Description

Technical Field

[0001] This invention relates to aquaculture technology, specifically to a pellet feed feeding device and method for aquaculture. Background Technology

[0002] Aquaculture is an important part of my country's agricultural economy. With the continuous expansion of aquaculture scale and the improvement of intensification, pelleted feed has gradually replaced traditional feeds such as fresh fish due to its advantages such as balanced nutrition, convenient feeding and less waste, and has become the most important feeding form in aquaculture.

[0003] Traditional feeding devices mostly use gravity-based continuous feeding, which makes it difficult to control the amount of feed and cannot achieve intermittent or pulsed feeding. This is not conducive to fish developing a good feeding rhythm, nor is it conducive to the effective diffusion of feed in the water. Therefore, a pellet feed feeding device and method for aquaculture is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a pellet feed feeding device and method for aquaculture, in order to solve the problem that existing feeding devices mostly adopt gravity-based continuous feeding methods, which are not conducive to fish forming a good feeding rhythm and effective feed diffusion in water.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pellet feed feeding device for aquaculture, comprising a U-shaped support, and further comprising:

[0006] Feeding boxes are used to store pelleted feed for aquaculture.

[0007] A reciprocating moving mechanism is used to move and adjust the position of the feeding box, and the reciprocating moving mechanism is mounted on the U-shaped bracket;

[0008] A stirring and feeding mechanism is used to stir the pelleted feed inside the feeding box and to reciprocate the feeding of the pelleted feed. The stirring and feeding mechanism is installed on the reciprocating moving mechanism. The stirring and feeding mechanism includes a second rotary drive component installed on the top of the inner wall of the feeding box. The output end of the second rotary drive component is fixedly connected to a rotating shaft. Multiple first stirring plates and a second stirring plate are fixedly connected to the outer wall of the rotating shaft. A limiting vertical groove is opened on one side of the inner wall of the feeding box. A telescopic element is fixedly connected to the bottom of the inner wall of the limiting vertical groove. A sliding plate is fixedly connected to the top of the telescopic element. A fixed magnetic plate and an mounting magnetic plate are fixedly connected to the top of the sliding plate and the bottom of the second stirring plate, respectively. A connecting rod is fixedly connected to the bottom of the sliding plate. A closing plate is fixedly connected to the bottom of the connecting rod.

[0009] The dispensing mechanism is used to repeatedly add additives to the pelleted feed during feeding, and the dispensing mechanism is installed on the feeding box.

[0010] Furthermore, the reciprocating moving mechanism includes a limiting slide groove formed on the top of the inner wall of the U-shaped bracket. A first rotary drive member is fixedly connected to the outer wall of the U-shaped bracket. A reciprocating screw is fixedly connected to the output end of the first rotary drive member. The end of the reciprocating screw away from the first rotary drive member extends rotatably into the interior of the limiting slide groove. A moving plate is threadedly connected to the outer wall of the reciprocating screw inside the limiting slide groove. The bottom end of the moving plate extends to the outside of the limiting slide groove.

[0011] Furthermore, the outer wall of the movable plate and the inner wall of the limiting groove are slidably fitted together, and the feeding box is fixedly installed at the bottom end of the movable plate.

[0012] Furthermore, the dispensing mechanism includes a storage box fixedly installed on the outer wall of the feeding box. A connecting slide plate is slidably connected inside the storage box, and the top of the connecting slide plate extends slidably to the outside of the storage box. A shielding magnetic plate is fixedly connected to the bottom of the connecting slide plate inside the storage box. A fixing magnetic block is fixedly connected to one side of the inner wall of the storage box. A connecting baffle is fixedly connected to the top of the sliding plate inside the limiting vertical groove.

[0013] Furthermore, a dispensing port is provided on one side of the bottom of the storage tank, and the dispensing port extends into the interior of the limiting vertical groove. The connecting baffle and the shielding magnetic plate are respectively attached to both sides of the dispensing port.

