Description

Technical Field

[0001] This utility model relates to the technical field of aquatic seedling sorting devices, and in particular to an aquatic seedling sorting device. Background Technology

[0002] The main function of aquatic seedling sorters is to effectively classify fry of different sizes based on their size, weight, and morphology through precise screening and separation. This process is crucial for aquaculture because fry of different sizes have varying environmental requirements and growth rates. By using sorters, it is ensured that each type of fry is placed in its most suitable growth environment, thereby improving survival rates and growth speeds. Furthermore, sorters reduce collisions and damage to fry during the sorting process, minimizing stress and ensuring the health and vitality of the fry. Overall, aquatic seedling sorters not only improve work efficiency but also optimize aquaculture management, promoting the economic benefits and sustainable development of aquaculture.

[0003] However, in existing technologies, the components of aquatic seedling sorters are usually fixed by bolts or welding. When the type, size, or quantity of fish fry changes, the fixed screening angle cannot meet the optimal sorting requirements, resulting in a decrease in sorting efficiency and affecting the efficiency of seedling sorting, which is a defect. Utility Model Content

[0004] The purpose of this invention is to address the technical problem that in existing aquatic seedling sorters, the components are usually fixed by bolts or welding. When the type, size, or quantity of fish fry changes, the fixed screening angle cannot meet the optimal sorting requirements, resulting in a decrease in sorting efficiency and affecting the efficiency of seedling sorting. Therefore, this invention proposes an aquatic seedling sorter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an aquatic seedling sorter, comprising a support assembly, a rotating shaft rotatably connected to one side surface of the support assembly via a bearing, a screening plate fixedly connected to one end of the rotating shaft, a plurality of screening holes being formed on the upper surface of the screening plate, a support connecting plate fixedly connected to the upper surface of the support assembly, an adjusting rod threadedly connected to the upper surface of the support connecting plate, a support column rotatably connected to the lower end of the adjusting rod via a bearing, a pull rod rotatably connected to the lower end of the support column, an adjusting block rotatably connected to one end of the pull rod, one end of the adjusting block being fixedly connected to the outer surface of the screening plate, three collection boxes being provided below the screening plate, and a baffle fixedly connected to one side surface of the screening plate.

[0006] Furthermore, the plurality of sieve holes are divided into three groups, and the three groups of sieve holes are distributed at equal intervals.

[0007] Furthermore, the lower surface of the screening plate is rotatably connected to two partitions via hinges, and the two partitions are located above the three collection boxes.

[0008] Furthermore, a knob is fixedly connected to the upper surface of the adjusting rod, and multiple grooves are formed on the outer surface of the knob.

[0009] Furthermore, the plurality of grooves are equidistantly distributed.

[0010] Furthermore, an angle adjustment gauge is fixedly connected to one side surface of the support component.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, during use, rotating the adjusting rod causes the threaded rod to pull one end of the pull rod upward through the bearing and support column, causing the screening plate to rotate through the shaft after being subjected to force. This adjusts the angle between the screening plate and the horizontal plane. Then, the fish fry are transported onto the inclined screening plate by the water flow. Driven by the water flow and gravity, the fish fry pass through multiple screening holes in sequence. The diameter of the multiple screening holes increases linearly, allowing fish fry of different sizes to pass through multiple screening holes in sequence and fall into the collection box. The fish fry are sorted according to their size. The angle between the screening plate and the horizontal plane can be freely adjusted by rotating the adjusting rod. By adjusting the angle of the filter plate, the sliding speed of the fish fry can be controlled. When the angle is steeper, the fish fry slide faster, and when the angle is gentler, the sliding speed of the fish fry is slower, effectively improving the efficiency of fish fry sorting.

[0013] 2. In this utility model, three sets of screening holes are evenly distributed to ensure the separation range of fish fry of different sizes. Two partitions limit the falling range of fish fry during the separation process to prevent the position of fish fry from shifting when falling and to ensure that the fish fry fall into the corresponding collection box. The knob increases the lever arm when rotating the adjustment rod. Multiple grooves are evenly distributed to evenly increase the friction between the fingers and the knob, prevent the fingers from slipping, and improve the user experience. The angle adjustment table allows for intuitive observation of the angle between the screening plate and the horizontal plane, which is convenient for staff to make precise adjustments.

[0019] 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.

