Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a seaweed collecting machine that collects seaweed leaf pieces attached to a seaweed net.

[Conventional technology]

As a method of collecting seaweed leaf pieces attached to a seaweed net, the seaweed net is pulled up from the sea, and the net is hoisted onto a seaweed collecting machine installed on a ship, and the seaweed leaf pieces hanging from the seaweed net are placed approximately in the axial direction. It is known to cut and collect with a rotary blade.

[Problem that the idea aims to solve]

However, in the conventional method, a bar-shaped guide frame is fixed to the outside of the rotary blade to prevent the seaweed net from being cut by the rotating blade and to regulate the length of the remaining seaweed leaves. There is a defect in which hanging seaweed leaves cannot be cut and collected by the rotary blade because they are caught in the guide frame and passed through the upper part of the rotary blade. In view of these current circumstances, the present invention has been developed to provide a seaweed harvesting machine that can reliably collect seaweed leaf pieces that have grown on seaweed nets by forming a ring-shaped guide to prevent the seaweed net from being cut and rotating together with the rotary blade. The purpose is to provide

[Means to solve the problem]

In order to achieve the above object, the present invention has a rotary blade installed between a pair of rotary blade support disks fixed to a rotary shaft, and annular guide frames are fitted on the outside of the rotary blade at appropriate intervals around the rotary shaft. In addition, the inner edge of the annular guide frame is fixed to the rotary blade. One or more of the rotary blades are installed at equal intervals on the circumference between the opposing rotary blade support disks. Accordingly, the present invention uses the structure described above as a minimum unit collecting body, and connects an appropriate number of rotary blade support disks of this collecting body to form a seaweed collecting machine.

[Effect]

In this invention, by rotating the rotating shaft, the rotary blade and the annular guide frame are simultaneously rotated, and the seaweed net is pulled up onto the annular guide frame, and the seaweed leaf pieces that are hanging down on the net are entangled with the annular guide frame. It is used to cut and collect with a rotating blade without cutting.

【Example】

An embodiment of the present invention will be described with reference to the drawings. One or more rotary blades 3 are mounted between a pair of rotary blade support discs 2, 2 via a mounting plate 1' on a rotary shaft 1 driven by an arbitrary power. An appropriate number of collecting bodies 4 which are installed and fixed in a slightly twisted shape are fixed in a connected state, and annular guide frames 5 are provided at appropriate intervals on the rotary blade 3 between the rotary blade support disks 2, 2 of each of the collecting bodies 4. , 5 . Therefore, the diameter of the hole in the annular portion of the annular guide frame 5 is made larger than the diameter of the rotary blade support disk 2 so that the annular guide frame 5 can be fitted onto the outside of the rotary blade 3 from one side of the collection object 4. The structure is such that the number of annular guide frames 5 can be increased or decreased to adjust the interval between them, and annular guide frames 5 of different widths (radial widths) of the annular portion can be used interchangeably. Further, the rotary blade support disk 2 is provided with a circular arc-shaped long hole 8, and by shifting the overlapping position of the circular arc-shaped long hole 8 of the adjacent sampling object 4 and fixing it with a tightening tool 9, the adjacent sampling object 4 can be fixed. The rotary blades 3 are formed so that they can be connected and fixed by adjusting their mutual positions. Therefore, when the rotating shaft 1 is rotated while lifting the seaweed net onto the collecting bodies 4, 4..., the seaweed leaf pieces B attached to the seaweed net A are suspended from between the annular guide frame 5 and the rotary blade 3 section. through the annular guide frame 5 by the rotary blade 3.
It is cut and collected leaving the width of the annular part intact. According to experiments, the torsion degree of the rotary blade 3 is 30mm for a specimen with a length of 350mm.
The width of the annular portion of the annular guide frame 5 is preferably approximately 30 mm for long cutting and 15 mm for short cutting.

[Effect of the idea]

The present invention prevents the seaweed net from being cut by the rotating blade, and also controls the length of the remaining seaweed leaves by fixing the annular guide frame to the rotating blade at the inner edge of the annular part so that the frame rotates together with the rotating blade. As a result, it is possible to prevent the seaweed net from being cut and to control the uncut length of the seaweed leaf pieces, while efficiently cutting and collecting the seaweed leaf pieces in a hanging state without tangling them, increasing the collection efficiency of seaweed leaf pieces. In addition, the length of uncut seaweed leaves can be easily adjusted by replacing annular frames with different annular widths, and the interval between the annular guide frames can also be adjusted to ensure accuracy according to the amount of nori leaves that have settled. This can prevent the seaweed net from being cut.
