There is an application for exception of loss of novelty

The present invention relates to a washing device for aquaculture baskets, and relates to a washing device suitable for use in cleaning aquaculture baskets such as round baskets used for cultivating scallop shells when they are withdrawn from the sea.

In scallop farming, the captured juveniles are raised to a certain size, and then the shells are housed in aquaculture cages such as so-called round cages and Zabton cages, and then grown and caught in the sea.
Aquaculture using a round basket is generally carried out by a multi-stage round basket in which a plurality of round baskets are connected, and the multi-stage round basket has a plurality of outer frames formed in a ring shape having a diameter of about 35 to 50 cm. , The outer frame is formed in a cylindrical shape by a mesh member connected in a bellows shape, and the ring-shaped bottom and top are similarly closed by the mesh member. Each round basket is provided with an opening for inserting and removing shellfish, and the opening is closed with a string for closing when culturing in the sea. In particular, in the multi-stage round basket, the opening of each round basket can be closed and opened with a single string.

Between each adjacent outer frame, a bellows-shaped net-like member is divided into a cylindrical shape of about 30 to 40 cm in the long axis direction in a stretched state, and 10 in one multi-stage round basket. About a number of round baskets are continuously provided. Scallops are housed inside each of these round baskets, and the scallops are cultivated by hanging the integrated multi-tiered round baskets into the sea. After a lapse of a predetermined period, the adult scallops inside the round basket are taken out from the above-mentioned opening and shipped or processed.

Alternatively, it is necessary to increase or decrease the number of scallops to be accommodated according to the growth stage of the scallops. be. This replacement work may be performed multiple times from juvenile to adult.

During the replacement work, the net-like part of the basket is removed from the overgrown seaweed and other organisms, and the basket is washed at the same time. By making it easier to get inside the cage and breathe, it promotes the growth of the contained shellfish. Alternatively, not only the replacement work of shellfish during cultivation but also the cleaning work of the culture cage after fishing is performed to prepare for the next use.

Conventionally, a cleaning device is used for cleaning aquaculture baskets, and as an example of this cleaning device, the invention described in Japanese Patent Application Laid-Open No. 2016-47013 (Patent Document 1) is known. In the device described in the same publication, a nozzle for injecting a water stream is attached to a rotatable head, and the water ejected from the nozzle traverses between the ends in the width direction of the aquaculture cage holding a three-dimensional shape. High-pressure water is sprayed to perform cleaning work.
The invention described in Document 1 is effective in that the entire cleaning device can be miniaturized, so that it can be mounted on a small ship and does not adversely affect the scallops inside the culture cage. ing.

Further, as another cleaning device, Japanese Patent Application Laid-Open No. 2004-24058 (Patent Document 2) discloses an invention relating to a “scallop farming basket cleaning device”. The invention described in the same document 2 is provided with rubber rollers on the lower side and the upper side, respectively, the upper rubber roller is attached by a movable shaft, and the culture cage is sandwiched between the lower and upper rubber rollers, and the pressure is high from above. By spraying water, the deposits on the basket are removed. According to this, it is possible to prevent the cage from being damaged and to efficiently perform the cleaning work because the traveling direction and position of the aquaculture cage are not disturbed during cleaning.

With this configuration, as shown in FIG. 9, when cleaning the aquaculture basket 50, which is the object to be cleaned on the mesh conveyor 14, the water flow A jetted from above and the water flow B jetted from below collide with each other. , It is possible to prevent the situation where the water pressures cancel each other out. Therefore, it becomes possible to maintain a high water pressure required for cleaning the aquaculture cage, and each of the water streams A and B easily penetrates the mesh portion of the aquaculture cage 50 and contributes to the improvement of the cleaning action.
Further, making the rotation diameter R1 of the upper cleaning means 20 larger than the rotation diameter R2 of the lower cleaning means 30 causes dust and the like once lifted upward by the lower cleaning means 30 to approach the outlet side of the cleaning zone. As the water flow A jetted from the upper cleaning means 20 acts to drop downward, it is possible to prevent the deposits from remaining and further enhance the cleaning effect.

In addition, as shown in FIGS. 8 and 9, the separation distance α between the nozzle 22 and the nozzle 32 is preferably set to about 5 mm to 30 mm. The optimum value of the separation distance α depends on the water injection angle at each nozzle 22 and 32 and the vertical distance h between the nozzles 22 and 32, but when viewed locally at the position of the network conveyor 14, each The water flows A and B are set so as not to collide with each other and the distances between the water flows A and B of the nozzles 22 and 32 are not too far apart.
Each of the water flows A and B forms a conical, fan-shaped, or linear water flow starting from the tip of the nozzle 22 and the nozzle 32, and at a position where the water flows A and B reach the net conveyor 14. If the water streams A and B are too far apart, the cutting action (shearing action) on the foreign matter adhering to the culture cage 50 is weakened. Therefore, in the present embodiment, the separation distance α is set so that the water flows A and B of the nozzles 22 and 32 do not interfere with each other and are not too far apart. This makes it possible to surely wash away the deposits of the aquaculture basket 50.

Further, the rotation direction Q1 of the nozzles 22, 22 ... In the upper cleaning means 20 is set to be opposite to the rotation direction Q2 of the nozzle nozzles 32, 32 ... In the lower cleaning means 30. That is, since the nozzles 22 and 32 of the upper cleaning means 20 and the lower cleaning means 30 rotate, the water pressure to be sprayed causes the object to be cleaned to generate a rotational force associated therewith, but by reversing the rotation direction. , The rotational forces cancel each other out. For this reason, in combination with the holding force of the conveyor retainer 28 described above, it is possible to prevent inadvertent movement or displacement of the aquaculture basket during transportation on the mesh conveyor 14, so that the cleaning work can be performed efficiently. do.

According to the present embodiment configured as described above, the aquaculture cage 50 on the network conveyor 14 is cleaned by injecting high water pressure cleaning water from above and below by the upper cleaning means 20 and the lower cleaning means 30. Therefore, it is possible to perform the cleaning work efficiently and with a small amount of unwashed residue in a short time.
In addition, since the net conveyor 14 is moving and water is evenly sprayed from the vertical direction onto the aquaculture basket, which is the object to be cleaned, the work of removing dirt and deposits adhering to the aquaculture basket is surely performed. Can be done.

In the present embodiment, the rotary heads 24 and 34 in the upper cleaning means 20 and the lower cleaning means 30 are installed on the same vertical line, but the lower cleaning means 30 is installed on the entrance side in the cleaning zone and the upper part is installed. The cleaning means 20 may be installed so that the rotation centers of the rotary heads are located at different positions, such as by installing the cleaning means 20 on the outlet side of the cleaning zone.
In this case, the lower surface of the aquaculture basket is first washed by the lower washing means, and then the upper surface is washed by the upper washing means, but the washed water can be reliably received by the lower casing.

INDUSTRIAL APPLICABILITY The present invention can be used in the fields of fishery and fishery processing, which are engaged in shellfish aquaculture business.
