Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kelp collecting rod and a rope pulling apparatus suitable for use in a natural kelp collecting area for labor saving of the collecting work.

[0002]

2. Description of the Related Art In a natural kelp production area (especially in Hokkaido), conventional fishing methods can be roughly classified as follows. Hereinafter, an example will be described.

(1) Sniffing—This is a fishing method used to collect kelp that is densely grown in a relatively shallow place. Anchors before and after the ship so that the tide is received from the bow.
A fishing method in which a shaped wooden or metal key is fixed to the tip of a long handle, and the kelp that is flowing sideways due to the tidal current is pulled and pulled out by hand. Especially in the eastern district.

(2) Sharp harvesting This is done by anchoring when the tide is fast or the wind is strong, stabilizing the boat, harvesting kelp, and using the right foot without the anchor when the sea is calm. This is a fishing method in which the position of the boat is adjusted while paddle is being performed, and the kelp is sampled while watching the kelp on the seabed with peep glasses.

(3) Twisting: a fishing method used in places where it is difficult to snatch or bite in relatively deep water, and called a maca at the tip of a kelp collecting rod (made of wood and FRP). A method in which the tool is fixed, the kelp collecting rod is rotated (twisted), and the kelp is entangled with this maca and twisted from the rock surface. This is the most popular fishing method among kelp fishing.

[0006] (4) Macchi-pulling (also known as rope-pushing fishing). Furthermore, fishing methods used in deep water and where tides are tight. Usually, a chain of about 1m is connected to two iron keys, and a rope is tied to this. It is used in offshore harvesting and later in the fishing season, but has the disadvantage of damaging kelp. In some parts of the country, four-claw hooks are used to catch kelp sinking to the seabed.

[0007] The above four sampling methods are still in use today, and all of them are actually operated manually.

[0008]

[Problem to be Solved by the Invention] Among the above-mentioned methods, the most popular method of torsion fishing with a kelp fishing rod is that it is often used at a deep water source, so that kelp that is firmly settled on rocks is used. It is a repetition of the work of pulling up the rod and taking it into the ship, in addition to the labor of twisting it. Therefore, it is extremely hard work to collect a full kelp on board.

[0009] The kelp sampling boat is usually a relatively small boat equipped with an outboard motor, and is usually operated by two people. There is a tide in the sea, and when you arrive at the kelp fishing ground, one person controls the turret and holds the direction and position of the ship, while the other operates the kelp rod to collect kelp.

[0010] By repeating the twisting and unloading of the kelp rod, when the ship is full, the ship returns to the dock and discharges the collected kelp to land. The emptied boat is returned to the kelp fishing ground again, and the same sampling is performed.

A fixed operating time is defined as a rule for these operations, and it is possible to freely collect samples within the range of time. However, on favorable days, when the weather is good, the wind is small, and the waves are small, At present, all fishermen are forced to work hard on hard days when they can operate.

When collecting kelp on a rock, the kelp collecting rod is usually twisted to the right, and the kelp is tangled with the kelp collecting rod and twisted. Therefore, when lifting the kelp fishing rod, if the kelp fishing rod is not turned to the right or care is taken so that the kelp does not come off, the kelp will come off from the kelp fishing rod and harvesting will not be possible. There is a fear. If the kelp collecting rod is given a rotation when it is lifted, more labor is imposed on the worker, and there is a problem that the working efficiency is deteriorated.

In order to solve the above-mentioned problem, there is a natural kelp collecting rod lifting device in which a natural kelp collecting rod is held in a V-shaped groove of a movable rotary drum so that the natural kelp collecting rod can be easily pulled up. (Japanese Utility Model Laid-Open No. 5-43818)
In this lifting device, a steering wheel for pressing a rod is disposed above the V-shaped groove of the rotating drum, and one drum component of the rotating drum is attached to one end of the power rotating horizontal shaft of the rotating drum on the other side. There is a problem in that the structure is complicated because the resilient device that presses against the drum component is provided.

