[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] This utility model provides a laboratory shellfish culture box; please refer to the attached instruction manual. Figure 1 To be continued Figure 4The laboratory shellfish culture box includes a container 1 for holding shellfish to be cultured. A top plate 2 is detachably mounted at the port of the container 1. Several ventilation holes 23 are evenly distributed along the edge of the top plate 2. A support rod 3 is inserted through the center of the top plate 2, perpendicular to the top plate 2 and extending into the inner cavity of the container 1. Threads are provided on the side wall of the section of the support rod 3 within the cavity. Several trays 4 are mounted on the threaded section of the support rod 3, and these trays 4 are parallel to each other. Several drainage holes 41 are provided on the end face of each tray 4, and these drainage holes 41 are evenly distributed around the support rod 3. In one embodiment of the application, the top plate 2 is separated from the container 1, and an appropriate amount of culture medium is poured into the container 1. Different types of shellfish to be cultured are placed on trays 4 in different layers. Each tray 4 is rotated according to its size, and slides along the support rod 3 to adjust the spacing between adjacent trays 4, ensuring sufficient and suitable growth space for each shellfish. When the cultured shellfish need to be removed, the top plate 2 is removed from the container 1, and the top plate 2, along with the support rod 3, is moved out of the container 1. The drainage holes 41 on each tray 4 guide the culture solution into the container 1, preventing the culture solution from accumulating on the trays 4 and affecting the sampling of the shellfish. Furthermore, the drainage holes 41 alleviate the resistance encountered by the trays 4 during lifting, preventing the culture solution from washing some shellfish off the trays 4. This invention arranges the trays 4 evenly along the support rod 3, allowing each tray 4 to vertically utilize the space inside the container 1, improving the space utilization rate of the container 1. Rotating the trays 4 to move them along the support rod 3 and adjusting the spacing between adjacent trays 4 according to the type or size of the shellfish on the trays 4 improves the applicability of this application.

[0023] Please refer to the instruction manual appendix. Figure 2The top plate 2 includes a fixed plate 22 that engages with the port of the receiving box 1. A movable plate 21 is provided on the edge of the fixed plate 22. The movable plate 21 is connected to the fixed plate 22 via a hinge 5, allowing the movable plate 21 to rotate around the edge of the fixed plate 22. Preferably, each hinge 5 includes two connecting plates 51, symmetrically distributed on both sides of the edge where the movable plate 21 and the connecting plates 51 meet. The connecting plates 51 are located on the end face of the top plate 2 facing away from the inner cavity of the receiving box 1. A hinge pin 52 passes through each connecting plate 51. The connecting plates 51 drive the movable plate 21 to rotate around the hinge pin 52. Since the connecting plates 51 are located on the side of the top plate 2 facing away from the port of the receiving box 1... The movable plate 21 can only be flipped to the side with the connecting plate 51. When the movable plate 21 is not flipped, it tends to fall downwards due to its own weight. At the same time, the connecting plates 51 pull the movable plate 21 to lock its position. The movable plate 21 and the fixed plate 22 are on the same plane, covering the end of the container 1 to prevent external debris from affecting the breeding environment of the shellfish. When the operator feeds the shellfish breeding box in the laboratory regularly, it is only necessary to flip the movable plate 21 to the side away from the inner cavity of the container 1 so that the top of the container 1 has a sufficient feeding opening. After feeding, the movable plate 21 is reset, which optimizes the operation steps of shellfish breeding.

[0024] Preferably, a baffle 42 extends from the edge of each tray 4 towards the side closer to the top plate 2. The baffle 42 is annular, and its diameter increases towards the side away from the tray 4, making the baffle 42 a frustum. When each tray 4 is lifted by the support rod 3, the baffle 42 at the edge of the tray 4 prevents some shellfish from falling off the tray 4 due to the impact of the water flow. In addition, when the operator feeds the food, the inclined baffle 42 can guide the food into the tray 4, facilitating the feeding operation. Preferably, the tray 4 has a connection hole that mates with the support rod 3. The connection hole is threaded with the support rod 3. A guide cylinder 43 extends from the edge of the connection hole near the top plate 2. The inner wall of the guide cylinder 43 is threaded, which can also mate with the support rod 3. The guide cylinder 43 increases the bearing area of ​​the support rod 3 and the tray 4, making the tray 4 and the support rod 3 more stably matched. This prevents the support rod 3 from being unable to offset the bending moment generated by the weight of the tray 4, causing the tray 4 to tilt and affecting the stratified cultivation of shellfish.

[0025] To facilitate observation of the growth of various shellfish in the breeding tank, one side wall of the housing 1 is set as an observation plate 6. The observation plate 6 is made of transparent material. Preferably, the observation plate 6 can be any one of transparent acrylic plate or glass plate. In addition, the observation plate 6 is located on the side of the housing 1 near the movable plate 21. That is, when the operator opens the movable plate 21 and puts feed into the housing 1, the operator can face the observation plate 6 and observe more clearly whether the feed in each tray 4 has been put in place. The operator can also periodically check the growth of the shellfish through the observation plate 6. In addition, apart from the observation plate 6 and the top plate 2, the other side walls of the housing 1 are all light-shielding plates 7. The light-shielding plates 7 are made of opaque material and provide a weak light or no light growth environment for the shellfish.

[0026] Please refer to the instruction manual appendix. Figure 4 A fixing part 31 extends from the end of the support rod 3 away from the inner cavity of the container 1. The fixing part 31 is coaxially arranged with the support rod 3, and the diameter of the fixing part 31 is slightly larger than the diameter of the support rod 3. During the connection of the support rod 3 and the top plate 2, the support rod 3 is screwed so that the end face of the fixing part 31 near the support rod 3 abuts against the end face of the top plate 2, ensuring a stable connection between the support rod 3 and the top plate 2. Preferably, the side wall of the fixing part 31 is provided with friction texture. In one embodiment of this application, the operator grips and lifts the fixing part 31, and the fixing part 31 moves together with the top plate 2 and the support rod 3 to move the tray 4 out of the container 1 for subsequent shellfish sampling.

[0027] Preferably, each tray 4 is provided with a buckle on the side away from the guide cylinder 43. Each buckle is clamped on both sides of the support rod 3 to prevent the tray 4 from twisting along the thread due to its own weight, changing the distance between the trays 4, and preventing the tray 4 from pressing on the shellfish and causing damage to the shellfish.

[0028] When culturing shellfish using this application, some species of shellfish produce secretions for self-fixation. For example, mussels secrete byssal threads from their abdomen during cultivation. These byssal threads adhere to the tray 4 or the support rod 3. When the byssal threads adhere to the support rod 3, they damage the threaded structure of the outer wall of the support rod 3. Operators cannot twist the tray 4 when removing it or adjusting the spacing between the trays 4, which affects the experimental process. Therefore, during the process of screwing the tray 4 onto the support rod 3, several telescopic tubes (not shown in the figure) are fitted onto the support rod 3. Preferably, the sidewall of the telescopic tube is threaded, and each layer of the threaded tube can be folded. Each telescopic tube is located between adjacent trays 4 and between the tray 4 and the top plate 2. The length of the telescopic tube can be changed along with the spacing between the trays 4. During the growth of the shellfish, the byssal threads attached to the telescopic tube do not damage the threaded structure of the support rod 3. The spacing between each tray 4 can still be adjusted by screwing. When the shellfish culture is completed and sampling is carried out, the tray 4 is removed from the support rod 3, and the telescopic tube along with the shellfish that are attached to it is removed together.

[0029] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0030] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
