Description

Technical Field

[0001] This utility model relates to the field of fish feeding equipment, and in particular to a feeding device for fish farming in ponds. Background Technology

[0002] A feeding device for fish farming in ponds is a specialized device for feeding fish in ponds. Its main purpose is to ensure that fish have enough food while improving the efficiency, accuracy, and uniformity of feeding, and minimizing feed waste and water pollution.

[0003] When feeding fish, especially with compound feeds containing multiple ingredients, most equipment may not be able to fully mix the various feed ingredients, requiring manual mixing. This mixing process can lead to stratification, resulting in uneven nutrient distribution in the feed each time the fish eat. This negatively impacts fish growth and development. Furthermore, excessively large feed particles can cause blockages, requiring manual cleaning, which not only interrupts the feeding process but also increases maintenance costs and time, reducing overall feeding efficiency. Fish require different amounts of food at different growth stages; juvenile fish typically need less feed, while adult fish need more. Without quantitative feeding devices, it's difficult to precisely control the amount of feed given each time. Overfeeding can occur, and excess feed that cannot be consumed in time will decompose, consuming oxygen and producing harmful substances like ammonia and nitrogen, leading to water quality deterioration. In the long run, this can cause digestive disorders in the fish, increasing aquaculture costs and labor input. Utility Model Content

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model, through its specially designed mixing mechanism, solves the problems of uneven nutrient composition in fish feed during each feeding, which negatively impacts fish growth and development. It also addresses the issue of excessively large feed particles causing blockages during discharge, requiring manual cleaning. This not only interrupts the feeding process but also increases maintenance costs and time, reducing overall feeding efficiency. Stirring blocks fixed to the inner wall of the connecting plate stir the feed as the connecting plate moves, providing initial agitation and mixing. Simultaneously, the first stirring rod, fixed to the outer side of the first fixed ring in the middle of the first rotating rod, also rotates, and the first stirring rod and stirring blocks are arranged in a cross configuration. Their interaction further increases the complexity and comprehensiveness of feed mixing, ensuring thorough horizontal stirring and mixing of the feed. This prevents feed components from accumulating or separating in certain areas, effectively improving the uniformity of mixing multi-component compound feeds, promoting healthy and uniform fish growth, improving fish meat quality and yield, reducing frequent blockage cleaning, and ensuring the continuity of the feeding process.

[0016] 2. By using a support plate, cylinder, first fixed plate, second motor, second rotating rod, and partition plates, this system addresses the problems of water quality deterioration and potential long-term digestive disorders in fish, increasing aquaculture costs and labor input. Two partition plates form a collection trough to collect feed falling from the support plate. When the trough is full, a command is sent to the cylinder via the partition plates, which in turn controls the second motor to rotate, causing the collection trough (composed of the two partition plates) to rotate as well. Simultaneously, another set of collection troughs rotates to the bottom of the support plate to collect feed again. Once the full collection trough reaches the bottom, two support plates at the bottom form a discharge port to discharge the feed. The feed is discharged through a hopper at the bottom of the tank, effectively feeding the fish. This significantly reduces the complexity of manual operation, saves time and manpower, minimizes the impact of excess feed decomposition on water quality, and lowers feed costs.

[0033] like Figure 1 - Figure 5 As shown: A feeding device for fish farming in a pond includes a top box 1, and a mixing mechanism 2 is provided inside the top box 1;

[0034] The mixing mechanism 2 includes: a first protective box 201, a first motor 202, two connecting plates 205, and two first bevel gears 210. The left side wall of the first protective box 201 is fixedly connected to the right side wall of the top box 1. The top box 1 is used to mix various feeds poured in through the mixing mechanism 2. The first motor 202 is fixedly connected inside the first protective box 201. The output end of the first motor 202 is fixedly connected to a first rotating rod 203. The left end of the first rotating rod 203 is rotatably connected to the left side wall inside the top box 1. The first protective box 201 provides external protection for the first motor 202 and fixes the first motor 202 to the right side wall of the top box 1. The output end of the first motor 202 drives the first rotating rod 203 to rotate. The left end of the first rotating rod 203 is rotatably connected to the left side wall inside the top box 1 to support the first rotating rod 203 and improve the stability of the first rotating rod 203 during rotation.