The present invention has been made in view of this point, and has a simple structure, a clockwise rotation of a kelp collecting rod, a labor saving in kelp collecting work, a reduction in labor, and an aging fishery. It is an object of the present invention to provide a kelp extracting rod and a rope pulling device for improving the kelp extracting operation, including measures for the elderly.

[0015]

Means for Solving the Problems As means for solving the above problems, a kelp sampling rod and a rope pulling device according to the present invention are provided with a tapered cross-sectionally conical member having elasticity on a disk. A pair of guide drum members are formed by fixing the sides to form a drum member, two of the drum members, and the conical members being opposed to each other to form a pair of guide drum members. The rotating cylindrical horizontal shaft member is fixed to one side of the rotating cylindrical horizontal shaft member and the disk on one side, and the rotating cylindrical horizontal shaft member is mounted on the other side of the rotating cylindrical horizontal shaft member. A smaller diameter threaded cylindrical member is fixed via the disk on the other side to form a rotary drum, and the rotary drum is opened radially in the rotating cylindrical horizontal shaft member and the opposing surface of the conical member. A U-shaped lifting groove is formed, and the drainage groove is in contact with the lifting groove.
A groove plate is provided , the rotary cylindrical horizontal shaft member is connected to a rotary output shaft of a motor, and a mounting base for mounting the rotary drum on a kelp sampling boat is provided.

[0016]

[Function] Since the present invention is configured as described above,
When hoisting kelp with a kelp collecting rod, attach a lifting device to the port of the kelp sampling boat, push the kelp collecting rod with the kelp wound into the lifting groove of the rotating drum of the lifting device, and push it together with the kelp collecting rod. Withdraw the kelp on the kelp sampling boat.

That is, since the rotating drum is rotating from the sea side to the ship side, if the kelp sampling rod is pushed into the lifting groove opened in the radial direction, the lifting groove is made of an elastic material such as rubber and parallel. Due to the two sides, the kelp fishing rod is pulled up toward the front without being slipped, and at the same time, is drawn into the bottom of the lifting groove and bitten more and more.

When the kelp rod is sufficiently bitten into the lifting groove, the kelp sampling rod is lifted because the conical members of the pair of drum members are elastic regardless of the movement of the ship or the load. It hardly gets out of the groove. In this state, it is possible for the worker to simply receive the rising rod.

Eventually, as the weight balance of the whole kelp collecting rod becomes larger on the inside of the ship than on the sea side, the kelp collecting rod gradually falls down toward the worker, and it is almost horizontal with the ship. By then, kelp wrapped around Makka will appear on the sea.

Since kelp is a long seaweed, it has a large volume as a whole because it is entangled not only in the maca part but also in the root of the rod.

In this state, when the kelp collecting rod is sandwiched between the lifting grooves and lifted up, the diameter of the tip portion of the kelp collecting rod is larger than the groove width of the raising groove. The stick for kelp collection slips out and slips.

Here, if the operator stops the hydraulic motor and stops the rotating drum, the kelp can be taken into the ship. During this series of kelp sampling work, even if the kelp sampling boat constantly shakes or changes direction due to tides, wind, etc., the rotating drum is attached to the mounting base provided on the kelp sampling boat, It becomes possible to freely follow the change of the lifting angle of the kelp sampling rod.

The operator twists the kelp rod to the right as viewed from the operator side to collect kelp. Therefore, the worker must rotate the kelp collecting rod to the right so that the kelp does not fall off during the lifting of the kelp collecting rod, or take care that the kelp does not come off.

In the tidal current, the kelp sampling boat has its bow directed to the upstream side of the tidal current, and when the kelp is withdrawn in the tidal current, the kelp is entangled in the kelp collecting rod. The resistance becomes greater, and the tip of the kelp fishing rod and the kelp will be washed away in the stern direction, and the worker will lift the kelp fishing rod from the stern.

For this reason, the kelp sampling rod inclines slightly toward the stern side from a right angle to the lifting groove of the rotary drum. That is, the kelp sampling rod comes into contact with the surface of the conical member on the stern side of the two opposing surfaces of the lifting groove.

