Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a bait casting device for dispensing bait to fish and shellfish in a cage, and particularly to a bait casting device for dispensing bait to fish and shellfish in a fish cage, and particularly to a bait casting device for dispensing bait to fish and shellfish in a fish cage at a remote location in a culture cage moored on the sea away from the shore. The present invention relates to a bait casting device suitable for bait casting.

[Conventional technology]

Fish and shellfish are cultivated inside cages that are enclosed in the sea or rivers.

As an example of this kind of cage, there is a structure in which a plurality of rod-shaped buoyant bodies are connected with joints to form a polygonal cage frame, and a rope is suspended from the cage frame in Japanese Patent Laid-Open No. 62-1077.
34 etc.

The cage frame is moored at a fixed position with an underwater anchor using a rope connected to the joint, and can be sailed to another location by boat or the like if necessary.

Some of the above-mentioned cages have a circumscribed circle with a diameter of 100 m, for example, in order to improve the efficiency of aquaculture.

Fish feed such as raw fish, moist pellets, and dry pellets are used for fish and shellfish farming, but conventionally,
As mentioned above, there are three ways to feed the fish and shellfish in the cage: scooping the food with a shovel and spreading it manually, using a proa and spreading it on the airflow, and spreading by pulling one end of the conveyor belt into the cage. The method used was either to run a pipe into the tank and pump it along with seawater.

[Problem that the invention seeks to solve]

However, in the above-mentioned conventional bait casting method, a feeding boat loaded with bait must come alongside the cage frame, or a person must transfer onto the cage frame to carry out the bait casting operation. If the feeding boat leaves the cage frame during feeding operations, it will no longer be possible to cast bait, so it was necessary to secure the feeding boat to the cage frame with a fastening net or the like.

Also, when the sea was rough, it became impossible to bring the feeding boat alongside the fish tank, making it impossible to cast bait.

Furthermore, it was not possible for one feeding boat to simultaneously feed multiple Isuke.

Furthermore, it was difficult to spread the bait uniformly over a wide area.

[Means for solving problems]

The present invention was developed in view of the problems of the prior art described above, and it is possible to administer bait from a distance even when it is impossible to come alongside the cages due to rough weather, and moreover, it is possible to administer food to multiple cages from a single boat. It is an object of the present invention to provide a bait casting device into a cage that can simultaneously administer bait and improve the operating rate and save labor in bait casting work.

The present invention provides a mooring line consisting of a rope guided from a fish tank near the water surface, a feeding pipeline that is anchored in the middle of the mooring line and guided into the fish tank, and a tip of the feeding pipeline inside the fish tank. A feeding boat is moored to the mooring line, and feed is spread from the feeding boat into the cage via the feeding pipeline, thereby achieving the above object. It is.

〔Example〕

The present invention will be specifically described below with reference to the drawings.

FIG. 1 is a plan view of a bait casting device into a cage according to an embodiment of the present invention, and FIG. 2 is a side view of the bait casting device of FIG. 1.

In Figures 1 and 2, a fish tank 1 for cultivating fish and shellfish is moored offshore in the sea or a river.
A mooring line 2 consisting of a rope guided along near the water surface to a position away from the cage 1 is laid, and further,
A feeding pipeline 3 is provided which is moored in the middle of the mooring line 2 and guided into the fishery 1.

Note that line W in FIG. 2 indicates the water surface.

A spreading head 4 is connected to the tip of the feeding pipeline 3 inside the cage 1 for spreading the feed that is pumped in together with the seawater, and the spreading head 4 is stretched between the feeding pipeline 3 and the cage frame 5. It is moored in a vertical position approximately at the center of the cage l by three locking ropes 24.

Although various structures can be adopted as the fish tank 1, the one shown in the figure has a plurality of (for example, six) rod-shaped buoyant bodies 1.
1 are connected by a joint 12 to form a polygonal (for example, regular hexagonal) cage frame 5, and a rope 14 with a bottom is suspended from the cage frame 5.

This fish tank 1 has a rope 15A connected to the joint 12.
and is moored in place with an underwater anchor 15.

As shown in the figure, the mooring line 2 is arranged between the mooring buoy 17 moored with a row 116A connected to an underwater anchor 16 and the fish tank 1, and a buoyancy buoy 18 is provided in the middle of the mooring line 2. are combined.

In the illustrated example, the feeding pipeline 3 is supported by the mooring line 2, and is further guided into the fish tank L via a relay pipe 19 fixed to the cage frame 5 (in the illustrated example, the buoyant body 11). There is.

