[0003] Aquaculture is one of the important industries in China's agriculture. With the increase of population and the increase of demand for high-quality protein, aquaculture has become an important way to obtain food and economic benefits, and has developed rapidly and contributed huge wealth to the national economy. Modern aquaculture technology is constantly innovating, including artificial ecological environment breeding, multi-species three-dimensional breeding, etc. At the same time, compound feed, large-scale automated equipment and information technology are used to improve efficiency and sustainability. When breeding, the feeding time, feeding amount and feeding area need to be reasonably configured according to the environment and the growth law of fish to speed up the growth of fish groups.

[0004] The existing feed feeding equipment usually concentrates the area of throwing feed in a certain area when feeding fish groups, which will cause a large number of fish groups to rush for feed, so that part of the fish cannot get feed and affect growth, thereby reducing the uniformity of fish growth, and in severe cases, the water quality in the area will change. When a large number of fish groups gather in an area, it is easy to cause oxygen deficiency in the area, causing fish groups to appear hypoxia phenomenon, reducing the survival rate of fish groups. Therefore, an automatic feeding system for marine aquaculture net cages is proposed. SUMMARY

[0008] As a preferred technical scheme of the automatic feeding system for the marine culture net cage, the inside of the feed tank is provided with a semicircular plate, and one side of the feeding box is arranged to move in an arc-shaped track on the surface of the semicircular plate.

[0009] As a preferred technical scheme of the automatic feeding system for the marine culture net cage, a feed inlet is arranged on one side of the feed tank, the three groups of feeding boxes are arrayed on the surface of the long plate, and the feeding boxes are in the shape of spoons.

[0010] As a preferred technical scheme of the automatic feeding system for the marine culture net cage, the partition strip is provided with three groups, the heights of the three groups of partition strips are arranged in descending order, one end of the spring is fixedly connected to the arc-shaped plate, and the other end of the spring is fixedly connected to the vertical plate.

[0011] As a preferred technical scheme of the automatic feeding system for the marine culture net cage, the rotating assembly comprises an L-shaped connecting plate fixedly connected to the front end of the base, a servo motor two being installed on the L-shaped connecting plate, a sleeve fixedly connected to the output end of the servo motor two, and a reciprocating screw rod rotatably connected to the inside of the sleeve.

[0012] As a preferred technical scheme of the automatic feeding system for the marine culture net cage, an extrusion plate is welded to the end of the reciprocating screw rod away from the sleeve, an oil groove is arranged in the inside of the base, and an arc-shaped circular block groove is arranged in the inside of the base on the side of the oil groove away from the extrusion plate.

[0013] As an automatic feeding system of a marine culture net cage of the present application, the arc-shaped groove is internally slidably connected with a circular block, one side of the circular block is welded with a connecting plate, and the connecting plate is fixedly connected with a rotating disc at a side away from the circular block.

After the first fish school is fed, the second feeding is performed by rotating the feed box, which can better expand the fan angle during feeding and cover a wider area, so that the fish school can more evenly ingest the feed, thereby improving the feeding efficiency.

[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0031] The following describes an embodiment of the present invention based on its overall structure.

[0032] An automatic feeding system for marine aquaculture cages, such as Figures 1-9 As shown, it includes a base 100 installed at the four corners of the top of the deep-sea cage, a feed box 110 is provided on the top of the base 100, a feeding assembly 200 is provided inside the feed box 110, and a rotating assembly 300 is provided inside the base 100;

[0033] The feeding assembly 200 comprises a servo motor 210 fixedly connected to the front end of the feed box 110, the output end of the servo motor 210 is fixedly connected with a long shaft 220, the surface of the long shaft 220 is fixedly connected with a long plate 230, the surface of the long plate 230 is fixedly connected with three groups of feeding boxes 240, the top of the three groups of feeding boxes 240 is fixedly connected with two arc baffles 250 on both sides, two groups of vertical plates 270 fixedly connected to the top of the feeding box 240 are arranged between the two arc baffles 250, an arc-shaped groove 251 is arranged between the arc baffle 250 and the vertical plate 270, a straight groove 271 is arranged between the two groups of vertical plates 270, a partition strip 260 fixedly connected to one side of the feeding box 240 is arranged on one side of the arc baffle 250, a base rod 280 is fixedly connected in the two groups of vertical plates 270, an arc-shaped plate 290 is rotatably connected to the surface of the base rod 280, springs 2910 are arranged between the arc-shaped plate 290 and the vertical plate 270, a fixed block 2920 is welded at the top of the arc-shaped baffle 250, a base rod 2930 is welded in the fixed block 2920, and an opening and closing plate 2940 is rotatably connected to the surface of the base rod 2930.

