[0037] The two ends of the inner bottom wall of the seedling raising box 1 gradually decrease toward the middle end, and a connecting hole 3 is opened at the middle end. The middle and lower ends of the inner wall of the seedling raising box 1 are provided with a filter screen 9 for filtering residual bait and feces and a cleaning component 13 for cleaning the filter screen 9 and the inner bottom wall of the seedling raising box 1 in sequence from top to bottom.

[0038] The seedling raising box 1 and the filter box 2 are connected via a connecting member 6 .

[0039] In this scheme, a connecting pipe 4 is connected to the connecting hole 3, one end of the connecting pipe 4 is connected to the connecting hole 3, and the other end is connected to the connecting component 6, and an electromagnetic valve 5 is installed on the connecting pipe 4; a support block 8 is provided on the inner wall of the seedling box 1, and a filter plate 9 is installed on the support block 8, and the filter holes of the filter plate 9 are larger than the residual bait and feces, and smaller than the aquatic product seedlings. The residual bait and feces fall to the bottom of the seedling box 1 through the filter holes of the filter plate 9.

[0040] When it is necessary to clean the residual bait, feces and other dirt in the seedling box 1, open the solenoid valve 5, and the residual bait and feces mixed water settled at the bottom of the seedling box 1 enters the filter box 2 from the connecting hole 3 through the connecting pipe 4 and the connecting member 6. At the same time, when the water in the seedling box 1 is extracted, the residual bait and feces attached to the bottom of the inner wall of the seedling box 1 and blocked in the filter holes of the filter mesh plate 9 can be cleaned through the cleaning component 13, so that the cleaned residual bait and feces enter the filter box 2 together with the connecting component, and the impurity removal mechanism 7 filters and removes the residual bait and feces in the water, and then the filtered water is injected into the seedling box 1 again through the connecting member 6, so as to achieve the replacement and recycling of the water body.

[0041] Among them, the seedling box 1, the connecting component 6, and the filter box 2 form a connected space. The residual bait and feces attached to the bottom wall of the seedling box 1 and the filter holes of the filter screen plate 9 are cleaned through the cleaning component 13, and then the water in the seedling box 1 can be input into the filter box 2 through the connecting component 6, and the residual bait, feces and other impurities in the water are filtered through the impurity removal mechanism 7, and then the filtered water is injected from the filter box 2 into the seedling box 1 through the connecting component 6, so as to achieve the purpose of replacing and recycling the water body and reduce the waste of water resources.

[0044] When in use, the connecting component 6 transports the water in the seedling box 1 to the filter box 2, and then the water first enters the filter net bag 702 in the filter frame 701. The solid impurities such as residual bait and feces in the water remain in the filter net bag 702. When too much residual bait and feces are collected, the filter net bag 702 can be taken out for treatment and replaced with a new filter net bag 702. The water after the initial filtration flows out through the fixed pipe 703 and falls on the multiple filter components 704. The multiple filter components 704 absorb the fine impurities and odors in the water, and then the filtered water is injected into the seedling box 1 again through the connecting component 6 to complete the filtration and recycling of the water.

[0045] In this embodiment: the multiple filter component 704 includes a filter cotton layer 7041 and an activated carbon layer 7042, and the filter cotton layer 7041 and the activated carbon layer 7042 are arranged in sequence from top to bottom.

[0046] The water after the initial filtration by the filter net bag 702 is discharged from the fixed pipe 703 and first passes through the filter cotton layer 7041. The filter cotton layer 7041 can filter out fine impurities in the water, and then falls on the activated carbon layer 7042. The activated carbon layer 7042 can absorb the odor in the water. After the filtration is completed, the water gathers at the bottom of the filter box 2 and is injected into the seedling box 1 through the connecting component 6.

The outlet of the second water pump 604 is connected to the second water outlet pipe 606, and the end of the second water outlet pipe 606 away from the second water pump 604 is located above the opening of the seedling box 1.

[0049] When in use, the first water pump 601 and the second water pump 604 are started at the same time, and the solenoid valve 5 on the connecting pipe 4 is opened. The first water pump 601 draws water in the seedling raising box 1 from the connecting pipe 4 through the first water inlet pipe 602, and injects the water into the filter frame 701 in the filter box 2 through the first water outlet pipe 603. When the water is filtered, the second water pump 604 draws the filtered water from the filter box 2 through the second water inlet pipe 605, and injects the water from above the opening of the seedling raising box 1 through the second water outlet pipe, so as to achieve the recycling of water and make the water in the seedling raising box 1 flow, so as to increase the oxygen in the water.

[0050] The first water pump 601 and the second water pump 604 are both of model: ISG32-200.

[0051] In this embodiment: a motor 10 is installed on one side of the seedling box 1, and the output shaft of the motor 10 is connected to a reciprocating screw 11, the reciprocating screw 11 is located on one side of the seedling box 1, and the two ends are respectively rotatably connected to the opposite sides of the seedling box 1, the reciprocating screw 11 extends along the width direction of the seedling box 1, and the cleaning assembly 13 can be pushed to move along the reciprocating screw 11 through the rotation of the reciprocating screw 11.

[0052] When the water in the seedling raising box 1 is extracted, some of the residual bait and feces will be attached to the bottom of the seedling raising box 1. The motor 10 is turned on, and the motor 10 drives the reciprocating screw 11 to rotate. The reciprocating screw 11 drives the cleaning component 13 to move back and forth. The residual bait and feces attached to the bottom of the seedling raising box 1 are cleaned by the cleaning component 13, and the cleaned residual bait and feces are discharged from the connecting hole 3 through the first water inlet pipe 602 into the filter box 2.

[0055] The reciprocating screw 11 drives the scraper 1301 and the brush 1302 to move back and forth synchronously. During the synchronous movement of the scraper 1301 and the brush 1302, the limit rod 12 can limit the scraper 1301 to prevent the scraper 1301 from rotating with the rotation of the reciprocating screw 11. At the same time, the scraper 1301 scrapes off the residual bait and feces attached to the bottom of the seedling box 1, and the brush 1302 can clean the filter holes on the filter mesh plate 9 to prevent the filter holes of the filter mesh plate 9 from being blocked by residual bait and feces.
