いた。[Prior Art] Conventionally, in order to harvest seaweed such as wakame that has been grown using a parent rope, as shown in Fig. 4,
The main rope 4, which has been stretched to an underwater aquaculture facility, is manually pulled up from the fishing boat using the hook 24, and while the main rope is floating near the sea surface, the user leans out over the gunwale and uses one hand to pull the main rope.
They grabbed the roots of "Wakame" etc., and used the handle sickle or ring-shaped blade 25 with the other hand to cut the stems of "Wakame" etc. and pulled them onto the ship. The main ropes from which wakame and other seeds were cut would sink into the sea due to the weight of the roots, so they were hauled onto the boat by hand. In addition, the stumps attached to the parent rope could not be removed on board the ship, so they were removed on land using hammers or knives.

損傷する欠点がある。[Problems to be Solved by the Invention] The conventional method of harvesting seaweed such as "wakame" as described above is to harvest "wakame" etc. that have been grown on a parent rope stretched in the sea by leaning out from a fishing boat. Because harvesting is carried out manually in seawater, there is a risk of the ship tipping over, and the work can only be done when the sea surface is calm, requiring a great deal of labor and not improving efficiency.Furthermore, the roots must be processed on board the ship. Because it is difficult to remove the main rope, the main rope must be brought back to land and the stumps must be removed using hammers, knives, etc., and this work also requires a lot of manpower and has the disadvantage of damaging the main rope.

It is an object of the present invention to provide a novel method for harvesting seaweed that can mechanically crush the parent rope without damaging it, and a device for harvesting the same.

The flanges of the drum having a horizontal axis are axially outwardly open to each other, and each flange has small holes drilled at the same pitch on the same radial circumference approximately in the radial center of each flange. The guide drum has a small hole connected by a rope, and the center of the arm is fixed horizontally to the top of a vertical column fixed on the ship.

Since it falls between the ropes, it is not held down by the parent rope and the seaweed is not damaged. In addition, since seaweed is harvested from the main rope on board, the stalks are easier to see than harvesting at sea, which requires less labor and is more efficient. After the seaweed has been harvested, some root stocks remain attached to the parent rope, but the parent rope that has been hoisted up by the hoisting device is passed through the two root guide pipes of the stock removal device, the fixed pipe, and the gap adjustment pipe. By passing between the fixed pipe and the gap adjustment pipe, the root stock is compressed and crushed by the pressing force generated from the binding force of the rubber member acting between the fixed pipe and the gap adjustment pipe, and falls onto the chute and is collected.

An arm 10 having an elongated rectangular upper surface is mounted on the upper end of the support column 8 provided perpendicularly to the frame of the drum 5 so that the arm 10 is parallel to the axis of the drum 5 and the center of the arm 10 is located equidistant from both flanges of the drum 5. established in One ends of two dogleg-shaped guide pipes 11 are fixed perpendicularly to the upper surface of the arm 10 along the side of the arm 10 on the guide drum 20 side at an appropriate distance from each other. Therefore, a straight line connecting the centers of the fixed ends of both fixed guide pipes 11 is parallel to the rotation axis of the drum 5. The upper ends of the guide pipes 11 face the guide drum 20, and the planes including the center lines of both guide pipes 11 are parallel to each other and intersect at right angles to the rotation axis of the drum 5. Good results can be obtained by setting the distance between both guide pipes 11 to 45 mm.

Directly above the fixed pipe 12, a gap adjustment pipe 13 having the same diameter as the fixed pipe and a slightly longer overall length is placed horizontally, and the fixed pipe 12 and the gap adjustment pipe 13 are connected to each other by stretchable rubber strings 14 at both ends thereof. They are tied up together. The strength with which the rubber string 14 binds both pipes 12 and 13 is adjusted in advance depending on the size and hardness of the root stock 3 attached to the main rope 4. The root stock 3 passing through the gap between the pipes 12 and 13 is crushed by the pressing force generated when pushing up the gap adjustment pipe 13. This pressing force is based on the direction in which the main rope 4 moves,
Due to the direction of the force of the root stock 3 trying to push up the gap adjustment pipe 13, the gap adjustment pipe 13 is pushed up against the guide pipe 11.
The elasticity of the rubber string 14 tied to the fixed pipe 12 provides the elasticity of the rubber string 14 that is tied to the fixed pipe 12 when moving upward along the horizontal axis. A diameter of 27 mm for the fixed pipe 12 and the gap adjustment pipe 13 gives good results.

いでいる。A guide drum 20 is provided on the bow side and is rotatable around a stand 19 and rotatable around a horizontal shaft 18 that can be adjusted up and down. The inner surfaces of the flanges 21 of the guide drum 20 are open toward each other in the axial direction. Therefore, it becomes easy to guide a large amount of "wakame" or other plants attached to the parent rope 4 to the guide drum 20. Ten small holes 22 of equal pitch are provided on concentric circles equidistant from the horizontal axis 18 at approximately the center of each flange in the radial direction, and a rope 23 is stretched across each opposing small hole. . When the "wakame" etc. 2 attached to the main rope 4 by the root stock 3 are guided to the guide drum 20 and hoisted onto the ship by the hoisting device, the main rope 4 is placed on the guide drum 20.
Since the part pressed down by the rope 23 falls toward the center of the guide drum 20 through the gap where the rope 23 is stretched, the "wakame" etc. 2 are prevented from being damaged by the main rope 4.

One end of the parent rope 4 of the "wakame" etc. 2 that has been trained in the sea is pulled up from the bow side, passes over the rope 23 of the guide drum 20, and is then passed through the guide pipe 11 of the root removal device 9 and the two fixed pipes 1.
2. It passes between the gap adjustment pipes 13, passes through the guide rollers 15, and is wound up by the drum 5 of the winding device 7 at an appropriate speed. At this time, the "wakame" etc. 2 attached to the parent rope 4 are cut off from the stems using a knife on board the ship and harvested onto the net 17. When the root stock 3 from which the "wakame" etc. 2 has been cut off passes between the pipes 11, 12 and 13 of the root removal device 9 while still attached to the parent rope 4, it acts between the gap adjustment pipe 13 and the fixed pipe 12. It is crushed by the pressing force and falls onto the chute 16. If a net 17 is laid on the ship and the "wakame" etc. 2 and the crushed stumps 3 are accumulated thereon, it becomes easy to lift the net to land using a crane or the like.
