Description

Technical Field

[0001] This invention relates to the field of leech farming technology, and more specifically, to a high-density intelligent leech farming device. Background Technology

[0002] Leeches have significant medicinal value and are widely used in traditional medicine, beauty and health care, and scientific research, making them important for human health and scientific research. However, traditional leech farming methods are relatively simple and have drawbacks such as low space utilization, inconvenient management, and susceptibility to external environmental influences.

[0003] Currently, leech farming mainly employs traditional extensive outdoor farming or intensive farming models. These traditional models rely heavily on the natural environment and human experience, often increasing stocking density to boost yields. This can easily lead to a sharp drop in dissolved oxygen levels in the water, rapid accumulation of harmful metabolites such as ammonia nitrogen and nitrite, and rapid water quality deterioration. This not only inhibits the normal growth and reproduction of leeches but also triggers outbreaks and cross-infections of various bacterial and fungal diseases, causing large-scale leech mortality. Therefore, under traditional models, there is a clear upper limit to yield per unit area, and economies of scale cannot be achieved simply by increasing density. In the leech farming process, key production steps such as feeding, pond inspection, and water changes rely heavily on the personal experience of the farmers, lacking scientific and quantitative data support. This extensive management approach is labor-intensive, has high labor costs, and is difficult to replicate and promote using standardized processes.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention.

Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this invention, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] like Figures 1-2 As shown, this embodiment provides a high-density intelligent leech farming device, including: Support frame 1, with multiple breeding boxes 2 slidably connected to its two sides; The opening and closing mechanism 3 is located in the middle of the support frame 1. The opening and closing mechanism 3 is used to expand the breeding box 2 to the outside of the support frame 1 or to store it inside the support frame 1. The opening and closing mechanism 3 is connected to the observation mechanism 4, which is used to acquire the internal image information of the breeding box 2 after it is expanded. The drainage mechanism 5 is connected to multiple breeding tanks 2 and is used to discharge wastewater from the breeding tanks 2 in a measured amount. Water injection mechanism 6 is connected to multiple breeding tanks 2 and is used to inject a certain amount of breeding water into the breeding tanks 2. The feeding mechanism 7 is connected to multiple breeding boxes 2 and is used to feed artificial feed into the breeding boxes 2 in a timely and quantitative manner. The digital display controller 8 is communicatively connected to the opening and closing mechanism 3, the observation mechanism 4, the drainage mechanism 5, the water injection mechanism 6, and the feeding mechanism 7. The digital display controller 8 is used to connect to mobile devices through a cloud platform for remote access and settings.

[0022] Understandably, when leeches are raised, juvenile leeches are placed in multiple breeding boxes 2, and a fixed amount of breeding water is injected into each of the breeding boxes 2 through the water injection mechanism 6. During the leech breeding process, the digital display controller 8 controls the opening and closing mechanism 3 to unfold the breeding boxes 2 outside the support frame 1, and the observation mechanism 4 acquires the internal image information of the breeding boxes 2 after unfolding. Then, the opening and closing mechanism 3 retracts the breeding boxes 2 back into the support frame 1. The digital display controller 8 controls the opening and closing mechanism 3 to unfold and retract the multiple breeding boxes 2 one by one. The observation mechanism 4 acquires the internal image information of the multiple breeding boxes 2 after unfolding. The digital display controller 8 uploads the internal image information of the multiple breeding boxes 2 after unfolding to the cloud platform so that staff can view it through mobile devices. Furthermore, staff can remotely set the inspection interval of the opening and closing mechanism 3, the drainage interval of the drainage mechanism 5, the water injection volume of the water injection mechanism 6, and the feeding interval of the feeding mechanism 7 through mobile devices. The system controls the opening and closing mechanism 3, observation mechanism 4, drainage mechanism 5, water injection mechanism 6, and feeding mechanism 7 to replenish the leeches. At the end of the set drainage interval, the digital display controller 8 controls the drainage mechanism 5 to discharge 30%-50% of the wastewater from the breeding tank 2. Then, the digital display controller 8 controls the water injection mechanism 6 to inject the corresponding amount of water into the breeding tank 2, thus updating the breeding water. At the end of the set feeding interval, the digital display controller 8 controls the feeding mechanism 7 to add a fixed amount of artificial feed to the breeding tank 2. The digital display controller 8 controls the opening and closing mechanism 3, observation mechanism 4, drainage mechanism 5, water injection mechanism 6, and feeding mechanism 7 to operate sequentially until the leeches reach the required sales standard. In this technical solution, the opening and closing mechanism 3, in conjunction with the observation mechanism 4, allows for regular inspection of the leech breeding situation in the breeding tank 2. The drainage mechanism 5, in conjunction with the water injection mechanism 6, regularly updates the breeding water in the breeding tank 2. The feeding mechanism 7 adds artificial feed to the breeding tank 2 in a timely and quantitative manner, achieving high-density intelligent leech breeding.

