Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and more particularly to an automatic fine sorting and counting device for fish fry used in aquaculture. Background Art

[0002] The breeding, rearing, and stocking of fish. Fish farming, also known as aquaculture, fish farming, and fish farming, 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 fry, the fry must be separated into separate ponds to prevent them from interfering with each other. During this process, the fry must be separated and counted to prevent larger fry from affecting the survival rate of smaller fry.

[0003] According to a search, patent number CN111657206B discloses a fry sorting and counting device for aquaculture, comprising: a water tank; a water inlet pipe connected to one side of the water tank; a water pump fixedly connected to one side of the water tank; a water supply pipe connected to one side of the water pump; fish boxes symmetrically arranged on one side of the water tank, the water supply pipe being connected to two fish boxes respectively; a bracket first fixedly connected to one side of the water tank; a drive mechanism disposed on the bracket first, wherein a motor drives a gear to rotate, and the meshing action of the gear rack drives the rack to move, thereby driving the guide tube, the guide column and the fishing mechanism below to move horizontally, so that the fishing mechanism can be adjusted between the two fish boxes according to working needs; by providing holes of different sizes on the upper and lower parts of the scoop cage first, when the scoop cage first is immersed in the left fish box, the fry can enter the scoop cage first through the large hole, and when the scoop cage first is lifted, only the small fry can flow back into the fish box through the small hole in the lower part of the scoop cage, completing the first sorting of the fry.

[0004] With regard to the above-mentioned related technologies, at present, the existing technology for distinguishing between large and small fry is usually similar to the above-mentioned method, or is screened and distinguished by manual methods. Since there are a large number of fry when dividing the ponds, the manual method has a low degree of automation, so the overall sorting efficiency is low, and the sorting accuracy is not high. Although the above-mentioned fry sorting and counting device can achieve the distinction between large and small fish fry, in reality, the counting method is not intuitive enough, the number of counting processes is not convenient to view, and it is impossible to finely group them according to the body size gradient, resulting in mixed breeding of fry of different sizes. The difference in body size will make it difficult to manage the whole, and it is not convenient to monitor the health status of each size group more accurately. When problems are found, it is impossible to take more effective preventive and treatment measures for the size group, which affects the precise feeding and health management, reduces the survival rate of fry, and is not conducive to the development of smart fisheries.

The teeth 324 are adapted to the incomplete bevel teeth 313, and the transmission assembly 320 also includes a ratchet 3210 fixedly connected to the outer surface of the inner rotating shaft 321. The bottom of the inner wall of the viewing box is fixedly connected with a sleeve 328, and the interior of the sleeve 328 is movably connected with a second ratchet bar 329. The top of the second ratchet bar 329 is movably connected to the outer surface of the ratchet 3210, and a second movable spring 3211 is fixedly connected between the bottom end of the second ratchet bar 329 and the bottom of the inner wall of the sleeve 328.

[0043] When the fry falls, it will pass through the flip plate 312, which will drive the rotating shaft 311 to rotate. When the rotating shaft 311 rotates, it will drive the incomplete bevel gear 313 to rotate. The incomplete bevel gear 313 drives the annular bevel gear 324. The annular bevel gear 324 will push the first ratchet bar 326 through the annular ratchet groove 325. The first ratchet bar 326 will drive the inner wheel 323 to rotate.

Subsequently, the numbers displayed by multiple digital rollers 330 can be added together to know the total number of fry, thus completing the counting.

[0044] The reset module 400 includes two hollow blocks 410, and the interior of the two hollow blocks 410 is movably connected with a floating rod 420. A third movable spring 430 is fixedly connected between the top of the two floating rods 420 and the inner wall of the two hollow blocks 410.

The two hollow blocks 410 are both connected to the visual box, and the connecting rod 440 is located inside the bottom end of the pull rod 3212.

[0045] Pull the pull plate 450 downward, the pull plate 450 will drive the connecting rod 440 to descend, and 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, and the pull rod 3212 will drive the second ratchet bar 329 to descend and separate from the ratchet wheel 3210. At this time, the second torsion spring 322 will drive the inner rotating shaft 321 to reset, thereby resetting multiple digital rollers 330, making the reset of the digital rollers 330 more convenient and unified.

[0046] The introduction component 130 includes a fish bucket 131 fixedly connected to the seedling sorting component 120. The fish bucket 131 is arranged at an angle. One end of the fish bucket 131 is fixedly connected to an introduction channel 132. One end of the introduction channel 132 is located between one end of the two sponge belts 224. A water 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, and the output end of the water pump 134 is connected to one end of the water pipe 133.

[0047] The water pump 134 is turned on to pump water into the water pipe 133 through the water pump 134, and the inside of the fish bucket 131 is filled with water through the water pipe 133, thereby facilitating the swimming of the fry and preventing the fry from being in a horizontal state.

[0048] The seedling sorting assembly 120 includes a seedling box, a fish bucket 131 is fixedly connected to the rear end face of the seedling box, a water pump 134 is fixedly connected to the outer surface of the seedling box, and cylinders 125 are fixedly connected on both sides of the seedling box. The output shafts of the two cylinders 125 are fixedly connected to steering rods 126, and one end of the two steering rods 126 extends to the interior of the seedling box.

The seedling sorting assembly 120 also includes two triangular plates 122 that are fixedly connected to the bottom of the large-aperture filter screen 121, and the adjacent sides of the two triangular plates 122 begin to have strip grooves 123, and a small-aperture filter screen 124 is slidably connected between the inner walls of the two strip grooves 123. A disassembly groove is provided on the front face of the seedling box, and the disassembly groove is adapted to the small-aperture filter screen 124.