[0035] Connecting rings 204 are fixedly connected to both the left and right sides of the middle portion of the first rotating rod 203. Two connecting plates 205 are fixedly connected to the front and rear sides of the two connecting rings 204 on both the left and right sides. Stirring blocks 206 are fixedly connected to the inner walls of the two connecting plates 205. A first fixing ring 207 is fixedly connected to the middle portion of the first rotating rod 203. First stirring rods 208 are fixedly connected to the outer sides of the four first fixing rings 207. The four first stirring rods 208 and the multiple stirring blocks 206 are arranged in a crisscross pattern. Connecting plates 204 are fixedly connected to the connecting rings 204 in the middle portion of the first rotating rod 203. 5. As the connecting plate 205 rotates, the stirring block 206 is fixed on the inner wall of the connecting plate 205. The stirring block 206 will stir the feed as the connecting plate 205 moves, playing a preliminary role in turning and mixing the feed. At the same time, the first stirring rod 208 fixed on the outside of the first fixing ring 207 in the middle of the first rotating rod 203 also rotates. The first stirring rod 208 and the stirring block 206 are in a cross state. They cooperate with each other, further increasing the complexity and comprehensiveness of the feed stirring, so that the feed is fully stirred and mixed in the horizontal direction, avoiding the local accumulation or separation of feed components.

[0036] Device boxes 209 are provided on the outer sides of both the left and right ends of the first rotating rod 203. First bevel gears 210 are fixedly connected to the outer sides of both the left and right ends of the first rotating rod 203. The two first bevel gears 210 are set inside the two device boxes 209. Second bevel gears 211 are provided on the front and rear sides of each device box 209. The device boxes 209 are used to protect the first bevel gears 210 and second bevel gears 211 inside from the outside.

[0037] Each first bevel gear 210 meshes with every two second bevel gears 211. Connecting rods 212 are fixedly connected inside the four second bevel gears 211. The other ends of the four connecting rods 212 are rotatably connected to the front and rear side walls of the top box 1. Two second fixing rings 213 are fixedly connected to the outer side of each connecting rod 212. A second stirring rod 214 is fixedly connected to the outer side of every two second fixing rings 213. The first bevel gears 210 at the left and right ends of the first rotating rod 203 rotate synchronously with the first rotating rod 203. Because each first bevel gear 210... The first bevel gear 210 rotates, which meshes with the two second bevel gears 211. When the first bevel gear 210 rotates, it drives the second bevel gear 211 to rotate. The second bevel gear 211 is fixed on the connecting rod 212, thereby driving the connecting rod 212 to rotate. When the connecting rod 212 rotates, the second fixing ring 213 and the second stirring rod 214 fixed on its outer side also start to rotate. The second stirring rod 214 stirs the feed in a direction perpendicular to the first stirring rod 208 and pushes the feed on the left and right sides to move towards the center, so that the feed can be fully stirred to improve the uniformity of mixing.

[0038] The top box 1 has a bottom box 3 at its bottom, which provides external protection for the internal devices. The top of the top box 1 is rotatably connected to a top cover 4, and a sealing ring 5 is fixedly connected to the bottom wall of the top cover 4. The sealing ring 5 is located on the inner top wall of the top box 1. By opening the top cover 4, the top of the top box 1 can be opened to pour various feeds into the interior of the top box 1 for mixing. In addition, through the sealing ring 5 at the bottom of the top cover 4, after the top cover 4 is closed, the sealing ring 5 will insert into the interior of the top box 1, which can effectively seal the interior of the top box 1.

