Description

Technical Field

[0001] This invention relates to the field of aquaculture equipment technology, specifically to a feeding device and its usage method for experimental net cage aquaculture. Background Technology

[0002] Cage aquaculture is one of the mainstream models for large-scale aquaculture in nearshore and inland waters. Experimental cages are core facilities for scientific research such as aquaculture breeding, aquaculture technology research, and feed formulation experiments. Feeding operations in experimental cages require not only timely and quantitative feeding, but also ensuring even distribution of feed and full coverage of the feeding area to guarantee the accuracy of experimental data and the normal feeding of aquatic organisms. At present, most experimental cage aquaculture uses simple fixed-point feeding equipment to complete the feeding work. The conventional fixed feeding equipment on the market has a simple structure and a single feeding method. It can only realize fixed-point feeding, and the feeding area is limited, which cannot meet the feeding needs of large experimental cages. At the same time, the equipment lacks an automatic feeding structure, requiring staff to frequently climb up the cages to add feed, resulting in low work efficiency. Therefore, a feeding device and its usage method for experimental cage aquaculture are proposed. Summary of the Invention

[0003] In order to solve the technical problems existing in the prior art, the present invention provides a feeding device for experimental cage aquaculture.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a feeding device for experimental cage aquaculture, comprising a feeding module, a supplementary feeding module, and an energy supplementation module; The feeding module is used to deliver feed; The feeding module is installed at the bottom of the feeding module and is used to provide feed to the feeding module. The energy replenishment module is installed on top of the feeding module and is used to provide electrical energy to the feeding module.

[0005] Preferably, the feeding module includes an outer sleeve, a feeding module, a main hopper, and a pneumatic spraying module. The interior of the outer sleeve is divided into upper and lower layers by a partition. The feeding module is located in the middle of the partition inside the outer sleeve. The main hopper is installed on top of the feeding module and feeds the feed from the main hopper. The pneumatic spraying module is located on the side of the partition inside the outer sleeve and is connected to the feeding module. The pneumatic spraying module sprays the feed fed by the feeding module.

[0006] Preferably, the feeding module includes a screw feeder, a servo motor, and a mixing pipe. The screw feeder is installed at the center of the partition, the servo motor is installed at the end of the screw feeder, the output end of the servo motor is connected to the main shaft of the screw feeder, and the mixing pipe is installed at the discharge port of the screw feeder. The feed output by the screw feeder is sent out through the mixing pipe.

[0007] Preferably, the pneumatic spraying module includes a blower, an air duct, and a material spraying nozzle. The blower is installed on the side of the partition, the air duct is installed at the output end of the blower and is connected to the mixing pipe, and the material spraying nozzle is installed at the outlet of the air duct.

[0008] Preferably, the outlet end of the spreading nozzle passes through the outer sleeve and extends to the outside of the outer sleeve, and the setting direction of the spreading nozzle is parallel to the tangential direction of the outer sleeve.

[0009] Preferably, the feeding module further includes a battery and a control box, which are located in the lower inner layer of the outer sleeve. The battery is electrically connected to the control box and to the servo motor and blower.

[0010] Preferably, the feeding module includes an auxiliary hopper, a screw conveyor, and a feeding pipe. The auxiliary hopper is installed at the bottom of the outer sleeve, and the screw conveyor and the feeding pipe are arranged in parallel between the auxiliary hopper and the main hopper. The screw conveyor is electrically connected to the battery.

[0011] Preferably, the energy replenishment module includes a main tube and a solar panel assembly. The main tube is installed on the top of the main hopper and extends through the outer sleeve to the outside of the outer sleeve.

[0012] Preferably, the main tube has a side opening door on its side, and the bottom of the main tube corresponds to the feed inlet at the top of the feeding module.

[0013] A feeding device for experimental cage aquaculture and its usage method include the following steps: Step S1: Open the side door on the side of the main feed pipe and feed the livestock feed into the auxiliary feed hopper from inside the main feed pipe. The feed falls into the main feed hopper along the main feed pipe. The feed in the main feed hopper is fed into the auxiliary feed hopper through the feed replenishment pipe.

At the same time, the present invention is equipped with an independent feeding module, which can automatically complete the feeding, eliminating the need for staff to repeatedly climb up the box to manually add feed, greatly reducing the intensity of manual labor and significantly improving the overall efficiency of feeding operations.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, which illustrate the above and other technical features and advantages of the present invention. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive. Example

[0018] like Figures 1-5 As shown, the present invention provides a feeding device for experimental cage aquaculture, including a feeding module 1, a feeding module 2 and an energy replenishment module 3; Feeding module 1 is used to deliver feed; Feeding module 2 is installed at the bottom of feeding module 1 and is used to provide feed to feeding module 1; The power replenishment module 3 is installed on top of the feeding module 1 and is used to provide power to the feeding module 1.

