Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquatic product salvage technology, specifically to a smart aquatic product salvage device. Background Technology
[0002] Aquaculture is a production activity involving the breeding, cultivation, and harvesting of aquatic plants and animals under human control. It generally includes the entire process from seedling to marketable aquatic products under artificial feeding and management. In a broader sense, it can also include aquatic resource enhancement. Aquaculture includes extensive farming, intensive farming, and high-density intensive farming. Extensive farming involves releasing seedlings into small to medium-sized natural water bodies and relying entirely on natural feed to raise aquatic products, such as fish farming in lakes and reservoirs and shellfish farming in shallow seas. Intensive farming uses feeding and fertilization methods in smaller bodies of water to raise aquatic products, such as pond fish farming, cage fish farming, and enclosure aquaculture. High-density intensive farming uses methods such as flowing water, temperature control, aeration, and feeding high-quality feed to achieve high yields in small bodies of water, such as high-density flowing water fish and shrimp farming.
[0003] Current methods for harvesting aquatic organisms mainly rely on manual methods using nets. After use, these nets require manual handling, and due to their large size, the process is cumbersome and inconvenient to carry. Furthermore, during the retrieval process, existing mechanical devices often cause the nets to come into direct contact with the edges or transmission components of the equipment, resulting in wear and tear or even tearing of the nets. This leads to a high probability of net damage. Utility Model Content
[0004] To solve the above-mentioned technical problems, a smart aquatic product harvesting device is provided, which solves the problems of inconvenience in sorting and high probability of wear and tear on fishing nets.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A smart aquatic product harvesting device includes a main body. A through groove is formed on the front of the main body. A first rotating rod and a second rotating rod are rotatably mounted on the inner wall of the through groove. A rotating groove is formed inside the main body corresponding to the through groove. First side plates are fixedly mounted on both the front and rear sides of the main body. A first rotating shaft is disposed between two of the first side plates. A conveyor belt is fitted onto the outer surface of the first rotating shaft. A second side plate corresponding to the first side plate is fixedly mounted on the right side of the main body. A second rotating shaft is rotatably mounted between two of the second side plates. A conveyor belt is fitted onto the outer surface of the second rotating shaft. A plurality of feeding hoppers are fixedly mounted on the surface of the conveyor belt, and the plurality of feeding hoppers are linearly distributed along the edge of the conveyor belt.
[0007] Preferably, the first rotating rod and the second rotating rod have the same structure, and a plurality of insertion rods are fixedly installed on the outer surface of the first rotating rod, and the plurality of insertion rods are circumferentially distributed about the center line of the first rotating rod.
[0008] Preferably, two first hydraulic rods are fixedly installed on the front of the main body corresponding to the first rotating rod, and a reversing rod is provided between the two first hydraulic rods. The reversing rod is rotatably connected to both first hydraulic rods.
[0009] Preferably, a driven gear is rotatably mounted on the top of the inner wall of the rotating groove. The driven gear is fixedly connected to the first rotating rod. A driving gear is provided inside the rotating groove corresponding to the driven gear, and the driving gear is meshed with the driven gear. The driving gear is rotatably connected to the bottom of the inner wall of the rotating groove through the first connecting rod.
[0010] Preferably, a second connecting rod is rotatably mounted on the top of the inner wall of the rotating groove corresponding to the driven gear, a ratchet is fixedly mounted on the outer surface of the second connecting rod, the second connecting rod is fixedly connected to the second rotating rod, and a transmission belt is sleeved on the outer surface of the second connecting rod.
[0011] Preferably, a fixing rod is fixedly installed at the bottom of the inner wall of the rotating groove corresponding to the ratchet, and a pawl corresponding to the ratchet is sleeved on the outer surface of the fixing rod.