[0039] An observation window 6 is fixedly connected to the front side wall of the top box 1, allowing personnel to observe the internal situation from the outside. A control panel 13 is fixedly connected to the right side wall of the top box 1, allowing control of the entire device.

[0040] A guide plate 7 is fixedly connected to the bottom wall of the top box 1. A guide rail groove 8 is opened inside the bottom wall of the guide plate 7. A baffle 9 is slidably connected inside the guide rail groove 8. A handle 10 is fixedly connected to the left side wall of the baffle 9. The outer side of the handle 10 is connected through a slot in the left side wall of the bottom box 3. The guide plate 7 guides the feed inside the top box 1. When the feed is mixed, the baffle 9 is placed in the guide rail groove 8 inside the guide plate 7 to block the feed outlet and prevent the feed from falling during mixing. After mixing, the operator pulls the handle 10 to remove the baffle 9 from the guide rail groove 8 at the bottom of the guide plate 7, and the feed will fall into the bottom box 3.

[0041] A support frame 11 is fixedly connected to the bottom of the bottom box 3, and a feed hopper 12 is fixedly connected to the bottom wall of the bottom box 3. The support frame 11 provides bottom support for the entire device. When the device is placed next to the fish pond, the feed inside the device will be discharged through the feed hopper 12 to feed the fish.

[0042] like Figure 8 - Figure 10 As shown, the inner walls of the bottom box 3 are all fixedly connected with support plates 15, and the inner walls of the two support plates 15 are fixedly connected with cylinders 16. The two support plates 15 are used to support and fix the inner cylinders 16 at both ends.

[0043] Both sides of the two support plates 15 are threaded with first fixing discs 18, and the other side of the two first fixing discs 18 is threaded with a fixing device 19. The right side wall of the bottom box 3 is fixedly connected with a second protective box 14, and a second motor 20 is installed inside the second protective box 14. The upper, lower, front and rear sides of the cylinder 16 are fixedly connected with support plates 17. The output end of the second motor 20 is fixedly connected with a second rotating rod 21. The left and right ends of the second rotating rod 21 are rotatably connected to the inside of the two fixing devices 19. The middle part of the second rotating rod 21 is located inside the cylinder 16. When the second motor 20 starts to work, the second motor 20 drives the second rotating rod 21 to rotate. Since the left and right ends of the second rotating rod 21 are rotatably connected to the inside of the fixing device 19, and the fixing device 19 is threadedly connected to the support plate 15 through the first fixing disc 18 and fixed in the bottom box 3, it provides support and positioning for the stable rotation of the second rotating rod 21. In addition, the two support plates 17 at the top form a feed inlet, allowing the mixed feed to flow into the inside of the cylinder 16 through the support plates 17.

[0044] like Figure 10 - Figure 12 As shown, a connecting column 22 is fixedly connected to the outer side of the second rotating rod 21, and a partition plate 23 is fixedly connected to the outer side of each connecting column 22. The connecting column 22 on the outer side of the second rotating rod 21 is connected to the partition plate 23, and drives the partition plate 23 to rotate. In addition, a set of collection troughs is formed by every two partition plates 23. The feed inside the cylinder 16 will enter the collection trough formed by the two partition plates 23.

[0045] Each of the five partition plates 23 has a second fixing plate 24 fixedly connected to both sides. The second fixing plates 24, positioned on either side of the partition plates 23, act as barriers to prevent feed from falling out of the partition plates 23. The five partition plates 23 are rotatably connected to the inside of the cylinder 16. Each partition plate 23 has a sensor 25 fixedly connected to its inner wall. When the collection trough is full, the sensor 25 on the partition plate 23 sends a message to the control panel 13, which then controls the second motor 20 to rotate. This rotates the collection trough consisting of two partition plates 23, while another set of collection troughs rotates to the bottom of the support plate 17 to collect feed again. When the full collection trough rotates to the bottom, the two support plates 17 at the bottom form a discharge port to discharge the feed. The feed is discharged through the discharge hopper 12 at the bottom of the bottom box 3, thus feeding the fish.

