Description

Technical Field

[0001] This invention relates to the field of fish fry breeding and aquaculture technology, specifically to a feeding device for breeding and aquaculture of schizothorax fry. Background Technology

[0002] Schizothorax is a cold-water cyprinid fish unique to the plateau waters of my country, possessing both ecological and economic value. Its tender flesh and rich nutrition make it an important species for specialty aquaculture. Furthermore, some Schizothorax species are key species in aquatic ecosystems; artificial breeding and cultivation not only meet market demand but also effectively protect wild populations, contributing to the maintenance of aquatic biodiversity in the plateau region. In recent years, with the gradual breakthroughs in artificial breeding technology for Schizothorax, large-scale fry cultivation has become a core link in industrial development and species protection. Feeding, as a crucial process in fry breeding and cultivation, directly determines the survival rate, growth uniformity, and germplasm quality of the fry, and is one of the core factors restricting the large-scale breeding and cultivation of Schizothorax. Schizothorax fry exhibit unique physiological and feeding characteristics, significantly different from conventionally farmed freshwater fish: firstly, Schizothorax has a long post-embryonic development period and weak feeding ability; secondly, as a cold-water fish, the fry stage has a slow metabolic rate and a gradual feeding rhythm.

[0003] Chinese patent CN111990309B discloses a feeding device, particularly an automatic fish feed dispensing device. The technical problem this invention aims to solve is to provide an automatic fish feed dispensing device capable of simultaneously dispensing feed to locations both far from and near the device. An automatic fish feed dispensing device includes: a support frame; a discharging component mounted on the support frame; a feeding assembly mounted between the discharging component and the support frame; and a feed conveying and ejecting assembly mounted on the feeding assembly. This invention allows for intermittent feeding of fish feed through the cooperation of the feeding and discharging components. During the feeding process, the fish feed is shaken to prevent blockage or agglomeration. Furthermore, the invention can scatter some fish feed during the feeding process, increasing the area of ​​feed falling into the water and preventing eutrophication in certain areas. However, this device cannot adjust the feeding amount or reduce feed residue, and the accuracy of the feeding quantity needs improvement. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides: a feeding device for breeding and raising fry of Schizothorax fish, comprising: The frame has a support rod fixedly connected to its outer side. A buoyancy ball is fixedly connected to the end of the support rod away from the frame via a bracket. A storage box is fixedly connected to the top of the frame. A filling port is opened on the top of the storage box. A discharge frame is connected to the bottom of the storage box. A feeding device, the top of which is fixedly connected to the outside of the frame; A diffusion device, wherein the outer side of the diffusion device is fixedly connected to the outer side of the frame via a bracket; The support rods are provided in multiple sets, and the multiple sets of support rods are evenly distributed on the outside of the frame; The feeding device includes: The feeding roller has two ends rotatably connected to limit slides via bearings. A suspension plate is slidably connected inside the limit slides via a slider. A first drive motor is fixedly connected to one side of the suspension plate via a bracket. The output end of the first drive motor is fixedly connected to the input end of a belt drive assembly. The output end of the belt drive assembly is fixedly connected to a rotating shaft. A side plate is fixedly connected to one side of the suspension plate via a bracket. The input and output ends of the belt drive assembly are rotatably connected to the discharge frame and the side plate respectively via rotating brackets. The feeding roller has a feeding trough, and extension grooves are formed on both sides of the inner wall of the feeding trough. A groove is formed at the bottom of the feeding trough. The feeding roller drives the feeding trough and extension grooves to move away from the discharge frame and continue moving. At this time, the feed inside the feeding trough and extension grooves gradually falls onto the water surface under its own gravity, thus distributing a fixed amount of feed into the breeding tank. Simultaneously, the device floats on the water surface, allowing it to feed at any location in the breeding tank, even to any corner.

[0005] Preferably, the top of the suspension plate is fixedly connected to the outside of the frame, the rotating shaft passes through the feeding roller and is fixedly connected to the feeding roller, multiple sets of feeding troughs are provided, and the feeding roller is located directly below the discharge frame and is slidably connected to the bottom of the discharge frame.

