PROBLEM TO BE SOLVED: To provide a rotary tilling device configured so that soil can be prevented from adhesion on a rotary cover by a simple structure.SOLUTION: A rotary tilling device includes a soil adhesion prevention body 9 provided on a surface at the side of a rotary tilling body 6 of a rotary cover 7. The soil adhesion prevention body 9 is configured so that an elastic board 90 is folded in the longitudinal direction of a traveling direction to have a circular arc-shaped bulge and mounted to the rotary cover 7. By this structure, the circular arc-shaped bulge part is vibrated more easily, and therefore it is structured that the soil is hard to adhere and falls easily even if it adheres. Also, in the rotary tilling device, the circular arc-shaped bulge part 92 of the elastic board 90 of the soil adhesion prevention body 9 is mounted so as to be positioned in the downstream side of the rotation direction of the rotary tilling body 6.SELECTED DRAWING: Figure 4 |