As a result, upward kinetic energy is given to the kelp rod being lifted by the conical member on the stern side on the sea side, and downward energy is applied by the conical member on the bow side on the worker side. The kelp sampling rod is pushed upward by the surface of the conical member on the stern side on the sea side from the center of the rotating drum, and pulled downward by the surface of the conical member on the bow side of the ship. It will make a rotational movement. In addition, if the angle between the rod and the rotary drum is increased, the rotation speed of the kelp sampling rod is increased, and if the angle is reduced, the rotation speed is reduced.

When the kelp is pulled up with the rope for collecting kelp, the width of the lifting groove of the lifting device is reduced by rotating the drum member on the other side. When the rope for collecting kelp is caught in the lifting groove, the rope is quickly drawn into the groove by the rotating motion of the rotating drum, and is wound forward along the bottom surface of the lifting groove.

However, since the rotating drum is provided with a drain groove plate having a plate surface so as to be in contact with the lifting groove, the kelp collecting rope drawn into the lifting groove is forcibly removed from the lifting groove by the drain groove plate. Will be discharged. All you have to do is manually bring the kelp into the ship.

[0029]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to FIGS. In the figure, what is indicated by reference numeral 1 is a kelp collecting rod and a rope lifting device. This kelp collection rod and rope lifting device (hereinafter referred to as the lifting device) 1
Has the following structure in order to make it possible to raise a kelp-collecting rod 2 (see FIG. 6) and a kelp-collecting rope 3 (see FIG. 9) described later.

That is, the two discs 4a, 4b have elastic (eg, rubber) conical members 5a, 5b having a trapezoidal cross section.
(See FIGS. 3 and 4) are attached to each of the drum members 7 by bolts 6, and two of these drum members 7 are arranged with the conical members 5 a and 5 b facing each other to form a pair of guide drum members 8. Is formed. A lifting groove 9 is formed between the conical members 5a and 5b of the pair of guide drum members 8.

A rotating cylindrical horizontal shaft member 10 for transmitting rotation to the pair of guide drum members 8 is provided inside the pair of guide drum members 8 along the axis. A side plate 10a is provided on one side of the rotating cylindrical horizontal shaft member 10,
The side plate 10a and the disk 4a are fixed by bolts 11.

Further, a side plate 10b provided on the other side of the rotating cylindrical horizontal shaft member 10 has a shaft center having a smaller diameter than the rotating cylindrical horizontal shaft member 10.
A threaded cylindrical member 13 provided with a screw portion 12 on the outer peripheral portion is fixed by welding. As a result, a rotary drum 14 for lifting the kelp-collecting rod 2 and the kelp-collecting rope 3 is formed.

When the drum members 7, 7 having the conical members 5a, 5b mounted on the disks 4a, 4b are mounted on the rotating horizontal shaft member 10, the parts of the conical members 5a, 5b will be replaced later. At times, it is very troublesome to remove it from the lifting device 1. Therefore, if the conical members 5a and 5b can be disassembled into a plurality of parts, the parts can be replaced without disassembling the entire lifting device 1.

The conical members 5a and 5b are elastic members such as rubber, and if they are used for a long period of time, the parts corresponding to the lifting grooves 9 and the like will be worn out and the parts will be replaced soon. become. At this time, for easy replacement, the one according to the present embodiment has conical members 5a, 5b as shown in FIGS.
Is divided into a plurality of parts. This also has the effect of reducing the cost of the mold for forming the conical members 5a, 5b.

The threaded cylindrical member 13 is welded to the rotating cylindrical horizontal shaft member 10 by screwing and inserting the center of the disk 4b on the other side. Thus, if the disk 4b is rotated together with the reinforcing plate 15 fixed integrally to the disk 4b, the width of the U-shaped lifting groove 9 with which the kelp collecting rod 2 and the kelp collecting rope 3 are engaged can be freely set. It is possible to flexibly cope with the width of the kelp collecting rod or the kelp collecting rope 3.
Further, a lock nut 16 is provided adjacent to the reinforcing plate 15 in order to fix the width of the lifting groove 9 at a constant value and prevent loosening.