[0006] Preferably, the feeding device includes a scraping device, the bottom of which is fixedly connected to the bottom of the inner wall of the groove.

[0007] Preferably, both sides of the feeding frame are fixedly connected to arc-shaped baffles. The outer side of the arc-shaped baffles is provided with a feeding hole. A portion of the feed in the feeding trough and the extension trough is discharged from the feeding hole. As the feeding roller continues to rotate, the feeding roller drives the feeding trough and the extension trough to move away from the arc-shaped baffles. After moving away, the feed in the feeding trough and the extension trough is then scattered onto the water surface. This allows for small-volume, multiple feedings, improving the feeding rate, ensuring uniform growth of fish fry, and reducing uneaten feed at the bottom. The outer side of the arc-shaped baffles is fixedly connected to a directional rod via a bracket. A sponge sleeve is fitted and fixedly connected to the outer side of the directional rod.

[0008] Preferably, multiple sets of discharge holes are provided, and the multiple sets of discharge holes are evenly distributed on the outer side of the arc-shaped baffle. Each discharge hole corresponds to a feeding trough, and the inner side of the arc-shaped baffle is slidably connected to the outer side of the feeding roller.

[0009] Preferably, the scraping device includes an electric push rod, the movable end of which is fixedly connected to an adjusting plate. As the adjusting plate moves, the space inside the feeding trough that can hold feed decreases, thereby adjusting the feeding amount. The adjusting plate can push out the feed adhering to the inner wall of the feeding trough. A second drive motor is fixedly connected to the side of the adjusting plate away from the electric push rod. A rotating disk is fixedly connected to the output end of the second drive motor. A limit plate is fixedly connected to the outer side of the rotating disk. A flexible scraper is fixedly connected through and to one side of the limit plate. The second drive motor drives the rotating disk to rotate, and the rotating disk drives the flexible scraper through the limit plate to scrape off the feed accumulated on the adjusting plate, effectively reducing feed residue and improving the accuracy of the feeding amount.

[0010] Preferably, the bottom of the electric push rod is fixedly connected to the bottom of the inner wall of the groove, and the outer side of the adjusting plate is slidably connected to the inner wall of the feeding trough.

[0011] Preferably, the diffusion device includes a diversion pipe, both ends of which are connected to arc-shaped pipes. A first exhaust port is symmetrically opened on one side of the arc-shaped pipe, and a second exhaust port is opened on the side of the arc-shaped pipe located at the first exhaust port. An extension frame is fixedly connected to the outside of the arc-shaped pipe, and an air pump is connected to the outside of the diversion pipe. The gas discharged from the first exhaust port can blow the feed discharged from two sets of discharge holes to the side, and the gas discharged from the second exhaust port can blow the feed discharged from two sets of feeding troughs to the side, thereby expanding the feed dispensing range.

[0012] Preferably, multiple sets of the second exhaust vents are provided, the top of the extension frame is fixedly connected to the outside of the frame, and the outside of the air pump is fixedly connected to the outside of the frame through a bracket.

[0013] This invention provides a feeding device for breeding and raising fry of Schizothorax fish. It has the following beneficial effects: 1. The feeding device for breeding and raising fry of Schizothorax fish, through the setting of feeding device and buoyancy ball, the feeding roller drives the feeding trough and extension trough to move away from the inside of the discharge frame and continue to move. At this time, the feed inside the feeding trough and extension trough is gradually scattered onto the water surface by its own gravity, so that a certain amount of feed can be scattered into the breeding pond. At the same time, the device floats on the water surface, so that the device can feed at any position in the breeding pond and can scatter the feed to any corner of the breeding pond.

[0014] 2. The feeding device for breeding and raising fry of the schizothorax fish, through the installation of a scraper, reduces the space inside the feeding trough that can hold feed as the adjusting plate moves, thus adjusting the feeding amount. As the adjusting plate moves, it can push out the feed adhering to the inner wall of the feeding trough. The second drive motor drives the rotating disc to rotate, and the rotating disc drives the flexible scraper through the limit plate to scrape off the feed accumulated on the adjusting plate, effectively reducing feed residue and improving the accuracy of feeding.

