Description

[Detailed description of the invention] This invention involves storing the mother oyster (Akoya oyster), which is the shell of the pearl, before inserting the nucleus for curing the pearl, and submerging it in the sea for about a week to cause ovulation. This invention relates to a cultured pearl egg extractor used for removing cultured pearls.

This type of egg extractor has been known in various configurations, such as bamboo basket-shaped ones and synthetic resin ones.
Bamboo basket-like products have restrictions on the shape and pattern of the holes due to their manufacturing aspects, and even for synthetic resin products, if the shape of the holes can be freely selected, the investment cost for processing will be high. There is a problem in that the holes are bulky and this is reflected in the product cost.Therefore, in conventional products even if they are made of synthetic resin, the shape of the holes and the arrangement pattern of the holes are almost constant.

Therefore, if the tidal current speed in a particular aquaculture area changes, or if the aquaculture area is relocated between places where tidal current speeds originally differ, such as inside a bay and the open sea, the tidal current may change. It is necessary to adjust the speed to a speed suitable for the ovulation effect of the mother oyster, that is, a speed that maximizes the effect of culturing pearls. Therefore, in order to widen the applicable aquaculture area, it is necessary to prepare many types of egg extractors with holes of various shapes and arrangement patterns and use them selectively as appropriate. Many types of egg extractors are required, which increases the total cost associated with pearl cultivation.Furthermore, it is necessary to constantly transport these various types of egg extractors to the culture area, which is inconvenient in transporting and organizing them. there were.

In view of these circumstances, the present invention provides a cultured pearl egg extractor that can easily and economically advantageously adjust speed in response to changes in tidal current speed as described above, and is also extremely convenient for transportation and organization. Have a purpose in what you aim for.

The cultured pearl egg extractor according to the present invention includes a basket container for storing cultured mother of pearl oysters having a large number of through holes in the circumferential side plate and the bottom plate, and a cage container that can be freely inserted into and removed from the container, and the circumferential plate and the basket container have a plurality of holes. A cylindrical tidal flow adjustment device that can be inserted and installed in a state in which the circumferential side plate is opposed to each other with a gap as appropriate, and the numerous through holes formed in the circumferential side plate and the through holes on the basket container side are aligned in position MP. It consists of a combination with a vessel.

In other words, in areas where the tidal current speed is relatively slow, such as in a bay, the impact force of the tidal current on the stored mother mollusk is weak even by using the above-mentioned cage alone, so that the desired ovulation effect can be reliably exerted. be able to.

Therefore, in sea areas where the tidal current speed is naturally high, such as the open sea, or in cases where the tidal current speed has increased due to some reason even in a normally quiet bay, the above-mentioned cage container By inserting and using the above-mentioned tidal current regulator inside the tidal current, the fast tidal current is weakened by contacting the peripheral plate in two stages, in other words, the tidal current speed is reduced.
It can weaken the vitality of the mother oyster and ensure that it ovulates as expected.

As is clear from the above, by simply preparing one tidal flow regulator with the above-mentioned configuration and inserting it into or taking it out of the liquid container as appropriate, it can be used regardless of the tidal flow speed. , you can always expect a good ovulation effect, and therefore, with the economical means of preparing two types of parts,
Not only can they be applied to a wider range of sea areas, but they are also much more convenient to transport and organize.

Embodiments of the present invention will be described in detail below based on the drawings.

In Fig. 1, reference numeral 1 denotes a liquid container for storing cultured mother-of-pearl oysters, which is made of synthetic resin, and its four circumferential side plates 1A and bottom plate 1B have a large number of through holes 2 arranged vertically and horizontally. It is formed in the state.

Reference numeral 4 denotes a bottomless rectangular cylindrical tidal flow regulator that can be inserted into and taken out from the liquid container 1, and as clearly shown in FIGS. 2 and 3, it consists of four plates. It consists of synthetic resin peripheral side plates 4A, and each of these side plates 4A is disassembled by engagement means between a tongue piece 6 integrally projecting from both longitudinal edges thereof and a square hole 7 formed near both longitudinal edges. It is constructed so that it can be freely assembled and transported, or disassembled and transported without taking up much space, and each of the station side plates 4A has a large number of through holes 5, etc. formed in rows and columns in rows and columns.

When the tidal flow regulator 4 is inserted and installed as shown in FIG. 1, the tidal flow regulator 4 is placed between its circumferential side plate 4A and one circumferential plate of the liquid container 1 facing it as shown in FIG. A small gap 3 is appropriately formed in the liquid container 1, and the through holes 5, 2, etc. of the opposing circumferential side plates 4A, IA are arranged so that they can be inserted into the liquid container 1 with the holes 5, 2, etc. There is.

In addition, 8 in the figure is an opening/closing lid.
