Description

[Detailed Description of the Invention] The present invention relates to a powered seine hauling device for an outboard motor boat.

Conventionally, in one-man fishing boats, an outboard motor has been used as the driving power engine, and drift nets or drag nets have been pulled up manually. but,
Despite the aging of the fishermen population, without younger successors, they have reached their physical limits to pull up the seine by hand, and for this reason even small fishing boats are forced to use power. There was a strong desire for the emergence of a seine hauling device.

The present invention was developed in view of the above situation, and the object is to provide a power-powered seine hauling device for outboard motor boats that has a small capacity, a simple structure, requires almost no labor, is easy to operate, and improves efficiency. This is the purpose.

The above-mentioned drum for hoisting a hand net such as a drift net or a drag net, the above-mentioned speed reducer and a clutch disposed between the above-mentioned drum and intermittent transmission of power, and the above-mentioned rotatable internal combustion engine can be moved to any rotational position on the bottom of the ship. A foot-operated position fixing plate is provided.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a power-type seine hauling device for an outboard motor boat according to the present invention will be described below with reference to FIGS. 1 and 2.
FIG. 1 is a plan view of a small boat equipped with an outboard motor to which a powered seine hauling device is attached, and FIG. 2 is an enlarged cross-sectional view of the main part of FIG. 1. In the figure, 1 is a small boat for one person, an outboard motor (engine) 2 is attached to the stern of the small boat 1, and a propeller 3 driven by the outboard motor 2 is attached. Movement is via an outboard motor 2. On the front side of the center of the small boat 1 in the direction of travel, there is a box body 5 with a small capacity internal combustion engine 4 built in the lower part and a base 12 on the bottom 6, which is covered and safely formed so that nets etc. do not get caught. A thrust bearing 7 is interposed between the shaft and the shaft, and the shaft is rotatably mounted as shown by the arrow in FIG. A reducer 8 is fixed on the reducer base 20 fixed to the box 5 in the upper part of the box 5, and the power of the internal combustion engine 4 is transmitted to the reducer 8 via a belt 9 and then decelerated. The drum 11 is driven through the drive shaft 10 at a speed of about 70 rpm. Further, the internal combustion engine 4 is disposed at a lower portion close to the bottom 6 on the center line of the starboard and portboard of the small boat 1, and a drum 11 is disposed above coaxially with the reduction gear 8. This is done by placing the internal combustion engine 4 as low as possible to lower the center of gravity of the small boat 1 to prevent it from capsizing, and by arranging the drum 11 upwards so that when the seine net 16 (to be described later) is hoisted up, the seine net is either starboard or port. This is to reduce contact with the upper edge of.

The drum drive shaft 10 has a bearing 19 fixed on a bearing support base 13 protruding from the side of the box 5.
19, and the drum 11 is configured to be rotatable integrally with the internal combustion engine 4 relative to the small boat 1. Furthermore, the condition of small boat 1 at sea 18 is as follows:
Although the direction is always changed and moved by the direction of the waves and the wind, the seine net 16 is always taken up by the drum 11 at a position almost perpendicular to the axis of the drum 11 (hereinafter referred to as "perpendicular"). It works automatically like this. That is, the seine net 16 is connected to the drum 1.
1, when the axis of the drum 11 is formed to be freely displaceable, the hand net 16
A force that tends to make the winding direction and the drum axis perpendicular to each other naturally acts on each of the drums 11 and 11. A clutch 14 is attached to the drum drive shaft 10 between the reducer 8 and the drum 11, and is adapted to intermittent the power transmitted from the reducer 8 to the drum 11. 15 is box body 5
The small boat 1 of the box body 5 can be fixed by stepping on the position fixing plate 15 with part of the foot of the operator (fisherman) standing on the bottom 6 of the boat.
The rotational position can be fixed. That is, the position fixing plate 15, the bottom 6, and the like form a means for fixing the horizontal rotation of the internal combustion engine 4 to an arbitrary position on the bottom 6. The seine net 16 hoisted onto the drum 11 is wound approximately 1.5 times around the body of the drum 11, and then is always pulled and held by the operator's hand so that it is organized and deposited in a circular shape at a sorting position 17. It's summery. The drum portion of the drum 11 around which the seine net 16 is wound is coated with rubber around the outer periphery to prevent slippage between the drum and the seine net 16. The reason why the position fixing plate 15 is provided is to stabilize the hoisting operation when hoisting the manual hoist 16. That is, the seine net 16
As mentioned above, in the natural state, the winding direction of the hand net 16 is automatically at a position perpendicular to the axis of the drum 11, but if the winding direction of the hand net 16 and the axis of the drum are fixed at a position orthogonal to each other, If hoisting is performed without doing so, the small boat 1 will continue to be rocked unsteadily by the waves, making it difficult to hoist stably. Therefore, in order to prevent this, the small boat 1 is sewn with a seine net 1.
6. Fix it in the lifting direction and perform hoisting work. Then, it is fixed until the lifting direction is tilted from the orthogonal position and reaches an unfavorable angular position, and when it reaches an unfavorable angular position, it is released and returned to the orthogonal position and fixed again to perform hoisting. and repeat this.

