[0039] The separation plate 30 is rotatably disposed inside the housing 10 , and the separation plate 30 is located below the partition shell 20 .

[0040] It should be noted that there is a height difference between the bottom surface of the partition shell 20 and the top surface of the separation plate 30, so that the juvenile shrimps can swim between the partition shell 20 and the separation plate 30. The specific value of the height difference is selected according to actual needs and will not be described in detail here.

[0041] The driving component 40 is disposed on the inner bottom surface of the housing 10 , and a driving shaft of the driving component 40 is connected to the separation plate 30 .

[0042] The driving component 40 may be a rotary motor.

[0043] It should be noted that the separation plate 30 can be rotatably disposed inside the housing 10 via a slide rail.

[0044] The water circulation mechanism 50 is installed on the outer wall of the shell 10 , and the water inlet of the water circulation mechanism 50 is communicated with the interior of the shell 10 , and the water inlet of the water circulation mechanism 50 is located below the separation plate 30 .

[0045] An isolation cover 51 is provided on the water inlet of the water circulation mechanism 50 to prevent young shrimps from being sucked into the water circulation mechanism 50 .

[0046] The water outlet of the water circulation mechanism 50 is in communication with the interior of the housing 10 . A water outlet pipe 52 is connected to the water outlet of the water circulation mechanism 50 . An end of the water outlet pipe 52 away from the water circulation mechanism 50 extends to an upper opening of the partition shell 20 .

[0047] It should be noted that the water circulation mechanism 50 is used to pump water under the separation plate 30 into the partition shell 20. A filtering and purification structure may also be provided inside the water circulation mechanism 50. The water circulation mechanism 50 is a prior art and will not be described in detail herein.

[0048] Further, such as Figure 2 As shown, a plurality of separation holes 31 are formed on the separation plate 30 .

[0049] It should be noted that the plurality of separation holes 31 may be 55, 56, 57, 58, 59 separation holes 31, etc. The specific number is selected according to actual needs and will not be described in detail here.

[0050] It should be noted that the juvenile shrimp can swim to the bottom of the separation plate 30 through the separation hole 31. The specific aperture of the separation hole 31 is selected according to actual needs and will not be described in detail here.

[0051] Further, such as Figure 2 As shown, a plurality of soft bristle bundles 60 are disposed on the separation plate 30 .

[0052] It should be noted that the plurality of soft hair bundles 60 may be 30, 31, 32, 33, 34 soft hair bundles 60, etc. The specific number is selected according to actual needs and will not be described in detail here.

[0053] It should be noted that the soft hair bundle 60 is composed of a plurality of soft hairs, and the soft hair bundle 60 can provide a place for the young shrimps to play and hide, thereby improving the survival rate of the young shrimps.

[0054] It should be noted that the length of the soft hair bundle 60 is selected according to actual needs and will not be described in detail here.

[0055] The power assembly is used to provide energy for the operation of the device, preferably an AC power supply or a battery; the control unit is used to control the coordinated operation of various components of the device, preferably a programmable logic controller; all of which are prior arts and will not be described in detail here.

[0056] It can be understood that the water circulation mechanism 50 is used to realize the circulation of water, and the water inlet and outlet are set to form an up and down circulating water flow. At the same time, the circulating water can promote the swimming and separation of the juvenile shrimps; the separation holes 31 on the separation plate 30 and the rotation of the driving component 40 are used to separate the juvenile shrimps from the breeding shrimps. The juvenile shrimps swim to the bottom of the separation plate 30 through the separation holes 31, while the breeding shrimps remain in the partition shell 20; the soft hair bundles 60, the partition shell 20 and other components in the device provide a good growth environment for the juvenile shrimps, which helps to improve their survival rate.

[0057] When the shrimp farming juvenile shrimp rapid separation device of the embodiment of the present application is actually operated, the steps are as follows:

[0058] S1: placing the seed shrimp on the placement table 22 of the partition shell 20, turning on the growth light assembly 12 and the oxygen supply assembly 13 to provide a suitable living environment for the young shrimp;

[0059] S2: Start the water circulation mechanism 50 to pump the water below the separation plate 30 into the partition shell 20, and spray the water into the upper opening of the partition shell 20 through the water outlet pipe 52 to form a water circulation;

[0060] S3: As the water circulates, the young shrimps swim in the separation shell 20 and swim to the bottom of the separation plate 30 through the separation holes 31 on the separation plate 30; at the same time, the driving component 40 drives the separation plate 30 to rotate slowly, further promoting the separation of the young shrimps;

[0061] S4: When the young shrimps swim to the bottom of the separation plate 30, they can be collected through the collection pipe 11, and the switch valve on the collection pipe 11 can be opened or closed as needed; in addition, the young shrimps in the housing 10 can also be caught by a fishing net.

