Description

Technical Field

[0001] This utility model belongs to the technical field of aquaculture feeding equipment, and in particular relates to an aquaculture feeder and an aquaculture pond. Background Technology

[0002] Currently, the feeders used in aquaculture ponds are mostly rotary feeders and screw feeders.

[0003] The main working component of a rotary feeder is a central rotary disc, which is usually a rotating disc with multiple evenly distributed toothed plates (or slots). It rotates under the drive of a geared motor to achieve the purpose of feeding. However, this structure has limited adaptability and is often used in places where the feeding accuracy requirement is not high and in places where temporary feeding is required. It cannot effectively adapt to working conditions where long-term or precise feeding is required. The single structure of the rotary disc results in the non-adjustable feeding amount. It can only feed at a single speed and with a fixed feeding amount. The feeding amount is uncontrollable and has the defects of not being able to feed accurately and metered.

[0004] Screw feeders, such as auger conveyors, have a screw shaft as their core component, on which screw blades are installed. The screw blades are arranged at a certain pitch. When the screw shaft rotates, the blades push the material forward. Since the feed is a granular material, it is prone to breakage during the conveying process due to friction between the screw blades and the feed trough, as well as the mutual agitation of the feed itself. This makes it unsuitable for aquaculture sites that require maintaining the integrity of the feed. There may also be problems with feed blockage or spillage, especially when conveying at high speeds or handling highly viscous feed. In severe cases, the machine may jam, resulting in high maintenance costs.

[0005] Therefore, the technical problem to be solved by this utility model is how to design a widely adaptable aquaculture feeder that can accurately weigh feed and reduce feed breakage and jamming. Utility Model Content

In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0052] like Figures 1 to 10As shown, this application provides a livestock feeder, including a feed hopper 100, a first feeding component 200, a second feeding component 300, a weighing device 400, and a control device 500. It can ensure rapid feed dispensing while precisely controlling the feed weight, and can also transmit and display the feed weight, thus helping to improve the accuracy of feed delivery and the livestock farming effect. Specifically:

[0053] The feed bin 100 is used to store bait. The upper part of the feed bin 100 is a round tank and the lower part is a funnel shape. The middle of the funnel shape has a feeding port (not shown in the figure). The bait can be fed into the feeding component from the feeding port. The feeding port is connected to a feeding pipe, which can convey all the bait to the feeding component.

[0054] The first feeding assembly 200 includes a first feeding disc 201 and a first driving mechanism 202. The first feeding disc 201 is located below the feeding port and has a first feeding port. The first driving mechanism 202 is connected to the first feeding disc 201 and is used to drive the first feeding disc 201 to rotate for micro-feeding.

[0055] The second feeding assembly 300 includes a second feeding disc 301 and a second driving mechanism. The second feeding disc 301 is located below the first feeding disc 201. The second feeding disc 301 has a second feeding port, the size of which is smaller than that of the first feeding port. A feeding port (not shown in the figure) is connected below the second feeding disc 301. The second driving mechanism is connected to the second feeding disc 301 and is used to drive the second feeding disc 301 to rotate and feed a large amount of material. The amount of material fed by the second feeding disc 301 in one rotation is greater than that fed by the first feeding disc 201 in one rotation. When the first feeding disc 201 and the second feeding disc 301 rotate, the second feeding port is connected to the first feeding port and the feeding port. The feeding port is connected to the aquaculture pond through a feeding pipe 600.

[0056] Both the first drive mechanism 202 and the second drive mechanism can be driven by a drive motor. During installation, the drive shaft of the drive motor is connected to the first feed plate 201 and the second feed plate 301.

[0057] The weighing device 400 is connected below the second feeding assembly 300. The weighing device 400 is used to weigh the total weight of the feed from the first feeding assembly 200 and the second feeding assembly 300. The weighing device 400 uses a high-precision weighing sensor, which can detect the weight change of the bait in real time and accurately. It can accurately measure different forms of bait, such as powder, granules, and blocks, effectively avoiding measurement errors caused by factors such as changes in bait density and volume.

[0058] The control device 500 is connected to the first drive mechanism 202, the second drive mechanism, and the weighing device 400, respectively. The control device 500 can automatically adjust the feeding speed and feed rate according to preset parameters such as total feeding weight and batching ratio. The feeding speed and feed rate are controlled by adjusting the rotational speed of the first feed disc 201 and the second feed disc 301, eliminating the need for frequent manual intervention and achieving automated control of the feeding process. Simultaneously, the control device 500 can also interface with other automated equipment and control systems, such as PLCs (Programmable Logic Controllers) and DCSs (Distributed Control Systems), further enhancing the automation and intelligence of the production process.

[0059] The control device 500 can also be set to provide continuous feeding, intermittent feeding, or quantitative feeding modes, allowing users to flexibly switch between modes according to actual production needs, thus improving the adaptability and practicality of the livestock feeder. This application does not involve improvements to software or logic control, and therefore will not be elaborated upon.

[0060] The first feeding component 200 and the second feeding component 300 form a double-layer feeding structure. The second feeding component 300 can feed materials quickly and in large quantities, while the first feeding component 200 can feed materials slowly and in small quantities without material spillage. The double-layer structure ensures the stability of the material flow, thereby making the weight signal more accurate and reliable, and further improving the measurement accuracy of the weighing device 400.