[0034] The feed falls through the feeding port 111 onto the long plate 230, and then slides from the long plate 230 to the inside of the feeding box 240. When the feed inside the feeding box 240 gradually increases, the arc-shaped plate 290 will squeeze the spring 2910 to shrink to one side at this time. After the feed is filled, the long shaft 220 is driven to rotate by starting the servo motor one 210, and the long shaft 220 drives the long plate 230 to make arc-shaped motion with the long shaft 220 as the center, so that the long plate 230 drives the three groups of feeding boxes 240 to rotate synchronously. When the feeding box 240 rotates by a certain angle, the feed inside the feeding box 240 will be scattered into the breeding net cage by inertia to achieve the purpose of feeding the fish population. At the same time, the two groups of arc-shaped grooves 251 arranged can make the feed spread to both sides when it is thrown out, which can effectively expand the range of throwing feed, and facilitate the fish to eat better. At the same time, it also effectively avoids the accumulation of feed during feeding. By arranging three groups of feeding boxes 240, different areas inside the breeding net cage can be fed by the same throwing radius during feeding. When the feed is thrown out, the feed inside the feeding box 240 will gradually decrease, and the arc-shaped plate 290 will gradually open under the action of the spring 2910, and the opening of the arc-shaped groove 251 will gradually become smaller. At the same time, the partition strip 260 can block the feed inside the feeding box 240 to a certain extent, so that the feed can be widely thrown horizontally and also vertically dropped into the breeding net cage during feeding, further improving the range of feed throwing. When the long plate 230 rotates to a certain angle, the feeding box 240 is inverted, and under the influence of gravity, the opening and closing plate 2940 rotates and opens from the top of the arc-shaped baffle 250 through the base rod two 2930, and then the residual feed inside the feeding box 240 is poured out, so that the residual feed is poured into the blind area position at the corner of the breeding net cage, avoiding the situation that the blind area position cannot feed the feed. The device can ensure that every fish in the fish population has the opportunity to eat the feed by widely feeding from near to far, avoid affecting the growth of some fish due to the lack of feed, thereby improving the uniformity of the growth of the fish population, effectively reducing the scattering and waste of feed in the water, reducing the breeding cost, and effectively avoiding the situation that a large number of fish accumulate and scramble for feed, leading to insufficient oxygen supply in the area, reducing the survival rate of the fish population, and even causing the water quality in the area to change, affecting the normal growth of the fish population.

[0035] Please refer to Figures 1 to 7 The inside of the feed box 110 is provided with a semicircular plate 120, and the feeding box 240 is arranged on the surface of the semicircular plate 120 to make arc-shaped track motion. The feed box 110 is provided with a feeding port 111 on one side, and three groups of feeding boxes 240 are arranged on the surface of the long plate 230. The feeding box 240 is in the shape of a spoon, and the partition strip 260 is provided with three groups. The heights of the three groups of partition strips 260 are arranged from high to low in sequence. One end of the spring 2910 is fixedly connected with the arc-shaped plate 290, and the other end of the spring 2910 is fixedly connected with the vertical plate 270.

[0036] By setting the feeding box 240 inside the semicircular plate 120, it can prevent the situation of scattering when adding feed, and by setting multiple groups of partition strips 260 from high to low, it can have a certain buffering effect on the feed, effectively preventing the feed from being thrown out to one area when throwing.

[0037] Please refer to Figure 2 , Figure 3 and Figure 8 , the rotating assembly 300 includes an L-shaped connecting plate 320 fixedly connected to the front end of the base 100, a servo motor 310 is installed on the L-shaped connecting plate 320, a sleeve 330 is fixedly connected to the output end of the servo motor 310, a reciprocating lead screw 340 is rotatably connected inside the sleeve 330, an extrusion plate 350 is welded to one end of the reciprocating lead screw 340 away from the sleeve 330, an oil groove 351 is formed in the base 100, an arc-shaped block groove 361 is formed in the base 100 on the side of the oil groove 351 away from the extrusion plate 350, a block 360 is slidably connected inside the arc-shaped block groove 361, a connecting plate 370 is welded to one side of the block 360, and a rotating disc 380 is fixedly connected to the side of the connecting plate 370 away from the block 360.

