Description

Technical Field

[0001] This utility model relates to the field of automatic feed dispensing technology, and in particular to an automatic feed dispensing device for crab farming. Background Technology

[0002] In the modern crab farming industry, automated feed dispensing equipment is a crucial facility for improving farming efficiency and reducing labor costs. Precise and efficient feed dispensing not only ensures the healthy growth of crabs but also effectively avoids feed waste and optimizes the utilization efficiency of farming resources, which is essential for the development of large-scale, intelligent crab farming.

[0003] Currently, traditional crab farming feed distribution and loading equipment relies heavily on manual operation, resulting in significant efficiency bottlenecks and resource waste. Manual feed distribution requires loading and unloading each feeding bin individually, making simultaneous loading and unloading impossible and leading to substantial waiting time, severely hindering farming efficiency. During loading, it's difficult to precisely control the amount of feed, easily resulting in over- or under-loading, causing feed waste and potentially impacting crab growth due to insufficient feeding. Furthermore, the fixed volume of the feeding bins in traditional equipment cannot flexibly adapt to the changing needs of crabs at different growth stages or in varying farming scales. When the farming scale expands or feed requirements change, frequent equipment replacements or complex manual adjustments are necessary, leading to high operating costs and a high risk of distribution errors. Simultaneously, existing equipment lacks a precise sealing control mechanism, making it difficult to guarantee the accuracy and stability of feed delivery, further affecting crab farming results and economic benefits. Therefore, there is an urgent need to develop a new type of automated feed distribution equipment for crab farming that can achieve efficient alternating operations and precise control of loading and feed delivery. In response to this technical problem, this application proposes an automatic feed dispensing device for crab farming. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic feed dispensing device for crab farming. This device utilizes a semi-circular gear, a first gear, a rotating rod, and a feeding hopper to achieve alternating operation of two feeding hoppers, with unloading and loading occurring simultaneously, significantly reducing waiting time and greatly improving efficiency compared to traditional manual dispensing. Simultaneously, rollers and a sliding disc precisely control the opening and closing of the sealing cap, ensuring accurate and stable feed dispensing. The device employs a linkage mechanism between a second motor, a second gear, and a rack and pinion to achieve intelligent adjustment of the feeding hopper volume, offering significant advantages over traditional manual dispensing. For different farming stages or scale changes, the motor can drive the turntable and feeding hopper to move up and down, increasing the volume by moving downwards during loading and decreasing it by moving upwards to reduce volume, precisely controlling the amount of feed dispensed. This meets batch dispensing needs while avoiding feed waste. Furthermore, the circular guide design ensures smooth and precise volume adjustment, effectively preventing mechanical failures and dispensing errors caused by hopper misalignment, significantly improving the efficiency of aquaculture resource utilization, and reducing manual dispensing costs and error risks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic feed dispensing device for crab farming, comprising an operating table, a support platform fixedly connected to the bottom left side of the operating table, a motor 1 at the bottom of the support platform, a semi-circular gear fixedly connected to the drive end of the motor 1, a gear 1 meshing with the outer wall of the semi-circular gear, a rotating rod inside the gear 1, a turntable 2 fixedly connected to the top of the rotating rod, a turntable 1 on the outer wall of the rotating rod, a small feed hopper inside the turntable 2, a large feed hopper inside the turntable 1, a sliding disc at the bottom of the turntable 1, a sealing cover connected to the large feed hopper via a swing assembly, and a support frame fixedly connected to the middle left side of the operating table, the support frame being connected to a fixing block via a telescopic assembly.

[0006] Furthermore, the swing assembly includes an L-shaped bracket fixedly connected to the outer wall of the large filling barrel, a rotating shaft is provided at the bottom of the L-shaped bracket, the outer wall of the rotating shaft is provided on the outer wall of the sealing cover, and a roller is fixedly connected to the top of the sealing cover.

[0007] Furthermore, the telescopic assembly includes a second motor disposed on the top of the support frame, a second gear fixedly connected to the drive end of the second motor, a rack meshing with the outer wall of the second gear, a moving rod fixedly connected to the right outer wall of the rack, a support disc fixedly connected to the top of the moving rod, and the top of the support disc fixedly connected to the bottom of the fixed block.

[0008] Furthermore, a ring is fixedly connected to the outer wall of the fixed block, and the ring is slidably connected to the outer wall of the rotating rod.

[0009] Furthermore, the small loading hopper is located inside the large loading hopper, and a discharge hopper is provided on the top left side of the operating platform.

[0010] Furthermore, the top of the roller is positioned at the bottom of the sliding disc for opening and closing the sealing cover.

