Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for efficiently collecting walleye and other cod roe.

Conventionally, attempts have been made to mechanically and continuously collect cod roe from the fish, but since the cod roe moves within the abdominal cavity, the roe may also be cut off when cutting the fish head, or the cod roe may be removed from the abdominal cavity. It is difficult to remove the cod roe smoothly and reliably without damaging the fish body or damaging both the fish body and the cod roe, and therefore, the current situation is that the fish is still collected manually.

The present invention is an attempt to improve these deficiencies with an extremely simple configuration.The present invention is an attempt to improve these defects by using an extremely simple configuration.The present invention is a transfer device that places and transfers the abdomen of a fish body in the direction of movement, and is installed so that the tail side is inclined downward. A fish head cutting rotary blade is provided at the tip, and a holding and transferring device is installed at least forward from the tip of the transfer device to hold the rear portion of the fish body trunk from both upper and lower sides, The main feature is that an extrusion spatula pulled by a spring for extruding the abdominal cavity and squeezing out the cod roe is vibably installed in the front part, and fish body guide pieces are formed on both upper and lower sides of the extrusion spatula.

An embodiment of the present invention will be described with reference to the drawings. A transfer device 1 for placing and transferring a fish body includes a transfer belt 2 for supporting a fish head.
and a transfer belt 3 which supports the front side of the torso and has the same length, a transfer belt 4 which supports the rear side of the torso and is longer than the transfer belts 2 and 3, and a transfer chain 5 which supports the tail. It is formed so that the fish body can be placed and transferred with the abdomen facing the direction of travel, and the tail side is lower.
It is installed tilted forward and backward.

A fish head cutting rotary blade 6 is pivotally supported between the distal ends of the transfer belts 1 and 2 so as to be rotated by appropriate power. An upper transfer belt γ and an upper transfer chain 8 are stretched so as to pinch and hold the sides and tail, and together they form a holding and transferring device 9 that pinches the rear part of the body of the fish.

An operating rod 11, the tip of which is pulled by a spring 10, is pivotally supported near the transfer belt 3 at the front of the fish head cutting rotary blade 6 so as to be substantially perpendicular to the direction of movement of the holding and transferring device 9. At the lower tip of the operating rod 11, an extrusion spatula 13 having a cross-section of 12 and 12 integrally formed with fish guide pieces 12 and 12 is fixed on both upper and lower sides so as to face substantially the rear side of the abdominal cavity.

In the embodiment of the present invention, cod such as walleye cod, which is constructed as described above, is transported by the transfer belts 2 and 3.
Transfer device 1 with the abdomen facing the direction of travel so that it is located between
When the fish is placed on the transfer device 1, the rear body and tail of the fish are held by the transfer bell I-4 of the transfer device 9.
．． :! The fish head is held between the upper transfer belt 7 and between the transfer chain 5 and the upper transfer chain 8, and transferred to the fish head cutting rotary blade 6 to cut the fish head.

Next, the rear side of the abdominal cavity of the fish body from which the fish head has been cut is brought into contact with the pushing spatula 13 by the holding and transferring device 9, and the abdominal cavity is pushed out by the elastic action of the pushing spatula 13 against the abdominal cavity and the flexible bending action of the front side of the fish body trunk. The cod roe that passes through the extrusion spatula 13 without being compressed is squeezed out from the fish head cutting section and collected.In this case, the fish body guide pieces 12.
12 prevents the abdominal cavity from coming off the extrusion spatula 13 and smoothes out the squeezing action by the extrusion spatula 13.

In addition, the holding and transferring device in the above embodiment was exemplified as holding at three places, the holding at the rear side of the torso and the holding at the tail, but when the holding force is large, it may be held at one place, or in order to increase the holding force. Furthermore, a pressure roll may be provided above the upper transfer belt, and two or more extrusion spatulas may be provided to ensure the squeezing action.

In the present invention, the fish body is transported with the abdomen facing the direction of travel using a transport conveyor installed so that the tail part is inclined downward, and the process of cutting the fish head and squeezing out the cod roe is carried out by holding and transporting the rear part of the body of the fish body. When cutting the fish head, the cod roe in the abdominal cavity is brought to the anal area at the rear of the abdominal cavity and is not damaged by the rotating fish head cutting blade.
Cod roe is squeezed out with an extrusion spatula, and the process of collecting cod roe in particular uses the elastic action of the extrusion spatula on the abdominal cavity and the flexible bending action of the front part of the body of the fish, creating a natural compression force similar to when squeezed out by hand. The cod roe can be smoothly and reliably squeezed out from the cut part of the fish head while adding it to the abdominal cavity.
In addition, the extrusion spatula has fish body guide pieces formed on its upper and lower sides that allow it to perform the squeezing action even more smoothly without coming off from the abdominal cavity, and has the advantage of being able to automatically and efficiently collect fish bodies and cod roe without damaging both the fish body and cod roe. It has the following characteristics.
