Description

Technical Field

[0001] This utility model belongs to the field of aquaculture technology, and in particular relates to a feeding mechanism and a feeding machine. Background Technology

[0002] As the aquaculture and livestock farming industries continue to develop towards large-scale and intensive operations, the farming scenarios are gradually shifting from decentralized manual management to large-scale, high-density, and continuous production models. This places higher demands on the efficiency, accuracy, and stability of feed feeding. Feeding operations have transformed from a single auxiliary link into a key production factor that directly affects farming output, feed utilization, and environmental load.

[0003] In traditional aquaculture, feeding is mainly done manually. While manual feeding offers some flexibility, it suffers from problems such as slow feeding speed, limited feeding volume per feeding, and difficulty in ensuring feeding uniformity. This is especially true in aquaculture, where large-scale, high-frequency feeding is required, making it difficult to meet the efficiency and continuity requirements of modern aquaculture. Furthermore, manual feeding heavily relies on the operator's experience and judgment, leading to feeding deviations. Overfeeding wastes feed and exacerbates water pollution, while underfeeding negatively impacts the growth of aquatic organisms. As aquaculture scales up, labor costs account for an increasingly larger proportion of overall aquaculture costs. The limitations of manual feeding at night and in inclement weather further hinder its adaptation to the actual needs of large-scale aquaculture development.

[0004] To improve feeding efficiency and reduce reliance on manual labor, various automated feeding equipment has gradually emerged in the market. Among them, pneumatic feeders, which use wind power as the conveying force, are widely used in aquaculture and livestock farming due to their advantages such as long conveying distance, wide coverage, and strong adaptability, and are gradually becoming the main feeding equipment in large-scale farms. Existing pneumatic feeders typically include components such as a storage bin, a feeding mechanism, a blower, conveying pipes, a diversion device, and a control unit. The feeding mechanism quantitatively controls the feed, and the airflow generated by the blower transports the feed to the designated feeding area. The feeding mechanism, as the core component connecting the storage and conveying system, directly affects the feeding accuracy, operational stability, and equipment reliability.

[0005] In existing technologies, feeding mechanisms mostly employ a spiral progressive feeding structure, where rotating spiral blades push feed into the conveying channel. While the manufacturing process of this type of structure is relatively mature, gaps inevitably exist between the spiral blades and the shell, resulting in poor overall sealing performance. This is especially problematic when conveying powdery or fine-particle feed, easily leading to material and air leakage. Furthermore, due to insufficient sealing, feed can easily remain in the gaps of the spiral feeding structure. Over time, this residual feed becomes damp, clumps, or even molds. This spoiled feed may be reintroduced into the aquaculture environment during subsequent feeding processes, adversely affecting the health of the farmed animals and the aquatic environment. It also increases the workload of equipment cleaning and maintenance. In addition, during long-term use, oils, moisture, and dust from the feed easily adhere to the spiral blades and the inner wall of the shell. Combined with material accumulation inside the shell, this can easily increase feeding resistance or even cause jamming, affecting the continuous and stable operation of the equipment, accelerating the wear of key transmission components, and shortening the equipment's lifespan.

[0006] On the other hand, aquaculture and some livestock farming scenarios are usually in high humidity environments. The control panels and electrical components of existing feeders are mostly located directly outside the equipment or only have simple protection. Humid air can easily penetrate into the electrical system, causing components to become damp, corroded, or even fail, increasing the equipment failure rate and affecting operational safety.

[0007] Therefore, it is necessary to make targeted improvements to the existing feeding mechanism and related designs to meet the actual needs of the modern aquaculture industry for efficient, stable and reliable feeding equipment. Utility Model Content

[0008] This utility model aims to solve the problems commonly found in existing pneumatic feeders, such as poor feeding sealing, easy accumulation of feed residue, unstable quantitative accuracy, easy damage to control components in humid environments, and insufficient long-term operational reliability. This application proposes a feeding mechanism and feeder with optimized structure. By introducing a reversible rotor with a conical seal, elastic pre-tightening compensation, bidirectional scraping cleaning, stable transmission, and a moisture-proof integrated control structure, it discloses a technical solution that can achieve stable quantitative feeding and reliable airflow delivery in complex aquaculture environments, thereby effectively improving feeding continuity, operational stability, and equipment lifespan.

