Description

Technical Field

[0001] This invention relates to the field of bullfrog farming technology, and in particular to an automatic feeding device for bullfrog farming. Background Technology

[0002] Currently, bullfrog farming primarily relies on manual scattering or simple mechanical feeding methods. Manual feeding is not only time-consuming and labor-intensive, but also difficult to precisely control the amount and scattering range, leading to uneven feeding, bullfrogs competing for food, and low standardization due to the randomness of manual operation. Simple mechanical feeding devices suffer from uneven feed mixing, material sticking to the tank walls causing waste, and have a simple feeding structure with limited feed scattering coverage. Furthermore, the lack of waterproof protection makes them prone to malfunction in the humid environment of the breeding pond, resulting in high maintenance costs. These methods are ill-suited to the efficient and precise feeding requirements of large-scale bullfrog farming, negatively impacting user experience. To address the shortcomings of existing technologies, we propose an automatic feeding device for bullfrog farming. Summary of the Invention

[0003] The main objective of this invention is to provide an automatic feeding device for bullfrog farming, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An automatic feeding device for bullfrog farming includes a mixing tank. A feed hopper is fixedly connected to one side of the mixing tank. Multiple support rods are fixedly connected to the bottom of the mixing tank, and fixed cylinders are fixedly connected to the upper ends of the support rods. A first servo motor is detachably connected to the top of the mixing tank. The output shaft of the first servo motor is detachably connected to a first rotating rod, and a fixed ring is fixedly connected to the outer surface of the first rotating rod. Multiple first fixed rods are fixedly connected to the outer surface of the fixed ring. Two scrapers are fixedly connected to the lower ends of the first fixed rods, and stirring blades are fixedly connected to one side of each scraper. A spiral blade is fixedly connected to the outer surface of the rod inside the fixed cylinder. A discharge cylinder is fixedly connected to the lower end of the mixing tank. A discharge valve is installed in the middle of the discharge cylinder. A dispersing cylinder is fixedly connected to the lower end of the discharge cylinder. Multiple discharge ports are opened on the outer circumferential surface of the dispersing cylinder. A base is fixedly connected to the lower end of the dispersing cylinder. A second servo motor is detachably installed inside the base. A second rotating rod is detachably connected to the output shaft of the second servo motor. A second fixed rod is fixedly connected to the outer surface of the second rotating rod. A conical guide plate is fixedly connected to the top of the second fixed rod. Multiple dispersing plates are fixedly connected to the outer surface of the second fixed rod.

[0005] Preferably, the scraper has an arc-shaped structure, the arc of the scraper matches the arc of the inner wall of the mixing tank, and the scraper is made of food-grade elastic material.

[0006] Preferably, the multiple stirring blades are distributed in a staggered pattern within the mixing tank.

[0007] Preferably, the outer edge of the helical blade is in contact with the inner wall of the fixed cylinder, and the helical blade is continuously arranged along the axial direction of the first rotating rod.

[0008] Preferably, there are several discharge ports, the inner walls of the discharge ports are smooth and polished, and the discharge ports are evenly distributed along the circumference of the dispersing cylinder.

[0009] Preferably, the outer surface of the conical guide plate is polished, and a feeding gap is left between the edge of the conical guide plate and the inner wall of the dispersing cylinder.

[0010] Preferably, the number of dispersing plates is consistent with the number of discharge ports, and the installation height of the dispersing plates is flush with the center height of the discharge ports.

[0011] Preferably, both the first servo motor and the second servo motor are speed-regulating servo motors, and both the first servo motor and the second servo motor are covered with waterproof protective covers.

[0012] Preferably, the bottom of the base has multiple mounting holes for fixing, and the mounting holes are fitted with fixing connectors, and the interior of the base is sealed and waterproofed.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This automatic feeding device for bullfrog farming uses an arc-shaped elastic scraper that rotates against the inner wall of the mixing tank to thoroughly remove feed adhering to the tank wall, preventing raw material waste and scale buildup. At the same time, the staggered stirring blades, combined with the spiral blades inside the fixed cylinder, achieve up-and-down circulation mixing of the feed, making the different feed ingredients more evenly mixed, improving feed palatability, and ensuring balanced nutrition for bullfrogs. It solves the problems of uneven mixing and raw material residue in traditional feeding devices, and the uniformity of single-batch mixing is significantly improved compared to traditional equipment.

[0014] This automatic feeding device for bullfrog farming uses a conical guide plate in conjunction with a number of distribution plates of the same height. The feed is guided by the conical plate to disperse in all directions, and then precisely directed to the discharge port by the rotating distribution plate. Combined with the smooth discharge port that is evenly distributed around the perimeter, the feed can be evenly distributed throughout the breeding pond, avoiding growth differences caused by bullfrogs competing for food. It is suitable for bullfrog breeding ponds of different sizes, greatly improving the spatial coverage and uniformity of feeding, and meeting the feeding needs of bullfrogs in group breeding.

[0015] This automatic feeding device for bullfrog farming uses two speed-regulating servo motors to control the mixing and feeding processes respectively. Farmers can flexibly adjust the motor speed according to the growth stage and stocking density of the bullfrogs. The speed of the spiral blades can control the feed mixing efficiency, and the speed of the dispersing plate can adjust the scattering range and feeding speed, achieving precise control of the feeding amount and range. This avoids waste caused by overfeeding or underfeeding that affects the growth of bullfrogs, and improves the precision of feeding in farming.

