本考案は、掘削溝縁に盛り上がるトレンチャ−からの排
出土砂が再び溝底に落下するのを防止するための溝仕上
縁泥掻き分は装置の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for removing dirt from a trench finishing edge to prevent earth and sand discharged from a trencher from falling onto the trench bottom again.
一般にトレンチャ−からの排出土砂が再び溝底に落下す
るのを防止するため、種々の掘削土排除装置が提案され
ている。In general, various excavated soil removal devices have been proposed to prevent soil discharged from a trencher from falling back onto the trench bottom.
例えば、実開昭４９−４１７０６号公報記載の掘削土排
除装置にあっては、掘削パケットチェーンを三角形に張
架し、該パケットチェーンの掻き上げ側に掘削土の排除
装置を設は地表面に送り上げられる掘削上を溝の外側へ
自動的に排除するようにすることが提案されている。For example, in the excavated soil removal device described in Japanese Utility Model Application Publication No. 49-41706, an excavation packet chain is stretched in a triangular shape, and an excavated soil removal device is installed on the raking side of the packet chain. It has been proposed to automatically exclude the excavation being fed to the outside of the trench.
しかしながら、掘削パケットチェーンを使用する場合、
掘削パケットの戻り側において各パケットが溝縁の障害
物、凍土、玉石等を巻き込んでパケットを破損させたり
、連続パケットの回転を止めたり、ガイドローラから外
れたりする場合があり、作業の能率及び精度が充分に上
らない欠点がある。However, when using a drilling packet chain,
On the return side of the excavation packet, each packet may become entangled with obstacles on the trench edge, frozen soil, cobblestones, etc., damaging the packet, stopping the rotation of the continuous packet, or coming off the guide roller, which may affect work efficiency and The drawback is that the accuracy is not high enough.
他方、掘削直後の溝肩部は崩れ落ち易く、か・る現象も
また、掘削溝縁に盛り上がる排出土砂を再び溝底に落下
せしめる原因となっている。On the other hand, the groove shoulder immediately after excavation tends to collapse, and this phenomenon also causes discharged earth and sand that bulges on the edge of the excavated groove to fall back to the groove bottom.

するものである。This invention was developed to solve the above-mentioned problem of groove finishing edge mud treatment. A pair of raschel plates are arranged to protect the return side of the excavation packet chain, and the raschel plates support the excavation packet chain. Regardless of the depth of the excavation boom in the soil, the earth and sand on the edge of the groove are scraped away at the point where it touches the ground surface, and on the return side of the packet, each packet is prevented from getting caught up in obstacles on the edge of the groove, and the groove is It is an object of the present invention to provide a device with a grooved edge slough that prevents shoulder sagging.
以下、本考案を添附図面に示す具体例に基づき詳述する
。Hereinafter, the present invention will be described in detail based on specific examples shown in the accompanying drawings.
第１図は本考案に係る溝仕上縁泥掻き分は装置を備える
トレンチャ−の正面図で、第２図はその側面図である。FIG. 1 is a front view of a trencher equipped with a groove finishing edge scraping device according to the present invention, and FIG. 2 is a side view thereof.

砂を排出フード４を介して溝側前に排出して盛り上げる
。As is clear from the drawing, in front of the trencher main body T, there is an excavation boom 2 which can be raised and lowered by a first swing cylinder 1 via a swing arm 2a, and an excavation packet chain 3 rotates clockwise. The scooped up excavated earth and sand is discharged to the front of the trench side through a discharge hood 4 and heaped up.
この掘削パケットチェーン３の戻り側３ａには第２揺動
シリンダ６により揺動アーム６ａを介して昇降可能な溝
仕上装置５が下方に延びて配設され、掘削後の溝底を浚
うようになっている。On the return side 3a of the excavation packet chain 3, a trench finishing device 5 is disposed extending downward and is movable up and down via a swinging arm 6a by a second swinging cylinder 6, so as to dredge the trench bottom after excavation. It has become.

側３ａの両側を保護するように水平方向に延びる一対の
ラッセル板８，８を装着し、このラッセル板を装着した
昇降シリンダ７を上記掘削ブーム２を昇降させる第１揺
動シリンダ１と逆連動するように回路構成する。In the present invention, an elevating cylinder 7 is disposed on the back side of the groove finishing device 6, and a pair of raschel plates 8, 8 are provided at the lower end of the elevating cylinder 7 and extend horizontally so as to protect both sides of the return side 3a of the excavation packet chain 3. is installed, and a circuit is configured such that the lifting cylinder 7 equipped with this Russell plate is reversely interlocked with the first swing cylinder 1 that lifts and lowers the excavation boom 2.
これにより、まず第１揺動シリンダ１のみを作動させて

ブーム２の土中における深浅に関係なくラッセル板８は
地表に接した所で、溝縁の崩れを防止しつつ土砂を左右
に掻き分けるに最適な状態を保つことができる（第３図
参照）。As a result, first, only the first swing cylinder 1 is operated to lower the excavation boom 2 (see Fig. 6), and then, at the position where the Russell plate 8 touches the ground surface, this is detected visually or with a well-known detector. When the detection is detected and the lifting cylinder 7 is reversely linked (see Fig. 7), as the excavation boom 2 descends, the raschel plate 8 rises in proportion to the descent, so that the excavation boom 2 is adjusted to the depth and shallowness of the soil. Regardless, the raschel plate 8 can maintain the optimum condition at the place where it contacts the ground surface to move the earth and sand from side to side while preventing the groove edges from collapsing (see Fig. 3).
なお、地面が軟弱なところでオレンチャーを使用する場
合は、トレンチャ−を水平な状態に保つことが困難であ
るので、溝仕上装置をトレンチャ−の傾斜に伴って上下
させる装置を設ける。When using the trencher in a place where the ground is soft, it is difficult to keep the trencher in a horizontal state, so a device is provided to move the trench finishing device up and down as the trench slopes.

うにトレンチャ−Ｔが前方に傾斜してラッセル板８が溝
内に侵入しようとしても溝仕上装置５とともに所定個所
まで引き上げられるので、ラッセル板８は地表に接する
地点に保持される。In this case, if a mercury switch is arranged on the swing arm 6a to automatically raise and lower the groove finishing device 5 as described in Japanese Utility Application No. 53-024560, the trench finishing device 5 can be moved up and down automatically as shown in FIG. Even if the -T tilts forward and the Russell plate 8 attempts to enter the groove, it is pulled up together with the groove finishing device 5 to a predetermined position, so that the Russell plate 8 is held at the point where it contacts the ground surface.
他方、第５図に示すように、トレンチャ−Ｔの前方が浮
き上がってラッセル板８が地表から離れようとしても溝
仕上装置５とともに所定個所まで引き上げられるので、
ラッセル板８はトレンチャ−Ｔの傾斜に関係なく、地表
に接する地点に保持することができる。On the other hand, as shown in FIG. 5, even if the front part of the trencher T lifts up and the raschel plate 8 attempts to leave the ground, it will be pulled up to a predetermined position together with the groove finishing device 5.
The Russell plate 8 can be held at a point in contact with the ground surface regardless of the inclination of the trench T.

るので、掘削作業が迅速に行われることになる。As is clear from the above explanation, according to the present invention, the Russell plate held at the point in contact with the ground surface not only prevents packets from getting caught on the return side 3a of the excavation packet chain 3, but also prevents collapse of the groove shoulder. The excavation work can be carried out quickly because the excavated earth and sand piled up on the edge of the trench can be swept from side to side while preventing this.