[0023] It should be noted that, as Figure 12 As shown, the breeding box 2 is connected to an anti-climb net 21, and the anti-climb net has an opening 22; The breeding box 2 is slidably connected to the support frame 1 via a three-section slide rail 23. A baffle is provided on the front side of the breeding box 2, which is used to mechanically limit the movement after it comes into contact with the support frame 1.

[0024] like Figure 3 and Figure 12 As shown, the opening and closing mechanism 3 includes: Support plate 31 is fixedly connected inside support frame 1. Support plate 31 is equipped with two guide rods 32. Support plate 31 is connected to lead screw 33 through bearing seat. Lead screw 33 is driven by servo motor 34. Guide slider 35 is slidably connected on guide rod 32. Lead screw slider is threadedly connected on lead screw 33. L-shaped base plate 36 is connected to guide slider 35 and lead screw slider, and positioning component 37 is connected to L-shaped base plate 36; The T-shaped cantilever 38 is rotatably connected to the middle position of the L-shaped base plate 36 via bearings. The T-shaped cantilever 38 is connected to the positioning component 37 for transmission. The positioning component 37 is used to control the deflection of the T-shaped cantilever 38. The two sides of the T-shaped cantilever 38 are respectively connected to the dial motor 39, and the dial motor 39 is connected to the friction roller 310. The side wall of the breeding box 2 is connected to the friction strip 24, which is set to correspond to the friction roller 310. After the T-shaped cantilever 38 deflects, the friction roller 310 abuts against the corresponding friction strip 24.

[0025] Understandably, when the breeding box 2 is extended outside the support frame 1, after the set inspection interval, the digital display controller 8 controls the servo motor 34 to rotate clockwise or counterclockwise a set number of times. The lead screw 33 drives the lead screw slider to move up or down on the support plate 31. Through the connection between the L-shaped base plate 36 and the guide slider 35, the guide rod 32 restricts the L-shaped base plate 36 to only slide up and down, preventing the L-shaped base plate 36 from rotating with the lead screw 33. Thus, through the connection between the L-shaped base plate 36 and the lead screw slider, the helical motion of the lead screw 33 is converted... The linear motion of the L-shaped base plate 36 allows it to move upwards or downwards along with the lead screw and slider, raising and lowering it to the corresponding height position of the breeding box 2 to be unfolded. Then, the digital display controller 8 controls the positioning component 37 to drive the T-shaped cantilever 38 to rotate clockwise, causing the friction roller 310 on one side of the T-shaped cantilever 38 to abut against the friction strip 24 on one side of the breeding box 2. Subsequently, the digital display controller 8 controls the start of the dialing motor 39, which drives the friction roller 310 to rotate. In cooperation with the friction strip 24, the breeding box 2 is pushed to slide and unfold along the three-section slide rail 23. After the breeding box 2 is unfolded outside the support frame 1, it is supported and erected by the three-section slide rail 23. After the observation mechanism 4 obtains the internal image information of the breeding box 2 after unfolding, the box-moving motor 39 drives the friction roller 310 to rotate in the opposite direction, thereby retracting the breeding box back into the support frame 1. Then, the positioning component 37 drives the T-shaped cantilever 38 to deflect counterclockwise, so that the friction roller 310 on the other side of the T-shaped cantilever 38 is in contact with the friction roller 310 on the other side of the T-shaped cantilever 38. The friction strip 24 on the other side of the breeding box 2 abuts against the support frame 1, unfolds the breeding box 2 on the other side to the outside of the support frame 1, acquires internal image information, and is then stored in the support frame 1. The positioning component 37 drives the T-shaped cantilever 38 to reset, and then the L-shaped base plate 36 is raised and lowered to another height position. Then the breeding boxes 2 on both sides at the other height position are unfolded and stored in turn. This process is repeated until all breeding boxes 2 have completed the unfolding and storage process. In this way, in conjunction with the observation mechanism 4, the leech breeding situation in the breeding box 2 can be inspected regularly.

