Description

Technical Field

[0001] The invention relates to the technical field of cage aquaculture, in particular to an underwater feeding device based on marine cage aquaculture. Background Art

[0002] Marine aquaculture is a production activity that utilizes water resources such as the ocean and coastal shallow beaches to cultivate marine aquatic economic plants and animals through artificial breeding. This industry covers a complete industrial chain from the selection of aquaculture species, seedling cultivation, aquaculture management to product processing and sales. There are various ways to classify marine aquaculture, which can be classified from different angles. According to the aquaculture object: it can be divided into fish, shrimp, crab, shellfish, algae and marine delicacies. Generally, fish farming is to place fish in cages for breeding, and fish farming needs to be fed through feeding devices.

[0003] The existing patent number CN111838044B discloses a multifunctional underwater feeding device for marine cage aquaculture, which is suitable for multifunctional underwater feeding of fully floating cages, semi-submerged cages and bottom-sitting cages. It includes a cyclone vortex mixer, a seawater pipeline, a main feeding pipeline and a feed feeding manifold; wherein the cyclone vortex mixer includes a wind-blown feed dispersion bin and a seawater turbine bin; the seawater turbine bin includes a number of seawater inlets and vortex guide plates, and the bottom of the vortex guide plates is connected to the main feeding pipeline; the upper end of each seawater pipeline is connected to the corresponding seawater inlet, and the lower end is connected to a seawater submersible pump immersed in seawater to pump seawater into the seawater turbine bin, forming a rotating downward vortex to drive the feed into the main feeding pipeline; the lower end of the main feeding pipeline is connected to the main feeding pipeline. A plurality of feed feeding manifolds are arranged at the end to feed the feed in the main feeding pipe to the aquaculture water space at multiple points through the feed feeding manifolds. The feeding method in the invention drops the feed feeding manifold to the bottom of the seabed in a suspended manner for feeding. When feeding is required at different heights, the feed feeding manifold is suspended and moved up and down, which is very time-consuming. When feeding, the fish will gather in the area where the feed feeding manifold is located to forage, which will cause crowding among the fish and affect feeding, and the feeding range is small.

The feeding component 220 can be moved to the desired position inside the breeding cage 100 through the cooperation of the mechanical arm 212 and the telescopic rod 213.

[0045] It should be understood that when the robot arm 212 is working, it can drive the feeding assembly 220 to move inside the breeding cage 100 through the telescopic rod 213, and the movement range of the feeding assembly 220 can also be increased through the operation of the telescopic rod 213.

[0047] It is worth noting that the feed pipe 221 can transport the feed to the interior of the upper conveying cylinder 223 through the bellows 222. When the feed enters the interior of the upper conveying cylinder 223, seawater will also enter its interior through the water inlet 228. At the same time, the water pump 227 can generate suction through the conveying pipe 226. The suction of the conveying pipe 226 can transport the seawater and the feed from the upper conveying cylinder 223 to the interior of the lower conveying cylinder 225 through the middle conveying cylinder 224. When the feed enters the interior of the lower conveying cylinder 225, the feed that has not been ejected can be re-transported to the interior of the upper conveying cylinder 223 through the conveying pipe 226 and the water pump 227.

[0048] like Figure 2-Figure 6 As shown, a feeding assembly 230 is installed inside the feed assembly 220, and the feeding assembly 230 also includes a jet head 236 installed between the upper conveying cylinder 223, the middle conveying cylinder 224 and the lower conveying cylinder 225, and a feeding pipe 237 fixed at the end of the jet head 236. When the jet head 236 sprays high-pressure gas, a negative pressure is generated inside the feeding pipe 237 to suck the feed inside the upper conveying cylinder 223, the middle conveying cylinder 224 and the lower conveying cylinder 225 into the feeding pipe 237 and spray it into the inside of the breeding net cage 100 to feed the fish school. An air compressor 231 is installed at the top of the upper conveying cylinder 223. The upper conveying cylinder 223, the middle conveying cylinder 224 and the lower conveying cylinder 225 are connected to the air inlet pipe 233 through the assembly groove. The top of the air inlet pipe 233 is connected to the air compressor 231. The output end of the machine 231 is connected through a connecting pipe 232, and the upper conveying cylinder 223, the middle conveying cylinder 224, the lower conveying cylinder 225 and the air inlet pipe 233 are fixedly connected through a support frame 234.

When the rotating shaft 239 rotates, it can rotate inside the feeding tube 237 and the fixed cylinder 238. When the rotating shaft 239 rotates, it can twist the torsion spring 2310. When the closing plate 2311 is opened, the air can be sprayed into the inside of the breeding cage 100 through the feeding tube 237. While spraying, the air can generate negative pressure inside the feeding tube 237. The negative pressure inside the feeding tube 237 can suck the feed and seawater inside the upper conveying cylinder 223, the middle conveying cylinder 224 and the lower conveying cylinder 225 into the inside, and spray them into the inside of the breeding cage 100.

The rotation of the feeding tube 237 can drive the hopper 255 to rotate. When the hopper 255 rotates, it will rotate and generate suction through the impeller 256. The rotation and self-rotation of the hopper 255 allow the feed to quickly enter the inside of the feeding tube 237. The inner walls of the upper conveying cylinder 223, the middle conveying cylinder 224, and the lower conveying cylinder 225 are all provided with a rotating groove 252, and the rotating groove 252 is fixedly installed inside the hopper 255.
