Description

Technical Field

[0001] This invention relates to a feeding device, specifically a feeding device for marine aquaculture farms. Background Technology

[0002] In the current booming marine aquaculture industry, scientific and efficient feeding methods play a crucial role in ensuring the healthy growth of farmed organisms and improving both yield and quality. However, traditional marine aquaculture feeding methods and equipment have many problems that urgently need to be solved.

[0003] Traditional feeding methods rely heavily on manual operation, which is not only labor-intensive and inefficient but also makes it difficult to accurately control the amount of material fed. Overfeeding leads to feed waste, increases aquaculture costs, and uneaten feed sinks to the seabed, polluting the aquaculture environment. Underfeeding fails to meet the growth needs of the farmed organisms, affecting their growth rate and health. Regarding material mixing, traditional methods often fail to achieve effective and uniform mixing of various materials. Different types of feed have different nutritional compositions; uneven mixing leads to unbalanced nutrient intake by the farmed organisms, affecting their growth performance and immunity. Furthermore, traditional feeding devices have a limited range, making it difficult to cover large aquaculture areas. This results in uneven distribution of food for the farmed organisms, with some areas overfeeding due to abundant food while others suffer from food scarcity and stunted growth, hindering overall aquaculture efficiency. Therefore, a new feeding device for marine aquaculture farms is needed to address this problem. Summary of the Invention

[0004] The purpose of this invention is to provide a feeding device for marine aquaculture farms to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A feeding device for marine aquaculture includes a feeding box, which has an installation cavity and a mixing cavity. A partition is provided between the installation cavity and the mixing cavity, and a plurality of feeding bins are installed on the partition. Each feeding bin has a discharge port on its top wall. A sealing plate is provided at the bottom of the partition, and the sealing plate has the same number of discharge holes as the discharge ports. A conveyor frame is provided at the bottom of the feeding box, and a plurality of conveying troughs are provided on the conveyor frame. Spiral blades are installed in the conveying troughs, and a feed pipe is installed on the top wall of the conveying troughs. One end of the conveying trough is connected to the mixing chamber. A valve is installed on the feed pipe, and a discharge port is provided at the end of the conveying trough away from the feed pipe. A spreading plate is provided at the bottom of the discharge port. A stirring rod is provided in the mixing chamber. A drive assembly is installed on the feeding box. The stirring rod and the sealing plate are both connected to the drive assembly. A transmission assembly and a spreading mechanism are installed on the conveying frame. One end of the transmission assembly is connected to the drive assembly, and the other end is connected to the spiral blade. One end of the spreading mechanism is connected to the drive assembly, and the other end of the spreading mechanism is connected to the spreading plate.

[0007] As a further aspect of the present invention: the driving assembly includes a driving box, which is disposed on the upper side of the feeding box. A driving component is disposed in the driving box, and a driving shaft is installed at the output end of the driving component. The end of the driving shaft away from the driving component passes through the driving box and the feeding box, and the stirring rod is installed on the driving shaft.

[0008] As a further aspect of the present invention: the transmission assembly includes a transmission shaft, which is rotatably connected to the side wall of the conveying trough, and one end of the transmission shaft extends into the conveying trough. The spiral blade is mounted on the transmission shaft, and a connecting unit is mounted on the drive shaft. The end of the connecting unit away from the drive shaft is connected to the transmission shaft.

[0009] As a further aspect of the present invention: the material spreading mechanism includes a material spreading rod, one end of which is rotatably connected to the bottom wall of the conveyor frame, and the other end of which is connected to the material spreading plate. A connecting mechanism is installed on the drive shaft, and the end of the connecting mechanism away from the drive shaft is connected to the driven shaft.

[0010] As a further embodiment of the present invention: the loading bin is provided with a stirring blade, a driven shaft is rotatably connected to the top wall of the feeding box, one end of the driven shaft extends into the loading bin, the stirring blade is installed on the driven shaft, and a transmission unit is installed on the drive shaft, with the end of the transmission unit away from the drive shaft connected to the driven shaft.

[0011] As a further aspect of the present invention: an elastic component is provided on one side of the driven shaft, one end of the elastic component is connected to the top wall of the feeding box, and a bell is installed on the other end of the elastic component. A striking rod is provided on one side of the driven shaft, and one end of the striking rod is fixedly installed on the driven shaft.