[0009] In view of this, the first objective of this utility model is to disclose a feeding mechanism, comprising:

[0014] A tilting motor is installed on the feeder cover, and its output end is connected to the transmission assembly to drive the tilting rotor to rotate for periodic feed feeding.

[0015] In some examples of this application, the feeder housing includes a first connecting part, a receiving part, and a conveying part that are arranged and connected sequentially along the feed conveying direction. The first connecting part and the conveying part are respectively arranged on opposite sides of the receiving part. The first feed inlet is arranged on the first connecting part. The receiving cavity is arranged in the receiving part. The conveying channel is arranged inside the conveying part.

[0016] In some examples of this application, the outer wall of the tilting rotor and the inner wall of the receiving cavity are mutually cooperating conical surfaces, and the tilting rotor is arranged in a cross-sectionally tapering shape from the side near the feeder cover to the side away from the feeder cover.

[0017] In some examples of this application, the flipping rotor includes a rotor body with a plurality of raised partition ribs spaced apart on the outer side of the rotor body. A flexible seal is provided on the outer edge of each partition rib, and the flexible seal is interference-fitted with the receiving portion. A first baffle is provided at one end of the rotor body near the feeder cover, and the first baffle is configured to cooperate with the inner wall of the receiving cavity.

[0018] In some examples of this application, the inner wall of the feeder housing is provided with at least two circumferentially spaced edge structures, and the edge structures are configured as scraping edges with an inclined angle along the rotation direction of the flipping rotor.

[0019] In some examples of this application, the feeding mechanism further includes:

[0020] An elastic preload assembly is disposed between the reversing rotor and the drive end of the reversing motor, and is used to apply a continuous axial preload force to the reversing rotor.

[0021] In some examples of this application, the elastic preload assembly includes a spring and a spring receiving portion for accommodating the spring, one end of the spring abutting against the flipping rotor or a component rotating synchronously with the flipping rotor, and the other end abutting against the body or shoulder of the flipping motor via a thrust bearing and / or a clamping post.

[0022] In some examples of this application, the transmission assembly includes a transmission plate fixedly disposed on the tilting rotor. The transmission plate is disposed between the feeder cover and the tilting rotor. The transmission plate has an inner hole or an inner tangent. The output shaft end of the tilting motor has a transmission structure or tangent that cooperates with the inner hole or tangent. The transmission plate is provided with a flower-shaped structure that cooperates with the partition ribs on the tilting rotor. Alternatively, the transmission assembly is a transmission gear column. The transmission gear column is fitted onto the shaft of the tilting motor through a tangent fit. The tilting rotor has internal teeth, and the transmission gear column meshes with the internal teeth of the tilting rotor.

The surrounding frame is located at the upper end of the funnel in a gradually tapering manner from top to bottom, and a display control panel is provided on the surrounding frame.

[0029] Compared with the prior art, the feeding mechanism and feeding machine of this utility model have the following advantages:

[0030] 1. This application improves the core structure of the feeding mechanism, so that the rotating rotor always maintains a stable fit with the receiving cavity during operation. With the continuous axial compensation capability of the elastic pre-tightening component, the fitting gap can be automatically eliminated even under long-term wear or vibration conditions, thereby significantly improving the sealing reliability of the feeding area. The rotor surface is also cleaned synchronously by bi-directional scraping edges to avoid feed adhesion and residue accumulation, making the feeding process cleaner and more controllable, and providing a stable basis for quantitative feeding.

