[0001] The invention relates to the technical field of automatic feeding, in particular to an automatic feeding system for marine aquaculture cages. Background Art

[0002] Deep-sea cages are mainly composed of frame systems, net bags, fixing systems and supporting facilities. The cages are lowered to a limited depth underwater by using the interaction of the fixed platform and the characteristics of the cages themselves. Since the wave intensity will decay exponentially with the increase of water depth, the wave intensity at the cages will also decrease exponentially at a certain depth, so as to achieve the purpose of resisting wind and waves. The appearance of this cage frame is a perfect circle, which is made of hot-melt welding of the main and auxiliary accessories such as the inner and outer ring main floating pipes, handrail column pipes, tees, positioning blocks, pins, etc. The materials are all made of new high-density polyethylene raw materials and anti-aging agents for one-time injection molding. The main floating pipe has a diameter of 250mm, the handrail has a diameter of 110mm, the column height is 80cm, the circumference of the box is 40 meters, the diameter is 13 meters, the aquaculture water can reach 2,000 cubic meters, the wave resistance is more than 7 meters, and it can resist typhoons above level 10.

[0003] Aquaculture is one of the important industries in my country's agriculture.

[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 cannot 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 Figure 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 includes 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 to a long shaft 220, the surface of the long shaft 220 is fixedly connected to a long plate 230, the surface of the long plate 230 is fixedly connected to three groups of feeding boxes 240, the top sides of the three groups of feeding boxes 240 are fixedly connected to arc baffles 250, and two groups of vertical plates 270 fixedly connected to the top of the feeding boxes 240 are arranged between the two groups of arc baffles 250. An arc groove 250 is opened between the arc baffle 250 and the vertical plate 270. 1. A straight groove 271 is provided between the two groups of vertical plates 270, a partition bar 260 fixedly connected to one side of the feeding box 240 is provided on one side of the arc baffle 250, a base rod 1 280 is fixedly connected inside the two groups of vertical plates 270, a curved plate 290 is rotatably connected on the surface of the base rod 1 280, a spring 2910 is provided between the curved plate 290 and the vertical plate 270, a fixed block 2920 is welded on the top of the arc baffle 250, a base rod 2930 is welded inside the fixed block 2920, and an opening and closing plate 2940 is rotatably connected on the surface of the base rod 2930.

[0034] The feed falls onto the long plate 230 through the feed inlet 111, 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 plate 290 will squeeze the spring 2910 to shrink to one side. After the feed is filled, the servo motor 210 is started to drive the long shaft 220 to rotate, and the long shaft 220 drives the long plate 230 to perform an arc motion with the long shaft 220 as the center of the circle, so that the long plate 230 drives the three groups of feeding boxes 240 to rotate synchronously. When the feeding box 240 rotates a certain angle, the feed inside the feeding box 240 will pass through the inertia motor 210. The feed can be thrown into the breeding cage to achieve the purpose of feeding the fish. At the same time, the two sets of arc grooves 251 can make the feed sprinkle to the two side areas when thrown, which can effectively expand the range of throwing feed, which is convenient for the fish to eat better and effectively avoid the accumulation of feed during feeding. By setting three sets of feeding boxes 240, the same throwing arc can be used to feed different areas of the breeding cage when feeding. When the feed is thrown, the feed inside the feeding box 240 will gradually decrease, and the arc plate 290 will gradually open under the reaction of the spring 2910, so that the feed can be thrown into the breeding cage. The opening of the arc groove 251 is gradually reduced, and the spacer 260 can have a certain blocking effect on the feed inside the feeding box 240. Therefore, when the feed is thrown, it can be widely thrown horizontally and can also fall into the breeding net cage vertically, further increasing the range of feed throwing. When the long board 230 rotates to a certain angle, the feeding box 240 is inverted. At this time, under the influence of gravity, the opening and closing plate 2940 is rotated and opened from the top of the arc baffle 250 through the base rod 2930, so that the residual feed in the feeding box 240 is poured out, and the residual feed is poured into the breeding net cage. The blind spot at the corner of the fish farm is located to avoid the situation where the fish cannot be fed in the blind spot. The device ensures that every fish in the fish school has the opportunity to eat the feed by feeding it extensively from near to far, avoiding the growth of some fish being affected due to the lack of feed, thereby improving the uniformity of the growth of the fish school, and effectively reducing the scattering and waste of feed in the water, reducing the breeding cost, and at the same time effectively avoiding the situation where a large number of fish gather to scramble for feed, resulting in insufficient oxygen supply in the area, reducing the survival rate of the fish school, and even causing changes in the water quality in the area in severe cases, affecting the normal growth of the fish school.

[0035] Please refer to Figures 1 to 7 A semicircular plate 120 is provided inside the feed box 110, and one side of the feeding box 240 is attached to the surface of the semicircular plate 120 and moves in an arc trajectory. A feeding port 111 is installed on one side of the feed box 110. Three groups of feeding boxes 240 are distributed in an array on the surface of the long plate 230. The feeding boxes 240 are spoon-shaped, and three groups of partition bars 260 are provided. The heights of the three groups of partition bars 260 are distributed in sequence from high to low. One end of the spring 2910 is fixedly connected to the arc plate 290, and the other end of the spring 2910 is fixedly connected to the vertical plate 270.

