Description

TECHNICAL FIELD The present invention relates to a rotation assisting device for a kelp collecting instrument, and more particularly to a rotation assisting device for a sampling instrument equipped with a buttock used when collecting kelp from the seabed.

In general, to collect natural kelp that grows on the seabed, it is attached to the tip side of the salmon and is used using fishing equipment called so-called makka. There are several things that differ. FIG. 11 is a conceptual diagram in the case of collecting kelp using Shiba Makka. Shiba Makka 100 in FIG. 11 is composed of ridges 102 and locking portions 104, and is performed using Makka 100. To collect natural kelp, we can cut the kelp root from the seabed by rotating and twisting the kite 102 in a state where the kelp is hooked on the bifurcated locking portion 104 and then raising the kite on the ship. This is done by using a winch or the like.

Such seafloor natural kelp collection work must be carried out on a ship that swings back and forth, left and right, up and down by waves, and the distance from the ship to the seabed may exceed 10 m. It was forced to carry out harsh work that was dangerous and heavy labor for the workers.

Therefore, various techniques have been proposed in the past in order to reduce the labor for collecting kelp.
As an example thereof, a device described in a registered utility model No. 3067201 (actual application No. 11-7689 to Patent Document 1) is known. The device described in the publication has a plurality of plastic collecting rod bodies, characterized by the structure of the joint when these collecting rods are connected to each other, and the outer shape of the collecting rod is a polygonal shape. It is said that it is possible to smoothly perform a twisting operation for separating the roots of the head.

Further, in the invention described in Japanese Patent Application Laid-Open No. 10-42656 (Patent Document 2), a conical surface of a pair of drum members formed in a conical shape is installed so as to face each other, and a V-shape or U formed on the facing surfaces. It is configured to transmit the lifting force and rotational force (torsion) simultaneously to the kite by fitting the sampling kite that collects kelp into the letter-shaped lifting groove. Is entangled so as not to fall off.
In the invention described in Japanese Utility Model Laid-Open No. 5-43818 (Patent Document 3), a V-shaped lifting groove is formed on the outer periphery of the drum, and a sampling rod is fitted into the lifting groove in the lifting groove. Thus, the drum is rotated by a hydraulic motor or the like to facilitate the lifting operation.

Registered Utility Model No. 30672201 Japanese Patent Laid-Open No. 10-42656 Japanese Utility Model Publication No. 5-43818

However, the collecting rod such as seaweed described in Patent Document 1 described above is intended to facilitate the twisting operation when cutting the seaweed, but the twisting operation itself must be performed manually. The burden on fishermen remains large.

In addition, the lifting device described in Patent Document 2 can be lifted while turning the collection basket, and this can prevent the kelp from falling off. It was not possible to add only the rotational force alone to the collection basket. Therefore, the twisting operation for cutting kelp must be performed by human power, and the burden on fishermen is still large.
Furthermore, although the lifting device described in Patent Document 3 can reduce the lifting operation, the twisting operation for cutting the kelp still needs to be performed manually.

The present invention has been made in view of such circumstances, and cutting and twisting work of kelp using a kelp collecting tool is also performed on a ship that is swung back and forth or left and right (pitch, roll, yaw) due to waves. An object of the present invention is to provide a rotation assist device for a kelp sampling instrument that can be safely and efficiently performed and can simultaneously reduce the labor required for lifting the kelp sampling instrument (mecca).

The invention according to claim 1 is a rotation assisting device for a kelp sampling instrument comprising a driving means and a rotating part having first and second rollers that are driven to rotate in the same direction by the driving means. The gap formed between the first and second rollers is an insertion part of the kelp sampling device, and the insertion part is arranged so as to face the sea side during use, and the gap of the narrowest part of the insertion part is The first and second rollers are installed so as to be slightly narrower than the outer diameter of the buttocks in the kelp sampling device, and the buttocks of the kelp sampling device are positioned in the longitudinal direction in the insertion portion, The outer peripheral surfaces of the first and second rollers are brought into contact with the flange, whereby a rotational force is applied to the flange from the first and second rollers.

A second aspect of the present invention is characterized in that, in the first aspect, the torque transmission surface that contacts the outer peripheral portion of the kelp collecting device in the roller and applies a rotational force is formed in a curved surface shape.

