Description

Technical Field

[0001] This utility model relates to the field of marine aquaculture technology, specifically to a marine aquaculture feeding and spreading device. Background Technology

[0002] Marine aquaculture, as an important component of the marine economy, has experienced rapid development globally in recent years. Precise and efficient feeding and seeding are crucial for ensuring the healthy growth of farmed organisms and maximizing yields. Proper feeding and seeding ensures that farmed organisms receive sufficient and balanced nutrition, promoting rapid growth and development. Simultaneously, precise control of feed amounts avoids feed waste, reduces aquaculture costs, and minimizes pollution to the aquaculture environment. Therefore, developing a device capable of precise feeding and seeding is of paramount importance for improving the economic and ecological benefits of marine aquaculture.

[0003] Traditional marine aquaculture feeding and seeding techniques have many drawbacks. Traditional feeding methods often rely on manual operation, which is not only labor-intensive and inefficient, but also makes it difficult to achieve precise control of feed quantity and uniform seeding area. Manual feeding is easily affected by factors such as the operator's experience, physical strength, and environment, leading to unstable feeding amounts, sometimes resulting in overfeeding or underfeeding. Overfeeding leads to feed waste, increases aquaculture costs, and uneaten feed decomposes in the water, causing water quality deterioration and affecting the living environment of farmed organisms; underfeeding fails to meet the growth needs of farmed organisms, resulting in slow growth and reduced yields. Furthermore, traditional feeding and seeding techniques cannot be flexibly adjusted according to the different growth stages and feeding habits of farmed organisms, failing to meet the needs of modern, refined, and intelligent marine aquaculture development, severely restricting the sustainable development of the marine aquaculture industry. Therefore, we propose a marine aquaculture feeding and seeding device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a marine aquaculture feeding and spreading device, which solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a marine aquaculture feeder, comprising an adjustment box, a feeding cylinder fixedly connected to the top of the adjustment box, the bottom of the feeding cylinder extending into the interior of the adjustment box, a fixing plate fixedly connected to the bottom of the feeding cylinder, a feeding port opened at the top of the fixing plate, a limiting groove opened at the bottom of the fixing plate near the feeding port, a rotating disk movably connected to the bottom of the inner wall of the adjustment box, two obliquely spaced oblique limiting grooves distributed in an annular pattern opened at the top of the rotating disk, a baffle slidably connected to the top of the inner wall of the limiting groove, and one bottom end of the baffle inserted into one side of the inner wall of the oblique limiting groove.

[0006] Preferably, the output end of the feed inlet extends to the bottom of the regulating box, and the output end of the baffle has a semi-circular cross-section.

[0007] Preferably, a gear ring is fitted onto the outer wall of the rotating disk, a forward and reverse motor is fixedly connected to one side of the outer wall of the fixed plate, and a gear is fixedly connected to the bottom rotating shaft of the forward and reverse motor, wherein the gear and the gear ring are meshed.

[0008] Preferably, the bottom of the regulating box is fixedly connected to four fixed columns that are equally spaced in a rectangle, and a floating raft is provided at the bottom of the fixed columns.

[0009] Preferably, the bottom of the fixing column is fixedly connected to one end of the top of the floating raft.

[0010] Preferably, a discharge pipe is welded to the bottom output end of the regulating box, and the end of the discharge pipe away from the regulating box passes through the top end of the floating raft.

[0011] Preferably, the bottom of the floating raft is fixedly connected to two electric propellers that are equidistantly distributed laterally.

[0012] Compared with the prior art, this utility model provides a marine aquaculture feeding and spreading device, which has the following beneficial effects:

[0013] 1. Compared to traditional marine aquaculture feeding and broadcasting techniques, this device offers significant advantages in adjusting feed output. Traditional feeding methods typically rely on manual experience to estimate feed amounts, making precise control difficult and often resulting in overfeeding or underfeeding. Overfeeding leads to large amounts of uneaten feed sinking to the bottom, wasting feed, increasing aquaculture costs, and causing these residues to decompose in the water, consuming large amounts of oxygen and producing harmful substances such as ammonia nitrogen, thus deteriorating water quality, affecting the living environment of farmed organisms, and even causing disease. This device, through the ingenious combination of a rotating disc, an inclined limiting groove, and a baffle, can precisely control the opening and closing of the feed inlet, thereby achieving precise adjustment of the feed output. Farmers can flexibly adjust the feed output according to the different growth stages, feeding habits and actual farming conditions of the farmed organisms to ensure that the farmed organisms receive sufficient and balanced nutrition. This not only avoids feed waste and reduces farming costs, but also effectively reduces water pollution caused by feed residues, creating a good living environment for the farmed organisms and helping to improve farming yield and quality.

