[0087] As a preferred embodiment of the present invention, the support and rotation member includes:

[0088] A fixed plate 12 is symmetrically fixed on the culture tank 1;

[0089] A support ring 13 is inserted through the fixing plate 12 and fixed thereto;

[0090] The frame ring 14 is fixed to the end of the fixed plate 12 away from the cultivation tank 1;

[0091] The frame plate 15 is symmetrically fixed on the inner side of the frame ring 14;

[0092] The speed reducer 16 is fixed to one end of the frame plate 15 away from the frame ring 14 .

[0093] Specifically, the fixing plate 12 can provide stable support for the support ring 13 and the frame ring 14 under the support of the cultivation tank 1 , and the frame ring 14 can stably support the frame plate 15 , so that the frame plate 15 stably supports the reducer 16 .

[0094] The rotary push piece includes:

[0095] The motor 17 is fixed to the input end of the reducer 16;

[0096] The support plate 20 is arranged at the output end of the reducer 16, and the support frame 19 is symmetrically fixed on the support plate 20;

[0097] There are two L rods 21, and the two L rods 21 are evenly arranged on the outer side of the supporting plate 20;

[0098] The triangular inclined plate 22 is fixed to one end of the L rod 21 close to the cultivation tank 1 .

[0099] Specifically, the reducer 16 can provide support for the motor 17 under the support of the frame plate 15. After the motor 17 is started, the reducer 16 can be started to run, so that the reducer 16 slows down the rotation speed transmitted by the motor 17 and drives the equipment connected to its output end to rotate. The support plate 20 can drive the L rod 21 to rotate together under the drive of the reducer 16, so that the L rod 21 can drive the triangular inclined plate 22 to rotate. The triangular inclined plate 22 can fit with the inner side of the bottom wall of the cultivation pool 1 and has an inclination angle toward the ecological collector 9.

[0100] In actual application of this embodiment, the staff can start the motor 17 under the support of the fixed plate 12, the support ring 13, the frame ring 14 and the frame plate 15 according to the actual needs, so that the motor 17 drives the reducer 16 to operate, and the reducer 16 drives the electric rod 18 to rotate clockwise, and the electric rod 18 will drive the support plate 20 to rotate through the support frame 19, so that the support plate 20 uses the rotational power to drive the L rod 21 to rotate clockwise together, and the triangular inclined plate 22 rotates clockwise with the L rod 21 and uses the rotational power and the inclination angle to push the Murray cod feces, residual feed and impurities deposited at the bottom of the cultivation pool 1 to approach the ecological trap 9, so that the ecological trap 9 can better discharge feces, residual feed and impurities.

[0101] When the triangular inclined plate 22 is driven by the L rod 21 to rotate at a low speed, the water in the cultivation pool 1 will be slowly disturbed during the rotation process, so that the water and the triangular inclined plate 22 cooperate to push the Murray cod cultivated in the water, so that the Murray cod can be promoted to swim in the water, slightly increasing the amount of exercise of the Murray cod, making the Murray cod healthier and improving the firmness of the meat.

[0102] In another preferred embodiment of the present invention, the cultivation member comprises:

[0103] A guide rod 24, which penetrates the support ring 13 for guiding;

[0104] The egg bed 25 is fixed to the end of the guide rod 24 away from the support ring 13 and keeps a distance from the culture tank 1;

[0105] The egg mattress 26 is arranged on the egg bed 25 .

[0106] Specifically, a plurality of guide holes 23 are formed through the interior of the support ring 13, and the guide holes 23 are located on the outside of the guide rod 24. The guide holes 23 can provide a through channel for the guide rod 24. The guide holes 23 cooperate with the support ring 13 to provide a guiding function for the guide rod 24 to move up and down. The distance between the egg bed 25 and the breeding pool 1 can provide an air-permeable and water-permeable space for the egg bed 25 and the egg mattress 26. The egg bed 25 can provide a stable support for the egg mattress 26. The egg mattress 26 can provide a spawning position for the Murray cod. The egg mattress 26 is made of dry palm leaves, which is convenient for fixing the fish eggs produced by the Murray cod.