[0014] Furthermore, the bottom of the feeding box is provided with a discharge port, the sealing plate is located inside the discharge port, and the outer side wall of the sealing plate is slidably fitted with the inner side wall of the discharge port, and the top of the sealing plate is arc-shaped.

[0015] Furthermore, the outer wall of the sliding plate and the inner wall of the limiting vertical groove are slidably fitted together, the fixed magnetic plate and the mounting magnetic plate are correspondingly opposite poles, and the top of the feeding box is provided with a feeding port.

[0016] A method for feeding pelleted feed for aquaculture includes the following steps:

[0017] Step 1: When in use, the U-shaped bracket is installed inside the aquaculture pond so that the feeding box is above the water surface; start the first rotary drive component to drive the reciprocating screw to rotate. When the reciprocating screw rotates, the moving plate is correspondingly subjected to the thread transmission to make reciprocating linear motion in the limit slide groove, thereby driving the feeding box fixedly installed at the bottom of the moving plate to move back and forth on the U-shaped bracket.

[0018] Step 2: Activate the second rotary drive unit. The second rotary drive unit drives the rotating shaft to rotate. When the rotating shaft rotates, it drives multiple first stirring plates and one second stirring plate fixedly connected to its outer wall to rotate synchronously. The multiple first stirring plates continuously stir the pellet feed inside the feeding box.

[0019] Step 3: The mounting magnetic plate fixedly connected to the bottom of the second mixing plate rotates together with the second mixing plate; when the mounting magnetic plate rotates to the position corresponding to the fixed magnetic plate fixed on the top of the sliding plate, since the fixed magnetic plate and the mounting magnetic plate are set with the same poles repelling each other, a repulsive force is generated between them, pushing the sliding plate to slide down along the limiting vertical groove; driving the connecting rod and the sealing plate fixedly connected to its bottom to move down synchronously, so that the sealing plate disengages from the discharge port at the bottom of the feeding box, and the pellet feed inside the feeding box can flow out through the discharge port and fall into the pond;

[0020] Step 4: The staff pulls the connecting slide upwards, which causes the shielding magnetic plate fixed at its bottom to slide upwards, so that the shielding magnetic plate is separated from the outlet at the bottom of the storage tank. At the same time, the shielding magnetic plate and the fixed magnetic block fixed on one side of the inner wall of the storage tank attract each other, limiting and fixing the shielding magnetic plate above the outlet.

[0021] Step 5: During the feeding process, the sliding plate moves up and down reciprocally with the rotation of the second stirring plate, which causes the connecting baffle to move up and down with the sliding plate and reciprocate synchronously; accordingly, the connecting baffle repeatedly blocks and separates from the outlet, allowing the additive to flow out repeatedly.

[0022] Compared with the prior art, the present invention provides a pellet feed feeding device and method for aquaculture. By setting up a stirring feeding mechanism, multiple first stirring plates and second stirring plates can continuously stir the pellet feed inside the feeding box, effectively preventing the feed from absorbing moisture, clumping, and deteriorating in high temperature and humidity environments, and ensuring the palatability and nutritional consistency of the feed. When the second stirring plate drives the magnetic plate installed at its bottom to rotate, the pellet feed can flow back and forth through the discharge port, which is conducive to the smooth flow of feed and reduces residue. This structure realizes the synchronization of stirring and pulsed intermittent feeding, and the feeding rhythm can be controlled, which is conducive to fish forming a good feeding rhythm and improving feed utilization.

[0023] By setting up a dispensing mechanism, during the feeding process, the sliding plate moves up and down reciprocally with the rotation of the second stirring plate, which allows the connecting baffle to move up and down with the sliding plate and reciprocate synchronously. Correspondingly, the connecting baffle reciprocates to block and disengage from the dispensing port, allowing the additive to flow out reciprocally. This structure cleverly utilizes the reciprocating motion of the sliding plate in the stirring and feeding mechanism to achieve automatic reciprocating quantitative addition of the additive without an additional drive source. After the additive is fully mixed with the pelleted feed stirred by the first and second stirring plates inside the feeding box, it is fed into the pond through the discharge port.

