Description

Technology Field

[0001] The present invention relates to an automatic scattering method for shellfish (such as short-necked cockles, clams, surf clams, surf clams, true cockles, blood cockles, razor clams, true scallops, and freshwater clams) using water pressure. More specifically, the method comprises a step of receiving shellfish in a shellfish storage tank, a step of supplying seawater to a shellfish storage tank, and scattering shellfish by spraying water pressure onto the shellfish.

[0002] The method comprises the step of opening the hinged valve so that the shellfish contained in the shellfish storage tank fall to the water pressure spraying device (30) and are sprayed into the sea by water pressure.

[0004] To summarize the configuration, a system is provided that discharges shellfish contained in a shellfish storage tank to the bottom of the shellfish storage tank along with water, and then disperses the discharged shellfish by scattering them far away using water pressure. Background Technology

[0005] Conventional shellfish production methods were primitive harvesting methods centered on collecting from tidal flats or coastal waters. However, due to social changes and technological advancements in harvesting, the tidal flats and fishing grounds themselves have become degraded or spat have been depleted, making it impossible to harvest using conventional methods.

[0006] The shellfish farming industry is developing into a system where micro-scalds are cultured through seed farms until they reach a size capable of growing independently in mudflats or nearby fishing grounds, and then released into mudflats and other areas.

[0007] The process from fine spat to sprayable spat involves rearing them in a culture facility using phytoplankton as feed; however, the method of spraying at the seeding stage relies almost entirely on manual labor.

[0008] Although there are occasional proposals to promote fixed-distance spraying using mechanical axial fans, concretely applicable commercialization remains lacking.

[0010] Shellfish farming in Korea has been limited to a few species, such as oysters, ark shells, short-necked cockles, scallops, Manila clams, and surf clams, and furthermore, with the exception of oyster farming using the suspended culture method, most shellfish farming is carried out irregularly and unplannedly due to a shortage of natural spat, the lack of established mass production and farming techniques for artificial spat, and frequent mass mortality of farmed organisms. In addition, production volume is decreasing every year due to marine environmental pollution, the deterioration of fishing grounds and habitat reduction caused by land reclamation and landfilling, as well as indiscriminate overfishing.

[0012] Previously, cockle spat or juvenile spat were manually scattered from a ship onto a scattering area or mudflat using tools such as shovels. This scattering method had the problem that the spat were not evenly distributed but scattered unevenly. Korean registered patent No. 10-1666788 discloses an invention regarding a spat scattering device, but such an invention requires the consumption of electricity for supplying and controlling water pressure during spat scattering. Accordingly, the present invention is a cockle spat scattering device capable of increasing scattering efficiency and reducing power consumption.

[0014] Previously, cockle spat or juvenile spat were manually scattered from a ship onto the scattering area or mudflats by workers using shovels and other tools. This scattering method had the problem that the spat were not evenly distributed and were scattered unevenly.

[0016] In the past, the method of scattering spat into the bottom of the aquaculture farm involved the worker scattering the spat manually on the boat using a shovel or similar tool.

[0017] However, the conventional method of scattering seed shellfish had the following problems.

[0018] If spat is scattered manually, the spat is not evenly distributed and becomes concentrated, causing problems that hinder future growth.

[0020] Registration number 10-1666788 is provided to resolve this.

[0021] The composition and examples are as follows.

[0022] When the slide (22) is opened at identification number

[0037] , the shellfish descends by its own weight and moves along the guide section (32) of the dispersion section (30), and after settling on the wing section (38), moves into the sea along the extension section (34) by the nozzle (36).

[0023] At this time, the direction in which the seed is dispersed can be controlled using the control unit (50).

[0024] The hopper section (10) cannot go down below the hopper section because it is pressed together by the self-gravity of the seed shellfish.

[0025] Due to this, seed scattering is impossible.

[0026] To add further explanation, in the case of the process of discharging downwards through the discharge port of the hopper section (10) (corresponding to the opening / closing valve (50) in the present invention), a problem arises in which the weight of the seed shellfish is increased.

[0027] As a result, it is even more difficult to expel shellfish.

[0028] Also, there is no way to resolve the situation where the spat may be stacked in the dispersion section (30) and the three divided sections and cannot move forward. The problem to be solved

[0029] Taking into account the aforementioned conventional problems, the present invention relates to an automatic shellfish scattering method using water pressure, and more specifically, comprises a shellfish receiving step in a shellfish storage tank, a seawater supply step to the shellfish storage tank, and scattering shellfish by spraying water pressure onto the shellfish.

[0030] The method comprises the step of opening the hinged valve so that the shellfish contained in the shellfish storage tank fall into the water pressure spraying device (30) and are sprayed into the sea by water pressure.

