Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a net hauler device for fishing nets having fishing net work for fishing boats.

[Conventional technology]

In the conventional net hauler device, as shown in Fig. 4, a guide rail 11 is laid on the stern 10 of the purse seine fishing boat so as to fill the left and right sides of the port, and the net hauler device 12 mounted on the carriage is movable on the guide rail 11. It was installed. In the fishing net work, first, the net hauler device 12 is used to lift the fish net at the stern, and the fish net is narrowed while gradually pulling the fish net from the stern toward the shipowner using side rollers to perform the fishing net work. Was there.

[Problems to be solved by the invention]

However, this requires a worker to lift the nets on the side rollers, resulting in poor workability.

Therefore, the applicant has arranged a guide rail 13 for guiding the net hauler device 12 on the starboard side from the stern as shown in FIG. 5 so that the net hauler device 12 can be moved on the starboard side rear part to save labor. However, if the conventional hoisting net hauler device 12 is used as it is, there is a Boolean work 14 on the starboard side. There was a problem that was bad.

The present invention has been made in view of such circumstances, and an object thereof is to provide a net hauler device for a net with good operability.

[Means for solving problems]

A net hauler device for a net pursuing the above purpose has a bogie that moves on a guide rail, a tilting platform that is tiltably attached to the bogie, and a net hauler that is mounted on the tilting platform. In a net hauler device for nets, a sub-tilting stand is provided on the tilting stand to enable tilting in a direction opposite to the tilting direction of the tilting stand, and the net hauler is mounted on the sub-tilting stand. Is configured.

At least the starboard side of the guide rail is preferably laid here from the stern to the middle part of the starboard.

[Action]

According to the net hauler device for a net according to the present invention, since the sub-tilting table is provided on the tilting platform and the net hauler is placed on the sub-tilting table, the tilting range of the upper net hauler is increased. It is enlarged, which allows it to be moved outwards without colliding with the side boule work.

In particular, in the net hauler device for a net according to claim 2, since the starboard side is movable on the guide rail laid from the stern to the middle part,
As a result, it is possible to move from the stern toward the bow as the fishnet is rolled up.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention.

Here, FIG. 1 is a front view of a tilting net hauler device according to an embodiment of the present invention in a tilted state, FIG. 2 is a front view of the net hauler device for a fishing net in an upright state, and FIG. The side view and FIG. 4 are plan views showing a laid state of guide rails of the net hauler device for the net.

As shown in FIG. 1, FIG. 2 and FIG. 3, a net hauler device 15 for a net according to an embodiment of the present invention includes a carriage 17 traveling on a guide rail 16 and a rotation on the carriage 17. A tilt table 19 which is attached so as to be rotatable around a shaft 18, and the tilt table 19
The sub tilting table 21 is rotatably attached to the end of the sub tilting table 21 through a pin 20, and the net hauler 22 is mounted on the sub tilting table 21. These will be described in detail below.

The guide rail 16 is arranged so that the starboard side is directed from the stern toward the center of the ship, and the cart 17 having wheels 23 and 24 attached to the lower part thereof travels on the starboard side. Wheels 25 and 26 are provided on the side of the carriage 17 as shown in FIGS. 1 and 2,
Guide rail 28 mounted on the starboard side boule work 27
It is designed to prevent the cart 17 from falling over.

A pin row 29 in which a plurality of pins are arranged at a predetermined interval is arranged in the middle of the guide rail 16, and
A sprocket 31 driven by 30 meshes with the pin row 29 to move the carriage 17 forward or backward, and a brake mechanism 32 for holding the guide rail.
If necessary, the carriage 17 can be held in a predetermined position by rotating the handle 33.

The carriage 17 serves as the center of rotation of the tilting base 19 and is mounted on the tilting base 19.
A rotary shaft 18 to which is fixed is rotatably attached, and a rotary actuator 34 driven by a cylinder is provided at an end of the rotary shaft 18 to rotate the rotary shaft 18 by an appropriate angle. The tilting table 19 is tilted by a predetermined angle as shown in FIG.

A sub-tilt base 21 is attached to the inner end of the tilt base 19 via a pin 20.
A center trunnion type hydraulic cylinder 35 having a cylinder portion rotatably attached to the tilting table 19 is provided at the other end of the sub-tilting table 21. The structure is such that the sub-tilt table 21 can be lifted inward.

A net hauler 22 is mounted on the sub-tilt table 21, and the net hauler 22 is provided with a hydraulic motor 36 for turning so that the sub-tilt table 21 can be swung.

Therefore, when the net hauler device 15 for the net is used, the rotary actuator 34 is normally driven while the hydraulic cylinder 35 is contracted and the net hauler 22 is upright as shown in FIG. As shown by the chain double-dashed line in FIG. 2, it is stored in the stern in a state of being laid sideways. When it is used, the rotary actuator 34 is driven to stand upright as shown in FIG. Hydraulic motor in this state
36 is used to rotate the net hauler 22 at an appropriate angle, but when it is brought closer to the starboard side boule work 27, the hydraulic cylinder 35 is once extended to tilt the sub tilting base 21 inward. The rotary actuator
Operate 34 and tilt the tilting base 19 to the opposite side,
21, that is, the lower end of the net hauler 22 can be extended further to the side, which improves the fishing net work.

In this embodiment, the bottom of the net hauler 22 is attached to the sub-tilt table 21 and tilted.
The present invention is applicable even when the bottom of the net holar 22 is integrated with the net hauler 22.

Further, in this embodiment, the guide rails are installed parallel to the boule work, but as shown in FIG. 5, the present invention is applied even when the guide rails are orthogonal to each other. In this case, the stern is used. The present invention is applicable regardless of whether the guide rail together with the guide rail is moved orthogonally or the guide rail is smoothly bent so that the carriage can pass on the guide rail.

[Effect of device]

As apparent from the above description, the net hauler device for a net according to the present invention is provided with a sub-tilting table on the tilting table, which can be tilted in the direction opposite to the tilting direction of the tilting table. It is possible to raise the other end of the net hauler mounted on the tilting table, which allows the net hauler to be moved without colliding with the blue work, which improves the operability of the net lifting work.

In particular, as described in claim 2, even when the net hauler is run from the stern to the starboard side, the net can be carried out without any trouble, which eliminates the need for manpower in the vicinity of the side rollers, which greatly saves labor. It has become possible to contribute.