[0016] This automatic feeding device for bullfrog farming achieves fully automated operation of feed mixing and feeding, eliminating the need for manual stirring and scattering of feed. This significantly reduces labor costs in bullfrog farming and lowers the workload for farmers. At the same time, the automated process makes feeding time and amount more controllable, avoiding the randomness of manual feeding and improving the standardization of feeding. It is especially suitable for large-scale bullfrog farming bases, effectively improving the overall production efficiency of farming.

[0017] This automatic feeding device for bullfrog farming features a waterproof protective cover for the servo motor, a sealed and waterproof base, and robust structures such as flanges and couplings at key connection points. It is designed to withstand the humid environment of bullfrog ponds, effectively preventing moisture intrusion and equipment malfunctions, thus extending the device's lifespan. Furthermore, most components are detachable, and easily damaged parts such as scrapers and stirring blades are easy to replace and clean, reducing maintenance difficulty and subsequent operating costs.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an automatic feeding device for bullfrog farming includes a mixing tank 1. A feed hopper 2 is fixedly welded to one side of the mixing tank 1. Multiple support rods 3 are fixedly connected in a circular array at the bottom of the mixing tank 1. The upper ends of the multiple support rods 3 are fixedly connected to a fixed cylinder 4. A first servo motor 5 is detachably connected to the top of the mixing tank 1 via a flange. The output shaft of the first servo motor 5 passes through the top wall of the mixing tank 1 and is detachably connected to a first rotating rod 6 via a coupling. A fixed ring 7 is fixedly sleeved on the outer surface of the first rotating rod 6. Multiple first fixed rods 8 are fixedly connected in a circular array on the outer surface of the fixed ring 7. Two arc-shaped scrapers 9 are fixedly connected to the lower end of each first fixed rod 8. A stirring blade 10 is integrally formed on one side of the scraper 9. A spiral blade 11 is fixedly connected to the outer surface of the first rotating rod 6 at a position inside the fixed cylinder 4, which is in contact with the inner wall of the fixed cylinder 4. A discharge cylinder 12 is integrally formed at the lower end of the mixing tank 1. A discharge valve 13 is installed in the middle of the discharge cylinder 12 via a flange. A distribution valve 13 is fixedly connected to the lower end of the discharge cylinder 12. The dispersion cylinder 14 has multiple smoothly polished discharge ports 15 evenly distributed along its outer circumference. A base 16 is fixedly connected to the lower end of the dispersion cylinder 14. A second servo motor 17 is detachably installed inside the base 16 via bolts. The output shaft of the second servo motor 17 is detachably connected to a second rotating rod 18 via a coupling. A second fixed rod 19 is fixedly connected to the outer surface of the second rotating rod 18. A conical guide plate 20 with a polished outer surface is fixedly connected to the top of the second fixed rod 19. A feeding gap is left between the edge of the conical guide plate 20 and the inner wall of the dispersion cylinder 14. Multiple dispersion plates 21 are also fixedly connected to the outer surface of the second fixed rod 19. The number of dispersion plates 21 is consistent with the number of discharge ports 15, and their installation height is flush with the center height of the discharge ports 15. At the same time, both the first servo motor 5 and the second servo motor 17 are speed-regulating servo motors, and waterproof protective covers are fitted on their outer sides. Multiple mounting holes are opened at the bottom of the base 16 and fitted with fixing connectors. The interior of the base 16 is sealed and waterproofed.

[0022] It should be noted that this invention is an automatic feeding device for bullfrog farming. In use, the device is first fixed to the designated feeding position in the bullfrog farming pond via the mounting holes and fixing connectors at the bottom of the base 16. The feed ingredients required for bullfrog farming are then added into the feeding hopper 2. The first servo motor 5 is started, driving the first rotating rod 6 to rotate. The first rotating rod 6 drives the fixing ring 7 and the first fixing rod 8 to rotate, which in turn drives the scraper 9 and the stirring blades 10 to rotate. The arc-shaped scraper 9 rotates against the inner wall of the mixing tank 1, scraping away the feed adhering to the inner wall. The staggered stirring blades 10 initially stir the feed in the mixing tank 1. Simultaneously, the first rotating rod 6 drives the spiral blades 11 in the fixing cylinder 4 to rotate, conveying the feed from the bottom of the mixing tank 1 upwards, creating a circulating flow within the mixing tank 1, allowing different feed ingredients to mix more evenly. After the feed is fully mixed, the discharge valve 13 is opened, and the evenly mixed feed enters the dispersing cylinder 14 through the discharge cylinder 12. The second servo motor is then started. The machine 17 drives the second rotating rod 18 and the second fixed rod 19 to rotate, which in turn drives the conical guide plate 20 and the dispersing plate 21 to rotate. The feed entering the dispersing cylinder 14 is guided by the conical guide plate 20 to disperse in all directions. The rotating dispersing plate 21 further pushes the feed to the discharge port 15 of the dispersing cylinder 14, so that the feed is evenly scattered into the bullfrog breeding pond from multiple circumferentially distributed discharge ports 15. The breeders can adjust the speed of the first servo motor 5 and the second servo motor 17 according to the breeding density and feeding needs of the bullfrogs. The mixing and circulation efficiency of the feed is adjusted by controlling the speed of the spiral blade 11, and the dispersing range and speed of the feed are adjusted by controlling the speed of the dispersing plate 21. After the feeding is completed, the first servo motor 5, the second servo motor 17 and the discharge valve 13 are closed. The entire feeding process is completed automatically without manual feeding. The feed is fully mixed by the upward feeding action of the spiral blade 11, and the uniform dispersing is achieved by the dispersing structure, which greatly improves the feeding efficiency and uniformity of bullfrog breeding.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