The threaded cylindrical member 13 fixed to the rotating cylindrical horizontal shaft member 10 is connected to a hydraulic motor 19 fixed to an L-shaped mounting base 17 by bolts 18. That is, the rotation output shaft 20 of the hydraulic motor 19 is connected to the threaded cylindrical member 13.
And is fixed by a key 21, and is firmly fixed by screwing a bolt 22 from the center of the disk 4a and the side plate 10a toward the center of the rotary output shaft 20.

As a result, the power of the hydraulic motor 19 is reliably transmitted to the rotary drum 14. The hydraulic motor 19 is connected to a hydraulic pump (not shown) through a hydraulic valve 23. In the figure, reference numeral 23a denotes an operation lever.

The pair of guide drum members 8 in which the above-described lifting grooves 9 are formed have slopes 24a, 24b extending from the outer peripheral edge toward the middle.
The slopes 24a and 24b form a guide surface for the V-shaped kelp sampling rod 2 and the like. Therefore, the V-shaped slopes 24a and 24b can easily guide the kelp collecting rod 2 and the like to the lifting groove 9.

From the portion located inside the inclined surfaces 24a, 24b to the rotating cylindrical horizontal shaft member 10, the vertical surfaces 25a, 25
By b, two parallel surfaces are formed, and since these two surfaces are the lifting circumferential surfaces of the kelp sampling rod 2, a plurality of through holes 26 are provided to increase the frictional force. I have.

The lifting groove 9 with which the kelp sampling rod 2 engages will be described in further detail. The lifting groove 9 causes the conical members 5a and 5b to face each other, and forms two parallel and vertical surfaces by the vertical surfaces (circumferential planes) 25a and 25b of the conical members 5a and 5b. It has a U-shape composed of a total of three straight surfaces with one surface as a bottom surface.

The outer diameter of the rod 2 for collecting kelp usually ranges from φ30 to φ30.
Since it is 38th, the depth of the hoisting groove 9 is about 30 to 40 mm.

In order to secure the degree of elasticity of the elastic vertical surfaces 25a and 25b, the two vertical surfaces 25a and 25b are provided with a gap 27 between the rotating cylindrical horizontal shaft member 10 and the non-contacting vertical shaft member 10. The kelp collection rod 2 is placed in the U-shaped lifting groove 9
, Which makes it easier for the oppression of the vertical surfaces 25a and 25b to be transmitted to the kelp sampling rod 2.

Further, the vertical surface is increased so as to increase the frictional force.
As described above, the through holes 26 are provided on the entire surfaces of the surfaces 25a and 25b, and the depth of the withdrawal groove 9 is sufficiently deeper than the kelp sampling rod 2. Once fitted in the lifting groove 9, it cannot be easily pulled out.

When the rotating drum 14 is rotated to lift the kelp collecting rod 2, the kelp collecting rod 2 exerts a force to bite into the raising groove 9. Is strong.

In this state, the operator can lift the kelp only by receiving and supporting the kelp collecting rod 2 while the kelp collecting rod 2 is being lifted.

During the lifting of the kelp collecting rod 2, the distance from the center of the rotating cylindrical horizontal shaft member 10 to the kelp collecting rod 2 is determined by the position of contact with the vertical surfaces 25a, 25b and the rotating cylindrical horizontal shaft member 10. The vertical surface 25a, 25b is longer by the radius of the kelp sampling rod 2 at the position where it comes into contact with
Since the distance traveled by the rotation is long, the kelp sampling rod 2 being pulled is overloaded.

