Description

Technical Field

[0001] This utility model relates to the field of shrimp and crab farming technology, specifically to a nest for centralized shrimp and crab farming. Background Technology

[0002] Shrimp and crabs have a very close relationship with humans. Some are major aquaculture or fishing targets, especially shrimp, lobsters and crabs. Humans use various tools to help with the farming of shrimp and crabs.

[0003] In the existing shrimp and crab farming process, since the chances of shrimp and crab larvae surviving on their own are small, they need to be artificially cultivated in advance. After the shrimp and crab larvae have the ability to survive on their own, they are then released into the breeding pond in large numbers. The breeding boxes for shrimp and crab larvae are generally only single-layered, and the space inside the breeding boxes is small. In addition, when feeding the shrimp and crab larvae, uneven feeding will cause some shrimp and crab larvae to be unable to eat, which will reduce the survival rate of the larvae. Utility Model Content

[0004] The purpose of this invention is to provide a intensive shrimp and crab farming nest to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shrimp and crab intensive farming nest, comprising two farming boxes, wherein multiple vertically stacked farming cages are installed inside the farming boxes, and multiple horizontally arrayed hexagonal through holes are formed inside the farming cages. A partition box is installed between the two farming boxes, and a grid is installed at both the front and rear ends of the partition box. Multiple rotating shafts of different heights are horizontally installed inside the partition box, and multiple rotating blades are arrayed on the surface of the rotating shafts. The rotating shafts are connected to an external drive device.

[0006] Preferably, the breeding cage includes an upper mounting plate and a lower mounting plate. The upper mounting plate and the lower mounting plate have the same structure and size and are oriented in opposite directions. The shape of multiple upper mounting plates and lower mounting plates stacked together is honeycomb-like.

[0007] Preferably, the breeding box includes a reinforcing plate and a bottom plate, with a reinforcing plate snapped into each of the left and right sides of the upper end of the bottom plate, and the inner side of the reinforcing plate snapping into one end of the breeding cage.

[0008] Preferably, the reinforcing plate has multiple mounting slots of different heights evenly distributed at one end facing the breeding cage, and the dimensions of the mounting slots are consistent with the dimensions of the left and right ends of the breeding cage.

[0009] Preferably, the inside of the breeding box has multiple vertically stacked feeding structures slidably connected to one end near the partition box, and two sets of feeding structures are connected by two connecting auxiliary rods, and a connecting main rod is connected between the two connecting auxiliary rods.

[0010] Preferably, a groove is provided on the inner side of each of the two reinforcing plates, and the groove is slidably connected to the feeding structure.

[0011] Preferably, the feeding structure includes a connecting plate and a feeding trough, the interior of the trough is slidably connected to the connecting plate, a feeding trough is installed between the two connecting plates, and a connecting auxiliary rod is installed between the two uppermost connecting plates.

[0012] Preferably, a through hole is provided on the upper part of the left and right side walls of the breeding box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This shrimp and crab intensive breeding nest uses multiple vertically stacked breeding cages connected inside the breeding box to form a honeycomb structure. The cages have multiple hexagonal through-holes of varying heights to hold shrimp and crab larvae. Two breeding boxes are then connected by a partition box. The connected breeding boxes and partition box are placed inside the cultivation box, where shrimp and crab larvae are placed through the hexagonal through-holes, making more efficient use of the cultivation box's internal space. A rotating shaft drives multiple rotating blades, causing a slow water flow inside the cultivation box, accelerating oxygen circulation and improving the survival rate of the shrimp and crab larvae.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1 to 5As shown, the shrimp and crab intensive farming nest in this embodiment includes two farming boxes 1, which are identical in size and material. Multiple vertically stacked farming cages 3 are installed inside each farming box 1, forming a honeycomb structure. The interior of each farming cage 3 has multiple horizontally arrayed hexagonal through-holes. These hexagonal through-holes provide high stability and can be used for the survival of shrimp and crab larvae. These through-holes divide the internal space of the farming box 1 into multiple layers of varying heights, allowing for the cultivation of more shrimp and crab larvae. A partition box 2 connects the two farming boxes 1. Together, they also serve as a partition. Both the front and rear ends of the partition box 2 are equipped with a grid 10. The grid 10 can prevent shrimp and crab larvae inside the breeding box 1 from entering the interior of the partition box 2. Inside the partition box 2, multiple rotating shafts 11 of different heights are installed horizontally. Multiple rotating blades 4 are arrayed on the surface of the rotating shafts 11. The rotating shafts 11 are connected to an external drive device, which drives the rotating shafts 11 to rotate. The rotating shafts 11 drive the multiple rotating blades 4 to rotate slowly, thereby accelerating the flow of water inside and increasing the contact frequency between water and air, so that the oxygen flow inside the breeding box is more balanced.

