Description

Technical Field

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

[0002] Aquaculture is an important part of the global food supply chain, providing humans with high-quality animal protein. Feed costs typically account for 60% to 70% of total aquaculture costs. Therefore, feeding management is a core element determining the success or failure and profitability of aquaculture.

[0003] When feeding aquaculture ponds, a rotating feeder is typically placed on the water surface to distribute the mixed feed. The feeder relies on the centrifugal force generated by its rotation to scatter the feed. Because the rotating feeder scatters the feed further away, the feed tends to land further away from the feeder, resulting in less feed near the feeder. This can lead to uneven distribution of feed on the water surface, affecting feeding efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a feeding device for aquaculture to solve the problems mentioned in the background art.

[0025] Furthermore, a number of arc-shaped plates are slidably connected to the outer surface of the sliding ring, and a rotating ring is rotatably connected to the end of the arc-shaped plates away from the sliding ring;

[0028] Furthermore, the connecting ear is rotatably connected to the side wall of the fixing ring, and the side wall of the fixing ring is fixedly connected to the inclined plate.

[0029] The rotating assembly includes a fixed ring 2 fixedly connected to the side wall of the connecting ear, and a number of triangular plates rotatably connected to the outer surface of the fixed ring 2. An inclined plate 2 is fixedly connected to the side wall of the triangular plates.

[0030] A spring plate is provided on the side of the triangular plate near the first fixed ring, and several spring plates are fixedly connected to the side wall of the second fixed ring.

[0031] The elastic end of the spring plate is fixedly connected to the side wall of the triangular plate.

[0032] Furthermore, a fixing plate is fixedly connected to the side wall of the second fixing ring, and an auxiliary spring is fixedly connected to the side wall of the fixing plate. The end of the auxiliary spring away from the second fixing ring is fixedly connected to the side wall of the first fixing ring.

[0035] The present invention has the following beneficial effects:

[0036] 1. In this invention, when the fixed ring two is impacted by the material, it stretches the auxiliary spring and swings back and forth under the elasticity of the auxiliary spring. The swinging of the fixed ring two will periodically block the spilled material and reduce the spilling speed of this part of the material, making it difficult for this part of the material to obtain sufficient centrifugal force and thus scatter towards the vicinity of the feeding pipe. In this way, the uniformity and coverage of the bait can be improved during the feeding process, reducing the occurrence of blank feeding circles around the feeding pipe during the feeding process, and improving the feeding efficiency.

[0037] 2. In this invention, when the second fixed ring rotates outward and then resets under the tension of the auxiliary spring, the second fixed ring pushes the tripod through the fixed plate. At this time, the tripod, after being pushed, will push the sliding ring to reset. Thus, when the material continues to be conveyed, the arc plate can rotate back and forth inside the material and generate a stirring force on the material. By stirring the material, the accumulation and blockage of some material in the feeding pipe due to the reduced speed of spillage at the outlet end of the feeding pipe and the material's own wet and sticky properties can be reduced. This improves the continuity of material feeding and also improves the stability of the feeding process.

[0038] 3. In this invention, when the spiral shaft is sliding, the spiral shaft can drive the material pushed by the arc plate to flow when the arc plate rotates and expands outward. At this time, the material can be driven by the spiral shaft to reduce the excessive pushing by the arc plate, thereby reducing the excessive breakage of the material when multiple arc plates expand and rotate outward, thus improving the integrity of the material particles during feeding, and further improving the uniformity and feeding efficiency.

[0039] 4. This invention can reduce the amount of material residue adhering to the inner wall of the feeding pipe after feeding by cleaning the inner wall of the feeding pipe. It can also reduce the hardening of material due to long-term residue in the feeding pipe, which would affect the flow area of ​​the feeding pipe channel and ensure the stability of the flow area of ​​subsequent materials through the feeding pipe. At the same time, it can also ensure the cleanliness of the feeding pipe after feeding, and further improve the feeding efficiency of subsequent feeding.

[0056] The active mechanism 2 is installed on the top of the main body 1 to improve the uniformity of material feeding during feeding.

[0057] Auxiliary mechanism 3 is installed on the side wall of the movable mechanism 2 to prevent the bait from getting clogged during the feeding process.

