[0038] The following Figures 1-4 introduces an automatic fish-killing machine provided by an embodiment of the present application, which includes a main body frame 1. A fish catch drawer 2 that can be pulled out, a descaling device 3, a cleaning device 4, and a control device 5 are provided inside the main body frame 1.

[0039] A fixing and detecting device 6 is provided inside the fish catch drawer 2. The fixing and detecting device 6 is used to fix the fish, automatically adjust the fixing position according to the size of the fish, and detect the attribute parameters of the fish. The attribute parameters at least include the type, posture, or size parameters of the fish.

[0040] The descaling device 3 is used to adjust the scale scraping structure 311 according to the attribute parameters of the fish and perform a descaling operation on the fish.

[0041] The cleaning device 4 is used to rinse the descaled fish to remove residues.

[0042] The cleaning detection mechanism 40 is used to detect the cleanliness parameter of the fish surface. The cleanliness parameter characterizes the fish scale removal situation.

[0043] The control device 5 is electrically connected to the fixing and detecting device 6, the descaling device 3, the cleaning device 4, and the cleaning detection mechanism 40. The control device 5 is used to control the descaling device 3 and the cleaning device 4 to perform descaling and cleaning operations according to the attribute parameters and the cleanliness parameter, and judge whether to perform a secondary descaling operation according to the cleanliness parameter of the fish surface after cleaning is completed.

[0044] In the fish-killing process of this automatic fish-killing machine, the fish is placed in the fish catch drawer 2 that can be pulled out inside the main body frame 1. The fish is fixed by the fixing and detecting device 6, and the fixing position is adjusted according to the size of the fish to ensure that the fish is stable and does not move. At the same time, the attribute information such as the type, posture, and size parameters of the fish is detected and identified. The detected attribute parameters are transmitted to the control device 5. After receiving the attribute parameters, the control device 5 adjusts the scale scraping structure 311 in the descaling device 3 to a suitable working state according to the type, posture, and size of the fish. The descaling device 3 is controlled to perform a descaling operation on the fish to ensure that the scale scraping force is moderate and the fish meat is not damaged. The descaled fish is comprehensively rinsed by the cleaning device 4 to remove the remaining scales and other dirt. After cleaning is completed, the cleanliness parameter of the fish surface is detected, and the detected cleanliness parameter is transmitted to the control device 5. The control device 5 judges whether secondary descaling is required according to the cleanliness parameter. If the cleanliness parameter is greater than the preset cleanliness threshold and the cleanliness does not meet the standard, the descaling device 3 is controlled to perform a secondary descaling operation; if the cleanliness meets the standard, this step is skipped. After all operations are completed, the control device 5 sends a signal to prompt the operator to pull out the fish catch drawer 2 and take out the processed fish.

[0045] The cleanliness threshold of this embodiment is the fish surface cleanliness value when the descaling condition of the fish meets the preset standard. The larger the fish surface cleanliness parameter is, the worse the current descaling condition of the fish is.

[0046] In this embodiment, the entire fish-killing process realizes a high degree of automation, reduces manual intervention, and improves the processing efficiency. The fixing and detecting device can automatically adjust the fixing position according to the size of the fish, and the descaling device can also adjust the scale-scraping structure according to the type and size of the fish to ensure consistent processing effects. The control device can intelligently adjust the descaling device 3 and the cleaning device 4 according to the real-time detected data, realizing precise control and improving the processing efficiency and descaling quality.

[0047] Further, the fixing and detecting device 6 includes a fixing device 61 and a first detecting mechanism. The fixing device 61 includes an elastic reset structure 611, and the elastic reset structure 611 is used to connect with the tail of the fish; a first detecting mechanism is arranged on the elastic reset structure 611 for real-time detection of attribute parameters.

[0048] Specifically, the fixing device 61 further includes a fish head fixing structure 612. The fish head fixing structure 612 is arranged at one end of the fish catch drawer 2 away from the elastic reset structure 611 for fixing the fish head or the gill part. In a possible implementation manner, the fish head fixing structure 612 is a group of adjustable clamping arms or a puncture fixing structure that can pierce the fish head or gills. In a possible implementation manner, the elastic reset structure 611 is a spring-type reset structure. One end of the spring is connected to the inner wall of the fish catch drawer 2, and the other end is used to connect with the fish tail, which can adapt to fish of different sizes. The first detecting mechanism can be a pose sensor arranged on the elastic reset structure 611. Through the pose sensor, the size of the fish fixed in the fish catch drawer 2 can be detected. In a possible implementation manner, the first detecting mechanism can be an image recognition system combined with a pose sensor and a camera, which can accurately identify the type, pose and size of the fish. When the fish-killing machine of this embodiment is in use, it is necessary to first open the fish catch drawer 2, fix the fish in the fish catch drawer 2 through the fixing and detecting device 61, and then close the fish catch drawer 2 before further descaling and cleaning steps. The fish fixing step is simple, ensuring stable fixation of the fish during the processing.

