Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a multi-point synchronous feeding device for aquaculture ponds. Background Technology

[0002] In the field of aquaculture, scientific and reasonable feeding management is a key link to ensure the healthy growth of farmed organisms, improve the yield and quality of aquaculture, and maximize the benefits of aquaculture. Feeding not only needs to meet the nutritional needs of farmed organisms at different growth stages, but also needs to accurately control the amount, frequency and range of feeding to avoid problems such as feed waste, water pollution and uneven growth of farmed organisms.

[0003] Currently, most of the feeding work in aquaculture ponds is done manually. However, the range of manual feeding is limited, and it is difficult to evenly distribute the feed in the pond, resulting in some fish not being able to eat well.

[0004] The existing patent (publication number: CN221864206U) discloses a feed feeding device for aquaculture ponds, relating to the technical field of feeding devices. This utility model includes a fixed frame, one end of which is fixed with a motor, and the output end of the motor is fixed with a lead screw. The lead screw is rotatably connected to the fixed frame, and a movable block is threadedly connected to the surface of the lead screw. The movable block is slidably connected to the fixed frame, and a channel is opened in the movable block. An air pump blows air into the feeding pipe, causing the feed to roll out of the feeding pipe more quickly, expanding the feeding range. At the same time, when the movable block moves, with the help of gears and toothed plates, it achieves the effect of rotating the feeding pipe, thus achieving the purpose of evenly scattering feed in the aquaculture pond.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1 to 7 This utility model provides a technical solution:

[0032] A multi-point synchronous feeding device for aquaculture pond includes a base 1, a feed pipe 2 is provided above the base 1, a synchronous feeding mechanism 3 is provided at the bottom of the feed pipe 2, and a feed mechanism 4 is provided on one side of the base 1.

[0033] The synchronous feeding mechanism 3 includes multiple feeding pipes 31 located at the bottom of the feeding pipe 2. A control head 32 is located at the bottom of the feeding pipe 31. Multiple mounting plates 33 are rotatably mounted on the top of the base 1. A feeding fan 34 is located on the top of the mounting plate 33. A discharge pipe 35 is located at the bottom of the control head 32. The discharge pipe 35 is connected to the output end of the feeding fan 34.

A control shaft 38 is located in the middle of the multiple control heads 32. Multiple control impellers 39 are located on the control shaft 38. A swing assembly 310 is located between the base 1 and the mounting plate 33. A synchronous drive assembly 311 is located on the top of the base 1.

[0034] Specifically, such as Figure 7 As shown, the swing assembly 310 includes a reciprocating electric push rod 3101 disposed on the top of the base 1. The output end of the reciprocating electric push rod 3101 is fixedly connected to a connecting block 3102. A movable plate 3103 is fixedly connected to the side wall of the connecting block 3102. A plurality of connecting rods 3104 are disposed on the side wall of the movable plate 3103. The two ends of the connecting rods 3104 are respectively hinged to the movable plate 3103 and the mounting plate 33. A support frame 3105 is disposed on the top of the base 1. The movable plate 3103 is movably disposed inside the support frame 3105. The connecting block 3102 is movably connected to the support frame 3105.

[0035] Specifically, such as Figure 4 As shown, the synchronous drive assembly 311 includes a support plate 3111 disposed on the top of the base 1. The feeding shaft 36 and the control shaft 38 both extend to one side of the support plate 3111. One end of the control shaft 38 is provided with a drive wheel 3112, and one end of the feeding shaft 36 is provided with a driven wheel 3113. A transmission belt 3114 is disposed between the drive wheel 3112 and the driven wheel 3113. The size of the driven wheel 3113 is larger than the size of the drive wheel 3112. A drive motor 3115 is bolted to the side wall of the support plate 3111, and the output end of the drive motor 3115 is fixedly connected to the control shaft 38.

[0036] Specifically, such as Figure 6 As shown, an adjusting cover 5 is provided in the middle of the discharge pipe 35, and an adjusting plate 6 is provided inside the adjusting cover 5. Multiple adjusting holes 7 are provided in the middle of the adjusting plate 6. The diameters of the multiple adjusting holes 7 are different. A pull plate 8 is provided on the side wall of the adjusting plate 6. The pull plate 8 is movably connected to the adjusting cover 5. One end of the discharge pipe 35 is rotatably connected to the adjusting cover 5.

