The present invention provides a hyeongnet fishing gear capable of stably moving in seabed soil and easily collecting shellfish.

Description

Apparatus for picking up shellfish}

The present invention relates to an apparatus, and more particularly, to a fishing gear for collecting shellfish inhabiting the seabed.

Hyeongnet fishing gear is known as an equipment for collecting shellfish inhabiting the seabed. The hyeongnet fishing gear collects shellfish inhabiting the surface by scratching the surface of the sea floor with a rake. In some cases, the rake is caught on obstacles such as stones or rocks located on the surface of the sea floor. If the size of the obstacle caught by the rake is small and the obstacle is easily separated from the surface, the fishing gear can continue to be towed without a big problem, but when the obstacle is a heavy object such as a rock, the fishing gear of the fishing gear becomes very difficult.

If the fishing gear is caught in an obstacle and it is difficult to move, the fishing gear must be retracted and then moved so that the fishing gear bypass the obstacle.This process takes a lot of time and can seriously damage fishing behavior. . In addition, if the fishing gear is seriously caught in an obstacle, a problem of damage to the fishing gear may occur, and in some cases, a situation in which the fishing gear is left alone on the sea floor may result.

1 is a schematic perspective view of a hyeongnet fishing gear 100 according to an embodiment of the present invention.

Referring to FIG. 1, the hyeongnet fishing gear 100 includes a first sliding member 110, a second sliding member 120, a connecting member 125, a rotating shaft 130, a filter mesh frame 135, and a rake 140. , A rotation control unit 150, a first mesh 160, a filter mesh 170, a first connector 180a, and a second connector 180b may be provided.

The first sliding member 110 and the second sliding member 120 may extend in the front and rear direction of the hyeongnet fishing gear 100 and may be disposed to be spaced apart from each other. A direction in which the first slide member 110 and the second slide member 120 are spaced apart may be a direction perpendicular to the longitudinal direction of the first slide member 110 and the second slide member 120.

The first sliding member 110 and the second sliding member 120 may include a contact plate in contact with the sea floor and a vertical plate extending from the contact plate. The contact plate is in contact with the sea floor when the hyeongnet fishing gear 100 comes into contact with the seabed, so that the contact area between the hyeongnet fishing gear 100 and the seabed may be increased. When the hyeongnet fishing gear 100 is driven, the contact plate may maintain contact with the sea floor.

The first slide member 110 may include a first guide groove 111, and the second slide member 120 may include a second guide groove 121. The first guide groove 111 may be formed to penetrate the vertical plate of the first sliding member 110, and the second guide groove 121 may be formed to penetrate the vertical plate of the second sliding member 120. The first guide groove 111 and the second guide groove 121 may be disposed to face each other.

The first guide groove 111 and the second guide groove 121 may be long hole holes extending along the length direction of the first slide member 110 and the second slide member 120. The rotation adjustment unit 150 may be coupled to the first guide groove 111 and the second guide groove 121. That is, one end of the rotation control unit 150 may pass through the first guide groove 111, and the other end of the rotation control unit 150 may pass through the second guide groove 121. The first guide groove 111 and the second guide groove 121 may guide the rotation adjustment unit 150 to rotate in the j-axis direction. In addition, the rotation control unit 150 may perform linear motion along the length direction of the long hole of the first guide groove 111 and the second guide groove 121.

The connecting member 125 may be installed at the rear ends of the first sliding member 110 and the second sliding member 120. The connecting member 125 may fix the first mesh 160 to the end. In addition, the connecting member 125 may support the mesh frame 135 and the filter mesh 170 disposed thereon in one direction.

The connection member 125 may include, for example, a load support 126, a connection frame 127, and a joint frame 128.

The load support 126 may connect the first sliding member 110 and the second sliding member 120. The load support 126 may have a bar shape as an example of connecting the first sliding member 110 and the second sliding member 120. The bar-shaped load support 126 may be at least one or more.

The strainer frame 135 and the strainer 170 may be placed on the load support 126. That is, the filter mesh frame 135 and the filter mesh 170 may be placed in a space formed by the load support 126, the first sliding member 110, and the second sliding member 120, and by the load support 126 Can be supported.

The present invention is not limited thereto, and the load support 126 may have various shapes capable of supporting the first slide member 110 and the second slide member 120.

The connection frame 127 may extend from the load support 126 to the rear end from the first slide member 110 and the second slide member 120. As an example, the connecting frame 127 has one end extending from the load support 126 toward the lower end of the first sliding member 110, and after extending to a predetermined length, the first sliding member 110 and the second sliding member It extends in a direction spaced apart from 120 and extends in a direction toward the second sliding member 120 so that the other end thereof may be connected to the load support 126. That is, the connection frame 127 may have a shape in which both ends of the load support 126 extend toward the rear ends of the first slide member 110 and the second slide member 120 at different positions.

The connecting frame 127 includes a first portion 127a and a second slide member 120 extending from a portion of the load support 126 adjacent to the first slide member 110 in the rear end direction of the first slide member 110. A second portion 127b extending in the rear end direction of the second sliding member 120 in a portion of the load support 126 adjacent to, and spaced apart between the first sliding member 110 and the second sliding member 120 A third portion 127c extending in the direction and connecting the first portion 127a and the second portion 127b may be formed. The first portion 127a and the second portion 127b may be formed such that the distance between both ends thereof becomes narrower toward the third portion 127c.

