BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a collecting rod lifting device for seaweed.

[0002]

2. Description of the Related Art A conventional device of this type is, for example,
No. 27297 or Japanese Utility Model Laid-Open No. 5-43818. First, the former is one in which a kelp collecting rod is sandwiched between a driving roller and a guide roller arranged above it, and a receiving roller, and the driving roller is rotated to pull up the kelp collecting rod. In the latter, a pair of generally frusto-conical drums are attached to a rotating horizontal shaft with conical portions facing each other, a kelp sampling rod is fitted in the V-shaped groove formed there, and the drum is pulled up by rotation. It was done like this.

As described above, a heavy kelp collecting rod or a kelp collecting rod obtained by picking up a natural kelp that has grown on a reef on the sea floor is picked up from the root not by the labor force of a worker but by the rotating force of a machine. As it can be done, the kelp harvesting work becomes very easy.

[0004]

However, in each of the above-mentioned conventional examples, since the sampling rod is pulled up as it is,
There was a problem that the kelp that was picked up and entangled in the rod with great care slipped off from the rod due to the resistance of seawater.

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide a seaweed collecting rod pulling device for preventing seaweed entangled in a rod from sliding off.

[0006]

In order to achieve this object, a seaweed collection rod pulling device of the present invention is provided with a rotation drive means arranged at the rim of a seaweed collection ship and a rotation shaft of the rotation drive means. Equipped with a pair of two wheels that are arranged and have a gap that narrows from the outer circumference to the inner circumference, the seaweed collection rod is pressed against the pair of wheels, and the seaweed collection rod is pulled up as the wheels rotate. In the device, when the seaweed collecting rod is pressed against the pair of wheels, the seaweed collecting rod is tilted with respect to the plane perpendicular to the rotation axis so that the radial distance of the contact point of each wheel with the seaweed collecting rod is different. The guide means is provided.

[0007]

According to the above construction, since the radial distances of the contact points between each wheel and the seaweed collecting rod are different from each other, the rotational peripheral speeds at the contact points are different, so that the seaweed collecting rod is driven with the driving force in the pulling direction. , Rotational force is applied, and the seaweed collecting rod is pulled up while rotating so as to wind the seaweed. Therefore, it is possible to prevent the seaweed from sliding off the collecting rod due to the resistance of the seawater.

Embodiments will be described in detail below with reference to the drawings. 1 and 2 show an embodiment of the present invention, and a case of kelp, which is a kind of seaweed, will be described. 1
Is a pedestal of a kelp sampling rod lifting device fixed to a ship berth (not shown), 2 is a hydraulic motor attached to the pedestal 1, 3 is a worm attached to the motor shaft of the hydraulic motor 2, and 4 is a mesh with the worm 3. Worm wheels 5 are rotary shafts to which the worm wheel 4 is attached and which rotate via the worm gear device according to the rotation of the hydraulic motor 2.

Reference numerals 6 and 7 denote a pair of two wheels A and B fixed to the rotary shaft 5, and both wheels A,
The gap B is wide at the outer peripheral portion in the radial direction and narrow at the inner peripheral portion. Further, for example, rubber having a large frictional resistance is attached to the surfaces of the wheels that face each other. 8 and 9
Are guide members A and B arranged so as to surround the outer peripheries of the wheel A6 and the wheel B7, respectively. The guide members A8 and B9 are inserted into the sea and a picking portion (not shown) provided at the tip thereof. It is for guiding the hand part of the kelp collecting rod 10 obtained by picking up the natural kelp that has grown on the reef on the seabed from the root between the wheels A6 and B7.

Further, the guide members A8 and B9 are
Each has a unique shape, and if the kelp harvesting rod 10 is guided along the shape between the wheels and pressed against the wheels A6 and B7, the kelp harvesting rod 10 will face the plane perpendicular to the rotation axis 5. It enters in an inclined state, and as a result, it comes into contact with the wheel A6 at the point p ₁ and the wheel B7 at the point p ₂ .

Next, the operation of this embodiment will be described. First,
Insert the kelp harvesting stick 10 into the sea, pinch the root of the natural kelp with the picking part provided at the tip, and twist the kelp collecting stick 10, and the kelp will be picked from the root and entangle with the kelp collecting stick 10. Next, operate the hydraulic motor 2 of the kelp sampling rod lifting device,
Rotate the pair of wheels A6 and B7 to remove kelp
The proximal portion of 10 is guided between the wheels A6 and B7 according to the guides of the guide members A8 and B9. Kelp pickup rod 10 is in contact with p ₁ point and p ₂ points of the wheels A6 and B7, raised in the direction of arrow F by the rotation of the wheel A6 and B7.
At the same time, a radial distance r ₁ from the rotary shaft 5 to the p ₁ point, p ₂
Since the radial distance r ₂ to the point is different, the rotating peripheral speed at each contact point is different, and as a result, the kelp sampling rod 10 rotates in the direction in which the kelp is wrapped. That is, the picked kelp is pulled up while being wrapped around the kelp picking rod 10, so that the picked kelp does not fall off even if there is resistance to seawater on the way, and it is possible to reliably pick it up.

In addition, although natural kelp has been described in the examples, the present invention can be generally applied to the collection of seaweed that has grown on a reef on the sea floor. Further, the shape of the guide member is not limited to the one shown in the embodiment, in short, the seaweed collecting rod is inclined with respect to a plane perpendicular to the rotation axis,
Any guide may be used as long as the radius of the contact point between each wheel and the seaweed collecting rod is different.

[0013]

As described above, according to the present invention, when the seaweed sampling rod is pressed against the pair of wheels A and B, the radial distance r ₁ where the wheel A contacts the seaweed sampling rod and the radius where the wheel B contacts. The feature is that the guide means for guiding between the wheels is provided so as to make the distance r ₂ different, thereby eliminating the problem that the picked seaweed is dropped during the harvest, and the seaweed collecting rod can be safely used. The effect of being able to pull up and reliably collect is exhibited.
