[0012] As a preferred embodiment of this utility model, a drain pipe is fixedly connected to the lower front of the box, and a valve is fixedly installed on the surface of the drain pipe.

[0013] Compared with the prior art, this utility model provides a seedling collection device for aquatic seedling ponds, which has the following beneficial effects: 1. This aquatic seedling collection device for a breeding pond, through the inclusion of a movable component, enables convenient and rapid movement of the seedling collection device while ensuring its stability. During use, the control equipment activates four hydraulic push rods simultaneously. The inner rods of the hydraulic push rods extend, pushing out the casters and supporting the housing. The seedling collection device is then moved to below the outlet of the aquatic seedling pond. The hydraulic push rods are then activated again, causing the inner rods to retract and slowly raise the casters, bringing the housing into contact with the ground. This increases the contact area, facilitating movement of the seedling collection device and maintaining its stability. It also prevents water flow impact from causing the housing to shift, thus improving the stability and convenience of using the aquatic seedling collection device for aquatic seedling ponds.

[0014] 2. This aquatic seedling collection device, through the installation of a lifting component, a damage-prevention falling component, and a collection component, achieves the purpose of rapid and damage-preventive seedling collection. In use, after moving the seedling collection device below the outlet of the aquatic seedling pond, place the end of the ten-mesh nylon mesh with the keel ring into the through-hole of the box body. The locking ring is engaged in the fixed ring groove. Start the drive motor; the dustproof and corrosion-resistant screw rod moves downwards along with the moving parts, causing the limiting ring plate of the limiting cylinder to engage in the limiting ring groove. The conical bucket is perpendicular to the middle of the ten-mesh nylon mesh. Open the spawn outlet of the aquatic seedling pond, and the seedlings and water fall into the ten-mesh nylon net through the limiting cylinder and conical hopper. The silicone inner lining is elastic, reducing damage during seedling collection. The water is discharged from the drain pipe, thus quickly collecting the seedlings. After collection, the moving part rises, taking the limiting cylinder with it, making it easy to remove the collection components. This avoids the need for manual hand-held nets for collection, which results in a smaller number of seedlings collected and is more likely to damage the seedlings, affecting their survival rate. It helps reduce labor intensity and improve the speed of seedling collection. Attached Figure Description

The lifting assembly 3 includes a drive motor 301, a dustproof and corrosion-resistant lead screw 302, a moving part 303, and a mounting frame 304. The anti-damage falling assembly 4 is installed on both sides of the inner wall of the mounting frame 304. The anti-damage falling assembly 4 includes a limiting cylinder 401, a limiting ring plate 402, a conical bucket 403, and a silicone inner liner 404. A through-hole 5, a limiting ring groove 6, and a fixing ring groove 7 are provided on the top surface of the box 1. A collection component 8 is snapped into the inside of the fixing ring groove 7. The collection component 8 includes a snap-fit ​​ring 801, a ten-mesh nylon mesh 802, and a keel ring 803. Two movable components 9 are arranged on both sides of the housing 1. The movable components 9 include a fixing part 901, a connecting hollow shell 902, a hydraulic push rod 903 and a caster wheel 904.

[0019] Specifically, the lifting assembly 3 includes a drive motor 301 fixedly connected to the top of the equipment frame 2. The output end of the drive motor 301 is fixedly connected to a dustproof and corrosion-resistant lead screw 302. A movable part 303 is threadedly connected to the surface of the dustproof and corrosion-resistant lead screw 302. A mounting bracket 304 is welded to one end of the movable part 303.

[0020] In this embodiment, the drive motor 301 is started, and the dustproof and corrosion-resistant lead screw 302 moves the moving part 303 downward, so that the limiting ring plate 402 of the limiting cylinder 401 is stuck in the limiting ring groove 6, and the conical bucket 403 is perpendicular to the middle of the ten-mesh nylon net 802. After collection is completed, the moving part 303 is raised, taking the limiting cylinder 401 up, so that the collection component 8 can be taken out.

[0021] Specifically, sliding rods 10 are fixedly connected to both ends of the inner top wall of the equipment frame 2, and the sliding rods 10 are connected through both sides of the surface of the moving part 303.

[0022] In this embodiment, the two sides of the movable part 303 slide on the sliding rod 10 to prevent the dustproof and corrosion-resistant lead screw 302 from shifting when it rotates.

[0023] Specifically, the anti-damage fall assembly 4 includes limiting cylinders 401 welded to both sides of the inner wall of the mounting frame 304. A limiting ring plate 402 is fixedly connected to the outer periphery of the limiting cylinder 401. A conical bucket 403 is welded to the bottom end of the limiting cylinder 401. A silicone inner liner 404 is embedded in the inner wall of the limiting cylinder 401 and the conical bucket 403.

[0024] In this embodiment, the conical hopper 403 is perpendicular to the middle of the ten-mesh nylon net 802, opening the spawn outlet of the aquatic seedling pond. Seedlings and water fall into the ten-mesh nylon net 802 through the limiting cylinder 401 and the conical hopper 403. The silicone inner liner 404 is elastic, reducing damage during the seedling collection process.

