BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described.
[0014]
The present invention is an improvement of Japanese Patent Application No. 2002-175350. After the work is completed, the washing water is reversely supplied into the sorting casing to quickly and neatly clean the sealed sorting casing of the laver stirring / separation chamber. Backwashing method. At this time, if the gap is too small, internal pressure is generated and cleaning cannot be performed. Therefore, the gap needs to be enlarged to about 2 mm. According to the present invention, when the knob (handle) is loosened about two turns, the lower end of the knob of the knob moves up, and the ball moves (moves in the anti-radiation direction) to the tapered portion provided at the lower end of the knob, thereby forming a pair of cones. The seats are close and the gap widens by about 2 mm. Utilizing this enlarged gap, the cleaning water is reversely injected. Cleaning (backwashing) is performed through this back injection, and foreign matter clogged in the gap or foreign matter in the vicinity thereof is collected, discharged through the opened foreign matter discharge port together with the remaining seaweed, and also in the seaweed stirring / separation chamber. Clean dirt. After the discharge and cleaning (hereinafter referred to as discharge), by reversely operating the knob, the balls sequentially move radially from the tapered portion to the true circular shaft portion, and separate the pair of conical seats. The gap shrinks through this separation, and the gap can be reliably returned to the original position (a predetermined gap is secured). These gaps can be surely expanded and contracted, and there is a benefit that this operation can be performed safely and quickly.

The gap adjusting nut 24 is in contact with the upper end 81 of the rotating shaft 8 (via a conical seat described later). The gap 6 expands and contracts when the positioning ring 21 is screwed and unscrewed. The structure in which the gap adjusting nut 24 is externally fitted to the upper end 81 of the fixed rotating shaft 8 is ideal because it can contribute to downsizing of the shaft structure. In the drawing, reference numerals 25 and 26 denote conical seats provided at intervals in a chamber 20a formed between the upper end 81 of the rotary shaft 8 and the lower side 90a of the cap of the rotary hollow shaft 9, and have tapered surfaces 25a. , 26a hold a ball 27. Therefore, the vertical movement of the rotary hollow shaft 9 is determined by the movement of the ball 27 on the tapered surfaces 25a and 26a. Then, since the ball 27 moves on the tapered surfaces 25a and 26a, fine adjustment can be performed by the screw engagement adjusting mechanism. In addition, by utilizing this fine adjustment, it can be applied to various devices other than the raw laver separation device. Reference numeral 28 denotes a knob which is screwed to the screw 82 of the rotating shaft 8 and is provided through a cap portion of the gap adjusting nut 24. A tapered portion 28b is formed at a lower end 28a of the shaft portion of the knob 28. The tapered portion 28b regulates the movement of the ball 27. For example, FIG. 4 shows a state in which the ball 27 has spread between the conical seats 25 and 26 and the gap 6 has contracted (small), and FIG. Are narrowed, and the state in which the gap 6 is enlarged (large) is shown. Reference numeral 28c denotes a shaft of the knob 28. By rotating the knob 28, the gap 6 can be finely adjusted, so that a woman can easily operate the gap. In the figure, reference numeral 29 denotes a spring (elastic body) provided between the knob 28 and the gap adjusting nut 24, which constantly pushes the gap adjusting nut 24 downward. Reference numeral 30 denotes a pin inserted into the hole of the gap adjusting nut 24 and the hole of the positioning ring 21. The pin 30 is selectively inserted into a plurality of provided holes to position the gap adjusting nut 24 and secure the dimension of the gap 6. . Note that the means 20 is merely an example, and other configurations having the same function are also included in the scope of the present invention. Therefore, since the gap 6 can be finely adjusted, the apparatus can naturally be used as a washing means in the processing of raw laver. The second gap adjusting means includes a ball 25 provided between the conical seats 25 and 26, a taper portion 28b of the knob 28, or a spring provided in a space formed by the knob 28 and the gap adjusting nut 24. 29. In the figure, reference numeral 40 denotes a stop plate for stopping the conical seats 25, 26.
