PROBLEM TO BE SOLVED: To provide an implement for burying a material in a groove to improve soil, which does not need to load the material on the implement, can work only with the power of a traction work machine, can adjust the amount of the soil-improving material used, a burying distance, and a burying depth, minimizes the disturbance of soil, and has high workability and low cost.SOLUTION: There is provided the implement for burying a material in a groove which is pulled by a work vehicle and is used for cut soil into a soil block having an inverted trapezoidal cross-section by a soil-cutting support 20B traveling in the target soil, a side space-holding plate 20C having a soil-cutting blade, and a soil block-lifting slide plate 20D, supporting the soil block by the slide plate 20D and the holding plate 20C, simultaneously obliquely upward lifting the soil block by the slide plate 20D along the support 20B, forming a side cavity on the back side of the holding plate 20C, forming a bottom cavity below the slide plate 20D, dropping and charging an arranging material laid on the surface of the soil into the cavities by a material-collecting and charging machine, and then returning the soil block into the cavities, thereby, charging the material into the soil to form an L-shaped vertical groove.COPYRIGHT: (C)2011,JPO&INPIT【課題】機械に資材を積込む必要がなく、一台の牽引作業機の動力だけで作業ができ、土壌改良資材の使用量や埋設する間隔と深さの調整でき、土壌の攪乱を最小限に抑えた、高い施工性と低コストを具備した土壌改良のための資材溝埋設機を提供する。【解決手段】作業車で牽引され、対象土壌中を進行する土壌切断刃支柱20Bと、土壌切断刃付き側方空間保持板20Cと、土壌ブロック持上げスライド板20Dにより対象土壌を逆台形状断面の土壌ブロックに切断し、土壌ブロックをスライド板20Dと保持板20Cで支えながら、スライド板20Dにより支柱20Bに沿って斜め上方に持上げ、保持板20Cの裏側に側方空洞、スライド板20Dの下方に底部空洞を構築し、資材収集投入機により、土壌表面に敷設された配置資材を前記空洞に落下投入し、土壌ブロックを埋戻すことにより、土壌中に配置資材が投入されたL字形状縦溝を形成する資材溝埋設機を提供する。【選択図】図4