[0034] As attached Figure 1 To be continued Figure 6 As shown:

[0035] Example 1:

[0036] This invention provides a pellet feed feeding device for aquaculture, including a U-shaped support 1, and further comprising:

[0037] Feeding box 3 is used to store pelleted feed for aquaculture;

[0038] A reciprocating moving mechanism is used to move and adjust the position of the feeding box 3. The reciprocating moving mechanism is installed on the U-shaped bracket 1. The reciprocating moving mechanism includes a limiting slide groove 2 opened on the top of the inner wall of the U-shaped bracket 1. A first rotary drive member 201 is fixedly connected to the outer wall of the U-shaped bracket 1. A reciprocating screw 202 is fixedly connected to the output end of the first rotary drive member 201. The end of the reciprocating screw 202 away from the first rotary drive member 201 extends rotatably into the interior of the limiting slide groove 2. A moving plate 203 is threadedly connected to the outer wall of the reciprocating screw 202 inside the limiting slide groove 2. The bottom end of the moving plate 203 extends to the outside of the limiting slide groove 2.

[0039] A stirring and feeding mechanism is used to stir the pellet feed inside the feeding box 3 and to reciprocate feeding the pellet feed. The stirring and feeding mechanism is installed on the reciprocating moving mechanism. The stirring and feeding mechanism includes a second rotary drive 301 installed on the top of the inner wall of the feeding box 3. The output end of the second rotary drive 301 is fixedly connected to a rotating shaft 302. Multiple first stirring plates 303 and a second stirring plate 304 are fixedly connected to the outer wall of the rotating shaft 302. A limiting vertical groove 305 is opened on one side of the inner wall of the feeding box 3. A telescopic element 306 is fixedly connected to the bottom of the inner wall of the limiting vertical groove 305. A sliding plate 307 is fixedly connected to the top of the telescopic element 306. A fixed magnetic plate 308 and an mounting magnetic plate 309 are fixedly connected to the top of the sliding plate 307 and the bottom of the second stirring plate 304, respectively. A connecting rod 3010 is fixedly connected to the bottom of the sliding plate 307. A closing plate 3011 is fixedly connected to the bottom of the connecting rod 3010.

[0040] The present invention is further described in detail as follows: the outer wall of the movable plate 203 and the inner wall of the limiting groove 2 are slidably fitted together; the feeding box 3 is fixedly installed at the bottom of the movable plate 203; the bottom of the feeding box 3 is provided with a discharge port; the sealing plate 3011 is located inside the discharge port; the outer wall of the sealing plate 3011 and the inner wall of the discharge port are slidably fitted together; the top of the sealing plate 3011 is arc-shaped; the outer wall of the sliding plate 307 and the inner wall of the limiting vertical groove 305 are slidably fitted together; the fixed magnetic plate 308 and the mounting magnetic plate 309 are correspondingly like poles and repulsive; the top of the feeding box 3 is provided with a feeding port.

[0041] Working principle: In use, the U-shaped bracket 1 is installed inside the aquaculture pond, so that the feeding box 3 is located above the water surface; the first rotary drive 201 is started, which drives the reciprocating screw 202 to rotate. When the reciprocating screw 202 rotates, since the moving plate 203 is threadedly connected to the reciprocating screw 202, and the outer wall of the moving plate 203 is slidably fitted with the inner wall of the limiting slide groove 2, the moving plate 203 makes reciprocating linear motion in the limiting slide groove 2 under the action of the threaded transmission, thereby driving the feeding box 3, which is fixedly installed at the bottom of the moving plate 203, to move back and forth on the U-shaped bracket 1, so as to realize the lateral adjustment of the feeding position and expand the feeding coverage area.

