Description

Technical Field

[0001] This utility model relates to the field of freshwater fish farming technology, specifically to a device for freshwater fish in reservoirs to prey on rotifers. Background Technology

[0002] Rotifers are an ideal starter food for many fish and shrimp, as they are rich in protein and a variety of essential amino acids, such as lysine and methionine, which are crucial for the rapid growth of fish.

[0003] To promote the rapid growth of freshwater fish, rotifers are regularly introduced into the pond to meet the growth needs of the fry. However, the current feeding method involves catching the rotifers in a net and then scattering them into the pond. This method requires a lot of manual labor, and it is difficult to ensure that the fish can fully consume them. Therefore, further improvements are needed. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides the following technical solution: a reservoir ecological freshwater fish feeding device for rotifers, comprising a feed tank, a buoyancy-providing buoyancy-providing float at the bottom of the feed tank, a motor fixedly installed at the center of the top side of the feed tank, a feed pipe for feeding fixedly installed near the side of the top of the feed tank, six sets of feed inlets arrayed on the bottom wall of the feed tank, a feeding assembly for assisting in the release of rotifers inside the feed tank, six sets of support plates fixedly arrayed on the outer side of the feed tank, side floats for providing buoyancy fixedly installed at the ends of the support plates, a triggering assembly for triggering the feeding assembly in the middle of the support plates, and a photovoltaic panel for providing power to each component on the outer side of the feed tank.

[0005] As an optimization, the triggering component includes a sleeve fixedly installed on the top side of the support plate, a guide rod slidably inserted inside the sleeve, a top plate fixedly installed at the top of the guide rod, a spring fixedly installed between the bottom side of the top plate and the top side of the support plate, a fishing line fixedly installed in the middle of the bottom side of the top plate, a bionic lure fixedly installed at the bottom end of the fishing line, and contacts for contact triggering are respectively provided on the bottom side of the guide rod and the bottom wall of the sleeve.

[0006] As an optimization, the biomimetic bait is curved and simulates the shape of an earthworm.

[0007] As an optimization, the feeding assembly includes a gear disk rotatably connected to the top of the feed tank. A connecting rod is fixedly installed at the center of the top side of the gear disk, and the connecting rod is fixedly installed at the bottom end of the output shaft of the motor via a coupling. An auxiliary feeding component is rotatably connected inside the feed tank at the corresponding feeding port, and the gear disk drives the feeding component.

[0008] As an optimization, the feeding component includes a rotating rod rotatably connected to the top wall of the material tank. A driven gear is fixedly installed at the top of the rotating rod, and the driven gear is meshed with a gear disc. A spiral feeding rod is fixedly installed at the bottom of the rotating rod, and the spiral feeding rod is located inside the feeding port.

[0009] As an optimization, a bearing is provided on the outer side of the top of the rotating rod, and the bearing is installed inside the top of the material tank.

[0010] As an optimization, a solenoid valve is installed inside the discharge port to block the discharge port and prevent rotifers from falling in accidentally.

[0011] The beneficial effects of this utility model are:

[0012] This reservoir's ecological freshwater fish-feeding rotifer device uses biomimetic bait to attract fish to gather. When the fish bite the bait, it moves the guide rod downward, causing the contact points to come into contact with each other. This activates the motor, which in turn rotates the gear disc, causing the rotating rod to rotate and the spiral feed rod to rotate within the feed inlet to assist in the release of rotifers. Because the fish gather together, it is easier for them to prey on the rotifers, thus avoiding waste. Attached Figure Description

[0018] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0019] 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.

[0020] Please see Figure 1-2 A reservoir ecological freshwater fish feeding device for rotifers includes a feed tank 1, a bottom float 2 for providing buoyancy, a motor fixedly installed in the middle of the top side of the feed tank 1, a feed pipe 3 for feeding is fixedly installed near the side of the top of the feed tank 1, six sets of feeding ports 4 are arrayed on the bottom wall of the feed tank 1, an electromagnetic valve is installed inside the feeding port 4 to block the feeding port 4 and prevent rotifers from falling in accidentally, a feeding component for assisting the feeding of rotifers is installed inside the feed tank 1, six sets of support plates 5 are arrayed and fixedly installed on the outside of the feed tank 1, a side float 6 for providing buoyancy is fixedly installed at the end of the support plate 5, a trigger component 7 for triggering the feeding component is set in the middle of the support plate 5, and a photovoltaic panel 8 for providing power to each component is set on the outside of the feed tank 1.