[0026] It should be noted that a position monitoring sensor is installed on the L-shaped base plate 36. The position monitoring sensor is connected to the digital display controller 8. The position of the L-shaped base plate 36 is determined by the signal of the position monitoring sensor. The digital display controller 8 sends a command to drive the servo motor 34. With the monitoring of the position monitoring sensor, the L-shaped base plate 36 is moved to the target level.

[0027] like Figure 4 As shown, the selection component 37 includes: The selected motor 371 is mounted on the L-shaped base plate 36; One end of the lever 372 is connected to the selection motor 371 via a coupling 373; The outer ring of the spherical bearing 374 is connected to the T-shaped cantilever 38, and the other end of the lever 372 is slidably connected to the inner ring of the spherical bearing 374.

[0028] Understandably, when the T-shaped cantilever 38 is deflected, the digital display controller 8 controls the positioning motor 371 to rotate clockwise or counterclockwise by a set angle. The positioning motor 371 drives the lever 372 to deflect through the coupling 373. After the lever 372 slides in the spherical bearing 374, it drives the T-shaped cantilever 38 to deflect accordingly, so that the friction roller 310 on one side of the T-shaped cantilever 38 abuts against the friction strip 24 on the corresponding breeding box 2. Driven by the friction roller 310, after the breeding box 2 completes the unfolding and retraction process, the digital display controller 8 controls the positioning motor 371 to reset, and the lever 372 drives the T-shaped cantilever 38 to reset, so that the friction roller 310 moves away from the friction strip 24.

[0029] like Figure 3 As shown, observation unit 4 includes: The observation base plate 41 is connected to the opening and closing mechanism 3 via a transmission connection. An adjusting motor 42 is fixedly connected to the observation base plate 41, and the adjusting motor 42 is driven by an L-shaped cantilever 43. Camera 44 is connected to L-shaped cantilever 43. Camera 44 is used to obtain internal image information of the breeding box 2 after it is unfolded, after rotating and adjusting with L-shaped cantilever 43.

[0030] Understandably, after the observation base plate 41 moves synchronously with the L-shaped base plate 36, the positioning component 37 drives the T-shaped cantilever 38 to deflect to the left, causing the friction roller 310 on the left side to move backward against the friction strip 24 on the side wall of the breeding box 2 on the left side. The dial motor 39 on the left side drives the friction roller 310 to rotate counterclockwise. After the breeding box 2 on the left side slides along the three-section slide rail 23, the breeding box 2 on the left side unfolds outside the support frame 1. Then, the digital display controller 8 controls the adjustment motor 42 to rotate clockwise by a set angle. After the L-shaped cantilever 43 rotates, the camera 44 is positioned above the unfolded left-side breeding box 2. The camera 44 acquires internal image information of the unfolded breeding box 2 on the left side. The digital display controller 8 then uploads the acquired internal image information to the cloud platform so that staff can view it remotely. Subsequently, the dialing motor 39 on the left side drives the friction roller 310 to rotate clockwise. After the breeding box 2 slides along the three-section slide rail 23, the breeding box 2 on the left side is stored in the support frame 1. The positioning component 37 then drives the T-shaped cantilever 38 to reset. Similarly, after the observation base plate 41 moves synchronously with the L-shaped base plate 36, the positioning component 37 drives the T-shaped cantilever 38 to deflect to the right, causing the friction roller 310 on the right side to move backward against the friction strip 24 on the side wall of the right-side breeding box 2. The right-side dialing motor 39 drives the friction roller 310 to rotate clockwise. After the breeding box 2 on the right side slides along the three-section slide rail 23, the breeding box 2 on the right side unfolds outside the support frame 1. Then, the digital display controller 8 controls the adjusting motor 42 to rotate counterclockwise by a set angle, so that... After the L-shaped cantilever 43 rotates, the camera 44 is positioned above the right-side breeding box 2 after it has been unfolded. The camera 44 acquires the internal image information of the right-side breeding box 2 after it has been unfolded. The digital display controller 8 then uploads the acquired internal image information to the cloud platform so that staff can view it remotely. Subsequently, the dialing motor 39 on the right side drives the friction roller 310 to rotate counterclockwise. After the breeding box 2 slides along the three-section slide rail 23, the right-side breeding box 2 is stored in the support frame 1. The positioning component 37 then drives the T-shaped cantilever 38 to reset. This process continues until camera 44 acquires internal image information of multiple aquaculture boxes 2 after they have been unfolded.

