Description
Technical Field
[0001] This utility model relates to the field of eel farming technology, and in particular to a transmission system for screening live eels. Background Technology
[0002] In eel farming, eels of different sizes need to be graded and screened to select high-quality, fresh eels, thereby improving the quality of eel farming and increasing the eel sales rate. From the eel farming pond to the eel screening device, after screening, eels of different sizes are placed in different temporary holding tanks.
[0003] Eels of different sizes in different holding tanks need to be transferred to different rearing tanks for separate rearing. The holding tanks are usually lower than the rearing tanks. Using an eel lifting device, eels of the same size are first lifted to a certain height, and then the eels enter the different rearing tanks through guide troughs.
[0004] However, during the lifting and lowering process of the eel, the height difference or connection seam between the lifting device and the guide groove can easily cause damage to the eel during handling. Utility Model Content

[0010] Furthermore, one end of the slide is hinged to the box body, and the other end of the slide is disposed opposite to the guide groove. The slide has an unfolded state and a retracted state. In the unfolded state, the end of the slide away from the box body overlaps in the guide groove; in the retracted state, the end of the slide away from the box body flips and abuts against the box body.
[0011] Furthermore, a constraint unit is provided between the housing and the slide, which can constrain the slide so that the slide remains in a retracted state.
[0012] Furthermore, the locking unit includes a first insertion guide groove and a blocking member that are fixedly connected to the housing. The first insertion plate is slidably inserted into the first insertion guide groove, and the blocking member is disposed between the first insertion guide groove and the first insertion plate to prevent the first insertion plate from opening relative to the first insertion guide groove.
[0013] Furthermore, the bottom of the box is provided with a water-permeable bottom plate, and the two sides of the bottom plate are recessed relative to the middle to form a recessed part, and the end of the recessed part away from the first insert plate is inclined relative to the end of the first insert plate.

[0033] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.
[0034] This embodiment describes a transmission system for screening live eels, which relates to the field of eel farming technology. By setting a rotatable chute 120 between the box 110 and the receiving pool 300, the box 110 and the receiving pool 300 can be smoothly connected, avoiding damage to the eels when they are transferred between the two.
[0035] Please see Figures 1 to 7This embodiment discloses a transfer system for screening live eels, comprising a lifting assembly 100, a holding tank 200, and a receiving tank 300. The lifting assembly 100 includes a liftable housing 110, with an opening on one side for transferring eels. A rotatable chute 120, a first switching unit 130, and a locking unit 140 are provided on the side of the housing 110 opposite the opening. The first switching unit 130 includes a slidingly inserted first plate 131 for controlling the opening and closing of the channel between the housing 110 and the chute 120. When the housing 110 moves, the first plate 131 closes the channel, protecting the eels and preventing them from escaping from the housing 110. When the housing 110 stops at a set height, the first plate 131 opens the channel, connecting the housing 110 to the guide chute 310, facilitating the transfer of eels. The locking unit 140 is located between the first insert plate 131 and the box 110, which can prevent a large number of eels from opening the first insert plate 131 when they struggle and twist in the box 110, thus preventing the eels from falling from a height and effectively protecting the eels.
[0036] The holding tank 200 can transport eels to the lower-level tank 110.
[0037] The receiving pool 300 includes a guide trough 310 for receiving eels from the elevated enclosure 110 and multiple slides 320. The guide trough 310 receives eels moved to the elevated enclosure 110, and the multiple slides 320 are connected to the guide trough 310. The guide trough 310 is positioned relative to the bottom of the slide 120, which can tilt to connect the guide trough 310 and the enclosure 110. The slide 120 can overcome the height difference and seam between the guide trough 310 and the enclosure 110, smoothly connecting the enclosure 110 and the guide trough 310, providing cushioning and protection for the eels during movement, reducing the impact of falling eels, and preventing injury. The multiple slides 320 can be opened and closed independently as needed, thereby transporting eels of different sizes to different rearing pools for separate rearing of eels of different sizes.
[0038] In the specific implementation process, the side of the housing 110 is rotatably connected to the slide 120. Specifically, this can be achieved using a single-sided hinge in conjunction with a flip-up guide groove. The other end of the slide 120 is positioned relative to the guide groove 310. The slide 120 has an unfolded state and a retracted state. In the unfolded state, the end of the slide 120 away from the housing 110 overlaps with the guide groove 310, forming an inclined slide 320. In the retracted state, the end of the slide 120 away from the housing 110 flips and abuts against the housing 110, achieving a close fit between the slide 120 and the side wall of the housing 110, thus avoiding occupying working space.
