本発明に係る海苔養殖用肥料散布装置を示す説明図。BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an explanatory view showing a fertilizer spraying device for seaweed cultivation according to the present invention; 本発明に係る海苔養殖用肥料散布方法を示す説明図。BRIEF DESCRIPTION OF THE DRAWINGS Explanatory drawing which shows the fertilizer application method for seaweed culture which concerns on this invention.

以下に、本発明に係る海苔養殖用肥料散布装置及び海苔養殖用肥料散布方法の具体的な構成について図面を参照しながら説明する。 Hereinafter, specific configurations of the fertilizer application apparatus for laver cultivation and the fertilizer application method for laver cultivation according to the present invention will be described with reference to the drawings.

図１に示すように、海苔養殖用肥料散布装置１は、船体２の後端に推進及び操舵可能な船外機３を取付けている。船外機３には、コントローラ（図示省略）が接続されており、コントローラによって海苔養殖用肥料散布装置１（船体２）の推進方向や推進速度を制御することができるようにしている。 As shown in FIG. 1, the fertilizer application apparatus 1 for seaweed farming has an outboard motor 3 that can be propelled and steered at the rear end of a hull 2 . A controller (not shown) is connected to the outboard motor 3, and the controller can control the propulsion direction and the propulsion speed of the fertilizer spraying device 1 (hull 2) for laver farming.

船体２は、前側に液状の海苔養殖用肥料４を散布するためのノズル５を船体２の左右幅方向に向けて間隔をあけて複数設けている。 The hull 2 is provided with a plurality of nozzles 5 for spraying the liquid nori aquaculture fertilizer 4 on the front side at intervals in the lateral width direction of the hull 2 .

ノズル５は、海苔養殖用肥料４を上方へ向けて噴射できればよく、噴射する方向や速度を変更できるようにしてもよい。その場合には、ノズル５にコントローラを接続して、コントローラによって海苔養殖用肥料４の噴射方向や噴射速度を制御できるようにする。 The nozzle 5 only needs to be able to jet the manure 4 for cultivating seaweed upward, and the direction and speed of jetting may be changed. In that case, a controller is connected to the nozzle 5 so that the injection direction and injection speed of the laver culture fertilizer 4 can be controlled by the controller.

また、船体２は、後側に海苔養殖用肥料４を貯留するとともにノズル５から散布した余剰の海苔養殖用肥料４を回収するための上方を開口させたタンク６を設けている。 In addition, the hull 2 is provided with a tank 6 with an upper opening for storing the manure 4 for cultivating seaweed on the rear side and recovering the manure 4 for cultivating seaweed that has been sprayed from the nozzle 5 .

タンク６は、海苔養殖用肥料４の濃度を調節するための濃度調節機や異物を除去するための異物除去装置を設けてもよく、また、余剰の海苔養殖用肥料４の回収効率を向上させるために開口部に漏斗状の周壁を設けてもよい。 The tank 6 may be provided with a concentration adjuster for adjusting the concentration of the laver aquaculture fertilizer 4 and a foreign matter removal device for removing foreign matter, and also improve the recovery efficiency of the surplus nori aquaculture fertilizer 4. For this reason, the opening may be provided with a funnel-shaped peripheral wall.

タンク６は、ノズル５にポンプ７を介して接続している。ポンプ７は、コントローラに接続されており、コントローラによってノズル５から噴射される海苔養殖用肥料４の噴射量を制御できるようにしている。 Tank 6 is connected to nozzle 5 via pump 7 . The pump 7 is connected to a controller so that the controller can control the injection amount of the laver culture fertilizer 4 injected from the nozzle 5 .

海苔養殖用肥料散布装置１は、以上に説明したように構成されており、海苔の養殖時に、海苔養殖用肥料４を散布するために使用される。 The laver farming fertilizer spraying device 1 is configured as described above, and is used for spraying the laver farming fertilizer 4 during laver farming.

