【発明の詳細な説明】
本発明は下水路、用水取水路等に設ける水路用除塵の篩
渣掻揚装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sieve sludge scraping device for removing dust from waterways installed in sewage channels, irrigation water intake channels, and the like.
従来より使用されている除塵機を大別すると、流路を横
断する如く設けた除塵格子に対する篩渣掻揚装置の位置
関係により、夫々表掻式、中種式および裏掻式の三種に
分類される。Conventionally used dust removers can be roughly divided into three types: surface scraping type, medium scraping type, and back scraping type, depending on the positional relationship of the sieve residue scraping device to the dust removal grid installed across the flow path. be done.
このうち裏掻式と称するものは篩渣掻揚装置が除塵格子
の下流側に設けられるため、流路中の塵芥の掻揚に好都
合である。Among these, the so-called back scraping type has a sieve residue scraping device installed on the downstream side of the dust removal grid, and is therefore convenient for scraping up dust in the flow path.
しかしながら、塵芥中には硬軟、形状等種々雑多な性状
のものが混在し前記掻揚装置によって掻揚げた後におい
ても容易に離脱せず、その排出が極めて困難な場合があ
る。However, there are cases in which the garbage has various properties such as hardness, softness, shape, etc., and it does not come off easily even after being scraped up by the scraping device, making it extremely difficult to discharge it.
このため掻揚装置を構成するレーキに摺接するワイパー
装置を付設するのであるが、通常振子型の自重レバ一式
のものが多い。For this reason, a wiper device that slides into contact with the rake that constitutes the raking device is attached, but it is usually a pendulum-type self-weight lever set.
このような振子型自重レバ一式のものは、レーキの移動
によってレーキの一端がワイパー掻刃の一端に衝突し、
レーキと摺接するワイパー持上によって、レーキ上をワ
イパー掻刃部が篩渣の落下方向に滑るものである。In such a pendulum-type self-weight lever set, one end of the rake collides with one end of the wiper scraper blade as the rake moves.
By lifting the wiper in sliding contact with the rake, the wiper scraper blade slides on the rake in the direction in which the sieve residue falls.
その掻取接触軌跡は自在にとれ、また機構が簡単である
ため、安価でスペースも少くてすむので゛多く採用され
ている。The scraping contact trajectory can be set freely, and the mechanism is simple, so it is inexpensive and requires less space, so it is widely used.
しかしながら、レーキ上の篩渣の硬軟、形状、密着度等
により、ワイパー先端が常時レーキ上面と接触せず、篩
渣に乗り上７け゛ることが多い。However, due to the hardness, shape, degree of adhesion, etc. of the sieve residue on the rake, the wiper tip does not always come into contact with the upper surface of the rake and often rides on the sieve residue.
また、乗り上げた物の大きさによりその層分は掻残しが
出来ることが多い。Also, depending on the size of the object that has climbed on top of it, the layer is often left unscraped.
更にワイパー掻刃部−をレーキ上で滑らせる作用を利用
しているため、レーキに篩渣を押し付けることにもなり
、フラゾｒ）な布、紙、ビニール等やひも状の物がから
み合ったり、レーキに巻き付いた篩渣は極めてワイピン
グし難い状態となる欠点があった。Furthermore, since the wiper scraping blade is made to slide on the rake, the sieve residue is pressed against the rake, which prevents furazor cloth, paper, vinyl, etc., and string-like objects from becoming entangled. However, the sieve residue wrapped around the rake is extremely difficult to wipe.
