DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a fish processing machine for cutting the abdomen of a fish and removing internal organs and ribs within the abdominal cavity.

Prior Art A typical prior art is shown in Japanese Patent Application No. 61-288537 (Japanese Patent Publication No. 2-17140) filed by the applicant of the present invention. In this prior art, when a fish body with an incised abdomen is conveyed to the scraping member, the scraping member This resistance prevents the abdomen of the fish from escaping.

However, in such prior art, the outer peripheral surfaces of the guide rollers that come into contact with the outer surfaces of the abdomen of the fish body are
Since it is not formed in a shape that corresponds to the shape of the outer surface of the fish body, it is not possible to press the outer surface of the abdomen evenly over the entire surface, and as a result, the inner surface of the abdominal cavity cannot be brought into contact with the scraping member. There is a problem in that the internal organs or black skin cannot be reliably removed.

Problems to be Solved by the Invention Accordingly, an object of the present invention is to bring a processing member such as the scraping member into contact with the entire surface of the abdominal cavity to reliably perform a processing operation for reliably removing internal organs, black skin, etc. An object of the present invention is to provide a fish processing machine capable of performing the following.

Means for Solving the Problems The present invention involves incising the abdomen of a fish body being transported in the transport direction using an abdominal cutting blade, and inserting a processing member into the abdominal cavity of the fish body through which the abdomen has been cut to perform processing. In a fish processing machine that performs the above processing, support members having support surfaces having a shape corresponding to the shape of the outer abdominal surface of the fish body when the processing member is inserted into the abdominal cavity are provided adjacent to both sides of the processing member. This is a unique fish processing machine.

Function According to the present invention, supports having a shape corresponding to the shape of the outer abdominal surface of the fish body when the processing member is inserted into the abdominal cavity are provided adjacent to both sides of the processing member for treating the inside of the abdominal cavity of the fish body. Since the support member having a surface is provided, it is possible to prevent the incised abdomen from being displaced to both sides, and thereby the inner surface of the abdominal cavity can be brought into even contact with the processing member, Internal organs and black skin inside the abdominal cavity can be reliably removed.
