Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, and more specifically, to an automated fine sorting and counting device for aquaculture fry. Background Technology

[0002] Fish breeding, rearing, and stocking. Fish farming, also known as aquaculture, fish farming, and fish industry, is important for maintaining food supplies, angling, and expanding fishing areas. Through fish farming, many species have been successfully introduced into new areas. During the rearing process, due to the varying sizes of fish fry, it is necessary to separate them into different ponds to avoid interference between fry of different sizes. This process requires distinguishing and counting the fry to prevent larger fry from affecting the survival rate of smaller fry.

[0003] According to the search, patent CN111657206B discloses a fish fry sorting and counting device for aquaculture, including: a water tank; an inlet pipe connected to one side of the water tank; a water pump fixed to one side of the water tank; a water delivery pipe connected to one side of the water pump; fish boxes symmetrically arranged on one side of the water tank, with the water delivery pipe connected to each of the two fish boxes; a support frame fixed to one side of the water tank; and a drive mechanism mounted on the support frame, which drives a gear to rotate via a motor. Through the meshing of the gear and rack, the rack moves, thereby driving the guide tube, guide column, and the fishing mechanism below to move horizontally, allowing the fishing mechanism to be adjusted in position between the two fish boxes according to work needs. By setting different sized holes in the upper and lower parts of the fishing cage, when the fishing cage is immersed in the left fish box, fish fry can enter the fishing cage through the larger holes, while when the fishing cage is lifted, only small fish fry can flow back into the fish box through the smaller holes at the lower part of the fishing cage, completing one sorting of the fish fry.

[0004] Regarding the aforementioned technologies, current existing technologies for distinguishing between large and small fish fry typically employ methods similar to those described above, or manual sorting. Due to the large number of fry in each pond, manual sorting has low automation, resulting in low overall sorting efficiency and accuracy. While the aforementioned fry sorting and counting devices can distinguish between large and small fry, in reality, the counting method is not intuitive, the count is difficult to view, and it cannot finely group fry according to size gradients. This leads to mixed rearing of fry of different sizes, making overall management difficult due to size differences. It also hinders precise monitoring of the health status of each size group, making it impossible to take more effective preventative and treatment measures for specific size groups when problems are detected. This affects precise feeding and health management, reducing fry survival rates and hindering the development of smart fisheries. Therefore, an automated fine sorting and counting device for aquaculture fry is proposed. Summary of the Invention

[0039] The following is in conjunction with the appendix Figures 1-11 The present invention will be described in further detail below.

[0040] Please see Figures 1-11An automated fine sorting and counting device for aquaculture fish fry includes a main module 100, a conveying module 200, and multiple counting modules 300. The main module 100 includes a main frame 110, a fry sorting component 120, and an inlet component 130. The inlet component 130 is connected between the main frame 110 and the fry sorting component 120. Multiple sorting boxes 140 are arranged in a straight line at equal intervals on the bottom of the inner wall of the main frame 110. The conveying module 200 includes two bottom plates 210 that are respectively fixedly connected to both sides of the inner wall of the main frame 110. The adjacent sides of the two bottom plates 210 are provided with inclined grooves. The top of the bottom plates 210... An auxiliary transport component 220 is provided between the plate and one side of the inner wall of the main frame 110. Multiple counting modules 300 are all located at the bottom of the inner wall of the main module 100. The multiple counting modules 300 are arranged in a straight line at equal distances. A reset module 400 is provided between the multiple counting modules 300. Each counting module 300 includes a toggle component 310 located between the two sides of the inner wall of the main frame 110. The toggle component 310 is located above one of the sorting boxes 140. A transmission component 320 adapted to the toggle component 310 is provided on one side of the main frame 110. A digital roller 330 is fixedly connected inside the transmission component 320.

[0041] In use, the larger fry are scooped up by the seedling sorting component 120 and then enter the guide component 130. The fry then gradually move towards the auxiliary transport component 220, which opens to assist the fry in moving between two inclined troughs. When the fry are no longer supported by the two base plates 210, they fall into the corresponding sorting box 140 below, thus achieving more refined sorting. Upon falling, the fry pass through the actuating component 310, which in turn drives the transmission component 320, causing the digital roller 330 to rotate and change the displayed numbers. The auxiliary transport component 220 operates continuously to continuously sort the fry. Each digital roller 330 displays the number of fry of a corresponding volume. The total number of fry is then determined by adding the numbers displayed by multiple digital rollers 330.

