Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, and more particularly to an intelligent feeding system for breeding fish in modern aquaculture. Background Art

[0002] Nowadays, in the field of aquaculture, feeding machines are becoming the second most popular breeding equipment after aerators. The use of feeding machines can not only reduce manual input, but also its characteristics of timing, quantitative and multiple feeding combined with scientific feeding mode can effectively reduce the feed ratio and significantly improve efficiency. At present, the traditional centrifugal feeding machine used for aquaculture has a low height from the water surface due to the feeding device located at the bottom of the whole machine, and the flight time of the feed is short, which is not conducive to feeding the feed to a larger range. In order to expand the feed delivery range, the rotation speed is usually increased and a more powerful feeding motor is used to compensate for the problem of the feeding range. As a result, the energy consumption is increased and the effect is not good, and the feed breakage rate is increased. In addition, the design of the traditional bottom-mounted feeding device cannot directly increase the feeding range by increasing the height of the feeding device. While increasing the height of the feeding device, the feed needs to be transported from low to high, and the height of the feeding device cannot be adjusted at any time, which is not conducive to feeding the feed to different ranges. Therefore, it is necessary to provide a modern intelligent feeding system for breeding fish in aquaculture to solve the problems raised in the above background technology. Summary of the invention

DETAILED DESCRIPTION

[0053] See also Figure 1 to Figure 7 In an embodiment of the present invention, a modern aquaculture fish breeding intelligent feeding system comprises:

[0054] A suspended body 1 is movably arranged on the water surface;

[0055] A driving connector 2 is fixed on the top of the suspension body 1, and a driving motor is provided inside the driving connector 2;

[0056] A material storage device 3 is fixed on the top of the driving connecting member 2;

[0057] A feeding device 4 is arranged at the center of the storage device 3, and the bottom of the feeding device 4 is connected to the driving motor;

[0058] The adjusting device 5 is slidably arranged on the outside of the feeding device 4 and is slidably connected to the storage device 3;

[0059] A plurality of feeding devices 6 are provided in an annular distribution and fixed on the adjusting device 5;

[0060] The protective device 7 is fixedly connected to the storage device 3 at the bottom and connected to the feeding device 4 at the top.

[0061] In this embodiment, the storage device 3 includes:

[0062] The storage disc 31 has its bottom fixed on the top of the driving connector 2;

[0063] A plurality of storage cylinders 32 are provided in an annular arrangement and fixed on the top of the storage disc 31;

[0064] A plurality of connecting arc surfaces 33 are provided in an annular distribution, are spaced apart from the storage cylinders 32, and are fixed on the top of the storage disc 31, and the two sides of the connecting arc surfaces 33 are connected to the adjacent storage cylinders 32;

[0065] The central circular ring 34 is arranged at the top center of the storage disc 31 , the inner ring is fixedly connected to the feeding device 4 , and the outer ring is fixedly connected to the connecting arc surface 33 .

[0066] That is to say, under the joint action of the storage cylinder 32 and the storage disc 31, the feed is stored, and the multiple storage cylinders 32 are distributed at intervals, so that the adjustment device 5 can adjust the height and angle of the feeding device 6 without obstacles, so that the feeding range is wider and the distance is farther, which is convenient for accurate feeding. Under the action of the connecting arc surface 33 and the center ring 34, the top of the storage disc 31 is sealed. As the feed is consumed, the feed inside the storage cylinder 32 falls into the storage disc 31. Under the action of the feeding device 4, the feed is transported upward to the adjustment device 5, and then thrown into a predetermined area through the feeding device 6.

[0067] In this embodiment, the feeding device 4 includes:

[0068] The delivery pipe 41 is arranged at the top center of the storage disc 31, and the bottom of the delivery pipe 41 is fixedly connected to the inner ring of the center ring 34;

[0069] A conveying screw 42 is rotatably disposed in the conveying pipe 41, and the bottom of the conveying screw 42 passes through the storage disc 31 and is fixedly connected to the driving motor, and the top is rotatably connected to the protective device 7;

[0070] The positioning block 43 is fixed on the top of the protective device 7 and is rotatably connected to the conveying screw 42 .

[0071] That is to say, driven by the driving motor, the conveying screw 42 rotates in the conveying pipe 41, and the feed inside the storage disc 31 is conveyed upward to the feeding device 6 on the adjusting device 5 through the conveying screw 42, so that the feed is continuously conveyed.

