The present invention relates to a small fish sorter and a small fish sorter for selecting from a mixture of large fish having a width and a height larger than those of medium fish and small fish.

[0002]

[Prior art]

 Conventionally, in order to select extremely small and slender small fish, such as whitefish and juvenile black sardines, which are the materials for chili menjaco, from other medium fish, as shown in Fig. 13, a hole with a diameter of 2 mm to 2.5 mm is used. A punching plate 51 having a plurality of openings 52 is arranged above the small fish container 53, and a small fish 54 harvested together with other medium fish 55 and large fish 56 is poured onto the upper surface of the punching plate 51 to have a diameter of 1 mm or more. The small fish of about 2 mm are discharged together with water from the holes 52 having a plurality of openings into the small fish container 53 below, and the small fish are housed in the container 53, and other small fish that cannot pass through the hole 52 are discharged. The medium fish 55 and the large fish 56 were stored in another medium and large fish container 57, and the small fish 54 were sorted. However, in the selection by the punching plate 51, if pressure is applied to the small fish 54 due to water pressure or contact with other medium fish 55 or large fish 56 while the small fish 54 pass through the holes 52 of the punching plate 51, The small fish 54 were cut by the punching plate 51, and cut pieces and damaged small fish 54 were mixed in the selected small fish 54. Moreover, the holes 52 of the punching plate 51 were clogged with the cut pieces of small fish, and the selection efficiency was deteriorated.

[0005]

[Action]

 According to the present invention, a person can hold a small fish selector with the small fish intake groove on top by hand or use a support tool to place it above the container for storing the selected small fish. , Small and slender small fish to be sorted, medium fish larger than this small fish, and large fish wider or taller than the small fish mixed in the water. Pour onto the top of the sorter. The small fish and medium fish that have been poured are guided along with the water along the longitudinal direction of the small fish intake groove into the whole body of the small fish intake groove, but it becomes difficult for the medium fish to pass through the passage in a substantially orthogonal part. On the other hand, small fish pass through a passage in a substantially orthogonal part together with water and are discharged together with water into a container arranged below the small fish extraction groove for sorting. If the height of the passage in the substantially orthogonal portion is substantially the same as the height of the small fish selected according to claim 2, the medium fish passes through the passage in the substantially orthogonal portion in the small fish intake groove. It is not possible to do so, and it is held in the small fish intake groove. However, since small fish can pass through the passage of this bent portion, they pass along with the water along the passage in the main body of the sorter to the small fish removal groove, and together with the water enter the container placed below from the small fish removal groove. It will be discharged. In this way, small fish are sorted, and medium fish retained in the small fish intake groove of the small fish sorter, and small fish remaining on the upper surface of the small fish sorter without entering the small fish intake groove. Large fish can be easily sorted into small fish, medium fish and large fish by moving them to another container. During sorting, the small fish are guided into the small fish intake groove, so that some small fish are not cut by the small fish sorter due to other small fish, medium fish, or water pressure. The small fish passed smoothly through the small fish sorter and there was no need to worry about damaging the small fish. Furthermore, since the small fish intake groove for taking in the small fish to be selected is long and slender, the slender small fish can be easily passed through the small fish selector. By repeating these steps, a large number of small fish can be easily selected. As described in claim 4, if each of the longitudinal sides of the peripheral edge of the small fish intake groove is provided with a protrusion, the small fish and the medium fish hitting the protrusion are guided into the small fish intake groove. . As described in claim 5, if the passages in the substantially orthogonal portion are provided in a communicating state, the small fish passing through the substantially orthogonal portion may be discharged from any one of the plurality of small fish extraction grooves. Even if a small fish gets stuck in the passage after it is almost orthogonal, the small fish intake groove through which the small fish has passed does not become closed, and the small fish should pass to another small fish removal groove. The efficiency of sorting work is not reduced.