[0031] 2. At the overall application level, this application eliminates the risk of feed clumping and blockage by installing a vibrator at the bottom of the funnel, and strengthens the protection and sealing performance of the feeder shell through the barrel body, top cover and frame structure. The integrated display control board on the frame not only realizes the moisture protection of the control system, but also improves the visibility of the equipment's operating status, making the operation more intuitive and convenient. The functional modules are structurally independent but highly coordinated in function, forming an automated pneumatic feeding solution that is adaptable to harsh breeding environments, has low maintenance requirements and high operational reliability.

[0052] like Figures 1-14 As shown, this application discloses a feeding mechanism, comprising:

[0053] The feeder housing 46 has an internal receiving cavity 467, which is connected to the first feed inlet 466 and the conveying channel 468 respectively.

[0054] The rotating rotor 43 is rotatably disposed within the receiving cavity 467, and a cavity for receiving and conveying materials is formed between its outer wall and the inner wall of the receiving cavity 467.

[0055] A transmission assembly is connected to the flipping rotor 43 for transmitting the power of the flipping motor 42 to the flipping rotor 43.

[0056] The feeder cover 47 is fixedly connected to the feeder housing 46 and is used to close the receiving cavity 467 and to install and position the transmission assembly.

[0057] A flipping motor 42 is installed on the feeder cover 47, and its output end is connected to the transmission assembly to drive the flipping rotor 43 to rotate for periodic feeding of feed.

[0058] The feeding mechanism disclosed in this application, through the rational integration of the overall structure, transforms the feeding process from a traditional pushing or continuous squeezing method to a controllable tilting conveying method. The receiving cavity 467 set inside the feeder housing 46 structurally serves as a load-bearing and guiding function, allowing feed from the storage area to smoothly enter the feeding area under the action of gravity and maintain a stable state. The tilting rotor 43 is set inside the receiving cavity 467 and forms a stable and controllable enclosed space with its inner wall. This space can not only hold a certain amount of feed in a static state, but also stably carry the feed to complete the position transfer during rotation, avoiding the problem of feed being squeezed and deformed or forcibly sheared during the feeding process. In the working state, the tilting motor 42 starts and outputs stable power, which is transmitted to the tilting rotor 43 through the transmission component, causing the tilting rotor 43 to continuously rotate around its own axis inside the receiving cavity 467. When the tilting rotor 43 is in the feeding state... When the feed from the storage area falls naturally through the first feed inlet 466 into the cavity formed between the outer wall of the tilting rotor 43 and the inner wall of the receiving cavity 467, the cavity, along with the feed inside, gradually rotates along a predetermined trajectory from the feeding side to a position close to the conveying channel 468. When the cavity is aligned with the conveying channel 468, the feed inside the cavity falls smoothly into the conveying channel 468 under the combined action of gravity and rotational inertia, completing one feeding process. After completing one feeding, the tilting rotor 43 continues to rotate, causing the emptied cavity to return to the feeding position and receive feed again, thus forming a continuous feeding process. Throughout the entire operation, the feeder cover 47 stably positions the transmission components and the tilting motor 42, ensuring the smooth rotation of the tilting rotor 43 and avoiding jamming or uneven rotation caused by power deviation, so that the feeding action always proceeds according to the predetermined rhythm.

[0059] The feeding mechanism described in this application has an overall structure arranged around the rotating rotor 43 as the core feeding unit. It can achieve relatively stable periodic feeding without relying on complex adjustment mechanisms. Each feeding process is completed by the cavity formed by the rotating rotor 43, thus naturally limiting the amount of feed per feeding at the structural level and reducing the risk of feeding fluctuations caused by structural gaps or uneven compression. The closed receiving cavity 467 structure, together with the overall closed design of the feeder cover 47, helps to reduce the entry of external moisture and impurities into the feeding area, thereby reducing the possibility of feed getting damp and deteriorating. In addition, the power transmission path of this structure is short, reducing unnecessary transmission links and complex linkage structures. This allows the feeding mechanism to maintain complete functionality while having a simple and compact structure. At the same time, it allows the rotating rotor 43 to maintain good rotational stability during long-term operation, reducing the probability of jamming and abnormal wear, and improving the reliability and service life of the feeding mechanism under continuous operation conditions.

