Description

Technical Field

[0001] The utility model relates to the technical field of swamp shrimp breeding, in particular to a swamp shrimp breeding cage for quickly separating seed shrimps. Background Art

[0002] A breeding cage is a type of equipment used in aquaculture, mainly for breeding and breeding aquatic organisms. This type of cage usually has a specific mesh size and structure to adapt to the needs of aquatic organisms at different growth stages. The design of the breeding cage takes into account the growth environment of the organisms, ensuring good water exchange, providing sufficient oxygen and food, and preventing the escape of organisms.

[0003] The existing swamp shrimp breeding cages have a single structure when in use, and there is no structure inside to separate the brood shrimp. Screening cannot be performed inside the cages. All the brood shrimp and shrimp fry need to be salvaged and screened, which affects the survival rate of the shrimp fry.

[0004] Therefore, in order to address the problem that the above-mentioned existing swamp shrimp breeding cages have a single structure when in use and do not have a structure inside to separate the brood shrimp, the brood shrimp and shrimp fry need to be salvaged and screened, which affects the survival rate of the shrimp fry. A swamp shrimp breeding cage that can quickly separate the brood shrimp can be designed. By setting a second pull rope, when the second pull rope is pulled, the ring will be driven to slide up along the column, and the ring will drive the screen plate to move up. At the same time, the first pull rope will be pulled. The first pull rope is wrapped around the outer surface of the first positioning ring, thereby driving the first positioning ring and the reset shaft to rotate. When the second pull rope is released, the reset shaft is reset, thereby driving the screen plate to descend. After the screen plate is repeatedly raised and lowered, the brood shrimp will remain on the upper surface of the screen plate, while the shrimp fry will remain under the screen plate, thereby achieving rapid separation.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] See also Figure 1-Figure 4The utility model provides an embodiment: a swamp shrimp breeding cage for quickly separating seed shrimps, comprising an upper frame 1; further comprising a first mounting groove 5, a reset shaft 6, a first positioning ring 7, a first pull rope 8, a collar 9, a screen plate 10 and a second pull rope 11. One end of a column 2 is mounted on the corners of the bottom surface of the upper frame 1, the other end of the column 2 is connected to the lower frame 3, and mesh belts 4 are arranged on the four outer surfaces and the bottom surface of the lower frame 3. First mounting grooves 5 are opened on both sides of the upper surface of the lower frame 3, and the inner surface of the first mounting groove 5 is rotatably connected to the reset shaft 6 on both sides. First positioning rings 7 are mounted on the front and rear ends of the outer surface of the reset shaft 6, and one end of the first pull rope 8 is wound around the outer surface of the first positioning ring 7. A ring 9 is provided on the surface, and the other end of the first pull rope 8 is connected to the ring 9. A sieve plate 10 is installed between the four rings 9. One end of the second pull rope 11 is connected to the upper surface of the ring 9. By setting the second pull rope 11, when the second pull rope 11 is pulled, the ring 9 will be driven to slide up along the column 2, and the ring 9 will drive the sieve plate 10 to move up, and at the same time, the first pull rope 8 will be pulled. The first pull rope 8 is wrapped around the outer surface of the first positioning ring 7, thereby driving the first positioning ring 7 and the reset shaft 6 to rotate. When the second pull rope 11 is released, the reset shaft 6 is reset, thereby driving the sieve plate 10 to descend. After the sieve plate 10 is repeatedly raised and lowered, the breeding shrimp will be left on the upper surface of the sieve plate 10, while the shrimp seedlings will be left under the sieve plate 10, thereby achieving rapid separation.

