The fixed barrel 101 is in the shape of a hollow cylindrical barrel with an open top wall. A vertical hollow rotating tube 102 is rotatably arranged at the center of the top wall of the base 100 and the center of the bottom wall of the inner cavity of the fixed barrel 101. A collecting barrel 103 for collecting aquatic seedlings is detachably arranged on the hollow rotating tube 102. A through hole 104 is opened on the inner and outer side walls of the collecting barrel 103. The water changing mechanism 200 is arranged inside the collecting barrel 103 and is used to inject clean water into the collecting barrel 103 and replace the clean water, and includes a vertical water outlet pipe 201 that rotates through the center of the upper and lower ends of the hollow rotating tube 102. The water outlet pipe 201 is located at one end of the collecting barrel 103 and is evenly provided with water outlet holes 202. The apertures of the water outlet holes 202 and the through holes 104 are smaller than the aquatic seedlings; The cleaning mechanism 300 is reciprocatingly lifted and disposed in the inner cavity of the fixed barrel 101 for cleaning the through hole 104 and the inner side of the fixed barrel 101, and includes an annular lifting ring 301 located between the fixed barrel 101 and the collecting barrel 103, and a circle of cleaning bristles 302 for cleaning the through hole 104 is evenly arranged on the inner side of the lifting ring 301, and an annular cleaning ring 304 for cleaning the inner side wall of the fixed barrel 101 is fixedly arranged on the outer side of the lifting ring 301 through two symmetrical connecting blocks 303; The driving mechanism 400 is disposed in the inner cavity of the base 100 to drive the hollow rotating tube 102 to drive the collecting bucket 103 to rotate, and at the same time drive the lifting ring 301 to lift and reciprocate; The top of the fixed barrel 101 is hingedly provided with an adapted top cover, which is used to seal the collecting barrel 103 inside the fixed barrel 101, and a lock is provided on the top cover; the top cover is not shown in the figure, and is in a hollow core shape with a closed upper end and an open bottom, and is mainly used to seal the collecting barrel 103 inside the fixed barrel 101 when the lifting ring 301 is lifted, so as to reduce the water droplets from rotating outward when the collecting barrel 103 rotates; The outer wall of the hollow rotating tube 102 is sealed and rotated through the center of the top wall of the base 100 and the center of the bottom wall of the inner cavity of the fixed barrel 101 through the first sealing bearing 105, and the outer wall of the water outlet pipe 201 is sealed and rotated through the center of the inner wall of the hollow rotating tube 102 through the second sealing bearing 106; the first sealing bearing 105 and the second sealing bearing 106 are provided to make the base 100 and the fixed barrel 101 relatively sealed, thereby reducing water leakage; The bottom of the side wall of the fixed barrel 101 is provided with a sewage pipe 117 connected to its inner cavity, and the other end of the sewage pipe 117 is connected to a sewage treatment device. The end of the sewage pipe 117 located outside the fixed barrel 101 is provided with a sewage valve 118; the sewage treatment device is not shown in the figure. When changing water, the sewage valve 118 can be opened to discharge the replaced sewage through the sewage pipe 117 to the sewage treatment device for sewage treatment, so as to avoid direct discharge to damage the environment and pollute the water source; The cleaning bristles 302 are made of a material with certain strength and toughness, the outer diameter of the cleaning bristles 302 is smaller than the inner diameter of the through hole 104, and the length of the cleaning bristles 302 is greater than the lateral spacing distance between the lifting ring 301 and the collecting bucket 103, and the outer ring of the cleaning ring 304 is provided with a circle of scraper ring 305, and the scraper ring 305 is interference fit with the inner wall of the fixed bucket 101; the cleaning bristles 302 and the scraper ring 305 can be made of rubber or other materials with certain elasticity. When the lifting ring 301 reciprocates, the cleaning bristles 302 can extend into the inner side of the through hole 104 to clean up the blocked impurities, and the cleaning ring 304 cleans the inner wall of the fixed bucket 101 through the scraper ring 305, thereby reducing the adhesion of impurities such as silt to the fixed bucket 101, which is conducive to maintaining the internal environment of the fixed bucket 101 relatively clean.