[0014] 2. This marine aquaculture feeding broadcaster has significant shortcomings in terms of broadcasting position adjustment compared to traditional marine aquaculture feeding broadcasting techniques. Traditional techniques typically use fixed-position broadcasting, resulting in a limited broadcasting range and difficulty in ensuring even feed coverage across the entire aquaculture area. This leads to uneven feeding among aquaculture organisms, with some areas experiencing slow growth due to insufficient feed, while others may have excessive feed, negatively impacting overall aquaculture efficiency. This device features two horizontally equidistant electric propellers at the bottom of the floating raft. By controlling the start, stop, and speed of these propellers, the position of the broadcaster on the water surface can be flexibly adjusted. Aquaculture personnel can move the broadcaster to a suitable position based on the actual layout of the aquaculture area, water flow conditions, and the distribution of aquaculture organisms, thereby expanding the broadcasting range and ensuring wider feed coverage. This guarantees even feed intake for aquaculture organisms, improving the uniformity of aquaculture and overall efficiency. This flexible broadcasting position adjustment function allows the device to better adapt to different aquaculture environments and needs, providing a strong guarantee for efficient and precise feeding in marine aquaculture.

[0015] 3. This aquaculture feeder employs a clever design involving a rotating disc, an inclined limiting groove, and a baffle to precisely adjust the feed output. The inclined limiting groove on the rotating disc works in conjunction with the baffle that slides within it. When the rotating disc is driven by a forward and reverse motor, the baffle reciprocates within the limiting groove, changing its position at the feed inlet and precisely controlling the opening and closing of the inlet. This precise adjustment method allows for flexible adjustment of feed output based on the different growth stages, feeding habits, and actual aquaculture conditions of the farmed organisms. This avoids the problems of feed waste or insufficiency found in traditional feeding methods, reducing aquaculture costs while ensuring that the farmed organisms receive sufficient and balanced nutrition, thus improving their growth rate and yield.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] Please see Figure 1-4 A marine aquaculture feeder includes an adjusting box 1. A feeding cylinder 2 is fixedly connected to the top of the adjusting box 1. The bottom of the feeding cylinder 2 extends into the adjusting box 1. A fixing plate 3 is fixedly connected to the bottom of the feeding cylinder 2. A feeding port 4 is opened at the top of the fixing plate 3. A limiting groove 5 is opened at the bottom of the fixing plate 3 near the feeding port 4. A rotating disk 6 is movably connected to the bottom of the inner wall of the adjusting box 1. Two oblique limiting grooves 7 are opened at the top of the rotating disk 6 in an annular arrangement. A baffle 8 is slidably connected to the top of the inner wall of the limiting groove 5. One end of the baffle 8 is inserted into one side of the inner wall of the oblique limiting groove 7, so that the baffle 8 can slide in the limiting groove 5. By cooperating with the oblique limiting groove 7, the position of the baffle 8 at the feeding port 4 can be changed, thereby controlling the opening and closing degree of the feeding port 4 and thus adjusting the feed output.

[0023] Furthermore, the output end of the feed inlet 4 extends to the bottom of the regulating box 1, and the output end of the baffle 8 has a semi-circular cross section. The extension of the output end of the feed inlet 4 to the bottom of the regulating box 1 facilitates the direct fall of feed into the bottom of the regulating box 1, which is convenient for subsequent spreading. The semi-circular cross section of the output end of the baffle 8 allows it to slide more smoothly in the limiting groove 5, reducing jamming and improving the accuracy and stability of the adjustment.

[0024] Furthermore, a gear ring 9 is fitted onto the outer wall of the rotating disk 6, and a forward and reverse motor 10 is fixedly connected to one side of the outer wall of the fixed plate 3. A gear 11 is fixedly connected to the bottom rotating shaft of the forward and reverse motor 10. The gear 11 and the gear ring 9 are meshed. The forward and reverse motor 10 can drive the rotating disk 6 to rotate through the meshing connection between the gear 11 and the gear ring 9. By rotating the forward and reverse motor 10, the rotation direction of the rotating disk 6 can be precisely controlled, thereby realizing the reciprocating motion of the baffle 8 in the limiting groove 5, and achieving the purpose of adjusting the feed output.