[0026] Specifically, the breeding cage 3 includes an upper mounting plate 301 and a lower mounting plate 302. The upper mounting plate 301 and the lower mounting plate 302 have the same structure and size but are oriented in opposite directions. The shape of multiple upper mounting plates 301 and lower mounting plates 302 stacked together is honeycomb-like, such as... Figure 2 As shown, the upper mounting plate 301 and the lower mounting plate 302 are connected to each other to form a complete breeding cage 3. The interior of a complete breeding cage 3 has multiple hexagonal through holes, and the interior of a breeding box 1 contains multiple breeding cages 3.

[0027] Furthermore, the breeding box 1 includes a reinforcing plate 101 and a bottom plate 102. A reinforcing plate 101 is snapped onto each of the left and right sides of the upper end of the bottom plate 102. The inner side of the reinforcing plate 101 is snapped onto one end of the breeding cage 3. Since the breeding cage 3 is formed by snapping together two identical components, it is easy for it to separate after being placed for a long time. By reinforcing both ends of the breeding cage 3 with two reinforcing plates 101, the separation of the breeding cage 3 can be prevented.

[0028] Furthermore, the reinforcing plate 101 has multiple mounting slots 5 of different heights evenly opened on one end facing the breeding cage 3. The size of the mounting slots 5 is consistent with the size of the left and right ends of the breeding cage 3. During the installation process, the left and right ends of the breeding cage 3 are respectively inserted into the mounting slots 5 inside the reinforcing plate 101. It should be noted that the number of mounting slots 5 is consistent with the number of breeding cages 3.

[0029] Furthermore, multiple vertically stacked feeding structures 7 are slidably connected to one end of the breeding box 1 near the partition box 2. Two sets of feeding structures 7 are connected by two connecting auxiliary rods 9, and a connecting main rod 8 is connected between the two connecting auxiliary rods 9. By vertically stacking and connecting multiple feeding structures 7 in sequence, a set of feeding structures 7 is formed. The two sets of feeding structures 7 are connected together by the two connecting auxiliary rods 9, and then the two connecting auxiliary rods 9 are connected together by the connecting main rod 8. The two sets of feeding structures 7 are placed inside the two breeding boxes 1 through the connecting main rod 8. The multiple feeding structures 7 are at different heights, which allows the feed to be more comprehensively distributed in different areas of the breeding box 1.

[0030] Furthermore, a groove 6 is provided on the inner side of each of the two reinforcing plates 101. The groove 6 is slidably connected to the feeding structure 7. By sliding the feeding structure 7 inside the groove 6, the position of the feeding structure 7 is limited. It should be noted that the groove 6 is a vertical groove 6.

[0031] Furthermore, the feeding structure 7 includes a connecting plate 701 and a feeding trough 702. The interior of the chute 6 is slidably connected to the connecting plate 701. A feeding trough 702 is installed between the two connecting plates 701. A connecting rod 9 is installed between the two uppermost connecting plates 701. The feeding trough 702 is used to place bait. The two connecting plates 701 are installed at both ends of the feeding trough 702. Multiple connecting plates 701 are installed and stacked together, so that multiple feeding structures 7 can be stacked vertically together.

[0032] Furthermore, a through hole 12 is provided on the upper part of the side walls at both ends of the breeding box 1, such as... Figure 1 and Figure 4 As shown, through holes 12 are formed on the side wall of the breeding box 1. The size of the through holes 12 can be modified according to the user's needs. The user can use ropes or chains to pass through the through holes 12 and pass through multiple breeding boxes 1 in sequence. Multiple breeding boxes 1 can be connected together by chains, which makes it convenient for the user to reasonably organize the breeding space.

[0033] The method of use in this embodiment is as follows: Multiple vertically stacked breeding cages 3 are snapped into the inside of the breeding box 1, forming a honeycomb structure between the multiple breeding cages 3, and there are multiple hexagonal through holes of different heights inside for placing shrimp and crab larvae. Then, two breeding boxes 1 are connected by a partition box 2. The two connected breeding boxes 1 and the partition box 2 are placed inside the cultivation box. Shrimp and crab larvae are placed through multiple hexagonal through holes of different heights, making more efficient use of the space inside the cultivation box. Then, the rotating shaft 11 drives multiple rotating blades 4 to rotate, causing the water inside the cultivation box to flow slowly, accelerating the flow of oxygen inside the cultivation box, and improving the survival rate of shrimp and crab larvae.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