For this reason, by inserting another cylinder 28 so as to cover the portion of the rotating cylindrical horizontal shaft member 10 and keeping it free with respect to the rotating cylindrical horizontal shaft member 10, the kelp sampling rod during the withdrawal is removed. By preventing the kelp-collecting rod 2 from exerting an excessive force by preventing the kelp-collecting rod 2 from directly contacting the rotating cylindrical horizontal shaft member 10, the lifting operation of the kelp-collecting rod 2 proceeds more smoothly. .

When the rope 3 for collecting kelp is lifted by the lifting device 1, a winding prevention plate called a finger, that is, a drain plate 29 is lifted so that the rope 3 for collecting kelp does not get caught in the rotating drum 14. It is provided facing the groove 9. The thickness of the drain plate 29 is the rope 3 for collecting kelp.
Is slightly smaller than the width of the lifting groove 9 and is substantially rectangular.

The drain plate 29 is set up vertically on the bottom surface which is the horizontal plane of the L-shaped mounting table 17, the lower end thereof is fixed with a bolt 30, and the upper end is parallel to the bottom surface of the mounting table 17. It extends to a position almost in contact with the cylinder 28 on the center line in the width direction of the cylinder 10 and the cylinder 28.

Further, there is provided a plate surface 29a obtained by cutting one side of the discharge groove plate 29 starting from a position almost in contact with the cylinder 28 downwardly at an angle of about 45 degrees toward the outside of the groove 9. .

When the plate surface 29a is provided in this manner, the kombu collecting rope 3 fitted on the rotary drum 14 hits the obliquely cut plate surface 29a, and is not caught in the rotary drum 14 along the slope. Is discharged to the outside from the lifting groove 9.

In FIG. 1, reference numeral 31 denotes a round bar provided below the horizontal bottom surface of the L-shaped mounting base 17. This round bar
31 is inserted into a cylindrical mount 34 provided on the port 33 of the kelp sampling boat 32 (see FIGS. 6 and 9) so that the entire lifting apparatus 1 can move 360 degrees left and right over the mount 34 on the port 33. You can turn around.

As shown in FIG. 9, a chain 35 is connected to the seaside end of the seaweed collecting rope 3, and the chain 35 is connected to a macchi 36 which is a key metal fitting for seaweed collecting.

When the kelp collecting rope 3 is lifted, if the chain 35 is wound around the rotating drum 14, the rotating drum 14 is not only damaged but also dangerous. Therefore, the lifting groove 9 is provided on the kelp collecting rope 3 before the chain 35. A hose 37 (for example, a rubber hose) having a greater elasticity than the above is covered by about 1 m.

Next, the operation of this embodiment will be described. First,
The case where the kelp is pulled up using the lifting device 1 and the kelp collecting rod 2 of the present invention will be described. The lifting device 1
Is always installed on the port side of the kelp sampling boat 32.

The fisherman collects the kelp landing on the rock by the torsional fishing method ahead. At this time, there are a case where the fishing rod 2 for kelp is directly twisted and a case where a T-shaped handle is connected to the end on the hand side of the fishing rod 2 for kelp and it is turned and twisted. The kelp that has been entangled with maca and twisted is taken in by pulling up the kelp collecting rod 2.

Therefore, first, as shown in FIGS. 5 to 7, the kelp sampling rod 2 is pushed into the lifting groove 9 of the lifting device 1 and the rotary drum 14 is turned forward as viewed from the operator side (see FIG. 5 to FIG. 7). 6, arrow D), and the kelp collecting rod 2 can be pulled up. 6 and 7, reference symbol E indicates a ship side, and reference symbol F indicates a sea side.

In this case, the operator first slides the kelp sampling rod 2 along the slopes 24a and 24b, which are the guide surfaces of the rotary drum 14, and pushes the kelp sampling rod 2 lightly into the lifting groove 9. Since the rotating direction of the rotating drum 14 is rotating from the sea side to the ship side, the kelp sampling rod 2 is bitten into the lifting groove 9.

Since the lifting groove 9 is made of an elastic material such as rubber and has a U-shape having two parallel surfaces, the kelp-collecting rod 2 is pulled up toward the user at the same time as the lifting groove 9 without slipping. You will be drawn to the bottom and will bite more and more. This is a U-shaped lifting groove 9 unlike a V-shaped groove.
It is a big feature of.