[0012] Preferably, a base plate is fixedly installed at the bottom of the inner wall of the rotating groove corresponding to the pawl, and a second hydraulic rod is rotatably installed on the side of the base plate corresponding to the pawl. The end of the second hydraulic rod near the pawl is rotatably connected to the surface of the pawl, and a spring is sleeved on the outer surface of the second hydraulic rod. The two ends of the spring are fixedly connected to the side of the base plate and the surface of the pawl, respectively.
[0013] Compared with the prior art, the advantages of this utility model are as follows: This utility model sets up a first rotating rod and a second rotating rod. The first rotating rod serves as the carrier of the fishing net. When the fishing net is not in use, the first rotating rod stores the fishing net. When the fishing net is in use, the first rotating rod reverses to allow the fishing net to slowly detach from the first rotating rod. Workers use the fishing net to surround the pond to be fished and wrap the fishing net around the second rotating rod. The first rotating rod rotates forward to roll up the fishing net, completing the fishing of fish in the pond while simultaneously organizing the fishing net. This utility model also sets up a first hydraulic rod and a reversing rod. When the equipment stores the fishing net, the first hydraulic rod unfolds, causing the reversing rod to push the fishing net, thereby keeping the fishing net away from the sharp corners or transmission components of the equipment, thus preventing the fishing net from being worn or even torn, and reducing the probability of wear and tear on the fishing net.

Detailed Implementation
[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0020] Reference Figure 1-4As shown, a smart aquatic product harvesting device includes a main body 1. A through groove 2 is formed on the front of the main body 1. A first rotating rod 3 and a second rotating rod 4 are rotatably mounted on the inner wall of the through groove 2. A rotating groove 5 is formed inside the main body 1 corresponding to the through groove 2. First side plates 6 are fixedly mounted on both the front and rear sides of the main body 1. A first rotating shaft 7 is arranged between the two first side plates 6. A conveyor belt 8 is sleeved on the outer surface of the first rotating shaft 7. A second side plate 9 corresponding to the first side plate 6 is fixedly mounted on the right side of the main body 1. A second rotating shaft 10 is rotatably mounted between the two second side plates 9. A conveyor belt 11 is sleeved on the outer surface of the second rotating shaft 10. A plurality of feeding hoppers 12 are fixedly mounted on the surface of the conveyor belt 11. Linearly distributed along the edge of conveyor belt 11, both the first rotating shaft 7 and the second rotating shaft 10 are externally powered. A fishing net is installed on the outer surface of the first rotating rod 3 (this is existing technology and will not be described in detail here). The worker pulls the fishing net and connects the other end of the net to the second rotating rod 4. The second rotating rod 4 rotates several times and then stops rotating. The first rotating rod 3 rotates so that the fishing net is wrapped around it. As the fishing net shrinks, the fish in the pond gather in one place. Then, the second rotating shaft 10 rotates so that the fish leave the pond with the feeding hopper 12 and enter the surface of the conveyor belt 8. The first rotating shaft 7 rotates so that the fish on the surface of the conveyor belt 8 move, thus completing the harvesting of fish in the pond.
[0021] like Figure 1-2 As shown, the first rotating rod 3 and the second rotating rod 4 have the same structure. Several insertion rods 13 are fixedly installed on the outer surface of the first rotating rod 3. The insertion rods 13 are circumferentially distributed about the center line of the first rotating rod 3. The spacing of the insertion rods 13 corresponds to the mesh of the fishing net, which improves the firmness of the connection between the first rotating rod 3 and the fishing net, and at the same time cleans the mesh of the fishing net, making it convenient for the next use of the fishing net.
[0022] like Figure 1 As shown, two first hydraulic rods 14 are fixedly installed on the front of the main body 1 corresponding to the first rotating rod 3. A reversing rod 15 is provided between the two first hydraulic rods 14. The reversing rod 15 is rotatably connected to both first hydraulic rods 14. During the process of dredging the pond, the first hydraulic rods 14 unfold, causing the reversing rod 15 to push the fishing net, thereby changing the direction in which the fishing net enters the first rotating rod 3, preventing friction between the fishing net and the edges of the equipment, and thus protecting the fishing net.
