Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, and in particular to a drone-based feeding device for fermented feed in aquaculture. Background Technology

[0002] Traditional aquaculture requires regular feeding within a designated area, typically done manually. However, manual scattering or simple mechanical feeding methods struggle to precisely control the distribution area and evenness. Feed tends to concentrate in certain areas, leading to overfeeding in some areas and underfeeding in others. Competition among fish is fierce, resulting in significant individual feeding variations. Furthermore, this leads to substantial feed waste (statistics show a waste rate of 20%-30% or even higher with traditional feeding methods), uneven fish growth (significant size differences), and negatively impacts overall yield and economic benefits.

[0003] To improve feeding efficiency and reduce labor costs, drones are used for automated feeding in large-scale aquaculture.

[0004] However, the following pain points still exist in current aquaculture feeding practices:

[0005] Manual rowing for feeding is inefficient and can easily disturb the aquaculture water during the feeding process; secondly, fermented powder is prone to moisture absorption and clumping, resulting in uneven feeding when the drone is used for scattering later; crushed corn and other pellet feeds can easily clog the drone's feeding pipes, and existing feeding equipment is not compatible with different types of materials. Utility Model Content

[0006] To address the technical problems of uneven feeding and incompatible materials in existing artificial and drone-based aquaculture feeding methods, this utility model provides a drone-based fermented feed feeding device for aquaculture.

[0007] This utility model is achieved by the following technical solution: a drone feeding device for fermented feed for aquaculture, including a feed cylinder and a conical feed hopper installed at the top and bottom, the feed cylinder and the conical feed hopper forming a feed hopper, a sealing cap is threaded to the top of the feed cylinder, a sealing rubber ring is provided at the connection between the two, a bracket is fixedly connected to the outer wall of the feed cylinder, and multiple connecting arms are evenly fixedly connected to the top of the bracket, the multiple connecting arms are connected to the drone by bolts, a conveying mechanism is coaxially arranged in the feed hopper, and a spraying mechanism is connected to the upper part of the conveying mechanism;

[0008] The conveying mechanism is used to agitate and transport the feed in the silo to the spraying mechanism, and the spraying mechanism sprays the feed to the outside.

[0009] As a further improvement to the above solution, the conveying mechanism includes a conveying cylinder fixedly connected to the inner wall of the conical silo. A circular hole is coaxially opened at the top of the conveying cylinder. A protrusion is fixedly connected to the inner side of the circular hole. A rotating shaft is slidably connected inside the circular hole. An auger blade is coaxially fixedly connected to the rotating shaft. The auger blade moves inside the conveying cylinder.

[0010] As a further improvement to the above solution, a spiral groove is provided on the upper part of the outer wall of the shaft. The spiral groove is slidably connected to the protrusion for synchronous vertical reciprocating sliding during the rotation of the shaft. A slot is provided at the middle of the top of the shaft.

[0012] As a further improvement to the above solution, the spraying mechanism includes a three-way pipe connected to the upper part of the outer wall of the conveying cylinder. One end of the three-way pipe is located outside the feed cylinder and is rotatably connected to a nozzle. The top end of the three-way pipe is connected to a screw motor, which is used to convey the feed to the three-way pipe and spray it along the nozzle through the screw motor.

[0013] As a further improvement to the above solution, an S-shaped guide block is fixedly connected to the inside of the nozzle. The guide block has a ramp on one side in the same direction of rotation. When the screw motor sprays the feed along the nozzle, it will drive the entire nozzle to rotate automatically after contacting the ramp.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Example:

[0025] Please combine Figures 1-5 This embodiment of a fermented feed drone feeding device for aquaculture includes a feed cylinder 1 and a conical feed hopper 4 installed vertically. The feed cylinder 1 and the conical feed hopper 4 form a feed hopper. The top of the feed cylinder 1 is threaded with a sealing cap 5, and a sealing rubber ring is provided at the connection between the two. A bracket 2 is fixedly connected to the outer wall of the feed cylinder 1. Multiple connecting arms 3 are evenly fixedly connected to the top of the bracket 2. The multiple connecting arms 3 are connected to the drone by bolts. A conveying mechanism is coaxially provided in the feed hopper, and a spraying mechanism is connected to the upper part of the conveying mechanism.

