Description

Technical Field

[0002] Crucian carp is a common freshwater aquaculture fish in my country, prized for its delicious meat and rich nutritional value, and in high market demand. Traditional crucian carp processing often involves manual methods for sorting, scaling, and gutting. This process is complex, labor-intensive, inefficient, and lacks standardized procedures, easily damaging the fish. Furthermore, direct human contact can lead to contamination of the aquatic products, making it difficult to meet the demands of large-scale, standardized aquatic product processing.

[0003] Currently, most of the automated fish processing equipment on the market is designed for larger fish. There is a lack of dedicated adaptation structures for the small size and laterally compressed body of crucian carp, which easily leads to problems such as fish conveying jams, incomplete scaling, and large deviations in gutting. In addition, the connection between the various processing steps is poor, and it is impossible to adjust according to the posture of each fish during the fish conveying process. The overall level of automation is low, and it is impossible to achieve integrated and continuous operation of crucian carp processing, which restricts the large-scale development of the crucian carp processing industry.

[0024] The push component 3 is used to push the fish released by the channel feeding and sorting component 2 to the conduction component 4.

[0025] The transmission component 4 is used to adjust the fish body to a position with its belly down and its head facing the descaling component 5 and then transport it to the descaling component 5.

[0026] The descaling component 5 is used to descale the fish.

[0027] The evisceration and gutting component 6 is used to cut open the belly of the fish and remove the internal organs after scaling.

[0028] like Figure 2 , 3 As shown, the multi-channel feeding and sorting assembly 2 in this embodiment includes a feeding bin 21, a three-channel inclined rail 22 is provided inside the feeding bin 21, and a roller 23 is provided inside the feeding bin 21, with the roller 23 located above the three-channel inclined rail 22. A discharge box 24 is provided below the feeding bin 21, and the three-channel inclined rail 22 is connected to the discharge box 24. An opening and closing assembly 25 is provided at the discharge port of the three-channel discharge box 24, which controls the opening and closing of the discharge port of the three-channel discharge box 24. The inner wall of the three-channel inclined rail 22 is smoothed, and with the rolling assistance of the roller 23, the fish body slides smoothly down the inclined rail.

[0029] like Figure 4As shown, the opening and closing assembly 25 in this embodiment includes a first motor bracket 251, a first reduction stepper motor 252, a gear 253, a rack 254, and a baffle 255.

[0030] like Figure 5 As shown, the pushing component 3 in this embodiment includes a second motor bracket 31, a second reduction stepper motor 32, a first coupling 33, a first lead screw 34, a first lead screw flange nut 35, a first lead screw flange nut bracket 36, a movable bracket 37, a sliding guide support assembly 38, and a conveying component 39. The second motor bracket 31 is fixed on the device base frame 1, and the second reduction stepper motor 32 is fixed on the second motor bracket 31. The second reduction stepper motor 32 is connected to the first lead screw 34 through the first coupling 33. The first lead screw flange nut 35 is screwed to the first lead screw 34. The first lead screw flange nut 35 is connected to the movable bracket 37 through the first lead screw flange nut bracket 36. The movable bracket 37 is slidably connected to the sliding guide support assembly 38, and the conveying component 39 is disposed on the movable bracket 37. The second reduction stepper motor 32 drives the first lead screw 34 to rotate, thereby driving the first lead screw flange nut 35 to move, and the first lead screw flange nut 35 then drives the movable bracket 37 to move. In the initial state, the movable support 37 is located below the discharge port of the three-channel discharge box 24, and then catches the fish released from the three-channel discharge box 24. Then the movable support 37 moves to the transmission component 4 and sends the fish into the transmission component 4.

[0031] The sliding guide support assembly 38 is provided in two sets, such as Figure 6 As shown, two sets of sliding guide support assemblies 38 are located on both sides of the first lead screw 34. Each sliding guide support assembly 38 includes an optical axis support 381, a first optical axis 382, ​​a first linear bearing support 383, and a linear bearing 384. The two ends of the first optical axis 382 are fixed to the device base 1 via the optical axis support 381. The first optical axis 382 is connected to the first linear bearing support 383 via the linear bearing 384. The first linear bearing support 383 is connected to the bottom of the movable bracket 37. The linear bearing 384 slides along the first optical axis 382, ​​ensuring the stability of the movable bracket 37 during translation.

