Description

Technical Field

[0001] This utility model belongs to the field of cage aquaculture technology, specifically a precise feeding device for fish in cage aquaculture. Background Technology

[0002] Cage aquaculture is a method of high-density fish farming by setting up cages in natural waters such as lakes and oceans. The core is to use the natural aquatic environment to achieve efficient fish farming. The farming efficiency is high: the cage space is concentrated, and fish fry can be stocked at high density. The yield per unit area is much higher than that of traditional pond farming. The fish are concentrated in the cage, making feeding, observing growth status and harvesting operations simpler and saving manpower.

[0003] An investigation revealed that a utility model patent (publication number: CN219719468U) discloses an automatic feed dispensing device for freshwater fish farming. The device includes a feed pipe and a hopper. The hopper is positioned above one side of the feed pipe and is connected to the inside of the feed pipe via a conduit. Multiple vertical pipes are evenly connected to the bottom of the feed pipe, and these vertical pipes are connected to the inside of the feed pipe. A baffle plate slidably extends horizontally through the bottom of the feed pipe. A feed inlet is provided on the surface of the baffle plate on the side of the vertical pipe. An electric actuator is fixed to the bottom of the feed pipe below the hopper via a bracket, and the electric actuator is connected and fixed to the end of the baffle plate. This utility model's technical solution involves setting the hopper at an angle above the fishpond. The feed in the hopper flows into the feed pipe and into the vertical pipe under gravity. By using the electric actuator to move the baffle plate and release the blockage at the bottom of the vertical pipe, the feed can be distributed in strips over a relatively large area of ​​the fishpond.

[0004] Although the aforementioned patent, through the design of components such as feed pipes, hoppers, and electric push rods, and the cooperation of these components, enables the electric push rods to drive the baffles to remove the obstruction at the bottom of the vertical pipe during the feeding process, thus allowing the fish feed to fall quickly and making it easier for the fish to eat, the rapidly falling feed can cause it to scatter due to impacting the water surface during feeding. This is not only detrimental to the fish's ability to concentrate on eating, but it can also stick to the inner wall of the net cage, causing pollution of the net cage and wasting fish feed.

[0005] Therefore, it is necessary to design a device that can provide centralized and precise feeding, avoiding feed waste and pollution of the net cages. Utility Model Content

[0006] To address the above technical problems, this utility model provides a device that can provide centralized and precise feeding, avoiding feed waste and pollution of the net cages, thereby solving the problem of existing net cage fish farming feeding devices that cause fish food waste and pollution of the net cages due to large-scale feeding.

[0007] To solve the above technical problems, the technical solution of this utility model is: a precision feeding device for fish in net cage aquaculture, including a mounting frame and a feeding component, wherein the feeding component includes a slider that is slidably connected to the inner wall of the mounting frame;

[0008] The feeding assembly also includes a limiting seat, a material cylinder, and an electric push rod. The material cylinder is installed on the inner wall of the limiting seat, and the electric push rod is installed on the top of the material cylinder. A blocking plate is fixedly connected to the output end of the electric push rod. Several hollow tubes are fixedly connected to the bottom of the blocking plate. A feeding ring is fixedly sleeved on the outer wall of the hollow tube. A drive assembly is provided on one side of the mounting frame.

[0009] Furthermore, the bottom end of the slider slides against the inner wall of the mounting bracket via a pulley, and the tops of the two sliders are fixedly connected to a fixing plate via a crossbar. The top of the fixing plate is fixedly connected to the bottom of the limiting seat via a truss.

[0010] Furthermore, the drive assembly includes a float plate fixedly connected to one side of the mounting frame, a slide table fixedly connected to the top of the float plate, a base slidably connected to the inner wall of the slide table, and a winch mounted on the top of the base.

[0011] Furthermore, traction hooks are fixedly connected to both sides of the slider, threaded seats are fixedly connected to both ends of the mounting bracket, and the output end of the winch is connected to the traction hook on the same side via a rope.

[0012] Furthermore, a feed pipe is fixedly connected to the upper top end of the feed cylinder, and a cone is fixedly connected to the upper top end of the feed pipe.

[0013] Furthermore, the bottom of the mounting frame is detachably connected to the cage body, and the outer surface of the cage body is provided with mesh holes.

[0014] Furthermore, a push handle is fixedly connected to the outer surface of the base, and a grip is fixedly connected to the ends of the two push handles.

[0015] This utility model has the following advantages compared with the prior art:

[0016] 1. This utility model, by setting up a feeding component, enables the feeding cylinder to be moved precisely by a slider during the feeding process of farmed fish through the cooperation of various parts, thereby reducing the labor intensity of manual feeding. By setting up a feeding cylinder and a blocking plate, and fixing a feeding ring to the outer wall of the blocking plate, the fish food can be contained inside the feeding ring, preventing the fish food from flowing with the water flow, causing fish food waste and pollution of the net cage body, resulting in net cage blockage and reduced service life.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figures 1 to 4 The device shown is a precision feeding device for cage-cultured fish, including a mounting frame 1 and a feeding component. The feeding component includes a slider 2 that is slidably connected to the inner wall of the mounting frame 1.

