つ確実に可能にしたものである。[Detailed Description of the Invention] The present invention relates to a rake scraping-type dust remover installed in intake channels, settling basin channels, etc., in which the rake is attached to a multi-stage telescopic boom that extends and moves up and down by winding and unwinding a wire rope. By operating the rope, the rake is raised and lowered and the rake is opened and closed relative to the bar screen, and when the rake is lowered, the rake is placed in a downward position, and the rake can be forced into the water easily and reliably.
以下その詳細を図面の実施例について説明する。The details will be explained below with reference to the embodiments shown in the drawings.

る。The rake side lobe 8' has a fixed sheave 14. 15. 16
The movable sheave 1 is guided to the drum 7.5 through the drum 7.5, and its middle part is connected to a traction device 17 such as a hydraulic or electric cylinder, and the movable sheave 1 is provided at the upper end of the piston 17b of the cylinder 17a.
When 8 is lowered by a certain distance, the loaf is tensed and the rake is closed, and the rake 2 is oriented to engage the bar screen 1.
レーキ2による掻揚げはこのレーキ閉の状態で行われる
。Raking with the rake 2 is performed with the rake closed.
次に可動シーブ18によるロープの緊張を解除すると第
2図に示すようにレーキ2は下向きとなってレーキ開と
なる。Next, when the tension on the rope by the movable sheave 18 is released, the rake 2 is directed downward and the rake is opened as shown in FIG.
レーキ2の下降動作はとのレーキ開の状態で行われる。The lowering operation of the rake 2 is performed with the rake 2 in the open state.

3a are housed in sequence, and the uppermost part 3c is supported on a fixed base 6 so as to be able to swing back and forth about a pivot 19, and when a special need for lowering the rake is required, a swinging mechanism 20 such as a hydraulic or electric cylinder is used. It is configured so that it can be pushed by.
従来のローブ式除塵機においてはレーキ下降動作をレー
キの自重で行う方式が一般的であった為に、バースクリ
ーン前面の水面上に浮力の大きな粗大ゴミが粒着したよ
うな場合にはレーキがこの粗大ゴミに乗り上げて水中へ
の下降を妨げ除塵機としての機能を発揮できないことが
往々にあったものである。Conventional lobe-type dust removers generally use the rake's own weight to lower the rake, so if large particles of highly buoyant debris land on the water surface in front of the bar screen, the rake Often, the dust remover would run aground on the bulky debris and prevent it from descending into the water, making it unable to perform its function as a dust remover.
この為レーキの自重を必要以上に重くする方法が考えら
れるのであるが、駆動装置の容量が大となり、装置も大
型化するので実用的でない欠点がある。For this reason, a method of increasing the weight of the rake more than necessary has been considered, but this method has the drawback that the capacity of the drive device becomes large and the device also becomes large, making it impractical.
又レーキ下降に強制力をもたせる為に油圧シリンダーを
用いて油圧シリンダーの先端にレーキを取付ける油圧方
式の除塵機も開発されているが、油圧機器のコスト嵩や
、オイル洩れ故障時のメンテナンスの煩雑さ等に難点が
あって未だに実用の域に達していないのが現状である。In addition, a hydraulic type dust remover has been developed that uses a hydraulic cylinder and attaches the rake to the tip of the hydraulic cylinder in order to force the rake to descend, but this increases the cost of the hydraulic equipment and requires complicated maintenance in the event of an oil leakage failure. At present, it has some drawbacks and has not yet reached the level of practical use.
本発明はこのような従来の欠点を改良したもので、上述

なこと力;なく、円滑に作業ができる。The present invention improves on such conventional drawbacks, and as described above, one end of the lobe wrapped around the lifting drum is attached to the rake at the lowest end of the telescopic boom, and the other end is attached to the top and bottom of each telescopic boom. They are fixed to the upper end of the lowest stage telescopic boom through the ropes, and the telescopic boom is forcibly extended and lowered by hoisting the boom side rope, and a part of the rake side rope is connected to the traction device for lifting. The telescopic boom is reliably raised and lowered by operating the lobe by rotating the drum forward and backward, and the rake is pulled into the water from below, making forcible entry into the water powerful and reliable, and rake over large debris. The work can be done smoothly without any force that might run on the machine and prevent it from descending.
又レーキ側ロープの一部を牽引装置によって緊張又は弛
緩させることによってレーキの開閉を昇降動作中に行な
うことができ、構造も簡単で安価に実施できる等の効果
を有する。Furthermore, by tensioning or relaxing a part of the rake side rope by the traction device, the rake can be opened and closed during the lifting and lowering operations, and the structure is simple and can be implemented at low cost.
