Abstract

This invention relates to the field of fish farming technology, specifically to a fish feeding device, comprising a feed storage bin and a mounting bracket installed on the outer wall of the feed storage bin. A discharge pipe is located at the bottom of the feed storage bin, and a first opening / closing assembly, a second opening / closing assembly, and a feed dispensing assembly are sequentially installed inside the discharge pipe from top to bottom. This invention utilizes the linkage design of the first and second opening / closing assemblies. The rotating disc plate rotates, and a rotating long plate is driven to rotate via a first linkage rod. The rotation of the long plate, through a hinged rod, causes the opening / closing plate to slide symmetrically within the discharge pipe, achieving double-layer closure and opening of the discharge pipe. This effectively prevents moisture from contacting the fish feed inside the feed storage bin, preventing the fish feed from becoming damp and clumping.

Description

Technical Field

[0001] This invention relates to the field of fish farming technology, specifically to a fish farming feeding device. Background Technology

[0002] Fish farming, also known as aquaculture, fish farming, and fish industry, is important for maintaining food supplies, fishing, and expanding fishing areas. Through fish farming, many species have been successfully introduced to new areas. There are various ways to feed fish, including natural feeds, artificial feeds, by-products such as chili meal, and automatic feeders.

[0003] Patent application CN202610007947.8 discloses an automatic fish tank feeder, including a shell, a storage chamber, a delivery pipe, a delivery pump, valve one, valve two, and valve three. The shell includes a fixed cylinder and a sealing plate detachably connected to the upper opening of the fixed cylinder. The storage chamber is arranged inside the fixed cylinder and is used to store fish food. The delivery pipe connects the shell and the storage chamber. The outlet at the first end of the delivery pipe passes through the shell and connects to valve one. The outlet is inclined upward. The inlet at the upper side of the second end of the delivery pipe passes through the lower side of the storage chamber and connects to valve two. The outlet at the lower side of the second end of the delivery pipe is connected to valve three. The delivery pump is arranged outside the fixed cylinder and in contact with the water in the fish tank. The output end of the delivery pump is connected to the delivery pipe and is used to pump water from the fish tank into the delivery pipe, so that the fish food in the delivery pipe is transported into the fish tank in a parabolic manner under the action of water flow, prolonging the slow sinking time of the fish food in the water.

[0004] Current mainstream solutions generally use a single-layer structure to block the feed outlet. However, the fish food storage in the feeding device is located above the water body, which is in close contact with water vapor and is very prone to getting damp. This can prevent the fish food from falling and thus render the device unusable.

[0005] In view of this, we propose a fish farming feeding device. Summary of the Invention

[0006] In order to overcome the defects in the prior art, the present invention aims to provide a fish farming feeding device, which uses a linkage mechanism between the first opening and closing component and the second opening and closing component to double-close the discharge pipe by means of a material blocking circular plate and an opening and closing plate, so as to prevent the fish feed in the storage tank from getting damp and solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides a fish farming feeding device, including a storage tank and a mounting frame installed on the outer wall of the storage tank. The bottom end of the storage tank is provided with a discharge pipe, and a first opening and closing component, a second opening and closing component, and a dispersing component are installed sequentially from top to bottom inside the discharge pipe. The first opening and closing assembly includes a material blocking disc rotatably connected to the discharge pipe and two first bevel gears respectively fixed on both sides of the rotating shaft of the material blocking disc; The second opening and closing assembly includes a set of opening and closing plates symmetrically slidably inserted into both sides of the discharge pipe, two rotating long plates rotatably connected to both sides of the side wall of the discharge pipe, and two first linkage rods rotatably connected to the inner sides of the side wall of the discharge pipe; a second bevel gear is coaxially welded and fixed at the center of the inner side wall of the rotating long plate, and hinge rods are respectively hinged between the upper and lower ends of the outer side wall of the rotating long plate and the opening and closing plates on both sides; the rotation of the first bevel gear drives the rotating long plate to rotate through the first linkage rods. The bulk material assembly includes a rotating ring rotatably connected to the inner wall of the discharge pipe, a connecting frame welded and fixed to the bottom end of the rotating ring, a bulk material tray welded and fixed to the bottom end of the connecting frame, and two second linkage rods rotatably connected to the inner sides of the side wall of the discharge pipe; the rotating plate rotates to drive the rotating ring to rotate via the second linkage rods.