[0042] The second rotary drive 301 is activated, which drives the rotating shaft 302 to rotate. When the rotating shaft 302 rotates, it drives multiple first stirring plates 303 and a second stirring plate 304 fixedly connected to its outer wall to rotate synchronously. The multiple first stirring plates 303 continuously stir the pellet feed inside the feeding box 3 to prevent the feed from clumping, absorbing moisture and deteriorating, and to improve the palatability and feeding quality of the feed.

[0043] Meanwhile, the mounting magnetic plate 309, fixedly connected to the bottom of the second stirring plate 304, rotates together with the second stirring plate 304. When the mounting magnetic plate 309 rotates to the position corresponding to the fixed magnetic plate 308 fixed to the top of the sliding plate 307, since the fixed magnetic plate 308 and the mounting magnetic plate 309 are set with the same poles repelling each other, a repulsive force is generated between them. This repulsive force overcomes the elastic force of the telescopic element 306 and pushes the sliding plate 307 to slide downward along the limiting vertical groove 305. When the sliding plate 307 slides downward, it drives the connecting rod 3010 fixedly connected to its bottom and... The closing plate 3011 moves downward synchronously, causing it to detach from the discharge port at the bottom of the feeding box 3. The pelleted feed inside the feeding box 3 can then flow out through the discharge port and fall into the pond. When the mounting magnetic plate 309 rotates away from the position of the fixed magnetic plate 308, the repulsive force disappears, and the elastic force of the telescopic element 306 pushes the sliding plate 307 to reset. The closing plate 3011 then re-closes the discharge port, stopping the feeding. The top of the closing plate 3011 is arc-shaped, which facilitates the smooth flow of feed and reduces residue. This cycle repeats, achieving pulsed intermittent feeding of pelleted feed.

[0044] With the above technical solution, by setting a reciprocating moving mechanism, the first rotary drive component 201 drives the reciprocating screw 202 to rotate. The moving plate 203, which is threadedly connected to the reciprocating screw 202 and the limiting slide groove 2, makes reciprocating linear motion under the limiting and guiding action of the limiting slide groove 2. The moving plate 203 drives the feeding box 3, which is fixedly installed at its bottom end, to move laterally reciprocally on the U-shaped bracket 1. This structure makes the feeding position of the feeding box 3 no longer fixed at a single point, but periodically reciprocates along the surface of the pond, effectively expanding the feeding coverage of pellet feed, avoiding the problem of feed accumulation in local water areas and insufficient feeding of fish in distant areas, improving the uniformity of fish feeding in the aquaculture area, and reducing feed waste and water pollution.

[0045] By setting up a stirring and feeding mechanism, the second rotary drive 301 drives the rotating shaft 302 to rotate. Multiple first stirring plates 303 fixedly connected to the outer wall of the rotating shaft 302 continuously stir the pelleted feed inside the feeding box 3, effectively preventing the feed from absorbing moisture, clumping, and deteriorating under high temperature and humidity conditions, thus ensuring the palatability and nutritional consistency of the feed. Simultaneously, the rotating shaft 302 drives the second stirring plate 304 to rotate, and the mounting magnetic plate 309 at the bottom of the second stirring plate 304 rotates synchronously with it. When the mounting magnetic plate 309 rotates to the position corresponding to the fixed magnetic plate 308 fixed to the top of the sliding plate 307, since the fixed magnetic plate 308 and the mounting magnetic plate 309 are set with the same poles repelling each other, a repulsive force is generated between them. This repulsive force overcomes… The elastic force of the telescopic element 306 pushes the sliding plate 307 to slide downward along the limiting vertical groove 305. The sliding plate 307 drives the connecting rod 3010 and the closing plate 3011 to move downward synchronously, so that the closing plate 3011 disengages from the discharge port at the bottom of the feeding box 3, and the pellet feed can flow out through the discharge port. When the installed magnetic plate 309 rotates away from the fixed magnetic plate 308, the repulsive force disappears, and the elastic force of the telescopic element 306 pushes the sliding plate 307 to reset, and the closing plate 3011 re-closes the discharge port. The top of the closing plate 3011 is arc-shaped, which is conducive to the smooth flow of feed and reduces residue. This structure realizes the synchronous operation of stirring and pulse intermittent feeding, the feeding rhythm is controllable, which is conducive to fish forming a good feeding rhythm and improving feed utilization.