[0021] Please see Figure 3 The triggering component 7 includes a sleeve 9 fixedly installed on the top side of the support plate 5. A guide rod 10 is slidably inserted into the sleeve 9. A top plate 11 is fixedly installed at the top of the guide rod 10. A spring 12 is fixedly installed between the bottom side of the top plate 11 and the top side of the support plate 5. A fishing line 13 is fixedly installed in the middle of the bottom side of the top plate 11. A biomimetic bait 14 is fixedly installed at the bottom end of the fishing line 13. The biomimetic bait 14 is curved and simulates the shape of an earthworm. The bottom side of the guide rod 10 and the bottom wall of the sleeve 9 are respectively provided with contact points 15 for contact triggering. The biomimetic bait 14 can attract fish. When the fish bite the bait, they pull the fishing line 13, causing the top plate 11 to move downward. This will cause the guide rod 10 to slide downward along the inner wall of the sleeve 9. Therefore, the upper contact point 15 will contact the lower contact point 15, which will trigger the feeding component to release rotifers to the fish gathered below.

[0022] Please see Figure 4The feeding assembly includes a gear disk 16 rotatably connected to the top of the feed tank 1. A connecting rod 17 is fixedly installed at the center of the top side of the gear disk 16, and the connecting rod 17 is fixedly installed at the bottom of the output shaft of the motor through a coupling. A feeding device for assisting feeding is rotatably connected inside the feed tank 1 at the feeding port 4, and the gear disk 16 drives the feeding device. When the motor is started, the gear disk 16 will be driven to rotate through the connecting rod 17, which will drive the feeding device to rotate, thereby assisting the rotifers inside to be fed downward from the feeding port 4.

[0023] Please see Figure 4 The feeding component includes a rotating rod 18 rotatably connected to the top wall of the material tank 1. A bearing is provided on the outer side of the top of the rotating rod 18, and the bearing is installed inside the top of the material tank 1. A driven gear 19 is fixedly installed on the top of the rotating rod 18, and the driven gear 19 is meshed with the gear disk 16. A spiral feeding rod 20 is fixedly installed at the bottom of the rotating rod 18, and the spiral feeding rod 20 is located inside the feeding port 4. By engaging with the driven gear 19, the rotating rod 18 can be driven to rotate when the gear disk 16 rotates, thus driving the spiral feeding rod 20 to rotate inside the feeding port 4, thereby facilitating the feeding of rotifers.

[0024] In use, the lower float 2 and the side float 6 provide buoyancy to the device, allowing it to float on the water surface. The biomimetic bait 14, which falls into the water, attracts fish to gather. When the fish bite the bait, the fishing line 13 pulls the top plate 11 downward, which in turn causes the contact points 15 below the guide rod 10 to come into contact with each other. This triggers the start motor and opens the solenoid valve, which in turn drives the gear disk 16 to rotate. The driven gear 19, which meshes with the gear disk 16, drives the rotating rod 18 to rotate when the gear disk 16 rotates. This causes the spiral feed rod 20 to rotate in the feed port 4, which helps to release the rotifers inside downward, making it easier for the fish to prey on the rotifers at a specific point.

[0025] In summary, this reservoir ecological freshwater fish rotifer feeding device attracts fish to gather using the biomimetic bait 14. When the fish bite the bait, it moves the guide rod 10 downward, causing the contact points 15 to come into contact with each other, thus starting the motor. This causes the gear plate 16 to rotate, which in turn rotates the rotating rod 18, which in turn rotates the spiral feeding rod 20 within the feeding port 4 to assist in the release of rotifers. Because the fish gather, it is easier for them to feed, thus avoiding waste.
