[0002]

[Prior art and problems] For natural kelp harvesting work, hold a fishing rod with a hook at the tip, insert the fishing rod aiming at the kelp, twist the kelp with the hook to collect, and lift the fishing rod. The kelp was taken into the kelp collection boat. This natural kelp harvesting work was performed manually from the insertion of the harvesting rods to the lifting of the harvested kelp, so at least two workers are required to withdraw the heavy harvesting rods from which the kelp was harvested. And 1
At the same time a person pulled up the sampling rod, another person pulled up the hook and took kelp into the sampling vessel.

[0003] In such natural kelp harvesting work, since the lifting work of the collected heavy kelp is a heavy labor, even two people are very tired and the lifting work is inefficient.

The present invention is based on the above-mentioned circumstances, the increase in the number of elderly workers due to the recent shortage of young workers, and the natural kelp, which is grown in a rocky place, when kelp is grown in a deep place. In light of the fact that it is difficult to manually lift a heavy harvested kelp by hand, even an old worker can reduce the fatigue of a heavy harvested kelp and the efficiency of the harvested rod. An object of the present invention is to provide a natural kelp harvesting rod lifting device that can be lifted well.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the means of the present invention is, in claim 1, a pair of one-sided drum constituent members formed in a substantially truncated cone shape and the other side. A drum component is attached to a power rotation horizontal shaft with conical parts facing each other, and a rotation drum is formed in which a V-shaped lifting groove is provided all around the rotation horizontal shaft. One side of the rotation drum An ammunition for elastically pressing the drum component toward the drum component on the other side is wound around one end of the power rotating horizontal shaft, and a nut is screwed onto one end of the rotating horizontal shaft to form a rod lifter. It means that this rod-lifting machine is loosely fitted to the vertical axis that is arranged on the port of the kelp sampling ship. In claim 2, a pair of one-sided drum constituent members formed in a substantially truncated cone shape and other The side drum component is attached to the power rotation horizontal shaft with the conical portions facing each other, and the V-shaped lifting is performed on the entire rotation horizontal shaft. A rotary drum around which one side drum component member is elastically pressed toward the other drum component member is wound around one end of the power rotating horizontal shaft, A nut is screwed onto one end of the shaft, and an auxiliary wheel that can move up and down and can be erected up and down is arranged parallel to the rotary drum so as to face the rotary drum to form a fishing rod lifting machine. It means that it was loosely fitted to the vertical axis to be placed on the port.

[0006]

[Operation] According to claim 1, the power-revolving horizontal axis of the rod lifting machine is rotated in the pulling direction by power to rotate the rotating drum synchronously, and the heavy hand-held collecting rod is obtained by twisting the natural kelp and sampling. The natural kelp collected can be taken into a kelp sampling ship by fitting it into the pulling groove of the rotary drum and using the rotation of the rotary drum to manually pull up the sampling rod. Then, if the rotary drum idles with respect to the hand-held collecting rod during the lifting of the collected kelp, the collecting rod is directed toward the bottom side of the collecting groove by utilizing the V-shaped lifting groove. By pressing and fitting deeply, pressing the ammunition with the collecting rod through the one-side drum component of the rotating drum toward the nut, and strengthening the elastic force of the ammunition against the collecting rod during the above-mentioned collecting kelp lifting, The sampling rod is pressed against the groove surface of the pulling groove more strongly, eliminating idling of the rotating drum,
The collected natural kelp is taken into the kelp collecting ship by pulling the collecting rod by hand while utilizing the rotation of the rotary drum. In addition, the kelp-collecting ship that is collecting natural kelp constantly changes direction depending on the tidal current and wind direction, and turns, but since the rod lifting machine is loosely fitted to the vertical axis on the kelp-collecting ship side, Even if the fishing rod of No. is fitted in the pulling groove, the fishing rod is relatively rotated around the vertical axis by 360 ° in response to the direction change and turning of the kelp fishing boat, and it rotates. The rod lifter prevents breakage of the fishing rod due to turning or turning of the kelp fishing boat.

According to claim 2, in addition to the function of claim 1, a sampling rod fitted in the pulling groove of the rod lifting machine is provided with a rotary drum, and an auxiliary wheel capable of moving up and down and facing the rotary drum. If it is sandwiched with and, since the rotating drum is rotating in the lifting direction, it will not be submerged in the sea even if you remove your hand from the fishing rod during the lifting of the harvested kelp. In addition, since the auxiliary wheels can stand up and down, when the collected kelp is taken into the kelp sampling ship, if the arrangement mode of the auxiliary wheels is changed from standing up to lodging, the collection rods that are being lifted will move along It is prevented that the hand side gradually descends, the collected kelp side rises, and the kelp is scraped off by rubbing it against the port.

The auxiliary wheel 7 is configured such that a piston rod of a hydraulic cylinder 21 arranged on the upper surface of the tip of an auxiliary frame 18 is connected to a mounting frame 20 so as to be vertically movable, and a sampling rod r fitted in a lifting groove 3 is attached to a rotary drum 1. Configure so that you can slide between and.

The auxiliary wheel 7 constructed as described above can be rotated by rotating the auxiliary frame 18 toward the rotary drum 1.
When the auxiliary frame 18 is rotated in the circumferential direction of the rotating drum 1 and is arranged in parallel to face the rotating drum 1, the upper side of the rotating drum 1 is kept facing the rotating drum 1 and close to the rotating drum 1. When the hydraulic cylinder 21 is actuated, it moves up and down. The hydraulic cylinder 21 may be a single-acting type or a double-acting type.

The method of using the above described natural kelp harvesting rod lifting device will be described, but the description overlapping with the description of claim 1 will be omitted.
When it is necessary to remove the hand from the collecting rod r during the lifting of the natural collecting kelp, the collecting rod r is fitted into the lifting groove 3 of the rotating drum 1 rotating in the lifting direction of the collecting rod r, and the auxiliary wheel 7 is used. Is placed opposite to the lifting groove 3 to adjust the height position, and the sampling rod r is sandwiched by the rotary drum 1 and the auxiliary wheel 7. Released sampling rod r
Since the rotating drum 1 is rotating in the lifting direction, there is no fear that the rotating drum 1 will be submerged in the sea even if the collected kelp is heavy. In addition, even if the kelp-collecting ship S, which is collecting natural kelp, constantly changes its direction and turns, an auxiliary frame is added depending on the movement.
If 18 is rotated in the circumferential direction of the rotating drum 1 and the auxiliary wheel 7 is erected or laid down, the sampling rod r fitted in the pulling groove 3 is always grasped by the rotating drum 1 and the auxiliary wheel 7 and squeezed by hand. It is possible to withdraw. In addition, the hand side of the collecting rod r being lifted is lowered toward the bottom of the ship to collect the collected kelp and the kelp collecting ship S.
When the auxiliary wheel 7 is rotated in the circumferential direction of the rotating drum 1 to change the arrangement mode from standing to fall, the hand side of the sampling rod r gradually descends as the auxiliary wheel 7 rotates, and the sampling kelp is taken. It can be taken in without worrying that the kelp will rise and the kelp will rub against the port and fall off the hook.