[0032] The above-mentioned tasks are further revealed in the specific details. means of solving the problem

[0036] A step of spraying seawater using the pressure spray hose (70) to spray seawater from the bottom of the pressure spray device (30) toward the front upper air through the pressure spray hose (70); S3

[0037] After the step of spraying seawater, the opening valve (50) is opened so that when the shellfish (200) contained in the shellfish storage tank (10) reaches the water pressure spraying device (30), the shellfish are sprayed into the sea by water pressure; this is performed in step S4. Effects of the invention

[0039] 1. The present invention provides a system that allows shellfish contained in a shellfish storage tank to flow down to the bottom of the shellfish storage tank along with water, and then disperses the flowing shellfish by scattering them far away using water pressure, thereby making the shellfish scattering operation convenient and fast.

[0040] 2. Since the hydraulic jet device vibrates, shellfish do not accumulate and stagnate.

[0043] To explain the scattering method, a shellfish receiving step in the shellfish storage tank (10) in which shellfish (200) are received in the shellfish storage tank (10) using equipment (crane, etc.); S1

[0044] After the shellfish receiving step (S1) in the shellfish storage tank (10), a seawater supply step to the shellfish storage tank (10) using a motor pump to supply seawater; S2

[0045] After the seawater supply step (S2) to the above shellfish storage tank

[0046] A step of spraying seawater using the pressure spray hose (70) to spray seawater from the bottom of the pressure spray device (30) toward the front upper air through the pressure spray hose (70); S3

[0047] After the step of spraying seawater, the opening valve (50) is opened so that when the shellfish (200) contained in the shellfish storage tank (10) reaches the water pressure spraying device (30), the shellfish are sprayed into the sea by water pressure; this is performed in step S4.

[0049] As mentioned above, the water pressure is sprayed upward and forward from beneath the shellfish passing through the water pressure sprayer.

[0051] The configuration is re-examined with reference to the attached drawings, and the corresponding embodiments are described as follows.

[0053] A shellfish storage tank (10) fixed to a vessel (100) by a temporary attachment / detachment method by means of attachment / detachment (a), a guide frame (20) that guides shellfish (200) falling to the bottom of the shellfish storage tank (10) by a certain distance or more, and a water pressure spraying device (30) that sprays shellfish falling to the end of the guide frame (20) forward by water pressure.

[0055] The above shellfish storage tank (10) is connected to the shellfish storage tank (10) by a water hose (40) that continuously introduces external water, and a shut-off valve (50) is installed at the bottom of the shellfish storage tank (10) to seal the shellfish (200) or to allow the shellfish to fall outside the bottom of the shellfish storage tank (10).

[0057] A pressure hose (60) with water pressure is connected to the bottom of the shellfish storage tank (10) so that the shellfish are continuously scattered by the water pressure, and when the opening valve (50) is opened, the shellfish fall to the outside of the bottom of the shellfish storage tank (10), pass through the guide frame (20) and the pressure spray device (30), and head toward the sea.

[0058] The shellfish storage tank (10) has a hopper-shaped bottom, so there are cases where the shellfish cannot fall down even if the opening valve (50) is opened due to being crushed by the weight of the shellfish.

[0060] Herein is an example) However, when water pressure is injected from below to the upper side inside the shellfish storage tank (10) at high pressure, the shellfish that are pressed together are separated from each other and are not pressed, so when the opening valve (50) is opened, the shellfish (200) fall to the outside.

[0062] When high pressure is sprayed from the bottom to the top of the shellfish storage tank (10) by means of a nozzle (not shown) connected to the end of the above-mentioned hydraulic hose (60), the shellfish are excavated by the hydraulic pressure.

[0063] This water pressure is achieved through a motor pump (not shown) connected to a water pressure hose (60).

[0064] The motor pump of the present invention pumps seawater from the sea.

[0066] In the present invention, the pressure of the water pressure is increased or decreased, and in the process of decreasing the pressure, the shellfish falls through the open / closed valve (50) by its own weight and into the guide frame (20).

[0068] It is worth noting here that high water pressure continuously pushes shellfish upwards.

[0069] When floating (raising), the floating can be sustained, which hinders the shellfish from falling toward the opening / closing valve (50).

[0070] To further elaborate on the technology, shellfish are scattered into the sea as the vessel moves; the scattering volume is controlled by repeatedly dropping and blocking the shellfish according to the vessel's speed, thereby regulating the amount of shellfish falling.

[0072] In this invention, the shellfish are dropped while repeatedly being stirred up by water pressure.