In the small fish sorter according to the third aspect, small fish and medium fish are guided into the small fish intake formed in the gap between the first rods, and the small fish below the small fish intake. In contact with the flat upper surface of the second rod at the position, small fish and medium fish are located between the first rods, and the gap between the first rod and the second rod is slightly wider than the height of the small fish. As a result, the medium fish cannot pass through the gap provided between the first rod and the second rod, and is located as it is between the first rods. However, the small fish pass through the gap between the first rod and the second rod, are discharged from the small fish outlet formed in the gap between the second rods, and are stored in the lower container to complete the sorting. The medium fish and large fish remaining on the upper surface of the first rod may be stored in another container. Furthermore, since the small fish intake groove for taking in the small fish to be sorted is elongated, it is possible to easily pass the slender small fish through the small fish sorter. If the top of the bar is raised, the small fish and medium fish hitting the first bar with this high bar will be efficiently guided to the small fish intake between the first bars. The small fish sorter may be horizontal or tilted. When small fish, medium fish, and large fish in a mixed state are poured onto the upper surface of the small fish sorter, they may be poured along the small fish intake groove or the small fish intake opening, or may be poured in an orthogonal state.

In the small fish sorter according to any one of claims 8 to 13, the small fish sorter according to any one of claims 1 to 7 is provided in a plate shape, a U shape, or a cylindrical shape in the transport direction. On the other hand, the small fish intake groove or the small fish intake port is provided in a substantially parallel state or a substantially orthogonal state in the bottom wall of the obliquely installed transport path or in the middle or end of the transport path. Further, the above-mentioned cylindrical transport path may be provided horizontally for use. If the small fish, medium fish, and large fish are mixed and poured into the transport path, the small fish, medium fish, and large fish approaching the small fish sorter Through this small fish sorter, a chute provided below the transport path guides the fish to a predetermined position. If a container is placed at the end of the chute, the selected small fish can be easily collected in the container. Medium and large fish that could not pass through the small fish sorter slides down to the end of the transport path. If another container is placed at the end of the transport path, medium and large fish can be easily stored. Furthermore, since the small fish intake groove for taking in the small fish to be selected is long and slender, the slender small fish can be easily passed through the small fish sorter, which improves the sorting work efficiency.

[Effect of device]

 As described above, in the small fish sorter of the present invention, the width of the small fish intake groove or small fish intake is set to be slightly wider than the width of the small fish to be selected. Larger fish cannot enter this small fish intake groove or small fish intake. In addition, medium fish with a width almost the same as the width of the small fish to be selected and a height higher than that of the small fish can enter the small fish intake groove or the small fish intake, but the small fish can be taken in by a substantially orthogonal passage. Since it is difficult to pass through the groove or small fish intake port, small fish can be selectively passed from the mixed state to the small fish extraction groove or small fish intake port to easily and reliably catch small fish. You can sort out. In addition, the small fish intake groove or small fish intake port is long and narrow, so small fish that are long and narrow can easily pass through, improving the sorting work efficiency. If the height of the passages that are substantially orthogonal to each other is set to be substantially the same as the height of the small fish to be selected as in claim 2, the middle fish that have entered the small fish intake groove are surely blocked and the selection is made. Only small fish that are discharged can be discharged to the small fish removal groove, and only small fish can be reliably selected. If protrusions are provided on the respective sides in the longitudinal direction of the peripheral edge of the small fish intake groove as described in claims 4 and 7, or if the vertexes of every other first rods are raised, the protrusions and vertexes The first rod, which has a high height, can guide the small fish into the small fish intake groove or the small fish intake opening, and improve the efficiency of the sorting operation. As described in claim 5, if the passages of the adjacent substantially orthogonal portions are provided in a communicating state, the small fish passing through the substantially orthogonal portion may be discharged from any one of the plurality of small fish extraction grooves. Even if a small fish or medium fish that has entered the small fish intake groove is blocked in the passage, the small fish intake groove that the jammed small fish or medium fish passes through does not become a closed state, and the passage is different. Since it is possible to sort using, the efficiency of sorting work can be greatly improved.

According to the small fish sorter according to any one of claims 8 to 13, since the small fish sorter according to any one of claims 1 to 7 is provided at the bottom wall of the transport path or in the middle or at the end. If small fish, medium fish, and large fish are poured into the transport route in a mixed state, the small fish sorter can easily and reliably select small fish from medium fish and large fish. In addition, the small fish, medium fish, and large fish in a mixed state that are transported by other processes are connected to other processes so that they flow to the transport route, and the selected small fish are processed by the chute through another process. If you connect to other processes such as guiding middle and large fish that slide down to the end of the transport path to other processes, a large amount of small fish selected will be required in other processes Even in such a case, a large amount of small fish can be quickly and surely selected and efficiently supplied to other processes.
