Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for throwing a knotted net into the sea and a method for hauling the net onto a ship.

In conventional trawl methods, the net pennant and the reins connected to it are wound onto the same winch drum as the seine, so when casting the net, the reins and the seine are separated, and the otter board is removed in between. However, when hauling nets, the reins and seine are separated from the otter board.9
Work is required to combine the image tones.

SUMMARY OF THE INVENTION An object of the present invention is to provide a casting net that can reduce the time and labor required for casting net work by winding the net pennant and reins on a drum separate from the seine.

An embodiment of the present invention will be described based on the drawings. The trawl fishing net used in the seven-line fishing method is a conventional one, and as shown in FIG. Otsuterbouma 3 is installed between them. FIG. 2 shows a troll winch [1] used in this method, and this winch consists of a pair of left and right winches.

Each machine is powered by a hydraulic motor 13 and a main drum 17 which is driven via a gear 15. It is equipped with an auxiliary drum 19 and a sleeve drum 21, and the port side machine further has a center drum 23. These drums are each equipped with a clutch and a brake for optional convenience.

Reference numeral 25 is a clutch for coupling and hatching the port and starboard aircraft for 7 minutes.

In the state before casting the net, the otter board 27 is the same as before.

It is suspended and fixed to the gear loin 29 at the stern.

Further, the seine net 7 is wound onto the main drum 17 with its tip connected to the otter board 27. On the other hand, the net pennant 3 and the reins 5 connected thereto are wound onto the sub-drum 19 via the auxiliary rope 31.

When casting a net, first, as in the past, set the gear rotor 29.
Is V attached to I)? (Using a 9 wheel (not shown), the bottom end (fish catching part) 1a of the net body 1 is lowered with the stern winch 33 and dropped into the sea.

Due to the speed of the ship, the net body 1 is carried away, and the net pennant 3 connected to the net body 1 and the reins 5 following this are unwound from the sub-drum 19 (Figure 3). When the end of the rein 5 reaches the vicinity of the stern, the brake is applied to the auxiliary drum 19, and the end of one rein is connected to the otter board 27 and separated from the auxiliary rope 31. Next, the otter board 27 is released from the gear loin 29 and dropped into the sea. Then, as before, the seine net 7 is unwound from the main drum 17.

In this way, the seine net 7 is extended to an appropriate length according to the water depth and enters the seine state. In this state, Otterboard 2
7 receives the water flow and generates a lateral lifting force, which functions to spread the net.

When hauling a net, first, the main drum 17 is driven and the seine 7 is wound around it. After winding is completed, the otter board 27 is hung and fixed on the gear loin 29 in the conventional manner. Note that the seine net 7 is left connected to the otter board 27 in preparation for the first casting net. Next, the reins 5 are released from the otuta board 27 and connected to the auxiliary rope 3 drawn out from the auxiliary drum 19. After that, drive 411 with the secondary driver 1119, and give it the reins 5. Furthermore, wind up the net pennen 1-3. Next, the net 1 is pulled together with a robe (not shown) wrapped around the sleeve drum 21, and the short end 1\a is brought under the slipway 35 at the stern. The operation of the method is the same as before, with the center drum 23 and mast 37
The fish-catching part 1a of the net is pulled up from the slipway 35 onto the ship.

C/, l: As explained, this invention involves winding up the reins 5 and the net pennants 1-3 onto a special drum 19, and then using the otter board and reins, which were associated with the conventional method, with the casting net. This has the effect of eliminating the dangerous wires that combine or cause a minute F each time, and the time required for casting the net to be significantly shortened. By the way, carry the Otter board! - The time required for 414'C to finish wrapping the reins and net penn 1 after securing the reins to the base is approximately 3
However, according to the present invention, it was possible to shorten the time to about 10 minutes.
