[0065] Example 1

[0066] Reference Figures 1-12 A device for slaughtering eels, comprising:

[0067] The shell 1 is used for structural protection. A feeding trough 4 is fixed to the top of one end of the shell 1 for placing the eels to be slaughtered inside the feeding trough 4. A discharge pipe 5 is fixed inside the shell 1 at the bottom of the feeding trough 4 and away from the feeding trough 4 for discharging the slaughtered eels into the outer frame.

[0068] The observation door 2 is slidably connected to one side of the housing 1 and is used to observe the inside of the housing 1. It can be opened halfway or fully to observe the eels being processed inside the housing 1.

[0069] Preferably, a cover plate 3 is slidably connected to the top of the shell 1, so that the top of the shell 1 can be closed by the cover plate 3 to prevent water or dirt from splashing onto the outside of the shell 1 during the processing of eels.

[0070] The support frame 6 is bolted inside the housing 1 and is used to support the contour-following acceleration feeding mechanism 12, the cutting and decontamination linkage mechanism 13, and the segmentation mechanism 14, etc.

[0071] Preferably, a control box 9 is fixed inside one side of the housing 1 for providing power to the electrical appliances or equipment in this embodiment, and a step-down module 10 is fixed inside one side of the housing 1 for regulating the power of the control box 9.

[0072] In this embodiment, a box is provided inside the shell 1 and at the bottom of the support frame 6 for collecting the internal organs of the slaughtered eel.

[0073] The contour-following accelerating feeding mechanism 12 is used to transport the eels to be slaughtered;

[0074] The contour-following accelerated feeding mechanism 12 includes:

[0075] The conveying base plate 15 is bolted to the top of the support frame 6 and is used to support the bottom of the conveyed eel. A first rectangular groove 30 is opened in the middle of the conveying base plate 15. A shuttle-shaped abdominal expansion guide 31 is fixed at the top of the conveying base plate 15 and at the end of the first rectangular groove 30 away from the feed water tank 4. The shuttle-shaped abdominal expansion guide 31 is used to enlarge the wound of the opened eel through its shuttle shape. A second rectangular groove 32 is opened inside the shuttle-shaped abdominal expansion guide 31. The cleaning brush 45 located inside the second rectangular groove 32 rotates to clean the inside of the opened eel.

[0076] In this embodiment, the conveying base plate 15 is formed by splicing multiple base plates, and two adjacent base plates are spliced ​​together to form a whole through interference fit of connecting columns.

[0077] The first flexible brush 16 is rotatably connected to both sides of the top of the conveying base plate 15, so that when the eel is conveyed on the top of the conveying base plate 15, the movement of the eel can be restricted by the rotation of the first flexible brush 16 and the adjustment of the soft bristles on the outside of the first flexible brush 16.

[0078] The conveying assembly 17 is disposed at one end of the top of the conveying base plate 15 and is used to continuously convey the eel on the top of the conveying base plate 15.

[0079] Conveying assembly 17 includes:

[0080] The first drive shaft 21 is rotatably connected to the top of the support frame 6 at the end away from the feed trough 4. A second sprocket 22 is fixed on the outer side of one side of the first drive shaft 21, and a third sprocket 23 is fixed on the outer side of the first drive shaft 21 away from the second sprocket 22.

[0081] The second drive shaft 24 is rotatably connected to the top of the support frame 6 near the feed trough 4. A fourth sprocket 25 is fixed on the outside of the second drive shaft 24. The fourth sprocket 25 is connected to the third sprocket 23 by a chain, so that the rotation of the first drive shaft 21 drives the fourth sprocket 25 through the third sprocket 23 and the outer chain, which in turn drives the second drive shaft 24 to rotate. A first drive gear 26 is fixed on the side of the second drive shaft 24 away from the fourth sprocket 25, so that the rotation of the fourth sprocket 25 drives the first drive gear 26 to rotate synchronously through the second drive shaft 24.

[0082] Preferably, a support plate 27 is bolted to the top of the support frame 6 and located between the first drive shaft 21 and the second drive shaft 24. A third drive shaft 28 is rotatably connected inside the support plate 27. A tension sprocket 29 is fixed to the outside of the third drive shaft 28 for adjusting the tension of the sprockets on the outside of the third sprocket 23 and the fourth sprocket 25, so as to prevent the sprockets on the outside of the third sprocket 23 and the fourth sprocket 25 from loosening and causing transmission failure.

