Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of feeding devices, specifically a fish fry feeding device. Background Technology
[0002] In the aquaculture industry, the fry rearing stage is particularly crucial, as it largely determines the overall efficiency of the entire aquaculture process. The survival rate and growth quality of the fry are key indicators of successful rearing, directly impacting the scale and profitability of subsequent adult fish farming. If the fry are properly reared, with high survival rates and healthy growth, the yield and quality of adult fish will correspondingly increase, leading to higher economic benefits. Conversely, if problems arise during fry rearing, resulting in low survival rates or poor growth, even significant resources and effort invested in adult fish farming will be insufficient to compensate for the initial losses, ultimately affecting the profitability of the entire aquaculture industry. Therefore, aquaculture operators must highly value this critical fry rearing stage, ensuring the healthy growth of fry through scientific management and technological innovation, laying a solid foundation for the sustainable development of the entire aquaculture industry.
[0003] The existing technology has the following problems: Usually, feeding machines are used to feed fish. However, if the feed clumps in the feeding machine, it can easily block the discharge port, causing feeding to be interrupted, affecting the fish fry's normal feeding, and thus affecting their growth rate and survival rate. In addition, cleaning up the clumps of feed increases labor costs and work difficulty, reducing the overall aquaculture efficiency.
[0004] Therefore, this utility model provides a fish fry feeding device to solve the above problems. Utility Model Content
[0005] This invention provides a fish fry feeding device, which aims to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: including a storage bin and an anti-caking structure assembled inside the storage bin, and an anti-clogging structure disposed below the storage bin;
[0007] The anti-caking structure includes a servo motor fixedly installed on the top surface of the storage tank, a fixed rod that runs through the top and bottom of the storage tank and is fixedly connected to the output end of the servo motor, and three U-shaped rods distributed in a circumferential array on the surface of the fixed rod. A rectangular plate is fixedly connected to the surface of the U-shaped rods near the inner bottom wall of the storage tank.
[0008] As a preferred technical solution of this application, the storage tank has an opening for feeding on one side of the top and a discharge port for discharging on one side of the bottom.
[0009] As a preferred technical solution of this application, the top surface of the rectangular plate is provided with rounded corners on both sides and the bottom is slidably connected to the inner bottom wall of the storage tank, and the rectangular plate can completely cover the discharge port.
[0010] As a preferred technical solution of this application, the anti-clogging structure includes a disc fixedly connected to one end of the bottom of the storage tank by a fixed rod and a fixed column fixedly connected to the surface of the disc, as well as a stirring rod installed inside the discharge port, wherein a connecting rod is fixedly connected to the bottom of the stirring rod.
[0011] As a preferred technical solution of this application, the bottom of the fixed column is connected to the connecting rod and fixedly connected to the anti-detachment block, and a ring is slidably connected to one side of the surface of the connecting rod and rotatably connected to the bottom of the storage tank through a bearing.
[0012] As a preferred technical solution of this application, it also includes a guide frame fixedly connected to the bottom outlet of the storage tank and support legs fixedly connected to both sides of the bottom surface of the storage tank.
[0013] As a preferred technical solution of this application, an inclined plate is fixedly connected to the surface of the guide frame, a dispersing plate is fixedly connected to the surface of the inclined plate, and a rectangular rod for dispersing feed is fixedly connected to one side of the dispersing plate and located on one side of the surface of the inclined plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] By using an anti-caking feature, the servo motor is turned on and drives the fixed rod to rotate, causing the U-shaped rod and rectangular plate to rotate synchronously inside the storage bin. When the U-shaped rod is driven by the fixed rod, it can break up the clumps of feed inside the bin. The rectangular plate slides along the bottom of the bin, which can move the feed at the bottom of the storage bin. The opening and closing of the discharge port can also be controlled by rotation. The rounded corner design reduces the feed from being crushed. No manual stirring is required when discharging, which reduces labor costs and workload.
[0016] By employing an anti-clogging structure, the fixed column rotates with the disc, which in turn drives the stirring rod to reciprocate within the discharge port via a connecting rod. This effectively prevents feed from accumulating at the outlet, ensuring a smooth feeding process and significantly reducing clogging at the discharge port, thereby improving discharge efficiency.

[0023] 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.
[0024] This utility model provides, for example Figure 1-5 The fish fry feeding device shown includes a storage tank 1, an anti-caking structure 2 assembled inside the storage tank 1, and an anti-clogging structure 3 disposed below the storage tank 1.