[0060] As a preferred example of this application, the feeder housing 46 includes a first connecting portion 463, a receiving portion 464, and a conveying portion 465 that are sequentially arranged and connected along the feed conveying direction. The first connecting portion 463 and the conveying portion 465 are respectively arranged on opposite sides of the receiving portion 464. The first feed inlet 466 is arranged on the first connecting portion 463. The receiving cavity 467 is arranged in the receiving portion 464. The conveying channel 468 is arranged inside the conveying portion 465. This application divides the feeder housing 46 into three main functionally connected parts: a first connecting part 463, a receiving part 464, and a conveying part 465. The first connecting part 463 serves as a material inlet and connects with the upstream storage device. Its structural design ensures that the material can be introduced smoothly and centrally. The receiving part 464 serves as the core working area. The shape and size of its internal cavity are specially adapted to the movement trajectory and sealing requirements of the tilting rotor 43, providing a stable and confined working space for the tilting rotor 43, thereby realizing the quantitative interception and carrying of feed. The conveying part 465 serves as a material outlet. Its internal conveying channel 468 is used to collect and guide the feed released from the tilting rotor 43, ensuring that it can smoothly and directionally enter the subsequent pneumatic conveying pipeline. In some examples of this application, the first connecting part 463, the receiving part 464 and the conveying part 465 are integrally injection molded, which significantly improves the overall strength and stability of the feeding mechanism, effectively reduces the risk of feed leakage and blockage caused by structural loosening or gaps, and at the same time, the integrated structure makes the feed conveying path more continuous and smooth, reduces the possibility of feed stagnation and breakage inside, and helps to maintain feed quality.

[0061] As a preferred example of this application, the outer wall of the tilting rotor 43 and the inner wall of the receiving cavity 467 are mutually mating conical surfaces, and the tilting rotor 43 is arranged with a gradually narrowing cross-section from the side near the feeder cover 47 to the side away from the feeder cover 47. Through the above arrangement, this application enables the tilting rotor 43 to form a more closely fitting and continuous mating relationship within the receiving cavity 467. Compared with traditional cylindrical surfaces or partially fitted structures, this conical surface mating can maintain a large-area contact state throughout the rotation process, thereby effectively reducing the ineffective gap between the two, preventing feed from being retained or leaking in the gap, and further improving the sealing and stability of the feeding area. At the same time, this inclined and gradually narrowing conical surface design structure structurally forms a guiding effect that promotes the concentration of feed in the conveying direction.

[0062] Without adding complex components, this structure achieves a simultaneous improvement in sealing performance, smooth transport, and operational stability through simple and reliable shape matching.

[0063] As a preferred example of this application, the flipping rotor 43 includes a rotor body 432, with a plurality of protruding partition ribs 431 spaced apart on the outer side of the rotor body 432, and a flexible sealing element 434 is provided on the outer edge of each partition rib 431, the flexible sealing element 434 being interference-fitted with the receiving portion 464. This application employs a rotating rotor 43 structure with a partition rib 431 and a flexible seal 434, enabling the rotating rotor 43 to simultaneously possess the dual functions of partitioning and dynamic sealing. The partition rib 431 rationally divides the space between the rotor body 432 and the receiving cavity 467 into multiple relatively independent receiving areas, allowing the feed entering the receiving cavity 464 to be orderly distributed and stably supported, thereby ensuring the uniformity and controllability of each feeding process and preventing the feed from accumulating or flowing randomly during rotation. The flexible seal 434, located on the outer edge of the protrusion of the partition rib 431, fits tightly against the inner wall of the receiving cavity 467 through an interference fit, effectively filling the tiny gaps caused by manufacturing errors or long-term use. While improving sealing performance, the flexible material itself has good elasticity and conformability, allowing it to maintain continuous fit during rotation without causing significant resistance to the normal rotation of the rotor. At the same time, the flexible seal 434 and the partition rib 431 work synergistically, enabling the rotating rotor 43 to dynamically fit and organize the inner wall of the receiving cavity 467 while conveying feed, reducing feed residue. In some examples of this application, the entire flipping rotor 43 is made of a flexible material, such as elastic engineering plastics like TPU. Alternatively, the rotor body 432 and the partition rib 431 of the flipping rotor 43 are made of hard plastic, and the flexible seal 434 is made of a flexible material and is fixed to the partition rib 431 by secondary injection molding, bonding, or other methods.

