Description

Technical Field

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

[0002] Suspended aquaculture feeding device is an automated device used in aquaculture, mainly used to provide feed for aquaculture organisms suspended in water. The device is usually installed in aquaculture ponds, cages or open waters, and can feed regularly, quantitatively and evenly to ensure that aquaculture organisms obtain sufficient nutrition while reducing 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 feed feeding device for aquatic product farming, which belongs to the field of aquaculture technology. It uses the balanced floating effect of the floating plate and the floating ball to effectively expand the feeding range, and can carry out multi-point distributed feeding. At the same time, it can realize the timed and quantitative feeding of bait. The bait falls into the feeding tube and is dispersed by the dividing 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 floating 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, which makes it easier for fish to eat. In addition, an indicator light is installed on the float. When feeding at night, the indicator light is turned on, which effectively increases 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 the bait. Summary of the invention

[0033] As the rotating plate 138 rotates, the push rod 145 is driven to rotate. The push rod 145 rotates to contact and push the inclined surface block 146 to start moving downward. The inclined surface 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 the filter holes from being blocked by bait residues or impurities, thereby ensuring that the bait passes smoothly, maintaining the normal operation of the equipment, avoiding fluctuations in feeding amount caused by 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 1410 to start moving. The movement of the inclined block 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.