[0011] Furthermore, a sliding disc is fixedly connected to the top of the fixed block, and the top of the first turntable is located at the bottom of the second turntable.

[0012] Furthermore, a collection device is provided on the top right side of the control panel.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, the device uses a semi-circular gear, a gear, a rotating rod, and a feeding hopper to achieve alternating operation of two feeding hoppers, completing the loading process while unloading, significantly reducing waiting time and greatly improving efficiency compared to traditional manual distribution; the opening and closing of the sealing cover is precisely controlled by the cooperation of rollers and sliding discs to ensure the accuracy and stability of the bait dispensing amount.

[0015] In this invention, the equipment achieves intelligent adjustment of the feeding hopper volume through the linkage mechanism of motor two, gear two, and rack and pinion, offering significant advantages over traditional manual feeding. Facing different breeding stages or scale changes, the equipment can precisely control the feeding amount as needed. When more feeding is required, the motor drives the turntable and feeding hopper to move downwards to expand the capacity, quickly meeting batch assembly needs; when the feeding amount decreases, the reverse drive reduces the volume, eliminating feed waste. Simultaneously, the circular guide design ensures a smooth and precise volume adjustment process, effectively avoiding mechanical failures and distribution errors caused by feeding hopper misalignment. This improves the efficiency of aquaculture resource utilization and reduces the operational costs and error risks of manual feeding. Attached Figure Description

[0022] 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.

[0023] Reference Figures 1-3 An embodiment of this utility model provides an automatic feed dispensing device for crab farming, comprising an operating table 1, a support platform 2 fixedly connected to the bottom left side of the operating table 1, a motor 3 at the bottom of the support platform 2, a semi-circular gear 4 fixedly connected to the drive end of the motor 3, a gear 5 meshing with the outer wall of the semi-circular gear 4, a rotating rod 6 inside the gear 5, a turntable 8 fixedly connected to the top of the rotating rod 6, a turntable 7 on the outer wall of the rotating rod 6, a small feed hopper 10 inside the turntable 8, a large feed hopper 11 inside the turntable 7, a sliding disc 12 at the bottom of the turntable 7, an L-shaped bracket 14 fixedly connected to the outer wall of the large feed hopper 11, a rotating shaft 15 at the bottom of the L-shaped bracket 14, the outer wall of the rotating shaft 15 being disposed on the outer wall of a sealing cover 16, and a roller 13 fixedly connected to the top of the sealing cover 16.

[0024] Specifically, when using this equipment, motor 3 is started, driving the semi-circular gear 4 to rotate. This drives gear 5, which meshes with the semi-circular gear 4, to rotate. Gear 5's rotation drives rotating rod 6, which in turn drives turntables 7 and 8 connected to its outer wall to rotate. The rotation of turntables 7 and 8 drives the large and small material containers 11 and 10, which are symmetrically distributed inside, to rotate. The rotation of the large material container 11 causes roller 13 to slide on sliding disc 12. Because sliding disc 12 has a concave surface on its right side, when roller 13 moves to the concave track on the right side of sliding disc 12, it generates a vertical displacement. This displacement is transmitted to the sealing cover 16 through rotating shaft 15, thereby enabling the sealing cover 16 to passively open and close. After the bait is assembled in the large feeding hopper 11 and the small feeding hopper 10 connected below the feeding hopper 24, the feeding hopper filled with bait will be moved to the collection device by the rotation and opening mechanism formed by the turntable, gear and sealing cover 16. After the sealing cover 16 is opened, the bait will be put in. At this time, the other set of feeding hoppers will rotate to the feeding hopper 24 for bait assembly, thereby realizing automatic alternating distribution. Compared with traditional manual distribution, the alternating loading of the two sets of feeding hoppers can improve work efficiency.

[0025] Reference Figures 2-4 A support frame 9 is fixedly connected to the middle of the left side of the operating table 1. A motor 2 17 is installed on the top of the support frame 9. A gear 2 18 is fixedly connected to the drive end of the motor 2 17. A rack 20 is meshed with the outer wall of the gear 2 18. A moving rod 19 is fixedly connected to the outer wall of the right side of the rack 20. A support disc 21 is fixedly connected to the top of the moving rod 19. The top of the support disc 21 is fixedly connected to the bottom of the fixed block 22. A ring 23 is fixedly connected to the outer wall of the fixed block 22. The ring 23 is slidably connected to the outer wall of the rotating rod 6.