The joint frame 128 may extend from the connection frame 127 to fix the first mesh 160. As an example, the joint frame 128 is a third part 127c in a direction crossing the plane formed by the first part 127a, the second part 127b, and the third part 127c in the third part 127c. ) Can be extended. As an example, the joint frame 128 may extend vertically on the plane. The joint frame 128 may have one end extending from one part of the third part 127c and the other end connected to another part of the third part 127c.

The first mesh 160 may be fixed to the joint frame 128. The first mesh 160 may be fixed along the joint frame 128 and may also be fixed to the third part 127c. Accordingly, the joint frame 128 and the third portion 127c may become the entrances of the first mesh 160. Fish and shellfish on the seabed introduced into the sieve 170 may be introduced into the first net 160 through an inlet formed by the joint frame 128 and the third portion 127c. Sand or mud (m) of the seabed introduced into the sieve 170 may be discharged to the outside through the bottom and side surfaces of the sieve.

The first mesh 160 and the filter mesh 170 may be connected or separated through the joint frame 128. When the filter mesh frame 135 is supported by the load support 126, the first mesh 160 and the filter mesh 170 communicate with each other, so that the shellfish S may flow into the first mesh 160. However, as shown in FIG. 5, when the filter mesh frame 135 rotates and rotates upward, the first mesh 160 and the filter mesh 170 are separated so that the shellfish S does not flow into the first mesh 160.

The weight 195 may be installed at the rear and bottom of the filter mesh 170. The weight 195 has a predetermined mass. The weight 195 receives a force in a downward direction by gravity. When the resistance received by the rake while the hyeongnet gear 100 is moving is less than the gravity of the weight 195, the rake is not pushed back due to the weight of the weight 195, and accordingly, the rotating shaft 130 does not rotate and the filter mesh Since the shell 170 and the first mesh 160 are connected to each other, the shellfish S introduced into the filter mesh 170 may flow into the first mesh 160. That is, normal operation is possible.

However, when the resistance received by the rake as the hyeongnet gear 100 moves is greater than the gravity of the weight 195, the rake 140 is pushed back due to the resistance received by the rake 140 and the rotation shaft 130 rotates. And the filtering net 170 is also rotated. Accordingly, the filtering net 170 and the first net 160 may be separated.

That is, when the hyeongnet fishing gear 100 is pulled, the rake 140 generates resistance due to the geology, so a weight 195 applied in the opposite direction of the resistance is required, and the most in the traction frame 145 Weights 195 can be installed at the rear and lower ends of the filter mesh 170 at a distant location.

The rotation shaft 130 may connect the first sliding member 110 and the second sliding member 120. The rotation shaft 130 may rotate about an i-axis, which is the width direction of the hyeongnet fishing gear 100, about a central axis. The rotation shaft 130 may be connected to the filter mesh frame 135. Therefore, as the rotation shaft 130 rotates, the filter mesh frame 135 also rotates. This will be described later.

A plurality of rakes 140 may be fixed to the rotating shaft 130 so as to face downwards of the hyeongnet fishing gear 100. When a plurality of rakes 140 collide with an obstacle R of the seabed and a resistance force is generated in the rake 140 in the direction opposite to the moving direction of the hyeongnet fishing gear 100, the rake 140 is pushed back, and the rake 140 And the fixed rotation shaft 130 is rotated. Since the rotation shaft 130 is connected to the filter mesh frame 135, when the rotation shaft 130 rotates, the filter mesh frame 135 may also rotate upwardly with respect to the i-axis.

The filtering net frame 135 may fix the filtering net 170. The filter net 170 may surround the filter net frame 135 so that one side and the other side opposite to the one side in the traveling direction of the hyeongnet fishing gear 100 are opened. The other side of the filter mesh frame 135 may correspond to the joint frame 128 which is an inlet of the first mesh 160. One side of the filter mesh frame 135 is an inlet and shellfish flows in, and the other side of the filter mesh frame 135 is an outlet, and shellfish and the like may flow out. Shellfish, etc. that flow out to the other side of the filter mesh frame 135 may flow into the first mesh 160.

The filter net frame 135 may include an inlet frame 136, a filter net frame support piece 137, a mounting frame 138, and an outlet frame 139 as an example.

The entrance frame 136 forms the entrance of the filter mesh frame 135. The entrance frame 136 is located at the front end of the first sliding member 110 and the second sliding member 120 and may be opened in the traveling direction of the hyeongnet fishing gear 100. Since the inlet frame 136 is open, shellfish (S) can be introduced from the rake 140.

The inlet frame 136 may be fixed to the rotating shaft 130. That is, one end of the inlet frame 136 may be fixed to one part of the rotation shaft 130 and the other end of the inlet frame 136 may be fixed to the other part of the rotation shaft 130. The inlet frame 136 may rotate together as the rotation shaft 130 rotates.

