PROBLEM TO BE SOLVED: To provide a surface soil scraping machine that can remove a contaminated surface soil to a depth with good accuracy in a labor-saving and efficient manner by a configuration capable of keeping a production cost low.SOLUTION: A surface soil scraping machine 21 is mounted on a traveling machine 11 and used. The surface soil scraping machine includes: an excavation unit 61 provided in the direction substantially parallel to the ground surface and intersecting with the traveling direction of the traveling machine 11, and having an excavation claw rotationally driven and scraping the surface soil of the ground surface a recovery unit positioned on the rear side of the traveling direction from the excavation unit 61 and provided substantially in parallel to the ground surface, and having a recovery blade for scooping the scraped soil a soil collecting unit 85 provided with a discharge port at the rear side of the recovery unit and having a soil collecting blade 86 for collecting the discharged soil in the shape of embankment narrower than the width of the excavation unit 61 and a roller 92 having a rotating shaft in the direction intersecting with the traveling direction and pressing the excavated excavation lower end surface in the lower part of the recovery unit.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】生産コストを低く抑えることができる構成で、汚染された表土を省力的かつ効率的に精度よい深さに取り除くことができる表土削り取り機を提供する。【解決手段】走行機11に装着されて使用される表土削り取り機21であって、地表面と略平行かつ走行機11の進行方向と交差する方向に設けられ、回転駆動して地表面の表土を削り取る掘削爪を有する掘削部61と、掘削部61よりも進行方向の後方側に位置して地表面と略平行に設けられ、削り取られた土壌を掬い上げる回収ブレードを有した回収部と、回収部後方側は排出口が設けられていて、排出された土壌を掘削部61幅より狭い盛土状に集土する集土ブレード86を有した集土部85と、回収部下方部には、進行方向と交差する方向に回転軸を有し、掘削された掘削下端面部を押圧するローラ92が備えられている表土削り取り機による。【選択図】 図1
