Description

Technical Field

[0001] This invention relates to the field of fish fry rearing technology, specifically a fish fry rearing box. Background Technology

[0002] In the aquaculture industry, fish fry rearing is a crucial step. Proper fish fry rearing techniques can not only improve the survival rate of fish fry but also significantly accelerate their growth, providing a stable foundation for subsequent aquaculture production. Traditional fish fry rearing boxes are typically just simple container designs.

[0003] Traditional fish fry rearing boxes typically use simple container designs, which can meet basic rearing needs to a certain extent. However, when feeding the rearing boxes, some feed falls onto the edges of the boxes and cannot fall into the boxes. This not only leads to serious feed waste and increases rearing costs, but also the accumulated feed may mold and deteriorate, affecting water quality and adversely impacting the growth environment of the fish fry.

[0004] Therefore, this invention proposes a fish fry rearing box to compensate for and improve the shortcomings of the prior art. Summary of the Invention

[0012] Furthermore, the swing mechanism includes a mounting rod fixedly connected to the bottom of the connecting rod, with both ends of the mounting rod rotatably connected to the protrusions on the upper surface of the rotating disk, and a first torsion spring sleeved on the outside of the mounting rod.

[0017] Beneficial effects:

[0018] 1. This device is equipped with a walking mechanism. The moving seat that moves along the top of the side wall of the tank drives the rotating sweeping roller to sweep the feed accumulated on the top of the side wall of the tank into the tank. On the one hand, it avoids feed waste, and on the other hand, it prevents the feed accumulated on the top of the side wall of the tank from becoming moldy and deteriorating and falling into the water, which helps to maintain the cleanliness and stability of the water quality.

[0019] 2. This device is equipped with a throwing mechanism that uses a rotating disc to scatter feed into the water. It can evenly scatter the feed on the water surface at a certain speed and angle, making the feed more widely and evenly distributed in the water, avoiding the phenomenon of some areas having too much feed and some areas having too little feed.

[0020] 3. This device is equipped with a swinging mechanism. When the feeding mechanism is spreading the feed, it can swing up and down. By swinging up and down, the feeding mechanism can spread the feed in a wider area. The feed can not only be evenly distributed in the horizontal direction, but also achieve a wider coverage in the vertical direction, ensuring that fish fry in different water layers can obtain food.

[0021] 4. This device is equipped with a collection mechanism that uses a rotating shaft to drive the filter plate to rotate, thereby retrieval of dead fish from the water. Timely removal of dead fish from the water can significantly reduce the accumulation of harmful substances, effectively maintain water quality, and provide a healthier living environment for fish. Dead fish can be retrieved while cleaning the feed piled up on the side walls and top of the tank, which not only reduces labor costs but also improves work efficiency. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] The present invention will be further described below with reference to embodiments.

[0033] See Figures 1 to 7 This embodiment of a fish fry rearing box includes a circular box body 10. A walking mechanism 20 for cleaning up fallen feed is provided on the top of the side wall of the box body 10. A scattering mechanism 30 for spreading feed is provided in the middle of the box body 10. A swinging mechanism 50 for increasing the spreading distance of feed is provided at the bottom of the scattering mechanism 30. A rotating mechanism 40 for increasing the spreading area of ​​feed is provided on the side of the walking mechanism 20. A collection mechanism 60 for scooping up dead fish is provided at the bottom of the rotating mechanism 40.

[0034] The walking mechanism 20 includes a movable seat 201 disposed on the top of the side wall of the box 10. A drive wheel 202 is rotatably connected to the bottom of the movable seat 201 and is rolled along the top of the side wall of the box 10. A limit wheel 203 is also symmetrically rotatably connected to the bottom of the movable seat 201 and is rolled along the side wall of the box 10. A drive shaft 207 is rotatably connected to the side of the movable seat 201. A cleaning roller 208 for cleaning the top of the side wall of the box 10 is fixedly connected to the end of the drive shaft 207 away from the movable seat 201. A first collection frame 212 for collecting feed is also fixedly connected to the side of the movable seat 201 and is bent along the outside of the box 10.