[0049] Further, the cleaning device 4 includes a spraying mechanism. The spraying mechanism includes a connecting pipe 42 and a plurality of spray heads 41. The connecting pipe 42 is communicated with the water inlet of the main body frame 1.

[0050] Specifically, the spraying mechanism is arranged on one side of the main frame 1. The spraying mechanism includes a plurality of spray heads 41. The spray heads 41 are connected to the water inlet of the main frame 1 through connecting pipes 42 to achieve uniform spraying of high-pressure water flow. In a possible implementation manner, the spraying mechanism includes two spray heads 41, which are respectively arranged above and below the fish catch drawer 2 of the fish to wash both sides of the fish simultaneously.

[0051] In a possible implementation manner, the cleaning detection mechanism 40 is a pressure sensor arranged on the descaling device 3, which is used to obtain the cleanliness parameter of the fish surface. The pressure sensor can be attached to the fish body surface. When the fish scales are not completely removed, the pressure sensor will sense the slight pressure difference caused by the raised scales or uneven surface. If the pressure sensor outputs high pressure signals at multiple positions on the fish body surface, it indicates that the fish scales are not thoroughly removed and further processing is required. If the electrical signals output by the pressure sensor are relatively uniform and lower than the set threshold, it indicates that the scales on the fish body surface have been basically removed and meet the expected cleanliness requirements. In another possible implementation manner, the cleaning detection mechanism 40 can also be set as a device that combines a camera and a pressure sensor to obtain the cleanliness parameter of the fish surface. In this embodiment, the cleaning detection mechanism 40 can obtain the cleanliness parameter of the fish surface to determine the descaling condition of the fish.

[0052] Furthermore, the descaling device 3 includes a first descaling assembly 31, a second descaling assembly 32 and corresponding descaling motors 33 respectively arranged on both sides of the fish body. Both the first descaling assembly 31 and the second descaling assembly 32 include a plurality of scale scraping structures 311 arranged at intervals.

[0053] Specifically, the scale scraping structure 311 includes a rotating shaft and a plurality of scraping plates arranged uniformly along the circumferential and axial directions on the rotating shaft. Each scale scraping structure 311 can be controlled by the descaling motor 33 to rotate for scale scraping operations. The first descaling assembly 31 and the second descaling assembly 32 are respectively arranged above and below the fish catch drawer 2 to remove the fish scales on both sides of the fish body after the fish is fixed. In a possible implementation manner, the descaling motor 33 can be a variable-frequency speed-regulating motor. The descaling motor 33 is connected to the rotating shaft through a gear or belt drive system to achieve the rotation of the scale scraping structure. The descaling motor 33 can adjust the speed according to the instructions of the control device 5 to meet the descaling requirements of different fish.

[0054] Furthermore, a garbage drawer 11 is provided inside the main frame 1. The garbage drawer 11 is arranged below the fish catch drawer 2 and is used to collect the garbage and waste generated during the descaling process.

[0055] In this embodiment, the garbage drawer 11 is arranged below the fish catch drawer 2, with a compact structure, facilitating the direct collection of garbage and waste generated during the descaling process. The drawer-type structures of the fish catch drawer 2 and the garbage drawer 11 make the overall structure of the fish killing machine more compact, with good sealing performance, and are convenient for fixing the fish and cleaning the garbage, which is conducive to maintaining environmental cleanliness and hygiene and can adapt to more occasions.

[0056] In another possible implementation, a garbage box 12 is provided inside the main body frame 1. The garbage box 12 is arranged below the descaling device 3 and is used to collect the garbage and waste generated during the descaling process. A water outlet 13 is provided below the garbage box 12, and the water outlet 13 is used to discharge the liquid and wastewater generated during the use of the fish killing machine.

[0057] Furthermore, the control device 5 includes a descaling control module. The descaling control module is used to control the descaling operation of the fish by the corresponding number and interval of the scale scraping structures 311 according to the attribute parameters detected by the first detection mechanism. In this embodiment, the control device 5 will calculate the number of the scale scraping structures 311 suitable for the current fish and the interval of their activation according to the attribute parameters of the fish detected by the first detection mechanism and the preset algorithms and rules. For example, for large fish, more scale scraping structures 311 may need to work simultaneously and maintain a smaller interval; while for small fish, the number of the scale scraping structures 311 may be reduced and the interval may be increased. The control device 5 sends a control signal to the descaling motor 33 to activate the corresponding number and interval of the scale scraping structures 311 for descaling operation. During the scale scraping process, the motor speed can be dynamically adjusted as needed to ensure the best descaling effect.