[0108] The hollow rod 27 is fixed on the outside of the egg bed 25 and is symmetrical to the guide rod 24 and extends outside the culture tank 1;

[0109] The funnel 29 is fixed to the end of the hollow rod 27 away from the cultivation tank 1;

[0110] A through slot 30 is formed through the hollow rod 27;

[0111] The guide tube 31 is disposed on a side of the hollow rod 27 facing the guide rod 24 and is communicated with the through groove 30 .

[0112] Specifically, the egg bed 25 can provide support for the hollow rod 27, the hollow rod 27 can provide a space for the through groove 30, the funnel 29, the through groove 30 and the conduit 31 can provide a circulation channel for the male semen of Murray cod, so that the semen can be discharged onto the egg bed 26, and the interior of the frame 15 is symmetrically penetrated with through holes 33, and the through holes 33 are located on the outside of the pull rope 50 and the rope 34.

[0113] In the actual application process of this embodiment, the staff can control the electric rod 18 to extend to the limit according to the actual situation after the motor 17 is started, so that the electric rod 18 uses the telescopic end to push the pressure ring 37 downward, so that the pressure ring 37 contacts the arc push plate 40 during the downward movement, and continues to push the arc push plate 40, so that the arc push plate 40 uses its own inclination angle to drive the rubber block 42 along the T-slot 38 to move toward the direction close to the winding ring 36 under the pressure of the pressure ring 37, so that the rubber block 42 fits with the inner side of the winding ring 36, thereby positioning the winding ring 36, so that after the motor 17 is started, the reducer 16, the electric rod 18, the support frame 19, the support plate 20, the first bearing 35 and the rubber block 42 can be passed. The winding drum is driven to rotate, so that the winding drum reels up the rope 34, and the rope 34 uses the reeling external force to move through the through hole 33 toward the winding drum under the support of the frame ring 14 and the frame plate 15, so that the winding drum reels up the rope 34, and then the rope 34 pulls the guide rod 24 upward, so that the guide rod 24 passes through the guide hole 23 and pulls the egg bed 25 upward under the guidance of the support ring 13, so that the egg bed 25 drives the egg mattress 26 to move upward together and move it out of the water in the breeding pond 1, so as to facilitate the staff to operate and replace the egg mattress 26. After the egg bed 25 and the egg mattress 26 are placed in the breeding pond 1, the Murray cod in the breeding pond 1 can lay fish eggs on the egg bed 25 and the egg mattress 26 for hatching during the spawning period.

[0114] After placing the egg bed 25 and the egg mattress 26 into the water in the cultivation pool 1, the staff can inject Murray cod semen into the inner side of the funnel 29, so that the semen passes through the funnel 29 into the through groove 30, falls along the through groove 30 and flows out to the inner side of the catheter 31, and then the semen passes through the guide rod 24 under the action of gravity and is discharged onto the egg mattress 26, so that the semen can match the fish eggs on the egg mattress 26 to fertilize the fish eggs, thereby facilitating artificial insemination and cultivation of Murray cod eggs.

[0115] As a preferred embodiment of the present invention, the capture element comprises:

[0116] A bellows 48, one end of which is fixedly mounted on the outer side of the egg bed 25;

[0121] Specifically, the egg bed 25 can provide support for one end of the corrugated cylinder 48 under the support of the guide rod 24. The corrugated cylinder 48 can be unfolded under the action of external force, and will rebound and fold and shrink after the external force disappears. The guide groove 45 can provide a through channel and lifting space for the connecting ring 46. The connecting ring 46 can firmly support the connecting plate 47, so that the connecting plate 47 can firmly support the other end of the corrugated cylinder 48 to push the other end of the corrugated cylinder 48 to move.

[0122] The pull-out parts include:

[0123] The electric rod 18 is connected to the output end of the reducer 16, and the outer side of the fixed end of the electric rod 18 is fixedly connected to the end of the support frame 19 away from the support plate 20;

[0136] The winding ring 36 is sleeved on the outer side of the first bearing 35 and is located above the L rod 21. The other end of the winding rope 34 is connected to the outer side of the winding ring 36.

[0137] Positioning guide parts are arranged on the winding ring 36 , the guide rod 24 and the supporting plate 20 .