[0064] By introducing flexible materials, the friction and impact are reduced while ensuring the sealing effect, making the rotating rotor 43 run more smoothly and extending the service life of related components. The overall solution has a simple structure but a high degree of functional integration, which can significantly improve the stability, adaptability and long-term performance of the feeding mechanism in the pneumatic feeding environment of aquaculture or poultry and livestock farming.

[0065] As a preferred example of this application, the tilting rotor 43 further includes a first baffle 433, which is disposed at one end of the rotor body 432 near the feeder cover 47. The first baffle 433 is configured to cooperate with the inner wall of the receiving cavity 467. Through this configuration, the tilting rotor 43 forms a stable and effective blocking structure at its end, thereby specifically addressing the problem of feed leakage and residue easily occurring in the end area of ​​the feeding mechanism. The first baffle 433 is fixedly connected to or integrally formed with the rotor body 432, ensuring it remains in an effective working state throughout the feeding process. Its external dimensions are adapted to the inner wall of the receiving cavity 467, minimizing the end gap to the greatest extent possible without affecting the normal rotation of the tilting rotor 43, forming a continuous end-face blocking effect. Structurally, this restricts the spread of feed between the end of the tilting rotor 43 and the feeder cover 47, preventing feed from entering difficult-to-clean gaps.

[0066] As a preferred example of this application, the inner wall of the feeder housing 46 is provided with at least two circumferentially spaced edge structures, which are configured as scraping edges with an inclined angle along the rotation direction of the flipping rotor 43. In the example of this application, the edge structures are two edges respectively provided on both sides of the outlet of the receiving cavity 467, namely the first edge 461 and the second edge 462. When the flipping rotor 43 rotates, the first edge 461 and the second edge 462 scrape the outer circular surface of the flipping rotor 43 from the inside to the outside and from the outside to the inside, respectively, to remove residual feed from the surface of the flipping rotor 43.

[0067] With the above configuration, the tilting rotor 43 in this application can form a stable and effective cleaning structure at the discharge position during rotation. The inclined edges not only follow the rotation direction of the tilting rotor 43 but also do not generate significant resistance, thereby achieving continuous scraping without affecting the smoothness of rotation, reducing the risk of feed accumulation and clumping, and ensuring the stability and repeatability of the feed output. The two edges adopt opposite scraping directions, so that any feed residue that may be attached to the inner and outer sides of the rotor can be covered and cleaned, avoiding the cleaning dead corners that are easily formed by unidirectional scraping. At the same time, this structure can achieve continuous cleaning without adding additional drive or complex mechanisms, effectively reducing maintenance frequency and improving long-term operational reliability.

[0068] As a preferred example of this application, the feeding mechanism further includes:

[0069] An elastic preload assembly is disposed between the flipping rotor 43 and the drive end of the flipping motor 42, and is used to apply a continuous axial preload force to the flipping rotor 43.

