Description

Technical Field

[0001] This utility model relates to the field of sturgeon farming technology, and in particular to a feeding device for sturgeon farming. Background Technology

[0002] Sturgeon, an ancient cartilaginous fish with hard scales, occupies an important position in freshwater aquaculture. Its flesh is tender and nutritious, and its caviar has extremely high economic value, making it one of the important species in aquaculture. From the perspective of the aquaculture environment, sturgeon has high requirements for water conditions and is suitable for growing in clear water with sufficient dissolved oxygen. Common aquaculture methods include pond culture, cage culture, and recirculating aquaculture systems. At the same time, sturgeon farming has strict requirements for feed utilization and water quality stability. Therefore, the rationality of the feeding device is directly related to the farming efficiency and economic benefits, and it must be fully adapted to its ecological habits and the needs of the farming scenario.

[0003] Existing feeding devices typically use fixed-point feeding, while sturgeon may be distributed in different areas of the pond. During operation, there is often an excess of feed near the feeding area, which can easily rot and pollute the water due to uneaten food. Conversely, areas farther from the feeding point may receive insufficient feed, leading to inadequate feeding for some sturgeon, affecting the uniformity of group growth and wasting feed. Furthermore, feed can easily accumulate at the discharge port, causing blockages and residues, which can lead to mold growth and bacterial contamination over time. Additionally, the devices are often designed as a single unit, making disassembly and cleaning inconvenient. Therefore, this application proposes a feeding device for sturgeon farming. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing feeding devices, such as easy blockage of the feed outlet due to feed accumulation, uneven feed distribution, and cumbersome maintenance and cleaning. Therefore, this invention proposes a feeding device for sturgeon farming.

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

[0006] A feeding device for sturgeon farming includes a box body, a top cover mounted on the top of the box body via two symmetrically arranged hinges, a handle fixedly connected to the upper surface of the top cover, a flow guide slope provided inside the box body, an extension box mounted on the side wall of the box body, and a movable plate provided on the side of the extension box away from the box body.

[0007] The box is equipped with a discharge mechanism, which includes an assembly base. Multiple levers are mounted on the assembly base, and the multiple levers are connected by an elastic rope.

[0008] As a further preferred embodiment of this technical solution, the bottom of the box and the extension box are respectively provided with multiple fixing rods, and the bottom of the multiple fixing rods are connected to a base.

[0009] As a further preferred embodiment of this technical solution, the extension box is provided with a discharge chute, and the discharge chute is connected to the interior of the box body;

[0010] The extension box has a sealing groove on the side away from the box body, and the movable plate is set in the sealing groove.

[0011] As a further preferred embodiment of this technical solution, a support rod is fixedly connected to the bottom of the movable plate. The support rod is embedded in the bottom of the extension box. One end of the support rod is rotatably connected to the side wall of the sealing groove, and the other end of the support rod is connected through the extension box.

[0012] A rubber pad is provided at the end of the movable plate away from the support rod, and the length of the rubber pad is equal to the length of the sealing groove;

[0013] The first motor is detachably mounted on the outer wall of the extension box via multiple sets of bolts, and the output shaft of the first motor is connected to one end of the support rod extending outside the extension box via a coupling.

[0014] As a further preferred embodiment of this technical solution, the mounting base is disposed at the bottom of the box, and the mounting base is rotatably connected to the inner wall of the bottom of the box;

[0015] Multiple dial plates are arranged circumferentially, and each dial plate has a through hole aligned with the others. The elastic rope is disposed in the through hole corresponding to the position.

