[0002] Accurate and rapid counting of fry is an important guarantee for the smooth operation of the fry sales, circulation, and stocking links. Currently, fry counting in breeding farms still mostly relies on manual counting methods, where fish are manually fished, counted, and packed. This method has defects such as high labor costs and low work efficiency. Moreover, during the counting process, fry are stressed due to multiple artificial operations such as fishing and loading, which easily cause physical damage and physiological stress reactions, affecting the survival rate during subsequent transportation or early-stage breeding. Summary of the Invention:

Specific Embodiments:

[0034] The following further describes the present invention with specific embodiments, referring to Figure 1 —6:

[0035] One of the objectives of the present invention is to provide a precise fry counting and sorting device, which is used to quantitatively sort fry and then pack them to improve the packing efficiency and reduce the labor cost. The precise fry counting and sorting device includes: a fish pond assembly, a sorting channel assembly, a deflector 1, a counting sensor, and a control system. Specifically, the fish pond assembly includes a fish pond 2 and a lifting net 3 that is liftably arranged in the fish pond 2. The lifting net 3 is driven by a driving mechanism to move up and down, and is used to lift the fry to the sorting position; the sorting channel assembly includes at least one sorting channel 4, and each sorting channel 4 has two or more gate plates 5 arranged at intervals along the length direction of the sorting channel 4. Each gate plate 5 is controlled by an independent driving member 6 and is used to segmentally block or open the sorting channel; the driving member 6 can be a motor, a cylinder, or the like. A first outlet hole 7 is provided at the upper end of the fish pond 2, and the deflector 1 passes through the first outlet hole 7. One end of the deflector 1 is located in the fish pond 2, and the other end is connected to the inlet of the sorting channel 4, and is used to guide the fry to enter the sorting channel 4 from the fish pond 2; the counting sensor is arranged on the sorting channel 4 between the gate plates 5 and is used to monitor the number of fry passing through in real time; the counting sensor is signal-connected to the driving member 6. When the counting sensor detects that the number of fry reaches the set value, it controls the downstream gate plate 5 to close to achieve quantitative interception. It should be noted that the counting sensor can adopt a photoelectric counting sensor, a proximity switch, a mechanical counter, or the like.

[0036] As can be seen from the above, the present invention automatically quantitatively sorts fry, realizes continuous and rapid sorting of fry, and ensures that the number of fry in each package is consistent. Compared with manual counting and sorting, the efficiency is increased by 5-10 times, greatly improving the work efficiency and reducing the labor cost. The design of multiple sorting channels 4 can process fry in parallel and has the ability to process batches, further shortening the overall packing time. In addition, mechanical sorting replaces manual fishing, reducing stress or physical damage caused by contact of fry.

[0037] In order to improve the stability and reliability of the lifting of the lifting net 3, the present invention is provided with a mounting plate 8 at the upper end of the fish pond 2, and guide rods 9 are respectively arranged at both ends of the mounting plate 8. The guide rods 9 penetrate through the lifting net 3. In this embodiment, the mounting plate 8 is provided with guide rod holes, the lower ends of the guide rods pass through the guide rod holes and the lifting net 3, and the upper ends are locked and fixed to the mounting plate 8 by nuts.

[0038] Furthermore, the driving mechanism of the present invention is arranged on the mounting plate 8, and the driving mechanism can adopt any one of a worm and gear structure, a hydraulic cylinder, a cylinder, and an electric push rod. In this embodiment, a worm and gear structure is adopted. Specifically, a motor 10, a worm, and a worm gear 11 are fixedly arranged on the mounting plate 8, and the worm 11 penetrates through the mounting plate 8 and extends into the fish pond 2 to be fixedly connected to the lifting net 3.

[0039] In addition, each sorting channel 4 of the present invention is distributed in a serpentine and circuitous manner, significantly extending the effective sorting length, improving the counting accuracy, and at the same time reducing the floor area and making the structure more compact. Moreover, the serpentine and circuitous distribution makes the sorting channel 4 have turning points, and the micro-turbulence generated at the turning points automatically disperses the fry, avoiding the problem of fry bunching that is likely to occur in a straight channel and leading to missed counting during inspection.

[0040] In order to keep the water level line in the fish pond 2 at a certain height, the present invention further defines the structure of the fish pond 2 as follows: The fish pond 2 includes an upper box body 12 and a lower box body 13, and the upper box body 12 and the lower box body 13 are separated by a partition plate 14, and the partition plate 14 is fixed by welding or other means.

The nuts are respectively located at the upper and lower ends of the partition plate 14. Correspondingly, an avoidance hole for avoiding the overflow pipe 15 is arranged on the lifting net 3.

[0041] In addition, the present invention is also equipped with a closed-loop water circulation system. The sorting channel 4 is arranged in the upper part of the water tank 16.

A water pump is arranged in the water tank 16, and a spray head connected to the water pump is arranged on the outer side wall of the fish pond 2 corresponding to the first outlet hole 7 to circulate the water into the upper box body 12 or / and the sorting channel 4, which can reduce the need for water change. The directional water flow of the spray head can assist the fry to enter the sorting channel 4 from the fish pond 2 and prevent the fry from gathering and blocking.

[0042] The present invention is provided with second outlet holes on the water tank 16 that correspond one-to-one in number and position to the sorting channels 4. The outlets of the sorting channels 4 pass through the second outlet holes and extend outside the water tank 16. A water-containing box is equipped at the outlet of each sorting channel 4, and the box is arranged on a conveyor for automatic conveying.

[0043] In order to prevent the fry from escaping, fry anti-escape structures are arranged on the side wall of the fish pond 2 above each first outlet hole 7 and on the outer side wall of the water tank 16 above the second outlet holes.

[0046] S1. The control system periodically controls the driving mechanism to act, controls the lifting net 3 to rise, and lifts the fry from the fish pond 2 to the sorting position;

[0047] S2. The fry enter the sorting channel 4 through the guide plate 1, and the counting sensor continuously monitors the number of fry flowing through the area between the gate plates 5;

[0048] S3. When the counting sensor detects that the number of fry reaches the set value, the control system controls the downstream gate plate 5 to close to achieve quantitative interception;

[0049] S4. Repeat steps S2 - S3 until the quantitative sorting of all fry is completed.

[0050] It should be noted that the fry of the present invention are pumped into the fish pond 2 through a water pump or the like.

[0051] The above embodiments are only one of the preferred embodiments of the present invention, and do not limit the scope of implementation of the present invention.