[0039] The first insert plate 131 is slidably inserted into the housing 110. Specifically, the housing 110 is provided with a gate structure that moves in the vertical direction. This can be achieved by using a metal plate with a guide rail. The opening and closing of the channel is controlled by pushing and pulling.
[0040] Specifically, the box 110 moves vertically via a lifting mechanism. When in its lower position, eels are loaded into the holding tank 200. The locking unit 140 automatically locks when the insert plate closes, preventing accidental opening of the channel due to vibration during lifting. After the box 110 rises to its higher position, the slide 120 unfolds to form an inclined channel. When the first insert plate 131 opens, the eels slide into the slide 120 along the recess 111a of the bottom plate 111. The inclined angle of the slide 120 allows the eels to slide into the guide trough 310 at a controllable speed. The multiple slides 320 connected to the guide trough 310 can be selectively opened according to sorting requirements, achieving the classified output of eels of different sizes.
[0041] It should be noted that the unfolding angle of the slide 120 can be adjusted by the rotation angle of the hinge structure, with an adjustment range of 30° to 60°, to adapt to the docking requirements of guide grooves 310 of different heights.
[0042] In some embodiments, please refer to Figure 5 A constraint unit 150 is provided between the housing 110 and the slide 120. The constraint unit 150 can constrain the slide 120 so that the slide 120 remains in a closed state. The constraint unit 150 is a structural component used to limit the position of the slide 120. Specifically, it can be implemented by mechanical lock, magnetic attraction device, snap-fit mechanism or strap. Its function is to prevent the slide 120 from being displaced due to external force or vibration in the non-operating state by physical restriction.
[0043] The retracted state refers to the fixed state in which the end of the chute 120 away from the box 110 is flipped and pressed against the side wall of the box 110. This can be achieved by using a hinge and a limiting structure. Its function is to reduce the space occupied by the chute 120 during transportation or non-sorting stages and to prevent the chute 120 from accidentally unfolding and causing eel leakage or equipment collision.
[0044] Specifically, the chute 120 is connected to the housing 110 via a hinge. In the folded state, the restraint unit 150 secures the end of the chute 120 away from the housing 110 to the side wall of the housing 110 via a locking or snap-fit mechanism. When the chute 120 needs to be unfolded, the operator must manually release the locking state of the restraint unit 150, allowing the chute 120 to rotate around the hinge to the unfolded position. After the sorting operation is completed, the chute 120 can be flipped back to the folded state and automatically or manually locked by the restraint unit 150 to ensure the stability of the chute 120 during movement or storage.
[0045] Compared with existing technologies, the chute 120 in existing eel sorting devices typically lacks a fixed constraint structure. During equipment lifting or transportation, the chute 120 may accidentally unfold due to shaking, causing eels to fall or the equipment to be damaged. This application adds a constraint unit 150 to keep the chute 120 in a fixed shape when not in use, reducing the operational risks caused by displacement of the chute 120.
[0046] In some embodiments, please refer to Figure 5 The locking unit 140 includes a first insertion guide groove 141 fixedly connected to the housing 110 and an obstruction member 142. The first insertion plate 131 is slidably inserted into the first insertion guide groove 141, and the obstruction member 142 is disposed between the first insertion guide groove 141 and the first insertion plate 131 to prevent the first insertion plate 131 from opening relative to the first insertion guide groove 141.
[0047] In specific implementation, the first insertion guide groove 141 is a groove-shaped structure fixedly connected to the housing 110. It can be made of metal or plastic and is used to accommodate the sliding insertion of the first insertion plate 131. A guide rail can be set inside to constrain the movement trajectory of the first insertion plate 131. The obstruction member 142 is a limiting component set between the insertion guide groove and the insertion plate. It can be implemented by a spring, elastic block or friction plate. It prevents the accidental displacement of the first insertion plate 131 under non-human operation through elastic deformation or frictional resistance.
[0048] As an alternative implementation, the obstruction 142 can also be implemented using a spring pin and positioning hole mating structure, which automatically locks when the insert plate is closed.
[0049] Meanwhile, the obstruction 142 can also be a rope, which can be used to directly tie the box 110 and the first insert plate 131 to prevent the first insert plate 131 from coming out.
[0050] Specifically, when the first insert plate 131 slides along the guide track of the first insertion guide groove 141, the obstruction member 142 applies a reverse force to the insert plate through elastic contact or frictional contact. When the insert plate is in the closed position, the resistance of the obstruction member 142 reaches its maximum value, at which point sufficient external force is required to overcome the resistance and open the insert plate. During the lifting and lowering process of the housing 110, even if subjected to vibration or impact, the obstruction member 142 can still maintain the relative position between the insert plate and the insertion guide groove, preventing abnormal opening of the channel and leakage of eels.