[0070] Through the above settings, this application forms an adaptive clamping system that can actively compensate for gaps. The elastic pre-tightening component uses the elastic element to continuously output a stable axial force to reliably push the flipping rotor 43 against the inner wall of the receiving cavity 467, so that a tight fit can be maintained whether the flipping rotor 43 is stationary or rotating.

[0071] In some examples of this application, the elastic preload assembly includes a spring 412 and a spring receiving portion for accommodating the spring 412. One end of the spring 412 abuts against the tilting rotor 43 or a component that rotates synchronously with the tilting rotor 43, and the other end abuts against the body or shoulder of the tilting motor 42 via a thrust bearing 414 and / or a clamping post 416. Specifically, as Figure 2 As shown, the elastic preload assembly includes a rotor bushing 411, a spring 412, a thrust bearing 414, and a clamping column 416. The rotor bushing 411 is sleeved on the tilting rotor 43. The spring 412 is sleeved inside the rotor bushing 411 and located near the tilting motor 42. One end of the thrust bearing 414 is in contact with the output shaft end face of the tilting motor 42, and the other end is in contact with the clamping column 416. The clamping column 416 abuts against the tilting rotor 43, so that the spring 412 is always in a compressed state and applies an axial preload to the tilting rotor 43. This application provides a rotor bushing 411 with matching dimensions on the rotating rotor 43, and arranges a spring 412 on the inner side of the first mounting cavity 4111 of the rotor bushing 411 near the end of the rotating motor 42. This allows the elastic force of the spring 412 to be stably and evenly transmitted to the rotating rotor 43 through the rotor bushing 411. Thus, without changing the original transmission structure and rotation mode, it provides a continuous and reliable axial preload effect for the rotating rotor 43. Combined with the configuration of the thrust bearing 414 and the clamping column 416, this application ingeniously solves the problem of axial force transmission between the rotating components (the bushing and spring end synchronized with the rotating rotor 43) and the stationary rotating motor 42 body.

[0072] This structure avoids the wear risk caused by the spring 412 acting directly on the surface of the tilting rotor 43. At the same time, with the overall support of the rotor bushing 411, the preload distribution is more uniform, which helps to maintain the force balance on the end face of the tilting rotor 43. In addition, the spring 412 is in a pre-compressed state during assembly and can continue to play a role throughout the entire operation cycle of the equipment without additional adjustment. This ensures the simplicity of the structure and improves the convenience of assembly and maintenance. In conjunction with the tapered fit and flexible sealing structure of the tilting rotor 43, it effectively enhances the overall sealing reliability and operational stability of the feeding mechanism.

[0073] In some examples of this application, the transmission assembly includes a transmission plate 413 fixedly disposed on the flipping rotor 43. The transmission plate 413 is disposed between the feeder cover 47 and the flipping rotor 43. The transmission plate 413 has an inner hole or an inner tangent. The output shaft end of the flipping motor 42 has a transmission structure or tangent that cooperates with the inner hole or the inner tangent. The transmission plate 413 is provided with a flower-shaped structure that cooperates with the partition ribs 431 on the flipping rotor 43.

[0074] Through the above configuration, this application makes the power transmission path in the feeding mechanism more compact and direct. The transmission plate 413 and the output shaft of the flipping motor 42 adopt a fitting method of inner hole or inner tangent surface with the corresponding transmission structure, which can effectively eliminate gaps in the structure and avoid slippage and impact problems that are easy to occur in traditional key connection or friction connection, thereby improving the stability and efficiency of power transmission. At the same time, the flower-shaped structure on the transmission plate 413 and the partition rib plate 431 of the flipping rotor 43 form a reliable meshing, which not only enhances the connection strength between the transmission plate 413 and the flipping rotor 43, but also plays a synchronous positioning role, ensuring coaxiality in the power transmission process and avoiding axial movement, so that the flipping rotor 43 rotates stably in the receiving cavity 467 at the set speed and completes periodic feeding.

