Description

Technical Field

[0001] This utility model relates to the field of aquatic equipment technology, specifically to an aquatic seedling sorter. Background Technology

[0002] In the field of aquaculture, sorting seedlings by size is a key step in improving breeding efficiency and survival rate; Traditional sorting mainly relies on manual sieve sorting or simple sorting boxes. Manual operation is time-consuming and labor-intensive, making it difficult to meet the needs of large-scale production. In addition, multiple transfers of seedlings can easily cause physical damage and reduce the survival rate. At the same time, sorting tools with fixed mesh cannot flexibly adapt to different sizes of seedlings, requiring repeated equipment replacements and making it difficult to achieve multi-level synchronous sorting.

The lead screw module is fixedly installed on the upper end of the upright. The top end of the connecting rod is connected to the driving end of the lead screw module. The upper side of the sorting frame is connected to the bottom end of the connecting rod. The two pull slots are respectively opened on the lower end of the two side walls inside the sorting frame. The two ends of the secondary sorting mesh frame are respectively movably embedded in the two pull slots. The crossbar is fixedly installed on the upper end of the center inside the sorting frame. The connecting plate is placed on the upper end of the crossbar. The two primary sorting components are symmetrically distributed in the sorting frame relative to the connecting plate.

[0004] Preferably, both of the primary sorting components include: a mounting frame, a movable plate, a fixed plate, a hinge, a positioning plate, a positioning bracket, and positioning bolts; One end of the mounting frame is connected to the side wall of the connecting plate.

The fixed plate is fixedly installed on the other side of the lower end of the mounting frame. The hinge is installed on one side of the upper end of the mounting frame. One end of the positioning plate is hinged to the upper end of the hinge. The lower end of the positioning frame is fixedly installed on one side of the upper wall of the movable plate. The upper end of the positioning frame has a U-shaped groove. The positioning bolt movably passes through one side arm of the U-shaped groove at the upper end of the positioning frame.

[0015] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Example: Please refer to Figure 1-4 A sorting device for aquatic seedlings includes a base plate 1 and a sorting box 2. The sorting box 2 is fixedly installed on the upper end of the base plate 1, and a lifting sorting structure is installed at the rear end of the sorting box 2. The lifting and sorting structure includes: upright pole 3, lead screw module 4, connecting rod 5, sorting frame 6, two pull slots 7, secondary sorting mesh frame 8, crossbar 9, connecting plate 10, and two primary sorting components. The upright pole 3 is fixedly installed on one side of the upper end of the base plate 1 and located on the rear wall of the sorting box 2. The lead screw module 4 is fixedly installed on the upper end of the upright pole 3. The top end of the connecting rod 5 is connected to the driving end of the lead screw module 4. The upper side of the sorting frame 6 is connected to the bottom end of the connecting rod 5. The two pull slots 7 are respectively opened on the lower end of the two side walls inside the sorting frame 6. The two ends of the secondary sorting mesh frame 8 are respectively movably embedded in the two pull slots 7. The crossbar 9 is fixedly installed on the upper end of the center inside the sorting frame 6. The connecting plate 10 is placed on the upper end of the crossbar 9. The two primary sorting components are symmetrically distributed in the sorting frame 6 relative to the connecting plate 10.

[0017] When sorting aquatic seedlings, the staff first moves the device to the designated position and supports it with the base plate 1. Then, according to the size of the seedlings and the sorting requirements, two primary sorting components are placed on the upper end of the crossbar 9 and installed through the connecting plate 10. The side walls of the two primary sorting components are attached to the inner wall of the sorting frame 6 to ensure the stability of the installation. The wall-side primary sorting components are tilted, and then the two primary sorting components are adjusted. Finally, the secondary sorting mesh frame 8 of the specified size is embedded into the sorting frame 6 and connected through two pull slots. 7. Install the secondary sorting frame 8. After installation, the screw module 4 at the upper end of the drive pole 3 works. Under the connection of the connecting rod 5, the sorting frame 6 is embedded into the sorting box 2 and maintains a certain gap with the secondary sorting frame 8. Then, the staff pours the seedlings to be sorted into the sorting box 2. The seedlings are initially sorted by two primary sorting components. Seedlings smaller than the primary sorting components fall into the secondary sorting frame 8. The secondary sorting frame 8 performs secondary sorting. Seedlings smaller than the secondary sorting frame 8 fall into the sorting box 2, realizing multi-level sorting of seedlings.

[0018] In the specific implementation process, both primary sorting components include: mounting frame 11, movable plate 12, fixed plate 13, hinge seat 14, positioning plate 15, positioning bracket 16, and positioning bolt 17. One end of the mounting frame 11 is connected to the side wall of the connecting plate 10. The top of the movable plate 12 is movably connected to one side of the lower end of the mounting frame 11 via a shaft. The fixed plate 13 is fixedly installed on the other side of the lower end of the mounting frame 11. The hinge seat 14 is installed on one side of the upper end of the mounting frame 11. One end of the positioning plate 15 is hinged to the upper end of the hinge seat 14. The lower end of the positioning frame 16 is fixedly installed on one side of the upper wall of the movable plate 12. The upper end of the positioning frame 16 has a U-shaped groove. The positioning bolt 17 movably passes through one side arm of the U-shaped groove at the upper end of the positioning frame 16. The other end of the positioning plate 15 movably passes through the opening of the U-shaped groove at the upper end of the positioning frame 16.

[0019] When sorting seedlings of different sizes, the staff adjusts the angle of the movable plate 12 at the lower end of the mounting frame 11 according to the sorting requirements. Then, one end of the positioning plate 15 in the hinge seat 14 is inserted into the U-shaped groove of the positioning frame 16. By turning the positioning bolt 17, one end of the positioning bolt 17 contacts the side wall of the positioning plate 15, and the position of the positioning plate 15 is pressed and fixed. This achieves the purpose of fixing the angle of the movable plate 12, so that the bottom end of the movable plate 12 and the bottom end of the fixed plate 13 form a gap with a specified spacing, and the seedlings are sorted through the gap.

[0020] In the specific implementation process, the front end of the sorting box 2 is provided with a retrieval operation hole 18, which facilitates quick seedling retrieval, reduces the seedling exposure time, and retrieves the seedlings that have completed the secondary screening by the secondary sorting frame 8.

[0021] In the specific implementation process, a sorting mesh 19 is installed on the lower wall of the secondary sorting mesh frame 8 to adapt to diverse sorting needs.

[0022] In the specific implementation process, both the fixed plate 13 and the movable plate 12 are installed at an angle at the lower end of the installation frame 11 to optimize the sliding path of the seedlings and avoid blockage.

[0023] In the specific implementation process, one end of the positioning bolt 17 contacts the side wall of the positioning plate 15 to achieve stepless adjustment of the sorting gap and accurately adapt to seedlings of different sizes.
