Description

Technical Field

[0001] This invention relates to the field of feeding equipment technology, and more particularly to a feeding device for aquaculture. Background Technology

[0002] Industrialized fish farming typically employs large-scale aquaculture facilities, such as large ponds, to achieve large-scale farming, increase yield and economic benefits. Industrialized fish farming requires the use of aquaculture feeding equipment, which is a mechanical device used to distribute feed at fixed times and in fixed quantities. The main function of this equipment is to accurately deliver feed into the aquaculture water to meet the growth needs of aquatic animals.

[0003] Existing suspended feeding aquaculture devices still have shortcomings. First, they cannot achieve multi-layer feeding, and the feeding area is prone to severe mutual compression. Second, they cannot quickly disperse the feed before feeding, which is not conducive to the fish fry feeding separately.

[0004] The existing patent (publication number: CN117204387A) discloses a suspended aquaculture feeding device that utilizes a buoy and its internal annular float to provide levitation. During feeding, the feed pellets in the buoy are introduced into the outer tube using a feeding screw shaft. The feed pellets in the outer tube are then introduced into the annular feeding area through the feeding channel by the cooperation of the feeding drive component and the feeding driven component. The annular feeding area has multiple layers, and each layer has multiple feeding points. This method allows the feed to be quickly dispersed before feeding, which is beneficial for the fish fry to feed in a dispersed manner. The multi-layer feeding method can avoid the severe mutual compression that can easily occur in the feeding area.

[0005] To address the aforementioned problems, existing patents have provided solutions. However, in actual feeding processes, the feeding range of these devices is limited, making it difficult to feed in large-scale aquaculture areas. Uneven feed distribution can affect the growth rate and yield of aquatic animals, requiring improvement. Therefore, an aquaculture feeding device is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an aquaculture feeding device that has a wide feeding range, makes it easier for fish to obtain feed, promotes the healthy growth of fish, improves breeding efficiency, reduces feed waste, and lowers costs.

Evenly distributed drive blades are fixedly installed on the movable rods. The box is equipped with a drive component. The feed bin is equipped with a stirring rod. The ends of the stirring rods are fixedly installed to the top and bottom ends of the rotating rod, respectively. The design incorporates a box body, top cover, float, horizontal plate, feed bin, motor, feed cylinder, rotating rod, spiral blades, annular opening, feed pipe, collection tray, feeding hole, movable rod, drive blades, and the coordinated operation of the drive components. This allows the aquaculture feeding equipment to have a wide feeding range. In industrialized fish farming, using a feeding equipment with a wide feeding range makes it easier for fish to obtain feed, promotes healthy fish growth, improves farming efficiency, reduces feed waste, and lowers costs.

[0008] Preferably, the driving component includes a drive wheel fixedly mounted on the output shaft of a motor, a driven wheel rotatably mounted on a horizontal plate symmetrical to the motor, a belt sleeved on the drive wheel and the driven wheel, a connecting rod fixedly mounted on the driven wheel, and a second motor housed within the housing. The driving component enables the entire device to move on water. This movement allows for large-scale feeding in the aquaculture pond, and the dispersed feeding also reduces competition for food among fish.

[0009] Preferably, the belt is meshed with and drives the driving pulley and the driven pulley; the bottom end of the connecting rod is fixedly installed with the top end of the bottom movable rod; and the end of the second output shaft of the motor is fixedly installed with the end of the side movable rod.

[0010] Preferably, a weight is fixedly installed at the bottom edge of the housing, and at least four sets of weights are evenly distributed and symmetrically arranged. The second motor is fixedly installed on the weights.

[0027] 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.

