Description

Technical Field

[0001] This invention relates to the field of fish fry farming technology, specifically to a sorting device and sorting method for fish fry farming. Background Technology

[0002] In the fish fry farming industry, the quality and size consistency of fish fry are crucial to the success of the farming. Fish fry of different sizes vary significantly in terms of growth rate, feeding ability, and adaptability to the environment. If fish fry of different sizes are mixed for farming, larger fish fry may compete for food resources and living space, causing smaller fish fry to grow slowly or even die, thus affecting the overall farming efficiency and fish fry survival rate. Since fish fry of different sizes have different feed requirements and intake capabilities, it is necessary to sort the fish fry to facilitate feeding appropriate feed according to the size and growth stage of the fish fry, improve feed utilization, reduce feed waste, and lower farming costs. At the same time, sorted fish fry are easier to manage, such as water quality regulation and disease prevention, which can be carried out more targetedly, improving management efficiency and reducing management difficulty.

[0003] Existing fish fry sorting devices typically involve directly pouring batches of fry into a sorting cylinder. The fry are then sorted by passing through sieves of different sizes. As the fry swim inside the cylinder, some drift away from the sieves, leaving smaller fry behind and affecting the sorting efficiency. Furthermore, a significant amount of dirt remains inside the cylinder after sorting, requiring cleaning. However, since the sorting cylinder is generally a single unit, it is difficult to disassemble, leading to incomplete cleaning. Therefore, improvements are needed.

[0004] Based on this, the present invention designs a sorting device and sorting method for fish fry farming to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a sorting device and method for fish fry farming, in order to solve the problems mentioned in the background art. In existing fish fry farming sorting devices, when sorting fish fry, a batch of fish fry is generally poured directly into the sorting cylinder. The fish fry are sorted by passing through screens of different sizes. The fish fry swim inside the sorting cylinder. Some fish fry move away from the screens while swimming, which can easily cause smaller fish fry to remain inside the sorting cylinder, affecting the sorting effect. At the same time, after sorting, a lot of dirt remains inside the sorting cylinder, which needs to be cleaned. Since the sorting cylinder is generally a one-piece design, it is difficult to disassemble, which can easily lead to incomplete cleaning of the sorting cylinder.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

The trapezoidal blocks are slidably connected to the top of the storage slot, and the positions of the trapezoidal blocks and the trapezoidal slots are corresponding and the same in shape.

[0011] As a further embodiment of the present invention, a limiting plate is fixedly installed on the surface of the connecting rod located at the top of the inner side of the mounting groove, a fixing spring is sleeved on the surface of the connecting rod located at the bottom of the limiting plate, and the fixing spring is movably installed inside the mounting groove. A lever is fixedly installed at the bottom end of the connecting rod, extending through the mounting groove into the moving groove. A connecting strip is fixedly installed at one end of the two levers, extending through the moving groove to the outside of the mounting frame.

[0012] As a further embodiment of the present invention, a concave seat is fixedly installed at the center of one side surface of the mounting bracket. A fixing plate is rotatably installed inside the concave seat via a pin. The bottom of one side of the fixing plate is engaged with a connecting strip. Two positioning pins are fixedly installed on the top of the opposite side of the mounting bracket and the fixing plate, and anti-disengagement sleeves are fixedly installed on the opposite side of the mounting bracket and the fixing plate on the surface of the positioning pins. A return spring is sleeved between the two opposite positioning pins, and the two ends of the return spring are engaged inside the anti-disengagement sleeve.

[0013] As a further embodiment of the present invention, a bevel gear one is fixedly installed at the output end of the rotating motor, the agitation mechanism includes an agitation shaft, the bottom end of the agitation shaft is rotatably connected to the center position of the bottom of the sorting tank through a bearing, the top end of the agitation shaft is rotatably connected to a triangular plate through a bearing, a bevel gear two is fixedly installed through the triangular plate at the top end of the agitation shaft, and the bevel gear two meshes with the bevel gear one, and six arc-shaped agitation plates are fixedly installed at equal angles on the surface of the agitation shaft located at the bottom of the triangular plate.