The outlet frame 139 may be disposed so as to face the inlet frame 136 and face the first mesh 160. The outlet frame 139 may form an outlet of the filter mesh frame 135. The exit frame 139 may be located at a front end of the first slide member 110 and the second slide member 120. The exit frame 139 may be opened toward the first mesh 160. The shellfish (S) introduced through the inlet frame 136 may pass through the filter mesh 170 and flow out to the outlet frame 139 to flow back into the first mesh 160.

The filter mesh frame support piece 137 may be disposed between the inlet frame 136 and the outlet frame 139. That is, the filter mesh frame support piece 137 may be in the shape of a bar extending from the inlet frame 136 to the outlet frame 139. The filter mesh frame support piece 137 may have one end fixed to the rotating shaft 130 and the other end fixed to the outlet frame 139. At least one of the filter mesh frame support pieces 137 may be disposed between the rotating shaft 130 and the outlet frame 139. The filter mesh frame support piece 137 may define a floor area inside the filter mesh 170.

The mounting frame 138 is installed vertically from the lower portion of the filter mesh frame 135 to define an inner space of the filter mesh 170. The mounting frame 138 may extend from the gait net frame support piece 137 in a direction perpendicular to a plane formed by the plurality of gait net frame support pieces 137.

The elastic member 190 is disposed between the first mesh 160 and the filter mesh 170, and an elastic force may act in the first mesh 160 and the filter mesh 170. The elastic member 190 is connected to each of the first mesh 160 and the filter mesh 170, and performs a function of applying an elastic force to the rotated filter mesh 170 to return to the position before rotation. The elastic member 190 may rotate the filter mesh 170 to its original position by acting an elastic force in a direction opposite to the direction in which the filter mesh 170 is rotated.

In more detail, the elastic member 190 may have one end connected to the joint frame 128 fixing the first mesh 160, and the other end of the elastic member 190 may be connected to the filter mesh frame 135 fixing the filter mesh 170. . As shown in Fig. 5, when the filter mesh frame 135 is rotated, the elastic member 190 connecting the joint frame 128 and the filter mesh frame 135 is increased. The stretched elastic member 190 may be rotated in a direction opposite to the direction in which the filter mesh frame 135 is rotated by an elastic force acting in a direction opposite to the stretched direction. Accordingly, the filter mesh frame 135 may return to the position before rotation as shown in FIG. 4A.

As described above, the rotating filter mesh frame 135 may be rotated in a direction opposite to the rotated direction by the weight of the weight 195 installed in the filter mesh 170, but the rake 140 is deeply embedded in the seabed. In a special situation, only the weight 195 may not be able to return the rotated filter net frame 135 to its original position. The elastic member 190 applies an elastic force to the filter screen frame 135 rotated as described above, so that the rotated filter screen frame 135 may more easily return to its position.

FIG. 2A is an enlarged view of area A of FIG. 1.

Referring to FIG. 2A, a plurality of rakes 140 may be provided, and may be installed side by side along the rotation shaft 130. One end of the rake 140 is fixed to the rotary shaft 130 and extends downward of the hyeongnet fishing gear 100, and the other end of the rake 140 may be bent toward the front of the hyeongnet gear 100. The direction in which the other end of the rake 140 is bent may be the same direction as the moving direction of the hyeongnet fishing gear 100. Accordingly, as the hyeongnet fishing gear 100 proceeds, the rake 140 may contact the seabed to scratch the shellfish S in the seabed.

The rake 140 may include, for example, a base 141, a blade 142, a reinforcing piece 143, and a court piece 144.

The base 141 may extend in one direction and may be formed in a plate shape. One end of the base 141 may be easily fixed to and detach from the rotation shaft 130. As an example, the base 141 and the rotating shaft 130 may be fixed to each other in a manner in which a bolt and a nut are fastened.

The other end of the base 141 may extend to the blade 142. The blade 142 may be bent from the base 141 toward the front end of the hyeongnet gear 100. That is, the blade 142 is bent and extended in the traction direction of the gear at the other end of the base 141.

As shown in FIG. 2A, the blade 142 has a shape like a skate blade, but is not limited thereto and may be modified in various forms.

The tip of the blade 142 may be sharply formed to scratch the sea floor.

The reinforcing piece 143 may be disposed below the blade 142. The reinforcing piece 143 may be disposed beyond the end of the blade 142. That is, the reinforcing piece 143 may protrude toward the hyungnet gear from one end of the blade 142 facing the direction of the hyeongnet gear.

The reinforcing piece 143 may be a square bar or a round bar. The width or diameter of the reinforcing piece 143 may be larger than the width of the blade 142. When the reinforcing piece 143 is disposed on the lower surface of the blade 142, a point where the upper surface of the reinforcing piece 143 and the side surface of the blade 142 meet each other may be formed, and by welding the points, the reinforcing piece (143) can be coupled to the blade (142). As an example, the edge of the lower end of the blade 142 in contact with the reinforcing piece 143 may be chamfered. It can be welded to cover the chamfer. Due to the chamfer, the welding area is increased, so that the bonding force between the reinforcing piece 143 and the blade 142 may be improved.

