Description

[Detailed description of the invention] The present invention relates to an improvement of a suction type seaweed collector.

Conventionally, a suction-type seaweed collecting machine is known, in which a collecting hole is drilled in the lower part of the collecting machine, the seaweed leaf pieces are sucked into the collecting machine together with seawater, and the pieces are cut and collected using a cutting device consisting of a rotating cylindrical blade and a fixed blade. However, with this method, when seawater pollution is severe as in recent times, the seaweed leaves are collected with dirt still attached to them, making washing them extremely troublesome after collection, and if the seaweed net is loose, it is sucked into the rotating cylinder. There is a defect that is cut by the blade.

The present invention is an attempt to improve these defects by providing a pair of sampling holes in parallel at the bottom of a sampling machine connected to a suction and flow pipe, and a rotating cylindrical blade and a fixed blade inside the sampling hole. The gist of the invention is to provide cutting devices each consisting of the following.

To explain an embodiment of the present invention with reference to the drawings, a pair of sampling holes 4, 4 having a crosspiece frame 3 are provided in parallel at the bottom of a sampling machine 2, which has a suction and flow pipe 1 connected to its upper part. Cutting devices 7, 7 each consisting of a rotating cylindrical blade 5 and a fixed blade 6 are provided inside the sampling holes 4, 4, and the rotating cylindrical blades 5, 5 usually rotate in opposite directions. However, they can also be rotated in the same direction, and the fixed blades 6, 6 are provided on one side of the sampling holes 4, 4 and inside the rotating cylindrical blades 5, 5.

The suction/distribution pipe 1 is connected to a suction pump on board the ship, and although it is not shown on the collection machine 2, it is also possible to provide a float like the known collection machine, and furthermore, the Cylindrical blade 5
The rotating means is also optional. Note that 8 in the figure is the fixed blade 6.
The fixed shaft 9 is a seaweed net.

Since the embodiment of the present invention is constructed as described above, the collecting machine 2 is moved in sliding contact with the seaweed net 9 while sucking seawater from the collecting holes 4, 4 through the suction and flow pipe 1, and at the same time the rotating cylinder When the blades 5, 5 are rotated, the seaweed leaf pieces that are sucked into the collecting machine 2 along with the seawater are cut by a cutting device 7 consisting of a rotating cylindrical blade 5 and a fixed blade 6, and are sent from the suction/distribution pipe 1 into the ship. In this case, the seaweed leaf pieces cut and collected from each collection hole 4, 4 into the collection machine 2 are transported into the collection machine 2 by an agitating water flow generated by rotating cylindrical blades 5, 5. The seaweed net 9 between the collection holes 4 and 4 is pulled together by the suction action of each so that the seaweed net 9 does not loosen.
This prevents the blade from being cut by the rotating cylindrical blades 5, 5.

In the present invention, the seaweed leaf pieces collected inside the collection machine are stirred and washed by a mixing flow caused by a pair of rotating cylindrical blades and the rotating cylindrical blades, and then collected on board a ship using a suction and flow pipe. As a result, dirt adhering to the seaweed leaf pieces can be efficiently and quickly removed, washing after collection is facilitated, and high-quality seaweed can be produced.

In addition, during collection, the collecting machine uses a pair of collecting holes to suck and pull the seaweed net while collecting, so even if the seaweed net is loose, it does not cut or damage the seaweed net, making it an excellent feature that allows for efficient collection work. have