[0025] Specifically, the collecting component 8 includes a snap-fit ​​ring 801 that snaps into the inside of the fixing ring groove 7. A ten-mesh nylon mesh 802 is fixedly connected to the inner wall of the snap-fit ​​ring 801, and a keel ring 803 is fixedly provided at the bottom end of the ten-mesh nylon mesh 802.

[0026] In this embodiment, when in use, after moving the seedling collection device below the spawning port of the aquatic seedling pond, one end of the ten-mesh nylon net 802 with the keel ring 803 is placed into the through-hole 5 of the box 1, and the snap ring 801 is snapped into the fixing ring groove 7.

[0027] Specifically, the moving component 9 includes two fixing parts 901 fixedly connected to both sides of the housing 1. One end of the fixing part 901 is welded to a connecting hollow shell 902. A hydraulic push rod 903 is fixedly connected inside the connecting hollow shell 902. A caster wheel 904 is fixedly connected to the bottom end of the hydraulic push rod 903. A control device 11 is fixedly installed on the upper surface of one side of the housing 1. One side of the control device 11 is electrically connected to one side of the four hydraulic push rods 903 and the control end of the drive motor 301 via power lines.

[0028] In this embodiment, during use, the control device 11 controls the simultaneous activation of four hydraulic push rods 903. The inner rods of the hydraulic push rods 903 extend, pushing out the casters 904 and supporting the box 1. Then, the seedling collection device is moved to below the spawn outlet of the aquatic seedling pond. Then, the hydraulic push rods 903 are activated again, and the inner rods of the hydraulic push rods 903 retract, causing the casters 904 to slowly rise, so that the box 1 contacts the ground, increasing the contact area.

[0029] Specifically, a drain pipe 12 is fixedly connected to the lower front of the box 1, and a valve is fixedly installed on the surface of the drain pipe 12.

[0030] In this implementation scheme, water is discharged from the drain pipe 12, thereby enabling rapid collection of seedlings.

[0031] The working principle and usage process of this utility model are as follows: In use, after moving the seedling collection device below the outlet of the aquatic seedling pond, the control device 11 controls the simultaneous activation of four hydraulic push rods 903. The inner rods of the hydraulic push rods 903 extend, pushing out the casters 904 and supporting the housing 1. Then, the seedling collection device is moved below the outlet of the aquatic seedling pond. Next, the hydraulic push rods 903 are activated again, causing the inner rods of the hydraulic push rods 903 to retract, slowly raising the casters 904 until the housing 1 contacts the ground. This activates the drive motor 301, and the dustproof and corrosion-resistant lead screw... 302 moves downwards with the moving part 303, causing the limiting ring plate 402 of the limiting cylinder 401 to be locked in the limiting ring groove 6. The conical bucket 403 is perpendicular to the middle of the ten-mesh nylon net 802, opening the seedling outlet of the aquatic seedling pond. Seedlings and water fall into the ten-mesh nylon net 802 through the limiting cylinder 401 and the conical bucket 403. The silicone inner liner 404 is elastic, reducing damage during seedling collection. After collection, the moving part 303 rises, taking the limiting cylinder 401 with it, making it easy to remove the collection component 8. This process is repeated to collect seedlings from the next aquatic seedling pond.

[0032] In summary, this aquatic seedling collection device, by incorporating a movable component 9, enables convenient and rapid movement of the seedling collection device while ensuring its stability. During use, the control device 11 simultaneously activates four hydraulic push rods 903. The inner rods of the hydraulic push rods 903 extend, pushing out the casters 904 and lifting the housing 1. The seedling collection device is then moved below the outlet of the aquatic seedling pond. The hydraulic push rods 903 are then activated again, causing their inner rods to retract and slowly raise the casters 904, bringing the housing 1 into contact with the ground and increasing the contact area. This facilitates movement of the seedling collection device and maintains its stability, preventing water flow impact that could cause the housing 1 to move. This enhances the stability and convenience of using the aquatic seedling collection device. By setting up the lifting component 3, the damage-preventing falling component 4, and the collecting component 8, the purpose of rapid and damage-preventing seedling collection can be achieved. In use, after moving the seedling collecting device below the spawning outlet of the aquaculture seedling pond, place one end of the ten-mesh nylon mesh 802 with the keel ring 803 into the through-hole 5 of the box 1. The snap ring 801 is snapped into the fixed ring groove 7. Start the drive motor 301, and the dustproof and corrosion-resistant lead screw 302 moves downwards with the moving part 303, causing the limiting ring plate 402 of the limiting cylinder 401 to snap into the limiting ring groove 6. The conical bucket 403 is vertically positioned in the middle of the ten-mesh nylon mesh 802. The aquatic seedling pond is opened, and the seedlings and water fall into the ten-mesh nylon net 802 through the limiting cylinder 401 and the conical hopper 403. The silicone inner liner 404 is elastic, reducing damage during the seedling collection process. The water is discharged from the drain pipe 12, thus quickly collecting the seedlings. After collection, the moving part 303 rises, taking the limiting cylinder 401 with it, making it easy to remove the collection component 8. This avoids manual collection with a net bag, which results in a smaller number of seedlings collected and is more likely to damage the seedlings, affecting their survival rate. It helps to reduce labor intensity and improve the speed of seedling collection.
