[0022] (1) The utility model sets a sorting component, starts a servo motor 1 through a controller, and the servo motor 1 drives the half gear to rotate through a rotating rod. Since the half gear is meshed with the reciprocating rack, the rotation of the half gear drives the reciprocating rack to move back and forth in the mounting seat. During this process, the guide block and the reciprocating rack move in coordination to ensure the linearity of the movement, so that the movement of the reciprocating rack is transmitted to the push rod, thereby realizing the reciprocating movement of the sorting frame, which is conducive to the sorting frame to shake and sort according to the size of the lobsters, and the use of two sorting frames improves the sorting efficiency;

[0023] (2) The utility model provides an opening and closing assembly. After the sorting operation is completed, the larger lobsters remain in the sorting frame. In order to take out the lobsters, the operator needs to press the driving rod downward. The movement of the driving rod causes the insert block to descend. As the driving rod moves, the spring performs a telescopic movement on the outer wall of the telescopic rod, and the anti-detachment block slides downward in the accommodating block. This series of movements causes the insert block to detach from the inside of the fixed block, thereby opening the revolving door. In this way, the lobsters can be smoothly taken out of the sorting frame, which is beneficial for the staff to quickly control the revolving door and can unload the lobsters at any time, thereby improving the operating efficiency and flexibility.

[0039] The implementation principle of the embodiment of the utility model is as follows: first, the two sorting frames 3 are respectively entered through the feed hopper 2. Secondly, the servo motor 1 501 is started through the controller. The servo motor 1 501 drives the half gear 503 to rotate through the rotating rod 502. Since the half gear 503 is meshed with the reciprocating rack 504, the rotation of the half gear 503 drives the reciprocating rack 504 to reciprocate in the mounting seat 12. In this process, the guide block 505 and the reciprocating rack 504 move in coordination to ensure the linearity of the movement, thereby transmitting the movement of the reciprocating rack 504 to the push rod 13, realizing the reciprocating movement of the sorting frame 3, thereby shaking and sorting the lobsters according to their size through the sorting frame 3. Next, the anti-stacking component 11 is started, and the servo motor 2 110 is started to drive the servo motor 2 110 to rotate the material dividing rod 112. Next, the material is divided. The rod 112 drives another dividing rod 112 to rotate through the conveyor belt 111, so that the two dividing rods 112 respectively turn over the lobsters in the two sorting frames 3 to prevent the lobsters from piling up during the sorting process. Finally, after the sorting operation is completed, the larger lobsters remain in the sorting frame 3. In order to take out the sorted lobsters, the staff needs to press the driving rod 16 downward. The movement of the driving rod 16 causes the insert block 703 to descend. As the driving rod 16 moves, the spring 702 telescopically moves on the outer wall of the telescopic rod 701, and the anti-slip block 704 slides downward in the accommodating block 14. This series of movements causes the insert block 703 to detach from the inside of the fixed block 15, thereby opening the revolving door 6. In this way, the lobsters can be smoothly taken out of the sorting frame 3. At the same time, the smaller lobsters enter the collection box 10 through the guide tube 8, thereby completing the lobster sorting operation.

[0040] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
