Description

Technical Field

[0001] This utility model relates to the field of fish catch sorting, specifically a novel fish catch sorting device. Background Technology

[0002] After the fish are caught, they undergo different processing methods depending on their size. Therefore, the fish need to be sorted. The sorting methods are generally manual sorting or sorting equipment. In order to improve the sorting efficiency, most processing plants have adopted sorting equipment to sort the fish.

[0003] In existing fish sorting devices, the conveyor mechanism transports fish to the sorting net. Smaller fish pass directly through the sorting holes in the net and fall into the first fish box below, while larger fish remain on the net. To facilitate the collection of larger fish above the net, the net is usually tilted and a vibration motor is installed. The motor drives the net to vibrate, or a vibration mechanism is installed to make the net slide up and down, allowing the larger fish to slide down the tilted net into the second fish box. However, using the vibration of the net to accelerate the sliding of larger fish can cause stress in the fish, leading to increased respiratory rate, decreased immunity, and increased susceptibility to bacterial infections (such as bacterial gill rot). This has a greater impact on live fish transportation or temporary holding scenarios. Therefore, we propose a new type of fish sorting device. Utility Model Content

[0004] The purpose of this utility model is to provide a novel fish sorting device, including a sorting frame, which is inclinedly arranged above a water tank. Several sorting holes are opened through the sorting frame. The inner surface of the sorting frame is smooth, and the inner wall of the sorting holes is smooth. A water pump is fixedly installed on the outer wall of the sorting frame. The water inlet of the water pump is connected to a water pumping pipe, which is fixedly connected to and connected to the water tank. The water outlet of the water pump is connected to a water outlet pipe, and two rows of nozzles are installed on the water outlet pipe.

[0005] Preferably, four sets of fixing seats are fixedly connected to the outer wall of the water outlet pipe, and all four sets of fixing seats are fixedly installed on the top of the sorting frame.

[0006] Preferably, a protective net is provided at the end of the water pump that connects to the water tank.

[0007] Preferably, the inner wall of the water tank is fixedly connected to a partition, and the partition has several water passage holes, which divide the inner cavity of the water tank into a small fish cavity and a large fish cavity.

[0008] Preferably, a drain pipe is installed through the inside of the water tank, a protective net is provided at one end of the drain pipe inside the water tank, and a valve is connected to the other end of the drain pipe.

[0009] Preferably, several support rods are fixedly installed on both outer walls of the sorting frame, and several fixing frames are fixedly installed on both outer walls of the water tank, with each fixing frame fixedly connected to a set of support rods on the outer wall.

[0010] Preferably, the bottom of the water tank is fixedly connected to several support legs, and the bottom of the support legs is flush with the bottom of the support rod.

[0011] Preferably, a fish outlet frame is fixedly connected to the water tank, the inner cavity of the fish outlet frame is interconnected with the small fish cavity, a gate is slidably inserted into the inner side of the fish outlet frame, and the outer surface of the gate is coated with an epoxy resin coating.

[0012] Preferably, the second fish outlet frame is fixedly connected to the water tank, the inner cavity of the second fish outlet frame is interconnected with the large fish cavity, a second gate is slidably inserted into the inner side of the second fish outlet frame, and the outer surface of the second gate is coated with an epoxy resin coating.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In the sorting process of this utility model, fish can slide down the inclined surface inside the sorting frame. Due to the smooth surface treatment of the inner surface of the sorting frame, the friction between the fish and the sorting frame is small, which will not cause great wear to the outer surface of the fish. The inner wall of the sorting hole is also smooth, so that when small fish pass through the sorting hole during the sorting process, the inner wall of the sorting hole will not cause great wear to the outer surface of the fish. In addition, water spraying during sorting can increase the lubrication between the fish and the sorting frame, promote the fish to slide down the sorting frame, and further reduce the damage caused by friction between the fish and the sorting frame.

[0015] 2. When spraying water during sorting, this utility model can not only increase the lubrication between the fish and the sorting frame and promote the fish to slide down the sorting frame, but also allow the fish to come into contact with water during sorting. This keeps the mucus layer on the fish's body surface (the fish's natural protective barrier) from drying out and breaking, preventing the invasion of pathogens and improving the survival rate of the fish during sorting.

[0016] 3. When using this utility model, an appropriate amount of water is added to the water tank. The water in the water tank can provide a living space for the sorted fish. When the large fish and small fish fall into the small fish cavity and the large fish cavity respectively, the water can reduce the damage to the fish when they fall. The water in the water tank can provide a water source for the water spraying work of sorting. The sprayed water will eventually flow back into the water tank. Attached Figure Description

[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] Reference Figure 1 - Figure 5 This utility model discloses a novel fish sorting device, comprising a sorting frame 1, which is inclinedly disposed above a water tank 2. The sorting frame 1 has several sorting holes 3 extending through it. The inner surface of the sorting frame 1 is smooth, and the inner walls of the sorting holes 3 are smooth. A water pump 4 is fixedly installed on the outer wall of the sorting frame 1. The inlet end of the water pump 4 is connected to a water suction pipe 5, which is fixedly connected to and connected to the water tank 2. The outlet end of the water pump 4 is connected to an outlet pipe 6, and two rows of nozzles 7 are connected and installed on the outlet pipe 6.

[0025] Four sets of fixing seats 8 are fixedly connected to the outer wall of the water outlet pipe 6. All four sets of fixing seats 8 are fixedly installed on the top of the sorting frame 1. The four sets of fixing seats 8 make the installation structure between the water outlet pipe 6 and the sorting frame 1 stable. The fixing seats 8 are installed on the top of the sorting frame 1 by bolts and nuts and can be disassembled. The fixing seats 8 are also installed on the outer wall of the water outlet pipe 6 by bolts and nuts and can be disassembled.