[0026] The conveying mechanism is used to agitate and transport the feed in the silo to the spraying mechanism, and the spraying mechanism sprays the feed to the outside.

[0027] Specifically, the longitudinal section α of the conical hopper 4 is ≥60°, and the overall dimensions of the cylinder 1 are 200mm in diameter × 250mm in height → volume ≈7.85L (actual effective volume 6L).

[0028] The conveying mechanism includes a conveying cylinder 6 fixedly connected to the inner wall of the conical silo 4. A circular hole is coaxially opened at the top of the conveying cylinder 6. A protrusion 11 is fixedly connected to the inner side of the circular hole. A rotating shaft 7 is slidably connected inside the circular hole. An auger blade 8 is coaxially fixedly connected to the rotating shaft 7. The auger blade 8 moves inside the conveying cylinder 6.

[0029] The upper part of the outer wall of the rotating shaft 7 is provided with a spiral groove 10, which is slidably connected to the protrusion 11 for synchronous vertical reciprocating sliding during the rotation of the rotating shaft 7. The top center of the rotating shaft 7 is provided with a slot 9.

[0030] Specifically, the spiral groove 10 consists of two symmetrical semicircular grooves connected together.

[0031] A connecting plate 12 is fixedly connected to the top of the conveying cylinder 6, and an agitator motor 13 is fixedly connected to the top of the connecting plate 12. An insert block 14 is fixedly connected to the bottom output shaft of the agitator motor 13, and the insert block 14 is inserted into the slot 9.

[0032] Specifically, during installation, the plug 14 can be directly inserted into the slot 9, and after the slot 9 and the plug 14 are fully inserted, there is still room for movement between the bottom of the slot 9 and the bottom of the plug 14.

[0033] The spraying mechanism includes a three-way pipe 15 connected to the upper part of the outer wall of the conveying cylinder 6. One end of the three-way pipe 15 is located outside the feed cylinder 1 and is rotatably connected to a nozzle 17. The top end of the three-way pipe 15 is connected to a screw motor 16, which is used to convey feed to the three-way pipe 15 and spray it through the nozzle 17 via the screw motor 16.

[0034] An S-shaped guide block 18 is fixedly connected to the inside of the nozzle 17. A ramp 19 is provided on one side of the guide block 18 in the same direction of rotation. When the screw motor 16 sprays the feed along the nozzle 17, it will drive the entire nozzle 17 to rotate automatically after contacting the ramp 19.

[0035] Specifically, as the spraying proceeds, the nozzle 17 will rotate, causing the clogging area of ​​the nozzle 17 to rotate as well. Under the influence of gravity, the clogging area will shift at the orifice, and finally, in conjunction with the spraying power of the spiral motor 16, the clogging of the nozzle 17 can be effectively prevented.

[0036] Furthermore, the internal motors are all encased in waterproof shells, achieving an IP54 protection rating.

[0037] The implementation principle of the unmanned aerial vehicle (UAV) feeding device for fermented feed in aquaculture in this embodiment is as follows:

[0038] Rotate the sealing cover 5, which is threaded to the feed cylinder 1, and place the feed to be fed into the conical hopper 4. The feed will gradually fall into the conical hopper 4 under the action of gravity. After filling, reconnect the sealing cover 5 to the feed cylinder 1 to seal it. Then connect it to the bottom bracket of the drone through the connecting arm 3 and fix it with bolts to realize the connection between the device and the drone.

[0039] The drone is started by the controller, which drives the entire feed hopper 1 to move. The stirring motor 13 is started and connected to the slot 9 by the plug 14, thereby driving the entire rotating shaft 7 to rotate the auger blades 8. The feed deposited at the bottom of the conical hopper 4 is gradually transported to the three-way pipe 15 by the auger blades 8, waiting for the spiral motor 16 to spray the feed.

[0040] As the shaft 7 rotates, the sliding connection between the spiral groove 10 and the protrusion 11 allows the entire shaft 7 to move vertically back and forth synchronously. This enables the auger blades 8 to vibrate while conveying feed, effectively preventing feed blockage.

[0041] Once the feed is delivered to the three-way pipe 15, the screw motor 16 can be started to spray the feed outward along the nozzle 17. As the feed is blown by the screw motor 16 and comes into contact with the ramp 19, the entire nozzle 17 can be pushed to rotate along the outer end connection of the three-way pipe 15.

[0042] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