[0051] In some embodiments, please participate Figure 5 and Figure 6The bottom of the box 110 is provided with a water-permeable bottom plate 111. The two sides of the bottom plate 111 are recessed relative to the middle to form a recess 111a. The end of the recess 111a away from the first insert plate 131 is inclined relative to the end of the first insert plate 131. The recess 111a can gather all the eels, so that the eels have the intention to be output relative to the first insert plate 131. During the transfer of eels, the eels are prevented from being stuck in the box 110.
[0052] In the specific implementation process, the bottom plate 111 has multiple water-permeable holes. These holes allow water to flow through but prevent eels from passing through. This can be achieved using mesh or grid-like materials to drain accumulated water from the tank 110 during lifting and lowering, thus reducing weight. The recessed portion 111a refers to the groove structure formed by the downward curvature of the two side areas of the bottom plate 111 relative to the middle area. This can be formed through stamping or welding processes and is used to guide water flow and eels to gather towards the center. The inclined setting means that the side of the recessed portion 111a away from the first insert plate 131 forms a slope relative to the side closer to the first insert plate 131. This can be achieved using a sloping or arc-shaped transition structure to guide the eels to slide in a specific direction, reducing stagnation.
[0053] Specifically, when the tank 110 is raised or lowered, the bottom plate 111 drains internal water through a permeable structure, reducing the overall weight of the tank 110. The recessed design on both sides of the recessed part 111a concentrates the water flow and eels towards the center, preventing them from scattering and piling up. The sloped end of the recessed part 111a forms a ramp, allowing the eels to naturally slide into the guide groove 310 along the inclined direction when the slide 120 is opened, reducing collision damage caused by disorderly movement.
[0054] It should be noted that the entire housing 110 is a mesh grid structure, which can drain water from the housing 110 and reduce the burden on the lifting assembly 100.
[0055] In some embodiments, please refer to Figure 1 and Figure 2 Each slide 320 is provided with a second switch unit 330 between it and the guide groove 310. The second switch unit 330 includes a second insertion guide groove 331 and a second insertion plate 332 disposed on the slide 320. The second insertion plate 332 is slidably inserted into the second insertion guide groove 331. The second insertion plate 332 can be opened and closed independently as needed to guide the eels located in the guide groove 310 to different breeding ponds.
[0056] In practical implementation, the second insertion guide groove 331 is a guide structure fixed at the opening of the slide 320. It can be implemented using a U-shaped guide groove made of metal or plastic, and is used to guide the second insertion plate 332 to move along a straight trajectory. The second insertion plate 332 refers to a sliding baffle, which can be implemented using a smooth polypropylene sheet. It can be fully inserted into the second insertion guide groove 331 to close the slide 320, or partially pulled out to create a gap for the eel to pass through.
[0057] Specifically, when the slide 320 needs to be opened, the second insert plate 332 slides outward along the second insertion guide groove 331, forming a channel for the eel to enter the slide 320 from the guide groove 310; when the slide 320 needs to be closed, the second insert plate 332 is fully inserted into the second insertion guide groove 331 to block the channel. The second insertion guide groove 331 is provided at the connection between the slide 320 and the guide groove 310, so that the second insert plate 332 always maintains a tight fit with the wall of the slide 320 during the sliding process, preventing the eel from escaping through the gaps.
[0058] In some embodiments, please refer to Figures 1 to 3 The lifting assembly 100 includes a gantry frame 160 and a lifting and weighing unit 170. The two sides of the housing 110 are slidably engaged with the two sides of the gantry frame 160, which can limit the movement of the housing 110 and maintain its stability. The housing 110 is connected to the top of the gantry frame 160 via the lifting and weighing unit 170. The lifting and weighing unit 170 can both pull and lift the housing 110 and weigh the eels inside the housing 110.
[0059] In practical implementation, the portal frame 160 is a frame structure formed by the top crossbeam and the two side columns. It can be achieved by steel structure welding or bolt assembly, and is used to provide vertical guidance space for the lifting and lowering movement of the box 110. The lifting and weighing unit 170 is a lifting drive mechanism with integrated weighing function. It can be achieved by combining a winch and a weighing sensor, which measures the weight of the eels inside the box 110 in real time while controlling the lifting and lowering height of the box 110.
[0060] A limiting structure is formed between the side of the box 110 and the column of the portal frame 160 to limit the horizontal displacement of the box 110 during the lifting process.
