Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a multi-purpose shellfish seedling raising device. Background Technology

[0002] Traditional pearl mussel and other shellfish seedling cultivation uses a single water tap in each pond to supplement nutrients and oxygen.

[0021] 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.

[0022] The purpose of this invention is to provide a multi-purpose shellfish seedling raising device that avoids problems such as insufficient local nutrient supply, resulting in poor development, inconsistent size, and uneven specifications of some seedlings. It has more diversified functions and improves utilization rate and economic benefits.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1-2 As shown, this embodiment provides a multi-purpose shellfish seedling raising device 100, including a box body, a water level regulating mechanism, and multiple baffles. The upper end of the box body is an open structure. Multiple baffles are arranged alternately from left to right in the box body, forming a meandering flow channel in the box body. The two ends of the meandering flow channel are the inlet and the outlet, respectively. A water tap is installed above the inlet of the meandering flow channel. A drain outlet 13 is provided on the box body corresponding to the outlet position of the meandering flow channel. The water level regulating mechanism is installed at the drain outlet 13 to regulate the water level in the box body, thereby enabling the multi-purpose shellfish seedling raising device 100 to be used for shellfish seedling raising or other aquatic product cultivation.

[0025] During use, the water level in the tank is kept low by the water level adjustment mechanism to meet the needs of shellfish seedling cultivation. Bottom mud is laid in the tank, and then shellfish seedlings are placed in. Water is added through the inlet of the meandering flow channel, and the water flows throughout the entire tank in the meandering flow channel before being discharged through the drain outlet 13. This ensures that the seedlings in each area of ​​the tank can absorb fresh nutrients, avoiding problems such as insufficient local nutrient supply, which could lead to poor development, uneven size, and inconsistent specifications of some seedlings. This results in the production of high-quality shellfish seedlings that are of uniform size and well-developed.

[0026] During the non-seedling season, the water level in the tank is maintained at a high level through a water level adjustment mechanism to meet the aquaculture needs of other aquatic products. At this time, other aquatic products can be cultured in the tank, specifically, a batch of short-growing-cycle aquatic products such as snails, shrimp, and tropical fish can be raised. The water level adjustment mechanism allows the shellfish seedling cultivation device in this embodiment to simultaneously cultivate shellfish seedlings and other aquatic products at different times, realizing the dual-purpose nature of the shellfish seedling cultivation device, making its functions more diversified, avoiding idleness, improving the utilization rate of the shellfish seedling cultivation device, and increasing economic benefits.

[0027] The multi-purpose shellfish seedling raising device 100 in this embodiment can mimic the micro-dynamic water flow conditions of the natural breeding environment of shellfish to carry out off-season seedling raising, thereby surpassing traditional seedling raising technology in an artificially simulated environment and producing high-quality shellfish seedlings.

[0028] To facilitate seedling collection, each baffle in this embodiment is detachably mounted on the box. The detachable design of the baffles allows for easy removal of the baffles after the seedlings mature, enabling the use of a large, dense net to scoop out shellfish seedlings approximately 1 cm in size from inside the box.

[0029] The upper parts of both the front and rear sides of the enclosure are provided with slots for installing baffles. The slots on the upper front side of the enclosure and the slots on the upper rear side of the enclosure are staggered, and one end of each baffle is used to snap into a slot.

[0030] In this specific embodiment, a slot for installing a baffle plate is provided on the upper part of both the front and rear sides of the housing, and the two slots are staggered.

[0031] like Figure 2 As shown, the slot includes a strip groove and a connecting groove disposed inside the strip groove and perpendicular to each other. The connecting groove penetrates the inner wall of the box. The baffle includes a strip plate 7 and a water flow baffle 6 disposed perpendicularly on one side of the strip plate 7. The strip plate 7 is used to insert into the strip groove, and the end of the water flow baffle 6 near the strip plate 7 is used to insert into the connecting groove. The water flow baffle 6 can contact the bottom of the box.

[0032] This embodiment also includes a top limiting mechanism and two support plates 4. The two support plates 4 are respectively disposed on the left and right sides of the box. The two ends of the top limiting mechanism are respectively disposed on the two support plates 4 and are used to press against the upper part of multiple water flow baffles 6, so that the water flow baffles 6 contact the bottom of the box, preventing the water flow baffles 6 from floating up under the buoyancy of the water, and avoiding water flowing under the water flow baffles 6 and losing the water circulation function.

[0033] The top limiting mechanism includes a pressure strip 8 and two limiting components. A positioning plate 9 is provided on the upper part of both ends of the pressure strip 8. A groove for pressing the pressure strip 8 is provided on the upper part of each flow baffle 6. The two positioning plates 9 are respectively used to be placed on the upper part of the two support plates 4. The two limiting components are respectively set on the upper part of the two support plates 4. Each limiting component is used to limit one positioning plate 9.

[0034] The limiting component includes a fixing block and a pressure plate 12. The fixing block and the pressure plate 12 are located on both sides of the positioning plate 9. The fixing block includes a vertical plate 10 fixed on the support plate 4 and a horizontal plate 11 set on one side of the top of the vertical plate 10. The pressure plate 12 is rotatably installed on the support plate 4 via a rotating shaft. The pressure plate 12 can rotate to the top of the positioning plate 9, and its upper and lower sides can be tightly fitted with the horizontal plate 11 and the positioning plate 9 respectively, thereby limiting the positioning plate 9. By limiting the two positioning plates 9, the top of the pressure strip 8 is limited, so that the pressure strip 8 can be firmly pressed onto the upper part of the multiple water flow baffles 6.