The reinforcing piece 143 may be heat treated. Since the reinforcement piece 143 penetrates the sea floor, a lot of wear and tear may occur. The reinforcing piece 143 may increase strength and increase durability through heat treatment. If the abrasion of the reinforcing piece 143 is severe, it can be removed and replaced. As described above, the reinforcing piece 143 is in the form of a square bar or a round bar, and since it is coupled to the lower end of the blade 142 through welding without changing its shape for bonding with the blade 142, it is easy to repair or replace.

In addition, when the reinforcing piece 143 receives strong resistance from the ground, the stiffness may be reinforced so that the blade 142 does not bend left and right.

The yard piece 144 may be formed to protrude from the upper end of the blade 142 to both sides. The yard piece 144 may be formed to be slightly inclined at the front side of the blade 142 low and the rear side high. When the hyeongnet fishing gear 100 is towed, the yard piece 144 can play a role of raising the geology (sand, sand, gravel, etc.) spaced from the front of the blade 142 upward, and the geology (sand, sand, gravel, etc.) Etc.) and shellfish can be effectively separated and collected.

Each groove may be formed at the lower and upper ends of the blade 142, and a reinforcing piece 143 may be inserted at the lower end and a yard piece 144 may be inserted at the upper end. Thereafter, the contact portions of the reinforcing piece 143 and the court piece 144 may be welded to be fixed to the blade 142. The plurality of rakes 140 may be fixed to be spaced apart from each other by a predetermined distance by the traction frame 145 and the first fixing piece 146.

The traction frame 145 extends along the rotation shaft 130 and may be installed at a portion connected to the base 141 and the blade 142 at the end. The traction frame 145 may have a base 141 inserted therein to support a plurality of rakes 140. The front end of the traction frame 145 may have a slit-shaped groove formed toward the rear end.

The base 141 may be inserted into the slit and fixed to the traction frame 145 by welding or the like, and a pin installed on the base 141 may support the vertical movement of the traction frame 145. Since the base 141 is inserted from the front end of the traction frame 145 toward the rear end and the rear end is blocked, the base 141 can be firmly fixed to the traction frame 145. In addition, the traction frame 145 may distribute it to other rakes even if excessive impact and resistance occurs on a specific rake.

The first fixing piece 146 may be installed in a horizontal direction between the blades 142 of the plurality of rakes 140.

The first fixing piece 146 is installed between the reinforcing piece 143 of the blade 142 and the yard piece 144 to maintain the spacing of the blade 142. The first fixing piece 146 may prevent the blade 142 from moving left and right due to resistance to excessive impact.

In the state of harvesting shellfish (S), the hyeongnet fishing gear 100 moves while the rake 140 scratches the bottom of the sea, and the shellfish S passes through the sieve 170 and is stored in the first net 160. . Shellfish (S) is easily separated from the geology of the ground surface by the yard piece 144, so it can be collected separately from the sea floor.

2B is a perspective view showing a modified example of FIG. 2A.

The modified example shown in FIG. 2B differs from FIG. 2A in that there is no yard piece 144. That is, in the modified example shown in FIG. 2B, there is no yard piece 144 at the top of the blade 142. Instead, a wire 142b passing through the blade 142 may be provided. The wire 142b may be disposed to pass through a through hole 142a penetrating from one side of the blade 142 to the other side.

The wire 142b disposed between the blades 142 may contribute to separating the shellfish S embedded in the seabed. In detail, when the rake 140 moves while scratching the sea floor in an area where the sea floor is made of a soft pen, the friction or resistance by the pen is small, and as shown in FIG. 2A, the court piece 144 at the top of the blade 142 Rather, it can damage thin shells such as scallops. In an area where friction or resistance is small, a rake 140 having a wire 142b as shown in FIG. 2B can minimize damage to shellfish with a thin shell.

2C is a perspective view showing another modified example of FIG. 2A.

The modified example shown in FIG. 2C is different from FIG. 2A in that it further includes a spray nozzle unit 240. The spray nozzle unit 240 may inject a fluid to the rake 140 to reduce the resistance of the rake 140. The spray nozzle unit 240 may include a spray nozzle 241, a connection pipe 242, and a pump (not shown). The spray nozzle 241 may be installed on one side of the rake 140. The injection nozzle 241 may discharge a high-pressure fluid supplied from a pump (not shown). Since the spray nozzle 241 sprays the fluid toward the working direction of the rake 140, it is possible to reduce the resistance of the fishing gear.

The connection pipe 242 may connect a pump (not shown) and the spray nozzle 241 to supply a high-pressure fluid to the spray nozzle 241. A pump (not shown) may be installed at the end of the hyeongnet fishing gear to pressurize the introduced fluid (seawater). A pump (not shown) may be installed on one side of the strainer 170. The pump (not shown) is fixed to the filter screen frame 135 and can rotate together when the filter screen 170 is rotated.

Referring back to Figure 1, the rotation adjustment unit 150 is installed to be inserted into the first guide groove 111 of the first sliding member 110 and the second guide groove 121 of the second sliding member 120. I can. In other words, the rotation adjustment unit 150 is disposed between the first sliding member 110 and the second sliding member 120, and one end of the rotation adjustment unit 150 passes through the first guide groove 111, The other end of the rotation adjustment unit 150 may pass through the second guide groove 121.

The rotation control unit 150 may include a rotation bar 151 and a supporter 152 as an example.

