The driving roller 11 is arranged above the conveying belt 5 near the driving roller 3, and the driving roller 12 is arranged above the driving roller 4 at a position higher than the driving roller 11. Roll brushes 13, 14 and 15 are rotatably supported by the partition wall 2 at a predetermined interval while being substantially in contact with the conveyor belt 10. The conveyor belts 5 and 10 are for conveying fish, and preferably have a high friction coefficient so that the fish body does not swing.

Although the roll brushes 13 and 14 are arranged on the upper part of the conveyor belt 10, the roll brush 15 is arranged so as to face the drive roller 11 at the end portion of the conveyor belt 10. Then, the jet nozzles 17 and 18 are fixed to the partition wall 2 together with the pipes toward the portions where the roll brushes 13 and 14 substantially contact the conveyor belt 10. Further, on the back surface of the roll brush 15, an injection nozzle 19 is fixed to the partition wall 2 together with the pipe toward the space between the conveyor belts 10 and 5. The shape, number, angle, pressure, etc. of the injection nozzles 17, 18, 19 may be selected appropriately.

In order to support the conveyor belts 5 and 10, a fixed plate 50 that is in sliding contact with the back surface of the conveyor belts 5 and 10 is fixed to the partition wall 2. The transport belt 10 is provided with a large number of holes 10a (see FIG. 3) for opposition in the plate surface so that water can be easily discharged. In addition, the transport belt 5 is also provided with a large number of holes on the plate surface for discharging water. The roll brushes 6, 7, 13, 14, 15 have a function of holding the fish placed on the conveyor belts 5, 10 so as not to swing by the jet water, and have an appropriate amount for that purpose. It has elasticity. Therefore, the feature of the fish is that it is sandwiched between the conveyor belts 5 and 10 and the roll brushes 6, 7, 13, 14, and 15 when it is hit by the jet water.

The conveyor belts 5, 10 and the roll brushes 6, 7, 13, 14, 15 are independently driven by geared motors. As shown in FIG. 2, in order to rotate the drive roller 12 and the roll brushes 6, 7, and 15 around which the upper conveyor belt 10 is wound, the geared motor 32 is fixed to the partition wall 2 and its multiple output The pulley 30 of the drive roller 11 is rotated by the pulley 33 via the pulley belt 28, the multiple output pulley 33 and the coaxial compound pulley 35 of the roll brush 6 are combined with the pulley belt 34, and the coaxial compound pulley 35 and the roll brush are combined. 7, the coaxial compound pulley 37 is rotated by the pulley belt 36, and the pulley 30 of the driving roller 11 and the pulley 29 of the roll brush 15 are rotated by the pulley belt 38, all in the same direction.

Further, in order to rotate the drive roller 3 and the roll brushes 13 and 14 around which the lower conveyor belt 5 is wound, the geared motor 20 is fixed to the partition wall 2, and the pulley belt is attached to the multiple output pulley 21 thereof. The pulley 39 of the driving roller 4 is rotated via 22 and the multiple output pulley 21 and the coaxial compound pulley 25 of the roll brush 14 are combined with the pulley belt 23, and the coaxial compound pulley 25 and the coaxial compound pulley 27 of the roll brush 13 are combined. And are all rotated in the same direction by the pulley belts 26.

A belt 42 connects the output pulley 41 of the electric motor 40 and the pulley 43 of the pump 44 to the bottom of the frame base 2, and connects an appropriate water source to the pump 44 via a hose or the like. High-pressure water can be supplied from the pump 44 to the jet nozzles 8, 9, 17, 18, and 19 via a pipe 46, respectively.

To explain the operation of the above embodiment, the power source for driving the geared motors 20, 32 is operated to rotate the conveyor belts 5, 10, and the electric motor 40 is operated to remove high-pressure water. The fish 47, such as flatfish, is supplied from the tail side through the inlet 1b provided on the top plate 1a in FIG. 1 after supplying the jet nozzles 8, 9, 17, 18, and 19 to the conveyor belt 10. Drop 47 heads up. It should be noted that a configuration in which the fish 47 is thrown in from the head direction can also be selected by changing the type of fish or the direction of the injection nozzles 8, 9, 17, 18, 19.

Then, as shown in FIGS. 3 and 4, the fish 47 moves toward the conveyor belt 5 by the conveyor belt 10 and the roll brushes 13 and 14. At the portion where the fish 47 has passed the roll brush 13, the high-pressure water ejected from the ejection nozzle 17 hits the fish 47 and the scales 48 are peeled off. Further, the high-pressure water jetted from the jet nozzle 18 hits the portion where the fish 47 has passed the roll brush 14, and the scales 48 of the fish 47 are peeled off. Since the scales 48 are obliquely planted while overlapping from the head to the tail of the fish 47, the high-pressure water enters between the scales 48 and strips each one.

Then, in FIG. 1, when the fish 47 moves to the end portion of the conveyor belt 10, the fish 47 falls toward the conveyor belt 5 while being sandwiched between the roll brushes 15. At this time, the high-pressure water jetted from the jet nozzle 19 hits the side of the fish 47 from which the scales 48 have been peeled off, and the fish 47 drops onto the conveyor belt 5 with the side on which the scales 48 have not been dropped facing up. That is, the spray nozzle 19 assists in reversing the fish 47 when it falls on the conveyor belt 5.

Then, the fish 47 that has moved to the conveyor belt 5 moves while being sandwiched by the roll brushes 6 and 7, and scales on the side inverted by the high-pressure water jetted from the jet nozzles 8 and 9 are separated in the same manner as described above. Is done. Thus, the scales 48 on both sides of the fish 47 are dropped. Then, the fish 47 from which the scales 48 on both sides have been peeled off is discharged from the outlet 1c provided at the lower portion of the frame base 2 with the tail first.