[0025] The feeding assembly also includes a limiting seat 3, a feed cylinder 4, and an electric push rod 5. The feed cylinder 4 is installed in the middle of the limiting seat 3 and is designed to have sufficient capacity to hold at least the amount of feed consumed by all the fish in the net cage body 17 at one time. To control the outflow of feed from the feed cylinder 4, the electric push rod 5 is installed at the top of the feed cylinder 4. The output end of the electric push rod 5 is fixedly connected to a blocking plate 6. The size of the blocking plate 6 is just enough to completely seal the opening on the ground of the feed cylinder 4, and the height of the blocking plate 6 is above the water surface. Several hollow tubes 7 are fixedly connected. The hollow tubes 7 can reduce the weight of the telescopic end of the electric push rod 5. A feeding ring 8 is fixedly sleeved on the outer wall of the hollow tube 7. The diameter of the feeding ring 8 is designed according to the amount of fish in the net cage body 17, and can enclose the feed inside the feeding ring 8. The height of the feeding ring 8 is also designed according to the size of the water surface fluctuation, ensuring that there is a part of the feeding ring 8 above and below the water surface, so as to avoid the fish food being washed away by the water flow and wasting the fish food. A drive component is set on one side of the mounting frame 1.

[0026] In order to ensure that the feeding component can slide on the mounting frame 1, the bottom end of the slider 2 slides against the inner wall of the mounting frame 1 through the pulley 9. The top of the two sliders 2 is fixedly connected to the fixing plate 10 through the crossbar. The crossbar can ensure that the sliders 2 on both sides can move simultaneously under the traction of the drive component. The top of the fixing plate 10 is fixedly connected to the bottom of the limit seat 3 through the truss. The fixing plate 10 is set in the middle of the crossbar.

[0027] In order to provide power to the feeding component and enable it to move left and right for precise feeding, the drive component includes a float 11 fixedly connected to one side of the mounting frame 1. A slide 12 is fixedly connected to the top of the float 11, and a base 13 is slidably connected to the inner wall of the slide 12. A winch 14 is installed on the top of the base 13. In this embodiment, floats 11 are provided on both sides of the mounting frame 1, and the same slide 12 is provided on the float 11. The base 13 is slidably connected inside the slide 12, and a winch 14 is fixedly connected to the base 13. The winches 14 on both sides are connected to traction hooks 15 on different sides, which can ensure that the feeding component returns to its original position after feeding.

[0028] In order to enable the feeding assembly to move via the winch 14, traction hooks 15 are fixedly connected to both sides of the slider 2, and threaded seats are fixedly connected to both ends of the mounting frame 1. The threaded seats can be used to fix the float 11, and the output end of the winch 14 is connected to the traction hooks 15 on the same side via a rope.

[0029] In order to facilitate the feeding of material into the material cylinder 4, a feed pipe 16 is fixedly connected to the upper top of the material cylinder 4, and a cone is fixedly connected to the upper top of the feed pipe 16.

[0030] In order to facilitate the flow of water through the net cage body 17, the bottom of the mounting frame 1 is detachably connected to the net cage body 17. The mounting frame 1 and the net cage body 17 are detachably connected by bolts, which facilitates replacement and maintenance. The outer surface of the net cage body 17 is provided with mesh holes.

[0031] In order to facilitate the movement of the winch 14, a push handle 18 is fixedly connected to the outer surface of the base 13, and a grip is fixedly connected to the end of the two push handles 18.

[0032] The specific working process of this utility model is as follows:

[0033] In use, first install the mounting frame 1 and float 11 on top of the net cage body 17 in sequence, and connect the winch 14 and electric push rod 5 to the external power supply. Then, add the prepared fish food into the feed cylinder 4 through the feed pipe 16. At this time, the electric push rod 5 is in the retracted state, and the blocking plate 6 is located at the bottom of the feed cylinder 4, which can tightly seal the bottom opening of the feed cylinder 4. Then, start the winch 14 on the side away from the feed cylinder 4. The output end of the winch 14 rotates, causing the rope connected to the traction hook 15 to wind around the winch 14, driving the slider 2 and... The upper feeding component moves forward. When the lower end of the feed cylinder 4 is directly in front of the feeding area, the winch 14 stops and the electric push rod 5 is turned on. The output end of the electric push rod 5 drives the blocking plate 6 to descend. At this time, the lowermost end of the feeding ring 8 is in contact with the water surface. As the electric push rod 5 continues to descend, the feed in the feed cylinder 4 falls onto the water surface and is trapped inside the feeding ring 8, preventing the fish food from flowing everywhere with the water flow and avoiding waste and pollution of the net cage body 17. After feeding is finished, the winch 14 on the other side is turned on to pull the feeding mechanism back to its original position.