The rotation bar 151 may be connected to the traction frame 145 by a first rope 181. A second rope 182 connected to the first connector 180a may be fixed to the rotation bar 151. Tension is applied to the first rope 181 and the second rope 182 due to the rotation of the rotation bar 151, and thus the rotation of the rake 140 may be started. This will be described in detail below.

The supporters 152 may be installed at both ends of the rotating bar 151. That is, one end of the supporter 152 may be connected to one end of the rotating bar 151 and the other end of the supporter 152 may pass through the first guide groove 111. Another supporter 152 may have one end connected to the other end of the pivoting bar 151, and the other end may penetrate the second guide groove 121.

The supporter 152 may linearly move along the first guide groove 111 and the second guide groove 121. In addition, the supporter 152 may rotate about a j-axis connected to the first guide groove 111 and the second guide groove 121.

The reinforcing frame 155 is installed between the first sliding member 110 and the second sliding member 120 to maintain a constant horizontal gap between the first sliding member 110 and the second sliding member 120 By doing, it is possible to prevent the deformation and damage of the hyeongnet fishing gear 100.

In order to increase the amount of operation by the hyeongnet fishing gear 100, the width of the fishing gear must be manufactured in a large size. However, as the size increases, the resistance force generated at the seabed also increases, so that the hyeongnet fishing gear 100 may be easily deformed or damaged. In particular, the rotating shaft 130 is relatively vulnerable to bending because it has a longer length compared to its cross-sectional area. In order to reinforce this, an inlet frame 136 may be installed.

3 is a plan view showing the mesh of FIG. 1.

1 and 3, the first mesh 160 may be fixed to the joint frame 128. The introduced shellfish S may be stored in the first mesh 160.

The filter mesh 170 may be installed on the filter mesh frame 135. The filter net 170 has the front entrance frame 136 and the rear exit frame 139 open, and the shellfish S collected from the rake 140 passes through the filter net 170 to the first net 160 Can be moved.

Sand, mud (m), shellfish (S), and the like are introduced into the filter net 170 from the rake 140 together. Among them, sand, mud, or small-sized shellfish, etc. may have a large mesh so that they are discharged out of the sieve 170.

The inlet end (F1) of the filter mesh 170 may be formed to have a wider open area than the outlet end (F2). Since the outlet end (F2) is formed with a narrow area, sand or mud (m) introduced into the sieve 170 can be easily discharged to the bottom and side of the sieve.

Hereinafter, the operation of the hyeongnet gear 100 according to an embodiment of the present invention will be described.

4A and 5 are cross-sectional views schematically showing an operating state of the hyeongnet fishing gear 100 of FIG. 1. In detail, FIGS. 4A and 5 are cross-sectional views schematically showing an operating state when the fishing gear 100 of FIG. 1 is caught on a submarine fixture.

4A, the hyeongnet fishing gear 100 moves along the seabed. Since the end of the rake 140 moves while scratching the sea floor, sand, mud (m), and shellfish (S) of the sea floor can be effectively separated from the sea floor by the role of the upper end of the blade 142 or the yard piece 144. have. The first rope 181 connects the rake 140 and the rotation control unit 150, the second rope 182 connects the rotation control unit 150 and the first connector 180a, and the third rope ( 183 may connect the fishing boat and the first connector 180. That is, the fishing boat that pulls the fishing gear 100 may be connected by the first connector 180 and the third rope 183 connected to the second rope 182. As the fishing boat moves, the third rope 183, the second rope 182, and the first rope 181 may be held taut due to tension. Accordingly, the rake 140 can maintain a constant position and maintain a force capable of scratching the seabed.

Sand, mud (m), shellfish (S), etc. in the seabed pass through the rake 140 and move to the sieve 170. Sand, mud, and small-sized shellfish from the sieve 170 are discharged to the outside again, and the shellfish S having an appropriate size may be moved to the first mesh 160 and stored.

Referring to FIG. 5, the movement of the hyeongnet fishing gear 100 is obstructed by an obstacle R on the seabed. When the size of the obstacle is small, the pawl 140 may move away from the obstacle R while rotating at a predetermined angle. However, when the size of the obstacle R is large and heavy, if the hyeongnet gear 100 is forcefully moved, it may be damaged.

According to an embodiment of the present invention, when the hyeongnet fishing gear 100 meets the obstacle R fixed to the seabed, the rake 140 rotates by the rotation control unit 150 and the rotation shaft 130 to cause the obstacle R Can escape.

In detail, even if the rake 140 collides with the obstacle R and is fixed, the first sliding member 110 and the second sliding member 120 of the hyeongnet fishing gear 100 continue to advance by the traction force of the fishing boat. The rake 140 is caught by the obstacle R and pushed back, and the rotation control unit 150 moves to the rear end of the guide groove by the first rope 181 connected to the rake 140 while simultaneously rotating about the j-axis. do. Thus, the rotation control unit 150 and the second rope 182 between the first connector (180a) and the tension is connected, and the first rope 181 between the rotation control unit 150 and the rake 140 is also tensioned It stays taut.

In addition, as the rake 140 is pushed back, the rotating shaft 130 rotates so that the filter mesh 170 may rotate upward. That is, in the hyeongnet fishing gear 100, the rake 140 rotates about the rotation shaft 130 due to the impact of the obstacle R.