[0037] Specifically, such as Figure 5 As shown, the air inlet of the feeding fan 34 is equipped with a filter element 9.

[0038] Specifically, such as Figure 5As shown, the air inlet end of the feeding fan 34 is provided with a protective mesh cover 10, and the bottom of the protective mesh cover 10 is in contact with the filter element 9.

[0039] Specifically, such as Figure 2 As shown, the bottom of the base 1 is provided with multiple adjusting cylinders 11, and the internal threads of the adjusting cylinders 11 are connected to adjusting feet 12.

[0040] In use, the drive motor 3115 is started, and the output end of the drive motor 3115 drives the control shaft 38 to rotate. Under the transmission action of the transmission belt 3114, the driven wheel 3113 is driven to rotate. The driven wheel 3113 drives the conveying shaft 36 to rotate synchronously. The bidirectional spiral blades 37 provided on the side wall of the conveying shaft 36 rotate together with the conveying shaft 36. When the feed enters the conveying pipe 2 from the conveying mechanism 4, the bidirectional spiral blades 37 convey the feed forward along the conveying pipe 2 during rotation, ensuring that the feed can reach the various discharge pipes 31 at the bottom of the conveying pipe 2 evenly and stably. The control shaft 38 is provided with multiple control impellers 39, which rotate synchronously with the control shaft 38. When the feed reaches the discharge pipe 31 and enters the control head 32, the control impellers 39 rotate. The amount of feed entering the feed control head 32 is controlled to ensure that the feed enters the discharge pipe 35 at a uniform speed. The feeding fan 34 starts working. The air inlet of the feeding fan 34 is equipped with a filter element 9 to filter the air entering the feeding fan 34. The bottom of the protective net cover 10 contacts the filter element 9, which protects the filter element 9 and prevents external objects from entering. The feeding fan 34 blows air out from its output end, forming an airflow that transports the feed in the discharge pipe 35 to various feeding areas of the breeding pond. At the same time, the reciprocating electric push rod 3101 in the synchronous drive assembly 311 starts working. The output end of the reciprocating electric push rod 3101 drives the connecting block 3102 to perform reciprocating linear motion. The connecting block 3102 drives the moving plate 3103 inside the support frame 3105. The moving plate 3103 moves synchronously back and forth. Multiple connecting rods 3104 are mounted on the side wall of the moving plate 3103, with their ends hinged to the moving plate 3103 and the mounting plate 33, respectively. When the moving plate 3103 moves back and forth, the connecting rods 3104 drive the mounting plate 33 to swing back and forth around its rotational connection point with the base 1. Since the feeding fan 34 is located on top of the mounting plate 33, and the discharge pipe 35 is connected to the output end of the feeding fan 34, the swinging of the mounting plate 33 drives the discharge pipe 35 to swing synchronously. When the discharge volume needs to be adjusted, the operator pulls the pull plate 8 to move the adjusting plate 6 within the adjusting cover 5, selecting adjusting holes 7 of different diameters to align with the internal channel of the discharge pipe 35. Adjusting holes 7 of different diameters can change the discharge volume of the discharge pipe 35. The base 1 has an efficient feed discharge cross-sectional area, allowing for further fine adjustment of the feed discharge volume to meet the feed requirements of farmed organisms at different stages and densities. Multiple adjusting cylinders 11 are installed at the bottom of the base 1, with adjusting feet 12 threaded inside each cylinder. During installation, the adjusting feet 12 are rotated to move up and down within the adjusting cylinders 11, adjusting the overall height and level of the base 1. This ensures the device can be placed stably and horizontally beside the aquaculture pond, providing a good foundation for its normal operation. Thus, by incorporating multiple feed pipes 31, a feeding fan 34, and a swing assembly 310, simultaneous multi-point feeding in the aquaculture pond is achieved. Multiple feed pipes 31 simultaneously deliver feed, greatly improving feeding efficiency.The oscillating component 310 drives the discharge pipe 35 to oscillate back and forth, ensuring that the feed is evenly distributed throughout the aquaculture pond. This avoids the uneven growth problems caused by uneven feed distribution in traditional feeding methods, promoting balanced growth and improving yield and quality. The uniform feed dispensing is achieved through the cooperation of the feed control shaft 38 and the feed control impeller 39.