[0138] Specifically, the rope 34 and the pull rope 50 can be deformed under the action of external force, the support frame 19 can provide support for the first bearing 35, the first bearing 35 can provide rotational support for the winding ring 36, and the winding ring 36 can provide winding space and support for the rope 34.

[0139] Positioning guide parts:

[0140] The positioning ring 44 is symmetrically arranged above the winding ring 36 through the connecting member and is located outside the winding rope 34;

[0141] The through opening 32 is opened through the interior of the guide rod 24 and is located above the guide groove 45 and outside the rope 34;

[0142] T-slots 38 are symmetrically provided on the support plate 20;

[0143] The arc push plate 40 is symmetrically arranged on the support plate 20 and is connected to the T-slot 38 for movement and guidance, and is located inside the winding ring 36 and below the pressure ring 37;

[0144] The rubber block 42 is fixed to a side of the arc push plate 40 close to the winding ring 36 through a connecting component.

[0145] Specifically, the T guide plate 39 is slidably arranged on the inner side of the T groove 38, and the T guide plate 39 is fixedly connected to the arc push plate 40, a connecting plate 41 is fixedly arranged on the side of the arc push plate 40 close to the winding ring 36, and the connecting plate 41 is fixedly connected to the rubber block 42, and an arc support rod 43 is symmetrically fixed on the winding ring 36, and one end of the arc support rod 43 away from the winding ring 36 is fixedly connected to the positioning ring 44.

[0146] The T-slot 38 can provide a moving guide for the T-guide plate 39 under the support of the support plate 20, and the T-guide plate 39 can provide support for the arc push plate 40. The arc push plate 40 can firmly support the rubber block 42 through the connecting plate 41, and can push the rubber block 42 to move through the connecting plate 41 under the action of external force. The rubber block 42 is made of rubber material, can be deformed under the action of external force, and will rebound when the external force disappears, and is relatively rough.

[0147] In the actual application of this embodiment, the staff needs to place the egg mattress 26 on the egg bed 25, and then the staff can control the electric rod 18 to contract according to the actual needs, so that the electric rod 18 drives the pressure ring 37 to separate from the arc push plate 40, thereby releasing the squeezing of the arc push plate 40, the rubber block 42 and the winding ring 36, so that the egg bed 25 and the egg mattress 26 move downward along the guide hole 23 through the guide rod 24 under the action of gravity under the guidance of the support ring 13, so that the guide rod 24 pulls the winding rope 34 during the downward movement. The rope 34 wound on the outside of the winding ring 36 is supported by the support ring 13 and the frame plate 15, and the winding ring 36 is pulled to rotate under the support of the first bearing 35 and the support frame 19, so that the rope 34 wound on the outside of the winding ring 36 can be released, and then the egg bed 25 and the egg mattress 26 can be moved downward and placed in the cultivation pool 1. Then, the support ring 13 will provide a resistance for the top of the guide rod 24 under the support of the fixed plate 12, so that the support ring 13 provides support for the egg bed 25 through the guide rod 24, so that the egg bed 25 maintains a distance from the bottom of the cultivation pool 1.

[0148] The connecting ring 46 is made of a magnet and has a certain magnetic property, while the hollow rod 27 and the guide rod 24 are made of stainless steel and can be attracted by the magnet.

