Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for separating juvenile shellfish from a seedling device, for example, for detaching juvenile shellfish grown from a seedling device for growing larvae (larva) of scallops to grow into juvenile shellfish.
[0002]
[Prior art]
For example, scallops are cultured as follows. Around the May, when the fertilized egg becomes a larva and floats in the water, a net-type seedling device is suspended in the water. Although the seedling device has different forms and materials depending on the culture area, the seedling device targeted by the present invention consists of a net bag, and when hanging in water, the net outer bag has a finer mesh than the seedling device. It is to be housed and used. When the larvae reach a certain size, they attach to the seedling device and grow into juveniles. When the larvae grow to a size of 10 to 15 mm, the seedling container is lifted and collected, and the larvae are detached from the seedling container. Collected juvenile shellfish are selected according to their degree of growth, and strong juvenile shellfish are dispersed in small amounts in bellows bowls, etc., and the bellows bowls are suspended in the sea for wintering. When the larvae grow to a size of about 40 mm, collect the bellows bowls, take out the larvae, disperse them into the sea and grow them for several years.
[0003]
[Problems to be solved by the invention]
The work of removing the juveniles attached to the seedling device in the aquaculture process described above is carried out by the operator holding the seedling device in his hand and shaking, but the seedling device has a length of about 1000 mm. There is a problem that the weight of the worker itself is heavy, and the weight is further increased when a large amount of larvae are attached, which is a heavy burden on the worker, and therefore the work efficiency is poor. Moreover, since it is difficult to shake the seedling container sufficiently, there is a drawback that the young shellfish remain without being detached.
[0004]
Further, a method for separating juveniles from a seedling device by water pressure and a method for separating juveniles from a seedling device by a rotating brush are known. However, the separation method using water pressure has the disadvantage that the larvae are damaged, and the separation method using the rotating brush has the disadvantage that the seedling device is entangled with the brush. And until now, no automated means has been proposed for detaching juveniles from a seedling device using mechanical power.
[0005]
The present invention has been made in view of the above-mentioned unsolved problems of the prior art, and since the operation of removing the juvenile from the seedling device is mechanically performed, a large amount of processing is possible and the burden on the worker is greatly increased. Another object of the present invention is to provide a separation apparatus for larvae from a seedling device that can reduce the amount of the larvae and is excellent in work efficiency without leaving the larvae.
[0006]
[Means for Solving the Problems]
The means of the present invention configured to solve the above-described problems includes a seeder moving mechanism that moves the net seedling seeder from the front side to the rear side in a state where the net seedling seeder is detachably suspended, and the harvester. It comprises a seedling device swinging mechanism for dropping the juvenile shell attached to the seedling device by swinging the seedling device moved by the seedling device moving mechanism from the side.
[0007]
The seedling device moving mechanism includes a base body, an endless transfer body that is wound around a rotary body that is pivotally supported separately from the front side and the rear side of the base body, and is rotationally driven by a drive source, and the endless transfer It is good to comprise from the some latching pin which protrudes in the body at predetermined intervals along the rotation direction, and supports the said seedling device so that engagement / disengagement is possible.
[0008]
The seeder moving mechanism may be provided with seeder detachment means for detaching the seeder after being swung by the seeder oscillating mechanism and dropping the young shellfish.