[0049] Open the cylinder 125, and the cylinder 125 lifts the large-aperture filter screen 121 and the small-aperture filter screen 124 through the steering rod 126, so that the larger fry will be located above the large-aperture filter screen 121, and the smaller fry will be located above the small-aperture filter screen 124. The small-aperture filter screen 124 is taken out and weighed through the disassembly slot. Finally, the weight of the small-aperture filter screen 124 itself is subtracted to obtain the weight of the small fry. The total weight of the small fry can be divided by the weight of a single small fry to estimate the number of the entire small fry. Since the large-aperture filter screen 121 is arranged to be inclined, the large fry enter the fish bucket 131.

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

[0051] By providing the water level tank 150 , a certain water level is maintained inside the sorting box 140 , thereby preventing the overly high water level from affecting the turning of the turning plate 312 , thereby improving counting accuracy.

[0052] The implementation principle of the embodiment of the present invention is as follows: when in use, the fry are inside the frying box, the cylinder 125 is opened, and the cylinder 125 lifts the large-pore filter screen 121 and the small-pore filter screen 124 through the steering rod 126, so that the large fry with a body size greater than 4 cm will be located above the large-pore filter screen 121, and the small fry with a body size less than 4 cm will be located above the small-pore filter screen 124. The small-pore filter screen 124 is taken out and weighed through the disassembly slot, and finally the weight of the small-pore filter screen 124 itself is subtracted to obtain the weight of the small fry. The total weight of the small fry is divided by the weight of a single small fry to estimate the number of the entire small fry. Since the large-pore filter screen 121 is tilted, the large fry enters the fish bucket 131, and the water pump 134 is turned on to pass water through the water pump 134. The pump 134 draws water into the water pipe 133, and water is poured into the fish bucket 131 through the water pipe 133. The water will be discharged through the introduction channel 132. The introduction channel 132 is set to a state that is only convenient for a single fry to pass through, so that the fry follow the water flow and pass through the introduction channel 132 in sequence. The fry pass through the introduction channel 132 in a parade state. The two drive motors 225 are turned on. The two drive motors 225 will drive two of the auxiliary rollers 222 to make the two transmission belts 223 roll, thereby making the two sponge belts 224 roll. The fry will enter between the two sponge belts 224 and be located between the two bevel grooves. The two sponge belts 224 assist the fry to move between the two bevel grooves. When the fry cannot be supported by the two bottom plates 210, it will When the fry falls to the corresponding sorting box 140 below, the fry will be classified more finely. When the fry falls, the fry will pass through the flip plate 312, and the flip plate 312 will drive the rotating shaft rod 311 to rotate. When the rotating shaft rod 311 rotates, it will drive the incomplete bevel gear 313 to rotate. The incomplete bevel gear 313 drives the annular bevel gear 324. The annular bevel gear 324 will push the first ratchet bar 326 through the annular ratchet groove 325. The first ratchet bar 326 will drive the inner wheel 323 to rotate. When the inner wheel 323 rotates, it will drive the inner shaft 321 to rotate. At this time, the digital roller 330 and the ratchet 3210 rotate. When the ratchet 3210 rotates, it will push the second ratchet bar 329 to move. At this time, the second torsion spring 322 is tightened, and the digital roller 330 and the ratchet 3210 rotate. 30 rotates to switch the digital face, and subsequently the first torsion spring 314 will drive the incomplete bevel gear 313 to rotate and reset, and the second ratchet bar 329 and the ratchet wheel 3210 will limit the rotation direction of the inner shaft 321, so that the incomplete bevel gear 313 will push the annular bevel gear 324 to rotate, and the annular ratchet groove 325 will push the first ratchet bar 326 to contract and the annular bevel gear 324 to idle, and the auxiliary transport component 220 will run continuously to continuously sort the fry, and each digital roller 330 will respectively display the number of fry of corresponding volume. Subsequently, the numbers displayed by multiple digital rollers 330 can be added to know the total number of fry, and the counting is completed, so that the synchronous coordination of multi-level refined sorting of fry and automatic counting can be achieved.Refined differentiation can facilitate subsequent accurate feeding and health management decisions. After the counting is completed, the sorting box 140 can be pulled to the other side to take out the finely sorted fry. When sorting larger fry, since the sorting boxes 140 are arranged in sequence, the first sorting box 140 stores fry of 4 to 5 cm, the second stores fry of 5 to 6 cm, the third stores fry of 6 to 7 cm, and so on. When the count of the digital roller 330 needs to be cleared, the staff can pull the pull plate 450 downward, and the pull plate 450 will drive 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, and the pull rod 3212 will drive the second ratchet When bar 329 descends and separates from ratchet 3210, second torsion spring 322 drives inner shaft 321 to reset, thereby resetting multiple digital rollers 330. This makes resetting digital rollers 330 more convenient and uniform. The digital rollers generate real-time fry size distribution data, which staff can directly upload to the smart fishery management system for easier fry management. At the same time, the improved counting efficiency and automated operation mode effectively reduce labor costs and subjective errors, promoting the development of aquaculture towards intelligent and precise control. This provides key equipment support for the industry goals of "precise aquaculture decision-making, efficient resource utilization, and full digital management" in smart fisheries, accelerating the transformation of traditional aquaculture to intelligent control.
