[0001] APPARATUS FOR SEPARATING FISH FROM NETWORK [0002]

The present invention relates to a fish separating apparatus, and more particularly, to a fish separating apparatus for separating fish from a cannula capable of automatically separating small fish such as anchovy captured mechanically by vibrating the net.

Anchovy is a representative fish species in the coast near Korea, where it enters the coast in the spring, which is the spawning season, and then goes to the southern sea in the fall and spends winter.

Anchovy fishing is a traditional method of lifting a net on the coast near the coast, and it is a traditional method of fishing. This method involves loading a net on a ship, putting one end of the net and the end of the net on the coast, It is how many people pull both ends of the shore and pull the net up to the shore.

In addition, the widowed word is a towel-shaped net laid out vertically, and the fish is caught in the net, so that the fish is caught. This phrase is called a hanging or netting, and an anchor is placed at the end of the net. In some cases, it is fixed, but it is common to catch the net while letting it flow according to the tide.

After the anchovy has been done in various ways, the fishing boat is anchored in the harbor, and anchovies are put in the box and then the anchovies attached to the net are shaken off or anchovies are kept for at least 3-4 hours to clean the net for the next fishing. The hair is working.

This anchovy hair work is one of the most difficult and difficult thing in the anchovy process. It is a group of 7 ~ 8 people per fishing boat. It shakes up and down the net and it is very strong. In case of input, it is economically difficult for fishermen due to excessive labor loss and working time consumption.

Particularly, due to unstable hitting power due to manpower, part of the anchovy was severed or damaged and it became a factor to lower the quality as food.

In addition, the anchovy hairs were scattered in four directions, and hair, internal organs and blood were separated to form an oil band on the coast.

In addition to anchovies, small fish such as herring, codfish, horse mackerel, and hornet are also the same problems when they are trapped by the net.

In the following description, a detailed description of related arts will be omitted when it is determined that the gist of the present invention may be unnecessarily blurred.

FIG. 1 is a front view showing the overall structure of an apparatus for separating fish from a lucerne net according to an embodiment of the present invention, and FIG. 2 is a plan view of the present invention shown in FIG.

The present invention relates to a device capable of shaking off fish by repeatedly impacting the net while feeding the net in a unfolded state at a constant speed in order to separate fish such as anchovy trapped by the net.

Referring to FIG. 1, the present invention may include a support frame 400, a snatch recovery unit 300, a first vibration unit 100, and a second vibration unit 200. In the present invention, the net (n) is a rectangular net and has ropes (r) on both sides, and the ropes have a plurality of weights or buoys at regular intervals.

First, the support frame 400 supports the lancet recovery unit 300, the first vibration unit 100, and the second vibration unit 200 so that a plurality of beams are connected to each other It may be a shape that forms a rectangular skeleton.

The lancet collecting unit 300 is installed in front of the support frame 400 to draw the lancet n in an open state and a first vibrating unit 100 is installed at the center of the support frame 400, the second vibrating part 200 is provided behind the support frame 400 in which the nip n is introduced and the nip n is periodically impacted by the second vibrating part 200, To generate vibration.

At this time, the width of the support frame 400 may be approximately the same as the width of the weir mesh n.

The napkin (n) is fed to the lancet collecting unit (300) while being transferred from the upper side of the second vibrating unit (200) and the first vibrating unit (100).

Next, with reference to Figs. 3 and 4 together, the lancet network collecting unit will be described.

FIG. 3 is a detailed structural view showing the detailed structure of the lancet returning unit of the present invention shown in FIG. 1, and FIG. 4 is a side view of the lancet collecting unit of the present invention shown in FIG.

The lancet recovery unit 300 is provided on both sides of the support frame 400 and pulls the ropes r on both sides of the lancet network n to remove the recovery motor 310, the support bracket 360, 320, and an elastic rotating body 330.

The support bracket 360 is fixed to both sides of the front side of the support frame 400. The support bracket 360 may be an 'angled' angle.

A wheel 320 is rotatably mounted on the support bracket 360.

The wheel 320 has a shape similar to that of a pulley or a pulley and may have a groove 320a formed inwardly concave so that the rope r can be inserted and adhered along the outer periphery.