A third aspect of the present invention is characterized in that, in the first or second aspect, a third roller is disposed on the back side of the insertion portion with respect to the first and second rollers disposed adjacent to each other. It is said.

According to a fourth aspect of the present invention, in any one of the first to third aspects, the roller is rotationally driven by the driving means in the same direction and the same peripheral speed. .

A fifth aspect of the present invention is the above-described third or fourth aspect, wherein the line segment connecting the rotation axes of the two rollers of the first, second, and third rollers is from the bow of the ship to the stern edge. On the other hand, the two rollers are installed so as to be substantially parallel to each other.

  Invention of Claim 6 is equipped with the lifting part which is installed adjacent to the said rotation part in any one of said 1st-4th, and acts a lifting force with respect to a kelp sampling instrument. It is characterized by.

According to the present invention, when a fisherman (user of the device) performs a kombu collecting operation on a ship, the user himself / herself presses the buttock against the torque transmission surface of each roller, thereby rotating torque to the heel. Therefore, the transmission of torque can be immediately executed and interrupted at the discretion of the user, and the kombu collecting operation can be performed safely and efficiently.
In addition to the rotating part that assists in collecting kombu, a lifting part that adds lifting power to the heel part is installed adjacent to it, so it is possible to reduce the labor required for lifting the kelp collecting tool Become.

Hereinafter, a preferred embodiment of a rotation assisting device for a kelp collecting device according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic perspective view of an embodiment of a rotation assist device, FIG. 2 is a plan view, FIG. 3 is a front view, FIG. 4 is a side view, and FIG. 5 is a relationship between the rotation assist device of this embodiment and a kelp collecting tool. FIG. 6 is a schematic explanatory view showing a case where the rotation assist device of the present embodiment is installed on the freeboard of a ship.

As shown in these drawings, the rotation assisting device 10 of the present embodiment is composed of a rotating part 12, a support frame 14, and the like. Among these, the rotating part 12 is placed on the support frame 14. As shown in FIGS. 4 and 6, the rotation assist device 10 is fastened by a pair of flat plate-like fixing means 15 provided on the support frame 14 in a state where the ship's freeboard 1 is sandwiched. It can be done.

As shown in FIG. 1, the rotating unit 12 includes first to third rollers 16, 18, 20, an upper plate 22 and a lower plate 24, a motor and a speed reduction mechanism, a drive unit 26 such as an inverter, and the like. .

The first to third rollers 16, 18, and 20 are pivotally supported between the upper plate 22 and the lower plate 24 so as to be horizontally rotatable, and are transmitted from the driving means 26 via a plurality of gears, chains, or belts. Rotating at the same circumferential speed with the same driving speed.
The outer peripheral portions of the first to third rollers 16, 18, and 20 are rubber torque transmission surfaces 16A, 18A, and 20A that are formed into curved surfaces.
The rubber forming these torque transmission surfaces 16A, 18A, and 20A may be processed with slits, dimples, etc. in order to increase the friction coefficient, or for each of the first to third rollers 16, 18, and 20. Alternatively, rubbers having different characteristics (hardness, weather resistance) such as a friction coefficient, or soft and rigid materials may be used.

  As shown in FIGS. 1 and 2, the rotation assisting device 10 of the present embodiment is an insertion formed between the first and second rollers 16 and 18 when installed on a fishing boat, with reference to the shipboard. The portion 30 is arranged facing the sea side direction, and the third roller 20 is installed on the back side (the ship upper side) of the first and second rollers 16 and 18.

As shown in FIG. 2, the dimension L of the gap formed between the first and second rollers 16, 18 is slightly narrower than the maximum outer diameter of the flange 50 </ b> A of the kelp collecting device 50. It is desirable to set the interval.
As described above, the gap L is set at a slightly narrower interval than the maximum outer diameter of the flange 50A, and the flange 50A of the kelp sampling device 50 is positioned at the insertion portion 30 between the rollers 16 and 18. This is because the rotational force from each of the rollers 16 and 18 is more easily transmitted.