[0046] Example 2:

[0047] This embodiment is basically the same as the previous embodiment, except that the dispensing mechanism is used to repeatedly add additives to the inside of the pelleted feed when feeding it. The dispensing mechanism is installed on the feeding box 3. The dispensing mechanism includes a storage box 4 fixedly installed on the outer wall of the feeding box 3. A connecting slide plate 401 is slidably connected inside the storage box 4, and the top of the connecting slide plate 401 slides to the outside of the storage box 4. A shielding magnetic plate 402 is fixedly connected to the bottom of the connecting slide plate 401 inside the storage box 4. A fixing magnetic block 403 is fixedly connected to one side of the inner wall of the storage box 4. A connecting baffle 404 is fixedly connected to the top of the sliding plate 307 inside the limiting vertical groove 305.

[0048] The present invention is further described in detail. A dispensing port is provided on one side of the bottom of the storage tank 4, and the dispensing port extends into the interior of the limiting vertical groove 305. The connecting baffle 404 and the shielding magnetic plate 402 are respectively attached to both sides of the dispensing port.

[0049] Working principle: Functional additives need to be added simultaneously when feeding fish under the following conditions: high temperature season, after transportation, after transfer to another pond, water quality is too fertile during high temperature period, fish have intestinal problems, long-term feeding of frozen fish or high-fat feed, deterioration of the bottom of high-density farming, high pH of alkaline water, and feeding feed with a high proportion of plant protein.

[0050] Before use, the staff pulls the connecting slide plate 401 upwards. The connecting slide plate 401 causes the blocking magnetic plate 402 fixedly connected at its bottom to slide upwards, so that the blocking magnetic plate 402 is separated from the dispensing port at the bottom of the storage tank 4. At the same time, the blocking magnetic plate 402 and the fixed magnetic block 403 fixed on one side of the inner wall of the storage tank 4 attract each other with opposite poles, limiting and fixing the blocking magnetic plate 402 above the dispensing port. The additives (such as vitamin C / immunopolysaccharides, probiotics, allicin / liver and gallbladder protectants, EM bacteria / bottom-modifying complexes, organic acids, enzyme preparations, etc.) inside the storage tank 4 are in a state of waiting to be released.

[0051] During the feeding process, the sliding plate 307 moves up and down reciprocally with the rotation of the second stirring plate 304. When the sliding plate 307 moves downward, the connecting baffle 404 fixed at the top of the sliding plate 307 moves downward synchronously with the sliding plate 307, causing the connecting baffle 404 to detach from the outlet. At this time, the additive inside the storage tank 4 flows into the limiting vertical groove 305 through the outlet under the action of gravity and enters the feeding box 3, where it mixes with the pellet feed inside the feeding box 3. When the sliding plate 307 returns to its original position, the connecting baffle 404 re-attaches to the outlet, while the blocking magnetic plate 402 is still attracted and limited by the fixed magnetic block 403, preventing the additive from continuously flowing out. In this way, the connecting baffle 404, with the reciprocating motion of the sliding plate 307, realizes the periodic opening and closing of the outlet, allowing the additive to flow back and forth and quantitatively into the feeding box 3. After being fully mixed with the pellet feed, it is fed into the pond through the outlet, thereby enhancing the fish's immunity and growth efficiency.

[0052] In summary, this invention achieves lateral adjustment of the feeding position through a reciprocating moving mechanism, continuous stirring and pulsed intermittent feeding of feed through a stirring feeding mechanism, and automatic reciprocating addition of additives through a dispensing mechanism utilizing the motion power of the stirring feeding mechanism. The three mechanisms work together to significantly improve the accuracy, uniformity, and functionality of pelleted feed for aquaculture.