[0031] like Figure 5 As shown, the drainage mechanism 5 includes: The first sealed box 51 is connected to a drain pipe 52, and a first solenoid valve is provided on the drain pipe 52. Two guide pipes 53 are connected to the support frame 1. The two ends of the guide pipes 53 are closed. A guide branch pipe 54 is connected to the guide pipe 53. The guide branch pipe 54 is connected to the first sealed box 51. Multiple first hoses 55 are connected to the guide pipes 53. The first hoses 55 are connected to a connecting pipe 56. The connecting pipe 56 is connected to the bottom end of the breeding box 2. A second solenoid valve 57 is provided on the connecting pipe 56. Vacuum pump 58 is connected to the first sealed box 51.

[0032] Understandably, after the set drainage interval ends, the digital display controller 8 controls the vacuum pump 58 to start for a set duration. The vacuum pump 58 expels the air from the first sealed box 51, creating a negative pressure. The negative pressure value inside the first sealed box 51 is -10kPa to -15kPa. By limiting the negative pressure value inside the first sealed box 51, effective drainage can be ensured while avoiding negative impacts on the leeches. Subsequently, the digital display controller 8 controls the second solenoid valve 57 on any of the connecting pipes 56 to open for a set duration. When the second solenoid valve 57 is open, under the action of the negative pressure inside the first sealed box 51, part of the wastewater corresponding to the breeding tank 2 enters the first sealed box 51 after passing through the connecting pipe 56, the first hose 55, the guide pipe 53, and the guide branch pipe 54. After the second solenoid valve 57 is closed, drainage stops, and the amount of wastewater discharged is 30%-50% of the total amount in the breeding tank 2. After the first solenoid valve on the drain pipe 52 is opened, the wastewater in the first sealed box 51 is discharged through the drain pipe 52 and collected in the waste liquid pool or waste liquid container. The digital display controller 8 controls the water injection mechanism 6 to inject a certain amount of breeding water into the breeding tank 2. After the wastewater in the first sealed box 51 is discharged, the first solenoid valve is closed. Then the digital display controller 8 controls the vacuum pump 58 to start for a set time. After the vacuum pump 58 discharges the air in the first sealed box 51 to form a negative pressure, the digital display controller 8 controls the second solenoid valve 57 on another pair of pipes 56 to open for a set time. This process is repeated until the wastewater in multiple breeding tanks 2 is discharged.

[0033] like Figure 5 As shown, a water quality detection sensor 59 is connected through the first sealed box 51, and the water quality detection sensor 59 is communicatively connected to the digital display controller 8.

[0034] Understandably, after the wastewater in the breeding tank 2 enters the first sealed tank 51, the newly entered wastewater mixes and dilutes with the small amount of wastewater remaining in the first sealed tank 51. Since the amount of newly entered wastewater is much greater than the amount of wastewater remaining in the first sealed tank 51, and both are used for leech farming, the small amount of residual wastewater will only have a minor impact on the final test value of the newly entered wastewater. The water quality sensor 59 detects small deviations in the dissolved oxygen, pH, ammonia nitrogen, nitrite, temperature, and turbidity data of the newly entered wastewater. The small deviation data detected by the water quality sensor 59 is collected by the digital display controller 8 and uploaded to the cloud platform. This allows staff to adjust the drainage interval of the drainage mechanism 5, the water injection volume of the water injection mechanism 6, and the feeding interval and feeding amount of the feeding mechanism 7 based on the small deviation data of the wastewater in each breeding tank 2, so as to ensure the normal growth of leeches in each breeding tank 2 and reduce the occurrence of diseases.

[0035] like Figures 6-7 As shown, the water injection mechanism 6 includes: The second sealed box 61 is connected to a water inlet pipe 62, and a third solenoid valve 63 is provided on the water inlet pipe 62. Metering pump 64, whose output end is connected to water inlet pipe 62, and whose input end is used to connect to water source; A pressure pump 65 is connected to a pressure pipe 66, which is connected through the second sealing box 61. The end of the pressure pipe 66 is close to the bottom of the inner side of the second sealing box 61. The first adapter component 67 has an input end connected to an outlet pipe 68, which is connected through the second sealed box 61. The end of the outlet pipe 68 is close to the inner bottom of the second sealed box 61. The output end of the first adapter component 67 is connected to a plurality of second hoses 69, which are connected through the breeding box 2. The first adapter component 67 is used to adjust the outlet pipe 68 to communicate with the corresponding second hoses 69. The first row of rods 610 is connected to the support frame 1. The first row of rods 610 is provided with a plurality of first limiting cylinders 611. The middle part of the second hose 69 is connected to the first limiting cylinder 611.

