A plurality of groups of support legs are arranged on the outer wall of the cultivation chamber. A control panel is also arranged on the outer wall of the cultivation chamber.

[0008] As a further scheme of the present invention: an overflow control ring is movably installed on the inner wall of the overflow chamber. The overflow control ring is composed of a vertical part and a horizontal part. The vertical part abuts against the inner wall of the cultivation chamber. The horizontal part abuts against the inner wall of the top of the overflow table.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention can conveniently adjust the water level in the cultivation bin through the overflow control ring. When the first current-limiting port coincides with the first overflow port, the water level is at a lower level. When the second current-limiting port coincides with the second overflow port, the first overflow port at the bottom is closed and the water level is at a medium level. When the third current-limiting port coincides with the third overflow port, both the first overflow port and the second overflow port at the bottom are closed and the water level is at a higher level. Through overflow, the food residues and sundries remaining on the water surface can be removed, and the wastewater is discharged through the filter screen and the drainage bin. A small amount of accidentally discharged sea cucumber larvae slide into the tipping bucket through the return port. This design improves the stability and freedom of the sea cucumber seedling cultivation device.

[0017] 2. The present invention can clean the sediment impurities at the bottom of the cultivation bin through the design of the deposition bin. When the cleaning motor drives the scraping plate to rotate, the inner wall of the cultivation bin can be cleaned. When the scraping plate does not block the deposition port, the sediment at the bottom of the cultivation bin falls into the deposition bin. When it needs to be discharged, rotate the scraping plate to block the deposition port. At this time, the deposition bin becomes a closed bin. Then open the control valve, and the sewage is discharged through the filter screen and the drainage bin. A small amount of sea cucumber larvae also slide into the tipping bucket through the return port. This design improves the practicability of the sea cucumber seedling cultivation device.

[0018] 3. The present invention can throw the sea cucumber larvae back into the cultivation bin again through the design of the tipping bucket and the lifting seat. In the natural state, due to the center of gravity of the tipping bucket being at the rear end, the tipping bucket tilts outward. When the lifting motor drives the tipping bucket and the lifting seat to move upward to the top, start the relay and then drive the tipping bucket and the lifting seat downward. At this time, the tail end of the tipping bucket is adsorbed by the relay. When moving downward, the tipping bucket gradually tilts inward, and then the secondary sliding plate automatically opens, and the sea cucumbers flow back into the cultivation bin along the tipping bucket and the secondary sliding plate. This design reduces the breeding cost of the sea cucumber seedling cultivation device. Description of the Drawings

[0023] In this embodiment: The sea intestine seedling cultivation device with a self-cleaning structure is mainly divided into three parts: the cultivation tank 1, the overflow control ring 11 and the tipping bucket 36 structure. When the device is in use, first, water is added to the cultivation tank 1 through an external pipeline to cultivate the seedlings. When there are impurities on the water surface and the bottom of the cultivation tank 1 that need to be cleaned, water is continuously added to the cultivation tank 1 and the cleaning motor 23 is started. The impurities on the water surface enter the overflow chamber 2 by means of overflow. The waste water is discharged through the filter screen 25 and the drainage chamber 26. A small number of accidentally discharged sea intestine larvae slide into the tipping bucket 36 through the return port 28. Under the action of gravity, the sediment at the bottom of the cultivation tank 1 falls into the sedimentation chamber 20. Then the rotary scraping plate 24 is rotated and the sedimentation port 21 is blocked. Finally, the control valve 41 is opened. The sewage containing a small number of sea intestine larvae enters the overflow chamber 2 through the slag discharge pipe 40. The waste water is discharged through the filter screen 25 and the drainage chamber 26. A small number of sea intestine larvae also slide into the tipping bucket 36 through the return port 28. Then the lifting motor 31 is started to drive the tipping bucket 36 and the lifting seat 34 to move upward to the top. Then the relay 33 is turned on. When the tail end of the tipping bucket 36 is adsorbed by the relay 33, the lifting motor 31 is started again to drive the tipping bucket 36 and the lifting seat 34 to move downward. At this time, the tipping bucket 36 gradually inclines inward. Under the action of gravity, the auxiliary slide plate 39 automatically slides out of the telescopic cavity 38, and the sea intestine slides into the interior of the cultivation tank 1 through the auxiliary slide plate 39.

[0027] In this embodiment: The water level in the cultivation chamber 1 can be conveniently adjusted through the overflow control ring 11. When the first current-limiting port 14 coincides with the first overflow port 7, the water level is at a lower level. When the second current-limiting port 15 coincides with the second overflow port 8, the first overflow port 7 at the bottom is closed and the water level is at a medium level. When the third current-limiting port 16 coincides with the third overflow port 9, both the first overflow port 7 and the second overflow port 8 at the bottom are closed and the water level is at a higher level. Through overflow, the food residues and sundries remaining on the water surface can be removed.

[0028] Refer to the appendix Figure 2 - appendix Figure 4 , a plurality of rotating grooves 10 are provided on the outer wall of the cultivation chamber 1. A gear ring 17 penetrating through the rotating grooves 10 is installed on the outer wall of the horizontal part 13.

The overflow control ring 11 is installed on the cultivation chamber 1 through the rotating grooves 10. In order to drive the rotation of the overflow control ring 11, the water level motor 18 structure is designed.

