The right and left discs 508, 510 may be fitted to the hairtail along the tail of the hairtail.

The fin removing assembly 6 comprises a third fixing frame 601, a fourth fixing frame 602, a first double-pin electric sliding block 603, a second double-pin electric sliding block 604, a third double-pin electric sliding block 605, an adsorption gasket 606, a collection box 607, an infrared transmitter 608 and an infrared receiver 609; on one side of the conveying assembly 3 far away from the feeding assembly 1, a third fixing frame 601 and a fourth fixing frame 602 are fixedly connected with the support table 11 respectively; the first two-pin electric sliding block 603 is respectively connected with the top ends of the third fixing frame 601 and the fourth fixing frame 602 in a sliding manner; the second double-foot electric sliding block 604 and the third double-foot electric sliding block 605 are respectively connected with the top end of the first double-foot electric sliding block 603 in a sliding manner; an adsorption gasket 606 is respectively arranged on two sides of the second double-foot electric sliding block 604 and the third double-foot electric sliding block 605; below the first two-legged electric slider 603, the collection box 607 is in contact with the surface of the support table 11; an infrared receiver 609 is arranged on the third fixing frame 601 above the second double-pin electric sliding block 604; above the third two-foot electric slider 605, the third fixing frame 601 is provided with an infrared emitter 608.

The fin of the hairtail is torn off by the fin-removing component 6, firstly, when the rotating clamp unit 308 on the left rotating fixing plate 305 drives the hairtail to be positioned between the third fixing frame 601 and the fourth fixing frame 602, the hairtail is positioned between the second double-foot electric slide block 604 and the third double-foot electric slide block 605 in a head-up state, the first double-foot electric slide block 603 drives the connected components to move to one side of the third fixing frame 601 close to the left rotating fixing plate 305, then the second double-foot electric slide block 604 and the third double-foot electric slide block 605 respectively move towards the middle of the first double-foot electric slide block 603, so that the adsorption gaskets 606 on the second double-foot electric slide block 604 and the third double-foot electric slide block 605 clamp and adsorb the hairtail of the hairtail, then the rotating clamp unit 308 continues to drive the hairtail to move downwards, and simultaneously the first double-foot electric slide block 603 drives the connected components to move towards one side of the third fixing frame 601 close to the right rotating fixing plate 306, the whole dorsal fin of the hairtail is torn off smoothly from the tail to the head along the back of the hairtail, then the second double-pin electric sliding block 604 and the third double-pin electric sliding block 605 reset to loosen the torn dorsal fin, the dorsal fin falls into the collection box 607 to be recovered, and then the hairtail on the right rotating fixing plate 306 is torn off by the same working principle; in addition, when the first two-pin electric sliding block 603 moves, when the infrared receiver 609 receives an infrared signal sent by the infrared transmitter 608 and is interrupted, which indicates that the dorsal fin of the hairtail is successfully torn off, the conveying assembly 3 throws the hairtail into the second collecting box 9, and when the infrared receiver 609 receives an infrared signal sent by the infrared transmitter 608 and is not interrupted, which indicates that the dorsal fin of the hairtail is not successfully torn off, the conveying assembly 3 throws the hairtail into the third collecting box 10; the assembly completes the work of tearing the dorsal fin of the hairtail and the work of monitoring whether the dorsal fin of the hairtail is smoothly torn or not.

Although embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
