Description

Technical Field

[0001] The invention relates to the technical field of fish fry salvaging, in particular to a fish fry salvaging device for fishery breeding. Background Art

[0002] In actual fish farming, after the fry are grown and cultivated, they need to be salvaged for sale or changed ponds. The size of the fry is closely related to the economic value. During the breeding process, regular salvaging of the fry for pond division, grading or sales is an important part of breeding management, which helps to optimize the breeding density, reduce the spread of diseases, and improve breeding efficiency. In large fish ponds, salvaging with a bottom net will damage the mud bottom of the fish pond. In order to reduce the impact on the water ecology, it is usually necessary to use a trapping net for salvaging. The current fry salvaging device for fish farming is not convenient for automatic fry grading, trapping and salvaging. The traditional screening and salvaging method causes great damage to the fry. At the same time, after the trapped fish food is eaten, the fry are easy to swim out of the trapping net. It is not convenient to automatically control the closed trapping net, and it is not convenient to manually grasp the time to raise the net. The method of manually putting food wastes a lot of food, is not convenient for isolation and luring, and is also not convenient for automatic oxygenation protection. The gathering of fry is easy to cause hypoxia, and impurities in the fish pond are easy to block the trapping net. Summary of the invention

[0041] In the disclosed embodiment, the fasting closure member 6 comprises: a closed limiting rod 601, a limiting plate 6011, a rotating shaft 602 and a torsion spring connecting ring 603.

The structure can use the trapping member 4 to monitor the remaining fish food in real time, and the closed plate 1012 can be closed after the fish food is eaten, so as to ensure the capture of the fry, avoid the inconvenience of manual monitoring of the fish food, and the difficulty in controlling the time of the net. The control method of the structure is simple and direct, which can ensure that the fry are not graded and isolated. The same size of fry are quickly salvaged to avoid wasting fish food and causing a large number of fish to swim out of the closing plate 1012 after the food is used up. As the fish food inside the fish food tube 401 is eaten, until the propulsion tube 404 drives the micro switch 405 to squeeze into the fish food tube 401, the closing electromagnet 607 is connected to the electromagnetic suction limit plate 6011. At this time, the rotating shaft 602 will drive the closing plate 1012 to rotate, and the slots on the closing plate 1012 will be misaligned with the slots on the grading plate 1011 to achieve closure and prevent the fry from escaping, so that the staff can take out the fry for subsequent salvage.

[0042] Embodiment 2, on the basis of embodiment 1, the oxygen filling protective member 7 comprises: a driving motor 701, a rotating rod 702, an exhaust hole 7021 and an exhaust groove 7022, the driving motor 701 is waterproofed, and the driving motor 701 is fixedly mounted on the motor frame 102; the rotating rod 702 is fixedly mounted on the output shaft of the driving motor 701; the exhaust hole 7021 is opened on the rotating rod 702; the exhaust grooves 7022 are respectively opened on the front and rear sides of the rotating rod 702; the two exhaust grooves 7022 The oxygenation protection member 7 further comprises: an air guide cover 703 and an air connection pipe 704, the air guide cover 703 is fixedly mounted on the end of the rotary shaft 602; the air guide cover 703 is rotatably sleeved on the side of the rotary rod 702; the air guide cover 703 is fixedly connected with an air connection pipe 704, and the air connection pipe 704 passes through the salvage connection ring 101; the air connection pipe 704 is externally connected with an air pump; the air guide cover 703 is connected to the exhaust hole 7021, and the oxygenation protection member 7 is used, which can be used in the process of trapping and salvaging fry. In the process, oxygen is supplemented for the fry, which can prevent the fry from over-gathering and consuming too much oxygen to cause hypoxia. At the same time, the oxygenation protection member 7 can be used to control the jet cleaning grading plate 1011 to prevent the slots on the grading plate 1011 from adhering to impurities, which can play a cleaning role. The present structure adopts a rotatable rotating rod 702, which can realize rotation and comprehensive oxygenation protection. During the rotation process, the air guide cover 703 can supply air in real time, and the rotating rod 702 is driven to rotate by the driving motor 701, and the air is supplied by the air pump connected to the air pipe 704 for oxygenation. The oxygen is introduced into the exhaust hole 7021 through the air guide cover 703, and can be evenly discharged through the exhaust groove 7022. When the rotating rod 702 rotates, the air guide cover 703 will rotate on the rotating rod 702 to perform adaptation work, which will not affect the rotation of the rotating rod 702 and realize oxygenation. At the same time, the exhaust method can play a role in clearing and cleaning the grading plate 1011 and the trapping net 202, and the structure is simpler and more reasonable.

[0043] The working principle of this embodiment is as follows: insert the bottom shaft 301 into the bottom of the fish pond for positioning, and use the anti-sinking plate 302 to assist in increasing resistance. The fish guard connector 2 is threadedly connected to the salvage connection ring 101 for assembly. After the fry are trapped, the salvage connection ring 101 and the trapping net 202 are salvaged from the water together, and the fry can be dumped out by rotating and disassembling the docking connection ring 201. Before fishing, the lower pressure cover 502 is rotated to open, and fish food is put in from the supplementary connection tube 501 to push the plug. 503 can be convenient for squeezing fish food into the supplementary connecting tube 501. The trapping net 202 is a soft mesh structure, which can pull the propulsion tube 404 backward across the trapping net 202 to prevent the propulsion disk 4021 from blocking the supplementary connecting tube 501. At this time, the supplementary connecting tube 501 will continue to add fish food to the fish food tube 401 for replenishment. As the fry pass through the three grading plates 1011 and enter the trapping net 202 to eat the fish food particles, the tension spring 403 will pull the propulsion shaft 402 in real time during the process of the particles being eaten, so that the fish food particles can be brought into the fish food tube 401. The push plate 4021 is driven to move, and the vacant fish food in the leaking food slot 4011 is compensated and pushed forward to ensure the supply of fish food; under the pressure of the torsion spring 604, the slots on the closing plate 1012 and the grading plate 1011 can be aligned, and the limit plate 6011 plays the role of the limit swing plate 605. As the fish food in the fish food barrel 401 is eaten, the push cylinder 404 moves to adapt to the amount of fish food, driving the micro switch 405 to move together, until the push cylinder 404 drives the micro switch 405 to squeeze to the end of the fish food barrel 401 At this time, the closing electromagnet 607 is connected to the electromagnetic suction limit plate 6011, and the rotating shaft 602 will drive the closing plate 1012 to rotate, and the slots on the closing plate 1012 will be misaligned with the slots on the grading plate 1011 to achieve closure and prevent the fry from escaping; the driving motor 701 drives the rotating rod 702 to rotate, and the air pump connected to the air pipe 704 is used to supply air for oxygenation, and the oxygen is introduced into the exhaust hole 7021 through the air guide cover 703, and can be evenly discharged through the exhaust groove 7022 to achieve oxygenation.