A recovery motor 310 is provided at one side of the wheel 320. The motor shaft of the recovery motor 310 may be directly connected to the wheel 320 by a coupling 370 so as to be rotationally driven.

The recovery motor 310 may use a hydraulic motor to output a large power.

Further, an elastic rotating body 330, which is rotatably installed on the wheel 320, may be provided. The elastic rotating body 330 may have a circular shape and an elastic material such as rubber may be attached along the outer periphery of the elastic rotating body 330. The elastic rotating body 330 is connected to the outer periphery of the wheel 320 and rotates together.

That is, the outer circumference of the elastic rotation body 330 is installed in close contact with the contact groove 320a of the wheel 320 so that the elastic rotation body 330 is interlocked by the wheel 320 rotating desirable. At this time, the contact groove 320a is recessed inwardly and the outer circumference of the elastic rotation body 330 may be rounded so as to be seated in the contact groove 320a.

Therefore, when the rope r of the lancet n is pulled in between the rotating wheel 320 and the elastic rotation body 330, the lancet r can be transported by frictional force and the lancet n can be recovered.

For reference, the elastic rotating body 330 may use a tire.

However, buoys w or weights w can be inserted between the elastic rotation body 330 and the wheel 320 at a predetermined interval. In order to prevent this, a tension spring 350 may be provided so that the gap between the elastic rotation body 330 and the wheel 320 is elastically expanded and restored.

That is, one end may be hinged to the support bracket 360 so as to be rotatable, and a lever 340 may be further provided at the center of which the elastic rotation body 330 is rotatably coupled.

A tension spring 350 is installed between the other end of the lever 340 and the support bracket 360. Therefore, as the lever 340 rotates about the hinge engaging portion h, the elastic rotating body 330 can be closely contacted with or spaced from the wheel 320, The spring 350 maintains the elastic rotation body 330 in a state in which it is in close contact with the wheel 320.

If the elastic rotating body 330 and the wheel 320 are further drawn in, the tension spring 350 is stretched to separate the elastic rotating body 330 and the wheel 320 from each other, The elastic rotating body 330 is brought into close contact with the wheel 320 while being returned by the restoring force of the tension spring 350 again.

Therefore, the rope (r) can be stably recovered without being caught or removed when the retractor is retracted.

The lever 340 may use a '-shaped link as shown.

On the other hand, since the elastic rotating body 330 is further provided on one side of the wheel 320, the heavy net thread can be pulled out with sufficient force to be recovered.

It is needless to say that a lever and a tension spring must be additionally provided in order to further include the elastic rotating body 330.

The width of the contact groove 320a of the wheel 320 should be larger than the outer diameter of the buoy or the weight w. This is because the buoy or the weight w can be taken in while being completely accommodated in the contact groove 320a.

Next, the first vibration unit 100 will be described.

The first vibrating unit 100 is disposed between the lancet collecting unit 300 and the second vibrating unit 200. The lancet collecting unit 300 periodically collects the lancet net n transferred from the lancet collecting unit 300 And at the same time, the lancet n is brought into the lancet collecting unit 300 in a completely unfolded state without being folded or folded, so that it can be recovered.

The first rotary shaft 110 constituting the first vibration unit 100 is disposed horizontally across the support frame 400 and rotated.

A first driving motor 120 is provided at one end of the first rotating shaft 110 to rotate the first rotating shaft 110. The first driving motor 120 may be a hydraulic motor.

A circular first rotary plate 130 is coupled to both ends of the first rotary shaft 110 to rotate together with the first rotary shaft 110.

Also, a pair of first rotating bars 140 are provided between the first rotating plates 130 and rotated together. The first rotating bar 140 may be a circular pipe or a circular rod, and is horizontally disposed in parallel with the first rotating shaft 110, and is fixed to face each other so as to face each other.

Accordingly, the pair of first rotating bars 140 and the first rotating shaft 110 are positioned on the same plane. As the first rotating shaft 110 rotates, the first rotating bars 140 alternately (N) is generated from the lower side to generate vibration.

Any or all of the first rotating bars 140 may be inwardly inclined from the center to the outer side. That is, the first rotating bar 140 is folded at a predetermined angle at a central point of the first rotating bar 140 so that the first rotating bar 140 is higher in price when the napkin n is priced, As the price is lower, so that the net can be fully unfolded.