[0058] Entity 1 includes:

[0059] Drive component 11 is installed inside the main body 1;

[0060] Feeding component 12 is installed on top of drive component 11.

[0061] The movable mechanism 2 includes a spring ring 201 installed inside the main body 1, and the movable mechanism 2 also includes:

[0062] Connection component 21 is mounted on top of spring ring 201;

[0063] Expansion component 22 is installed on the side wall of connection component 21.

[0064] The auxiliary mechanism 3 includes a connecting ear 301 disposed inside the feeding assembly 12, and the auxiliary mechanism 3 also includes:

[0065] Rotating assembly 31 is mounted on the side wall of connecting ear 301.

[0066] The drive assembly 11 includes a motor 111 fixedly connected inside the main body 1, and a feed pipe 112 fixedly connected to the side wall of the main body 1;

[0067] Feeding assembly 12 includes a feeding bin 121 bolted to the output end of motor 111, and three feeding pipes 122 bolted to the outer surface of the feeding bin 121.

[0068] The top inner wall of the feeding bin 121 is fixedly connected to an auger 123. When the motor 111 is working, it will drive the feeding pipe 122 and the three feeding pipes 122 on the surface of the feeding pipe 122 to rotate rapidly.

[0069] The elastic end at the bottom of the spring ring 201 is fixedly connected to the bottom inner wall of the main body 1;

[0070] The connecting assembly 21 includes three rubber shafts 211 fixedly connected to the top of the spring ring 201, with one end of the rubber shaft 211 away from the spring ring 201 located inside the feeding tube 122;

[0071] A fixed sleeve 212 is fixedly connected to the outer surface of the rubber shaft 211. Several spiral grooves are opened on the outer surface of the fixed sleeve 212. When the rubber shaft 211 in the feeding tube 122 is pulled, it will drive the spring ring 201 to slide upward and stretch the spring at the bottom of the spring ring 201.

[0072] Three inclined rods are fixedly connected to the end of the rubber shaft 211 away from the spring ring 201. A fixed ring 213 is fixedly connected to the end of the three inclined rods away from the rubber shaft 211. A spring telescopic rod is fixedly connected to the side of the three inclined rods away from the rubber shaft 211.

[0073] The expansion assembly 22 includes a sliding ring 221 that is slidably connected to the outer surface of the fixed sleeve 212. Several insert rods are fixedly connected to the inner wall of the sliding ring 221, and the insert rods are slidably connected inside the spiral groove.

[0074] A plurality of arc-shaped plates 222 are slidably connected to the outer surface of the sliding ring 221, and a rotating ring 223 is rotatably connected to one end of the plurality of arc-shaped plates 222 away from the sliding ring 221;

[0075] The rotating ring 223 is rotatably connected to the outer surface of the rubber shaft 211, and the sliding ring 221 is fixedly connected to the side of the rotating ring 223 with a tripod 224, which slides through the side wall of the rotating ring 223.

[0076] The side wall of the tripod 224 is fixedly connected to the side wall of the spring telescopic rod. When the sliding ring 221 slides, the outer surface of the sliding ring 221 slides on the inner wall of the multiple arc plates 222. Since the side wall of the arc plate 222 has a certain inclined arc, when the sliding ring 221 slides, it will push the arc plate 222 to rotate and expand outward.

[0077] The connecting ear 301 is rotatably connected to the side wall of the fixing ring 213, and the side wall of the fixing ring 213 is fixedly connected to the inclined plate 1.

[0078] The rotating assembly 31 includes a fixing ring 311 fixedly connected to the side wall of the connecting ear 301. Several triangular plates 312 are rotatably connected to the outer surface of the fixing ring 311. An inclined plate 2 is fixedly connected to the side wall of the triangular plate 312.

[0079] A spring plate 313 is provided on the side of the triangular plate 312 near the fixing ring 213, and several spring plates 313 are fixedly connected to the side wall of the fixing ring 311.

[0080] Among them, the elastic end of the spring plate 313 is fixedly connected to the side wall of the triangular plate 312. When the fixed ring 213 slides back to its original position, the inclined plate on the connecting ear 301 will be blocked by the small-diameter inner wall of the feeding tube 122.

[0081] A fixing plate 314 is fixedly connected to the side wall of fixing ring 211, and an auxiliary spring is fixedly connected to the side wall of fixing plate 314. The end of the auxiliary spring away from fixing ring 211 is fixedly connected to the side wall of fixing ring 1213.

