Description

[0001]
[Industrial application fields]
The present invention relates to a fish sorting apparatus for sorting large and small fish on various large and small fishing boats or on land after landing a fish.
[0002]
[Prior art]
Although there are many types of conventional fish sorting apparatuses, they are particularly unsuitable for small fishing boats due to their large size and complicated mechanism.
For example, in the description of Japanese Patent Laid-Open No. 7-203798, driving means such as a belt conveyor is provided for transporting fish onto a horizontal sorting tank (separator filter), or as described in the specification of Japanese Patent No. 263129. In addition, most of the mechanisms are complicated, such as a zigzag sorting passage extending vertically and a pneumatic feeding means therefor.
In addition, as a relatively simple method, there is a method in which fish is put into a sorting tank from an inlet and sorted by a plurality of grid sorters, but when the sorted fish descend, There was a problem of clogging with the pier.
[0003]
[Problems to be solved by the invention]
An object of the present invention is to provide a small and lightweight fish sorting apparatus that is simple in structure, has no clogging of fish, and is inexpensive and labor-saving.
[0004]
[Means for Solving the Problems]
The present invention is a fish sorting apparatus including a separator filter and a container for storing fish separated into large and small via the separator filter, wherein the separator filter has an interval suitable for the size of the fish to be sorted. A plurality of longitudinal pipes parallel to the flow direction of the fish, a transverse pipe perpendicular to the longitudinal pipe, and an intermediate support pipe connecting the longitudinal pipe and the transverse pipe vertically. The pipe is formed by incliningly connecting the vertical pipe and the horizontal pipe in the vertical direction and parallel to the flow direction of the fish at an angle of 45 ° up and down, and connecting the vertical pipe and the horizontal pipe in the vertical direction. in this the direction of angle joint is mounted for tilting the rear and forward tilting, alternately relative to the direction of flow of the fish in each one the longitudinal pipe The features.

DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, the fish sorting apparatus according to the present invention includes a fish jetting apparatus (not shown), a separator box 1, a separator filter 2, and containers 3 and 4.
[0006]
The fish is ejected from the fish jetting device to the separator filter 2 and is selected according to the separator filter size. Fish larger than the separator filter size passes through the filter, passes through the chute, and is stored in the container 3. Fishes smaller than the separator filter size fall between the filter lattices and are accommodated in another container 4.
[0007]
FIG. 2 is a perspective view showing the separator filter 2 of the fish sorting apparatus of the present invention.
The separator filter 2 is made of a stainless steel pipe, and a plurality of longitudinal pipes 5 are arranged in a direction parallel to the fish supply direction, and the width thereof can be changed according to the size of the fish. . Such a longitudinal pipe 5 is fixed to a transverse pipe 6 via intermediate support pipes 7 and 8.
[0008]
The longitudinal pipe 5, the transverse pipe 6 and the intermediate support pipes 7 and 8 are joined by welding, but the intermediate support pipes 7 and 8 connecting the longitudinal pipe 5 and the transverse pipe 6 are as shown in FIG. The horizontal pipe is connected to the horizontal pipe at an angle of 45 °, and is attached so that the directions are alternately reversed. By doing in this way, it can prevent that the fish which falls from a separator filter part is blocked.
[0009]
Even if the intermediate support pipes 7 and 8 are attached at right angles to the longitudinal pipe or attached at a certain angle, if they are attached in the same direction, the falling fish will be in this part. Often clogged.
[0010]
【The invention's effect】
The fish sorting device according to the present invention is characterized by the fact that the clogging of fish does not occur at the time of sorting due to the devised structure of the separator filter 2, but the structure is simpler than that, By adopting the natural flow action due to gravity, the configuration of the drive unit such as the vibration device of the filter unit is unnecessary, so that maintenance of this part is unnecessary, and it is compact and space-saving, lightweight, low There is also an advantage of price.
In addition, because it is small and lightweight, there is a merit that it can be mounted on a small fishing boat, but because there is a feature that clogging does not occur, regardless of small fishing boat, for example, various fishing boats such as large and medium fishing boats, It can also be used to select fish after landing on land.

Claims (1)

A fish sorting apparatus including a separator filter and a container for storing fish separated into large and small via the separator filter,
The separator filter includes a plurality of longitudinal pipes parallel to the flow direction of the fish at intervals suitable for the size of the fish to be selected, a transverse pipe perpendicular to the longitudinal pipe, and the longitudinal pipe and the transverse pipe. The intermediate support pipe is connected to the vertical pipe and the horizontal pipe at an angle of 45 ° up and down in the vertical direction and parallel to the flow direction of the fish, Moreover, the vertical pipe and the horizontal pipe are attached so that the direction in which the vertical pipe and the horizontal pipe are inclined in the vertical direction is alternately inclined forward and backward with respect to the flow direction of the fish for each vertical pipe. A fish sorting apparatus characterized by that.