[0012] As a further aspect of the present invention, it also includes a fixed steel frame, a reinforcing base installed at the bottom of the fixed steel frame, a reinforcing rod installed on the feeding box, the end of the reinforcing rod away from the feeding box being connected to the fixed steel frame, and a connecting rod installed on the drive box, the end of the connecting rod away from the drive box being connected to the fixed steel frame.

[0013] Compared with existing technologies, the beneficial effects of this invention are as follows: The feeding device moves the sealing plate via a drive shaft, achieving precise alignment between the material discharge hole and the discharge port. This allows for precise control of the amount of various materials entering the mixing chamber, meeting the personalized nutritional needs of different breeding stages and the cultured organisms. Simultaneously, the drive shaft drives the stirring rod to rotate fully within the mixing chamber, efficiently mixing various materials and ensuring a uniform distribution of feed nutrients. This provides the cultured organisms with stable quality and balanced nutrition, contributing to improved growth rate and health. Furthermore, the drive shaft transmits power to the transmission shaft via a connecting unit, causing the spiral blades to rotate stably within the conveying trough, generating reliable axial thrust. This ensures smooth material transport from one end of the conveying trough to the other, avoiding blockages and accumulation during transport. Furthermore, the drive shaft, through a connecting mechanism, rotates the spreading plate, using centrifugal force to evenly distribute the material across the aquaculture area. This expands the feed coverage, allowing farmed organisms to access food over a larger area, improving feed utilization and reducing waste caused by concentrated feed distribution. The drive shaft, via a transmission unit, drives the driven shaft, whose stirring blades continuously agitate the material in the feeding hopper, effectively preventing material accumulation and blockage. This ensures the material smoothly falls from the discharge port into the mixing chamber, guaranteeing the continuity and stability of the feeding process. Additionally, a striking rod, rotating with the driven shaft, strikes a bell. The sound attracts fish to the feeding area, reducing the likelihood of feed sinking to the bottom or being washed away by the water flow due to dispersed distribution. This shortens the feeding time for farmed organisms, reduces the risk of feed dissolution and loss, and significantly lowers aquaculture costs. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1 to 8As an embodiment of the present invention, a feeding device for marine aquaculture includes a feeding box 4, which has an installation cavity and a mixing cavity 13. A partition 12 is provided between the installation cavity and the mixing cavity 13. A plurality of feeding bins 11 are installed on the partition 12. Each feeding bin 11 has a discharge port 25 on its top wall. A sealing plate 26 is provided at the bottom of the partition 12. The sealing plate 26 has the same number of discharge holes 27 as the discharge ports 25. A conveying frame 8 is provided at the bottom of the feeding box 4. A plurality of conveying troughs are provided on the conveying frame 8. Spiral blades 31 are provided in the conveying troughs. A spiral blade 31 is installed on the top wall of the conveying trough. The conveyor is equipped with a feed pipe 7, the end of which is away from the conveying trough and connected to the mixing chamber 13. A valve is installed on the feed pipe 7, and a discharge port 9 is provided at the end of the conveying trough away from the feed pipe 7. A spreading plate 10 is provided at the bottom of the discharge port 9. A stirring rod 14 is provided in the mixing chamber 13. A drive assembly is installed on the feeding box 4. The stirring rod 14 and the sealing plate 26 are connected to the drive assembly. A transmission assembly and a spreading mechanism are installed on the conveying frame 8. One end of the transmission assembly is connected to the drive assembly, and the other end is connected to the spiral blade 31. One end of the spreading mechanism is connected to the drive assembly, and the other end is connected to the spreading plate 10.