Specifically, when in contact with the rake 140 and the obstacle R, the rake 140 is separated from the seabed by the traction force of the fishing boat. Since the resistance transmitted from the obstacle R causes the rotation control unit 150 and the rake 140 to move and rotate backward, the filter mesh frame 135 and the filter mesh 170 rotate upward. Thereafter, the entrance frame 136 stops rotating while contacting the reinforcing frame 155 or a separate device.

After passing through the obstacle, the filter net 170 and the pitchfork 140 rotate in opposite directions due to the traction of the fishing boat and return to the normal state as shown in FIG. 4, so that the operation can be resumed.

However, as described above, when the rake 140 is deeply embedded in the sea floor, the filter mesh 170 and the rake 140 may easily rotate in opposite directions and may not return to a normal state. As described above, according to the present invention, the filter mesh 170 rotated by the elastic member 190 disposed between the first mesh 160 and the filter mesh 170 can be rotated in the opposite direction.

Referring to FIG. 4B, the elastic member 190 may connect the connection member 125 and the outlet frame 139. The connecting member 125 is a joint spaced apart from the first point P1 in the area where the connecting frame 127 and the joint frame 128 are in contact with each other in a direction crossing the connecting frame 127 at the first point P1 It may have a second point P2 on the frame 128. In addition, the exit frame 139 intersects the walking net frame support piece 137 at the third point (P3) in the area where the filter net frame support piece 137 and the outlet frame 139 contact, and the third point (P3). It may have a fourth point (P4) on the exit frame 139 spaced apart in the direction to be.

The elastic member 190 connects the first elastic band 191 to the first point (P1) and the fourth point (P4), and the second point (P2) and the third point (P3) A second elastic band 192 may be provided.

5, when the filter mesh 170 rotates, a first elastic band 191 connecting the first point P1 and the fourth point P4, the second point P2 and the third The second elastic band 192 connecting the point P3 is increased. Since the first elastic band 191 and the second elastic band 192 are made of an elastic material, a restoring force acts when they are relaxed as shown in FIG. 5. The filter mesh frame 135 rotated by the restoring force is returned to its original position.

1, 4A and 5, the second connector 180b may be connected to the filter mesh frame 135 by a fourth rope 184. The fourth rope 184 may have one end connected to the third point P3 of the sieve frame 135 and the other end connected to the second connector 180b. In addition, the second connector 180b may be connected to the fishing boat by the fifth rope 185 and may be connected to the first connector 180b by the connection rope 186.

When the hyeongnet fishing gear 100 normally collects shellfish (S) or when the rake 140 is caught by a fixed obstacle (R), tension may not be applied to the fourth rope 184 and the fifth rope 185 have. As shown in FIGS. 4A and 5, the fourth rope 184, the fifth rope 185, and the second connector 180b sag toward the seabed without applying tension. When the fourth rope 184 and the fifth rope 185 are caught by a flow obstacle other than a fixed object, tension is applied to the filter net 170 to rotate. This will be described later.

In the state of harvesting shellfish (S), the hyeongnet fishing gear 100 moves while the rake 140 scratches the bottom of the sea, and the shellfish S passes through the sieve 170 and is stored in the first net 160. . Shellfish (S) is easily separated from the geology of the ground surface by the yard piece 144, so it can be collected separately from the sea floor.

The rake 140 may set the depth of the rake 140 by adjusting the height of the rotation shaft 130 connected to the first sliding member 110 and the second sliding member 120. Accordingly, the rake 140 may be moved while maintaining a predetermined depth without being deeply embedded in the seabed surface.

The sixth ropes 187a and 187b may connect the second connector 180b and the reinforcing frame 155. The sixth rope 187a may have one end connected to one end of the reinforcing frame 155 adjacent to the first sliding member 110 and the other end connected to the second connector 180b. The sixth rope 187b may have one end connected to the other end of the reinforcing frame 155 adjacent to the second sliding member 120 and the other end connected to the second connector 180b.

The sixth rope (187a, 187b) is in a state in which the hyeongnet fishing gear is operating normally as in FIG. 4A, or as in FIG. In this case, it may be connected without tension between the second connector 180b and the reinforcing frame 155.

However, as shown in FIG. 7, when the rake 140 is caught in a fluid obstacle, and when the fifth rope 185 is pulled to get out of it, the sixth ropes 187a and 187b also have the second connector 180b and the reinforcing frame ( 155) between the tension can act. This will be described later. 6 and 7 are cross-sectional views schematically showing an operating state when caught in other obstacles of the hyeongnet fishing gear of FIG. 1. In detail, FIGS. 6 and 7 are cross-sectional views schematically showing an operating state when caught in a non-fixed flowable obstacle such as a closed net of the fishing gear of FIG. 1.

Referring to FIGS. 6 and 7, there are not only fixed obstacles but also a fluid obstacle W such as a closed net. When the fluidized bed obstacle (W) is caught in the rake 140, the hyeongnet fishing gear 100 does not fail to proceed as shown in FIGS. 4A and 5, and the hyeongnet fishing gear 100 also moves as the fishing vessel advances. However, since the waste net is hung on the rake 140, it interferes with the collection of shellfish (S). Obstruction of the progress of the hyeongnet fishing gear 100 due to the closed net (W) caught in the rake 140, as well as obstacles to the rake 140 through the first rope 181 and the second rope 182 in fishing boats You can detect that this is hanging.

