DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seaweed picking and removing apparatus mounted on a seaweed picking boat for collecting seaweed algae from a seaweed net installed in the sea.

[0002]

2. Description of the Related Art The production process of a sheet-like laver product is as follows. (1) Ride on a nori picking boat and collect the nori original algae from the underwater laver net. (2) After washing the collected seaweed progenitor algae, it is chopped and minced. (3) The minced laver is applied to a laver machine to form a laver having a predetermined thickness as a laver mistake. (4) Dry the nori mistake with a dryer. (5) A predetermined number of dried nori are bundled to form a product.

[0003] If a foreign substance is mixed in a dried laver product, the quality of the laver product is remarkably impaired, resulting in a defective product or a lower grade of the product, which is disadvantageous in cost. Conventionally, foreign matter of nori before shipment is removed by TV camera or CC
A method of detecting with a D sensor and sorting it into non-defective products and defective products has been widely adopted by laver producers.

[0004]

However, in recent years, rising sea levels, which are thought to be caused by global warming, have caused shore debris to be washed away by waves and flowed into the sea, resulting in many foreign matter floating in laver fishing grounds. Phenomenon has been seen. Types of garbage include straw in paddy fields, reeds on riversides, and discarded vinyl waste.

[0005] If such suspended matter is mixed into the original seaweed itself, the rate of seaweed that is classified as defective during shipping inspection after the production of seaweed increases. Since the production capacity of automatic laver production machines is limited, the contamination of foreign substances results in a decrease in producer income.

[0006] Conventionally, foreign substances were found and removed by hand at the stage of the original seaweed of nori collected by a nori picking boat. However, in the case of human hands, oversight or inefficiency was observed, or the condition of the day was poor. There was a problem that the detection rate fluctuated.

Various methods for automatically performing this have been proposed (for example, see Japanese Patent Application Laid-Open No. 4-36169). However, there has been a problem that the cost is high and the burden on general producers is high. In addition, since the removal rate of foreign matter is limited in an automatic machine, there is a problem that the yield is reduced if foreign matter is largely mixed in the laver original algae itself when collected.

The problem to be solved by the present invention is
To remove foreign matter as much as possible at the stage of collecting laver from the laver net with a laver picking boat, to reduce the burden of foreign matter removal in the laver manufacturing process after collection, and thereby to improve the yield of laver for producers It is in.

[0009]

Means for Solving the Problems To solve the above-mentioned problems, the apparatus for eliminating the inclusion of suspended matter on the sea in a laver picking machine according to the present invention is mounted on a laver picking boat that moves while approaching a laver net installed in the sea. In the seaweed picking machine, the base end is attached to the seaweed picking boat side, the tip extends in the traveling direction of the seaweed picking boat during seaweed picking work, and a seaweed net guide that once dive the seaweed net below the water surface , and a suspended matter removal blades to eliminate the suspended solids is attached to the tip of the laver network guide outside the width of the seaweed network, this suspended matter removal
A net for recovering suspended matter removed by the blade is provided .

In the above apparatus, the base end of the laver net guide is swingably attached to a laver picking boat, and a substantially middle portion in the height direction of the suspended matter removing blade is drafted at the tip end of the laver net guide. Floats can be installed that function to be maintained at the level.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to examples. FIG. 1 is a side view showing an embodiment of the apparatus for eliminating the incorporation of suspended matter on the sea according to the present invention, and FIG.

In these figures, 1 is a laver picking boat called a so-called kakushu, 2 is a laver picking machine mounted on the laver picking boat 1, 3 is a support provided on the nori picking machine, and 4 is elimination of suspended matter floating on the sea. Device. The marine suspended matter contamination elimination device 4
It has a laver net guide 5 whose base end is swingably attached to the column 3, and a float 6 and a suspended matter removing blade 7 are mounted at the tip of the laver net guide 5. The float 6 can be used to swing the nori picking boat 1 or the nori picking boat 1
Even when the draft is lowered because the seaweed is almost full, the seaweed net guide 5 is floated so that the substantially middle part of the suspended matter removing blade 7 in the height direction is maintained at the draft level. The suspended matter removing blades 7 are attached linearly to the left and right from the head of the float 6 formed in an isosceles triangular shape, and the protruding length thereof can be adjusted. In this embodiment, the suspended matter removing blade 7 is formed of a flexible plastic plate.

In this embodiment, an example is shown in which the laver net guide 5 is attached to the support 3 of the laver picking machine 2. However, as long as it is a place where the laver picking work is not hindered, another place of the laver picking boat 1 is used. It may be attached to.

Next, the operation of the apparatus 4 for eliminating marine suspended solids will be described. The laver net 10 is stretched from a supporter called a laver crack that is erected at a predetermined interval to a net rope near the sea surface via a hook. In the laver net 10, floating bamboos 11 are provided at predetermined intervals so that portions other than the supported portions do not sink.

The seaweed picking boat 1 travels while approaching a seaweed net 10 stretched near the sea surface, picking seaweed from the seaweed net 10 on the ship, and returning the seaweed net 10 to the sea.

Conventionally, when the seaweed net 10 is lifted from the sea surface, the foreign matter floating on the sea surface is scooped up, so that the floating matter easily adheres to the seaweed net 10. In the present invention, before the laver net 10 is pulled up to the laver picking boat 1, the laver net 10 is once sunk into the sea by the laver net guide 5, so that foreign substances floating on the sea surface do not adhere to the laver net 10. At this time, foreign substances floating on the sea surface are simultaneously removed by the floating substance removing blades 7 into the laver net 10.
To the outside of the area. Since the laver picking boat 1 is moving on the sea surface while approaching the laver net 10, the laver net 1
Floating matter is eliminated in the area where 0 is raised, and therefore, when the laver net 10 is raised to the laver picking boat 1, the suspended matter is eliminated.

[0017] In this manner, the nori-produced algae collected include:
Since the suspended matter is eliminated, the suspended matter removing operation in the laver manufacturing process is significantly reduced, and the yield of the product is improved.

The above is the operation of the apparatus for eliminating the incorporation of marine suspended matter according to the present invention. The removed suspended matter will float on the sea surface again, and the degree of foreign matter contamination may increase for other laver producers. There is. Therefore, the tip of the suspended matter removal blade 7
An opening 7a is formed in the opening, and collected at the rear of the opening 7a.
The net 8 is detachably attached.

The provision of the recovery net 8 allows floating
The suspended matter distributed to the left and right by the removal blade 7 is opened.
The user enters the collection net 8 through the mouth 7a. A series of seaweed picking
When the operation is completed, dispose of the suspended matter in the collection net 8.
You.

[0020]

As described above, according to the present invention, suspended matter is removed as much as possible at the stage where laver is collected from the laver net by a laver picking boat, and the burden of removing foreign matter in the laver manufacturing process after collection is reduced. It is possible to reduce the amount of seaweed and thereby increase the yield of laver in the producer. In addition, any power,
Since it does not use fuel, it meets the demands for resource and energy savings that have been raised in recent years.

Further, by providing the collection net, it is possible to collect the removed suspended matter without disturbing other laver producers, and on the contrary, it can also serve as cleaning of floating dust. This has a tremendous effect, as it helps protect the global environment from pollution.