[0026] A protective net is installed at one end of the water pumping pipe 5 that is connected to the water tank 2; the protective net on the water pumping pipe 5 can prevent the fish in the small fish cavity 11 from entering the water pumping pipe 5 when the water pumping pipe 5 is pumping water.

[0027] The inner wall of the water tank 2 is fixedly connected to a partition 9, and a plurality of water passage holes 10 are provided through the partition 9. The partition 9 divides the inner cavity of the water tank 2 into a small fish cavity 11 and a large fish cavity 12. The partition 9 can prevent small fish in the small fish cavity 11 from swimming into the large fish cavity 12, and at the same time prevent large fish in the large fish cavity 12 from swimming into the small fish cavity 11. The plurality of water passage holes 10 provided through the partition 9 can allow the water in the large fish cavity 12 and the small fish cavity 11 to communicate with each other. The water passage holes 10 have a small diameter to prevent fish from passing through.

[0028] A drain pipe 13 is installed through the inner side of the water tank 2. A protective net is provided at one end of the drain pipe 13 within the inner cavity of the water tank 2, and the other end of the drain pipe 13 is connected to a valve 14. During use, as the number of fish in the water tank increases, if the water in the water tank 2 is about to overflow, the valve 14 is opened, and a suitable amount of water is discharged from the water tank 2 through the drain pipe 13. The protective net on the drain pipe 13 prevents fish from the large fish cavity 12 from entering the suction pipe 5 during drainage.

[0029] Several support rods 15 are fixedly installed on both outer walls of the sorting frame 1, and several fixing frames 16 are fixedly installed on both outer walls of the water tank 2. Each fixing frame 16 is fixedly connected to a set of support rods 15 on the outer wall. The support rods 15 provide strong support for the sorting frame 1, and the fixing frames 16 ensure a stable connection between the water tank 2 and the support rods 15, thereby making the sorting frame 1 stably positioned above the water tank 2. The fixing frames 16 are fixedly welded to the outer wall of the water tank 2 and are installed on the outer wall of the support rods 15 using bolts and nuts, making it easy to separate the support rods 15 and the fixing frames 16.

[0030] Several support legs 17 are fixedly connected to the bottom of the water tank 2. The bottom of the support legs 17 is flush with the bottom of the support rod 15. The support legs 17 can provide strong support for the water tank 2. And the fact that the bottom of the support legs 17 is flush with the bottom of the support rod 15 allows the entire device to be placed stably on the ground.

[0031] Fish outlet frame 18 is fixedly connected to the water tank 2. The inner cavity of the fish outlet frame 18 is interconnected with the small fish cavity 11. A gate 19 is slidably inserted into the inner side of the fish outlet frame 18. The outer surface of the gate 19 is coated with an epoxy resin coating. After the fish catch is sorted, the gate 19 is pulled out upwards, so that the small fish in the small fish cavity 11 can be discharged from the fish outlet frame 18. The outer surface of the gate 19 is coated with an epoxy resin coating. The epoxy resin coating has extremely strong sealing and corrosion resistance and can form a dense film layer, thereby maintaining good sealing between the gate 19 and the fish outlet frame 18.

[0032] Fish outlet frame 20 is fixedly connected to the water tank 2. The inner cavity of the fish outlet frame 20 is interconnected with the large fish cavity 12. A gate 21 is slidably inserted into the inner side of the fish outlet frame 20. The outer surface of the gate 21 is coated with an epoxy resin coating. After the catch sorting is completed, the gate 21 is pulled out upwards, so that the large fish in the large fish cavity 12 can be discharged from the fish outlet frame 20. The outer surface of the gate 21 is coated with an epoxy resin coating. The epoxy resin coating has extremely strong sealing and corrosion resistance and can form a dense film layer, thereby maintaining good sealing between the gate 21 and the fish outlet frame 20.

[0033] The working principle of this utility model is as follows: When in use, add an appropriate amount of water to the water tank 2 and add oxygen to the water tank 2 through an external aerator; transport the fish to the sorting frame 1 through the fish transport mechanism and place the fish in the sorting frame 1 so that the fish can slide down the inclined surface inside the sorting frame 1. Since the inner surface of the sorting frame 1 is smooth, the friction between the fish and the sorting frame 1 is small, and it will not cause great wear to the outer surface of the fish. In addition, the inner wall of the sorting hole 3 is smooth, so that when small fish pass through the sorting hole 3 during the sorting process, the inner wall of the sorting hole 3 will not cause great wear to the outer surface of the fish.

[0034] As the fish slide down the inclined sorting frame 1, small fish will pass through the sorting hole 3 and fall directly into the small fish cavity 11 below, while large fish will slide down the sorting frame 1 and fall into the large fish cavity 12. At the same time, the water pump 4 can be activated, so that the water in the water tank 2 enters the water outlet pipe 6 through the water suction pipe 5 and the water pump 4. The water in the water outlet pipe 6 will be sprayed out from the two rows of nozzles 7, and the sprayed water will spray on the inner surface of the sorting frame 1 and the surface of the fish, which can increase the lubrication between the fish and the sorting frame 1, promote the fish to slide down the sorting frame 1, and further reduce the damage caused by friction between the fish and the sorting frame 1. At the same time, the water continuously sprayed from the two sets of nozzles 7 can keep the fish in contact with water during sorting, keeping the mucus layer (the fish's natural protective barrier) on its body surface from drying out and breaking, avoiding the invasion of bacteria, and improving the survival rate of the fish during sorting.

[0035] When using water pump 4, it needs to be connected to a suitable external power supply in conjunction with its dedicated controller, and its operation is controlled by its controller.

[0036] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