[0042] The auxiliary transport assembly 220 includes a mounting plate 221 fixedly connected to one side of the inner wall of the main frame 110. Two auxiliary rollers 222 are rotatably connected to the top of each of the two base plates 210. A transmission belt 223 is driven between the outer surfaces of each pair of auxiliary rollers 222. A sponge sleeve 224 is fixedly connected to the outer surface of each of the two transmission belts 223. Two drive motors 225 are fixedly connected to the top of the mounting plate 221. The output shafts of the two drive motors 225 are respectively connected to the top ends of two of the auxiliary rollers 222. The actuation assembly 310 includes components rotatably connected between the two sides of the inner wall of the main frame 110. The rotating shaft 311 has one end extending to the outside of the main frame 110 and fixedly connected to an incomplete bevel tooth 313. A flip plate 312 is fixedly connected to the outer surface of the rotating shaft 311, and the flip plate 312 is located above one of the sorting boxes 140. A first torsion spring 314 is fixedly connected between the outer surface of the rotating shaft 311 and one side of the main frame 110. The transmission assembly 320 includes a viewing box fixedly connected to one side of the main frame 110. An inner rotating shaft 321 is rotatably connected between the two sides of the inner wall of the viewing box, and both ends of the inner rotating shaft 321 extend to the outside of the viewing box. A second torsion spring 322 is fixedly connected between one end of the inner rotating shaft 321 and the outer surface of the viewing box. An inner wheel 323 is fixedly connected to the other end of the inner rotating shaft 321. An annular bevel gear 324 is rotatably connected to the outer surface of the inner wheel 323. An annular ratchet groove 325 is formed on the inner wall of the annular bevel gear 324. A plurality of first ratchet racks 326 are movably connected to the outer surface of the inner wheel 323. A first movable spring 327 is fixedly connected between one end of each of the plurality of first ratchet racks 326 and the inner wall of the inner wheel 323. The other ends of each of the plurality of first ratchet racks 326 are movably connected inside the annular ratchet groove 325. The tooth 324 is adapted to the incomplete bevel tooth 313. The transmission assembly 320 also includes a ratchet 3210 fixedly connected to the outer surface of the inner rotating shaft 321. A sleeve 328 is fixedly connected to the bottom of the inner wall of the viewing box. A second ratchet rack 329 is movably connected inside the sleeve 328. The top end of the second ratchet rack 329 is movably connected to the outer surface of the ratchet 3210. A second movable spring 3211 is fixedly connected between the bottom end of the second ratchet rack 329 and the bottom of the inner wall of the sleeve 328. A pull rod 3212 is fixedly connected to the bottom end of the second ratchet rack 329. The bottom end of the pull rod 3212 extends to the bottom of the viewing box.

[0043] Upon falling, the fish fry will pass over the flip plate 312, which drives the rotating shaft 311 to rotate. The rotation of the rotating shaft 311 will drive the incomplete bevel gear 313 to rotate, which in turn drives the annular bevel gear 324. The annular bevel gear 324 will push the first ratchet rack 326 through the annular ratchet groove 325. The first ratchet rack 326 will drive the inner wheel 323 to rotate, which in turn drives the inner rotating shaft 321 to rotate. At this time, the digital roller 330 and the ratchet 3210 rotate. The rotation of the ratchet 3210 will drive the second ratchet rack 329 to move, thus engaging the second torsion spring 322. Meanwhile, the digital roller 330 rotates... When the digital display is switched, the first torsion spring 314 will drive the incomplete bevel gear 313 to rotate and reset. The second ratchet rack 329 and ratchet wheel 3210 restrict the rotation direction of the inner rotating shaft 321, so that the incomplete bevel gear 313 will drive the annular bevel gear 324 to rotate. The annular groove 325 will drive the first ratchet rack 326 to retract and the annular bevel gear 324 to idle. The auxiliary transport component 220 runs continuously to continuously sort the fish fry. Each digital roller 330 will display the number of fish fry of the corresponding volume. The total number of fish fry can be known by adding the numbers displayed by multiple digital rollers 330.