[0025] In this embodiment, when material needs to be added to the mixing chamber 13, the drive assembly is activated, driving the sealing plate 26 to move so that the discharge hole 27 aligns with the discharge port 25. At this time, the material in the loading bin 11 can fall into the mixing chamber 13 through the discharge port 25 and the discharge hole 27. By controlling the moving distance and time of the sealing plate 26, the amount of material entering the mixing chamber 13 can be precisely adjusted. A stirring rod 14 is provided in the mixing chamber 13, and the stirring rod 14 is connected to the drive assembly. When the material enters the mixing chamber 13, the drive assembly drives the stirring rod 14 to rotate. The rotation of the stirring rod 14 fully stirs the various materials in the mixing chamber 13, making them evenly mixed to form a mixed feed suitable for livestock, providing a uniform material base for subsequent conveying and spreading. After the material has been mixed for a period of time, the valve installed is activated, allowing the material to fall into the conveying trough through the feed pipe 7. When the drive assembly is running, it transmits power to the transmission assembly, which drives the spiral blade 31 to rotate in the conveying trough. The rotation of the spiral blades 31 generates axial thrust, propelling the material from the end of the conveying trough near the feed pipe 7 to the end away from the feed pipe 7, thus achieving stable material conveying. When the material is conveyed to the end of the conveying trough by the spiral blades 31, it falls from the discharge port 9 onto the spreading plate 10. When the drive assembly is working, it drives the spreading mechanism to rotate, causing the spreading plate 10 to rotate. Under the centrifugal force of the rotating spreading plate 10, the material falling onto the spreading plate 10 is evenly spread to the marine aquaculture area, ensuring that the cultured organisms can obtain food over a large area, improving feeding efficiency and aquaculture efficiency.

[0026] Please see Figures 1-3As an embodiment of the present invention, the driving assembly includes a driving box 6, which is disposed on the upper side of the feeding box 4. A driving component is disposed in the driving box 6, and a driving shaft 18 is installed at the output end of the driving component. The end of the driving shaft 18 away from the driving component passes through the driving box 6 and the feeding box 4, and the stirring rod 14 and the sealing plate 26 are both installed on the driving shaft 18. The driving assembly also includes a fixed steel frame 1, a reinforcing base 2 is installed at the bottom of the fixed steel frame 1, a reinforcing rod 3 is installed on the feeding box 4, the end of the reinforcing rod 3 away from the feeding box 4 is connected to the fixed steel frame 1, and a connecting rod 5 is installed on the driving box 6. The end of the connecting rod 5 away from the driving box 6 is connected to the fixed steel frame 1.

[0027] In this embodiment, the driving component is installed in the driving housing 6, and its output end drives the driving shaft 18 to rotate. The driving shaft 18 passes through the driving housing 6 and the feeding box 4. The stirring rod 14 is installed on the driving shaft 18, so when the driving shaft 18 rotates, it drives the stirring rod 14 to rotate in the mixing chamber 13, stirring and mixing the material in the mixing chamber 13 to make the material uniform. The fixed steel frame 1 is fixed by the reinforcing base 2. The reinforcing rod 3 on the feeding box 4 is connected to the fixed steel frame 1, and the connecting rod 5 on the driving housing 6 is also connected to the fixed steel frame 1. This structure enhances the stability of the entire device and ensures that it will not be affected by shaking during operation.

[0028] Furthermore, the driving component can be a stepper motor or a servo motor, etc., which will not be described in detail here.

[0029] Please see Figures 1 to 8 As an embodiment of the present invention, the transmission assembly includes a transmission shaft, which is rotatably connected to the side wall of the conveying trough, and one end of the transmission shaft extends into the conveying trough. The spiral blade 31 is mounted on the transmission shaft, and a connecting unit 29 is mounted on the drive shaft 18. The end of the connecting unit 29 away from the drive shaft 18 is connected to the transmission shaft.

[0030] In this embodiment, the drive shaft 18 rotates and transmits power to the transmission shaft via the connecting unit 29. The spiral blades 31 are mounted on the transmission shaft, so the transmission shaft drives the spiral blades 31 to rotate within the conveying trough. Material in the mixing chamber 13 enters the conveying trough through the feed pipe 7. The rotating spiral blades 31 convey the material from the end of the conveying trough closest to the feed pipe 7 to the end furthest from the feed pipe 7, and finally, the material is discharged from the discharge port 9. A valve on the feed pipe 7 controls the material in the mixing chamber 13 to fall into the conveying trough after a period of stirring.

[0031] Furthermore, the connecting unit 29 can be a gear set or a worm gear and worm wheel combination, which will not be described in detail here.

[0032] Please see Figures 1 to 8The material spreading mechanism includes a material spreading rod 16, one end of which is rotatably connected to the bottom wall of the conveyor frame 8, and the other end of which is connected to the material spreading plate 10. A connecting mechanism 15 is installed on the drive shaft 18, and the end of the connecting mechanism 15 away from the drive shaft 18 is connected to the driven shaft 20.