[0015] 3. The feeding device for breeding and raising fry of the schizothorax fish, through the setting of the arc-shaped baffle and the discharge hole, allows some of the feed inside the feeding trough and the extension trough to be discharged from the discharge hole. As the feeding roller continues to rotate, the feeding roller drives the feeding trough and the extension trough to move away from the arc-shaped baffle. After moving away, the feed inside the feeding trough and the extension trough is then scattered onto the water surface. This allows for small and frequent discharge of feed, improving the feeding rate, ensuring uniform growth of the fry, and reducing uneaten feed sinking to the bottom.

[0016] 4. The feeding device for breeding and raising fry of the schizothorax fish, through the installation of a diffusion device, allows the gas discharged from the first exhaust port to blow the feed discharged from two sets of feed holes to the side, and the gas discharged from the second exhaust port to blow the feed discharged from two sets of feeding troughs to the side, thereby expanding the feed distribution range.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] For the first embodiment, please refer to... Figures 1-8 The present invention provides a technical solution: a feeding device for breeding and raising fry of Schizothorax fish, comprising: The frame 1 has a support rod 2 fixedly connected to its outer side.

Multiple sets of support rods 2 are provided, and the multiple sets of support rods 2 are evenly distributed on the outside of the frame 1; The feeding device 7 includes: The feeding roller 71 has two ends rotatably connected to the limiting slide rail 72 via bearings. The limiting slide rail 72 has a suspension plate 73 slidably connected to it via a slider. A first drive motor 74 is fixedly connected to one side of the suspension plate 73 via a bracket. The output end of the first drive motor 74 is fixedly connected to the input end of the belt drive assembly 75. The output end of the belt drive assembly 75 is fixedly connected to the rotating shaft 76. A side plate 77 is fixedly connected to one side of the suspension plate 73 via a bracket. The input end and output end of the belt drive assembly 75 are rotatably connected to the discharge frame 6 and the side plate 77 respectively via rotating brackets. The feeding roller 71 has a feeding groove 78. The inner wall of the feeding groove 78 has extension grooves 710 on both sides. The bottom of the feeding groove 78 has a groove 711.

[0021] The top of the suspension plate 73 is fixedly connected to the outside of the frame 1. The rotating shaft 76 passes through the feeding roller 71 and is fixedly connected to the feeding roller 71. Multiple sets of feeding troughs are provided. The feeding roller 71 is located directly below the discharge frame 6 and is slidably connected to the bottom of the discharge frame 6.

[0022] The feeding device 7 includes a scraper 79, the bottom of which is fixedly connected to the bottom of the inner wall of the groove 711.

[0023] Both sides of the discharge frame 6 are fixedly connected with arc-shaped baffles 9. The outer side of the arc-shaped baffles 9 is provided with discharge holes 10. The outer side of the arc-shaped baffles 9 is fixedly connected with a directional rod 11 through a bracket. A sponge sleeve 12 is sleeved and fixedly connected to the outer side of the directional rod 11.

[0024] Multiple sets of discharge holes 10 are provided, and the multiple sets of discharge holes 10 are evenly distributed on the outer side of the arc-shaped baffle 9. The discharge holes 10 correspond one-to-one with the feeding trough 78. The inner side of the arc-shaped baffle 9 is slidably connected to the outer side of the feeding roller 71.

[0025] The scraping device 79 includes an electric push rod 791. An adjusting plate 792 is fixedly connected to the movable end of the electric push rod 791. A second drive motor 793 is fixedly connected to the side of the adjusting plate 792 away from the electric push rod 791. A rotating disk 794 is fixedly connected to the output end of the second drive motor 793. A limiting plate 795 is fixedly connected to the outer side of the rotating disk 794. A flexible scraper 796 is fixedly connected through one side of the limiting plate 795.