[0053] With the above technical solution, by setting up the dispensing mechanism, the storage tank 4 is fixedly installed on the outer wall of the feeding box 3. After the connecting slide plate 401 inside the storage tank 4 is pulled upward, it causes the shielding magnetic plate 402 to disengage from the dispensing port and be attracted and fixed by the opposite poles of the fixed magnetic block 403, and the storage tank 4 is in a ready-to-release state. During the feeding process, the sliding plate 307 moves back and forth up and down with the rotation of the second stirring plate 304, and the connecting baffle 404 fixed on the top of the sliding plate 307 moves back and forth synchronously with the sliding plate 307. When the connecting baffle 404 moves downward and disengages from the dispensing port... At that time, the additive inside the storage tank 4 flows into the limiting vertical groove 305 through the outlet under the action of gravity and enters the feeding box 3; when the connecting baffle 404 is reset upward and attached to the outlet, the outlet is re-closed and the additive stops flowing out; this structure cleverly utilizes the reciprocating motion power of the sliding plate 307 in the stirring and feeding mechanism, and can realize the automatic reciprocating quantitative addition of additives without the need for an additional drive source. After the additives are fully mixed with the pellet feed stirred by the first stirring plate 303 and the second stirring plate 304 inside the feeding box 3, they are fed into the pond together through the discharge port.

[0054] The dispensing mechanism of this device can simultaneously add functional additives such as Vitamin C / immunopolysaccharides, probiotics (lactic acid bacteria, etc.), allicin / hepatobiliary protectants, EM bacteria / bottom conditioners, organic acids (citric acid, etc.), and enzyme preparations (protease, amylase) under various special conditions, including high-temperature seasons, after transportation, after pond transfer, high-temperature water quality with eutrophication, fish intestinal problems, long-term feeding of frozen fish or high-fat feed, bottom deterioration in high-density farming, high pH in alkaline water, and feed with a high proportion of plant protein. These additives can specifically enhance fish immunity, improve intestinal health, regulate water quality, and promote digestion and absorption, significantly improving fish growth efficiency and farming benefits.

[0055] Example 3:

[0056] A method for feeding pelleted feed for aquaculture includes the following steps:

[0057] Step 1: When in use, the U-shaped bracket 1 is installed inside the aquaculture pond, so that the feeding box 3 is located above the water surface; start the first rotary drive component 201, which drives the reciprocating screw 202 to rotate. When the reciprocating screw 202 rotates, the moving plate 203 is correspondingly subjected to the thread transmission and makes reciprocating linear motion in the limiting slide groove 2, thereby driving the feeding box 3, which is fixedly installed at the bottom of the moving plate 203, to reciprocate on the U-shaped bracket 1.

[0058] Step 2: Start the second rotary drive 301. The second rotary drive 301 drives the rotating shaft 302 to rotate. When the rotating shaft 302 rotates, it drives multiple first stirring plates 303 and a second stirring plate 304 fixedly connected to its outer wall to rotate synchronously. The multiple first stirring plates 303 continuously stir the pellet feed inside the feeding box 3.

[0059] Step 3: The mounting magnetic plate 309, which is fixedly connected to the bottom of the second stirring plate 304, rotates together with the second stirring plate 304. When the mounting magnetic plate 309 rotates to the position corresponding to the fixed magnetic plate 308 fixed on the top of the sliding plate 307, since the fixed magnetic plate 308 and the mounting magnetic plate 309 are set with the same poles repelling each other, a repulsive force is generated between them, pushing the sliding plate 307 to slide downward along the limiting vertical groove 305. This causes the connecting rod 3010 and the closing plate 3011, which are fixedly connected to its bottom, to move downward synchronously, so that the closing plate 3011 is separated from the discharge port at the bottom of the feeding box 3, and the pellet feed inside the feeding box 3 can flow out through the discharge port and fall into the pond.

