TRENCH EXCAVATOR
PROBLEM TO BE SOLVED: To provide a trench excavator capable of preventing an excavated groove from being closed by excavated soil, not worsening a drainage property, and keeping a drainage function of the excavated groove reliably.SOLUTION: A trench excavator includes: a stabilization member 22 in a machine frame 3, the stabilization member capable of contacting slidably field upper edge faces W, Wand in-groove side faces W, Wforming both right/left upper corner edge parts of an excavated groove W excavated by a raking member 11; and a drop prevention member 26 in the stabilization member, the drop prevention member preventing drop of excavated soil D laterally discharged by the raking member into the excavated groove.SELECTED DRAWING: Figure 5
【課題】掘取土による掘取溝内の閉塞を防ぐことができ、水はけ排水性を妨げることがなくなり、掘取溝の排水機能を確実に保持することができる。【解決手段】機枠３にすき部材１１により掘り取られた掘取溝Ｗの左右の両上角縁部を形成する圃場上縁面Ｗ１・Ｗ１及び溝内側面Ｗ２・Ｗ２に摺接可能な安定部材２２を設け、安定部材に上記すき部材により側方に排出された掘取土Ｄの上記掘取溝内への落ち込みを防ぐ落込防止部材２６を設けてなる。【選択図】図５