[0026] The bottom of the electric push rod 791 is fixedly connected to the bottom of the inner wall of the groove 711, and the outer side of the adjusting plate 792 is slidably connected to the inner wall of the feeding trough 78.

[0027] In use, the buoyancy ball 3 uses its own buoyancy to drive the frame 1 and the storage box 4 to float on the surface of the breeding pond. When it is necessary to feed into the breeding pond, the first drive motor 74 is turned on. The output end of the first drive motor 74 drives the rotating shaft 76 to rotate through the belt drive assembly 75. The rotating shaft 76 drives the feeding roller 71 to rotate. When the feeding roller 71 rotates, it gradually moves the feeding trough 78, which was originally inside the discharge frame 6, out of the discharge frame 6. The feeding trough 78 and the extension trough 710, which were originally inside the discharge frame 6, accumulate a certain amount of feed. As the feeding roller 71 rotates, it drives the feeding trough 78 and the extension trough 710 to move away from the discharge frame 6 and continue to move. At this time, the feed in the feeding trough 78 and the extension trough 710 gradually falls to the water surface by its own gravity, so that a certain amount of feed can be fed into the breeding pond. At the same time, the device floats on the water surface, so that the device can feed at any position in the breeding pond and can feed any corner of the breeding pond.

[0028] When the electric push rod 791 is activated, its movable end extends and pushes the adjusting plate 792 to move along the inner wall of the feeding trough 78. As the adjusting plate 792 moves, the space inside the feeding trough 78 that can hold feed decreases, allowing for adjustment of the feeding amount. After feeding, the electric push rod 791 is activated again, which drives the adjusting plate 792 to continue moving along the inner wall of the feeding trough 78. As the adjusting plate 792 moves, it pushes out the feed adhering to the inner wall of the feeding trough 78. At this time, the second drive motor 793 is activated, which drives the rotating disk 794 to rotate. The rotating disk 794 drives the flexible scraper 796 to rotate through the limiting plate 795. The rotating flexible scraper 796 can scrape off the feed accumulated on the adjusting plate 792, effectively reducing feed residue and improving the accuracy of the feeding amount.

[0029] When the feeding roller 71 moves the feeding trough 78 and the extension trough 710 away from the inside of the discharge frame 6 and to the discharge hole 10, some of the feed inside the feeding trough 78 and the extension trough 710 is discharged from the discharge hole 10. As the feeding roller 71 continues to rotate, it moves the feeding trough 78 and the extension trough 710 away from the arc-shaped baffle 9. After they are moved away, the feed inside the feeding trough 78 and the extension trough 710 is then scattered onto the water surface. This allows for small-volume, multiple discharges, improving the feeding rate, ensuring uniform growth of the fish fry, and reducing uneaten feed at the bottom.

[0030] Second embodiment, please refer to Figures 1-9The present invention provides a technical solution: Based on the first embodiment, the diffusion device 8 includes a diversion pipe 81, both ends of the diversion pipe 81 are connected to an arc-shaped pipe 82, a first exhaust port 83 is symmetrically opened on one side of the arc-shaped pipe 82, a second exhaust port 84 is opened on one side of the arc-shaped pipe 82 located at the first exhaust port 83, an extension frame 85 is fixedly connected to the outside of the arc-shaped pipe 82, and an air pump 86 is connected to the outside of the diversion pipe 81.

[0031] Multiple sets of second-row air vents 84 are provided. The top of the extension frame 85 is fixedly connected to the outside of the frame 1, and the outside of the air pump 86 is fixedly connected to the outside of the frame 1 through a bracket.

[0032] When in use, turn on the air pump 86. The air pump 86 draws the external gas into the diversion pipe 81, and then discharges it into the arc-shaped pipe 82 through the diversion pipe 81. The gas is finally discharged from the first exhaust port 83 and the second exhaust port 84. The gas discharged from the first exhaust port 83 can blow the feed discharged from the two sets of discharge holes 10 to the side, and the gas discharged from the second exhaust port 84 can blow the feed discharged from the two sets of feeding troughs 78 to the side, thereby expanding the feed distribution range.

[0033] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