[0041] Specifically, such as Figure 5 As shown, the feeding mechanism 4 includes a feeding hopper 41 disposed on one side of the base 1. A feeding pipe 42 is disposed at the bottom of the feeding hopper 41. The feeding pipe 42 is inclined. A connecting pipe 43 communicating with the feeding pipe 2 is disposed at the top of the feeding pipe 42. A feeding shaft 44 is connected to the middle bearing of the feeding pipe 42. A spiral auger 45 is disposed on the side wall of the feeding shaft 44. A servo motor 46 is bolted to the top of the feeding pipe 42. The output end of the servo motor 46 is fixedly connected to the feeding shaft 44.

[0042] In use, the farmer pours the feed to be fed into the feed hopper 41 located on one side of the base 1. The feed hopper 41 serves as a temporary storage for the feed. When feeding is required, the servo motor 46, which is bolted to the top of the feeding pipe 42, is started. Driven by the output shaft of the servo motor 46, the feeding shaft 44 rotates synchronously. The spiral auger 45 on the side wall of the feeding shaft 44 rotates together with the feeding shaft 44. As the spiral auger 45 continues to rotate, the feed moves upward along the inclined direction of the feeding pipe 42 under the push of the spiral auger 45. When the feed is transported to the top of the feeding pipe 42 by the spiral auger 45, under the combined action of the thrust of the spiral auger 45 and the weight of the feed itself, the feed smoothly enters the conveying pipe 2 through the connecting pipe 43, realizing the uniform speed of feed delivery into the conveying pipe 2, so that the feed can be delivered into the conveying pipe 2 in a stable and continuous manner.

[0043] By adopting the above technical solution, the problem that existing feed feeding devices for aquaculture ponds cannot feed feed simultaneously at multiple points and at a uniform speed is solved, resulting in problems such as small feeding range and uneven feeding during the feeding process.

[0044] Working principle: In use, the feed shaft 44 rotates synchronously under the drive of the output shaft of the servo motor 46. The spiral auger 45 installed on the side wall of the feed shaft 44 rotates together with the feed shaft 44. As the spiral auger 45 continues to rotate, the feed moves upward along the inclined direction of the feed pipe 42 under the push of the spiral auger 45. When the feed is conveyed to the top of the feed pipe 42 by the spiral auger 45, under the combined action of the thrust of the spiral auger 45 and the weight of the feed itself, the feed smoothly enters through the connecting pipe 43. The feed conveyor 2 is driven by a motor 3115, which in turn drives a control shaft 38 to rotate. This control shaft, via a transmission belt 3114, drives a driven wheel 3113 to rotate. The driven wheel 3113 then drives the feed conveyor 36 to rotate synchronously. A bidirectional spiral blade 37, mounted on the side wall of the feed conveyor 36, rotates along with the shaft. During rotation, the bidirectional spiral blade 37 conveys the feed forward along the feed conveyor 2, ensuring that the feed reaches each feed pipe 31 at the bottom of the feed conveyor 2 evenly and stably. A control impeller 39 rotates synchronously with the control shaft 38. As the feed reaches the feed pipe 31 and enters the feed control head 32, the rotation of the feed control impeller 39 controls the amount of feed entering the feed control head 32, ensuring that the feed enters the discharge pipe 35 at a uniform speed. The feeding fan 34 blows air from its output end, forming an airflow that transports the feed in the discharge pipe 35 to various feeding areas of the aquaculture pond. At the same time, the output end of the reciprocating electric push rod 3101 drives the connecting block 3102 to perform reciprocating linear motion. The two ends of the connecting rod 3104 are respectively hinged to the moving plate 3103 and the mounting plate 33. In conjunction with the moving plate 3103, when the moving plate 3103 moves back and forth, the connecting rod 3104 drives the mounting plate 33 to swing back and forth around the rotational connection point between it and the base 1. Since the feeding fan 34 is located on the top of the mounting plate 33, the swinging of the mounting plate 33 drives the discharge pipe 35 to swing synchronously, so that the feed can be evenly spread in all areas of the breeding pond. This avoids the problem of uneven feed distribution and growth differences of the cultured organisms caused by the traditional feeding method, which is conducive to the balanced growth of the cultured organisms and improves the yield and quality of the culture.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