[0061] Specifically, the enclosure 110 interacts with the column through a limiting structure, forming a vertical movement constraint. The lifting and weighing unit 170 is installed at the top crossbeam of the portal frame 160 and connected to the top of the enclosure 110 via steel cables or chains. It simultaneously collects weight data as the enclosure 110 is lifted and lowered along the guide rail. When the enclosure 110 is at its lowest position, the holding tank 200 loads the eels into the enclosure 110. The lifting and weighing unit 170 then raises the enclosure 110 to the target height and completes the weighing. Finally, the eels are transferred to the corresponding slide 320 for output via the slide 120.
[0062] In some embodiments, please refer to Figure 5 and Figure 7 The lifting assembly 100 also includes a limiting unit 180 disposed between the portal frame 160 and the housing 110. The limiting unit 180 includes two relatively adjustable limiting rods 181. The limiting rods 181 are disposed across the housing 110 and are detachably connected to the housing 110. The two limiting rods 181 are snapped onto the side of the portal frame 160. The distance between the two limiting rods 181 can be relatively adjusted to adapt to the column and achieve the purpose of limiting constraint.
[0063] In practical implementation, the limiting rod 181 refers to a rigid support structure spanning the housing 110. It can be implemented using a metal rod with a rectangular or circular cross-section, and is constrained to the portal frame 160 via locking parts at both ends. The distance between the two limiting rods 181 can be adjusted according to the dimensions of the housing 110, specifically through a threaded adjustment mechanism or a sliding groove structure. The detachable connection means that the limiting rod 181 is fixed to the housing 110 using bolts or pins, facilitating disassembly and maintenance.
[0064] Specifically, when the housing 110 shifts laterally during lifting, the limiting rod 181 spanning the housing 110 restricts the swing amplitude of the housing 110 by engaging with the side of the portal frame 160. The distance between the two limiting rods 181 can be adjusted according to the width of the housing 110, for example, by adjusting the length of the threaded rod or the position of the sliding groove, so that the limiting rods 181 always fit against both sides of the housing 110. During disassembly, the limiting rods 181 can be separated from the housing 110 by releasing the bolts or pins, facilitating cleaning or replacement of parts.
[0065] Traditional eel sorting systems typically employ fixed limiting structures, which cannot accommodate cages 110 of different sizes and are difficult to disassemble and maintain. This solution, through adjustable-spacing limiting rods 181 and a detachable connection method, achieves compatibility with cages 110 of different specifications while simplifying the equipment maintenance process.
[0066] In some embodiments, please refer to Figure 7The limit rod 181 is equipped with rollers 182 at both ends. The rollers 182 are rolledly connected to the side of the gantry frame 160. The rollers 182 are in direct contact with the column, which can reduce the friction between the rollers 182 and the column, and reduce noise and frictional resistance.
[0067] In practical implementation, roller 182 refers to a rotatable component installed at the end of the limiting rod 181. It can be implemented using a combination structure of bearing and metal hub, and its outer edge can be wrapped with nylon or rubber to reduce noise. This structure reduces the movement resistance between the limiting rod 181 and the portal frame 160 by replacing sliding friction with rolling contact.
[0068] Among them, rolling connection refers to the mechanical relationship in which the roller 182 and the side wall of the portal frame 160 form point contact or line contact, which can be achieved by setting guide rail grooves on the inner side of the portal frame 160.
[0069] Specifically, when the box 110 moves vertically along the portal frame 160 under the drive of the lifting and weighing unit 170, the limiting rod 181 maintains rolling contact with the side wall of the portal frame 160 through the rollers 182 at both ends. The rollers 182 continue to rotate under the constraint of the side wall of the portal frame 160, converting traditional sliding friction into rolling friction.
[0070] In some embodiments, the temporary holding tank 200 includes a tank body 210 for storing eels and a tieable net bag 220. The two ends of the net bag 220 can be connected to the tank body 210 and the box 110 that is moved to a lower position, respectively. The net bag 220 connects the tank body 210 and the box 110, allowing the eels to be fed into the box 110, thus simplifying the eel transfer process.
[0071] The pool 210 is a container for temporarily storing eels to be sorted. It can be implemented using a breeding pool with a circulating water system, and a drain can be installed at the bottom to control the water level. The tieable net bag 220 refers to a conveying channel made of flexible mesh material. It can be implemented using a woven net structure with tie straps at both ends. The flow speed of the eels can be controlled by adjusting the tightness of the tie straps.
[0072] Specifically, when the container 110 moves to its lowest position, one end of the net bag 220 is sealed to the outlet of the fish pond via a tightening strap, and the other end is sealed to the inlet of the container 110 via another tightening strap. After the eels enter the net bag 220 from the fish pond, the flow rate of the eels during transportation can be slowed down by adjusting the tightness of the tightening straps at both ends. Once the container 110 is fully loaded, the connection between the net bag 220 and the container 110 can be separated by untying the tightening straps.
[0073] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the present utility model.