[0033] In this embodiment, when the drive shaft 18 rotates, it transmits power to the spreading rod 16 through the connecting mechanism 15. One end of the spreading rod 16 is rotatably connected to the bottom wall of the conveyor frame 8, so the spreading rod 16 drives the spreading plate 10 to rotate. The material discharged from the discharge port 9 falls onto the spreading plate 10, and the rotating spreading plate 10 spreads the material to the marine aquaculture area through centrifugal force, so that the feed can cover the aquaculture area more widely and improve the feeding effect.

[0034] Furthermore, the connecting mechanism 15 can be a gear set or a pulley set, etc., which will not be described in detail here.

[0035] Please see Figures 1 to 8 The feeding bin 11 is equipped with a stirring blade 24. A driven shaft 20 is rotatably connected to the top wall of the feeding box 4. One end of the driven shaft 20 extends into the feeding bin 11. The stirring blade 24 is installed on the driven shaft 20. A transmission unit 19 is installed on the drive shaft 18. The end of the transmission unit 19 away from the drive shaft 18 is connected to the driven shaft 20. An elastic component 23 is provided on one side of the driven shaft 20. One end of the elastic component 23 is connected to the top wall of the feeding box 4. A bell 22 is installed on the other end of the elastic component 23. A striking rod 21 is provided on one side of the driven shaft 20. One end of the striking rod 21 is fixedly installed on the driven shaft 20.

[0036] In this embodiment, when the drive shaft 18 rotates, it transmits power to the driven shaft 20 through the transmission unit 19. One end of the driven shaft 20 extends into the feeding hopper 11, so the driven shaft 20 drives the stirring blade 24 to rotate within the feeding hopper 11. The rotation of the stirring blade 24 prevents the accumulation and blockage of material in the feeding hopper 11, ensuring that the material can fall smoothly from the discharge port 25 and enter the mixing chamber 13 through the discharge hole 27. During the rotation of the driven shaft 20, it drives the striking rod 21 to rotate. When the striking rod 21 rotates to contact the bell 22, it strikes the bell 22 to produce a sound, which serves as a prompt. The fish associate the sound of the bell 22 with the feeding behavior, forming a conditioned reflex. After the bell is struck, the fish will actively gather in the feeding area, reducing the possibility of feed sinking to the bottom or being washed away by the water flow due to scattered feeding; shortening the feeding time: the rapid gathering of the fish can shorten the feeding cycle and avoid feed dissolution and loss caused by prolonged scattered foraging.

[0037] In this embodiment, the transmission unit 19 can be a gear set or a pulley set, etc., which will not be described in detail here.

[0038] Furthermore, the elastic component 23 can be a spring or an elastic sheet, etc., which will not be described in detail here.

[0039] The working principle of this invention is as follows: When the feeding device of this marine aquaculture farm is working, the drive assembly is activated in the drive box 6, and the output end drives the drive shaft 18 to rotate. The drive shaft 18 passes through the drive box 6 and the feeding box 4, and the stirring rod 14 on it rotates in the mixing chamber 13 to stir and mix various materials. At the same time, the drive shaft 18 transmits power to the transmission shaft through the connecting unit 29, causing the spiral blade 31 to rotate in the conveying trough; when materials need to be fed into the mixing chamber 13, the drive shaft 18 drives the sealing plate 26 to move, so that the discharge hole 27 is aligned with the discharge port 25, and the material falls into the mixing chamber 13. The amount of material can be precisely adjusted by controlling the movement of the sealing plate 26. After the materials have been mixed for a period of time, the valve of the feed pipe 7 is opened, and the materials enter the conveying trough through the feed pipe 7. The spiral blades 31 convey them from one end near the feed pipe 7 to the other end, and finally discharge them from the discharge port 9 onto the spreading plate 10. The drive shaft 18 also transmits power to the spreading rod 16 through the connecting mechanism 15, which drives the spreading plate 10 to rotate, using centrifugal force to evenly spread the materials to the aquaculture area. In addition, the drive shaft 18 drives the driven shaft 20 to rotate through the transmission unit 19. The stirring blades 24 on the driven shaft 20 prevent the material from accumulating and clogging the feeding bin 11. The striking rod 21 rotates to strike the bell 22. When the fish hear the sound, they will actively gather at the feeding area, reducing the possibility of feed sinking to the bottom or being washed away, and shortening the feeding time. The fixed steel frame 1 is fixed by the reinforcing base 2. The feeding box 4 and the drive box 6 are connected to the fixed steel frame 1 by the reinforcing rod 3 and the connecting rod 5, respectively, to enhance the stability of the device.