[0082] Among them, a spiral shaft 302 is provided on the outer surface of several arc-shaped plates 222, and a limit plate is slidably connected to the side wall of the spiral shaft 302. The limit plate is fixedly connected to the side wall of the rubber shaft 211.

[0083] The end of the spiral shaft 302 away from the sliding ring 221 is fixedly connected to the side wall of the fixing plate 314. The side wall of the fixing plate 314 is in contact with the side wall of the tripod 224. At this time, the expanded arc plate 222 will push the spiral shaft 302 through the inclined surface of its surface, causing the rear end fixing ring 213 of the spiral shaft 302 to slide in the direction of the inclined surface.

[0084] In use, firstly, connect the storage bin 4 to the feed pipe 112 via the feed conveying pipe. The storage bin 4 has an internal electric conveying device. Simultaneously, connect the feed pipe 122 to the feed bin 121 via bolts. Then, place the main body 1 into the breeding pond and secure it with a rod and rope. Next, pour the mixed feed into the storage bin 4. Then, start the storage bin 4 and the motor 111. When the storage bin 4 is working, the conveying device inside the storage bin 4 will transport the feed inside the storage bin 4 to the main body 1 through the conveying pipe. Meanwhile, when the motor 111 is working, it will drive the feeding pipe 122 and the three feeding pipes 122 on the surface of the feeding pipe 122 to rotate rapidly. When the feeding bin 121 rotates, it will drive the internal auger 123 to rotate. When the auger 123 rotates, it will transport the feed inside the main body 1 into the feeding pipe 122. At the same time, when the feeding bin 121 and the three feeding pipes 122 are rotating rapidly, the rapid rotation of the feeding pipe 122 will feed the feed into the breeding pond through the centrifugal force of the rotation, thereby achieving the purpose of feeding.

[0085] Because the multiple triangular plates 312 inside the fixing ring 311 of the feeding pipe 122 are closed, when the auger 123 rotates to convey the bait into the feeding pipe 122, the material will push the multiple triangular plates 312 during the conveying process. At this time, the inclined plates 2 on the multiple triangular plates 312 will be blocked by the inner wall of the feeding pipe 122, and the multiple triangular plates 312 will not open. The continuous conveying of the material will drive the fixing ring 213 and the rubber shaft 2 through the closed multiple triangular plates 312. 11 slides within the feeding tube 122. At this time, the rubber shaft 211 inside the feeding tube 122 is pulled, causing the spring ring 201 to slide upwards and stretch the spring at the bottom of the spring ring 201. Then, when the fixing ring 311 slides to the large-diameter range at the front end of the feeding tube 122, the fixing ring 311 will rotate under the force of the released elastic potential energy of the auxiliary spring, causing the connecting ear 301 to rotate. Simultaneously, the triangular plate 312 will also rotate under the action of the released elastic potential energy of the spring on the spring plate 313, presenting... Figure 9As shown in the diagram, when the material conveyed in the feeding pipe 122 is fed into the aquaculture pond under the action of centrifugal force, some of the material will be thrown far away by the centrifugal force of the high-speed rotating feeding pipe 122 between the fixed ring 213 and the fixed ring 311. Then, some of the material will impact the side wall of the fixed ring 311. When the fixed ring 311 is impacted by the material, it will stretch the auxiliary spring and swing back and forth under the elasticity of the auxiliary spring. The swinging of the fixed ring 311 will periodically block the spilled material and reduce the spilling speed of this part of the material, making it difficult for this part of the material to obtain enough centrifugal force to scatter near the feeding pipe 122. This can improve the uniformity and coverage of the feed during the feeding process, reduce the occurrence of blank feeding circles around the feeding pipe 122 during the feeding process, and improve the feeding efficiency.

