Description

  The present invention relates to a cleaning method of a round cage for shellfish cultivation (hereinafter simply referred to as “round cage”) and a cleaning device for a round cage.

  One method for cultivating shellfish such as scallops and oysters is to place small shellfish in a round cage (for example, the one shown in FIG. 1 of Patent Document 1) and suspend them in the sea for cultivation.

  During aquaculture, a large amount of marine organisms, other garbage, and dirt (hereinafter simply referred to as “garbage”) adhere to the round cage. The adhesion of dust is not preferable for the growth of shellfish. For this reason, it is common to raise a round basket from the sea in the middle of aquaculture, wash the round basket, drop the trash, and then put it in the sea again for cultivation. Shellfish that have grown until they can be shipped are lifted from the ocean and taken out of the cage. Also in this case, since dust is often attached in large quantities, it is usual to remove the dust by washing the round basket before taking it out.

  The cleaning of the round basket, which has been performed conventionally, is performed by a cleaning apparatus A as shown in FIG. The cleaning device A in FIG. 4 is configured such that the roller table B or the endless belt circulates and rotates in the case F, and includes an upper nozzle C and a lower nozzle D. A round basket E with shells pulled up from the sea is placed on the roller table B, stretched laterally, tilted and folded, and high pressure water is sprayed onto the round basket E from the upper nozzle C and the lower nozzle D. The dust is washed away.

JP 2017-035077 A

  In the conventional cleaning method, high-pressure water is sprayed not only on the round basket but also on the shells inside, so shells may die, and the yield of aquaculture decreases.

  The problem to be solved by the present invention is to provide a round basket cleaning method and a round basket cleaning apparatus which can wash off dust without killing the shellfish even if high pressure water is sprayed onto the round basket. With the goal.

  The method for cleaning a round basket of the present invention is to place a round cage with shells pulled up from the sea horizontally on a ship, extend it into a cylindrical shape in the horizontal direction and bring the shells to the lower side in the round basket. Avoid this shell, spray high-pressure water on the upper side of the round cage, wash away the dust adhering to the round cage, and rotate the round cage at an appropriate angle in the circumferential direction. After moving to the lower side of the inside, the high pressure water is sprayed on the upper side of the round basket to wash away the dust adhering to the round basket, and the round basket is rotated by repeating the rotation of the round basket and the high pressure water as many times as necessary. This is a cleaning method.

  In the round basket cleaning method, the round basket can be placed on the deck of the ship or on a cradle installed on the side of the ship and stretched in a cylindrical shape in the horizontal direction and rotated on them. When dropping dust on a cradle installed on the side of the ship, it is possible to wash the dust into the sea while washing. While moving the nozzle in the longitudinal direction of the round basket, the entire length in the longitudinal direction of the round basket can be washed. The number of nozzles can be one or more than two. The nozzle can be stopped or temporarily stopped at any point while moving, and high pressure water can be sprayed while swinging or rotating 360 degrees in any direction. The round basket can be rotated by a machine or manually.

  The cleaning apparatus for a round basket of the present invention includes a nozzle that injects high-pressure water into a round cage that is pulled up from the sea and stretched horizontally on a ship and is installed in a cylindrical shape, and a rail that is installed in the lateral direction of the round basket And the nozzle is mounted so as to be capable of reciprocating along the rail. It is also possible to provide a cradle on the shore side of the ship on which a round basket lifted from the sea can be placed.

The method for cleaning a round basket of the present invention has the following effects.
(1) Extend the round cage with shells raised from the sea into a cylindrical shape in the horizontal direction, bring the shells to the lower side of the round basket, avoid the shells, and supply high-pressure water on the upper side of the round cage. Because it sprays, shellfish do not die.
(2) Since the round basket is rotated in the circumferential direction and the high-pressure water is sprayed on the upper side of the round basket as many times as necessary, the dust around the entire circumference of the round basket can be washed.
(3) If the round cage with shells raised from the sea is placed on the cradle on the side of the ship and washed, the garbage can be washed off into the sea, making it difficult for the ship to become dirty. Cleaning becomes easier.
(4) Since the nozzle is moved in the longitudinal direction of the round basket, the entire longitudinal direction of the round basket can be cleaned.
(5) If high-pressure water is jetted while the nozzle is swung or rotated, the entire round basket can be efficiently washed.

  According to the round basket cleaning apparatus of the present invention, since the nozzle reciprocates in the longitudinal direction of the round basket, the cleaning can be performed automatically and efficiently.