[0044] The reset module 400 includes two hollow blocks 410. Floating rods 420 are movably connected inside each of the two hollow blocks 410. A third movable spring 430 is fixedly connected between the top of each of the two floating rods 420 and the inner wall of each of the two hollow blocks 410. A connecting rod 440 is fixedly connected between the bottom ends of the two floating rods 420. A pull plate 450 is fixedly connected to the bottom of the connecting rod 440. Both hollow blocks 410 are connected to the viewing box. The connecting rod 440 is located inside the bottom end of the pull rod 3212.

[0045] Pulling down the pull plate 450 will cause the connecting rod 440 to descend. The descent of the connecting rod 440 will pull the third movable spring 430 through the floating rod 420. At this time, the connecting rod 440 pulls the pull rod 3212, which will cause the second ratchet 329 to descend and separate from the ratchet 3210. At this time, the second torsion spring 322 will drive the inner rotating shaft 321 to reset, thereby resetting the multiple digital rollers 330, making the reset of the digital rollers 330 more convenient and uniform.

[0046] The inlet component 130 includes a fish bucket 131 fixedly connected to the seedling sorting component 120. The fish bucket 131 is inclined. One end of the fish bucket 131 is fixedly connected to an inlet channel 132. One end of the inlet channel 132 is located between the ends of two sponge sleeves 224. A water guide pipe 133 is fixedly connected between the two sides of the inner wall of the fish bucket 131. A water pump 134 is installed on the seedling sorting component 120. The output end of the water pump 134 is connected to one end of the water guide pipe 133.

[0047] Turn on the water pump 134 to pump water into the water pipe 133, and fill the fish tank 131 with water through the water pipe 133, so that the fish fry can swim more easily and avoid being in a horizontal position.

[0048] The seedling sorting component 120 includes a seedling box, a fish bucket 131 fixedly connected to the rear end of the seedling box, a water pump 134 fixedly connected to the outer surface of the seedling box, cylinders 125 fixedly connected to both sides of the seedling box, and steering rods 126 fixedly connected to the output shafts of the two cylinders 125. One end of each steering rod 126 extends into the interior of the seedling box, and a large-aperture filter 121 is fixedly connected between the ends of the two steering rods 126. The large-aperture filter 121 is inclined. The seedling sorting component 120 also includes two triangular plates 122 fixedly connected to the bottom of the large-aperture filter 121. Each adjacent side of the two triangular plates 122 has a strip groove 123. A small-aperture filter 124 is slidably connected between the inner walls of the two strip grooves 123. A disassembly groove is provided on the front end of the seedling box, and the disassembly groove is adapted to the small-aperture filter 124.

[0049] Open cylinder 125. Cylinder 125 lifts the large-pore filter 121 and the small-pore filter 124 via steering rod 126, so that the larger fish fry are above the large-pore filter 121 and the smaller fish fry are above the small-pore filter 124. The small-pore filter 124 is removed and weighed through the disassembly slot. Finally, the weight of the small-pore filter 124 itself is subtracted to get the weight of the small fish fry. The total weight of the small fish fry divided by the weight of a single small fish fry can estimate the total number of small fish fry. Since the large-pore filter 121 is set at an angle, the large fish fry enter the fish bowl 131.

[0050] The main module 100 also includes multiple water level tanks 150 respectively opened on one side of multiple sorting boxes 140, and the multiple water level tanks 150 are at the same height.

[0051] By setting the water level tank 150, a certain water level is maintained inside the sorting box 140 to prevent the water level from being too high and affecting the flip plate 312 from flipping, thereby improving the counting accuracy.

