After passing through the fish outlet 35 and the connecting space within the clip 50, the fry are sent into the fish outlet channel 501 formed by the first waterway base 51. There are three clips 50, which correspond to the size of the fish outlet 35 in the fish diversion assembly 3. The height of the clip 50 is set to the average height of the fry to further promote the diversion of the fish. There are three waterway outlets 55 in the fry screening device and they are connected to the water tank 54. The water tank 54 is divided into three independent water tanks 54 for receiving the separated fish. The number of independent water tanks divided into the water tank 54 corresponds to the number of waterway outlets 55 and the number is not fixed. The number of fences 53 in the fry screening assembly 5 corresponds to the number of waterway outlets and the number is not fixed.

[0074] like Figure 1As shown, the fish inlet pipe 11 of the fish inlet assembly 1 is connected to the fish inlet 32 ​​of the fish diversion assembly 3; the water diversion pipe 22 of the water inlet diversion assembly 2 is connected to the water inlet 33 of the fish diversion assembly 3; the fish diversion blade 31 of the fish diversion assembly 3 is connected to the drive rod 34 and placed in the fish diversion chamber 301; the fish outlet 35 of the fish diversion assembly 3 is connected to the first channel base 51 of the fry screening assembly 5 via a snap 50; the fence 53 of the fry screening assembly 5 is placed on the inlet side of the channel outlet 55 of the first channel base 51 and is parallel to it; the glass cover 52 is placed on the first channel base 51, and the camera bracket 41 of the fry identification assembly 4 is placed parallel to the first channel base 51 for identifying the type and quality of the fry; and the water tank 54 is connected to the channel outlet 55. By pouring fish into the fish inlet assembly 1, with the cooperation of the water inlet diversion assembly 2, After passing through the fish diversion component 3, the density of the fish school decreases and then passes through the fry screening component 5. The camera 40 of the fry recognition component 4 captures the fry image and combines it with the artificial intelligence algorithm for screening. Then, the camera control device 42 controls the external motor to drive the fence 53 based on the screening results to control the screened fry to enter the water tank 54.

[0075] When assembling the automatic category subdivision device provided in this application, the following steps are included:

[0076] Step 1: Connect the fish inlet pipe 11 of the fish inlet assembly 1 to the fish inlet 32 ​​of the fish diversion assembly 3. Connect the water diversion pipe 22 of the water inlet diversion assembly 2 to the water inlet 33 of the fish diversion assembly 3.

[0077] Step 2: Connect the fish separating blades 31 of the fish diverting assembly 3 to the driving rod 34 and place them into the fish separating chamber 301 .

[0078] Step three: Connect the fish outlet 35 of the fish diversion component 3 to the first waterway base 51 of the fry screening component 5 via the buckle 50 .

[0079] Step 4: Place the fence 53 of the fry screening assembly 5 parallel to the entrance of the waterway outlet 55, closing the entrance to the screening channel 502. Replace the glass cover 52. Place the camera bracket 41 of the fry identification assembly 4 parallel to the first waterway base 51 to identify the type and quality of the fry. The waterway outlet 55 is connected to the water tank 54.

[0080] When the automatic category classification device provided by the present invention is in operation, fish are collected through a hopper 10 and fed into the fish sorting chamber 301 of the fish diversion assembly 3 via a fish inlet pipe 11. A rotating motor then controls the drive rod 34, which drives the fish sorting blades 31, rapidly diverting the fish. Simultaneously, the water inlet diversion assembly continuously supplies water to keep the fry active. After the fry enter the fry screening assembly 5, the fry identification assembly 4 uses a camera 40 combined with an artificial intelligence algorithm to identify the fry's category and quality. Based on the results, the motor-controlled fence 53 then screens and separates the fry, which are then fed into a water tank 54.

[0081] The present invention uses a funnel 10 to quickly collect fish. The fish are then quickly diverted by rotating the fish-dividing blades 31 in combination with the fish-dividing compartment 301. The fish are kept active by continuously injecting water, and then enter the fry screening component 5 for screening and standardization through the camera 40. The screened fry are then sent to the corresponding water tank 54 by controlling the rotation of the fence 53. This solves the problems of low efficiency in the existing manual selection of fry, high cost in fry screening, and inconsistent standards for fry screening. The fish diversion component 3 provided by the present invention greatly improves the efficiency of fish diversion. In terms of category segmentation, a camera 40 is added to unify the screening standards and improve screening efficiency. This reduces labor costs. The present invention solves the problems of low efficiency in the existing manual screening of fry, high cost in fry screening, and inconsistent standards for fry screening.

[0082] Ornamental fish farming has become a new avenue for expanding my country's aquaculture sector and boosting farmers' income and employment. Koi carp farming accounts for a significant portion of ornamental fish farming both domestically and internationally. The ornamental value and economic value of koi carp depend on their color and pattern. The market price of high-quality, premium koi carp can differ by tens or even hundreds of times from that of ordinary koi carp, and prices for different varieties of high-quality koi carp also vary. The biggest challenge facing koi farming is the extremely low yield rate, typically less than 1%. To ensure a sufficient supply of high-quality koi carp while controlling costs and ensuring quality, farms release large quantities of fry. Once the fry reach a certain size, they undergo repeated screening to select the best-quality fry for intensive rearing. Currently, koi fry screening is entirely manual and relies on individual experience, with limited efficiency and standards.

[0083] The automatic fish fry classification device provided by the present invention can be used to automatically classify koi fry, thereby screening out good quality koi fry, which are then sold after intensive breeding, thereby improving economy, screening efficiency and screening effect.