[0025] Furthermore, the bottom of the regulating box 1 is fixedly connected to four fixed columns 12 that are equidistantly distributed in a rectangle. The bottom of the fixed columns 12 is provided with a floating raft 13. The four fixed columns 12 fixedly connected to the bottom of the regulating box 1 provide stable support for the entire device.

[0026] Furthermore, the bottom of the fixed column 12 is fixedly connected to one end of the top of the floating raft 13. This connection method allows the floating raft 13 to stably support the regulating box 1 along with the fixed column 12. At the same time, the floating raft 13 can float up and down according to the actual situation, which not only ensures the stability of the device, but also improves the flexibility of sowing, and can better adapt to different aquaculture environments and water surface conditions.

[0027] Furthermore, a discharge pipe 14 is welded to the bottom output end of the regulating box 1. The end of the discharge pipe 14 away from the regulating box 1 passes through the top end of the floating raft 13. The setting of the discharge pipe 14 allows the feed output from the feed inlet 4 to pass smoothly through the bottom of the regulating box 1 and be discharged. The design of passing through the top end of the floating raft 13 allows the output end of the discharge pipe 14 to adjust its height as the floating raft 13 floats, ensuring that the feed can be accurately spread to the breeding area, thus improving the spreading effect and quality.

[0028] Furthermore, two horizontally equidistant electric propellers 15 are fixedly connected to the bottom of the floating raft 13 near the discharge pipe 14. These two horizontally equidistant electric propellers 15 provide the power for the entire spreader to move. By controlling the start, stop, and speed of the electric propellers 15, the position of the spreader on the water surface can be flexibly adjusted, thereby expanding the spreading range and enabling the feed to cover the aquaculture area more extensively, improving aquaculture efficiency and uniformity. At the same time, the electric propellers also enhance the adaptability and operability of the spreader in complex aquatic environments.

[0045] Working principle: First, feed enters from the feeding cylinder 2, which extends to the bottom of the regulating box 1, and is output through the feeding port 4 at the top of the fixed plate 3. A limiting groove 5 is formed at the bottom of the fixed plate 3 near the feeding port 4. A baffle 8 is slidably connected within the limiting groove 5. One end of the baffle 8 is inserted into the inner wall of the inclined limiting groove 7 at the top of the rotating disk 6. When feed spreading needs to be controlled, the forward and reverse motor 10 is started. A gear 11 is fixedly connected to the rotating shaft at the bottom of the forward and reverse motor 10. The gear 11 meshes with a gear ring 9 fitted onto the outer wall of the rotating disk 6. The rotation of the forward and reverse motor 10 drives the gear 11 to rotate. Through meshing with the gear ring 9, the gear 11 drives the rotating disk 6 to rotate at the bottom of the inner wall of the regulating box 1. Since one end of the baffle 8 is inserted into the inclined limiting groove 7, the rotation of the rotating disk 6 causes the inclined limiting groove 7 to move, thus causing the baffle 8 to slide back and forth within the limiting groove 5. When the baffle 8 slides towards the feed inlet 4, it gradually blocks the feed inlet 4, reducing the feed output. When the baffle 8 slides away from the feed inlet 4, the feed inlet 4 gradually opens, increasing the feed output. This linkage allows for precise control of the feed output from the feed inlet 4. Four rectangular, equidistantly distributed fixed posts 12 are fixedly connected to the bottom of the regulating box 1. The bottom of each fixed post 12 is fixedly connected to the top of the floating raft 13, ensuring the floating raft 13 floats stably on the water surface. A discharge pipe 14 is welded to the bottom output end of the regulating box 1. The end of the discharge pipe 14, away from the regulating box 1, passes through the top of the floating raft 13. After the feed is output from the feed inlet 4, it passes through the bottom of the regulating box 1 and is discharged and spread through the discharge pipe 14. The floating raft 13 floats up and down with the water surface fluctuations, ensuring that the output end of the discharge pipe 14 remains at a suitable water level, allowing the feed to be evenly spread throughout the aquaculture area.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
