Description

112

The invention relates to commercial fishing, in particular to trawling fishing gear for fishing trawling vessels.

The aim of the invention is to increase reliability in operation by ensuring that the catch is injected by inverting the trawl.

FIG. shows a trawl for fishing marine objects, a general view; figure 2 - the same, when placing the beginning of the Kutka above the receiving hatch of the bunker; figure 3 - the same, at the beginning of the fishing out; Fig. 4 - the same, after the end of the catch insertion.

The trawl contains a net bag 1 with a kutk 2, the front part of the latter is equipped with catfish 3 with rings 4. Cables 5 are reinforced along the leading edge of the net-bag 1 and have rings 6. Vaera 7 are connected by free ends of cables 5. Rope 8 is inserted at one end the inside of the trawl and is connected to the tie-in 2. The second end of the rope 8 is divided into two branches 9 and 10, each of which can be disconnected by means of the hook 11 through the ring 4 with skull 3 and through the hook 1 2 with the ring 6 of the corresponding Cable 5. K an end of the exhaust cable 13 is connected to the end of the cage 2 from the outside The free end of it is connected to one of the cables 5 with the possibility of disconnection through the hook 14 and the ring 6. The catch is inserted into the hatch 15, and the turned out knot is directed into the hatch 16.

Trawl works as follows.

In the process of trawling, the towing of the net bag is carried out for the wire 7 and the cables 5, while the rope 8 placed inside the net bag 1 is connected via hooks 11 to the rings 4 and 3 and hooks 12 to the rings 6 of the cable 5, the exhaust cable 13 connected hook 14 with rings 6.

In order to remove the trawl, the catch of the trawl is pulled down to the fishing ship of the stern trawl, and the ring 6 is attached to its stern, and the hooks 12 detach from them and

unified with a ship trawl winch cable (not shown).

Before pouring the catch through the ship's trawl winch, the branches 9 and 10 of the rope pull-in. 8, 3 p. 3 are pulled to the ship's receiving hatch 15 and fixed to 3 from the hatch 15 by means of rings 4, detached from hooks 11 (Fig. ).

Catching of the catch is done by tensioning the trailing ship's winch of the rope 8 and moving the end of the knot 2 inside the latter to the hatch 15 (Fig. 3).

The inverted crook 2 is directed to the ship's exit hatch 16. With the trawl completely turned out, the entire catch from the trawl is unloaded into the hatch 15.

After the catch is unloaded, the hook 14 is disconnected from the ring 6 and connected either with a trawl lowering device (not shown) or with a ship's stern winch and, pulling the pull rope 13, fold the trawl in reverse order and lower into the water for later sweeping away.

Thus, the invention makes it possible to increase the efficiency of using the trawl for catching marine organisms by providing catcher insertion without the use of special means for lifting the hut over the bunker hatch, to avoid multiple laborious processes of trailing the trawl, traumatizing the fish with the lines and squeezing it when lifting.

The presence of a cable from the outside of the ramp, with one end attached to the end of the hook, and the other to one of the cables with the possibility of disconnection, and the presence of a rope, one end of which is inserted into the trawl and connected to the hook, the second is divided into two branches, each which, with the possibility of disconnection, is connected to the catches and the corresponding cable, it provides an increase in the reliability in operation by inserting the catch due to the inversion of the trawl. Since the height of the fish layer being inserted is insignificant at the same time, and at the beginning of turning the crotch expands in cross section, the fish move freely to the trawl mouth without injury.