[0036] Understandably, after the wastewater in the breeding tank 2 is discharged and the second solenoid valve 57 is closed, the digital display controller 8 controls the third solenoid valve 63 to open. The metering pump 64 draws a fixed amount of water through the inlet pipe 62 into the second sealed tank 61. Subsequently, the third solenoid valve 63 closes, and the digital display controller 8 regulates the first adapter component 67 to connect the outlet pipe 68 with the corresponding second flexible hose 69. The digital display controller 8 then controls the pressurization pump 65 to start. The pressurization pump 65 injects air into the second sealed tank 61 through the pressurization pipe 66. The air mixed with the water in the second sealed tank 61 increases the oxygen content in the water. After the pressure in the second sealed tank 61 increases, under the action of pressure, the second... Water in the sealed box 61 enters the first transfer assembly 67 through the outlet pipe 68. After flowing through the first transfer assembly 67, it is injected into the breeding box 2 through the corresponding second hose 69, thereby injecting a certain amount of breeding water into the breeding box 2. The pressure of the pressurizing pump 65 is 5kPa-10kPa. By limiting the pressure of the pressurizing pump 65, the pipe resistance and water level difference are overcome to achieve stable water intake, while avoiding direct physical damage and stress to the leeches. The second hose 69 is arranged and limited by the first arrangement rod 610 and multiple first limiting cylinders 611 to prevent the second hose 69 from getting tangled and bent during the movement of the breeding box 2.

[0037] like Figure 8 As shown, the first adapter component 67 includes: A sealing housing 671 is connected to the outside of the second sealing box 61. The bottom end of the sealing housing 671 is provided with a plurality of first mating holes 672. The first mating holes 672 are connected to first connectors 673. The second hose 69 is connected to the first connectors 673. The outlet tube 68 is connected to the top end of the sealing housing 671. The adapter post 674 is sealed within the sealing housing 671. An entry chamber 675 is formed between the top of the adapter post 674 and the sealing housing 671. The adapter post 674 is provided with a first adapter hole 676. A first sealing cone 677 is connected to the bottom of the first adapter hole 676. The first sealing cone 677 passes through the first mating hole 672. The drive motor 678 is connected to the sealed housing 671, and the drive motor 678 is connected to the adapter post 674 for transmission.

[0038] Understandably, when connecting the outlet tube 68 to the corresponding second flexible tube 69, the digital display controller 8 adjusts the drive motor 678 to rotate at a set angle, so that after the adapter post 674 rotates within the second sealing box 61, the first adapter hole 676 is adjusted to correspond with the corresponding first mating hole 672. During the rotation of the adapter post 674 within the second sealing box 61, the first sealing cone 677 bends between the bottom end of the adapter post 674 and the sealing housing 671. After the adapter post 674 rotates to its position, the first sealing cone 677 is positioned within the corresponding first mating hole 672. The second sealing box 61 expands to seal the gap between the first adapter hole 676 and the first docking hole 672. After the pressure inside the second sealing box 61 increases, the water inside the second sealing box 61 enters the inlet chamber 675 formed between the top of the adapter column 674 and the sealing shell 671 through the outlet pipe 68 under the action of the pressure. Then, it flows through the first adapter hole 676, the first sealing cone 677, the first docking hole 672, and the first docking connector 673 in sequence, and is injected into the corresponding breeding box 2 through the corresponding second hose 69, thereby injecting a certain amount of breeding water into the breeding box 2.

