Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, and in particular to a suspended aquaculture feeding device. Background Art

[0002] A suspended aquaculture feeding system is an automated device used in aquaculture, primarily for providing feed to aquaculture organisms suspended in water. Typically installed in aquaculture ponds, cages, or open water, the system delivers feed in a timely, quantitative, and even manner, ensuring adequate nutrition for aquacultured organisms while minimizing feed waste and water pollution.

[0003] The patent with patent announcement number CN211510266U relates to the field of aquaculture technology. The patent discloses a floating bait feeding device for aquaculture, which belongs to the field of aquaculture technology. It includes utilizing the balanced floating effect of the float plate and the float ball to effectively expand the feeding range, and can carry out multi-point distributed feeding. At the same time, it can realize timed and quantitative bait delivery. The bait falls into the feeding tube and is dispersed by the distribution plate. Part of the bait diffuses out through the hollow part at the bottom end of the feeding tube, and the other part of the bait adheres to the bait attachment mechanism during the sinking process. This feeding method can make the bait more evenly distributed around the bottom of the feeding device, which is easy for fish to eat. In addition, a display light is installed on the float ball. When feeding at night, the display light is turned on, which effectively increases the light intensity of the environment in which the device is located, which is beneficial to attract fish to gather and feed to a certain extent, thereby effectively improving the feeding efficiency.

[0004] In the above patent, the bait is distributed more evenly around the bottom of the feeding device, making it easier for fish to eat. In addition, a display light is installed on the float. When feeding at night, the display light is turned on, effectively increasing the light intensity in the environment where the device is located, which is helpful to attract fish to gather and feed to a certain extent, thereby effectively improving the feeding efficiency. However, it is difficult to push the bait out when discharging the bait, which can easily lead to difficulty in discharging the bait or excessive accumulation of bait. Summary of the Invention

[0017] (1) This invention continuously paddles the bait inside the food storage tank by rotating a fixed plate. The bait is paddled through the bottom of the equipment and enters the water below, ensuring that all cultured organisms can obtain sufficient nutrition, promoting balanced growth, reducing individual differences, avoiding local overfeeding or insufficient bait, and ensuring stable and uniform discharge of bait, reducing equipment blockage or failure, improving the reliability of automatic feeding, and reducing the need for human intervention.

[0018] (2) This invention can push the bait evenly through the push plate, so that it is widely distributed in the breeding area, avoiding the concentration of bait, ensuring that all breeding organisms can ingest feed, and promoting balanced growth. At the same time, the push plate design is suitable for baits in different forms such as granules and powders, and has strong versatility.

[0019] (3) This invention can precisely control the amount of feed fed each time through the coordinated work of the upper sliding door and the lower sliding door, avoiding overfeeding or underfeeding, ensuring that the farmed organisms receive the right amount of feed and reducing waste. At the same time, precise control of the feeding amount facilitates monitoring of feed consumption and the growth of farmed organisms, helping to optimize feeding strategies and improve management efficiency.

[0020] (4) This invention, by rotating the rotating plate, quickly throws the bait into the breeding area when the bait is discharged, ensuring that the bait is evenly dispersed, avoiding local excessive concentration or insufficient bait, and promoting balanced feeding of the breeding organisms. At the same time, in a high-density breeding environment, the rotating plate quickly spreads the bait to ensure that all breeding organisms can obtain feed in a timely manner, avoiding uneven growth caused by competition.

[0021] (5) This invention uses a scraper ring to move and clean the filter plate to prevent bait residue or impurities from clogging the filter holes, ensuring smooth passage of bait, maintaining normal operation of the equipment, avoiding fluctuations in feeding amount due to blockage, and improving feeding accuracy. The guard plate moves during feeding to prevent the farmed organisms from excessively impacting the equipment when scrambling for food, causing damage to the equipment or harm to the farmed organisms. At the same time, it prevents impurities from the bottom from entering the equipment, avoiding blockage or damage, improving equipment operation reliability, and reducing the risk of downtime.

[0043] When the upper and lower gates 132 are in contact with each other, the upper and lower gates 133 are in contact with each other, and the lower and lower gates 135 are in contact with each other, so that the upper and lower gates 132 are in contact with each other, and the upper and lower gates 133 are in contact with each other, so that the upper and lower gates 132 are in contact with each other, and the upper and lower gates 133 are in contact with each other, and the upper and lower gates 135 are in contact with each other, so that the upper and lower gates 132 are in contact with each other, and the upper and lower gates 133 are in contact with each other, so that the upper and lower gates 132 are in contact with each other, and the upper and lower gates 135 are in contact with each other, so that the upper and lower gates 132 are in contact with each other, and the upper and lower gates 133 are in contact with each other, The growth of the aquatic organisms is monitored to help optimize the feeding strategy and improve management efficiency. When the positioning rod 133 moves downward, it drives the upper sliding door 132 to start moving downward. The movement of the upper sliding door 132 drives the lower sliding door 135 to start moving downward. At this time, the bait moves downward through movement and contacts the water flow in the water area and diffuses. When the lower sliding door 135 rotates and starts to move downward, it drives the gear 136 to start rotating and moving downward. The gear 136 moves downward and engages with the gear 2 139. The rotation of the gear 136 drives the gear 2 139 to rotate. The rotation of the gear 2 139 drives the rotating plate 138 to start rotating around the rotating rod 137. The rotating plate 138 rotates to quickly throw the bait into the breeding area when the bait is discharged, ensuring that the bait is evenly dispersed, avoiding local excessive concentration or deficiency, and promoting balanced feeding of the aquatic organisms. At the same time, in a high-density breeding environment, the rotating plate 138 quickly spreads the bait to ensure that all aquatic organisms can obtain feed in time, avoiding uneven growth caused by competition.

[0044] As the rotating plate 138 rotates, the push rod 145 is driven to start rotating. The push rod 145 rotates to contact and push the inclined block 146 to start moving downward. The inclined block 146 moves to drive the top rod 143 to start moving downward. The top rod 143 moves to drive the scraper ring 144 to start moving. The scraper ring 144 moves to clean the filter plate 1310 to prevent bait residue or impurities from clogging the filter holes, ensuring that the bait passes smoothly, maintaining the normal operation of the equipment, avoiding fluctuations in feeding amount due to blockage, and improving feeding accuracy. At the same time, the scraper ring 144 automatically cleans and lifts the equipment The degree of automation reduces manual intervention and improves management efficiency. When the scraper ring 144 moves, the inclined rod 147 is driven to move. The inclined rod 147 moves to contact and push the inclined block 2 1410 to start moving. The movement of the inclined block 2 1410 drives the guard plate 149 to start moving. The movement of the guard plate 149 prevents the farmed organisms from excessively impacting the equipment when scrambling for food during feeding, causing damage to the equipment or harm to the farmed organisms. At the same time, it prevents impurities at the bottom from entering the equipment, avoiding blockage or damage, improving equipment operation reliability, and reducing the risk of downtime.