[0075] In some examples of this application, such as Figure 4 As shown, the elastic preload assembly includes a spring 412 and a flower-shaped spring pocket 4112. The flower-shaped spring pocket 4112 is fitted onto the flipping rotor 43. The spring 412 is disposed inside the flower-shaped spring pocket 4112 and abuts against the flipping rotor 43, so that the spring is always in a compressed state and applies an axial preload force to the flipping rotor.

[0076] With the above-mentioned elastic pre-tightening structure, the flower-shaped spring pocket 4112 and the flipping rotor 43 are fitted together to form a reliable limit on the spring 412, so that the spring 412 always stays in the preset position during the operation, avoiding deviation or tilting due to rotation, vibration or airflow impact, thereby ensuring that the axial pre-tightening force is stable and consistent. The flower-shaped structure provides multiple points of uniform support for the spring 412, making the force on the spring 412 more balanced during compression and rebound, reducing the adverse effects of local stress concentration on spring performance, delaying the fatigue decay of the spring 412. At the same time, this structure can keep the spring 412 in a naturally compressed state without additional locking or complex adjustment, and can continuously output a stable pre-tightening force for a long time. While ensuring sealing and fitting effect, it simplifies the assembly process and reduces maintenance difficulty.

[0077] In some examples of this application, such as Figure 4 , Figure 6 , Figure 7As shown, the transmission component is a transmission gear 417, which is fitted onto the shaft of the tilting motor 42 via a slit-face fit. The tilting rotor 43 has internal teeth, and the transmission gear 417 meshes with the internal teeth of the tilting rotor 43. This application, through the aforementioned structural design of the transmission gear 417 meshing with the internal teeth and being fitted via a slit-face fit, enables the power output from the tilting motor 42 to be stably transmitted to the tilting rotor 43 without the need for additional complex connecting or locking parts. Assembly is simple and maintenance is convenient. While ensuring effective power transmission, it does not occupy additional axial space and does not interfere with the axial action of the elastic preload component on the tilting rotor, thus achieving a highly reliable and consistent material feeding drive effect under compact structural conditions.

[0078] This application also discloses a feeding machine, comprising:

[0079] The feeder housing 1 includes a funnel 13 for receiving feed;

[0080] Diverter 4 is located below the discharge port of funnel 13, and a feeding mechanism as described in the above embodiment is provided on diverter 4;

[0081] Distributor 5 is connected to the conveying channel 468 of the diverter 4;

[0082] The feeding blower is used to generate airflow to output the feed in the funnel 13 through the diverter 4 and the distributor 5.

[0083] This application integrates the hopper 13, diverter 4, feeding mechanism, distributor 5, and feeding fan into a feeding machine, creating a smooth and continuous feeding path from storage to output. The hopper 13 can stably support a large amount of feed and continuously supply it to the outlet under gravity, reducing feed accumulation and retention during storage. The diverter 4, located below the outlet of the hopper 13, reliably receives feed and is controlled by the feeding mechanism. The fitting structure between the rotating rotor 43 and the receiving cavity 467 in the feeding mechanism, combined with an elastic pre-tightening design, ensures that the feed remains under control as it passes through the feeding mechanism, preventing uneven feeding caused by free fall. Effectively prevents feed leakage when not in operation. The rotating rotor maintains a stable speed under the action of the drive device, so that each rotation and load corresponds to a relatively fixed amount of feed, thus providing a uniform and stable material base for subsequent pneumatic conveying. The conveying channels of distributor 5 and diverter 4 are smoothly connected, so that the pre-quantified feed can be evenly distributed to multiple output directions to meet the needs of multi-point feeding. The airflow generated by the feeding blower runs through the entire conveying path, providing continuous and stable conveying power for the feed, making it less likely for the feed to accumulate or clog in the pipeline. The overall structure is compact, and the coordination between various functional components is clear, which not only ensures the continuity and stability of feeding, but also reduces the maintenance pressure of the equipment during long-term operation.