[0014] As a further embodiment of the present invention, positioning inserts are fixedly installed on both sides of the arc-shaped screen plate, and the positioning inserts have the same shape as the positioning slots. A T-shaped slot is provided through one side of the positioning insert, and the T-shaped slot is slidably connected to the surface of the T-shaped card strip. A shielding top plate is fixedly installed on one side of the top of the arc-shaped screen plate between the two positioning inserts.

[0015] As a further embodiment of the present invention, the clamping mechanism includes an arc-shaped mounting slide rod, with fixed end plates fixedly mounted at both ends of the arc-shaped mounting slide rod. Two sliding plates are slidably mounted through the surface of the arc-shaped mounting slide rod between the two fixed end plates, and the sliding plates are in contact with the surface of the sorting cylinder. Fixed pressure plates are fixedly mounted on the top of the two sliding plates, and an arc-shaped spring is sleeved on one side of the arc-shaped mounting slide rod located on the sliding plate.

[0016] A sorting method for a fish fry sorting device, the sorting method comprising the following steps:

[0017] Select a suitable arc-shaped screen plate according to the fish fry sorting requirements. Push the arc-shaped spring to drive the sliding plate to slide on the surface of the corresponding arc-shaped mounting rod, so that the arc-shaped spring is squeezed and deformed on the surface of the arc-shaped mounting rod until the fixed pressure plate is removed from the top of the positioning slot. Insert the positioning strips on both sides of the arc-shaped screen plate into the corresponding positioning slots, so that the T-shaped slot on one side of the positioning strip is tightly stuck to the surface of the corresponding T-shaped clip, until the arc-shaped screen plate is completely inserted into the inner wall of the sorting tank. Release the fixed pressure plate and under the rebound action of the arc-shaped spring, lift the sliding plate to slide on the surface of the arc-shaped mounting rod, so that the fixed pressure plate covers and adheres tightly to the top of the shielding top plate.

[0018] Next, insert the discharge seat into the placement slot. The discharge seat moves the mounting bracket closer to the placement slot. Press the fixing plate to rotate around the concave seat, so that the bottom of the fixing plate moves away from the connecting strip. When the trapezoidal block is in close contact with the top of the placement slot, the top of the placement slot compresses the trapezoidal block into the storage slot. Control the connecting rod to move the limiting plate down in the installation slot, compressing the fixing spring until the discharge seat is fully inserted into the placement slot, so that the trapezoidal block and the trapezoidal slot are aligned. Under the rebound of the fixing spring, the limiting plate is lifted, so that the connecting rod moves up in the installation slot, moving the trapezoidal block from the storage slot and into the trapezoidal slot. At the same time, the connecting rod, driven by the lever, controls the connecting strip to move up and engage with the fixing plate, thereby clamping and fixing the connecting strip, and clamping and fixing the trapezoidal block in the trapezoidal slot, ensuring that the discharge seat will not come out of the placement slot.

[0019] The electric push rod extends and lifts the second rotating seat, causing the rotating top bar to rotate between the first and second rotating seats. This lifts the discharge baffle, which is pressed tightly against the top of the placement trough, blocking the first discharge outlet. An appropriate amount of fish fry is poured into the sorting trough. Simultaneously, the rotating motor is started to control the first bevel gear to rotate at a low speed. Under the meshing action of the first and second bevel gears, the stirring shaft drives the arc-shaped stirring plate to rotate at a low speed inside the sorting trough, pushing the fish fry to swim inside. Fish fry smaller than the arc-shaped screen mesh are discharged from the second discharge outlet, while fish fry larger than the arc-shaped screen mesh continue to swim inside the sorting trough. After the small fish fry are discharged, the electric push rod retracts, causing the second rotating seat to move. Under the pull of the rotating top bar, the discharge baffle begins to rotate away from the first discharge outlet, causing the larger fish fry inside the sorting trough to fall from the first discharge outlet into the discharge seat and then be discharged from the opening of the discharge seat, thus achieving the sorting of fish fry.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This invention comprises a rotating motor, an arc-shaped stirring plate, an arc-shaped screen plate, a fixed pressure plate, and an arc-shaped spring. The fixed pressure plate rotates at the top of the sorting cylinder, causing a sliding plate to slide on the corresponding arc-shaped mounting rod surface. This compresses the arc-shaped spring, deforming it and inserting the arc-shaped screen plate tightly against the inner wall of the sorting tank. The positioning strips on both sides of the arc-shaped screen plate are then inserted into their corresponding positioning slots until the T-shaped slots are engaged with the corresponding T-shaped locking strips. Releasing the fixed pressure plate allows the arc-shaped spring to rebound, lifting the sliding plate and resetting it on the arc-shaped mounting rod surface. This allows the fixed pressure plate to cover the top of the shielding plate, thus securing the arc-shaped screen plate firmly to the inner wall of the sorting tank, facilitating sorting according to the desired results. Select the appropriate arc-shaped screen plate to replace, aligning it with the position of outlet two. Pour an appropriate amount of fish fry into the sorting tank, start the rotating motor, and through the meshing transmission of bevel gear one and bevel gear two, control the stirring shaft to drive the arc-shaped stirring plate to rotate inside the sorting tank, pushing the fish fry to swim close to the arc-shaped screen plate inside the sorting tank. After being sorted by the mesh of the arc-shaped screen plate, the smaller fish fry are discharged from outlet two. After the small fish fry are discharged, control the electric push rod to retract, driving the discharge baffle to rotate at the bottom of outlet one, opening outlet one to discharge the larger fish fry remaining inside the sorting tank, thereby improving the sorting efficiency of fish fry.

