[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0021] Refer to Figures 1-4 , a fry culturing device provided by the utility model includes a culture tank 3. A fixing ring 6 is connected inside the culture tank 3 through a fastener. A net bag 9 is fixedly connected to the lower end of the fixing ring 6. A support plate 10 is fixedly connected to the inner wall of the fixing ring 6. A reciprocating mechanism is installed inside the support plate 10, and the reciprocating mechanism is connected to the net bag 9 and drives the net bag 9 to vibrate. A fixing shaft 17 is fixedly connected to the bottom end inside the culture tank 3. A scraping plate 14 is rotatably connected to the circumferential surface of the fixing shaft 17, and the scraping plate 14 is attached to the culture tank 3. The utility model can intercept fry separately by using the net bag 9 during the water change process, so that the sewage, dirt and fry excrement inside the culture tank 3 can be smoothly discharged outwards, while the fry are not easily discharged, and thus the loss of fry is not easily caused, and the water change work can be successfully completed.
[0022] Furthermore, as Figure 3 shown, two drain pipes 2 and two valves 11 are fixedly connected to the circumferential surface of the culture tank 3. The two valves 11 are respectively fixedly connected to the two drain pipes 2. The two drain pipes 2 are respectively located at the left and right ends of the culture tank 3. By opening the two valves 11, the water inside the culture tank 3 can be discharged outwards along the two drain pipes 2, so that the drainage operation can be completed faster to facilitate water change.
[0023] Furthermore, as Figure 2 shown, a heat preservation sleeve 1 is sleeved on the circumferential surface of the culture tank 3. Two notches 12 are opened on the upper end surface of the heat preservation sleeve 1. The heat preservation sleeve 1 can keep the temperature of the culture tank 3, avoiding the water temperature inside the culture tank 3 being too low, which is not conducive to fry cultivation. The existence of the notches 12 facilitates the installation of the culture tank 3 driving the valves 11 and the drain pipes 2 into the heat preservation sleeve 1 through the notches 12.
[0024] Furthermore, as Figures 3-4As shown in the figure, the fastener includes a fixing plate 5, a mounting hole 18, a threaded rod 15 and a nut 16. Two fixing plates 5 are fixedly connected to the upper end of the fixing ring 6. Mounting holes 18 are provided on the upper end surfaces of the two fixing plates 5. Two threaded rods 15 are fixedly connected to the upper end of the breeding box 3. The two threaded rods 15 are respectively connected to the two fixing plates 5 through the two mounting holes 18. Nuts 16 are threadedly connected to the circumferential surfaces of the two threaded rods 15, and the nuts 16 are located above the fixing plates 5. By rotating the nuts 16 to disengage them from the threaded rods 15, the net bag 9 can be taken out from the inside of the breeding box 3 for replacement. By using the fixing plate 5 to be sleeved on the threaded rod 15 under the cooperation of the mounting hole 18 and then installing the nut 16 on the circumferential surface of the threaded rod 15, the fixing ring 6 and the net bag 9 can be stably located inside the breeding box 3 and are not easily separated from the breeding box 3 at will.
[0025] Furthermore, the reciprocating mechanism includes a circular plate 7, a sliding rod 13 and a spring 8. The sliding rod 13 is slidably connected inside the support plate 10. The upper end of the sliding rod 13 is fixedly connected to the circular plate 7. The sliding rod 13 is fixedly connected to the net bag 9. A spring 8 is sleeved on the circumferential surface of the sliding rod 13. One end of the spring 8 is fixedly connected to the circular plate 7, and the other end of the spring 8 is fixedly connected to the support plate 10. Pressing the circular plate 7 downward will drive the sliding rod 13 to move downward along the support plate 10, and the spring 8 will be compressed. The net bag 9 is pulled downward by the downward thrust of the sliding rod 13. Then releasing the circular plate 7, under the action of the spring 8, the sliding rod 13 and the circular plate 7 move upward to reset. Repeating this process can keep the net bag 9 in a vibrating state all the time, which is beneficial for the excrement of the fry and the feed residues inside the net bag 9 to smoothly fall into the breeding box 3 through the net bag 9.
[0026] Furthermore, as Figure 3 shown, the scraper 14 is in a U shape. A handle 4 is fixedly connected to the upper end of the scraper 14. The handle 4 is located above the breeding box 3. Holding the handle 4 by hand and driving the scraper 14 to rotate around the fixed shaft 17 can scrape the inner wall and the bottom end of the breeding box 3, so that the dirt attached to the inner wall of the breeding box 3 falls off, which is convenient for the sewage and the dirt to be discharged out together during the subsequent water change process. By regularly cleaning the breeding box 3, the inside of the breeding box 3 can be continuously maintained in a good breeding environment, which is more beneficial for the growth of the fry.
[0027] Working principle:
[0028] During use, fry are put into the net bag 9. Water is filled inside the breeding box 3, and the water will enter the net bag 9 to provide a living environment for the fry. At this time, fry can be cultured inside the breeding box 3. Then, by changing water and feeding regularly, the fry can grow rapidly. When it is necessary to change water, first rotate the scraper 14 to scrape off the dirt on the inner wall of the breeding box 3. Then, control the reciprocating mechanism to operate so that the excrement and feed residues of the fry inside the net bag 9 can also smoothly fall into the breeding box 3 through the net bag 9. Next, open the valve 11, and the sewage is discharged through the drain pipe 2. At the same time, clean water is added to the breeding box 3 and this continues until the inside of the breeding box 3 is filled with clean water, then close the valve 11 to complete the water change operation.
[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
