<p>PURPOSE:To provide a lawn grass cutting draining device with simple mechanism by having a cutting part in the rear part of a motive power unit for rubber tire, vertically moving an iron-working cutter body mounted thereon to cut lawn grass, cutting a groove, and burying a pipe body therein together with pumice. CONSTITUTION:While a motive power unit for rubber tire is advanced at minute speed, a cutting part 3 formed of a base 31 mounted on a car body rear part; a cutting tool mounting member 32; a parallel link 33; and a hydraulic cylinder 34 is vertically moved by hydraulic operation. An iron-working cutter body 4 mounted on the cutting tool 3 has a form having an edge form on the advancing side and a camber toward the rear part, and cuts a groove while cutting lawn grass and surface earth, and the soil is once discharged by a soil discharging plate 14. In the cut groove, a pipe body 9 guided by a pipe body feed roller 10 is laid so that it is enclosed by the pumice supplied from a hopper 5. After laying, the discharged soil is back filled by a soil collecting plate 16, and compacted by a compaction roller 12.</p> |