[0060] Step 4: The staff pulls the connecting slide plate 401 upwards, which causes the shielding magnetic plate 402 fixedly connected to its bottom end to slide upwards, so that the shielding magnetic plate 402 is disengaged from the outlet at the bottom of the storage tank 4. At the same time, the shielding magnetic plate 402 and the fixed magnetic block 403 fixed on one side of the inner wall of the storage tank 4 attract each other with opposite poles, thus limiting and fixing the shielding magnetic plate 402 above the outlet.

[0061] Step 5: During the feeding process, the sliding plate 307 moves up and down reciprocally with the rotation of the second stirring plate 304, which causes the connecting baffle 404 to move up and down with the sliding plate 307 and reciprocate synchronously; accordingly, the connecting baffle 404 reciprocates to block and detach from the outlet, allowing the additive to flow out reciprocally.

[0062] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

7. The pellet feed feeding device for aquaculture according to claim 4, characterized in that, The outer wall of the sliding plate (307) and the inner wall of the limiting vertical groove (305) are slidably fitted together. The fixed magnetic plate (308) and the mounting magnetic plate (309) are arranged with corresponding like poles and repulsion. The top of the feeding box (3) is provided with a feeding port.

8. A method for feeding pelleted feed for aquaculture based on the apparatus according to any one of claims 1-7, characterized in that, Includes the following steps: Step 1: When in use, the U-shaped bracket (1) is installed inside the aquaculture pond so that the feeding box (3) is above the water surface; start the first rotary drive (201) to drive the reciprocating screw (202) to rotate. When the reciprocating screw (202) rotates, the moving plate (203) is driven by the screw to make reciprocating linear motion in the limiting slide groove (2), thereby driving the feeding box (3) fixedly installed at the bottom of the moving plate (203) to move back and forth on the U-shaped bracket (1); Step 2: Start the second rotary drive (301). The second rotary drive (301) drives the rotating shaft (302) to rotate. When the rotating shaft (302) rotates, it drives multiple first stirring plates (303) and a second stirring plate (304) fixedly connected to its outer wall to rotate synchronously. The multiple first stirring plates (303) continuously stir the pellet feed inside the feeding box (3). Step 3: The mounting magnetic plate (309) fixedly connected to the bottom of the second stirring plate (304) rotates together with the second stirring plate (304); when the mounting magnetic plate (309) rotates to the position corresponding to the fixed magnetic plate (308) fixed on the top of the sliding plate (307), since the fixed magnetic plate (308) and the mounting magnetic plate (309) are set with the same poles repelling each other, a repulsive force is generated between them, pushing the sliding plate (307) to slide down along the limiting vertical groove (305); driving the connecting rod (3010) and the closing plate (3011) fixedly connected to its bottom to move down synchronously, so that the closing plate (3011) is separated from the discharge port at the bottom of the feeding box (3), and the pellet feed inside the feeding box (3) can flow out through the discharge port and fall into the pond; Step 4: The staff pulls the connecting slide plate (401) upwards. The connecting slide plate (401) drives the shielding magnetic plate (402) fixedly connected at its bottom to slide upwards, so that the shielding magnetic plate (402) is separated from the outlet at the bottom of the storage tank (4). At the same time, the shielding magnetic plate (402) and the fixed magnetic block (403) fixed on one side of the inner wall of the storage tank (4) attract each other with opposite poles, limiting and fixing the shielding magnetic plate (402) above the outlet. Step 5: During the feeding process, the sliding plate (307) moves up and down back and forth with the rotation of the second stirring plate (304), which allows the connecting baffle (404) to move up and down with the sliding plate (307) and move back and forth synchronously; accordingly, the connecting baffle (404) is repeatedly blocked and separated from the outlet, allowing the additive to flow out repeatedly.