[0035] A drive motor 204 is fixedly connected inside the cavity of the movable seat 201. A worm gear 206 is fixedly connected to the output end of the drive motor 204. The end of the worm gear 206 away from the drive motor 204 is fixedly connected to the transmission shaft 207. A worm wheel 205 is also rotatably connected to the inner wall of the movable seat 201. The worm wheel 205 meshes with the worm gear 206. A main gear 209 is fixedly connected to the side of the worm wheel 205 coaxially. A secondary gear 210 is fixedly connected to the side of the drive wheel 202 coaxially. The secondary gear 210 and the main gear 209 are connected by a chain 211.

[0036] In practice, when it is necessary to clean the feed accumulated on the top of the side wall of the box 10, the drive motor 204 drives the worm gear 206 to rotate. The rotating worm gear 206 drives the cleaning roller 208 to rotate through the transmission shaft 207. The rotating cleaning roller 208 sweeps the accumulated feed into the water inside the box 10. At the same time, the worm gear 206 drives the worm wheel 205 to rotate. The worm wheel 205 synchronously drives the main gear 209 to rotate. The main gear 209 drives the secondary gear 210 to rotate through the chain 211. The rotating secondary gear 210 drives the drive motor 206 to rotate. As the wheel 202 rotates, the driving wheel 202 rolls along the top of the side wall of the tank 10. While the sweeping roller 208 sweeps off the feed, the moving seat 201 drives the sweeping roller 208 to move along the top of the side wall of the tank 10, thereby sweeping off the feed on the top of the entire tank 10. This avoids feed waste and prevents the feed piled on the top of the side wall of the tank 10 from becoming moldy and falling into the water, which helps maintain the cleanliness and stability of the water quality. At the same time, some of the feed that falls outside the tank 10 falls into the first collection frame 212.

[0037] The scattering mechanism 30 includes a column 301 fixedly connected to the middle of the box 10, a circular outer shell 303 above the column 301, connecting rods 302 symmetrically fixedly connected to the bottom of the outer shell 303, and a discharge port 304 for throwing feed on the side of the outer shell 303.

[0038] A rotating disk 305 is rotatably connected inside the outer shell 303. Multiple partitions 306 are fixedly connected at equal angles on the upper surface of the rotating disk 305. A feed hopper 307 is fixedly connected to the top of the outer shell 303 and is interconnected with the outer shell 303. A rotary motor 308 is fixedly connected to the bottom of the outer shell 303. The output end of the rotary motor 308 extends into the outer shell 303 and is fixedly connected to the lower surface of the rotating disk 305.

[0039] In actual operation, after the feed is put into the feed hopper 307, the feed falls into the outer shell 303. As the rotary motor 308 drives the rotating disk 305 to rotate rapidly, under the action of centrifugal force, the rotating disk 305 drives the baffle 306 to throw the falling feed out of the discharge port 304. The thrown feed is scattered into the water, which can evenly throw the feed to the water surface at a certain speed and angle, so that the feed is more widely and evenly distributed in the water body, avoiding the phenomenon of too much feed in some areas and too little feed in some areas.

[0040] The rotating mechanism 40 includes a rotating disk 404 rotatably connected to the top of the column 301. A vertical rod 401 is fixedly connected to the upper surface of the rotating disk 404. A horizontal rod 402 is fixedly connected to the top of the vertical rod 401. The end of the horizontal rod 402 away from the vertical rod 401 is fixedly connected to the side of the movable seat 201. A mounting bracket 403 is symmetrically fixedly connected to the bottom of the horizontal rod 402.

[0041] In actual operation, while the walking mechanism 20 moves along the top of the side wall of the box 10, the moving seat 201 drives the rotating disk 404 to rotate horizontally on the top of the column 301 through the horizontal bar 402 and the vertical bar 401. At the same time as the rotating disk 404 rotates horizontally, it drives the spreading mechanism 30 to rotate horizontally in sync, thereby expanding the spreading area of ​​the feed.

[0042] The swing mechanism 50 includes a mounting rod 503 fixedly connected to the bottom of the connecting rod 302. Both ends of the mounting rod 503 are rotatably connected to the protrusions on the upper surface of the rotating disk 404. A first torsion spring 504 is sleeved on the outside of the mounting rod 503. One end of the first torsion spring 504 is fixedly connected to the outside of the mounting rod 503, and the other end of the first torsion spring 504 is fixedly connected to the protrusions on the upper surface of the rotating disk 404.

