た構造とする。 A net roller device 3 is installed in the center hole 2 of the pedestal 1.
is pivotably mounted using the center pin of the swivel base 4 and the nut 5 (arrow a-a'). Bearings 6, 6' are provided on both sides of the swivel base 4, and clevises 8, 8' attached to opening/closing arms 7, 7' are pivotally connected by a shaft 9.
The clevis holder 10 attached to the lower surface of the swivel base 4 has a clevis 1 of the hydraulic cylinder 11.
1' is pivotally connected with a pin 12, and the rod fitting 13 is
Rod holder 1 provided at the lower end of the opening/closing arm 7
4 with a pin 12, and by expanding and contracting the hydraulic cylinder 11, the opening/closing arms 7, 7' are moved in the direction of the arrows b--b', c.
- It is installed at c′ so that it can be opened and closed. A net hauling roller shaft 15 is fixed to the upper end of the opening/closing arm 7 with a tightening nut 15', and the net hauling roller shaft 15 has a drum shape made of rubber or the like and slightly truncated conical. The shaft boss 16' of the net lifting roller 16 is rotatably mounted with a mounting nut 17. An internal gear 18 is attached to the inner surface of the net lifting roller 16, and a drive small gear 20 provided on the motor shaft 19' of the hydraulic motor 19 attached to the lower side of the net lifting roller shaft 15 is connected to the internal gear 18. In accordance with the forward and reverse rotation of the hydraulic motor 19, the net lifting roller 16 is provided so as to be rotatable in the direction of the arrow dd'.

圧接されている。 The net-lifting rollers 16 of the present net-lifting roller device 3 are provided symmetrically on the left and right and can be opened and closed, and the axes of the mutual rotation axes of the net-lifting rollers 16 are set slightly downward from the same straight line in a V-shape ( Since it is provided in the direction of the arrow e), the upper surface portion (arrow f) corresponding to the conical bottom surface is in contact with the conical bottom surface and is pressed by the hydraulic cylinder 11.

ることが可能である。 Therefore, the purse net 22 placed upside down on the net lifting roller 16 is bitten between the two rollers according to the rotation d of the net lifting roller 16, and is held therein.
As it continues to rotate, it passes the pressure contact point (arrow f') and is abandoned at the position where the pressure contact surface of the lifting net roller 16 separates (arrow g), so the purse net 22 naturally separates from the lifting net roller 16, so it continues. It is possible to carry out net fishing.

するものである。 As described above, the present invention allows the purse seine to be placed on the drum surface of the net-lifting roller for rotational hoisting, and at the same time, the purse-seine is automatically held and abandoned by the pressure contact surfaces of both net-lifting rollers, and both operations are performed in tandem. Therefore, it is an object of the present invention to provide a net-lifting roller device that enables continuous net-lifting and is characterized by saving labor in net-lifting work and shortening net-lifting time.