[0084] In some examples of this application, a vibrator 3 is installed near the bottom of the funnel 13. This arrangement enables the feeder to actively regulate feed flow. The vibrator 3 acts directly on the feed accumulation area, significantly improving the smoothness of feed descent without altering the original guiding structure of the funnel 13. This effectively reduces adhesion and clumping problems caused by changes in feed moisture content or particle shape. Furthermore, the vibrator 3 is compact and installed in a reasonable position, without affecting the funnel's storage capacity or the normal feed descent path, thus improving overall feed continuity while maintaining equipment compactness.

[0085] In some examples of this application, the feeder housing 1 further includes a barrel 14 and an upper flip-top 11. The barrel 14 is fitted over the outside of the funnel 13, and the upper flip-top 11 is located at the upper end of the funnel 13 and / or the barrel 14, for sealing the funnel 13. By setting the barrel 14 outside the funnel 13 and configuring the upper flip-top 11 at the upper end, the feeder housing forms a structural system that combines protection and sealing functions. The barrel 14 provides external support and protection for the funnel 13, reducing the impact of external collisions on the structure of the funnel 13. The upper flip-top 11 effectively seals the feed inlet of the funnel 13 when not feeding, reducing the entry of dust and moisture and ensuring feed quality. The above structural combination comprehensively improves the adaptability and reliability of the feeder in complex aquaculture environments without significantly increasing the complexity of the equipment.

[0086] In some examples of this application, the feeder housing 1 further includes a frame 12, which is arranged in a gradually tapering manner from top to bottom at the upper end of the funnel 13. A display control panel 2 is mounted on the frame 12. This arrangement effectively prevents humid air, moisture, and dust from directly intruding into the display control panel 2, significantly reducing the risk of control panel malfunction or damage due to moisture in humid aquaculture environments, thus improving the long-term reliability and service life of the control system. Furthermore, the reasonable position and wide viewing angle of the upper part of the frame 12 facilitate direct viewing of equipment status information, while reducing the complexity associated with additional supports or independent installation structures. This allows workers to directly view the equipment's operating status, feeding parameters, and fault information without needing to approach or disassemble the protective structure, achieving rapid understanding of the equipment's status and convenient operation, thus achieving a comprehensive optimization effect that balances protection and visibility.

[0087] The feeding mechanism and feeder disclosed in this application have undergone systematic structural optimization around the core objectives of "accurate quantitative measurement, reliable sealing, and stable operation." Through the conical fit between the rotating rotor 43 and the receiving cavity 467, the continuous axial compensation of the elastic pre-tightening component, and the synchronous cleaning design of the bidirectional scraping edges, the feeding process maintains a stable, sealed, and residue-free state during long-term operation, fundamentally reducing problems such as material leakage, jamming, and accumulation. The transmission structure, through the high-matching meshing design of the transmission plate 413 or the transmission gear 417, achieves direct, synchronous, and reliable power transmission, avoiding uneven feeding caused by gaps or slippage in traditional structures. At the overall machine level, the funnel 13 and the diverter 4... The reasonable connection between the distributor 5 and the feeding fan enables a continuous and smooth process from feed storage and quantitative feeding to airflow conveying. At the same time, a vibrator 3 is introduced at the bottom of the funnel 13 to eliminate the risk of feed accumulation. The upper protection and sealing are strengthened by the structure of the frame 12 and the upper flip cover 11. The display control board 2 is integrated on the frame 12, which takes into account the moisture protection of the control system and the visibility of operation. This allows the equipment to operate stably for a long time in the humid and dusty breeding environment. Overall, the simplified structure is exchanged for functional integration, and passive compensation is replaced by frequent adjustment, which greatly improves the feeding accuracy, reliability and adaptability, and meets the actual needs of aquaculture and poultry and livestock farming for high-frequency, automated and low-maintenance feeding equipment.
