DETAILED DESCRIPTION
[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.
[0017] Please refer to Figure 1 - Figure 3 The utility model provides the following technical schemes:
[0018] The shrimp fry separation tank 2 is provided with an opening 5 on one side of the width direction, and a sealing plate is installed at the opening 5 to seal the opening 5. First and second drainage ports 7 and 8 are respectively arranged on the two side walls of the length direction of the shrimp fry separation tank 2. A partition plate 9 is arranged inside the shrimp fry separation tank 2, and the shrimp fry separation tank 2 is divided into a large fry cabin 10 and a large fry cabin 11 by the partition plate 9. A bait box is arranged in the large fry cabin 11, so that the shrimp fry can better separate and move. The opening 5 is arranged on the side wall of the large fry cabin 11. The partition plate 9 is provided with screen holes of uniform size and uniform distribution, and the size of the screen holes is only suitable for small shrimp fry to pass through. An adsorption sponge is arranged at the bottom of the large fry cabin 11, which can better precipitate excrement. The adsorption sponge at the bottom of the large fry cabin 11 can be replaced and cleaned through the opening 5.
[0019] A support table 15 for the shrimp fry separation tank 2 is arranged above the bottom plate 1. The first and second occupation tanks 3 and 4 are arranged on the two sides of the support table 15. The first and second drainage ports 7 and 8 are respectively arranged above the first and second occupation tanks 3 and 4. The first and second occupation tanks 3 and 4 are provided with adsorption sponges at the bottom. Third and fourth drainage ports 16 and 17 are respectively arranged on the outer side walls of the first and second occupation tanks 3 and 4.
[0020] Water outlet assemblies 12 are symmetrically arranged at both ends of the top of the large fry cabin 10 and the large fry cabin 11. The water outlet assembly 12 comprises a fixed box, a water inlet pipe and a plurality of water outlets. The fixed box is installed above the shrimp fry separation tank. The water inlet pipe is connected with the plurality of water outlets through a branch pipe. The water outlet assembly at the top of the large fry cabin 11 is connected with a tap water pipe. The tap water pipe is connected with an electric control valve. A water level sensor is electrically connected with a controller. The controller is used in matching with the electric control valve.
[0021] Valves are respectively arranged on the first, second, third and fourth drainage ports. The valves are used to control the transfer of the shrimp fry.
[0022] A water circulation mechanism 13 is arranged on one side of the outside of the shrimp fry separation tank 2. The water circulation mechanism 13 comprises an external water pump 1301, a water outlet 1302, a water return port 1303 and a filter sponge. The water outlet 1302 and the water return port 1303 are both pipe openings of water pipes. The water outlet is connected with the large fry cabin 11. The water return port 1303 is connected with the water outlet assembly at the top of the large fry cabin 10. When the external water pump works, the water in the large fry cabin 11 is pumped out, and the pumped-out water returns to the shrimp fry separation tank 2 through the water outlet assembly at the top of the large fry cabin 10 to form water movement. The filter sponge installed at the water return port 1303 can effectively purify the water quality. A water level sensor and a temperature sensor are installed inside the shrimp fry separation tank.
[0023] Put the bait box in the seedling cabin, and seal the opening with the sealing plate. At this point, it is necessary to confirm that the adsorption sponge at the bottom of the seedling cabin is cleaned and replaced. Then, the prawn seedlings are poured into the prawn seedling separation box, and the water circulation device is turned on to guide and filter the water flow. Under the action of the bait box and the water flow guidance, the small prawn seedlings start to transfer to the seedling cabin through the screen holes of the screen plate. After the transfer process, the valves of the first drain and the second drain are turned, and the prawn seedlings in the large seedling cabin and the small seedling cabin are transferred to the first occupation box and the second occupation box for cultivation, respectively. After the temporary cultivation is completed, the prawn seedlings are transferred to the cultivation area for cultivation.
