Abstract

<P>PROBLEM TO BE SOLVED: To provide a suspended matter scraping apparatus which has high durability and efficiently scrapes suspended matters. <P>SOLUTION: A vertical axis 22 for supporting a cylindrical member 35 is disposed coaxially on the moving line of a moving member 57 which moves coaxially with the cylindrical member 35 within the cylindrical member 35. Thereby, an excessive bending moment is not applied to the cylindrical member 35 or the moving member 57 when the moving member 57 moves, and the cylindrical member 35, the moving member 57, etc., are not bent even in the case of a long-range operation. A gap between the scraping plates can be made small, as compared with a conventional case of installing the scraping plates in members disposed by being spaced to each other, by installing a first scraping plate 37 in the cylindrical member 35 and by installing a second scraping plate 67 in the moving member 57 moving within the cylindrical member 35. Consequently, the leakage of the suspended matter from the gap betweens the scraping plates is suppressed when the suspended matter is scraped. <P>COPYRIGHT: (C)2003,JPO

At this time, since the rotary shaft 22 for supporting the tubular member 35 is positioned coaxially with the moving line of the moving member 57, the tubular member 35 and the moving member 57 are moved when the moving member 57 is moved. An extra bending moment is not applied, and bending of the scratching arm 31 does not occur even if the operation is continued for a long time.

The first scraping plate 37 is attached to the tubular member 35,
The moving member 5 in which the second scraping plate 67 moves in the tubular member 35.
Since the gap between the scraping plates is narrower than that when the scraping plates are respectively installed on the members (main arm and sub arm) which are installed in No. 7 and are spaced apart from each other as in the related art, floating matters are prevented. It is difficult for the suspended matter to escape from the gap between the first scraping plate 37 and the second scraping plate 67 when scraping. Further, since the main arm and the like are not required, the scraping arm 31 (corresponding to the conventional main arm, sub arm and tubular member) is lighter than the conventional one.
The scratching arm 31 is smoothly guided to reduce the power required for rotation, and the number of parts is reduced to achieve cost reduction.

According to the floating material scraping apparatus of the present invention,
Since the vertical axis that supports the tubular member is arranged coaxially with the moving line of the moving member that moves in the tubular member coaxially with the tubular member, the tubular member and the moving member move when the moving member moves. No excessive bending moment is applied to the member, and bending of the tubular member or the moving member does not occur even if the member is operated for a long time.