[0039] like Figures 9-10 As shown, the feeding mechanism 7 includes: The storage bin 71 is connected to the support 72, and the output end of the storage bin 71 is connected to the quantitative feeder 73; A mixing pipe 74 has a feed hopper 75 connected through its side end. The feed hopper 75 is connected to the output end of the quantitative feeder 73. An air pump 76 is connected to the tail end of the mixing pipe 74, and a connecting hose 77 is connected to the head end of the mixing pipe 74. The second adapter component 78 has its input end connected to the adapter hose 77, and its output end is connected to multiple third hoses 79. The third hoses 79 are connected to the breeding box 2. The second adapter component 78 is used to adjust the adapter hose 77 to connect with the corresponding third hose 79. The second row of rods 710 is connected to the support frame 1. The second row of rods 710 is provided with multiple second limiting cylinders 711. The middle part of the third hose 79 is connected to the second limiting cylinders 711.

[0040] Understandably, when the set feeding interval ends, the digital display controller 8 regulates the second transfer component 78 to connect the transfer hose 77 with the corresponding third hose 79. Subsequently, the digital display controller 8 controls the air pump 76 to start, which draws air and injects it into the mixing pipe 74, creating a pushing airflow within the mixing pipe 74, transfer hose 77, second transfer component 78, and corresponding third hose 79. The digital display controller 8 then controls the quantitative feeder 73 to start, which gradually and quantitatively outputs the artificial feed from the storage bin 71. Artificial feed enters the feeding hopper 75 and flows into the mixing pipe 74, where it mixes with the pushing airflow. Under the push of the airflow, the feed passes through the mixing pipe 74, the transfer hose 77, the second transfer component 78, and the corresponding third hose 79 before entering the corresponding breeding box 2. This allows for the timely and quantitative feeding of artificial feed into the breeding box 2. The third hose 79 is arranged and limited by the second arrangement rod 710 and multiple second limiting cylinders 711 to prevent it from becoming tangled or bent during the movement of the breeding box 2.

[0041] It should be noted that the pressure of the air pump 76 is 15kPa-25kPa. By limiting the output pressure of the air pump 76, the artificial feed can be stably delivered, while avoiding disturbing the leeches in the breeding box 2. The breeding box 2 is equipped with a buffer shell, which is set at the connection between the third hose 79 and the breeding box 2. The buffer shell buffers and slows down the artificial feed delivered by the pushing airflow, preventing the artificial feed from spraying out and harming the leeches in the breeding box 2.

[0042] Artificial feed is granular solid feed, which is the basic food source for leech farming. Natural feed is also placed in the farming tank 2, including golden apple snails, river snails, aquatic insects and their larvae, which are supplementary food sources for leech farming.

[0043] like Figure 11 As shown, the second adapter component 78 includes: Mounting base 781 is connected to bracket 72. A connecting plate 782 is integrally provided on the side end of mounting base 781. Multiple electric cylinders 783 are connected to the connecting plate 782. The electric cylinders 783 are connected to the bearing plate 784. A linear displacement stage 785 is connected to a bearing plate 784. A transition block 786 is connected to the linear displacement stage 785. A second transition hole 787 is provided through the transition block 786. One end of the second transition hole 787 is connected to a transition hose 77, and the other end of the second transition hole 787 is connected to a second sealing cone. The adapter plate 788 is connected to the mounting base 781. The adapter plate 788 is close to the adapter block 786. Multiple second mating holes 789 are arranged on the adapter plate 788. The second mating holes 789 are connected to second connectors. The second connectors are connected to the third hose 79. The second sealing cone passes through the second mating holes 789.

[0044] Understandably, when the adapter hose 77 is connected to the corresponding third hose 79, the digital display controller 8 controls multiple electric cylinders 783 to extend or retract synchronously, so that the bearing plate 784 carries the linear displacement stage 785 to rise and fall to the corresponding height position. Subsequently, the digital display controller 8 controls the linear displacement stage 785 to drive the adapter block 786 to perform the corresponding linear displacement, so that the second adapter hole 787 aligns with the corresponding second mating hole 789. During the movement of the adapter block 786, the second sealing cone bends between the adapter block 786 and the adapter plate 788. After 786 moves into place, the second sealing cone unfolds in the corresponding second docking hole 789, sealing the gap between the second adapter hole 787 and the second docking hole 789. The artificial feed enters the mixing pipe 74 from the feed hopper 75 and mixes with the pushing airflow. Under the push of the pushing airflow, the feed passes through the mixing pipe 74 and the adapter hose 77, then through the second adapter hole 787, the second sealing cone, the second docking hole 789, and the second connector, and is then guided into the corresponding breeding box 2 through the corresponding third hose 79, thereby quantitatively dispensing artificial feed into the breeding box 2.