In other words, when twisting the seaweed growing on the seabed to the tip (mecca) of the sampling instrument 50 and twisting the buttock 50A, a rotational force is applied to the outer periphery to assist (assist) the twisting operation. Since it is effective for the rollers 16 and 18 to improve the adhesion between the kelp collecting device 50 and the collar portion 50A, the dimensions are set as described above. As the cross-sectional shape of the flange portion 50A, a circular shape or a polygonal shape such as a regular hexagon is used.

  On the other hand, when inserting the collar portion 50A of the kelp collection device 50 into the insertion portion 30 between the three rollers 16, 18, 20, 20, the collection device 50 is tilted as shown in FIGS. The operation becomes easy. That is, the torque transmission surfaces 16A, 18A, and 20A on the outer peripheral portions of the rollers 16, 18, and 20 are formed in a curved surface shape (R shape) and have elasticity, and therefore, by tilting the flange portion 50A, It becomes easy to insert into the gap of the insertion portion 30 set at a smaller interval than the maximum outer diameter of the flange portion 50A. As a result, both the ease of use as an auxiliary device and the two points of ensuring the necessary rotational force by the frictional force of the roller are achieved.

When collecting the kelp using the kelp sampling device 50, the operation is performed on a ship that is swayed by waves, and the position of the root of the kelp to be collected from the seabed is constant.
For this reason, it is practically difficult to keep the kelp sampling device 50 at a constant angle and at a constant height during work on the ship. The fishery worker, when collecting kelp, grasps the kelp collecting device 50 and basically performs the kombu collecting work while twisting the buttock 50A. However, the torsional motion on a rocking ship places a heavy burden on fishermen.

In consideration of such a situation, the rotation assisting device 10 of the present embodiment employs a configuration in which a rotational force can be easily applied to the kelp sampling instrument 50. That is, when the kelp sampling device 50 is nearly vertical, the rotational torque is transmitted mainly by the frictional force generated by the contact between the outermost peripheral portions of the rollers 16, 18, and 20 and the outer peripheral surface of the flange portion 50A. .
On the other hand, when the waves are rough and the rocking (pitch, roll, yaw) of the ship is large, the kelp sampling device 50 also changes its inclination and height with the ship. It becomes difficult to hold on.

Therefore, in the rotation assisting device 10 according to the present embodiment, the entire torque transmission surfaces 16A, 18A, and 20A formed in a curved surface among the rollers 16, 18, and 20 are used with respect to the outer peripheral surface of the flange portion 50A. And configured to transmit rotational torque.
Thereby, while responding to the swinging of the ship and the inclination / up-and-down movement of the groin 50A, a rotational force is applied to the groin 50A to reduce the burden on the fishermen.
That is, with respect to the vertical movement of the buttock 50A, the user operates the buttock 50A of the sampling device 50 so as to be positioned in the insertion portion 30, and applies to each of the rollers 16, 18, and 20. By adjusting the pressing force, rotational torque is transmitted while corresponding to the vertical movement of the flange 50A.

Further, with respect to the inclination of the flange 50A, the torque transmission surfaces 16A, 18A, and 20A of the rollers 16, 18, and 20 are formed in a curved surface, so that the front / rear and left / right inclinations of the flange 50A are dealt with. It is possible to transmit the rotational force while. That is, in order to steadily transmit the rotational force from the rollers 16, 18, and 20 to the flange portion 50A, it is important that the torque transmission surfaces 16A, 18A, and 20A are formed into curved surfaces. With this configuration, even when the flange portion 50A is inclined, the outer peripheral surface of the flange portion 50A can be brought into contact with any one of the three torque transmission surfaces 16A, 18A, and 20A, and the rotational force can be applied to the flange portion 50A. It is possible to reduce the labor of fishermen by adding them to the fishery.

7 and 8 are explanatory views showing the relationship between the rotating unit 12 and the kelp collecting device 50 during use. For example, in FIG. 7, the flange portion 50 </ b> A of the kelp collecting device 50 comes into contact with the torque transmission surface 16 </ b> A of the lower portion of the first roller 16 and the torque transmission surface 18 </ b> A of the upper portion of the second roller 18. , Rotational force is added.
Further, in FIG. 8, a rotational force is applied to the flange 50A in contact with the torque transmission surface 16A at the center of the first roller 16 and the torque transmission surface 18A of the third roller 20. .