[0023] See also Figure 2-Figure 4 In this embodiment, second mounting grooves 12 are provided on the left and right sides of the upper surface of the upper frame 1. Mounting plates 13 are installed on the front and rear sides of the bottom inner surface of the second mounting groove 12. The opposite surfaces of the two mounting plates 13 are rotatably connected with a rotating rod 14. The outer surface of the rotating rod 14 is provided with a second positioning ring 15 on both the front and rear sides. The other end of the second pull rope 11 is connected to the outer surface of the second positioning ring 15. By providing the rotating rod 14, the second pull rope 11 can be driven when the rotating rod 14 is rotated, so that the second pull rope 11 is wrapped around the surface of the second positioning ring 15. The inner diameter of the collar 9 is slightly larger than the diameter of the column 2, and the collar 9 is slidably connected to the column 2. By setting the inner diameter of the collar 9 to be slightly larger than the diameter of the column 2, the shaking of the collar 9 when moving up and down can be reduced, and the smoothness of lifting can be improved. The rear surface of the mounting plate 13 on the rear side is rotatably connected with a rocker arm 16, and the front surface of the rocker arm 16 passes through the rear mounting plate 13 and is connected to the rear end of the rotating rod 14. By setting the rocker arm 16, the rotating rod 14 can be driven to rotate when the rocker arm 16 is shaken, which is convenient to operate and saves time and effort.

[0024] See also Figure 2-Figure 4In this embodiment, the outer surface of the rocker arm 16 is provided with an anti-slip sleeve 17, and the anti-slip sleeve 17 is made of rubber. By providing the anti-slip sleeve 17, the hand grip of the staff when shaking the rocker arm 16 can be increased to avoid slipping. The outer surface of the column 2 is provided with a buoyancy block 18 at the upper position, and the side surface of the buoyancy block 18 is provided with a slot 19. The buoyancy block 18 is slidably connected to the column 2 through the slot 19. By providing the buoyancy block 18, the entire device can be floated above the water surface of the aquaculture pond, so that the environment inside the cage is consistent with the environment of the aquaculture pond, thereby improving the survival rate of the aquaculture. The first pull rope 8 and the second pull rope 11 are composed of multiple strands of nylon thread. By using nylon thread to weave the first pull rope 8 and the second pull rope 11, they can have higher toughness and wear resistance, thereby achieving the purpose of increasing service life.

[0025] When working, by setting a rotating rod 14, the second pull rope 11 can be driven when the rotating rod 14 is rotated, so that the second pull rope 11 is wrapped around the surface of the second positioning ring 15. By setting the inner ring diameter of the ring 9 to be slightly larger than the diameter of the column 2, the shaking of the ring 9 when moving up and down can be reduced, thereby improving the smoothness of lifting and lowering. By setting a rocker arm 16, the rotating rod 14 can be driven to rotate when the rocker arm 16 is shaken, which is convenient to operate and saves time and effort. By setting an anti-slip sleeve 17, the hand grip of the staff when shaking the rocker arm 16 can be increased to avoid slipping. By setting a buoyancy block 18, the entire device can be floated above the water surface of the breeding pond, so that the environment inside the cage is consistent with the environment of the breeding pond, thereby improving the survival rate of the breeding. By using nylon line to weave the first pull rope 8 and the second pull rope 11, they can have higher toughness and wear resistance, thereby achieving the purpose of increasing service life.

[0026] Through the above steps, by setting the second pull rope 11, when the second pull rope 11 is pulled, the ring 9 will be driven to slide up along the column 2, and the ring 9 will drive the screen plate 10 to move up, and at the same time, the first pull rope 8 will be pulled. The first pull rope 8 is wrapped around the outer surface of the first positioning ring 7, thereby driving the first positioning ring 7 and the reset shaft 6 to rotate. When the second pull rope 11 is loosened, the reset shaft 6 is reset, thereby driving the screen plate 10 to descend. After the screen plate 10 is repeatedly raised and lowered, the breeding shrimp will be left on the upper surface of the screen plate 10, and the shrimp seedlings will be left under the screen plate 10, thereby achieving rapid separation, thereby solving the problem that the existing swamp shrimp breeding cage does not have a screening structure when in use, and the breeding shrimp cannot be quickly separated inside the cage. It is necessary to salvage all the shrimp seedlings and breeding shrimp inside for separation, affecting the survival rate.