In the state where the kelp sampling rod 2 is sufficiently bitten into the U-shaped lifting groove 9, the entire pair of guide drum members 8 is an elastic body regardless of the movement of the ship or the amount of load is small. Hardly fall out of the lifting groove 9.

In this state, the worker only has to lightly receive the kelp collecting rod 2 that is being lifted. Eventually, as the weight balance of the whole kelp collecting rod 2 becomes larger on the inside of the ship than the underwater side, the kelp collecting rod 2 gradually falls down toward the worker, and it becomes almost horizontal with the ship. By the time, kelp wrapped around Makka 2a appears on the sea.

Since the kelp is a long seaweed, the kelp is entangled not only with the maca 2a but also on the root of the kelp collecting rod 2, so that the volume is increased as a whole.

In this state, when the kelp extracting rod 2 is sandwiched between the U-shaped lifting grooves 9 and lifts up, the tip side of the kelp extracting rod 2 is larger than the groove width of the lifting groove 9. The kelp collecting rod 2 slips out and slips.

Then, the operator can operate the operating lever 23a of the hydraulic valve 23 to stop the rotation of the rotary drum 14, and take the kelp into the kelp sampling boat 32. During these series of sampling operations, the kelp sampling boat 35 constantly shakes or changes direction due to tide, wind, or the like.

However, the round bar 31 fixed to the lower part of the horizontal bottom surface of the L-shaped mounting base 17 is attached to the mounting base
Since it is inserted into the cylindrical part of 34, the entire lifting device 1
It is possible to freely rotate 360 °, and can freely follow the sway of the kelp sampling boat 32 and the change in the lifting angle of the kelp sampling rod 2.

Further, the kelp collecting rod 2 is to twist the right as viewed from the operator side to collect kelp (see arrow I in FIG. 7 ) .
See ). Even if it is twisted and entangled on a kelp rod, it cannot be harvested if it comes off the rod during the withdrawal.

Therefore, it is necessary for the worker to rotate the kelp collecting rod clockwise during the unloading, or to take sufficient care to prevent the kelp from falling off. In consideration of this point, the present apparatus is provided with a system in which the kelp sampling rod 2 is lifted while rotating clockwise during lifting.

During operation, the direction of the bow of the kelp sampling boat 32 is determined by the influence of the tide and the wind. The operation is not strong in strong winds, so the effect of the tidal current is particularly large. With respect to the tidal current, the kelp sampling boat 32 has its bow facing the flow so as to oppose the tidal current. That is, the bow is directed upstream of the flow.

In this state, when the kelp collecting rod 2 is collected by the kelp collecting rod 2, the tip of the kelp collecting rod 2 on the underwater side (the side of the maca 2a) faces the stern direction due to the resistance of the tide flow. Will be washed away.

Since the kelp is entangled with the kelp collecting rod 2 while the kelp is being twisted and withdrawn, the resistance of the tide is increased and the kelp is washed away. The rod 2 is pulled up from the stern direction.

Due to the above-described mounting base 34 for following the 360 ° turn, the kelp sampling rod 2 is not always lifted at a right angle with respect to the rotating drum 14, but the angle is slightly smaller on the sea side but on the stern. (Figure 7 angle α
reference).

The rotary drum 14 of the present apparatus has conical members 5a, 5b
Is a rubber-like elastic body, and when the conical members 5a and 5b face each other, a U-shaped lifting groove 9 having two parallel surfaces is formed. There is a slight gap between the bottom of
Since there are 27, the shape of the lifting groove 9 can flexibly cope with external deformation pressure.

This makes it easy to tilt the kelp collecting rod 2 slightly toward the stern side from a right angle with respect to the U-shaped rotary drum 14. That is, the kelp sampling rod 2 comes in contact with the stern side of the two opposing elastic members of the lifting groove 9 earlier in time.