Thus, according to the rotation assistance tool 10 which concerns on this embodiment, when collecting the seabed kelp using the kelp sampling instrument 50, a fishery worker basically operates the buttock 50A. When the twisting operation is performed, a rotational force is applied to the flange portion 50A. Thereby, even in the case of work on a swaying ship, it is helpful when performing the twisting operation of the buttock 50A, and the burden on the fishermen can be greatly reduced.

Moreover, in this embodiment, using the rotational force obtained by a fishery worker (user) pressing the heel part 50A against the torque transmission surfaces 16A, 18A, 20A of the rollers 16, 18, 20, Since the flange portion 50A is twisted, the assist force necessary for the rotation can be appropriately adjusted by the user according to the situation.
In other words, in a situation where the tip of the buttock 50A (the mucka portion) is in contact with the seabed, when the buttock 50A is firmly fixed, the buttock 50A and the auxiliary device 10 are attached to the heel part 50A and the auxiliary device 10 as the ship swings. There is a risk of overloading and damaging one of them.
For this reason, in the rotation assistance apparatus 10 of this embodiment, about transmission of the rotational force to the collar part 50A, the user himself dares to press the collar part 50A against each of the rollers 16, 18, 20 to obtain the assist force. Adopted. According to this, it is possible to execute or interrupt the application of the assist force immediately at the intention of the user, or to adjust the strength of the assist force, and the load generated on the sampling instrument 50 and the auxiliary device 10 can be kept to a minimum. Therefore, it is possible to avoid unexpected situations such as damage.

FIG. 9 is a schematic plan view showing a rotation assisting device for a kelp collecting instrument according to another embodiment, and FIG. 10 is a schematic explanatory diagram showing a work situation by the rotation assisting device. The rotation assisting device 40 shown in FIG. 9 is different from the assisting device 10 described above in that a roller winch (lifting portion) 42 for lifting the kelp collecting device 50 is disposed adjacently.
Here, members similar to those of the rotation assisting tool 10 described above are assigned the same reference numerals, and descriptions thereof are omitted.

In the rotation auxiliary device 40 of this embodiment, when the line segment connecting the rotation axes of the two rollers 16, 20 among the first to third rollers 16, 18, 20 is an XX line, the XX The line is arranged substantially parallel to the ship's freeboard 1 and a roller winch 42 is provided adjacent to the side of the first roller 16.
In other words, the line XX line connecting the rotation axes of the two rollers 16 and 20 is arranged so as to be substantially parallel to the stern edge of the ship from the bow of the freeboard of the ship. A roller winch 42 is installed adjacent to the side.
In addition, the rotation assisting device 40 may be configured such that the rotating unit including the first to third rollers 16, 18, and 20 and the lifting unit 42 may be integrated, or may be installed as separate members. good.

The low-row inch 42 is provided with a winch portion 44 having a V-shaped groove, and the winch portion 44 is rotationally driven by a motor, a gear, a chain, a belt, and a rotary joint (not shown).
When pulling up the kelp collecting device 50, as shown in FIG. 10, the upward force is applied by pressing the hook portion 50A of the kelp collecting device 50 against the groove 44A of the winch portion 44, Together with the collected kelp 46, the buttock 50A can be lifted onto the ship.

In the rotation assisting device 40 of the present embodiment, a roller winch 42 that performs a lifting operation in addition to the rotation / twisting operation of the kelp collecting device 50 is disposed in the vicinity of the side of the first roller 16.
Further, since the first roller 16 rotates counterclockwise, after completion of the kelp root cutting operation, the collar portion 50A of the kelp sampling device 50 is removed from the insertion portion 30, and the rotational force of the first roller 16 is removed. Can be quickly moved to the roller winch 42 side. Thereby, after the rotation / twisting work, it is possible to quickly shift to the next work of lifting the sampling device 50, and the labor required for the kelp sampling work can be greatly reduced.

  As described above, according to the rotation assisting tool for the kelp collecting device according to the present invention, when performing the collecting work of kelp, the labor of the fishermen can be greatly reduced, and the onboard ship with a large swing It has the effect of making it possible to perform safe and efficient harvesting of kelp in Japan.