[0038] Start the servo motor 310 to drive the sleeve 330 to rotate, the sleeve 330 drives the reciprocating lead screw 340 to move reciprocally, the reciprocating lead screw 340 drives the extrusion plate 350 to compress the hydraulic oil inside the oil groove 351, under the action of pressure, the block 360 is pushed to move inside the arc-shaped block groove 361, the block 360 drives the rotating disc 380 to rotate synchronously through the connecting plate 370, the rotating disc 380 drives the feed bin 110 to rotate, when the first group of fish is finished feeding, the second feeding is carried out by rotating the feed bin 110, which can better expand the fan angle when feeding, and can cover a wider area, so that the fish can more evenly ingest the feed, thereby improving the feeding efficiency.

[0039] Please refer to Figure 3 , Figure 8 and Figure 9 , the extrusion plate 350 is slidably connected with the oil groove 351, the rotating disc 380 is rotatably connected with the base 100, and the top end of the rotating disc 380 is fixedly connected with the feed bin 110.

[0040] By rotatably connecting the rotating disc 380 with the base 100, the rotating disc 380 can drive the feed bin 110 to rotate synchronously when rotating.

[0041] When in use, the feed falls through the feeding port 111 to the long plate 230, and then slides from the long plate 230 to the inside of the feeding box 240. When the feed inside the feeding box 240 gradually increases, the arc-shaped plate 290 will squeeze the spring 2910 to shrink to one side at this time. After the feed is filled, the long shaft 220 is driven to rotate by starting the servo motor one 210, and the long plate 230 is driven to make arc-shaped motion with the long shaft 220 as the center, so that the long plate 230 drives the three groups of feeding boxes 240 to rotate synchronously. When the feeding box 240 rotates by a certain angle, the feed inside the feeding box 240 will be scattered into the breeding net cage by inertia to achieve the purpose of feeding the fish population. At the same time, the two groups of arc-shaped grooves 251 arranged can make the feed spread to the two side areas when it is thrown out, which can effectively expand the range of throwing feed, and facilitate the fish to eat better. At the same time, it also effectively avoids the accumulation of feed during feeding. By arranging three groups of feeding boxes 240, different areas inside the breeding net cage can be fed by the same throwing radius during feeding. When the feed is thrown out, the feed inside the feeding box 240 will gradually decrease, and the arc-shaped plate 290 will gradually open under the action of the spring 2910, thereby gradually reducing the opening of the arc-shaped groove 251. At the same time, the partition strip 260 can block the feed inside the feeding box 240 to a certain extent, so that the feed can be widely thrown horizontally while also falling vertically into the breeding net cage during feeding, further improving the range of feed throwing. When the long plate 230 rotates to a certain angle, the feeding box 240 is inverted, and the opening and closing plate 2940 is rotated and opened from the top of the arc-shaped baffle 250 by the base rod two 2930 under the influence of gravity, thereby making the residual feed in the feeding box 240 pour out, so that the residual feed is poured into the blind area position at the corner of the breeding net cage, avoiding the situation that the blind area position cannot feed the feed. The device can ensure that every fish in the fish population has the opportunity to eat the feed by widely feeding from near to far, avoid affecting the growth of some fish due to not being able to catch the feed, thereby improving the uniformity of the growth of the fish population, effectively reducing the scattering and waste of feed in the water, reducing the breeding cost, and effectively avoiding the situation that a large number of fish accumulate and rush for feed, leading to insufficient oxygen supply in the area, reducing the survival rate of the fish population, and even causing the water quality in the area to change, affecting the normal growth of the fish population. Starting the servo motor two 310 drives the sleeve 330 to rotate, the sleeve 330 drives the reciprocating screw rod 340 to move reciprocally, the reciprocating screw rod 340 drives the pressing plate 350 to compress the hydraulic oil in the oil groove 351, and the circular block 360 moves in the arc-shaped circular block groove 361 under the action of the pressure, the circular block 360 drives the rotating disc 380 to rotate synchronously through the connecting plate 370, and the rotating disc 380 drives the feed box 110 to rotate. After the first group of fish is fed, the feed box 110 is rotated for the second time to feed, which can better expand the fan angle during feeding and cover a wider area.The device makes fish population ingest feed more evenly, thus improving feeding efficiency.
