Description

Description: TECHNICAL FIELD The present invention relates to a method for cutting algae that cuts seaweeds that have grown off the beach such as a beach, and that collects the cut seaweed surely so as not to dissipate. It is a thing.

[Prior Art] It has been a problem that seaweeds propagate in beaches and artificial beaches, which interferes with the bathing process.

Therefore, conventionally, in order to mow the propagated seaweed, the seaweed was cut with a toothed rotor type mower and loaded on the ship using a rake or a fork. There is a problem in that the species dissipate and adhere to the human body while bathing, which causes discomfort or the appearance around the beach is deteriorated.

On the other hand, in order to cut algae in the stagnant water of Lake Kawanumaike from the bottom of the water, hook the algae that are developing in the water on the conveying claws while moving, and cut them from the ground with a cutting blade that swings in the lateral direction.
The invention of Japanese Patent Laid-Open No. 55-21738 has been made relating to an algae mowing method and an apparatus for transporting the algae on a float, but in this case, there is a problem that the algae mowed cannot be reliably recovered.

[Problems to be Solved by the Invention]

The present invention has been made to solve the above-mentioned conventional problems, and it is an object of the present invention to provide a method for cutting algae that can be reliably and easily recovered at the same time as cutting algae. Is.

[Means for Solving the Problems]

As a means for solving the above-mentioned problems, the method for cutting algae of the present invention comprises a buoyant body on the upper part, and a cutter such as a wire or a chain on the lower end, and a strip-shaped net with a detachable mesh bag attached. So, after cutting the outer edge of the algae cutting work area, while winding both ends of the strip net, at the same time as cutting the alga with the cutter, at the same time collecting the cut alga with the strip net and in the mesh bag The mesh bag is housed and the mesh bag is pulled up.

As a result, after the algae in the cutting work area are cut with a wire or a chain, they are reliably collected with a band net, stored in a mesh bag, and transported to the disposal site together with the mesh bag removed from the band net. It will be.

〔Example〕

A procedure for carrying out a seaweed mowing work and an embodiment of an apparatus applied to the work will be described below with reference to the drawings, and FIG. 1 shows the seaweed mowing work. 2 is a plan view showing a state of time, FIG.
FIG. 3 is a plan view showing a developed state of the belt-like net shown in FIG.
A front view from the inside of an enlarged main part in the AA direction of the drawing, FIG. 4 is a side sectional view in the BB direction of FIG. 3, and FIG. 5 is a work of winding both ends of the belt-like net of FIG. A plan view of the ship and FIG. 6 are side sectional views of FIG.

First, in this embodiment, the starting point S is set along the outer edge of the work area X of FIG.
As shown in FIGS. 3 and 4, a buoyant body 1 is attached to the upper part, and a wire 2 or a chain for cutting seaweed is attached to the lower end, and an opening 5 is provided at approximately the middle part in the extension direction. In addition, the belt-shaped net 4 having the detachable mesh bag 3 is unloaded from the work boat 6 while navigating as indicated by an arrow F through the appropriate joint 12, and the belt-shaped net 4 moves so as to cover the sea area of the work area X. .

Next, when the work boat 6 has returned to the starting point S after the work area X has been covered, the hull of the work boat 6 is fixed there by the anchors 8 in FIG. Take up with a net take-up device such as winch 7 of.

As a result, the seaweed is cut by the wire 2 or the chain provided at the lower end of the belt-like net 4, and the cut seaweed is underwater in the sea area in the working area X surrounded by the belt-like net 4. It floats on the water surface and is stored in the mesh bag 3.

Next, as shown in FIG. 5, by operating the two winding devices such as the winch 7 and the like, the mesh bag 3 is lifted up on the slope 9 of the work boat 6, and the mesh bag 3 filled with the cut seaweeds is removed. Removing on the work deck 10 and attaching a new mesh bag 3 involves replacing the mesh bag 3, moving to the next work area, and repeating the same work procedure as above.

That is, since the buoyant body 1 is attached to the upper part of the strip net 4 and the wire 2 or the chain is attached to the lower end thereof, the strip net 4 is always perpendicular to the sea bottom, and therefore the wire 2 etc. Can scrape and release seaweeds by rubbing the seabed, collect these seaweeds with the band net 4, and store them in the mesh bag 3.
The mesh bag 3 removed from the strip net 4 can be efficiently transported to the disposal facility.

In this embodiment, the strip-shaped net 4 is unfolded, wound up,
An amphibious work boat 6 equipped with a shallow caterpillar (registered trademark) 11 is used so that the harvested seaweed can be continuously transported over the sea.

〔The invention's effect〕

According to the algae mowing method of the present invention described above, since the algae are cut off with a cutter such as a wire or a chain and are collected in a mesh bag at the same time as being collected by a band-shaped net, the algae are not scattered around. The band-shaped net reliably collects the mesh bag from its opening, so you can easily continue the work by replacing the mesh bag, improve the work efficiency, and easily dispose of the collected algae. Has the advantage that
