Description

Technical Field

[0001] This utility model relates to the field of crab seedling breeding technology, specifically a seedling selection and preservation device for swimming crabs. Background Technology

[0002] The three-spined swimming crab seedling selection and preservation device is a specialized piece of equipment in the field of crab seedling technology, used for the cultivation of three-spined swimming crab seedlings, the selection of high-quality individuals, and the preservation of superior germplasm. Its core function is to provide a suitable growth environment for three-spined swimming crab seedlings. By scientifically controlling key conditions such as feeding and water quality, it improves the survival rate and growth quality of crab seedlings. At the same time, it assists in the selection of seedlings that meet germplasm standards, providing a basic guarantee for the large-scale development of three-spined swimming crab farming and the protection of germplasm resources.

[0003] The existing breeding and preservation equipment for swimming crabs consists of breeding cages, feeding buckets, and water exchange pipes. The breeding cages provide habitat and growth space for the crab larvae. Feed is poured into the cages manually. The water exchange pipes are connected to an external water source. Valves are opened manually at regular intervals to drain the wastewater from the breeding cages and inject fresh water. During use, staff manually control the amount and frequency of feeding and refresh the water through the water exchange pipes to achieve basic breeding and preservation operations.

[0004] Existing seed preservation equipment can meet basic seedling needs well, but in actual application, feeding relies on manual operation, which makes it impossible to accurately control the amount of feed given at one time. This can easily lead to excessive feed causing water pollution, or insufficient feed causing uneven growth of crab seedlings, affecting the quality of seedlings. In addition, if treatment agents are added to the water to improve the water quality and then dumped directly, the treatment agents will not mix with the water sufficiently, making it difficult to achieve the ideal treatment effect. Furthermore, the direct discharge of untreated wastewater can easily cause environmental pollution.

[0005] To address the shortcomings of existing technologies, this invention proposes a breeding and preservation device for swimming crabs with three warts. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 - Figure 6 As shown, this utility model is a breeding and preservation device for swimming crabs, including a breeding cage 1 and a treatment tank 2. A water supply pipe 10 is fixedly connected to the bottom of the breeding cage 1, and a water supply pipe 2 is fixedly connected to the top of the treatment tank 2.

The input end of the water pump 11 is fixedly connected to one end of the water supply pipe 10, and the output end of the water pump 11 is fixedly connected to the top of the water supply pipe 2 12.

[0020] Specifically, the breeding cage 1 is used for the breeding and preservation of swimming crab seedlings, the treatment tank 2 is used for treating the breeding water, the water supply pipe 10 transports the water to be treated in the breeding cage 1, the water supply pipe 2 transports the water to the treatment tank 2, the installation box 3 provides installation space for the quantitative feeding component, the quantitative feeding component realizes the precise quantitative feeding of crab seedlings, the reciprocating stirring component makes the water treatment agent and water fully mixed, and the water pump 11 provides power for water transportation.

[0021] Please see Figure 1 - Figure 3 As shown, the quantitative feeding component includes a feeding tank 4 and a conveying pipe 6. The feeding tank 4 is fixedly connected to the top of the mounting box 3. A moving auger 5 is rotatably connected inside the feeding tank 4. The conveying pipe 6 is fixedly connected inside the mounting box 3. A feed pipe 7 is fixedly connected to the top of the conveying pipe 6. The feed pipe 7 is located at the bottom of the moving auger 5. A conveying auger 8 is rotatably connected inside the conveying pipe 6. A discharge pipe 9 is fixedly connected to the bottom of the conveying pipe 6. A drive component 1 is set on the top of the mounting box 3. The drive component 1 includes a second motor 22. The second motor 22 is fixedly connected to the top of the mounting box 3. Pulleys 23 are fixedly connected to the output end of the second motor 22 and the bottom outer periphery of the moving auger 5. A conveyor belt 24 is sleeved on the outer periphery of the two pulleys 23. A bevel gear 25 is fixedly connected to the output end of the second motor 22 and one end of the conveying auger 8. The two bevel gears 25 mesh with each other. An mounting block 26 is fixedly connected to the outer periphery of the feeding tank 4. An arch-breaking rod 27 is fixedly connected to the top of the mounting block 26.

