[0022] The object of the present invention is to provide a multi-purpose shellfish seedling raising device, which avoids the problem that the local nutrient supply is insufficient, resulting in the poor development, different sizes and uneven specifications of some seedlings, has more diversified functions, and improves the utilization rate and economic benefits.

[0023] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0024] As Figure 1 - Figure 2 shown, this embodiment provides a multi-purpose shellfish seedling raising device 100, which includes a box body, a water level adjusting mechanism and a plurality of baffle plates. The upper end of the box body is an open structure. The plurality of baffle plates are sequentially arranged in a staggered manner from left to right in the box body, so as to form a meandering flow channel in the box body. The two ends of the meandering channel are respectively an inlet and an outlet. Above the inlet of the meandering channel is used to set a faucet for supplying water. A drain port 13 corresponding to the position of the outlet of the meandering flow channel is arranged on the box body. The water level adjusting mechanism is used to be arranged at the drain port 13 to realize the adjustment of the water level in the box body, so that the multi-purpose shellfish seedling raising device 100 can be used for shellfish seedling raising or the cultivation of other aquatic products.

[0025] During use, the water level in the box body is made to be a low water level through the water level adjusting mechanism to meet the use requirements of shellfish seedling raising. Bottom mud is laid in the box body, and then shellfish seedlings are put in. Water is put in from the inlet of the meandering flow channel. The water fully flows in the whole box body in the meandering flow channel and then is discharged from the drain port 13. Thus, the seedlings in each area of the box body can absorb fresh nutrients, avoiding the problem that the local nutrient supply is insufficient, resulting in the poor development, different sizes and uneven specifications of some seedlings, and enabling the production of high-quality shellfish seedlings with consistent specifications and good development.

[0026] In the non-seedling-raising season, the water level in the box body is adjusted to a high water level through the water level adjusting mechanism to meet the breeding requirements of other aquatic products. At this time, other aquatic products can be bred in the box body. Specifically, a batch of aquatic products with a short growth period can be bred, such as snails, shrimps and tropical fish. Through the water level adjusting mechanism, the shellfish seedling-raising device in this embodiment can realize shellfish seedling-raising and the breeding of other aquatic products at different times, realizing the dual use of the shellfish seedling-raising device, making its functions more diversified, avoiding the idle of the shellfish seedling-raising device, improving the utilization rate of the shellfish seedling-raising device, and improving the economic benefits.

[0027] The multi-purpose shellfish seedling-raising device 100 in this embodiment can imitate the micro-dynamic water flow conditions of the natural breeding environment of shellfish for off-season seedling-raising, and realize catching up with the traditional seedling-raising technology in the artificially imitated environment to produce high-quality mussel seedlings.

[0028] To facilitate the seedling collection work, each baffle in this embodiment is detachably installed on the box body. The detachable design of the baffle is convenient for removing the baffle after the seedlings are mature, and using a large dense net bag to salvage shellfish seedlings about 1 cm in the box body.

[0029] On the upper parts of the front and rear sides of the box body, card slots for installing the baffle are provided. The card slots on the upper part of the front side of the box body and the card slots on the upper part of the rear side of the box body are staggered. One end of each baffle is used to be clamped in a card slot.

[0030] In this specific embodiment, on the upper parts of the front and rear sides of the box body, one card slot for installing the baffle is provided, and the two card slots are staggered.

[0031] As Figure 2 shown, the card slot includes a strip-shaped slot and a communication slot perpendicular to each other arranged inside the strip-shaped slot. The communication slot penetrates the inner wall of the box body. The baffle includes a strip-shaped plate 7 and a water flow baffle 6 vertically arranged on one side of the strip-shaped plate 7. The strip-shaped plate 7 is used to be inserted into the strip-shaped slot, and one end of the water flow baffle 6 close to the strip-shaped plate 7 is used to be inserted into the communication slot. The water flow baffle 6 can be in contact with the bottom in the box body.

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

[0033] The top limiting mechanism includes a pressing strip 8 and two limiting components. At the upper parts of both ends of the pressing strip 8, a positioning plate 9 is provided respectively. At the upper parts of each water baffle 6, a groove for pressing the pressing strip 8 into is provided. The two positioning plates 9 are respectively used for being placed on the upper parts of the two supporting plates 4, and the two limiting components are respectively arranged on the upper parts of the two supporting plates 4. Each limiting component is used for limiting one positioning plate 9.