[0043] The swing mechanism 50 also includes an inverted L-shaped rod 505 fixedly connected to the side of the outer shell 303. A roller 506 is fixedly connected to the vertical section of the L-shaped rod 505. A first ring 501 is fixedly connected to the outside of the column 301. An arc-shaped block 502 is fixedly connected to the upper surface of the first ring 501 at equal angles. The roller 506 is in rolling connection with the upper surface of the first ring 501.

[0044] In specific operation, while the rotating mechanism 40 drives the spreading mechanism 30 to rotate horizontally, the roller 506 rolls along the upper surface of the first ring 501. The roller 506 is blocked by the arc block 502, causing the roller 506 to move up and down. When the roller 506 moves to the top of the arc block 502, the roller 506 drives the L-shaped rod 505 to push the discharge port 304 of the outer shell 303 upward. At this time, the connecting rod 302 at the bottom of the outer shell 303 drives the mounting rod 503 to rotate synchronously. When the mounting rod 503 rotates, it stores force on the first torsion spring 504. When the roller 506 moves downward from the top of the arc block 502, under the torsion of the first torsion spring 504, it drives the discharge port 304 of the outer shell 303 to deflect downward, thereby causing the discharge port 304 to swing up and down. This can spread feed in a wider area. The feed can not only be evenly distributed in the horizontal direction, but also achieve a wider coverage in the vertical direction, ensuring that fish fry in different water layers can obtain food.

[0045] The collection mechanism 60 includes a rotating shaft 601 that is rotatably connected to the end of the mounting frame 403 away from the crossbar 402. A bracket 602 is symmetrically fixedly connected to the outside of the rotating shaft 601. A filter plate 603 for scooping dead fish is fixedly connected to the side of the bracket 602.

[0046] The collection mechanism 60 also includes a second collection frame 604 fixedly connected to the surface of the filter plate 603. The second collection frame 604 has symmetrically provided mounting holes 607 on the side wall of its opening, and the mounting holes 607 are far away from the filter screen. A trunnion 606 is rotatably connected inside each mounting hole 607. A baffle 605 is fixedly connected to the side of the trunnion 606. A second torsion spring 608 is sleeved on the outside of the trunnion 606. One end of the second torsion spring 608 is fixedly connected to the second collection frame 604, and the other end of the second torsion spring 608 is fixedly connected to the outside of the trunnion 606. A limiting block 611 is provided at the opening of the second collection frame 604 to prevent the baffle 605 from rotating outward.

[0047] A friction wheel 609 is fixedly connected to one end of the rotating shaft 601 near the column 301. A second ring 610 is rolledly connected to the side of the friction wheel 609. The second ring 610 is coaxially fixedly connected to the column 301.

[0048] In actual operation, while the walking mechanism 20 moves along the top of the side wall of the housing 10, the friction wheel 609 at one end of the rotating shaft 601 at the bottom of the mounting frame 403 rolls along the surface of the second ring 610, thereby driving the rotating shaft 601 to rotate. When the rotating shaft 601 rotates, it drives the filter plate 603 to scoop up the dead fish in the water onto the filter plate 603. When the filter plate 603 rotates to the highest point, under the action of gravity, the baffle 605 rotates inward toward the second collection frame 604, and the dead fish slide into the second collection frame 604. When the filter plate 603 rotates to the lowest point, under the action of gravity, the baffle 605 rotates outward toward the second collection frame 604, and the baffle 605 closes the opening of the second collection frame 604, thereby preventing the dead fish in the second collection frame 604 from falling back into the water.

[0049] Working principle:

[0050] During feeding, the feed is scattered into the water of the tank 10 by the throwing mechanism 30, and the feed accumulated on the top of the side wall of the tank 10 is swept into the water by the walking mechanism 20. At the same time, the walking mechanism 20 drives the throwing mechanism 30 to rotate horizontally through the rotating mechanism 40, thereby expanding the area of ​​feed scattering. When the throwing mechanism 30 rotates horizontally, it is driven to swing up and down back and forth by the swing mechanism 50, thereby expanding the throwing distance of feed. When the rotating mechanism 40 rotates horizontally, it drives the collecting mechanism 60 to scoop up dead fish from the water.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