[0072] In this embodiment, the adjusting device 5 comprises:

[0073] A lifting pipe 51 is slidably disposed on the outer wall of the delivery pipe 41;

[0074] A distribution turntable 52 is rotatably disposed at the top pipe opening of the lifting pipe 51;

[0075] A plurality of guide blocks 53 are provided in an annular distribution and are disposed on the distribution turntable 52, and the guide blocks 53 correspond to the storage cylinders 32;

[0076] An adjustment assembly 54 is disposed on the outer wall of the lifting tube 51;

[0077] A plurality of spacers 55 are provided in an annular distribution and are arranged corresponding to the storage cylinders 32 , and the top of the spacers 55 is rotatably connected to the distribution turntable 52 and fixedly connected to the guide block 53 .

[0078] That is to say, when the lifting tube 51 moves up and down on the conveying tube 41, the adjusting component 54 is driven to move up and down, and then the feeding device 6 is driven to move, and the height of the feeding device 6 is adjusted. At the same time, the spacer 55 follows the lifting tube 51 to move up and down under the drive of the guide block 53, that is, the spacer 55 and the feeding device 6 on the adjusting component 54 maintain a relative position, and the two sides of the feeding device 6 are restricted by the spacer 55. When the feed is placed on the feeding device 6, it is scattered, and after the spacer 55 moves up, the storage cylinder 32, the connecting arc surface 33 and the center ring 34 close the storage disc 31 to maintain the normal conveying of the feed. When the feed is conveyed upward through the feeding device 4 and output from the pipe mouth of the lifting tube 51, the feed falls on the distribution turntable 52. Under the continuous rotation of the distribution turntable 52, the feed moves around, and under the joint action of the guide block 53 and the spacer 55, the feed enters the feeding device 6 between the spacers 55.

[0079] In this embodiment, the adjustment component 54 includes:

[0080] A fixing ring 541 is fixed to the upper part of the lifting tube 51 and is located below the distribution turntable 52;

[0081] A movable ring 542 is slidably disposed at the lower portion of the lifting tube 51;

[0082] A plurality of rotating connecting rods 543 are provided in an annular distribution and are spaced apart from the spacers 55 , and the top ends of the rotating connecting rods 543 are hinged to the fixing ring 541 ;

[0083] An adjusting link 544 is provided corresponding to the rotating link 543, and two ends of the adjusting link 544 are respectively hinged to the moving ring 542 and the rotating link 543;

[0084] There are a plurality of limiting arc surfaces 545 distributed in an annular manner, corresponding to the connecting arc surface 33 , and arranged above the connecting arc surface 33 to connect the spacers 55 on both sides.

[0085] That is to say, under the action of the limiting arc surface 545, multiple spacers 55 are connected, and the minimum angle of rotation of the adjusting link 544 is limited. When the moving ring 542 moves upward on the lifting tube 51, the adjusting link 544 drives the rotating link 543 to rotate to a position away from the center of the lifting tube 51, and at the same time drives the feeding device 6 to move to a range away from the lifting tube 51, so as to deliver feed to a distant water area; when the moving ring 542 moves downward on the lifting tube 51, the adjusting link 544 drives the rotating link 543 to rotate to a position close to the center of the lifting tube 51, and at the same time drives the feeding device 6 to move to a range close to the lifting tube 51, so as to deliver feed to a nearby water area, and under the restriction of the limiting arc surface 545, the rotation angle of the rotating link 543 is limited to prevent multiple rotating links 543 from concentrating the feeding device 6 around the lifting tube 51, resulting in a small feeding range and excessive feeding density.

[0086] In this embodiment, the spacer 55 includes:

[0087] The vertical arc surface 551 is disposed between the rotating connecting rods 543 and is located outside the fixed ring 541 and the movable ring 542;

[0088] Two vertical plates 552 are symmetrically arranged and fixed on both sides of the vertical arc surface 551 , and the vertical plates 552 are arranged between the rotating connecting rod 543 and the storage cylinder 32 .

[0089] That is to say, when the feed is transported upward through the feeding device 4 and output from the pipe mouth of the lifting tube 51, the feed falls onto the distribution turntable 52. With the continuous rotation of the distribution turntable 52, the feed moves around, and under the action of the vertical arc surface 551, the guide block 53 maintains its position unchanged. Then, under the guidance of the guide block 53, the feed enters between the vertical plates 552 and falls onto the feeding device 6 on the rotating connecting rod 543, and is delivered through the feeding device 6.

