Description

[Detailed description of the invention] Purpose of the invention The purpose of the invention is to improve the collection efficiency of a water suction type sea cane collector.

Conventional technology This type of conventional water suction type seaweed collecting machine has a fixed blade and a rotary blade superimposed at the bottom of the main body, and uses a suction pipe connected to a pump installed at the top of the main body to collect seaweed leaves together with seawater. Currently, the suction is cut and sampled using the rotating action of the suction rotary blade and sent to the suction pipe, but the suction force is strong right below the suction pipe, and the suction action is not uniform over the entire surface of the sampling hole in the main body, and the rotation of the rotary blade The centrifugal force caused by this method inhibits the suction action of the sea cane leaves into the suction pipe, resulting in a significant drop in collection efficiency.

In order to improve this kind of defect, it has been considered to provide a disc-shaped rectifying plate in the center above the fixed blade, but since the rectifying plate is only in the center and is away from the fixed blade, it is still not possible to solve the problem described above. The reality is that defects cannot be reliably prevented.

Composition of the invention The present invention is an attempt to improve the above-mentioned deficiencies of the conventional system by using an extremely simple structure.A rectifying disk is fixed in the main body of the sampling machine, which has a suction pipe at the top, so as to divide it into upper and lower halves. The gist is that a blade portion is formed on the edge of the through hole bored in the rectifying disk, and a rotary blade is provided at the lower part of the rectifying disk so as to come into sliding contact with the blade portion.

Embodiment An embodiment of the present invention will be described with reference to the drawings. A cylindrical sampling machine main body 3 has a suction pipe 1 connected to a pump on the upper side and a sampling hole 2 on the lower side.
At its center is a hydraulic motor or other suitable drive source 4.
A rotating shaft 5 driven by is supported, and a radial rotating blade 6 is fixed to the lower end of the rotating shaft 5 so as to be located inside the sampling hole 2.

Further, a rectifying disk 7 is fixed to the collector body 3 inside the rotary blade 6 so as to divide it into upper and lower parts, and an appropriate number of through holes 8 are bored in the rectifying disk 7. A blade portion 9 protruding from the edge of the mouth is configured to come into sliding contact with the rotary blade 6.

Since the embodiment of the present invention is constructed as described above, when the rotary blade 6 is rotated at the same time as the pump suctions seawater through the suction pipe 1, the seaweed leaf pieces sucked into the collection machine main body 3 together with the seawater are It is sucked into the sampling machine main body 3 through the through hole 8 of the rectifying disk 7 and collected by the cutting action of the rotary blade 6 and the blade part 9, and then sent to the suction pipe 1 and collected.

However, in this case, the centrifugal force due to the rotating action of the rotary blade 6 is blocked by the rectifying disk 7, and the collecting machine main body 3
The sea cane leaves are cut smoothly by the through holes 8 with a high flow velocity, without directly propagating to the upper part of the water.
The suction collection action can be performed efficiently.

In the above embodiment, the rotary blade 6 is formed as a radial turning blade, but it may be formed as a normal perforated disc blade.

Effects of the invention The present invention fixes a rectifying disk inside the collecting machine body of this type of suction type sea cane harvesting machine so as to divide it into upper and lower halves, and forms a blade part on the edge of the opening of the through hole bored in the rectifying disc. Since the rotary blade is provided as a fixed blade and the rotary blade is provided in sliding contact with the lower side, the centrifugal force caused by the rotating action of the rotary blade is blocked by the rectifying disk and the suction effect from the through hole of the sea cane leaf is inhibited. In addition, the cutting action of the seaweed leaves can be carried out smoothly and reliably by the fast-flowing through-hole edge blade and the rotating blade, and the seaweed leaves can be efficiently collected by suction, increasing the efficiency of the collection work. Moreover, since the rectifying disk itself has the through-hole edge formed into a fixed blade, its structure is extremely simple and its weight is light, which has excellent features and practicality.
