Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for sorting shrimp, etc. caught by bottom trawling, and more specifically, it relates to a device for sorting shrimp, etc. caught in bottom trawling, and more specifically, shrimp and various kinds of fish caught in bottom trawling nets. The present invention also relates to a shrimp sorting device configured to sort shrimp into flat fish and long fish from garbage mixed in a net, and to discharge the garbage.

[Prior art and interlayer points] In recent years, in the commonly practiced bottom trawl fishing, due to the increase in the size of vessels, increase in engine output, and development of operating methods, etc.
Despite the significant improvement in fishing capacity, the selection of the catch on board the ship is still carried out manually by workers. In other words, the reality is that fish caught with bottom trawl nets are piled up on the deck, and workers surround the pile, sorting and sorting the piled fish by type and size, cleaning them, and packing them into boxes. Naturally, such work is inefficient, and not only is it difficult to work in stormy weather, but the sorting work is always done in a bent-back position, making it very difficult to work for long periods of time.

The development of sorting machines has been progressing to solve these problems, but in addition to the wide variety of catches, in recent years a large amount of garbage has entered the nets along with the catch due to sea pollution, and high-quality catches have been It was difficult to sort shrimp, etc. with automated sorting machines because they get mixed in with the garbage.

[Means for Solving the Problems] In view of the problems involved, the present invention removes garbage in a sorter, simultaneously sorts and sorts shrimp, and further sorts and sorts flat fish and long fish. In order to automatically perform this, a large number of rollers are mounted parallel to each other with a gap through which the body of the shrimp can pass, and the axes of the rollers are installed in the gap with a gap that allows the length of the shrimp to pass through. A drive mechanism for rotating the rollers of Z in the same direction is provided, and the drive mechanism rotates the disks in the same direction in conjunction with the drive mechanism. It is a sorting device for shrimp etc. that is equipped with a mechanism, and in history, a sorting device consisting of the roller and disk etc. is placed in an appropriate aquarium,
It is an object of the present invention to provide a sorting device for shrimp, etc., which is configured to operate in a state where the upper surface of the roller and the water surface are substantially the same.

[Example] Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

A gap 5 is provided between the two, through which the body of the shrimp in the catch can pass.

A disc 7 whose rotation direction is in the axial direction of the roller 2 is provided in the gap 5.5 between each of the rollers 2.2 with an interval C) through which the shrimp can pass in the longitudinal direction. 7... is attached to the shaft. The upper surface of the disc 7.7... is the roller 2
A plurality of projecting pieces 7a are provided on the circumferential surfaces of the discs 7, 7, . . . Incidentally, the space formed by the gap 5 between the rollers 2 and 2 and the space 0 provided between the discs 7 and 7 serves as a shrimp sorting opening.

Further, although not shown, if the width of the gap 5 between the rollers 2.2 can be adjusted, it will be more advantageous to sort shrimp and the like according to their size and type.

Each roller 2, 2... is driven by a drive mechanism 8 that rotates in the same direction, but the drive mechanism 8 is not limited and may be any drive mechanism normally used for this type of drive. .

In this embodiment, an electric motor 10 with a reduction gear installed on a pedestal 3 drives an intermediate shaft 11 which is also supported on the pedestal with a belt, and the intermediate shaft 11 drives the rollers 2, 2, . . .
are driven by cross-strapped belts 12, 12... to rotate the rollers 2, 2... in the same direction.

Although the disc drive mechanism 15 that drives the discs 7 in the same direction is not limited to this drive mechanism, in this embodiment, the first disc shaft is driven by a belt from the intermediate shaft 11, and the first disc drive mechanism 15 drives the discs 7 in the same direction. 2nd disk axis from the axis, and 3rd disk from the 2nd axis
axis. The 4th axis is driven by the 3rd axis, and the 5th disc axis is driven by the 4th axis so that they rotate in the same direction by a belt 16.

The sorting device 1 is disposed at the upper part of a water tank 20 having an appropriate depth, and is configured to operate when the go surface of the roller 2 and the water surface are in a gap. By rotating the formed disk 7 in water, the shrimp was directed downward into the space (shrimp sorting opening) formed by the gap 5 between the rollers 2.2 and the gap 6 provided between the disks 7.7. A water flow is generated, and the shrimp are drawn into the water below the roller 2 by the water flow.

[Function 1] Next, the function will be explained. The drive mechanism 8 is driven to rotate the rollers 2, 2, . . . in the direction of the arrow shown in FIG.

The disk drive mechanism 15 interlocked with the drive mechanism 8 is also activated at the same time to rotate the disks 7, 7, . . . in the direction of the arrow shown in FIG.

A sorting device consisting of 7... etc. is arranged in a suitable water tank 20, and is configured to operate in a state where the top surface of the rollers 2, 2... and the water surface are almost the same. Conventionally, fish caught with bottom trawling nets were piled up on the deck, and workers surrounded them to sort and sort the piled-up fish by fish type and size, which improved work efficiency. In addition, since the sorting work is done in a bent-back position, it is very difficult to work for long hours.Furthermore, the catch is diverse, and a large amount of garbage enters the net at the same time as the catch. It was said that it was difficult to sort the shrimp because it mixed in with the garbage, but in the present invention, while the shrimp are transferred together with the garbage by the rotation of the rollers 2, 2... Since the shrimp are drawn downward by the water flow from the sorting port, the shrimp sorting ability is greatly improved. At the same time, garbage is discharged from the discharging side I3 on the rollers 2, 2, 2, etc., and flat fish species such as Holi Rei are also sent to the discharging side B through the rollers 2, 2, 2, and eel, etc. Long fish species such as cutlassfish enter the upper part of the gap 5 and are sent to the side C by the rotation of the discs 7, 7, etc., so that a wide variety of catches are efficiently and automatically sorted. It has a truly remarkable effect f,=a.
