[0014] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0015] Please see Figure 1-5 A sorting device for eels includes a lifting and conveying mechanism 1. Two sorting mechanisms 2 are provided at the end of the lifting and conveying mechanism 1. A guide platform 7 is provided at the end of the sorting mechanism 2. An installation plate 8 is provided on the guide platform 7. A middle collection frame 9 is slidably connected to the top of the installation plate 8. A support frame 3 is provided to the right of the guide platform 7. A last collection frame 4 is slidably connected to the top of the support frame 3. The horizontal height of the last collection frame 4 is lower than the horizontal height of the guide platform 7. A controller 6 is fixed to the surface of the support frame 3.

[0016] Through the above technical solution, the lifting and conveying mechanism 1 is responsible for lifting the eels located at a low position to a certain height, providing the necessary gravitational potential energy for the subsequent sorting process. After the eels are conveyed to the right side from the lifting and conveying mechanism 1, they are first sorted at the sorting mechanism 2. Eels that meet the specific weight standard will be sorted out, while eels that do not meet the standard will continue to slide to the right. The guide platform 7, as a transfer platform, receives the eels from the left sorting mechanism 2 and guides them to the middle collection box 9 for collection through the mounting plate 8 on its surface. The support frame 3 and the last collection box 4 on it are located at the very end of the entire device, and its top height is lower than the top height of the guide platform 7. This allows the eels sliding down from the guide platform 7 to fall smoothly and steadily into the last collection box 4 using the height difference, thereby achieving the collection of all eels without omission. The controller 6 coordinates and controls the timing and logic of a series of actions such as lifting, conveying, weighing and diverting, ensuring that the sorting process is automated and continuous.

[0017] The sorting mechanism 2 includes a support leg 201 and a diversion platform 205. A conveyor plate 202 is fixed to the top of the support leg 201, and a holding plate 203 is welded to the middle of the support leg 201. A diversion collection frame 204 is slidably connected to the surface of the holding plate 203. A pressure sensor 206 is fixed to the top of the diversion platform 205, and a weighing plate 207 is fixed to the top of the pressure sensor 206. The diversion platform 205 is located on the right side of the support leg 201. An extension block 208 is hinged to the top right side of the diversion platform 205, and a diversion plate 209 is fixed to the top of the extension block 208. A cylinder 210 is hinged to the bottom right side of the diversion plate 209, and the other end of the cylinder 210 is hinged to the middle right side of the diversion platform 205. The conveyor plate 202, the guide platform 7, the weighing plate 207, and the diversion plate 209 are all designed with an angled structure that is higher on the left and lower on the right.

[0018] Through the above technical solution, the conveyor plate 202 smoothly conveys the eel, which is tilted at an appropriate angle, onto the weighing plate 207. The pressure sensor 206 connected below the weighing plate 207 immediately and accurately senses the weight of the eel and converts the weight data into an electrical signal, which is transmitted to the controller 6. The controller 6 judges according to the preset weight grading standard and quickly issues a command to control the extension and retraction of the cylinder 210. The pushing and pulling of the cylinder 210 drives the diverter plate 209 to rotate upward or downward around its hinge point with the extension block 208, thereby moving... The outlet direction at the end of the diversion plate 209 is changed. When the eel slides out of the weighing plate 207, it will be guided to different paths according to the current angle of the diversion plate 209. It may fall into the diversion collection box 204 below, or continue to slide to the next processing stage on the right. The conveyor plate 202, guide table 7, weighing plate 207 and diversion plate 209 all adopt a tilted structure with the left side higher than the right side. This design ensures that the eel can slide smoothly by its own gravity throughout the sorting process without external pushing. The movement process is natural and smooth.

[0019] The lifting and conveying mechanism 1 includes a frame 101, which has an inclined structure with the left side lower than the right side. Two conveying rollers 102 are rotatably connected to the surface of the frame 101. A conveyor belt 103 is provided on the surface of the two conveying rollers 102. Multiple equally spaced partitions 104 are fixed on the surface of the conveyor belt 103. A drive motor 109 is fixed on the surface of the frame 101. The output shaft of the drive motor 109 passes through the frame 101 and is fixedly connected to the surface of one of the conveying rollers 102.

[0020] Through the above technical solution, the frame 101 adopts an inclined structure design with the left side lower and the right side higher, which provides a basic inclined surface for the upward conveying of eels. After the drive motor 109 starts, it drives the conveyor roller 102 on one side to rotate through the output shaft, which in turn drives the conveyor belt 103 sleeved on the two conveyor rollers 102 to rotate in a cycle. Multiple equidistant partitions 104 fixed on the surface of the conveyor belt 103 can effectively "catch" the eels when passing through the bottom feeding area as the conveyor belt 103 moves, forming independent carrying units. The presence of these partitions 104 prevents the eels from sliding down due to gravity during the inclined upward process, ensuring that each eel can be stably and reliably lifted to the unloading point at the top of the device, thus preparing for the subsequent sorting process.

