Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a facility for preventing breakage of a cultured fish cage, mainly scallops, during washing.

[0002]

[Prior art]

 Shellfish such as scallops, oysters, and pearl oysters have been cultivated in the past, and cultivation baskets for scallops are cylindrical with a multi-layered metal frame coated with polyvinyl chloride, etc., with a net made of nylon or the like, with each step having a bottom. Each of them is used in the form of a round basket or a square metal frame in which the same kind of net is stretched in a pyramid shape and connected in a vertical direction (square basket). In the case of scallop, cultivation cages are used in several stages according to their growth.However, since they are left in the sea for a long period of several months or more, plankton adheres to the net yarn and other organisms grow depending on the growth. Adhere to. Depending on the length of time they are kept in the sea, rice oysters, oysters, fujitsubo, coral, etc. often adhere. These deposits impede water permeability and prevent the scallop from obtaining food and oxygen. Therefore, it is necessary to remove these deposits at a certain period during aquaculture, including at the start of aquaculture.

[0003] In the early days, a cultured basket was left in the sea for a long period of time, so that there were many hard objects such as fujitsubo, coral and the like, and hitting with a hammer was performed to remove these. It was extremely complicated and labor-intensive.

[0004] Thereafter, as a washing device for a cultivation basket for shellfish, mainly scallops, a plurality of rotating rollers arranged side by side in parallel on a horizontal surface are pressed by a spring toward the rotating rollers. A push-rotating roller is installed opposite to the roller, and the farming car is constructed so that it is bitten and transported by both rollers sequentially. In such a case, a deposit is crushed by a pressing rotary roller, and the crushed deposit is washed away by high-pressure water spraying, which has been proposed by Japanese Patent Publication No. 54-15838. There is a problem that the culture basket is easily damaged during washing.

[0005]

[Problems to be solved by the invention]

 The purpose of the present invention is to provide a facility that can prevent damage to the culture cage when washing the culture cage for shellfish, mainly scallops.

[0006]

[Means for Solving the Problems]

 Here, the present inventor supplies a culture car between a plurality of sets of opposed fixed shaft rubber rollers and a movable shaft rubber roller, and injects high-pressure water through a nozzle that reciprocates from above the culture cage. In a washing machine for shellfish cultivation cages for removing adhering substances, first, a movable shaft rubber roller is given its own weight enough to bite the cultivation cage and is suspended by a spring. We found a facility to prevent damage to shellfish culture baskets.

Second, a culture cage is supplied between a plurality of sets of fixed shaft rubber rollers and movable shaft rubber rollers opposed to each other, and high-pressure water is jetted from nozzles reciprocating from above the culture cage. In a shellfish car cage cleaning device that removes extraneous matter, a wire mesh conveyor is placed close to each rubber roller on the farming car transfer surface between the entrance of the farming car and the first rubber roller. Combined with a carry-in auxiliary roller, a required number of wire mesh bridges are provided on the other transfer surface in close proximity to each rubber roller, and a facility for preventing damage to the shellfish culture basket during cleaning has been found. Was.

[0008]

[Embodiment of the invention]

 The equipment for preventing breakage of shellfish culture baskets during washing according to the present invention is conventionally provided by supplying a culture cage between a plurality of sets of fixed shaft rubber rollers and movable shaft rubber rollers opposed to each other, and from above the culture basket. This is an improved shellfish cage cleaning system that removes deposits by injecting high-pressure water with a reciprocating nozzle.The first idea is to move the cage into a movable shaft rubber roller. An own weight (approximately 65 kg) was applied, and this was hung by a spring, and was moved up and down in accordance with the thickness of the cultivation basket overlap. Here, the reason why the movable shaft rubber roller is not pressed by a strong spring is to prevent damage to the polyvinyl chloride coated on the metal frame of the culture cage by pressing, and to prevent the connecting string of the culture cage from being damaged. This is to prevent the culture basket from being damaged by winding the net.

[0009] At present, such a work can be performed because the work interval for withdrawing the cultured basket from the sea has been slightly shortened, and it has become less likely that crushed deposits are produced. The culture basket used in the present invention is based on the aforementioned round basket or square basket. If the culture basket has debris enough to be crushed, adjust the strength of the spring in advance, and unavoidably apply the spring pressing force only to such a thing. To do it. However, this may cause damage to the farming basket.

[0010] In the above-described washing device for a culture cage, a movable shaft rubber roller suspended by a spring is opposed to each of two fixed shaft rubber rollers arranged in parallel in the horizontal direction. A guide groove is provided on the side wall of the apparatus so that the rotating shaft of the movable shaft rubber roller can move up and down. The axial position of the movable shaft rubber roller fluctuates depending on the degree of overlap of the culture baskets during washing. The thickness of the culture baskets at the time of washing is about 3 to 5 cm for a round basket and about 2 to 3 cm for a square basket, so it is sufficient if the length of the guide groove is about 7 cm.