[0046] It should be noted that this utility model is a feeding device for fish farming in a pond. First, the first motor 202, the second motor 20, the control panel 13 and the sensor 25 are connected to an external power source to supply power to the device.

[0047] After various feeds are poured into the top of the top box 1 through the top cover 4, the first motor 202 is started during mixing. The first motor 202 drives the first rotating rod 203 to rotate, and the connecting plate 205 fixedly connected to the connecting ring 204 in the middle of the first rotating rod 203 rotates accordingly. Since there are stirring blocks 206 fixed on the inner wall of the connecting plate 205, these stirring blocks 206 will stir the feed with the movement of the connecting plate 205, playing a preliminary role in turning and mixing the feed. At the same time, the first stirring rod 208 fixed on the outside of the first fixing ring 207 in the middle of the first rotating rod 203 also rotates, and the first stirring rod 208 and the stirring blocks 206 are in a cross state. They cooperate with each other, further increasing the complexity and comprehensiveness of feed mixing, so that the feed is fully stirred and mixed in the horizontal direction, avoiding local accumulation or separation of feed components.

[0048] The first bevel gears 210 at both ends of the first rotating rod 203 rotate synchronously with the first rotating rod 203. Since each first bevel gear 210 meshes with two second bevel gears 211, when the first bevel gear 210 rotates, it drives the second bevel gears 211 to rotate. The second bevel gears 211 are fixed on the connecting rod 212, thereby driving the connecting rod 212 to rotate. When the connecting rod 212 rotates, the second fixing ring 213 and the second stirring rod 214 fixed on its outer side also begin to rotate. These second stirring rods 214 stir the feed in a direction perpendicular to the first stirring rod 208, so that the feed can be mixed in different spatial dimensions. In this way, through the stirring in one direction by the first rotating rod 203 and its associated stirring components, and the stirring in another direction by the connecting rod 212 and its associated stirring components driven by the first bevel gears 210 and the second bevel gears 211, the feed can achieve all-round and multi-level mixing, and push the feed on the left and right sides towards the center.

[0049] After the feed is mixed, it falls into container 16 inside the base 3, and the second motor 20 starts working. The second motor 20 drives the second rotating rod 21 to rotate. Since the left and right ends of the second rotating rod 21 are rotatably connected inside the fixture 19, and the fixture 19 is threadedly connected to the support plate 15 through the first fixing plate 18 and fixed inside the base box 3, it provides support and positioning for the stable rotation of the second rotating rod 21.

[0050] In addition, the two support plates 15 and the first fixed plate 18 and the fixture 19 connected to them provide a stable support structure for the cylinder 16 and the second rotating rod 21, ensuring the mechanical stability of the entire device during operation and preventing displacement or shaking of the cylinder 16 and rotating parts.

[0051] When the device starts running, the mixed feed enters the cylinder 16 through the feed inlet formed by the two upper support plates 17. At this time, the second motor 20 located in the second protection box 14 starts, and its output end drives the second rotating rod 21 to start rotating. The connecting column 22 on the outside of the second rotating rod 21 rotates with it, thereby causing the partition plate 23 fixed on the connecting column 22 to rotate synchronously inside the cylinder 16.

[0052] Additionally, two partition plates 23 form a collection trough to collect feed falling from the support plate 17. When the collection trough is full, a sensor 25 on the partition plate 23 sends information to the control panel 13, which then controls the second motor 20 to rotate, causing the collection trough formed by the two partition plates 23 to rotate. Simultaneously, another set of collection troughs rotates to the bottom of the support plate 17 to collect feed again. When the full collection trough rotates to the bottom, the two support plates 17 at the bottom form a discharge port to discharge the feed. During discharge, the feed is discharged through the discharge hopper 12 at the bottom of the bottom box 3, thus feeding the fish.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