According to an embodiment of the present invention, the fifth rope 185 may be pulled as shown in FIG. 7 in order to remove the flowable obstacle W caught in the rake 140. At this time, the second connector 180b moves toward the ship due to the tension of the fifth rope 185, and tension may also act on the fourth rope 184. One end of the fourth rope 184 is connected to the filter net frame support piece 137 at a third point (P3 in FIG. 4B), and the traction force for the fifth rope 183 is through the fourth rope 184 It is transmitted to the frame support piece 137 so that the filter mesh 170 can rotate.

Due to the rotation of the sieve 170, the pitchfork 140 is also rotated toward the rear end of the hyeongnet fishing gear 100, and accordingly, the fluid obstacle W caught in the pitchfork 140 may be removed. In addition, as shown in FIG. 7, when the hyeongnet fishing gear is caught on a fluid obstacle such as a closed net (W), and pulls the fifth rope 185 to get out of it, the second connector 180b of the fifth rope 185 It moves toward the ship by tension, and the tension acts on the sixth ropes (187a, 187b) between the second connector (180b) and the reinforcing frame 155 to pull the reinforcing frame (155) to pull the fishing gear As an example, the fifth rope 185 may be connected to a reel of a fishing boat, and the fifth rope 185 may be wound around the reel by driving the reel.

8 and 9 are views showing a part of a hyeongnet fishing gear according to another embodiment of the present invention.

8 and 9, the hyeongnet fishing gear may include a spray nozzle unit 240. The spray nozzle unit 240 may inject a fluid to the rake 140 to reduce the resistance of the rake 140. The spray nozzle unit 240 may include a spray nozzle 241, a connection pipe 242, and a pump (not shown).

The spray nozzle 241 may be installed on one side of the rake 140. The injection nozzle 241 may discharge a high-pressure fluid supplied from a pump (not shown). Since the spray nozzle 241 sprays the fluid toward the working direction of the rake 140, it is possible to reduce the resistance of the fishing gear.

The connection pipe 242 may connect a pump (not shown) and the spray nozzle 241 to supply a high-pressure fluid to the spray nozzle 241. A pump (not shown) may be installed at the end of the hyeongnet fishing gear to pressurize the introduced fluid (seawater). A pump (not shown) may be installed on one side of the strainer 170. The pump (not shown) is fixed to the filter screen frame 135 and can rotate together when the filter screen 170 is rotated.

10 is a cross-sectional view schematically showing a hyeongnet fishing gear 300 according to another embodiment of the present invention.

Referring to FIG. 10, the hyeongnet fishing gear 300 may rotate the sieve 170 using the driving unit 310. As an example, the driving unit 310 may include a motor 311 and a wire rope 312. The motor 311 is installed on the strainer frame support piece 137, and the wire rope 312 has one end connected to the motor 311, and the other end connected to the connecting frame 127. The other end may be connected to the first point (P1 in FIG. 4B) of the connection frame 127.

The motor 311 may be controlled by an operator. When the hyeongnet fishing gear 300 is caught by an obstacle on the seabed and the sieve 170 rotates and passes an obstacle as shown in FIG. 5, or when the sieve 170 is rotated and the obstacle is removed to remove a fluid obstacle as in FIG. In order to collect shellfish, the strainer 170 must be returned to its original position. When the motor 311 is driven while the strainer 170 is rotated, the motor 311 winds the wire rope 312. Since the other end of the wire rope 312 is fixed to the first point P1 of the connection frame 127, the filtering net 170 can be rotated back to its original position as the wire rope 312 is wound around the motor 311. have.

Since the hyeongnet fishing gear according to an embodiment of the present invention can rotate when it collides with an obstacle R on the sea floor, durability is improved and it can be easily stored and maintained. The hyeongnet fishing gear can easily get out of the obstacle (R) and thus improve mobility.

The hyeongnet fishing gear according to an embodiment of the present invention can maintain a horizontal level even with a change in the depth of the seabed. Even if the water depth changes due to the first connector 180a, the first rope 181, the second rope 182, the rotation control unit 150, and the rotation bar 151 connected to the fishing boat, the first sliding member and the second This is because the sliding member is in contact with the sea floor without changing the height. In other words, even if the water depth changes, it does not affect the height of the fishing gear at all.

The hyeongnet fishing gear according to an embodiment of the present invention can store shellfish (S) while separating shellfish (S) from sand. Since the first mesh 160 has a narrow outlet end and a wide mesh, the sand introduced from the rake 140 can be discharged back to the outside. The shellfish S may be stored in the first mesh 160 by passing through the filter mesh 170.

In the hyeongnet fishing gear 100 according to an embodiment of the present invention, the rake 140 is formed to be bent in the front so that the resistance by the geology of the seabed can be minimized, so that shellfish (S) can be easily collected, and the rake 140 ), the durability can be improved by reinforcing the rigidity between them.