[0032] The movable support 37 is equipped with three sets of conveying components 39, each set of conveying components 39 corresponding to one discharge port of the three-channel discharge box 24. For example... Figure 7 As shown, the conveying assembly 39 includes a first servo bracket 391, a fish storage compartment 392, a first servo 393, a rocker arm 394, a slide rail 395, and a movable tilting tray 396. The fish storage compartment 392 is fixed on the movable bracket 37. The first servo 393 is fixed on the movable bracket 37 via the first servo bracket 391, and is located below the fish storage compartment 392. The movable tilting tray 396 is disposed inside the fish storage compartment 392, and the slide rail 395 is disposed on the bottom surface of the movable tilting tray 396. One end of the rocker arm 394 is connected to the first servo 393, and the other end of the rocker arm 394 is slidably connected to the slide rail 395. The first servo 393 drives the rocker arm 394 to rotate, pushing the movable tilting tray 396 from horizontal to tilted, smoothly pushing the fish to the conveying assembly 4. The three sets of conveying assemblies 399 realize multi-station batch pushing, improving pushing efficiency.

[0033] like Figure 8 , 23 As shown, the transmission component 4 in this embodiment includes a sorting and feeding component 41, an upper channel ramp 42, a lower channel ramp 43, an outer tray 44, a partition 45, a rotatable tray 46, a second servo bracket 47, and a second servo 48. The sorting and feeding component 41 is used to receive the fish body pushed by the pushing component 3, and to make the fish body with the tail facing the upper channel ramp 42 fall into the upper channel ramp 42, and to adjust the fish body with the head facing the upper channel ramp 42 before sending it into the lower channel ramp 43.

[0034] The outer tray 44 is used to receive fish bodies output from the upper channel ramp 42 and the lower channel ramp 43. A rotatable tray 46 is located inside the outer tray 44. A second servo motor 48 is fixed to the side wall of the outer tray 44 via a second servo motor bracket 47. The rotatable tray 46 is connected to the second servo motor 48. A partition 45 is fixed inside the outer tray 44 and located below the rotatable tray 46. A fish outlet 441 is provided on the side wall of the outer tray 44, and the bottom wall of the outer tray 44 is inclined towards the fish outlet 441. Specifically, as shown... Figure 9 As shown, the sorting and material handling assembly 41 of this embodiment includes a sorting chute 411 fixed on the device base frame 1. A third servo motor 412 is provided at the bottom of the sorting chute 411. The output end of the third servo motor 412 is connected to a circular base plate 413. An arc-shaped lever plate 414 is provided on the circular base plate 413.

[0035] Before the fish from the pusher component 3 enters the rotatable tray 46, the first camera 8 identifies the direction of the fish's tail. If the fish's tail is facing the upper channel ramp 42, the fish is guided directly into the upper channel ramp 42 by the arc-shaped deflector 414, and then enters the outer tray 44. If the fish's head is facing the upper channel ramp 42, the circular base plate 413 drives the arc-shaped deflector 414 to rotate, causing the fish to fall into the lower channel ramp 43, then into the upper channel ramp 42 after passing through the lower channel ramp 43, and finally into the outer tray 44. This ensures that after the fish enters the outer tray 44, the head exits first from the fish outlet 441.

[0036] Then, when scaling, the fish must be kept belly down. Therefore, the fish in the outer tray 44 needs to be flipped over. The second camera 9 identifies the posture of the fish, and the rotatable tray 46 flips to the left or right according to the posture of the fish, so that the fish falls into the fish outlet 441 with its belly down.