FIG. 3 shows the specific structure of the spray head 4. As shown in FIG.

In FIG. 3, the dispersing head 4 is provided with a diffusion core 22 having a conical surface at the tip opening of a discharge pipe 21, and the base end of the discharge pipe 21 is connected to the feeding pipeline 3. The structure is such that bait is pumped together with seawater through the cage and is guided by the diffusion core 22 and spread evenly over a wide area.

As shown in FIG. 3, an appropriate number (for example, three) of buoys 23 are connected to this scattering head 4, and these buoys 2
3 to which the locking rope 24 is connected.

FIG. 4 is a side view illustrating the specific structure of the mooring buoy 17.

In Fig. 4, the mooring buoy 17 has a marker light 27 with a power source 26 attached to the top surface (above the water surface) of the buoy body 25, which is a vertical cylindrical sealed hollow body, and a marker light 27 with a power source 26 is attached to the bottom surface (below the water surface). A weight 28 for use is attached.

1 and 2, the feeding pipeline 3
is made of an elastic hollow pipe made of rubber or PVC, and if necessary, it can be constructed of a floating hose with a buoyancy material such as urethane foam provided around it.

Feeder 31 consisting of a pump etc. that pumps bait together with seawater
The feeder 32, which is equipped with a feeder and feeds loaded bait under pressure, can be easily anchored to the mooring line 2 by well-known means.

Further, a tip hose 3 is provided at the other end of the feed pipeline 3, that is, on the side of the feeder 32 that is anchored to the mooring line 2.
A is connected to the tip hose 3A, and a coupler connectable to the feeder 31 is provided at the other end of the tip hose 3A.

When feeding the fish and shellfish in the fish tank 1, the feeder 32 is anchored to the mooring line 2, and the end of the feeding pipeline 3 (in the illustrated example, the tip hose 3A) is taken up onto the ship and prepared inside the ship. The feeding pipeline 3 is connected to a feeder 31, and the feeder 31 allows feed to flow through the feeding pipeline 3.

In this case, the feeder 31 is usually of the type of a feeding pump that pumps the bait together with seawater, and continuously pumps the loaded bait through the feeding pipeline 3 and from the spray head 4 in the center of the fish tank 1. It works to scatter around the area.

When feeding is finished, the feeding pipeline 3 is removed and the mooring line 2 is unlatched, allowing the vessel to move elsewhere.

FIG. 5 shows one feeder 32 using the bait casting device of the present invention.
1 schematically shows a situation in which bait is simultaneously cast into a plurality of (three in the illustrated example) cages l.

In Figure 5, there are multiple (3) fish tanks in the same water area.
are moored, a mooring line 2 is laid from one of them, and in the middle of the mooring line 2 there are multiple (3) feeding pipes led to each of the multiple (3) cages 1. Line 3 is locked.

The plurality of (three) feeding pipelines 3 are connected to a feeder 31 provided in a feeder 32 moored to the mooring line 2, and by operating the feeder 31, the plurality of (three) The bait can be simultaneously (or sequentially) dispersed and administered from each of the dispersion heads 4 in the cage 1.

According to the embodiment described above, the following effects were obtained.

1) Place feeder 3 on mooring line 2 away from cage 1.
Since bait is cast by mooring fish tank 2, even when the sea is rough and the feeder 32 cannot be placed alongside fish tank 1, it becomes possible to cast bait easily.

For this reason, the bait casting operation rate was improved, and a bait casting device into the pen that did not inhibit the growth of fish and shellfish was obtained.

1i) If the feeding pipelines 3 are individually routed from one mooring line 2 to a plurality of cages 1, one feeder can easily feed a plurality of cages 1 simultaneously or sequentially. We were able to feed the animals and save labor.

iii) Since the bait is cast using the scattering head 4 moored to the center of the cage 1, it has become possible to evenly administer the bait over a wide area.

〔Effect of the invention〕

As is clear from the above description, the device for casting bait into a fish tank of the present invention has a mooring line consisting of a rope guided from the fish tank near the water surface, and a mooring line that is moored in the middle of the mooring line and is attached to the fish tank. a feeding pipeline guided into the cage, and a dispersion head connected to a tip end of the feeding pipeline inside the cage, a feeder is moored to the mooring line, and a feeder is connected to the mooring line from the feeder through the feeding pipeline. Since the structure is such that the bait is scattered inside the cage, bait can be cast even when the sea is rough, and one boat can cast bait to multiple cages at the same time or sequentially. Thus, a device for casting bait into a cage can be obtained, which can improve the operating rate of bait casting and save labor.
