Abstract

The invention aims to simplify the process of pouring the catch from the trawl during its lifting and reducing damage to the catch. The device for lifting the trawl to the stern-trawling vessels and pouring the catch out of it contains a hopper 1 for fish with a hatch 2, a trawl winch 3 for sampling warps 4 trawl 5 and a means for everting the trawl, consisting of a pipe (T) 6, cantilevered on the base 16 between the slip 8 and the hatch 2 and the warp 4 and the trawl 5 with the catch, and also two mechanisms for pulling the toppers on the outer side of the T 6. Each mechanism contains one driving and two driven rollers, between which trawl tops 5 upon selection ke. The end of T 6, located above the hatch 2, has an outwardly facing flap 15. Moving the trawl inside T 6 and pulling the toppers with a net canvas on its outer surface ensures the safety of the fish, as it is not under pressure. 6 Il.

FIG. /

The invention relates to industrial fishing, in particular, to devices for lifting a trawl to ships of stern trawling and pouring catches from it.

The purpose of the invention is to simplify the process of pouring the catch and reducing its damage.

When using the proposed device, the safety of the casting process is improved, and operations for connecting and detaching the elements of the trawl accessories during the sampling and pouring of the catch are eliminated.

FIG. 1 shows a device, a longitudinal section; in fig. 2 - the same, top view; in fig. 3 - placement of the nodes of the mechanism for pulling trawlers to the trawl, longitudinal section; in fig. 4 shows the position of the device during the interaction of the mechanism for pulling the tenants with the trawls; in fig. 5 - the same, at the location of the trawl with the catch on the slip of the vessel; in fig. 6 - the same, with the catch completely poured from the trawl.

A device for lifting the trawl to the stern trawling vessels and pouring the catch out of it consists (Fig. 1 and 2) of a tank 1 for fish with a hatch 2, a trawl winch 3 for selecting warp 4 4 of the trawl 5 and means for turning the latter, which contains a pipe 6 for skipping trawl 5 with catch and warpers 4, and two mechanisms 7 for pulling trawlers to trawl 5.

The pipe 6 is cantilevered on the deck of the vessel between the slip 8 and the hatch 2 of the bunker 1 for the fish so that its output end is located above the latter.

The Weer 4, stored in the drums of the winch 3, are connected by means of cables 9 and locks 10 of the coupling (brackets or hooks) to the trawl 5.

Mechanisms 7 for pulling trawlers to the trawl are located on the outside of the pipe 6. Each mechanism 7 (Fig. 3) consists of a leading roller 11 rotatable mounted on the base 12 mounted on the deck of the vessel, and. two driven rollers 13 and 14, which are fixed to the pipe 6 with their bases, while the roller 14 of each mechanism 7 is mounted directly at the output end of the pipe 6, and the edge of the latter has a rounded flange 15 facing outward, while the edge of the flanging 15 matches the working surface rollers 14.

The cantilever fastening of the tube 6 allows the catch to be poured into the hatch 2 and to pick up the net trawl web that has been released from the catch onto the outer surface of the tube 6.

The pipe 6 may have a round or square section, and for its console

The fasteners use a base 16 located at the upper end of the slip 8.

The device works as follows. After filling the trawl shed 5 catches

By means of the trawl winch 3, Vaer 4 and cables 9 are wound on its drums until locks 10 approach the disconnection to the screening 15 of the pipe 6, the locks 10 are disconnected, and the steamers 17 are placed in the mechanisms 7 on the driven rollers 13 and 14 and pressed by the driving roller 11. By rotating the drive roller 11 (the roller drive is not shown), the trawl mouth 5 is moved, and then the entire trawl cage along the outer surface of the pipe 6, as a result of which the selected net fabric trawl cage collects on the cantilever part of the pipe, and the trawl curl, filled with catch moving inside the tube and turning out on its flange 15, it is freed from the catch, which through the hatch 2 enters the bunker 1 for fish.

By reaching the end of the crawl flail of the flange 15 of the tube 6, the catch is finished pouring from the trawl 5 into the hopper 1 for the fishing vessel fish. Casting the catch with the use of the proposed device is simplified, since it is not associated with dragging the end of the trailing net inside the latter and through the entrance and exit hatches of the fish bin as in the known device, the fish is not injured and does not deteriorate, since it is turned in the bow. It does not crush, but pours out of the trawl at the position it occupies in the process of fishing.

When the clump is filled with a catch, the black cloth takes a square shape, and at the curved edge after

5 of the cage from catching fish takes the form of a rhombus, which increases the diameter of the cage and ensures its movement along the outer surface of the pipe 6.

Launching a trawl into water for later

Trawling is carried out by reversing it using, for example, a known device of the type of floating core attached to the outer end of the hook.
