As a device for lifting a net thrown into the sea from a ship, a device such as Utility Model Registration No. 0235825 is common, and it is common to form a plurality of rotating rollers and to make the net adhere to the rotating roller.

However, when the net is lifted in such a device, because the net is overlapped and lifted, the trapped fish species are stressed by the tension of the net, and thus the survival rate is lowered.

In addition, because the direction of the guide roller and the driving roller does not coincide, the net is often overlapped or entangled when the net is lifted. Therefore, the net must be repaired after the net is lifted or the net must be replaced if the breakage or entanglement is severe. The problem occurred.

In addition, the various netting machines devised to compensate for the overlap of the nets when lifting the above-mentioned problem also do not coincide with the direction of the driving rollers which are driven by the main roller and the guide rollers that hold the net direction. Due to the failure, the direction of tension acting on the driving roller and the net is dispersed so that more power is consumed than necessary.

The present invention has been made to solve the above-mentioned problems, and at the same time to solve the problem that the net is lifted by overlapping the lifting, the net can be lifted with a minimum power by matching the tension and the direction of the driving roller. It was made.

The present invention relates to a net lifting apparatus and method, and more particularly, by lifting the net thrown in the sea by configuring the direction of the drive roller driven by the guide roller hydraulic motor in the conventional net lifting operation The present invention relates to a net lifting device and method for improving tangling.