[0008] This design takes into account the need for precise feeding and the requirement for dry fish food preservation during fish farming. Through the linkage design of the first and second opening / closing components, the rotating feed plate rotates, causing the first bevel gear to rotate as well. Power is transmitted via the first linkage rod to the second bevel gear, which in turn drives the rotating long plate to rotate. The rotation of the long plate, through a hinged rod, causes the opening / closing plate to slide symmetrically within the discharge pipe, achieving double-layer closure and opening of the discharge pipe. This effectively prevents moisture from contacting the fish food in the storage hopper, preventing the fish food from becoming damp and clumping, and avoiding the problem of moisture absorption inherent in traditional single-layer structures.

[0009] Meanwhile, the feed distribution component optimizes the feeding effect. Fish food falls into the water through the feed tray. When feeding stops, the rotation of the rotating plate drives the rotating ring to rotate through the second linkage rod, which in turn causes the feed tray to rotate, throwing off the fish food left on it, thus avoiding waste and pollution caused by fish food residue.

[0010] As a further improvement to this technical solution, a motor is installed on the outer wall of the discharge pipe, and the output shaft of the motor is coaxially connected to the rotation shaft of the material blocking disc.

[0011] This feature, which uses a motor to drive the rotating feed plate, provides a stable and controllable power source for the entire feeding device.

[0012] As a further improvement to this technical solution, a third bevel gear is welded and fixed at both the upper and lower ends of the first linkage rod. The upper third bevel gear meshes with the first bevel gear, and the lower third bevel gear meshes with the second bevel gear.

[0013] This setup ensures power transmission between the first and second bevel gears through the precise meshing of the third bevel gear, enabling the rotation of the material blocking disc to accurately drive the rotation of the rotating long plate, thereby achieving precise control over the opening and closing state of the discharge pipe.

[0014] As a further improvement to this technical solution, the upper and lower ends of the outer sidewall of the rotating long plate are welded and fixed with first hinge blocks, and the two opposite sidewalls of the opening and closing plate are welded and fixed with second hinge blocks. The two ends of the hinge rod are respectively hinged to the first hinge block and the second hinge block at the corresponding positions.

[0015] This design, through the arrangement of the first and second hinge blocks, provides a stable connection point for the hinge rod, ensuring that when the rotating plate rotates, the hinge rod can accurately drive the opening and closing plate to slide symmetrically.

[0016] As a further improvement to this technical solution, a slot is provided on the outer wall of the discharge pipe, and when the two opening and closing plates abut against each other, the discharge pipe is completely blocked.

[0017] This design, by creating a slot on the outer wall of the discharge pipe, provides precise guidance and limitation for the sliding of the opening and closing plates. This ensures that the two opening and closing plates can fit tightly together when they come into contact, completely blocking the discharge pipe and effectively preventing moisture from entering the storage tank, thus ensuring the dryness of the fish food.

[0018] As a further improvement to this technical solution, a fourth bevel gear and a first gear are welded and fixed at the upper and lower ends of the second linkage rod, respectively, and the fourth bevel gear meshes with the second bevel gear.

[0019] As a further improvement to this technical solution, tooth block assemblies are welded and fixed on opposite sides of the outer wall of the rotating ring, and the first gear meshes with the tooth block assemblies on the corresponding sides.

[0020] These two settings establish a power transmission path between the rotating plate and the rotating ring through the meshing of the fourth bevel gear and the second bevel gear, and the meshing of the first gear and the gear block assembly. When the rotating plate rotates, its power is transmitted sequentially through the second bevel gear, the fourth bevel gear, and the first gear to the gear block assembly, ultimately driving the rotating ring to rotate.

[0021] As a further improvement to this technical solution, several guide blades are regularly welded and fixed to the top of the material distribution plate, and the material distribution plate is located directly below the opening end of the discharge pipe.

[0022] This design involves regularly welding several guide blades to the top of the feed tray, allowing the fish food to be evenly dispersed along the guide blades as it falls. This effectively expands the distribution range of the fish food, prevents it from accumulating, and improves the uniformity and coverage of feeding.

