【考案の詳細な説明】
本考案は、アッパカット式溝掘機に設けられた排土装置
の改良に関する。[Detailed Description of the Invention] The present invention relates to an improvement of an earth removal device provided in an upper cut trench excavator.
通常、アッパカット式溝掘機においては爪を有する回転
ドラムで土を掘削し、両側の側部カバーで溝の両側方へ
飛散する土を案内し、且つこの側部カバーに設けた排土
板で土が溝へ戻らないように排土している。Normally, in an upper-cut trench excavator, soil is excavated using a rotating drum with claws, and side covers on both sides guide the soil scattered to both sides of the trench, and soil removal plates are installed on the side covers. The soil is removed to prevent it from returning to the ditch.
従来の排土板は、例えば第１図Ａに示すような長方形又
は正方形に形成されており、溝Ｇの側方へ排出された土
の多くをより遠くへ押しやるので排土抵抗が大きく、ま
た溝Ｇの際に柔がい排土が残り、更に溝Ｇを形成してい
る土壌のがた部Ｐも極めて崩れ易い状態となって残って
おり、少しの振動で、かた部Ｐの土壌が排土と共に崩れ
落ちることがあった。Conventional soil removal plates are formed into rectangular or square shapes, for example, as shown in Figure 1A, and push much of the soil discharged to the side of the trench G further away, resulting in large soil removal resistance. Soft soil remains at the time of trench G, and the soil gap P that forms trench G remains in an extremely fragile state, and even a slight vibration causes the soil in corner P to collapse. Sometimes it collapsed when the soil was removed.
本考案は、このような問題点に鑑み、排上板の下端を作
業方向後方へ傾斜させて、土を押えながら排土し、且つ
前記下端の溝掘機側を土壌と略平行にして溝のかた部の
排土量を少なくし、これによって排土抵抗を少なくし且
つ溝への土洩れをなくすように構成した溝掘機の排土装
置を提供することを目的とする。In view of these problems, the present invention has been developed by tilting the lower end of the discharging plate backward in the working direction, discharging the soil while holding down the soil, and placing the lower end on the trenching machine side approximately parallel to the soil to form the trench. To provide an earth removal device for a trench excavator configured to reduce the amount of earth removed at the side part, thereby reducing earth removal resistance and eliminating earth leakage into a trench.
この目的を達成するための本考案の特徴は、アッパカッ

斜した傾斜部をその中途部から外端まで形成した排土装
置において、前記平行部及び傾斜部は作業方向後下方へ
傾斜している点にある。A feature of the present invention to achieve this purpose is that the side covers on both sides of the upper-cut trench excavator are equipped with earth removal plates that can be vertically adjusted, and the lower end of each earth removal plate is placed approximately parallel to the soil surface. In an earth removal device in which a parallel portion is formed from its inner end to a halfway point, and a sloped portion that slopes outward and upward is formed from the halfway point to its outer end, the parallel portion and the sloped portion are sloped backward and downward in the working direction. The point is that it is.

れのない良好な溝を形成することができる。The parallel part and the inclined part at the lower end of the earth removal plate are inclined backward and downward in the working direction, so the soil on the side of the groove is compacted by the parallel part and pushed outward, while being formed into a mountain shape by the inclined part. Because it can be compacted and the soil can only be released backwards,
Compaction is easy, soil removal resistance is low, and it is possible to form a good groove without any collapse or soil leakage.