When hoisting a seine net 16 using this power-type seine-hauling device, the outboard motor 2 is stopped, the clutch 14 is disengaged, and the internal combustion engine 4 is started. 1,5 seine net 16
Hold the rolled end in your hand and fry. In this case, it must be pulled up slowly. The reason for this is that if the fish are pulled up too quickly and forcefully, the fish will fall out of the net and cannot be caught. When hoisting is started, the axis of the drum 11 is at a position perpendicular to the hoisting direction of the seine net 16. Then, by stepping on the position fixing plate 15 with a foot, the drum 11 is fixed to the small boat 1, and the clutch 14 is engaged to drive the drum 11 to rotate and wind it up. The seine nets 16 wound around the drum 11 are sequentially stacked and arranged in an annular manner at a sorting position 17 as shown in FIG. In this case, the seine net 16 can be hoisted up without slipping on the drum 11 by constantly tugging (pulling) it lightly. When the seine net 16 is reeled in, and if a fish is caught in the net, the clutch 14
The fish are removed from the seine net 16 and stored in a cage on the bottom of the boat. That is, unless the fish are removed from the seine net 16 before the drum 11, the fish will be damaged. If they are not kept alive, the value of the product will be significantly reduced when sold. If the winding direction of the seine net 16 deviates from the position perpendicular to the axis of the drum 11 due to the direction of waves or wind, the position of the drum 11 can be adjusted by loosening the foot and releasing the position fixing plate 15. After that, the position fixing plate 15 is fixed and winding is performed at the right angle position. That is,
The drum 11 is perpendicular to the hoisting direction during hoisting of the seine net 16. When the small boat 1 moves and is about to deviate from the right angle, when the foot is removed from the position fixing plate 15, it will automatically become right angle. At this time, you can step on it again with your foot. That is, by stepping on or removing the position fixing plate 15 with a foot, the drum 11 can be controlled to be fixed or rotatable instantly. Therefore, normally all that is required is to lightly pull the seine net 16 and organize the wound seine net 16, and if the winding direction deviates from the position perpendicular to the axis of the drum 11, the position The work is simple and easy, and requires almost no effort. Moreover, the driving force for the drum 11 can be as small as conventionally done by the manual labor of a middle-aged man, and winding can be carried out efficiently.

The power-powered seine hauling device for outboard motor boats of this embodiment is constructed in this way, and has a small capacity and simple structure.The internal combustion engine, reducer, and belt are covered with a box, making it safe and inexpensive to manufacture. Easy to operate, no labor required
It is easy and efficient to reel in a dragnet. Since it is a small boat floating on the sea, it is shaken by the waves and wind and moves constantly, and the winding direction of the seine and the direction of the drum axis tend to deviate from the perpendicular state, but this is returned to the original perpendicular state. This is extremely simple and easy to do, so winding can always be carried out with high efficiency. Moreover, since it requires almost no labor, it is suitable for older and more experienced fishermen to carry out efficient fishing, and because they can cast a net two to three times wider than before, they can increase the amount of fish they catch. .

As described above, the powered seine hauling device for an outboard motor boat of the present invention has a small capacity and simple structure, requires almost no labor, is easy to operate, and has the effect of significantly improving efficiency.