[0023] As a further improvement to this technical solution, the outer diameter of the material blocking disc is equal to the inner diameter of the discharge pipe, and the material blocking disc is made of rigid plastic.

[0024] This design ensures that the outer diameter of the material blocking disc is equal to the inner diameter of the discharge pipe, thus preventing moisture from entering the storage tank.

[0025] As a further improvement to this technical solution, when the rotating long plate is in a vertical state, the two opening and closing plates abut against each other, completely blocking the discharge pipe; when the rotating long plate is in a horizontal state, the two opening and closing plates separate, completely exposing the inner opening of the discharge pipe.

[0026] This design allows for flexible control of the feeding pipe's opening and closing state by rotating the long plate in different positions. When feeding is needed, the motor drives the feed-blocking disc to rotate, which in turn causes the long plate to change from a vertical to a horizontal position. At this point, the two opening and closing plates separate, and the inner opening of the feeding pipe is fully exposed, allowing the fish food to fall smoothly. When feeding is finished, the motor reverses, the feed-blocking disc and the long plate return to their original positions, and the two opening and closing plates come together again, completely blocking the feeding pipe and effectively preventing moisture from entering, thus ensuring the fish food remains dry.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This fish farming feeding device, through the linkage design of the first and second opening and closing components, utilizes the rotation of the feed-blocking circular plate, which in turn rotates the first bevel gear. This rotation, via the first linkage rod, drives the rotating long plate to rotate. The rotation of the long plate, through the hinge rod, causes the opening and closing plate to slide symmetrically within the discharge pipe, achieving double-layer closure and opening of the discharge pipe. This effectively prevents moisture from contacting the fish food in the storage bin, preventing the fish food from becoming damp and clumping. Simultaneously, the design of the feed distribution component optimizes the feeding effect. The fish food falls through the feed distribution tray and disperses into the water, expanding the dispersion range and improving the uniformity and coverage of the feeding. When feeding stops, the feed distribution tray can also shake off any remaining fish food, avoiding waste and pollution caused by fish food residue.

[0028] 2. This fish farming feeding device disperses the falling fish food through the feed tray in the feed distribution component, so that the fish food can be more evenly distributed in the aquaculture water. When feeding stops, the rotating plate drives the rotating ring to rotate, and the feed tray rotates accordingly, throwing out the residual fish food, thus avoiding waste and pollution caused by fish food residue.

Furthermore, in the description of the invention, "a number" means two or more, unless otherwise explicitly specified.

[0033] Please see Figures 1-6 As shown, the present invention provides a fish farming feeding device, including a storage tank 100 and a mounting bracket 500 installed on the outer wall of the storage tank 100. The bottom end of the storage tank 100 is provided with a discharge pipe 110, and a first opening and closing component 200, a second opening and closing component 300 and a feed dispersing component 400 are installed in the discharge pipe 110 from top to bottom.

[0034] Considering that the fish food storage of the feeding device is located above the water body and is in close contact with water vapor, it is prone to moisture. Through the linkage mechanism of the first opening and closing component 200 and the second opening and closing component 300, the feed pipe 110 is double-closed, and at the same time, the feed dispersing component 400 disperses the fish food into the water.

[0035] For details, please refer to Figure 7 As shown, the first opening and closing assembly 200 includes a material-blocking circular plate 210 rotatably connected inside the discharge pipe 110 and two first bevel gears 220 respectively fixed on both sides of the rotation axis of the material-blocking circular plate 210. The outer diameter of the material-blocking circular plate 210 is equal to the inner diameter of the discharge pipe 110, and the material-blocking circular plate 210 is made of rigid plastic. A motor 230 is installed on the outer wall of the discharge pipe 110, and the output shaft of the motor 230 is coaxially connected to the rotation axis of the material-blocking circular plate 210.

[0036] When the motor 230 starts, its output shaft drives the rotating shaft of the material-blocking disc 210 to rotate, thereby causing the material-blocking disc 210 to rotate inside the discharge pipe 110. Since the outer diameter of the material-blocking disc 210 is equal to the inner diameter of the discharge pipe 110, and it is made of rigid plastic, the material-blocking disc 210 can tightly adhere to the inner wall of the discharge pipe 110 during rotation, effectively preventing moisture from entering the storage tank 100. Simultaneously, the two first bevel gears 220 rotate along with the rotation of the material-blocking disc 210.

