COMPACTION MACHINE
PROBLEM TO BE SOLVED: To expand a compacted range further deeper to improve the compaction efficiency.SOLUTION: A hand guide roller 10 is provided, in the front and rear of a car body, with a drum-shaped rolling compaction wheel 40 having a concave portion 41 which is dented smoothly at the center in the direction of a rotational axis AR by tapered portions 41a, 41b, and a top-shaped rolling compaction wheel 50 having a protuberance 51 which protrudes smoothly at the center in the direction of a rotational axis AR2 by tapered portions 51a, 51b. Then, the taper portions 41a, 41b constituting the concave portion 41 of the rolling compaction wheel 40 and the tapered portions 51a, 51b constituting the protuberance 51 of the rolling compaction wheel 50 move soil particles in the longitudinal direction, so that a compacted range expands in the depth direction.SELECTED DRAWING: Figure 2
【課題】締固められる範囲をより深部に拡大し、締固め効率を向上させる。【解決手段】ハンドガイドローラ１０は、回転軸ＡＲ方向の中央にテーパー部分４１ａ，４１ｂによってなだらか凹む凹み部４１を有する鼓型の転圧輪４０と、回転軸ＡＲ２方向の中央にテーパー部分５１ａ，５１ｂによってなだらかに出っ張る出っ張り部５１を有する独楽型の転圧輪５０とを車体前後に備える。そして、転圧輪４０の凹み部４１を構成するテーパー部分４１ａ，４１ｂ、転圧輪５０の出っ張り部５１を構成するテーパー部分５１ａ，５１ｂによって土粒子が左右方向に移動することで、締固め範囲が深度方向により拡大する。【選択図】図２