[0016] As a further preferred embodiment of this technical solution, a second motor is detachably installed at the bottom of the housing via multiple sets of bolts. The output shaft of the second motor is connected through the bottom side wall of the housing and extends into the housing. The output shaft of the second motor is connected to the bottom key of the mounting base.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model, through the provision of a second motor and mounting base, enables multiple baffles located at the bottom of the box to rotate synchronously after the second motor is started. This pushes the feed particles inside the box to the discharge chute, and the kinetic energy provided by the baffles propels the feed particles outward, ultimately scattering them into the sturgeon breeding pond for feeding. The elasticity of the baffles, in conjunction with the elastic rope, can adaptively adjust the feeding distance according to the height of the feed accumulation, ensuring that the feed is distributed to different areas of the breeding pond. This avoids the sturgeon from stressing and fighting over food due to concentrated feeding, thus preventing them from injuring each other. At the same time, the cutting effect of the elastic rope on the bottom feed reduces the density of the feed accumulation, preventing the feeding efficiency from being reduced due to blockage at the bottom of the box.

[0019] 2. This utility model, through the setting of a first motor and a support rod, can adjust the angle between the movable plate and the extension box by starting the first motor, thereby guiding the feed at the feed trough to fly out at different angles, further improving the uniformity of feeding in the sturgeon breeding pond. Moreover, when feeding in areas far from the breeding pond, the feed particles fly obliquely upward along the initial angle of the movable plate and then fall downward, increasing the kinetic energy when colliding with the water surface of the breeding pond, which can better identify the feeding area and facilitate the sturgeon in the breeding pond to feed.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] This utility model provides a technical solution: such as Figure 1 and Figure 2As shown, a feeding device for sturgeon farming includes a box 1. Multiple fixing rods are respectively aligned at the bottom of the box 1 and the extension box 2, and the bottoms of the multiple fixing rods are connected to a base 11. The height of the base 11 is higher than the height of the second motor 44 below the box 1, providing some protection for the second motor 44. A top cover 12 is installed on the top of the box 1 via two symmetrically arranged hinges 121. A handle 122 is fixedly connected to the upper surface of the top cover 12. The top cover 12 can be opened via the handle 122 to facilitate adding feed into the box 1. The side walls of body 1 and the center of top cover 12 are replaced with transparent material to facilitate observation of the feeding status inside body 1. A guide slope 13 is provided inside body 1. The bottom of guide slope 13 is circular and its diameter is the same as the diameter of the circular area formed by multiple deflectors 42. During the feeding of sturgeon, the accumulated bait inside body 1 can slide to the bottom of body 1 and be sent out of body 1 by deflectors 42, reducing the amount of bait residue inside body 1 after feeding, facilitating precise control of the amount of bait added, and facilitating subsequent cleaning of the inside of body 1.

[0029] like Figure 3 and Figure 4 As shown, an extension box 2 is installed on the side wall of the box 1. A movable plate 3 is provided on the side of the extension box 2 away from the box 1. A discharge trough 21 is opened on the extension box 2 and is connected to the inside of the box 1. A sealing groove 22 is opened on the side of the extension box 2 away from the box 1, and the movable plate 3 is placed in the sealing groove 22. A support rod 31 is fixedly connected to the bottom of the movable plate 3. The support rod 31 is embedded in the bottom of the extension box 2. One end of the support rod 31 is rotatably connected to the side wall of the sealing groove 22, and the other end of the support rod 31 is connected through the extension box 2. A rubber pad 33 is provided on the side of the movable plate 3 away from the support rod 31, and the length of the rubber pad 33 is equal to the length of the sealing groove 22. When the movable plate 3 is rotated to fit the sealing groove 22, the rubber pad 33 can tightly fill the gap between them, preventing the feed from leaking out of the gap and causing waste when not feeding. At the same time, it prevents water vapor and impurities in the breeding pond from entering the interior of the extension box 2 in reverse, reducing the risk of feed getting damp or contaminated, and indirectly reducing the probability of the discharge channel being blocked.