[0062] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0063] 1. Through the water circulation and the rotation of the separation plate 30, the juvenile shrimps and the seed shrimps are quickly separated, thereby improving the separation efficiency;

[0064] 2. The soft hair bundle 60, isolation cover 51 and other components in the device effectively prevent the young shrimp from being harmed during the separation process;

[0065] 3. By providing a suitable living environment and good growth conditions, the survival rate of juvenile shrimps is improved.

[0066] Embodiment 2: In the above embodiment, if there are a large number of juvenile shrimps, the efficiency of simply relying on the juvenile shrimps to separate by swimming is too low and takes a long time; the embodiment of the present application is optimized to a certain extent on the basis of the above embodiment.

[0067] like Figure 3 As shown, a spiral plate 32 is disposed on the top surface of the separation plate 30 , and the spiral plate 32 is distributed in a spiral from the center to the edge of the separation plate 30 , and the partition shell 20 and the spiral plate 32 are staggered.

[0068] It should be noted that the bottom surface of the partition shell 20 is not lower than the top surface of the spiral plate 32 .

[0069] It should be noted that the number of turns and the pitch of the spiral plate 32 are selected according to actual needs and will not be described in detail here.

[0070] Further, such as Figure 3 As shown, the plurality of separation holes 31 on the separation plate 30 are distributed in a spiral shape along the spiral plate 32 .

[0071] Further, such as Figure 3 As shown, the plurality of soft hair bundles 60 on the separation plate 30 are distributed in a spiral shape along the spiral plate 32 .

[0072] It should be noted that the spiral plate 32 , the separation hole 31 and the soft hair bundle 60 are staggered.

[0073] It should be noted that in this embodiment, the rotation direction of the separation plate 30 is the same as the spiral direction of the spiral plate 32 from outside to inside (both are clockwise or counterclockwise).

[0074] It can be understood that when the water circulation mechanism 50 is working, the water flows through the spiral plate 32 to form a spiral flow. This flow mode not only increases the disturbance of the water flow, but also helps to guide the juvenile shrimp out of the partition shell 20; the rotation of the spiral plate 32 and the spiral flow of the water make it easier for the juvenile shrimp to be guided to the outside of the partition shell 20 during the swimming process, and the separation holes 31 on the separation plate 30 are also distributed along the spiral plate 32, further promoting the separation and swimming of the juvenile shrimp; the spiral distribution of the soft hair bundles 60 provides more places for the juvenile shrimp to play and hide, which helps to improve their survival rate and growth rate; the staggered setting between the spiral plate 32, the separation holes 31 and the soft hair bundles 60 avoids mutual interference and collision, and protects the safety of the juvenile shrimp.

[0075] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0076] 1. The arrangement of the spiral plate 32 and the formation of the spiral flow make it easier for the juvenile shrimp to separate from the separation shell 20 and swim to the bottom of the separation plate 30 or to the liquid surface, thereby improving the separation efficiency;

[0077] 2. The spiral distribution of the soft hair bundle 60 provides more ecological niches and hiding places for the juvenile shrimp, which helps to build a richer ecological environment and improve the survival rate and growth rate of the juvenile shrimp;

[0078] 3. The number of turns and pitch of the spiral plate 32, the number of separation holes 31 and the number of soft hair bundles 60 can be adjusted according to actual needs, so that the device can adapt to the needs of shrimp farming of different scales and conditions.

[0079] Embodiment 3: In the above embodiment, the soft hair bundle 60 may be bent after long-term use, which is not conducive to the hiding activities of the juvenile shrimp and affects the activity of the juvenile shrimp. The embodiment of the present application is optimized based on the above embodiment.

[0080] like Figure 1 , Figure 4 and Figure 5 As shown, the shrimp farming juvenile shrimp rapid separation device of the embodiment of the present application further includes an electromagnet assembly 80 and a plurality of bottom blocks 70 , and the number of the bottom blocks 70 is the same as the number of the soft hair bundles 60 and they correspond one to one.

[0081] The separation plate 30 is provided with a plurality of soft hair holes 33 , and the number of the soft hair holes 33 is the same as the number of the soft hair bundles 60 and they correspond one to one.

[0082] The soft bristle bundle 60 slides through the soft bristle hole 33 , and the bottom end of the soft bristle bundle 60 is disposed on the bottom block 70 .

[0083] The bottom block 70 is located below the separation plate 30 , and a tension spring 71 is disposed between the bottom block 70 and the separation plate 30 .

[0084] The material of the bottom block 70 is ferromagnetic metal.

[0085] The bottom block 70 is made of metal iron.

[0086] It should be noted that the soft bristle bundle 60 passes through the tension spring 71 .

[0087] like Figure 1 As shown, the electromagnet assembly 80 is disposed on the inner bottom surface of the housing 10 , and the electromagnet assembly 80 is located below the gap between the outer wall of the partition shell 20 and the inner wall of the housing 10 .