[0083] The limiting component 18 is set on the top of the conveying component 17 near the feeding trough 4 and is used to squeeze and convey the eels fed through the feeding trough 4.

[0084] Limiting component 18 includes:

[0085] The second flexible brush 33 is rotatably connected to both sides of the top of the conveying base plate 15 near the end of the feeding water tank 4, and is used to limit and squeeze the eel conveyed through the feeding water pipe 11.

[0086] The fourth drive shaft 34 is rotatably connected to the second flexible brush 33 at the top of the support frame 6 near the end of the feed trough 4. A contouring acceleration wheel 35 is fixed on the outside of the fourth drive shaft 34 for contouring and extruding the eel that is transported from the feed pipe 11 to the top of the conveying base plate 15.

[0087] The second transmission gear 36 is fixed on the outer side of the fourth transmission shaft 34. The second transmission gear 36 is meshed with the third transmission gear 37 on the side close to the first transmission gear 26. The third transmission gear 37 is rotatably connected to the support frame 6 and meshes with the first transmission gear 26. Thus, the rotation of the first transmission gear 26 can drive the fourth transmission shaft 34 to rotate through the meshing of the third transmission gear 37 and the contouring acceleration wheel 35. This allows the contouring acceleration wheel 35 to transport the eel squeezed at the bottom while the chain on the outer side of the third sprocket 23 and the fourth sprocket 25 contacts and squeezes to continue transporting the eel.

[0088] Preferably, an AC motor 19 is fixed at the bottom inside the housing 1. The output end of the AC motor 19 is connected to a first sprocket 20. The first sprocket 20 and the second sprocket 22 are driven by a chain. Thus, when the contouring acceleration feeding mechanism 12 is working, the AC motor 19 is used as the driving source. The chain outside the first sprocket 20 drives the second sprocket 22 to drive the first transmission shaft 21 to rotate and transmit power.

[0089] Preferably, a feed pipe 11 is fixed to one end of the conveying base plate 15 near the feed tank 4, and the other end of the feed pipe 11 away from the conveying base plate 15 is located at the bottom inside the feed tank 4, so that the eels inside the feed tank 4 can swim to the top of the conveying base plate 15 through the feed pipe 11.

[0090] A cleaning component is fixed to one side of the support frame 6 and at the top of the contour-following acceleration feeding mechanism 12. The cleaning component includes:

[0091] The bamboo-joint tube 7 is fixed to the top of one side of the support frame 6 and is used to rinse the designated area by bending the bamboo-joint tube 7.

[0092] Water pump 8, fixed to the top of support frame 6, is used to deliver external water into the interior of bamboo tube 7 and spray it out.

[0093] The gutting and cleaning linkage mechanism 13 is used to open and clean the eels conveyed by the contour-following and accelerating feeding mechanism 12.

[0094] The dissection and decontamination linkage mechanism 13 includes:

[0095] The DC geared motor 38 is bolted to the inside of the support frame 6, so that the DC geared motor 38 is located at the bottom of the conveying base plate 15 on the first flexible brush 16. The output end of the DC geared motor 38 is connected to the fifth drive shaft 39.

[0096] The first circular blade 40 is fixed on the outside of the fifth drive shaft 39 and is located inside the first rectangular groove 30, so that the top of the first circular blade 40 can extend out of the first rectangular groove 30 and be located on the top of the conveying base plate 15 to open the belly of the eel conveyed on the conveying base plate 15.

[0097] The sixth drive shaft 44 is rotatably connected to one end of the fifth drive shaft 39 inside the support frame 6. A cleaning brush 45 is fixed on the outside of the sixth drive shaft 44. The cleaning brush 45 is located inside the second rectangular groove 32 and is used to rotate and clean the abdomen through the fusiform abdominal expansion guide 31, thereby allowing the internal organs of the eel to be removed.

[0098] A transmission component is installed between the first toothed gear 41 and the sixth transmission shaft 44 to allow the rotation of the fifth transmission shaft 39 to drive the sixth transmission shaft 44 to rotate synchronously.