海苔の養殖は、海底８に複数本の支柱９を前後及び左右に間隔をあけて立設し、各支柱９に浮動環10を支柱９に沿って昇降自在に設け、各浮動環10に吊綱11を介して海苔養殖網12を取付けている。各浮動環10は、支柱９の上端部に取付けられた取付綱13が取付けられている。これにより、潮の干満に応じて支柱９に沿って浮動環10が昇降し、それに合わせて海苔養殖網12が海面14に張設され、また、干潮時には、浮動環10の下降が取付綱13によって規制され、海苔養殖網12が海面14よりも上方で吊設され、養殖されている海苔の天日による殺菌が行われる。 Nori seaweed is cultivated by erecting a plurality of pillars 9 on the seabed 8 with intervals in the front, back, left and right, and providing a floating ring 10 on each pillar 9 so that it can move up and down along the pillar 9, and hanging on each floating ring 10. A seaweed cultivation net 12 is attached via a rope 11 . Each floating ring 10 is fitted with a tether 13 attached to the upper end of the strut 9 . As a result, the floating ring 10 moves up and down along the pillars 9 according to the ebb and flow of the tide, and the seaweed cultivation net 12 is stretched on the sea surface 14 accordingly. The seaweed culture net 12 is suspended above the sea surface 14, and the cultured seaweed is sterilized by the sun.

この海苔養殖網12が海面14よりも上方で吊設している状態においては、海苔養殖網12が海面14から離間しており、海面14と海苔養殖網12との間で海苔養殖用肥料散布装置１を移動させることができる。 When the seaweed aquaculture net 12 is suspended above the sea surface 14, the seaweed aquaculture net 12 is separated from the sea surface 14, and fertilizer for laver aquaculture is spread between the sea surface 14 and the nori aquaculture net 12. The device 1 can be moved.

そこで、支柱９に昇降自在に吊設した海苔養殖網12が海面14から離間している時に、図２示すように、海苔養殖網12に沿って海苔養殖用肥料散布装置１を移動させながら、タンク６に貯留した海苔養殖用肥料４をノズル５から海苔養殖網12に向けて散布し、同時に海苔養殖網12や海苔に付着しなかった余剰の海苔養殖用肥料４をタンク６に回収する。なお、図２において、白抜き矢印は、ノズル５から海苔養殖用肥料４を散布せずに海苔養殖用肥料散布装置１が移動することを示し、黒塗り矢印は、ノズル５から海苔養殖用肥料４を散布しながら海苔養殖用肥料散布装置１が移動することを示している。 Therefore, when the seaweed cultivation net 12, which is vertically suspended from the pillars 9, is separated from the sea surface 14, as shown in FIG. The laver aquaculture fertilizer 4 stored in the tank 6 is sprayed from the nozzle 5 toward the laver aquaculture net 12, and at the same time, surplus nori aquaculture fertilizer 4 not adhering to the laver aquaculture net 12 or laver is collected in the tank 6.例文帳に追加In FIG. 2 , the white arrow indicates that the fertilizer for laver farming 1 is moved without spraying the manure for laver farming 4 from the nozzle 5 , and the black arrow indicates that the manure for laver farming is dispensed from the nozzle 5 . It shows that the fertilizer spraying device 1 for laver cultivation moves while spraying 4.

その際に、人手やコントローラによって船外機３やノズル５やポンプ７を調整することもでき、ノズル５から海苔養殖網12に向けて散布した余剰の海苔養殖用肥料４が全てタンク６に回収される速度となるように船体２の進行速度やノズル５の噴射速度などを調整することもできる。 At that time, the outboard motor 3, the nozzle 5, and the pump 7 can be adjusted manually or by a controller, and the surplus seaweed farming fertilizer 4 sprayed from the nozzle 5 toward the seaweed farming net 12 is all collected in the tank 6. It is also possible to adjust the traveling speed of the hull 2 and the jetting speed of the nozzle 5 so as to achieve the desired speed.

また、遠隔操作によって海苔養殖用肥料散布装置１を制御するようにしてもよく、ＧＰＳ信号等を用いて予め設定されたルートで海苔養殖用肥料散布装置１を移動させながら海苔養殖用肥料４の散布及び回収を行わせることもできる。また、海苔養殖用肥料散布装置１に上方の海苔養殖網12を検出するセンサーを設けて、センサーで上方に海苔養殖網12が存在することを検出した場合にノズル５から海苔養殖用肥料４を散布するようにしてもよい。 Further, the laver farming fertilizer spraying device 1 may be controlled by remote control, and the laver farming fertilizer spraying device 1 is moved along a preset route using a GPS signal or the like to apply the laver farming fertilizer 4. Spraying and collection can also take place. In addition, a sensor for detecting the upper seaweed aquaculture net 12 is provided in the laver aquaculture fertilizer spraying device 1, and when the sensor detects that the nori aquaculture net 12 exists above, the laver aquaculture fertilizer 4 is applied from the nozzle 5. You may make it spread.