[0022] 2. This invention comprises a placement slot, a trapezoidal slot, a discharge seat, a trapezoidal block, a fixing spring, a connecting strip, and a fixing plate. Pressing the fixing plate disengages it from the connecting strip, allowing the discharge seat to be inserted into the placement slot. The trapezoidal block is then inserted into the placement slot, pressed against the top of the slot. The top of the placement slot presses down on the trapezoidal block, pushing it into the receiving slot. This causes the connecting rod to move downwards within the installation slot, deforming the fixing spring within the installation slot until the discharge seat is fully inserted into the placement slot, allowing the trapezoidal block to... The trapezoidal locking block corresponds to the position of the trapezoidal locking slot. Under the rebound action of the fixed spring, the limiting plate is lifted, causing the connecting rod to move upward and drive the trapezoidal locking block to disengage from the storage slot and lock into the trapezoidal locking slot. At the same time, the connecting rod is driven by the lever to move the connecting strip upward and engage with the fixed locking plate, thus locking and fixing the connecting strip. This makes the trapezoidal locking block locked and fixed inside the trapezoidal locking slot, thereby locking and fixing the discharge seat inside the placement slot. This makes it convenient to lock and fix the discharge seat inside the placement slot or to remove it for thorough cleaning of the discharge seat and the sorting cylinder.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-8 The present invention provides a technical solution:

[0036] A sorting device for fish fry farming includes a sorting cylinder 1, a sorting groove 104 at the top of the sorting cylinder 1, and a placement groove 101 at the bottom of the sorting cylinder 1. A discharge seat 2 is horizontally slidably installed inside the placement groove 101, penetrating the inside and outside of the sorting cylinder. A discharge outlet 102 is provided on one side of the top of the placement groove 101, and the sorting groove 104 is connected to the placement groove 101 through the discharge outlet 102. A discharge baffle 201 is rotatably installed on one side of the top of the inner wall of the discharge seat 2 via a pin. A rotating seat 202 is symmetrically fixedly installed at the bottom of the discharge baffle 201. A rotating top bar 203 is rotatably installed at the bottom of the rotating seat 202 via a pin. A rotating seat 204 is rotatably installed at the bottom of the rotating top bar 203 via a pin. An electric push rod 205 is fixedly installed on one side of the rotating seat 204, and the other end of the electric push rod 205 is fixedly connected to the inner wall of the discharge seat 2.

[0037] When discharging the remaining fish fry inside the sorting tank 104, the electric push rod 205 is controlled to retract, causing the rotating top bar 203 to rotate between the rotating seat 1 202 and the rotating seat 2 204, pulling the discharge baffle 201 to rotate and open at the bottom of the discharge outlet 102, thereby discharging the remaining fish fry inside the sorting tank 104; after the fish fry are discharged, the electric push rod 205 is controlled to extend, pushing the rotating seat 2 204 to lift the rotating top bar 203, causing the rotating top bar 203 to lift the discharge baffle 201 to rotate and move closer to the discharge outlet 102, blocking the discharge outlet 102, thereby ensuring that the fish fry will not be discharged from the discharge outlet 102 when the sorting tank 104 is sorting the fish fry.