[0026] Specifically, when the amount of bait to be loaded increases, motor 17 is started, gear 18 rotates clockwise, driving rack 20, which meshes with gear 18, to move downwards. Rack 20 drives moving rod 19 and support disc 21 downwards, thereby driving turntable 7, which is connected to sliding disc 12 via fixed block 22, to move downwards. At this time, large loading hopper 11 also moves downwards, thus expanding the volume of the hopper. Small loading hopper 10 is fixed inside turntable 8 and does not move up or down. The large loading hopper is located outside of it. The loading amount is controlled by the up-and-down movement of the large loading hopper 11, ensuring that it does not rise above the small loading hopper 10, thus preventing the small loading hopper 10 from retracting into the large loading hopper 11 and affecting the feeding. When the required loading amount is small, the drive motor 17 reverses, causing the gear 18 to move upwards, along with the rack 20. The moving rod 19, support disc 21, fixed block 22, sliding disc 12, and turntable 7 also move upwards, thereby reducing the volume of the loading hopper. Compared to traditional manual loading, this device offers more precise control and avoids waste. The ring 23 acts as a guide, preventing the turntable 7 from deflecting during its up-and-down movement.

[0027] Reference Figure 1 , Figure 3 and Figure 4 The small feeding hopper 10 is located inside the large feeding hopper 11 to adjust the amount of bait to be loaded. The top of the roller 13 is located at the bottom of the sliding disc 12 to open and close the sealing cover 16. The top of the fixed block 22 is fixedly connected to the sliding disc 12. The top of the turntable 1 7 is located at the bottom of the turntable 2 8. The top of the left side of the operating table 1 is provided with a feeding hopper 24, and the top of the right side of the operating table 1 is provided with a collecting device.

[0028] Specifically, the small feeding hopper 10 and the large feeding hopper 11 are combined, and the amount of bait to be held is adjusted by a telescopic component. The fixed block 22 serves as a support and connection to prevent the turntable 7 from tilting when the moving rod 19 is lifted. The bait moves from the feed hopper 24 into the small feeding hopper 10 through the action of the semi-circular gear 4, gear 5 and turntable 8, and is then transported to the collection device.

[0029] Working principle: When using this device, after starting motor 3, its drive end drives the semi-circular gear 4 to rotate. Due to the special structure of the semi-circular gear 4, it only meshes with gear 5 at a specific angle, thereby driving gear 5 to rotate periodically. The rotation of gear 5 drives the rotating rod 6 to rotate, thus causing turntable 7 and turntable 8 to rotate synchronously. Large feeding bins 11 and small feeding bins 10 are symmetrically distributed on turntable 7 and turntable 8. As the turntables rotate, the feeding bins move sequentially to the bottom of the feeding hopper 24 to receive the bait. Among them, the outer wall of the large feeding bin 11 is connected to the roller 13 via the L-shaped bracket 14 and is in close contact with the bottom of the sliding disc 12. When the large feeding bin 11 rotates with the turntable to the concave area on the right side of the sliding disc 12, the roller 13 is affected by the concave contour and undergoes a vertical displacement change. The displacement is transmitted to the sealing cover 16 via the rotating shaft 15, causing the sealing cover 16 to rotate around the rotating shaft 15, thus opening the cover. When the roller 13 leaves the concave area, the sealing cover 16 automatically closes under the action of gravity or a reset mechanism, thereby precisely controlling the timing of bait release. The two feeding hoppers operate alternately. When the hopper filled with bait rotates to the top of the collecting device, the sealing cover 16 opens to unload the bait, and the empty hopper rotates synchronously to the bottom of the feeding hopper 24 to receive the bait, forming a continuous automatic distribution process. When it is necessary to adjust the feeding volume, the second motor 17 is started to drive the second gear 18 to rotate, which converts the rotational motion into linear motion through meshing with the rack 20. When gear 18 rotates clockwise, rack 20 moves downward, causing moving rod 19, support disc 21, and fixed block 22 to move downward simultaneously. This, in turn, causes sliding disc 12 and turntable 7 connected to fixed block 22 to move downward, and the large feeding hopper 11 descends accordingly, increasing the internal space to accommodate more bait. Conversely, when gear 18 rotates counterclockwise, all components move upward, reducing the volume of the feeding hopper. Ring 23 is fitted onto the outer wall of rotating rod 6, providing stable guidance for the up-and-down movement of turntable 7, preventing it from shifting during lifting and ensuring feeding accuracy. Small feeding hopper 10 is located inside large feeding hopper 11, and large and small feeding hoppers 11 are arranged side by side. Through the cooperation of telescopic components and turntable structure, flexible adjustment of different feeding amounts can be achieved. The feed falls from the hopper 24 on the top left side of the operating table 1, and is precisely delivered into the small feed hopper 10 through the transmission of the semi-circular gear 4, gear 5 and turntable 8. The feed is then transported to the collection device by the turntable. The whole process does not require manual intervention, which effectively improves the efficiency and accuracy of feed distribution in crab farming.
