Description

[Detailed Description of the Invention] The present invention relates to an improvement of a seaweed collecting machine, and its purpose is to efficiently collect seaweed leaf pieces attached to seaweed nets laid in the sea.

Conventional technology As a method for collecting seaweed leaf pieces attached to a seaweed net, the seaweed net is passed over a seaweed net guide installed on a ship, and the seaweed leaf pieces hanging from the seaweed net are collected by an internal rotary blade. There is a known seaweed collecting machine that collects seaweed by cutting it, but since the collecting direction is fixed in this method, the direction of the ship is changed every time it moves to an adjacent seaweed net stretched in parallel, as shown in Figure 5. This has the disadvantage that it is not only inefficient, but also extremely troublesome to maneuver the ship to change direction.

Structure of the invention The present invention is an attempt to improve such defects, and its gist is that a pair of rotary blades that rotate outward from each other are installed on both sides of the upper part of the seaweed net guide. be.

To explain the embodiment of the present invention with reference to the drawings, a seaweed net guide body 2 installed on a collection boat 1 has a substantially trapezoidal support frame 3, 3 and a parallel parallel structure stretched on both sides of the upper part between the support frames 3, 3. It is composed of guide rods 4, 4, . is provided with a pair of rotary blade bodies 7, 7 that rotate outwardly relative to each other.

Therefore, it is preferable that the rotary blades 8 of the rotary blade bodies 7, 7 are formed in a twisted shape toward the rotation axis 9 thereof, and the adjustment plates 6, 6 are respectively movable by a length protruding outward. By adjusting the length, the length of the seaweed leaf pieces to be collected can be adjusted.

Note that 10 in the figure is a support plate for the rotating shaft 9.

Since the embodiment of the present invention is constructed as described above, when the seaweed net A is taken into the collection vessel 1 from the left side of the seaweed net guide 2, the rotary blade 7 on the left side
The rotary blade 8 mainly cuts and collects the pieces of seaweed hanging down from the seaweed net A into the guide rods 4, 4, and the remaining pieces of seaweed are removed by the rotary blade 7 on the right side. When the seaweed net A is taken into the collection vessel 1 from the right side of the seaweed net guide 2, the rotary blade 8 of the rotary blade body 7 on the right side mainly cuts and removes the seaweed leaves, and the remaining seaweed leaves are removed. The sample is collected using the rotary blade 7 on the left side.

Effects of the invention This invention installs a pair of rotating blades that rotate outward from each other on both the left and right sides of the seaweed net guide, and takes the seaweed net into the collection vessel from either the left or right side to cut and collect seaweed leaf pieces. Therefore, when collecting seaweed leaf pieces from seaweed nets stretched close to each other in parallel, the collection vessel can be moved to the underside of the adjacent seaweed net without changing the direction of the vessel each time. The seaweed net can be immediately taken in from the opposite side to collect the seaweed, and the rotating blade on the opposite side of the seaweed net collects uncut seaweed leaf pieces, and the cutting resistance at this time is the same as that of the seaweed net. It has the excellent features and practicality of reducing the pulling force of time, eliminating the need for the troublesome maneuvering of conventional ships, and allowing the collection work to be carried out efficiently, quickly and easily.