[0149] The staff can put the bait into the inner side of the funnel 29 according to the actual needs, so that the bait passes through the through groove 30 and the conduit 31 under the action of gravity and is discharged into the water above the egg mattress 26. When the Murray cod in the breeding pool 1 is lured to the top of the egg mattress 26 by the bait, the staff needs to control the electric rod 18 to slowly extend in time. When the electric rod 18 is extended to one-third, the telescopic end of the electric rod 18 will push the pressure ring 37 downward, so that the pressure ring 37 drives the second bearing 51 to move downward along the outer side of the electric rod 18 through the fixed rod 52 during the downward movement. At the same time, the second bearing 51 will pull the pull rope 50 during the downward movement, so that the pull rope 50 pulls the N frame 49 under the action of external force and the support of the frame plate 15 and the frame ring 14, so that the N frame 49 pulls the connecting plate 47 under the action of external force, so that the connecting plate 47 drives the connecting ring 46 to move upward along the guide groove 45 and the guide groove 28, so that the guide groove 45 and the guide groove 28 provide movement for the connecting ring 46 The connecting ring 46 is guided so that the end of the bellows 48 away from the egg bed 25 moves upward through the connecting plate 47 under the action of external force, so that the bellows 48 is pulled upward and slowly unfolded under the support of the egg bed 25, so that the bellows 48 surrounds the Murray cod above the egg bed 26, and at the same time, the connecting ring 46 uses its own magnetic force to adsorb on the guide rod 24 and the hollow rod 27, and then continues to control the electric rod 18 to extend to the limit, and then promotes the rubber block 42 under the push of the electric rod 18. The winding ring 36 is squeezed to rotate together with the support frame 19 and the support plate 20, so that the winding ring 36 reels in the rope 34, and the rope 34 pulls the egg bed 25, the egg bed 26, the corrugated cylinder 48, the water inside the corrugated cylinder 48 and the Murray cod to move upward, so that the Murray cod can move closer to the edge of the breeding pond 1, which is convenient for the staff to observe the appearance of the Murray cod, so as to judge the health of the Murray cod, and moving with the water can prevent the Murray cod from being harmed.

[0150] Working principle: The thermostat 3 delivers water to the cultivation pool 1 through the water supply pipe 4, and after heating, the water is input into the cultivation pool 1 through the water pipe 5. The water temperature in the cultivation pool 1 is monitored in real time by the water temperature detector 53 and fed back to the thermostat 3 to ensure that the water temperature is always within the range suitable for the growth of Murray cod. The thermostat 3 achieves the stability of the water environment in the cultivation pool 1 by controlling the inlet water temperature and flow rate. After the water flows from the cultivation pool 1 through the ecological trap 9, it is discharged through the discharge pipe 10, and then flows back into the cultivation pool 1 after external treatment.

[0151] The water in the eco-trap 9 is discharged through the discharge pipe 10, and the discharge pipe 10 is equipped with a flange 11, which is convenient for connecting to an external drainage pipe for sewage treatment and realizing the recycling of water resources. The opening and closing of the eco-trap 9 is controlled by the staff, and the waste is discharged into the external treatment system as needed.

[0152] The rotary push member includes a motor 17, a reducer 16, a support plate 20 and an L rod 21. The rotating action can drive the triangular inclined plate 22 to rotate. The triangular inclined plate 22 pushes the sediment to move toward the collector by fitting with the bottom wall of the pool. This design effectively ensures the cleanliness of the pool bottom and reduces the accumulation of harmful substances. Waste in sewage is effectively collected and discharged, which not only reduces the waste of water resources but also reduces environmental pollution. The purified water is reintroduced into the cultivation pool 1, which greatly improves the utilization efficiency of water resources and keeps the water clean. In particular, the fitting design of the triangular inclined plate 22 and the bottom wall of the pool can easily push the sediment to the ecological collector 9, reducing the burden of manual cleaning, and effectively preventing the excessive accumulation of sediment in the cultivation pool 1, ensuring a healthy growth environment for Murray cod.

[0153] Artificial breeding of Murray cod is carried out through the egg-raising part, and the egg mattress 26 is used for spawning and hatching Murray cod eggs. The sperm injection part provides a semen injection channel through the hollow rod 27 and the funnel 29, ensuring that the semen reaches the fish eggs on the egg mattress 26 evenly and accurately to complete the artificial insemination process. The egg mattress 26 is made of dry palm leaves, has good air permeability and water permeability, and provides an ideal environment for the hatching of Murray cod eggs.

[0154] The lifting member cooperates with the connecting ring 46 to control the expansion and contraction of the bellows 48 through the electric rod 18. The bellows 48 can surround the fish eggs and Murray cod on the egg mattress 26, and its position can be adjusted by the lifting member as needed, so that the staff can observe the health of the fish body.

[0155] The design of the pusher and water disturbance not only helps to clean the water, but also promotes the movement of Murray cod through slight water disturbance, thereby increasing its exercise volume and health status and enhancing the firmness of the meat.

[0156] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