[0037] In addition, please see Figure 8 and Figure 9 As shown, the second opening and closing assembly 300 includes a set of opening and closing plates 310 symmetrically slidably inserted into both sides of the discharge pipe 110, two rotating long plates 320 rotatably connected to both sides of the side wall of the discharge pipe 110, and two first linkage rods 350 rotatably connected to both sides of the side wall of the discharge pipe 110. A second bevel gear 330 is coaxially welded and fixed at the center of the inner side wall of the rotating long plate 320. The upper and lower ends of the outer side wall of the rotating long plate 320 are respectively hinged to the opening and closing plates 310 on both sides. The rotation of the first bevel gear 220 drives the rotating long plate 320 to rotate through the first linkage rods 350.

[0038] The rotation of the first linkage rod 350 drives the rotating plate 320 to rotate via the second bevel gear 330. The rotation of the rotating plate 320 drives the opening and closing plate 310 to slide symmetrically within the discharge pipe 110 via the hinge rod 340.

[0039] For further details, please refer to Figure 3 As shown, the first linkage rod 350 has a third bevel gear 351 welded and fixed at both the upper and lower ends. The upper third bevel gear 351 meshes with the first bevel gear 220, and the lower third bevel gear 351 meshes with the second bevel gear 330.

[0040] When the motor 230 starts and drives the material-blocking disc 210 to rotate, the first bevel gear 220 rotates accordingly. Through meshing with the upper third bevel gear 351, it causes the first linkage rod 350 to rotate. The lower third bevel gear 351 at the lower end of the first linkage rod 350 meshes with the second bevel gear 330, transmitting power to the rotating long plate 320 and driving it to rotate around the central axis.

[0041] For details, please refer to Figure 9As shown, the upper and lower ends of the outer sidewall of the rotating long plate 320 are welded and fixed with first hinge blocks 321, and the two opposite sidewalls of the opening and closing plate 310 are welded and fixed with second hinge blocks 311. The two ends of the hinge rod 340 are respectively hinged to the first hinge block 321 and the second hinge block 311 at the corresponding positions. The setting of the first hinge block 321 and the second hinge block 311 provides a stable connection point for the hinge rod 340, ensuring that the rotating long plate 320 can drive the opening and closing plate 310 to slide precisely and symmetrically in the discharge pipe 110 through the hinge rod 340 during the rotation process.

[0042] It is worth noting that, please refer to Figure 6 As shown, a slot 111 is provided on the outer wall of the discharge pipe 110. When the two opening and closing plates 310 abut against each other, the discharge pipe 110 is completely blocked. The slot 111 provides precise guidance and limiting for the sliding of the opening and closing plates 310, ensuring that the two opening and closing plates 310 can fit tightly when they abut against each other, completely blocking the discharge pipe 110, effectively preventing moisture from entering the storage tank 100, and ensuring the dryness of the fish food.

[0043] For further details, please refer to Figure 10 As shown, the bulk material assembly 400 includes a rotating ring 410 rotatably connected to the inner wall of the discharge pipe 110, a connecting frame 420 welded and fixed to the bottom end of the rotating ring 410, a bulk material tray 430 welded and fixed to the bottom end of the connecting frame 420, and two second linkage rods 440 rotatably connected to the inner sides of the side wall of the discharge pipe 110; the rotating plate 320 rotates and drives the rotating ring 410 to rotate through the second linkage rods 440.

[0044] The falling fish food is evenly distributed into the aquaculture area via the feed tray 430. When feeding stops, the second linkage 440 rotates, causing the rotating ring 410 to rotate. The rotating ring 410 drives the feed tray 430 to rotate, throwing out any remaining fish food and further avoiding waste and pollution.

[0045] For details, please refer to Figure 4 and Figure 5 As shown, the second linkage rod 440 has a fourth bevel gear 441 and a first gear 442 welded and fixed at its upper and lower ends, respectively. The fourth bevel gear 441 meshes with the second bevel gear 330. The outer side of the rotating ring 410 has a tooth block assembly 411 welded and fixed on opposite sides. The first gear 442 meshes with the tooth block assembly 411 on the corresponding side.