[0023] like Figure 3-4As shown, a driven gear 16 is rotatably mounted on the top of the inner wall of the rotating groove 5. The driven gear 16 is fixedly connected to the first rotating rod 3. A driving gear 17 is provided inside the rotating groove 5 corresponding to the driven gear 16, and the driving gear 17 is meshed with the driven gear 16. The driving gear 17 is rotatably connected to the bottom of the inner wall of the rotating groove 5 through the first connecting rod 18. The first connecting rod 18 is fixedly connected to the driving gear 17. The first connecting rod 18 is externally connected to a brushless motor. The first connecting rod 18 drives the driven gear 16 to rotate through the driving gear 17. The number of teeth of the driving gear 17 is less than that of the driven gear 16, thereby increasing the torque of the first rotating rod 3.
[0024] like Figure 3-4 As shown, a second connecting rod 19 is rotatably mounted on the top of the inner wall of the rotating groove 5 corresponding to the driven gear 16. A ratchet 20 is fixedly mounted on the outer surface of the second connecting rod 19. The second connecting rod 19 is fixedly connected to the second rotating rod 4. A transmission belt 21 is sleeved on the outer surface of the second connecting rod 19. A brushless motor is connected to the second connecting rod 19. The second connecting rod 19 drives the ratchet 20 to rotate through the transmission belt 21, and the ratchet 20 drives the second connecting rod 19 to rotate.
[0025] like Figure 3-4 As shown, a fixed rod 22 is fixedly installed at the bottom of the inner wall of the rotating groove 5 corresponding to the ratchet 20. A pawl 23 corresponding to the ratchet 20 is sleeved on the outer surface of the fixed rod 22. The pawl 23 and the ratchet 20 cooperate with each other. By utilizing the unidirectional transmission characteristics of the ratchet 20 mechanism, the second rotating rod 4 remains stationary when the first rotating rod 3 is winding up the fishing net.
[0026] like Figure 3-4 As shown, a base plate 24 is fixedly installed at the bottom of the inner wall of the rotating groove 5 corresponding to the pawl 23. A second hydraulic rod 25 is rotatably installed on the side of the base plate 24 corresponding to the pawl 23. One end of the second hydraulic rod 25 near the pawl 23 is rotatably connected to the surface of the pawl 23. A spring 26 is sleeved on the outer surface of the second hydraulic rod 25. The two ends of the spring 26 are fixedly connected to the side of the base plate 24 and the surface of the pawl 23, respectively. When the fish in the fishing net are caught, the second hydraulic rod 25 retracts, causing the pawl 23 to leave the ratchet 20, thereby causing the fishing net on the second rotating rod 4 to detach after the second rotating rod 4 reverses.
[0027] Working principle: After the operator places the equipment in a suitable position, the fishing net on the first rotating rod 3 is driven to circle the pond to be harvested and connected to the second rotating rod 4. The second connecting rod 19 rotates to cause part of the fishing net to wrap around the second rotating rod 4. At the same time, the first hydraulic rod 14 extends to support the fishing net with the reversing rod 15. Then, the first connecting rod 18 drives the driven gear 16 to rotate through the driving gear 17, so that the first rotating rod 3 rolls up the fishing net. As the fishing net shrinks, the fish in the pond gather in one place. Then, the second rotating shaft 10 rotates to make the fish leave the pond with the feeding hopper 12 and enter the surface of the conveyor belt 8. The first rotating shaft 7 rotates to make the fish on the surface of the conveyor belt 8 move, thus completing the harvesting of the fish in the pond. After the fish are harvested, the second hydraulic rod 25 retracts, causing the pawl 23 to disengage from the ratchet 20, so that the second rotating rod 4 reverses and the fishing net on the second rotating rod 4 is released, thus completing the harvesting.
