Description

Technical Field

[0001] The present invention belongs to the technical field of aquaculture equipment, and particularly relates to a simple suspended rotating water quality monitoring feeding platform device. Background Art

[0002] With the increasing dietary demand for shrimp, the shrimp farming industry has gradually become industrialized and expanded. The traditional shrimp feeding methods mainly rely on manual throwing or fixed feeding platforms, which have problems such as low efficiency and poor uniformity, easily leading to local feed accumulation or insufficient feeding, and affecting the uniform feeding of the shrimp group. Although the fixed feeding platform can assist in monitoring the feeding situation, its position is restricted by factors such as wind direction, water depth, and season. In addition, most existing feeding devices use fixed-point feeding on the shore or simple mechanical throwing, making it difficult to dynamically adjust the feeding range.

[0003] For existing shrimp feed feeding devices, the feeding range is fixed and cannot be flexibly adjusted according to the breeding density or water area, resulting in local feed surplus or shortage. Moreover, the feed conveying system and the feeding structure of the existing devices are separated, making it difficult to achieve continuous and uniform material distribution. The traditional feeding platform relies on static placement, without considering the water fluidity and the activity rules of the shrimp group. The residual feed after feeding is likely to pollute the bottom sediment, increasing the risk of ammonia nitrogen and nitrite exceeding the standard. Summary of the Invention

[0023] The following various embodiments are only for illustration. Combinations can be made between the various embodiments, and it is not limited to the content shown in the following single embodiment.

[0024] The present invention provides a simple suspended rotary water quality monitoring feeding platform device for feeding fluid shrimp feed, such as Figure 1 shown, which includes a land support platform 1, a rotating elbow 2, and a shrimp feed feeding platform 3; the land support platform 1 includes a rotating seat 11 provided with a through hole penetrating up and down and support feet 12 fixed on the periphery of the rotating seat 11 for support; the rotating elbow 2 has an inverted U-shaped structure, one end of the rotating elbow 2 is rotatably arranged in the rotating seat 11, the shrimp feed feeding platform 3 is installed at the other end of the rotating elbow 2, a water pump 4 is also connected to the rotating end of the rotating elbow 2, a shrimp feed cylinder 5 is arranged below the rotating seat 11, and the end of the rotating end of the rotating elbow 2 extends into the bottom of the shrimp feed cylinder 5; the shrimp feed feeding platform 3 includes a chassis 31 for holding shrimp feed, a support rod 32 is arranged on the peripheral edge of the chassis 31, the support rod 32 is fixedly connected to the outside of the rotating elbow 2, the end of the discharging end of the rotating elbow 2 is fixed in the middle of the chassis 31, and feeding holes 221 for the shrimp feed to flow out are formed around the end of the discharging end of the rotating elbow 2.

[0025] Reference Figure 4 As shown in, this device is arranged on the central island of the shrimp pond. The land support platform 1 is fixed on the central island. The land support platform 1 can be fixed to the ground by setting weights or screwing to the ground. The rotating elbow 2 is rotatably matched with the rotating seat 11 of the land support platform 1. Reference Figure 1, the rotation of the rotating elbow 2 can be controlled and rotated by the driving motor 13, or the lightweight structure can be ensured by manually moving the rotating handle 222; through the rotation of the rotating elbow 2, the shrimp feed dispensing table 3 is moved within the range of the shrimp pond surrounding the central island. The rotating elbow 2 is a connected pipe structure and is connected to the shrimp feed cylinder 5 on the ground. The shrimp feed is centrally placed in the shrimp feed cylinder 5. Through the pumping of the water pump 4, the shrimp feed is transferred from the shrimp feed cylinder 5 along the rotating elbow 2 to the shrimp feed dispensing table 3. The end of the rotating elbow 2 is fixedly connected to the middle of the chassis 31 of the shrimp feed dispensing table 3, and feeding holes 221 are opened around the connection. When the shrimp feed dispensing table 3 is located in the water, the shrimp feed can spread out from the position of the chassis 31 and be spread on the chassis 31.