[0061] During installation, it also includes an upper mounting base 701 and a lower mounting base 702, which are supported and connected by multiple connecting columns 703. The first drive mechanism 202 is installed above the upper mounting base 701, and the first feeding plate 201 is located below the upper mounting base 701. The drive shaft of the first drive mechanism 202 is connected to the first feeding plate 201. The second feeding plate 301 is located below the first feeding plate 201 and is also located above the lower mounting base 702. The second drive mechanism is installed below the lower mounting base 702, and the drive shaft of the second drive mechanism is connected to the second feeding plate 301. The weighing device 400 is also installed below the lower mounting base 702.

[0062] When it is necessary to use a livestock feeder for livestock feeding, first set the total feeding weight through the control device 500, start the weighing device 400, and then feed according to the large feeding stage and the small feeding stage.

[0063] The large-scale feeding stage includes: starting the second drive mechanism of the second feeding component 300, which drives the second feeding disc 301 to rotate. The bait falls directly from the outlet through the first feeding port into the second feeding port. Then, the second feeding port is fed into the feeding port during rotation. The weighing device 400 weighs the bait during this process. After the bait flows out of the feeding port, the weight detected by the weighing device 400 will decrease. The decreased weight is the feeding weight. During the large-scale feeding stage, the second drive mechanism is turned off after feeding reaches 95% to 99% of the set total weight. This stage is for rapid and large-scale feeding.

[0064] The micro-feeding stage includes: after the second feeding component 300 feeds 95% to 99% of the set total weight, the second drive mechanism of the second feeding component 300 is turned off, and the first drive mechanism 202 of the first feeding component 200 is started. The first drive mechanism 202 drives the first feeding disc 201 to rotate, and the bait enters the first feeding port from the outlet. Since the size of the first feeding port is smaller than that of the second feeding port, and the first feeding port and the second feeding port will overlap during the rotation of the first feeding disc 201, the first feeding port feeds slowly and in small amounts. The bait falls from the first feeding port through the second feeding port into the feeding port and flows out. After the slow feeding reaches 96% to 100% of the set total weight (that is, the feeding amount in the micro-feeding stage is 1% to 5% of the total weight), the first drive mechanism 202 and the feeding port are turned off, and the precise feeding of bait is completed.

[0065] like Figures 7 to 10 As shown, both the first feeding disc 201 and the second feeding disc 301 are disc structures. The first feeding disc 201 is provided with a number of first feeding blades along the axial direction, and a first feeding port is formed between adjacent first feeding blades. The second feeding disc 301 is provided with a number of second feeding blades along the axial direction, and a second feeding port is formed between adjacent second feeding blades. The number of first feeding ports is less than the number of second feeding ports.

[0066] The first and second deflectors are distributed along the axial direction, so that the first and second feeding ports are also distributed along the axial direction, allowing the bait to pass evenly through the first and second feeding ports, thus ensuring uniform feeding and stability of the feed flow. The thickness of the first deflector is greater than that of the second deflector, so the number of first feeding ports is greater than the number of second feeding ports. The first feeding ports can meet the needs of micro-feeding, while the second feeding ports can meet the needs of large-volume feeding.

[0067] like Figure 5 , Figure 6 As shown, the first feeding disc 201 and the second feeding disc 301 are concentrically arranged. The concentric arrangement facilitates the calculation and setting of the speed of the first feeding disc 201 and the second feeding disc 301 to adjust the feeding speed, and also facilitates the weighing device 400 to detect the weight change of the bait.

[0068] like Figure 7 and Figure 9 As shown, the height of the first feeding disc 201 is less than the height of the second feeding disc 301, so the volume of the first feeding disc 201 is less than the volume of the second feeding disc 301. The smaller volume of the first feeding disc 201 can further realize micro-feeding, while the larger volume of the second feeding disc 301 can further realize large-volume feeding.

[0069] like Figure 5 , Figure 6 As shown, the outer diameters of the first feed tray 201 and the second feed tray 301 are equal. This equal outer diameter makes the overall structure of the aquaculture feeder compact and rationally laid out, and also relatively simple and easy to operate during installation, debugging, and maintenance.

[0070] An electric valve is installed at the discharge port, and / or at the feed port. The electric valves are connected to the control device 500 and can be controlled by the control device 500. They are opened for feeding and closed when not in use. This high degree of automation reduces manual intervention, lowers the need for manpower, and saves significant labor costs. It enables fast and accurate feeding and stable operation, improving production efficiency and ensuring smooth production.

[0071] The control device 500 includes a display screen, which can display the output weight of the feed port, the opening and closing status of the electric valve, and the operating status of the first feeding component 200 and the second feeding component 300. The operation is simple and intuitive, making it easy for operators to understand and master.

[0072] The first feeding assembly 200 also includes a first vibration device (not shown in the figure), which is used to vibrate and cause the bait attached to the first feeding disc 201 to fall off;

[0073] And / or, the second feeding assembly 300 further includes a second vibration device (not shown in the figure), which is capable of vibrating to dislodge the feed adhering to the second feeding disc 301. The first and second vibration devices can prevent feed from adhering to the inner wall of the first feeding disc 201 or the second feeding disc 301, thus affecting the feeding process. The vibration device may be a vibration motor.

[0074] The control device 500 is connected to the control terminal equipment, such as a computer or mobile phone, via a remote communication module. Operators can remotely control the aquaculture feeder on a computer or mobile phone and also obtain the real-time working status of the aquaculture pond feeder, which improves convenience.

[0075] This application also provides a breeding pond, comprising:

[0076] The aquaculture feeder described above;

[0077] The pool body is equipped with a feeding port, which is connected to the feeding port of the aquaculture feeder.
