Abstract
Description
Technical Field
[0001] This utility model relates to an automatic feeding mechanism for aquaculture using unmanned aerial vehicles (UAVs), belonging to the field of aquaculture technology. Background Technology
[0002] Aquaculture is the practice of raising aquatic economic animals using available waters, according to the ecological habits and environmental requirements of the aquatic species, and employing aquaculture techniques and facilities. During aquaculture, regular feeding of the aquaculture area is necessary. Manual feeding is inefficient, costly, and difficult to achieve precise feeding.
[0003] The application of drones in aquaculture feeding represents a significant innovation in modern smart fisheries. By precisely controlling feed volume and covering large water areas, it significantly improves aquaculture efficiency and management. There is an urgent need to design a feeding mechanism for use on drones. Utility Model Content
[0004] The purpose of this invention is to solve the technical problems of low efficiency and difficulty in accurate feeding in the existing technology of manual feeding, and to provide an automatic feeding mechanism for aquaculture using drones.
[0005] This utility model is achieved through the following technical solution:
[0006] An automatic feeding mechanism for aquaculture using a drone includes a feed box installed inside the drone body. The feed box has a discharge port at the bottom, and an electric valve is installed on the discharge port. A lower support plate is installed below the drone body, and the discharge port passes through the lower support plate. A fixed cylinder is fixed on the bottom surface of the lower support plate, and a rotatable rotating cylinder is located at the lower part of the fixed cylinder. Two guide plates are fixed at the lower part of the rotating cylinder, and several discharge holes are evenly opened at the lower part of the rotating cylinder. Several sets of arc-shaped guide troughs are fixed between the two guide plates. Each set of arc-shaped guide troughs includes two plates, and each set of arc-shaped guide troughs and the discharge holes form an arc-shaped guide channel.
[0007] Feed is loaded into the feed hopper, and the electric valve is opened remotely. The feed falls from the outlet into both the fixed and rotating cylinders. Simultaneously, the rotating cylinder begins to rotate, and two guide plates rotate together. Under the action of centrifugal force, the feed inside the rotating cylinder is discharged through the discharge hole. Guided by the arc-shaped guide channels, the feed is thrown out in an arc shape during the drone's flight. This method offers high feeding efficiency, and results in more uniform and precise feeding on the water surface.
[0008] In a further optimized design, a wear-resistant ring is provided between the lower part of the fixed cylinder and the upper part of the rotating cylinder. The upper part of the rotating cylinder has an inwardly flanged structure, with the inwardly flanged edge clamping onto the wear-resistant ring. A gear ring is fixedly mounted on the outer side of the upper part of the rotating cylinder, and a motor is mounted on the lower support plate. The motor is connected to the gear ring via a gear on the main shaft. The motor drives the rotating cylinder to rotate through the gear and gear ring transmission mechanism. The wear-resistant ring, as a replaceable wear-resistant component, prevents direct contact between the fixed cylinder and the rotating cylinder, thus providing excellent protection.
[0009] Further optimization involves using a split structure for the wear-resistant ring, which is mounted on the lower part of the fixed cylinder with screws. This facilitates replacement and allows for individual replacement of each piece, reducing costs.
[0010] Further optimization involves the discharge holes being evenly distributed in a ring at intervals at the bottom of the rotating cylinder.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] Feed is loaded into the feed hopper, and the electric valve is opened remotely. The feed falls from the outlet into both the fixed and rotating cylinders. Simultaneously, the rotating cylinder begins to rotate, and two guide plates rotate together. Under the action of centrifugal force, the feed inside the rotating cylinder is discharged through the discharge hole. Guided by the arc-shaped guide channels, the feed is thrown out in an arc shape during the drone's flight. This method offers high feeding efficiency, and results in more uniform and precise feeding on the water surface. Attached Figure Description

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0020] like Figures 1 to 4 The above describes an automatic feeding mechanism for aquaculture using a drone, comprising a feed bin 2 installed inside the drone body 1. The feed bin 2 has a cover plate 4 at the top and a discharge port 5 at the bottom. An electric valve 6 is installed on the discharge port 5. A lower support plate 3 is installed below the drone body 1. The discharge port 5 passes through the lower support plate 3. A fixed cylinder 7 is fixedly installed on the bottom surface of the lower support plate 3. A rotatable rotating cylinder 8 is installed at the bottom of the fixed cylinder 7. Two guide plates 13 are fixedly installed at the bottom of the rotating cylinder 8. Several discharge holes 14 are evenly opened at the bottom of the rotating cylinder 8. Several sets of arc-shaped guide troughs 15 are fixedly installed between the two guide plates 13. Each set of arc-shaped guide troughs 15 includes two plates. Each set of arc-shaped guide troughs 15 and the discharge holes 14 form an arc-shaped guide channel.
[0021] Feed is loaded into the feed hopper 2, and the electric valve 6 is opened remotely. The feed falls from the outlet 5 into the fixed cylinder 7 and the rotating cylinder 8. At the same time, the rotating cylinder 8 begins to rotate, and the two guide plates 13 rotate together. Under the action of centrifugal force, the feed in the rotating cylinder 8 is discharged from the outlet 14. Guided by the arc-shaped guide channels, the feed is thrown out in an arc shape during the drone's flight. The feeding efficiency is high, and the feed is more uniform and accurate when fed on the water surface.
[0022] A wear-resistant ring 9 is provided between the lower part of the fixed cylinder 7 and the upper part of the rotating cylinder 8. The upper part of the rotating cylinder 8 has an inwardly flanged structure, which is engaged with the wear-resistant ring 9. A gear ring 10 is fixedly mounted on the upper part of the rotating cylinder 8. A motor 11 is mounted on the lower support plate 3. The motor 11 is connected to the gear ring 10 through a gear 12 on the main shaft. The motor 11 drives the rotating cylinder 8 to rotate through the gear 12 and gear ring 10 transmission mechanism. The wear-resistant ring 9, as a wear-resistant and replaceable part, avoids direct contact between the fixed cylinder 7 and the rotating cylinder 8, thus providing good protection.
[0023] The wear-resistant ring 9 adopts a split structure and is installed on the lower part of the fixed cylinder 7 with screws. This facilitates replacement and allows for individual replacement of each piece, reducing costs.
[0024] Among them, the discharge holes 14 are evenly distributed in a ring at intervals at the lower part of the rotating cylinder 8, which helps to improve the uniformity of feeding on the water surface.
[0025] The feed guide plate 13 at the bottom has a feeding protrusion 16 at its center. The feed falls from the outlet 5 and is evenly distributed at multiple outlet holes 14, which improves the uniformity of feeding on the water surface.
[0026] Working principle:
[0027] Feed is loaded into the feed hopper 2, and the electric valve 6 is opened remotely. The feed falls from the outlet 5 into the fixed cylinder 7 and the rotating cylinder 8. At the same time, the motor 11 drives the rotating cylinder 8 to rotate through the gear 12 and gear ring 10 transmission mechanism. The two guide plates 13 rotate together, and the feed in the rotating cylinder 8 is discharged from the outlet 14 under the action of centrifugal force. Guided by the arc-shaped guide channels, the feed is thrown out in an arc shape during the flight of the drone. The feeding efficiency is high, and the feed is more uniform and accurate when fed on the water surface.