[0099] The transmission components include:

[0100] The first toothed gear 41 is fixed on the outside of the fifth transmission shaft 39;

[0101] The second toothed wheel 42 is fixed on the outside of the sixth transmission shaft 44. The second toothed wheel 42 is connected to the first toothed wheel 41 through a synchronous toothed connection. At the same time, the diameter of the first toothed wheel 41 is smaller than the diameter of the second toothed wheel 42, so that the rotation of the fifth transmission shaft 39 causes the first toothed wheel 41 to drive the second toothed wheel 42 to rotate at a reduced speed through the synchronous toothed belt on the outside.

[0102] Preferably, a tensioning wheel 43 is rotatably connected to the inner side of the support frame 6 and located between the fifth drive shaft 39 and the sixth drive shaft 44, for adjusting the tension of the synchronous toothed belt on the outer side of the first toothed wheel 41 and the second toothed wheel 42.

[0103] The segmenting mechanism 14 is used to segment the gutted eel and send the segmented eel out through the discharge pipe 5;

[0104] The cutting mechanism 14 includes:

[0105] The pipe 46 is cut and fixed to the end of the conveyor base plate 15 away from the feed tank 4, so as to allow the cleaned eels to be output.

[0106] The fixing plate 47 is fixed to the end of the support frame 6 away from the feed water tank 4. The fixing plate 47 is bolted to the end of the support frame 6. The inner side of the fixing frame is slidably connected to the slide table 49.

[0107] Preferably, a closed-loop stepper motor 48 is fixed at the top of the fixed frame, and a threaded post is connected to the output end of the closed-loop stepper motor 48. The outer side of the threaded post is threadedly connected to the slide table 49, so that the operation of the closed-loop stepper motor 48 can drive the slide table 49 to adjust its height inside the fixed frame.

[0108] A DC motor 50 is fixed on one side of the slide table 49. The output end of the DC motor 50 is connected to a second circular blade 51, which is used to cut the cleaned eel at the output end of the cutting pipe 46 into sections by the lifting and lowering of the slide table 49 and the rotation of the second circular blade 51.

[0109] Preferably, a first photoelectric gate sensor 52 is fixed on the top of the conveying base plate 15 and at the end of the contouring acceleration wheel 35 near the feeding water tank 4, and a second photoelectric gate sensor 53 is fixed on the outer side of the cutting pipe 46 away from the contouring acceleration feeding mechanism 12. Thus, through the dual detection of the first photoelectric gate sensor 52 and the second photoelectric gate sensor 53, it is determined that the eel will be opened and cleaned after being conveyed. Then, the closed-loop stepper motor 48 and the DC motor 50 are controlled by the step-down module 10 to cut the eel.

[0110] In this embodiment, each structure has its own service life. In actual manufacturing and application, the corresponding structure made of different materials can be replaced according to the needs of use.

[0111] In this embodiment, the motor is a self-locking motor, which can drive the connected structure to rotate normally when it is powered on and working. When the motor stops working, it can prevent the connected structure from rotating through its self-locking function.

[0112] The process of using the eel slaughtering device provided by the present invention is as follows: When in use, the eel to be slaughtered is placed inside the feeding tank 4. During operation, the eel is allowed to enter through the feeding pipe 11 connected to the feeding tank 4. After being output through the feeding pipe 11, it is recorded for the first time by the first photoelectric gate sensor 52. Then, the eel is conveyed by the working of the contour-following acceleration feeding mechanism 12.

