Description

  The present invention relates to a method of cleaning a round basket for shellfish culture (hereinafter simply referred to as a “round basket”) and a round basket cleaning apparatus.

  One of the methods of culturing shellfish such as scallops and oysters is a method in which small shellfishes are put in a round basket (for example, shown in FIG. 1 of Patent Document 1) and suspended in the sea for aquaculture.

  During aquaculture, round cages accumulate large amounts of marine organisms, other garbage, and dirt (hereinafter simply referred to as "garbage"). The attachment of dust is not preferable for the growth of shellfish. For this reason, it is common to pull up the basket from the sea during the cultivation, wash the basket, remove dust, and then re-enter the sea for cultivation. In addition, shellfish that have grown until they can be shipped are taken out of the round basket by pulling the round basket out of the sea. Also in this case, since a large amount of dust is often attached, it is usual that the round basket is washed to remove the dust before being taken out.

  Cleaning of a round basket, which has been performed conventionally, is performed by a cleaning apparatus A as shown in FIG. 4 is configured such that a roller table B or an endless belt circulates and rotates in a case F, and includes an upper nozzle C and a lower nozzle D. A round basket E containing shells raised from the sea is placed on a roller table B, stretched sideways, folded down obliquely and folded, and high-pressure water is sprayed from the upper nozzle C and the lower nozzle D onto the round basket E. Washing the garbage.

JP 2017-035077 A

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

  The problem to be solved by the present invention is to provide a method for cleaning a round basket and a device for cleaning a round basket in which high-pressure water is sprayed on a round basket and the dust is not sprayed on the shells and dust can be washed off without killing the shellfish. With the goal.

  In the method for cleaning a round basket of the present invention, a round basket containing shells pulled out of the sea is placed horizontally on a ship, stretched in a horizontal direction into a tubular shape, and the shells are brought to the lower side in the round basket. Avoiding the shellfish, spray high-pressure water on the upper side of the round basket to wash away the dust attached to the round basket, and then rotate the round basket appropriately in the circumferential direction to rotate the shell into the round basket. Then, high-pressure water is sprayed on the upper side of the round basket to wash away dust attached to the round basket, and the round basket is rotated and sprayed with high-pressure water as many times as necessary to remove the round basket. This is a cleaning method.

  In the method for cleaning a round basket, the round basket can be placed on a deck of a ship or on a cradle installed on the side of the ship, stretched in a laterally long direction into a tubular shape, and rotated thereon. When the dust is dropped on a cradle installed on the side of the ship, the dust can be washed down into the sea while washing. While moving the nozzle in the longitudinal direction of the round basket, the entire length of the round basket in the longitudinal direction can be cleaned. The number of nozzles can be one or two or more. The nozzle may be moved or stopped or stopped at an arbitrary position, and the high-pressure water may be sprayed while swinging or rotating in any direction of 360 degrees. The rotation of the round basket can be performed by a machine or manually.

  The round basket washing device of the present invention is a nozzle that injects high-pressure water to a round basket that is pulled up from the sea and stretched horizontally on a ship in a horizontal direction, and a rail installed in the horizontal direction of the round basket. And the nozzle is provided so as to be able to reciprocate along the rail. A cradle on which a round basket raised from the sea can be placed may be provided on the side of the ship.

According to the method for cleaning a round basket of the present invention, the following effects can be obtained.
(1) A shell-filled round basket withdrawn from the sea is stretched cylindrically in the horizontal direction, and the shells are moved to the lower side of the round basket. Then, high-pressure water is placed above the round basket to avoid the shells. The shellfish do not die because they are sprayed.
(2) Since the round basket is rotated in the circumferential direction and the high-pressure water is sprayed onto the upper side of the round basket as many times as necessary, dust on the entire circumference of the round basket can be washed.
(3) If the round basket with shells raised from the sea is washed on a cradle installed on the side of the ship, the garbage can be washed off into the sea. 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) By injecting high-pressure water while swinging or rotating the nozzle, the entire round basket can be efficiently cleaned.

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

It is the round basket in this invention, (a) is a longitudinal front view, (b) is a perspective view which shows a bottom net and a support frame, (c) is XX sectional drawing in (a).

An embodiment of a round basket cleaning method and a round basket cleaning device of the present invention will be described with reference to the drawings. In the description of this embodiment, the configuration of the round basket will be described, and then the round basket cleaning device and the round basket cleaning method will be described in this order.