[0026] The beneficial effects of this device are as follows: This device realizes the mobile feeding of the shrimp feed dispensing table 3 within the range of the shrimp pond roundabout, enabling the shrimp feed to be evenly dispersed into different waters and avoiding local accumulation and water quality pollution; an integrated conveying system with the rotating elbow 2 connected to the shrimp feed cylinder 5 is adopted, combined with the structural setting of the feeding holes 221 on the chassis 31, which not only ensures the continuous and stable feeding of the shrimp feed but also reduces the manual operation intensity; this device adapts to the requirements of different aquaculture scenarios, and at the same time, the centralized storage of the shrimp feed reduces material waste, significantly improving the automation level and feeding efficiency of aquaculture and creating a uniform and controllable feeding environment for the growth of shrimp.

[0027] In a further solution, referring to Figure 2 , the chassis 31 includes an annular edge guard 311 and an elastic material film 312 tightly covering the bottom edge of the edge guard 311. The elastic film is provided with a number of retaining rings 313 diffusing outward from the middle; as shown in Figure 5 and Figure 6 , the discharging end of the rotating elbow 2 includes a main pipe 21 and a sliding pipe 22 hermetically and slidably arranged inside the end of the main pipe 21. A first telescopic cylinder 23 is fixedly arranged on the side of the main pipe 21. A connecting plate 24 is fixedly arranged on the side of the end of the sliding pipe 22. The output end of the first telescopic cylinder 23 is fixedly connected to the connecting plate 24.

[0028] In this structure, through the retraction of the first telescopic cylinder 23, the sliding pipe 22 moves upward along the main pipe 21. The sliding pipe 22 pulls the middle of the elastic material film 312 to bulge upward into a conical structure, and the shrimp feed quickly spreads outward from the middle of the elastic material film 312 and is evenly distributed on the elastic material film 312 under the blocking of a number of stepped retaining rings 313.

[0029] The beneficial effects of this device are as follows: By setting the elastic feed film 312 that can bulge upward, under the traction of the sliding pipe 22, the shrimp feed is concentrated and placed in the middle of the elastic feed film 312, and then blocked by the stepped retaining ring 313, so as to achieve the rapid dispersion and uniform distribution of the shrimp feed, avoid the concentrated accumulation of the shrimp feed, realize the quantitative and large-range distribution of the shrimp feed, improve the feed utilization rate, reduce the waste caused by local accumulation or dissolution of the feed, promote the uniform growth of the shrimp group, avoid individual differences caused by competing for food, improve the specification consistency, and also have effects such as improving water quality.

[0030] In a further solution, as Figure 5 , Figure 6 and Figure 7 , Figure 8 and Figure 9 shown, the upper end of the sliding pipe 22 is fixedly connected with a quantitative column 25 through a plurality of connecting rods. The upper section of the quantitative column 25 is provided with a hollow measuring bin 251. The upper end of the measuring bin 251 is provided with a feeding port 252, and a plurality of discharging ports 253 are opened on the peripheral side of the lower end. The upper section of the discharging end of the rotating elbow pipe 2 is provided with a vertical valve hole 26. The valve hole 26 is in sliding and sealing fit with the quantitative column 25. The valve hole 26 is communicated with the upper horizontal section of the rotating elbow pipe 2. A plug column 27 is also vertically slidably arranged on the upper side of the turning position of the discharging end of the rotating elbow pipe 2. The upper end of the plug column 27 is fixed with a blocking block 271. A spring 272 is directly supported between the blocking block 271 and the rotating elbow pipe 2. The plug column 27 penetrates into the rotating elbow pipe 2 and blocks at the feeding position of the valve hole 26. When the sliding pipe 22 moves upward along the valve hole 26 and pushes open the plug column 27, the feeding port 252 is communicated with the upper horizontal section of the rotating elbow pipe 2, and the discharging port 253 is blocked by the valve hole 26. After the sliding pipe 22 moves downward and leaves the plug column 27, the feeding port 252 is closed, and the discharging port 253 is exposed from the lower end of the valve hole 26. At this time, the elastic soft film still has a conical structure, and the quantitative shrimp feed falls out from the diffusion port and is dispersed.