[0035] In this embodiment, the multiple water flow baffles 6 are parallel to each other, and all of the multiple water flow baffles 6 are perpendicular to the pressure strip 8.

[0036] The lower part of the support plate 4 is provided with an arc-shaped groove 5 along its own length direction. The arc-shaped groove 5 matches the sliding support tube structure on the seedling support. A pull ring 19 is provided on the outside of the side of the box where the drainage outlet 13 is located.

[0037] By setting an arc-shaped sliding groove 5, the two support plates 4 can be slidably installed on the two sliding support tubes of the seedling frame. Furthermore, by setting a pull ring 19 on the outside of the box, it is easy to manually pull the box to slide on the sliding support tube, so as to facilitate inspection, management and seedling collection.

[0038] To facilitate the installation of the water level adjustment mechanism, the drain outlet 13 extends through the top of the housing, and slots 14 are provided on the two inner sides opposite to the drain outlet 13, into which the water level adjustment mechanism is inserted.

[0039] The water level regulating mechanism includes a water level regulating insert plate 15 and a water level regulating spare insert plate 16. The water level regulating insert plate 15 and the water level regulating spare insert plate 16 have different heights. The slot 14 is used to insert either the water level regulating insert plate 15 or the water level regulating spare insert plate 16. The height of the water level regulating spare insert plate 16 is greater than the height of the water level regulating insert plate 15.

[0040] The water level regulating plate 15 is used to ensure that the water level in the tank meets the needs of shellfish seedlings, and the water level regulating spare plate 16 is used to ensure that the water level in the tank meets the needs of other aquatic products besides shellfish seedlings.

[0041] In this specific embodiment, multiple water level regulating backup plugs 16 are provided, and the heights of the water level regulating plugs 15 and the multiple water level regulating backup plugs 16 are all different.

[0042] In this embodiment, the height of the box is above 50cm. Since the water level required for the breeding of pearl mussel seedlings is about 20cm, while the breeding of other aquatic products generally requires a water level of more than 50cm, the function of the water level adjustment spare plate 16 is designed to adjust the water level for different breeding species. This makes the multi-purpose shellfish breeding device 100 in this embodiment have multiple uses, improves the applicability of the device, and thus can give full play to the utilization value of the multi-purpose shellfish breeding device 100.

[0043] In order to guide the water discharged from the drain outlet 13, a guide plate corresponding to the position of the drain outlet 13 is provided on the outside of the box. The guide plate includes a guide bottom plate 17 and two guide side plates 18. One end of the guide bottom plate 17 and one end of the two guide side plates 18 are fixed to the outside of the box. The guide bottom plate 17 corresponds to the bottom position of the drain outlet 13, and the two guide side plates 18 correspond to the two sides of the drain outlet 13 respectively. The bottom of the two guide side plates 18 is connected to the two sides of the upper part of the guide bottom plate 17 respectively.

[0044] In order to facilitate the outflow of water from the drain outlet 13, the guide plate 17 is inclined downward from one end connected to the box to the other end away from the box.

[0045] In this embodiment, the box is a rectangular box with an open top, including a base plate 1 and two parallel first side plates 2 and two parallel second side plates 3 disposed on the base plate 1. The front and rear ends of one first side plate 2 are respectively connected to one end of the two second side plates 3, and the front and rear ends of the other first side plate 2 are respectively connected to the other end of the two second side plates 3. Each support plate 4 is disposed on the upper part of the outer side of one first side plate 2. The upper part of each of the two second side plates 3 is provided with a slot, and the strip groove in the slot extends along the length direction of the second side plate 3. The connecting groove in the slot penetrates the inner wall of the second side plate 3. The drain outlet 13 is disposed on the front second side plate 3 and penetrates the upper end of the second side plate 3. One end of the flow guide bottom plate 17 and one end of the two flow guide side plates 18 are fixed to the outside of the front second side plate 3. The pull ring 19 is disposed on the outside of the front second side plate 3. Specifically, there are two pull rings 19.

[0046] In this specific embodiment, the housing and the two support plates 4 are an integral structure and are made of plastic. The baffle plate, pressure strip 8, and positioning plate 9 are all made of plastic.

[0047] The specific usage process is as follows: Insert each baffle into a slot, insert the pressure strip 8 into the groove of each baffle, and rotate each pressure plate 12 to be above a positioning plate 9, so that its upper and lower sides can be tightly fitted with the horizontal plate 11 and the positioning plate 9 respectively, thereby limiting the two positioning plates 9 and the pressure strip 8. Insert the water level adjustment plate 15 into the two slots 14 of the drain outlet 13, lay bottom mud at the bottom of the tank, put in shellfish seedlings, turn on the faucet, and let water enter through the inlet of the meandering channel. The water flows in the meandering channel, thereby fully covering all areas in the tank, and finally flows out from the drain outlet 13 and the guide plate.

[0048] When it is time to collect the seedlings, move the pressure plate 12 so that it is no longer pressed on the positioning plate 9, remove the pressure strip 8, and then continue to remove the baffle plates. Use a large mesh net to scoop out shellfish seedlings about 1 cm long from inside the box.

[0049] This specification 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. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