A supporting plate 150 is further provided between the first rotating shaft 110 and the first rotating bar 140 to support the first rotating bar 140 and to rotate the first rotating bar 140 while the first rotating bar 110 rotates, It is possible to prevent the rotation bar 140 and the first rotation shaft 110 from becoming entangled.

Next, the second vibrating unit 200 has a structure similar to that of the first vibrating unit 100.

The second vibrating unit 200 is provided at the rear of the supporting frame 400, that is, at the entry point of the weir mesh n, and is composed of a second rotating shaft 210, a second driving motor 220, A first rotating bar 230, and a second rotating bar 240.

The second rotation axis 210 is disposed horizontally across the rear of the support frame 400 and rotates.

A second driving motor 220 is provided at one end of the second rotation shaft 210 to rotate the second rotation shaft 210. The second drive motor 220 may be a hydraulic motor.

A circular second rotary plate 230 is coupled to both ends of the second rotary shaft 210 to rotate together with the second rotary shaft 210.

Further, a pair of second rotating bars 240 are provided between the second rotating plates 230 to rotate together. The second rotating bar 240 may be a circular pipe or a circular rod, and is horizontally disposed parallel to the second rotating shaft 210, and is fixed to the opposite side so as to face each other.

Accordingly, the pair of second rotating bars 240 and the second rotating shaft 210 are positioned on the same plane. As the second rotating shaft 210 rotates, the second rotating bars 240 alternately It causes vibrations by lowering the net from the net.

Also, one or more supporting bars 250 may be coupled between the second rotating bars 240 facing each other.

Here, the second rotation axis 210 rotates in a direction opposite to the first rotation axis 110. The first rotating shaft 110 rotates toward the lancet returning unit 300 and the second rotating shaft 210 rotates in a direction in which the lancet network enters. Referring to FIG. 1, the first rotation axis 110 rotates counterclockwise and the second rotation axis 210 rotates clockwise.

The phases of the first rotating bar 140 and the second rotating bar 240 are rotated 90 ° apart from each other. In other words, the first rotating bar 140 and the first rotating shaft 110 are rotated while the second rotating bar 240 and the second rotating shaft 210 are perpendicular to each other .

This is to apply alternating vibrations to the front and back of the net (n). In other words, it forms a wave on the net and induces the fish to shine well.

At this time, the interval between the second rotating bars 240 is larger than the interval between the first rotating bars 140, so that vibrations can be applied while forming a larger amplitude of the louver network.

Hereinafter, the operation of the present invention will be described with reference to FIG.

5 is an operational state diagram of the snatch recovery unit of the present invention.

The ropes r of both ends of the tip of the napkin (n) from which the fish are captured are drawn between the elastic rotation body 330 and the wheel 320 of the respective lancet recovery units 300 and then the recovery motor 310 is driven .

When the wheel 320 rotates by the driving of the recovery motor 310, the elastic rotating body 330 which is connected to the rotating wheel 330 also rotates together. As the drawn rope r is drawn out to the opposite side by friction, Lt; / RTI >

At this time, the number of revolutions of the recovery motor 310 can be rotated to approximately 6 rpm.

At the same time, when the first driving motor 120 and the second driving motor 220 are operated, the first vibrating unit 100 and the second vibrating unit 200 start operating.

That is, the second rotating bar 240, which rotates at a phase difference of 90 degrees successively, generates vibration by charging the back of the orbital net (n) through which the first rotating bar 140 enters, And the process of generating vibration by alternately repeating the process of generating the vibration. Because of this, fish can be almost separated from the net.

The number of rotations of the first rotation shaft 110 and the second rotation shaft 210 can be rotated to about 120 rpm.

Here, when the weight or the buoy w hanging from the rope r of the weftnetwork is drawn between the elastic rotation body 330 and the wheel 320, the elastic rotation body 330 is pushed, And the tension spring 350 is also increased.

When the weight or the buoy w is drawn out, the tension spring 350 is restored and the elastic rotating body 330 is brought into close contact with the contact groove 320a of the wheel 320 to pull the rope r .

Therefore, it is possible to reliably recover without losing or stopping the lancet network due to the weight or the buoy (w).