[0038] As a further embodiment of the present invention, a fixing mechanism 3 is fixedly installed on one side of the discharge seat 2. The fixing mechanism 3 includes a mounting frame 301. The mounting frame 301 has symmetrical mounting grooves 302 on both sides inside. The top of the mounting frame 301 has a storage groove 304. A connecting rod 305 is slidably installed through the mounting groove 302. The top ends of the two connecting rods 305 extend through the mounting groove 302 to the storage groove 304 and are fixedly installed with trapezoidal locking blocks 310. A trapezoidal locking groove 103 is provided on the side of the top of the placement groove 101 located at the discharge outlet 102, and the trapezoidal locking block 310 is slidably connected to the top of the storage groove 304. The trapezoidal locking block 310 and the trapezoidal... The slots 103 are in corresponding positions and have the same shape; the connecting rod 305 is fixedly mounted on the top surface of the inner side of the mounting slot 302 with a limiting plate 306, and the connecting rod 305 is fitted with a fixing spring 307 on the bottom surface of the limiting plate 306, and the fixing spring 307 is movably mounted inside the mounting slot 302. The bottom end of the connecting rod 305 passes through the mounting slot 302 and extends into the moving slot 303, where a lever 308 is fixedly mounted. One end of the two levers 308 passes through the moving slot 303 and extends to the outside of the mounting frame 301, where a connecting strip 309 is fixedly mounted. The levers 308 can move at the straight opening of the moving slot 303 on the surface of the mounting frame 301.

[0039] When the fixing mechanism 3 is inserted into the placement slot 101 along with the discharge seat 2, the trapezoidal locking block 310 is pressed into the storage slot 304 by the top of the placement slot 101. This causes the trapezoidal locking block 310 to drive the connecting rod 305 to slide inside the mounting slot 302, compressing the fixing spring 307 to deform at the bottom of the limiting plate 306 until the discharge seat 2 is fully inserted into the placement slot 101. After the trapezoidal locking block 310 and the trapezoidal slot 103 are aligned, the fixing spring 307 rebounds and pushes the limiting plate 306 upward, causing the connecting rod 305 to move upward and drive the trapezoidal locking block 310 to move upward and disengage from the storage slot 304 and engage inside the trapezoidal slot 103, thereby clamping and fixing the discharge seat 2 inside the placement slot 101.

[0040] As a further embodiment of the present invention, a concave seat 311 is fixedly installed at the center of one side surface of the mounting bracket 301. A fixing plate 312 is rotatably installed inside the concave seat 311 via a pin. A slot is provided at the bottom of one side of the fixing plate 312 to engage with the connecting strip 309. Two positioning pins 313 are fixedly installed on the top of the opposite side of the mounting bracket 301 and the fixing plate 312, and anti-detachment sleeves 314 are fixedly installed on the opposite side of the mounting bracket 301 and the fixing plate 312 on the surface of the positioning pins 313. A return spring 315 is sleeved between the two opposite positioning pins 313, and the two ends of the return spring 315 are locked inside the anti-detachment sleeve 314.

[0041] Pressing the top of the fixing plate 312 causes the return spring 315 to deform between the corresponding positioning pins 313. At the same time, the fixing plate 312 rotates around the connection position with the concave seat 311, causing the bottom of the fixing plate 312 to disengage from the connecting strip 309, thus facilitating the control of the connecting strip 309 to move the connecting rod 305. After the connecting strip 309 moves the lever 308 to the top of the moving groove 303, the fixing plate 312 is released and, under the rebound action of the return spring 315, the fixing plate 312 is pushed up to reset, so that the bottom of the fixing plate 312 engages with the connecting strip 309, thus securing the connecting strip 309 and ensuring that the connecting rod 305 does not slide freely inside the mounting groove 302. This prevents the trapezoidal block 310 from moving down and disengaging from the trapezoidal slot 103, causing the discharge seat 2 to slide freely inside the placement groove 101.