[0052] The implementation principle of this invention is as follows: During use, the fish fry are inside the brooding box. The cylinder 125 is opened, and the cylinder 125, via the steering rod 126, lifts the large-pore filter 121 and the small-pore filter 124. This allows larger fish fry (over 4 cm in length) to be positioned above the large-pore filter 121, and smaller fish fry (under 4 cm in length) to be positioned above the small-pore filter 124. The small-pore filter 124 is removed and weighed using a disassembly slot. The weight of the small-pore filter 124 itself is then subtracted from the weight of the small-pore filter 124 to obtain the weight of the fish fry. The total weight of the fish fry divided by the weight of a single fish fry gives the estimated number of fish fry. Because the large-pore filter 121 is tilted, the larger fish fry enter the fish tank 131. The water pump 134 is turned on, thus pumping water through the tank. Pump 134 draws water into the water pipe 133, filling the fish tank 131 with water. The water is then discharged through the inlet channel 132, which is designed to allow only one fish fry to pass through at a time. The fry follow the water flow and pass through the inlet channel 132 sequentially, swimming through it. Two drive motors 225 are activated, driving two auxiliary rollers 222, which in turn rotate two drive belts 223, causing two sponge belts 224 to rotate. The fry enter between the two sponge belts 224 and are positioned between two inclined grooves. The sponge belts 224 assist the fry in their movement between the two inclined grooves. When the fry are no longer supported by the two base plates 210, they will... The fry fall into the corresponding sorting box 140 below, thus completing a more refined classification of the fish fry. During the fall, the fry pass over the flipping plate 312, which drives the rotating shaft 311 to rotate. The rotating shaft 311 then drives the incomplete bevel gear 313 to rotate, which in turn drives the annular bevel gear 324. The annular bevel gear 324 then pushes the first ratchet rack 326 through the annular ratchet groove 325. The first ratchet rack 326 drives the inner wheel 323 to rotate, which in turn drives the inner rotating shaft 321 to rotate. At this time, the digital roller 330 and the ratchet 3210 rotate. The ratchet 3210 then drives the second ratchet rack 329 to move, causing the second torsion spring 322 to be engaged. Meanwhile, the digital roller 330... The digital display is switched by rotating the first torsion spring 314, which then drives the incomplete bevel gear 313 to rotate and reset. The second ratchet rack 329 and ratchet wheel 3210 restrict the rotation direction of the inner shaft 321, causing the incomplete bevel gear 313 to push the annular bevel gear 324 to rotate. The annular groove 325 then pushes the first ratchet rack 326 to retract, and the annular bevel gear 324 to idle. The auxiliary transport component 220 operates continuously, thus continuously sorting the fish fry. Each digital roller 330 displays the number of fish fry of a corresponding volume. The total number of fish fry is then determined by adding the numbers displayed by multiple digital rollers 330, completing the counting process. This enables simultaneous and coordinated multi-level fine sorting and automatic counting of fish fry.Fine-grained sorting facilitates precise feeding and health management decisions. After counting is complete, pulling the sorting box 140 to the other side allows for the removal of finely sorted fry. When sorting larger fry, the sorting boxes 140 are arranged sequentially: the first box holds fry of 4-5 cm, the second holds fry of 5-6 cm, the third holds fry of 6-7 cm, and so on. To reset the count on the digital roller 330, the operator can pull down the pull plate 450. The pull plate 450 will lower the connecting rod 440, which in turn will pull the third movable spring 430 via the floating rod 420. At this time, the connecting rod 440 pulls the pull rod 3212, which in turn will activate the second ratchet. The ratchet 329 descends, separating from the ratchet 3210. At this point, the second torsion spring 322 drives the inner rotating shaft 321 to reset, thereby resetting multiple digital rollers 330. This makes the resetting of the digital rollers 330 more convenient and unified. The real-time fish fry size distribution data generated by the digital rollers can be directly uploaded to the intelligent fisheries management system by staff, facilitating fish fry management. Simultaneously, the improved counting efficiency and automated operation mode effectively reduce labor costs and subjective errors, promoting the development of aquaculture towards intelligence and precision. This provides key equipment support for the industrial goals of "precise aquaculture decision-making, efficient resource utilization, and full-process digital management" in intelligent fisheries, accelerating the transformation of traditional aquaculture towards intelligence.