[0022] Specifically, the feeding tank 4 is used to store crab seedling feed. When the auger 5 rotates, it conveys the feed downward to the feed pipe 7. The conveying pipe 6 provides an installation channel for the conveying auger 8 and a feed conveying channel. The feed pipe 7 guides the feed in the feeding tank 4 into the conveying pipe 6. When the conveying auger 8 rotates, it conveys the feed from the discharge pipe 9 to the breeding cage 1. The discharge pipe 9 guides the feed to fall accurately into the breeding cage 1. The second motor 22 provides power to the quantitative feeding component. The pulley 23 and the conveyor belt 24 cooperate to transmit the power of the second motor 22 to the auger 5. The bevel gear 25 cooperates to transmit the power of the second motor 22 to the conveying auger 8. The mounting block 26 provides an installation base for the anti-bridging rod 27. The anti-bridging rod 27 prevents the feed in the feeding tank 4 from clumping and ensures smooth feeding.

[0023] Please see Figure 1 , Figure 4 and Figure 6 As shown, the reciprocating stirring assembly includes a rotating rod 13 and two support blocks 14. The rotating rod 13 is rotatably connected to the top of the processing tank 2, and the two support blocks 14 are fixedly connected to the inner wall of the processing tank 2. A drive gear 15 is fixedly connected to the bottom of the rotating rod 13, and a rotating frame 16 is fixedly connected to the outer periphery of the rotating rod 13. A gear ring 17 is fixedly connected to the bottom of the rotating frame 16. Driven gears 18 are rotatably connected to the top of the two support blocks 14. The drive gear 15 and the two driven gears 18 mesh with each other, and the gear ring 17 and the two driven gears 18 mesh with each other. A stirring rod 19 is fixedly connected to the bottom of the two driven gears 18. A discharge pipe 20 is fixedly connected to the bottom of the processing tank 2. A second drive assembly is provided on the top of the processing tank 2. The second drive assembly includes a motor 21, which is fixedly installed on the top of the processing tank 2. The output end of the motor 21 is fixedly connected to the top of the rotating rod 13.

[0024] Specifically, the rotating rod 13 drives the driving gear 15 and the rotating frame 16 to rotate synchronously. The support block 14 provides installation and support for the driven gear 18. The driving gear 15 and the gear ring 17 alternately mesh with the driven gear 18. Since both the driving gear 15 and the gear ring 17 are half-tooth designs, the two driven gears 18 can rotate alternately in the forward and reverse directions. The rotating frame 16 drives the gear ring 17 to rotate synchronously with the rotating rod 13. The driven gear 18 transmits power to the stirring rod 19. When the stirring rod 19 rotates, it stirs the water and the treatment agent. The discharge pipe 20 discharges the treated water that meets the standards. The motor 21 provides rotational power to the rotating rod 13.

[0025] The working principle of this utility model is as follows: When it is necessary to feed the crab seedlings in the breeding cage 1 in a quantitative manner, the second motor 22 is started. The output end of the second motor 22 drives the outer pulley 23 to rotate. The pulley 23 drives the moving auger 5 to rotate synchronously through the conveyor belt 24. The unclogging rod 27 breaks up the clumps of feed under the action of the moving auger 5. The broken feed is pushed by the moving auger 5 and falls into the conveying pipe 6 below through the feed pipe 7. At the same time, the bevel gear 25 at the output end of the second motor 22 drives the bevel gear 25 at one end of the conveying auger 8 to rotate, so that the conveying auger 8 in the conveying pipe 6 rotates, and the feed is accurately and quantitatively conveyed from the feed pipe 9 at the bottom of the conveying pipe 6 to the breeding cage 1, thereby realizing the precise quantitative feeding of crab seedlings.

[0026] When the water in the breeding cage 1 needs to be treated, the water pump 11 at the top of the treatment tank 2 is started. The water pump 11 draws the water to be treated from the breeding cage 1 through the water supply pipe 10, and then transports it to the treatment tank 2 through the water supply pipe 12. Then, water treatment agent is added to the treatment tank 2, and the motor 21 is started. The output end of the motor 21 drives the rotating rod 13 to rotate inside the treatment tank 2. The driving gear 15 at the bottom of the rotating rod 13 and the toothed ring 17 at the bottom of the outer rotating frame 16 rotate synchronously. Since the driving gear 15 and the toothed ring 17 are both half-tooth designs, the driving gear 15 and the toothed ring 17 alternately mesh with the two driven gears 18 at the top of the support block 14, so that the driven gears 18 drive the stirring rod 19 at the bottom to rotate back and forth inside the treatment tank 2. The treated water that meets the standards is discharged from the discharge pipe 20 at the bottom of the treatment tank 2, so that the treatment agent and the water are evenly mixed before being discharged.

[0027] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
