DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a basket for culturing shellfish such as scallops.

[0002]

2. Description of the Related Art Scallops are placed in aquaculture cages, and the cages are cultivated by hanging them in the sea in multiple stages as shown in FIG. 6, but as they grow up, the scallops need to be transferred to cages with a coarse mesh.

[0003] As shown in Figs. 4 and 5, the culturing cage is provided with a square mold holding frame 2 at the inner bottom of a basket 1 formed of a pentahedral net in a suspended state. The culture cage is
Open the mouth 3 for putting shells in and out of the ridgeline of the basket,
The binding portion 4 is passed over the facing edges 3a and 3b for the mouth so as to close the mouth.

Accordingly, in order to put a shell into a basket, the binding string 4 is pulled out, the mouth is opened, and the shell is put into the basket from the opened mouth, and the basket with the shell is again bound at the opposite edge of the mouth. The mouth is closed through 4.

In order to take out the shell from the basket, the binding is pulled out and the mouth is opened. In any case, opening and closing the mouth takes time and labor. Transferring shells to and removing them from baskets is a very laborious and time-consuming task.

[0006] To ship shellfish of about 1 ton per day, 100
It is necessary to pull up the 0th basket from the sea, pull out the binding string one by one, and open the mouth of the basket, which takes time, and the freshness of the shellfish becomes a problem. In addition, since the binding string is pulled out or passed through, human labor is required for this, and the man-hours for putting in and out the shellfish become large.

[0007]

SUMMARY OF THE INVENTION The object of the present invention is to provide a shellfish cultivation basket in which the above-mentioned problems are eliminated, the shellfish can be taken in and out quickly, and the man-hour required for the operation can be reduced.

[0008]

In order to achieve the above object, the shellfish cultivation basket according to the present invention is provided with a mold-retaining frame at the bottom, and is formed into a pyramid shape such as a pyramid or a cone in a suspended state. Ri Na from network member eggplant, yet have a tether for hanging on the top and bottom
Mouth for closing one ridge portion of the cage to form you, one rim of the left and right opening edges forming the mouth section is stopped before alignment relative to its other rim of the top of the The lower edge is stopped rearward with respect to the other edge so that the right and left edge portions cross each other on the opposite sides in the upper and lower portions and overlap each other.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described below with reference to the case of a scallop cultivation basket shown in FIGS. In FIG. 1, reference numeral 1 denotes a basket formed of a pentahedron-shaped net in a suspended state, and a square mold holding frame 2 is provided on the inner bottom. The upper tether 5 consisting wheel hook on top the basket 1
a, a string 5b for lower linkage is also hung on the bottom ,
The upper and lower connecting cords 5a and 5b are constituted by a single cord 5 that passes vertically through the basket, and the lower part of the cord is connected to the mold retaining frame 2 and hangs down as a linking cord.

[0010] A conventional mouth 3 for opening and closing shells is provided at one ridge of the culture basket as shown in Fig. 5, but in the present invention, left and right rims 3a, 3b forming the mouth are provided. , One right edge 3b, for example, stops its upper part forward with the upper part of the other left edge 3a, and its lower part rearward with the lower left edge. In this case, the left and right lip portions cross each other on the opposite sides in the upper and lower portions so as to overlap each other.

That is, as shown in FIG. 2, the upper right body is in front of the upper left body in front of the right upper body, while the lower left body is in front of the lower right body in front of the lower right body. Reference numerals 6a and 6b in the drawings denote stoppers made of a vinyl-coated metal wire for front alignment and rear alignment. The net is preferably made of a wire material such as nylon which is slightly rigid. In addition, each connecting string of the upper and lower part
It is for hanging up and down multiple stages.

Although the above description has been given of the case of the scallop, the cultivation basket can be used not only for the scallop but also for culturing other shellfish.

[0013]

The above-mentioned cultured basket of the present invention is composed of a standing cone-shaped basket made of a net, and has a mouth 3 for opening and closing a shell at one ridge line. , So that the upper part of one lip 3a is aligned with the upper part of the other lip 3b, and the lower part is aligned with the lower part of the other rim. Since the left and right front bodies are inverted and cross over each other in the upper and lower parts, they are overlapped, so in the state where the shell is put inside and hung, the left and right timepiece parts will be affected by the load on the basket They are tightly fitted and the mouth is closed, and the shell inside cannot escape to the outside of the cage, and the shells can be cultured in the cage.

[0014] In order to take out the shell inside the basket, a right-handed person can easily take out the shell inside the basket by putting his hands between the upper right and left bodies of the basket. Yes, you can also open the upper left and right view and put the shellfish in the basket. If you are a left-handed person, you can put your hand between the left and right body at the bottom of the basket to put the shell in and out.

Therefore, the basket according to the present invention has the following advantages. (a) There is no need to remove the binding string 4 and open the mouth of the basket as in the prior art when putting the shell in and out. Also, if the hand is pulled out from between the right and left viewing points, the mouth of the basket overlaps naturally at the right and left viewing points, so that there is no need to close the mouth through the binding string 4 as in the related art. (b) Therefore, it is possible to easily and quickly transfer the shellfish to and from the basket. (c) As a result, a decrease in freshness of the shellfish can be prevented as much as possible, and the number of workers can be reduced, so that the number of steps for putting and removing the shellfish and collecting the shellfish can be reduced. (d) The basket is suitable for both right-handed and left-handed workers with open / close mouth, and is easy to use.
