The present invention relates to an automatic sorting device for shrimp caught in a fishing net comprising a size sorting unit, a sorting optimization device for making the posture of the catch a favorable posture for sorting, and a shrimp sorting part for separating the shrimp and fish mixed in the catch.

There are more than 1,000 fisheries that catch shrimp, and the catch is a mixture of shrimp and catch fish. At the fishery site, separate labor costs are paid to sort the mixed fish and shrimp, and the manual work is repeated for a long time. In addition, in the case of manual sorting as described above, it is difficult to ensure the accuracy of sorting due to the skill and individual differences of the workers, it is difficult to maintain the consistency of the sorting state, and it is difficult to maintain the uniformity of the sorting size according to the region.

Therefore, in order to select shrimp and mixed fish and to provide only highly marketable shrimp as a product, a device for selecting shrimp that can be automatically selected and replaced by manpower is required.

However, the shrimp had a problem in that it was difficult to mechanize the sorting operation due to the various characteristics of the captured shape, such as a straight straight (1 character) shape, a curved L (ㄱ character) shape, and a round pentagon (ㅇ) shape. As a related prior art, Registered Patent No. 10-0455514 discloses a sorting machine that can be accommodated in a sorting hole perforated in the conveyor belt while shrimp put into a conveyor vibrating by the installation of a vibrating motor and can be sorted. The technology is a device for sorting shrimp by size in the stage of screening only shrimp, and it is insufficient to select fish and shrimp mixed with fish as in the present invention.

In order to solve this problem, the present inventors used the difference in surface friction between soft-skinned fish and hard-skinned shrimp in the process of studying the characteristics of mixed fish and shrimp.

Based on these results, the conveying table including the uneven plate reciprocates left and right, optimizing the irregularly placed shrimp and other fish in an easy-to-sort position, and the soft-shelled fish transported on the inclined conveyor belt is uneven. It was possible to develop a sorting machine that was caught and rotated on a conveyor belt, passed through the belt shaft, and fell down.

The automatic sorting device for shrimp mixed in a fishing net according to an embodiment of the present invention includes a size sorting unit, a sorting optimization device having a transfer unit that makes the posture of the catch in an advantageous position for sorting, and a shrimp sorting device that separates the shrimp and fish mixed in the catch It may consist of wealth.

1 shows a schematic diagram of an automatic sorting apparatus for shrimp mixed in a fishing net of the present invention. In the size sorting unit of the present invention, catches of a size similar to that of shrimp are first selected using a vibrating sieve, and in the transfer unit, shrimp and other fish species that are placed irregularly are selected while the conveyor including the uneven plate reciprocates from side to side. It may be selection by optimizing for an easy posture.

The shrimp sorting unit of the present invention is composed of a conveyor belt that has irregularities on the surface and is placed at an angle. The fish with a soft skin gets caught on the irregularities and rotates on the conveyor belt, passes the belt shaft and falls down. It may be classified as it slides down the slanted uneven surface of

Figure 2 shows a schematic diagram of the size sorting device constituting the automatic sorting device for shrimp mixed in the fishing net of the present invention. The size sorting device is configured as shown in FIG. 2-A, and the catch is supplied to a funnel-shaped space (refer to FIG. 2-C) built into the upper part of the device. It passes between a plurality of cylindrical rods configured as shown in FIG. 2-B inside and falls down as shown in FIG. 2-C, and catches larger than the distance between the rods are filtered in a primary way.

For large individuals that cannot pass through the rod, the size sorting device is tilted to one side as shown in FIG. 2-C, so catches of a size that can pass through the rod and those that do not are naturally divided, and the inclination direction of the sorting device eventually fall off. After passing through the rod, the small fish and shrimp are sorted again into small fish and shrimp in a sorting optimization device comprising a transport platform as described below.

A vibration generating device as shown in FIG. 2-E is mounted on the top of the size sorting device as a means to increase the sorting performance of mixed catches that have fallen on the rod. An example may be a method in which a plastic resin is eccentrically mounted on a motor rotating shaft and rotated.

The thickness of the rod constituting the size sorting device is appropriate to be 1 to 2 cm in diameter, and the spacing between the rods is considered to be the thickness of the shrimp shown in Fig. It is appropriate to set it to 1~2cm, which is the possible size range. However, this interval can be adjusted depending on the size of the fish being caught.

Figure 3 shows a schematic diagram of a sorting optimization device including a transfer table constituting the automatic sorting device for shrimp mixed in the fishing net of the present invention. The sorting optimization device including the transfer stand is a device to improve the sorting performance before sorting the shrimp and fish mixed in the catch. sending device.

As shown in FIG. 3, the sorting optimization device including a transporter consists of a transporter made of a reciprocating panel and a concave-convex plate, a guide rail, a wheel, a driving motor, a crank, a connecting rod, and a support. The reciprocating panel consists of a plate made of stainless steel, iron, and plastic with a thickness of 1 to 8 mm, and the concave-convex plate is placed on this panel.

Concave-convex plate is a plate in which irregularities are arranged uniformly, and the material is plastic or metal. It can be any of the possible three-dimensional shapes and combinations thereof.