[0113] When the contour-following acceleration feeding mechanism 12 is working, the AC motor 19 drives the first sprocket 20 and the outer chain to rotate the second sprocket 22. The second sprocket 22 drives the first drive shaft 21 to rotate, which in turn drives the third sprocket 23. The rotation of the third sprocket 23 drives the outer sprocket to rotate the fourth sprocket 25. At this time, the height can be adjusted by connecting the support plate 27 to the support frame 6, allowing the third drive shaft 28 to drive the tension sprocket 29 to adjust the height, thereby adjusting the tension of the chain on the outer sides of the third sprocket 23 and the fourth sprocket 25. The rotation of the second drive shaft 24 drives the first drive gear 26 to rotate, causing the first drive gear to rotate. The rotation of wheel 26 drives the rotation of the second transmission gear 36 through the meshing third transmission gear 37. The rotation of the second transmission gear 36 drives the rotation of the contouring acceleration wheel 35 through the fourth transmission shaft 34. This causes the eel, which is located at the top of the conveying base plate 15 and is conveyed through the feed water pipe 11, to be squeezed on the head by the rotation of the contouring acceleration wheel 35. It then enters the bottom of the fourth sprocket 25 through the flexible contact of the two second flexible brushes 33. Then, the chain on the outside of the fourth sprocket 25 and the third sprocket 23 rotates to squeeze and push the back of the eel, allowing the eel to be continuously conveyed forward on the top of the conveying base plate 15. Finally, the abdomen is opened and cleaned by the operation of the dissection and evisceration linkage mechanism 13.

[0114] When the cutting and gutting linkage mechanism 13 is working, the operation of the DC geared motor 38 drives the fifth transmission shaft 39 to rotate, which in turn drives the first circular blade 40 to rotate. The top of the first circular blade 40 extends out of the first rectangular groove 30, opening the abdomen of the eel conveyed on the top of the conveying base plate 15. The eel, which continues to move forward, passes through the shuttle-shaped abdominal expansion guide 31 to enlarge the opening. At the same time, the rotation of the fifth transmission shaft 39 drives the first toothed wheel 41 to rotate. The rotation of the first toothed wheel 41 drives the second toothed wheel 42 to rotate through the external synchronous toothed belt. The second toothed wheel 42 drives the cleaning brush 45 to rotate through the sixth transmission shaft 44. The cleaning brush 45, located inside the second rectangular groove 32, rotates slowly to clean the eel whose opening has been enlarged by the shuttle-shaped abdominal expansion guide 31, and allows the internal organs to be collected in the box at the bottom of the shell 1.

[0115] Then, the gutted eels are allowed to enter the cutting pipe 46, and the second photoelectric gate sensor 53 performs a second detection. At this time, the operation of the closed-loop stepper motor 48 drives the slide table 49 to rise and fall, while the rotation of the DC motor 50 drives the second circular blade 51 to rotate, thereby cutting the gutted eels discharged from the cutting pipe 46 into sections, and then transporting them to the outer frame through the discharge pipe 5 after cutting.

[0116] Simultaneously, the detection by the first photoelectric gate sensor 52 and the secondary detection by the second photoelectric gate sensor 53 cause the control box 9 to control the water pump 8 to work, so that the water pump 8 can transport external water into the interior of the bamboo tube 7, and rinse the position of the limiting component 18 and the top of the conveying base plate 15 through the bamboo tube 7.

[0117] Example 2

[0118] Based on the above embodiment one, a Unity virtual platform is disclosed for controlling the structure in embodiment one, in order to solve the pain points of traditional agricultural machinery "black box operation" and lack of safety monitoring;

[0119] First, at the top of the platform is the conveying assembly 17, next to which is the first flexible brush 16 on the conveying base plate 15. At the tail of the conveying base plate 15, a cutting and cleaning linkage mechanism 13 is set to realize the opening of the abdomen and cleaning of the entrails of the eel. A chain is placed on the right side of the platform to connect to the AC motor 19 below. On the far right is a cutting pipe 46 to provide the eel with a way to slide out to the water tank at the bottom. A cutting mechanism 14 is placed on the upper part of the channel. These modules together constitute the Unity virtual platform.

[0120] The microcontroller inside the control box 9 receives data from the Unity virtual platform, allowing it to synchronize with the real machine on the screen. A local 5G communication network is established using BW16, enabling a remote, low-latency synchronous connection between the microcontroller and the Unity software on the computer. The microcontroller processes and outputs data, while the Unity host computer on the computer receives the data wirelessly via TCP / IP. The microcontroller sends coordinate data packets and digital twin synchronization commands to Unity at a fixed frequency, completing real-time closed-loop monitoring of the digital twin.