[0090] In this embodiment, the feeding device 6 comprises:

[0091] The conveyor belt 61 is fixed above the rotating connecting rod 543, and the input end of the conveyor belt 61 corresponds to the distribution turntable 52;

[0092] The rotating impeller 62 is rotatably disposed at one end of the rotating connecting rod 543 . The rotating impeller 62 is located at the output end of the conveyor belt 61 , and the conveyor belt 61 and the rotating impeller 62 operate independently.

[0093] That is to say, when the feed enters between the vertical plates 552 under the action of the distribution turntable 52 and the guide block 53, the feed falls on the conveyor belt 61 on the rotating connecting rod 543, and is transported to the rotating impeller 62 driven by the conveyor belt 61. The feed is thrown out under the rotation of the rotating impeller 62. The throwing distance of the feed can be controlled by controlling the rotation speed of the rotating impeller 62. The faster the rotation speed, the farther the feed is thrown. It should be noted that the rotation speed of the rotating impeller 62 should ensure that the feed can fall on the rotating impeller 62 to prevent the rotating impeller 62 from rotating too fast and directly breaking the fallen feed.

[0094] In this embodiment, the protection device 7 includes:

[0095] A connecting bottom plate 71 is provided with a plurality of connecting bottom plates 71 distributed in an annular manner, corresponding to the storage cylinder 32, and fixed at the connection between the storage disc 31 and the storage cylinder 32;

[0096] The arc protection plate 72 is provided corresponding to the connection bottom plate 71, fixed to the outer side of the connection bottom plate 71, and slidably connected to the spacer 55;

[0097] A top plate 73 is fixed on the top of the arc protection plate 72, and the top plate 73 is fixed on the top of the storage column 32 and carries the positioning block 43;

[0098] The protective member 74 is arranged corresponding to the spacer 55 , fixed to the bottom of the top plate 73 , and arranged between the spacer 55 and the storage column 32 .

[0099] That is to say, under the action of the connecting bottom plate 71 and the protective arc plate 72, the storage column 32 and the vertical plate 552 are protected, and under the action of the top plate 73, the positioning block 43 is supported, and a feed port is provided on the top plate 73, corresponding to the storage column 32. Under the action of the protective member 74, the spacer 55 and the storage column 32 are protected to prevent the spacer 55 from moving up and down multiple times and causing damage to the storage column 32, thereby extending the service life of the storage column 32. The protective member 74 can also guide the feed to the feeding device 6 between the spacers 55 together with the spacers 55.

[0100] During specific implementation, the suspension body 1 first drives the feeding device to move on the water surface, selects a suitable feeding location, and then the suspension body 1 is suspended, and then moves up and down on the conveying pipe 41 through the lifting tube 51, driving the adjustment component 54 to move up and down, thereby driving the feeding device 6 to move, and adjusting the height of the feeding device 6, and then adjusting the delivery range by moving the moving ring 542 on the lifting tube 51. When the moving ring 542 moves upward on the lifting tube 51, the rotating connecting rod 543 is driven to rotate to a position away from the center of the lifting tube 51 through the adjusting connecting rod 544, and at the same time, the feeding device 6 is driven to move to a range away from the lifting tube 51, so that feed can be delivered to a distant water area; when the moving ring 542 moves downward on the lifting tube 51, the connecting rod 54 is adjusted to move upward. The rotating connecting rod 543 is driven to rotate toward the position close to the center of the lifting tube 51, and the feeding device 6 is driven to move toward the range close to the lifting tube 51, so that feed can be delivered to the nearby water area. Then, driven by the conveying screw 42, the feed is conveyed upward through the conveying tube 41 and output from the pipe mouth of the lifting tube 51, and the feed falls on the distribution turntable 52. Under the continuous rotation of the distribution turntable 52, the feed moves to the surroundings, and under the joint action of the guide block 53 and the spacer 55, the feed enters the feeding device 6 on the rotating connecting rod 543 between the spacers 55, that is, the feed falls on the conveyor belt 61 on the rotating connecting rod 543, and is conveyed to the rotating impeller 62 under the drive of the conveyor belt 61. Under the rotation of the rotating impeller 62, the feed is thrown out, and the feed is delivered to the fish school in a predetermined area.

[0101] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
