次に、以上のように構成される岩盤清掃装置1の使用方法について説明する。
岩盤清掃装置1は、取り付ける走行車両の取り付け部分の形状に合わせて製作した固定部2を用いて走行車両に固定する。
例えば、図1に示すように、走行車両としてバックホウを用いる場合は、そのアーム19先端部に取り付ける。
Next, the usage method of the bedrock cleaning apparatus 1 comprised as mentioned above is demonstrated.
The bedrock cleaning device 1 is fixed to the traveling vehicle by using a fixing portion 2 manufactured in accordance with the shape of the mounting portion of the traveling vehicle to be attached.
For example, as shown in FIG. 1, when using a backhoe as a traveling vehicle, it attaches to the arm 19 front-end | tip part.

岩盤清掃装置1を取り付けたバックホウを、清掃する範囲の前端付近まで進め、清掃を開始する地点へアーム19を伸ばす。
このとき、図1に示すようにスイングアーム4は、緩衝手段7によってその揺動範囲が制限されているので、斜め下方に懸垂した状態で係止される。
この状態からアーム19を下げ、岩盤清掃装置1の掻き取り部材9が岩盤表面に圧接する高さまで下げたら、モータ12を駆動し掻き取り部材9を回転させる。
この回転方向は、砂礫をバックホウ本体側にかき寄せる方向であり、例えば図1中では、反時計方向とする。
モータ12の回転数は、コントローラ13により適切な回転数に調節する。
モータ12の駆動力は貫通軸5に伝達され、図3に示すように、これに接続した駆動スプロケット14を駆動する。
さらに、ローラチェーン16により従動スプロケット15に駆動力を伝達することで、回転部8が回転し、掻き取り部材9が回転する。
The backhoe with the bedrock cleaning device 1 attached is advanced to the vicinity of the front end of the area to be cleaned, and the arm 19 is extended to the point where cleaning is started.
At this time, as shown in FIG. 1, since the swinging range of the swing arm 4 is limited by the buffer means 7, the swing arm 4 is locked in a state of being suspended obliquely downward.
When the arm 19 is lowered from this state and lowered to a height at which the scraping member 9 of the rock cleaning device 1 is pressed against the rock surface, the motor 12 is driven to rotate the scraping member 9.
This rotation direction is a direction in which sand and gravel are scraped toward the backhoe body side, and is, for example, counterclockwise in FIG.
The rotation speed of the motor 12 is adjusted to an appropriate rotation speed by the controller 13.
The driving force of the motor 12 is transmitted to the penetrating shaft 5 and drives a driving sprocket 14 connected thereto as shown in FIG.
Further, the driving force is transmitted to the driven sprocket 15 by the roller chain 16, whereby the rotating portion 8 rotates and the scraping member 9 rotates.

岩盤表面に対する岩盤清掃機1の高さを保ったまま、アーム19を操作して岩盤清掃装置1をバックホウの本体側に移動し、岩盤表面の砂礫をかき集める。
バックホウ本体側まで岩盤清掃機1を移動させたら、バックホウを左右に岩盤清掃装置1の分だけ旋回し、再びアーム19を伸ばし清掃を行う。
バックホウ前方のアーム19が届く範囲の清掃が完了したら、バックホウを後方に移動し上記の操作を繰り返す。
かき集めた砂礫は、他のバックホウやバキューム装置によって除去する。
While maintaining the height of the rock cleaning machine 1 with respect to the rock surface, the arm 19 is operated to move the rock cleaning device 1 to the backhoe body side, and the gravel on the rock surface is collected.
When the bedrock cleaner 1 is moved to the backhoe body side, the backhoe is swung to the left and right by the amount of the bedrock cleaning device 1, and the arm 19 is extended again for cleaning.
When the cleaning of the range where the arm 19 in front of the backhoe reaches is completed, the backhoe is moved backward and the above operation is repeated.
The collected gravel is removed by another backhoe or vacuum device.

清掃中に岩盤清掃装置1が当初の高さより下がった場合、スイングアーム4の上部に取り付けられた緩衝手段7が縮退し、岩盤表面と掻き取り部材9の高さを適切な高さに保つ。
また、岩盤の表面に凹凸がある場合は、その部分のスイングアーム4が上下に揺動するので、掻き取り部材9が岩盤表面から離れることはない。
掻き取り部材9は、岩盤の状態に合わせて適宜最適な形状、材質のものに取り替える。
また、例えば、ゴム板と鉄板を交互に取り付けるなど、複数の種類の掻き取り部材9を同時に装着してもよい。
本発明を適用した岩盤清掃装置1では、掻き取り部材9を回転部8にボルトで取り付ける構造としたので、上記の交換作業が簡単に行える。
When the rock mass cleaning device 1 is lowered from the initial height during cleaning, the buffer means 7 attached to the upper part of the swing arm 4 is retracted, and the height of the rock mass surface and the scraping member 9 is maintained at an appropriate height.
Further, if the rock surface has irregularities, the swing arm 4 in that portion swings up and down, so that the scraping member 9 does not leave the rock surface.
The scraping member 9 is appropriately replaced with one having an optimal shape and material according to the condition of the rock.
Further, for example, a plurality of types of scraping members 9 may be mounted simultaneously, such as attaching rubber plates and iron plates alternately.
The rock cleaning device 1 to which the present invention is applied has a structure in which the scraping member 9 is attached to the rotating portion 8 with a bolt, so that the above replacement operation can be easily performed.

なお、以上の実施の形態においては、スイングアーム4の本数を4本、1つの回転部8に取り付ける掻き取り部材9の枚数を4枚としたが、本発明はこれに限定されるものではない。
また、モータ12への負担を軽減するために、図4に示したように掻き取り部材9を配置したが、この目的のためには、必ずしも全体を螺旋状に配置する必要はなく、同時に岩盤表面に当接する掻き取り部材9の枚数が少なくなるように配置すれば良い。
さらに、掻き取り部材9の形状や材質も、上記で示した以外の形状、材質でも良く、その他、具体的な細部構造等についても適宜に変更可能であることは勿論である。
In the above embodiment, the number of swing arms 4 is four, and the number of scraping members 9 attached to one rotating portion 8 is four. However, the present invention is not limited to this. .
Further, in order to reduce the burden on the motor 12, the scraping member 9 is arranged as shown in FIG. 4, but for this purpose, it is not always necessary to arrange the whole in a spiral shape, and at the same time, the bedrock What is necessary is just to arrange | position so that the number of the scraping members 9 contact | abutted on the surface may decrease.
Furthermore, the shape and material of the scraping member 9 may be other shapes and materials than those described above, and it is needless to say that other specific detailed structures can be appropriately changed.
