[0020] 1. When the ship is traveling on the Antarctic Ocean, the seawater will drive the impeller to rotate. The impeller drives the rotating shaft to rotate through the driving rod and multiple conical wheels. The rotating shaft drives the main shaft and the cylindrical block to rotate a certain angle each time through the grooved wheel mechanism, so that the multiple rectangular grooves set on the side wall of the cylindrical block can successively complete the processing operations such as loading shrimps, clamping shrimps, screening, washing shrimps, cutting shrimps, collecting shrimps, and quick freezing;

[0025] 6. After the shearing head removes the krill head, the slider drives multiple vertical rods and corresponding pistons to move upward through the horizontal plate.

[0047] One end of the rotating shaft 57 away from the motor 36 is fixedly connected to the first conical wheel 45, a connecting rod 47 is rotatably connected to the inner wall of the hull 1, the top of the connecting rod 47 is fixedly connected to the second conical wheel 46, the bottom wall of the hull 1 is fixedly connected to a support plate 49, the inner wall of the support plate 49 is rotatably connected to a driving rod 50, one end of the driving rod 50 is fixedly connected to an impeller 52, the other end of the driving rod 50 is fixedly connected to a fourth conical wheel 51, and the bottom end of the connecting rod 47 is fixedly connected to the third conical wheel 48.

[0048] The first conical wheel 45 and the second conical wheel 46 are meshed and connected, the third conical wheel 48 and the fourth conical wheel 51 are meshed and connected, the side wall of the trapezoidal seat 2 is fixedly connected with a bearing plate 58, one end of the bearing plate 58 is fixedly connected with a conveying guide plate 59, and the conveying guide plate 59 is tiltedly arranged inside the cylindrical block 5.

[0049] In the present invention, the hull 1 travels on the Antarctic Ocean, and the krill caught are placed in the lower shrimp box 55 on the hull 1. Since the hull 1 travels on the Antarctic Ocean, the water in the ocean will drive the impeller 52 to rotate, and the impeller 52 drives the fourth conical wheel 51 to rotate through the driving rod 50, then the fourth conical wheel 51 drives the linkage rod 47 to rotate through the third conical wheel 48, and the linkage rod 47 drives the rotating shaft 57 to rotate through the second conical wheel 46 and the first conical wheel 45, and the rotating shaft 57 drives the active dial 37, the arc locking plate 38 and the round pin 39 fixedly connected to its side wall to rotate synchronously, so that the round pin 39 intermittently enters the radial groove part of the groove wheel 40 to slide, and then drives the main shaft 18 to rotate a certain angle each time through the groove wheel 40. In the figure, the number of radial grooves of the groove wheel 40 is six, then the main shaft 18 will rotate sixty degrees each time, and the main shaft 18 will drive the cylindrical block 5 to rotate a certain angle each time.

[0050] A plurality of conveying pipes 56 are directly opposite to a plurality of rectangular grooves 6 located on the same axial direction on the cylindrical block 5. Workers pass the krill through the plurality of conveying pipes 56 in sequence into the corresponding rectangular grooves 6 to complete the shrimp loading operation. At this time, the electromagnet 9 arranged on the inner wall of the rectangular groove 6 is energized through the controller. The energized electromagnet 9 and the adjacent magnetic slide 8 have the same polarity and are magnetically repulsive to each other. Then, the energized electromagnet 9 will cause the magnetic slide 8 to slide sealedly for a distance under the action of the magnetic repulsion force. The magnetic slide 8 will squeeze the water inside the cavity 7, so that the water will be sprayed out from the plurality of flushing nozzles 53 to flush the krill entering the rectangular groove 6, thereby completing the shrimp washing operation. In addition, the magnetic slide 8 will also drive the clamp 11 to move through the support rod 10, so that the two clamps 11 inside each rectangular groove 6 move toward each other, and then the two clamps 11 clamp and fix the krill from both ends to complete the shrimp clamping operation.

