Description

Technical Field

[0001] The utility model relates to the technical field of fish breeding, in particular to a small fish breeding device. Background Art

[0002] Small Siluriformes fish (such as white-margined catfish, black-tailed catfish, cold-water catfish) are similar to eels and loaches, and usually like to live in nests. Therefore, when breeding small Siluriformes fish, tools similar to artificial eel nests are usually used to provide habitats for fish. However, the inside of the eel nest is wrinkled (i.e., it has a certain curvature). However, the body of small Siluriformes fish cannot be twisted significantly like eels and loaches, so it cannot turn in the eel nest and is easy to get stuck in the nest and die. Therefore, how to provide a breeding device to prevent the fish from getting stuck in the nest due to the inability of the fish body to twist significantly is a technical problem to be solved in this field. Utility Model Content

[0003] The utility model aims to provide a small fish breeding device to prevent the fish from getting stuck in the nest due to the inability of the fish body to twist significantly.

[0026] Embodiment 1

[0027] refer to Figure 1 A small fish breeding device includes a support rod 2 and a plurality of nesting plates 1. A plurality of linear half grooves 101 are arranged at intervals on both sides of the thickness direction of the nesting plates 1. The plurality of nesting plates 1 are sequentially sleeved on the support rod 2. In this embodiment, a support rod 2 is arranged at each end of the nesting plate 1. Of course, in other embodiments, multiple support rods 2 are arranged at each end. A stopper 5 is arranged at both ends of the support rod 2. The stopper 5 can be connected to the two ends of the support rod 2 by threads. In actual applications, the stopper 5 can be replaced by a nut.

[0028] The nesting plate 1 and the support rod 2 together form a nesting box for breeding small fish, which can be fixed in the breeding pond. The two half grooves 101 at the corresponding positions on the adjacent sides of the adjacent nesting plates 1 enclose a habitat channel 6. The half grooves 101 are linear, which prevents the fish from getting stuck in the habitat channel 6 due to the inability to twist its body significantly.

[0029] The half grooves 101 on both sides of the nest plate 1 are staggered, so that the thickness of the nest plate 1 can be greatly reduced and the weight can be reduced. In other embodiments, if the weight is not considered, of course, the half grooves 101 on both sides of the nest plate 1 can also be arranged relative to each other. In practical applications, the nest plate 1 is made of plastic or aluminum alloy, and is as light as possible. The half grooves 101 are polished and smooth to ensure that the fish can swim smoothly.

[0030] In this embodiment, the cross section of the half groove 101 perpendicular to the length direction is semicircular, so as to avoid corners on the bottom of the groove, that is, to avoid the fish food falling on the corners and being unable to be eaten by the fish during feeding, thereby causing the fish food to pile up. It is easy to understand that this is only an option of this embodiment, not a limitation. In other embodiments, of course, the cross section of the half groove 101 perpendicular to the length direction can also be designed into other shapes.

[0031] Embodiment 2

[0032] The difference between this embodiment and the first embodiment is that Figure 2 In this embodiment, a plurality of support members 4 are arranged at intervals on the support rod 2, each slot plate is supported by the support member 4, and the distance between two adjacent support members 4 is greater than the thickness of the nest plate 1, so that each nest plate 1 can move upward by a certain distance, thus preventing some larger fish from getting stuck in the habitat channel 6 and causing death.

[0033] The support member 4 is detachably connected to the support rod 2. Specifically, the support member 4 of this embodiment is disc-shaped and is connected to the support rod 2 by threads, that is, the support rod 2 is provided with external threads, and the support member 4 is provided with internal threads. It is worth noting that such a configuration enables the distance that the nesting plate 1 can move to be changed by changing the position of the support member 4. In practical applications, the support member 4 can be directly replaced by a nut for convenient screwing and adjustment.

[0034] refer to Figure 3 and Figure 4 In this embodiment, a support rod 2 is disposed at each end of the nest plate 1, and an auxiliary rod 3 is disposed at each corner of the nest plate 1. The auxiliary rod 3 is passed through the nest plate 1, and both ends of the auxiliary rod 3 are also provided with limit members 5. The auxiliary rod 3 can be a bare rod, which serves as an auxiliary support and auxiliary guide to facilitate a more stable structure.

[0035] Furthermore, the support rod 2 and the auxiliary rod 3 are hollow inside, that is, the support rod 2 and the auxiliary rod 3 are both tubular, which helps to reduce the overall weight.

[0036] Embodiment 3

[0037] The difference between this embodiment and the second embodiment is that the structure and arrangement of the support member 4 are different. Figure 5 and Figure 6 In this embodiment, the support member 4 includes a guide cylinder 401 and a support ring 402, which form a T-shaped cylinder structure, that is, one end is large and the other end is small, the support ring 402 is the large end, and the guide cylinder 401 is the small end. The support member 4 is sleeved on the support rod 2. Among the adjacent support members 4, the guide cylinder 401 of one support member 4 abuts against the support ring 402 of another support member 4. When assembling, the support member 4 and the nesting plate 1 are installed in the order of one support member 4 and one nesting plate 1. The nesting plate 1 is supported by the support ring 402 and slidably cooperates with the guide cylinder 401. When the nesting plate 1 is squeezed, it can move upward along the guide cylinder 401 for a certain distance.

[0038] In the figure, the support tube of the support member 4 is downward and the support ring 402 is upward. It is easy to understand that in other embodiments, the support tube can of course be upward and the support ring 402 can be downward.

[0039] It is worth noting that, in this embodiment, the distance that the nest plate 1 can move can be changed by replacing the support members 4 of different lengths. In addition, it is easy to understand that in this embodiment, the stopper 5 at the upper end of the support rod 2 can be directly replaced by the support member 4, and the support member 4 of this embodiment only needs to be provided with a thread at the upper end of the support rod 2 to connect with the uppermost support member 4, and no thread is required for other rod parts.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