[0046] The rotation of the material-blocking circular plate 210 drives the first bevel gear 220 to rotate. The first bevel gear 220 drives the second bevel gear 330 to rotate via the first linkage rod 350. The second bevel gear 330 meshes with the fourth bevel gear 441, thereby driving the second linkage rod 440 to rotate. The first gear 442 at the lower end of the second linkage rod 440 meshes with the tooth block assembly 411 on the outer wall of the rotating ring 410. When the second linkage rod 440 rotates, the meshing transmission between the first gear 442 and the tooth block assembly 411 drives the rotating ring 410 to rotate around the inner wall of the discharge pipe 110.

[0047] Specifically, several guide blades 431 are regularly welded and fixed to the top of the feed tray 430, which is located directly below the opening of the discharge pipe 110. When fish food falls from the discharge pipe 110, it first comes into contact with the guide blades 431 at the top of the feed tray 430. These guide blades 431 are regularly arranged and can evenly disperse the falling fish food, causing it to fall in different directions, thereby expanding the dispersion range of the fish food in the aquaculture water.

[0048] Furthermore, when the rotating long plate 320 is in a vertical state, the two opening and closing plates 310 abut against each other, completely blocking the discharge pipe 110. When the rotating long plate 320 is in a horizontal state, the two opening and closing plates 310 separate, completely exposing the inner opening of the discharge pipe 110. During feeding, when fish food needs to be added, the long plate 320 is rotated from a vertical position to a horizontal position, fully exposing the inner opening of the feed pipe 110, allowing the fish food to fall smoothly. When feeding is finished, the long plate 320 is rotated back to a vertical position, and the two opening and closing plates 310 abut against each other again, completely blocking the feed pipe 110, effectively preventing moisture from entering and ensuring the dryness of the fish food.

[0049] When the fish farming feeding device of the present invention is in operation, firstly, the entire feeding device is securely installed in a suitable position above the water body by the mounting bracket 500 to ensure that the storage tank 100 is in a relatively stable state.

[0050] When feeding, start the motor 230. The output shaft of the motor 230 drives the rotating shaft of the feed blocking plate 210 to rotate. The feed blocking plate 210 rotates inside the discharge pipe 110, causing the fish food to fall.

[0051] Simultaneously, the two first bevel gears 220 rotate synchronously with the material-blocking circular plate 210. The first bevel gears 220, through meshing with the upper third bevel gear 351, cause the first linkage rod 350 to rotate. The lower third bevel gear 351 at the lower end of the first linkage rod 350 meshes with the second bevel gear 330, transmitting power to the rotating long plate 320, driving it to rotate around the central axis. The rotation of the rotating long plate 320, through the hinge rod 340, causes the opening and closing plate 310 to slide symmetrically within the discharge pipe 110. The two opening and closing plates 310, which were originally in a contacting state, gradually separate. When the rotating long plate 320 is in a horizontal state, the two opening and closing plates 310 are completely separated, and the inner opening of the discharge pipe 110 is fully exposed, allowing the fish food to fall smoothly from the storage tank 100 through the discharge pipe 110.

[0052] During the falling process, the fish food first comes into contact with the guide blades 431 at the top of the feed tray 430, which evenly disperses the falling fish food, causing it to fall in different directions.

[0053] When feeding stops, motor 230 reverses, the feed-blocking disc 210 rotates in the opposite direction, and the first bevel gear 220 also rotates in the opposite direction. Through a series of gear transmissions, the rotating plate 320 is driven to gradually rotate from a horizontal state back to a vertical state. During the rotation of the rotating plate 320, the second bevel gear 330 meshes with the fourth bevel gear 441, driving the second linkage rod 440 to rotate. The first gear 442 at the lower end of the second linkage rod 440 meshes with the tooth block assembly 411 on the outer wall of the rotating ring 410, driving the rotating ring 410 to rotate around the inner wall of the discharge pipe 110. The rotating ring 410 drives the feed tray 430 to rotate, throwing off the fish food left on the feed tray 430, avoiding waste and pollution caused by fish food residue.

[0054] At the same time, as the rotating long plate 320 returns to its vertical position, the two opening and closing plates 310 abut against each other again, completely blocking the discharge pipe 110. Together with the material blocking round plate 210, a double-layer closure is formed, which effectively prevents water vapor from entering and ensures the dryness of the fish food.

[0055] It should be noted that the above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