[0037] like Figures 10-17 As shown, the descaling assembly 5 in this embodiment includes an upper movable support 51, a lower movable support 54, a synchronous torsion spring limiting assembly 52, a conveyor belt descaling drive assembly 53, a synchronous adjustment assembly 55, a torsion spring conveyor belt limiting clamping assembly 56, a shower cleaning assembly 57, a fish head positioning cover drive assembly 58, and a fish scale collection box 59.

Two sets of optical axis linear guide support assemblies 558 are provided on both sides of the forward and reverse threaded screw 554. When the fifth reduction stepper motor 552 drives the forward and reverse threaded screws 554, the two sets of screw flange nuts 556 can move in opposite directions, thereby adjusting the distance between the two sets of conveyor belt type descaling drive components 53 to accommodate fish of different sizes and firmly clamp the fish. In addition, optical axis linear guide support components 558 are also provided on both sides of the synchronization adjustment component 55 to provide sliding support for the synchronization adjustment component 55.

The cover 587 blocks the fish body, achieving precise positioning of the fish body. The fourth reduction stepper motor 532 of the conveyor belt descaling drive component 53 drives the active roller 535 to rotate, driving the descaling conveyor belt 536 to operate. The fish scales are peeled off through friction and fall into the fish scale collection box 59. After processing, the cover 587 flips upward, and the conveyor belt descaling drive component 53 continues to drive the fish body forward to the evisceration component 6.

[0041] The synchronous torsion spring limiting assembly 52 is used to clamp the upper ends of the two sets of conveyor belt descaling drive assemblies 53.

The synchronous pulley 64 drives several sets of tension spring double blade assemblies 67 to rotate through the synchronous belt 65. The optical axis floating pressure assembly 68 is used to press the fish body onto the negative pressure adsorption bottom assembly 69; the optical axis floating pressure assembly 68 includes a fourth optical axis support 681 fixed on the device base frame 1, a fourth optical axis 682 connected to the fourth optical axis support 681, a floating spring 683 sleeved on the outer surface of the fourth optical axis 682, and an upper pressure plate 684 movably connected to the lower part of the fourth optical axis 682.

[0046] The spring-loaded double-blade assembly 67 is used to transport the fish on the negative pressure suction bottom assembly 69.

[0047] The negative pressure suction bottom component 69 is used to perform evisceration on the fish during the transport of the fish, and then suck out the internal organs after the evisceration is completed.

[0048] like Figure 20 As shown, the tension spring type double blade assembly 67 of this embodiment includes a vertical bearing seat 671, a tension spring 672, a variable diameter coupling 673, a first flange coupling 674, a first transmission plate 675, a second flange coupling 676, and a second transmission plate 677. The vertical bearing seat 671 is fixed on the device base frame 1. One end of the tension spring 672 is rotatably connected to the vertical bearing seat 671, and the other end of the tension spring 672 is connected to the first flange coupling 674 through the variable diameter coupling 673. The first transmission plate 675 is fixed on the first flange coupling 674. The second flange coupling 676 is connected to the first flange coupling 674, and the second transmission plate 677 is connected to the second flange coupling 676.

[0049] like Figure 22 , 24 As shown, the negative pressure suction bottom assembly 69 of this embodiment includes a seventh motor bracket 691, a seventh reduction stepper motor 692, a fourth coupling 693, a circular blade 694, a bottom groove 695, a suction head 696, and a negative pressure vacuum cleaner 697. The seventh reduction stepper motor 692 is fixed on the device base frame 1 through the seventh motor bracket 691. The seventh reduction stepper motor 692 is connected to the circular blade 694 through the fourth coupling 693. The bottom groove 695 is located above the circular blade 694, and the circular blade 694 extends out from the bottom groove 695. A support groove 6951 is provided on the bottom groove 695. The suction head 696 is located below the support groove 6951 and is connected to the negative pressure vacuum cleaner 697.