[0058] In this embodiment, by precisely controlling the number and interval of the scale scraping structures, a personalized descaling scheme can be implemented for fish of different sizes, significantly improving the descaling efficiency. Fast and accurate descaling operations can be achieved without manual adjustment, reducing labor costs and labor intensity. The entire descaling process is highly automated, reducing errors and uncertainties caused by human intervention and improving the stability and reliability of the production line.

[0059] Furthermore, the control device 5 includes a wireless communication module 51. The wireless communication module 51 is used to communicate with a mobile device and / or a computer to remotely control the operation of the fish killing machine.

[0060] Specifically, a wireless communication module 51, such as a Wi-Fi, Bluetooth, or 4G / 5G module, is integrated inside the control device 5, enabling the fish killing machine to establish a communication connection with an external mobile device or computer. The user can send control instructions to the wireless communication module 51 through the mobile device or computer. After the module parses the instructions, the control device 5 performs corresponding operations, such as starting / stopping scaling and adjusting scaling parameters. The user can also view the real-time operating status of the fish killing machine through a remote control APP or web interface on the mobile device or computer, including the number of fish currently being processed, the scaling progress, the cleanliness, etc. In this embodiment, the user can remotely monitor and operate the fish killing machine, improving the flexibility, convenience, and intelligence of using the fish killing machine.

[0061] Further, the control device 5 includes a time prediction module for obtaining the predicted scaling completion time according to the attribute parameters and the preset target parameters after scaling.

[0062] Specifically, the time prediction module predicts the predicted scaling completion time through a time prediction model based on the collected attribute parameters of the fish, such as species, size, weight, etc., and the preset target parameters after scaling, such as the cleanliness standard. In a possible implementation manner, the scaling completion time can be displayed through a remote control APP or a display device arranged on the outer wall of the main body frame 1. In this embodiment, the fish killing machine accurately predicts the predicted scaling completion time, enabling the user to understand the scaling completion time in advance to better arrange subsequent work and enhance the overall user experience.

[0063] The embodiment of the present application also provides a control method for an automated fish killing machine, and the method includes:

[0064] Place the fish to be processed in the fish catch drawer and fix its head and tail through the fixing and detecting device;

[0065] Obtain the attribute parameters of the fish, where the attribute parameters at least include the species, posture, or size information of the fish;

[0066] Based on the attribute parameters, control the scaling structures with corresponding quantity and intervals to perform scaling operations on the fish;

[0067] After the scaling is completed, control the cleaning device to start and clean the fish;

[0068] Obtain the cleanliness parameter of the surface of the fish after cleaning is completed;

[0069] If the cleanliness parameter is greater than the preset cleanliness threshold, control to start the secondary scaling operation.

[0070] Before the secondary descaling operation in this embodiment, the current descaling information of the fish can be obtained, and the current descaling information is the surface cleanliness information of the current fish; according to the current descaling information of the fish, the working parameters of the descaling device are adjusted, such as the number of scale scraping structures, the spacing distance, and the rotational speed of the descaling motor, and based on the adjusted working parameters, the fish killing machine is controlled to descale the fish again.

[0071] The control method of the fish killing machine in this embodiment further includes: predicting the estimated descaling completion time according to the attribute parameters of the fish and the preset target parameters after descaling.

[0072] In a possible implementation manner, the control method of the automatic fish killing machine includes:

[0074] Obtain the attribute parameters of the fish, and the attribute parameters at least include the type, posture or size information of the fish;

[0075] Predict the estimated descaling completion time according to the attribute parameters of the fish and the preset target parameters after descaling, and display the estimated descaling completion time through the display device and / or the remote control APP;

[0076] Based on the attribute parameters, control the scale scraping structures with corresponding quantity and spacing to perform descaling operation on the fish;

[0077] After the first descaling is completed, control the cleaning device to start and clean the fish;

[0078] Obtain the cleanliness parameter of the fish surface after cleaning is completed;

[0079] If the cleanliness parameter is greater than the preset cleanliness threshold, control to start the secondary descaling operation and update the descaling completion time in real time.

[0080] The entire fish killing process in this embodiment realizes a high degree of automation, reduces manual intervention, and improves the processing efficiency. The fixing and detecting device can automatically adjust the fixing position according to the size of the fish, and the descaling device can also adjust the scale scraping structure according to the type and size of the fish to ensure consistent processing effects.