[0086] When the fixed ring 311 rotates under the force of the release of the elastic potential energy of the auxiliary spring, the side wall of the fixed plate 314 will separate from the side wall of the tripod 224. At this time, the tripod 224 will slide towards the fixed ring 311 under the push of the spring extension rod. When the tripod 224 slides, it will drive the sliding ring 221 to slide. When the sliding ring 221 slides, its outer surface will slide on the inner wall of the multiple arc plates 222. Since the side wall of the arc plate 222 has a certain inclined arc, when the sliding ring 221 slides, it will push the arc plate 222 to rotate and expand outward. At the same time, when the sliding ring 221 slides, the insert rod on the inner wall of the sliding ring 221 will slide in the spiral groove on the outer surface of the fixed sleeve 212. At this time, the sliding ring 221 will drive the multiple arc plates 222 to slide outward along the spiral groove through the insert rod. When the plate 222 rotates, and multiple arc-shaped plates 222 expand outward, they can push the material conveyed in the feeding pipe 122. At the same time, when the fixed ring 311 rotates outward and is reset and shaken under the tension of the auxiliary spring, the fixed ring 311 will push the tripod 224 through the fixed plate 314. At this time, the tripod 224 will push the sliding ring 221 to reset after being pushed. In this way, when the material continues to be conveyed, the arc-shaped plate 222 can rotate back and forth inside the material and generate a stirring force on the material. By stirring the material, the accumulation and blockage of some material in the feeding pipe 122 due to its own wet and sticky properties can be reduced at the outlet end of the feeding pipe 122 due to the reduced spillage speed. This improves the continuity of material feeding and also improves the stability of the feeding process.

[0087] When the fixed ring 311 rotates under the elasticity of the auxiliary spring, it pulls one end of the spiral shaft 302 through the fixed plate 314. Because the outer surface of the spiral shaft 302 is restricted by the limiting plate, when the spiral shaft 302 is pulled, the portion of the spiral shaft 302 located on the outer surface of the multiple arc-shaped plates 222 moves closer to the surface of the arc-shaped plates 222. When the sliding ring 221 slides back and forth on the surface of the fixed sleeve 212, the sliding of the sliding ring 221 slides between the multiple arc-shaped plates 222 and pushes the multiple arc-shaped plates 222 to rotate and expand outwards. Because the surface of the arc-shaped plates 222 has a certain inclined curvature, when the sliding ring 221 pushes the multiple arc-shaped plates 222 to rotate outwards, the multiple arc-shaped plates 222... The rotation of the arc-shaped plates 222 causes the inner wall of the spiral shaft 302 to expand outward. At this time, the expanding arc-shaped plates 222 push the spiral shaft 302 through the inclined surface of its surface, causing the rear end fixing ring 213 of the spiral shaft 302 to slide. When the spiral shaft 302 is sliding, the spiral shaft 302 can drive the material pushed by the arc-shaped plates 222 to flow when the arc-shaped plates 222 rotate and expand outward. At this time, the material can be less over-push by the arc-shaped plates 222 under the drive of the spiral shaft 302, thereby reducing the excessive crushing of the material when the multiple arc-shaped plates 222 expand and rotate outward, thus improving the integrity of the material particles during feeding, and further improving the uniformity and feeding efficiency.

[0088] After feeding is completed into the aquaculture pond, the contraction potential energy of multiple springs at the bottom of the spring ring 201 will cause the spring ring 201 to reset. When the spring ring 201 resets, it will drive the fixed ring 213 to slide and reset within the feeding tube 122 via the rubber shaft 211. When the fixed ring 213 slides and resets, the inclined plate 1 on the connecting ear 301 will be blocked by the small-diameter inner wall of the feeding tube 122, causing the fixed ring 211 to rotate and reset towards the fixed ring 213. At the same time, the inclined plates 2 on the multiple triangular plates 312 will also reset under the obstruction of the small-diameter inner wall of the feeding tube 122. At this time, the multiple triangular plates 312 will rotate closer to each other. Simultaneously, when the spring ring 201 pulls the fixed ring 213 through the rubber shaft 211 to slide and reset it, the fixed ring 213 will slide and clean the inner wall of the feeding tube 122 during the reset process. Cleaning the inner wall of the feeding tube 122 can reduce the situation where material residue is attached to the inner wall of the feeding tube 122 after feeding. It can also reduce the hardening of material after long-term residue in the feeding tube 122, which would affect the flow area of ​​the feeding tube 122 channel. This ensures the stability of the flow area of ​​subsequent materials through the feeding tube 122, and also ensures the cleanliness of the feeding tube 122 after feeding, further improving the feeding efficiency of subsequent feeding.