[0028] Please see Figure 1-6This invention provides a technical solution: an aquaculture feeding device, comprising a box body 1, a top cover 2 rotatably mounted on the top of the box body 1, floats 3 evenly distributed on the sides of the box body 1 fixedly mounted by support rods, a horizontal plate 4 fixedly mounted inside the box body 1, and feed bins 5 fixedly mounted on both the horizontal plate 4 and the top cover 2, a motor 6 fixedly mounted at the bottom of the box body 1, a feeding cylinder 7 rotatably mounted in the middle of the feed bin 5, a rotating rod 8 disposed inside the feeding cylinder 7, the bottom end of the rotating rod 8 fixedly mounted to the end of the output shaft of the motor 6, the top end of the rotating rod 8 fixedly mounted to the top cover 2, and a spiral blade 9 fixedly mounted on the rotating rod 8. The feed bin 5 is located within the feeding cylinder. Both ends of the 7 are provided with annular openings 10. The top cover 2 is provided with uniformly distributed drop pipes 11. The end of the drop pipe 11 near the feed cylinder 7 is connected to the feed cylinder 7. The end of the drop pipe 11 away from the feed cylinder 7 is provided with a collection plate 12. The side of the collection plate 12 away from the drop pipe 11 is provided with uniformly distributed feeding holes 13. The bottom and both sides of the box body 1 are rotatably provided with symmetrical movable rods 14. The movable rods 14 are fixedly installed with uniformly distributed drive blades 15. The box body 1 is provided with a drive component 16. The feed bins 5 are provided with stirring rods 26. The ends of the stirring rods 26 are fixedly installed with the top and bottom ends of the rotating rods 8, respectively.

[0029] When feeding fish in industrialized fish farming ponds, operators add multi-element fish feed to the feed bins 5 on the horizontal plate 4 and the top cover 2. They then close the valve at the feed inlet of the feed pipe 11, and start the motor 6 inside the housing 1. This causes the output shaft of motor 6 to rotate reciprocally, which in turn drives the rotating rod 8 to rotate reciprocally. The rotating rod 8 then drives the stirring rod 26 to move reciprocally within the feed bin 5. During this reciprocating motion, the stirring rod 26 automatically mixes the multi-element fish feed within the feed bin 5. After mixing, the operator places the housing 1... Inside the aquaculture pond, the buoyancy of the float 3 on the side of the tank 1 causes the tank 1 to float on the water surface. When motor 6 is started, the output shaft of motor 6 rotates, automatically opening the drive unit 16. The drive unit 16 drives the movable rod 14 and drive blade 15 on the bottom of the tank 1 to rotate. When the drive blade 15 rotates in the water flow, it exerts a force on the water and receives a reaction force from the water. This reaction force pushes the drive blade 15, thus moving the tank 1 on the water surface. This opens the switch valve at the feed inlet of the feed pipe 11, and simultaneously, the output shaft of motor 6 rotates, causing the rotating rod 8 to rotate inside the feed cylinder 7. The rotating rod 8 drives the top cover 2 to rotate on the box 1. The rotation of the top cover 2 drives the feed pipe 11 and the collection plate 12 to move in a ring. At the same time, the rotating rod 8 drives the spiral blade 9 to rotate. The bottom surface of the feed bin 5 is set as an inclined surface. Through the annular opening 10 on the feed bin 5 and the rotating stirring rod 26, the feed can always be piled up at the bottom of the spiral blade 9. During the rotation of the spiral blade 9, the feed is transported into the conveying cylinder 7. The conveying cylinder 7 transports the feed into each feed pipe 11. The feed then enters the annularly moving collection plate 12 through the feed pipe 11. Finally, the feed is discharged through the feeding hole 13 on the collection plate 12. The feed is scattered in the water to feed the fish. The entire drive unit moves in the water to feed a wide area of ​​the aquaculture pond. When the motor 6 reverses, it can also drive the spiral blade 9 to reverse. The reverse rotation of the spiral blade 9 can convey the feed downward from the annular opening 10 on the feed bin 5 on the top cover 2. During the feed conveying process, the forward and reverse rotating stirring rod 26 can break up the accumulated and clumped feed, improving the feeding effect. This invention has a wide feeding range. In industrial fish farming, the use of a feeding device with a wide feeding range makes it easier for fish to obtain feed, promotes the healthy growth of fish, improves aquaculture efficiency, reduces feed waste, and lowers costs.