[0042] As a further embodiment of the present invention, a triangular plate 4 is fixedly installed on the top of the inner wall of the sorting tank 104, a rotating motor 5 is fixedly installed on one side of the top of the triangular plate 4, an agitation mechanism 6 is rotatably installed between the bottom of the sorting tank 104 and the center of the bottom of the triangular plate 4 via a bearing, and an arc-shaped screen plate 7 is symmetrically and slidably installed through both sides of the inner wall of the sorting tank 104.

[0043] A bevel gear 501 is fixedly installed at the output end of the rotating motor 5. The stirring mechanism 6 includes a stirring shaft 601. The bottom end of the stirring shaft 601 is rotatably connected to the center position of the bottom of the sorting tank 104 through a bearing. The top end of the stirring shaft 601 is rotatably connected to the triangular plate 4 through a bearing. A bevel gear 603 is fixedly installed through the triangular plate 4 at the top end of the stirring shaft 601, and the bevel gear 603 meshes with the bevel gear 501. Six arc-shaped stirring plates 602 are fixedly installed at equal angles on the surface of the stirring shaft 601 at the bottom of the triangular plate 4.

[0044] After pouring an appropriate amount of fish fry into the sorting tank 104, start the rotating motor 5 to control the bevel gear 501 to rotate. Under the meshing action of the bevel gear 501 and the bevel gear 603, the rotation of the rotating motor 5 is transmitted to the stirring shaft 601. The stirring shaft 601 drives the arc-shaped stirring plate 602 to rotate at a low speed inside the sorting tank 104, so that the arc-shaped stirring plate 602 pushes the fish fry to swim inside the sorting tank 104, thereby improving the efficiency of fish fry sorting.

[0045] As a further embodiment of the present invention, discharge outlets 105 are symmetrically provided on both sides of the inner wall of the sorting tank 104, and positioning slots 106 are symmetrically provided on both sides of the discharge outlets 105 on the inner wall of the sorting tank 104. T-shaped clips 107 are fixedly installed on the inner wall of the positioning slots 106. Positioning inserts 701 are fixedly installed on both sides of the arc-shaped screen plate 7, and the positioning inserts 701 have the same shape as the positioning slots 106. A T-shaped slot 702 is provided through one side of the positioning insert 701, and the T-shaped slot 702 is slidably connected to the surface of the T-shaped clips 107. A shielding top plate 703 is fixedly installed on one side of the top of the arc-shaped screen plate 7 between the two positioning inserts 701.

[0046] Align the positioning insert 701 with the positioning slot 106, insert the arc-shaped screen plate 7 close to the inner wall of the sorting groove 104, insert the positioning insert 701 into the positioning slot 106, and ensure that the T-shaped slot 702 is locked on the surface of the corresponding T-shaped clip 107 until the arc-shaped screen plate 7 is fully inserted into the sorting groove 104, ensuring that the arc-shaped screen plate 7 will not be misaligned or deflected when installed on the inner wall of the sorting groove 104.

[0047] As a further embodiment of the present invention, a clamping mechanism 8 is symmetrically fixedly installed on the top of the outer surface of the sorting cylinder 1. The clamping mechanism 8 includes an arc-shaped mounting slide rod 801. Fixed end plates 802 are fixedly installed at both ends of the arc-shaped mounting slide rod 801. The fixed end plates 802 are fixed to the top of the sorting cylinder 1. Two sliding plates 803 are slidably installed through the surface of the arc-shaped mounting slide rod 801 between the two fixed end plates 802. The sliding plates 803 are in contact with the surface of the sorting cylinder 1. Fixed pressure plates 804 are fixedly installed on the top of the two sliding plates 803. An arc-shaped spring 805 is sleeved on one side of the arc-shaped mounting slide rod 801 located on the sliding plate 803.

[0048] The fixed pressure plate 804 is pushed to rotate at the top of the sorting cylinder 1, causing the sliding plate 803 to slide on the surface of the arc-shaped mounting slide rod 801, compressing the arc-shaped spring 805 and deforming it. After the fixed pressure plate 804 moves away from the positioning slot 106, the arc-shaped screen plate 7 is inserted into the sorting groove 104 accordingly. The fixed pressure plate 804 is released, and under the rebound action of the arc-shaped spring 805, the sliding plate 803 is lifted and slides on the surface of the arc-shaped mounting slide rod 801, causing the fixed pressure plate 804 to rotate at the top of the sorting cylinder 1 and reset to stick to the top of the shielding top plate 703, pressing and fixing the arc-shaped screen plate 7 inside the sorting groove 104, ensuring that the arc-shaped screen plate 7 is stuck inside the sorting groove 104 and will not be pulled out at will.