[0020] Example 1

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: an aquatic seedling sorter, including a support assembly 1, a rotating shaft 14 rotatably connected to one side surface of the support assembly 1 via a bearing, a screening plate 8 fixedly connected to one end of the rotating shaft 14, a plurality of screening holes 11 opened on the upper surface of the screening plate 8, a support connecting plate 2 fixedly connected to the upper surface of the support assembly 1, an adjusting rod 3 threadedly connected to the upper surface of the support connecting plate 2, a support column 13 rotatably connected to the lower end of the adjusting rod 3 via a bearing, a pull rod 4 rotatably connected to the lower end of the support column 13, an adjusting block 5 rotatably connected to one end of the pull rod 4, one end of the adjusting block 5 fixedly connected to the outer surface of the screening plate 8, three collection boxes 12 provided below the screening plate 8, and a baffle 9 fixedly connected to one side surface of the screening plate 8.

[0022] In this embodiment, during use, rotating the adjusting rod 3 causes the threaded rod 3 to pull one end of the pull rod 4 upward through the bearing and support column 13, causing the screening plate 8 to rotate through the rotating shaft 14 after being subjected to force. This adjusts the angle between the screening plate 8 and the horizontal plane. Then, the fish fry are transported onto the inclined screening plate 8 by the water flow. Driven by the water flow and gravity, the fish fry pass through multiple screening holes 11 in sequence. The diameter of the multiple screening holes 11 increases linearly, allowing fish fry of different sizes to pass through the multiple screening holes 11 in sequence and fall into the collection box 12. The fish fry are sorted according to their size. The angle between the screening plate 8 and the horizontal plane can be freely adjusted by rotating the adjusting rod 3. By adjusting the angle of the filter plate, the sliding speed of the fish fry can be controlled. When the angle is steeper, the fish fry slide faster, and when the angle is gentler, the sliding speed of the fish fry is slower, effectively improving the efficiency of fish fry sorting.

[0023] Example 2

[0024] like Figure 1-4 As shown, multiple screening holes 11 are divided into three groups, and the three groups of screening holes 11 are equidistantly distributed. The lower surface of the screening plate 8 is connected to two partitions 10 by hinges. The two partitions 10 are located above the three collection boxes 12. A knob 6 is fixedly connected to the upper surface of the adjusting rod 3. Multiple grooves 7 are opened on the outer surface of the knob 6, and the multiple grooves 7 are equidistantly distributed. An angle adjustment gauge 15 is fixedly connected to one side surface of the support assembly 1.

[0025] In this embodiment, three sets of sieve holes 11 are equidistantly distributed to ensure the separation range of fish fry of different sizes. Two partitions 10 limit the falling range of fish fry during the separation process to prevent the position of the fish fry from shifting when falling and to ensure that the fish fry fall into the corresponding collection box 12. The knob 6 increases the lever arm when rotating the adjustment rod 3. Multiple grooves 7 are evenly distributed to evenly increase the friction between the fingers and the knob 6, prevent the fingers from slipping, and improve the user experience. The angle adjustment table 15 allows for intuitive observation of the angle between the sieve plate 8 and the horizontal plane, which is convenient for staff to make precise adjustments.

[0026] Working principle: such as Figure 1-4 As shown, during use, rotating the adjusting rod 3 causes the threaded rod 3 to pull one end of the pull rod 4 upwards via the bearing and support column 13, causing the screening plate 8 to rotate via the rotating shaft 14 after being subjected to force. This adjusts the angle between the screening plate 8 and the horizontal plane. Then, the fish fry are transported onto the inclined screening plate 8 by the water flow. Driven by the water flow and gravity, the fish fry pass through multiple screening holes 11 in sequence. The diameter of the multiple screening holes 11 increases linearly, allowing fish fry of different sizes to pass through the multiple screening holes 11 in sequence and fall into the collection box 1. Inside 2, the fish fry are sorted according to their size. Three sets of sieve holes 11 are evenly distributed to ensure the separation range of fish fry of different sizes. Two partitions 10 limit the falling range of the fish fry during the separation process to prevent the fish fry from shifting their position when falling and to ensure that the fish fry fall into the corresponding collection box 12. The knob 6 increases the lever arm when rotating the adjustment rod 3. Multiple grooves 7 are evenly distributed to evenly increase the friction between the fingers and the knob 6 to prevent the fingers from slipping. The angle adjustment table 15 allows for a direct observation of the angle between the sieve plate 8 and the horizontal plane.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