[0025] The anti-caking structure 2 includes a servo motor 201 fixedly installed on the top surface of the storage tank 1, a fixed rod 202 that penetrates the top and bottom of the storage tank 1 and is fixedly connected to the output end of the servo motor 201, and three U-shaped rods 203 distributed in a circumferential array on the surface of the fixed rod 202. A rectangular plate 204 is fixedly connected to the surface of the U-shaped rods 203 near the inner bottom wall of the storage tank 1.
[0026] Using the above scheme, the servo motor 201 is turned on and the fixed rod 202 is driven to rotate, which drives the U-shaped rod and the rectangular plate 204 to rotate synchronously in the storage bucket 1. When the U-shaped rod is driven by the fixed rod 202, it can break up the clumps of feed in the bucket. The rectangular plate 204 slides along the bottom of the bucket, which can drive the feed at the bottom of the storage bucket 1. The opening and closing of the discharge port can also be controlled by rotation.
[0027] The storage hopper 1 has an opening for feeding on one side of its top and an outlet for discharging on one side of its bottom. The rectangular plate 204 has rounded corners on both sides of its top surface and is slidably connected to the inner bottom wall of the storage hopper 1. The rectangular plate 204 can completely cover the outlet. The anti-clogging structure 3 includes a disc 301 fixedly connected to a fixing rod 202 penetrating one end of the bottom of the storage hopper 1, a fixing post 302 fixedly connected to the surface of the disc 301, and a stirring rod 303 mounted inside the outlet. The bottom of the stirring rod 303 is fixedly connected to a connecting... The bottom of the rod 304 and the fixed column 302 pass through the connecting rod 304 and are fixedly connected to the anti-detachment block. A ring 305 is slidably connected to one side of the surface of the connecting rod 304 and is rotatably connected to the bottom of the storage tank 1 through a bearing. It also includes a guide frame 4 fixedly connected to the bottom of the storage tank 1 below the discharge port and support legs 5 fixedly connected to both sides of the bottom surface of the storage tank 1. An inclined plate 6 is fixedly connected to the surface of the guide frame 4. A dispersing plate 7 is fixedly connected to the surface of the inclined plate 6. A rectangular rod for dispersing feed is fixedly connected to one side of the dispersing plate 7 and is located on one side of the surface of the inclined plate 6.
[0028] Using the above scheme, the rectangular plate 204 can be controlled by the servo motor 201 to block the discharge port, thereby controlling the discharge amount. When the discharge reaches a certain amount, the servo motor 201 flips, causing the rectangular plate 204 to block the discharge port, thus stopping the discharge. At the same time, the fixed column 302 rotates with the disc 301, causing the connecting rod 304 to slide on the surface of the ring 305. The ring 305 rotates at the bottom of the storage tank 1 through a bearing, making the movement of the connecting rod 304 more stable. This, in turn, drives the stirring rod to reciprocate at the discharge port, preventing feed from clogging at the outlet and ensuring smooth feeding. The combination of the guide frame 4, the inclined plate 6, and the dispersing plate 7 can evenly disperse the feed to the seedling area, reducing local accumulation.
[0029] The working principle of a fish fry feeding device based on an embodiment is as follows: When in use, fish fry feed is first added through the opening at the top of the storage bin 1, and the support legs 5 stably support the device. The servo motor 201 is started, driving the fixed rod 202 to rotate, which in turn causes the U-shaped rod and rectangular plate 204 to rotate inside the storage bin 1. The U-shaped rod breaks up clumps of feed inside the bin, and the rectangular plate 204 slides along the bottom of the bin, its rounded top corners reducing breakage during feed mixing.
[0030] When the rectangular plate 204 rotates away from the discharge port, the feed falls from the discharge port. After the required feeding amount is reached, the q drives the servo motor 201 to reverse, causing the rectangular plate 204 to rotate back and completely cover the discharge port, stopping the discharge.
[0031] Simultaneously, the fixing rod 202 drives the bottom disc 301 to rotate, and the fixing post 302 on the disc 301 rotates with it, causing the connecting rod 304 to slide on the surface of the ring 305. The ring 305 rotates at the bottom of the storage tank 1 through the bearing, ensuring the smooth movement of the connecting rod 304, which in turn drives the stirring rod 303 to reciprocate and stir in the discharge port, preventing the accumulation of feed and the falling feed enters the inclined plate 6 through the guide frame 4, and is dispersed under the action of the dispersing plate 7 and the rectangular rod, and finally falls into the seedling area.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