[0051] Since the sliding displacement of the magnetic slide plate 8 in the cavity 7 is fixed, the sliding displacement of each clamping plate 11 is also fixed, that is, the distance between the two clamping plates 11 is fixed. When the krill are small in size, the two clamping plates 11 will not produce enough clamping force on the smaller krill. Then, when the cylindrical block 5 continues to rotate, these smaller krill will slide out from the rectangular groove 6 to the trapezoidal seat 2 for screening, thereby completing the screening and processing operation of krill of different sizes and completing the krill screening operation.

[0052] And because the upper and lower surfaces of the isolation plate 14 are both inclined surfaces with a height difference, each krill will slide a certain distance under the action of its gravity after entering the rectangular groove 6 and contacting the isolation plate 14, and will be positioned against the inner wall of the rectangular groove 6, so as to facilitate the punching and shearing of the krill heads by the scissor head 27.

[0053] When the rectangular groove 6 containing krill moves to the vertical upward direction with the cylindrical block 5, since one end of the main shaft 18 is fixedly connected to the circular plate 41, the first circular shaft 42 eccentrically fixedly connected to the side wall of the circular plate 41 will drive the second circular shaft 44 to move through the push rod 43, and then the second circular shaft 44 will drive the slider 20 to slide back and forth along the vertical direction on the inner wall of the bracket 19. At this time, the slider 20 will drive the cross plate 21 to move downward in the vertical direction for a distance, and the multiple vertical rods 23 set on the bottom wall of the cross plate 21 will drive the processing box 24 to move downward through the tension spring 26. When the punching shear head 27 contacts the krill shrimp head part, due to the small stiffness coefficient of the tension spring 26, the multiple vertical rods 23 It will continue to move downward for a distance, and each vertical rod 23 will drive the piston 25 fixedly connected at its bottom end to slide sealedly for a distance inside the processing box 24, and then the piston 25 will draw the liquid nitrogen inside the liquid nitrogen tank 22 into the processing box 24 through the one-way air inlet pipe 28. When the tension spring 26 is compressed to the end of the stroke, the vertical rod 23 drives the processing box 24 to move downward for a distance through the piston 25 and the tension spring 26, so that the punching and shearing heads 27 fixedly installed on the bottom wall of the processing box 24 punch and shear the shrimp head part of the krill, completing the shrimp shearing operation, and each isolation plate 14 is provided with a knife drop groove cooperating with the punching and shearing heads 27, thereby completing the operation step of removing the shrimp heads in the krill processing.

[0054] The krill shrimp head after punching and shearing will enter the rectangular hole 35 of the recovery box 31, and the krill shrimp head will squeeze the two wedge blocks 34, so that the two wedge blocks 34 slide into the corresponding recovery grooves 32, and then the krill shrimp head enters the recovery box 31 through the rectangular hole 35, and then the two wedge blocks 34 slide in the opposite direction for a distance to limit the krill shrimp head entering the recovery box 31.

[0055] After the processing box 24 drives the scissor head 27 to remove the krill head, the slider 20 will move upward in the vertical direction, then the horizontal plate 21 will drive the multiple vertical rods 23 to move upward synchronously, then the vertical rods 23 will drive the piston 25 to slide upward in a sealed manner, and the piston 25 will squeeze the liquid nitrogen inside the processing box 24 through the one-way air outlet pipe 29 to the nozzle 30 for spraying. The nozzle 30 is facing the krill tail part, and then the processed krill tail part is quickly frozen to complete the quick freezing operation.

[0056] Then, the electromagnet 9 is powered off, and the two clamps 11 move in the opposite direction to release the krill, and the output end of the micro motor 15 drives the isolation plate 14 fixedly connected thereto to rotate 180 degrees, so that the krill tails on the isolation plate 14 fall onto the conveying guide plate 59 during the rotation of the isolation plate 14, and the processed krill tails slide down on the conveying guide plate 59 and are collected.

[0057] The output end of the motor 36 is not provided with a locking mechanism, and can rotate freely during the above process. When the hull 1 is stationary, the motor 36 can be turned on to drive the shaft 57 to rotate, and the shaft 57 drives the grooved wheel mechanism to move, thereby achieving the above processing purpose.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