[0021] Side baffles 105 are fixed on both the front and rear sides of the top of the frame 101. A guide plate 107 is fixed on the left side surface of the side baffle 105. A feeding port 106 is provided above the guide plate 107 and a feeding port 108 is provided below the guide plate 107. An L-shaped baffle 111 is fixed between the front and rear side baffles 105. The L-shaped baffle 111 is located above the conveyor belt 103.

[0022] Through the above technical solution, the side baffles 105 are fixed to the front and rear sides of the top of the frame 101, forming the physical boundary of the conveying channel, effectively preventing the eels from accidentally falling off the front and rear sides of the conveyor belt 103 during the conveying process. The feeding port 106 is the entrance for manual or upstream equipment to feed the eels. The guide plate 107 extends from the left side surface of the side baffles 105. Its function is to smoothly guide the eels fed from the feeding port 106 to the feed port 108 below, ensuring that the eels can accurately enter the effective working area of ​​the conveyor belt 103. When the conveyor belt 103 carries the eels upward, the L-shaped baffle 111 is located above the eel's body. Its core function is to prevent the eels from twisting their bodies and jumping upward or rolling backward from the unit formed by the partition 104 during the lifting process, ensuring that each eel is confined in the designated compartment until it is transported to the highest point.

[0023] A support plate 110 is fixed to the surface of the frame 101. The support plate 110 is located inside the conveyor belt 103, and the top of the support plate 110 is slidably connected to the surface of the conveyor belt 103.

[0024] With the above technical solution, when the conveyor belt 103 is running in a cycle driven by the conveyor roller 102, the section of the belt that carries the eel upwards is laid flat on the surface of the support plate 110. The support plate 110 provides continuous and solid physical support for this section of the conveyor belt 103, so that even if the conveyor belt 103 bears the weight of the eel and the partition 104, there will be no obvious sinking or deformation in the middle section.

[0025] Anti-detachment plates 211 are fixed on the front and rear sides of the top of the conveyor plate 202, guide platform 7, weighing plate 207 and diverter plate 209.

[0026] Through the above technical solution, the anti-detachment plate 211 forms a continuous protective barrier on both sides of these paths. When the eel slides at high speed on these inclined plates due to gravity, its movement trajectory may be uncertain due to its smooth body surface and irregular shape, and there is a risk of it sliding off the side. The anti-detachment plate 211 acts as a physical barrier to promptly block any eel that may deviate to the side, forcing it to slide forward along the preset correct path until it reaches its destination.

[0027] The support leg 201, the guide platform 7, and the support frame 3 are all fixed with baffle plates 5.

[0028] With the above technical solution, during the sorting process, when the eel falls into the collection box at a certain speed, the collection box itself may move unexpectedly. The presence of the baffle plate 5 physically limits the range of movement of the collection box.

[0029] Working principle: The operator feeds the eels to be sorted through the feeding port 106. Guided by the guide plate 107, the eels enter the running conveyor belt 103 area through the feeding port 108 and are captured and separated by the equally spaced baffles 104. Under the combined constraint of the side baffles 105 and the upper L-shaped baffle 111, the eels are safely and reliably lifted to the highest point of the device. During this process, the conveyor belt 103 is powered by the drive motor 109 and stably supported by the inner support plate 110. After reaching the top, the eels slide out under gravity and fall into the leftmost sorting mechanism 2. The eels first slide onto the conveyor plate 202 of the sorting mechanism 2. This plate, as well as the weighing plate 207 and the diverting plate 209 behind it, are all designed with a left-high and right-low tilt to ensure that the eels can slide automatically. During the sliding process, the anti-detachment plates 211 on both sides of all the plates ensure that the eels move along the correct path and do not slide sideways. When an eel passes the weighing plate 207, the pressure sensor 206 below it accurately senses the eel's weight and transmits the signal to the controller 6. The controller 6, based on preset weight logic, immediately controls the cylinder 210 to rotate the diverting plate 209, guiding the eel to the corresponding diverting collection box 204 for initial sorting. Eels that fail to be sorted continue sliding to the second sorting mechanism 2 and eventually to the guide platform 7. The guide platform 7 receives the eels from the left sorting mechanism 2 and guides them to the middle collection box 9 for collection, or allows them to continue sliding. Finally, the remaining eels slide out from the guide platform 7 and, utilizing the height difference with the last collection box 4, fall smoothly into the last collection box 4. Thus, the eel completes the entire automated sorting process from lifting, conveying, weighing, diverting to multi-stage collection. This achieves efficient, accurate, and low-damage eel sorting, effectively solving the problems of low efficiency and inconsistent standards in traditional manual sorting.