[0121] To accurately capture every dynamic detail inside the machine, two photoelectric gate sensors (first photoelectric gate sensor 52 and second photoelectric gate sensor 53) are used to provide a stable data source for the digital twin. The photoelectric gate sensors primarily perform two tasks: first, real-time monitoring of the material feeding and discharging status; and second, stable sampling at fixed intervals. By fusing multi-dimensional sensor data, the system achieves real-time statistics on the number of animals slaughtered, and the processed data is pushed to the host computer in real time, realizing full-process digital monitoring.

[0122] Digital twin serial port commands are shown in Table 1:

[0123] Table 1: Digital Twin Serial Port Command Table

[0124]

[0125] When the eel slaughtering equipment in Example 1 is working:

[0126] When Unity receives the "!1%" signal, the system activates the conveyor component 17, thereby activating the global system operation. In the Unity scene, the chain and transmission components move at a preset speed. Simultaneously, the status indicator light of the transmission module in the interactive interface changes from red to green, the button status updates to "On," and the transmission dashboard UI begins to dynamically fill and display the chain speed in real time. If the Unity system receives the "!0%" signal, the eel model stops moving, the corresponding UI indicator light status returns to normal, and the dashboard data resets to zero. In the cutting and processing stage, when the system receives the "$S#" signal, the cutting and cleaning linkage mechanism 13 starts, and the motor dashboard in the UI dynamically displays the rotation speed. When the system receives the "$C#" shutdown signal, the rotation of the corresponding mechanism and the UI highlight immediately stop.

[0127] The system uses the movement trajectory of an eel to simulate movement. When it receives the feeding start signal "@1&" and detects that both the transmission and cutting modules are in the on state, it will activate the virtual eel model. By monitoring the no-load and load current of the motor, the system monitors the working status of the machine and thus simulates the position display of the eel. When it receives the processing end or discharge signal "@0&", it will synchronously trigger the movement of the tail cutting mechanism 14 of the eel slaughtering machine. After the cutting mechanism 14 is started, it will simultaneously monitor the real-time position of the slide table 49 and the second circular blade 51. The system receives the data uploaded by the main control and prints it in the upper computer log ($position distance#) to monitor the cutting task progress in real time.

[0128] The system also features a UI platform for interactive functionality, allowing users to control the physical equipment by clicking UI buttons. Pressing a button on a specific module sends a command to the main controller to operate the slaughtering machine, while the main controller simultaneously sends a command back to the host computer to change the state of the corresponding UI module component. To address potential emergencies during mechanical control, the system is equipped with a high-priority emergency stop protection mechanism. Whether triggered by a physical emergency stop button on the hardware and sending a "!!!" signal to Unity, or by an operator clicking a virtual emergency stop button on the interface and sending a "!!!" command to the host computer, the system will immediately enter a global freeze and emergency stop lock state upon receiving the emergency signal. All transmission chains, circular blades, brushes, and related structures in the Unity scene will be forcibly stopped, and the eel slaughtering machine will also be forced to cease all operations. This safety mechanism ensures that both the virtual environment and the physical equipment remain absolutely still until a fault is manually detected.

[0129] The above commands “!1%”, “!0%”, “$S#”, “$C#”, “@0&”, $25.00#, and “!!!” all take values ​​from the range in Table 1. Please refer to Table 1 for details.

[0130] Traditional equipment monitoring is only a one-way process of "looking at data and status," while digital twins are a two-way process of "monitoring + interaction + simulation"—not only can you see the status of real equipment, but you can also conduct simulation tests on the virtual end, and then feed the optimization solutions back into the real equipment to promote the optimization and upgrading of the equipment.

[0131] To verify whether the "eel slaughtering equipment" can efficiently and safely slaughter eels, data such as processing efficiency and evisceration rate were collected from a farmers' market after skilled workers operated continuously for 30 minutes. Subsequently, 50 live eels of similar size and length were selected for a live-machine slaughtering test. The specific comparison results of various performance indicators after the test are shown in Table 2.

[0132] Table 2: Test Data Comparison Table

[0133]

[0134] Experimental data shows that this slaughtering equipment has a greater slaughtering efficiency and success rate than manual slaughtering, and it is basically ready to be put into production in pre-made vegetable factories and farmers' markets, with a very broad application prospect.
