Description

Technical Field

[0001] The utility model relates to the technical field of feeding inducement test devices, in particular to an aquatic feed feeding inducement test device. Background Art

[0002] At present, in the process of aquaculture, in order to speed up the feeding speed of aquatic animals and increase the feeding amount, attractants are often added to the bait. When the bait is put into the water, the attractant dissolves and forms a chemical stimulation to the aquatic animals, thereby increasing the feeding speed and feeding amount, promoting growth, and increasing the breeding efficiency, while reducing nutrient loss and reducing pollution to the water environment. In order to obtain the attractant effect of different aquatic feeds and classify them accordingly, the attractant effect of aquatic feeds is often tested through aquatic feed attractant test equipment during aquatic feed production.

[0003] The Chinese patent authorization announcement number is CN214508804U, and its name is an aquatic feed attractant test device, which includes a test box with an opening at the upper end. A plurality of isolation components are arranged along the circumferential direction of the test box. The isolation components divide the interior of the test box into multiple feeding areas and a temporary holding area. The feeding areas are isolated from each other. The temporary holding areas are respectively connected to each feeding area. Partitions are respectively provided on the connecting passages between the temporary holding area and each feeding area. The partitions are used to isolate the temporary holding area from the feeding area. The temporary holding area is provided with baffles arranged opposite to each baffle, which divides the interior of the test box into multiple different test functional areas. An independent space is formed between the baffle and the corresponding connecting port, so that the space can be isolated from the taste of feed in other feeding areas without being affected by the taste of other feeds, thereby improving the accuracy of the test.

The bottom of the water tank 1 is provided with an air inlet pipe 11 connected to the annular tube 9, and the input end of the air inlet pipe 11 is provided with an oxygenator 12. The internal space of the water tank 1 can be divided into two parts from the inside to the outside by the No. 1 partition plate 3 and the plug-in board 5. The internal space is used for temporarily raising experimental fish, and the external space is used for putting different kinds of aquatic feed to be tested, and the external space can be further divided by the No. 2 partition plate 4. Dividing into four groups can avoid mixing of aquatic feed placed in each group of space, further improving the accuracy of the test. When the test water depth needs to be changed, the staff can directly stretch the water tank 1 upward. The top edge of the water tank 1 is provided with an outer edge protrusion to facilitate the staff to stretch it. At this time, the folding part 2 is extended, and the overall height of the water tank 1 becomes longer, so that the highest water level line in the water tank 1 also becomes higher. The staff can observe the attracting effect of different types of aquatic feed on fish at deeper water levels. When the oxygen content of the water body needs to be increased, air can be input into the annular tube 9 through the oxygenator 12, and the exhaust holes 10 opened on the annular tube 9 evenly disperse the air into the water body, thereby increasing the oxygen content of the water body. The staff can observe the attracting effect of different types of aquatic feed on fish under different oxygen contents in the water body. Holes are provided on the No. 1 partition plate 3 and the plug-in plate 5. When the activity space of the fish is restricted, it also ensures that the odor information of the aquatic feed can smoothly enter the internal space, thereby attracting the fish.

[0024] In this embodiment, specifically, a plurality of groups of slow flow plates 7 are arranged at intervals on the bottom wall of the water tank 1. The slow flow plates 7 are located between the first partition plate 3 and the annular tube 9. The slow flow plates 7 can block and restrict the flow direction of the water flow and change the direction of the water flow, so that the odor information of the aquatic feed can be fully received by the fish.

[0025] In this embodiment, specifically, the bottom wall of the water tank 1 is provided with several groups of fixing pins 8 for installing the No. 1 partition plate 3, the No. 2 partition plate 4 and the plug-in plate 5. The No. 1 partition plate 3, the No. 2 partition plate 4 and the plug-in plate 5 are plug-fitted with the fixing pins 8 to facilitate assembly and disassembly.

[0026] In this embodiment, specifically, a drainage groove 13 is opened in the center of the bottom wall of the water tank 1, and a drainage pipe 14 connected to the drainage groove 13 is provided at the bottom of the water tank 1. Control valves are provided on the air inlet pipe 11 and the drainage pipe 14. Several groups of water inlet pipes 15 are provided on the outside of the top of the water tank 1. The air inlet pipe 11 injects water into the water tank 1 for subsequent tests. After the test, the drainage pipe 14 is used to drain the water tank 1.

[0027] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