[0030] Refer to the appendix Figure 2 - appendix Figure 3 , a device chamber 22 located at the bottom of the sedimentation chamber 20 is arranged inside the overflow chamber 2.

The scraping plates 24 abut against the inner wall of the cultivation chamber 1.

[0031] In this embodiment: Through the design of the sedimentation bin 20, the present invention can clean the sediment impurities at the bottom of the cultivation bin 1. When the cleaning motor 23 drives the scraping plate 24 to rotate, the inner wall of the cultivation bin 1 can be circularly scraped and cleaned. Part of the sundries scraped off float to the water surface and are discharged through overflow, and part sink to the bottom and are discharged through the sedimentation bin 20.

[0032] Refer to the attached Figure 2 and the attached Figure 5 , a filter screen 25 communicating with the overflow chamber 2 is installed at the bottom of the cultivation bin 1, a circular drainage bin 26 is installed at the bottom of the cultivation bin 1, and a drain pipe 27 is provided on the outer wall of the drainage bin 26.

[0033] In this embodiment: In order to filter the overflow wastewater and the sediment wastewater at the bottom of the cultivation bin 1 and prevent a small number of juvenile sea cucumbers from being discharged, a circular filter screen 25 structure is designed. The drain pipe 27 is communicated with an external water purification device, and the purified water body is re-introduced into the cultivation bin 1 through a pipeline.

[0034] Refer to the attached Figure 2 , a plurality of slag discharge pipes 40 communicating with the overflow chamber 2 are installed at the bottom of the sedimentation bin 20, and a control valve 41 is installed in the middle of the slag discharge pipe 40.

[0035] In this embodiment: When the scraping plate 24 does not block the sedimentation port 21, the sediment at the bottom of the cultivation bin 1 falls into the sedimentation bin 20. When it needs to be discharged, rotate the scraping plate 24 to block the sedimentation port 21. At this time, the sedimentation bin 20 becomes a closed bin body. Then open the control valve 41, and the sewage is discharged through the filter screen 25 and the drainage bin 26, and a small number of juvenile sea cucumbers also slide into the tipping bucket 36 through the return port 28.

[0036] Refer to the attached Figure 5 - the attached Figure 7 , an inclined limit baffle 35 is further provided at the bottom of the lifting seat 34.

[0037] In this embodiment: When the tipping bucket 36 is in the non-spilling stage, the tipping bucket 36 automatically deflects outward under the action of gravity. In order to limit it, the limit baffle 35 structure is designed.

[0038] Refer to the attached Figure 2 - the attached Figure 3 and the attached Figure 7 , a magnetic plate 37 is movably installed at the top of the tipping bucket 36, and a relay 33 is also installed on the support frame 30 between the lifting motors 31.

[0039] In this embodiment: In order to automatically control the discharging and resetting of the tipping bucket 36, the relay 33 structure is designed. In order to avoid jamming during discharging, the magnetic plate 37 is movably installed at the top of the tipping bucket 36.

[0040] See the appendix Figure 6 - Appendix Figure 7 At the discharge port of the tipping bucket 36, a telescopic cavity 38 is provided, and a secondary sliding plate 39 is movably installed in the telescopic cavity 38.

[0041] In this embodiment: When the tail end of the tipping bucket 36 is adsorbed by the relay 33, when the tipping bucket 36 and the lifting seat 34 move downward, the tipping bucket 36 gradually inclines inward. At this time, under the action of gravity, the secondary sliding plate 39 automatically slides out of the telescopic cavity 38, and the sea cucumbers slide into the interior of the cultivation tank 1 through the secondary sliding plate 39. When all the sea cucumbers have flowed back, the relay 33 is closed again. At this time, under the action of gravity, the tipping bucket 36 automatically falls and inclines outward, and under the action of gravity, the secondary sliding plate 39 automatically retracts into the telescopic cavity 38.

[0042] Working principle of the present invention: When the device is in use, first, water is added to the cultivation tank 1 through an external pipeline to cultivate the seedlings. When there are impurities on the water surface and at the bottom of the cultivation tank 1 that need to be cleaned, water is continuously added to the cultivation tank 1 and the cleaning motor 23 is started. The impurities on the water surface enter the overflow cavity 2 by overflow, the waste water is discharged through the filter screen 25 and the drainage chamber 26, and a small number of accidentally discharged sea cucumber larvae slide into the tipping bucket 36 through the return port 28. Under the action of gravity, the sediment at the bottom of the cultivation tank 1 falls into the sedimentation chamber 20, then the rotary scraping plate 24 is rotated to block the sedimentation port 21, and finally the control valve 41 is opened. The sewage containing a small number of sea cucumber larvae enters the overflow cavity 2 through the slag discharge pipe 40, the waste water is discharged through the filter screen 25 and the drainage chamber 26, and a small number of sea cucumber larvae also slide into the tipping bucket 36 through the return port 28. Then the lifting motor 31 is started to drive the tipping bucket 36 and the lifting seat 34 to move upward to the top, and then the relay 33 is turned on. When the tail end of the tipping bucket 36 is adsorbed by the relay 33, the lifting motor 31 is started again to drive the tipping bucket 36 and the lifting seat 34 to move downward. At this time, the tipping bucket 36 gradually inclines inward, and under the action of gravity, the secondary sliding plate 39 automatically slides out of the telescopic cavity 38, and the sea cucumbers slide into the interior of the cultivation tank 1 through the secondary sliding plate 39.