[0049] A sorting method for a sorting device used in fish fry rearing, the sorting method comprising the following steps:

[0050] Select a suitable arc-shaped screen plate 7 according to the fish fry sorting requirements, push the arc-shaped spring 805 to drive the sliding plate 803 to slide on the surface of the corresponding arc-shaped mounting slide rod 801, so that the arc-shaped spring 805 is squeezed and deformed on the surface of the arc-shaped mounting slide rod 801 until the fixed pressure plate 804 is removed from the top of the positioning slot 106, insert the positioning strips 701 on both sides of the arc-shaped screen plate 7 into the corresponding positioning slot 106, so that the T-shaped slot 702 on one side of the positioning strip 701 is tightly stuck on the surface of the corresponding T-shaped clip 107, until the arc-shaped screen plate 7 is completely inserted into the inner wall of the sorting groove 104, release the fixed pressure plate 804, and under the rebound action of the arc-shaped spring 805, lift the sliding plate 803 to slide on the surface of the arc-shaped mounting slide rod 801, so that the fixed pressure plate 804 covers and adheres tightly to the top of the shielding top plate 703;

[0051] Next, insert the discharge seat 2 into the placement slot 101. The discharge seat 2 drives the mounting bracket 301 closer to the placement slot 101, pressing the fixing plate 312 to rotate around the concave seat 311, so that the bottom of the fixing plate 312 moves away from the connecting strip 309. When the trapezoidal block 310 is in close contact with the top of the placement slot 101, the top of the placement slot 101 compresses the trapezoidal block 310 into the storage slot 304. The control connecting rod 305 drives the limiting plate 306 to move down inside the mounting slot 302, compressing the fixing spring 307 until the discharge seat 2 is fully inserted into the placement slot 101, so that the trapezoidal block 310 is in close contact with the top of the placement slot 101. The trapezoidal locking block 310 is positioned corresponding to the trapezoidal locking groove 103. Under the rebound action of the fixing spring 307, the limiting plate 306 is lifted, causing the connecting rod 305 to move upward in the mounting groove 302. This causes the trapezoidal locking block 310 to move upward from the storage groove 304 and lock into the trapezoidal locking groove 103. At the same time, the connecting rod 305, driven by the lever 308, controls the connecting strip 309 to move upward and engage with the fixing plate 312, thereby clamping and fixing the connecting strip 309. This ensures that the trapezoidal locking block 310 is clamped and fixed inside the trapezoidal locking groove 103, ensuring that the discharge seat 2 inserted into the placement groove 101 will not come off at will.

[0052] The electric push rod 205 extends and lifts the rotating seat 204, causing the rotating top bar 203 to rotate between the rotating seat 1 202 and the rotating seat 204. This lifts the discharge baffle 201, which is pressed tightly against the top of the placement trough 101, blocking the discharge outlet 102. An appropriate amount of fish fry is then poured into the sorting trough 104. Simultaneously, the rotating motor 5 is started to control the bevel gear 501 to rotate at a low speed. Under the meshing action of the bevel gear 501 and the bevel gear 2 603, the stirring shaft 601 drives the arc-shaped stirring plate 602 to rotate at a low speed inside the sorting trough 104, pushing the fish... The fry swim inside the sorting tank 104. Fry smaller than the mesh size of the arc-shaped sieve plate 7 are discharged from the outlet 2 105. Fry larger than the mesh size of the arc-shaped sieve plate 7 continue to swim inside the sorting tank 104. After the small fry are discharged, the electric push rod 205 is controlled to retract, which drives the rotating seat 204 to move. Under the pull of the rotating top bar 203, the discharge baffle 201 begins to rotate away from the outlet 102, so that the larger fry inside the sorting tank 104 fall from the outlet 102 into the discharge seat 2 and are discharged from the opening of the discharge seat 2, thereby achieving the sorting of fry.