[0088] It can be understood that when the driving component 40 drives the separation plate 30 to rotate and the electromagnet assembly 80 is energized, the bottom block 70 moves with the separation plate 30, and the electromagnet assembly 80 generates a magnetic attraction to the bottom block 70 moved above it, so that the bottom block 70 drives the soft hair bundle 60 to move downward; by controlling the current size and direction of the electromagnet assembly 80, the strength and direction of the magnetic force can be adjusted, thereby achieving precise control of the lifting and lowering of the soft hair bundle 60; when the bottom block 70 leaves the magnetic force range of the electromagnet assembly 80, the bottom block 70 automatically resets and rises under the pulling force of the tension spring 71, driving the soft hair bundle 60 back to its original position to ensure that the soft hair bundle 60 can maintain a stable posture when not affected by external forces.

[0089] By periodically raising and lowering the soft hair bundle 60, the juvenile shrimps near the soft hair bundle 60 can be driven away, so that the juvenile shrimps can more easily break away from the partition shell 20 and swim to the bottom of the separation plate 30 or to the liquid surface, while making room for the juvenile shrimps behind; during the process of raising and lowering the soft hair bundle 60, the soft hair bundle 60 can be smoothed and some dirt on the soft hair bundle 60 can be removed.

[0090] It should be noted that the magnetic force of the electromagnet assembly 80 is controlled according to actual needs and will not be described in detail here.

[0091] It should be noted that when the bottom block 70 drives the soft hair bundle 60 to move downward, the maximum downward movement height is less than the length of the soft hair bundle 60, so that the soft hair bundle 60 will not escape from the soft hair hole 33.

[0092] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0093] 1. By adjusting the height of the soft hair bundle 60, a more suitable habitat can be provided for the young shrimps, thereby increasing their activity. At the same time, the soft hair bundle 60 also provides a place for more young shrimps to hide and rest, thereby helping to increase their survival rate and growth rate.

[0094] 2. By periodically raising and lowering the soft hair bundle 60, the young shrimps near the soft hair bundle 60 can be driven away to make room for the young shrimps behind, and at the same time, the young shrimps can more easily escape from the separation shell 20 and swim to the bottom of the separation plate 30 or the liquid surface, thereby improving the separation efficiency;

[0095] 3. The soft hair bundle 60 can be straightened during the lifting process and can also play a certain cleaning role.

[0096] Embodiment 4: In the above embodiment, if there is a lot of dirt on the soft hair bundle 60, it is not possible to effectively remove the dirt by just lifting and lowering. The embodiment of the present application is optimized to a certain extent on the basis of the above embodiment.

[0097] like Figure 6 and Figure 7As shown, an annular sleeve 90 is further provided between the bottom block 70 and the separation plate 30 , and the tension spring 71 is located in the annular sleeve 90 .

[0098] The annular sleeve 90 is a tubular structure. The top end of the annular sleeve 90 is sealedly connected to the separation plate 30 , and the bottom end of the annular sleeve 90 is sealedly connected to the bottom block 70 .

[0099] The material of the annular sleeve 90 can be rubber.

[0100] The height of the annular sleeve 90 is not greater than the length of the soft bristle bundle 60 , so that the soft bristle bundle 60 will not escape from the soft bristle hole 33 .

[0101] It should be noted that the height direction of the annular sleeve 90 is the same as the length direction of the soft hair bundle 60 .

[0102] A one-way valve 72 is disposed in the bottom block 70 , and water under the bottom block 70 can flow into the annular sleeve 90 through the one-way valve 72 .

[0103] It can be understood that, during the descent of the bottom block 70, the water below will enter the annular sleeve 90 through the one-way valve 72, and during the ascending of the bottom block 70, part of the water in the annular sleeve 90 will be sprayed out through the soft hair holes 33, which can better drive away the young shrimps and increase their activity, so that the young shrimps can more easily break away from the partition shell 20 and swim to the bottom of the separation plate 30 or to the liquid surface; in addition, the sprayed water flow can wash off some of the dirt on the soft hair bundle 60, thereby playing a certain cleaning role.

[0104] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0105] 1. The annular sleeve 90 effectively prolongs the service life of the tension spring 71 and the soft hair bundle 60, reduces the replacement cost, and at the same time makes the tension spring 71 better fixed and protected, and enhances the stability and reliability of the device;

[0106] 2. By adjusting the electromagnet assembly 80 and the one-way valve 72, the height of the soft hair bundle 60 can be more accurately controlled to provide more suitable habitat and growth conditions for the young shrimp;

[0107] 3. The water flow sprayed during the lifting and lowering of the bottom block 70 can better drive away the young shrimps and increase their activity, so that the young shrimps can more easily break away from the partition shell 20 and swim to the bottom of the separation plate 30 or to the liquid surface;

[0108] 4. The water flow sprayed out during the lifting and lowering process of the bottom block 70 can clean the soft hair bundles 60 to a certain extent, providing more suitable habitat and growth conditions for the young shrimps.

[0109] In summary, the present application achieves the technical effect of being able to effectively separate juvenile shrimps from breeding shrimps, reducing separation time, and improving the survival rate of juvenile shrimps.

[0110] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have 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.