[0036] By arranging the feeding box 240 inside the semicircular plate 120, it is possible to prevent the feed from being scattered when added. By distributing multiple groups of partition bars 260 in sequence from high to low, a certain buffering effect can be achieved on the feed, effectively preventing the feed from being thrown into one area when being thrown.

[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 screw rod 340 is rotatably connected inside the sleeve 330, an extrusion plate 350 is welded to the end of the reciprocating screw rod 340 away from the sleeve 330, an oil groove 351 is opened inside the base 100, an arc-shaped round block groove 361 opened inside the base 100 is provided on the side of the oil groove 351 away from the extrusion plate 350, a round block 360 is slidably connected inside the arc-shaped round block groove 361, a connecting plate 370 is welded to one side of the round block 360, and a rotating disk 380 is fixedly connected to the side of the connecting plate 370 away from the round block 360.

[0038] The servo motor 310 is started to drive the sleeve 330 to rotate, and the sleeve 330 drives the reciprocating screw 340 to reciprocate, so that the reciprocating screw 340 drives the extrusion plate 350 to compress the hydraulic oil in the oil groove 351, and the round block 360 is pushed to move in the arc-shaped round block groove 361 under the action of pressure. The round block 360 drives the rotating disk 380 to rotate synchronously through the connecting plate 370, so that the rotating disk 380 drives the feed box 110 to rotate. After the first pair of fish is fed, the second feeding is performed by rotating the feed box 110, which can better expand the fan-shaped angle during feeding and cover a wider area, so that the fish can ingest the feed more evenly, thereby improving the feeding efficiency.

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

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

[0041] When in use, the feed falls onto the long board 230 through the feed inlet 111, and then slides from the long board 230 to the inside of the feeding box 240. When the feed in the feeding box 240 gradually increases, the arc plate 290 will squeeze the spring 2910 to shrink to one side. After the feed is filled, the servo motor 210 is started to drive the long shaft 220 to rotate, and the long shaft 220 drives the long board 230 to perform an arc motion with the long shaft 220 as the center, so that the long board 230 drives the three groups of feeding boxes 240 to rotate synchronously. When the feeding box 240 rotates a certain angle, the feed in the feeding box 240 will be scattered into the inside of the breeding net cage by inertia to achieve the purpose of feeding the fish school. At the same time, the two groups of arc grooves 251 can make the feed to the two sides when thrown out. The feed can be spread out in a wide range, which can effectively expand the range of scattering feed, making it easier for fish to eat, and at the same time effectively avoiding the accumulation of feed during feeding. By setting up three groups of feeding boxes 240, feeding in different areas inside the breeding cage can be achieved through the same throwing arc when feeding. When the feed is thrown out, the feed inside the feeding box 240 will gradually decrease, and the arc plate 290 will gradually open under the reaction of the spring 2910, so that the opening of the arc groove 251 will gradually become smaller. At the same time, the partition bar 260 can have a certain blocking effect on the feed inside the feeding box 240. Therefore, when feeding, the feed can be widely thrown horizontally and can also fall into the breeding cage vertically, further increasing the range of feed throwing. When it is turned to a certain angle, the feeding box 240 is inverted. At this time, under the influence of gravity, the opening and closing plate 2940 is rotated and opened from the top of the arc-shaped baffle 250 through the base rod 2930, so that the residual feed in the feeding box 240 is poured out, and the residual feed is poured into the blind spot position at the corner of the breeding net cage, thereby avoiding the situation that the blind spot position cannot be fed with feed. The device can ensure that every fish in the fish school has the opportunity to eat feed by feeding widely from near to far, avoiding that some fish are unable to grab feed and affecting their growth, thereby improving the uniformity of the growth of the fish school, and effectively reducing the scattering and waste of feed in the water, reducing the breeding cost, and at the same time effectively avoiding the situation that a large number of fish schools accumulate and scramble for feed, resulting in insufficient oxygen supply in the area. The survival rate of the fish school is reduced. In severe cases, it may even cause changes in the water quality of the area, affecting the normal growth of the fish school. The servo motor 310 is started to drive the sleeve 330 to rotate. The sleeve 330 drives the reciprocating screw 340 to move back and forth, so that the reciprocating screw 340 drives the extrusion plate 350 to compress the hydraulic oil in the oil groove 351. Under the action of pressure, the round block 360 is pushed to move inside the arc-shaped round block groove 361. The round block 360 drives the rotating disk 380 to rotate synchronously through the connecting plate 370, so that the rotating disk 380 drives the feed box 110 to rotate. After the first pair of fish is fed, the second feeding is carried out by rotating the feed box 110, which can better expand the fan-shaped angle when feeding and cover a wider area.The fish can ingest feed more evenly, thereby improving feeding efficiency. The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology.