Therefore, this slight time difference causes the upward kinetic energy of the conical member 5a on the stern side of the sea side F with respect to the kelp sampling rod 2 being withdrawn (see G in FIG. 7).
And a conical member on the bow side of the ship side E (operator side)
At 5b, downward energy (see H in FIG. 7) is applied.

As a result, the kelp collecting rod 2 is
7 is pushed upward on the left side of the sea side F (the surface of the conical member 5a on the stern side of the sea side F in FIG. 7) and the right side of the ship side E (the forward cone of the ship side E in FIG. 7). Since it is pulled downward by the surface of the member 5b), a function of generating a rightward rotational movement (refer to the symbol I) as a whole is added.
If the angle between the tangle 2 and the rotary drum 14 is increased, the rotation speed of the tangle 2 is increased, and if the angle is reduced, the rotation speed is reduced.

Conversely, the kelp sampling rod 2 is not brought into contact with the stern-side conical member 5a on the sea side F, and the kelp sampling rod 2 is brought into contact with the bow-shaped conical member 5b on the sea side F. If the angle is changed to the bow side of the sea side F, the rotation direction of the kelp sampling rod 2 will be rotated leftward, contrary to the above, but at the actual kelp operation site, the kelp sampling boat 32 and the tidal current Such things rarely occur.

In addition, during operation,
The conical member on the stern side of the sea side F with the intention of the kelp sampling rod 2
By moving the kelp collecting rod 2 so as to come into contact with 5a (in the ship side E, the kelp collecting rod 2 is moved to the bow side), the right rotation direction of the kelp collecting rod 2 during the withdrawal is further ensured.

Next, a case where the kelp is pulled up using the lifting device 1 and the rope 3 for collecting kelp will be described with reference to FIGS. 8 and 9. FIG. As described above, the lifting groove 9 of the rotating drum 14 is used.
Is a screw in which the conical member 5a on one side and the conical member 5b on the other side are fixed to the rotating cylindrical horizontal shaft member 10 and the disk 4a on one side, and are fixed to the rotating cylindrical horizontal shaft member 10 on the other side. With cylindrical member
The groove is a three-sided groove formed by the rotating cylindrical horizontal shaft member 10 in which the disk 4b is screwed and fixed to the screw portion 12 of the thirteen. And
The width of the lifting groove 9 is adjusted by adjusting the screw of the drum member 7 on the other side.

That is, since the rope 3 for collecting kelp is usually thinner than the rod 2 for collecting kelp, the disk 4b, the conical member 5b, and the reinforcing plate 15 screwed to the threaded cylindrical member 13 are rotated.
These are moved to one drum member 7 side, and the groove width of the U-shaped lifting groove 9 which opens in the radial direction is adjusted to the kelp sampling rope 3.
Adjust to fit and fix with lock nut 16.

The kelp collecting rope 3 cannot be received by hand during lifting, like the kelp collecting rod 2. Since the kelp collecting rope 3 is flexible, when it is bitten into the U-shaped lifting groove 9, it is immediately drawn into the bottom of the lifting groove 9 by the rotating motion of the rotary drum 14, and the bottom of the lifting groove 9 Along this side, the ship gets caught in the ship side E.

That is, the rotary cylindrical member 10 is lifted so as to be caught in the lifting groove 9 formed by the cylinder 28 provided on the outer peripheral surface of the horizontal shaft member 10 and the vertical surfaces 25a and 25b.

In order to prevent the rope 3 for collecting kelp from being entangled, a drain groove plate 29 having a plate surface 29a inclined outward is provided on the upper portion, so that the entangled rope hits this surface. In this case, since the action of the brake is performed, the rope 3 for collecting kelp is forcibly and smoothly discharged from the lifting groove 9 along the slope without being stopped.

Further, when the rope 3 for collecting kelp is pulled up more and more, the macchi 36 and the kelp, which are key fittings, can be seen. Operate the control lever 23a at this position to operate the rotating drum.
Even if 14 is stopped, it takes a considerable amount of time to pull out the rope 3 for collecting kelp that has been deeply bitten into the lifting groove 9 from the lifting groove 9 through about 180 °.