以上に説明したように、上記海苔養殖用肥料散布装置１は、支柱９に昇降自在に吊設した海苔養殖網12に向けて下方から海苔養殖用肥料４を散布するためのノズル５を船体２の前側に設けるとともに、海苔養殖用肥料４を貯留するとともにノズル５から海苔養殖網12に向けて散布した余剰の海苔養殖用肥料４を回収するための上方を開口させたタンク６を船体２の後側に設けた構成となっている。 As described above, the fertilizer spraying apparatus for seaweed cultivation 1 has a nozzle 5 for spraying the fertilizer for seaweed cultivation 4 from below toward the seaweed cultivation net 12 vertically suspended from the column 9 . The tank 6 is provided on the front side of the hull 2 and has an upper opening for storing the fertilizer 4 for cultivating seaweed and collecting the surplus fertilizer 4 for cultivating seaweed sprayed from the nozzle 5 toward the net 12 for cultivating seaweed. It has a configuration provided on the rear side.

そのため、上記構成の海苔養殖用肥料散布装置１では、海苔養殖網12の海苔に所要量の海苔養殖用肥料４を直接散布することができ、海苔養殖用肥料４の効用を十分に得ることができるとともに、海苔養殖用肥料４を無駄に消費してしまうのを防止することができる。 Therefore, the laver farming fertilizer spraying apparatus 1 having the above configuration can directly spray a required amount of the laver farming fertilizer 4 on the laver of the laver farming net 12, and the effect of the laver farming fertilizer 4 can be sufficiently obtained. In addition, wasteful consumption of the manure 4 for cultivating seaweed can be prevented.

また、上記海苔養殖用肥料散布方法は、船体２の前側に海苔養殖用肥料４を散布するためのノズル５を設けるとともに、船体２の後側に海苔養殖用肥料４を貯留するための上方を開口させたタンク５を設けた海苔養殖用肥料散布装置１を用い、支柱９に昇降自在に吊設した海苔養殖網12が海面14から離間している時に、海苔養殖網12に沿って海苔養殖用肥料散布装置１を移動させながら、タンク５に貯留した海苔養殖用肥料４をノズル５から海苔養殖網12に向けて散布し、同時に余剰の海苔養殖用肥料４をタンク６に回収する構成となっている。 Further, in the method for spraying nori-cultivating fertilizer, the nozzles 5 for spraying the nori-cultivating fertilizer 4 are provided on the front side of the hull 2, and the upper part for storing the laver-cultivating fertilizer 4 is provided on the rear side of the hull 2. Using a fertilizer spraying device 1 for laver cultivation provided with an open tank 5, laver cultivation is carried out along the laver cultivation net 12 when the laver cultivation net 12 vertically suspended on a post 9 is separated from the sea surface 14. While moving the fertilizer spraying device 1, the laver aquaculture fertilizer 4 stored in the tank 5 is sprayed from the nozzle 5 toward the laver aquaculture net 12, and at the same time, surplus laver aquaculture fertilizer 4 is collected in the tank 6. It's becoming

そのため、上記構成の海苔養殖用肥料散布方法では、海苔養殖網12の海苔に所要量の海苔養殖用肥料４を直接散布することができ、海苔養殖用肥料４の効用を十分に得ることができるとともに、海苔養殖用肥料４を無駄に消費してしまうのを防止することができる。 Therefore, in the method for spraying the fertilizer for laver farming with the above configuration, the required amount of the fertilizer for laver farming 4 can be directly sprayed on the laver of the laver farming net 12, and the effect of the fertilizer for laver farming 4 can be sufficiently obtained. At the same time, wasteful consumption of the manure 4 for cultivating seaweed can be prevented.

また、上記海苔養殖用肥料散布方法は、ノズル５から海苔養殖網12に向けて散布した余剰の海苔養殖用肥料４が全てタンク６に回収される速度となるように船体２の進行速度を調整する構成となっている。 Further, in the method of spraying fertilizer for laver cultivation, the advancing speed of the hull 2 is adjusted so that all the surplus fertilizer for laver cultivation 4 sprayed from the nozzle 5 toward the laver cultivation net 12 is collected in the tank 6.