[0030] The driving component 16 includes a drive wheel 161 fixedly mounted on the output shaft of motor 6, a driven wheel 162 rotatably mounted on the horizontal plate 4 symmetrical to motor 6, a belt 163 sleeved on the drive wheel 161 and driven wheel 162, a connecting rod 164 fixedly mounted on the driven wheel 162, and a second motor 165 disposed inside the housing 1. The belt 163 meshes with and drives the drive wheel 161 and driven wheel 162. The bottom end of the connecting rod 164 is fixedly mounted to the top end of the bottom movable rod 14, and the end of the output shaft of the second motor 165 is fixedly mounted to the end of the side movable rod 14. As the output shaft of motor 6 rotates, it drives the drive wheel 161 to rotate. The driving wheel 161 rotates, and the rotation of the driving wheel 162 on both sides rotates simultaneously through the belt 163. The rotation of the driven wheel 162 drives the connecting rod 164 to rotate, and the rotation of the connecting rod 164 drives the movable rod 14 at the bottom of the box 1 and the drive blade 15 to rotate. The motor 165 inside the box 1 is started separately. The output shaft of the motor 165 rotates, which drives the movable rod 14 and the drive blade 15 on both sides of the box 1 to rotate. The rotation of the drive blade 15 at the bottom or sides of the box 1 in the water can drive the entire device to move on the water. The movement of the entire device in the water can enable large-scale feeding in the aquaculture pond. Dispersed feeding can also reduce the competition for food among fish.

[0031] A weight 17 is fixedly installed at the bottom edge of the box 1. The weight 17 is provided in at least four sets that are evenly distributed and symmetrical to each other. The motor 165 is fixedly installed on the weight 17. The evenly distributed weight 17 in the box 1 can enable the whole device to maintain an appropriate depth and posture when floating on water, increase the stability of the whole device when floating on water, reduce the phenomenon of tipping over, and thus improve the stability of the device when moving to feed.

[0032] A cylinder 18 is fixedly installed at the end of the discharge pipe 11 away from the conveying cylinder 7. The cylinder 18 is connected to the opening of the discharge pipe 11. The cylinder 18 has evenly distributed through holes 19 on the side away from the discharge pipe 11. The cylinder 18 is rotatably mounted on the side of the collecting tray 12. The through holes 19 are connected to the inside of the collecting tray 12. An adjusting component 20 is provided on the top cover 2. The adjusting component 20 includes a cylinder 21 fixedly installed on the top of the top cover 2, a crossbar 22 evenly distributed on the end of the output shaft of the cylinder 21, and a hinge rod 23 hinged to the end of the crossbar 22. The end of the hinge rod 23 away from the crossbar 22 is connected to the top of the collecting tray 12. Hinged installation; Activate the cylinder 21 on the top surface of the housing 1. The output shaft of the cylinder 21 rises or falls, driving the crossbar 22 to rise and fall vertically. The vertical rise and fall of the crossbar 22 drives the hinged rod 23 to push or pull the collection tray 12, causing the collection tray 12 to rotate and deflect on the cylinder 18 to adjust the angle. Feed can enter the cylinder 18 through the feed pipe 11, and then enter the collection tray 12 through the through hole 19 on the cylinder 18. Adjusting the angle of the collection tray 12 does not affect the feed entering the collection tray 12. By setting the angle-adjustable collection tray 12, the feeding range can be easily adjusted to ensure that the fish can obtain enough food, while avoiding feed waste and pollution.

[0033] The feeding pipe 11, the collecting tray 12, the crossbar 22, and the hinge rod 23 are arranged in four evenly distributed sets. The floats 3 on the side of the box 1 are also arranged in four evenly distributed sets. The floats 3 are located in the middle of the box 1 and are higher than the drive blades 15 on both sides of the box 1. The evenly distributed four sets of feeding pipe 11, the collecting tray 12, the crossbar 22, and the hinge rod 23 can improve the feeding efficiency. The evenly distributed four sets of floats 3 on the side of the box 1 can improve the stability of the device floating on water. The floats 3 being higher than the drive blades 15 on both sides of the box 1 can ensure that the drive blades 15 are submerged in water after the box 1 is placed in the water.