The spacing and height of the irregularities are 1~10mm and 0.1~10mm, respectively, and the thickness of the irregularities is 0.1~5mm based on the cross-sectional diameter of the upper and lower surfaces of the solid constituting the irregularities or the length of one side (however, conical) Or a solid with a pointed end, such as a quadrangular pyramid, is based on the base).

The guide rail and wheel are devices that maintain a linear motion when the reciprocating panel reciprocates from side to side. is composed of

The crank is a rotating disc connected to the driving motor. The central axis of this disc is fixed to the driving motor and there is another rotating shaft eccentric from the central axis, so this shaft is connected to the connecting rod through a bearing. . The connecting rod is a stainless steel or iron rod that connects the crank and the reciprocating panel through bearings, respectively.

The inclination of the reciprocating panel is 5 to 45 degrees, and the inclination can be adjusted through the angle guide and set screw attached to the support. The reciprocating cycle of the reciprocating panel is 2 to 10 times per second, and the reciprocating distance is 5 to 50 cm.

If the mixed catch is dropped directly onto the shrimp sorting belt without going through a sorting optimization device that includes a transport platform, the shrimp will easily slide off the uneven plate when the tail is down, but if the head is down, the stubble There is a problem that the horns and horns get caught in the irregularities and do not go down. 4 shows a function for screening shrimp and fish in the selection optimization device.

As a means to solve this problem, as shown in FIG. 3, if a shrimp is placed on an uneven plate inclined at a certain angle to one side and shaken left and right, the shrimp rotates around the uneven part with a beard or horn as an axis, and the tail is directed downward. It slides easily on the uneven plate (Fig. 4-A).

In addition, anchovy or mackerel among fish has a problem of mixing with shrimp because the cross section is close to an ellipse or circle, and when placed perpendicular to the direction of transport, it rolls down without obtaining frictional force. This problem also occurs when, as shown in Fig. 4-B, when fish such as anchovy or mackerel are placed on the uneven plate constituting the selection optimization device including the transfer table and shaken left and right, as shown in Fig. 4-B, the transfer direction and In the process of shaking the vertically placed fish, the posture is changed in parallel with the direction of transport to solve the problem of rolling. As such, when the fish are placed in parallel with the transport direction, the frictional force increases, so that separation is possible using the difference in frictional force with the shrimp, which has a relatively low frictional force.

5 is a schematic diagram of a shrimp sorting belt constituting an automatic sorting device for shrimp caught in a fishing net of the present invention. As shown in FIG. 5, the shrimp sorting belt is composed of two rotating shafts, and a conveyor belt having a certain inclination, a plate with irregularities installed on the belt, a support for supporting the conveyor belt, and a motor for driving the conveyor belt.

Figure 5-B shows an example in which the concave-convex plate is placed on the bracket of the conveyor chain. The conveyor belt consists of a conveyor chain, four sprockets that rotate the chain, and two rotating shafts as shown in FIG. 5-B. The conveyor chain is a chain provided with a bracket perforated so that a metal or plastic plate can be coupled to the chain using a screw or the like as shown in FIG. 5-C, and the concave-convex plate is coupled on the bracket.

However, when the concave-convex plate is made of plastic, the strength is weak, so a method of arranging a stainless steel or iron flat plate on a bracket and arranging a plastic concave-convex plate on the bracket may be another configuration example.

Figure 5-D shows the uneven plate constituting the shrimp sorting belt of the present invention. Concave-convex plate is a plate in which irregularities are arranged uniformly, and the material is plastic or metal. It can be any of the possible three-dimensional shapes and combinations thereof.

The spacing and height of the irregularities are 1~10mm and 0.1~10mm, respectively, and the thickness of the irregularities is 0.1~5mm in length based on the cross-sectional diameter of the upper and lower surfaces of the solid constituting the irregularities or the length of one side (however, conical) Or a solid with a pointed end, such as a quadrangular pyramid, is based on the base).

The inclination of the shrimp sorting belt with the concave-convex plate on the bracket of the conveyor chain may be 20 to 60 degrees. Since the shrimp sorting belt is a device that separates by using the difference in the friction coefficient of the outer skin between shrimp and fish, it can be configured not only in the form of a conveyor belt, but also in various means to which the concave-convex plate can be attached while rotating, such as a drum.

6 shows the selection principle using the difference in the friction coefficient of the outer skin. The shrimp sorting belt is composed of a conveyor belt that has irregularities on the surface and is placed at an angle. As shown in FIG. 6, fish with a soft outer skin are caught on the irregularities and rotate clockwise on the conveyor belt. Hard shrimp are sorted by sliding down the inclined surface (in the opposite direction to the conveyor rotation).

The shrimp sorting unit may be composed of various means to which the concave-convex plate can be attached while rotating, such as a drum as well as a conveyor belt. (See FIG. 7) A schematic diagram of the sorting device is shown. Fig. 8-B shows an example of an inclined conveyor belt arrangement with a stopper for feeding catch to the arrangement of Fig. 8-A;

The sorting device that can separate soft-shelled fish and hard-skinned shrimp using the difference in surface friction force has proven its shrimp sorting performance through experiments. Therefore, there is potential for industrial application.