[0034] The limiting component includes a fixed block and a pressing plate 12. The fixed block and the pressing plate 12 are located on both sides of the positioning plate 9. The fixed block includes a vertical plate 10 fixed on the supporting plate 4 and a horizontal plate 11 arranged on one side of the top of the vertical plate 10. The pressing plate 12 is rotatably installed on the supporting plate 4 through a rotating shaft. The pressing plate 12 can rotate to the upper part of the positioning plate 9, and the upper and lower sides can be respectively in close contact with the horizontal plate 11 and the positioning plate 9, so as to realize the limiting of the positioning plate 9. By limiting the two positioning plates 9, the top of the pressing strip 8 is limited, so that the pressing strip 8 can be firmly pressed on the upper parts of the multiple water baffles 6.

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

[0036] An arc-shaped sliding groove 5 is arranged along the length direction of the lower part of the supporting plate 4. The arc-shaped sliding groove 5 is matched with the sliding support pipe structure on the seedling-raising support. A pull ring 19 is arranged outside the side of the box body where the drain port 13 is provided.

[0037] By arranging the arc-shaped sliding groove 5, the two supporting plates 4 can be respectively slidably installed on the two sliding support pipes of the seedling-raising support. Further, by arranging the pull ring 19 outside the box body, it is convenient to manually pull the box body to slide on the sliding support pipe, so as to facilitate the inspection management and seedling collection.

[0038] In order to facilitate the installation of the water level adjusting mechanism, the drain port 13 penetrates through the top of the box body.

[0039] The water level adjusting mechanism includes a water level adjusting insertion plate 15 and a water level adjusting spare insertion plate 16. The heights of the water level adjusting insertion plate 15 and the water level adjusting spare insertion plate 16 are different. The water level adjusting insertion plate 15 or the water level adjusting spare insertion plate 16 is used for inserting into the slots 14. The height of the water level adjusting spare insertion plate 16 is greater than the height of the water level adjusting insertion plate 15.

[0040] The water level adjusting insertion plate 15 is used for making the water level in the box body meet the requirements of shellfish seedlings, and the water level adjusting spare insertion plate 16 is used for making the water level in the box body meet the requirements of other aquatic products except shellfish seedlings.

[0041] In this specific embodiment, a plurality of water level adjustment spare plates 16 are provided, and the heights of the water level adjustment plate 15 and the plurality of water level adjustment spare plates 16 are all different from each other.

[0042] In this embodiment, the height of the box body is more than 50 cm. Since the water level required for the reproduction of pearl mussel seedlings is about 20 cm, and the cultivation of other aquatic product varieties basically requires a water level of more than 50 cm, the function of the water level adjustment spare plate 16 is designed to adjust the water level for different cultivation varieties, so that the multi-purpose shellfish breeding device 100 in this embodiment has multiple uses, improves the applicable range of the device, and further 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 outside the box body. 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 both fixed to the outside of the box body. The guide bottom plate 17 corresponds to the bottom position of the drain outlet 13, and the two guide side plates 18 respectively correspond to the two sides of the drain outlet 13. The bottoms of the two guide side plates 18 are respectively connected to the two sides of the upper part of the guide bottom plate 17.

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

[0045] The box body in this embodiment is a rectangular box body with an open upper end, including a base plate 1 and two parallel first side plates 2 and two parallel second side plates 3 arranged 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 arranged on the upper part outside one first side plate 2; clamping grooves are provided on the upper parts of the two second side plates 3, and the strip-shaped grooves in the clamping grooves extend along the length direction of the second side plates 3, and the communication grooves in the clamping grooves penetrate through the inner walls of the second side plates 3; the drain outlet 13 is arranged on the front second side plate 3 and penetrates through the upper end of the second side plate 3. One end of the guide bottom plate 17 and one end of the two guide side plates 18 are both fixed to the outside of the front second side plate 3, and a pull ring 19 is arranged on the outside of the front second side plate 3. Specifically, two pull rings 19 are provided.

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

[0047] The specific using process is as follows: insert each baffle into a card slot, clip the pressing strip 8 into the groove of each baffle, turn each pressing plate 12 to the upper side of a positioning plate 9, so that its upper and lower sides can be closely attached to the cross plate 11 and the positioning plate 9 respectively, thereby realizing the limitation of the two positioning plates 9 and the pressing strip 8. Insert the water level adjusting plug board 15 into the two slots 14 of the drain port 13, lay bottom mud at the bottom of the box body, and put in shellfish seedlings. Turn on the faucet, and water enters from the inlet of the meandering channel. The water flows in the meandering channel, thereby comprehensively covering each area in the box body, and finally flows out from the drain port 13 and the flow guiding plate.

[0048] When seedling collection is needed, turn the pressing plate 12 so that it no longer presses on the positioning plate 9, remove the pressing strip 8, and then continue to remove each baffle. Use a large dense mesh bag to fish for shellfish seedlings about 1 cm in the box body.

[0049] In this specification, specific examples are used to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
