[0069] In this embodiment, the specific working principle of the lobster processing machine 100 is as follows: the lobster 7 is placed on the transfer platform 211 at the loading station manually or by a mechanical hand, and the first clamping block 231 and the second clamping block 232 can rotate under the drive of the clamping drive structure, that is, the driving gear, to clamp the lobster 7; after clamping, the electromagnetic relay 2211 is energized to attract the transfer platform 211 to the processing station, so that the shrimp head of the lobster 7 is under the shrimp head cutting tool 31, and the shrimp tail is located at the clamping station, and then the shrimp head cutting tool 31 and the back-opening cutting tool and the cleaning head can be operated simultaneously to cut off the shrimp head, cut the shrimp back, and clean the shrimp belly. Of course, the above-mentioned operation steps can also be performed separately and in sequence. At the same time, the wire taking clamp structure 611 moves to the wire taking station to clamp the shrimp tail. Under the drive of the wire pulling driver 62, the wire taking clamp structure 611 moves to the wire removing station to take out the shrimp line to complete the processing of the lobster 7. The transfer platform 211 then pops up under the action of the elastic reset member 2212 to reset to the loading station to prepare for entering the next processing flow.

[0070] Of course, a lobster 7 collection box may be provided below the cleaning head to recycle the processed lobsters 7, or they may be collected manually, which is not limited here.

[0071] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure made using the contents of the present invention specification and drawings, or directly or indirectly used in other related technical fields, is also included in the patent protection scope of the present invention.