[Round basket for shellfish culture]
A general configuration of the round basket 2 will be described with reference to FIGS. The round basket 2 is a general-purpose round basket, and includes a net cylindrical body 3, a plurality of supporting frames 5 having a bottom net 4, and a plurality of hanging ropes 6. The net cylinder body 3 is a seawater-resistant and weather-resistant elongated round net material, and a pair of long sides of the net material are closed by a string 7 to form an elongated cylindrical shape. Space). The support frame 5 includes an annular frame member 5a and a reinforcing member 5b provided in a plus shape inside the annular frame member 5a. The bottom net 4 is a sea-water- and weather-resistant circular net material, is superposed on one surface of the support frame 5, and has a peripheral portion connected to the annular frame material 5a by a string. Further, four hanging ropes 6 are vertically applied to four places in the circumferential direction of the outer surface of the net cylindrical body 3 to be fixed to the support frame 5 together with the net cylindrical body 3, and the upper ends of the four hanging ropes 6 are put together. The upper binding portion 6a and the lower binding portion 6b which collectively connect the lower ends thereof are suspended portions.

[Circular basket cleaning device]
As shown in FIGS. 2 and 3, the cleaning device 1 includes a cradle 11 installed on the shore side G of the ship S, and a cradle at a position higher than the cradle 11 on the inner side of the shore side G and the cradle 11. A rail 15 is provided along the rail 11, and a nozzle 16 is provided so as to be able to reciprocate along the rail 15.

  The pedestal 11 is made of stainless steel or an engineering plastic material having seawater resistance, weather resistance and durability, for example, glass fiber, and is long enough to support the longest round basket 2. The cradle 11 has a mounting portion 12 fixed to the side G of the ship S and a receiving portion 13 on which a round basket is placed. The mounting portion 12 can be mounted on the ship by bolting or other fixing means. The shape of the receiving portion 13 is not limited, as long as the receiving portion 13 can place the round basket 2. For example, the receiving portion 13 is an elongated plate, an elongated plate that curves upward, and the like. This is preferable because the washed dust easily falls into the sea. The cradle 11 fixed to the side G can be folded from the horizontal state to the lower side of the side G, so that it is not obstructed when not in use.

  The rail 15 has a length corresponding to the pedestal 11, and is suspended along the pedestal 11. The rail 15 is spaced apart from the side of the cradle 11 when the round basket 2 is placed on the cradle 11 in a horizontally long state. The rail 15 is supported by support legs (not shown).

  The nozzle 16 is detachably attached to a slider 17 guided by a rail 15 with a certain degree of freedom. Here, the slight degree of freedom means that the slider 17 is supported so that there is a play in which the nozzle 16 can be touched and moved so as to change the radiation direction of the nozzle 16 by grasping the handle portion of the nozzle 16 on the high pressure water inlet side. That is being done. The number of nozzles 16 may be one or two or more. In the case of a plurality of nozzles, the nozzles 16 are connected in series, and if one nozzle 16 is operated, all the nozzles 16 can be operated integrally. The nozzle 16 can be swingable or rotatable.

  The plurality of nozzles 16 are provided so as to move integrally, so that the plurality of nozzles 16 simultaneously move along the rail 15 in the same direction. As a means of movement, it is sufficient that the movement is performed manually by a fisherman on a boat, but a mechanical device may be provided. The speed of the nozzle 16 can be adjusted so that the moving speed is slow when there is a large amount of dust attached to the round basket, and the moving speed is fast when the dust is small. Decreasing the moving speed makes it easier to remove dust. The adjustment of the moving speed can be performed automatically or manually. In the case of automatic measurement, various types of sensors such as laser type and ultrasonic type are provided, and measurement signals such as laser light and ultrasonic waves are projected from the sensors onto a round basket, and dust is automatically generated based on a reflected signal from the round basket. The moving speed can be automatically adjusted based on the detection result. In this case, it is preferable that the sensor be provided ahead of the nozzle 16 in the movement direction so that dust can be detected prior to the cleaning by the nozzle 16.

[Round basket cleaning method]
In the method for cleaning a round basket according to the present embodiment, the round basket 2 containing shellfish is pulled up from the sea onto the ship S or the cradle 11, and the round basket 2 is stretched in the horizontal direction to form a cylindrical shape. After the shells inside the basket 2 are moved downward in the round basket 2, high-pressure water is sprayed from the nozzle 16 to the upper side of the basket 2 avoiding the shells. The round basket 2 is rotated by an appropriate angle in the circumferential direction so as to bring the shellfish to a lower side in the round basket 2 and then inject high-pressure water onto the upper side of the round basket 2 so as to be repeated a required number of times. When the injection from the nozzle is performed from the ship side to the sea side, the garbage washed off from the round basket 2 placed on the cradle 11 falls into the sea.

  Washing is performed while moving the nozzle 16 in the longitudinal direction of the round basket 2 to wash the entire round basket 2 from one end to the other. The number of nozzles can be one or two or more. Injecting high pressure water while swinging or rotating left, right, up and down or 360 degrees in any direction while the nozzle 16 is moving, paused during movement, or stopped at a predetermined position without moving Can be. The round basket 2 can be rotated by a machine or manually in a state where it is extended in the horizontal direction. The jet of high-pressure water from the nozzle 16 is always avoided while avoiding shellfish in the round basket 2 so as not to hit the shellfish.
