving the second pulley to rotate through the transmission gear, providing power for the rotation of the fan blades, without the need to set up a separate power source, relying on the bumps in the transportation process to be converted into kinetic energy, further providing a transfer space with a more uniform temperature for the white shrimp.

[0019] Preferably, a fixed block is embedded in the middle of the transfer box, and a rotating shaft passes through the middle of the fixed block, and the rotating shaft passes through the middle partition, a power motor is clamped and installed inside the middle partition, and the power motor is fixedly connected to the rotating shaft, a movable groove is opened inside the fixed block, and a guide hose is arranged inside the movable groove; The outer end of the rotating shaft is fixedly connected with a rotating block, and the rotating block is designed to be a triangular structure, and the corners of the rotating block are axially connected with extrusion rollers.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: the micro-frozen transport device for whiteleg shrimp that is easy to classify is convenient for accurately controlling the internal temperature of the box by providing a semiconductor refrigeration plate structure and cooperating with a flowable temperature-conducting liquid, thereby ensuring that the whiteleg shrimp has the best transportation temperature and freshness, preventing the whiteleg shrimp from having a deterioration in taste and quality due to freezing at too low a temperature, and cooperating with an air circulation structure and a temperature-conducting liquid circulation structure, it can ensure that the temperature inside the transport box is more uniform, further ensuring the quality of the whiteleg shrimp.

[0024] 1.

By setting up a liquid circulation structure, the temperature-conducting liquid cooled by the semiconductor refrigeration plate can be circulated to ensure uniform internal temperature, so that the transfer box itself has a thermal insulation effect. If special circumstances occur and it is unable to continue to provide cooling, the temperature of the temperature-conducting liquid circulating inside is relatively low. Combined with the insulated transport box, it can also extend the shelf life and further reduce risks and economic losses. BRIEF DESCRIPTION OF THE DRAWINGS