[0022] Example 2: Based on Example 1, please refer to Figures 9 to 14 A vertical hollow spline rod 107 is disposed at the upper end of the outer wall of the hollow rotating tube 102, a spline slot hole 108 adapted to be vertically inserted into the hollow spline rod 107 is opened at the center of the bottom wall of the collecting barrel 103, and the water outlet pipe 201 passes through the spline slot hole 108 in a vertical gap; A fixing frame 109 is symmetrically fixedly arranged at the bottom of the inner cavity of the collecting barrel 103, and a semicircular block-shaped sealing cover plate 111 is rotatably arranged on the side close to the two fixing frames 109 through a rotating shaft 110. The bottoms of the two sealing cover plates 111 are provided with sealing gaskets and are symmetrically arranged relative to the spline slot hole 108. A torsion spring is arranged on the rotating shaft 110, and the torsion spring applies a thrust to the sealing cover plate 111 so that the sealing cover plate 111 is closely attached to the bottom wall of the inner cavity of the collecting barrel 103 and is used to block the spline slot hole 108; Handles are fixedly provided on both sides of the top of the collection bucket 103, and anti-slip sleeves are provided at the gripping parts of the handles; When the collecting barrel 103 needs to be taken out from the inner cavity of the fixed barrel 101 to facilitate the centralized transfer of aquatic seedlings, the collecting barrel 103 can be lifted out of the fixed barrel 101 by the handle in the vertical direction. At this time, the hollow spline rod 107 slides vertically along the spline slot 108 until the water outlet pipe 201 is completely pulled out of the spline slot 108. The torsion spring applies a thrust to the sealing cover plate 111 so that the sealing cover plate 111 is closely attached to the bottom wall of the inner cavity of the collecting barrel 103 and is used to block the spline slot 108, thereby preventing the aquatic seedlings from falling from the spline slot 108 and being damaged. The inner cavity side wall of the collecting barrel 103 is fixedly provided with an arc-shaped receiving plate 112 at equal intervals, and the inner side wall of the receiving plate 112 is provided with an arc-shaped receiving groove 113, and the receiving groove 113 is open on one side and closed on the other side, and both the top and the bottom are open. The upper edge of the collecting barrel 103 is rotatably provided with an annular rotating ring 114 through a bearing ring, and the outer side of the rotating ring 114 is provided with anti-slip grooves 115. The bottom of the rotating ring 114 is fixedly provided with an arc-shaped sealing baffle 116 at equal intervals, and the sealing baffle 116 is provided one by one corresponding to the receiving groove 113, and the sealing baffle 116 is slidably provided on the inner side of the receiving groove 113 by interference fit. The bottom of the receiving plate 112 is fixedly connected to the inner cavity bottom of the collecting barrel 103, and a sealing gasket is provided between the bottom of the sealing baffle 116 and the inner cavity bottom of the collecting barrel 103. The sealing baffle 116 can be made of rubber or other materials with a certain elasticity. Before the collection barrel 103 is taken out from the inner cavity of the fixed barrel 101, the anti-slip groove 115 can be used to drive the rotating ring 114 to rotate, so that the sealing baffle 116 is partially rotated out of the inner wall of the storage groove 113, and the side of the sealing baffle 116 is tightly attached to the adjacent storage plate 112, so that the sealing baffle 116 and the storage plate 112 completely block the inner side of the through hole 104. After the two sealing cover plates 111 block the spline slot hole 108, the bottom and outer wall of the collection barrel 103 at this time form a relatively sealed area, thereby reducing the time for clean water to leak out, so that the clean water inside the collection barrel 103 can be continuously stored for a long time, which is enough for the transfer of aquatic seedlings and avoids the death of aquatic seedlings due to lack of water; It should be noted that in this embodiment, if the collection barrel 103 is provided with a sealing baffle 116 and a receiving plate 112 , the through holes 104 opened on the collection barrel 103 at this time can be opened only between adjacent receiving plates 112 , thereby reducing the opening amount of the through holes 104 .

When the water level is higher than the height of the water outlet 202, due to the principle of the communicating vessel, it is not necessary to start the pump 204 to save energy, and the clean water in the water tank 206 can also be sprayed out from the water outlet 202 through the water supply pipe 203, and the opening and closing size of the water control valve 210 can appropriately adjust the water output; When the water level is lower than the height of the water outlet 202, the pump 204 is started again to inject the clean water in the water tank 206 into the fixed barrel 101 to replace the water.

[0024] Embodiment 4: Based on Embodiment 1, the driving mechanism 400 includes a worm wheel 401 fixed to the lower end of the outer side of the hollow rotating tube 102, the worm wheel 401 is located in the inner cavity of the base 100, the inner cavity of the base 100 is rotatably provided with a worm 402 that meshes with the worm wheel 401, and the outer wall of the base 100 is fixedly provided with a servo motor 403, the output shaft of the servo motor 403 rotates and penetrates the side wall of the base 100 and is connected to the end of the worm 402 through a coupling; The inner wall of the fixed barrel 101 is installed with a vertical reciprocating screw rod 405 and a vertical guide slide rod 406 through a bracket 404. The reciprocating screw rod 405 and the guide slide rod 406 are located on the left and right sides of the collecting barrel 103. The reciprocating screw rod 405 is connected to one of the connecting blocks 303 to drive the lifting ring 301 to reciprocate and lift.

The outer wall of the hollow rotating tube 102 is located in the inner cavity of the fixed barrel 101 and is fixedly provided with a rotating disk 408. The collecting barrel 103 is placed on the top of the rotating disk 408. The outer side of the rotating disk 408 is provided with a circle of external teeth 409.

At the same time, the collecting barrel 103 is driven to rotate through the hollow spline rod 107 on the hollow rotating tube 102 and the spline slot hole 108 at the bottom of the collecting barrel 103, so that the collecting barrel 103 and the cleaning bristles 302 are further rotated relative to each other, so as to realize the cleaning of the through hole 104 at different angles; It should be noted that the servo motor 403 controls the speed at which the worm 402 rotates. In addition, the worm 402 and the worm wheel 401 have a relatively large transmission and rotate slowly. Therefore, the speed at which the collection barrel 103 rotates should not be too fast to reduce the impact on aquatic seedlings.
