Description

Rotating fender netting device {a roatary type drift gill net hauling of net system}

The present invention relates to a rotary mesh network device.

In the net fishing net, the net is weighted on the bottom underline of the net, the top line has a float and the auxiliary line crossing the top line at the above line every 20-23m width, and the main line with one line in the direction of the net with a certain height from the top line. It is installed.

The fishing line is a rope used when the upper line of the body is placed in the water by a float and the main line is used to pull the drift net, so that the underline of the net touches the sea bottom. One worker and one worker to hold the auxiliary line, two winches installed on both sides of the cabin, three mainline workers attached to two guide rollers, three workers pulling the net from the deck, and the net Up to 12 workers were required, including two workers who worked together and two workers who organized other main and auxiliary lines.

In this way, the conventional mangyeonggi pulled the main line of the drift net with the foreign body, the deck, and the winches installed on both sides of the cabin, and required a lot of hands such as the arrangement of other auxiliary lines and the arrangement of the top line and the underline. Both nets were pulled from the foreign body side to the cabin, and the nets had to be pulled toward the side deck of the foreign material, so when there was a strong wind blowing during fishing, workers were swept away from the fishing gear while the hull tilted.

In addition, when the hull is rotated by birds or wind during fishing work, waste nets that frequently twist the auxiliary line and main line of the drift net lose the average 1,000 to 1,500 width nets per year. It was frequent, and the waste net was left unattended, and there were many difficulties in other water pollution and fishing work.

In addition, according to the conventional utility model registration application No. 20-1999-0015816 of 1999, the machine base and the machine base are composed of the machine body and the machine base, the machine base is firmly welded to the fishing boat, and the machine body is inserted into the base and freely left or right. The roller attached to the side plate of the machine body rotates the pinion by the hydraulic motor, the gear is rotated by the pinion, and the driven roller is mounted on the other two lower rollers by the drive chain sprocket assembled to the pinion and the drive shaft. There was a device to drive the chain sprocket.

In the wedge netting machine as described above, the driving device of the roller should be at least seven gears, and the internal structure is complicated in the prior art of the specification that connects the drive chain sprocket and the driven chain sprocket by a chain, in particular, the machine base is As it is fixed to the hull deck, it is inconvenient to arrange the work space with the left and right side of the deck according to the two wire work because it is not moved to the hull port or starboard. Due to a phenomenon in which the body and the upper line and the underline collide with the set of guide rollers formed on the inlet side by attaching the weight formed on the buoy or underline, the net lifting operation was not performed smoothly.

In addition, since most winch devices are fixed to foreign bodies or side decks, they cannot change their position to port or starboard according to fishing conditions, so they could not proceed smoothly, especially in fishing conditions where the wind direction changes frequently. Even if this is fixed or rotated, it was a form that is rotated without restoring force. This caused a lot of load on the net or main line, or the upper line or the underline, resulting in a lot of resistance to the operation of both machines.

In view of the above, in the present invention, in the configuration of the conventional network, by providing a new concept of the net network device, it is possible to operate the net network only by the underline and the upper line without the main line or auxiliary line that is essential for the conventional network In order to save the fishing gear of the net, and in particular, the main line is not exposed to the water surface to prevent netting and to prevent the net from being swept into the propeller of the sailing vessel.

In other words, the underline with weights at the bottom of the net and the upper end of the net are separated by two sets of wires separated by the distance between the top and the underline. It is to provide a rotatable netting device that is easy to harvest or useful for quickly cleaning the net.
