After the culture container is taken out, the fishing of this batch of shrimp is completed, effectively. It saves the labor during fishing, and does not need to separate immature shrimp and wild fish; at the same time, the breeding density can be increased in a standardized manner, and it is convenient to culture shrimps at different growth stages in different culture containers 4 in the same pool, thereby Orderly and controllable management of shrimp aquaculture and fishing is possible. The bottom of the culture pond 1 is installed with a first through pipe 51 connected to the top of the first purification tank 2, and the end of the first through pipe 51 has a first pump (the first pump and the following The second pump and the third pump (not shown in the drawings) are used to pump the water in the culture pond 1 to the first purification pond 2 .

The structure of the first purification pond 2 and the culturing pond 1 are similar to the open cuboid structure made of concrete, wherein the attachment plate 21 is installed, and the attachment plate 21 is a plate-shaped part with a certain size of holes made of plastic or nylon mesh, which can be The snails provide a surface for attachment and survival, and can filter the water flow injected by the first pump from the first purification tank 2 through the holes on the surface. The attachment plate 21 includes a plurality of vertical and parallel spaced apart, so as to increase the contact area of the snail with the water in the first purification tank after attachment, its width is equal to the width of the first purification tank 2, and the attachment plate 21 faces the first channel. The water inlet direction of the pipe 51 is convenient to contact and filter the water flow from the first through pipe 51 . In the first purification tank 2, a slot 23 is poured through concrete, and the thickness of the attachment plate 21 is less than or equal to the opening width of the slot 23, so that it can be movably inserted into the slot 23, so as to facilitate the fishing and harvesting of snails , It is also easy to take out and clean after long-term cultivation. The bottom of the first purification tank 2 is connected with a second through pipe 52 that communicates with the top of the second purification tank 3 . The end of the second through-pipe 52 is provided with a second pump whose pumping direction is directed to the second purification tank 3 for pumping the water in the first purification tank 2 to the second purification tank 3 .

The external structure of the second purification tank 3 is the same as that of the breeding tank 1 and the second purification tank 2, and its internal cavity includes a panel/wall partition made of poured concrete or other materials that do not corrode and can provide a certain water blocking function. A first cavity 32 , a second cavity 33 and a third cavity 34 are formed in sequence from the end of the second through-pipe 52 to the end of the third through-pipe 53 . To the inlet 321 of the second cavity 33, the second purification tank 3 is provided with an ecological floating bed 31, the ecological floating bed 31 is located in the second cavity 33, and an overflow port 331 is provided between the second cavity 33 and the third cavity 34 . It has a third through pipe 53 connected to the culture tank 1 on the opposite side of the access side of the second through pipe 52 , and the end of the third through pipe 53 has a third pump whose pumping direction points to the culture tank 1 .

The end of the third through-pipe 53 is connected with a branch pipe 531 having a corresponding number of culture containers 4 through the branch row, and the end of each branch pipe 531 is connected to the upper end of the corresponding culture container 4 .

When culturing, firstly inject sufficient water into the culturing pond 1, the first purification pond 2 and the second purification pond 3. Thereafter, shrimp fry can be put into the culture container 4 that has been cleaned and sterilized outside, and the culture container 4 can be placed on the support frame 11 for fixation. At this time, the cultivation of shrimp can start. The feed is put in, and the water supply in each aquaculture container 4 is supplied with flowing water by the third pump through the branch pipe 531 to achieve a suitable environment for shrimp growth. The water supply of the branch pipe 531 is also conducive to the entry of oxygen-rich water into the culture container 4 for supply. oxygen. At the same time, the water supply from the top of the branch pipe 531 makes the water flow downward along the culture container 4 to the bottom of the culture tank 1 under the action of inertia, which simultaneously drives the feed downward for the shrimp in the whole culture container 4 to eat, and also eats the leftovers. The feed residue and shrimp excrement are brought to the bottom of the culture tank 1, and the first pump can be started at this time, and the water mixed with the feed residue and shrimp excrement is pumped into the first purification tank 2 through the first pipe 51. Previously, the attachment plate 21 can be placed in the first purification tank 2 in advance and the larvae of the snails are put in. After the water mixed with the feed residue enters the first purification tank 2, it changes from the first pump to the second pump under the action of the first pump and the second pump. The flow from the access point of the first through-pipe 51 to the connection of the second through-pipe 52, at this time, the water flow passes through each attachment plate 21, and the snails clinging to the inner surface of the second purification tank 2 and the attachment plate 21 can be easily Feed residue mixed in the eating water, and the holes on the attachment plate 21 can filter the water flow to intercept some larger feed particles, further reduce the residual feed in the water entering the second purification tank 3, and also facilitate the snails to eat. . In the first purification tank 2, that is, by the snails, most of the feed in the water exiting from the culture tank 1 is eliminated, and the snails can be effectively cultured to provide additional economic benefits. The water coming to the second purification tank 3 is mainly mixed with the excrement of shrimps and snails, and is accompanied by a small amount of feed residues. Because the upper part of the first cavity 32 is closed, it flows downward in the first cavity 32, and in the first cavity 32 flows downward. 32 The lower water flow enters the second cavity 33 through the inlet 321, and the feces and feed residues of shrimp and snails are basically deposited here under the action of gravity, that is, the relatively clean water flows upward to the second cavity 33. In the ecological floating bed 31 , farmers can put certain nitrifying bacteria strains in the first cavity 32 and the second cavity 33 , through which the ammonia gas generated in the feces and feed residues of shrimp and snails can be decomposed to the ecological floating bed 31 . Nitrates absorbed by the plants on the plant, thereby further improving the level of purification and reducing the toxicity of ammonia produced by manure and feed residues to shrimp. The ecological floating bed 31 can be planted with water hyacinth and other aquatic plants with strong impurity adsorption function in water, so that the water can be purified to the greatest extent when returning from the second purification tank 3 to the culture tank 1 . The ecological floating bed 31 floats on the top of the second chamber 33 , and the water purified by them flows into the third chamber 34 from the overflow port 331 (this structure also makes the water must pass through the ecological floating bed 31 to flow out), and at the third chamber 34 Under the action of the third pump, it flows into the culture tank 1 through the third passage pipe 52 and enters the culture container 4 again to perform the above-mentioned circulation.