11 is a schematic cross-sectional view showing a hyeongnet fishing gear according to another embodiment of the present invention. Referring to FIG. 11, the hyeongnet fishing gear 400 may further include a support member 410. The support member 410 may have one end attached to the connection frame 127 and extend toward the sea floor. The support member 410 may be positioned between the sea floor and the support member 410 when the hyeongnet fishing gear 400 sinks to the sea floor to prevent the rake 140 from digging into the sea floor.

Specifically, when the hyeongnet fishing gear 400 enters the sea and is submerged to the bottom of the sea, depending on the weight of the weight 195 disposed on the sieve 170, the rake 140 is located in the hyeongnet fishing gear 400 Rather than the front end, the rear end of the hyeongnet fishing gear 400 where the weight 195 is located may first touch the sea floor. When the rear end of the hyeongnet fishing gear 400 first touches the sea floor, the rake 140 may prevent the end of the rake 140 from being lodged on the sea floor toward the sea level. If the rake 140 does not get stuck in the bottom of the sea, it is impossible to mine shellfish (S) in the bottom of the sea.

The support member 410 according to an embodiment of the present invention is disposed on the connection frame 127 adjacent to the weight 195 to prevent the rear end of the hyeongnet fishing gear 400 from contacting the sea floor. Even if the rear end of the hyeongnet fishing gear 400 is first sunk by the weight 195, the support member 400 is supported between the sea floor and the connecting frame 127 to prevent the front end of the hyeongnet fishing gear 400 from being lifted toward the sea level can do. Accordingly, the rake 140 can be easily lodged on the sea floor.

As an example, the support bag 410 may include a first member 411, a second member 412, a hinge part 413, a pedestal 414, and a support connection member 415.

The first member 411 may be coupled to the connection frame 127 to face the sea floor. One end of the first member 411 is coupled to the connection frame 127, and the other end may face the sea floor.

The second member 412 may be hinged to the other end of the first member 411. That is, the second member 412 and the first member 411 may be connected by the hinge part 413. The second member 412 is rotatable by the hinge part 413. The second member 412 may be positioned in the same direction as the longitudinal direction of the first member 411 and may rotate toward the rear end of the hyeongnet fishing gear 400.

The hinge portion 413 allows the second member 412 to rotate toward the rear end of the hyeongnet fishing gear 400 and may prevent rotation toward the front end of the hyeongnet gear 400.

A pedestal 414 may be disposed at one end of the second member 412 facing the hinge part 413. The pedestal 414 may directly contact the sea floor when the second member 412 is arranged in line with the first member 411. That is, the pedestal 414 may support the hyeongnet fishing gear 400 with respect to the sea floor.

The pedestal 414 may have a plate shape to support the hyeongnet fishing gear 400 against the sea floor.

The support connection member 415 may connect the second member 412 and the connection frame 127. The support connecting member 415 has one end connected to the connecting frame 127 toward the front end of the hyeongnet fishing gear 400 than the first member 411, and the other end is coupled to the support 414 and the second member 412 It can be connected to the part that becomes.

The support connecting member 415 may have elasticity. The support connecting member 415 may elastically act on the second member 412 so that the second member 412 is arranged in line with the first member 411 even when the second member 412 rotates at a predetermined angle. I can.

When the second member 412 is further rotated and the angle with the first member 411 is smaller than a predetermined angle θ1, the support connecting member 415 applies an elastic force to maintain the rotated state of the second member 412. Can work. The predetermined angle θ1 is an angle between the first member 411 and the second member 412 when the support connecting member 415 and the second member 412 are aligned.

When the angle between the first member 411 and the second member 412 is greater than a predetermined angle θ1, the support connecting member 415 is aligned with the first member 411 with respect to the second member 412. When the elastic force acts in the direction to be, and the angle between the first member 411 and the second member 412 is less than a predetermined angle θ1, the second member 412 is the first member 411 An elastic force acts in a direction pulled to the side so that the second member 412 may be kept folded.

Specifically, after the hyeongnet fishing gear 400 first sinks to the seabed, it proceeds in the moving direction of the ship by the ship. Even while the hyeongnet fishing gear 400 is advancing, if the pedestal 414 touches the sea floor, friction between them may occur. Since the second member 412 is hinged with the first member 411, when the hyeongnet fishing gear 400 advances, the second member 412 rotates in a direction opposite to the traveling direction of the hyeongnet gear 400.

When the degree of rotation of the second member 412 is small, and the angle between the first member 411 and the second member 412 is greater than a predetermined angle (θ1), the support connecting member 415 is the second member 412 ), the elastic force acts in the opposite direction of the rotation so that it is in line with the first member 411.

However, when the degree of rotation of the second member 412 is large, the support connecting member 415 maintains a state in which the second member 412 rotates due to an elastic force acting in the direction in which the second member 412 rotates. Do it. Since the second member 412 is maintained in a rotated state, the pedestal 414 does not contact the sea floor while the hyeongnet fishing gear 400 is advancing, thereby reducing unnecessary friction when the hyeonggu fishing gear 400 proceeds. have.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications or variations without departing from the spirit and scope of the invention. Accordingly, the scope of the appended claims will include such modifications or variations as long as they fall within the gist of the present invention.