[0050] When the fish enters between the upper pressure plate 684 and the bottom groove 695, it pushes the upper pressure plate 684 upward along the optical axis 682. The floating spring 683 on the outer surface of the optical axis 682 is compressed and generates reverse elastic pressure, achieving flexible pressure on fish of different sizes and preventing the fish from shaking during gutting. Then, the tension spring double blade assembly 67 on both sides of the fish rotates in conjunction with the synchronous pulley 64 and synchronous belt 65, and the transmission plates A675 and B677 push the fish forward. The seventh reduction stepper motor 692 of the negative pressure suction bottom assembly 69 drives the circular blade 694 to rotate, cutting open the fish belly. At the same time as gutting, the fish continues to move forward, and the belly is expanded by the belly support groove 6951. Then, the negative pressure vacuum cleaner 697 generates negative pressure, and the suction head 696 quickly suctions the fish's internal organs.

[0051] The working principle of this invention is as follows: Before the equipment is started, the crucian carp to be processed are placed in batches into the feeding bin 21 of the multi-channel feeding and sorting component 2. The fish are assisted by rollers 23 to slide into the three-channel inclined rail 22 and finally gather into the three-channel discharge box 24. By driving the baffle 255 to move horizontally, the opening and closing frequency of the discharge port of the three-channel discharge box 24 is precisely controlled, so that the fish fall into the fish storage grid 392 of the pushing component 3 in an orderly manner. The first camera 8 monitors the status of the fish in the fish storage grid 392 in real time.

[0052] After receiving the fish, the fish storage compartment 392 of the push assembly 3 moves horizontally to the sorting and feeding assembly 41 of the transmission assembly 4. A first camera 8 is arranged next to the push assembly 3, with its lower part facing the fish storage compartment 392. Here, the head and tail orientation of the fish is identified and determined. The third servo motor 412 of the sorting and feeding assembly 41 drives the circular base plate 413 to rotate according to the recognition result of the first camera 8. Then, the movable tilting tray 396 adjusts the tilt angle to release the fish, ensuring that the tail of the fish enters the outer tray 44 first, and that the head of the fish exits from the fish outlet 441 first after entering the outer tray 44. When the fish slides down the inclined slide to the top of the outer tray 44, the second camera 9 next to the acrylic plate 45 accurately determines the back and belly orientation of the fish. If the posture is incorrect, the servo motor 48 drives the rotatable tray 46 to rotate for real-time correction, so that the fish falls into the fish outlet 441 with its belly facing down, and then slides smoothly into the descaling assembly 5.

[0053] Two sets of conveyor belt-type descaling drive components 53 transport the fish body to the fish head positioning cover drive component 58, which limits the fish body's position. Then, the two sets of conveyor belt-type descaling drive components 53 can perform the descaling operation on the fish body. The rinsing cleaning component 57 is connected to a water source to rinse and clean the fish body and conveyor belt in real time, removing residual scales and impurities. After descaling is completed, the fish head positioning cover drive component 58 flips upward, and the two sets of conveyor belt-type descaling drive components 53 continue to transport the fish body to the evisceration component 6.

[0054] The fish enters between the upper pressure plate 684 of the optical axis floating pressure assembly 68 and the bottom groove 695 of the negative pressure suction bottom assembly 69. The optical axis floating pressure assembly 68 can flexibly hold fish of different sizes, preventing the fish from shaking or shifting during gutting. Six sets of spring-loaded double blade assemblies 67 on both sides of the fish convey it forward. At the same time, the seventh reduction stepper motor 692 of the negative pressure suction bottom assembly 69 drives the circular blade 694 to rotate, gutting the fish from below. The abdominal support groove 6951 helps to enlarge the gutting incision. The negative pressure vacuum cleaner 697 is activated to generate negative pressure, and the suction head 696 in the middle of the bottom groove 695 quickly absorbs the fish's internal organs and blood, finally completing the integrated automated processing of the crucian carp.

[0055] Throughout the entire process, the first camera 8 and the second camera 9 provide real-time feedback on the fish's posture information. In conjunction with the coordinated control of various motors and servos, seamless connection and precise operation of each process are achieved, requiring no manual intervention throughout the entire process, thus meeting the needs of large-scale and standardized crucian carp processing.

[0056] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