[0034] The top cover 2 is made of plastic, and the rotating rod 8 is made of high-strength steel. The high-strength steel rotating rod 8 can easily drive the plastic top cover 2 to rotate, reducing the pressure on the motor 6 during operation.

[0035] A feeding pipe 24 is provided on the side of the feed bin 5, and a pipe cap 25 is threadedly connected to the opening of the feeding pipe 24. The pipe cap 25 on the feeding pipe 24 is opened, and fish feed is fed into the feed bin 5 through the feeding pipe 24. After feeding is completed, the opening of the feeding pipe 24 is closed through the pipe cap 25, which makes it easy to feed the feed bin 5 inside the box 1.

[0036] Working principle:

[0037] When feeding fish in industrialized fish farming ponds, operators fill the feed hoppers 5 on the horizontal plate 4 and the top cover 2 with multi-element fish feed. They then close the valve at the feed inlet of the feed pipe 11. After closing, they start the motor 6 inside the tank 1, causing its output shaft to rotate reciprocally. This rotation drives the rotating rod 8 to rotate reciprocally, which in turn drives the stirring rod 26 to move reciprocally within the feed hopper 5. During this reciprocating motion, the stirring rod 26 automatically mixes the multi-element fish feed within the feed hopper 5. After mixing, the operator places the tank 1 on the pond. Inside the breeding pond, the container 1 is placed. The buoyancy of the float 3 on the side of the container 1 causes it to float on the water surface. The motor 6 inside the container 1 is then started. The output shaft of the motor 6 rotates, driving the drive wheel 161 to rotate. This rotation, via belt 163, drives the driven wheels 162 on both sides to rotate simultaneously. The rotation of the driven wheels 162 drives the connecting rod 164 to rotate, which in turn drives the movable rod 14 at the bottom of the container 1 and the drive blade 15 to rotate. When the drive blade 15 rotates in the water flow, it exerts a force on the water and also experiences a reaction force from the water. By forcefully pushing the drive blade 15, the housing 1 moves on the water surface, opening the switch valve at the feed inlet of the discharge pipe 11. Simultaneously, the output shaft of motor 6 rotates, driving the rotating rod 8 to rotate inside the conveying cylinder 7. The rotation of the rotating rod 8 causes the top cover 2 to rotate on the housing 1. The rotation of the top cover 2 causes the discharge pipe 11 and the collecting disc 12 to move in a circular motion. The rotation of the rotating rod 8 also drives the spiral blade 9 to rotate. The bottom surface of the feed bin 5 is set as an incline. Through the annular opening 10 on the feed bin 5 and the rotating stirring rod 26, the feed can always be piled up at the bottom of the spiral blade 9. During the rotation of the spiral blade 9, the feed is conveyed... The feed is fed into the feed cylinder 7, which then delivers the feed to each drop pipe 11. The feed then enters the circular collecting tray 12 through the drop pipe 11. Finally, the feed is discharged through the feeding hole 13 on the collecting tray 12 and scattered in the water to feed the fish. After that, the entire drive unit moves in the water to feed the fish in a large area of ​​the aquaculture pond. When the motor 6 reverses, it can also drive the spiral blade 9 to reverse. The reverse rotation of the spiral blade 9 can deliver the feed downward from the annular opening 10 on the feed bin 5 on the top cover 2. During the feed delivery process, the forward and reverse rotating stirring rod 26 can break up the accumulated and clumped feed, improving the feeding effect.

[0038] When the motor 165 inside the box is started separately, the output shaft of the motor 165 rotates, which drives the movable rods 14 and drive blades 15 on both sides of the box to rotate. The drive blades 15 at the bottom or sides of the box rotate in the water, which can drive the whole device to move on the water. The whole device can move in the water to feed the pond over a large area. Dispersed feeding can also reduce the fish from competing for food.

[0039] Setting a weight 17 inside the housing 1 can maintain an appropriate depth and posture when the device floats on water, increase the stability of the device when floating on water, reduce the occurrence of tipping over, and thus improve the stability of the device when moving to feed.