[0019] The feeding module 1 includes an outer sleeve 11, a feeding module 12, a main hopper 13, and a pneumatic spraying module 14. The interior of the outer sleeve 11 is divided into upper and lower layers by a partition. The feeding module 12 is located in the middle of the partition inside the outer sleeve 11. The main hopper 13 is installed on top of the feeding module 12. The feeding module 12 feeds the feed inside the main hopper 13. The pneumatic spraying module 14 is located on the side of the partition inside the outer sleeve 11. The pneumatic spraying module 14 is connected to the feeding module 12 and sprays the feed fed by the feeding module 12.

[0020] The feeding module 12 includes a screw feeder 121, a servo motor 122, and a mixing pipe 123. The screw feeder 121 is installed at the center of the partition, the servo motor 122 is installed at the end of the screw feeder 121, and the output end of the servo motor 122 is connected to the main shaft of the screw feeder 121. The mixing pipe 123 is installed at the discharge port of the screw feeder 121, and the feed output by the screw feeder 121 is sent out through the mixing pipe 123. During operation, the servo motor 122 drives the screw feeder 121 to rotate, and the screw feeder 121 continuously pushes the feed into the mixing pipe 123 during the rotation process.

[0021] The pneumatic spraying module 14 includes a blower 141, an air duct 142, and a spreading nozzle 143. The blower 141 is installed on the side of the partition, the air duct 142 is installed at the output end of the blower 141 and is connected to the mixing pipe 123, and the spreading nozzle 143 is installed at the outlet of the air duct 142. When the servo motor 122 is working, the blower 141 works synchronously. The blower 141 continuously blows high-speed airflow into the air duct 142. The high-speed airflow in the air duct 142 blows the feed delivered by the mixing pipe 123 into the spreading nozzle 143 and sprays it out from the spreading nozzle 143.

[0022] The discharge port end of the spreading nozzle 143 passes through the outer sleeve 11 and extends to the outside of the outer sleeve 11. The setting direction of the spreading nozzle 143 is parallel to the tangential direction of the outer sleeve 11. When the spreading nozzle 143 continuously sprays out the feed, it generates a reaction force. The reaction force pushes the outer sleeve 11 to deflect, thereby changing the spraying area of ​​the feed.

[0023] The feeding module 1 also includes a battery 15 and a control box 16. The battery 15 and the control box 16 are located in the lower inner layer of the outer sleeve 11. The battery 15 is electrically connected to the control box 16 and is electrically connected to the servo motor 122 and the blower 141. The battery 15 is used to supply power to the servo motor 122 and the blower 141, and the control box 16 is used to control the working status of the feeding module 12 and the blower 141.

[0024] The feeding module 2 includes an auxiliary hopper 21, a screw conveyor 22, and a feeding pipe 23. The auxiliary hopper 21 is installed at the bottom of the outer sleeve 11. The screw conveyor 22 and the feeding pipe 23 are arranged in parallel between the auxiliary hopper 21 and the main hopper 13. The screw conveyor 22 is electrically connected to the battery 15. When the screw conveyor 22 is working, it can send the feed inside the auxiliary hopper 21 into the feeding module 12. When feeding is added to the main hopper 13, the feed inside the main hopper 13 can be added to the auxiliary hopper 21 through the feeding pipe 23. The feeding module 2 can extend the standby time of the equipment.

[0025] The energy replenishment module 3 includes a main pipe 31 and a solar panel 32. The main pipe 31 is installed on the top of the main hopper 13 and extends through the outer sleeve 11 to the outside of the outer sleeve 11. The solar panel 32 is installed on the top of the main pipe 31 and is electrically connected to the battery 15. The solar panel 32 is used to charge the battery 15. A side door is opened on the side of the main pipe 31. The bottom of the main pipe 31 corresponds to the feed inlet on the top of the feeding module 12. The main pipe 31 can be used as a guide pipe through the side door to guide the supplemented feed into the feeding module 12.

[0026] A feeding device for experimental cage aquaculture and its usage method include the following steps: Step S1: Open the side door on the side of the main pipe 31 and feed the livestock feed into the auxiliary feed hopper 21 from inside the main pipe 31. The feed falls into the main feed hopper 13 along the main pipe 31. The feed in the main feed hopper 13 is fed into the auxiliary feed hopper 21 through the supplementary feed pipe 23. When the feed in the auxiliary feed hopper 21 is full, feed is added to the main feed hopper 13. After the main feed hopper 13 is filled, close the side door of the main pipe 31. In step S2, the operation control box 16 issues a start command, and the battery 15 starts to supply power to the servo motor 122 and the blower 141. The servo motor 122 drives the screw feeder 121 to run continuously, pushing the feed in the main hopper 13 to the mixing pipe 123 at a uniform speed. In step S3, the blower 141 operates to generate a high-speed airflow, which enters the mixing pipe 123 through the air duct 142 and carries the feed along with it to the spreading nozzle 143, from which the feed is sprayed outward. In step S4, the reaction force generated when the feed is sprayed causes the outer sleeve 11 to gradually deflect, and the feed is evenly scattered in various areas of the cage. In step S5, when the feed in the main hopper 13 is exhausted, the control box 16 controls the screw conveyor 22 to work, and the screw conveyor 22 transports the spare feed in the auxiliary hopper 21 to the main hopper 13.