[0074] The above guide frame (20) is installed so that one side receives the shellfish (200) falling to the bottom of the opening / closing valve (50) and moves along the slope to the other side while falling, and the above pressure spray device (30) is formed with a mesh (31) through which water pressure passes on the bottom surface of the above pressure spray device (30) so that the falling shellfish is received from the guide frame (20) and sprayed into the sea by water pressure, and the pressure spray hose (70) is equipped with a discharge port (71) on the bottom surface of the above mesh (31) so that as the shellfish passes through the above mesh (31), it is scattered into the air above the shellfish (200) by the water pressure sprayed through the discharge port (71) and sprayed into the sea.

[0076] As described above, when water pressure is sprayed from the bottom of the net (31) toward the upper front, the shellfish are scattered toward the upper front and head toward the sea.

[0079] A duct (not shown) that discharges strong wind from a blower (not shown) is installed at the bottom of the above net (31) to float the shellfish through the strong wind as the shellfish pass through the guide frame (20) and the net (31).

[0080] By floating them in this way, the aforementioned shellfish can be dispersed further along with the water pressure.

[0082] When the rear of the hydraulic spray device (30) is connected to the front end of the guide frame (20) by a hinge (32), the front of the angle adjustment lever is connected to the rear of the hydraulic spray device (30), and the rear of the angle adjustment lever (33) becomes a handle (34), and the handle (34) is moved up and down

[0083] The front of the above-mentioned hydraulic injection device (30) is configured to be adjustable in an angle up and down around the above-mentioned hinge (32).

[0084] When the angle is adjusted in this way, the operator can hold the handle and send shellfish to close and far distances from the vessel at various angles.

[0086] The rear end of the hydraulic spray device (30) is connected to the front end of the guide frame (20) by a hinge (32), and the front of the angle adjustment lever (33) is connected to the rear of the hydraulic spray device (30). When the rear of the angle adjustment lever (33) maintains gravity by a heavy object (35), the front of the hydraulic spray device (30) is facing upward with the hinge (32) acting as the central axis. When the opening / closing valve (corresponding to a sliding door) of the shellfish storage tank (10) is artificially opened by a worker, the shellfish (200) passes quickly (the speed of descent varies depending on the angle of inclination) along the guide frame (20) which is inclined downward and strikes the front of the hydraulic spray device (30) while being sprayed into the sea. During this process, the impact intensity varies depending on the weight of the shellfish (the shellfish do not fall from the shellfish storage tank in a fixed amount but fall in a jumbled, varied amount). At this time, the The front of the hydraulic spray device is at a predetermined angle centered on the hinge (32).

[0087] The configuration is such that in a repeated process of rotating and then returning to the original position by a heavy object, shellfish pass in front of the above-mentioned hydraulic spray device (30) and are irregularly sprayed into the sea.

[0089] By spraying in such irregular directions, it can be sprayed more evenly over the sea area being treated.

[0091] A plurality of partitions (36) are arranged at regular intervals along the width direction of the hydraulic injection device (30) so that shellfish moving forward in the plane of the hydraulic injection device are dispersed and moved.

[0093] In order to move the stacked shellfish forward when the shellfish are stacked at the rear of the partitions (36) as they pass between the partitions (36), a shellfish moving means (80) is installed at the rear of the partitions (36). The shellfish moving means (80) is composed of a brush (81) that rotates by power, a rotor (82) that rotates the brush, and a motor (not shown) that is connected to the rotor (82) by a drive shaft to rotate it.

[0095] In an example, when the brush (81) is rotated by a motor (not shown), it pushes the shellfish forward during the rotation process. If the shellfish is blocked by a partition and cannot move forward during this process, it moves with the help of the rotating brush.

[0096] By configuring it in this way, even if shellfish are stacked, the stacking can be resolved.

[0098] When the weight of shellfish is excessive on the above-mentioned hydraulic spray device (30), the front part rotates around the hinge (32) and descends at a predetermined angle. As a result, even if shellfish are stacked, the front part descends, so the shellfish can be easily scattered into the sea.

[0100] The above hydraulic spray device (30) has a rotor (80) at the rear upper end that rotates by a motor (not shown), and the rotor (80) has a brush (81) formed on its circumference, with one side of the brush (81) connected to the rotor (80) by a hinge shaft (83), and the other side of the brush (81) rotates at a predetermined angle only in the direction of movement of the shellfish (200) as it is pushed by the shellfish (200) falling from the guide frame around the hinge shaft (83).

[0101] When the above rotor (82) is rotated by the motor, the brush (81) rotates, and when continuously falling shellfish accumulate at the rear of the above hydraulic spray device (30), the brush moves forward by the rotation.

[0102] This resolves the stacking issue. Explanation of the symbols