[0031] In this structure, the quantitative column 25 is set. The quantitative column 25 serves as a quantitative and transfer structure for the shrimp feed. As the first telescopic cylinder 23 retracts and the elastic soft film bulges upward, the quantitative column 25 moves along the valve hole 26, and finally pushes open the plug column 27 that blocks the shrimp feed, connecting the measuring bin 251 with the rotating elbow pipe 2. The shrimp feed in the rotating elbow pipe 2 is pumped into the measuring bin 251 by the water pump 4. After the shrimp feed is filled, as the first telescopic cylinder 23 moves downward, the feeding port 252 of the measuring bin 251 is closed, and the discharging port 253 is exposed from the lower end of the valve hole 26. The shrimp feed in the measuring bin 251 flows out from the discharging port 253 and finally falls on the elastic soft film.

[0032] The beneficial effects of this device are as follows: When the shrimp feed is diffused along with the elastic soft film, this device conducts single-dose quantitative feeding of the shrimp feed, ensuring precise control of the shrimp feed, reducing feed waste, avoiding accumulation or insufficient dispersion of the shrimp feed, ensuring a wide coverage range and uniform distribution of the feed, reducing competition for food among the shrimp group, improving the consistency of specifications, reducing the deposition of residual bait, reducing the accumulation of ammonia nitrogen and nitrite, alleviating water pollution, and the automated quantitative feeding reduces the need for manual intervention. This structure combines mechanical precision with the requirements of aquaculture management, providing technical support for efficient aquaculture.

[0033] In a further solution, as Figure 9 shown, an elastic bottom film 254 is provided at the bottom side of the measuring bin 251, a second telescopic cylinder 255 is provided inside the lower section of the quantitative column 25, a top column 256 is provided at the end of the second telescopic cylinder 255, and the top column 256 is fixed to the lower side of the middle part of the elastic bottom film 254. By moving the top column 256 upward, the capacity of the measuring bin 251 is changed.

[0034] In this structure, by setting the second telescopic cylinder 255, the second telescopic cylinder 255 is remotely controlled to extend and retract a fixed length. As the top column 256 moves up and down, the elastic bottom film 254 changes the volume of the shrimp feed in the measuring bin 251 without blocking the discharge port 253, realizing the change of the single-dose feeding amount of the shrimp feed remotely.

[0035] The beneficial effects of this device are as follows: This device can achieve precise control of the shrimp feed and reduce costs and increase efficiency. It can remotely and quickly adjust the feeding amount according to the growth stage of the shrimp or environmental parameters, optimizing the feeding efficiency.

[0036] In a further solution, as Figure 3 shown, a beam frame 314 for supporting the elastic feed film 312 is further provided at the bottom edge of the side baffle 311.

[0037] The feed rack of the elastic feed film 312 is a cross structure. Through the cross support with the retaining ring 313, it ensures that the elastic soft film is flattened in a horizontal state, providing a good feeding platform.

[0038] In a further solution, as Figure 2 shown, a Secchi disk 6 for observing the water transparency is provided outside the side baffle 311.

[0039] By setting the Secchi disk 6, the water transparency is monitored in real time, the water quality status is accurately judged and management decisions are guided. This indicator directly reflects the fatness of the water body. Aquaculture farmers can dynamically adjust the feed feeding amount, apply probiotics or change the water according to the transparency, thereby preventing water quality deterioration and reducing the disease risk.

[0040] In a further solution, as Figure 2As shown, a fixed platform 28 is provided on the middle section of the discharge end of the rotating elbow pipe 2 towards the outside. A number of guide columns 29 are fixed on the connecting plate 24, and the guide columns 29 extend upward and slide through the fixed platform 28.

[0041] By arranging the guide columns 29, the stability of the vertical movement of the sliding pipe 22 is improved, and problems such as jamming of the sliding pipe 22 caused by the deviation of the sliding pipe 22 are avoided.

[0042] In a further solution, as Figure 10 shown, the shrimp feed cylinder 5 further includes a number of stirring devices. The stirring devices are arranged inside the top end of the shrimp feed cylinder 5. The stirring devices include a stirring motor 51 and a stirring paddle 52 at the end of the stirring motor 51.

[0043] By arranging the stirring devices in the shrimp feed cylinder 5 to stir the fluid shrimp feed, the problem of inconsistent quality of the shrimp feed during feeding caused by the layering of the shrimp feed is avoided.

[0044] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