[0030] In addition, the first motor 32 is detachably installed on the outer wall of the extension box 2 by multiple sets of bolts, and the output shaft of the first motor 32 is connected to one end of the support rod 31 extending outside the extension box 2 via a coupling. It should be noted that after the first motor 32 is started through the support rod 31, the output shaft of the first motor 32 can drive the movable plate 3 to rotate around the support rod 31 as the axis, thereby adjusting the angle between the movable plate 3 and the extension box 2. When the bait is propelled outward by the force provided by the push plate 42, it gains initial upward kinetic energy along the inclined surface of the movable plate 3 under the guidance of the movable plate 3, which can adjust the feeding angle, so that the bait is scattered a longer distance in the breeding pond. If the movable plate 3 rotates downward (forming a small angle with the extension box 2), the bait will fly out with a gentler trajectory, covering the near shore area, achieving coverage of different areas of the breeding pond, avoiding the stress of sturgeon to compete for food due to concentrated feeding, and the dispersed distribution of bait also allows sturgeon in different areas to have sufficient feeding opportunities, improving the uniformity of sturgeon growth in the breeding pond.

[0031] like Figure 5 and Figure 6 As shown, the interior of the housing 1 is equipped with a discharge mechanism 4, which includes an assembly base 41. Multiple levers 42 are mounted on the assembly base 41, and multiple levers 42 are connected by a common elastic rope 43. The assembly base 41 is located at the bottom of the housing 1 and is rotatably connected to the inner wall of the bottom of the housing 1. The multiple levers 42 are arranged circumferentially, and each lever 42 has a through hole aligned with its position. The elastic rope 43 is placed in the corresponding through hole. A second motor 44 is detachably installed at the bottom of the housing 1 by multiple sets of bolts. The output shaft of the second motor 44 is connected through the bottom side wall of the housing 1 and extends into the housing 1. The output shaft of the second motor 44 is connected to the bottom of the assembly base 41 by a key.

[0032] Specifically, after the second motor 44 is started, its output shaft will drive the mounting base 41 to rotate, thereby causing the multiple circumferentially arranged levers 42 to rotate synchronously. This circumferential distribution allows the levers 42 to evenly distribute the bait at the bottom of the box 1, preventing the bait from accumulating in dead corners due to uneven local force. The levers 42 can be made of a slightly deformable material, allowing them to adaptively adjust their shape when contacting bait of varying density. Combined with the multiple sets of elastic ropes 43 between the levers 42, they can effectively manage the accumulation of bait. Achieving a certain cutting effect separates the sticky or compacted bait clumps into loose small particles, thus separating the bait that has gathered together. This reduces the probability of large pieces of bait clogging the discharge chute 21 and makes the bait easier to disperse during the pushing process, providing a basis for subsequent uniform throwing. It also reduces the damage to the deflector plate 42 and the second motor 44 caused by bait blockage during the feeding process. Furthermore, as the deflector plate 42 and the elastic rope 43 accumulate their own elastic potential energy, they can release a large thrust to move the bait at the bottom, eliminating the need for manual intervention to clear blockages in a timely manner.

[0033] Furthermore, as the feeding progresses and the amount of bait in the box 1 decreases, the pressure exerted by the bait above on the bait at the bottom of the box 1 decreases. Under the same power, the reaction force on the deflector 42 of the second motor 44 decreases, and its conversion efficiency between rotation speed and pushing force is higher. This allows the bait to obtain a greater projectile force when it flies out of the discharge trough 21, which can increase the throwing distance of the bait and improve the uniformity of feeding. The device can cover the near area when there is enough bait and extend to the far area when there is less bait, thus achieving dynamic and uniform coverage of the pond space. This avoids waste caused by the concentrated falling of bait being stirred up by the fish and sinking to the bottom. It is also more in line with the sturgeon's dispersed feeding habits and reduces the risk of local competition for food.

[0034] Furthermore, after feeding is completed, the top cover 12 is opened and clean water is injected into the box 1. When the second motor 44 drives the deflector 42 to rotate, it can drive the water flow to flush the inner wall of the box 1 and the guide slope 13. The deflector 42 itself has a micro-deformation ability to scrape off residual bait debris, mucus and other dirt and discharge them with the water flow, avoiding the pollution caused by residual dirt mold to the next feeding, and greatly reducing maintenance costs.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
