FIG. 7 is a simplified front view showing the overall configuration of a fish ovary removal device using the fish body conveying device 1 according to the present invention. The conveyor 70 has a plurality of buckets 71 on which fish bodies are placed laterally. The axis of the starting end sprocket wheel 73 of this conveyor 70 is horizontal, but the axis of the ending end sprocket wheel 74 is inclined at about 30 degrees. The vehicle runs while gradually increasing the angle of inclination.

A pair of upper and lower clamping belts 75 and 76 are conveyor 7
7 of the starting sprocket wheel at the end of 0.
7 and 78, and clamps the gill cover portion of the fish F mounted on the conveyor 70. The axes of the starting end sprocket wheels 77 and 78 are provided approximately parallel to the starting end sprocket wheel 73 of the conveyor 70, but the axes of the ending end sprocket wheels 79 and 80 are provided in the vertical direction, and the belts 75 and 76 are In the first half extending from the starting end to the center, the opposing direction is twisted, and in the second half, the opposing direction is horizontal. A rotary cutter 81 for cutting the fish body F is disposed in the rear half thereof so as to cut directly below the holding belts 75 and 76.

Immediately below the rear half portions of the clamping belts 75 and 76, a fish body conveying device 1 for grasping and conveying the tail portion of the cut fish body F is provided. Chains 2a and 2b of this fish conveyance device 1 are connected to a holding belt 7.
It is driven to travel at the same speed as or slightly faster than that of No. 5, 76. An egg collecting device 85 is provided after the chains 2a, 2b have changed their running from the outward route to the return route. Below the release point P2 (see Figure 5) at the end of the return path of chains 2a and 2b, there is a fish body F after egg collection.
A chute 91 is provided for winding up the material and guiding it to the next three-sheet grater 90.

The operation of the fish ovary extraction device having such a configuration will be explained. The fish F is fed by a conveyor 70, and then the gill cover portions of the fish are pinched by pinch belts 75 and 76, and in this state, the fish F is conveyed by the pinch belts 75 and 76 in the direction of the arrow.
At this time, due to the twisting of the clamping belts 75 and 76, the fish body F is placed in a vertical position with the tail downward, and the chain 2a,
2b gripping point P1 (see Figures 4 and 5)
When the fish F is supplied to the chain 2a, 2b, the tail of the fish F is held by the gripping means 6 attached to the chains 2a and 2b. The fish F is conveyed by chains 2a, 2b and clamping belts 75, 76, and cut near the base of the pectoral fin by a cutter 81.
By this cutting, the fish body F is attached to the clamping belts 75 and 76.
The ovary inside the fish body protrudes a little from the cut surface because it is released from the pressing force. Next, when passing through the end sprocket wheels 4a, 4b, the ovary protrudes slightly due to centrifugal force. When the fish F passes near the sprocket wheels 4a and 4b on the end side of the lower frame portion, it is pushed out by a device not shown in the egg collection device 85, and the ovaries are pushed out together with the body fluid. The fish F after egg collection is further conveyed in the direction of the arrow by chains 2a and 2b, released at a release point P2 (see FIG. 5), and hung on a three-piece grater 90 via a chute 91.

Effects As described above, according to the present invention, since the holding member is supported by the elastic member, the elastic force of the elastic member allows the holding member to be held uniformly and not to damage the fish body, regardless of the size variation of the fish body. It can be reliably gripped and transported with a moderate amount of pressing force.