[0011] In the second invention, a wire mesh conveyor is brought close to each rubber roller on the aquaculture car transfer surface between the entrance of the culture car and the first rubber roller, and a loading auxiliary roller is placed on the conveyor. -In order to suppress the floating of aquaculture cages, a required number of wire mesh bridges are provided on other transfer surfaces in close proximity to each rubber roller. The loading support rollers are supported by springs, but they are not enough to damage the farming cage. The wire mesh conveyor should be close to the first rubber rollers so that the connecting cords and nets of the cultivation cage will not be entangled with the rubber rollers and damaged. -If a farming basket is inserted directly between the cages by hand, the connecting string and the mesh thread of the farming basket are likely to be caught in each rubber roller and easily damaged. It is also to omit. The driving sprocket of the wire mesh conveyor is directly connected to the driving sprocket of one fixed shaft rubber roller by a chain.

[0012] A wire mesh bridge installed in close proximity to each rubber roller on another transfer surface not only functions as a transfer bridge, but is conventionally used when a farming basket is transferred. In contrast to those with no transport assistance surface and those with perforated plates on the transport surface and a slightly larger gap between the rubber rollers in consideration of only the transport of the culture cage, the This is to prevent the net yarn from getting caught in the gap and stopping the operation or damaging the cultured cage.

[0013] A wire mesh such as stainless steel is used for the wire mesh conveyor and the wire mesh bridge in consideration of corrosion protection. High pressure water is easily passed through the wire mesh, and the pressure is not released by the reflected water, so that the effect of high pressure water cleaning can be sufficiently obtained. Conventional perforated plates reflect a lot of high-pressure water. In addition, the wire mesh is provided with a mesh (about 3 mm mesh) that allows the washing wastewater containing the attached matter to easily pass through. If transparent windows are provided on the side wall and lid of the equipment, the internal state can be monitored and operation management can be easily performed.

[0014] In addition to the above, a feeder and a receiver for aquaculture cages whose heights are adjusted to the transporting surface of the aquaculture cage before and after the entrance of the aquaculture cage by the washing device are provided, and a connection cord or net of the aquaculture cage is provided. It is advisable to use a flat plate so that the thread does not get caught, and to adjust the height to the position where the worker manually works.

In the washing apparatus, during the transportation of the culture car, high-pressure seawater that reciprocates in a range where the width of the culture car is sufficiently covered from above is sprayed onto the culture car at a position where there is no rubber roller. Seawater is suitable for mass use because it is easily available. As the farming basket moves slowly, the cleaning is covered by each nozzle. About 3 to 4 high-pressure seawater injection nozzles are sufficient, including immediately after the entrance to the culture cage. The high-pressure seawater injection nozzle branches off at a right angle to the high-pressure seawater pipe and a straight pipe slidably fitted at each end, and its base is directly connected to a gear motor via a connecting rod. The lever is connected to the eccentric part of the flywheel to form a lever crank mechanism. The injection pressure of high-pressure seawater is preferably about ²⁰ to 30 kg / cm ² . In case the high-pressure water injection nozzle is blocked by foreign matter in the seawater for cleaning, the response can be promptly made by making it visible through the plastic transparent window provided on the side wall and lid of the device. .

【Example】

 Hereinafter, the embodiment of the present invention will be described in more detail with reference to the equipment for preventing damage to the clam culture cage during washing. As shown in Fig. 1, the culture cage cleaning device having the equipment for preventing the damage of the culture cage is equipped with two fixed shaft rubber rollers 1 (the surface layer is 10 mm of rubber) arranged in parallel in the horizontal direction. A 65 kg "movable shaft rubber roller-3" (with a surface layer of 10 mm of rubber) suspended by a "spring 2" is placed on the opposite side, and the rotating shaft of the "movable shaft rubber roller-3" is moved up and down. A guide groove (not shown) is provided on the side wall of the device so as to be movable.

Also, the first rubber rollers are introduced from the entrance so that the culture cage is sequentially bitten and transported by the “movable shaft rubber roller-3” and the fixed shaft rubber roller-1, which are pressed by their own weights. Until 1,3, "wire mesh conveyor-4" and "carry-in auxiliary roller-5" are combined, and then each rubber roller-1,3 is put on the transfer surface to the exit of the culture cage. Two "wire mesh bridges 6" are set close to each other, and during the transfer of the culture car, three reciprocatingly reciprocatingly move the culture car from above in the width direction of the culture car without the rubber rollers 1,3. High-pressure seawater is jetted by the nozzle 7 of FIG. A drop 8 is provided for the washing wastewater that falls from the culture basket.

If the main dimensions in the washing device are shown, the feeding stand and the receiving stand of the culture basket are 700 mm in height, 1010 mm in width and 700 mm in length, and the bottom of the side wall of the washing device is 370 mm from the ground. The side wall has a width of 1010 mm, a length of 1200 mm, and a height of 850 mm. Each rubber roller-1, 3 is 910 mm long and 300 mm thick. High pressure seawater was used at an injection pressure of 28 kg / cm ² and 220 L / min. Based on the above, the washing amount of cultured scallop cultivation baskets is as follows. A single line is coated with polyvinyl chloride. A circular (60 cmφ) 10-stage (1 stage 20 cm) iron wire frame is made of nylon net and cylindrical with a bottom at each stage. 3 to 5 trains per minute, 1 train has the same coating on a square iron wire frame with 35 cm on a side, and the same kind of net is stretched in a cone shape. In the case of the cultivation basket, 2 to 4 per minute was possible, and in each case, no damage to the culture cage was observed.