In this embodiment, the breeding container 4 includes a rectangular outer shell 41 (the outer shell 41 can be a closed or only rectangular frame, as long as it can be placed on the support frame 11 and support the inner inner shell 42 ) and a connecting rod A circular vertical stainless steel or polymer plastic inner casing 42 connected in the outer casing 41, the end of the branch pipe 531 is fixed on the top of the inner casing 42 through a snap ring, etc. and points to its wall surface, the axis of the branch pipe 531 and the circumference of the inner casing 42 Tangent. The inner wall of the inner shell 42 is integrally formed or welded with a guide plate 43 (the guide plate 43 can be continuous as in this embodiment, or it can be a segmented and spaced structure) arranged along the spiral line located on the inner wall. The rotation direction of 43 corresponds to the opening direction of the branch pipe 531 . After the water flow from the branch pipe 531 hits the inner wall of the inner shell 42 with a tangential line, it rushes downward spirally under the guidance of its surface. The guide plate 43 can maintain and guide this water flow structure to the lower end of the inner shell 42. The flow structure is conducive to the agitation of water in the culture container 4, the mixing of oxygen in the air, the uniform distribution of the feed in the culture container 4, and at the same time, it will not directly impact the shrimp in the inner shell 42, so as to avoid damage to the middle of the inner shell 42. shrimp

In this embodiment, the bottom of the culture container 4 is covered with a perforated plate 44 having through holes with a diameter of 0.5-1.5 cm. On the one hand, the perforated plate 44 can allow the flow of water mixed with feed residues to pass through, and on the other hand, its aperture can prevent shrimp To escape outward, its aperture can be selected according to the species and growth stage of the shrimp cultured in the culture container 4 . The perforated plate 44 is detachably installed on the bottom of the culture container 4 through screws or snaps, so that the perforated plate 44 can be conveniently opened for collection after the shrimp is matured and fished out.

In this embodiment, the first purification tank 2 is covered with a cut-off net 22 where the first pass pipe 51 and the second pass pipe 52 are connected. Escape, to avoid excessively multiplying snails adhering to the inside of the pipe to cause blockage or damage to the first pump and the second pump.

In this embodiment, an oxygen supply pipe 341 and a liquid supply pipe 342 are laid at the bottom of the third cavity 34 , so that the water in the third cavity 34 and waiting to enter the culture tank 1 can be provided with additional oxygen and liquid supply devices through external oxygen supply devices and liquid supply devices. The dissolved oxygen and trace elements dissolved in the liquid, shrimp medicines, disinfectants, etc. The moisture after the components are adjusted through the oxygen supply 341 and the liquid supply pipe 342 can directly enter the culture container 4 through the third passage 53 to achieve targeted oxygen supply, treatment, disinfection and the like.

In this embodiment, a filter screen 35 with a plurality of accommodating holes 351 is placed horizontally in the second cavity 33 under the overflow port 331 by means of snaps. The ecological floating bed 31 is located below the accommodating holes 351, and its horizontal area is larger than that of the accommodating holes. The opening area of 351, so as to float upward and be suspended in the water by the limit of the accommodating hole 351, which can effectively locate the position of the ecological floating bed 31, ensure its effect of purifying water quality, and prevent it from falling when the water level is high. inside the third cavity 34 . Part of the shrimp, snail feces and feed residues entrained by the water flow can be filtered at the filter screen 35 to prevent them from entering the third cavity 34 and returning to the culture tank 1 to affect the water quality of the culture. The side of the second cavity 33 is provided with an openable and closable cleaning door 36 whose vertical position is lower than the filter screen 35. After long-term cultivation, there must be a lot of feces, feed residues and residual substances after bacterial decomposition. The cleaning door 36 can conveniently open the connection between the first cavity 32 and the second cavity 33 and remove these residual substances, so as to avoid blocking the water flow path and polluting the water quality.