On the other hand, when the rope 3 for collecting kelp is pulled up, the chain 30 connected to the rope 3 for collecting kelp is wound around the rotating drum 14 and the rotating drum 14 is rotated.
Since it is not only a damage to 14 but also dangerous, a durable hose having a larger elastic force than the lifting groove 9, for example, a rubber hose 37 is covered by about 1 m on the kelp collecting rope 3 in front of the chain 30. At the rubber hose 37, the kelp collecting rope 3 rises up from the lifting groove 9 and turns around half a circle to reach the drain groove plate 29, all of which comes off the lifting groove 9 and slips on the slopes 24a and 24b. As a result, the rotary drum 14 stops exerting the lifting force, and in this state, the lifting operation of the kombu collecting rope 3 is stopped, and the operator can manually take in the kelp 38 hanging on the macchi 36 into the ship. it can.

Therefore, the lifting operation of the key called the macchi 36 is lightly pushed into the U-shaped lifting groove 9 along the inclination of the slopes 24a and 24b, which are the guide surfaces of the rotary drum 14, as in the case of the kelp sampling rod 2. As a result, the kelp-collecting rope 3 is deeply and deeply bitten by the groove, becomes close to the root while being discharged by the discharge groove plate 29, and stops rotation of the rotary drum 14 by a hose 37 sufficiently thicker than the width of the lifting groove 9. It is possible to automatically degroove without any trouble.

After that, it is only necessary to take the kelp 38 into the kelp sampling boat 32 manually. That is, the embodiment of the present invention has a function as a lifting device for not only the kelp collecting rod 2 but also the kelp collecting rope 3. The problem with the tide and the shaking of the kelp sampling boat 32 when using the kelp sampling rope 3 is the same as that relating to the withdrawal of the kelp sampling rod 2, and the description thereof will be omitted.

[Effects of the Invention] As described above, in the present invention, the lifting groove provided on the rotary drum is formed by an elastic conical member. When pressed against the kelp, the rod for collecting kelp is securely pulled into the lifting groove and bitten strongly. Thus, the kelp collecting rod can be easily pulled up.

Since the kelp sampling rod is held by the resilient conical member as described above, a steering wheel or an ammunition for holding the kelp sampling rod is not required, and the structure can be simplified. .

When the kelp sampling rod is to be lifted, the kelp sampling rod is attached to the port of the kelp sampling boat. Therefore, the kelp sampling rod is attached to the conical member on the stern side of the rotating drum rotating forward. If contact is made, the kelp sampling rod will automatically be turned clockwise. This eliminates the need for the operator to rotate the kelp sampling rod to the right, thereby improving work efficiency.

In particular, in the case of pulling up a kelp collecting rod in which kelp is entangled in a tidal current, the tip of the kelp collecting rod is subjected to the resistance of the tidal current due to the resistance of the tidal flow, since the bow is opposed to the tidal current. Natural contact with the conical member on the stern side of the rotating drum that is swept to the side and rotates, the kelp collecting rod is given a right rotation, and the kelp collected by twisting right is collected. It can be securely held without being detached from.

When the kelp to be landed on the rock is twisted by the kelp collecting rod, the kelp collecting rod is pushed into the lifting groove of the rotating drum, and the kelp collecting rod is pulled into the raising groove. Since the kelp can be lifted to the ship without slipping, the kelp can be easily lifted, and the kelp can be easily taken into the ship, thereby avoiding heavy labor when harvesting the kelp.

Even if the repetition of twisting and lifting the kelp rod is performed in this manner, the kelp can be easily filled with the kelp in the ship because the lifting operation is easy. Therefore,
The number of round trips to the docks and fishing grounds for kelp is increased, and the kelp harvest is increased. This makes it possible to easily overcome conventional heavy labor. In addition, kelp harvesting can be reformed in order to save labor and reduce labor and counter aging fishermen.
